New submission from Francois Godin :
Using double quote around the version argument will cause a failure.
Ex (failure): "py.exe" "-3" "test.py"
=> run_child: about to run '3" "...\python.exe" "test.py"'
=> ...\python.exe: can't open file '3 test.py': [Errno 22] Invalid argument
Removing the double quote give (success): "py.exe" -3 "test.py" => run_child:
about to run '"...\python.exe" "test.py"'
This is mainly problematic when a library or a tool want to be simpler and
simply add double quotes around every parameters. This is impossible to do with
the python launcher.
The issue seems to come from the PC/launcher.c file. It is the following line
in the function process (around line 1622): command += wcslen(p);
This line is suppose to skip the -3 in the command line so that the rest can be
given to python as-is. The problem is that while command come from
GetCommandLineW and thus contain quote, p come from __wargv and does not
contain the double quote. Thus, the 2 characters "- are skipped instead of -3.
