2016-03-08ltree: Zero padding bytes when allocating memory for externally visible data.Andres Freund
ltree/ltree_gist/ltxtquery's headers stores data at MAXALIGN alignment, requiring some padding bytes. So far we left these uninitialized. Zero those by using palloc0. Author: Andres Freund Reported-By: Andres Freund / valgrind / buildarm animal skink Backpatch: 9.1-
2015-05-15Move strategy numbers to include/access/stratnum.hAlvaro Herrera
For upcoming BRIN opclasses, it's convenient to have strategy numbers defined in a single place. Since there's nothing appropriate, create it. The StrategyNumber typedef now lives there, as well as existing strategy numbers for B-trees (from skey.h) and R-tree-and-friends (from gist.h). skey.h is forced to include stratnum.h because of the StrategyNumber typedef, but gist.h is not; extensions that currently rely on gist.h for rtree strategy numbers might need to add a new A few .c files can stop including skey.h and/or gist.h, which is a nice side benefit. Per discussion: https://www.postgresql.org/message-id/20150514232132.GZ2523@alvh.no-ip.org Authored by Emre Hasegeli and Álvaro. (It's not clear to me why bootscanner.l has any #include lines at all.)
2014-04-18Create function prototype as part of PG_FUNCTION_INFO_V1 macroPeter Eisentraut
Because of gcc -Wmissing-prototypes, all functions in dynamically loadable modules must have a separate prototype declaration. This is meant to detect global functions that are not declared in header files, but in cases where the function is called via dfmgr, this is redundant. Besides filling up space with boilerplate, this is a frequent source of compiler warnings in extension modules. We can fix that by creating the function prototype as part of the PG_FUNCTION_INFO_V1 macro, which such modules have to use anyway. That makes the code of modules cleaner, because there is one less place where the entry points have to be listed, and creates an additional check that functions have the right prototype. Remove now redundant prototypes from contrib and other modules.
2012-06-25Replace int2/int4 in C code with int16/int32Peter Eisentraut
The latter was already the dominant use, and it's preferable because in C the convention is that intXX means XX bits. Therefore, allowing mixed use of int2, int4, int8, int16, int32 is obviously confusing. Remove the typedefs for int2 and int4 for now. They don't seem to be widely used outside of the PostgreSQL source tree, and the few uses can probably be cleaned up by the time this ships.
2011-09-11Remove many -Wcast-qual warningsPeter Eisentraut
This addresses only those cases that are easy to fix by adding or moving a const qualifier or removing an unnecessary cast. There are many more complicated cases remaining.
2011-09-01Remove unnecessary #include references, per pgrminclude script.Bruce Momjian
2011-01-09Use array_contains_nulls instead of ARR_HASNULL on user-supplied arrays.Tom Lane
This applies the fix for bug #5784 to remaining places where we wish to reject nulls in user-supplied arrays. In all these places, there's no reason not to allow a null bitmap to be present, so long as none of the current elements are actually null. I did not change some other places where we are looking at system catalog entries or aggregate transition values, as the presence of a null bitmap in such an array would be suspicious.
2010-09-20Remove cvs keywords from all files.Magnus Hagander
2010-02-24Allow zero-dimensional (ie, empty) arrays in contrib/ltree operations.Tom Lane
The main motivation for changing this is bug #4921, in which it's pointed out that it's no longer safe to apply ltree operations to the result of ARRAY(SELECT ...) if the sub-select might return no rows. Before 8.3, the ARRAY() construct would return NULL, which might or might not be helpful but at least it wouldn't result in an error. Now it returns an empty array which results in a failure for no good reason, since the ltree operations are all perfectly capable of dealing with zero-element arrays. As far as I can find, these ltree functions are the only places where zero array dimensionality is rejected unnecessarily. Back-patch to 8.3 to prevent behavioral regression of queries that worked in older releases.

