I am not certain why the cvstagdiff was hanging, but I was able to achieve the
same functionality that I was looking for by using the CVS task and passing it
the "diff" as a command line option. For example:
<cvs dest="${cvs.checkout.dir}" output="${cvs.checkout.dir}/out1.txt"
error="${cvs.checkout.dir}/out2.txt">
<commandline>
<argument line="diff --brief"/>
</commandline>
</cvs>
That is good enough for what I am trying to do; plus since I am using the cvs
task instead of the exec task, I am assuming that my ANT script should be
platform independent (i.e. run on both windows and unix).
Thanks for your help,

Nothing that looks unusual there. The cvs command was forked, and the
stream pumper on another thread is reading the output of the command.
In the past (months? years?), some people complained cvstagdiff was
taking an inordinate amount of time compared to the same command on
the command line. You haven't said anything on how long the command
takes on the CLI, and whether this time changes or not with <exec>.
You could try testing on a smaller repo or inside a subset of your
repo.
If someone the command slows down, how long have you waited before
asserting it hangs? Doing the test on a very small repo might allow it
to complete in a "reasonnable" time.
Also, try thread dumps at different times, to see if you can get a
different stack-trace.

I'd try CVSNT. I've always used it on Windows, and used to do
cvstagdiff with it (a long time ago). I get it from TortoiseCVS,
rather than the CVSNT stand-alone install.

I'm running out of ideas. If nothing works, modify cvstagdiff to work
off a cvs diff file output separately by a different command, and
combine it with an <exec>.
There's a remote possibility that your server outputs something that
throws off the parsing code of cvstagdiff, but the thread dump does
not point to such an issue. --DD
