[PHP] exec command fails in php, works in the command line
I have two programs on two servers, and they both have similar problems. In each one, I use 'exec' to call a helper program. In one case, it is ecasound, which I use to resample an mp3. In the other, it is convert, which creates a thumbnail of a very large image the user has uploaded. In both cases, the exec command fails. Not all the time, but some times. In both cases, the command that is being called by exec will work fine at the command line. I assume that there is some memory / resource limit that is being breached when this happens, but I don't know what it is, or how to tell php to allow my programs to run.

Re: [PHP] exec command fails in php, works in the command line
I don't want to crowd the list up with dead ends, so I was trying to respond only to you. I'm not calling a php program from exec, I'm calling ecasound and convert. For example, in the php code: exec(convert $internalpath/$filename -resize {$thumbWidth}x{$thumbHeight} $internalpath/$thumbname, $out, $err); doesn't always work, but with variables substituted on the command line: bash:~ convert futon.jpg -resize 240x180 futon_thumb.jpg will always work. The same is true, on a different server, of my exec that calls ecasound, an mp3 processing utility. Both of these could conceivably use a lot of resources, which is why I think php is killing them off some of the time. On Wed, 21 Sep 2005, John Nichel wrote: Please reply to the list.

Re: [PHP] exec command fails in php, works in the command line
If the web server didn't have permission to execute the app, it would NEVER execute the app, not execute it some of the time. In fact, it ALWAYS executes the app, it just doesn't always allow it to finish. I log all attempts to run these apps in order to debug, so I know that the command as passed from php will work in the command line. I copy and paste the command from the log and it runs, even though it didn't complete execution when called from php. I have increased several parameters in php.ini, including memory limit and allowed execution time. Nothing has helped. The only thing that helps is if I wrap the app I want to run in a perl script and call the perl script from php. That works more of the time, though it still often breaks.

Re: [PHP] exec command fails in php, works in the command line
timeout isn't being used on either of these machines, and as far as I read it, the timeout directive would make the web server fail, producing an apache error or some strange behaviour on the client end. Neither of these happens, the php script completes normally, but the exec command (and only these exec commands, I'm using others in the script that work fine) doesn't always complete. Even if timeout was set to its normal default of 300 seconds, this all happens way before 300 seconds have passed. The whole process takes about 20 or 30 seconds.

Re: [PHP] exec command fails in php, works in the command line
convert doesn't produce any output regardless of whether it works or not. Ecasound produces output when it works, but when it doesn't, it produces no output.

Re: [PHP] exec command fails in php, works in the command line
You're telling me. That's why I think php or apache kills it.

Ecasound produces output when it works, but when it doesn't, it produces no output. Using php tricks to capture standard error also produces no output. Hopefully somebody else on the list can help. Without any output/error messages, it's kind of hard to know what the problem is. -- John C.

Re: [PHP] exec command fails in php, works in the command line
Yes, but that's been done. Since these are shared servers, on one I am logged in as the user the web server is running as, on the other I can't su to nobody, but were there permissions errors, I would have been able to capture them. If permissions caused this, it would fail every time, since I'm always writing to the same directory. Instead it only fails some of the time.

Re: [PHP] exec command fails in php, works in the command line
I am assuming that you get hold of the file through uploading it, correct? So, when it fails maybe another upload (i.e. script invocation) is happening and the previous file gets lost/corrupted/whatever. Try to move the file to another dir (maybe /tmp) with a random name and see what happens. Anyway, I think that this kind of thing should really be delegated to a cronjob. -Stathis On Wednesday 21 September 2005 20:45, [EMAIL PROTECTED] wrote: Yes, but that's been done.

Re: [PHP] exec command fails in php, works in the command line
php places uploaded files in the /tmp directory with a unique name, and when I copy them to my directory, I also guarantee a unique name for them. I have verified that this is all working. I've patched this with a cron job that runs every minute, but it really should happen in php, so that the user can get immediate feedback on how the thumbnail looks or how the mp3 file sounds.

Re: [PHP] exec command fails in php, works in the command line
did you tried to run the script from the shell as www-data user ?

yeah, if you look at the thread you will see that I've already done this. On Wed, 21 Sep 2005, adriano ghezzi wrote: did you tried to run the script from the shell as www-data user ?
