391a3c70c3 doc: revisions: give headings for the two and three dot notations
While there, also break out the other shorthand notations and
add a title for the revision range summary (which also appears
in git-rev-parse, so keep it mixed case).

We do not quote the notation within the headings as the asciidoc ->
docbook -> groff man viewer toolchain, particularly the docbook-groff
step, does not cope with two font changes, failing to return the heading
font to bold after the quotation of the notation.

54ba5a1a16 hashmap: clarify that hashmap_entry can safely be discarded
The API documentation said that the hashmap_entry structure to be
embedded in the caller's structure is to be treated as opaque, which
left the reader wondering if it can safely be discarded when it no
longer is necessary.  If the hashmap_entry structure had references
to external resources such as allocated memory or an open file
descriptor, merely free(3)ing the containing structure (when the
caller's structure is on the heap) or letting it go out of scope
(when it is on the stack) would end up leaking the external
resource.

Document that there is no need for hashmap_entry_clear() that
corresponds to hashmap_entry_init() to give the API users a little
bit of peace of mind.

642833db78 date: add "unix" format
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.

1a2a1e8eb9 date: document and test "raw-local" mode
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".

The actual shortening rules aren't that interesting and
probably not worth getting into (I gloss over them here as
"shortened for human readability"). But the fact that %gD
shows whatever you gave on the command line is subtle and
worth mentioning. Since most people will feed a shortened
refname in the first place, it otherwise makes it hard to
understand the difference between the two.

We document that asking for HEAD@{now} will switch the
output to show HEAD@{timestamp}, but not that specifying
`--date` has a similar effect, or that it can be overridden
with HEAD@{0}. Let's do so.

These rules come from 794151e (reflog-walk: always make
HEAD@{0} show indexed selectors, 2012-05-04), though that is
simply the culmination of years of these heuristics growing
organically.

2b68222d72 doc/rev-list-options: clarify "commit@{Nth}" for "-g" option
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
bonus, that lets us drop some asciidoc quoting.

83558686ce receive-pack: send keepalives during quiet periods
After a client has sent us the complete pack, we may spend
some time processing the data and running hooks. If the
client asked us to be quiet, receive-pack won't send any
progress data during the index-pack or connectivity-check
steps. And hooks may or may not produce their own progress
output. In these cases, the network connection is totally
silent from both ends.

Git itself doesn't care about this (it will wait forever),
but other parts of the system (e.g., firewalls,
load-balancers, etc) might hang up the connection. So we'd
like to send some sort of keepalive to let the network and
the client side know that we're still alive and processing.

We can use the same trick we did in 05e9515 (upload-pack:
send keepalive packets during pack computation, 2013-09-08).
Namely, we will send an empty sideband data packet every `N`
seconds that we do not relay any stderr data over the
sideband channel. As with 05e9515, this means that we won't
bother sending keepalives when there's actual progress data,
but will kick in when it has been disabled (or if there is a
lull in the progress data).

The concept is simple, but the details are subtle enough
that they need discussing here.

Before the client sends us the pack, we don't want to do any
keepalives. We'll have sent our ref advertisement, and we're
waiting for them to send us the pack (and tell us that they
support sidebands at all).

While we're receiving the pack from the client (or waiting
for it to start), there's no need for keepalives; it's up to
them to keep the connection active by sending data.
Moreover, it would be wrong for us to do so. When we are the
server in the smart-http protocol, we must treat our
connection as half-duplex. So any keepalives we send while
receiving the pack would potentially be buffered by the
webserver. Not only does this make them useless (since they
would not be delivered in a timely manner), but it could
actually cause a deadlock if we fill up the buffer with
keepalives. (It wouldn't be wrong to send keepalives in this
phase for a full-duplex connection like ssh; it's simply
pointless, as it is the client's responsibility to speak).

As soon as we've gotten all of the pack data, then the
client is waiting for us to speak, and we should start
keepalives immediately. From here until the end of the
connection, we send one any time we are not otherwise
sending data.

But there's a catch. Receive-pack doesn't know the moment
we've gotten all the data. It passes the descriptor to
index-pack, who reads all of the data, and then starts
resolving the deltas. We have to communicate that back.

To make this work, we instruct the sideband muxer to enable
keepalives in three phases:

  1. In the beginning, not at all.

  2. While reading from index-pack, wait for a signal
     indicating end-of-input, and then start them.

  3. Afterwards, always.

The signal from index-pack in phase 2 has to come over the
stderr channel which the muxer is reading. We can't use an
extra pipe because the portable run-command interface only
gives us stderr and stdout.

