Problem with migrating into github about cmssw

[davidlt]

@kkaadze, have you initialized CMSSW environment? (cmsenv or eval $(scram r -sh) for bash).

The problem is that default push strategy is not understood by git version you have now. This should be the case if you are currently using older git version, but should not be the case if you are in CMSSW environment. You can manually modify GIT configuration ~/.gitconfig and change push.default. I would suggest to pick matching for now.

Probably this happened: in CMSSW environment GIT printed a message about push.default change in upcoming GIT 2.0 and required you to select the default value. GIT does that in order to make sure that migration to GIT 2.0 would not yield a different behavior. Now if you use SLC5 or SLC6 system GIT, which is older comparing to CMSSW version, it does not understand simple strategy.

Hello,

Thanks for feedback. I changed ~/.gitconfig into this:
[push]
default = matching

but still when executing instructions on this page:
http://cms-sw.github.io/cmssw/usercode-faq.html
after command

git push --mirror -u origin

I get:

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

What is going on?

Thanks,
keti

@kkaadze , it's actually documented in the link you provided.

In case you get the following message:

Permission denied (publickey).
fatal: The remote end hung up unexpectedly
you forgot to register your ssh key when you registered to github, you can do it by going to https://github.com/settings/ssh and adding your public key there.

Hello,

Thanks for feedback! I did following command and got error.

[kkaadze@lxplus0274 usercode]$ git push --mirror -u origin
ERROR: Repository not found.
fatal: The remote end hung up unexpectedly

Then I tired to do git push origin master before the last line, but still
the error:
ERROR: Repository not found.
fatal: The remote end hung up unexpectedly

Could you suggest what is wrong?
thanks,
keti

@kkaadze , have you configured your remote?

git remote -v

It should show origin remote as [email protected]:kkaadze/usercode.git

[kkaadze]

It seems that when I try to do this command:

setenv MY_GITHUB_USER git config --get user.github

my user name is not set up, i.e.

echo $MY_GITHUB_USER
I get empty string.

Thanks,
Keti

@kkaadze , makes sense. Do:

git config --global user.github kkaadze

Hello,

I am trying to do "git pull" to get some changes from software package
in CMSSW_5_3_11 on slc6 and get following error

git: /afs/
cern.ch/cms/slc5_amd64_gcc462/cms/cmssw/CMSSW_5_3_11/external/slc5_amd64_gcc462/lib/libz.so.1:
version `ZLIB_1.2.0' not found (required by git)

Could you please suggest what am I doing wrong? it was working last week, I
think.

Is there some CMSSW-GIT related FAQs or twiki where one can search for some
solutions on basic command errors?

Many thanks,
Keti

Developing using a slc5 release on slc6 is not supported (regardless of git, BTW).

Hi Giulio,

Thanks for the feedback. I have to use CMSSW_5X series for my code. So I
logged in to slc5 machine and tried to
do "git pull" and get following message:
"fatal: Authentication failed"

Could you suggest what is wrong now?

Thanks a lot,
Keti

Please make sure you have the correct access rights

Can you provide me the exact steps you used?

[kkaadze]

Could you clarify which steps do you mean? I created this release a few
weeks ago and I was working in it
fine. Then, sometime last week, when I tried to do "git pull" or "git push"
it was no longer working.
After that I followed the feedback whatever I received from you
step-by-step as you told me.

Many thanks,
Keti
