Version 1.3.2

  • Add protection against segfault in combination with XDebug < 2.2.7 See xdebug/xdebug#131

Version 1.3.1

  • Improve auto loading/start functionality by using better abstractions from Zend Engine. Replaced copied code from spl_autoload with call to zend_execute_scripts.

  • Bugfix in sql argument summary when FROM keyword was found, but it was not a SELECT/INSERT/UPDATE/DELETE statement.

Version 1.3.0

  • Add support for profiling Event-based frameworks/applications Optionally collect the name of the event triggered as part of the function call for the following libraries:

    • Doctrine 2
    • Zend Framework 2
    • Symfony 2
    • Drupal
    • Wordpress
    • Magento
    • Enlight/Shopware

  • Add optional support to auto start profiling and transmitting to Qafoo Profiler platform by copying QafooProfiler.php next to the qafooprofiler.so.

Version 1.2.2

  • Fix bug in eval() support

Version 1.2.0

  • Fix bug in Smarty support
  • Fix bug in overwrite mechanism of zend_execute for transacation name detection.
  • Improve performance for transaction name detection when no layer data is requested.

Version 1.0

  • Rename extension to qafooprofiler
  • Add support for transaction name detection when not fully profiling (layer-mode)

Version 0.9.11

  • Fix segfault in Twig_Template#getTemplateName instrumentation on PHP versions < 5.5

  • Fix segfault in memory handling of fatal error callback when catching an exception.

  • Fix missing TSRMLS_CC/DC flags and a missing TSRMLS_FETCH() to allow compilation on threaded systems such as Travis running with --enable-zts-maintainer flag.

  • Enabled Travis CI

Version 0.9.10

  • Fix segfault in Twig_Template#getTemplateName instrumentation.

  • Integrate curl dependency into repository cleanly to avoid problems with having to copy the php_curl.h header around.

Version 0.9.9

Version 0.9.8

  • Improve performance on modern CPUs by checking for invariant tsc, a feature that guarantees the same timer values and speed in the cpuinfo register.

    This allows xhprof to avoid the costly bind to a single CPU, which causes performance problems on servers with very high load. Binding to cpus disallows migrating the threads to another cpu and prevents the Kernel to adjust different loads of cpus.

Version 0.9.7

  • Remove xhprof_sample_disable(), use xhprof_disable() instead when in sampling mode.

  • Add xhprof_layers_enable() that accepts an array of key value pairs in the constructor containing function names to layers. Will automatically set the XHPROF_FLAGS_NOUSERLAND mode and use the passed functions as a functions whitelist. The result is a profiling report only based on grouping certain function calls into layers. If you want to profile the request as well, add "main()" => "main()" as an entry.

  • Add new constant XHPROF_FLAGS_NOUSERLAND when set will not override the zend_execute hook for userland functions.

  • Add new function xhprof_last_fatal_error() that returns information on PHP fatal error with trace and more information than PHP core has usually.

    Overrides zend_error_cb such that it will not work when xdebug is also enabled (depends on the order).

Version 0.9.6

  • Add argument_functions feature that allows logging the arguments of a function. Includes special handling for a lot of interesting functions that will want this feature, for example PDO::execute.

Version 0.9.5

  • Fix segfault with PHP 5.5.9 and up
  • Add new option functions to xhprof_enable() that allows whitelist profiling of functions.
