Tom Lane	8a0137d785	Fix contrib/xml2 so regression test still works when it's built without libxslt. ... 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.	16 years ago
Tom Lane	a8ab473383	Remove xmlCleanupParser calls from contrib/xml2. ... These are unnecessary and probably dangerous. I don't see any immediate risk situations in the core XML support or contrib/xml2 itself, but there could be issues with external uses of libxml2, and in any case it's an accident waiting to happen.	16 years ago
Tom Lane	94152f93f5	Back-patch today's memory management fixups in contrib/xml2. ... Prior to 8.3, these changes are not critical for compatibility with core Postgres, since core had no libxml2 calls then. However there is still a risk if contrib/xml2 is used along with libxml2 functionality in Perl or other loadable modules. So back-patch to all versions. Also back-patch addition of regression tests. I'm not sure how many of the cases are interesting without the interaction with core xml code, but a silly regression test is still better than none at all.	16 years ago
Tom Lane	b99751a199	Fix xslt_process() to ensure that it inserts a NULL terminator after the ... last pair of parameter name/value strings, even when there are MAXPARAMS of them. Aboriginal bug in contrib/xml2, noted while studying bug #4912 (though I'm not sure whether there's something else involved in that report). This might be thought a security issue, since it's a potential backend crash; but considering that untrustworthy users shouldn't be allowed to get their hands on xslt_process() anyway, it's probably not worth getting excited about.	17 years ago

Bruce Momjian	adca025c9e	Thanks to the generous support of Torchbox (http://www.torchbox.com), I ... have been able to significantly improve the contrib/xml XPath integration code. New features: * XPath set-returning function allows multiple results from an several XPath queries to be used as a virtual table. * Using libxslt, XSLT transformations (with and without parameters) are supported. (Caution: This support allows generic URL fetching from within the backend as well). I've removed the old code so that it is all libxml based. Rather than attach as a patch, I've put the tar.gz (10k!) at http://www.azuli.co.uk/pgxml-1.0.tar.gz (all files in archive are xml/....). I think this is worth replacing the contrib version with, even though the function names have changed (though the same functionality is there), because it includes a SRF and some SPI usage, in addition to linking to an external library. And it isn't a big module! Obviously, I understand that people might prefer to move it elsewhere, or might have reservations about replacing an existing contrib module with an incompatible one. I'm open to suggestions. John Gray	22 years ago
