-
- *) SECURITY: CVE-2009-3555 (cve.mitre.org)
- mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
- attack when compiled against OpenSSL version 0.9.8m or later. Introduces

-
- *) SECURITY: CVE-2009-3555 (cve.mitre.org)
- mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
- for OpenSSL versions prior to 0.9.8l; reject any client-initiated
- renegotiations. Forcibly disable keepalive for the connection if there
- is any buffered data readable. Any configuration which requires
- renegotiation for per-directory/location access control is still

- Reported by SecurityReason. [Mark Cox, Joe Orton]
-
- *) SECURITY: CVE-2007-5000 (cve.mitre.org)
- mod_imap: Fix a cross-site scripting issue. Reported by JPCERT.
- [Joe Orton]
-
- *) Introduce the ProxyFtpDirCharset directive, allowing the administrator
- to identify a default, or specific servers or paths which list their
- contents in other-than ISO-8859-1 charset (e.g. utf-8). [Ruediger Pluem]
-
- *) log.c: Ensure Win32 resurrects its lost robust logger processes.
- [William Rowe]

-
- *) mod_ssl: Version reporting update; displays 'compiled against'
- Apache and build-time SSL Library versions at loglevel [info],

- info tags. Helps to identify a mod_ssl built against one flavor
- of OpenSSL but running against another (also adds SSL-C version
- number reporting.) [William Rowe]
-
- *) mod_autoindex: Add in Type and Charset options to IndexOptions
- directive. This allows the admin to explicitly set the
- content-type and charset of the generated page and is therefore
- a viable workaround for buggy browsers affected by CVE-2007-4465
- (cve.mitre.org). [Jim Jagielski]
-

- Ruediger Pluem]
-
- *) log core: fix the new piped logger case where we couldn't connect
- the replacement stderr logger's stderr to the NULL stdout stream.
- Continue in this case, since the previous alternative of no error
- logging at all (/dev/null) is far worse. [William Rowe]
-
- *) mpm_winnt: Prevent the parent-child pipe from leaking into other
- spawned processes, and ensure we have a /Device/null handle for
- stdout when running as-a-service. [William Rowe]
-
- *) ApacheMonitor: Fix Windows Vista detection. [Mladen Turk]
-
- *) mod_so: Solve dev's confusion by reporting expected/seen module
- magic signatures when failing with a 'garbled' message, and solve
- user's confusion by pointing out 'perhaps compiled for a different
- version of apache?'. [William Rowe]
-
- *) mod_ssl: initialize thread locks before initializing the hardware
- acceleration library, so the latter can make use of the former.
- PR 20951. [<adunn ncipher.com>]

- *) mod_isapi: Return 0 (failure) for more of the various ap_pass_brigade
- attempts to stream the response at the client. Log these as well.

-
- *) Allow 'make install DESTDIR=/path'. This allows packagers to install
- into a directory different from the one that was configured. This
- also mirrors the root= feature from 1.3. We cannot use prefix=,

-
- *) Fix install-bindist.sh so that it finds any perl instead of just
- early perl 5.x versions. This is consistent with a build/install

-
- *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
- the service, mpm and logging code, and bugs in apr_file_open_stderr

- *) Allow statically linked support binaries with the new

- do only one stat() call when generating the directory listings.
- [Justin Erenkrantz]
-
- *) Fix resolve_symlink to save the original symlink name if known.
- [Justin Erenkrantz]
-
- *) Be a bit more sane with regard to CanonicalNames. If the user has
- specified they want to use the CanonicalName, but they have not
- configured a port with the ServerName, then use the same port that
- the original request used. [Ryan Bloom and Ken Coar]
-
- *) In core_input_filter, check for an empty brigade after
- APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
- client says it will post some data but we get FIN before any
- data arrives. [Jeff Trawick]
-
- *) Not being able to bind to the socket is a fatal error. We should
- print an error to the console, and return a non-zero status code.

-
- *) The Location: response header field, used for external
- redirect, *must* be an absoluteURI. The Redirect directive
- tested for that, but RedirectMatch didn't -- it would allow
- almost anything through. Now it will try to turn an abs_path
- into an absoluteURI, but it will correctly varf like Redirect
- if the final redirection target isn't an absoluteURI. [Ken Coar]

-Changes with Apache 2.0.31
-
- *) Create the scoreboard (in the parent) in a global pool context,
- so it survives graceful restarts. This fixes a SEGV during
- graceful restarts. [Aaron Bannert]
-
- *) Add a timeout option to the proxy code 'ProxyTimeout'
- [Ian Holsman]
-
- *) FTP directory listings are now always retrieved in ASCII mode.
- The FTP proxy properly escapes URI's and HTML in the generated
- listing, and escapes the path components when talking to the FTP
- server. It is now possible to browse the root directory by using
- a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
- Also, the last path component may contain wildcard characters
- '*' and '?', and if they do, a directory listing is created instead
- of a file retrieval. Example: ftp://user@host/httpd/server/*.c

- *) Don't let the default handler try to serve a raw directory. At
- best you get gibberish. Much worse things can happen depending

-
- *) Change the pre_config hook to return a value. Modules can now emit
- an error message and then cause the server to quit gracefully during
- startup. This required a bump to the MMN. [Aaron Bannert]
-
- *) Fix some unix socket descriptor leaks in the handler side of
- mod_cgid (the part that runs in the server process). Whack a
- silly "close(-1)" in the handler too. [Jeff Trawick]
-
- *) Change the pre_mpm hook to return a value, so that scoreboard
- init errors percolate up to code that knows how to exit
- cleanly. This required a bump to the MMN. [Jeff Trawick]
-
- *) Add the socket back to the conn_rec and remove the create_connection
- hook. The create_connection hook had a design flaw that did not
- allow creating connections based on vhost info. [Bill Stoddard]
-
- *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
- Resolves the common case of using negotation to resolve the request
- /script/foo for /script.cgi/foo. [William Rowe]

- [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
-
- *) Fix a problem in the parsing of the <Proxy foo> directive.
- [Jeff Trawick]
-
- *) rewrite of mod_ssl input filter for better performance and less
- memory usage [Doug MacEachern]
-
- *) allow quick_handler to be run on subrequests. [Ian Holsman]
-
- *) mod_dav now asks its provider to place content directly into the
- filter stack when handling a GET request. The mod_dav/provider
- API has changed, so providers need to be updated. [Greg Stein]
-
- *) Clear the output socket descriptor in unixd_accept() to make sure
- we don't supply a bogus socket to the caller if the accept fails.
- This caused problems with the worker MPM, which tried to process
- the returned socket if it was non-NULL. [Brian Pane]
-
- *) Move a check for an empty brigade to the start of core input filter
- to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
-
- *) Add FileETag directive to allow configurable control of what
- data are used to form ETag values for file-based URIs. MMN
- bumped to 20020111 because of fields added to the end of
- the core_dir_config structure. [Ken Coar]
-
- *) Fix a segfault in mod_rewrite's logging code caused by passing the
- wrong config to ap_get_remote_host(). [Jeff Trawick]
-
- *) Allow mod_cgid to work from a binary distribution install by
- using 755 for the permissions on the log directory instead of
- 750. [Jeff Trawick]
-
- *) Fixed a segfault that happened during graceful shutdown (or when
- the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
-
- *) Split all Win32 modules [excluding the core components mod_core,
- mod_so, mod_win32 and the winnt mpm] into individual loadable
- modules, so the administrator may individually disable the former
- compiled-in modules by simply commenting out their LoadModule
- directives. [William Rowe]
-
- *) Saved Win32 module authors and porters many future headaches, by
- duplicating the appropriate .h files such as os.h into the include
- directory, including in the build tree. [William Rowe]
-
- *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
- Use SSL functions/macros instead of directly dereferencing SSL
- structures wherever possible.
- Add type-casts for the cases where functions return a generic pointer.
- Add $SSL/include to configure search path.
- [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
-
- *) Moved several pointers out of the shared Scoreboard so it is
- more portable, and will present the vhost name across server
- generation restarts. [William Rowe]
-
- *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
- [Doug MacEachern]
-
-Changes with Apache 2.0.30
-
- *) Fix the main bug for FreeBSD and threaded MPM's. There are
- still issues (see STATUS) but at least the server will now
- run without crashing the machine.
- [David Reid, Aaron Bannert, Justin Erenkrantz]
-
- *) Fix a typo in mod_deflate's m4 config section.
- [albert chin <china thewrittenword.com>]
-
- *) Fix a couple of mod_proxy problems forwarding HTTP connections
- and handling CONNECT:
- (1) PR #9190 Proxy failed to connect to IPv6 hosts.
- (2) Proxy failed to connect when the first IP address returned by
- the resolver was unreachable but a secondary IP address was.
- [Jeff Trawick]
-
- *) Fix the module identifer as shown in the docs for various core
- modules (e.g., the identifer for mod_log_config was previously
- listed as config_log_module). PR #9338
- [James Watson <ap2bug sowega.org>]
-
- *) Fix LimitRequestBody directive by placing it in the HTTP
- filter. [Justin Erenkrantz]
-
- *) Fix mod_proxy seg fault when the proxied server returns
- an HTTP/0.9 response or a bogus status line.
- [Adam Sussman]
-
- *) Prevent mod_proxy from truncating one character off the
- end of the status line returned from the proxied server.
- [Adam Sussman, Bill Stoddard]
-
- *) Eliminate loop in ap_proxy_string_read().
- [Adam Sussman, Bill Stoddard]
-
- *) Provide $0..$9 results from mod_include regex parsing.
- [William Rowe]
-
- *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
-
- *) Introduced the ForceLanguagePriority directive, to prevent
- returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
- when using Multiviews. [William Rowe]
-
- *) Fix a problem which prevented mod_cgid and suexec from working
- together reliably [Greg Ames]
-
- *) Remove the call to exit() from within mod_auth_digest's post_config
- phase. [Aaron Bannert]
-
- *) Fix a problem in mod_auth_digest that could potentially cause
- problems with initialized static data on a system that uses DSOs.
- [Aaron Bannert]
-
- *) Fix a segfault in the worker MPM that could happen during
- child process exits. [Brian Pane, Aaron Bannert]
-
- *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
-
- *) Fix matching of vhosts by ip address so we find IPv4
- vhost address when target address is v4-mapped form of
- that address. [Jeff Trawick]
-
- *) More performance tweaks to the BNDM string-search algorithm
- used to find "<!--#" tokens in mod_include [Brian Pane]
-
- *) Miscellaneous small performance fixes: optimized away various
- string copy operations and removed large temp buffers from
- the stack [Brian Pane]
-
- *) Fixed startup segfault that occurred when a VirtualHost
- directive had a port but no address [Brian Pane]
-
- *) Allow htdbm to work with multiple DBM types [Ian Holsman]
-
- *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
- if oslevel < WINNT. This should fix several problems reported
- Against 2.0.28 on Windows 98 [Bill Stoddard]
-
- *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
- to fail. [Bill Stoddard]
-
- *) Change core code to allow an MPM to set hard thread/server
- limits at startup. prefork, worker, and perchild MPMs now have
- directives to set these limits. [Jeff Trawick]
-
- *) Win32: The async AcceptEx() event should be autoreset upon
- successful completion of a wait (WaitForSingleObject). This
- eliminates a number of spurious
- setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
- [Bill Stoddard]
-
- *) Move any load library path environment variables out of
- apachectl and into a separate environment variable file which
- can be more easily tailored by the admin. The environment
- variable file as built by Apache may have additional system-
- specific settings. For example, on OS/390 we tailor the heap
- settings to allow lots of threads. [Jeff Trawick]
-
- *) Use the new APR pool code to reduce pool-related lock
- contention in the worker MPM. [Sander Striker]
-
- *) The POD no longer assumes the child is listening on 127.0.0.1
- and now pulls the first hostname in the list of listeners to
- perform the dummy connect on. This fixes a bug when the user
- had configured the Listen directive for an IP other than
- 127.0.0.1. This would result in undead children and error
- messages such as "Connection refused: connect to listener".
- [Aaron Bannert]
-
- *) The worker MPM now respects the LockFile setting, needed to
- avoid locking problems with NFS. [Jeff Trawick]
-
- *) Fix segfault when worker MPM receives SIGHUP.
- [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
-
- *) Fix bug that could potentially prevent the perchild MPM from
- working with more than one vhost/uid. [Aaron Bannert]
-
- *) Change make install and apxs -i processing of DSO modules to
- perform special handling on platforms where libtool doesn't install
- mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
- which prevented standard LoadModule statements from working.
- [Jeff Trawick]
-
- *) Whenever mod_so is enabled (not just when there are DSOs for
- our modules), do whatever special magic is required for compiling/
- loading third-party modules. This allows third-party DSOs to
- be used on an AIX build when there were no built-in modules
- built as DSOs. (This should help on OS/390 and BeOS as well.)
- [Jeff Trawick]
-
- *) Allow apxs to be used to build DSOs on AIX without requiring the
- user to hard-code the list of import files. (This should help
- on OS/390 and BeOS as well.) [Jeff Trawick]
-
- *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
- PR 8563, 8919 [William Rowe]
-
- *) Get binary builds working when libapr and libaprutil are built
- shared [Greg Ames]
-
- *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
- working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
- Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
-
- *) Fix the handling of SSI directives in which the ">" of the
- terminating "-->" is the last byte in a file [Brian Pane]
-
- *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
- message that we had back in apache-1.3 and still have scattered
- throughout our docs. [Aaron Bannert]
-
- *) Prevent the Win32 port from continuing after encountering an
- error in the command line args to apache. [William Rowe]
-
- *) On a error in the proxy, make it write a line to the error log
- [Ian Holsman]
-
- *) Various mod_ssl performance improvements [Doug MacEachern]
-
-Changes with Apache 2.0.29
-
- *) Add buffering in core_output_filter to ensure that long
- lists of small buckets don't cause small packet writes.
- [Brian Pane, Ryan Bloom]
-
- *) Fix the installation target to make sure that the manual is
- installed in the correct location.
- [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
- Gomez Henri <hgomez slib.fr>]
-
- *) Fix the cmd command for mod_include. When we are processing
- a cmd command, we do not want to use the r->filename to set
- the command name. The command comes from the SSI tag. To do this,
- I added a variable to the function that builds the command line
- in mod_cgi. This allows the include_cmd function to specify
- the command line itself. [Ryan Bloom]
-
- *) Change open_logs hook to return a value, allowing you
- to flag a error while opening logs
- [Ian Holsman, Doug MacEachern]
-
- *) Change post_config hook to return a value, allowing you
- to flag a error post config
- [Ian Holsman, Jeff Trawick]
-
- *) Allow SUEXEC_BIN (the path to the suexec binary that is
- hard-coded into the server) to be specified to the configure
- script by the --with-suexec-bin parameter. [Aaron Bannert]
-
- *) Fix segv in worker MPM following accept on pipe-of-death
- [Brian Pane]
-
- *) Add mod_deflate to experimental.
- [Ian Holsman, Justin Erenkrantz]
-
- *) Bail out at configure time if an invalid MPM was specified.

