2009-11-21s3: Cache brlock.tdb entries for the fast read&write strict locking code pathVolker Lendecke1-10/+8
For a netbench run this gains around 2% user-space CPU, fetching a 100MB file takes around 4% less.
2009-11-03s3: Remove debug_ctx()Volker Lendecke1-6/+6
smbd just crashed on me: In a debug message I called a routine preparing a string that itself used debug_ctx. The outer routine also used it after the inner routine had returned. It was still referencing the talloc context that the outer debug_ctx() had given us, which the inner DEBUG had already freed.

2009-03-26Fix a scary "fill_share_mode_lock failed" messageVolker Lendecke1-1/+2
To me "fill_share_mode_lock failed" is a "can't happen" alert. There is however a perfectly valid case in get_file_infos() when the file is not open. Change the corresponding debug message to level 10 and explain more.

Jeremy.
2009-02-19s3: Add extid to the dev/inode pairTim Prouty1-3/+3
This extends the file_id struct to add an additional generic uint64_t field: extid. For backwards compatibility with dev/inodes stored in xattr_tdbs and acl_tdbs, the ext id is ignored for these databases. This patch should cause no functional change on systems that don't use SMB_VFS_FILE_ID_CREATE to set the extid. Existing code that uses the smb_share_mode library will need to be updated to be compatibile with the new extid.

2009-02-13Add VFS ops for Windows BRL: Lock, Unlock and Cancel:Zack Kirsch1-33/+48
This patch adds 3 new VFS OPs for Windows byte range locking: BRL_LOCK_WINDOWS, BRL_UNLOCK_WINDOWS and BRL_CANCEL_WINDOWS. Specifically: * I renamed brl_lock_windows, brl_unlock_windows and brl_lock_cancel to *_default as the default implementations of the VFS ops. * The blocking_lock_record (BLR) is now passed into the brl_lock_windows and brl_cancel_windows paths. The Onefs implementation uses it - future implementations may find it useful too. * Created brl_lock_cancel to do what brl_lock/brl_unlock do: set up a lock_struct and call either the Posix or Windows lock function. These happen to be the same for the default implementation. * Added helper functions: increment_current_lock_count() and decrement_current_lock_count(). * Minor spelling correction in brl_timeout_fn: brl -> blr. * Changed blocking_lock_cancel() to return the BLR that it has cancelled. This allows us to assert its the lock that we wanted to cancel. If this assert ever fires, this path will need to take in the BLR to cancel, rather than choosing on its own. * Adds a small helper function: find_blocking_lock_record_by_id(). Used by the OneFS implementation, but could be useful for others.

2008-09-05Write times code update.Jeremy Allison1-5/+28
Ok, here's the fix for the write times breakage with the new tests in S4 smbtorture. The key is keeping in the share mode struct the "old_file_time" as the real write time, set by all the write and allocation calls, and the "changed_write_time" as the "sticky" write time - set by the SET_FILE_TIME calls. We can set them independently (although I kept the optimization of not setting the "old_file_time" is a "changed_write_time" was already set, as we'll never see it. This allows us to update the write time immediately on the SMBwrite truncate case, SET_END_OF_FILE and SET_ALLOCATION_SIZE calls, whilst still have the 2 second delay on the "normal" SMBwrite, SMBwriteX calls. I think in a subsequent patch I'd like to change the name of these from "old_file_time" to "write_time" and "changed_write_time" to "sticky_write_time" to make this clearer. I think I also fixed a bug in Metze's original code in that once a write timestamp had been set from a "normal" SMBwriteX call the fsp->update_write_time_triggered variable was set and then never reset - thus meaning the write timestamp would never get updated again on subsequent SMBwriteX's. The new code checks the update_write_time_event event instead, and doesn't update is there's an event already scheduled. Metze especially, please check this over for your understanding. Jeremy.

2008-04-07locking: store the write time in the locking.tdbStefan Metzmacher1-14/+82
This is needed to implement the strange write time update logic later. We need to store 2 time timestamps to distinguish between the time the file system had before the first client opened the file and a forced timestamp update. metze (This used to be commit 6aaa2ce0eeb46f6735ec984a2e7aadde7a7f456d)

2007-10-10r23183: Check in a change made by Tridge:Volker Lendecke1-51/+35
This replaces the internal explicit dev/ino file id representation by a "struct file_id". This is necessary as cluster file systems and NFS don't necessarily assign the same device number to the shared file system. With this structure in place we can now easily add different schemes to map a file to a unique 64-bit device node. Jeremy, you might note that I did not change the external interface of smb_share_modes.c. Volker (This used to be commit 9b10dbbd5de8813fc15ebbb6be9b18010ffe8139)
