* Some changes to prepare for LONG attributes.Jan Wieck1999-12-16

* Rename several destroy* functions/tags to drop*.Bruce Momjian1999-12-10

* Split 'BufFile' routines out of fd.c into a new module, buffile.c. ExtendTom Lane1999-10-13
| | | | | | | | BufFile so that it handles multi-segment temporary files transparently. This allows sorts and hashes to work with data exceeding 2Gig (or whatever the local limit on file size is). Change psort.c to use relative seeks instead of absolute seeks for backwards scanning, so that it won't fail when the data volume exceeds 2Gig.
* Move some system includes into c.h, and remove duplicates.Bruce Momjian1999-07-17

* Remove unused #includes in *.c files.Bruce Momjian1999-07-15

* Rewrite hash join to use simple linked lists instead of aTom Lane1999-05-18
| | | | | | | fixed-size hashtable. This should prevent 'hashtable out of memory' errors, unless you really do run out of memory. Note: target size for hashtable is now taken from -S postmaster switch, not -B, since it is local memory in the backend rather than shared memory.
* Update hash and join routines to use fd.c's new temp-fileTom Lane1999-05-09

* Fix some nasty coredump bugs in hashjoin. This code was justTom Lane1999-05-06
| | | | | | | | | | about certain to fail anytime it decided the relation to be hashed was too big to fit in memory --- the code for 'batching' a series of hashjoins had multiple errors. I've fixed the easier problems. A remaining big problem is that you can get 'hashtable out of memory' if the code's guesstimate about how much overflow space it will need turns out wrong. That will require much more extensive revisions to fix, so I'm committing these fixes now before I start on that problem.
* Fix some more hashjoin-related bugs in pg_operator. FixTom Lane1999-04-07
| | | | | | | hashjoin's hashFunc() so that it does the right thing with pass-by-value data types (the old code would always return 0 for int2 or char values, which would work but would slow things down a lot). Extend opr_sanity regress test to catch more kinds of errors.
* Change my-function-name-- to my_function_name, and optimizer renames.Bruce Momjian1999-02-13

* Cleanup of source files where 'return' or 'var =' is alone on a line.Bruce Momjian1999-02-03

* Apply Win32 patch from Horak Daniel.Bruce Momjian1999-01-17

* Initial MVCC code.Vadim B. Mikheev1998-12-15
| | | | New code for locking buffer' context.
* more cleanups...of note, appendStringInfo now performs like sprintf(),Marc G. Fournier1998-12-14
| | | | | | | | | | where you state a format and arguments. the old behavior required each appendStringInfo to have to have a sprintf() before it if any formatting was required. Also shortened several instances where there were multiple appendStringInfo() calls in a row, doing nothing more then adding one more word to the String, instead of doing them all in one call.
* Many more cleanups...Marc G. Fournier1998-12-14

* Initial attempt to clean up the code...Marc G. Fournier1998-12-14
| | | | | | Switch sprintf() to snprintf() Remove any/all #if 0 -or- #ifdef NOT_USED -or- #ifdef FALSE sections of code
* New HeapTuple structure/interface.Vadim B. Mikheev1998-11-27

* OK, folks, here is the pgindent output.Bruce Momjian1998-09-01

* Renaming cleanup, no pgindent yet.Bruce Momjian1998-09-01
|
* Remove un-needed braces around single statements.Bruce Momjian1998-06-15

* pgindent run before 6.3 release, with Thomas' requested changes.Bruce Momjian1998-02-26
|
* Support for subselects.Vadim B. Mikheev1998-02-13
| | | | | | | ExecReScan for nodeAgg, nodeHash, nodeHashjoin, nodeNestloop and nodeResult. Fixed ExecReScan for nodeMaterial. Get rid of #ifdef INDEXSCAN_PATCH. Get rid of ExecMarkPos and ExecRestrPos in nodeNestloop.

* Some *very* major changes by darrenk@insightdist.com (Darren King)Marc G. Fournier1998-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ========================================== What follows is a set of diffs that cleans up the usage of BLCKSZ. As a side effect, the person compiling the code can change the value of BLCKSZ _at_their_own_risk_. By that, I mean that I've tried it here at 4096 and 16384 with no ill-effects. A value of 4096 _shouldn't_ affect much as far as the kernel/file system goes, but making it bigger than 8192 can have severe consequences if you don't know what you're doing. 16394 worked for me, _BUT_ when I went to 32768 and did an initdb, the SCSI driver broke and the partition that I was running under went to hell in a hand basket. Had to reboot and do a good bit of fsck'ing to fix things up. The patch can be safely applied though. Just leave BLCKSZ = 8192 and everything is as before. It basically only cleans up all of the references to BLCKSZ in the code. If this patch is applied, a comment in the config.h file though above the BLCKSZ define with warning about monkeying around with it would be a good idea. Darren darrenk@insightdist.com (Also cleans up some of the #includes in files referencing BLCKSZ.) ==========================================

| | | | | | | | | | | | | | |This patch fixes a backend crash that happens sometimes when you try to |join on a field that contains NULL in some rows. Postgres tries to |compute a hash value of the field you're joining on, but when the field |is NULL, the pointer it thinks is pointing to the data is really just |pointing to random memory. This forces the hash value of NULL to be 0. | |It seems that nothing matches NULL on joins, even other NULL's (with or |without this patch). Is that what's supposed to happen? |