- *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
-
- *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
-
- *) Optimization for the BNDM string-search function in
- mod_include. [Brian Pane]
-
- *) Fixed the behavior of the XBitHack directive.
- [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
-
- *) The threaded MPM for Unix has been removed. Use the worker
- MPM instead. [various]
-
- *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
- in logging the error from a failed DNS lookup. [Jeff Trawick]
-
- *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
- [Cliff Woolley]
-
- *) Get mod_cgid killed when a MPM exits due to a fatal error.
- [Jeff Trawick]
-
- *) Fix a file descriptor leak in mod_include. When we include a
- file, we use a sub-request, but we didn't destroy the sub-request
- immediately, instead we waited until the original request was
- done. This patch closes the sub-request as soon as the data is
- done being generated. [Brian Pane <bpane pacbell.net>]
-
- *) Allow modules that add sockets to the ap_listeners list to
- define the function that should be used to accept on that
- socket. Each MPM can define their own function to use for
- the accept function with the MPM_ACCEPT_FUNC macro. This
- also abstracts out all of the Unix accept error handling
- logic, which has become out of synch across Unix MPMs.
- [Ryan Bloom]
-
- *) Fix a bug which would cause the response headers to be omitted
- when sending a negotiated ErrorDocument because the required
- filters were attached to the wrong request_rec.
- [John Sterling <sterling covalent.net>]
-
- *) Remove commas from the end of the macros that define
- directives that are used by MPMs. Prior to this patch,
- you would use these macros without commas, which was unlike
- the macros for any other directives. Now, the caller provides
- the comma rather than the macro providing it. This makes
- the macros look more like the rest of the directives.
- [Ryan Bloom and Cliff Woolley]
-
- *) Add 'redirect-carefully' environment option to disable sending
- redirects under special circumstances. This is helpful for
- Microsoft's WebFolders when accessing a directory resource via
- DAV methods. [Justin Erenkrantz]
-
- *) Begin to abstract out the underlying transport layer.
- The first step is to remove the socket from the conn_rec,
- the server now lives in a context that is passed to the
- core's input and output filters. This forces us to be very
- careful when adding calls that use the socket directly,
- because the socket isn't available in most locations.
- [Ryan Bloom]
-
- *) Really reset the MaxClients value in worker and threaded
- when the configured value is not a multiple of the number
- of threads per child. We said we did previously but we
- forgot to. [Jeff Trawick]
-
- *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
-
- *) If shared modules are requested and mod_so is not available,
- produce a fatal config-time error. [Justin Erenkrantz]
-
- *) Improve http2env's performance by cutting the work it has to
- do. [Brian Pane <bpane pacbell.net>]
-
- *) use new 'apr_hash_merge' function in mod_mime (performance fix)
- [Brian Pane <bpane pacbell.net>]
-
-Changes with Apache 2.0.28
-
- *) Fix infinite loop in mod_cgid.c.
- [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
-
- *) When no port is given in a "ServerName host" directive, the
- server_rec->port is now set to zero, not 80. That allows for
- run-time deduction of the correct server port (depending on
- SSL/plain, and depending also on the current setting of
- UseCanonicalName). This change makes redirections
- work, even with https:// connections. As in Apache-1.3, the
- connection's actual port number is never used, only the ServerName
- setting or the client's Host: setting. Documentation updated
- to reflect the change. [Martin Kraemer]
-
- *) Add a '%{note-name}e' argument to mod-headers, which works in
- the same way as mod_log_confg. [Ian Holsman]
-
- *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
- AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
- MPMs. [Cliff Woolley]
-
- *) Introduce htdbm, a user management utility for db/dbm authorization
- databases. [Mladen Turk <mturk mappingsoft.com>]
-
- *) Optimize usage of strlen and strcat in ap_directory_walk.
- [Brian Pane <bpane pacbell.net>]
-
-Changes with Apache 2.0.27
-
- *) Introduce an Apache mod_ssl initial configuration template
- (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
-
- *) Fixed a memory leak in the getline parsing code that could
- be triggered by arbitrarily large header lines. Requests
- from the core input filter for single lines are now limited
- to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
-
- *) Fix a truncation bug in how we print the port on the Via: header.
- The routine that prints the Via: header now takes a length for
- the port string. [Zvi Har'El <rl math.technion.ac.il>]
-
- *) Some syntax errors in mod_mime_magic's magic file can result
- in a 500 error, which previously was unlogged. Now we log the
- error. [Jeff Trawick]
-
- *) Add the support/checkgid helper app, which checks the run-time
- validity of group identifiers usable in the Group directive.
- [Ken Coar]
-
- *) Various --enable-so options have been fixed: --enable-so is
- treated as "static"; explicit --enable-so=shared issues an error;
- and explicit --enable-so fails with error on systems without
- APR_HAS_DSO. [Aaron Bannert]
-
- *) Fix a segfault in the core input filter when the client socket
- gets disconnected unexpectedly. [Cliff Woolley]
-
- *) Fix the reporting for child processes that die. This removes
- all of the non-portable W* macros from Apache.
- [Jeff Trawick and Ryan Bloom]
-
- *) Win32: Track and display "Parent Server Generation:" in
- mod_status output. The generation will be bumped at
- server graceful restart, when the child process exits
- by hitting MaxRequestsPerChild or if the child
- process exits abnormally. [Bill Stoddard]
-
- *) Win32: Fix problem where MaxRequestsPerChild directive was
- not being picked up in favor of the default. Enable
- the parent to start up a new child process immediately upon
- the old child starting shutdown.
- [Bill Stoddard]
-
- *) Fix some bungling of the remote port in rfc1413.c so that
- IdentityCheck retrieves the proper user id instead of failing
- and thus always returning "nobody."
- [Dick Streefland <Dick.Streefland xs4all.nl>]
-
- *) Introduced thread saftey for mod_rewrite's internal cache.
- [Brian Pane <bpane pacbell.net>]
-
- *) Simplified mod_env's directives to behave as most directives are
- expected, in that UnsetEnv will not unset a SetEnv and PassEnv
- directive following that UnsetEnv within the same container.
- Also provides a runtime startup warning if a PassEnv configured
- environment value is undefined. [William Rowe]
-
- *) The worker MPM is now completely ported to APR's new lock API. It
- uses native APR types for thread mutexes, cross-process mutexes,
- and condition variables. [Aaron Bannert]
-
- *) Sync up documentation to remove all references to the now deprecated
- Port directive. [Justin Erenkrantz]
-
- *) Moved all ldap modules from the core to httpd-ldap sub-project
- [Ryan Bloom]
-
- *) Exit when we can't listen on any of the configured ports. This
- is the same behavior as 1.3, and it avoids having the MPMs to
- deal with bogus ap_listen_rec structures. [Jeff Trawick]
-
- *) Cleanup the proxy code that creates a request to the origin
- server. This change adds an optional hook, which allows modules
- to gain control while the request is created if the proxy module
- is loaded. The purpose of this hook is to allow modules to add
- input and/or output filters to the request to the origin. While
- I was at it, I made the core use this hook, so that proxy request
- creation uses some of the code from the core. This can still be
- greatly improved, but this is a good start. [Ryan Bloom]
-
-Changes with Apache 2.0.26
-
- *) Port the MaxClients changes from the worker MPM to the threaded
- MPM. [Ryan Bloom]
-
- *) Fix mod_proxy so that it handles chunked transfer-encoding and works
- with the new input filtering system. [Justin Erenkrantz]
-
- *) Introduce the MultiviewsMatch directive, to allow the operator
- to be flexible in recognizing Handlers and Filters filename
- extensions as part of the Multiviews matching logic, strict with
- MultiviewsMatch NegotiatedOnly to accept only filename extentions
- that designate negotiated parameters, (content type, charset, etc.)
- or MultiviewsAll for the 1.3 behavior of matching any files, even
- if they have unregistered extensions. [William Rowe]
-
- *) Fixed the configure script to add a LoadModule directive to
- the default httpd.conf for any module that was compiled
- as a DSO. [Aaron Bannert <aaron clove.org>]
-
- *) rewrite mod_ssl input filtering to work with the new input filtering
- system. [Justin Erenkrantz]
-
- *) prefork: Don't segfault when we are able to listen on some but
- not all of the configured ports. [Jeff Trawick]
-
- *) Build mod_so even if no core modules are built shared.
- [Aaron Bannert <aaron clove.org>]
-
- *) Introduce ap_directory_walk rewrite (with further optimizations
- required) to adapt to the ap_process_request_internal() changes.
- Optimized so subrequests and redirects now reuse previous section
- merges, until we mismatch with the original directory_walk, and
- precomputed r->finfo results will cause directory_walk to skip
- the most expensive phases of the function. [William Rowe]
-
- *) Allow ApacheMonitor to connect to and control Apache on other
- WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
-
- *) Remove the Port directive. In it's place, the Listen directive
- is now a required directive, which tells Apache what port to
- listen on. The ServerName directive has also been extended
- to accept an optional port. If the port is specified to the
- ServerName, the server will report that port whenever it
- reports the port that it is listening on. This change was
- made to ease configuration errors that stem from having a Port
- directive, and a Listen directive. In that situation, the server
- would only listen to the port specified by the Listen command,
- which caused a lot of confusion to users. [Ryan Bloom]
-
- *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
- build, as loadable modules. [William Rowe]
-
- *) Fix --enable-mods-shared processing. If most is specified,
- then all modules that can be compiled as shared modules are.
- [Aaron Bannert <aaron clove.org>]
-
- *) Update the mime.types file to map video/vnd.mpegurl to mxu
- and add commonly used audio/x-mpegurl for m3u extensions.
- [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
-
- *) Eliminate the depreciated r->content_language, in favor of the array
- r->content_languages introduced many years ago. Module authors must
- substantially overhaul their modules, so this needs to be upgraded
- if the module still relied on backwards-brokeness. [William Rowe]
-
- *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
- [Justin Erenkrantz]
-
- *) Rewrite the input filtering mechanisms to consolidate and reorganize
- code. In short, core_input_filter does something now and
- ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
-
- *) Update the Win32 build to re-absorb mod_proxy and family.
- [William Rowe]
-
- *) Resolved the build failure on Win32 using MSVC 5.0 (without the
- current SDK.) [William Rowe]
-
- *) Some style changes to the code that does ProxyErrorOverride. Fixed
- config merge behaviour. [Graham Leggett]
-
- *) Allow support programs to be compiled against a static version
- of libapr. This allows the smaller support programs to be
- relocated. [Aaron Bannert <aaron clove.org>]
-
- *) Update the mime.types file to the registered media types as
- of 2001-09-25, and add mapping for xsl extension [Mark Cox]
-
- *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
- number of clients that can connect at the same time, instead of
- specifying the maximum number of child processes.
- [Aaron Bannert <aaron clove.org>]
-
- *) Switch proc_pthread AcceptMutex configuration directive to pthread to
- be consistent with 1.3. [Justin Erenkrantz]
-
- *) Cache apr_explode_localtime() value for 15 seconds.
- [Brian Pane <bpane pacbell.net>]
-
- *) Fix mod_include to not return ETag or Last-Modified headers.
- [Ian Holsman <ianh cnet.com>]
-
- *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
-
- *) Eliminate the wasteful run-time conversion of method names from strings
- to numbers in places where the methods are known at compile time.
- [Brian Pane <bpane pacbell.net>]
-
- *) Turn the worker MPM's queue into a LIFO. This may
- improve cache-hit performance under some conditions.
- [Aaron Bannert <aaron clove.org>]
-
- *) Switch back to SIGUSR1 for graceful restarts on all platforms that
- support it. [Justin Erenkrantz]
-
- *) Cleanup the worker MPM. We no longer re-use transaction
- pools. This incurs less overhead than shuffling the pools
- around so that they can be re-used. Remove one of the
- queue's condition variables. We just redefined the API to
- state that you can't try to add more stuff than you allocated
- segments for. [Aaron Bannert <aaron clove.org>]
-
- *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
-
- *) Fixed persistent connections when a request contains a body.
- [Greg Stein]
-
- *) mod_dav uses a new API to speak to the backend provider for dead
- property management. [Greg Stein]
-
- *) Remove the Win32 script-processing exception from mod_cgi, and
- roll build_command_line/build_argv_list into a unified, overrideable
- ap_cgi_build_command optional function. [William Rowe]
-
- *) Rewrite find_start_sequence to use a better search algorithm
- to find the start tag. [Justin Erenkrantz]
-
- *) Fix a seg fault in mod_include. When we are generating an
- internal redirect, we must set r->uri to "", not a bogus
- string, and not NULL. [Ryan Bloom]
-
- *) Optimized location_walk, so subrequests, redirects and second passes
- now reuse previous section merges on a <Location > by <Location >
- basis, until we mismatch with the original location_walk.
- [William Rowe]
-
- *) Back out the 1.45 change to util_script.c. This change made
- us set the environment variable REQUEST_URI to the redirected
- URI, instead of the originally requested URI.
- [Taketo Kabe <kabe sra-tohoku.co.jp>]
-
- *) Make mod_include do lazy evaluation of potentially expensive to
- compute variables. [Brian Pane <bpane pacbell.net>]
-
- *) Fix logging of bytes sent for HEAD requests. %b and %B should
- log either - or 0, before this patch, they were both logging
- the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
-
- *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
- than per character. [Brian Pane <bpane pacbell.net>]
-
- *) Normalize the primary request, redirects and sub-requests to
- run the same ap_process_request_internal for consistency in
- robustness, behavior and security. [William Rowe]
-
- *) Fix a segfault with mod_include when r->path_info is not set
- (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
-
- *) Add -X functionality back. This indicates to all MPMs and any other
- part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
-
- *) Some initial support for the cygwin platform [prefork only].
- This is not to be confused with support for the WinNT/Win32
- platform, which is the recommended configuration for native
- Win32 users. The cygwin platform support is recommended for
- cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
-
- *) Changed syntax of Set{Input|Output}Filter. The list of filters
- must be semicolon delimited (if more than one filter is given.)
- The Set{Input|Output}Filter directive now overrides a parent
- container's directive (e.g. SetInputFilter in <Directory /web/foo>
- will override any SetInputFilter directive in <Directory /web>.)
- This new syntax is more consistent with Add{Input|Output}Filter
- directives defined in mod_mime. Also cures a bug in prior releases
- where the Set{Input|Output}Filter directive would corrupt the
- global configuration if the multiple directives were nested.
- [William Rowe]
-
- *) Cured what's ailed mime for quite some time. If an AddSomething
- was given in the configuration (Language, Charset, Handler or
- Encoding) Apache would set the content type as given by AddType,
- but refused to check the mime.types file if AddType wasn't given
- for that specific extension. Setting the AddHandler for .html
- without setting the AddType text/html html would cause Apache to
- use the default content type. [William Rowe]
-
- *) Added some bulletproofing to memory allocation in the LDAP cache
- code. [Graham Leggett]
-
-Changes with Apache 2.0.25
-
- *) Move the installed /manual directory out of the /htdocs/ tree, so
- that it can be kept more independently from the remaining document
- root. The "Alias /manual ..." already allowed for easy projection
- into existing private document trees. [Martin Kraemer]
-
- *) Add specified user attributes to the environment when using
- mod_auth_ldap. This allows you to use mod_include to embed specified
- user attributes in a page like so:
- Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
- [Graham Leggett]
-
- *) Fix a performance problem with the worker MPM. We now create
- transaction pools once, and re-use them for each connection.
- [Aaron Bannert <aaron clove.org>]
-
- *) Modfied mod_mime to prevent mod_negotation from serving a multiview
- of a 'handler' or 'filter', so that any filename extension that does
- not contribute to the negotiated metadata can't be served without
- an explicit request. E.g., if the .Z extension is associated with
- an unzip filter, the user request somefile.Z.html, mod_negotiation
- won't serve it. It can serve somefile.Z.html when somefile.Z is
- requested, since the .Z extension is explictly requested, if the
- .html extension is associated with ContentType text/html.
- [William Rowe]
-
- *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
- and corresponding AddOutputFilter syntax, to insert one or more
- filters by mod_mime filename extension processing.
- [William Rowe]
-
- *) Fix a growing connection pool in core_output_filter() for
- keepalive requests. [Jeff Trawick]
-
- *) Moved split_and_pass_pretag_buckets back to being a
- macro at Ryans's request. Removed the return from it
- by setting and returning a return code instead. Updated
- the code to check the return code from the macro and
- do the right thing. [Paul J. Reder]
-
- *) Fix a segfault when a numeric value was received for Host:.
- [Jeff Trawick]
-
- *) Add a function ap_remove_input_filter. This is to match
- up with ap_remove_output_filter. [Ryan Bloom]
-
- *) Clean up location_walk, so that this step performs a minimum
- amount of redundant effort (it must be run twice, but it will no
- longer reparse all <Location > blocks when the request uri
- hadn't changed.) [William Rowe]
-
- *) Eliminate proxy: (and all other 'special') processing from the
- ap_directory_walk() phase. Modules that want to use special
- walk logic should refer to the mod_proxy map_to_location example,
- with it's proxy_walk and proxysection implementation. This makes
- either directory_walk flavor much more legible, since that phase
- only runs against real <Directory > blocks.
- [William Rowe]
-
- *) SECURITY: Fix a security problem in mod_include which would allow
- an SSI document to be passed to the client unparsed.
- [Cliff Woolley, Brian Pane]
-
- *) Introduce the map_to_storage hook, which allows modules to bypass
- the directory_walk and file_walk for non-file requests. TRACE
- shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
- directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
- [William Rowe]
-
- *) Add the ability for mod_include to add the INCLUDES filter
- if the file is configured for the server-parsed handler.
- This makes the configuration for .shtml files much easier
- to understand, and allows mod_include to honor Apache 1.3
- config files. Based on Doug MacEachern's patch to PHP
- to do the same thing. [Ryan Bloom]
-
- *) force OpenSSL to ignore process local-caching and to always
- get/set/delete sessions using mod_ssl's callbacks
- [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
- Geoff Thorpe <geoff geoffthorpe.net>]
-
- *) Make the worker MPM shutdown and restart cleanly. This also
- cleans up some race conditions, and gets the worker using
- pools more cleanly. [Aaron Bannert <aaron clove.org>]
-
- *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
- for mod_ssl
- [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
-
- *) Fix for mod_include. Ryan's patch to check error
- codes put a return in the wrong place. Also, the
- include handler return code wasn't being checked.
- I don't like macros with returns, so I converted
- SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
- [Paul J. Reder <rederpj raleigh.ibm.com>]
-
- *) fix segv in mod_mime if no AddTypes are configured
- [John Sterling <sterling covalent.net>]
-
- *) Enable ssl client authentication at SSL_accept time
- [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
-
- *) Fix a segfault in mod_include when the original request has no
- associated filename (e.g., we're filtering the error document for
- a bad URI). [Jeff Trawick]
-
- *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
-
- *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
- of httpd is started and shuts down due to socket conflict. Moving the
- call to ap_log_pid solves the problem.
-
- *) Changed the late-1.3 log_config substitution %c to %X, to log the
- status of the closed connection, as it conflicts with the far more
- common, historical ssl logging directive %...{var}c. [William Rowe]
-
- *) Added the common error/ tree to the build/install targets
- (similar to the common icons/ tree) for the multi-language error
- messages that Lars committed earlier. [William Rowe]
-
- *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
-
- *) Added a default commented-out mod_ldap and mod_auth_ldap
- configuration to httpd-std.conf and httpd-win.conf
- [Graham Leggett]
-
- *) Added documentation for mod_ldap and mod_auth_ldap.
- [Graham Leggett]
-
- *) Enabled negative caching on attribute comparisons in the LDAP cache.
