#49084 [Opn->Fbk]: PSFS_FEED_ME causes stream block

ID: 49084 Updated by: jani@php.net Reported By: morrisdavidd at gmail dot com -Status: Open +Status: Feedback Bug Type: Streams related Operating System: Linux/Unix PHP Version: 5.3.0 New Comment: Can you please provide reproducing scripts that actually give the expected output with the "goodFilter" ?? And fyi, with non-blocking you should use fread() instead of fgets().. Previous Comments: ------------------------------------------------------------------------ [2009-07-28 06:08:58] morrisdavidd at gmail dot com Actual result is when leaving "badFilter".) ------------------------------------------------------------------------ [2009-07-28 06:07:22] morrisdavidd at gmail dot com Description: ------------ According to: http://us3.php.net/manual/en/function.stream-filter-register.php The return value of PSFS_FEED_ME for the method filter of extended classes of php_user_filter means: "Filter processed successfully, however no data was available to return. More data is required from the stream or prior filter." However, using the return value of PSFS_FEED_ME also inadvertently causes a block on stream read requests that should not be blocked (and an infinite poll for data?).
