A new date format "--date=human" that morphs its output depending
on how far the time is from the current time has been introduced.
"--date=auto" can be used to use this new format when the output is
going to the pager or to the terminal and otherwise the default
format.

Display date and time information in a format similar to how people
write dates in other contexts. If the year isn't specified then, the
reader infers the date is given is in the current year.
By not displaying the redundant information, the reader concentrates
on the information that is different. The patch reports relative dates
based on information inferred from the date on the machine running the
git command at the time the command is executed.
While the format is more useful to humans by dropping inferred
information, there is nothing that makes it actually human. If the
'relative' date format wasn't already implemented then using
'relative' would have been appropriate.

Implement positive values for <depth> in the tree:<depth> filter. The
exact semantics are described in Documentation/rev-list-options.txt.
The long-term goal at the end of this is to allow a partial clone to
eagerly fetch an entire directory of files by fetching a tree and
specifying <depth>=1. This, for instance, would make a build operation
fast and convenient. It is fast because the partial clone does not need
to fetch each file individually, and convenient because the user does
not need to supply a sparse-checkout specification.
Another way of considering this feature is as a way to reduce
round-trips, since the client can get any number of levels of
directories in a single request, rather than wait for each level of tree
objects to come back, whose entries are used to construct a new request.

It appears we try to nest open blocks, but that does not work well with
Asciidoctor, which fails to indent the inner blocks. As a result, they
do not visually seem to relate (as much) to the preceding paragraph as
they should. Drop the outer blocks to fix the rendering of the inner
ones. Asciidoc renders identically before and after this patch, both
man-pages and html.
This also makes Asciidoctor stop rendering a literal '+' before "Under
--pretty=oneline ..." in the manuals for git-log and git-rev-list.

Operations on promisor objects make sense in the context of only a
small subset of the commands that internally use the revisions
machinery, but the "--exclude-promisor-objects" option were taken

Teach list-objects the "tree:0" filter which allows for filtering
out all tree and blob objects (unless other objects are explicitly
specified by the user). The purpose of this patch is to allow smaller
partial clones.
The name of this filter - tree:0 - does not explicitly specify that
it also filters out all blobs, but this should not cause much confusion
because blobs are not at all useful without the trees that refer to
them.
I also considered only:commits as a name, but this is inaccurate because
it suggests that annotated tags are omitted, but actually they are
included.
The name "tree:0" allows later filtering based on depth, i.e. "tree:1"
would filter out all but the root tree and blobs. In order to avoid
confusion between 0 and capital O, the documentation was worded in a
somewhat round-about way that also hints at this future improvement to
the feature.

Teach rev-list to support termination of an object traversal at any
object from a promisor remote (whether one that the local repo also has,
or one that the local repo knows about because it has another promisor
object that references it).
This will be used subsequently in gc and in the connectivity check used
by fetch.
For efficiency, if an object is referenced by a promisor object, and is
in the local repo only as a non-promisor object, object traversal will
not stop there. This is to avoid building the list of promisor object
references.
(In list-objects.c, the case where obj is NULL in process_blob() and
process_tree() do not need to be changed because those happen only when
there is a conflict between the expected type and the existing object.
If the object doesn't exist, an object will be synthesized, which is
fine.)

Teach rev-list to use the filtering provided by the
traverse_commit_list_filtered() interface to omit
unwanted objects from the result.
Object filtering is only allowed when one of the "--objects*"
options are used.
When the "--filter-print-omitted" option is used, the omitted
objects are printed at the end. These are marked with a "~".
This option can be combined with "--quiet" to get a list of
just the omitted objects.
Add t6112 test.
In the future, we will introduce a "partial clone" mechanism
wherein an object in a repo, obtained from a remote, may
reference a missing object that can be dynamically fetched from
that remote once needed. This "partial clone" mechanism will
have a way, sometimes slow, of determining if a missing link
is one of the links expected to be produced by this mechanism.
This patch introduces handling of missing objects to help
debugging and development of the "partial clone" mechanism,
and once the mechanism is implemented, for a power user to
perform operations that are missing-object aware without
incurring the cost of checking if a missing link is expected.

The functionality to list tree objects in the order they were seen
while traversing the commits will be used in one of the next commits,
where we teach `git describe` to describe not only commits, but blobs, too.
The change in list-objects.c is rather minimal as we'll be re-using
the infrastructure put in place of the revision walking machinery. For
example one could expect that add_pending_tree is not called, but rather
commit->tree is directly passed to the tree traversal function. This
however requires a lot more code than just emptying the queue containing
trees after each commit.

