This commit message is long and has lots of background and
numbers. The summary is: the current default of 250 doesn't
save much space, and costs CPU. It's not a good tradeoff.
Read on for details.
The "--aggressive" flag to git-gc does three things:
1. use "-f" to throw out existing deltas and recompute from
scratch
2. use "--window=250" to look harder for deltas
3. use "--depth=250" to make longer delta chains
Items (1) and (2) are good matches for an "aggressive"
repack. They ask the repack to do more computation work in
the hopes of getting a better pack. You pay the costs during
the repack, and other operations see only the benefit.
Item (3) is not so clear. Allowing longer chains means fewer
restrictions on the deltas, which means potentially finding
better ones and saving some space. But it also means that
operations which access the deltas have to follow longer
chains, which affects their performance. So it's a tradeoff,
and it's not clear that the tradeoff is even a good one.
The existing "250" numbers for "--aggressive" come
originally from this thread:
http://public-inbox.org/git/alpine.LFD.0.9999.0712060803430.13796@woody.linux-foundation.org/
where Linus says:
So when I said "--depth=250 --window=250", I chose those
numbers more as an example of extremely aggressive
packing, and I'm not at all sure that the end result is
necessarily wonderfully usable. It's going to save disk
space (and network bandwidth - the delta's will be re-used
for the network protocol too!), but there are definitely
downsides too, and using long delta chains may
simply not be worth it in practice.
There are some numbers in that thread, but they're mostly
focused on the improved window size, and measure the
improvement from --depth=250 and --window=250 together.
E.g.:
http://public-inbox.org/git/9e4733910712062006l651571f3w7f76ce64c6650dff@mail.gmail.com/
talks about the improved run-time of "git-blame", which
comes from the reduced pack size. But most of that reduction
is coming from --window=250, whereas most of the extra costs
come from --depth=250. There's a link in that thread showing
that increasing the depth beyond 50 doesn't seem to help
much with the size:
https://vcscompare.blogspot.com/2008/06/git-repack-parameters.html
but again, no discussion of the timing impact.
In an earlier thread from Ted Ts'o which discussed setting
the non-aggressive default (from 10 to 50):
http://public-inbox.org/git/20070509134958.GA21489%40thunk.org/
we have more numbers, with the conclusion that going past 50
does not help size much, and hurts the speed of normal
operations.
So from that, we might guess that 50 is actually a sweet
spot, even for aggressive, if we interpret aggressive to
"spend time now to make a better pack". It is not clear that
"--depth=250" is actually a better pack. It may be slightly
_smaller_, but it carries a run-time penalty.
Here are some more recent timings I did to verify that. They
show three things:
- the size of the resulting pack (so disk saved to store,
bandwidth saved on clones/fetches)
- the cost of "rev-list --objects --all", which shows the
effect of the delta chains on trees (commits typically
don't delta, and the command doesn't touch the blobs at
all)
- the cost of "log -Sfoo", which will additionally access
each blob
All cases were repacked with "git repack -adf --depth=$d
--window=250" (so basically, what would happen if we tweaked
the "gc --aggressive" default depth).
The timings are all wall-clock best-of-3. The machine itself
has plenty of RAM compared to the repositories (which is
probably typical of most workstations these days), so we're
really measuring CPU usage, as the whole thing will be in
disk cache after the first run.
The core.deltaBaseCacheLimit is at its default of 96MiB.
It's possible that tweaking it would have some impact on the
tests, as some of them (especially "log -S" on a large repo)
are likely to overflow that. But bumping that carries a
run-time memory cost, so for these tests, I focused on what
we could do just with the on-disk pack tradeoffs.
Each test is done for four depths: 250 (the current value),
50 (the current default that tested well previously), 100
(to show something on the larger side, which previous tests
showed was not a good tradeoff), and 10 (the very old
default, which previous tests showed was worse than 50).
Here are the numbers for linux.git:
depth | size | % | rev-list | % | log -Sfoo | %
-------+-------+-------+----------+--------+-----------+-------
250 | 967MB | n/a | 48.159s | n/a | 378.088 | n/a
100 | 971MB | +0.4% | 41.471s | -13.9% | 342.060 | -9.5%
50 | 979MB | +1.2% | 37.778s | -21.6% | 311.040s | -17.7%
10 | 1.1GB | +6.6% | 32.518s | -32.5% | 279.890s | -25.9%
and for git.git:
depth | size | % | rev-list | % | log -Sfoo | %
-------+-------+-------+----------+--------+-----------+-------
250 | 48MB | n/a | 2.215s | n/a | 20.922s | n/a
100 | 49MB | +0.5% | 2.140s | -3.4% | 17.736s | -15.2%
50 | 49MB | +1.7% | 2.099s | -5.2% | 15.418s | -26.3%
10 | 53MB | +9.3% | 2.001s | -9.7% | 12.677s | -39.4%
You can see that that the CPU savings for regular operations improves as we
decrease the depth. The savings are less for "rev-list" on a smaller repository
than they are for blob-accessing operations, or even rev-list on a larger
repository. This may mean that a larger delta cache would help (though setting
core.deltaBaseCacheLimit by itself doesn't).
But we can also see that the space savings are not that great as the depth goes
higher. Saving 5-10% between 10 and 50 is probably worth the CPU tradeoff.
Saving 1% to go from 50 to 100, or another 0.5% to go from 100 to 250 is
probably not.

