Description:
------------
When I'am locking MySQL ISAM table from PHP env, all other threads
still can use this table for READ/WRITE actions. But I didn't get from
mysql_error() any message, and even cannot access other tables, untill
they not locked too. So it's seems like PHP really thinks that MySQL
locked. I think that this is problem of PHP because from MySQL console
I can lock tables succesfuly, and after this lock even PHP cannot
access this table.
Reproduce code:
---------------
mysql_pconnect("localhost","root","");
mysql_select_db("test_db");
mysql_query("LOCK TABLES `test_table_1` WRITE");
mysql_query("INSERT INTO `test_table_1` (`a`) VALUES (1)"); // returns
OK
mysql_query("INSERT INTO `test_table_2` (`a`) VALUES (1)"); // Table
was not locked with LOCK TABLES
sleep(100);
mysql_query("UNLOCK TABLES");
Expected result:
----------------
with this code I want to show you that all works fine, from side of
thread what lock MySQL table. But really nothing is locked, during this
100 seconds I can edit/read test_table_1, without any problems from
other threads. If I will even remove UNLOCK TABLES command and will use
presistent connection, I will not hang up system. Because nothing is
locked.
Actual result:
--------------
I tried it on PHP v 4.4.0/5.0.3/snapshots, CLI mode/Apache 2.0.54
compiled as worker/prefork, mysql v 4.1.12,13,14. And everywhere the
same picture. I tried to compile PHP in different ways, from
--disable-all + some only important keys, to full configs. Also tried
to use budle MySQL libraries and what install on system. But all the
same.
Hope on your fast bug_fix.
P.S: Also on this system I cannot flock(file) it all the same like with
MySQL, no any error returned, but file no locked for other threads.
