| 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. |

| <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) |
| </fix> |
| <fix> |
| Always build with thread support, unless flag --enable-prefork |
| is set during for configure. (rjung) |
| </fix> |
| <update> |
| i5/OS (AS/400) V5R4 port where Apache 2.0 modules should now use UTF8. (hgomez) |

| <update> |
| Docs: Add comments on i5/OS build for V5R4 and previous releases. (hgomez) |

| <changelog> |
| <update> |
| Change the default value of JkOptions to ForwardURICompatUnparsed. |
| The old default value was ForwardURICompat. |
| This should make URL interpretation between Apache httpd and |
| Tomcat consistent (prevent double decoding problems). (rjung) |

| <changelog> |
| <fix> |
| Refactor line endings logging to make it correct for all |
| platforms and webservers. (mturk) |
| </fix> |
| <update> |
| Added command line windows make files. (mturk) |
| </update> |
| <update> |
| Allow fail_on_status directive to be multi line. (mturk) |
| </update> |
| <fix> |
| <bug>42076</bug>: Fix name of new option from ForwardCertChain to |
| ForwardSSLCertChain as documented. (rjung) |
| </fix> |
| <fix> |
| Docs: Fix a couple of typos, change format of a few tables, |
| fix links to news pages. (rjung) |
| </fix> |
| <fix> |
| Fix correct URL for TC 6 examples in new IIS rewrite.properties |
| configuration example file. (rjung) |
| </fix> |
| <fix> |
| Add svn properties to several files. (rjung) |
| </fix> |
| <update> |
| Add TC 6 examples to uriworkermap.properties in config examples. (rjung) |
| </update> |
| <update> |
| Allow multiple status codes for fail_on_status directive. |
| The status codes can be delimited by space or comma characters. (mturk) |
| </update> |
| <update> |
| IIS. Added pcre like regular expressions for url rewrite rules. (mturk) |
| </update> |
| <fix> |
| <bug>41922</bug>: Apache 1.3. Enable JkEnvVar. (mturk) |
| </fix> |
| <update> |
| Apache. Add --enable-flock configure parameter for explicit |
| compilation of faster flock() system calls for OS supporting |
| those calls. By default the fcntl system call for locking will |
| be used that is a little bit slower but it can work on NFS |
| mounted volumes as well. (mturk) |
| </update> |
| <fix> |
| <bug>41562</bug>: Add Debug logging for read from client in ISAPI Redirector. |
| Contributed by Tim Whittington. (mturk) |
| </fix> |
| <update> |
| Apache. Add ForwardSSLCertChain JkOption. |
| Contributed by Patrik Schnellmann. (mturk) |
| </update> |
| <fix> |
| IIS. Do not forbid access to web-inf or meta-inf if there is |
| no mapped worker. This allows to have resource with those names |
| that are outside mapped contexts. (mturk) |
| </fix> |
| <update> |
| Apache. Use process id for creating shared memory name and delete shared |
| memory and shared memory lock files on exit. (mturk) |
| </update> |
| <fix> |
| IIS. Fix Keep-Alive regression introduced in 1.2.21. (mturk) |
| </fix> |
| <update> |
| Delete unused check for empty init_map during startup. (rjung) |
| </update> |
| <fix> |
| <bug>41770</bug>: Fix startup error if no JkWorkersFile is used. (rjung) |
| </fix> |
| <update> |
| Use JK_TRUE/JK_FALSE instead of OK/!OK as return values in init_jk(). (rjung) |
| </update> |
| <update> |
| Minor adjustments to apache startup log messages (when to use STDERR, remove |
| deprecated NOERRNO flag, shm warning and warnings for usage of default files). (rjung) |
| </update> |
| <update> |
| Replace APR precompiler directive by httpd mpm_query to detect MPM threading. |
| Add a debug log message about auto-detected pool size. (rjung) |
| </update> |
| <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> |
| <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) |
| </fix> |
| <fix> |
| <bug>41757</bug>: Document the "--enable-prefork" flag of configure. (rjung) |
| </fix> |
| <update> |
| Enhance log messages for failures when parsing attribute maps. (rjung) |
| </update> |
| <fix> |
| Correct log message during worker initialization, in case remote host could not be |
| resolved. We logged the default host name "localhost" instead of the configured one. (rjung) |
| </fix> |
| <fix> |
| <bug>41770</bug>: Fix the second part of the bug: local_worker and local_worker_only |
| is missing from the list of deprecated attributes (and not supported either), so prevents |
| the web server from startup. (rjung) |
| </fix> |

| lbfactor is <i>how much we expect this worker to work</i>, |
| or <i>the worker's work quota</i>. |
| lbstatus is <i>how urgent this worker has to work to fulfill its quota |
| of work</i>. 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) |