- Fixed a problem where the default cache TTL was set in milliseconds
- not microseconds causing the cache to time out almost immediately.
- [Graham Leggett]
-
- *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
- module code to follow APR. [Graham Leggett]
-
- *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
- cleaned up when the connection pool pool is cleaned up.
- [Graham Leggett]
-
- *) Fix a minor issue with Jeff Trawick's mod_include
- patch. Without this patch, the code will just allocate
- more bytes in get_combined_directive than are needed.
- [Paul Reder]
-
- *) Added the LDAP authentication module mod_auth_ldap.
- [Dave Carrigan <dave rudedog.org>, Graham Leggett]
-
- *) Added the LDAP cache and connection pooling module mod_ldap.
- [Dave Carrigan <dave rudedog.org>, Graham Leggett]
-
- *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
- by allowing a module to disable itself if its prerequisites are not
- met. [Justin Erenkrantz]
-
-Changes with Apache 2.0.24
-
- *) Fix a couple of issues in mod_include when the tag appeared at
- offsets near 8192 in the file being parsed. [Jeff Trawick]
-
- *) Fix an assertion failure in mod_ssl when the keepalive timeout is
- reached. [Jeff Trawick]
-
- *) Numerous improvements to the Win32 build system. Introduced command line
- builds without requiring .mak files for MSVC 6.0 and later versions.
- Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
- [William Rowe]
-
- *) Assorted corrections and improvements to the winnt_mpm startup code. Better
- reporting of uninstalled services and other error conditions, and changed the
- default service name to Apache2. [William Rowe]
-
- *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
- compatibility with existing Apache 1.3 Win32 Apache management utilites.
- [Mladen Turk <mturk mappingsoft.com>, William Rowe]
-
- *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
- [William Rowe, Greg Ames]
-
- *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
- and RemoveCharset directives. [William Rowe]
-
- *) The Unix MPMs other than perchild now allow child server
- processes to use the accept mutex when starting as root and
- using SysV sems for the accept mutex. Previously, this
- combination would lead to fatal errors in the child server
- processes. perchild can't use SysV sems because of security
- issues. [Jeff Trawick, Greg Ames]
-
- *) Added Win32 revision stamp resources to all http binaries
- (including modules/ and support/ tools.) PR7322 [William Rowe]
-
- *) Fix ap_rvprintf to support more than 4K of data at one time.
- [Cody Sherr <csherr covalent.net>]
-
- *) We have always used the obsolete/deprecated Netscape syntax
- for our tracking cookies; now the CookieStyle directive
- allows the Webmaster to choose the Netscape, RFC2109, or
- RFC2965 format. The new CookieDomain directive allows the
- setting of the cookie's Domain= attribute, too. PR #s 5006,
- 5023, 5920, 6140 [Ken Coar]
-
- *) Tweak server/Makefile so that the rules for generating exports.c
- are compatible with make utilities which don't expand wildcards
- in a dependency list (e.g., OS/390 make, certain levels of GNU
- make). [Jeff Trawick]
-
- *) Install the SSL headers. [John Sterling <sterling covalent.net>]
-
- *) Begin to sanitize the MPM configuration directives. Now, all
- MPMs use the same functions for all common MPM directives. This
- should make it easier to catch all bugs in these directives once.
- [Cody Sherr <csherr covalent.net>]
-
- *) Close a major resource leak. Every time we had issued a
- graceful restart, we leaked a socket descriptor.
- [Ryan Bloom]
-
- *) Fix a problem with the new method code. We need to cast
- the 1 to an apr_int64_t or it will be treated as a 32-bit
- integer, and it will wrap after being shifted 32 times.
- [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
-
- *) Fix a bug in mod_expires. Previous to this patch, if you
- told mod_expires to add 604800 seconds to the last-modified
- time, it actually added 604800 usec's to the last-modified time,
- so that when looking at the response it looked like nothing
- had been done. The root of the problem was that we always compute
- time in usec's, but we ask users to input sec's. This means we
- need to convert to usec's before using those values.
- [Ryan Bloom]
-
- *) The worker MPM now handles shutdown and restart requests. It
- definitely isn't perfect, but we do stop the servers correctly.
- The biggest problem right now is that SIGHUP causes the server to
- just die. [Ryan Bloom]
-
-Changes with Apache 2.0.23
-
- *) Use the prefork MPM by default on Unix. [various]
-
- *) Added a systray icon monitor application for Win32.
- [Mladen Turk <mturk mappingsoft.com>]
-
- *) mod_rewrite: Fix the line ending on some non-Unix systems for
- messages written to the rewrite log.
- [Richard Labennett <rlabenn us.ibm.com>]
-
- *) All mod_autoindex query parsing is now quietly quashed with the
- IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
- still drops the column sort <a href>'s for the column headers, but
- IgnoreClient is required to ignore these Query options entirely.
- [William Rowe]
-
- *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
- to allow the client to select plain, FancyIndexing or HTMLTable
- formatting, V=[0|1] to inhibit or enable version sorting, and
- P=pattern to return only specific files. The old Query Arguments
- were reorganized as C=f for sorting column 'f' (same N, D, S, or M
- as before), and O=A|D for ordering ascending or descending.
- [William Rowe]
-
- *) Fixed an error in mod_include's directive parsing routines which
- caused #if, #elif, and #else expressions containing backslashes
- to be improperly evaluated. [Cliff Woolley]
-
- *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
- drop the icon column, SuppressRules to drop the <hr> elements,
- and HTMLTable to create rudimentary HTML table listings (implies
- FancyIndexing). [William Rowe]
-
- *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
- from Apache 1.3.15. This is needed for two reasons, first, given
- multiple machines within a server farm, ETags and Last-Modified
- stamps won't correspond from machine to machine, and second, many
- Unixes don't capture changes to the date or time stamp of existing
- files, since these don't modify the dirent itself. [William Rowe]
-
- *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
- and DirectoryWidth options from Apache 1.3.10.
- [William Rowe, Ken Coar]
-
- *) Eliminated FancyIndexing directive, deprecated early in Apache
- 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
-
- *) mod_autoindex now excludes any file names that would result in
- an error, other than a success or redirect. Also optimized
- the parent directory, always included except in the URI '/'.
- [William Rowe]
-
- *) Refactored mod_negotiation and mod_mime to help mod_dir accept
- negotiated index pages, and prevent the server from defaulting
- to an autoindex of the directory. mod_negotiation will now die
- with a 500 Internal Error if it could match some filenames
- (e.g. for mod_dir) but none can be served. mod_negotation now
- refuses to serve any file with an extention that mod_mime doesn't
- recognize, and wasn't part of the request. [William Rowe]
-
- *) Eliminate mod_cgi's handling of .exe files without the .exe file
- extension. This is already handled by multiviews, if the admin
- wishes to AddHandler .exe or define a content type handler and
- associate .exe files with that content type. Multiviews must be
- enabled to allow these to be served. [William Rowe]
-
- *) Speed up the server's response to a spike in incoming workload
- or restarts by assigning empty scoreboard slots to new processes
- when they are available. [Greg Ames]
-
- *) Add a handler to mod_includes.c. This handler is designed to
- implement the XbitHack directive. This can't be done with a
- fixup, because we need to check the content-type, which is
- only available in the handler phase. [Ryan Bloom]
-
- *) Make the includes filter check return codes from filters lower in
- the filter chain. If a lower level filter returns an error, then
- the request needs to stop immediately. This allows mod_include to
- stop parsing data once a lower filter recognizes an error.
- [Ryan Bloom]
-
- *) Add the ability to extend the methods that Apache understands
- and have those methods <limit>able in the httpd.conf. It uses
- the same bit mask/shifted offset as the original HTTP methods
- such as M_GET or M_POST, but expands the total bits from an int to
- an ap_int64_t to handle more bits for new request methods than
- an int provides. [Cody Sherr <csherr covalent.net>]
-
- *) Fix broken mod_mime behavior in merging its arguments. Possible
- cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
-
- *) Solve many mod_ssl porting issues (too many to detail) with
- help from the whole team, but most notably [Ralf S. Engelschall,
- Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
- Doug MacEachern, William Rowe, Cliff Woolley]
-
- *) More stall fixes for the threaded & worker mpm's.
- Make mod_status output more accurate. Don't
- count workers in processes which aren't actively
- serving requests. [Greg Ames]
-
- *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
-
- *) Add a single listener/multiple worker MPM. This MPM is
- definately not fully correct, but it allows us to solve many
- of the problems that exist in the threaded MPM. This is a
- modified version of the threaded MPM. [Ryan Bloom]
-
- *) Improve content generation throughout Apache, providing closer
- compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
- Transitional specifications. [William Rowe]
-
-Changes with Apache 2.0.22
-
- *) Fix a problem where the threaded MPM stalls after restarts or
- segfaults. Also prevent multiple active processes from using
- the same scoreboard slot. [Greg Ames]
-
- *) Apache/Win32 now fills in the service description with Apache's
- server version string, including loaded and advertised modules.
- [William Rowe]
-
- *) Improved support for the Win32 build, to recover gracefully from
- missing apr or apr-util directories or the awk interpreter,
- create the proper cgi-bin examples, including a test-cgi.bat, and
- fix the perl shebang line for printenv.pl, when installing from
- the build environment. [William Rowe]
-
- *) Fix a segfault in threaded.c caused by passing uninitialized
- apr_thread_t * to apr_thread_join(). [Jeff Trawick]
-
- *) Use new APR number conversion functions to reduce CPU consumption
- when setting the content length, and in mod_log_config.
- [Brian Pane]
-
- *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
- where HEAD response headers were being repeated twice for
- files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
- problem in the http_header filter was exposed by the recent rewrite
- of the content_length filter. [Taketo Kabe, Bill Stoddard]
-
- *) Fix seg faults in mod_status with ExtendedStatus enabled, after
- restarts. A garbage pointer to a vhost's server_rec from the
- previous generation was being left around under certain
- conditions. [Greg Ames]
-
- *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
- used to appear as '(none', without the closing paren.
- [Günter Knauf <eflash gmx.net>]
-
- *) Improve the exports generating awk script. In the past, we had
- work around problems in the awk script by avoiding some #if and
- #ifdefs. This has bitten us many times in generating the exports.c
- file. This improvement allows corrects the header file parsing.
- [Sander Striker <striker apache.org>]
-
-Changes with Apache 2.0.21
-
- *) Resolve the Win32 htpasswd bug, where a file that existed would be
- overwritten, regardless of the -c flag.
- [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
-
- *) Introduce connection sub-pools into ab. Truncating the lifetime
- of these allocations means that ab no longer perpetually grows
- its working set, running out of memory on large request attempts.
- [William Rowe]
-
- *) Make scoreboard creation a hook. This allows management
- modules to have access to the scoreboard at the time that it is
- created, and at every restart request.
- [Cody Sherr <csherr covalent.net>]
-
- *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
- added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
- daemon index actually used in the scoreboard. I also
- updated the pertinent calls. [Paul J. Reder]
-
- *) Win32: Prevent listening sockets from being inherited by
- the Apache child process, CGI scripts, rotatelog process
- etc. If the Apache child process segfaults, any processes
- that the child started are not reaped. Prior to this fix,
- these processes inherited the listening sockets which sometimes
- prevented the restarted Apache child process from accepting
- connections (ie, the server would hang).
- [Bill Stoddard]
-
- *) Provide vhost and request strings when ExtendedStatus is on.
- [Greg Ames]
-
- *) Fix some issues with the pod and prefork: check the pod *after*
- processing a connection so that a server processing a time-
- consuming request bails out as soon as practical; when the
- parent process wakes up a server process via connect(), use an
- APR timeout on the connect() so that we don't hang for a long
- time if there aren't server processes around to do accept().
- [Jeff Trawick, Greg Ames]
-
- *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
- spends a lot of time in apr_table_get calls. Using the default
- httpd.conf, the tables for languages and charsets are somewhat
- large, so the time spent scanning them on each request is
- significant. Replacing the tables with hash tables provides
- a nice speedup. [Brian Pane <bpane pacbell.net>]
-
- *) Add two functions to allow modules to access random parts of the
- scoreboard. This allows modules compiled for one MPM to access the
- scoreboard, even if it the server was compiled for another MPM.
- [Harrie Hazewinkel <harrie covalent.net>]
-
-Changes with Apache 2.0.20
-
- *) Fix problem in content-length filter where the filter would
- buffer all the output from a CGI before sending any bytes
- down the filter stack to the network. This problem would cause
- significant memory consumption if the CGIs generated
- lots of bytes. [Bill Stoddard]
-
- *) Get non-blocking CGI pipe reads working with the bucket brigades.
- [Bill Stoddard]
-
- *) Fix seg fault on Windows when serving files cached with mod_file_cache.
- [Bill Stoddard]
-
- *) Fix a bug in the threaded MPM that would cause it to kill off all
- workers immediately after starting if the number of workers started
- was above a certain threshold. [Ryan Bloom, Bill Stoddard]
-
-Changes with Apache 2.0.19
-
- *) Fix problem with threaded MPM. The problem was that if each child
- process was busy serving a single long-lived request and the server
- was sent a graceful restart signal, the server would stop serving
- requests. This would happen because each child process would wait to
- die until the last thread was done, and the parent wouldn't spawn any
- new children until a process died. Now, the parent looks at the fact
- that the children are dying gracefully, and starts new children.
- Those new children only start enough threads to compliment the number
- of threads in the other child process that shares the same spot in
- the scoreboard. In this way, we make sure to never go over
- MaxClients. [Ryan Bloom]
-
- *) modified mod_negotiation and mod_autoindex to speed up by almost a
- factor of two on apr_dir_read()-enhanced platforms, such as Win32
- and OS2, by calling ap_sub_request_lookup_dirent() with the results
- already provided by apr_dir_read(). [William Rowe]
-
- *) mod_file_cache is now more robust to filtering and serves requests
- slightly more efficiently. [Cliff Woolley]
-
- *) Fix problem handling FLUSH bucket in the chunked encoding filter.
- Module was calling ap_rwrite() followed by ap_rflush() but the
- served content was not being displayed in the browser. Inspection
- of the output stream revealed that the first data chunk was
- missing the trailing CRLF required by the RFC. [Bill Stoddard]
-
- *) apxs no longer generates ap_send_http_header() in the example handler
-
- *) Fix an ab problem which could cause a divide-by-zero exception
- with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
- [Ian Holsman <ianh cnet.com>]
-
- *) Solve case-insensitive platforms' confusion about negotiated
- filenames, allowing files of differnt case to match in choosing
- the document to serve. [William Rowe]
-
- *) Fix brokenness when ThreadsPerChild is higher than the built-in
- limit. We left ap_threads_per_child at the higher value which
- led to segfaults when doing certain scoreboard operations.
- [Jeff Trawick]
-
- *) Fix seg faults and/or missing output from mod_include. The
- default_handler was using the subrequest pool for files and
- MMAPs, even though the associated APR structures typically
- live longer than the subrequest. [Greg Ames]
-
- *) Extend mod_setenvif to support specifying regular expressions
- on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
- Example: SetEnvIf ^TS* [a-z].* HAVE_TS
- will cause HAVE_TS to be set if any of the request headers begins
- with "TS" and has a value that begins with any character in the
- set [a-z]. [Bill Stoddard]
-
- *) httpd children now re-bind themselves to a random CPU on
- multiprocessor systems on AIX via bindprocessor() in 2.0.
- [Victor J. Orlikowski]
-
- *) Fix htdigest. It would go into a loop in getline when adding
- a second user. [Bill Stoddard]
-
- *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
-
- *) Automatically generate httpd.exp for AIX.
- DSOs now work again on AIX in 2.0
- [Victor J. Orlikowski]
-
- *) Add a new request hook, error_log. This phase allows modules
- to act on the error log string _after_ it has been written
- to the error log. The goal for this hook is to allow monitoring
- modules to send the error string to the monitoring agent.
- [Ryan Bloom]
-
- *) Modify mod_echo to make it use filters for input and output.
- [Ryan Morgan <rmorgan covalent.net>]
-
- *) Extend mod_headers to support conditional driven Header
- add, append and set. Use SetEnvIf to set an envar and conditionally
- add/append/set headers based on this envar thusly:
-
- SetEnvIf TSMyHeader value HAVE_TSMyHeader
- Header add MyHeader "%t %D" env=HAVE_TSMyHeader
-
- If the request contains header "TSMyHeader: value" then header
- MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
- [Bill Stoddard]
-
- *) Extend mod_headers to support using format specifiers on Header
- add, append and set header values. Two format specifiers are supported:
-
- %t - reports, in UTC microseconds since the epoch, when the
- request was received.
-
- %D - reports the time, in microseconds, between when the request was
- received and the response sent.
-
- Examples:
- Header add MyHeader "This request served in %D microseconds. %t"
-
- results in a header being added to the response that looks like this:
-
- MyHeader: This request served in D=5438 microseconds. t=991424704447256
-
- [Bill Stoddard]
-
- *) Fix reset_filter(). We need to be careful how we remove filters.
- If we set r->output_filters to NULL, we also have to reset the
- connection's filters. [John Sterling]
-
- *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
-
- *) Add a check to ap_die() to make sure the filter stack is sane and
- contains the correct basic filters when an error occurs. This fixes
- a problem where headers are not being sent on error. [John Sterling]
-
- *) New Header directive 'echo' option. "Header echo regex" will
- cause any headers received on the request that match regex to be
- echoed to (included in) the response headers.
- [Bill Stoddard]
-
- *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
- This prevented the inclusion of apr_compat.h. PR #7773
- [Oleg Broytmann <phd phd.pp.ru>]
-
- *) Moved util_uri to the apr-util library. This required a bunch of
- apr_name changes for the uri utility functions. [Justin Erenkrantz]
-
- *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
- insert_filter phase so that other filters are not bypassed by default.
- [Graham Leggett]
-
- *) Reimplement mod_headers as an output filter. mod_headers can now
- add custom headers to inbound requests using the RequestHeader directive
- and to responses using the same old Header directive. [Graham Leggett]
-
-Changes with Apache 2.0.18
-
- *) Fix command-line processing so that if a bad argument is specified
- Apache will exit. [Jeff Trawick]
-
- *) Change the make targets and rules to be consistent in all of the
- Apache-owned source trees. [Roy Fielding]
-
- *) Fix processing of the TRACE method. Previously we passed bogus
- parms to form_header_field() and it overlaid some vhost structures,
- resulting in a segfault in check_hostalias().
- [Greg Ames, Jeff Trawick]
-
- *) Win32: Add support for reliable piped logs. If the logging process
- goes down, Apache will automatically restart it. This function has
- been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
- [Bill Stoddard]
-
- *) Do not start piped log processes during the config file
- preflight. This change also circumvents a problem on
- Windows where the rotatelog processes created during preflight
- was not getting cleaned up properly.
- [Bill Stoddard]
-
- *) add "Request Phase Participation" info to mod_info
- [Doug MacEachern]
-
- *) Make first phase changes to the scoreboard data structures in
- preparation for the rewriting of the scoreboard per my posted
- design notes. [Paul J. Reder]
-
- *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
- and apr-util, allow it to be overridden by the configure command-line
- (default="--silent") and introduce LT_LDFLAGS to replace what we were
- formerly abusing as LTFLAGS. [Roy Fielding]
-
- *) Clean up the reporting of incorrect closing container tags.
- [Barrie Slaymaker <barries slaysys.com>]
-
- *) Simplify the configure process by moving all libtool stuff to APR
- and moving hints.m4 inline. [Roy Fielding]
-
- *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
- of functions used by mod_proxy for export in the DLL
- [Ian Holsman <IanH cnet.com>]
-
- *) Prevent a hang when a cgi handled by mod_cgid tries to read a
