This allows us to safely commit across multiple tdb databases at once, with reasonable transaction semantics Signed-off-by: tridge@samba.org (This used to be ctdb commit 4c3dac215a088947f645f727343997f5d47e3260)
* New attempt at TDB transaction nesting allow/disallow.Ronnie Sahlberg2009-05-252-1/+14
| | | | | | | | | | Make the default be that transaction is not allowed and any attempt to create a nested transaction will fail with TDB_ERR_NESTING. If an application can cope with transaction nesting and the implicit semantics of tdb_transaction_commit(), it can enable transaction nesting by using the TDB_ALLOW_NESTING flag. (This used to be ctdb commit 3e49e41c21eb8c53084aa8cc7fd3557bdd8eb7b6)
* Revert "add TDB_NO_NESTING. When this flag is set tdb will not allow any ↵Ronnie Sahlberg2009-05-252-15/+4
| | | | | | | | nested transactions and tdb_transaction_start() will implicitely _cancel() any pending transactions before starting any new ones." This reverts commit 459e4ee135bd1cd24c15e5325906eb4ecfd550ec. (This used to be ctdb commit f1c6f7dd47bb1081781c0a0d567a92bbbc0aa5d5)

* second try for safe transaction stores into persistend tdb databasesRonnie Sahlberg2008-05-221-1/+1
| | | | | | for stores into persistent databases, ALWAYS use a lockwait child take out the lock for the record and never the daemon itself. (This used to be ctdb commit 7fb6cf549de1b5e9ac5a3e4483c7591850ea2464)
* dont emit the can not start transaction with locks held at all.Ronnie Sahlberg2008-05-211-1/+1
| | | | | | it just pollutes the logs (This used to be ctdb commit c66e44d44f8d1142394ce5c6a68ac09fd67211fe)
* lower the debug level for the "can not start transaction" since we do expect ↵Ronnie Sahlberg2008-05-211-1/+1
| | | | | | | | this to happen a few times inside ctdb (since we cant really block and wait for all locks to dissapear before we can write the header, for example when doing a dmaster miration) in those cases we accept that we couldnt get a transaction and then just writes the data "unsafely" anyway. (This used to be ctdb commit 56af7df33456bf10d19b97cb005257720ac0b610)
* carefully step around the recovery area when doing a tdb_wipe_all. This preventsAndrew Tridgell2008-02-081-33/+47
| | | | | | problems with wipe_all on databases that may need crash recovery (This used to be ctdb commit e7b1349bf8784c151c2651edd99b3f40ebcece1f)

| | | | (This used to be ctdb commit 21245b894b32f232251fd7c0e2fbfd073fb10514)
* more efficient freelist allocationAndrew Tridgell2008-01-182-43/+43
| | | | | | | | | This takes advantage of the fact that we can do left merges but not right merges By allocating data from the end of the freelist entry rather than the beginning we can guarantee that if we immediately free the record again it will be merged with the previous freelist entry, reducing fragmentation (This used to be ctdb commit 6d159f2c115dd5e9b8bab8798f7ac710b4427593)
* minor fix to transaction_write_existingAndrew Tridgell2008-01-151-16/+6

| | | | | | It was an error in the new transaction code (This used to be ctdb commit 27f0dfdfb93d92859de3cbbd3874cfb38c13a169)
* tdb_freelist_size was reporting 1 more than correct sizeAndrew Tridgell2008-01-101-2/+1
| | | | (This used to be ctdb commit 46214c9234c574b45bce0b88bfb3af437415a69e)
* a compromise for freelist scanning - we now will look for other than the ↵Andrew Tridgell2008-01-091-1/+16
| | | | | | first fit, but get exponentially more desperate as we get deeper into the freelist (This used to be ctdb commit f3319ef84c47dc8bf0bfb4ef1c72cee58ed9d88c)
* added two new ctdb commands:Andrew Tridgell2008-01-082-0/+24
| | | | | | | | | | ctdb vacuum : vacuums all the databases, deleting any zero length ctdb records ctdb repack : repacks all the databases, resulting in a perfectly packed database with no freelist entries (This used to be ctdb commit 3532119c84ab3247051ed6ba21ba3243ae2f6bf4)
* - added tdb_add_flags() and tdb_remove_flags()Andrew Tridgell2008-01-064-3/+17
| | | | | | | | - make freelist merging more paranoid - fixed TDB_DATA_STAART() (broken by earlier commit) (This used to be ctdb commit c3be8eb7d1ca316111ec51f45dbca2fa5609cf93)
* merge from Samba4Andrew Tridgell2008-01-0516-79/+229
| | | | (This used to be ctdb commit 9aed7a1d065272c2e5b54872228a73f37664b526)
* convert tdb from u32 to uint32_t to match the current Samba treesAndrew Tridgell2008-01-057-49/+45
| | | | (This used to be ctdb commit 0dc754b7e8b0985a252885ed043949dfb7ea1ae1)
* Rewrote the tdb transaction code to be O(N) instead of O(N^2)Andrew Tridgell2008-01-051-184/+181
| | | | | | | | | | | | | The previous transaction code was fast as long as you didn't do too many writes within the transaction. The new code is a bit slower for very small numbers of writes, but scales linearly as the number of writes increases. The old code scaled as O(N^2) with the number of writes, making it unusable for large N. After testing, this needs to be merged into the Samba version of tdb, along with many of the other recent tdb changes in the ctdb tree. (This used to be ctdb commit bef8fe3d3ba80c7c660972c5357407f5278f7e26)
