Please let me disagree : 20828 is about a bug of new locking scheme with nfs 20858 is not bogus nor a duplicate : letting dba_open managing lock by default BREAK current scripts : If db was meant to be opened read only (by all httpd process) and filesystem have appropiate rights for that (read only), automatic locking will fail (and dba_open too by the way) I have undestand that by adding the new "-" flag, it will behave as previous release. But why breaking BC ?? By enabling it you may fix existing bugged php script but you may also break working ones. I think it would be better to fix bugged scripts by adding a "l" or "d" and keep BC. Christophe.

I decided to have locking as default to force users to think about locking. Even when you can access a db file only in read mode by php locking is required if any other process may access that file in write mode. Further more dba is a superset of db and db was considered to always lock a db file (even though this is done wrong). And i will look at the NFS part later today or tomorrow. marcus

New Comment: Please do not submit the same bug more than once. An existing bug report already describes this very problem. Even if you feel that your issue is somewhat different, the resolution is likely to be the same. Because of this, we hope you add your comments to the existing bug instead. Thank you for your interest in PHP. Previous Comments: ------------------------------------------------------------------------ [2002-12-09 12:08:10] helly@php.net I added '-' modifier for that now. And marked this one duplicate. See bug 20828 for more. ------------------------------------------------------------------------ [2002-12-07 09:11:03] helly@php.net This was intended and the documentation is bad on this. 'l' and 'd' are only to force one of the two. Maybe i'll add a new modifier to skip locking... ------------------------------------------------------------------------ [2002-12-06 08:57:30] csollet@coleebris.com Already reported in comment on #20828. I make a separate bug report since it's another bug. Opening a db with <? dba_open("E.db", "r", "db2"); ?> create a lock file (note that the "l" attribute is not used) This script will fail on a ro directory! ------------------------------------------------------------------------
