[Buildbot-devel] Problem with buildbot configuration for building debian packages

[joguerrero at cnti.gob.ve]

Hello everyone, my name is Francisco and I am new here =)

I'm setting a buildbot for building debian packages from a git 
repository.

So far I have configured the master and everything seems fine until I 
reach the steps for doing the real build. I build the packages by hand 
using this "recipe":

# export this variables to get the package name and its version

export PKGNAME=$(dpkg-parsechangelog | grep-dctrl -esSource . | awk -F' 
' '{print $2}')
export VERSION=$(dpkg-parsechangelog | grep-dctrl -esVersion . | awk -F' 
' '{print $2}' | sed 's/-.*//g')

# then i create the tar.gz using the variables above

tar --anchored --exclude-vcs --exclude "./debian" -cvzf ../$(echo 
$PKGNAME"_"$VERSION).orig.tar.gz --directory=$(pwd) ./

# and finally build the package

gbp buildpackage -tc --git-tag --git-retag -uc -us

Then I tried to "translate" the recipe to the steps in the configuration 
file of the master, like this:

...
f.addStep(SetPropertyFromCommand(command = "dpkg-parsechangelog | 
grep-dctrl -esSource . | awk -F' ' '{print $2}'", property = 
'packagename'))
f.addStep(SetPropertyFromCommand(command = "dpkg-parsechangelog | 
grep-dctrl -esVersion . | awk -F' ' '{print $2}' | sed 's/-.*//g'", 
property = 'origver'))

f.addStep(ShellCommand(command = WithProperties("tar --anchored 
--exclude-vcs --exclude './debian' -cvzf 
../%(packagename)s_%(origver)s.orig.tar.gz --directory=$(pwd) ./")))
...

the last step (generate the tar.gz) fails and it's the main reason why 
i'm stucked with this. I tried with this variants:

#f.addStep(ShellCommand(command = ['tar', '--anchored', '--exclude-vcs', 
'--exclude', "'./debian'", "-cvzf",
# WithProperties("../%(packagename)s_%(origver)s.orig.tar.gz"), 
'--directory=$(pwd)', './"']))

#f.addStep(ShellCommand(command = ['gbp', 'buildpackage', '-us', '-uc', 
'-tc', '--git-tag', '--git-retag'], workdir='build/'+package, 
env={'DIST': 'jessie', 'ARCH': a}))

but none of them worked for me. You can see the traceback here:

I used 'SetPropertyFromCommand' because I thought it could be a 
convenient way to capture and store the name and version variables for 
later use with the 'WithProperties' method, but now I think something is 
failing there. I am not sure if the variables are actually being stored. 
Is there a way to verify this?

Maybe there are more things that I am doing wrong?

I hope you could give me some insights about the correct configuration 
of buildbot for the tasks mentioned or point me in the right direction 
to get this working.