There is no portable way to pass timezone information to strftime. Add
parameters for timezone offset and name to strbuf_addftime and let it
handle the timezone-related format specifiers %z and %Z internally.
Callers can opt out for %Z by passing NULL as timezone name. %z is
always handled internally -- this helps on Windows, where strftime would
expand it to a timezone name (same as %Z), in violation of POSIX.
Modifiers are not handled, e.g. %Ez is still passed to strftime.
Use an empty string as timezone name in show_date (the only current
caller) for now because we only have the timezone offset in non-local
mode. POSIX allows %Z to resolve to an empty string in case of missing
information.

Add a short -P option as a synonym for the longer --perl-regexp, for
consistency with the options the corresponding grep invocations
accept.
This was intentionally omitted in commit 727b6fc3ed ("log --grep:
accept --basic-regexp and --perl-regexp", 2012-10-03) for unspecified
future use.
Make it consistent with "grep" rather than to keep it open for future
use, and to avoid the confusion of -P meaning different things for
grep & log, as is the case with the -G option.
As noted in the aforementioned commit the --basic-regexp option can't
have a corresponding -G argument, as the log command already uses that
for -G<regex>.

Stop promising in our grep & rev-list options documentation that we're
always going to be using libpcre when given the --perl-regexp option.
Instead talk about using "Perl-compatible regular expressions" and
using these types of patterns using "a compile-time dependency".
Saying "libpcre" means that we're talking about libpcre.so, which is
always going to be v1. This change is part of an ongoing saga to add
support for libpcre2, which comes with PCRE v2.
In the future we might use some completely unrelated library to
provide perl-compatible regular expression support. By wording the
documentation differently and not promising any specific version of
PCRE or even PCRE at all we have more wiggle room to change the
implementation.

We already have "--date=raw", which is a Unix epoch
timestamp plus a contextual timezone (either the author's or
the local). But one may not care about the timezone and just
want the epoch timestamp by itself. It's not hard to parse
the two apart, but if you are using a pretty-print format,
you may want git to show the "finished" form that the user
will see.
We can accomodate this by adding a new date format, "unix",
which is basically "raw" without the timezone.

The "raw" format shows a Unix epoch timestamp, but with a
timezone tacked on. The timestamp is not _in_ that zone, but
it is extra information about the time (by default, the zone
the author was in).
The documentation claims that "raw-local" does not work. It
does, but the end result is rather subtle. Let's describe it
in better detail, and test to make sure it works (namely,
the epoch time doesn't change, but the zone does).
While we are rewording the documentation in this area, let's
not use the phrase "does not work" for the remaining option,
"--date=relative". It's vague; do we accept it or not? We do
accept it, but it has no effect (which is a reasonable
outcome). We should also refer to the option not as
"--relative" (which is the historical synonym, and does not
take "-local" at all), but as "--date=relative".

We document that asking for HEAD@{now} will switch the

with HEAD@{0}. Let's do so.

When "log -g" shows "HEAD@{1}", "HEAD@{2}", etc, calling
that "commit@{Nth}" is not really accurate. The "HEAD" part
is really the refname. By saying "commit", a reader may
misunderstand that to mean something related to the specific
commit we are showing, not the ref whose reflog we are
traversing.
While we're here, let's also switch these instances to use
literal backticks, as our style guide recommends. As a

It's easy to ask rev-list to do a traversal that may takes
many seconds (e.g., by calling "--objects --all"). In theory
you can monitor its progress by the output you get to
stdout, but this isn't always easy.
Some operations, like "--count", don't make any output until
the end.
And some callers, like check_everything_connected(), are
using it just for the error-checking of the traversal, and
throw away stdout entirely.
This patch adds a "--progress" option which can be used to
give some eye-candy for a user waiting for a long traversal.
This is just a rev-list option and not a regular traversal
option, because it needs cooperation from the callbacks in
builtin/rev-list.c to do the actual count.

Most of our "--date" modes are about the format of the date:
which items we show and in what order. But "--date=local" is
a bit of an oddball. It means "show the date in the normal
format, but using the local timezone". The timezone we use
is orthogonal to the actual format, and there is no reason
we could not have "localized iso8601", etc.
This patch adds a "local" boolean field to "struct
date_mode", and drops the DATE_LOCAL element from the
date_mode_type enum (it's now just DATE_NORMAL plus
local=1). The new feature is accessible to users by adding
"-local" to any date mode (e.g., "iso-local"), and we retain
"local" as an alias for "default-local" for backwards
compatibility.

Because "--graph" is about connected history while --no-walk is
about discrete points, it does not make sense to allow these two
options at the same time. [1]
This change makes a few calls to "show --graph" fail in t4052, but
asking to show one commit with graph is a nonsensical thing to do.
Thus, tests on "show --graph" in t4052 have been removed [2,3].
Same tests on "show" without --graph option have already been tested
in 4052.
3 testcases have been added to test this patch.
