#21250 [NEW]: echo output is blocked when using system(), exec(), backticks, etc.

From: adam@ripcord.net Operating system: OpenBSD 3.0 PHP version: 4.3.0 PHP Bug Type: Output Control Bug description: echo output is blocked when using system(), exec(), backticks, etc. A script that I have which automates the building of Apache + PHP + ModSSL is showing strange behavior with PHP 4.3.0. This script works fine with 4.2.x (CGI), but as soon as I upgraded to 4.3.0 (CLI), all output from echo is blocked until the commands that I run through my many calls to system() are complete. The new CLI docs say that implicit flush is on by default with the CLI, but when using system(), exec(), or backticks this doesn't seem to be the case. My apologies if this is mere user stupidity. -- Edit bug report at http://bugs.php.net/?id=21250&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=21250&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=21250&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=21250&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=21250&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=21250&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=21250&r=support Expected behavior: http://bugs.php.net/fix.php?id=21250&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=21250&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=21250&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=21250&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=21250&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=21250&r=dst IIS Stability: http://bugs.php.net/fix.php?id=21250&r=isapi
