Tom Lane	499abb0c0f	Implement new 'lightweight lock manager' that's intermediate between ... existing lock manager and spinlocks: it understands exclusive vs shared lock but has few other fancy features. Replace most uses of spinlocks with lightweight locks. All remaining uses of spinlocks have very short lock hold times (a few dozen instructions), so tweak spinlock backoff code to work efficiently given this assumption. All per my proposal on pghackers 26-Sep-01.	24 years ago
Tom Lane	55432fedd2	Implement LockBufferForCleanup(), which will allow concurrent VACUUM ... to wait until it's safe to remove tuples and compact free space in a shared buffer page. Miscellaneous small code cleanups in bufmgr, too.	24 years ago
Bruce Momjian	623bf843d2	Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group.	25 years ago
Tom Lane	680b7357ce	Rearrange bufmgr header files so that buf_internals.h need not be ... included by everything that includes bufmgr.h --- it's supposed to be internals, after all, not part of the API! This fixes the conflict against FreeBSD headers reported by Rosenman, by making it unnecessary for s_lock.h to be included by plperl.c.	25 years ago
Tom Lane	1f6d8b90b8	Buffer manager modifications to keep a local buffer-dirtied bit as well ... as a shared dirtybit for each shared buffer. The shared dirtybit still controls writing the buffer, but the local bit controls whether we need to fsync the buffer's file. This arrangement fixes a bug that allowed some required fsyncs to be missed, and should improve performance as well. For more info see my post of same date on pghackers.	26 years ago
Bruce Momjian	5c25d60244	Add: ... * Portions Copyright (c) 1996-2000, PostgreSQL, Inc to all files copyright Regents of Berkeley. Man, that's a lot of files.	26 years ago
Tom Lane	e812458b27	Several changes here, not very related but touching some of the same files. ... * Buffer refcount cleanup (per my "progress report" to pghackers, 9/22). * Add links to backend PROC structs to sinval's array of per-backend info, and use these links for routines that need to check the state of all backends (rather than the slow, complicated search of the ShmemIndex hashtable that was used before). Add databaseOID to PROC structs. * Use this to implement an interlock that prevents DESTROY DATABASE of a database containing running backends. (It's a little tricky to prevent a concurrently-starting backend from getting in there, since the new backend is not able to lock anything at the time it tries to look up its database in pg_database. My solution is to recheck that the DB is OK at the end of InitPostgres. It may not be a 100% solution, but it's a lot better than no interlock at all...) * In ALTER TABLE RENAME, flush buffers for the relation before doing the rename of the physical files, to ensure we don't get failures later from mdblindwrt(). * Update TRUNCATE patch so that it actually compiles against current sources :-(. You should do "make clean all" after pulling these changes.	26 years ago
