Thanks @demanuel,
I'm getting the same compilation and test warnings with libxml2 2.12.06 from source. There's more to be tidied up.

I'm finding the tests are now noisy, but passing against Raku 2024.04, and LIbXML has started segfaulting on the Rakudo blead on a number of tests. One example is shown below. Does this match what you're seeing?

how do i run the tests?

What i'm doing is:

  1. I force installed (ignored the tests) libxml with zef
  2. cloned this repo
  3. rakudo -I. t/00dtd.t

This fails with:

LIbXML has started segfaulting on the Rakudo blead on a number of tests

THere has been a lot of refactoring in the nativecall in raku. Maybe related? https://github.com/rakudo/rakudo/commits/main

@demanuel

how do i run the tests?
The missing resources/libraries/libxml6.so file contains some additional bindings that need to be compiled first.

$ zef build . can be run to do the compilation.

Under the hood, zef executes Build.pm6 to generate and run a Makefile to do the compilation.

Yes, agree the recent NativeCall changes have broken something. I'll look at submitting a Rakudo ticket over the next couple of days. see below

I've uploaded LibXML 0.10.8 which hopefully now passes tests on the Rakudo blead. It still has those noisy compile time warnings related to xmlKeepBlanksDefaultValue and xmlLastError`, which still need to be fixed.

The problem related to usage of CArray[Str] in a couple of places. I think Raku frees the contents when garbage collecting. But these contained strings that weren't designed to be freed. These have now been eliminated.

They've always been a problem. It's just that tests are flapping at lot more on the latest Rakudo.

i was able to install. Still have the warnings above.
Thanks for the fix.

So there's three global libxml2 deprecations triggering the warnings xmlLastError, xmlKeepBlanksDefaultValue and xmlDefaultSAXLocator.

@dwarring

Looking firstly at xmlLastError . This is replaced in recent libxml2 versions with several per-context error handler as described inb the following source-code comments:

/**
 * xmlSetStructuredErrorFunc:
 * @ctx:  the new error handling context
 * @handler:  the new handler function
 *
 * DEPRECATED: Use a per-context error handler.
 *
 * It's recommended to use the per-context error handlers instead:
 *
 * - xmlCtxtSetErrorHandler (since 2.13.0)
 * - xmlTextReaderSetStructuredErrorHandler
 * - xmlXPathSetErrorHandler (since 2.13.0)
 * - xmlXIncludeSetErrorHandler (since 2.13.0)
 * - xmlSchemaSetParserStructuredErrors
 * - xmlSchemaSetValidStructuredErrors
 * - xmlRelaxNGSetParserStructuredErrors
 * - xmlRelaxNGSetValidStructuredErrors
 *
 * Set the global "structured" handler and context for error messages.
 * If handler is NULL, the error handler is deactivated.
 *
 * The structured error handler takes precedence over "generic"
 * handlers, even per-context generic handlers.
 *
 * Since this is a global setting, it's a good idea to deactivate the
 * error handler after collecting the errors you're interested in.
 *
 * For multi-threaded applications, this must be set separately for
 * each thread.
