This patch series adds support for a new receive.denyCurrentBranch setting
to update the working directory (which must be clean, i.e. there must not be
any uncommitted changes) when pushing into the current branch.
The scenario in which the 'updateInstead' setting became a boon in this
developer's daily work is when trying to get a bug fix from a Windows
computer, a virtual machine, or when getting a bug fix from a user's machine
onto his main machine (in all of those cases it is only possible to connect
via ssh in one direction, but not in the reverse direction). It also comes
in handy when updating a live web site via push (in which case a clean
working directory is an absolute must).
Interdiff vs v4 below diffstat.
Johannes Schindelin (1):
Add another option for receive.denyCurrentBranch
