Re: jenkins build hangs while trying to check for modifications on git
Thanks Scott, no we are not on windows, it's a SmartOs box (an OS I never used before): I have some fear that there might be a bug in the git version over there, but as I replied to Jonathan we need to find out first if it's a network issue.. cheers On Fri, Apr 5, 2013 at 8:54 PM, Scott Evans wrote: > Antonio, > > Is this on a Windows box with more than one agent configured to run on it > and possibly more than one agent is trying to do a git pull at the same > time?

Re: jenkins build hangs while trying to check for modifications on git
Cheers Jonathan, we don't have any branch, just about 7 tags at the moment, a team mate wrote a script to loop over git, doing few git operations and sometimes some of them fail. We will pass the issue to our ops, it might be network related. So for now we just do a build every 5 minutes, not super stable, not great but better than nothing.

Re: jenkins build hangs while trying to check for modifications on git
Antonio, Is this on a Windows box with more than one agent configured to run on it and possibly more than one agent is trying to do a git pull at the same time? If so, it may be ssh hanging on you. I recently went through this myself, and found the following reference a great help. http://darrell.mozingo.net/2011/09/29/painfully-slow-clone-speeds-with-msysgit-gitextensions/ Since I changed my ssh to the one from cygwin, I have had absolutely no git hangs (over probably 20K pulls), whereas before I was getting a hang about 2% of the time.

I had this problem in my setup. Our git repository has a very large number of branches and I discovered that limiting the number of branches the git plugin should consider sped it up a lot. However, since we needed to be able to have Jenkins build out of new branches as they are created, this was difficult to manage. I eventually gave up on the git plugin entirely and now do everything with direct git commands or scripts which call git commands. Unfortunately, the git plugin just doesn't seem to be able to scale efficiently to a large number of branches as git itself does. -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
