"git clone" gave some progress messages to the standard output, not to
the standard error, and did not allow suppressing them with the
"--no-progress" option.

clone: always set transport options
clone: treat "checking connectivity" like other progress
clone: send diagnostic messages to stderr

A clone will always create a transport struct, whether we
are cloning locally or using an actual protocol. In the
local case, we only use the transport to get the list of
refs, and then transfer the objects out-of-band.
However, there are many options that we do not bother
setting up in the local case. For the most part, these are
noops, because they only affect the object-fetching stage
(e.g., the --depth option). However, some options do have a
visible impact. For example, giving the path to upload-pack
via "-u" does not currently work for a local clone, even
though we need upload-pack to get the ref list.
We can just drop the conditional entirely and set these
options for both local and non-local clones. Rather than
keep track of which options impact the object versus the ref
fetching stage, we can simply let the noops be noops (and
the cost of setting the options in the first place is not
high).
The one exception is that we also check that the transport
provides both a "get_refs_list" and a "fetch" method. We
will now be checking the former for both cases (which is
good, since a transport that cannot fetch refs would not
work for a local clone), and we tweak the conditional to
check for a "fetch" only when we are non-local.

When stderr does not point to a tty, we typically suppress
"we are now in this phase" progress reporting (e.g., we ask
the server not to send us "counting objects" and the like).
The new "checking connectivity" message is in the same vein,
and should be suppressed. Since clone relies on the
transport code to make the decision, we can simply sneak a
peek at the "progress" field of the transport struct. That
properly takes into account both the verbosity and progress
options we were given, as well as the result of isatty().
Note that we do not set up that progress flag for a local
clone, as we do not fetch using the transport at all. That's
acceptable here, though, because we also do not perform a
connectivity check in that case.

Putting messages like "Cloning into.." and "done" on stdout
is un-Unix and uselessly clutters the stdout channel. Send
them to stderr.
We have to tweak two tests to accommodate this:
1. t5601 checks for doubled output due to forking, and
doesn't actually care where the output goes; adjust it
to check stderr.
2. t5702 is trying to test whether progress output was
sent to stderr, but naively does so by checking
whether stderr produced any output. Instead, have it
look for "%", a token found in progress output but not
elsewhere (and which lets us avoid hard-coding the
progress text in the test).
This should not regress any scripts that try to parse the
current output, as the output is already internationalized
and therefore unstable.

"git shortlog" used to choke and die when there is a malformed commit
(e.g. missing authors); it now simply ignore such a commit and keeps
going.

Most of git's traversals are robust against minor breakages
in commit data. For example, "git log" will still output an
entry for a commit that has a broken encoding or missing
author, and will not abort the whole operation.
Shortlog, on the other hand, will die as soon as it sees a
commit without an author, meaning that a repository with
a broken commit cannot get any shortlog output at all.
Let's downgrade this fatal error to a warning, and continue
the operation.
We simply ignore the commit and do not count it in the total
(since we do not have any author under which to file it).
Alternatively, we could output some kind of "<empty>" record
to collect these bogus commits. It is probably not worth it,
though; we have already warned to stderr, so the user is
aware that such bogosities exist, and any placeholder we
came up with would either be syntactically invalid, or would
potentially conflict with real data.

"git ls-files -k" needs to crawl only the part of the working tree
that may overlap the paths in the index to find killed files, but
shared code with the logic to find all the untracked files, which
made it unnecessarily inefficient.

"ls-files -o" and "ls-files -k" both traverse the working tree down
to find either all untracked paths or those that will be "killed"
(removed from the working tree to make room) when the paths recorded
in the index are checked out. It is necessary to traverse the
working tree fully when enumerating all the "other" paths, but when
we are only interested in "killed" paths, we can take advantage of
the fact that paths that do not overlap with entries in the index
can never be killed.
The treat_one_path() helper function, which is called during the
recursive traversal, is the ideal place to implement an
optimization.
When we are looking at a directory P in the working tree, there are
three cases:
(1) P exists in the index. Everything inside the directory P in
the working tree needs to go when P is checked out from the
index.
(2) P does not exist in the index, but there is P/Q in the index.
We know P will stay a directory when we check out the contents
of the index, but we do not know yet if there is a directory
P/Q in the working tree to be killed, so we need to recurse.
(3) P does not exist in the index, and there is no P/Q in the index
to require P to be a directory, either. Only in this case, we
know that everything inside P will not be killed without
recursing.
Note that this helper is called by treat_leading_path() that decides
if we need to traverse only subdirectories of a single common
leading directory, which is essential for this optimization to be
correct. This caller checks each level of the leading path
component from shallower directory to deeper ones, and that is what
allows us to only check if the path appears in the index. If the
call to treat_one_path() weren't there, given a path P/Q/R, the real
traversal may start from directory P/Q/R, even when the index
records P as a regular file, and we would end up having to check if
any leading subpath in P/Q/R, e.g. P, appears in the index.

mark_edges_uninteresting(revs->commits, revs, ...);

revs related in any way?" when looking at mark_edges_uninteresting
implementation.

