Description of problem: meld <file> is supposed to start a version control comparison, and it indeed does so in a (say) Subversion work directory. However, this is broken for Mercurial when <file> is not at the same level as the special .hg directory. Version-Release number of selected component (if applicable): I've tried meld 1.3 to 1.5.1 (rawhide). How reproducible: Always. Steps to Reproduce: 1. Create a Mercurial repository (hg init w) 2. Add a file and modify it (mkdir w/d; cd w/d; echo empty > f; hg add f; hg ci -m test; echo more >> f) 3. Launch meld with <file> (meld f) Actual results: meld GUI with one panel, no diff. Expected results: meld GUI with two panels, with diff.
Note that meld <dir> knows where .hg is (even if it is not at the current work directory), and properly show the version control comparison for directories. The bug only happens to meld <file>.
This has been fixed in the upstream (https://bugzilla.gnome.org/show_bug.cgi?id=650074). A one-line change. Guess the next release could incorporate the fix.
Thanks for your assistance! :-)
