Bug Description

Characteristic: I have about 185 new files on a local working directory added to my branch. Upon commit, a number of files are added but then the system hangs. The mouse and all processes on my ubuntu 11.10 slow down. The first time was from the command line. I had to Ctrl-c to break the process.
Then i was stuck with a lock on some files in dirstate that prevented me from doing anything.

A complete reboot (restart wasn't sufficient) allowed me to bzr break-lock the process. (note that bzr info gave no indication of locked processes - not as suggested by the manual)

[SOLVED - WORKAROUND] I then used the Bazaar - Explorer gui to add parts of the branch bit by bit.
It turns out that I had some video animation files. These seemed to have caused the system hang.
It's probably a bug that you aren't warned not to add files that are too large. And that a lock is created rather than rejecting the attempted commit.

I would like to get involved with launchpad / bazaar. If someone takes this bug fix on, I'd like to ride shotgun and see how they fix it. I could do unit testing afterwards. Then i'd be on the path to being able to contribute myself. <email address hidden>

Thanks for the interest in contributing Kesten. There's actually a great way for you to get started here, as your suggestion to warn when adding large files was recently implemented on the development version of Bazaar, and you can follow nearly the whole process Shannon went through in the merge proposal here:

<https://code.launchpad.net/~weyrick/bzr/54624-warn-on-large-files/+merge/70691>

Thanks a lot martin.

I followed the link. That's great that you get so much feedback from the
team when working on a patch. I look forward to finding something to work
on. Do you have any "scrum" meeting times on the IRC?
