[PATCH 0/5] Foreign VCS as remote config

Daniel Barkalow· Mar 25, 2009, 03:04 UTC · lore

This series, like my previous series, makes it possible to set up a git config like:

[remote "origin"]
        vcs = p4
        port = localhost:1666
        ignoreCodeline = //depot/projects/oof-1.0
        codeline = //depot/projects/foo-1.0
        fetch = refs/p4/depot/projects/*:refs/remotes/origin/*

And then "git fetch origin" will actually incrementally import a p4 project.

The main difference from the previous series, aside from a nicer version of the p4 importer that can use the free-as-in-beer C++ API, is the fact that the only diff for a builtin command is to builtin-clone, which just needs to make a copy of a const struct before passing it to a function that can now change it.

Parts 1 and 2 are potentially useful for other other protocols transporting git data, and could be applied now. Part 3 creates the option and makes it not work at all. Part 4 is the same old API, and transport.c code to use it. Part 5 is my p4 example.

There's still the oddity that foreign systems that don't use a URL will lead to struct remotes that don't look valid to some git code that expects the URL field to be filled.

Daniel Barkalow (5):
  Allow late reporting of fetched hashes
  Document details of transport function APIs
  Add option for using a foreign VCS
  Draft of API for git-vcs-*, transport.c code to use it.
  p4 example of git-vcs API for fetch direction
