XCache 3.0.0

XCache is a open-source opcode cacher, which means that it accelerates the performance of PHP on servers. It optimizes performance by removing the compilation time of PHP scripts by caching the compiled state of PHP scripts into the shm (RAM) and uses the compiled version straight from the RAM. This will increase the rate of page generation time by up to 5 times as it also optimizes many other aspects of php scripts and reduce serverload. The XCache project is lead by mOo who is also a developer of Lighttpd. Lighttpd is one of the fastest webserver programs and outperforms Apache and many other open source webserving projects so the same is being done to XCache. Feature of XCache

• Optimized opcode cache.  apc,  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 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  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
