In one test, we use "git checkout --orphan HEAD" to create
an unborn branch. Confusingly, the resulting branch is named
"refs/heads/HEAD". The original probably meant something
like:
git checkout --orphan orphaned-branch HEAD
Let's just use "orphaned-branch" here to make this less
confusing. Putting HEAD in the second argument is already
implied.

Add a function for appending the canonized absolute pathname of a given
path to a strbuf. It keeps the existing contents intact, as expected of
a function of the strbuf_add() family, while avoiding copying the result
if the given strbuf is empty. It's more consistent with the rest of the
strbuf API than strbuf_realpath(), which it's wrapping.
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.

The parsing of one-shot assignments of configuration variables that
come from the command line historically was quite loose and allowed
anything to pass. It also downcased everything in the variable name,
even a three-level <section>.<subsection>.<variable> name in which
the <subsection> part must be treated in a case sensitive manner.
Existing git_config_parse_key() helper is used to parse the variable
name that comes from the command line, i.e. "git config VAR VAL",
and handles these details correctly. Replace the strbuf_tolower()
call in git_config_parse_parameter() with a call to it to correct
both issues. git_config_parse_key() does a bit more things that are
not necessary for the purpose of this codepath (e.g. it allocates a
separate buffer to return the canonicalized variable name because it
takes a "const char *" input), but we are not in a performance-critical
codepath here.

When we read user.name and user.email from a config file,
they go into strbufs. When a caller asks ident_default_name()
for the value, we fallback to auto-detecting if the strbuf
is empty.
That means that explicitly setting an empty string in the
config is identical to not setting it at all. This is
potentially confusing, as we usually accept a configured
value as the final value.

An ident name consisting of only "crud" characters (like
whitespace or punctuation) is effectively the same as an
empty one, because our strbuf_addstr_without_crud() will
remove those characters.
We reject an empty name when formatting a strict ident, but
don't notice an all-crud one because our check happens
before the crud-removal step.
We could skip past the crud before checking for an empty
name, but let's make it a separate code path, for two
reasons. One is that we can give a more specific error
message. And two is that unlike a blank name, we probably
don't want to kick in the fallback-to-username behavior.

If we see an empty name, we complain about and mention the
matching email in the error message (to give it some
context). However, the "email" pointer may be NULL here if
we were planning to fill it in later from ident_default_email().
This was broken by 59f929596 (fmt_ident: refactor strictness
checks, 2016-02-04). Prior to that commit, we would look up
the default name and email before doing any other actions.
So one solution would be to go back to that.
However, we can't just do so blindly. The logic for handling
the "!email" condition has grown since then. In particular,
looking up the default email can die if getpwuid() fails,
but there are other errors that should take precedence.
Commit 734c7789a (ident: check for useConfigOnly before
auto-detection of name/email, 2016-03-30) reordered the
checks so that we prefer the error message for
useConfigOnly.
Instead, we can observe that while the name-handling depends
on "email" being set, the reverse is not true. So we can
simply set up the email variable first.
This does mean that if both are bogus, we'll complain about
the email before the name. But between the two, there is no
reason to prefer one over the other.

By default, we tell curl to use CURLAUTH_ANY, which does not
limit its set of auth methods. However, this results in an
extra round-trip to the server when authentication is
required. After we've fed the credential to curl, it wants
to probe the server to find its list of available methods
before sending an Authorization header.
We can shortcut this by limiting our http_auth_methods by
what the server told us it supports. In some cases (such as
when the server only supports Basic), that lets curl skip
the extra probe request.
The end result should look the same to the user, but you can
use GIT_TRACE_CURL to verify the sequence of requests:
GIT_TRACE_CURL=1 \
git ls-remote https://example.com/repo.git \
2>&1 >/dev/null |
egrep '(Send|Recv) header: (GET|HTTP|Auth)'
Before this patch, hitting a Basic-only server like
github.com results in:
Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1
Recv header: HTTP/1.1 401 Authorization Required
Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1
Recv header: HTTP/1.1 401 Authorization Required
Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1
Send header: Authorization: Basic <redacted>
Recv header: HTTP/1.1 200 OK
And after:
Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1
Recv header: HTTP/1.1 401 Authorization Required
Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1
Send header: Authorization: Basic <redacted>
Recv header: HTTP/1.1 200 OK
The possible downsides are:
- This only helps for a Basic-only server; for a server
with multiple auth options, curl may still send a probe
request to see which ones are available (IOW, there's no
way to say "don't probe, I already know what the server
will say").
- The http_auth_methods variable is global, so this will
apply to all further requests. That's acceptable for
Git's usage of curl, though, which also treats the
credentials as global. I.e., in any given program
invocation we hit only one conceptual server (we may be
redirected at the outset, but in that case that's whose
auth_avail field we'd see).
