[Insight-developers] ITKv4: Features vs Clean up

[Rupert Brooks]

Bill,

The more i read about git, the more convinced i am, despite the
learning curve.  Its a steep one though.

Yes, i saw that line and used it.  I have studied it a bit more this
morning. The first command on that line
gives me trouble this morning - as written its

git fetch http://review.source.kitware.com/p/ITK refs/changes/51/1551/1

which to me says get from the repository named p/ITK on revew.kitware
etc a branch named refs/changes/51/1551/1

However this fails with the following
rupert at morrigan:~/src/ITK$ git fetch
http://review.source.kitware.com/p/ITK refs/changes/51/1551/1
fatal: http://review.source.kitware.com/p/ITK/info/refs download error
- The requested URL returned error: 403

I could interpret this as needed quotes around
"http://review.source.kitware.com/p/ITK refs/changes/51/1551/1" but
this gives
me a different error

fatal: Couldn't find remote ref HEAD

using ssh gives me slightly different errors.
rupert at morrigan:~/src/ITK$ git fetch
http://review.source.kitware.com/p/ITK refs/changes/51/1551/1
fatal: http://review.source.kitware.com/p/ITK/info/refs download error
- The requested URL returned error: 403
rupert at morrigan:~/src/ITK$ git fetch
ssh://review.source.kitware.com/p/ITK refs/changes/51/1551/1
Enter passphrase for key '/home/rupert/.ssh/id_rsa':
fatal: '/p/ITK': not a Gerrit project
fatal: The remote end hung up unexpectedly

After reading a lot of docs, i'm fairly convinced that this is the
right command to use (In any case, i copied it from Gerritt).
But i'm not confident enough in my git understanding to say for sure.

Just in case its relevant
rupert at morrigan:~/src/ITK$ git --version
git version 1.6.3.3
rupert at morrigan:~/src/ITK$ uname -a
Linux morrigan 2.6.31-22-generic #73-Ubuntu SMP Fri Feb 11 19:18:05
UTC 2011 x86_64 GNU/Linux

Happy Independence Day - these matters can easily wait till tomorrow.

Rupert
