Subject: http-push: enable "proactive auth"
X-Git-Tag: v1.7.8.2~14^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=a4ddbc33d7906f0e10c68c140a9a1003d9715a77;p=git.git

http-push: enable "proactive auth"

Before commit 986bbc08, git was proactive about asking for
http passwords. It assumed that if you had a username in
your URL, you would also want a password, and asked for it
before making any http requests.

However, this could interfere with the use of .netrc (see
986bbc08 for details). And it was also unnecessary, since
the http fetching code had learned to recognize an HTTP 401
and prompt the user then. Furthermore, the proactive prompt
could interfere with the usage of .netrc (see 986bbc08 for
details).

Unfortunately, the http push-over-DAV code never learned to
recognize HTTP 401, and so was broken by this change. This
patch does a quick fix of re-enabling the "proactive auth"
strategy only for http-push, leaving the dumb http fetch and
smart-http as-is.
