| | | | | Fully update git head, and update back branches in ./COPYRIGHT and legal.sgml files.

* Add const qualifiers where they are accidentally cast awayPeter Eisentraut2012-02-28
| | | | | This only produces warnings under -Wcast-qual, but it's more correct and consistent in any case.

* Be a little more careful with the shift computations in QT2QTN andTom Lane2010-08-03
| | | | | | | | 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.
* Fix core dump in QTNodeCompare when tsquery_cmp() is applied to two emptyTom Lane2010-08-03
| | | | | | | | | | | | | | 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().

* Make backend header files C++ safePeter Eisentraut2009-07-16
| | | | | | | | | | | 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.

* Improvements from Heikki Linnakangas <heikki@enterprisedb.com>Teodor Sigaev2007-09-07
| | | | | | | | | | | | | | | | - 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.
* Improving various checks by Heikki Linnakangas <heikki@enterprisedb.com>Teodor Sigaev2007-09-07
| | | | | | | | | | | | | | | | - 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.
* Refactoring by Heikki Linnakangas <heikki@enterprisedb.com> withTeodor Sigaev2007-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Tsearch2 functionality migrates to core. The bulk of this work is byTom Lane2007-08-21
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.