- request body from its stdin but no reqest body is being written to
- the cgi. [Jeff Trawick]
-
- *) mod_log_config: %c connection status incorrectly logged
- as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
- [Bill Stoddard]
-
- *) Get mod_cern_meta working under Windows
- [Bill Stoddard]
-
- *) Create Files, and thus MMAPs, out of the request pool, not the
- connection pool. This solves a small resource leak that had us
- not closing files until a connection was closed. In order to do
- this, at the end of the core_output_filter, we loop through the
- brigade and convert any data we have into a single HEAP bucket
- that we know will survive clearing the request_rec.
- [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
- Cliff Woolley]
-
- *) Completely revamp configure so that it preserves the standard make
- variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
- the configure additions to EXTRA_* variables. Also, allow the user
- to specify NOTEST_* values for all of the above, which eliminates the
- need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
- of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
- avoid pointless duplications. Fix the order in which flags are given
- on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
- AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
- Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
- Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
-
- *) Get mod_tls to compile/work better on Windows. PR #7612
- [Bernhard Schrenk <b.schrenk improx.com>]
-
- *) Fix shutdown/restart hangs in the threaded MPM.
- [Jeff Trawick, Greg Ames, Ryan Bloom]
-
- *) Removed the keptalive boolean from conn_rec because it is now only
- used by a single routine and can be replaced by a local variable.
- [Greg Stein, Ryan Bloom, Roy Fielding]
-
- *) Patch prefork to put enough of the signal processing back in so that
- signals are all handled properly now. The previous patch fixed the
- deadlock race condition, but broke the user directed signal handling.
- This fixes it to work the way it did before my previous prefork patch
- (primarily, SIGTERM is now working).
-
- *) Change how input filters decide how much data is returned to the
- higher filter. We used to use a field in the conn_rec, with this
- change, we use an argument to ap_get_brigade to determine how much
- data is retrieved. [Ryan Bloom]
-
- *) Fix seg fault at start-up introduced by Ryan's change to enable
- modules to specify their own logging tags. mod_log_config
- registers an optional function, ap_register_log_handler().
- ap_register_log_handler() was being called by http_core before
- the directive hash table was created. This patch creates the
- directive hash table before ap_register_log_handler() is
- registered as an optional function.
- [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
-
- *) Add ap_set_int_slot() function
- [John K. Sterling <sterling covalent.net>]
-
- *) Under certain circumstances, Apache did not supply the
- right response headers when requiring authentication.
- [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
- (This is a port of the change that went into Apache 1.3.19.)
-
- *) Allow modules to specify their own logging tags. This basically
- allows a module to tell mod_log_config that when %x is encountered
- a specific function should be called. Currently, x can be any single
- character. It may be more useful to make this a string at some point.
- [Ryan Bloom]
-
-Changes with Apache 2.0.17
-
- *) If a higher-level filter handles the byterange aspects of a
- request, then the byterange filter should not try to redo the
- work. The most common case of this happening, is a byterange
- request going through the proxy, and the origin server handles
- the byterange request. The proxy should ignore it.
- [Graham Leggett <minfrin sharp.fm>]
-
- *) Changed the threaded mpm to have child_main join to each of the
- worker threads to make sure the kids are all gone before child_main
- exits after a signal (cleanup from perform_idle_server_maintenance).
- This is an extension of Ryans recent commit to make the child_main
- the signal thread.
-
- *) Add more options to the ap_mpm_query function. This also allows MPMs to
- report if their threads are dynamic or static. Finally, this also
- implements a new API, ap_show_mpm, which returns the MPM that was
- required into the core. [Harrie Hazewinkel <harrie covalent.net>]
-
- *) Do not install the binaries from the support directory twice.
- [jun-ichiro hagino <itojun iijlab.net>]
-
- *) The ap_f* functions should flush data to the filter that is passed
- in, not the filter after the one passed in.
- [Ryan Morgan <rmorgan covalent.net>]
-
- *) Make ab work again by changing its native types to apr types and formats.
- [Justin Erenkrantz <jerenkrantz ebuilt.com>]
-
- *) Move the byterange filter and all of the supporting functions back
- to the HTTP module. The byterange filter turned out to be very
- HTTP specific, and it belongs in the HTTP module. [Greg Stein]
-
- *) Make clean, distclean, and extraclean consistently according to the
- Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
-
- *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
- This may have been causing problems stopping processes in the threaded
- mpm's. [Greg Ames]
-
- *) Fix content-length in mod_negotiation to a long int representation.
- [William Rowe]
-
- *) Remove BindAddress from the default config file.
- [<giles nemeton.com.au>]
-
- *) Allow module authors to add a module to their Apache build using
- --with-module, without re-running buildconf. The syntax is:
- --with-module=module_type:/path/to/module.c
- The configure script will copy the module.c file to
- modules/module_type, and it will be added to the relevant Makefiles.
- currently, this only works for static modules. [Ryan Bloom]
-
- *) Changes required to make prefork clean up idle children properly.
- There was a window during which a starting worker deadlocks when
- an idle cleanup arrives before it completes init. Apache then keeps
- trying to cleanup the same deadlocked worker forever (until higher
- pids come along, but it still will never reduce below the deadlocked
- pid). Thus the number of children would not reduce to the correct
- idle level. [Paul J. Reder]
-
-Changes with Apache 2.0.16
-
- *) Change the default installation directory to /usr/local/apache2,
- as now defined by the "Apache" layout in config.layout. [Marc Slemko]
-
- *) OS/2: Added support for building loadable modules as OS/2 DLLs.
- [Brian Havard]
-
- *) Get MaxRequestsPerChild working with the Windows MPM.
- [Bill Stoddard]
-
- *) Make generic hooks to work, with mod_generic_hook_import/export
- experimental modules. [Ben Laurie, Will Rowe]
-
- *) Fix segfaults for configuration file syntax errors such as
- "<Directory>" followed by "</Directory" and
- "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
-
- *) Cleanup the --enable-layout option of configure. This makes
- us use a consistent location for the config.layout file, and it
- makes configure more portable.
- [jun-ichiro hagino <itojun iijlab.net>]
-
- *) Changes to 'ab'; fixed int overrun's, added statistics, output in
- csv/gnuplot format, rudimentary ssl support and various other tweaks
- to make results more true to what is measured. The upshot of this it
- turns out that 'ab' has often underreported the true performance of
- apache. Often by a order of magnitude :-) See talk/paper of Sander
- Temme at April ApacheCon 2001 for details.
- [Dirk-Willem van Gulik]
-
- *) Clean up mod_cgid's temporary request pool. Besides fixing a
- storage leak this ensures that some unnecessary pipes are closed.
- [Jeff Trawick]
-
- *) Performance: Add quick_handler hook. This hook is called at the
- very beginning of the request processing before location_walk,
- translate_name, etc. This hook is useful for URI keyed content
- caches like Mike Abbott's Quick Shortcut Cache.
- [Bill Stoddard]
-
- *) top_module global variable renamed to ap_top_module [Perl]
-
- *) Move ap_set_last_modified to the core. This is a potentially
- controversial change, because this is kind of HTTP specific. However
- many protocols should be able to take advantage of this kind of
- information. I expect that headers will need one more layer of
- indirection for multi-protocol work, but this is a small step in
- the right direction. [Ryan Bloom]
-
- *) Enable mod_status by default. This matches what Apache 1.3 does.
- [Ed Korthof]
-
- *) Add a ScriptSock directive to the default config file. This is
- only enabled when mod_cgid is used.
- [Taketo Kabe <kabe sra-tohoku.co.jp>]
-
-Changes with Apache 2.0.15
-
- *) Untangled the buildconf script and eliminated the need for build's
- aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
- libtool muck that is now under srclib/apr/build. [Roy Fielding]
-
- *) Win32: Don't accept more connections than we have worker threads
- to handle.
- [Bill Stoddard]
-
- *) Fix bug in the Unix threaded.c MPM that allowed child processes
- to fork() new child processes.
- [Bill Stoddard]
-
- *) SECURITY: Fix a major security problem with double-reverse lookup
- checking. Previously, a client connecting over IPv4 would not be
- matched properly when the server had an IPv6 listening socket.
- PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
-
- *) Change the way the beos MPM handles polling to allow it to stop and
- restart. Problem was the sockets being polled were being reset by
- the select call, so once it had accepted a connection it was no
- longer listening on the UDP socket we use for shutdown instructions.
- APR needs to be altered, patch on it's way. [David Reid]
-
- *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
- on error exit from ap_getline(). Some other code got upset because
- the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
-
- *) Handle ap_discard_request_body() being called more than once.
- [Greg Ames, Jeff Trawick]
-
- *) Get rid of an inadvertent close of file descriptor 2 in
- mod_mime_magic. [Greg Ames, Jeff Trawick]
-
- *) Add a hook, create_request. This hook allows modules to modify
- a request while it is being created. This hook is called for all
- request_rec's, main request, sub request, and internal redirect.
- When this hook is called, the r->main, r->prev, r->next
- pointers have been set, so modules can determine what kind of
- request this is. [Ryan Bloom]
-
- *) Cleanup the build process a bit more. The Apache configure
- script no longer creates its own helper scripts, it just
- uses APR's.
- [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
-
- *) Stop the forced downgrade of the connection to HTTP/1.0 for
- proxy requests. [Graham Leggett]
-
- *) Avoid using sscanf to determine the HTTP protocol number in
- the common case because sscanf is a performance hog. From
- Mike Abbot's Accelerating Apache patch number 6.
- [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
-
- *) SECURITY: Fix a security exposure in mod_access. Previously when
- IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
- were not evaluated properly (PR #7407). Also, add the ability to
- specify IPv6 address strings with optional prefix length on Allow
- and Deny. [Jeff Trawick]
-
- *) Enhance rotatelogs so that a UTC offset can be specified, and
- the logfile name can be formatted using strftime(3). (Brought
- forward from 1.3.) [Ken Coar]
-
- *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
- DuplicateHandle on an IOCompletionPort (a practice which
- MS "discourages"). The new model does not rely on associating
- the completion port with the listening sockets, thus the
- completion port can be completely managed within the child
- process. A dedicated thread accepts connections off the network,
- then calls PostQueuedCompletionStatus() to wake up worker
- threads blocked on the completion port.
- [Bill Stoddard]
-
- *) Bring forward the --suexec-umask option which allows the
- builder to preset the umask for suexec processes. [Ken Coar]
-
- *) Add a -V flag to suexec, which causes it to display the
- compile-time settings with which it was built. (Only
- usable by root or the AP_HTTPD_USER username.) [Ken Coar]
-
- *) Mod_include should always unset the content-length if the file is
- going to be passed through send_parsed_content. There is no to
- determine if the content will change before actually scanning the
- entire content. It is far safer to just remove the C-L as long
- as we are scanning it. [Ryan Bloom]
-
- *) Make sure Apache sends WWW-Authenticate during a reverse proxy
- request and not Proxy-Authenticate.
- [Graham Leggett <minfrin sharp.fm>]
-
-Changes with Apache 2.0.14
-
- *) Fix content-length computation. We ONLY compute a content-length if
- We are not in a 1.1 request and we cannot chunk, and this is a keepalive
- or we already have all the data. [Ryan Bloom]
-
- *) Report unbounded containers in the config file. Previously, a typo
- in the </container> directive could result in the rest of the config
- file being silently ignored, with undesired defaults used.
- [Jeff Trawick]
-
- *) Make the old_write filter use the ap_f* functions for the buffering.
- [Ryan Bloom]
-
- *) Move more code from the http module into the core server. This
- is core code, basically the default handler, the default input
- and output filters, and all of the core configuration directives.
- All of this code is required in order for the server to work, with or
- without HTTP. The server is closer to working without the HTTP
- module, although there is still more to do. [Ryan Bloom]
-
- *) Fix a number of SGI compile warnings throughout the server. Fix some
- bad parameters to apr_bucket_read(). Fix a bad statement in
- ap_method_in_list(). For the mod_rewrite cache use apr_time_t
- consistently; we were mixing apr_time_t and time_t in invalid ways
- before. In load_file(), call apr_dso_error() instead of
- apr_strerror() so that we get a more specific string on some platforms.
- PR #6980 [Jeff Trawick]
-
- *) Allow modules to query the MPM about it's execution profile. This
- query API can and should be extended in the future, but for now,
- max_daemons, and threading or forking is a very good start.
- [Jon Travis <jtravis covalent.net>]
-
- *) Modify mod_include to send blocks of data no larger than 9k.
- Without this, mod_include will wait until the whole file is parsed,
- or the first tag is found to send any data to the client.
- [Paul J. Reder <rederpj raleigh.ibm.com>]
-
- *) Fix mod_info, so that <Directory> and <Location> directives are
- not displayed twice when displaying the current configuration.
- [Ryan Morgan <rmorgan covalent.net>]
-
- *) Add config directives to override DEFAULT_ERROR_MSG and
- DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
- [Dan Rench <drench xnet.com>]
-
- *) Get mod_info building and loading on Win32. [William Rowe]
-
- *) Begin to move protocol independant functions out of mod_http. The goal
- is to have only functions that are HTTP specific in the http directory.
- [Ryan Bloom]
-
-Changes with Apache 2.0.13
-
- *) Don't assume that there will always be multiple calls to the byterange
- filter. It is possible that we will need to do byteranges with only
- one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
-
- *) Move the error_bucket definition from the http module to the
- core server. Every protocol will need this ability, not just
- HTTP. [Ryan Bloom]
-
-Changes with Apache 2.0.12
-
- *) Modify mod_file_cache to save pre-formatted strings for
- content-length and last-modified headers for performance.
- [Mike Abbot <mja trudge.engr.sgi.com>]
-
- *) Namespace protect IOBUFSIZ since it is exposed in the API.
- [Jon Travis <jtravis covalent.net>]
-
- *) Use "Basic" authentication instead of "basic" in ab, as the spec
- says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
-
- *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
- without ever filling it out. This fixes PR 7271.
- [Taketo Kabe <kabe sra-tohoku.co.jp> and
- Cliff Woolley <cliffwoolley yahoo.com>]
-
- *) Add a couple of GCC attribute tags to printf style functions.
- [Jon Travis <jtravis covalent.net>]
-
- *) Add the correct language tag for interoperation with the Taiwanese
- versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
-
- *) Migrate the perchild MPM to use the new apr signal child, and
- APR thread functions. [Ryan Bloom]
-
- *) Close one copy of the CGI's stdout before creating the new process.
- The CGI will still have stdout, because we have already dup'ed it.
- This keeps Apache from waiting forever to send the results of a CGI
- process that has forked a long-lived child process.
- [Taketo Kabe <kabe sra-tohoku.co.jp>]
-
- *) Remove the rest of the pthreads functions from the threaded MPM.
- This requires the APR support for a signal thread that was just
- added. [Ryan Bloom]
-
- *) Make mod_dir use a fixup for sending a redirect to the browser.
- Before this, we were using a handler, which doesn't make much
- sense, because the handler wasn't generating any data, it would
- either return a redirect error code, or DECLINED. This fits the
- current hooks better. [Ryan Morgan <rmorgan covalent.net>]
-
- *) Make the threaded MPM use APR threads instead of pthreads.
- [Ryan Bloom]
-
- *) Get mod_tls to the point where it actually appears to work in all cases.
- [Ben Laurie]
-
- *) implement --enable-modules and --enable-mods-shared for "all" and
- "most". [Greg Stein]
-
- *) Move the threaded MPM to use APR locks instead of pthread locks.
- [Ryan Bloom]
-
- *) Rename mpmt_pthread to threaded. This is more in line with the
- fact that mpmt_pthread shouldn't be using pthreads directly, and
- it is a smaller name that doesn't tie into anything.
- [Ryan Bloom]
-
- *) Rename the module structures so that the exported symbol matches
- the file name, and it is easier to automate the installation
- process (generating LoadModule directives from the module filenames).
- [Martin Kraemer]
-
- *) Remove the coalesce filter. With the ap_f* functions, this filter
- is no longer needed. [Ryan Bloom]
-
-Changes with Apache 2.0.11
-
- *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
- added feature of allowing a uid/gid per child process. If no
- uid/gid is specified, then Perchild behaves exactly like dexter.
- [Ryan Bloom]
-
- *) Get perchild building again. [Ryan Bloom]
-
- *) Don't disable threads just because we are using the prefork MPM.
- If somebody wants to compile without threads, they must now add
- --disable-threads to the configure command line. [Ryan Bloom]
-
- *) Begin to move the calls to update_child_status into common code, so
- that each individual MPM does not need to update the scoreboard itself.
- [Ryan Bloom]
-
- *) Allow mod_tls to compile under Unix boxes where openssl has been
- installed to the system include files.
- [Gomez Henri <new-httpd slib.fr>]
-
- *) Cleanup the mod_tls configure process. This should remove any need
- to hand-edit any files. We require OpenSSL 0.9.6 or later, but
- configure doesn't check that yet. [Ryan Bloom]
-
- *) Add a very early prototype of SSL support (in mod_tls.c). It is
- vital that you read modules/tls/README before attempting to build
- it. [Ben Laurie]
-
- *) Fix a potential seg fault on all platforms. David Reid fixed this
- on BEOS, but the problem could happen anywhere, so we don't want
- to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
-
- *) Add new LogFormat directive, %D, to log time it takes to serve a
- request in microseconds. [Bill Stoddard]
-
- *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
- SetOutputFilter. This corresponds nicely with the other Set
- directives, which operate on containers while the Add* directives
- tend to work directly on extensions. [Ryan Bloom]
-
- *) Cleanup the header handling a bit. This uses the apr_brigade_*
- functions for the buffering so that we don't need to compute
- the length of the headers before we actually create the header
- buffer. [Ryan Bloom]
-
- *) Allow filters to buffer data using the ap_f* functions. These have
- become macros that resolve directly to apr_brigade_*.
- [Ryan Bloom]
-
- *) Get the Unix MPM's to do a graceful restart again. If we are going
- to register a cleanup with ap_cleanup_scoreboard, then we have to
- kill the cleanup with the same function, and that function can't be
- static. [Ryan Bloom]
-
- *) Install all required header files. Without these, it was not
- possible to compile some modules outside of the server.
- [Ryan Bloom]
-
- *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
- forward from 1.3 to 2.0, we missed a single line, which broke regex
- aliases. [Ryan Bloom]
-
- *) We have a poor abstraction in the protocol. This is a temporary
- hack to fix the bug, but it will need to be fixed for real. If
- we find an error while sending out a custom error response, we back
- up to the first non-OK request and send the data. Then, when we send
- the EOS from finalize_request_protocol, we go to the last request,
- to ensure that we aren't sending an EOS to a request that has already
- received one. Because the data is sent on a different request than
- the EOS, the error text never gets sent down the filter stack. This
- fixes the problem by finding the last request, and sending the data
- with that request. [Ryan Bloom]
-
- *) Make the server status page show the correct restart time, and
- thus the proper uptime. [Ryan Bloom]
-
- *) Move the CGI creation logic from mod_include to mod_cgi(d). This
- should reduce the amount of duplicate code that is required to
- create CGI processes.
- [Paul J. Reder <rederpj raleigh.ibm.com>]
-
- *) ap_new_connection() closes the socket and returns NULL if a socket
- call fails. Usually this is due to a connection which has been
- reset. [Jeff Trawick]
-
- *) Move the Apache version information out of httpd.h and into release.h.
- This is in preparation for the first tag with the new tag and release
- system. [Ryan Bloom]
-
- *) Begin restructuring scoreboard code to enable adding back in
- the ability to use IPC other than shared memory.
- Get mod_status working on Windows again. [Bill Stoddard]
-
- *) Make mod_status work with 2.0. This will work for prefork,
- mpmt_pthread, and dexter. [Ryan Bloom]
-
- *) Correct a typo in httpd.conf.

