HELP: GIT Cloning failed

[Ju, Seokmann]

Hi,

Recently, I found that cloning from GIT server has been failed.
I'm using following script for it.
---
...
rm -r /home/git/kernels/2.4/linux-2.4.git
cg-clone
http://www.kernel.org/pub/scm/linux/kernel/git/marcelo/linux-2.4.git/
/home/git/kernels/2.4/linux-2.4.git/
sync
rm -r /home/git/kernels/2.4/linux-2.6.git
cg-clone
http://www.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git/
/home/git/kernels/2.4/linux-2.6.git/
sync
rm -r /home/git/kernels/2.4/scsi-misc-2.6.git
cg-clone
http://www.kernel.org/pub/scm/linux/kernel/git/marcelo/scsi-misc-2.6.git
/home/git/kernels/2.4/scsi-misc-2.6.git
sync
...
---

In the script, I'm cloning 3 different sources. First two sources
getting successfully cloned, however, last one is getting failed with
following error messages,
---
Fetching head...

Above script worked without any problem when I started several months
ago and I'm not sure when did it stop working.
I'm using _cron_ utility on my Linux box for scheduled execution of the
script.

Any comment would be appreciated.

Thank you,

Seokmann

It looks like the jejb scsi-misc archive might not have been
configured properly for http transfers.  There's a script below
which just uses git commands (not cogito) and the native git
protocol which tests out okay here.

A few comments though:

 - Apparently the scsi misc tree you want is actually under "jejb"
   rather than "marcelo" which you had in your script.

 - It's better to use the native git protocol when possible
   (well, the benefits are less on initial clone, but it's still
   a good practice)

 - You're causing a lot of unnecessary traffic for kernel.org by
   cloning a fresh copy of all these trees, it would be much better
   to clone just _once_ and then simply "git pull" in any updates.

 - Two of the trees you're cloning are very close in content to
   each other (linux-2.6 & scsi-misc-2.6) so you can use the git
   "--reference" option to share local objects saving disk space
   (and reducing bandwidth needs even further)

Cheers,
Sean

I will try with the script and rest of your comments as well.
Thank you for your guidence.

Re: HELP: GIT Cloning failed

[Phillip Susi]

Is there a reason that you regularly delete and re-download the entire 
repository, rather than simply doing a git pull to update your existing 
clone?
