* s3: Fix trans2 path to use case-insensitive stat optimizationtprouty2009-05-051-2/+6
| | | | | | | | | | | | | | | | | | | | Often times before creating a file, a client will first query to see if it already exists. Since some systems have a case-insensitive stat that is called from unix_convert, we can definitively return STATUS_NO_SUCH_FILE to the client without scanning the whole directory. This code path is taken from trans2querypathinfo, but trans2findfirst still does a full directory scan even though the get_real_filename (the case-insensitive stat vfs call) can prevent this. This patch adds the get_real_filename call to the trans2find* path, and also changes the vfs_default behavior for SMB_VFS_GET_REAL_FILENAME. Previously, in the absence of a get_real_filename implementation, we would fallback to the full directory scan. The default behavior now returns -1 and sets errno to EOPNOTSUPP. This allows SMB_VFS_GET_REALFILENAME to be called from trans2* and unix_convert.

* s3:onefs.so fix issue with missing entries when enumerating directoriesSteven Danneman2009-05-041-130/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug prompted several, fairly large changes to the of OneFS's readdirplus() within Samba. One fundamental problem is that we kept our cache cursor pointed at the next entry to be returned from onefs_readdir(), while the resume cookie needed to refill the cache such that our cursor would be on this entry, was located in the previous cache entry. This meant that to correctly handle seekdir() cases which could be found within the existing cache, and cases where a cache reload was needed, required that the cache always hold at least two entries: the entry we wished to return, and the previous entry which held the resume cookie. Since the readdirplus() syscall gives us no guarantee that it will always return these two direntries, there was a fundamental problem with this design. To fix this problem, I have rearchitected the onefs_readdir() path to keep its pointer on the entry which contains the resume_cookie, not the entry which will be returned next. Essentially, I changed onefs_readdir() from a "return an entry then increment the cursor" model to "increment the cursor then return an entry". By doing this, we only require that a single entry be within the cache: the entry containing the resume cookie. Second, there have been numerous off-by-one bugs in my implementation of onefs_seekdir() which did a mapping between the 64-bit resume cookie returned by readdirplus() and its own monotonically increasing "location" offset. Furthermore, this design caused a somewhat frequent waste of cycles, as in some cases we'd need to re-enumerate the entire directory to recover the current "location" from an old resume cookie. As this code was somewhat difficult to understand, prone to bugs, and innefficient in some cases I decided it was better to wholesale replace it now, rather than later. It is possible to algorithmically map the 64-bit resume cookies from readdirplus() into 32-bit offset values which SMB requires. The onefs.so module now calls into a system library to do this conversion. This greatly simplifies both the seekdir() and telldir() paths and is more efficient.
* Fix annoying debug messages when no snapshots are usedVolker Lendecke2009-04-281-2/+3
| | | | | | | Not being able to open the shadow copy directory is the same as having no shadow copy support at all. The VFS module should in this case not log with debug level 0 and set ENOSYS to indicate "no shadow copies used" to the higher levels.

* s3: OneFS implementation of change notifySteven Danneman2009-02-203-0/+691
| | | | | | | | | | | | | | | The OneFS Samba implementation of change notify is modeled after the usage of Linux's inotify kernel subsystem. A single call is made into the onefs.so VFS module to initialize kernel tracking of certain file change events. When these events occur a kernel notification is sent to smbd and the notification event is translated and given to the general Samba Change Notify layer through a callback function. The most difficult aspect is converting an SMB CompletionFilter to a matching ifs_event mask, and then back to an appropriate change notify action. Currently, not all possible cases are handled by the this module, but the most prevalent ones, which are tested by smbtorture, are implemented.
