Bug #69290 [Opn->Fbk]: Invalid modes do not trigger errors

Edit report at https://bugs.php.net/bug.php?id=69290&edit=1 ID: 69290 Updated by: laruence@php.net Reported by: roborg at gmail dot com Summary: Invalid modes do not trigger errors -Status: Open +Status: Feedback Type: Bug Package: Program Execution Operating System: Windows PHP Version: 5.5.23 Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2015-03-25 09:29:53] laruence@php.net in proc_open: if (strncmp(Z_STRVAL_PP(zmode), "w", 1) != 0) { descriptors[ndesc].parentend = newpipe[1]; descriptors[ndesc].childend = newpipe[0]; descriptors[ndesc].mode |= DESC_PARENT_MODE_WRITE; } else { descriptors[ndesc].parentend = newpipe[0]; descriptors[ndesc].childend = newpipe[1]; } so, it's very clear why no notice was raised(assume "r" by default). considering bc issue, and not very helpful notices.... maybe change to a doc issue is better. ------------------------------------------------------------------------ [2015-03-24 15:52:53] roborg at gmail dot com Description: ------------ Valid modes for pipes are "r" and "w" according to the docs. Though a comment in the docs suggests using "a" for STDERR on Windows, I believe this may be outdated. Modes other than "r" and "w" (and possibly "a"?) should trigger an error, but are silently ignored and the pipe just doesn't work properly. Test script: --------------- $descriptors = array( array('pipe', 'x'), array('pipe', 'y'), array('pipe', 'z'), ); $process = proc_open('ls', $descriptors, $pipes); proc_close($process); Expected result: ---------------- Error: proc_open(): x is not a valid descriptor mode Actual result: -------------- (nothing) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69290&edit=1