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).

In the "remote -> local" line, if either ref is a substring of the
other, the common part in the other string is replaced with "*". For
example
abc -> origin/abc
refs/pull/123/head -> pull/123
become
abc -> origin/*
refs/*/head -> pull/123
Activated with fetch.output=compact.
For the record, this output is not perfect. A single giant ref can
push all refs very far to the right and likely be wrapped around. We
may have a few options:
- exclude these long lines smarter
- break the line after "->", exclude it from column width calculation
- implement a new format, { -> origin/}foo, which makes the problem
go away at the cost of a bit harder to read
- reverse all the arrows so we have "* <- looong-ref", again still
hard to read.

When upload-pack serves a client request, it turns to
pack-objects to do the heavy lifting of creating a
packfile. There's no easy way to intercept the call to
pack-objects, but there are a few good reasons to want to do
so:
1. If you're debugging a client or server issue with
fetching, you may want to store a copy of the generated
packfile.
2. If you're gathering data from real-world fetches for
performance analysis or debugging, storing a copy of
the arguments and stdin lets you replay the pack
generation at your leisure.
3. You may want to insert a caching layer around
pack-objects; it is the most CPU- and memory-intensive
part of serving a fetch, and its output is a pure
function[1] of its input, making it an ideal place to
consolidate identical requests.
This patch adds a simple "hook" interface to intercept calls
to pack-objects. The new test demonstrates how it can be
used for debugging (using it for caching is a
straightforward extension; the tricky part is writing the
actual caching layer).
This hook is unlike the normal hook scripts found in the
"hooks/" directory of a repository. Because we promise that
upload-pack is safe to run in an untrusted repository, we
cannot execute arbitrary code or commands found in the
repository (neither in hooks/, nor in the config). So
instead, this hook is triggered from a config variable that
is explicitly ignored in the per-repo config.
The config variable holds the actual shell command to run as
the hook. Another approach would be to simply treat it as a
boolean: "should I respect the upload-pack hooks in this
repo?", and then run the script from "hooks/" as we usually
do. However, that isn't as flexible; there's no way to run a
hook approved by the site administrator (e.g., in
"/etc/gitconfig") on a repository whose contents are not
trusted. The approach taken by this patch is more
fine-grained, if a little less conventional for git hooks
(it does behave similar to other configured commands like
diff.external, etc).
[1] Pack-objects isn't _actually_ a pure function. Its
output depends on the exact packing of the object
database, and if multi-threading is used for delta
compression, can even differ racily. But for the
purposes of caching, that's OK; of the many possible
outputs for a given input, it is sufficient only that we
output one of them.

