Git

Google Tech TalksOctober, 12 2007ABSTRACTWhen you have hundreds of people simultaneously patching 25000 files of the Linux Kernel in sometimes conflicting ways, you might need some scheme or plan to sort all that out before you can build your next kernel and reboot. The Linux team uses "git" for their source code repository management, a homegrown solution that is optimized for highly distributed development, working with huge sets of files, merging independent work at multiple levels, and seeing who broke what. (Git has also since been notably adopted by the Cairo, x.org, and Wine teams, and is being transitioned to by the Mozilla codebase.)In my talk, I describe what "git"; is and isn't, and why you should use it instead of CVS, Subversion, SVK, Arch, Darcs, Mercurial, Monotone, Bazaar, and just about every other repository manager. I'll also walk though the basic concepts so that the manpages might start making sense. If I have time, I'll even do a live walkthrough, where you can watch how fast I make typos.Speaker: Randal Schwartz

theonebubbat: I guess that would break git. But chances are really small to accidently find two different files with the same SHA1. That's always a problem when using hashes ;-)

So what does git do if two objects wind up having the same sha1?

What's interesting is that the guy gives a tech presentation much better then allmighty Linus. That is, he doesn't swear, doesn't call the audience 'morons', etc.And that's great.

It's a fun talk if you already know and use git. Otherwise don't bother watching - you'll end up hopelessly confused. I thought the descriptions of how commit history is maintained and merges work were extremely weak to non-existent- he just kept saying you just need one number to represent all this - didn't say anything about how it really worked. Really knowledgeable speaker - unfortunately the talk is for people who already know the material and it doesn't tell them anything new.

Great talk!Some of the details are slightly wrong (signed tags are tag objects not commit objects, description of rename/copy detection is oversimplified especially for merges), and perhaps "git commit -a" should be encouraged, but it is nevertheless great talk.Nice description of fetch, rebase, publish changes workflow.

A great talk!
