--------------------------------------
Summary: Git fast remote polling always triggered, missing locale
Key: JENKINS-13356
URL: https://issues.jenkins-ci.org/browse/JENKINS-13356
Project: Jenkins
Issue Type: Bug
Components: git
Reporter: Marc Günther
Assignee: Nicolas De Loof
Priority: Minor
Symptom:
All jobs which had fast remote polling enabled triggered on every change in
their repository, even if it was on an unrelated branch.
Cause:
Fast remote polling issues a {{git ls-remote -h <repo> <branch>}} command. The
output of this command is supposed to be the sha hash of the last commit, but
in our case it was:
{{bash: warning: setlocale: LC_ALL: cannot}}
Explanation:
We have some slaves that use a german locale. This locale does not exist on the
Git repository server nor on the Jenkins server. Installing it on the Jenkins
server had no effect, as the above warning comes from the Git repository server.
Quick fix:
Install the missing locale on the both servers.
Solution:
Installing locales on some server should not be required. Either ignore stderr
when issuing the {{git ls-remote}} command, or manipulate the passed in
environment to something that does not cause side effects like this.
Question:
Why is the environment from the slave used on the server when doing the
polling? {{LC_ALL}} is not set on our Jenkins server, so this definitely comes
from a slave.
