This involves modifying the module to have a stable ABI, that is, the
xslt_process() function still exists even without libxslt. It throws a
runtime error if called, but doesn't prevent executing the CREATE FUNCTION
call. This is a good thing anyway to simplify cross-version upgrades.
Get rid of the code that attempted to funnel libxml2's memory allocations
into palloc. We already knew from experience with the core xml datatype
that trying to do this is simply not reliable. Unlike the core code, I
did not bother adding a lot of PG_TRY/PG_CATCH logic to try to ensure that
everything is cleaned up on error exit. Hence, we might leak some memory
if one of these functions fails partway through. Given the deprecated
status of this contrib module and the fact that errors partway through
the functions shouldn't be too common, it doesn't seem worth worrying about.
Also fix a separate bug in xpath_table, that it did the wrong things
if given a result tuple descriptor with less than 2 columns. While
such a case isn't very useful in practice, we shouldn't fail or stomp
memory when it occurs.
Add some simple regression tests based on all the reported crash cases
that I have on hand.
This should be back-patched, but let's see if the buildfarm likes it first.
installations whose pg_config program does not appear first in the PATH.
Per gripe from Eddie Stanley and subsequent discussions with Fabien Coelho
and others.
- add some additional files to the dbmirror install (approved by
ssinger)
- add a makefile for contrib/mysql, and add mysql to the list of
contribs build by default
- use xml2-config to pickup -I flags for libxml2 in contrib/xml and
contrib/xml2

Conway.
