Edit report at https://bugs.php.net/bug.php?id=60483&edit=1 ID: 60483 Updated by: cataphract@php.net Reported by: vmiszczak at ankama dot com Summary: stream_select only selects STDIN if present in read array -Status: Open +Status: Feedback Type: Bug Package: Streams related Operating System: Linux/Debian x64 PHP Version: 5.3.8 Block user comment: N Private report: N New Comment: Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report.

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 this bug report at https://bugs.php.net/bug.php?id=60483&edit=1
