(And if you can, provide a summary why it was wrong and how you fixed it). ------------------------------------------------------------------------ [2005-05-15 02:34:02] joe at bs0 dot com as short as I can make it: <?php $toWrite = 'test string'; $shm_len = strlen($toWrite); $shm_id = shmop_open(0xff3, "c", 0644, $shm_len); shmop_write($shm_id, $toWrite, 0); shmop_close($shm_id); $shm_id = shmop_open(0xff3, "a", 0, 0); $data = shmop_read($shm_id, 0, $shm_len); shmop_close($shm_id); $shm_id = shmop_open(0xff3, "w", 0, 0); if (!shmop_delete($shm_id)) { echo "Couldn't mark shared memory block for deletion.<br/>"; } else { echo "shared memory block marked for deletion.<br/>"; } shmop_close($shm_id); echo 'block closed.<br/>'; $shm_id = shmop_open(0xff3, "a", 0, 0); if($shm_id) { $data = shmop_read($shm_id, 0, $shm_len); shmop_close($shm_id); echo 'ERROR: Previously deleted block able to be opened.<br/>'; echo 'Data read : "' . $data . '"'; } else { echo 'Could not open previously deleted block.<br/>'; } ?> ------------------------------------------------------------------------ [2005-05-12 04:33:53] joe at bs0 dot com Description: ------------ Tested with iis/php5.0.4, iis/php4.3.11, apache2/php4.3.11 - same problem. after a succesful call to shmop_delete, the shared memory can still be opened, and the previous values read in. Delete call seems to have no effect. Each step is done in new request: 1)Create shared memory block, populate with string. 2)open block, read in string 3)open block, call shmop_delete (returns true) 4)open block, read in string <- should not be able to open block for reading at this point. looks to be the same as Bug #28965, this bug has status of No Feedback, so opening a new one. Reproduce code: --------------- Code to reproduce: http://bs0.com/shmop/shmop_test.php.txt Expected result: ---------------- leave only one step uncommented at a time, at step 4, the open should fail and no data should be read in. Actual result: -------------- After step 4, memory is still opened/data is read in. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33011&edit=1
