git fuse | The Git List

Thomas Koch· Dec 19, 2013, 21:15 UTC · lore

Hi,

I'm thinking about using Git for web application deployment and thought that I wouldn't even need to checkout a worktree if I could access the bare git repo via fuse.

What would be the performance impact? Once the files are in the filesystem cache it shouldn't matter anymore, how fast the git fuse layer is, should it?

Do you know any active and stable git-fuse project?

a) https://github.com/davesque/gitfuse Python, last commit 1 year ago

b) https://github.com/mfontani/git-fuse-perl Perl, last commit 3 years ago

c) http://www.seas.upenn.edu/~cse400/CSE400_2008_2009/websites/grant/project.html http://repo.or.cz/w/figfs.git thesis, OCaml, last touched in 2009

d) https://github.com/rossbiro/GitFS Python, recent but declared pre-alpha

e) https://github.com/patrickhaller/git-fs C, last commit 2 years ago

f) https://github.com/wereHamster/gitfs https://blog.caurea.org/2009/07/22/having-fun-with-gitfs.html C, last commit 2 years ago

Regards,

Thomas, Given that gitweb (and more than a few other similar tools) doesn't use FUSE and works on bare repositories I question why you think you'd need (or want) to introduce the additional layer.

If your concern is caching, it should be implemented upon already rendered / prepared objects whenever possible--frequently not a file system level implementation. This is a design concern that has no specific requirement whatsoever to do with FUSE (or for that matter, with most of the VFS layer when accessing raw disk--as VFS itself is highly optimized already).

I am not qualified to answer questions about FUSE use of the VFS cache.

I would strongly consider using a tool such as Varnish if you are concerned about performance when serving static or semi-static content (may it reside in a Git repo or elsewhere). The architectural concerns of your web-app should probably guide your design in this sort of direction anyway if it will be expected to sustain notable throughput over time.

I hope that helps.

(If you want to discuss this further it would be worth considering if your questions are Git questions or web-app design questions. The latter should be taken elsewhere.)
