* Adjust with-system-tzdata patch to not attempt to install a symlink,Tom Lane2007-08-25
| | | | | | but just hardwire the specified timezone database path into the executable. Per discussion, this avoids some packaging disadvantages of using a symlink.

| | | | | | | | | | | | | | | relcache entry after having heap_close'd it. This could lead to misbehavior if a relcache flush wiped out the cache entry meanwhile. In 8.2 there is a very real risk of CREATE INDEX CONCURRENTLY using the wrong relid for locking and waiting purposes. I think the bug is only cosmetic in 8.0 and 8.1, because their transgression is limited to using RelationGetRelationName(rel) in an ereport message immediately after heap_close, and there's no way (except with special debugging options) for a cache flush to occur in that interval. Not quite sure that it's cosmetic in 7.4, but seems best to patch anyway. Found by trying to run the regression tests with CLOBBER_CACHE_ALWAYS enabled. Maybe we should try to do that on a regular basis --- it's awfully slow, but perhaps some fast buildfarm machine could do it once in awhile.

* Cleanup for some problems in tsearch patch:Tom Lane2007-08-25
| | | | | | | | | | | | | | - ispell initialization crashed on empty dictionary file - ispell initialization crashed on affix file with prefixes but no suffixes - stop words file was run through pg_verify_mbstr, with database encoding, but it's supposed to be UTF-8; similar bug for synonym files - bunch of comments added, typos fixed, and other cleanup Introduced consistent encoding checking/conversion of data read from tsearch configuration files, by doing this in a single t_readline() subroutine (replacing direct usages of fgets). Cleaned up API for readstopwords too. Heikki Linnakangas
* Fix combo_decrypt() to throw an error for zero-length input when using aTom Lane2007-08-23
| | | | | | | | padded encryption scheme. Formerly it would try to access res[(unsigned) -1], which resulted in core dumps on 64-bit machines, and was certainly trouble waiting to happen on 32-bit machines (though in at least the known case it was harmless because that byte would be overwritten after return). Per report from Ken Colson; fix by Marko Kreen.

* Remove option to change parser of an existing text search configuration.Tom Lane2007-08-22
| | | | | | This prevents needing to do complex and poorly-defined updates of the mapping table if the new parser has different token types than the old. Per discussion.

* Simplify the syntax of CREATE/ALTER TEXT SEARCH DICTIONARY by treating theTom Lane2007-08-22
| | | | | | | | | | | | init options of the template as top-level options in the syntax. This also makes ALTER a bit easier to use, since options can be replaced individually. I also made these statements verify that the tmplinit method will accept the new settings before they get stored; in the original coding you didn't find out about mistakes until the dictionary got invoked. Under the hood, init methods now get options as a List of DefElem instead of a raw text string --- that lets tsearch use existing options-pushing code instead of duplicating functionality.
* Simplify CREATE TEXT SEARCH CONFIGURATION by eliminating the separateTom Lane2007-08-21
| | | | | | | | | 'with map' parameter; as things now stand there's really not much point in specifying a config-to-copy if you don't copy its map. Also, use COPY instead of TEMPLATE as the key word for a config-to-copy, so as to avoid confusion with text search templates. Per discussion; the just-committed reference page for the command already describes it this way.
* First rough cut at text search documentation: bare bones referenceTom Lane2007-08-21

* Exclude snowball/libstemmer/ files from the set processed by pgindent.Tom Lane2007-08-21
| | | | | | There's not much point in prettifying machine-generated code, and it seems best to keep these files exactly like upstream anyway. Also add some notes about why various files are excluded.

* Arrange to cache a ResultRelInfo in the executor's EState for relations thatTom Lane2007-08-15
| | | | | | | | | | | | | are not one of the query's defined result relations, but nonetheless have triggers fired against them while the query is active. This was formerly impossible but can now occur because of my recent patch to fix the firing order for RI triggers. Caching a ResultRelInfo avoids duplicating work by repeatedly opening and closing the same relation, and also allows EXPLAIN ANALYZE to "see" and report on these extra triggers. Use the same mechanism to cache open relations when firing deferred triggers at transaction shutdown; this replaces the former one-element-cache strategy used in that case, and should improve performance a bit when there are deferred triggers on a number of relations.
* Repair problems occurring when multiple RI updates have to be done to the sameTom Lane2007-08-15
| | | | | | | | | row within one query: we were firing check triggers before all the updates were done, leading to bogus failures. Fix by making the triggers queued by an RI update go at the end of the outer query's trigger event list, thereby effectively making the processing "breadth-first". This was indeed how it worked pre-8.0, so the bug does not occur in the 7.x branches. Per report from Pavel Stehule.
