pydebsign is a yet another library of debsign¶
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')
