Description:

pydebsign 0.1.5

Status

Motivation
debsign is a command of devscripts that sign a Debian .changes and .dsc file pare using GPG,
the command cannot use in environment witout TTY, for example invokeking by CI.
I had tried to use debsign from subprocess module of Python as follow,
but entering passphrase prompt is always returned.
It was the same in the case of using gnupg-agent and keyring.:
>>> import subprocess
>>> import shlex
>>> command0 = 'echo -e "%s\n%s\n"' % (`passphrase`, `passphrase`)
>>> command1 = '/usr/bin/debsign -k %s %s' % (`keyid`, `.changes`)
>>> process0 = subprocess.Popen(shlex.split(command0),
... stdin=subprocess.PIPE,
... stdout=subprocess.PIPE,
... stderr=subprocess.PIPE)
>>> process1 = subprocess.Popen(shlex.split(command1),
... stdin=process0.stdout,
... stdout=subprocess.PIPE,
... stderr=subprocess.PIPE)
>>> stdout, stderr = process.communicate()
So, I decided to make a Python library to do the same behavior debsign.

Goal

It is enable to sign .changes and .dsc files with GPG without the input of interactive passphrase.
It can also be used by a user can not login shell on the CI, such as Jenkins.

Requires

Debian system, or the system derived from Debian.

Debian GNU/Linux Wheezy
Debian GNU/Linux Jessie/Sid
Ubuntu 14.04 LTS

Debian package as follows;

gnupg
dput
lintian
python (= python2.7) or python3

Python packages as follows;

python_gnupg (as debian package is python-gnupg or python3-gnupg)
python_debian (as debian package is python-debian or python3-debian)
chardet (as debian package is python-chardet or python3-chardet)

Usage
Generic usage;:
>>> from pydebsign import debsign
>>> debsign.debsign_process('/path/to/some.changes', passphrase='secretkey')
When use another GPG Keyring instead of default GPG keyring;:
>>> from pydebsign import debsign
>>> debsign.debsign_process('/path/to/some.changes', passphrase='secretkey',
... keyid='keyid', gnupghome='/path/to/gpghome')
