| This is the Changelog for Apache 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. |

| <update> |
| Apache: Update the documentation to note additional limitations of the |

| over five years. (markt) |
| </update> |
| <update> |
| <bug>57946</bug>: Apache: Update the documentation to use httpd 2.4.x |

| limitations of select triggering an httpd crash. Patch provided by Koen |
| Wilde. (markt) |
| </fix> |
| <fix> |
| <bug>60745</bug>: ISAPI: Remove the check that rejects requests that |
| contain path segments that match WEB-INF or META-INF as it duplicates |
| a check that Tomcat performs and, because ISAPI does not have visibility |
| of the current context path, it is impossible to implement this check |
| without valid requests being rejected. (markt) |

| now effectively hard-coded to CollpaseSlashesAll due to the changes |
| made to align normalization with that implemented in Tomcat. (markt) |

| <fix> |
| Status: Fix displayed number of bytes read from and written |
| to the backend when an AJP worker is used without a load |
| balancer worker. (rjung) |
| </fix> |
| <fix> |
| Apache: Don't try to read remaining request body parts during |
| clean up if reading the request body from the client already |
| failed during earlier processing phases. (rjung) |
| </fix> |
| <fix> |
| <bug>57485</bug>: Apache: Propagate errors reading the request body from |
| the client to mod_jk so Tomcat sees an error rather than a truncated |
| body. (markt) |

| <fix> |
| <bug>57836</bug>: ISAPI: Empty REMOTE_USER should not be |
| translated to "". (rjung) |

| <bug>58309</bug>: ISAPI: Update bundled pcre from version 5.0 |
| to 8.38. (rjung) |
| </update> |
| <fix> |
| <bug>58286</bug>: Fix crash in mod_jk and in the ISAPI Redirector. |
| The crash only happens on Windows when retrieving the jk-status |
| for the HTML format (which is the default format). This regression |
| was introduced by the fix to <bug>54177</bug>. (rjung) |
| </fix> |
| <fix> |
| <bug>58285</bug>: Don't use GCC atomics on platforms, for which |
| GCC doesn't provide an atomics implementation. This regression |
| was introduced by the fix to <bug>44454</bug> and <bug>56703</bug>. |
| (rjung) |
| </fix> |

| workers from initialising. Note that the AJP 1.2 protocol is deprecated. |
| Patch provided by yagisita. (markt) |

| </fix> |
| <fix> |
| <bug>58608</bug>: ISAPI: Add a new registry option "flush_packets" |
| that allows the flushing behaviour of IIS7+ to be controlled. The |
| default is not to flush. Setting the option to "true" with cause IIS to |
| write data to the client as each AJP packet is received. (markt) |
| </fix> |
| <fix> |
| <bug>58813</bug>: ISAPI: Correctly release a mutex allowing the plugin |

| Reiter. (markt) |

| <fix> |
| AJP, LB: Reduce lock contention during maintenance function. |
| This was observable when using a big number of AJP13 and LB |
| workers, especially in combination with the Apache httpd prefork |
| MPM. (rjung) |
| </fix> |
| <fix> |
| <bug>57060</bug>: Allow building from outside of source tree. |
| Patch contributed by Petr Sumbera. (rjung) |

| of backend connections especially when a connection timeout occurred |
| on the backend. (rjung) |
| </fix> |
| <fix> |
| <bug>56661</bug>: Fix Servlet API getLocalAddr(). |

| plugins. (rjung) |
| </fix> |
| <update> |
| Status: Log old and new values when changing worker attributes. |

| </fix> |
| <fix> |
| Apache: Copy log notes instead of using references to prevent access |
| to memory from closed pool. (rjung) |
| </fix> |
| <add> |
| Add option to control handling of multiple adjacent slashes in |
| mount and unmount. New default is collapsing the slashes only in |
| unmount. Configuration is done via new JkOption for Apache |
| ("CollapseSlashesAll", "CollapseSlashesNone" or |
| "CollapseSlashesUnmount") and via property "collapse_slashes" for IIS |
| (values "all", "none", "unmount"). This is the fix for CVE-2014-8111. |
| (rjung) |
| </add> |
| <add> |
| Add more checks for shared memory allocation. (rjung) |
| </add> |

