[Buildbot-devel] Redirect buildstep output to a file.

[Schmiedlin, Joshua]

One of the nightly build steps I would like to run is a tool called
statSVN.  This takes a svn log file as one of its input parameters.  I
currently have a batch file that does this for me, but I would like to
convert that batch file into buildbot build steps.

Note: This is running on a windowsxp machine and it won't be migrated to
unix or linux.

The steps from the batch file are as follows:
1 - Update buildslave's working copy of svn
2 - svn log > svnlog.log
3 - statSVN -outputdir c:\blah svnlog.log   <--- where svnlog.log is its
input.

My problem is with step two.  I have been unsuccessful at getting the
buildslave to actually run the second step.  If I split the command into
a list then it doesn't like the '>'.  If I run it as a string then I get
the following in my log file.

	C:\WINDOWS\system32\cmd.exe /c svn log -v --xml -r 368:HEAD >
gppSVN.log
	 in dir c:\BuildBotSlave\gppDocGen\build (timeout 1200 secs)
	 watching logfiles {}
	 argv: ['C:\\WINDOWS\\system32\\cmd.exe', '/c', 'svn log -v
--xml -r 368:HEAD > gppSVN.log']

Any thoughts on how I can go about redirecting the stdout of the svn log
command to a file that is local on the slave machine?

Thanks,

Joshua L. Schmiedlin
