ID: 64709 Updated by: a...@php.net Reported by: williama_lovaton at coomeva dot com dot co Summary: Get a PHP stack trace on process signal Status: Open Type: Feature/Change Request Package: Performance problem Operating System: Linux PHP Version: Irrelevant Block user comment: N Private report: N New Comment: With performance - what about profiling with xdebug or zend? The other were for sure possible catching some signal. Though dunno yet if the same gdb functionality is available on windows. Previous Comments: ------------------------------------------------------------------------ [2013-04-25 16:22:02] williama_lovaton at coomeva dot com dot co Description: ------------ I'm not sure if this is possible to implement or if it's implemented now but I'd like a way to get a PHP stack trace of a running process on any given time (may be using a process signal with kill). This would be very similar to what you can do with Java, you do a "kill -3 <pid>" but the process doesn't die, instead it outputs a full backtrace of Java code of every thread and the current state. You can do something similar now using the gstack command from GDB but you'll get a stack trace from the C code. I'd like to be able to get a stack trace but from the PHP code so that I can analyze where is the exact point in the program where my web app is running slow or getting stuck. My web app is instrumented and I can get logs from slow functions but this is information I get after the fact. With this feature request it would be possible to get the information exactly when it is happening. Is this possible? If so, would it be possible to make it work if PHP is being run as an Apache module? Thanks a lot for your time. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64709&edit=1
