|Summary||0000122: Profiling problems with serendipity|
|Description||The cachegrind file that is generated is faulty and contains invalid characters (Ultraedit shows lots of blank lines - but also changes size of scroll bar while scrolling. less shows lots of ^@). Here is an example:|
These files cannot be opened with KCachegrind (on Cygwin; it freezes) nor WinCachegrind (errormsg pointing to the respective line 8565).
This only happens when profiling serendipity ( www.s9y.org ). Other Scripts work fine.
|Additional Information||WindowsXP SP2, Apache 1.3.29, PHP 4.3.10 (not dev).|
|Tags||No tags attached.|
|Operating System||Windows XP|
I get the exact same symptoms, but am trying to profile the SyncML interface to horde (Horde.org). The bad characters it adds are NULL characters (ascii 0) and there are sometimes megabytes of them. I wrote a quick perl script to drop the NULLs out, and the files now load in kcachegrind, but the values are bogus and there are may obvious things wrong with the results.
I have tried both 2.0.0beta2 and also CVS HEAD as of sometime last week.
System: Mandriva 10.0
Horde: CVS Head as of a few weeks ago
This is a show-stopper for me.
||I found the problem for me. It turns out that my SyncML client was making several connections in a row in order to process the request. Since XDebug creates a single file for all requests to the same directory, and since apache is multi-threaded, there were several threads competing to write to the file. I threw in a dirty hack to make it create a new filename on each request and I get several files that are all correct without any NULLs.|
||This is not something I can fix... you can select Xdebug to create a file per-pid ofcourse.|
