From 49e3e6196c243ba1995ec1000b51ccee768493a4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20G=C3=B3rny?= Date: Sun, 11 Jul 2010 11:50:02 +0200 Subject: Rewrite VCS detection code in repoman. Move the real code into repoman.utilities. Support any repository depth for distributed SCMs -- i.e. Sunrise through git-svn. Bail out if more than one control version directory is found at the same depth. --- pym/repoman/utilities.py | 44 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) (limited to 'pym/repoman') diff --git a/pym/repoman/utilities.py b/pym/repoman/utilities.py index 305080411..a07b4a436 100644 --- a/pym/repoman/utilities.py +++ b/pym/repoman/utilities.py @@ -433,3 +433,47 @@ def FindPortdir(settings): portdir += '/' return [normalize_path(x) for x in (portdir, portdir_overlay, location)] + +def FindVCS(): + """ Try to figure out in what VCS' working tree we are.
