New submission from Antoine Pitrou <[email protected]>:
It can be useful to enable or disable global Python features based on
command-line flags. The -X is supposed to allow implementation-specific options
but it is currently disabled for CPython. This patch allows to use -X for
arbitrary options in CPython. These options are not validated but minimally
parsed and fed into a dictionary, sys.xoptions. An example is better than a
thousand words:
$ ./python -c "import sys; print(sys.xoptions)"
{}
$ ./python -Xa,b=c,d -Xe,f=g=h -c "import sys; print(sys.xoptions)"
{'a': True, 'b': 'c', 'e': True, 'd': True, 'f': 'g=h'}
This could be useful for various debug enablers, such as Victor's SIGSEGV
handler, warnings about unclosed files, etc.
