* Corrected rule.c, capped path_buf.
-- [Hardy Simpson] <hardysimpson1984@gmail.com>
zlog (1.1.1) unstable; urgency=medium

-- [Hardy Simpson] <hardysimpson1984@gmail.com>

* Automatic configuration refresh based on log count.
* Automatic sync to disk based on log count.
-- [Hardy Simpson] <hardysimpson1984@gmail.com>
zlog (1.0.2) unstable; urgency=medium
* Added synchronous write to disk option (time-consuming when open).
-- [Hardy Simpson] <hardysimpson1984@gmail.com>
zlog (1.0.1) unstable; urgency=medium
* Used configuration file as lock file.
-- [Hardy Simpson] <hardysimpson1984@gmail.com>
zlog (1.0.0) unstable; urgency=medium
* Changed configuration file layout.
* Made reload atomic, falling back to old on failure.
* Optimized spec_gen_msg using custom buf_append alignment.
* Introduced __func__.
* Set file permissions.
* Customizable output function.
-- [Hardy Simpson] <hardysimpson1984@gmail.com>
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.
* Resolved microsecond/millisecond representation in configuration.
* Merged event into thread to avoid memory allocation.
* Added init API for reading configuration files.
* Parsed default format when initialized without configuration, wrote zlog_chk_conf.
* Isolated category.
* Added update API.
* Adjusted buf size dynamically through zlog_init, rebuilt all caches using zlog_update.
* Aligned file creation permissions similar to fopen (0666 & (~umask)).
* 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.
