This patch adds an additional field `options` to scm_dict, which can be
used to provide additional information to the backends.
It implements a single new option for GitWrapper. This option allows
setting a custom git credentials wrapper. This can be useful if Pungi
needs to get files from a git repository that requires authentication.
The helper can be as simple as this (assuming the username is already
provided in the url):
#!/bin/sh
echo password=i-am-secret
The helper would need to be referenced by an absolute path from the
pungi configuration, or prefixed with ! to have git interpret it as a
shell script and look it up in PATH.
See https://git-scm.com/docs/gitcredentials for more details.
