- 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)

- section allowing other threads to use the connection pool
- during maintenance. (mturk)

- 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)

- 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)

- 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)

- local_worker_only is missing from the list of deprecated
- attributes (and not supported either), so prevents the web

- 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.
