= Feature of XCache =

 * Optimized opcode cache. [http://pecl.php.net/apc apc], [http://www.eaccelerator.net eaccelerator] are also good opcode caches.
 * Using a generator to produce C code, reduces human mistake greatly.
 * Running stable on PHP_4_3/PHP_4_4/PHP_5_1/PHP_5_2
 * Supported and tested on all lastest php cvs branches, such as PHP_4_3 PHP_4_4 ~~PHP_5_0~~ PHP_5_1 PHP_5_2 HEAD (6.x)
 * Alpha supported for in-alpha-php6, with unicode enabled.
 * Readonly Cacher Protection that prevents the cache from being corrupted by php-core/extension or any code other than XCache itself.
 * Atomic [wiki:XcacheApi get/set/inc/dec api] operation on var cache for php programmers.
 * XCache Uptime statistics collector (enabled by server admin), shows you how stable each XCache version is on each php version. [TODO#1]
 * Self sanity test at build time, discover C struct changes within the php script engine. catch up with new php version easier. see [http://blog.lighttpd.net/articles/2006/04/04/one-more-opcache-for-php-preview#comment-214 a real life example] (notice the message 18, 19)
 * Automatically disables itself if the cache is corrupted [TODO#2]
 * Optimizer [TODO]
 * Encoder/Decoder(Loader) [TODO]
 * Disassembler. See how your php script is compiled into opcode. (not with enterprise encoder)
 * Decompiler. decompile opcode into php code. (only half working, and not for enterprise encoder)
 * Coverager + real life testcase framework, this include: [TOSHARE]
   * real life testcase framework, a control script with real browser. you have to write the test cases.
   * builtin Coverager + its viewer from web, to see how much script you have tested.
 * the testcase+Coverager just help you make sure all real life php web applications is running correctly when
   * after enabling XCache
   * after upgrading php4 to php5
   * after upgrading php4/5 to php6
 * Administrator Script
   * view statistics
   * to see if it's AutoDisableOnCorrupted [TODO]
   * view cached php/variable list
   * clear cache
 * Late Class Inherit works just fine. see [http://forum.lighttpd.net/topic/864 one of the feedbacks]

Terms:
 * [TODO]: It's in my TODO list
 * [TOSHARE]: It's already done, but it takes sometime for me to put it into [wiki:GettingSource XCache Source Repo].
