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.
For https://bugzilla.gnome.org/show_bug.cgi?id=734017
Solaris has had libxml2 version 2.9.1 for a while, with Python versions 2.6 and
2.7. While preparing to also build a module for Python 3.4, we ran into an
issue with the test case sync.py failing. The failure involved parsing a
string that included a Python dictionary, then complaining when the order of
the parsed result did not match the original order. But Python dictionaries
are unordered by definition; see section 5.5 of
https://docs.python.org/2/tutorial/datastructures.html . For whatever reason,
Python 2.6 and 2.7 always happened to report the pair of values back in their
original order, but with Python 3.4 the order is random. The attached patch
allows for either order; it also fixes a typo that was repeated several times
thanks to the magic of copy & paste.
* parser.c: make the push interfaces synchronous
* python/tests/sync.py: added a specific test
* python/tests/Makefile.am doc/examples/Makefile.am
doc/examples/index.py: added the new test, cleaning up
"make tests" output
