* Fixed makefile for static linking zlog-chk-conf.
-- [Hardy Simpson] <[email protected]>
zlog (1.2.4) unstable; urgency=medium
* No longer maintains thread_list; checks configuration for updates during each log write.

* Corrected rule.c, capped path_buf.
-- [Hardy Simpson] <[email protected]>
zlog (1.1.1) unstable; urgency=medium
* Corrected rule.c, avoided using FILE* to prevent interleaved logs.
-- [Hardy Simpson] <[email protected]>
zlog (1.1.0) unstable; urgency=medium

zlog (1.0.0) unstable; urgency=medium
* Changed configuration file layout.
* Made reload atomic, falling back to old on failure.

-- [Hardy Simpson] <[email protected]>
zlog (0.9) unstable; urgency=medium
* Shifted towards an object-oriented approach.
* Used arraylist instead of linklist as an internal data structure.
* Improved configuration file format.
* Created a thread-safe logging function library.

* Handled syslog output, though syslog was found slow.
* Traditional mode for rotation, polling, etc.
* Added zlog_profile API for diagnosing configuration memory.
* Added MDC with configurable additional fields.
* Tested buffer rewriting to ensure trailing \0.
* Renamed xlog to zlog.
* Retrieved ZLOG_ERROR_LOG and ZLOG_DEBUG_LOG once to avoid multiple getenv calls.
* Closed zc_assert by default, opened for debugging.
* Added match for !.*, matching unmatched categories.
* Changed priority to level.
* Customizable level.
* Syslog open in rule.
* Moved default format to global configuration.
* Reset level using arraylist.
* Introduced ylog, simplified interface, renamed to dzlog.
* Added zlog-gen-conf.
* Controlled rotate count.
* Abandoned ideas:
- [x] Used writev to write logs, improve efficiency, achieve one-time formation, multiple outputs -- writev internally also uses buffer memcpy.
- [x] Tried semaphore method to make it thread-safe for archiving mutual exclusion problems.
- [x] zlog.h variable-length parameter macro problem (refer to glib's log solution).
- [x] dynamic] file in rule can be obtained from format.
- [x] Modified arraylist read length, loop, etc.
- [x] Specified whether to use threads during runtime.
- [x] buf_append optimization -- for safety, did not optimize this.
- [x] Used some automatic compiler and document generator.
- [x] Output to pipes, named pipes same as files.
- [x] Print stack... may need language support.
- [x] zlog-input -c category -p priority -f conf.
- [x] Used fine-grained reo en method to intelligently determine whether to reopen the file with fo en, the operating system itself has done well enough, no need to do.
