Tom Lane	532a4c3531	Be a little more careful with the shift computations in QT2QTN and makeTSQuerySign. The first of these is a live bug, on some platforms, as per bug #5590 from John Regehr. However the consequences seem limited because of the relatively narrow scope of use of QTNode.sign. The shift in makeTSQuerySign is actually safe because TSQS_SIGLEN is unsigned, but it seems like a good idea to insert an explicit cast rather than depend on that.	16 years ago
Tom Lane	57641a165f	Fix core dump in QTNodeCompare when tsquery_cmp() is applied to two empty tsqueries. CompareTSQ has to have a guard for the case rather than blindly applying QTNodeCompare to random data past the end of the datums. Also, change QTNodeCompare to be a little less trusting: use an actual test rather than just Assert'ing that the input is sane. Problem encountered while investigating another issue (I saw a core dump in autoanalyze on a table containing multiple empty tsquery values). Back-patch to all branches with tsquery support. In HEAD, also fix some bizarre (though not outright wrong) coding in tsq_mcontains().	16 years ago

Peter Eisentraut	de160e2c00	Make backend header files C++ safe This alters various incidental uses of C++ key words to use other similar identifiers, so that a C++ compiler won't choke outright. You still (probably) need extern "C" { }; around the inclusion of backend headers. based on a patch by Kurt Harriman <harriman@acm.org> Also add a script cpluspluscheck to check for C++ compatibility in the future. As of right now, this passes without error for me.	17 years ago

Tom Lane	e6dbcb72fa	Extend GIN to support partial-match searches, and extend tsquery to support prefix matching using this facility. Teodor Sigaev and Oleg Bartunov	18 years ago
Bruce Momjian	9098ab9e32	Update copyrights in source tree to 2008.	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	12f25e70a6	Fix two-argument form of ts_rewrite() so it actually works for cases where a later rewrite rule should change a subtree modified by an earlier one. Per my gripe of a few days ago.	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	8983852e34	Improving various checks by Heikki Linnakangas <heikki@enterprisedb.com> - add code to check that the query tree is well-formed. It was indeed possible to send malformed queries in binary mode, which produced all kinds of strange results. - make the left-field a uint32. There's no reason to arbitrarily limit it to 16-bits, and it won't increase the disk/memory footprint either now that QueryOperator and QueryOperand are separate structs. - add check_stack_depth() call to all recursive functions I found. Some of them might have a natural limit so that you can't force arbitrarily deep recursions, but check_stack_depth() is cheap enough that seems best to just stick it into anything that might be a problem.	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
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
Bruce Momjian	436a2956d8	Re-run pgindent, fixing a problem where comment lines after a blank comment line where output as too long, and update typedefs for /lib directory. Also fix case where identifiers were used as variable names in the backend, but as typedefs in ecpg (favor the backend for indenting). Backpatch to 8.1.X.	20 years ago
Teodor Sigaev	0645663e6c	New features for tsearch2: 1 Comparison operation for tsquery 2 Btree index on tsquery 3 numnode(tsquery) - returns 'length' of tsquery 4 tsquery @ tsquery, tsquery ~ tsquery - contains, contained for tsquery. Note: They don't gurantee exact result, only MAY BE, so it useful only for speed up rewrite functions 5 GiST index support for @,~ 6 rewrite(): select rewrite(orig, what, to); select rewrite(ARRAY[orig, what, to]) from tsquery_table; select rewrite(orig, 'select what, to from tsquery_table;'); 7 significantly improve cover algorithm	20 years ago
