pydebsign 0.1.4

yet another library of debsign

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')