-
- *) Really fix mod_rewrite map lookups this time. [Tony Finch]

- *) Get the correct IP address if ServerName isn't set and we can't
- find a fully-qualified domain name at startup.
- PR#7170 [Danek Duvall <dduvall eng.sun.com>]
-
- *) Make mod_cgid work with SuExec. [Ryan Bloom]
-
- *) Adopt apr user/group name features for mod_rewrite. Eliminates some
- 'extra' stat's for user/group since they should never occur, and now
- resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
- volumes. [William Rowe]
-
- *) Adopt apr features to simplify mod_includes. This changes the
- behavior of the USER_NAME variable, unknown uid's are now reported
- as USER_NAME="<unknown>" rather than the old user#000 result.
- WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
-
- *) Adopt apr features for simplifing mod_userdir, and accept the new
- Win32/OS2 exceptions without hiccuping. [William Rowe]
-
- *) Replace configure --with-optim option by using and saving the
- environment variable OPTIM instead. This is needed because configure
- options do not support multiple flags separated by spaces.
- [Roy Fielding]
-
- *) Fix some byterange handling. If we get a byte range that looks like
- "-999999" where that is past the end of the file, we should return
- a PARTIAL CONTENT status code, and return the whole file as one big
- byterange. This matches the 1.3 handling now. [Ryan Bloom]
-
- *) Make the error bucket a real meta-data bucket. This means that the
- bucket length is 0, and a read returns NULL data. If one of these
- buckets is passed down after the headers are sent, this data will
- just be ignored. [Greg Stein]
-
- *) The prefork MPM wasn't killing child processes correctly if a restart
- signal was received while the process was serving a request. The child
- process would become the equivalent of a second parent process. If
- we break out of the accept loop, then we need to do die after cleaning
- up after ourselves. [Ryan Bloom]
-
- *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
- restarts. [Ryan Bloom]
-
- *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
- the most optimal APR_FINFO_wanted bits. This spares Win32 from
- performing very expensive owner, group and permission lookups
- and allows the server to function until these apr_finfo_t fields
- are implemented under Win32. [William Rowe]
-
- *) Support for typedsafe optional functions - that is functions exported by
- optional modules, which, therefore, may or may not be present, depending
- on configuration. See the experimental modules mod_optional_fn_{ex,im}port
- for sample code. [Ben Laurie]
-
- *) filters can now report an HTTP error to the server. This is done
- by sending a brigade where the first bucket is an error_bucket.
- This bucket is a simple bucket that stores an HTTP error and
- a string. Currently the string is not used, but it may be needed
- to output an error log. The http_header_filter will find this
- bucket, and output the error text, and then return
- AP_FILTER_ERROR, which informs the server that the error web page
- has already been sent. [Ryan Bloom]
-
- *) If we get an error, then we should remove all filters except for
- those critical to serving a web page. This fixes a bug, where
- error pages were going through the byterange filter, even though
- that made no sense. [Ryan Bloom]
-
- *) Relax the syntax checking of Host: headers in order to support
- iDNS. PR#6635 [Tony Finch]
-
- *) Cleanup the byterange filter to use the apr_brigade_partition
- and apr_bucket_copy functions. This removes a lot of very messy
- code, and hopefully makes this filter more stable.
- [Ryan Bloom]
-
- *) Remove AddModule and ClearModuleList directives. Both of these
- directives were used to ensure that modules could be enabled
- in the correct order. That requirement is now gone, because
- we use hooks to ensure that modules are in the correct order.
- [Ryan Bloom]
-
- *) When SuExec is specified, we need to add it to the list of
- targets to be built. If we don't, then any changes to the
- configuration won't affect SuExec, unless 'make suexec' is
- specifically run. [Ryan Bloom]
-
- *) Cleaned out open_file from mod_file_cache, as apr now accepts
- the APR_XTHREAD argument to open a file for consumption by
- parallel threads on win32. [William Rowe]
-
- *) Correct a bug in determining when we follow symlinks. The code
- expected a stat -1 result, not an apr_status_t positive error.
- Also check if the APR_FINFO_USER fields are valid before we
- follow the link. [William Rowe]
-
- *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
- mpm_common.c. These functions are only valid on some platforms,
- so they should not be in the main-line code. [Ryan Bloom]
-
- *) Remove ap_chdir_file(). This function is not thread-safe,
- and nobody is currently using it. [Ryan Bloom]
-
- *) Do not try to run make depend if there are no .c files in the
- current directory, doing so makes `make depend` fail.
- [Ryan Bloom]
-
- *) Update highperformance.conf to work with either prefork or
- pthreads mpms. [Greg Ames]
-
- *) Stop checking to see if this is a pipelined request if we know
- for a fact that it isn't. Basically, if r->connection->keepalive == 0.
- This keeps us from making an extra read call when serving a 1.0
- request. [Ryan Bloom and Greg Stein]
-
- *) Fix the handling of variable expansion look-ahead in mod_rewrite,
- i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
- more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
-
- *) Fix the RFC number mentioned when complaining about a missing
- Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
-
- *) Fix an endless loop in ab which occurred when ab was posting
- and the server dropped the connection unexpectedly.
- [Jeff Trawick]
-
- *) Fix a segfault while handling request bodies in ap_http_filter().
- This problem has been seen with mod_dav usage as well as with
- requests where the body was just being discarded. [Jeff Trawick]
-
- *) Some adjustment on the handling and automatic setting (via
- hints.m4) of various compilation flags (eg: CFLAGS). Also,
- add the capability to specify flags (NOTEST_CFLAGS and
- NOTEST_LDFLAGS) which are used to compile Apache, but
- not used during the configuration process. Useful for
- flags like "-Werror". [Jim Jagielski]
-
- *) Stop using environment variables to force debug mode or
- no detach. We now use the -D command line argument to
- specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
- [Greg Stein, Ryan Bloom]
-
- *) Change handlers to use hooks. [Ben Laurie]
-
- *) Stop returning copies of filenames from both apr_file_t and
- apr_dir_t. We pstrdup the filenames that we store in the
- actual structures, so we don't need to pstrdup the strings again.
- [Ryan Bloom]
-
- *) mod_cgi: Fix some problems where the wrong error value was being
- traced. [Jeff Trawick]
-
- *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
- [Jeff Trawick]
-
- *) Add generic hooks. [Ben Laurie]
-
- *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
-
- *) Fix a segfault caused by mod_ext_filter when the external filter
- program does not exist. [Jeff Trawick]
-
- *) Fix an output truncation error when on an HTTP >= 1.0 request an
- object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
- was served through mod_charset_lite (or anything else that would
- create a transient bucket in this size range). ap_bucket_make_heap()
- silently failed (fixed), transient_setaside() discovered it, but
- ap_save_brigade() ignored it (fixed). [Jeff Trawick]
-
- *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
- is that some browsers send extra lines at the end of POST requests, and
- we don't want to delay sending data back to the user just because the
- browser isn't well behaved. [Ryan Bloom]
-
- *) Get SuEXEC working again. We can't send absolute paths to suExec
- because it refuses to execute those programs. SuEXEC also wasn't
- always recognizing configuration changes made using the autoconf
- setup. [Ryan Bloom]
-
- *) Allow the buildconf process to find the config.m4 files in the correct
- order. Basically, we can now name config.m4 files as config\d\d.m4,
- and we will sort them correctly when inserting them into the build
- process. [Ryan Bloom]
-
- *) Get mod_cgid to use apr calls for creating the actual CGI process.
- This also allows mod_cgid to use ap_os_create_priviledged_process,
- thus allowing for SuExec execution from mod_cgid. Currently, we do
- not support everything that standard SuExec supports, but at least
- it works minimally now. [Ryan Bloom]
-
- *) Allow SuExec to be configured from the ./configure command line.
- [Ryan Bloom]
-
- *) Update some of the docs in README and INSTALL to reflect some of
- the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
-
- *) If we get EAGAIN returned from the call to apr_sendfile, then we
- need to call sendfile again. This gets us serving large files
- such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
-
- *) Get the support programs building cleanly again.
- [Cliff Woolley <cliffwoolley yahoo.com>]
-
- *) The Apache/Win32 Apache.exe and dll's now live in bin. The
- current directory logic now backs up over bin/ to determine the
- server root from the Apache.exe path.
-
- *) Apache/Win32 now follows the standard conventions of mod_foo.so
- loadable modules, dynamic libs are all named libfoo.dll, and the
- makefile.win populates the include, lib and libexec directories.
-
- *) Apache is now IPv6-capable. On systems where APR supports IPv6,
- Apache gets IPv6 listening sockets by default. Additionally, the
- Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
- numeric address strings (e.g., "Listen [fe80::1]:8080").
- [Jeff Trawick]
-
- *) Modify the install directory layout. Modules are now installed in
- modules/. Shared libraries should be installed in libraries/, but
- we don't have any of those on Unix yet. All install directories
- are modifyable at configure time. [Ryan Bloom]
-
- *) Install all header files in the same directory on Unix. [Ryan Bloom]
-
- *) Get the functions in server/linked into the server, regardless of
- which modules linked into the server. This uses the same hack
- for Apache that we use for APR and apr-util to ensure all of the
- necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
- was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
- the scripts a bit easier.
- [Ryan Bloom]
-
- *) Rework the RFC1413 handling to make it thread-safe, use a timeout
- on the query, and remove IPv4 dependencies. [Jeff Trawick]
-
- *) Get all of the auth modules to the point that they will install and
- be loadable into the server. Our new build/install mechanism expects
- that all modules will have a common name format. The auth modules
- didn't use that format, so we didn't install them properly.
- [Ryan Bloom]
-
- *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
- available. Use apr_getaddrinfo() instead. [Jeff Trawick]
-
- *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
-
- *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
- after the end of the response. [Ryan Bloom]
-
- *) Get byterange requests working with responses that do not have a
- content-length. Because of the way byterange requests work, we have to
- have all of the data before we can actually do the byterange, so we
- can compute the content-length in the byterange filter.
- [Ryan Bloom]
-
- *) Get exe CGI's working again on Windows.
- [Allan Edwards]
-
- *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
- they keep track of whether or not their post config hook has been
- called before. Instead of a static variable (which is replaced when
- the DSO is loaded a second time), use userdata in the process pool.
- [Jeff Trawick]
-
-Changes with Apache 2.0a9
-
- *) Win32 now requires perl to complete the final install step for users
- to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
- and installs the conf, htdocs and htdocs/manual directories.
- [William Rowe]
-
- *) Make mod_include use a hash table to associate directive tags with
- functions. This allows modules to implement their own SSI tags easily.
- The idea is simple enough, a module can insert it's own tag and function
- combination into a hash table provided by mod_include. While mod_include
- parses an SSI file, when it encounters a tag in the file, it does a
- hash lookup to find the function that implements that tag, and passes
- all of the relevant data to the function. That function is then
- responsible for processing the tag and handing the remaining data back
- to mod_include for further processing.
- [Paul J. Reder <rederpj raleigh.ibm.com>]
-
- *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
- fewer parameters: the local and remote socket addresses were removed
- from the parameter list because all required information is available
- via the APR socket. [Jeff Trawick]
-
- *) Distribution directory structure reorganized to reflect a
- normal source distribution with external install targets.
- [Roy Fielding]
-
- *) The MPMs that need multiple segments of shared memory now create
- two apr_shmem_t variables, one for each shared memory allocation.
- the problem is that we can't determine how much memory will be required
- for shared memory allocations once we try to allocate more than one
- variable. The MM code automatically aligns the shared memory allocations,
- so we end up needing to pad the amount of shared memory we want based
- on how many variables will be allocated out of the shared memory segment.
- It is just easier to create a second apr_shmem_t variable, and two
- shmem memory blocks.
- [Ryan Bloom]
-
- *) Cleanup the export list a bit. This creates a single unified list of
- functions exported by APR. The export list is generated at configure
- time, and that list is then used to generate the exports.c file.
- Because of the way the export list is generated, we only export those
- functions that are valid on the platform we are building on.
- [Ryan Bloom]
-
- *) Enable logging the cookie with mod_log_config
- [Sander van Zoest <sander covalent.net>]
-
- *) Fix a segfault in mod_info when it reaches the end of the configuration.
- [Jeff Trawick]
-
- *) Added lib/aputil/ as a placeholder for utility functions which are not
- specific to the Apache HTTP Server (but do not make sense with APR).
- The first utility is "apu_dbm": a set of functions to work with DBM
- files. This first version can be compiled for SDBM or GDBM databases.
- [Greg Stein]
-
- *) Complete re-write of mod_include. This makes mod_include a filter that
- uses buckets directly. This has now served the FAQ correctly.
- [Paul Reder <rederpj raleigh.ibm.com>]
-
- *) Allow modules to specify the first filter in a sub_request when
- making the sub_request. This keeps modules from having to change the
- output_filter immediately after creating the sub-request, and therefore
- skip the sub_req_output_filter. [Ryan Bloom]
-
- *) Update ab to accept URLs with IPv6 literal address strings (in the
- format described in RFC 2732), and to build Host header fields in
- the same format. This allows IPv6 literal address strings to be
- used with ab. This support has been tested against Apache 1.3 with
- the KAME patch, but Apache 2.0 does not yet work with this format
- of the Host header field. [Jeff Trawick]
-
- *) Accomodate an out-of-space condition in the piped logs and the
- rotatelogs.c code, and no longer churn log processes for this
- condition. [Victor J. Orlikowski]
-
- *) Add support for partial writes with apr_sendfile() to core_output_filter.
- [Greg Ames]
-
-Changes with Apache 2.0a8
-
- *) Add a directive to mod_mime so that filters can be associated with
- a given mime-type.
- [Ryan Bloom]
-
- *) Get multi-views working again. We were setting the path_info
- field incorrectly if we couldn't find the specified file.
- [Ryan Bloom]
-
- *) Fix 304 processing. The core should never try to send the headers
- down the filter stack. Always, just setup the table in the request
- record, and let the header filter convert it to data that is ready
- for the network.
- [Ryan Bloom]
-
- *) More fixes for the proxy. There are still bugs in the proxy code,
- but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
- successfully.
- [Ryan Bloom]
-
- *) Fix params for apr_getaddrinfo() call in connect proxy handler.
- [Chuck Murcko]
-
- *) APR: Add new apr_getopt_long function to handle long options.
- [B. W. Fitzpatrick <fitz red-bean.com>]
-
- *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
- Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
- hostname resolution/address string parsing and building
- apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
- of one of the apr_sockaddr_t structures for a socket. Change
- apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
-
- *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
- I have proxied pages with it, cleanup will commence soon.
- [Ryan Bloom]
-
- *) Make the proxy work with filters. This isn't perfect, because we
- aren't dealing with the headers properly. [Ryan Bloom]
-
- *) Do not send a content-length iff the C-L is 0 and this is a head
- request. [Ryan Bloom]
-
- *) Make cgi-bin work as a regular directory when using mod_vhost_alias
- with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
-
- *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
-
- *) Get the default_handler to stop trying to deal with HEAD requests.
- The idea is to let the content-length filter compute the C-L before
- we try to send the data. If we can get the C-L correctly, then we
- should send it in the HEAD response.
- [Ryan Bloom]
-
- *) The Header filter can now determine if a body should be sent based
- on r->header_only. The general idea of this is that if we delay
- deciding to send the body, then we might be able to compute the
- content-length correctly, which will help caching proxies to cache
- our data better. Any handler that doesn't want to try to compute
- the content-length can just send an EOS bucket without data and
- everything will just work.
- [Ryan Bloom]
-
- *) Add the referer to the error log if one is available.
- [Markus Gyger <mgyger itr.ch>]
-
- *) Mod_info.c has now been ported to Apache 2.0. As a part of this
- change, the root of the configuration tree has been exposed to modules
- as ap_conftree.
- [Ryan Morgan <rmorgan covalent.net>]
-
- *) Get the core_output_filter to use the bucket interface directly.
- This keeps us from calling the content-length filter multiple times
- for a simple static request.
- [Ryan Bloom]
-
- *) We are sending the content-type correctly now.
