This series has three parts:
01 - 03: Use an external program to fetch with curl. This improves
performance of scripts that call a lot of simple git
programs on systems where libcurl has a lot of dependencies
substantially, and introduces a standard format for external
helpers. Since the push side of http support is still
invoked from a custom helper program by the core transport
code, http support cannot yet be made a completely separate
package, but this is a step in that direction. Since the
previous version, this section has a few type fixes and in
more consistent about its use of strbufs.
04 - 10: Allow the external helper to import data from a foreign
system. This system may not use URLs at all, or may not use
them in a way that distinguishes the usage from git's
usage. The core code has to be able to deal with only
getting the values of refs after they have been imported,
not when they are simply listed, and deciding based on a
flag and the name whether to import them. The helper code
may (to this point) avoid doing anything to require the
local system to be git, rather than any other gfi-supporting
system (although there is no support for limiting the
generated history to things a particular system can
represent). This series has changed substantially since
previous versions, centered around sharing code with the
native helper methods, supporting code for the cvs and p4
helpers as they have evolved, and various fixes. Johan
Herland wrote the bulk of the last patch, including
specifying the command; I removed some portions of his patch
that were made unnecessary by changes to this series (and
rebasing it on the previous series).
11 - 13: Draft external helper for cvs. The first two patches are
directly by Johan Herland, and are included unchanged. The
final patch is the changes needed for the difference in API
between the original "vcs helper" series and the current
04-10. In order to get this part to work, the "jh/notes"
branch in pu is required, although the patches apply without
it.
As a separate series, I will be sending a new version of my p4 helper,
in addition to handling for an "export" command which is not yet
nailed down, since it is only supported by one helper and is not
agnostic as to the source system (like the import command can be).
Daniel Barkalow (10):
Add support for external programs for handling native fetches
Use an external program to implement fetching with curl
Use a function to determine whether a remote is valid
