From e7fefbf68dc3384b835d38bd8897657d7289f826 Mon Sep 17 00:00:00 2001 From: Mark Hammond Date: Wed, 3 Apr 2002 01:47:00 +0000 Subject: Fix bugs: 457466: popenx() argument mangling hangs python 226766: popen('python -c"...."') tends to hang Fixes argument quoting in w9xpopen.exe for Windows 9x. w9xpopen.exe also never attempts to display a MessageBox when not executed interactively. Added test_popen() test. This test currently just executes "python -c ..." as a child process, and checks that the expected arguments were all recieved correctly by the child process. This test succeeds for me on Win9x, win2k and Linux, and I hope it does for other popen supported platforms too :) --- Lib/test/test_popen.py | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 Lib/test/test_popen.py (limited to 'Lib/test/test_popen.py') diff --git a/Lib/test/test_popen.py b/Lib/test/test_popen.py new file mode 100644 index 0000000000..2681eb0fe8 --- /dev/null +++ b/Lib/test/test_popen.py @@ -0,0 +1,36 @@ +#! /usr/bin/env python +"""Basic tests for os.popen() + + Particularly useful for platforms that fake popen. +""" + +import os +import sys +from test_support import TestSkipped +from os import popen + +# Test that command-lines get down as we expect. +# To do this we execute: +# python -c "import sys;print sys.argv" {rest_of_commandline} +# This results in Python being spawned and printing the sys.argv list. +# We can then eval() the result of this, and see what each argv was. +def _do_test_commandline(cmdline, expected): + cmd = 'python -c "import sys;print sys.argv" %s' % (cmdline,) + data = popen(cmd).read() + got = eval(data)[1:] # strip off argv[0] + if got != expected: + print "Error in popen commandline handling." + print " executed '%s', expected '%r', but got '%r'" \ + % (cmdline, expected, got) + +def _test_commandline(): + _do_test_commandline("foo bar", ["foo", "bar"]) + _do_test_commandline('foo "spam and eggs" "silly walk"', ["foo", "spam and eggs", "silly walk"]) + _do_test_commandline('foo "a \\"quoted\\" arg" bar', ["foo", 'a "quoted" arg', "bar"]) + print "popen seemed to process the command-line correctly" + +def main(): + print "Test popen:" + _test_commandline() + +main() -- cgit v1.2.1
