2010-09-20Remove cvs keywords from all files.Magnus Hagander
2010-01-10Remove partial, broken support for NULL pointers when fetching attributes.Robert Haas
Previously, fastgetattr() and heap_getattr() tested their fourth argument against a null pointer, but any attempt to use them with a literal-NULL fourth argument evaluated to *(void *)0, resulting in a compiler error. Remove these NULL tests to avoid leading future readers of this code to believe that this has a chance of working. Also clean up related legacy code in nocachegetattr(), heap_getsysattr(), and nocache_index_getattr(). The new coding standard is that any code which calls a getattr-type function or macro which takes an isnull argument MUST pass a valid boolean pointer. Per discussion with Bruce Momjian, Tom Lane, Alvaro Herrera.

2007-11-07Use "alternative" instead of "alternate" where it is clearer.Peter Eisentraut
2007-04-06Support varlena fields with single-byte headers and unaligned storage.Tom Lane
This commit breaks any code that assumes that the mere act of forming a tuple (without writing it to disk) does not "toast" any fields. While all available regression tests pass, I'm not totally sure that we've fixed every nook and cranny, especially in contrib. Greg Stark with some help from Tom Lane
2007-02-27Replace direct assignments to VARATT_SIZEP(x) with SET_VARSIZE(x, len).Tom Lane
Get rid of VARATT_SIZE and VARATT_DATA, which were simply redundant with VARSIZE and VARDATA, and as a consequence almost no code was using the longer names. Rename the length fields of struct varlena and various derived structures to catch anyplace that was accessing them directly; and clean up various places so caught. In itself this patch doesn't change any behavior at all, but it is necessary infrastructure if we hope to play any games with the representation of varlena headers. Greg Stark and Tom Lane

2006-07-14Fix misguided removal of access/tuptoaster.h inclusion, per Kris Jurka.Tom Lane
I'm going to insist on reversion of this entire patch unless pgrminclude is upgraded to a less broken state, but in the meantime let's get contrib passing regression again.

clean up itup.h a little bit.
2005-03-21Convert index-related tuple handling routines from char 'n'/' ' to boolTom Lane
convention for isnull flags. Also, remove the useless InsertIndexResult return struct from index AM aminsert calls --- there is no reason for the caller to know where in the index the tuple was inserted, and we were wasting a palloc cycle per insert to deliver this uninteresting value (plus nontrivial complexity in some AMs). I forced initdb because of the change in the signature of the aminsert routines, even though nothing really looks at those pg_proc entries...

Also performed an initial run through of upgrading our Copyright date to extend to 2005 ... first run here was very simple ... change everything where: grep 1996-2004 && the word 'Copyright' ... scanned through the generated list with 'less' first, and after, to make sure that I only picked up the right entries ...

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.

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.
