I thought Blackfire.io would be able to handle POST the way Xdebug does: Generate a different cachegrind file for every PHP invocation; but alas, Blackfire.io currently only does static webpages, command line, or API calls. In theory I could have used “Copy-As-cURL in your Browser” (and believe me I tried) but in practice the WordPress admin is stateless (no $_SESSION), uses check_admin_referer() all over, making whatever POST action I was copying as cURL useless.
My solution was the following hack:
blackfire run wp eval-file --url=http://pressbooks.dev/helloworld/ test.php
The profiler data gave some bogus results (Ie. a lot of WP-CLI bootstrapping gets flagged as slow) but at least this was better than nothing.
In the future, it would be great if Blackfire Companion had some sort of option to profile “the next action,” or to “start profiler on submit,” or something other than reloading the current page… Ping SensioLabs?
cwRsync is a standalone version of rsync for Windows that doesn’t require Cygwin to be installed. I don’t have Cygwin installed because Git For Windows includes Git Bash and this is “good enough.” With a regular standalone cwRsync installation Cygwin will never be in the PATH and Vagrant will never add the required /cygdrive prefix.
Add C:Program Files (x86)cwRsync(or wherever you installed) to your path. To avoid problems make sure this string is placed beforeC:Program FilesGitcmd and/or C:Program FilesGitmingw64bin;C:Program FilesGitusrbin
Add the following system variable: CYGWIN = nodosfilewarning
Git for Windows is based on MinGw. cwRsync is based on Cygwin. You cannot run Vagrant & cwRsync from Git Bash because cwRsync includes it’s own incompatible SSH binary. If you try you will get the following error:
rsync error: error in rsync protocol data stream (code 12) at io.c(226) [Receive r=3.1.0]
Instead, when launching Vagrant use Microsoft PowerShell.
