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.

contrib/Makefile.python: build local Python from source This provides an easy way to install new or old Python versions on Unixish systems. It is mainly intended for testing Mercurial with different Python versions. Example: $ cd build $ make -f ../contrib/Makefile.python python PYTHONVER=2.4 PREFIX=/tmp/p24 $ /tmp/p24/bin/python -V Python 2.4 Tested on Fedora, Debian and Ubuntu with Python versions from 2.4 to 2.7.6. Most Python versions need some workarounds to compile on Debian-ish systems. The workarounds do not do any significant harm on Fedora.

tests: use small conditional section for tic requirement in test-status-color.t Better test coverage when curses not is available.
