2002-11-13Add new palloc0 call as merge of palloc and MemSet(0).Bruce Momjian
2002-11-11Back out use of palloc0 in place if palloc/MemSet. Seems constant lenBruce Momjian
to MemSet is a performance boost.
2002-11-10Merge palloc()/MemSet(0) calls into a single palloc0() call.Bruce Momjian

2002-08-25Clean up comments to be careful about the distinction between variable-Tom Lane
width types and varlena types, since with the introduction of CSTRING as a more-or-less-real type, these concepts aren't identical. I've tried to use varlena consistently to denote datatypes with typlen = -1, ie, they have a length word and are potentially TOASTable; while the term variable width covers both varlena and cstring (and, perhaps, someday other types with other rules for computing the actual width). No code changes in this commit except for renaming a couple macros.
2002-08-24The cstring datatype can now be copied, passed around, etc. The typlenTom Lane
value '-2' is used to indicate a variable-width type whose width is computed as strlen(datum)+1. Everything that looks at typlen is updated except for array support, which Joe Conway is working on; at the moment it wouldn't work to try to create an array of cstring.

2002-05-20Restructure indexscan API (index_beginscan, index_getnext) perTom Lane
yesterday's proposal to pghackers. Also remove unnecessary parameters to heap_beginscan, heap_rescan. I modified pg_proc.h to reflect the new numbers of parameters for the AM interface routines, but did not force an initdb because nothing actually looks at those fields.

tests pass.
2001-03-22Remove dashes in comments that don't need them, rewrap with pgindent.Bruce Momjian
2001-03-22pgindent run. Make it all clean.Bruce Momjian
2001-02-22Clean up index/btree comments/macros, as approved.Bruce Momjian
2001-02-15Although we can't support out-of-line TOAST storage in indexes (yet),Tom Lane
compressed storage works perfectly well. Might as well have a coherent strategy for applying it, rather than the haphazard store-what-you-get approach that was in the code before. The strategy I've set up here is to attempt compression of any compressible index value exceeding BLCKSZ/16, or about 500 bytes by default.

2000-12-27Fix portability problems recently exposed by regression tests on Alphas.Tom Lane
1. Distinguish cases where a Datum representing a tuple datatype is an OID from cases where it is a pointer to TupleTableSlot, and make sure we use the right typlen in each case. 2. Make fetchatt() and related code support 8-byte by-value datatypes on machines where Datum is 8 bytes. Centralize knowledge of the available by-value datatype sizes in two macros in tupmacs.h, so that this will be easier if we ever have to do it again.
2000-12-07Silence compiler warning.Tom Lane
2000-11-30Remove VARLENA_FIXED_SIZE hack, which is irreversibly broken now thatTom Lane
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.
2000-11-16Make pgsql compile on FreeBSD-alpha.Bruce Momjian
Context diff this time. Remove -m486 compile args for FreeBSD-i386, compile -O2 on i386. Compile with only -O on alpha for codegen safety. Make the port use the TEST_AND_SET for alpha and i386 on FreeBSD. Fix a lot of bogus string formats for outputting pointers (cast to int and %u/%x replaced with no cast and %p), and 'Size'(size_t) are now cast to 'unsigned long' and output with %lu/ Remove an unused variable.
