Ungit fails on repositories with many files

[grundprinzip]

Unfortunately ungit fails on larger repositories (at least on my Mac). The reported error is:

(CarbonCore.framework) FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-21)

And after some googling this leads to this issue in Node.js - nodejs/node-v0.x-archive#5463

As a consequence using ungit on some of my repositories is just impossible :(

+1 one for that
i was able to se some graph then it dies :(

My repo is relatively small, but has lots of fork and merges, and it is unusable for me as well.

Looks like a fix is in the works joyent/libuv#894

Despite that we're definitely going to fix it, please consider watching less directories if possible. This error happens when trying to watch a lot of directories using fs.watch, and workaround that I've developed is O(n^2) .

Hm I could make a "manual refresh" mode I guess (where you'd have to press a button to get the changes into the staging area). Not super beautiful but maybe it could be a good enough compromise to make it usable for those repositories too?

This might be a dumb idea, but instead of watching files could you simply poll git status every 1-2 seconds? Maybe use polling as a fallback once the file count goes over a certain threshold.

[indutny]

Wait a minute, watching files is ok. Just avoid watching a lot of directories at once, usually its not even necessary, because fs.watch() on osx will emit events from subdirectories too!

[FredrikNoren]

I've made a fix (ref above) that I hope will fix this, together with @indutny 's fs.watcher fix. Anyone who's experience problem with this please try ungit master (or wait for the next release) and node >= 0.10.17 to see if it works now.

Closing this now, please re-open if the problem remains after 0.2.0