- [Ryan Bloom and Will Rowe]
-
- *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
- a bogus bytes-sent value when the only thing being sent was trailers
- and writev() returned an error (or EAGAIN). [Jeff Trawick]
-
- *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
- hints file to determine which platforms define
- SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
- [Ryan Bloom]
-
- *) APR: add apr_get_home_directory() [Jeff Trawick]
-
- *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
-
- *) Not all platforms have INADDR_NONE defined by default. Apache
- used to make this check and define INADDR_NONE if appropriate,
- but APR needs the check too, and I suspect other applications will
- as well. APR now defines APR_INADDR_NONE, which is always a valid
- value on all platforms.
- [Branko Čibej <brane xbc.nu>]
-
- *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
- [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
-
- *) Relax the syntax checking of Host: headers in order to support
- iDNS. PR#6635 [Tony Finch]
-
- *) When reading from file buckets we convert to an MMAP if it makes
- sense. This also simplifies the default handler because the
- default handler no longer needs to try to create MMAPs.
- [Ryan Bloom]
-
- *) BUFF has been removed from the main server. The BUFF code will remain
- in the code until it has been purged from the proxy module as well.
- [Ryan Bloom]
-
- *) Byteranges have been completely re-written to be a filter. This
- has been tested, and I believe it is working correctly, but it could
- doesn't work for the Adobe Acrobat plug-in. The output almost matches
- the output from 1.3, the only difference being that 1.3 includes
- a content-length in the response, and this does not.
- [Ryan Bloom]
-
- *) APR read/write functions and bucket read functions now operate
- on unsigned integers, instead of signed ones. It doesn't make
- any sense to use signed ints, because we return the error codes,
- so if we have an error we should report 0 bytes read or written.
- [Ryan Bloom]
-
- *) Always compute the content length, whether it is sent or not.
- The reason for this, is that it allows us to correctly report
- the bytes_sent when logging the request. This also simplifies
- content-length filter a bit, and fixes the actual byte-reporing
- code in mod_log_config.c
- [Ryan Bloom]
-
- *) Remove AP_END_OF_BRIGADE definition. This does not signify what
- it says, because it was only used by EOS and FLUSH buckets. Since
- neither of those are required at the end of a brigade, this was
- really signifying FLUSH_THE_DATA, but that can be determined better
- by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
- buckets now return a length of 0, which is actually the amount of data
- read, so they make more sense.
- [Ryan Bloom]
-
- *) Allow the core_output_filter to save some data past the end of a
- request. If we get an EOS bucket, we only send the data if it
- makes sense to send it. This allows us to pipeline request
- responses. As a part of this, we also need to allocate mmap
- buckets out of the connection pool, not the request pool. This
- allows the mmap to outlive the request.
- [Ryan Bloom]
-
- *) Make blocking and non-blocking bucket reads work correctly for
- sockets and pipes. These are the only bucket types that should
- have non-blocking reads, because the other bucket types should
- ALWAYS be able to return something immediately.
- [Ryan Bloom]
-
- *) In the Apache/Win32 console window, accept Ctrl+C to stop the
- server, but use Ctrl+Break to initiate a graceful restart
- instead of duplicating behavior. [John Sterling]
-
- *) Patch mod_autoindex to set the Last-Modified header based on
- the directory's mtime, and add the ETag header. [William Rowe]
-
- *) Merge the 1.3 patch to add support for logging query string in
- such a way that "%m %U%q %H" is the same as "%r".
- [Bill Stoddard]
-
- *) Port three log methods from mod_log_config 1.3 to 2.0:
- CLF compliant '-' byte count, method and protocol.
- [Bill Stoddard]
-
- *) Add a new LogFormat directive, %c, that will log connection
- status at the end of the response as follows:
- 'X' - connection aborted before the response completed.
- '+' - connection may be kept-alive by the server.
- '-' - connection will be closed by the server.
- [Bill Stoddard]
-
- *) Expand APR for WinNT to fully accept and return utf-8 encoded
- Unicode file names and paths for Win32, and tag the Content-Type
- from mod_autoindex to reflect that charset if the feature
- macro APR_HAS_UNICODE_FS is true. [William Rowe]
-
- *) Compute the content length (and add appropriate header field) for
- the response when no content length is available and we can't use
- chunked encoding. [Jeff Trawick]
-
- *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
- so that content input filters get dechunked data when using
- the default handler. Also removed REQUEST_CHUNKED_PASS.
- [Sascha Schumann]
-
- *) Add mod_ext_filter as an experimental module. This module allows
- the administrator to use external programs as filters. Currently,
- only filtering of output is supported. [Jeff Trawick]
-
- *) Most Apache functions work on EBCDIC machines again, as protocol
- data is now translated (again). [Jeff Trawick]
-
- *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
- the EBCDIC support. They are noops on ASCII machines, so this
- type of translation doesn't have to be surrounded by #ifdef
- CHARSET_EBCDIC. [Jeff Trawick]
-
- *) Fix mod_include. tag commands work again, and the server will
- send the FAQ again. This also allows mod_include to set aside
- buckets that include partial buckets.
- [Ryan Bloom and David Reid]
-
- *) Add suexec support back. [Manoj Kasichainula]
-
- *) Lingering close now uses the socket directly instead of using
- BUFF. This has been tested, but since all we can tell is that it
- doesn't fail, this needs to be really hacked on.
- [Ryan Bloom]
-
- *) Allow filters to modify headers and have those headers be sent to
- the client. The idea is that we have an http_header filter that
- actually sends the headers to the network. This removes the need
- for the BUFF to send headers.
- [Ryan Bloom]
-
- *) Charset translation: mod_charset_lite handles translation of
- request bodies. Get rid of the xlate version of ap_md5_digest()
- since we don't compute digests of filtered (e.g., translated)
- response bodies this way anymore. (Note that we don't do it at
- all at the present; somebody needs to write a filter to do so.)
- [Jeff Trawick]
-
- *) Input filters and ap_get_brigade() now have a input mode parameter
- (blocking, non-blocking, peek) instead of a length parameter.
- [hackathon]
-
- *) Update the mime.types file to the registered media types as
- of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
- Tony Finch]
-
- *) Namespace protect some macros declared in ap_config.h
- [Ryan Bloom]
-
- *) Support HTTP header line folding with input filtering.
- [Greg Ames]
-
- *) Mod_include works again. This should still be re-written, but at
- least now we can serve an SHTML page again.
- [Ryan Bloom]
-
- *) Begin to remove BUFF from the core. Currently, we keep a pointer
- to both the BUFF and the socket in the conn_rec. Functions that
- want to use the BUFF can, functions that want to use the socket,
- can. They point to the same place.
- [Ryan Bloom]
-
- *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
- [Tomas Ögren <stric ing.umu.se>]
-
- *) APR pipes on Unix and Win32 are now cleaned up automatically when the
- associated pool goes away. (APR pipes on OS/2 were already had this
- logic.) This resolvs a fatal file descriptor leak with CGIs.
- [Jeff Trawick]
-
- *) The final line of the config file was not being read if there was
- no \n at the end of it. This was caused by apr_fgets returning
- APR_EOF even though we had read valid data. This is solved by
- making cfg_getline check the buff that was returned from apr_fgets.
- If apr_fgets return APR_EOF, but there was data in the buf, then we
- return the buf, otherwise we return NULL.
- [Ryan Bloom]
-
- *) Piped logs work again in the 2.0 series.
- [Ryan Bloom]
-
- *) Restore functionality broken by the mod_rewrite security fix:
- rewrite map lookup keys and default values are now expanded
- so that the lookup can depend on the requested URI etc.
- PR #6671 [Tony Finch]
-
- *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
- security bug in some mass virtual hosting configurations
- that can allow a remote attacker to retrieve some files
- on the system that should be inaccessible. [Tony Finch]
-
- *) Add a pool bucket type. This bucket is used for data allocated out
- of a pool. If the pool is cleaned before the bucket is destroyed, then
- the data is converted to a heap bucket, allowing it to survive the
- death of the pool.
- [Ryan Bloom]
-
- *) Add a flush bucket. This allows modules to signal that the filters
- should all flush whatever data they currently have. There is no way
- to actually force them to do this, so if a filter ignores this bucket,
- that's life, but at least we can try with this.
- [Ryan Bloom]
-
- *) Add an output filter for sub-requests. This filter just strips the
- EOS bucket so that we don't confuse the main request's core output
- filter by sending multiple EOS buckets. This change also makes sub
- requests start to send EOS buckets when they are finished.
- [Ryan Bloom]
-
- *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
- makes ap_bucket_destroy a return void, which is okay because it
- used to always return APR_SUCCESS, and nobody ever checked its
- return value anyway.
- [Cliff Woolley <cliffwoolley yahoo.com>]
-
- *) Remove the index into the bucket-type table from the buckets
- structure. This has now been replaced with a pointer to the
- bucket_type. Also add some macros to test the bucket-type.
- [Ryan Bloom]
-
- *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
- for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
- and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
- All _VAR_ flavors changes to _DATA to be absolutely clear.
- [William Rowe]
-
- *) Add support for /, //, //servername and //server/sharename
- parsing of <Directory> blocks under Win32 and OS2.
- [Tim Costello, William Rowe, Brian Harvard]
-
- *) Remove the function pointers from the ap_bucket type. They have been
- replaced with a global table. Modules are allowed to register bucket
- types and use then use those buckets.
- [Ryan Bloom]
-
- *) mod_cgid: In the handler, shut down the Unix socket (only for write)
- once we finish writing the request body to the cgi child process;
- otherwise, the client doesn't hit EOF on stdin. Small request bodies
- worked without this change (for reasons I don't understand), but large
- ones didn't. [Jeff Trawick]
-
- *) Remove file bucket specific information from the ap_bucket type.
- This has been moved to a file_bucket specific type that hangs off
- the data pointer in the ap_bucket type.
- [Ryan Bloom]
-
- *) Input filtering now has a third argument. This is the amount of data
- to read from lower filters. This argument can be -1, 0, or a positive
- number. -1 means give me all the data you have, I'll deal with it and
- let you know if I need more. 0 means give me one line and one line
- only. A positive number means I want no more than this much data.
-
- Currently, only 0 and a positive number are implemented. This allows
- us to remove the remaining field from the conn_rec structure, which
- has also been done.
- [Ryan Bloom]
-
- *) Big cleanup of the input filtering. The goal is that http_filter
- understands two conditions, headers and body. It knows where it is
- based on c->remaining. If c->remaining is 0, then we are in headers,
- and http_filter returns a line at a time. If it is not 0, then we are
- in body, and http_filter returns raw data, but only up to c->remaining
- bytes. It can return less, but never more.
- [Greg Ames, Ryan Bloom, Jeff Trawick]
-
- *) mod_cgi: Write all of the request body to the child, not just what
- the kernel would accept on the first write. [Jeff Trawick]
-
- *) Back out the change that moved the brigade from the core_output_filters
- ctx to the conn_rec. Since all requests over a given connection
- go through the same core_output_filter, the ctx pointer has the
- correct lifetime.
- [Ryan Bloom]
-
- *) Fix another bug in the send_the_file() read/write loop. A partial
- send by apr_send would cause unsent data in the read buffer to
- get clobbered. Complete making send_the_file handle partial
- writes to the network.
- [Bill Stoddard]
-
- *) Fix a couple of type fixes to allow compilation on AIX again
- [Victor J. Orlikowski <v.j.orlikowski gte.net>]
-
- *) Fix bug in send_the_file() which causes offset to be ignored
- if there are no headers to send.
- [Bill Stoddard]
-
- *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
- filter. Useful for supporting Windows 9* with a binary
- compiled on Windows NT.
- [Bill Stoddard]
-
-Changes with Apache 2.0a7
-
- *) Reimplement core_output_filter to buffer/save bucket brigades
- across multiple calls to the core_filter. The brigade will be
- sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
- thresholds are hit or the EOS bucket is received.
- [Bill Stoddard]
-
- *) Create experimental filter (buffer_filter) that coalesces bytes
- into one large buffer before invoking the next filter in the
- chain. This filter is particularly useful with the current
- implementation of mod_autoindex when it inserted above the
- chunk_filter. mod_autoindex generates a lot of brigades that
- containing buckets holding just a few bytes each. The
- buffer_filter coalesces these buckets into a single large bucket.
- [Bill Stoddard]
-
- *) Add apr_sendfile() support into the core_output_filter.
- [Bill Stoddard]
-
- *) Add apr_sendv() support into the core_output_filter.
- [Bill Stoddard]
-
- *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
- [Mike Abbott <mja sgi.com>]
-
- *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
- make much sense, because Apache uses buckets instead of BUFFs now.
- [Ryan Bloom]
-
- *) send_the_file now falls back to a read/write loop on platforms that
- do not have sendfile.
- [Ryan Bloom and Brian Havard]
-
- *) Install apachectl correctly, and substitute the proper values so
- that it works again. [Ryan Bloom]
-
- *) Better(??) handle platforms that lack sendfile().
- [Jim Jagielski]
-
- *) APR now has UUID generation/formatting/parsing support.
- [Greg Stein]
-
- *) Begin the http_filter. This is an input filter that understands
- the absolute basic amount required to parse an HTTP Request. The
- goal is to be able to split headers from request body before passing
- the data back to the other filters.
- [Ryan Bloom]
-
- *) Bring forward from 1.3.13 the config directory implementation
- [Jim Jagielski]
-
- *) install apxs if it is created
- [Ryan Bloom]
-
- *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
- conversions. [William Rowe]
-
- *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
- ap_add_output_filter(). [Jeff Trawick]
-
- *) Multiple build and configuration fixes
- Build process:
-
- -add datadir and localstatedir substitutions
- -fix layout name
- -fix logfilename misspelling
- -fix evaluation of installation dir variables and
- -replace $foobar by $(foobar) to be usefull in the makefile
-
- Cross compile:
-
- -add rules for cross-compiling in rules.mk. Okay, rule to check for
- $CC_FOR_BUILD is still missing
- -use CHECK_TOOL instead of CHECK_PROG for ranlib
- -add missing "AR=@AR@" to severaly Makefile.in's
- -cache result for "struct rlimit"
- -compile all helper programs with native and cross compiler
- and use the native version to generate header file
- [Rüdiger Kuhlmann <Tadu gmx.de>]
-
- *) Prepare our autoconf setup for autoconf 2.14a and for cross-
- compiling.
- [Rüdiger Kuhlmann <Tadu gmx.de>]
-
- *) Fix a bug where a client which only sends \n to delimit header
- lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
- message. Start working on ebcdic co-existance with input
- filtering.
- [William Rowe, Greg Ames]
-
- *) If mod_so is enabled in the server always create libexec, even
- if there are no modules installed in this directory. This is a
- requirement for APXS to work correctly.
- [Ryan Bloom]
-
- *) Connection oriented output filters are now stored in the
- conn_rec instead of the request_rec. This allows us to add the
- output filter in the pre-connection phase instead of the
- post_read_request phase, which keeps us from trying to write an
- error page before we have a filter to write to the network.
- [Ryan Bloom, Jeff Trawick, and Greg Ames]
-
- *) Cleaning up an mmap bucket no longer deletes the mmap. An
- mmap can be used across multiple buckets (default_handler with
- byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
- the mmap itself can't be associated with the bucket.
- [Jeff Trawick]
-
- *) Add .dll caching directive ISAPICacheFile to mod_isapi.
- [William Rowe]
-
- *) Radical surgery to improve mod_isapi support under Win32.
- Includes a number of newer ServerSupportFunction calls, support
- for ReadClient (in order to retrieve POSTs greater than 48KB),
- and general bug fixes to more reliably load ISAPI .dll's and
- prevent leaking handle resources. Note: There are still
- discrepancies between IIS's and Apache's ServerVariables, and
- async calls are still not supported. Additional warnings are
- logged to facilitate debugging of unsupported ISAPI calls.
- [William Rowe]
-
- *) Add input filtering to Apache. The basic idea for the input
- filters is the same as the ideas for output filters. The biggest
- difference is that instead of calling ap_pass_brigade, ap_get_brigade
- should be called, and the order of execution for the filter itself is
- different. When writing an output filter, a brigade is passed in,
- and filters operate directly on that brigade, when done, they call
- ap_pass_brigade. Input filters are the exact opposite. Because input
- is not a push operation, filters first call ap_get_brigade. When this
- function returns, the input filter will be left with a valid brigade.
- The input filter should then operate on the brigade, and return.
- [Ryan Bloom]
-
- *) Fix building on BSD/OS using its native make. The build system
- falls back to the BSD .include directive on that host platform.
- [Sascha Schumann]
-
- *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
- SHA1 and plaintext password encodings. Make feature tests a
- bit more flexible. [William Rowe]
-
- *) Charset translation: mod_charset_lite handles output content
