- Removed patches (already in upstream):
* libxml2-CVE-2023-39615.patch
* libxml2-CVE-2023-45322.patch
* libxml2-make-XPATH_MAX_NODESET_LENGTH-configurable.patch
* python312.patch
- Update to 2.12.0:
* Major changes:
- Most of the known issues leading to quadratic behavior in the
XML parser were fixed. Internal hash tables were rewritten to
reduce memory consumption.
- Starting with this release, it should be enough to add the
--with-legacy configuration option to provide maximum ABI
compatibility.
- libxml2 will now store global variables in thread-local
storage if supported by the compiler. This avoids allocating
the data lazily which can result in a fatal error condition.
- A new API function xmlCheckThreadLocalStorage was added so the
allocation can be checked earlier if compiler TLS is not
supported.
- To prepare for future improvements, some API functions now
expect or return a const xmlError struct.
- Several cyclic dependencies in public header files were fixed.
- Refactoring of the encoding code has been mostly completed.
Calling xmlSwitchEncoding from client code is now fully
supported, for example to override the encoding for the push
parser.
- When parsing data from memory, libxml2 will now stream data
chunk by chunk instead of copying the whole buffer (possibly
twice with encodings), reducing peak memory consumption
considerably.
