OK, here's a specific example. I have a repo for the dotfiles in $HOME,
for which the "active development" copy lives on my laptop. My laptop
does not run sshd, so I can push from it and pull to it, but not push to
it nor pull from it.
I also have a branch at work, which contains some work-specific patches
(for example, to change $http_proxy). Periodically I wish to push all
dotfile updates from my latop to my work machine. Normally I can just
do this with "darcs push fs:prefs", but if there is a conflict, I
instead have to do this in a temp directory:
laptop$ darcs get fs:prefs
laptop$ cd prefs
laptop$ darcs pull --all --mark-conflicts ~/prefs
laptop$ ed # resolve conflicts
laptop$ darcs record -am 'Resolve conflicts.'
laptop$ darcs push --all fs:prefs
This certainly "feels" quite tedious compared to
laptop$ darcs push fs:prefs --mark-conflicts
laptop$ ssh fs
fs$ ed # resolve conflicts
fs$ darcs record -am 'Resolve conflicts.'
Primarily because of the up-front waiting period for "darcs get", which
takes tens of seconds even with --lazy and such.
Also, because I am resolving the conflicts in a temp dir on my laptop
instead of in situ, it is harder to perform testing and easier to
introduce bugs. For example, the host fs has bash 3.0 instead of bash
3.2, so several times I have broken my login scripts with bash 3.2isms.
When I'm doing several other things, it's also very easy for me to close
the temp dir shell (which causes the temp dir to be GCd) *before* I do
the final push back to fs -- thereby losing all the conflict resolution
work that I just did.