With many incremental imports, small packs become highly
inefficient due to the need to readdir scan and load many
indices to locate even a single object. Frequent repacking and
consolidation may be prohibitively expensive in terms of disk
I/O, especially in large repositories where the initial packs
were aggressively optimized and marked with .keep files.
In those cases, users may be better served with loose objects
and relying on "git gc --auto".
This changes the default behavior of fast-import for small
imports found in test cases, so adjustments to t9300 were
necessary.

On Unix (and Linux), files and directories whose names start with a dot
are usually not shown by default. This convention is used by Git: the
.git/ directory should be left alone by regular users, and only accessed
through Git itself.
On Windows, no such convention exists. Instead, there is an explicit flag
to mark files or directories as hidden.
In the early days, Git for Windows did not mark the .git/ directory (or
for that matter, any file or directory whose name starts with a dot)
hidden. This lead to quite a bit of confusion, and even loss of data.
Consequently, Git for Windows introduced the core.hideDotFiles setting,
with three possible values: true, false, and dotGitOnly, defaulting to
marking only the .git/ directory as hidden.
The rationale: users do not need to access .git/ directly, and indeed (as
was demonstrated) should not really see that directory, either. However,
not all dot files should be hidden by default, as e.g. Eclipse does not
show them (and the user would therefore be unable to see, say, a
.gitattributes file).
In over five years since the last attempt to bring this patch into core
Git, a slightly buggy version of this patch has served Git for Windows'
users well: no single report indicated problems with the hidden .git/
directory, and the stream of problems caused by the previously non-hidden
.git/ directory simply stopped. The bugs have been fixed during the
process of getting this patch upstream.
Note that there is a funny quirk we have to pay attention to when
creating hidden files: we use Win32's _wopen() function which
transmogrifies its arguments and hands off to Win32's CreateFile()
function. That latter function errors out with ERROR_ACCESS_DENIED (the
equivalent of EACCES) when the equivalent of the O_CREAT flag was passed
and the file attributes (including the hidden flag) do not match an
existing file's. And _wopen() accepts no parameter that would be
transmogrified into said hidden flag. Therefore, we simply try again
without O_CREAT.
A slightly different method is required for our fopen()/freopen()
function as we cannot even *remove* the implicit O_CREAT flag.
Therefore, we briefly mark existing files as unhidden when opening them
via fopen()/freopen().
The ERROR_ACCESS_DENIED error can also be triggered by opening a file
that is marked as a system file (which is unlikely to be tracked in
Git), and by trying to create a file that has *just* been deleted and is
awaiting the last open handles to be released (which would be handled
better by the "Try again?" logic, a story for a different patch series,
though). In both cases, it does not matter much if we try again without
the O_CREAT flag, read: it does not hurt, either.
For details how ERROR_ACCESS_DENIED can be triggered, see

Change the hardcoded lookup for .git/hooks/* to optionally lookup in
$(git config core.hooksPath)/* instead.
This is essentially a more intrusive version of the git-init ability to
specify hooks on init time via init templates.
The difference between that facility and this feature is that this can
be set up after the fact via e.g. ~/.gitconfig or /etc/gitconfig to
apply for all your personal repositories, or all repositories on the
system.
I plan on using this on a centralized Git server where users can create
arbitrary repositories under /gitroot, but I'd like to manage all the
hooks that should be run centrally via a unified dispatch mechanism.

We introduce a way to send custom HTTP headers with all requests.
This allows us, for example, to send an extra token from build agents
for temporary access to private repositories. (This is the use case that
triggered this patch.)
This feature can be used like this:
git -c http.extraheader='Secret: sssh!' fetch $URL $REF
Note that `curl_easy_setopt(..., CURLOPT_HTTPHEADER, ...)` takes only
a single list, overriding any previous call. This means we have to
collect _all_ of the headers we want to use into a single list, and
feed it to cURL in one shot. Since we already unconditionally set a
"pragma" header when initializing the curl handles, we can add our new
headers to that list.
For callers which override the default header list (like probe_rpc),
we provide `http_copy_default_headers()` so they can do the same
trick.

patient reviews.

