Tom Lane	1f5cc8c78a	Remove VARLENA_FIXED_SIZE hack, which is irreversibly broken now that ... both MULTIBYTE and TOAST prevent char(n) from being truly fixed-size. Simplify and speed up fastgetattr() and index_getattr() macros by eliminating special cases for attnum=1. It's just as fast to handle the first attribute by presetting its attcacheoff to zero; so do that instead when loading the tupledesc in relcache.c.	25 years ago

Tom Lane	3908473c80	Make DROP TABLE rollback-able: postpone physical file delete until commit. ... (WAL logging for this is not done yet, however.) Clean up a number of really crufty things that are no longer needed now that DROP behaves nicely. Make temp table mapper do the right things when drop or rename affecting a temp table is rolled back. Also, remove "relation modified while in use" error check, in favor of locking tables at first reference and holding that lock throughout the statement.	25 years ago

Tom Lane	dd8ad64118	Fix tuptoaster bugs induced by making bytea toastable. Durn thing was ... trying to toast tuples inserted into toast tables! Fix is two-pronged: first, ensure all columns of a toast table are marked attstorage='p', and second, alter the target chunk size so that it's less than the threshold for trying to toast a tuple. (Code tried to do that but the expression was wrong.) A few cosmetic cleanups in tuptoaster too. NOTE: initdb forced due to change in toaster chunk-size.	26 years ago
Tom Lane	61aca818c4	Modify heap_open()/heap_openr() API per pghackers discussion of 11 July. ... These two routines will now ALWAYS elog() on failure, whether you ask for a lock or not. If you really want to get a NULL return on failure, call the new routines heap_open_nofail()/heap_openr_nofail(). By my count there are only about three places that actually want that behavior. There were rather more than three places that were missing the check they needed to make under the old convention :-(.	26 years ago

Peter Eisentraut	385470f8c6	Fixes for Solaris/cc suggested by <pgsql-hackers@thewrittenword.com> ... Don't use DISABLE_COMPLEX_MACRO on Solaris. Don't define the replacement function in the header file. Use -KPIC, not -K PIC. Use CC to link C++ libraries, not ld/ar. Eliminate file not found warnings in tcl build code.	26 years ago
Tom Lane	1aebc3618a	First phase of memory management rewrite (see backend/utils/mmgr/README ... for details). It doesn't really do that much yet, since there are no short-term memory contexts in the executor, but the infrastructure is in place and long-term contexts are handled reasonably. A few long- standing bugs have been fixed, such as 'VACUUM; anything' in a single query string crashing. Also, out-of-memory is now considered a recoverable ERROR, not FATAL. Eliminate a large amount of crufty, now-dead code in and around memory management. Fix problem with holding off SIGTRAP, SIGSEGV, etc in postmaster and backend startup.	26 years ago

Tom Lane	9dab9ab5e4	Repair memory leaks that caused CacheCxt to grow without bound. We ... really ought to fix relcache entry construction so that it does not do so much with CurrentMemoryContext = CacheCxt. As is, relatively harmless leaks in either sequential or index scanning translate to permanent leaks if they occur when called from relcache build. For the moment, however, the path of least resistance is to repair all such leaks...	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.	27 years ago
Tom Lane	bd272cace6	Mega-commit to make heap_open/heap_openr/heap_close take an ... additional argument specifying the kind of lock to acquire/release (or 'NoLock' to do no lock processing). Ensure that all relations are locked with some appropriate lock level before being examined --- this ensures that relevant shared-inval messages have been processed and should prevent problems caused by concurrent VACUUM. Fix several bugs having to do with mismatched increment/decrement of relation ref count and mismatched heap_open/close (which amounts to the same thing). A bogus ref count on a relation doesn't matter much *unless* a SI Inval message happens to arrive at the wrong time, which is probably why we got away with this sloppiness for so long. Repair missing grab of AccessExclusiveLock in DROP TABLE, ALTER/RENAME TABLE, etc, as noted by Hiroshi. Recommend 'make clean all' after pulling this update; I modified the Relation struct layout slightly. Will post further discussion to pghackers list shortly.	27 years ago
