#40047 [Opn->Bgs]: stream_eof() return code ignored

ID: 40047 Updated by: iliaa@php.net Reported By: alex at kiesel dot name -Status: Open +Status: Bogus Bug Type: Streams related Operating System: Gentoo Linux PHP Version: 5.2.0 New Comment: It is not possible to eliminate those read calls, sorry. Previous Comments: ------------------------------------------------------------------------ [2007-01-15 17:35:33] alex at kiesel dot name Sorry, it really doesn't matter what stream_eof() returns; subsequent calls to stream_read() are being done regardless of its return value. Removing the function isn't possible as it is a required stream function. Due to performance reasons, one might want to save those calls to stream_eof() (or the last stream_read() call), though. ------------------------------------------------------------------------ [2007-01-07 18:21:42] iliaa@php.net The return value of the function is most definitely not ignored. The internal streams IO requires the additional read, hence the 2nd call. ------------------------------------------------------------------------ [2007-01-07 13:01:44] alex at kiesel dot name Description: ------------ When reading through a stream wrapper, the method stream_eof() is called, but it's result is discarded and ignored. This leads to an obsolete call to stream_read(). Reproduce code: --------------- http://kiesel.name/php/stream.phps Expected result: ---------------- string(11) "stream_stat" string(43) "stream_read(8192) / 80 / returning 80 bytes" string(14) "stream_eof(): " bool(true) Actual result: -------------- string(11) "stream_stat" string(43) "stream_read(8192) / 80 / returning 80 bytes" string(14) "stream_eof(): " bool(true) string(42) "stream_read(8192) / 80 / returning 0 bytes" string(14) "stream_eof(): " bool(true) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40047&edit=1