The patch hunk selector of add--interactive knows how ask
git for colorized diffs, and correlate them with the
uncolored diffs we apply. But there's not any way for
somebody who uses a diff-filter tool like contrib's
diff-highlight to see their normal highlighting.
This patch lets users define an arbitrary shell command to
pipe the colorized diff through. The exact output shouldn't
matter (since we just show the result to humans) as long as
it is line-compatible with the original diff (so that
hunk-splitting can split the colorized version, too).
I left two minor issues with the new system that I don't
think are worth fixing right now, but could be done later:
1. We only filter colorized diffs. Theoretically a user
could want to filter a non-colorized diff, but I find
it unlikely in practice. Users who are doing things
like diff-highlighting are likely to want color, too.
2. add--interactive will re-colorize a diff which has been
hand-edited, but it won't have run through the filter.
Fixing this is conceptually easy (just pipe the diff
through the filter), but practically hard to do without
using tempfiles (it would need to feed data to and read
the result from the filter without deadlocking; this
raises portability questions with respect to Windows).
I've punted on both issues for now, and if somebody really
cares later, they can do a patch on top.

It used to be that:
git config --global user.email "(none)"
was a viable way for people to force themselves to set user.email in

email address, targeting different email addresses for different
clones, as it barred git from creating a commit unless the user.email
config was set in the per-repo config to the correct email address.
A recent change, 19ce497c (ident: keep a flag for bogus
default_email, 2015-12-10), however, declared that an explicitly
configured user.email is not bogus, no matter what its value is, so

The git-over-rsync protocol is inefficient and broken, and
has been for a long time. It transfers way more objects than
it needs (grabbing all of the remote's "objects/",
regardless of which objects we need). It does its own ad-hoc
parsing of loose and packed refs from the remote, but
doesn't properly override packed refs with loose ones,
leading to garbage results (e.g., expecting the other side
to have an object pointed to by a stale packed-refs entry,
or complaining that the other side has two copies of the
refs[1]).
This latter breakage means that nobody could have
successfully pulled from a moderately active repository
since cd547b4 (fetch/push: readd rsync support, 2007-10-01).
We never made an official deprecation notice in the release
notes for git's rsync protocol, but the tutorial has marked
it as such since 914328a (Update tutorial., 2005-08-30).
And on the mailing list as far back as Oct 2005, we can find
Junio mentioning it as having "been deprecated for quite
some time."[2,3,4]. So it was old news then; cogito had
deprecated the transport in July of 2005[5] (though it did
come back briefly when Linus broke git-http-pull!).
Of course some people professed their love of rsync through
2006, but Linus clarified in his usual gentle manner[6]:
> Thanks! This is why I still use rsync, even though
> everybody and their mother tells me "Linus says rsync is
> deprecated."
No. You're using rsync because you're actively doing
something _wrong_.
The deprecation sentiment was reinforced in 2008, with a
mention that cloning via rsync is broken (with no fix)[7].
Even the commit porting rsync over to C from shell (cd547b4)
lists it as deprecated! So between the 10 years of informal
warnings, and the fact that it has been severely broken
since 2007, it's probably safe to simply remove it without
further deprecation warnings.

