Since the above is now closed, I am creating this entry. Please accept my apologies if it would have been better added to 22072 instead. I wasn't aware of this potential problem until I saw it in the change log for 4.3.3, so I thought I'd test it. Something is still not right. I'm using PHP 4.3.3 with Apache 2.0.47. My first test was to see whether ignore_user_abort() works as expected. I used the very simple: ignore_user_abort ( false ); while ( 1 ); This makes it easy to spot in the process list using 'top'. I tested both using PHP as a dynamically loaded Apache module and the CGI binary. The latter had safe mode enabled, the former didn't; I don't know whether this can/should make any difference. In both cases the script continued to execute after I clicked on the browser's stop button and until its PHP enforced time limit was reached. I then went on to test ( using only the Apache module ) using the code suggested in bug report 22072: http://www.mpfreescene.com/test/?option=source As rather expected now, this continued to execute after I'd used the stop button. I went on to test by modifying the code as follows: - I set set_time_limit(15); so it would eventually be aborted by this limit. - I made $m very large. - Have the result of connection_status() written to a file each time round the loop. - I removed the sleep() call. I ran the script and used the stop button while it was running. It continued to execute until it had used 15 seconds of CPU time. Log file shows: httpd: PHP Fatal error: Maximum execution time of 15 seconds exceeded in... The final ( large ) output file contained all zeros and a final 2. So, it seems that PHP correctly detects and reports the case of a timeout, but not an abort. I noticed one other possibly odd thing while doing this. If PHP has output buffering enabled, the call to flush() results in the script being immediately shut down ( execution doesn't get to the line following flush() ). The result of connection_status() when called in exitfp() is then 1. If the flush() call is removed, the results as previously described are the same whether or not output buffering is enabled. I hope someone can make sense of all this! Do let me know if you would like any further information. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25266&edit=1
