In commit 07e7dbf0d (gc: default aggressive depth to 50, 2016-08-11),
the default aggressive depth of git-gc has been changed to 50. While
git-config(1) has been updated to represent the new default value,
git-gc(1) still mentions the old value. This patch fixes it.

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.

git_config_parse_key() implements the validation and downcasing of
<section> and <variable> in "<section>[.<subsection>].<variable>"
configuration variable name. Move it (and helpers it uses) a bit up
so that it can be used by git_config_parse_parameter(), which is
used to check configuration settings that are given on the command
line (i.e. "git -c VAR=VAL cmd"), in a later patch.

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).

$ git config branch.side.remote colleague
However, "git remote rm" to remove the remote used in such a manner
fails with

because it assumes that a branch that has .remote defined must also
have .merge defined. Detect the "cannot unset because it is not set

Renaming the current branch adds an event to the current branch's log
and to HEAD's log. However, the logged entries differ. The entry in
the branch's log represents the entire renaming operation (the old and
new hash are identical), whereas the entry in HEAD's log represents
the deletion only (the new sha1 is null).
Extend replace_each_worktree_head_symref(), whose only caller is
branch_rename(), to take a reflog message argument. This allows the
creation of the new ref to be recorded in HEAD's log. As a result,
the renaming event is represented by two entries (a deletion and a
creation entry) in HEAD's log.
It's a bit unfortunate that the branch's log and HEAD's log now
represent the renaming event in different ways. Given that the
renaming operation is not atomic, the two-entry form is a more
accurate representation of the operation and is more useful for
debugging purposes if a failure occurs between the deletion and
creation events. It would make sense to move the branch's log to the
two-entry form, but this would involve changes to how the rename is
carried out and to how the update flags and reflogs are processed for
deletions, so it may not be worth the effort.

When the current branch is renamed with 'git branch -m/-M' or deleted
with 'git update-ref -m<msg> -d', the event is recorded in HEAD's log
with an empty message. In preparation for adding a more meaningful
message to HEAD's log in these cases, update delete_ref() to take a
message argument and pass it along to ref_transaction_delete().
Modify all callers to pass NULL for the new message argument; no
change in behavior is intended.
Note that this is relevant for HEAD's log but not for the deleted
ref's log, which is currently deleted along with the ref. Even if it
were not, an entry for the deletion wouldn't be present in the deleted
ref's log. files_transaction_commit() writes to the log if
REF_NEEDS_COMMIT or REF_LOG_ONLY are set, but lock_ref_for_update()
doesn't set REF_NEEDS_COMMIT for the deleted ref because REF_DELETING
is set. In contrast, the update for HEAD has REF_LOG_ONLY set by
split_head_update(), resulting in the deletion being logged.
