[RFC PATCH v2 00/16] Return of smart HTTP

["Shawn O. Pearce" <spearce@spearce.org>]

The series has gotten a lot larger since my last posting, but I have
what appears to be a fully working client *AND* server implementation
for both fetch and push, and the client should be supporting deeping
shallow repositories over the smart variant of HTTP.

I've dropped the documentation patch from the series for now as
I have quite a few edits queued up from folks in the last round
(thanks for those!) that I have not yet applied.  So there is no
point in sending that particular patch again.

This series is still lacking:

* The HTTP protocol documentation
* Manual page for git-http-backend
* Tests for the smart http transport code (existing tests pass)
* ack from the CC'd maintainers  :-)

For those who are really curious, this applies to 'master' and I'm
running my local server under Apache with this as my configuration:

 -- httpd.conf <8--
 LoadModule cgi_module /usr/libexec/apache2/mod_cgi.so
 LoadModule alias_module /usr/libexec/apache2/mod_alias.so
 LoadModule env_module /usr/libexec/apache2/mod_env.so

 ServerRoot /home/spearce/test
 ErrorLog error_log

 $ httpd -f httpd.conf
 $ git clone --bare foo.git /home/spearce/test/www/test.git
