Bug #60483 [NEW]: stream_select only selects STDIN if present in read array

From: Operating system: Linux/Debian x64 PHP version: 5.3.8 Package: Streams related Bug Type: Bug Bug description:stream_select only selects STDIN if present in read array Description: ------------ I'm writing a data multiplexer PHP CLI script that takes data from STDIN and dispatchs those data on programs opened with proc_open(). I'm using stream_select() to see which descriptor has data. The read array I'm using contains STDIN and the output streams from programs opened with proc_open() (the classic $pipes[1] from proc_open() descriptorspec). Those programs write on their stdout as soon as there is data on their stdin (actually those programs are PHP scripts echoing input). If STDIN remains in the read set, stream_select returns only STDIN as readable and never returns any of the programs output streams. As soon as STDIN is removed from the read set, stream_select behave normaly and selects the output streams that are ready. Expected result: ---------------- I'm expecting all my ready streams to be returned, even if STDIN is present in the set. -- Edit bug report at https://bugs.php.net/bug.php?id=60483&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=60483&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=60483&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=60483&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=60483&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=60483&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=60483&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=60483&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=60483&r=needscript Try newer version: https://bugs.php.net/fix.php?id=60483&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=60483&r=support Expected behavior: https://bugs.php.net/fix.php?id=60483&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=60483&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=60483&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=60483&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=60483&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=60483&r=dst IIS Stability: https://bugs.php.net/fix.php?id=60483&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=60483&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=60483&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=60483&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=60483&r=mysqlcfg
