Author	SHA1	Message	Date
Hallvard Furuseth	e4ce404992	More ITS#7589: Fix prev commit. mp_pages gives #pages in the ovpage. OVPAGES() no longer does.	12 years ago
Hallvard Furuseth	0cdd9dffdd	ITS#7589 mdb_cursor_put(): Update ovpage nodesize. Update the nodesize when overwriting an overflow page. As before, do not attempt to shrink the page.	12 years ago
Howard Chu	833cd905b7	Include <netinet/in.h> for Solaris 8 Needed for <resolv.h>, which is needed for BYTE_ORDER.	12 years ago
Howard Chu	7233bc295b	Fix mdb_page_split - nested split If updating a page's separator triggers a split in its parent, we may have missed adjusting the parent's cursor position.	12 years ago
Howard Chu	1105aa35ba	Doxygen cleanup	12 years ago
Howard Chu	9ebd5992c9	Fix `66c839f029` Forgot #include <errno.h>	12 years ago
Howard Chu	66c839f029	Refactor mdb_midl_append, add mdb_midl_grow()	12 years ago
Hallvard Furuseth	2d6aed7537	ITS#7515 Fix nested transaction error handling. mdb_txn_begin(): Do not free(mt_free_pgs), it needs mdb_midl_free(). mdb_txn_commit(): Catch commit(child) error.	12 years ago
Hallvard Furuseth	521fdb00cc	Fix mdb_env_close(unopened MDB_env). Do not try to scan me_dbxs in a closed/never-opened MDB_env. Broken by `7d643d3acb` and `151c416b46`.	12 years ago
Hallvard Furuseth	0b9a208530	Simplify/cleanup mdb_cursor_init, C_ALLOCD. No real change. mdb_cursor_init() checks if it needs mx, so pass it unconditionally. Set C_ALLOCD for shadow cursors, for clarity. (It was always set as it should anyway from the origin cursor, which would have C_ALLOCD.)	12 years ago
Hallvard Furuseth	f355de0298	MDB warning cleanup. Unused function when MDB_DEBUG. Unused 'excl' param.	12 years ago
Hallvard Furuseth	b389341b4b	mdb_dcmp(): Assume the database has MDB_DUPSORT. There was little point in returning EINVAL when not: Comparing (A,B) and (B,A) would claim (A > B && B > A), which could confuse callers.	12 years ago
Hallvard Furuseth	91a93004ce	Update MDB doc: Cursors, DB handles, data lifetime	12 years ago
Hallvard Furuseth	385889b0be	Allow mdb_cursor_close() after readonly txn ends. Catch mdb_cursor_renew(write txn's cursor). Add flag C_UNTRACK, so mdb_cursor_close need not peek inside a possibly-freed readonly txn.	12 years ago
Hallvard Furuseth	17ffe9c992	Close cursors when commit(writer). Factor out code. Close remaining cursors when committing a write txn. The doc says this happens, and it avoids cursor tracking when updating mainDB + freeDB. Rename mdb_cursor_merge() -> mdb_cursors_close() for code reuse, and add a merge option. Simplify its loop a bit. Factor out cleanup of DBIs.	12 years ago
Hallvard Furuseth	dca0cef678	Plug txn leak and MDB_NOTLS slot leaks on error. On mdb_env_copy() error: Abort the txn. On mdb_txn_renew0() error: Release new MDB_NOTLS reader slot.	12 years ago
Hallvard Furuseth	f45d40a88b	Cleaner "Support mdb_txn_abort(a reset txn)". Redo `8a562f560e` so !mt_dbxs indicates "txn was reset", so mt_numdbs gets one magic value instead of two.	12 years ago
Hallvard Furuseth	151c416b46	Update fixes for dbi_open/close, ITS#7515. Reset me_dbflags[dbi] when closing DBI, to get rid of MDB_VALID flag. mdb_env_close(): Re-fix DB-name memleak. DBIs > me_numdbs may exist.	12 years ago
Howard Chu	21da623bf4	Allow reading freelist while working on it The circular dependency issues appear to have been resolved. Still, need to watch closely, maybe revert this change if problems arise.	12 years ago
