Noah Misch	0b7026d964	Predict integer overflow to avoid buffer overruns. Several functions, mostly type input functions, calculated an allocation size such that the calculation wrapped to a small positive value when arguments implied a sufficiently-large requirement. Writes past the end of the inadvertent small allocation followed shortly thereafter. Coverity identified the path_in() vulnerability; code inspection led to the rest. In passing, add check_stack_depth() to prevent stack overflow in related functions. Back-patch to 8.4 (all supported versions). The non-comment hstore changes touch code that did not exist in 8.4, so that part stops at 9.0. Noah Misch and Heikki Linnakangas, reviewed by Tom Lane. Security: CVE-2014-0064	12 years ago
Robert Haas	32ba2b5160	Use memcmp() rather than strncmp() when shorter string length is known. It appears that this will be faster for all but the shortest strings; at least one some platforms, memcmp() can use word-at-a-time comparisons. Noah Misch, somewhat pared down.	15 years ago
Magnus Hagander	9f2e211386	Remove cvs keywords from all files.	15 years ago

Tom Lane	172eacba43	Assorted improvements in contrib/hstore. Remove the 64K limit on the lengths of keys and values within an hstore. (This changes the on-disk format, but the old format can still be read.) Add support for btree/hash opclasses for hstore --- this is not so much for actual indexing purposes as to allow use of GROUP BY, DISTINCT, etc. Add various other new functions and operators.

Bruce Momjian	d747140279	8.4 pgindent run, with new combined Linux/FreeBSD/MinGW typedef list provided by Andrew.	17 years ago
Teodor Sigaev	3df4fa6968	Fix memory allocation for output of hstore type. Per "maosen.zhang" <maosen.zhang@alibaba-inc.com> report.	17 years ago
Tom Lane	f3a72bd40b	Fix contrib/hstore to throw an error for keys or values that don't fit in its data structure, rather than silently truncating them. Andrew Gierth	17 years ago
Alvaro Herrera	f8c4d7db60	Restructure some header files a bit, in particular heapam.h, by removing some 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.	18 years ago
Tom Lane	9f652d430f	Fix up several contrib modules that were using varlena datatypes in 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.	19 years ago
Neil Conway	d49fa4c866	Fix typos in comments and error messages in HStore. Patch from Filip Rembialkowski, with some additional fixes by myself.	19 years ago
Bruce Momjian	f99a569a2e	pgindent run for 8.2.	19 years ago
Tom Lane	beca984e5f	Fix bugs in plpgsql and ecpg caused by assuming that isspace() would only return true for exactly the characters treated as whitespace by their flex scanners. Per report from Victor Snezhko and subsequent investigation. Also fix a passel of unsafe usages of <ctype.h> functions, that is, ye olde char-vs-unsigned-char issue. I won't miss <ctype.h> when we are finally able to stop using it.	20 years ago
Tom Lane	aab964b311	Fix some uses of str[n]casecmp that should be pg_str[n]casecmp.	20 years ago
Teodor Sigaev	34ec0c81af	Fix compiler warnings on 64-bit boxes: difference between pointers are int64, but warnings are emitted for position info in error messages in parser, so, just cast it to int32	20 years ago
Teodor Sigaev	642194ba0c	Add hstore contrib module. Per discussion http://archives.postgresql.org/pgsql-hackers/2006-08/msg01409.php	20 years ago
