Hi darcs gurus, hi Duncan,
I'm stuck! I've just tried to separate the Gtk2Hs repo on
code.haskell.org into it's constituent libraries. What we want is to
extract some of the libraries that Gtk2Hs provides into their own
repositories without loosing their history. The problem is that darcs
will only checkout a directory that does not yet exist. So I've tried:
sim...@nun:/srv/code/webkit$ darcs get --lazy /srv/code/gtk2hs
Finished getting.
sim...@nun:/srv/code/webkit$ mv gtk2hs/_darcs .
sim...@nun:/srv/code/webkit$ mv gtk2hs/webkit .
sim...@nun:/srv/code/webkit$ darcs mv webkit/* .
sim...@nun:/srv/code/webkit$ rmdir webkit/
sim...@nun:/srv/code/webkit$ rm -rf gtk2hs/
sim...@nun:/srv/code/webkit$ darcs record
This seems to work great: webkit only contains the files it should and
recording the patch gives me exactly the movements of the webkit files
one level up and the removal of all other files. However, when I check
out on my local computer I get:
~/source as49$ darcs get sim...@code.haskell.org:/srv/code/webkit
Copying patches, to get lazy repository hit ctrl-C...
darcs failed: Couldn't fetch `0000001146-
ffed5fe22fabf1987787fe71d2c6c2e3a06d53e176e52bad3112d8bba73f9440'
in subdir patches from sources:
thisrepo:/Users/as49/source/webkit
repo:sim...@code.haskell.org:/srv/code/webkit
repo:/srv/code/gtk2hs
thisrepo:/srv/code/webkit/gtk2hs
I *think* what this means is that darcs on code.haskell.org tries to
pull more patches from the original repo but fails to do so (even
though I used absolute path names).
The problem is that when you did a "get" on code.haskell.org, the other
repo was /srv/code/gtk2hs, and now that you're on a different machine
that path is no longer accessible.
Either use non-lazy repositories, or pull down the whole gtk2hs
repository locally so that all the patches end up in your local cache
(~/.darcs/cache). Non-lazy repos aren't as bad as they seem, because
darcs hard-links all the patch files together.
Cheers,
Simon
