2009-07-01Ensure we don't use delayed writes on POSIX opened files.Jeremy Allison1-0/+10
Don't remove pending writetime changes if no time changes are sent in UNIX_BASIC infolevel. Jeremy
2009-06-24s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTATTim Prouty1-1/+1
This patch introduces two new temporary helper functions vfs_stat_smb_fname and vfs_lstat_smb_fname. They basically allowed me to call the new smb_filename version of stat, while avoiding plumbing it through callers that are still too inconvenient. As the conversion moves along, I will be able to remove callers of this, with the goal being to remove all callers. There was also a bug in create_synthetic_smb_fname_split (also a temporary utility function) that caused it to incorrectly handle filenames with ':'s in them when in posix mode. This is now fixed.
2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-1/+1
This patch introduces struct stat_ex { dev_t st_ex_dev; ino_t st_ex_ino; mode_t st_ex_mode; nlink_t st_ex_nlink; uid_t st_ex_uid; gid_t st_ex_gid; dev_t st_ex_rdev; off_t st_ex_size; struct timespec st_ex_atime; struct timespec st_ex_mtime; struct timespec st_ex_ctime; struct timespec st_ex_btime; /* birthtime */ blksize_t st_ex_blksize; blkcnt_t st_ex_blocks; }; typedef struct stat_ex SMB_STRUCT_STAT; It is really large because due to the friendly libc headers playing macro tricks with fields like st_ino, so I renamed them to st_ex_xxx. Why this change? To support birthtime, we already have quite a few #ifdef's at places where it does not really belong. With a stat struct that we control, we can consolidate the nanosecond timestamps and the birthtime deep in the VFS stat calls. At this moment it is triggered by a request to support the birthtime field for GPFS. GPFS does not extend the system level struct stat, but instead has a separate call that gets us the additional information beyond posix. Without being able to do that within the VFS stat calls, that support would have to be scattered around the main smbd code. It will very likely break all the onefs modules, but I think the changes will be reasonably easy to do.
2009-03-01Only copy sharename up from rap_to_pjobidVolker Lendecke1-2/+1
Why?? :-) Another one of the little micro-optimizations that I just came across: If you allocate a variable in a sub-block like the "fstring sharename" in write_file(), gcc even with -O3 will allocate this variable unconditionally on the stack at the beginning of the routine. So with eliminating this fstring we cut 256 bytes of stack in a very hot code path writing to a file. It might make us a bit more cache-friendly. This would probably not be worth a second look if it involved larger code changes, but this one was just too simple to let it pass :-)
2009-02-09s3 oplocks: Make the level2 oplock contention API more granularTim Prouty1-1/+3
This replaces release_level2_oplocks_on_change with contend_level2_oplock_begin/end in order to contend level2 oplocks throughout an operation rather than just at the begining. This is necessary for some kernel oplock implementations, and also lays the groundwork for better correctness in Samba's standard level2 oplock handling. The next step for non-kernel oplocks is to add additional state to the share mode lock struct that prevents any new opens from granting oplocks while a contending operation is in progress. All operations that contend level 2 oplocks are now correctly spanned except for aio and synchronous writes. The two write paths both have non-trivial error paths that need extra care to get right. RAW-OPLOCK and the rest of 'make test' are still passing with this change.

2008-09-08smbd: some write time fixesStefan Metzmacher1-8/+7
- only the first non truncating write causes the write time update with 2 seconds delay. It's not enough to check for an existing update event as it will be NULL after the event was triggered. - SMBwrite truncates always update the write time unless the sticky write time is set. - SMBwrite truncates don't trigger a write time update on close. metze (This used to be commit 3d17089b6dc773303c8c553f3f6140e60e348fb7)
2008-09-05Write times code update.Jeremy Allison1-8/+39
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.

2008-04-07smbd: implement the strange write time update logicStefan Metzmacher1-22/+38
We now never call file_ntimes() directly, every update is done via smb_set_file_time(). This let samba3 pass the BASE-DELAYWRITE test. The write time is only updated 2 seconds after the first write() on any open handle to the current time (not the time of the first write). Each handle which had write requests updates the write time to the current time on close(). If the write time is set explicit via setfileinfo or setpathinfo the write time is visible directly and a following close on the same handle doesn't update the write time. metze (This used to be commit 2eab212ea2e1bfd8fa716c2c89b2c042f7ba12ea)

2007-10-10r21714: Change the VFS interface to use struct timespecJeremy Allison1-2/+2
for utimes - change the call to ntimes. This preserves nsec timestamps we get from stat (if the system supports it) and only maps back down to usec or sec resolution on time set. Looks bigger than it is as I had to move lots of internal code from using time_t and struct utimebuf to struct timespec. Jeremy. (This used to be commit 8f3d530c5a748ea90f42ed8fbe68ae92178d4875)
