a2b5c90a44 hash: Fix deletion of entries during scan 
Functions like xmlCleanSpecialAttr scan a hash table and possibly delete
entries in the callback. xmlHashScanFull must detect such deletions and
rescan the entry.

This regressed when rewriting the hash table code in 4a513d56.

Fixes #626.

aca37d8c77 parser: Only enable SAX2 if there are SAX2 element handlers

fix: more pthread weak references in globals.c 2023-11-18 15:37:26 -05:00

1ac88300c1 fix: pthread weak references in globals.c 
Linking executables will fail on systems with glibc < 2.34 without
declaring these symbols as weak references.

In commit c19771c1f13de9196f98260d142d8c8672eb5733 these references
were moved to globals.c from threads.c, but the `#pragma weak`
declarations were lost in the process.

Also removing unneeded weak declarations from threads.c.

6f78efb0fa python: Make it compatible with python3.12 
Python 3.12 removes distutils so it's mandatory to use setuptools with
python >= 3.12.

This patch prints a message when trying to run the setup.py script with
a python >= 3.12 without setuptools and try to use the setuptools import
by default.

This patch also creates a new file, pyproject.toml [1], to prepare for
building in modern systems.

97e99f4112 parser: Acknowledge that entities with namespaces are broken 
Entities which reference out-of-scope namespace have always been broken.
xmlParseBalancedChunkMemoryInternal tried to reuse the namespaces
currently in scope but these namespaces were ignored by the SAX handler.
Besides, there could be different namespaces in scope when expanding the
entity again. For example:

    <!DOCTYPE doc [
      <!ENTITY ent "<ns:elem/>">
    ]>
    <doc>
      <decl1 xmlns:ns="urn:ns1">
        &ent;
      </decl1>
      <decl2 xmlns:ns="urn:ns2">
        &ent;
      </decl2>
    </doc>

Add some comments outlining possible solutions to this problem.

For now, we stop copying namespaces to the temporary parser context
in xmlParseBalancedChunkMemoryInternal. This has never really worked
and the recent changes contained a partial fix which uncovered other
problems like a use-after-free with the XML Reader interface, found
by OSS-Fuzz.
