* Stopgap patch for problem with cursors using hash joins: an ABORTTom Lane2000-11-101-1/+7
| | | | | | | | | would cause two attempts to delete the hashtable portal, one from query shutdown and one from portalmem.c. Fix by making hash portals be treated as 'special' portal names, so that CollectNamedPortals will not think it should delete them. This code is in need of complete rewrite (and is already largely rewritten in current sources), but still need to put a finger in the dike for 7.0.*.

| | | | | | | | | | | | | | | | | | | | | | | 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.

* Alter AllocSet routines so that requests larger thanTom Lane1999-08-241-40/+133
| | | | | | | | | | ALLOC_BIGCHUNK_LIMIT are always allocated as separate malloc() blocks, and are free()d immediately upon pfree(). Also, if such a chunk is enlarged with repalloc(), translate the operation into a realloc() so as to minimize memory usage. Of course, these large chunks still get freed automatically if the alloc set is reset. I have set ALLOC_BIGCHUNK_LIMIT at 64K for now, but perhaps another size would be better?

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this one could be useful for people experiencing out-of-memory crashes while executing queries which retrieve or use a very large number of tuples. The problem happens when storage is allocated for functions results used in a large query, for example: select upper(name) from big_table; select big_table.array[1] from big_table; select count(upper(name)) from big_table; This patch is a dirty hack that fixes the out-of-memory problem for the most common cases, like the above ones. It is not the final solution for the problem but it can work for some people, so I'm posting it. The patch should be safe because all changes are under #ifdef. Furthermore the feature can be enabled or disabled at runtime by the `free_tuple_memory' options in the pg_options file. The option is disabled by default and must be explicitly enabled at runtime to have any effect. To enable the patch add the follwing line to Makefile.custom: CUSTOM_COPT += -DFREE_TUPLE_MEMORY To enable the option at runtime add the following line to pg_option: free_tuple_memory=1 Massimo

* Hi,Bruce Momjian1998-04-061-5/+3
| | | | | | | | | | | | | | | | | | | | | | Attached you'll find a (big) patch that fixes make dep and make depend in all Makefiles where I found it to be appropriate. It also removes the dependency in Makefile.global for NAMEDATALEN and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh a little smarter. This no longer requires initdb.sh that is turned into initdb with a sed script when installing Postgres, hence initdb.sh should be renamed to initdb (after the patch has been applied :-) ) This patch is against the 6.3 sources, as it took a while to complete. Please review and apply, Cheers, Jeroen van Vianen

| | | | | | | | | Makefile.global. End result, if all goes well, should allow for much easier porting, since there will no longer be a concept of a "port". Most, if not everything, *should* be determined by configure, or by the compiler itself. Still work to be done though :)
