This changelog does not + contain all updates and fixes to the Tomcat connectors (yet). It should + contain fixes made only after November 10th 2004, when the new + documentation project for JK was started. + + Changes between 1.2.31 and 1.2.32 + Native + fix 51417: Fix worker busy detection by querying the worker + endpoint. Abandoned connections can leave a worker in busy + state without decrementing busy counter. (mturk) + fix 50339: Fix whitespace trimming when parsing attribute lists. + (rjung) + fix 41263: Support Servlet API getRemotePort(). Works for Tomcat + 5.5.28, 6.0.20 and 7.0.0 and Apache and ISAPI plugins. (rjung) + fix 41923: AJP: Close AJP connection to Tomcat on client write + error when recovery_options 4 is specified, aborting the + response write on the Tomcat side. (timw) + update AJP: Cap the lingering bytes that will be read when shutting + down an AJP socket at 32k to prevent CPU spikes in the web + server when a client aborts on a large response body. Also + reduce total linger time to 2s. (timw) + fix 50839: AJP: Fix 30sec CPU spike due to incorrect counting of + lingering bytes causing a busy loop when a client aborts + connection during a response write. Fixes regression in + 1.2.31. (timw) + add LB: Forward worker activation state as request attribute + "JK_LB_ACTIVATION". Possible values are "ACT" (active), "DIS" + (disabled) and "STP" (stopped). (rjung) + fix HTTPD: Forward WWW-Authenticate from backend when status is + 401 and server generated error pages are used. (rjung) + fix 50363: IIS: Prevent chunk encoding of empty message bodies for + 204, 205 and 304 responses. (timw) + fix 50975: IIS: Fix hanging of Transfer-Encoding: chunked requests + when Content-Length header is present in request as well. Also + addresses situation where IIS appears to create a + Content-Length header for a small chunk encoded request when + none was present in the original request. (timw) + fix 47679: IIS: stop truncation of request headers when ISAPI + redirector used as an extension without the corresponding + filter installed. (timw) + fix NSAPI: Use lower case header names for responses. Otherwise + the web server might add chunked transfer encoding header in + addition to our content length header. + update Docs: Improve load balancer documentation. (rjung) + + Changes between 1.2.30 and 1.2.31 + Native + fix 49413: AJP13: Drop flush packets send by the backend after the + response has been finished. (rjung) + update AJP: Log the local and remote socket address. (mturk) + update Watchdog: Move the maintain workers outside the critical + section allowing other threads to use the connection pool + during maintenance. (mturk) + update Common: Add svn revision to init log message. (rjung) + fix Common: Don't destroy errno during trace logging. (rjung) + update Apache: Add support for Apache 2.3/2.4. (rjung) + update Apache: Added version number resource for mod_jk.so on + Windows. (timw) + update 48501: IIS: Added rotatelogs style log rotation to ISAPI + Redirector. (timw) + fix 38895: IIS: Use RAW headers instead of CGI headers by default + to prevent conversion of underscores '_' to hyphens '-' in + header names. Old behaviour can be enabled by defining + USE_CGI_HEADERS. (timw) + fix 49511: IIS: Do not override IIS log information when + subsequent requests on a keep-alive connection are not mapped + into the ISAPI Redirector. (timw) + fix Docs: Document SSLOptions needed for SSL information + forwarding. (rjung) + update Docs: Grammar and style improvements and clarification about + serving static content by IIS. Patch provided by André + Warnier. (rjung) + fix Docs: Update subversion paths used in docs. (rjung) + + Changes between 1.2.28 and 1.2.30 + Native + update Apache: Improve compatibility with Apache 2.3.

(mturk) + add Status: Add number of open backend connections to status + worker. This feature is experimental, the displayed value + might not be accurate. (mturk) + update 47224: Status: When address gets changed invalidate all opened + sockets in the endpoint cache. This will cause new backend + connections to get opened using new address. (mturk) + fix 48305: Status: Do not show "secret" property when doing dump. + (mturk) + fix 45610: Status: Don't accept requests with empty value for sub + worker parameter.

(rjung) + fix IIS: Fix memory corruption due to parallel initialization by + multiple threads. (rjung) + update Windows: Use non-default socket keepalive interval. (mturk) + add IIS: Add environment variables JKISAPI_PATH and JKISAPI_NAME. + (mturk) + add Added socket_connect_timeout directive for setting the connect + timeout for the socket. This enables to have low connection + timeout but higher operational timeouts. (mturk) + fix AJP13: [CVE-2008-5519] Always send initial POST packet even if + the client disconnected after sending request but before + providing POST data. In that case or in case the client broke + the connection in a middle of read send an zero size packet + informing container about broken client connection. (mturk) + add AJP13: Added connection_acquire_timeout directive for setting + the absolute timeout the worker will wait for a free endpoint. + (mturk) + update Apache: Allow to set path parameter used when doing + JkStripSession.