When we know that mtime on directory as given by the environment
is usable for the purpose of untracked cache, we may want the
untracked cache to be always used without any mtime test or
kernel name check being performed.
Also when we know that mtime is not usable for the purpose of
untracked cache, for example because the repo is shared over a
network file system, we may want the untracked-cache to be
automatically removed from the index.
Allow the user to express such preference by setting the
'core.untrackedCache' configuration variable, which can take
'keep', 'false', or 'true' and default to 'keep'.
When read_index_from() is called, it now adds or removes the
untracked cache in the index to respect the value of this
variable. So it does nothing if the value is `keep` or if the
variable is unset; it adds the untracked cache if the value is
`true`; and it removes the cache if the value is `false`.
`git update-index --[no-|force-]untracked-cache` still adds the
untracked cache to, or removes it, from the index, but this
shows a warning if it goes against the value of
core.untrackedCache, because the next time the index is read
the untracked cache will be added or removed if the
configuration is set to do so.
Also `--untracked-cache` used to check that the underlying
operating system and file system change `st_mtime` field of a
directory if files are added or deleted in that directory. But
because those tests take a long time, `--untracked-cache` no
longer performs them. Instead, there is now
`--test-untracked-cache` to perform the tests. This change
makes `--untracked-cache` the same as `--force-untracked-cache`.
This last change is backward incompatible and should be
mentioned in the release notes.

Currently, the only way to pass proxy credentials to curl is by including them
in the proxy URL. Usually, this means they will end up on disk unencrypted, one
way or another (by inclusion in ~/.gitconfig, shell profile or history). Since
proxy authentication often uses a domain user, credentials can be security
sensitive; therefore, a safer way of passing credentials is desirable.
If the configured proxy contains a username but not a password, query the
credential API for one. Also, make sure we approve/reject proxy credentials
properly.
For consistency reasons, add parsing of http_proxy/https_proxy/all_proxy
environment variables, which would otherwise be evaluated as a fallback by curl.
Without this, we would have different semantics for git configuration and
environment variables.

The --recurse-submodules command line parameter has existed for some
time but it has no config file equivalent.
Following the style of the corresponding parameter for git fetch, let's
invent push.recurseSubmodules to provide a default for this
parameter. This also requires the addition of --recurse-submodules=no to
allow the configuration to be overridden on the command line when
required.
The most straightforward way to implement this appears to be to make
push use code in submodule-config in a similar way to fetch.

If you hide a hierarchy of refs using the transfer.hideRefs
config, there is no way to later override that config to
"unhide" it. This patch implements a "negative" hide which
causes matches to immediately be marked as unhidden, even if
another match would hide it. We take care to apply the
matches in reverse-order from how they are fed to us by the
config machinery, as that lets our usual "last one wins"
config precedence work (and entries in .git/config, for
example, will override /etc/gitconfig).
So you can now do:
$ git config --system transfer.hideRefs refs/secret
$ git config transfer.hideRefs '!refs/secret/not-so-secret'
to hide refs/secret in all repos, except for one public bit
in one specific repo. Or you can even do:
$ git clone \
-u "git -c transfer.hiderefs="!refs/foo" upload-pack" \
remote:repo.git
to clone remote:repo.git, overriding any hiding it has
configured.
There are two alternatives that were considered and
rejected:
1. A generic config mechanism for removing an item from a
list. E.g.: (e.g., "[transfer] hideRefs -= refs/foo").
This is nice because it could apply to other
multi-valued config, as well. But it is not nearly as
flexible. There is no way to say:
[transfer]
hideRefs = refs/secret
hideRefs = refs/secret/not-so-secret
Having explicit negative specifications means we can
override previous entries, even if they are not the
same literal string.
2. Adding another variable to override some parts of
hideRefs (e.g., "exposeRefs").
This solves the problem from alternative (1), but it
cannot easily obey the normal config precedence,
because it would use two separate lists. For example:
[transfer]
hideRefs = refs/secret
exposeRefs = refs/secret/not-so-secret
hideRefs = refs/secret/not-so-secret/no-really-its-secret
With two lists, we have to apply the "expose" rules
first, and only then apply the "hide" rules. But that
does not match what the above config intends.
Of course we could internally parse that to a single
list, respecting the ordering, which saves us having to
invent the new "!" syntax. But using a single name
communicates to the user that the ordering _is_
important. And "!" is well-known for negation, and
should not appear at the beginning of a ref (it is
actually valid in a ref-name, but all entries here
should be fully-qualified, starting with "refs/").

