* CREATE btree INDEX takes dead tuples into account when old transactionsHiroshi Inoue2000-08-10
| | | | are running.
* Ensure that catcache 'busy' flags are reset at transaction abort.Tom Lane2000-08-06
| | | | | | Without this, an elog during cache-entry load leaves that catcache unusable. elog in that segment of code is pretty unusual but it can happen.
* Fix tuptoaster bugs induced by making bytea toastable. Durn thing wasTom Lane2000-08-04
| | | | | | | | | 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.
* 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).
* Make acl-related functions safe for TOAST. Mark pg_class.relacl asTom Lane2000-07-31
| | | | | compressible but not externally storable (since we're not sure about whether creating a toast relation for pg_class would work).
* Convert all remaining geometric operators to new fmgr style. ThisTom Lane2000-07-30
| | | | | | | | allows fixing problems with operators that expected to be able to return a NULL, such as the '#' line-segment-intersection operator that tried to return NULL when the two segments don't intersect. (See, eg, bug report from 1-Nov-99 on pghackers.) Fix some other bugs in passing, such as backwards comparison in path_distance().
* PATH and POLYGON datatypes are now TOASTable. Associated functionsTom Lane2000-07-29
| | | | | updated to new fmgr style. Deleted hoary old functions for compatibility with pre-6.1 representations of these datatypes.
* Ensure that if the OID counter wraps around, we will not generate 0,Tom Lane2000-07-25
| | | | nor any OID in the reserved range (1-16383).
* Add commentary about varying usage of scankeys in btree code.Tom Lane2000-07-25

* Clean up and document btree code for ordering keys. Neat stuff,Tom Lane2000-07-25
| | | | | | actually, but who could understand it with no comments? Fix bug while at it: _bt_orderkeys would try to invoke comparisons on NULL inputs, given the right sort of redundant quals.

* Further cleanup of btbuild (CREATE INDEX). Avoid storing unneededTom Lane2000-07-21
| | | | | | left keys during bottom-up index build, and leave some free space instead of packing the pages to the brim (so as to avoid vast numbers of page splits during the first interactive insertions).
* Fix sloppiness about alignment requirements in findsplitloc() spaceTom Lane2000-07-21
| | | | | calculation, also make it stop when it has a 'good enough' split instead of exhaustively trying all split points.
* Need to switch to tuples memory context when replacing the toastedJan Wieck2000-07-21

* Temporary fix to make TOAST vacuum-safe. All values are forced to beJan Wieck2000-07-21
| | | | | | | in memory (plain or compressed) in the tuple returned from the heap-am. So no index will ever contain an external reference. Jan
* Major overhaul of btree index code. Eliminate special BTP_CHAIN logic forTom Lane2000-07-21
| | | | | | | | | | | | duplicate keys by letting search go to the left rather than right when an equal key is seen at an upper tree level. Fix poor choice of page split point (leading to insertion failures) that was forced by chaining logic. Don't store leftmost key in non-leaf pages, since it's not necessary. Don't create root page until something is first stored in the index, so an unused index is now 8K not 16K. (Doesn't seem to be as easy to get rid of the metadata page, unfortunately.) Massive cleanup of unreadable code, fix poor, obsolete, and just plain wrong documentation and comments. See src/backend/access/nbtree/README for the gory details.
* Cleanup of code for creating index entries. Functional indexes withTom Lane2000-07-14
| | | | | | | | | | | | | pass-by-ref data types --- eg, an index on lower(textfield) --- no longer leak memory during index creation or update. Clean up a lot of redundant code ... did you know that copy, vacuum, truncate, reindex, extend index, and bootstrap each basically duplicated the main executor's logic for extracting information about an index and preparing index entries? Functional indexes should be a little faster now too, due to removal of repeated function lookups. CREATE INDEX 'opt_type' clause is deimplemented by these changes, but I haven't removed it from the parser yet (need to merge with Thomas' latest change set first).
* Repair parallel make in backend tree (and make it really parallel).Peter Eisentraut2000-07-13
| | | | Make Gen_fmgrtab.sh reasonably robust against concurrent invocation.
* First stage of reclaiming memory in executor by resetting short-termTom Lane2000-07-12
| | | | | | memory contexts. Currently, only leaks in expressions executed as quals or projections are handled. Clean up some old dead cruft in executor while at it --- unused fields in state nodes, that sort of thing.

