and stream experts, Gump needs you

[Stefan Bodewig <bo...@apache.org>]

Hi Peter, Martijn and Matt ;-)

I know you've been poking around the way streams get pumped in Execute
a few times.  It seems that in a wierd constellation of Python calling
Ant and Ant calling <exec> (or forked <java>) the last process stalls.

Some details can be found in this thread
<http://marc.theaimsgroup.com/?t=112109511300004&r=1&w=2>, although
I'm not sure it carries enough information to pin down the problem.

Cheers

        Stefan

This is the best Leo could come up with

If you think you'd rather have access to vmgump, I can try to arrange
that.

I don't know about simple :-)

###########################################################################
# Note the gump3 install on vmgump is documented at
#   http://wiki.apache.org/gump/VmgumpConfig
# so if you want to reproduce locally, just follow the instructions
# labelled as being related to gump3
ssh vmgump.apache.org
sudo bash
su - gump
cd /usr/local/gump/gump3/Gump3
svn up
$EDITOR pygump/python/gump/plugins/java/builder.py
# change the line that reads
#
#        self._do_run_command(ant, args, projectpath, no_cleanup=True)
# to
#        self._do_run_command(ant, args, projectpath, no_cleanup=False)
#
# save file.

# this file is regenerated by xalan's java_cup, so get rid of it
rm \
pygump/work/gump3-test/xml/xml-xalan/java/src/org/apache/xalan/xsltc/compiler/XPathParser.java

crontab -l | grep gump3
# get the line that looks like its the gump3 test run,
# and run that, perhaps modified a little, eg perhaps
/bin/bash gump run --do-updates --do-builds --debug \
   --local-module-name=gump3-packages

# you can then rerun just the xalan build using something like this
rm \
pygump/work/gump3-test/xml/xml-xalan/java/src/org/apache/xalan/xsltc/compiler/XPathParser.java
/bin/bash gump run --do-builds --debug \
   --local-module-name=gump3-packages -p xalan

After my recently-confessed failure to get pipes
working in Ant (Windows' fault I swear) I hardly
consider myself an expert... :) .  With that
disclaimer having been made, I could try to take a
look if I had a ready-made test environment....