"git commit --author=$name" sets the author to one whose name
matches the given string from existing commits, when $name is not in
the "Name <e-mail>" format. However, it does not honor the mailmap
to use the canonical name for the author found this way.
Fix it by telling the logic to find a matching existing author to
honor the mailmap, and use the name and email after applying the
mailmap.

A Git-aware "connect" transport allows the "transport_take_over" to
redirect generic transport requests like fetch(), push_refs() and
get_refs_list() to the native Git transport handling methods. The
take-over process replaces transport->data with a fake data that
these method implementations understand.
While this hack works OK for a single request, it breaks when the
transport needs to make more than one requests. transport->data
that used to hold necessary information for the specific helper to
work correctly is destroyed during the take-over process.
One codepath that this matters is "git fetch" in auto-follow mode;
when it does not get all the tags that ought to point at the history
it got (which can be determined by looking at the peeled tags in the
initial advertisement) from the primary transfer, it internally
makes a second request to complete the fetch. Because "take-over"
hack has already destroyed the data necessary to talk to the
transport helper by the time this happens, the second request cannot
make a request to the helper to make another connection to fetch
these additional tags.
Mark such a transport as "cannot_reuse", and use a separate
transport to perform the backfill fetch in order to work around
this breakage.
Note that this problem does not manifest itself when running t5802,
because our upload-pack gives you all the necessary auto-followed
tags during the primary transfer. You would need to step through
"git fetch" in a debugger, stop immediately after the primary
transfer finishes and writes these auto-followed tags, remove the
tag references and repack/prune the repository to convince the
"find-non-local-tags" procedure that the primary transfer failed to
give us all the necessary tags, and then let it continue, in order
to trigger the bug in the secondary transfer this patch fixes.

Usually the upload-pack process running on the other side will give
us all the reachable tags we need during the primary object transfer
in do_fetch(). If that does not happen (e.g. the other side may be
running a third-party implementation of upload-pack), we will run
another fetch to pick up leftover tags that we know point at the
commits reachable from our updated tips.
Separate out the code to run this second fetch into a helper
function.

When we refuse to make an empty commit, we check whether we
are in a cherry-pick in order to give better advice on how
to proceed. We instruct the user to repeat the commit with
"--allow-empty" to force the commit, or to use "git reset"
to skip it and abort the cherry-pick.
In the case of a single cherry-pick, the distinction between
skipping and aborting is not important, as there is no more
work to be done afterwards. When we are using the sequencer
to cherry pick a series of commits, though, the instruction
is confusing: does it skip this commit, or does it abort the
rest of the cherry-pick?
It does skip, after which the user can continue the
cherry-pick. This is the right thing to be advising the user
to do, but let's make it more clear what will happen, both
by using the word "skip", and by mentioning that the rest of
the sequence can be continued via "cherry-pick --continue"
(whether we skip or take the commit).

Each caller of sha1_object_info_extended sets up an
object_info struct to tell the function which elements of
the object it wants to get. Until now, getting the type of
the object has always been required (and it is returned via
the return type rather than a pointer in object_info).
This can involve actually opening a loose object file to
determine its type, or following delta chains to determine a
packed file's base type. These effects produce a measurable
slow-down when doing a "cat-file --batch-check" that does
not include %(objecttype).
This patch adds a "typep" query to struct object_info, so
that it can be optionally queried just like size and
disk_size. As a result, the return type of the function is
no longer the object type, but rather 0/-1 for success/error.
As there are only three callers total, we just fix up each
caller rather than keep a compatibility wrapper:
1. The simpler sha1_object_info wrapper continues to
always ask for and return the type field.
2. The istream_source function wants to know the type, and
so always asks for it.
3. The cat-file batch code asks for the type only when
%(objecttype) is part of the format string.
On linux.git, the best-of-five for running:
$ git rev-list --objects --all >objects
$ time git cat-file --batch-check='%(objectsize:disk)'
on a fully packed repository goes from:
real 0m8.680s
user 0m8.160s
sys 0m0.512s
to:
real 0m7.205s
user 0m6.580s
sys 0m0.608s

