http.c supports HTTP redirects of the form
http://foo/info/refs?service=git-upload-pack
-> http://anything
-> http://bar/info/refs?service=git-upload-pack
(that is to say, as long as the Git part of the path and the query
string is preserved in the final redirect destination, the intermediate
steps can have any URL). However, if one of the intermediate steps
results in an HTTP exception, a confusing "unable to update url base
from redirection" message is printed instead of a Curl error message
with the HTTP exception code.
This was introduced by 2 commits. Commit c93c92f ("http: update base
URLs when we see redirects", 2013-09-28) introduced a best-effort
optimization that required checking if only the "base" part of the URL
differed between the initial request and the final redirect destination,
but it performed the check before any HTTP status checking was done. If
something went wrong, the normal code path was still followed, so this
did not cause any confusing error messages until commit 6628eb4 ("http:
always update the base URL for redirects", 2016-12-06), which taught
http to die if the non-"base" part of the URL differed.
Therefore, teach http to check the HTTP status before attempting to
check if only the "base" part of the URL differed. This commit teaches
http_request_reauth to return early without updating options->base_url
upon an error; the only invoker of this function that passes a non-NULL
"options" is remote-curl.c (through "http_get_strbuf"), which only uses
options->base_url for an informational message in the situations that
this commit cares about (that is, when the return value is not HTTP_OK).
The included test checks that the redirect scheme at the beginning of
this commit message works, and that returning a 502 in the middle of the
redirect scheme produces the correct result. Note that this is different
from the test in commit 6628eb4 ("http: always update the base URL for
redirects", 2016-12-06) in that this commit tests that a Git-shaped URL
(http://.../info/refs?service=git-upload-pack) works, whereas commit
6628eb4 tests that a non-Git-shaped URL
(http://.../info/refs/foo?service=git-upload-pack) does not work (even
though Git is processing that URL) and is an error that is fatal, not
silently swallowed.

The gitdiffcore documentation quotes the term "Complete Rewrites" in
headers for no real gain. This would make sense if the term could be
easily confused if not properly grouped together. But actually, the term
is quite obvious and thus does not really need any quoting, especially
regarding that it is not used anywhere else.
But more importanly, this brings up a bug when rendering man pages: when
trying to render quotes inside of a section header, we end up with
quotes which have been misaligned to the end of line. E.g.
diffcore-break: For Splitting Up Complete Rewrites
--------------------------------------------------
renders as
DIFFCORE-BREAK: FOR SPLITTING UP COMPLETE REWRITES""
, which is obviously wrong. While this is fixable for the man pages by
using double-quotes (e.g. ""COMPLETE REWRITES""), this again breaks it
for our generated HTML pages.
So fix the issue by simply dropping quotes inside of section headers,
which is currently only done for the term "Complete Rewrites".

Change the tests that fail to when we run the test suite as root, due

The GNU cvs package has an optional compile-time CVS_BADROOT
flag. When compiled with this flag "cvs commit" will refuse to commit
anything as root. On my Debian box this isn't compiled in[1] in, but

I've run all the t/t*cvs*.sh tests, and these are the only two that
fail. For some reason e.g. t9402-git-cvsserver-refs.sh still works as
root despite doing "cvs commit", I haven't dug into why.
This commit is technically being overzealous, we could do better by
making a mock cvs commit as root and run the tests if that works, but
I don't see any compelling reason to bend over backwards to run these
tests in all cases, just skipping them as root seems good enough.

Also add a semantic patch demonstrating its intended usage and apply it

This variable needs to be specified to make some types of
non-basic authentication work, but ideally this would just
work out of the box for everyone.
However, simply setting it to "1" by default introduces an
extra round-trip for cases where it _isn't_ useful. We end
up sending a bogus empty credential that the server rejects.
Instead, let's introduce an automatic mode, that works like
this:
1. We won't try to send the bogus credential on the first
request. We'll wait to get an HTTP 401, as usual.
2. After seeing an HTTP 401, the empty-auth hack will kick
in only when we know there is an auth method available
that might make use of it (i.e., something besides
"Basic" or "Digest").
That should make it work out of the box, without incurring
any extra round-trips for people hitting Basic-only servers.
This _does_ incur an extra round-trip if you really want to
use "Basic" but your server advertises other methods (the
emptyauth hack will kick in but fail, and then Git will
actually ask for a password).
The auto mode may incur an extra round-trip over setting
http.emptyauth=true, because part of the emptyauth hack is
to feed this blank password to curl even before we've made a
single request.

Adding comments after a tag in the body is a common practise (e.g. in
the Linux kernel) and git-send-email has been supporting this for years
by removing any trailing cruft after the address.
After some recent changes, any trailing comment is now instead appended
to the recipient name (with some random white space inserted) resulting
in undesirable noise in the headers, for example:
CC: "# 3 . 3 . x : 1b9508f : sched : Rate-limit newidle" <stable@vger.kernel.org>
Revert to the earlier behaviour of discarding anything after the (first)
address in a tag while parsing the body.
Note that multiple addresses after are still allowed after a command
line switch (and in a CC header field).
Also note that --suppress-cc=self was never honoured when using multiple
addresses in a tag.

The parse_config_key() function was introduced to make it
easier to match "section.subsection.key" variables. It also
handles the simpler "section.key", and the caller is
responsible for distinguishing the two from its
out-parameters.
Most callers who _only_ want "section.key" would just use a
strcmp(var, "section.key"), since there is no parsing
required. However, they may still use parse_config_key() if
their "section" variable isn't a constant (an example of
this is in parse_hide_refs_config).
Using the parse_config_key is a bit clunky, though:
const char *subsection;
int subsection_len;
const char *key;
if (!parse_config_key(var, section, &subsection, &subsection_len, &key) &&
!subsection) {
/* matched! */
}
Instead, let's treat a NULL subsection as an indication that
the caller does not expect one. That lets us write:
const char *key;
if (!parse_config_key(var, section, NULL, NULL, &key)) {
/* matched! */
}
Existing callers should be unaffected, as passing a NULL
subsection would currently segfault.