| <fix> |
| <bug>52334</bug>: LB: Calculate worker recovery time based on last |
| recovery attempt time instead of original error time after the first |
| recovery attempt. (rjung) |
| </fix> |
| <fix> |
| <bug>54596</bug> part 1: IIS: Fix missing last character when parsing |
| relative file names with no ".." directory components from |
| configuration. (rjung) |
| </fix> |
| <fix> |
| <bug>54596</bug> part 2: IIS: Fix using relative file names in config |
| with ".." path segments that go up the directory hierarchy higher |
| than the starting point of the relative file name. (rjung) |
| </fix> |
| <fix> |
| Status: Add logging if status worker output was dropped due to |
| insufficient buffer size. (rjung) |
| </fix> |
| <fix> |
| Reduce log buffer from 8KB to 1KB. Add logging in case of failed |
| logging and add trailing "..." to lines which were likely truncated. |
| (rjung) |
| </fix> |
| <update> |
| Replace fixed allocation of 32 entries for fail_on_status by |
| dynamic allocation. (rjung) |
| </update> |
| <add> |
| Enforce implementation restriction on maximal length "60" of worker |

| <bug>52483</bug>: Apache: Add debug logging for result |
| of JkOptions configuration processing. (rjung) |
| </add> |
| <fix> |
| <bug>54177</bug>: Status: Use numeric time stamps instead of |
| textual ones to avoid non-well-formed XML output. Textual |
| timestamps are formatted according to locale settings and |
| reencoding them to UTF-8 would be cumbersome. (rjung) |
| </fix> |
| <fix> |
| <bug>56618</bug>: Status: Use percent decoding when reading |
| query string parameters. For example this fixes editing IPv6 |
| addresses via the status worker if the client encodes |
| ":" as "%3A". Patch contributed by Christopher Schultz. (rjung) |
| </fix> |
| <fix> |
| <bug>56452</bug>: Fix crash in debug logging for IPv6 adresses. |
| Patch contributed by Christopher Schultz. (rjung) |
| </fix> |
| <fix> |
| <bug>34526</bug>: Apache: Improve compatibility with mod_deflate |
| request body inflation. An automatic detection of mod_deflate |
| inflation is not implemented. Use the new Apache environment variable |
| JK_IGNORE_CL instead, to let mod_jk ignore an existing Content-Length |
| request header. (rjung) |
| </fix> |
| <update> |
| <bug>44454</bug>: LB: Add warning to docs about problems with |
| "busyness" load balancing method. (rjung) |

| <bug>44454</bug>: Improve busy counter by using atomics. (rjung) |
| </fix> |
| <fix> |
| <bug>56703</bug>: Status: Improve connected counter. Use atomics |
| and for mod_jk (Apache) currectly count down connections closed |
| by child processes that are stopped. (rjung) |
| </fix> |
| <fix> |
| <bug>44571</bug>: Ensure that we return with status 503 if we |
| can not get and endpoint for a worker. (rjung) |
| </fix> |
| <fix> |
| Apache: Improve log handling during graceful or normal restart. |
| (rjung) |
| </fix> |
| <fix> |
| Don't update last access time of worker connections during optional |
| checking of idle connections using CPing. Updating the time stamp |
| breaks closing idle connections. (rjung) |
| </fix> |
| <fix> |
| Adjust linger parameters used during connection shutdown. (rjung) |
| </fix> |
| <fix> |
| Fix annoying redefine warnings for the autoconf PACKAGE defines |
| during configure based builds. (rjung) |
| </fix> |
| <fix> |
| Status: Use multi-line table headers and fix invalid xml output. |
| (rjung) |
| </fix> |
| <fix> |
| <bug>44571</bug>: Implement an optional limit on concurrent requests |
| allowed for a worker (attribute "busy_limit"). Original patch |
| contributed by zealot0630 at gmail dot com. (rjung) |
| </fix> |
| <fix> |
| Correct log message "all endpoints are disconnected" to |
| "no usable connection found, will create a new one". Tone done |
| from info log level to debug for the common case. (rjung) |
| </fix> |
| <add> |
| <bug>57536</bug>: AJP: Allow to configure connection source address. |
| This should only be used on multi-homed hosts. The feature is |
| experimental. (rjung) |

| Changed the load balancer algorithm. |
| The idea behind this new scheduler is the following: |
| 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) |