A common use of "cat-file --batch-check" is to feed a list
of objects from "rev-list --objects" or a similar command.
In this instance, all of our input objects are 40-byte sha1
ids. However, cat-file has always allowed arbitrary revision
specifiers, and feeds the result to get_sha1().
Fortunately, get_sha1() recognizes a 40-byte sha1 before
doing any hard work trying to look up refs, meaning this
scenario should end up spending very little time converting
the input into an object sha1. However, since 798c35f
(get_sha1: warn about full or short object names that look
like refs, 2013-05-29), when we encounter this case, we
spend the extra effort to do a refname lookup anyway, just
to print a warning. This is further exacerbated by ca91993
(get_packed_ref_cache: reload packed-refs file when it
changes, 2013-06-20), which makes individual ref lookup more
expensive by requiring a stat() of the packed-refs file for
each missing ref.
With no patches, this is the time it takes to run:
$ git rev-list --objects --all >objects
$ time git cat-file --batch-check='%(objectname)' <objects
on the linux.git repository:
real 1m13.494s
user 0m25.924s
sys 0m47.532s
If we revert ca91993, the packed-refs up-to-date check, it
gets a little better:
real 0m54.697s
user 0m21.692s
sys 0m32.916s
but we are still spending quite a bit of time on ref lookup
(and we would not want to revert that patch, anyway, which
has correctness issues). If we revert 798c35f, disabling
the warning entirely, we get a much more reasonable time:
real 0m7.452s
user 0m6.836s
sys 0m0.608s
This patch does the moral equivalent of this final case (and
gets similar speedups). We introduce a global flag that
callers of get_sha1() can use to avoid paying the price for
the warning.

"git describe" takes a commit and gives it a name based on tags in
its neighbourhood. The command does take a commit-ish but when
given a tag that points at a commit, it should dereference the tag
before computing the name for the commit.
As the whole processing is internally delegated to name-rev, if we
unwrap tags down to the underlying commit when invoking name-rev, it
will make the name-rev issue an error message based on the unwrapped
object name (i.e. either 40-hex object name, or "$tag^0") that is
different from what the end-user gave to the command when the commit
cannot be described. Introduce an internal option --peel-tag to the
name-rev to tell it to unwrap a tag in its input from the command
line.

"git name-rev --stdin" has been fixed to convert an object name that
points at a tag to a refname of the tag. The codepath to handle its
command line arguments, however, fed the commit that the tag points
at to the underlying naming machinery.
With this fix, you will get this:
$ git name-rev --refs=tags/\* --name-only $(git rev-parse v1.8.3 v1.8.3^0)
v1.8.3
v1.8.3^0
which is the same as what you would get from the fixed "--stdin" variant:
$ git rev-parse v1.8.3 v1.8.3^0 | git name-rev --refs=tags/\* --name-only
v1.8.3
v1.8.3^0

"git name-rev" is supposed to convert given object names into
strings that name the same objects based on refs, that can be fed to
"git rev-parse" to get the same object names back, so the output for
the commit object v1.8.3^0 (i.e. the commit tagged as v1.8.3)
$ git rev-parse v1.8.3 v1.8.3^0 | git name-rev --stdin
8af06057d0c31a24e8737ae846ac2e116e8bafb9
edca4152560522a431a51fc0a06147fc680b5b18 (tags/v1.8.3^0)
has to have "^0" at the end, as "edca41" is a commit, not the tag
that references it. But we do not get anything for the tag object
(8af0605) itself.
This is because the command however did not bother to see if the
object is at the tip of some ref, and failed to convert a tag
object.
Teach it to show this instead:
$ git rev-parse v1.8.3 v1.8.3^0 | git name-rev --stdin
8af06057d0c31a24e8737ae846ac2e116e8bafb9 (tags/v1.8.3)

Introduce command check-mailmap, similar to check-attr and check-ignore,
which allows direct testing of .mailmap configuration.
As plumbing accessible to scripts and other porcelain, check-mailmap
publishes the stable, well-tested .mailmap functionality employed by
built-in Git commands. Consequently, script authors need not
re-implement .mailmap functionality manually, thus avoiding potential
quirks and behavioral differences.
