Hudson build freezes after writing 60K to disk

Question

Environment:

• WinXP SP3
• Git: 1.7.0.2.msysgit.0
• Hudson 1.367
• Git server on local network with Gitosis and GitWeb

We are preparing to migrate from SVN to Git and have lots of working builds using SVN. Initial attempt at a Hudson Git build used the Git plugin. I start the build and it would get to the git clone phase. Exactly 60k of disk space would be written to the .git directory and then Hudson/Git would freeze. Hudson just sits on the build waiting forever.

I disabled the Git plugin, instead I kick off a Python script through the Hudson Execute Windows Batch Command facility. It runs and freezes when the .git directory uses exactly 60k of disk space.

I captured the batch file that Hudson builds and run it on the command line and it runs to completion.

One idea I had was that the job was blocking on stdout or stderr, so I redirected both to NULL. Nope, still hit the 60k barrier. Then I tried to kick off git clone with the -q flag (quiet). Still no.

Hudson logs shows precious little. Here is a sample from one run:
Jul 28, 2010 5:07:56 PM hudson.model.Run run

My next step is to move Hudson to Linux, although I would rather do that sometime in the future. Does anyone have any ideas on how to fix this (with or without the Git plug-in) on Windows?

Answer 1

Does Git uses some config files that are user specific? If so It might be a permissioning problem. Most people seem to run Hudson as a server using the local_system account. You have two options, first you can run hudson as a different user and create the necessary files by log in interactively and setup git or you can identify the missing files and copy them to the workspace of the local_system account. For the correct path to the local system workspace, you need to google a little bit. It is usually somewhere in the Windows folder.

EDIT: Did you check the Hudson logs?