* Fixes for Solaris/cc suggested by <pgsql-hackers@thewrittenword.com>Peter Eisentraut2000-06-30
| | | | | | | | 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.
* 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.
* Clean up bogosities in pg_opclass, pg_amop, pg_amproc. There are amprocTom Lane2000-06-19
| | | | | | | entries now for int8 and network hash indexes. int24_ops and int42_ops are gone. pg_opclass no longer contains multiple entries claiming to be the default opclass for the same datatype. opr_sanity regress test extended to catch errors like these in the future.
* Reimplement nodeMaterial to use a temporary BufFile (or even memory, if theTom Lane2000-06-18
| | | | | | | | | | materialized tupleset is small enough) instead of a temporary relation. This was something I was thinking of doing anyway for performance, and Jan says he needs it for TOAST because he doesn't want to cope with toasting noname relations. With this change, the 'noname table' support in heap.c is dead code, and I have accordingly removed it. Also clean up 'noname' plan handling in planner --- nonames are either sort or materialize plans, and it seems less confusing to handle them separately under those names.
* Get rid of IndexIsUniqueNoCache() kluge by the simple expedient ofTom Lane2000-06-17
| | | | | | | passing the index-is-unique flag to index build routines (duh! ... why wasn't it done this way to begin with?). Aside from eliminating an eyesore, this should save a few milliseconds in btree index creation because a full scan of pg_index is not needed any more.

* I had overlooked the fact that some fmgr-callable functions return voidTom Lane2000-06-14
| | | | | | --- ie, they're only called for side-effects. Add a PG_RETURN_VOID() macro and use it where appropriate. This probably doesn't change the machine code by a single bit ... it's just for documentation.
* Another batch of fmgr updates. I think I have gotten all old-styleTom Lane2000-06-13

* Latest round of fmgr updates. All functions with bool,char, or int2Tom Lane2000-06-05
| | | | | | | inputs have been converted to newstyle. This should go a long way towards fixing our portability problems with platforms where char and short parameters are passed differently from int-width parameters. Still more to do for the Alpha port however.

* Create an fd.c entry point that is just like plain open(2) except thatTom Lane2000-06-02
| | | | | | | | | | it will close VFDs if necessary to surmount ENFILE or EMFILE failures. Make use of this in md.c, xlog.c, and user.c routines that were formerly vulnerable to these failures. In particular, this should handle failures of mdblindwrt() that have been observed under heavy load conditions. (By golly, every other process on the system may crash after Postgres eats up all the kernel FDs, but Postgres will keep going!)
* The heralded `Grand Unified Configuration scheme' (GUC)Peter Eisentraut2000-05-31
| | | | | | | | | | | | | That means you can now set your options in either or all of $PGDATA/configuration, some postmaster option (--enable-fsync=off), or set a SET command. The list of options is in backend/utils/misc/guc.c, documentation will be written post haste. pg_options is gone, so is that pq_geqo config file. Also removed were backend -K, -Q, and -T options (no longer applicable, although -d0 does the same as -Q). Added to configure an --enable-syslog option. changed all callers from TPRINTF to elog(DEBUG)
* Third round of fmgr updates: eliminate calls using fmgr() andTom Lane2000-05-30
| | | | | fmgr_faddr() in favor of new-style calls. Lots of cleanup of sloppy casts to use XXXGetDatum and DatumGetXXX ...

* Generated header files parse.h and fmgroids.h are now copied intoTom Lane2000-05-29
| | | | | the src/include tree, so that -I backend is no longer necessary anywhere. Also, clean up some bit rot in contrib tree.
