Bazaar

What's the difference between push & commit, or pull & update?

Asked by Zearin

I want to set up my laptop (primary machine with all my code) and desktop to sync my code using Bazaar. However, some of Bazaar's flexibility is actually causing me a bit of confusion. :)

Under what circumstances would I want to use push instead of commit? And similarly, under what circumstances would I want to use pull instead of update?

Commit saves changes locally, but doesn't send them anywhere. You would use "push" when you are ready to send your changes to an external repository. Update and pull are a little bit different. That has to do with how you initially downloaded your repository.

I've also put some bzr screen casts up on ShowMeDo that have the *very* basics of installing bzr:

Thanks EmmaJane, that helped…

The wording from the pull vs. update FAQ gives the impression that 'update' is only really used when there is a Central repository setup. Is this true?

(Your screencast was also very well done, by the way! Keep up the great work! =)

That's right, Zearin. The pairs are like this:
branch + pull (commits are local until you "push" the updates back)
checkout + update (commits are automatically sent to the central repository)

There's more information about checkouts at:
