Mirroring some opensource projects
Sometimes, it is real pain to stay synchronized with some projects you're using and/or modifying. Just because they do not provide revisions, or because they do, but with a tool you can't/don't want to use.
falls under the first category : it is frequently updated on EmacsWiki, but downloading the project is quite inconvenient (you need to use a script, avoid wiki download limits, you don't have easy revisions, and so on). Therefore, I have setup a bzr repository that mirrors daily changes to a file in this project. It's far from being perfect of course, since the granularity of the commits is quite arbitrary, but I find it easier anyway. You can get via
bzr branch http://archives.hodique.info/bzr/icicles
Dokuwiki and Arctic, which are respectively the wiki engine and the theme I use for this website, fall under the second category : they are managed by darcs, which is a very nice vcs, but suffers from two drawbacks (at least for me)
- it's not my tool of choice, I prefer bzr
- this site is hosted, and I'd like to easily record the patches I introduce in these softwares
The second point is the most important, of course :) In previous posts (here and there), I explained how do deal with darcs with the aid of sshfs, but it is unbearably slow. Deploying bzr on the server is much easier since it is written in Python.
When it comes to converting a repository from one vcs to another one, Tailor is the right tool to use. I won't say the migration and synchronization were without trouble, it would be a lie, but the result is very satisfying, once everything is properly setup.
For the record, here is the configuration file I use for tailoring those two projects :
[DEFAULT] verbose = True debug = True encoding = utf8 encoding-errors-policy = ignore projects = dokuwiki arctic [dokuwiki] root-directory = ~yann/Projects/tailor/dokuwiki source = darcs:dokuwiki target = bzr:dokuwiki state-file = dokuwiki.state start-revision = 2007-03-01 [bzr:dokuwiki] repository = ~yann/Projects/bzr/dokuwiki.d/dokuwiki.darcs [darcs:dokuwiki] repository = ~yann/Projects/darcs/dokuwiki [arctic] root-directory = ~yann/Projects/tailor/arctic source = darcs:arctic target = bzr:arctic state-file = arctic.state [bzr:arctic] repository = ~yann/Projects/bzr/arctic.d/arctic.darcs [darcs:arctic] repository = ~yann/Projects/darcs/arctic
After running tailor, all I have to do is to
push the repositories to their
public place. You can get them via
bzr branch http://archives.hodique.info/bzr/dokuwiki/dokuwiki.darcs bzr branch http://archives.hodique.info/bzr/arctic/arctic.darcs
Other branches will be created eventually, to reflect my personal modifications. They are intended for personal use, but feel free to have a look. After all, it's all free software :)