Howard Chu	568c22c4cc	Avoid assert Due to underfilled branch page. We're in the process of merging/moving nodes to it because we already know it's underfilled. Took this approach rather than just removing the assert in mdb_page_search_root, because that assert may yet catch other situations we don't know about. (Although, it has been there since the original commit of mdb.c and has never triggered any other times...)	12 years ago
Hallvard Furuseth	37bd48a618	Plug mdb_cursor_renew() memleak	12 years ago
Howard Chu	c057582573	Fix MDB_LAST, reset cursor index	12 years ago
Howard Chu	da3e4d78d6	Fix typo from `7aba5f5ab9`	12 years ago
Hallvard Furuseth	9dd61011fe	Tweak comments/readability. Show MDB_PERSISTENT/MDB_VALID/DB_VALID relationship. mdb_txn_renew0(): Remove obsolete "cannot fail" comment.	12 years ago
Howard Chu	272e4e98ad	Add MDB_NOTLS envflag.	12 years ago
Hallvard Furuseth	afe488d8a9	Catch MDB txn reuse/sync errors.	12 years ago
Hallvard Furuseth	8a562f560e	Support mdb_txn_abort(a reset txn).	12 years ago
Hallvard Furuseth	ce6335b0d9	Cleanup for TLS key and read-only filesystem. Move key init into mdb_env_setup_locks(). Don't create unused TLS key when read-only filesystem. Drop internal flag MDB_ROFS, we can instead test either !me_txns, !mt_u.reader or me_lfd==INVALID_HANDLE_VALUE.	12 years ago
Hallvard Furuseth	65a6542765	Clean up MDB_env setup. Malloc before I/O. Avoids possible malloc error after I/O. Don't allocate dirty & free lists when MDB_RDONLY. Factor out code.	12 years ago
Howard Chu	dbb9ded2f8	Fix mdb_rebalance Don't do anything with (fake root) subpages	12 years ago
Howard Chu	aca6c08897	ITS#7574 blind fix Fix `227329c8e1`, don't persist the MDB_VALID bit in db.md_flags.	12 years ago
Howard Chu	92fc932f21	fix prev commit	12 years ago
Howard Chu	0cccf79a02	Fix mdb_rebalance Need to check NUMKEYS as well as fill threshold, when deciding whether to change anything. Don't let the page drop below the minimum number of keys.	12 years ago
Howard Chu	14c5a5dff1	Revert "ITS#7570 fix MDB_GET_MULTIPLE and MDB_NEXT_MULTIPLE" This reverts commit `372b3ddb85`. Original code works as designed.	12 years ago
Claude Brisson	372b3ddb85	ITS#7570 fix MDB_GET_MULTIPLE and MDB_NEXT_MULTIPLE	12 years ago
Howard Chu	fbe6a6051b	Fix `227329c8e1` mdb_dbi_close() must allow any dbi < maxdbs, since opens in an uncommitted txn don't increment env->me_numdbs.	12 years ago
Howard Chu	e43fa77eaa	Revert "Fix 6beaad52129da5353fd40c0ec48e6a78c4f71a2e" This reverts commit `8eef7a4275`. Previous commit was correct, duplicate keys should not appear here.	12 years ago
Howard Chu	227329c8e1	Fixes for dbi_open/close, ITS#7515	12 years ago
Howard Chu	6b46799379	ITS#7561 Fix mdb_drop bugs Check for overflow pages, reset cursor position properly.	12 years ago
Howard Chu	8eef7a4275	Fix `6beaad5212` In APPEND don't immediately reject matching key, since this is valid for APPENDDUP.	12 years ago
Howard Chu	6beaad5212	Fix `d3990eb2f8` Append mode should reject keys that are too small. Also allow APPENDDUP in mdb_put().	12 years ago
Howard Chu	e31d748dbe	Fix rebalance when collapsing root page When fixing other cursors, must also fix their depth.	12 years ago
Howard Chu	cb1cc64831	More fixes for MDB_LAST Make sure C_INITIALIZED gets set on successful call	12 years ago

Howard Chu	0c568117ce	MSVC doesn't define mode_t	12 years ago
