* Modify heap_open()/heap_openr() API per pghackers discussion of 11 July.Tom Lane2000-08-03
| | | | | | | | | 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 :-(.
* More functions updated to new fmgr style --- money, name, tid datatypes.Tom Lane2000-08-03
| | | | | We're reaching the mopup stage here (good thing too, this is getting tedious).
* bpchar, varchar, bytea, numeric are toastable --- if you initdb, whichTom Lane2000-07-29
| | | | | | I did not force. I marked numeric as compressable-but-not-move-off-able, partly to test that storage mode and partly because I've got doubts that numerics are large enough to need external storage.
* Clean up memory-context stuff, other minor infelicities.Tom Lane2000-07-03

* Use a private memory context to store rule information in each relcacheTom Lane2000-06-30
| | | | | | | | | | | | | | entry that has rules. This allows us to release the rule parsetrees on relcache flush without needing a working freeObject() routine. Formerly, the rule trees were leaked permanently at relcache flush. Also, clean up handling of rule creation and deletion --- there was not sufficient locking of the relation being modified, and there was no reliable notification of other backends that a relcache reload was needed. Also, clean up relcache.c code so that scans of system tables needed to load a relcache entry are done in the caller's memory context, not in CacheMemoryContext. This prevents any un-pfreed memory from those scans from becoming a permanent memory leak.
* First phase of memory management rewrite (see backend/utils/mmgr/READMETom Lane2000-06-28
| | | | | | | | | | | | | 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.

| | | | | | | key call sites are changed, but most called functions are still oldstyle. An exception is that the PL managers are updated (so, for example, NULL handling now behaves as expected in plperl and plpgsql functions). NOTE initdb is forced due to added column in pg_proc.

* Fix problems seen in parallel regress tests when SI buffer overruns (causingTom Lane2000-01-31
| | | | | | | | | | | | | | | | | | | | | | | syscache and relcache flushes). Relcache entry rebuild now preserves original tupledesc, rewrite rules, and triggers if possible, so that pointers to these things remain valid --- if these things change while relcache entry has positive refcount, we elog(ERROR) to avoid later crash. Arrange for xact-local rels to be rebuilt when an SI inval message is seen for them, so that they are updated by CommandCounterIncrement the same as regular rels. (This is useful because of Hiroshi's recent changes to process our own SI messages at CommandCounterIncrement time.) This allows simplification of some routines that previously hacked around the lack of an automatic update. catcache now keeps its own copy of tupledesc for its relation, rather than depending on the relcache's copy; this avoids needing to reinitialize catcache during a cache flush, which saves some cycles and eliminates nasty circularity problems that occur if a cache flush happens while trying to initialize a catcache. Eliminate a number of permanent memory leaks that used to happen during catcache or relcache flush; not least of which was that catcache never freed any cached tuples! (Rule parsetree storage is still leaked, however; will fix that separately.) Nothing done yet about code that uses tuples retrieved by SearchSysCache for longer than is safe.

* Mega-commit to make heap_open/heap_openr/heap_close take anTom Lane1999-09-18
| | | | | | | | | | | | | | | | | 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.
