This is a newly-generated and reorganized replacement for db/foreign-scm.
It applies to recent next.
I'd be particularly interested in feedback from people working on hg
import/export programs, since that's probably a better user for this code
than my p4 helper, and also doesn't rely on closed-source code.
The overall goal is to be able to configure a remote in some way and then
use "git fetch/pull" and "git push" to interact with other version control
systems, instead of having interface scripts with their own command lines,
additional instructions, etc.
The main changes are:
(1) The remote does not need to use a url for the location
(2) The helper is rearranged to be able to do multiple operations in a
single execution, allowing it to keep a single open connection for
listing the refs and then fetching them.
(3) There is some preliminary support for exporting data to the foreign
system.
Also, the p4 example helper is significantly more capable and efficient
than the previously-posted one.
Daniel Barkalow (7):
Add specification of git-vcs-* helper programs
Use a function to determine whether a remote is valid
Allow fetch to modify refs
Allow programs to not depend on remotes having urls
Add a config option for remotes to specify a foreign vcs
Add a transport implementation using git-vcs-* helpers
Implement git-vcs-p4
