* 1. Fix for elog(ERROR, "EvalPlanQual: t_xmin is uncommitted ?!")Vadim B. Mikheev1999-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and possibly for other cases too: DO NOT cache status of transaction in unknown state (i.e. non-committed and non-aborted ones) Example: T1 reads row updated/inserted by running T2 and cache T2 status. T2 commits. Now T1 reads a row updated by T2 and with HEAP_XMAX_COMMITTED in t_infomask (so cached T2 status is not changed). Now T1 EvalPlanQual gets updated row version without HEAP_XMIN_COMMITTED -> TransactionIdDidCommit(t_xmin) and TransactionIdDidAbort(t_xmin) return FALSE and T2 decides that t_xmin is not committed and gets ERROR above. It's too late to find more smart way to handle such cases and so I just changed xact status caching and got rid TransactionIdFlushCache() from code. Changed: transam.c, xact.c, lmgr.c and transam.h - last three just because of TransactionIdFlushCache() is removed. 2. heapam.c: T1 marked a row for update. T2 waits for T1 commit/abort. T1 commits. T3 updates the row before T2 locks row page. Now T2 sees that new row t_xmax is different from xact id (T1) T2 was waiting for. Old code did Assert here. New one goes to HeapTupleSatisfiesUpdate. Obvious changes too. 3. Added Assert to vacuum.c 4. bufmgr.c: break Assert(buf->r_locks == 0 && !buf->ri_lock) into two Asserts.

| | | | | | | 2. Much faster btree tuples deletion in the case when first on page index tuple is deleted (no movement to the left page(s)). 3. Remember blkno of new root page in BTPageOpaque of left/right siblings when root page is splitted.
* From: Tatsuo Ishii <t-ishii@sra.co.jp>Marc G. Fournier1999-02-21
| | | | | | Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef NOT_USED" for current. I have tested these patches in that the postgres binaries are identical.

| | | | | | | | | | | | | | | | [This is a repost - it supercedes the previous one. It fixes the patch so it doesn't bread aix port, plus there's a file missing out of the original post because difforig doesn't pick up new files. It's now attached. peter] This patch brings the JDBC driver up to the current protocol spec. Basically, the backend now tells the driver what authentication scheme to use. The patch also fixes a performance problem with large objects. In the buffer manager, each fastpath call was sending multiple Notifications to the backend (sometimes more data in the form of notifications were being sent than blob data!).
