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.

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 |
