* Failing to find an entry when doing mod_share_entry isn't a errorJeremy Allison2002-05-211-3/+4

| | | | | | | | | shutdown. I have just helped debug a very large Solaris server where the traversal was taking so long that the clients timed out, created a new process which in turn did a traversal! we will need to find some other way of doing a brlock.tdb cleanup (if its even needed at all)

| | | | | | | | | | | | | | "One of these locks is not like the others... One of these locks is not quite the same" :-). When is a zero timeout lock not zero ? When it's being processed by Windows 2000 of course.. This code change, ugly though it is - completely fixes the foxpro/access multi-user file system database problems that people have been having. I used a *wonderful* test program donated by "Gerald Drouillard" <gerald@drouillard.ca> which allowed me to completely reproduce this problem, and to finally determine the correct fix. This also explains why Windows 2000 is *so slow* when responding to the smbtorture lock tests. I *love* it when all these things come together and finally make sense :-). Jeremy.

* After conversations with Andrew, improved the robustness of theJeremy Allison2001-11-301-26/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | sharemode db in the following way. Originally, on startup and shutdown, smbd would scan the share mode db to ensure it was correct. This lead to scalability issues as scans lock the db for quite a long time. Andrew had the brainstorm that we only care about the record we're about to read. This new code (small change really, but quite significant) causes get_share_modes() to do a process_exists() call against each pid in each record, and to delete any that don't and re-write the entry if any dead records were detected. This allowed me to remove the startup/shutdown scans of the db (they can be added into smbstatus if anyone really cares to have them back). This will please the vfs author who was worried about the time taken on open() calls, and will lead to much greater robustness and scalability in the share mode db. We need much testing of this, and also netbench tests to ensure the extra process_exists() calls don't hurt performance (they shouldn't it's a very simple system call). Jeremy.

* Correct fix for unaligned memcpy - malloc'ed memory incremented by ↵Jeremy Allison2001-09-181-18/+20
| | | | | | | | | | sizeof(struct locking_data) was not forced to be 8 byte aligned. Use union to force it to be correctly aligned for memcpy and use void *, to tell compiler not to optimize aligned copy (this last fix suggested by Trond @ RedHat). The first fix should be sufficient, but this provides a "belt and braces" fix. Jeremy.

* 2nd DELETE_ON_CLOSE_FLAG fix ...Andrew Tridgell2001-09-051-3/+3
| | | | | | | | | | we set the DELETE_ON_CLOSE_FLAG on all share modes on the file, which means the share mode in the fsp will not match the one in the tdb when we come to close for other file handles, which means we end up with share modes on files after all handles are closed fixed by making the comparison function that says if two shares modes are equal ignore the DELETE_ON_CLOSE_FLAG

* started converting NTSTATUS to be a structure on systems with gcc in order ↵Andrew Tridgell2001-08-271-6/+6
| | | | to make it type incompatible with BOOL so we catch errors sooner. This has already found a number of bugs
* converted smbd to use NTSTATUS by defaultAndrew Tridgell2001-08-272-33/+73
| | | | | | | | | | | | | | | | major changes include: - added NSTATUS type - added automatic mapping between dos and nt error codes - changed all ERROR() calls to ERROR_DOS() and many to ERROR_NT() these calls auto-translate to the client error code system - got rid of the cached error code and the writebmpx code We eventually will need to also: - get rid of BOOL, so we don't lose error info - replace all ERROR_DOS() calls with ERROR_NT() calls but that is too much for one night

* This is Jeremy pretending to be Volker, 'cos theVolker Lendecke2001-08-211-64/+136
| | | | | | | | | | | | | | | | | link from Seattle is having problems. I've added 3 things here to work on the fcntl spin problem. 1). Check *all* tdb return codes... :-). 2). If we're asking ourselves to break an oplock, and we can't find a fsp pointer that matches the entry, this is a *logic bug* and we should abort and panic so someone with gdb can pick up the pieces. 3). After we've broken an oplock, ensure that the entry itself has been removed, and if not remove it ourselves. This should not be neccessary in a correctly working environmen,t, but will provide an added layer of robustness in error situations. 4). I hate german keyboards :-) :-). Jeremy.
* Ensure we are very explicit about what we're comparing whenJeremy Allison2001-08-201-4/+4
| | | | | | | we're comparing structures (ie. don't just do a memcmp). I don't think this will fix the fcntl spin issue, but it's a "just in case" change. Jeremy.
