Re: [PATCH 1/3] Add support for external programs for handling native fetches

Hi,

On Sat, 25 Jul 2009, Daniel Barkalow wrote:

transport_get() can call transport_shim_init() to have list and
fetch-ref operations handled by running a separate program as:

 git shim-<something> <remote> [<url>]

This program then accepts, on its stdin, "list" and "fetch <hex>
<name>" commands; the former prints out a list of available refs and
either their hashes or what they are symreefs to, while the latter
fetches them into the local object database and prints a newline when done.

This is similar to, but different from, my git-vcs-* stuff; this one 
expects the helper to be able to look up sha1s for refs efficiently, and 
to be able to fetch objects directly into the local object database 
without fast-import. On the otherhand, it should be sufficiently general 
to allow arbitrary methods for moving the data around.

I wonder if this cannot be integrated into the git-vcs stuff; after all, 
they do pretty much the same things, except that the vcs helpers are 
pretty dumb, and the shim helpers are not as dumb.

I could imagine that the name of the helper could reveal its capability to 
act as a shim helper: git-vcs-shim-http
