tests: on windows, run command explicitly in sh for working command substitution On windows, os.system runs the command in cmd.exe, which does not know command substitution. To let this work, run the command explicitly in sh. This fixes the failure of this test on windows.

tests: test-module-imports.t works on windows (with backslash path sep) Transform the backslashes to slashes on windows, because they are eaten up by the shell. (Similar as done in test-check-pyflakes.t.) This test will not produce a traceback on windows anymore. But the test still fails because the detected mixed imports differ.

qimport: allow importing URLs

revset: fixed bug where revset returning order was being changed Some revsets were innecesarily turning the subset into a set before iterating over it. This led to returning order changing in some cases.

itersubrepos: move to scmutil to break a direct import cycle

import-checker: handle standard modules with arch in the filename Installations with module names like /usr/lib/python2.7/lib-dynload/bz2.x86_64-linux-gnu.so occurs in the wild. Let's just ignore everything after first '.' when guessing the Python module name.

tests: use ls instead of find, all files are in the same directory In this case find has no advantage compared to ls. Descending into directories is unnecessary, because there are none.

commands: hg debuginstall checks missing templates (issue4151) Missing templates where not reported as a problem, only an empty bracket were shown as indication of no found template directory: $ hg debuginstall *...some lines* checking templates ()... *...some lines* no problems detected Now the problem is reported and extended with some information. The style of the messages is adapted to the other messages of debuginstall. When no templates directories exist, it writes: $ hg debuginstall *...some lines* checking templates ()... no template directories found (templates seem to have been installed incorrectly) *...some lines* 1 problems detected, please check your install! When the template map is not found, it writes: $ hg debuginstall *...some lines* checking templates (/path/to/mercurial/templates)... template 'default' not found (templates seem to have been installed incorrectly) *...some lines* 1 problems detected, please check your install! When the template map is buggy the message is the same as before. The error message is shown before the line "(templates seem ...)". No test is added because testing this failure is complicated. It would require to modify the templates directory of the mercurial installation, or to monkey patch a function (os.listdir or any from mercurial.templater) by a test extension.