This is extremely handy in case of legacy repositories where it would
cause more pain to change incorrect objects than to live with them
(e.g. a duplicate 'author' line in an early commit object).
The intended use case is for server administrators to inspect objects
that are reported by `git push` as being too problematic to enter the
repository, and to add the objects' SHA-1 to a (preferably sorted) file
when the objects are legitimate, i.e. when it is determined that those
problematic objects should be allowed to enter the server.

We already have support in `git receive-pack` to deal with some legacy
repositories which have non-fatal issues.
Let's make `git fsck` itself useful with such repositories, too, by
allowing users to ignore known issues, or at least demote those issues
to mere warnings.
Example: `git -c fsck.missingEmail=ignore fsck` would hide
problems with missing emails in author, committer and tagger lines.
In the same spirit that `git receive-pack`'s usage of the fsck machinery
differs from `git fsck`'s – some of the non-fatal warnings in `git fsck`
are fatal with `git receive-pack` when receive.fsckObjects = true, for
example – we strictly separate the fsck.<msg-id> from the
receive.fsck.<msg-id> settings.

With uploadpack.allowReachableSHA1InWant configuration option set on the

an object that has not been advertised (likely to have been obtained out
of band or from a submodule pointer). Only objects reachable from the
branch tips, i.e. the union of advertised branches and branches hidden by
transfer.hideRefs, will be processed. Note that there is an associated
cost of having to walk back the history to check the reachability.
This feature can be used when obtaining the content of a certain commit,
for which the sha1 is known, without the need of cloning the whole
repository, especially if a shallow fetch is used. Useful cases are e.g.
repositories containing large files in the history, fetching only the
needed data for a submodule checkout, when sharing a sha1 without telling
which exact branch it belongs to and in Gerrit, if you think in terms of
commits instead of change numbers. (The Gerrit case has already been
solved through allowTipSHA1InWant as every Gerrit change has a ref.)

equivalent to passing --no-ff and --ff-only to git-merge. However, if

Currently, there is only one attempt to acquire any lockfile, and if
the lock is held by another process, the locking attempt fails
immediately.
This is not such a limitation for loose reference files. First, they
don't take long to rewrite. Second, most reference updates have a
known "old" value, so if another process is updating a reference at
the same moment that we are trying to lock it, then probably the
expected "old" value will not longer be valid, and the update will
fail anyway.
But these arguments do not hold for packed-refs:
* The packed-refs file can be large and take significant time to
rewrite.
* Many references are stored in a single packed-refs file, so it could
be that the other process was changing a different reference than
the one that we are interested in.
Therefore, it is much more likely for there to be spurious lock
conflicts in connection to the packed-refs file, resulting in
unnecessary command failures.
So, if the first attempt to lock the packed-refs file fails, continue
retrying for a configurable length of time before giving up. The
default timeout is 1 second.

don't support anything older than 8.4.1 anyway, so we no
longer need to worry about quoting.
Even though this does not change the output at all, there
are a few good reasons to drop the quoting:
1. It makes the source prettier to read.
2. We don't quote consistently, which may be confusing when
reading the source.
3. Asciidoctor does not like the quoting, and renders a
literal backslash.

In "git log --decorate", you would see the commit header like this:
commit ... (HEAD, jc/decorate-leaky-separator-color)
where "commit ... (" is painted in color.diff.commit, "HEAD" in
color.decorate.head, ", " in color.diff.commit, the branch name in
color.decorate.branch and then closing ")" in color.diff.commit.
If you wanted to paint the HEAD and local branch name in the same
color as the body text (perhaps because cyan and green are too faint
on a black-on-white terminal to be readable), you would not want to
have to say
[color "decorate"]
head = black
branch = black
because that you would not be able to reuse same configuration on a
white-on-black terminal. You would naively expect
[color "decorate"]
head = normal
branch = normal
to work, but unfortunately it does not. It paints the string "HEAD"
and the branch name in the same color as the opening parenthesis or
comma between the decoration elements. This is because the code
forgets to reset the color after printing the "prefix" in its own
color.
It theoretically is possible that some people were expecting and
relying on that the attribute set as the "diff.commit" color, which
is used to draw these opening parenthesis and inter-item comma, is
inherited by the drawing of branch names, but it is not how the
coloring works everywhere else.