2008-05-17Add $PostgreSQL$ markers to a lot of files that were missing them.Andrew Dunstan
This particular batch was just for *.c and *.h file. The changes were made with the following 2 commands: find . \( \( -name 'libstemmer' -o -name 'expected' -o -name 'ppport.h' \) -prune \) -o \( -name '*.[ch]' \) \( -exec grep -q '\$PostgreSQL' {} \; -o -print \) | while read file ; do head -n 1 < $file | grep -q '^/\*' && echo $file; done | xargs -l sed -i -e '1s/^\// /' -e '1i/*\n * $PostgreSQL:$ \n *' find . \( \( -name 'libstemmer' -o -name 'expected' -o -name 'ppport.h' \) -prune \) -o \( -name '*.[ch]' \) \( -exec grep -q '\$PostgreSQL' {} \; -o -print \) | xargs -l sed -i -e '1i/*\n * $PostgreSQL:$ \n */'
2008-05-12Restructure some header files a bit, in particular heapam.h, by removing someAlvaro Herrera
unnecessary #include lines in it. Also, move some tuple routine prototypes and macros to htup.h, which allows removal of heapam.h inclusion from some .c files. For this to work, a new header file access/sysattr.h needed to be created, initially containing attribute numbers of system columns, for pg_dump usage. While at it, make contrib ltree, intarray and hstore header files more consistent with our header style.
2008-04-14Push index operator lossiness determination down to GIST/GIN opclassTom Lane
"consistent" functions, and remove pg_amop.opreqcheck, as per recent discussion. The main immediate benefit of this is that we no longer need 8.3's ugly hack of requiring @@@ rather than @@ to test weight-using tsquery searches on GIN indexes. In future it should be possible to optimize some other queries better than is done now, by detecting at runtime whether the index match is exact or not. Tom Lane, after an idea of Heikki's, and with some help from Teodor.
2007-11-16Run pgindent on remaining files now that LOOPBYTE is a usable macro.Bruce Momjian
2007-11-16Modify LOOPBYTE/LOOPBIT macros to be more logical; rather than have theBruce Momjian
for() body passed as a parameter, make the macros act as simple headers to code blocks. This allows pgindent to be run on these files.
2007-02-28Fix up several contrib modules that were using varlena datatypes in ↵Tom Lane
not-so-obvious ways. I'm not totally sure that I caught everything, but at least now they pass their regression tests with VARSIZE/SET_VARSIZE defined to reverse byte order.

Thank to Mario Weilguni <mweilguni@sime.com> to discover a bug.
2006-06-28ChangesTeodor Sigaev
* new split algorithm (as proposed in http://archives.postgresql.org/pgsql-hackers/2006-06/msg00254.php) * possible call pickSplit() for second and below columns * add spl_(l|r)datum_exists to GIST_SPLITVEC - pickSplit should check its values to use already defined spl_(l|r)datum for splitting. pickSplit should set spl_(l|r)datum_exists to 'false' (if they was 'true') to signal to caller about using spl_(l|r)datum. * support for old pickSplit(): not very optimal but correct split * remove 'bytes' field from GISTENTRY: in any case size of value is defined by it's type. * split GIST_SPLITVEC to two structures: one for using in picksplit and second - for internal use. * some code refactoring * support of subsplit to rtree opclasses TODO: add support of subsplit to contrib modules
2006-01-20Replace bitwise looping with bytewise looping in hemdistsign andTom Lane
sizebitvec of tsearch2, as well as identical code in several other contrib modules. This provided about a 20X speedup in building a large tsearch2 index ... didn't try to measure its effects for other operations. Thanks to Stephan Vollmer for providing a test case.
2006-01-08Fix the assert_enabled issue properly. This eliminates the former ABITom Lane
difference between USE_ASSERT_CHECKING and not: the assert_enabled variable is always there.
2005-12-06Fix stupid bug with sizeofTeodor Sigaev
2005-11-19Add defenses against nulls-in-arrays to contrib/ltree. Possibly it'dTom Lane
be useful to actually do something with nulls, rather than reject them, but I'll just close the hole for now.
2005-11-07R-tree is dead ... long live GiST.Tom Lane
2005-05-21Cleanup of GiST extensions in contrib/: now that we always invoke GiSTNeil Conway
methods in a short-lived memory context, there is no need for GiST methods to do their own manual (and error-prone) memory management.
2004-10-21Standardize on using the Min, Max, and Abs macros that are in our c.h file,Tom Lane
getting rid of numerous ad-hoc versions that have popped up in various places. Shortens code and avoids conflict with Windows min() and max() macros.

2002-08-26Modify array operations to include array's element type OID in theTom Lane
array header, and to compute sizing and alignment of array elements the same way normal tuple access operations do --- viz, using the tupmacs.h macros att_addlength and att_align. This makes the world safe for arrays of cstrings or intervals, and should make it much easier to write array-type-polymorphic functions; as examples see the cleanups of array_out and contrib/array_iterator. By Joe Conway and Tom Lane.