- translation in a filter. mod_charset_lite no longer ignores
- subrequests. A bunch of cruft related to BUFF's support for
- translating request and response bodies was removed.
- [Jeff Trawick]
-
- *) Move the addition of the CORE filter to the post_read_request
- hook in http_core.c. This removes the need to add the filter in
- multiple places and allows for an SSL module to be added much
- simpler. [Ryan Bloom]
-
- *) SECURITY: CVE-2000-0913 (cve.mitre.org)
- Fix a security problem that affects certain configurations of
- mod_rewrite. If the result of a RewriteRule is a filename that
- contains expansion specifiers, especially regexp backreferences
- $0..$9 and %0..%9, then it may be possible for an attacker to
- access any file on the web server. [Tony Finch]
-
- *) Fix a bug where errors that are detected during early request parsing
- don't produce visible HTTP error messages at the browser, because
- the core_filter wasn't present. [Greg Ames]
-
- *) Provide apr_socklen_t as a portability aid.
- [Victor J. Orlikowski]
-
- *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
- as well as a comment arg to the add, adduser and update cmds.
- update allows the user to clear or preserve pw/groups/comment.
- Fixed a bug in dbmmanage that prevented the check option from
- parsing a password followed by :group... text. Corrected the
- seed calcualation for Win32 systems, and added -lsdbm support.
- [William Rowe]
-
- *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
- [William Rowe]
-
- *) Avoid a segfault when parsing .htaccess files. An
- uninitialized tree pointer was passed to ap_build_config().
- [Jeff Trawick]
-
- *) Change the way that inet_addr & inet_network are checked for
- in APR's configure process to allow BeOS BONE to correctly
- find them. With this change BeOS BONE now builds from source
- with no problems. [David Reid]
-
- *) Fix a bug in apr_create_process() for Unix. The NULL signifying
- the end of the parameters to execve() was stored in the wrong
- location, overlaying the storage beyond the newargs[] array and
- also passing uninitialized storage to execve(), which would
- sometimes fail with EFAULT. [Jeff Trawick]
-
- *) Fix a bug parsing configuration file containers. With a sequence
- like this in the config file
-
- <IfModule mod_kilroy.c>
- any stuff
- </IfModule>
- <IfModule mod_lovejoy.c>
- (blank line)
- any stuff
- </IfModule>
-
- the second container would be terminated at the blank line due to
- sediment in the buffer from reading the prior </IfModule> and an
- error message would be generated for the real </IfModule> for the
- second container. Also due to this problem, any two characters
- could be used for "</" in the close of a container.
- [Jeff Trawick]
-
- *) ap_add_filter prototype changed to remove the ctx pointer. The
- pointer still remains in the filter structure, but it can not be
- a part of the ap_add_filter prototype. The reason is that when
- the core uses AddFilter to add a filter to the stack it doesn't
- know how to allocate the ctx pointer, or even how much memory should
- be allocated. The filters will have to be responsible for allocating
- the ctx memory when they need it.
- [Ryan Bloom]
-
- *) Add an AddFilter directive. This directive takes a list of filters
- that should be activated for the requested resource.
- [Ryan Bloom]
-
- *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
- some other platforms). [Jeff Trawick]
-
- *) Modify mod_include to be a filter. Currently, it has only been tested
- on actual files, but it should work for CGI scripts too.
- [Ryan Bloom]
-
- *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
- writes. apr_flush() for Unix: handle interrupted writes.
- [Jeff Trawick]
-
- *) NameVirtualHost can now take "*" as an argument instead of
- an IP address. This allows you to create a purely name-based
- virtual hosting server that does not have any IP addresses in
- the configuration file and which ignores the local address
- of any connections. PR #5595, PR #4455 [Tony Finch]
-
- *) Fix some compile warnings in mod_mmap_static.c
- [Mike Abbott <mja sgi.com>]
-
- *) Fix chunking problem with CGI scripts. The general problem was that
- the CGI modules were adding an EOS bucket and then the core added an
- EOS bucket. The chunking filter finalizes the chunked response when it
- encounters an EOS bucket. Because two EOS buckets were sent, we
- finalized the response twice. The fix is to make sure we only send one
- EOS, by utilizing a flag in the request_rec.
- [Ryan Bloom]
-
- *) apr_put_os_file() now sets up the unget byte appropriately on Unix
- and Win32. Previously, the first read from an apr_file_t set up via
- apr_put_os_file() would return a '\0'. [Jeff Trawick]
-
- *) Mod_cgid now creates a single element bucket brigade, with a pipe
- bucket, instead of using BUFF's and ap_r*.
- [Ryan Bloom]
-
- *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
- [Mike Abbott <mja sgi.com>]
-
- *) Remove ap_bopenf from buff code. This required modifying the file_cache
- code to use APR file's directly instead of going through BUFFs.
- [Ryan Bloom]
-
- *) Fix compile break on some platforms for mod_mime_magic.c
- [John K. Sterling <sterling covalent.net>]
-
- *) Fix merging of AddDefaultCharset directive.
- PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
-
- *) Minor revamp of the rlimit sections of code. We now test
- explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
- is now "available" even if the platform doesn't support
- the rlimit family (it's just a noop though). [Jim Jagielski]
-
- *) Migrate the pre-selection of which MPM to use for specific
- platforms to hints.m4, which contains (or should contain)
- all platform specific "hints". [Jim Jagielski]
-
- *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
- [Ryan Bloom]
-
- *) Add tables with non-string/binary values to APR.
- [Ken Coar]
-
- *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
- [Jeff Trawick]
-
- *) Update PCRE to version 3.2. [Ryan Bloom]
-
- *) Change the way buckets' destroy functions are called so that
- they can be more directly used when changing the type of a
- bucket in place. [Tony Finch]
-
- *) Add generic support for reference-counting the resources used by
- buckets, and alter the HEAP and MMAP buckets to use it. Change
- the way buckets are initialised to support changing the type of
- buckets in place, and use it when setting aside TRANSIENT buckets.
- Change the implementation of TRANSIENT buckets so that it can be
- mostly shared with IMMORTAL buckets, which are now implemented.
- [Tony Finch]
-
-Changes with Apache 2.0a6
-
- *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
-
- *) Add a chunking filter to Apache. This brings us one step closer
- to removing BUFF. [Ryan Bloom]
-
- *) ap_add_filter now adds filters in a LIFO fashion. The first filter
- added to the stack is the last filter to be called. [Ryan Bloom]
-
- *) Apache 2.0 has been completely documented using Scandoc. The
- docs can be generated by running 'make docs'. [Ryan Bloom]
-
- *) Add filtered I/O to Apache. This is based on bucket brigades,
- Currently the buckets still use BUFF under the covers, but that
- should change quickly. The only currently written filter is the
- core filter which just calls ap_bwrite. [The Apache Group]
-
- *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
- built with thread support. [Jeff Trawick]
-
- *) Abort configuration if --with-layout was specified and there's
- no layout definition file. [Ken Coar]
-
- *) Add support for '--with-port=n' option to configure. [Ken Coar]
-
- *) Add support for extension methods for the Allow response header
- field, and an API routine for accessing r->allowed and the
- list of extension methods in a unified manner. [Ken Coar]
-
- *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
- [Rob Simonson <simo us.ibm.com>]
-
- *) Get xlate builds working again. The apr renaming in 2.0a5 broke
- APACHE_XLATE builds. [Jeff Trawick]
-
- *) A configuration file parsing problem was fixed. When the
- configuration file started with an IfModule/IfDefine container,
- only the last statement in the container would be retained.
- [Jeff Trawick]
-
-Changes with Apache 2.0a5
-
- *) Perchild is serving pages after passing them to different child
- processes. There are still a lot of bugs, but this does work. I
- have made requests against the same installation of Apache, and had
- different servers use different user IDs to serve the responses.
- This change moves to using socketpair instead of an AF_UNIX socket.
- [Ryan Bloom]
-
- *) Perchild MPM still doesn't work perfectly, but it is serving pages.
- It can't seem to pass between child processes yet, but I think we
- are closer now than before. This moves us back to using Unix
- Domain Sockets. [Ryan Bloom]
-
- *) libapr functions and types renamed with apr_ prefix.
- #include "apr_compat.h" for 1.3.x backwards compat
- [Perl]
-
- *) Fix problems with APR sockaddr handling on Win32. It didn't always
- return the right information on the local socket address.
- [Gregory Nicholls <gnicholls level8.com>]
-
- *) ap_recv() on Win32: Set bytes-read to 0 on error.
- [Gregory Nicholls <gnicholls level8.com>]
-
- *) Add an option to not detach from the controlling terminal without
- going into single process mode. This allows for much easier
- debugging of the process startup code. [Ryan Bloom]
-
- *) ab: don't use perror() to report the failure of an APR function.
- [Jeff Trawick]
-
- *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
- scoreboard on graceful restarts.
- [Ryan Bloom]
-
- *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
- An invalid ap_proc_t was passed to ap_create_process().
- [Jeff Trawick]
-
- *) Allow modules to register filters. Those filters are still
- never called, but this is a step in the right direction.
- [Ryan Bloom and Greg Stein]
-
- *) Register the mod_cgid daemon process for cleanup so that it is
- killed at termination if it does not die when the parent gets
- SIGTERM. This change is to fix occasional problems where the
- process stays around. Bugs in similar logic in mod_rewrite and
- mod_include were also fixed. [Jeff Trawick]
-
- *) Fix a bug in the time handling. Basically, we were imploding a time
- in ap_parseHTTPdate, but it had bogus data in the exploded time format.
- Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
- uses those two fields to adjust the time value. Because of the HTTP
- spec, both of those values can be zero'ed out safely. This fixes
- the bug correctly. [Ryan Bloom]
-
- *) Fix a couple of place in the Windows code where the wrong error
- code was being returned. [Gregory Nicholls <gnicholls level8.com>]
-
- *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
-
- *) Added the APR_EOL_STR macro for platform dependent differences in
- logfiles and other raw text (such as all APR files). Fixes logfiles
- not terminated with cr/lf sequences in Win32. [William Rowe]
-
- *) Move all strings functions in APR to src/lib/apr/strings and create
- apr_strings.h for the prototypes. [Ryan Bloom]
-
- *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
- to repeat the syscall until we stop getting EINTR. I noticed a
- related problem at termination (SIGTERM) on FreeBSD when using
- fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
- implementation work properly with child init. Previously, ap_lock()
- was essentially a no-op because all children were using different
- locks and thus nobody ever blocked. [Jeff Trawick]
-
- *) The htdocs/ tree has been moved out of the CVS source tree into
- a separate area for easier development. This has NO EFFECT on
- end-users or Apache installations. [Ken Coar]
-
- *) Integrate the mod_dav module for WebDAV protocol handling. This
- adds the dav and dav_fs modules, the SDBM library, and additional
- XML handling utilities. [Greg Stein]
-
- *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
- [Greg Stein]
-
- *) Update the lib/expat-lite/ library (bring forward changes from
- the Apache 1.3 repository). [Greg Stein]
-
- *) If sizeof(long long) == sizeof(long), then prefer long in APR
- configure.in. [Dave Hill <ddhill zk3.dec.com>]
-
- *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
- machines where sendfile is detected, but nobody has written ap_sendfile.
- [Dave Hill <ddhill zk3.dec.com>]
-
- *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
-
- *) ab would start up more connections than needed, then quit when the
- desired number were finished. Also fixed a logic error involving
- ab keepalives. [Victor J. Orlikowski]
-
- *) WinNT: Implement non-blocking pipes with timeouts to communicate
- with CGIs. Apache 2.0a4 had non-blocking pipes but without
- timeouts (i.e, if a timeout was specified, the pipe reverted to
- a full blocking pipe). Now the behaviour is more in line with
- Unix non-blocking pipes.
- [Bill Stoddard]
-
- *) WinNT: Implement accept socket reuse. Using mod_file_cache to
- cache open file handles along with accept socket reuse enables
- Apache 2.0 to serve non-keepalive requests for static files at
- 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
- and Apache 2.0 will serve almost 1200 rps on my system).
- [Bill Stoddard]
-
- *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
- supports two config directives, mmapfile (same behavious as
- mod_mmap_static) and cachefile. Use the cachefile directive
- to cache open file handles. This directive only works on systems
- that have implemented the ap_sendfile API. cachefile works today
- on Windows NT, but has not been tested on any flavors of Unix.
- [Bill Stoddard]
-
- *) Cleanup the configuration. With the last few changes the
- configuration process automatically:
- inherits information about how to build from APR. Allowing
- APR to inform Apache that it should or should not use -ldl
-
- Detects which mod_cgi should be used mod_cgi or mod_cgid,
- based on the threading model
-
- Apache calls APR's configure process before finishing it's
- configuration processing, allowing for more information flow
- between the two.
- [Ryan Bloom]
-
-
- *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
- with non-zero argument makes the socket non-blocking. BeOS and
- OS/2 already worked this way. [Jeff Trawick]
-
- *) ap_close() now calls ap_flush() for buffered files, so write
- operations work a whole lot better on buffered files.
- [Jeff Trawick]
-
- *) Fix error messages issued from MPMs which explain where to change
- compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
- [Greg Ames]
-
- *) ap_create_pipe() now leaves pipes in blocking state. (This helps
- reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
- now the way that the blocking state of a pipe is manipulated.
- ap_block_pipe() is gone. [Jeff Trawick]
-
- *) Correct the problem where the only local host name that the IP stack
- can discover are 'undotted' private names. If no fully qualified
- domain name can be identified, the default ServerName will be set to
- the machine's IP address string. A warning is always provided if the
- ServerName not specified, but assumed. Solves PR6215 [William Rowe]
-
- *) Repair problems with config file processing which caused segfault
- at init when virtual hosts were defined and which caused ServerName to
- be ignored when there was no valid DNS setup. [Jeff Trawick]
-
- *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
-
- *) Add ap_sendfile implementation for AIX
- [Victor J. Orlikowski]
-
- *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
- apr_network_io.h, and apr_thread_proc.h.
- [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
-
- *) Bring the allocation and pool debugging code back into a working
- state. This will need to be tested as so far it's only been used on
- BeOS. [David Reid]
-
- *) Change configuration command setup to be properly typesafe when in
- maintainer mode. Note that this requires a compiler that can initialise
- unions. [Ben Laurie]
-
- *) Turn on buffering for config file reads. Part of this was to
- repair buffered I/O support in Unix and implement buffered
- ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
-
- *) Win32: Fix problem where UTC offset was not being set correctly
- in the access log. Problem reported on news group by Jerry Baker.
- [Bill Stoddard]
-
- *) Fix segfault when reporting this type of syntax error:
- "</container> without matching <container> section", where
- container is VirtualHost or Directory or whatever.
- [Jeff Trawick]
-
- *) SECURITY: CVE-2000-1204 (cve.mitre.org)
- Prevent the source code for CGIs from being revealed when
- using mod_vhost_alias and the CGI directory is under the document root
- and a user makes a request like http://www.example.com//cgi-bin/cgi
- as reported in <news:960999105.344321 ernani.logica.co.uk>
- [Tony Finch]
-
- *) Add support for the new Beos NetwOrking Environment (BONE)
- [David Reid]
-
- *) xlate: ap_xlate_conv_buffer() now tells the caller when the
- final input char is incomplete; ap_bwrite_xlate() now handles
- incomplete final input chars. [Jeff Trawick]
-
- *) Yet another update to saferead/halfduplex stuff -- need to ensure
- that a bhalfduplex call occurs before logging or else DNS and
- such can delay the last packet of the response. [Dean Gaudet]
-
- *) Some syscall reduction in APR on unix -- don't seek when setting
- up an mmap; and don't fcntl() more than once per socket.
- [Dean Gaudet]
-
- *) When mod_cgid is started as root, the cgi daemon now switches
- to the configured User/Group (like other httpd processes)
- instead of continuing as root. [Jeff Trawick]
-
- *) The prefork MPM now uses an APR lock for the accept() mutex.
- It has not been getting a lock at all recently. httpd -V now
- displays APR's selection of the lock mechanism instead of the
- symbols previously respected by prefork. [Jeff Trawick]
-
- *) Change the mmap() feature test to check only for existence.
- The previous check required features not used by Apache.
- [Greg Ames]
-
- *) Fix a couple of bugs in mod_cgid: The cgi arguments were
- sometimes mangled. The len parm to accept() was not
- initialized, leading sometimes to an endless loop of failed
- accept() calls on OS/390 and anywhere else that failed the call
- if the len was negative. Use <sys/un.h> for struct sockaddr_un
- instead of declaring it ourselves to fix a compilation problem
- on Solaris. [Jeff Trawick]
-
- *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
-
- *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
-
- *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]