The various types of values set to the configuration variables
deserve more than a brief footnote mention in the syntax section,

A line can be continued via a backquote-LF and can be chomped at a
comment character. But that is not specific to string-typed values.
It is common to all, just like unquoted leading and trailing
whitespaces are stripped and inter-word spacing are retained.
Move the description around and desribe these structural rules
first, then introduce the double-quote facility as a way to override
them, and finally mention various types of values.
Note that these structural rules only apply to the value part of the
configuration file. E.g.
[aSection] \
name \
= value
does not work, because the rules kick in only after seeing "name =".
Both the original and the updated text are phrased in an awkward way
by singling out the "value" part of the line because of this.

is described as "not case sensitive". Use "case-insensitive" for
both.
Instead of saying "... have to be escaped" without telling what that
escaping achieves, state it in a more positive way, i.e. "... can be

The documentation of 'git submodule update' has several problems:
1) It mentions that value 'none' of submodule.$name.update can be
overridden by --checkout, but other combinations of configuration
values and command line options are not mentioned.
2) The documentation of submodule.$name.update is scattered across three
places, which is confusing.
3) The documentation of submodule.$name.update in gitmodules.txt is
incorrect, because the code always uses the value from .git/config
and never from .gitmodules.
4) Documentation of --force was incomplete, because it is only effective
in case of checkout method of update.
Fix all these problems by documenting submodule.*.update in
git-submodule.txt and make everybody else refer to it.

Extending the js/push-to-deploy topic, the behaviour of "git push"

The old text gave an impression that even in a new repository using
old form might be safer. Only Git from pre 1.7.0 days choke on the
correctly named variable, which is ancient by today's standard.

let's make sure that we do not give room for confused questions such
as "why does core.sparse-checkout not work, when add.ignore-errors

The assume-unchanged bit, and consequently core.ignoreStat, can be
misunderstood. Be assertive about the expectation that file changes should
notified to Git.
Overhaul the general wording thus:
1. direct description of what is ignored given first.
2. example instruction of the user manual action required.
3. use sideways indirection for assume-unchanged and update-index
references.
4. add a 'normally' to give leeway for the change detection.

When receive.denyCurrentBranch is set to updateInstead, a push that
tries to update the branch that is currently checked out is accepted
only when the index and the working tree exactly matches the
currently checked out commit, in which case the index and the
working tree are updated to match the pushed commit. Otherwise the
push is refused.
This hook can be used to customize this "push-to-deploy" logic. The
hook receives the commit with which the tip of the current branch is
going to be updated, and can decide what kind of local changes are
acceptable and how to update the index and the working tree to match
the updated tip of the current branch.
For example, the hook can simply run `git read-tree -u -m HEAD "$1"`
in order to emulate 'git fetch' that is run in the reverse direction
with `git push`, as the two-tree form of `read-tree -u -m` is
essentially the same as `git checkout` that switches branches while
keeping the local changes in the working tree that do not interfere
with the difference between the branches.

The point of disallowing ".git" in the index is that we
would never want to accidentally overwrite files in the
repository directory. But this means we need to respect the
filesystem's idea of when two paths are equal. The prior
commit added a helper to make such a comparison for NTFS
and FAT32; let's use it in verify_path().
We make this check optional for two reasons:
1. It restricts the set of allowable filenames, which is
unnecessary for people who are not on NTFS nor FAT32.
In practice this probably doesn't matter, though, as
the restricted names are rather obscure and almost
certainly would never come up in practice.
2. It has a minor performance penalty for every path we
insert into the index.
This patch ties the check to the core.protectNTFS config
option. Though this is expected to be most useful on Windows,
we allow it to be set everywhere, as NTFS may be mounted on
other platforms. The variable does default to on for Windows,
though.
