[9fans] any git client?

[Mayuresh Kathe]

Is there any Git client available under Plan 9?
If not, is there a port of "libgit2" available?

Re: [9fans] any git client?

[Chris McGee]

There is the beginnings of a client written in Go here that should work in Plan 9.

I have heard rumours of a port libgit2 somewhere.

i started to look at this, someone gave me their current work which opens .git files, but in reality i use my windows machine (which i use for browsing) to run git.

at the risk of being boring, i have a cpu(1) like tool which runs in windows so i can jump to running plan9 commands (e.g. rc(1)) on windows from my plan9 desktop.

this also gets used for cross compilation, svn, and some other inhouse tools.

There's Ori's git9 wip: https://bitbucket.org/oridb/git9

WIP is the key word. It's not usable (yet).

git/clone:  basically works, but is missing a bit of code to update
            branches.
git/fs:     will serve up commits as an fs, but it's rather crashy.
git/commit: makes commits, really clunky.
git/push:   started on an implementation, doesn't yet work.

Merging, branching, etc should be relatviely easy to do on top of
git/fs, but I haven't had time to take a look at them.

Besides those, David has an rc version: http://9legacy.org/9legacy/tools/git

Another alternative, if you have a Plan 9 fileserver, is to import the
right hierarchy on Linux using P9P tools and then use git on Linux.

to add to the last comment from skip, also note the availability of a
working ssh and sshfs on 9front :)

Ssh also works fine on traditional plan9 if you apply these patches
from http://9legacy.org/patch.html :
	tls-devtls12.diff
	tls-tlshand12.diff
	libsec-x509-sha2.diff
	libsec-tlshand12-nossl3.diff
	libsec-tlshand12-norc4.diff
	libsec-tlshand12-fixes.diff
	libsec-x509-sig.diff

These are already applied in the raspberry pi image:
    http://9p.io/sources/contrib.miller/9pi.img.gz

Libgit2 *is not* portable. They use mmap everywhere for I/O, which breaks
for 9P or NFS.

How does one apply these patches?
By mounting http://9legacy.org/9legacy/patch on /n/sources/patch and
then using patch/apply? Or is there some other way?
Thanks.

I download them with hget and apply them with ape/patch.  There might
be other ways too.

Thanks.

I'm pretty sure I once figured out how to emulate mmap, at least in a general way.  Maybe it was relying on the process to call the flush routine.  Flushing could also happen on a timer or atexit or whatever.

libgit2 has defines that allow it to work without mmap. It needs a bit of
work to port to plan 9, but I did it in the past.

https://bitbucket.org/oridb/libgit2/commits/all

I'm not currently maintaining it. I'm not sure how much of it actually works.
