Teodor Sigaev	a867b40cf4	Fix tsvectorout() and tsqueryout() to escape backslesh, add test of that. Patch by Bruce Momjian <bruce@momjian.us> Backpatch is needed, but it's impossible to apply it directly	18 years ago
Bruce Momjian	f6e8730d11	Re-run pgindent with updated list of typedefs. (Updated README should avoid this problem in the future.)	18 years ago
Bruce Momjian	fdf5a5efb7	pgindent run for 8.3.	18 years ago
Tom Lane	bb36c51fcd	Fix several bugs in tsvectorin, including crash due to uninitialized field and miscomputation of required palloc size. The crash could only occur if the input contained lexemes both with and without positions, which is probably not common in practice. The miscomputation would definitely result in wasted space. Also fix some inconsistent coding around alignment of strings and positions in a tsvector value; these errors could also lead to crashes given mixed with/without position data and a machine that's picky about alignment. And be more careful about checking for overflow of string offsets. Patch is only against HEAD --- I have not looked to see if same bugs are in back-branch contrib/tsearch2 code.	18 years ago
Tom Lane	1ea47dd8cb	Fix shared tsvector/tsquery input code so that we don't say "syntax error in tsvector" when we are really parsing a tsquery. Report the bogus input, too. Make styles of some related error messages more consistent.	18 years ago
Teodor Sigaev	978de9d06d	Improvements from Heikki Linnakangas <heikki@enterprisedb.com> - change the alignment requirement of lexemes in TSVector slightly. Lexeme strings were always padded to 2-byte aligned length to make sure that if there's position array (uint16[]) it has the right alignment. The patch changes that so that the padding is not done when there's no positions. That makes the storage of tsvectors without positions slightly more compact. - added some #include "miscadmin.h" lines I missed in the earlier when I added calls to check_stack_depth(). - Reimplement the send/recv functions, and added a comment above them describing the on-wire format. The CRC is now recalculated in tsquery as well per previous discussion.	19 years ago
Teodor Sigaev	e5be89981f	Refactoring by Heikki Linnakangas <heikki@enterprisedb.com> with small editorization by me - Brake the QueryItem struct into QueryOperator and QueryOperand. Type was really the only common field between them. QueryItem still exists, and is used in the TSQuery struct as before, but it's now a union of the two. Many other changes fell from that, like separation of pushval_asis function into pushValue, pushOperator and pushStop. - Moved some structs that were for internal use only from header files to the right .c-files. - Moved tsvector parser to a new tsvector_parser.c file. Parser code was about half of the size of tsvector.c, it's also used from tsquery.c, and it has some data structures of its own, so it seems better to separate it. Cleaned up the API so that TSVectorParserState is not accessed from outside tsvector_parser.c. - Separated enumerations (#defines, really) used for QueryItem.type field and as return codes from gettoken_query. It was just accidental code sharing. - Removed ParseQueryNode struct used internally by makepol and friends. push*-functions now construct QueryItems directly. - Changed int4 variables to just ints for variables like "i" or "array size", where the storage-size was not significant.	19 years ago

Tom Lane	140d4ebcb4	Tsearch2 functionality migrates to core. The bulk of this work is by Oleg Bartunov and Teodor Sigaev, but I did a lot of editorializing, so anything that's broken is probably my fault. Documentation is nonexistent as yet, but let's land the patch so we can get some portability testing done.	19 years ago
