2007-10-10r21722: Add the dead record functionality presented on ↵Volker Lendecke1-0/+1
samba-technical@samba.org. If you do a tdb_set_max_dead(tdb, n), then for this tdb a delete operation will only mark a record as dead and re-use it if a new record is created. The parameter n allows for at most n dead records per hash chain. If this number is exceeded, all dead records are put on the central freelist.

call which does a read lock on all chains. These will be used to make ldb searches more efficient (This used to be commit de664ec1f8cf179f1d650563272c0de3f7636e2b)

isolation of our portability environment from the main code, and also simplifies the includes system (no separate #ifdef _SAMBA_BUILD for tdb. ldb etc now) (This used to be commit 77d1a468e06290aba789e2f3affc769fc5159a21)

2007-10-10r16916: Implement metze's proposed changes to the tdb logging API.Andrew Bartlett1-3/+2
This clearly links the log function with its private pointer, and makes the argument list for tdb_open_ex a bit shorter. Andrew Bartlett (This used to be commit 5d5503e8d8a10ead3ef21a5ffda52cadb9a07727)
2007-10-10r16774: This patch modifies the tdb API to allow the logging function to be usedAndrew Bartlett1-1/+2
as part of ldb. This allows tdb failures to be passed all the way up to Samba's DEBUG system, which allowed easier debugging. Unfortunately I had to extend the tdb API, as the logging function didn't have a context pointer. I've worked over the 'debug levels' in TDB. Most of them were 0, which didn't seem right, as some were trace-like messages. We didn't see any of these previously, except when accessing TDB directly. Andrew Bartlett (This used to be commit 58898092c1ce043f6d698db5065f372b79109e22)
2007-10-10r14799: added a tdb_get_seqnum() call, and the TDB_SEQNUM flag. This allowsAndrew Tridgell1-1/+3

2007-10-10r10421: following on discussions with simo, I have worked out a way ofAndrew Tridgell1-0/+1
allowing searches to proceed while another process is in a transaction, then only upgrading the transaction lock to a write lock on commit. The solution is: - split tdb_traverse() into two calls, called tdb_traverse() and tdb_traverse_read(). The _read() version only gets read locks, and will fail any write operations made in the callback from the traverse. - the normal tdb_traverse() call allows for read or write operations in the callback, but gets the transaction lock, preventing transastions from starting inside the traverse In addition we enforce the following rule that you may not start a transaction within a traverse callback, although you can start a traverse within a transaction With these rules in place I believe all the deadlock possibilities are removed, and we can now allow for searches to happen in parallel with transactions (This used to be commit 7dd31288a701d772e45b1960ac4ce4cc1be782ed)
2007-10-10r10405: added transactions into tdb, and hook them into ldb. See myAndrew Tridgell1-12/+35
samba-technical posting for more details on the transactions design. This also adds a number of command line arguments to tdbtorture, making it more flexible, and fixes some lock deadlock conditions in the tdbtorture code. (This used to be commit 06bd8abba942ec9f1e23f5c5d546cbb71ca3a701)
2007-10-10r10253: a fairly large tdb cleanup and re-organise. Nearly all of this changeAndrew Tridgell1-0/+208
just involves splitting up the core tdb.c code into separate files on logical boundaries, but there are some minor functional changes as well: - move the 'struct tdb_context' into tdb_private.h, hiding it from users. This was done to allow the structure to change without breaking code that uses tdb. - added accessor functions tdb_fd(), tdb_name(), and tdb_log_fn() to access the elements of struct tdb_context that were used by external code but are no longer visible - simplied tdb_append() to use tdb_fetch()/tdb_store(), which is just as good due to the way tdb locks work - changed some of the types (such as tdb_off to tdb_off_t) to make syntax highlighting work better - removed the old optional spinlock code. It was a bad idea. - fixed a bug in tdb_reopen_all() that caused tdbtorture to sometimes fail or report nasty looking errors. This is the only real bug fixed in this commit. Jeremy/Jerry, you might like to pickup this change for Samba3, as that could definately affect smbd in Samba3. The aim of all of these changes is to make the tdb transactions/journaling code I am working on easier to write. I started to write it on top of the existing tdb.c code and it got very messy. Splitting up the code makes it much easier to follow. There are more cleanups we could do in tdb, such as using uint32_t instead of u32 (suggested by metze). I'll leave those for another day.
