Matthew Treinish 55e06261aa Add python_exec kwarg to processutils.execute() ... This commit adds a new kwarg to the process_utils.execute() function to specify the python executable to use when launching python to check prlimits. This is necessary when processutils.execute() is called from inside an API server running with uwsgi. In this case sys.executable is uwsgi (because uwsgi links libpython.so and is actually the interpreter) This doesn't work with the execute() function because it assumes the cpython interpreter CLI is used for the arguments it uses to call the prlimits module. To workaround this and enable API servers that may run under uwsgi to use this those applications can simply pass in an executable to use. Longer term it might be better to migrate the prlimits usage to call multiprocessing instead of subprocessing python. But that would require a more significant rewrite of both processutils and prlimit to facilitate that.
