#42720 [NEW]: fread timeout with available datas

From: Slig at free dot fr Operating system: linux PHP version: 4CVS-2007-09-21 (snap) PHP Bug Type: Streams related Bug description: fread timeout with available datas Description: ------------ Seems to be on all 5.2, 6 snap, on 32 bits and 64 bits linux. Note the delay of the last read : it make a 60s timeout while it should not because datas are available to read. Reading data with a bigger length value or setting a small timeout time on the stream show that the data is available immediatly, this timeout shouyld not happen. It seems to happen only to the last read, when all readable datas where not read in one shot. Reproduce code: --------------- <?php $handle = fsockopen('tcp://smtp',25); //stream_set_timeout($handle,0,1); while(!feof($handle)) { $r = array($handle); $w = null; $e = array($handle); $nb = stream_select($r,$w,$e,3); echo "select : $nb, r=".count($r).', w='.count($w).', e='.count($e)."\n"; while($nb>0){ echo "Reading...\n"; $time = microtime(true); $contents = fread($handle,30); $delay = sprintf("%0.6f",(microtime(true)-$time)); echo "Contents(delay:$delay): [$contents]\n"; $r = array($handle); $w = null; $e = array($handle); $nb = stream_select($r,$w,$e,3); echo "select : $nb, r=".count($r).', w='.count($w).', e='.count($e)."\n"; } usleep(20000); } fclose($handle); ?> Expected result: ---------------- select : 1, r=1, w=0, e=0 Reading...
