Subject: [PATCH] tag: add tag.gpgSign config option to force all tags be GPG-signed
Date: Thu, 26 Oct 2017 21:55:16 +0200 [thread overview]
Message-ID: <20171026195516.3354-1-tigran.mkrtchyan@desy.de> (raw)
In some workflows we have no control on how git command is executed,
however a signed tags are required.
The new config-file option tag.gpgSign enforces signed tags. Additional
command line option --no-gpg-sign is added to disable such behavior if
needed. E.g.:
$ git tag -m "commit message"
will generate a GPG signed tag if tag.gpgSign option is true, while
$ git tag --no-gpg-sign -m "commit message"
will skip the signing step.
