Bruce Momjian	af74855a60	Renaming cleanup, no pgindent yet.	27 years ago
Bruce Momjian	7971539020	heap_fetch requires buffer pointer, must be released; heap_getnext no longer returns buffer pointer, can be gotten from scan; descriptor; bootstrap can create multi-key indexes; pg_procname index now is multi-key index; oidint2, oidint4, oidname are gone (must be removed from regression tests); use System Cache rather than sequential scan in many places; heap_modifytuple no longer takes buffer parameter; remove unused buffer parameter in a few other functions; oid8 is not index-able; remove some use of single-character variable names; cleanup Buffer variables usage and scan descriptor looping; cleaned up allocation and freeing of tuples; 18k lines of diff;	27 years ago

Marc G. Fournier	4e9dd95296	From: Peter T Mount <patches@maidast.demon.co.uk> [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!).	28 years ago

Marc G. Fournier	159f8c63ad	From: Dan McGuirk <mcguirk@indirect.com> Reply-To: hackers@hub.org, Dan McGuirk <mcguirk@indirect.com> To: hackers@hub.org Subject: [HACKERS] tmin writeback optimization I was doing some profiling of the backend, and noticed that during a certain benchmark I was running somewhere between 30% and 75% of the backend's CPU time was being spent in calls to TransactionIdDidCommit() from HeapTupleSatisfiesNow() or HeapTupleSatisfiesItself() to determine that changed rows' transactions had in fact been committed even though the rows' tmin values had not yet been set. When a query looks at a given row, it needs to figure out whether the transaction that changed the row has been committed and hence it should pay attention to the row, or whether on the other hand the transaction is still in progress or has been aborted and hence the row should be ignored. If a tmin value is set, it is known definitively that the row's transaction has been committed. However, if tmin is not set, the transaction referred to in xmin must be looked up in pg_log, and this is what the backend was spending a lot of time doing during my benchmark. So, implementing a method suggested by Vadim, I created the following patch that, the first time a query finds a committed row whose tmin value is not set, sets it, and marks the buffer where the row is stored as dirty. (It works for tmax, too.) This doesn't result in the boost in real time performance I was hoping for, however it does decrease backend CPU usage by up to two-thirds in certain situations, so it could be rather beneficial in high-concurrency settings.	29 years ago
Marc G. Fournier	37a8bdba43	The second patch adds a more explicative error message to BufferPoolCheckLeak. It should be completely harmless. Submitted by: Massimo Dal Zotto <dz@cs.unitn.it>	29 years ago
Vadim B. Mikheev	9ff69034b2	Fixing possible losing data changes: 1. New flag - BM_JUST_DIRTIED - added for BufferDesc; 2. All data "dirtiers" (WriteBuffer and WriteNoReleaseBuffer) set this flag (and BM_DIRTY too); 3. All data "flushers" (FlushBuffer, BufferSync and BufferReplace) turn this flag off just before calling smgr[blind]write/smgrflush and check this flag after flushing buffer: if it turned ON then BM_DIRTY will stay ON.	29 years ago
Vadim B. Mikheev	eb08b3ce4f	No more LateWrite, but there is WriteMode; SetBufferWriteMode () added; FlushBuffer () fixed: now directly calls smgrflush () and releases buffer only if required by caller.	29 years ago
Vadim B. Mikheev	2ca05fe45d	ReleaseTmpRelBuffers is ReleaseRelationBuffers now.	29 years ago
Vadim B. Mikheev	ae753b86b5	ReleaseTmpRelBuffers () releases buffers in LOCAL buffer pool now (if rd_islocal is true).	29 years ago
