ID: 22238 Updated by: wez@php.net Reported By: wez@php.net Status: Suspended Bug Type: Filesystem function related Operating System: win9x PHP Version: 4CVS-2003-02-15 (stable) Assigned To: wez New Comment: Fixed in php 4.3.2-dev; still needs to be applied to php5. Previous Comments: ------------------------------------------------------------------------ [2003-04-28 19:17:04] wez@php.net Philip has documented this issue; suspending until php5. ------------------------------------------------------------------------ [2003-04-25 05:42:33] wez@php.net I must fix this before 4.3.2 goes gold. ------------------------------------------------------------------------ [2003-02-15 21:57:28] wez@php.net stream_select() causes a buffer synchronization which will clobber the read buffer of any stream that is marked seekable. This behaviour is intended, but under win9x, we cannot always determine if a stream is a FIFO, and this can cause data loss if the buffer size specified in php_stream_read() is ever smaller than the amount of data read in a single read operation (the excess data is lost during the next stream_select() call). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=22238&edit=1
