Edit report at https://bugs.php.net/bug.php?id=66932&edit=1 ID: 66932 Updated by: mike@php.net Reported by: ezzatron at gmail dot com Summary: User stream filter errors cannot be handled -Status: Open +Status: Not a bug Type: Bug Package: Streams related Operating System: OS X 10.9.2 PHP Version: 5.5.10 Block user comment: N Private report: N New Comment: fwrite() only returns FALSE on invalid params. A return value of 0 is pretty indicative of a failure to me. Previous Comments: ------------------------------------------------------------------------ [2014-03-19 11:09:17] ezzatron at gmail dot com Description: ------------ The constant PSFS_ERR_FATAL used to indicate an error condition in a user stream filter has no effect on the return value of relevant stream functions, and there is no alternative way to detect these errors. Test script: --------------- <?php class FatalFilter extends php_user_filter { function filter($in, $out, &$consumed, $closing) { $bucket = stream_bucket_make_writeable($in); return PSFS_ERR_FATAL; } } stream_filter_register('fatal', 'FatalFilter'); $stream = fopen('php://memory', 'wb'); stream_filter_append($stream, 'fatal'); var_dump(fwrite($stream, 'foobar')); fclose($stream); Expected result: ---------------- bool(false) Actual result: -------------- int(0) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66932&edit=1