Stdout is already used to pass the .keep filename back to
receive-pack. We could also send a signal there, but then we
would find out about it in the main thread. And the
keepalive needs to be done by the async muxer thread (since
it's the one writing sideband data back to the client). And
we can't reliably signal the async thread from the main
thread, because the async code sometimes uses threads and
sometimes uses forked processes.

Therefore the signal must come over the stderr channel,
where it may be interspersed with other random
human-readable messages from index-pack. This patch makes
the signal a single NUL byte.  This is easy to parse, should
not appear in any normal stderr output, and we don't have to
worry about any timing issues (like seeing half the signal
bytes in one read(), and half in a subsequent one).

This is a bit ugly, but it's simple to code and should work
reliably.

Another option would be to stop using an async thread for
muxing entirely, and just poll() both stderr and stdout of
index-pack from the main thread. This would work for
index-pack (because we aren't doing anything useful in the
main thread while it runs anyway). But it would make the
connectivity check and the hook muxers much more
complicated, as they need to simultaneously feed the
sub-programs while reading their stderr.

The index-pack phase is the only one that needs this
signaling, so it could simply behave differently than the
other two. That would mean having two separate
implementations of copy_to_sideband (and the keepalive
code), though. And it still doesn't get rid of the
signaling; it just means we can write a nicer message like
"END_OF_INPUT" or something on stdout, since we don't have
to worry about separating it from the stderr cruft.

One final note: this signaling trick is only done with
index-pack, not with unpack-objects. There's no point in
doing it for the latter, because by definition it only kicks
in for a small number of objects, where keepalives are not
as useful (and this conveniently lets us avoid duplicating
the implementation).

434ea3cdad rev-list: add optional progress reporting
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.

90cf590f53 fsck: optionally show more helpful info for broken links
When reporting broken links between commits/trees/blobs, it would be
quite helpful at times if the user would be told how the object is
supposed to be reachable.

With the new --name-objects option, git-fsck will try to do exactly
that: name the objects in a way that shows how they are reachable.

For example, when some reflog got corrupted and a blob is missing that
should not be, the user might want to remove the corresponding reflog
entry. This option helps them find that entry: `git fsck` will now
report something like this:

	broken link from    tree b5eb6ff...  (refs/stash@{<date>}~37:)
	              to    blob ec5cf80...

77a9745d19 push options: {pre,post}-receive hook learns about push options
The environment variable GIT_PUSH_OPTION_COUNT is set to the number of
push options sent, and GIT_PUSH_OPTION_{0,1,..} is set to the transmitted
option.

The code is not executed as the push options are set to NULL, nor is the
new capability advertised.

There was some discussion back and forth how to present these push options
to the user as there are some ways to do it:

Keep all options in one environment variable
============================================
+ easiest way to implement in Git
- This would make things hard to parse correctly in the hook.

Put the options in files instead,
filenames are in GIT_PUSH_OPTION_FILES
======================================
+ After a discussion about environment variables and shells, we may not
  want to put user data into an environment variable (see [1] for example).
+ We could transmit binaries, i.e. we're not bound to C strings as
  we are when using environment variables to the user.
+ Maybe easier to parse than constructing environment variable names
  GIT_PUSH_OPTION_{0,1,..} yourself
- cleanup of the temporary files is hard to do reliably
- we have race conditions with multiple clients pushing, hence we'd need
  to use mkstemp. That's not too bad, but still.

Use environment variables, but restrict to key/value pairs
==========================================================
(When the user pushes a push option `foo=bar`, we'd
GIT_PUSH_OPTION_foo=bar)
+ very easy to parse for a simple model of push options
- it's not sufficient for more elaborate models, e.g.
  it doesn't allow doubles (e.g. cc=reviewer@email)

Present the options in different environment variables
======================================================
(This is implemented)
* harder to parse as a user, but we have a sample hook for that.
- doesn't allow binary files
+ allows the same option twice, i.e. is not restrictive about
  options, except for binary files.
+ doesn't clutter a remote directory with (possibly stale)
  temporary files

As we first want to focus on getting simple strings to work
reliably, we go with the last option for now. If we want to
do transmission of binaries later, we can just attach a
'side-channel', e.g. "any push option that contains a '\0' is
put into a file instead of the environment variable and we'd
have new GIT_PUSH_OPTION_FILES, GIT_PUSH_OPTION_FILENAME_{0,1,..}
environment variables".
