Description of XHProf 0.9.4 library/viewer import into Moodle
Removed (commit #1):
* .arcconfig - Definitions for arcanist/phabricator removed completely
* composer.json - Composer's definition removed completely
* examples - examples dir removed completely
* extension - extension dir removed completely
* package.xml - PECL package definition removed completely
* xhprof_html/docs - documentation dir removed completely
Added (commit #2 - always taken from current moodle.git master):
* index.html - prevent directory browsing on misconfigured servers
* xhprof_moodle.php - containing all the stuff needed to run the xhprof profiler within Moodle
* readme_moodle.txt - this file ;-)
Our changes: Look for "moodle" in code (commit #3 - always mimic from current moodle.git master):
* xhprof_html/index.php ----|
* xhprof_html/callgraph.php -|=> Changed to use own DB iXHProfRuns implementation (moodle_xhprofrun)
* xhprof_html/typeahead.php -|
* xhprof_html/css/xhprof.css: Minor tweaks to report styles
* xhprof_lib/utils/callgraph_utils.php: Modified to use $CFG->pathtodot
* xhprof_lib/utils/xhprof_runs.php: applied patch from https://github.com/phacility/xhprof/pull/99
TODO:
* improvements to the listing mode: various commodity details like:
- allow to filter by various criteria
- inline (and ajax) editing of reference/comment and deleting
- whatever daily usage discovers ;-)
* add new settings to control if we want to profile things like:
- php functions
- memory
- cpu times
(all them are right now enabled for everybody by default)
* allow multiple runs to be exported together (right now only ONE can be
exported at a time). Note it is only an UI restriction, backend supports multiple.
