Only for DUPFIXED DBs. Still could do better.

28b8aaeb96 Add mdb_cursor_txn() and mdb_cursor_dbi() for querying the cursor 2011-10-02 19:28:33 -07:00
Howard Chu
6e05ca17e9 Add MDB_RESERVE mode 
When putting a record, just make space for the data, don't copy it.
(Not compatible with MDB_DUPSORT, since the actual data is needed
to determine the insert location.)

619e671f1c txn_abort/commit free all their cursors now. 2011-09-21 16:37:29 -07:00

b9d13a29e6 Track changes to all cursors. 
For any change to a page or node, update all other cursors pointing
at the same page (or node). Cursors are now stored in a linked list
off their owning transaction. Cursors are all closed when the transaction
ends. Cursors in parent transactions are updated when their child
transaction commits.

57b5fbea49 Add mdb_drop() for deleting a DB 
Allow MIDLs to grow arbitrarily, to allow unlimited number of
pages to be freed in one txn.

09006ccec7 API change, consistency check 
mdb_close() takes an env, not a txn.
Also, add check for stale DB records (in case some other process
wrote to the DB last).

90ed553301 mdb integer type cleanup: Use MDB_dbi consistently. 
This changes the prototype of mdb_env_set_maxdbs().

bf9d722bec mdb type cleanup: Consistent reader count types. 
Use unsigned int for reader counts/max limits, that's the smallest
change.  Don't need uint32_t when mdb_env_set_maxreaders() takes less.
Change prototypes of mdb_env_set_maxreaders,mdb_env_get_maxreaders().
Check the mdb_env_set_maxreaders() argument.

60550e14ee Add some legalese 
Note derived from Martin Hedenfalk's btree.c; the code
is significantly reworked but owes a lot to the original.