(mturk) + add Added session_cookie and session_path for configuring default + session identifiers. (mturk) + update Use max_packet_size also as TCP send and receive buffer size. + (mturk) + update Apache: Do not allow Apache to start in multi-threaded mode if + mod_jk was only build for single threaded server (prefork). + (mturk) + fix 45812: Add done() service method that causes sending EOS + bucket for Apache httpd 2.x. This allows filter chain to work + properly. (mturk) + add Added connection_ping_interval, ping_timeout and ping_mode + directives. (mturk) + fix Apache: Use correct ld flags provided by apxs when building + module. Prevents some crashes on AIX for httpd 1.3 module. + (rjung) + fix Documentation: "val" attribute numbering in status worker + needs to start with 0 instead of 1.

(rjung) + fix 45026: For Apache httpd 2.x add "Unknown Reason" as the reason + phrase, if we get an empty one from the backend. Otherwise + httpd 2.x returns status 500. (rjung) + fix Build: Fix Cygwin build. (rjung) + update Documentation: Add info to docs, that variables sent via + JkEnvVar are not listed in request.getAttributeNames(). + (rjung) + add Add watchdog background thread for Apache 2.x and IIS doing + internal maintenance (idle connection checks, backend + probing). See JkWatchdogInternal (Apache) and + watchdog_interval (IIS). (mturk) + update Change log level of some messages from error to info. (mturk) + fix Documentation: Fix docs for worker attribute "secret". (rjung) + update Detect correct plugin name for various web servers via + additional preprocessor defines. (rjung) + fix LB: Do not put loadbalancer node in error state if there is + opened channel. This fixes the bug when new connection fails + due to busyness, causing opened connections fail stickyness. + This brings back per-node busy counter and private state array + for each request. We can mark the state as error for failover + to work while still operating and reporting node as OK if + there are opened working connections. (mturk) + fix 44738: Fix merging of JkOption ForwardURI* between virtual + hosts. Patch contributed by Toshihiro Sasajima. (rjung) + add URI Map: Add extension attributes to uri worker map. Allowed + are reply_timeout, active/disabled/stopped and fail_on_status. + Usage currently only implemented for httpd and IIS. + (rjung+mturk) + fix URI Map: Make dynamic reloading atomic and free memory not + needed any longer. (rjung) + add Configure: Don't use post httpd 2.2.0 API functions when + building with new --enable-api-compatibility configure switch. + (rjung) + fix Apache: JkAutoAlias does not work in combination with + JkMountCopy if there are no JkMount in virtual host.

(rjung) + update Common: Include original configuration map in worker_env to + make it available for workers, e.g. the status worker. (rjung) + update LB: Refactor "route" return for httpd note. Don't use a member + of the worker_record, because that's not thread safe. (rjung) + update Common: Refactor "retries", remove from service and jk_worker, + move into ajp worker instead. (rjung) + update SHM: Use distinct structs for lb and ajp13 in shm. Improves + type safety and saves a few bytes. (rjung) + update SHM: Remove unused attributes.

