Bug description: shmop: can still open segment for reading after shmop_delete
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.
