Re: ant script just hang when checking out of CVS [Similar problem with cvstagdiff]

I just found out from my system admin that I cannot
setup private/public key for my machine to connect to
the CVS server, due to internal security policies.
But anyway, it just occured to me and I am wondering
whether the problem that I am having with cvstagdiff
has anything to do with ssh waiting for the password.
After all I am perfectly able to execute the following
from my ANT script:
<cvs package="myProject" dest="${basedir}/temp" />
The above command works and it is able to successfully
checkout the myProject package into the temp folder.
On the other hand, executing the cvstagdiff in the
same ANT script does not work and it just hangs:
<cvstagdiff
destfile="${basedir}/temp/tagdiff.xml"
package="myProject"
startDate="09/15/2007"
endDate="09/24/2007"
failonerror="true"
quiet="false"
/>
Recall from my previous e-mail that I am setting the
username and password in the CVSROOT environment
variable:
CVSROOT=:ssh;username=MyUserName;password=MyPassword;hostname=some.servername.com:/opt/cvs
So I don't understand why the cvs and the cvstagdiff
tags act differently. Why does the cvs tag work with
the password being set in the CVSROOT environment
variable, while the cvstagdiff tag doesn't???

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.
> Thanks for the suggestions,
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

Very true. Thanks for the reminder.

That's an excellent suggestion. I went ahead and
triggered a JVM thread dump on the hanging Ant
process. I have copied and pasted the thread dump at
the end of this e-mail message.

I've already tried this, as I've already indicated in
my previous e-mail. It works perfectly from the
command line.

Thanks for the suggestion. I tried this. It works from
the <exec>.

No need to remind a programmer. Google is the first
place that I consult even before posting to the
mailing list. It is much easier to search google than
it is to compose a detailed message explaining a
problem, then posting it to the mailing list.
Thanks for the suggestions,

P.S. I ran the my ant script in verbose mode, and then
I triggered a thread dump. Here is the output:

"Request a fix" won't get you anywhere. There are a few things you can
explore on your own:
1) Where does it hang? Google how to trigger a thread dump of your JVM
and post it. If there's really a hang, that may give so clues.
2) Provide relevant information: version of CVS client? version of CVS
server? JVM? Ant version? OS? etc...This may not get you an answer
still, but at least you're willing to give enough details for someone
to help you.
3) Try the same command line (a) at the command line, then (b) in Ant,
in <exec>, to see if the <exec> version, which uses Ant, somehow
works when <cvstagdiff> doesn't.
4) Show that you've done some research on your own. Google is your friend.
In general, people will help right away if they know the answer
already, or can find it out easily. If not, which should someone else
invest time in helping you for free? Sometimes some question simply
don't interest the community too... --DD

So far I have not received any responses to my
question. Was my question too difficult to answer?
Let me try to re-phrase my question.
Why does the cvstagdiff Ant task NOT work when I have
the CVSROOT environment variable set with the
password? Is this a bug in Ant? Should I request a
fix for it?
