+ The Apache Tomcat Connector - Miscellaneous Documentation
+
+ Changelog
+
+ Preface
+ This is the Changelog for Tomcat Connectors. 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

+ fix 46579: IIS: Use local environment table instead environment
+ variables for setting the JKISAPI_PATH and JKISAPI_NAME.
+ (mturk)
+ update LB: Add new property error_escalation_time to fine tune
+ escalation of local errors to global errors. (rjung)
+ update LB: If the sticky session affinity mark contains a dot, treat
+ the part before the dot as the domain name. This allows to
+ have full node session affinity with domain failover. (mturk)
+ fix LB: make forced recovery work with local error states. (rjung)
+ fix LB: Only update error state and error time, if we actually
+ have a new state. (rjung)

+ 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)

+ per-uri basis using new use_server_errors extension. (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)

+ 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 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.

+ and ajp lb members. (rjung)
+ update Status: Change parameter names of update action to make them
+ more easily distinguishable from other parameters. (rjung)
+ add Status: Add ajp worker statistics also for workers, that are
+ not lb members. (rjung)
+ update AJP: Refactor factories, move ajp13/ajp14 common parts into
+ ajp_factory. (rjung)
+ update Status: Only sync shm worker config values of the workers for
+ which we changed values. (rjung)

+ multiple text links. (rjung)
+ update SHM: Use local copies of read mostly attributes of lb sub
+ workers in lb and status worker. (rjung)
+ update Status: Add "dump" action to dump our initial configuration.
+ (rjung)
+ update Status: Use property table to decide which cmd action uses
+ which output elements. (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)

+ fix 44116: Fix handling of multiple JSESSIONID cookies. (rjung)
+ fix 37850: Use thread safe localtime_r where appropriate. (rjung)
+ fix Use thread safe strtok_r on more platforms, especially AIX.
+ (rjung)
+ update Status: Improve XSS hardening. (rjung)
+ update 35303: Move initialization of service members with defaults
+ from web server specific code to our generic
+ jk_init_ws_service() function. (rjung)
+ fix 36385: Add missing prepost CPing/CPong directly after connect
+ in case prepost CPing is used, but no connect CPing. (rjung)

+ in which JKStatus itself was called. (rjung)
+ update JKStatus: Enhance URI to worker map listing. Update stale
+ uriworkermap.properties immediately. (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

+ 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

+ update Replace APR precompiler directive by httpd mpm_query to detect
+ MPM threading. Add a debug log message about auto-detected
+ pool size. (rjung)
+ fix Make MMN check easier to understand and a little more precise
+ (for new ap_get_server_banner()/ap_get_server_description()).
+ We use the new API only for Apache httpd 2.3. This way our
+ binaries are not tightly coupled to a minor 2.0 version, and
+ we don't use ap_get_server_banner() any way. (rjung)
+ fix Use the full description string ap_get_server_description()
+ instead of the truncated info from ap_get_server_banner(),
+ because this info gets used internally (status worker display
+ and ajp14 backend communication) and is not send back to the
+ normal user. (rjung)

+ page. (mturk)
+ update Added load balancer method directive that is used for setting

+ Native
+ update Added new property named recover_time that can be used to
+ change the default 60 second recover time. (mturk)
+ update Added custom retries for worker, so we don't depend on default
+ setting. If set to a number grater then 3, it will sleep for
+ 100ms on retry greater then 3 and then try again. (mturk)
+ update Added JkWorkerProperty directive that enables omiting
+ workers.properties file. For example: JkWorkerProperty
+ worker.ajp13a.port=8009. (mturk)
+ fix Check all JSESSIONID cookies for a valid jvmRoute. If you have
+ multiple Tomcats with overlapping domains, then you can get
+ multiple cookies without a defined order. This will route
+ correctly as long as the different domains don't have any
+ Tomcats in common. (billbarker)
+ update Added JkUnMount directive for negative mappings that works as
+ opposite to JkMount directives. It is used for blocking of
+ particular URL or content type. (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.
