Have you ever spent a ridiculous amount of time on a problem while knowing that you alone must be doing something wrong because of the lack of anyone else having your issue anywhere on the interwebs?
I think this falls into that category.
Problem: I am trying to execute an external call to phantomjs from a php script. When the command or the php script are ran from the command line, it works like a newly oiled engine. When the php script is called from a browser, phantomjs crashes.
I have downloaded both the 32-bit and 64-bit latest versions (1.8.2) to verify it was not simply a problem with either on the DH server.
The test command is:
“2>&1” is appended to the end when called from the php script to display errors.
The PHP test script is simply:
$cmd = "/home/myusername/my.com/manual/phantomjs /home/myusername/my.com/manual/hello.js 2>&1";
1) When the test command is called directly from the command line, it works perfectly.
2) When the php script is called from the command line (php php.test), it works perfectly.
3) When the php script is navigated to from the browser, I get:
PhantomJS has crashed. Please read the crash reporting guide at https://github.com/ariya/phantomjs/wiki/Crash-Reporting and file a bug report at https://code.google.com/p/phantomjs/issues/entry with the crash dump file attached: /tmp/1c144cf0-b85b-6cd1-3a8c927e-105e8f54.dmp
Intriguing facet: If the command for simply requesting the version number is called (phantomjs -v), all three types of calls work.
I have tried the following in attempting to figure out the cause:
- Redownloaded the binaries
- Set the permissions to 777 for all files and directories involved.
- Used both relative and absolute paths.
- Verified through exec(“whoiam”) that it is indeed using my primary user.
- Turned off Extra Web Security and FastCGI
- Sacrificed to multiple deities.
This fine young person had a different problem when trying to do the same, but it's worth noting: https://discussion.dreamhost.com/thread-137268.html?highlight=phantomjs
I would be happy, or even quite ecstatic, if you could offer any help about what I am clearly, and probably foolishly, doing wrong. Thanks!
