GIT on Windows

GIT on Windows

[Panagiotis Issaris]

Hi,

As someone in the FFmpeg project asked about GIT's availability on other
operating systems, and it was mentioned that Mercurial worked fine
on Windows, I wanted to have a look whether it was already possible to run GIT
on Windows.

I first had a go at getting it working on MSys/MinGW, but as no binaries
appeared to be available and compilation wasn't trivial, I figured I'd
take the easier path using CygWin. When looking for packages to resolve the GIT
build dependencies, I noticed that a GIT package was
already available from within the CygWin installer! :-)

I tried some basic stuff, creating a repository, adding files, committing,
diffing and found out all this worked fine. I noticed that gitk also works fine.

Then I wanted to try the same on some real repository (meaning with more then
the 10 commits my testrepository contained).

I tried cloning a repository of my own but this resulted in a crash:

git clone http://lumumba.uhasselt.be/takis/git/ffmpeg-pi.git/

pissaris@pissaris ~/src/ffmpeg-pi
$ git --version
git version 1.5.1.3

I'll see if 1.5.1.4 solves this crash, and will most likely have a go at getting
the MinGW version compiled too.


Any clues on the reason for this crash? Is anyone already using GIT on Windows
on real repositories?

I don't think that the MinGW version can clone via http out of the box.
If you can, use native git protocol or ssh. They are much preferred over
http anyway (not only on Windows).

Please ignore this bugreport as GIT 1.5.1.4 indeed seems to solve 
this crash! :-) (That or the CygWin binary GIT 1.5.1.3 package 
might be broken).

Yes, I'm using Git on Cygwin on real repositories.  My largest there
is about 60 MiB, ~70,000 objects, 10,000 files.  Myself and about
25 others who are required to use Windows use it every day just fine.

I also use HTTP fetch to download the latest git.git changes so I
can build them locally (I don't use the Cygwin package, I compile it
myself from scratch) but I haven't done a clone over HTTP in ages as
I already have a local git.git clone established in a few locations.
I'd build any new clone from my existing local ones first...
