Weak points:
- alignof
- js problems
Todo:
- make js work with C++ and mozjs-17
- then mozjs-24
- then mozjs-52
- then mozjs-60
- decrease number of warnings
By default some Python warning messages would be written to standard error
by the interpreter. To prevent these warnings from making a mess of the
ELinks screen, all warnings were turned into exceptions so they could be
caught and displayed through the usual report_scripting_error() mechanism.
With Python 3.2, this approach backfires: A new class of ResourceWarnings
that are filtered by default (and hence would *not* have been written to
standard error) are now turned into exceptions, and these exceptions can't
be caught because they're emitted from the interpreter's cleanup code. As
a result, the uncaught exceptions would make a mess of the ELinks screen.
The new solution is to replace Python's standard library function
warnings.showwarning() with one that turns warning messages into exceptions.
This means we'll wait until a warning would have been written to standard
error before turning it into an exception, so other warnings that would
never have reached that point because they're filtered will remain unseen.
(The behavior of warning messages is described in the documentation for
the "warnings" module from Python's standard library.)
cleanup_python and python_done_keybinding_interface called by it
now reset the PyObject *python_hooks, *keybindings variables back
to NULL when they release the references. Without this change,
dangling pointers left in those variables could cause problems
if the Python scripting module were deinitialized and reinitialized.
It looks like such reinitialization is not currently possible though,
because enhancement request 73 (plugins support) has not yet been
implemented.
Before this patch, init_python would crash trying to set up elinks.home
at the Python side. Now it uses None as the value in that case.
Also, init_python no longer adds "(null)" to $PYTHONPATH.
