svnstat script
- by Kyle Hodgson
So I'm building out a shell script to check out all of our relevant svn repositories for analysis in svnstat. I've gotten all of this to work manually, now I'm writing up a bash script in cygwin on my Vista laptop, as I intend to move this to a Linux server at some point.
Edit: I gave up on this and wrote a simple .bat script. I'll figure out the Linux deployment some other way.
Edit: added the sleep 30 and svn log commands. I can tell now, with the svn log command, that it's not getting to the svn log ... this time, it did Applications, and ran the log, and then check out Database, and froze. I'll put the sleep 30 before and after the log this time.
co2.sh
#!/bin/bash
function checkout {
mkdir $1
svn checkout svn://dev-server/$1 $1
svn log --verbose --xml >> svn.log $1
sleep 30
}
cd /cygdrive/c/Users/My\ User/Documents/Repos/wc
checkout Applications
checkout Database
checkout WebServer/www.mysite.com
checkout WebServer/anotherhost.mysite.com
checkout WebServer/AnotherApp
checkout WebServer/thirdhost.mysite.com
checkout WebServer/fourthhost.mysite.com
checkout WebServer/WebServices
It works, for the most part - but for some reason it has a tendency to stop working after a few repositories, usually right after finishing a repository before going to the next one. When it fails, it will not recover on its own. I've tried commenting out the svn line, it goes in and creates all the directories just fine when I do that - so its not that.
I'm looking for direction as well as direct advice. Cygwin has been very stable for me, but I did start using the native rxvt instead of "bash in a cmd.exe window" recently. I don't think that's the problem, as I've left top on remote systems running all night and rxvt didn't seem to mind. Also I haven't done any bash scripting in cygwin so I suppose this might not be recommended; though I can't see why not. I don't want all of WebServer, hence me only checking out certain folders like that.
What I suspect is that something is hanging up the svn checkout. Any ideas here?
Edit: this time when I hit ctrl+z to cancel out, I forgot I was on Windows and typed ps to see if the job was still running; and as you can see there are lots of svn processes hanging around... strange.

Here's an strace on the PID of the hung svn program, it's been like this for hours. Looks like its just doing nothing. I keep suspecting that some interruption on the server is causing this; does svn have a locking mechanism I'm not aware of?
