This allows to report the reason why opening a file failed to the parser
context and improve error messages. Now we can also remove the stat call
before opening a file.
Introduce xmlStrVASPrintf, trying to handle buggy snprintf
implementations.
Introduce xmlSetError to set errors atomically.
Introduce xmlUpdateError to set an error, fixing up node, file and line.
Introduce helper function xmlRaiseMemoryError.
Make legacy error handlers call xmlReportError, avoiding checks in
xmlVRaiseError.
Remove fragile support for getting file and line info from XInclude
nodes.
Add the directory containing libxml2.dll with os.add_dll_directory to
make tests work on MinGW.
This has changed in Python 3.8 but for some reason, the issue only
turned up with Python 3.11 on MinGW. Contrary to documentation, copying
libxml2.dll into the directory containing the .pyd file doesn't work.
As per https://peps.python.org/pep-0394/, the python binary can be one
of the following options:
- Python 2
- Python 3
- Not exist
All of the scripts in libxml2 use 'python', which may not exist.
As Python 2 reached EOL on the 1st January 2020, it's safe to move the
scripts to use python3 explicitly.
It is possible to make xmlIO handle any protocol by means of
xmlRegisterInputCallback(). However, that function is currently only
available in C API. So, the natural solution seems to be implementing Python
bindings for the xmlRegisterInputCallback.
* python/generator.py: skip xmlPopInputCallbacks
* python/libxml.c python/libxml.py python/libxml_wrap.h: implement the
wrappers
* python/tests/input_callback.py python/tests/Makefile.am: also add a test case
