Centralized git

Centralized git

[Javier Domingo]

I know that currently that statement (Git centralized) is an oxymoron, but
let me explain why would it be interesting.

I am currently planifying a 3D project, and I will be having large binary
files. If I add a distributed VCS, the amount of disk space required will
increase significantly.

Due to that, I started looking for an alternative VCS, such as svn, cvs.
But none of them satisfied me, mainly because they didn't have the branch
concept Git does.

I read the bzr docs, and I found that was nearly what I wanted, except for
the branch concept git has. I am maybe explaining myself in the wrong way,
but I hope someone understands.

What I would like, would be the posibility of having something like the
history horizon in bzr, or the partial repos that git-annex provides. The
idea is to have a repo with all the branches (just the head of them).

Another thing I would like to see would be being able to commit like git
actually works. Though all the history wouldn't be available, making
commits offline would be a great thing, althought later, when pushing, they
would be just in the remote, getting erased from local.

I tryed to achieve this through porcelain commands, but didn't work the few
examples I tryed.

I know this breaks with Git's main philosophy, but that is something that
would be very great. For what I know, one of the bad things to deal with is
that the compression algorithm is thought for text files.

I am looking for your answers,

Javier Domingo

You are going to transfer something that wont fit into your hard disk
up and down your network once in a while ?

I assume disk to be cheaper than network.

Network, in this case is cheaper. The thing is that If I commit
frecuently, will have plenty of GBs of history, that nearly for sure I
won't use. I just need to have other people's work to merge. But I
want to think in Git style, I am pretty accustomed to that way of
doing things. That is why I sent this mail here.

The idea is that if I modify 700MBs of video, with 20 commits I would
get in 21GB. And making a pull would be... just even more horrible
than anything. That is why I need to have also last checkouts filter.
Just download branch's HEADs.

You're obviously aware of git-annex, is there any reason you can't
just use that?

That would give you what you want, you'd have a moving window of
current files, and then you'd delete old files as they become
un-needed.

If there is a lot of static content, you should try git-media[1]. Its
specifically aimed at what you are trying to achieve.

Javier,

Are you sure you need git for those big binary files at all?

Branching makes sense only if merging makes sense, and I can hardly see
how you can merge three 700-megabyte video files.