- *) Fix storage overlay when loading dsos. Symptom: Apache dies at
- initialization if ALLOC_DEBUG is defined; no known symptom
- otherwise. [Jeff Trawick]
-
- *) Fix typo in configure script when checking for mod_so. bash
- doesn't seem to have a problem but /bin/sh on Solaris does.
- Symptom: "./configure: test: unknown operator =="
- [Jeff Trawick]
-
- *) Rebind the Win32 NT and 9x services control into the MPM.
- All console, WinNT SCM and Win9x pseudo-service control code is
- now wrapped within the WinNT MPM.
- [William Rowe]
-
- *) Make a copy of getenv("PATH") before storing for later use. Some
- getenv() implementations use the same storage for successive calls.
- CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
-
- *) Server Tokens work in 2.0 again. This also propogates the change
- to allow just the product name in the server string using
- PRODUCT_ONLY.
- [Ryan Bloom]
-
-Changes with Apache 2.0a4
-
- *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
- won't need to call it. [Greg Ames, Jeff Trawick]
-
- *) Move pre_config hook call to between configuration read and config
- tree walk. This allows all modules to implement pre_config hooks
- and know that they will be called at an appropriate time.
- [Ryan Bloom]
-
- *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
- [Jeff Trawick]
-
- *) Add pre-config hooks back to all modules.
- [Ryan Bloom]
-
- *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
- ContentDigest enabled and we can't/don't mmap the file.
- [Jeff Trawick]
-
- *) We now report the correct line number for syntax errors in config
- files. [Ryan Bloom, Greg Stein, Jeff Trawick]
-
- *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
- related bugs, and changed shmem/locking to use apr API. Shared-mem
- is currently disabled, however, because of problems with graceful
- restarts. [Ronald Tschalär]
-
- *) Fix corruption of IFS variable in --with-module= handling.
- Depending on the user's shell or customization thereof, there
- would be errors generating ap_config_auto.h later in the configure
- procedure. [Jeff Trawick]
-
- *) mod_cgi: Restore logging of stderr from child process when ScriptLog
- isn't used (as in 1.3), except that on Unix it is now logged via
- ap_log_rerror() instead of by the child having STDERR_FILENO refer
- to the error log. [Greg Ames, Jeff Trawick]
-
- *) Add '-D' argument processing for run time configuration defines.
- [William Rowe]
-
- *) Organize http_main.c as independent code, such that no code or
- global data is exported from it. WIN32 will dynamically link it
- to the server core, so this will prevent mutual dependency.
- [William Rowe]
-
- *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
- and APR_VAR_EXPORT to correctly resolve apr functions and globals.
- [William Rowe]
-
- *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
- [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
-
- *) Add mod_charset_lite for configuring character set translation.
- [Jeff Trawick]
-
- *) Add '-n' option to htpasswd to make it print its user:pw record
- on stdout rather than having to frob a text file. [Ken Coar]
-
- *) Fix saferead. Basically, we flush the output buffer if a read on the
- input will block.
- [Ryan Bloom]
-
- *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
- a conversion is single-byte only. [Jeff Trawick]
-
- *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
- the BeOS 5.0 documentation says that shutdown doesn't work yet.
- [Roy Fielding]
-
- *) Fix some minor errors where pid was being manipulated as an int
- instead of the portable pid_t. [Roy Fielding]
-
- *) Fix some error log prints that were printing the pointer to a
- structure rather than the pid within the structure.
- [Jeff Trawick, Roy Fielding]
-
- *) ab: Fix a command-line processing bug; track bad headers in
- err_response; support reading headers up to 2K.
- [Ask Bjoern Hansen <ask valueclick.com>]
-
- *) Fix ap_resolve_env() so that it handles new function added in a prior
- alpha (see "Added the capability to do ${ENVVAR} constructs in the
- config file.") as well as the constructs used by mod_rewrite.
- [Paul Reder <rederpj raleigh.ibm.com>]
-
- *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
-
- *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
- APR to perform translation, instead of accessing the hard-coded tables
- in 1.3's ebcdic.c. [Jeff Trawick]
-
- *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
- [Jeff Trawick]
-
- *) Add the ability to hook into the config file reading phase. Basically
- if a directive is specified EXEC_ON_READ, then when that directive is
- read from the config file, the assocaited function is executed. This
- should only be used for those directives that must muck with HOW the
- server INTERPRETS the config. This should not be used for directives
- that re-order or replace items in the config tree. Those changes should
- be made in the pre-config step.
- [Ryan Bloom]
-
- *) Add mod_example to the build system.
- [Tony Finch]
-
- *) APR: Add ap_xlate_conv_byte() to convert one char between single-
- byte character sets. [Jeff Trawick]
-
- *) Pick up various EBCDIC fixes from 1.3 (from Martin
- Kraemer and Oliver Reh originally according to the change log).
- [Jeff Trawick]
-
- *) Fix a couple of problems in RFC1413 support (controlled by the
- IdentityCheck directive). Apache did not build the request string
- properly and more importantly Apache would loop forever if the
- would-be ident server dropped the connection before sending a
- properly terminated response. [Jeff Trawick]
-
- *) apxs works in 2.0.
- [Ryan Bloom]
-
- *) Reliable piped logs work in 2.0.
- [Ryan Bloom]
-
- *) Introduce a hash table implementation into APR to be used for
- replacing tables and other random data structures in Apache.
- [Tony Finch]
-
- *) Add some more error reporting to htpasswd in the case of problems
- generating or accessing the temporary file. Also, pass in a
- buffer if the implementation knows how to use it (i.e., if L_tmpnam
- is defined). [Ken Coar]
-
- *) Configure creates config.nice now containing your configure
- options. Syntax: ./config.nice [--more-options]
- [Sascha Schumann]
-
- *) Fix various return code problems in APR on Win32. For most of
- these, APR was returning APR_EEXIST instead of GetLastError()/
- WSAGetLastError(). [Jeff Trawick]
-
- *) Make piped logs work again in version 2.0
- [Ryan Bloom]
-
- *) Add VPATH support to UNIX build system of Apache and APR.
- [Sascha Schumann]
-
- *) Fix ap_tokenize_to_argv to respect the const arguments that are
- passed to it.
- [Ryan Bloom]
-
- *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
- Patch submitted to author.
- [Sascha Schumann]
-
- *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
- /sbin in PATH on FreeBSD (all submitted to rse previously)
- [Jeff Trawick]
-
- *) Fix building Pthread-based MPMs on OpenBSD
- [Sascha Schumann] PR#26
-
- *) Fix ap_readdir() problem on systems where d_name[] field in
- struct dirent is declared with only one byte. (This problem only
- affected multithreaded builds.) This caused a segfault during
- pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
- least). [Jeff Trawick]
-
- *) Fix some make-portability problems on at least Tru64, Irix
- and UnixWare.
- [Sascha Schumann] PR#18, PR#39
-
- *) Add ap_sigwait() to support old-style sigwait() on systems
- like OS/390 and UnixWare.
- [Sascha Schumann]
-
- *) Add POSIX-thread flags for more platforms.
- [Sascha Schumann]
-
- *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
- (on Unix, at least) to handle resolver errors. Fix a bug in
- the definition of APR_ENOMEM so that ap_strerror() can spit
- out the correct error message for it.
- [Jeff Trawick]
-
-Changes with Apache 2.0a3
-
- *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
- [Doug MacEachern]
-
- *) API: *HOOK* macros now have an AP_ prefix
- [Doug MacEachern]
-
- *) Win32: Eliminate redundant calls to initialize winsock.
- [Tim Costello <timcostello ozemail.com.au>]
-
- *) Fix bugs initializing ungetchar for pipes.
- [Chia-liang Kao <clkao CirX.ORG>]
-
- *) The ab program in the src/support directory is now portable using
- APR.
- [Ryan Bloom]
-
- *) Support directory is being compiled when the server is built
- [Ryan Bloom]
-
- *) The configure option --with-program-name has been added to allow
- developers to rename the executable at configure time. This also
- changes the name of the config files to match the executable's name.
- [Ryan Bloom]
-
- *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
- containing version numbers. [Martin Pool]
-
- *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
- Unix; access_log and error_log now created with these perms; non-
- Unix is unaffected [Jeff Trawick]
-
- *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
- Replaced more magic numbers with MD5_DIGESTSIZE.
- [William Rowe, Roy Fielding]
-
- *) Win32: Get mod_auth_digest compiling and added to the Windows
- build environment. Not tested and I'd be suprised if it
- actually works. [Bill Stoddard]
-
- *) Revamp the Win32 make environment. Makefiles have been removed and
- Apache.dsw created to bring together all the pieces. Create new file
- os/win32/BaseAddr.ref to define module base addresses (to prevent
- dll relocation at start-up).
- [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
-
- *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
- of the \015, \012, and \015\012 constants with macros.
- [Greg Ames]
-
- *) Add ap_xlate_open() et al for translation of text between different
- character sets. The initial implementation requires iconv().
- [Jeff Trawick]
-
- *) More FAQs and answers from comp.infosystems.www.servers.unix.
- [Joshua Slive <slive finance.commerce.ubc.ca>]
-
- *) CGI output is being timed out now.
- [Ryan Bloom]
-
- *) Fix the problem with dieing quietly. dupfile now takes a pool which
- is used by the new apr file. There is no reason to create a new file
- with the same lifetime as the original file.
- [Ryan Bloom]
-
- *) Win32: Attempt to eliminate dll relocation at start-up by specifying
- module base addresses. This will help shooting seg faults
- in the field. [William Rowe <wrowe lnd.com>]
-
- *) Update Apache on Windows documentation. Add new document
- describing how to compile Apache on Windows.
- [William Rowe <wrowe lnd.com>]
-
- *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
- microseconds instead of seconds. Some storage leaks and other
- minor bugs in related code were fixed. [Jeff Trawick]
-
- *) Win32: First cut at getting mod_isapi working under 2.0
- [William Rowe <wrowe lnd.com>]
-
- *) First stab at getting mod_auth_digest working under 2.0
- quick change summary:
- - moved the random byte generation (ap_generate_random_bytes) into APR
- - now uses ap_time_t
- - compiles and runs on linux
- - tested with amaya
- [Brian Martin <bmartin penguincomputing.com>]
-
- *) Win32: Move the space stripping of physical service names
- fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
- unresolved symbol. Add dependency checking to the
- CreateService call to ensure TCPIP and AFP (winsock) is started
- before Apache.
- [William Rowe <wrowe lnd.com>]
-
- *) Win32: Add code to perform latebinding on functions that may
- not exist on all levels of Windows where Apache runs. This
- is needed to allow Apache to start-up on Win95/98. All calls
- to non portable functions should be protected with
- ap_oslevel checks to prevent runtime segfaults.
- [William Rowe <wrowe lnd.com>]
-
- *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
-
- *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
-
- *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
- This addresses PR 1623. Still need to address timing out runaway
- CGI scripts. [Bill Stoddard]
-
- *) Win32: Make ap_stat Windows 95/98 friendly
- [William Rowe <wrowe lnd.com>]
-
- *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
- always fail. Need to initialise the dwOSVersionInfoSize member of the
- OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
- always fails.
-
- The patch also enhances ap_get_oslevel (and the associated enum) to
- handle selected service packs for NT4, and adds recognition for
- Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
- we can use ReadFileScatter and WriteFileGather in readwrite.c.
- [Tim Costello <Tim.Costello BTFinancialgroup.com>]
-
- *) Get mod_rewrite building and running, and mod_status building for Win NT
- [Allan Edwards <ake raleigh.ibm.com>]
-
- *) Patch to port mod_auth_db to the 2.0 api and also to support
- Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
- 2.7.7. It should work with version 1 as well but I haven't tested it.
- [Brian Martin <bmartin penguincomputing.com>]
-
- *) Get APR DSO code working under Windows. Includes cross platform
- fixes to mod_so.c.
- [<Tim.Costello BTFinancialgroup.com>]
-
- *) Fix some of the Windows APR time functions.
- [William Rowe]
-
- *) FAQ changes related to tidying up historical documents on the web site.
- [Joshua Slive <slive finance.commerce.ubc.ca>]
-
- *) Move Windows DSO code into APR.
- [Bill Stoddard]
-
- *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
- Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
- at build time. At this point, the server will not compile on Windows because
- of the recent DSO commits. Fixing those next.
- [Bill Rowe & Bill Stoddard]
-
- *) Added error checking for file I/O APR routines.
- [Jon Travis <jtravis covalent.net>]
-
- *) APR: Don't use the values of resolver error codes for the
- corresponding APR error codes. On Unix and Win32, return the
- proper APR error code after a resolver error. [Jeff Trawick]
-
-Changes with Apache 2.0a2
-
- *) Renamed the executable back to httpd on all platforms other
- than Win32
- [Ryan Bloom]
-
- *) Allow BeOS to survive restarts, log properly and a few
- small things it had problems with due to the way it setup
- users and groups. [David Reid]
-
- *) Get mod_rewrite working with APR locks
- [Paul Reder <rederpj raleigh.ibm.com>]
-
- *) Actually remove the sempahore when the lock cleanup routine
- is called on BeOS. [David Reid]
-
- *) Clear hook registrations between reads of the config file.
- When DSOs are unloaded and re-loaded the old hook pointers may
- no longer be valid. This fix eliminates potential segfaults.
- [Allan Edwards <ake raleigh.ibm.com>]
-
- *) Fix a problem with Sigfunc not being defined or bypassed
- if sigaction() wasn't found. [Jim Jagielski]
-
- *) Fix the locking mechanism on BSD variants. They now use fcntl
- locks. This allows the server to start and serve pages.
- [Ryan Bloom]
-
- *) First cut at getting the Win32 installer to work
- [William Rowe <wrowe lnd.com>]
-
- *) Get htpasswd compiling under Windows
- [William Rowe <wrowe lnd.com>]
-
- *) Change the log message for a bind() failure to show the
- interface and port number. [Jeff Trawick]
-
- *) Import the documentation from 1.3.12 and bring parts of it
- up-to-date with respect to the changes that have occurred
- in 2.0.
- [Tony Finch]
-
- *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
- now logged correctly on BeOS.
- [David Reid]
-
- *) Create one makefile for all Win32 distributions (NT/2000/95/98).
- Makefile.win includes the same user interface as the old
- Makefile.nt
- [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
-
- *) Win32 exec now uses COMSPEC environment string for command
- shell path resolution.
- [William Rowe <wrowe lnd.com>] PR#3715
-
- *) Win32: ap_connect() was not returning correct error condition
- PR5866
- [Allen Prescott <allen clanprescott.com>]
-
- *) Win32: ap_open() was broken on Win9x because an NT-specific
- flag was passed to CreateFile. ap_puts() added an unnecessary
- '\n'.
- [Jeff Trawick <trawick us.ibm.com>]
-
- *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
- which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
- confusing ee/et name and made all extensions language/dialect
- rather than country reflecting. Changed example files to
- explicit reflect the ISO charset and added a few common
- ones to the example config [dirkx]
-
- *) Extend external module capability. To use this, you call
- configure with --with-module=path/to/mod1,path/to/mod2,etc.
- [Ryan Bloom]
-
- *) Backported the various "default charset" fixes from 1.3.12,
- including the AddDefaultCharset directive. [Jim Jagielski]
-
- *) Added the capability to do ${ENVVAR} constructs in the
- config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
- it does this on a line by line basis; i.e. if the envvar
- expands to something with spaces you have to protect it
- by adding quotes around it (Unless of course you expect it
- to contains more than one argument. Alternatively you
- can compile it on a per token basis; which is what people
- usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
- hampers fancier hacks.
- [Dirk-Willem van Gulik]
-
- *) Changed the 'ErrorDocument' syntax in that it NO longer
- supports the asymetric
-
- ErrorDocument 301 "Some message
-
- Note the opening " quote, without a closing quote. It now
- has either the following syntaxes
-
- ErrorDocument XXX /local/uri
- ErrorDocument XXX http://valid/url
- ErrorDocument XXX "Some Message"
-
- The recognition heuristic is: if it has a space it
- is a message. If it has no spaces and starts with a /
- or is a valid URL then treat it that way. Otherwise it
- is assumed to be a message.
-
- This breaks backward compatibility but makes live a hell
- of a lot easier for GUI's and config file parsers.
- [Dirk-Willem van Gulik]
-
- *) Changed 'CacheNegotiatedDocs' from its present/not-present
- syntax into a 'on' or 'off' syntax. As it currently is the
- only non nesting token which uses NO_ARGS and thus is an
- absolute pain for any config interface automation. This
- breaks backward compatibility. [Dirk-Willem van Gulik]
-
- *) Add ability to add external modules to the build process. This is
- done with --with-module=/path/to/module. Modules can only be added
- as static modules at this point.
- [Ryan Bloom]
-
-Changes with Apache 2.0a1
-
- *) Fix FreeBSD 3.3 core dump.
- Basically, ap_initialize() needs to get called before
- create_process(), since create_process() passes op_on structure
- to semop() to get a lock, but op_on isn't initialized until
- ap_initialize() calls setup_lock(). Here is a slight
- rearrangement to main() which calls ap_initialize() earlier...
- [Jeff Trawick <trawick us.ibm.com>]
-
- *) Enable Apache to use sendfile/TransmitFile API
- [Bill Stoddard, David Reid, Paul Reder]
-
- *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
- APIs.
- [Bill Stoddard]
-
- *) Make file I/O and network I/O writev/sendv APIs consistent.
- Eliminate use of ap_iovec_t and use Posix struct iovec.
- Use seperate variable on ap_writev to set the number of iovecs
- passed in and number of bytes written.
- [Bill Stoddard]
-
- *) Adapt file iol to use APR functions. Replaced ap_open_file()
- with ap_create_file_iol(). ap_create_file_iol() requires that
- the file be opened prior to the call using ap_open().
- [Bill Stoddard]
-
- *) Port mod_include and mod_cgi to 2.0
- [Paul Reder, Bill Stoddard]
-
- *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
- bytes_read/bytes_written is always valid (never -1). Plus
- some fixes to buff.c to correct problems introduced by the
- errno => ap_status_t changes a while back. Plus a fix to
- chunked encoding introduced right at the beginning of 2.0.
- [Dean Gaudet]
-
- *) Revamped UNIX build system to use autoconf and libtool.
- [Manoj Kasichainula, Sascha Schumann]
-
- *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
-
- *) SECURITY: More rigorous checking of Host: headers to fix security
- problems with mass name-based virtual hosting (whether using mod_rewrite
- or mod_vhost_alias).
- [Ben Hyde, Tony Finch]
-
- *) Add back support for UseCanonicalName in <Directory> containers.
- [Manoj Kasichainula]
-
- *) Added APLOG_STARTUP log type. This allows us to write an error
- message without any of the date and time information. As a part
- of this change, I also removed all of the calls to fprintf(stderr
- and replaced them with calls to ap_log_error using APLOG_STARTUP
- writing to stderr is no longer portable, because we don't direct
- stderr to the error log on all platforms.
- [Ryan Bloom]
-
- *) Convert error logging functions to take errno as an argument.
- This makes our error logs more portable, because some Windows API's
- don't set errno. This change allows us to still output a valid
- message on all of our platforms.
- [Ryan Bloom]
-
- *) mod_mime_magic runs in 2.0-dev now.
- [Paul Reder <rederpj raleigh.ibm.com>]
-
- *) sendfile has been added to APR.
- [John Zedlewski <zedlwski Princeton.EDU>]
-
- *) buff.c has been converted to no longer use errno.
- [Manoj Kasichainula]
-
- *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
- interface adaption to APR functions did it. [Martin Kraemer]
-
- *) Support DSOs properly on 32-bit HP-UX 11.0
- [Dilip Khandekar <dilip cup.hp.com>]
-
- *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
- [Ralf S. Engelschall]
-
- *) Cleaned APR build environment integration and bootstrap APR
- automatically for developers from src/Configure.
- [Ralf S. Engelschall]
-
- *) Fixed building of src/support/htpasswd.c
- [Ralf S. Engelschall]
-
- *) When generating the Location: header, mod_speling forgot
- to escape the spelling-fixed uri. (Forw-Port from 1.3)
- [Martin Kraemer]
-
- *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
-
- *) Change all pools to APR contexts. This is the first step to
- incorporating APR into Apache. [Ryan Bloom]
-
- *) Move "handler not found" warning message to below the check
- for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
- PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
-
- *) Support line-continuation feature in config.option file and
- allow the loading of multiple option sections at once via
- ``--with-option=<section1>,<section2>,...''
- [Ralf S. Engelschall]
-
- *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
-
-Changes with Apache MPM
-
- *) Use asynchronous AcceptEx() and a completion port to accept and
- dispatch connections to threads in Windows NT/2000.
- [Bill Stoddard]
-
- *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
- [Bill Stoddard]
-
- *) Implement the APACI --with-option facility
- (per default used the config.option file).
- [Ralf S. Engelschall]
-
- *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
-
- *) Start to implement module-defined hooks that are a) fast and b) typesafe.
- Replace pre_connection module call with a register_hook call and
- implement pre_connection as a hook. The intent is that these hooks will
- be extended to allow Apache to be multi-protocol, and also to allow the
- calling order to be specified on a per-hook/per-module basis.
- [Ben Laurie]
-
- *) Implement mpm_* methods as "modules". Each method gets its own
- subdir in src/modules (eg: src/modules/prefork). Selection
- of method uses Rule MPM_METHOD. [Jim Jagielski]
-
- *) Port the hybrid server from the apache-apr repository as
- mpm_mpmt_pthread. [Manoj Kasichainula]
-
- *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
- amongst the unix MPMs.
-
- *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
- signal handling for the new world order. [Dean Gaudet]
-
- *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
- of alloc.c for now. [Dean Gaudet]
-
- *) Handle partial large writes correctly. [Ben Laurie]
-
- *) Eliminate conn_rec's pointer to server. All it knows is the base server
- based on IP/port. [Ben Laurie]
-
- *) Port a bunch of modules to the new module structure.
- ["Michael H. Voase" <mvoase midcoast.com.au>]
-
- *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
-
- *) Basic restructuring to introduce the MPM concept; includes various
- changes to the module API... better described by
- docs/initial_blurb.txt. [Dean Gaudet]
-
-Changes with Apache pthreads
-
- *) New buff option added: BO_TIMEOUT. It describes the timeout for
- buff operations (generally over a network).
- [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
-
- *) Created http_accept abstraction. Added 4 new functions (not exported):
- init_accept(), begin_accepting_requests(), get_request(),
