If I type
git branch -f master
In my repository, it tells me the same
fatal: Not a valid object name: 'master'.
same for
git branch -f master2
=> fatal: Not a valid object name: 'master'.
I guess git branch -f master2
tries to create a branch master2 after the current commit of the master branch. But it doesn't seem to exists
from git-cc.
Hi Dolanor,
The problem here is my error reporting. Basically the entire 'rebase' process ran and didn't commit anything. Git needs to have at least one commit before you can do anything interesting (like create branches).
What does your 'branches' configuration look like in the .gitcc config file?
Cheers,

When you see:
cleartool diff -diff_format -pred
That's looking for changes to a directory. Git doesn't track directories. To have files you are looking for an output like:
cleartool get -to some/file@/main/1
from git-cc.
Thanks for the quick reply here is my .git/gitcc
[master]
clearcase = /vob/daproject
from git-cc.
Actually I'm afraid I'm still stumped. I can't see the initial lshistory
command listed above Are you using 'rebase --load' with an lshistory.bak file? Or have you 'edited' the snippet you pasted?
Either way, but not specifying branches
in the .gitcc file you should be picking up the /main
branch.
Is /vob/daproject//src/Makefile
a file or a folder? From above git-cc seems to think it's a folder. If you look at .lshistory.bak can you see a line containing that file? Does it have checkinversion
or ``checkindirectory version at the start? Does any file have
checkinversion`?
Actually one thought did occur to me - there might be an error being masked here. Try changing the doCommit()
method to the following (ie remove the finally
block):
doCommit():
branch = getCurrentBranch()
if branch:
git_exec(['checkout', CC_TAG])
commit(cs)
I'm sorry I can't be much help.
from git-cc.
I loaded the history (too many commits otherwise. the history is ~746000 lines long) with rebase --load
The first ct command at the "beginning" (at the end of the lshistory file) are mkelemdirectory. The "first" (last in file) checkin which is a checkindirectory is at line ~738000.
I've launched the version with your doCommit() version. I'll update with the result
from git-cc.
With your doCommit, I got this. My view is static :

Hi Dolanor,
Are you still running git-cc in your Clearcase directory? git-cc needs to be run in a directory where it can modify files so it can recreate the history.
Charles
from git-cc.
No, my static view is in /vob/daproject
and the git import dir where I call the git-cc is in /home/myUser/git-cc-import
from git-cc.
Hmm, that doesn't really correspond with the error I'm seeing:
toFile = path(join(GIT_DIR, file))
GIT_DIR
should be the root of the current git directory, and file
is the relative path to JUNK/2011_and_before/subdirs.old
. Maybe put some print statements around that line and see what both those variables are.
from git-cc.
I created a new import, still using my lshistory.bak and changing the directory of the import.
Yes I edited the log just to avoid some privacy issue, but the FS address remains coherent I think.
I added the output in the end

Hi Dolandor,
Apologies. I thought you were running git-cc from the wrong place. Turns out join
in Python doesn't quite do what I expect it to do. join('/a', '/b')
will return /b
not /a/b
. So the problem is that file
is absolute, not relative. I'm wondering why that's different for you and how they ended up like that.
In any case you need to strip off the leading '/vob/daproject//' from each file. You can either do that manually by editing lshistory.bak or modifying the python rebase.py
file.
Good luck,
Charles

It worked !
But the project is too big to be imported, Clearcase stopped seeing revision in the git-cc way of doing things. So I could only import 33 commits on 500k and so the history stays 17 years before…
For that, I modified my lshistory.bak instead of modifying rebase.py
Anyway, I still adapted the gitcc script to work on RedHat 5 without a 2.6 python.

Hey, so does mean you imported all your history after fixing lshistory.bak? Are you switching to Git now, or do you still have to use Clearcase officially?
My apologies that things were so painful, but I hope you can stay on Git now. :)
from git-cc.
I've switched project. Full git for now. They want us to work on TFS or SVN.
We don't give a damn because we will continue on git until we need to release something… Then we will make a major push, and that's it.
from git-cc.
Right on! FYI there are (better) Git bridge tools for both SVN and TFS, and Microsoft actually released the new version of TFS with Git support.
In any case I can't believe people are still using anything but Git these days. Best of luck.
