Feature of XCache

• Optimized opcode cacher. ​apc, ​eaccelerator is also good opcode cacher.
• Using C code generator, reduce human mistake.
• Running on PHP_4_3/PHP_4_4 stablly
• Support and tested on all lastest php cvs branches, such as PHP_4_3 PHP_4_4 PHP_5_1 PHP_5_2 HEAD (6.x) (note: 5.0.x is none of them)
• Alpha supported for in-alpha-php6, with unicode enabled.
• Readonly Cacher Protection that prevent the cache from corrupted by php-core/extension code other than XCache itself.
• Atomic get/set/inc/dec api operation on var cache for php programmers.
• A XCache Uptime statistics collector (enable by server admin), show you how stable each XCache version is on each php version. [TODO#1]
• Self sane test at build time, discover c struct changes within php script engine. catch up with new php version easier. see ​a real life example (notice the message 18, 19)
• Auto disable itself if the cache is corrupted [TODO#2]
• Optimizer [TODO]
• Encoder/Decoder?(Loader) [TODO]
• Disassembler. to 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 (in repo) + its visualizer 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 ​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 XCache Source Repo.
