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
- - - - - - - - - - - - - - -
- 51417: Fix worker busy detection by querying the - worker endpoint. Abandoned connections can leave a worker - in busy state without decrementing busy counter. (mturk) -
- 50339: Fix whitespace trimming when parsing attribute - lists. (rjung) -
- 41263: Support Servlet API getRemotePort(). - Works for Tomcat 5.5.28, 6.0.20 and 7.0.0 and Apache and ISAPI - plugins. (rjung) -
- 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) -
- 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) -
- 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) -
- LB: Forward worker activation state as request attribute - "JK_LB_ACTIVATION". Possible values are "ACT" (active), - "DIS" (disabled) and "STP" (stopped). (rjung) -
- HTTPD: Forward WWW-Authenticate from backend when status is 401 - and server generated error pages are used. (rjung) -
- 50363: IIS: Prevent chunk encoding of empty message - bodies for 204, 205 and 304 responses. (timw) -
- 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) -
- 47679: IIS: stop truncation of request headers when - ISAPI redirector used as an extension without the corresponding - filter installed. (timw) -
- 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. -
- Docs: Improve load balancer documentation. (rjung) -

- Documentation: Improved workers.properties description in the - reference guide. (rjung) -
- Documentation: Add a HowTo about the various timeouts. rjung) -
- Logging: add milliseconds to the default timestamp format, - if we have gettimeofday(). (rjung) -
- Apache: add milliseconds (%Q) and microseconds (%q) as possible - JkLogStampFormat conversion specifiers. This does not use strftime(), - but needs gettimeofday(). (rjung) -
- IIS & Sun: Log service failures also, if return code is negative. (rjung) -
- 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) -
- 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) -
- Load Balancer: Fix a deadlock in lb worker, which was exposed on Solaris - for threaded Apache MPMs. (rjung) -
- Logging: handle LWP IDs as 32 Bit unsigned. Try to make - it work, although pthread IDs are opaque. (rjung) -
- JkStatus: Added manipulation of max_reply_timeouts. (rjung) -
- LB, Status: Add feature max_reply_timeouts, to make lb tolerant against - occasional long running requests. (rjung) -
- JkStatus: Added OK/IDLE as the successor of N/A. (rjung) -
- 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) -
- Common: Add recovery options for recovering idempotent http methods - HEAD and GET. (rjung) -

- Apache: Add forwarding uri to debug log. (rjung) -
- Docs: Clarify relation between worker names and jvmRoute for load balancing. (rjung) -
- 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.

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) -
- 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) -
- 41757: Document the "--enable-prefork" flag of configure. (rjung) -
- Enhance log messages for failures when parsing attribute maps. (rjung) -

- Added new property named recover_time that can be used to change the - default 60 second recover time. (mturk) -
- 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) -
- Added JkWorkerProperty directive that enables omiting workers.properties file. - For example: JkWorkerProperty worker.ajp13a.port=8009. (mturk) -
- 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) -
- 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) -
- Added wildchar match uri mappings. One can now use JkMount to - map /app/*/servlet/* or /app?/*/*.jsp. (mturk) -
- Rewrite the logging by adding Trace options. (mturk) -
- Added socket_timeout property that sets the timeout - for the socket itself. (mturk) -
- Changed socket_timeout property to recycle_timeout. This better - explains what the directive actually does. (mturk) -
- 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) -
