Git fetch hangs

Question

I have my working copy of git repository (not bare repo). I also setup local jenkins and my jobs were pointing to this repo. Everything worked fine. I think I've updated jenkins yesterday and this morning I discovered that my jobs started failing. Because they can not fetch source from my repo (it gets timeout).

So I started investigation. I decided to repeat git command lines in terminal to check if I can report the issue. Here is what I'm doing:

git config remote.origin.url file:///Users/eugenmartynov/Development/source/company/app-android
git fetch origin

And it hangs. And I don't have a clue what to check else.

I have git version 2.8.3. But it doesn't matter because I see same behaviour with using default version from Xcode tools

This is what I see if I try turn git trace logging:

git fetch origin
14:25:53.549772 git.c:350               trace: built-in: git 'fetch' 'origin'
14:25:53.553987 run-command.c:336       trace: run_command: 'git-upload-pack '\''/Users/eugenmartynov/Development/source/company/app-android/.git'\'''

14:25:53.570196 run-command.c:336       trace: run_command: 'rev-list' '--objects' '--stdin' '--not' '--all' '--quiet'

Here is log for past success job:

If you try `git remote set-url origin file:///Users/....` and then try to fetch, is the result the same? — 1615903, May 31 '16 at 11:24
It sounds like you change the url of origin often... Any reason you're just not adding another remote? — g19fanatic, May 31 '16 at 11:42
I have issue with local jenkins. With commands I'm trying to report what jenkins git plugin is doing — Eugen Martynov, May 31 '16 at 12:02
No just hangs, I will try see if I can log something with git — Eugen Martynov, May 31 '16 at 12:25

I guess you are using wrong url. For a local path you just use the path. Your url looks like an UNC path, i.e. Users is a host name and the rest is shared directory. So, it tries to resolve a host name which could take some time.

Your url is missing disk name. I guess it is Windows.

So, you could just provide full path, I guess git remote set-url origin c:/Users/eugenmartynov/Development/source/company/app-android. Or if I am right, you could put more slashes: file://///c:/....

BTW, git fetch could accept URLs, not necessary to add remotes.

Two comments, 1) I'm on Mac machine, 2) it was working before, what changed? – Eugen Martynov May 31 '16 at 12:43
@EugenMartynov Hm, weird... Try to use just path then: `git fetch /Users/eugenmartynov/Development/source/company/app-android/.git ...`. Does Jenkins run as the same user? Does it actually have access to a home directory? – kan May 31 '16 at 13:19
It runs as the same user. `git fetch` also hangs – Eugen Martynov May 31 '16 at 13:22
@EugenMartynov It could be broken installation. E.g. http://stackoverflow.com/questions/12613315/git-hangs-indefinitely-broke-with-osx-credential-helper-i-think Try to download fresh git distributive and use it directly. – kan May 31 '16 at 13:35
It is also not a case. I'm closing the questions, since I pointed my local jenkins to remote git, don't have time more to spend on it – Eugen Martynov May 31 '16 at 14:07