(rjung) + update NSAPI: Improve Solaris and Linux Makefiles for nsapi build. + (rjung) + fix Build: Improve pid_t type detection during configure on + Solaris. (rjung) + update Build: Experimental build support for gcc on WIN32 and + Netware. (fuankg) + update Build: Makefile optimizations for Apache httpd 1.3/Netware . + (fuankg) + fix General: Fix missing flush bug introduced in 1.2.24. (rjung) + + Changes between 1.2.23 and 1.2.24 + Native + update Documentation: Improved workers.properties description in the + reference guide. (rjung) + update Documentation: Add a HowTo about the various timeouts. rjung) + update Logging: add milliseconds to the default timestamp format, if + we have gettimeofday(). (rjung) + update Apache: add milliseconds (%Q) and microseconds (%q) as + possible JkLogStampFormat conversion specifiers. This does not + use strftime(), but needs gettimeofday(). (rjung) + update IIS & Sun: Log service failures also, if return code is + negative. (rjung) + fix 42849: Abort startup of Apache httpd 1.3 in case mod_jk + initialization failed. We already do the same for Apache httpd + 2.x. (rjung) + fix 42849: Refuse to operate with IIS in case the initialization + failed. Instead requesting isapi_redirect.dll 500 will be + returned to the user. This is as closest as it can get to + Apache Httpd where we refuse to start the server in case of + fatal initialization errors. (mturk) + fix Load Balancer: Fix a deadlock in lb worker, which was exposed + on Solaris for threaded Apache MPMs. (rjung) + update Logging: handle LWP IDs as 32 Bit unsigned. Try to make it + work, although pthread IDs are opaque. (rjung) + update JkStatus: Added manipulation of max_reply_timeouts. (rjung) + update LB, Status: Add feature max_reply_timeouts, to make lb + tolerant against occasional long running requests. (rjung) + update JkStatus: Added OK/IDLE as the successor of N/A. (rjung) + update Status worker: Renamed runtime states. All states have a major + state (OK or ERR) and a substate. Changed the name N/A to + OK/IDLE. Added docs about the meaning of the states to the + status worker page in the reference guide. No new states have + been added to code. (rjung) + update Common: Add recovery options for recovering idempotent http + methods HEAD and GET. (rjung) + fix Correct documentation for worker attributes retries and + recovery_options. (rjung) + fix Make writing log lines and line endings more atomic. (rjung) + update Common: Refactored and unified jk_map_read_prop* and + jk_map_load_prop* for all use cases. (rjung) + update Common/Apache/IIS/Netscape: Add an option to check decoded + URLs for potentially malicious constructions. (rjung) + update IIS: Document auth_complete and uri_select. (rjung) + update Apache/IIS/Netscape: Change the default forwarding encoding to + the new proxy method. (jfclere, rjung) + update Common: Optionally reencode URIs before forwarding to the + backend. Based on the URI reencoding done bei httpd mod_proxy. + (jfclere, rjung) + update Common: auto-detect correct print format for pid_t. This fixes + at least compiler warnings on Solaris. (rjung) + fix 42608: Handle Content-length as unsigned 64Bit to allow for + huge up- and downloads. (rjung) + update Apache: Add forwarding uri to debug log. (rjung) + update Docs: Clarify relation between worker names and jvmRoute for + load balancing. (rjung) + fix Use initial zero timeout for jk_is_socket_connected. The + resulting detection is the same but offers a huge performance + increase with mod_jk. In most cases the Operating System does + not favor the 1 microsecond timeout, but it rather rounds that + up to much higher value (frequency of interrupt timer which on + most systems defaults to 100Hz). Patch provided by David + McLaughlin. (mturk) + update NSAPI: Check correct log file and shm file configuration + during startup. (rjung) + fix NSAPI: Add support for the general options concerning retries, + flushing and connection persistance. (rjung) + fix NSAPI: fix crashes due to use of mount attribute in + workers.properties. Changed initialization order. (rjung) + fix Improved handling of libtool and discrepancies between CC env + variable and CC used during apache build by configure script. + (rjung) + fix Always build with thread support, unless flag --enable-prefork + is set during for configure. (rjung) + update Use snprintf/vsnprintf from ap_snprintf.c for platforms other + than Windows, which might lack snprintf/vsnprintf + implementations when NOT build for Apache httpd 2.x/APR (e.g. + Sub Web Server) or without using configure.

(mturk) + update Added wildchar match uri mappings. One can now use JkMount to + map /app/*/servlet/* or /app?/*/*.jsp. (mturk) + update Rewrite the logging by adding Trace options. (mturk) + update Added socket_timeout property that sets the timeout for the + socket itself. (mturk) + fix Changed socket_timeout property to recycle_timeout. This + better explains what the directive actually does. (mturk) + fix Changed the load balancer algorithm. The idea behind this new + scheduler is the following: lbfactor is how much we expect + this worker to work, or the worker's work quota. lbstatus is + how urgent this worker has to work to fulfill its quota of + work. We distribute each worker's work quota to the worker, + and then look which of them needs to work most urgently + (biggest lbstatus). This worker is then selected for work, and + its lbstatus reduced by the total work quota we distributed to + all workers. Thus the sum of all lbstatus does not change.(*) + If some workers are disabled, the others will still be + scheduled correctly. (mturk) + + JK 2 + JK2 has been put in maintainer mode and no further development will + take place. The reason for shutting down JK2 development was the lack + of developers interest. Other reason was lack of users interest in + adopting JK2, caused by configuration complexity when compared to JK. + --------------------------------------------------------------------------- + Copyright © 1999-2011, Apache Software Foundation |
