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

The discussion in [1] pointed out that '.' is a faulty suggestion as
there is a corner case where it fails:

> Did you forget to 'git add'?
> $ >file && git add file
> $ rungit v2.6.6 submodule deinit .
> $ echo $?
> 0
So instead of a pathspec add the '--all' option to deinit all submodules
and add a test to check for the corner case of an empty repository.
The code only needs to learn about the '--all' option and doesn't
require further changes as `git submodule--helper list "$@"` will list
all submodules when "$@" is empty.

OPT_COUNTUP() merely increments the counter upon --option, and resets it
to 0 upon --no-option, which means that there is no "unspecified" value
with which a client can initialize the counter to determine whether or
not --[no]-option was seen at all.
Make OPT_COUNTUP() treat any negative number as an "unspecified" value
to address this shortcoming. In particular, if a client initializes the
counter to -1, then if it is still -1 after parse_options(), then
neither --option nor --no-option was seen; if it is 0, then --no-option
was seen last, and if it is 1 or greater, than --option was seen last.
This change does not affect the behavior of existing clients because
they all use the initial value of 0 (or more).
Note that builtin/clean.c initializes the variable used with
OPT__FORCE (which uses OPT_COUNTUP()) to a negative value, but it is set
to either 0 or 1 by reading the configuration before the code calls
parse_options(), i.e. as far as parse_options() is concerned, the
initial value of the variable is not negative.
To test this behavior, in test-parse-options.c, "verbose" is set to
"unspecified" while quiet is set to 0 which will test the new behavior
with all sets of values.

Change the hardcoded lookup for .git/hooks/* to optionally lookup in

This is essentially a more intrusive version of the git-init ability to

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

I plan on using this on a centralized Git server where users can create

* We don't make claims about the example hooks which may not be true

ba3c69a9 (commit: teach --gpg-sign option, 2011-10-05) introduced a
"signed commit" by teaching the --[no]-gpg-sign option and the
commit.gpgsign configuration variable to various commands that
create commits.
Teaching these to "git commit" and "git merge", both of which are
end-user facing Porcelain commands, was perfectly fine. Allowing
the plumbing "git commit-tree" to suddenly change the behaviour to
surprise the scripts by paying attention to commit.gpgsign was not.
Among the in-tree scripts, filter-branch, quiltimport, rebase and
stash are the commands that run "commit-tree". If any of these
wants to allow users to always sign every single commit, they should
offer their own configuration (e.g. "filterBranch.gpgsign") with an
option to disable signing (e.g. "git filter-branch --no-gpgsign").
Ignoring commit.gpgsign option _obviously_ breaks the backward
compatibility, but it is easy to follow the standard pattern in
scripts to honor whatever configuration variable they choose to
follow. E.g.
case $(git config --bool commit.gpgsign) in
true) sign=-S ;;
*) sign= ;;
esac &&
git commit-tree $sign ...whatever other args...
Do so to make sure that "git rebase" keeps paying attention to the
configuration variable, which unfortunately is a documented mistake.

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.

Maintainers or third party testers may want to know the exact base tree
the patch series applies to. Teach git format-patch a '--base' option
to record the base tree info and append it at the end of the first
message (either the cover letter or the first patch in the series).
The base tree info consists of the "base commit", which is a well-known
commit that is part of the stable part of the project history everybody
else works off of, and zero or more "prerequisite patches", which are
well-known patches in flight that is not yet part of the "base commit"
that need to be applied on top of "base commit" in topological order
before the patches can be applied.
The "base commit" is shown as "base-commit: " followed by the 40-hex of
the commit object name. A "prerequisite patch" is shown as
"prerequisite-patch-id: " followed by the 40-hex "patch id", which can
be obtained by passing the patch through the "git patch-id --stable"
command.
Imagine that on top of the public commit P, you applied well-known
patches X, Y and Z from somebody else, and then built your three-patch
series A, B, C, the history would be like:
---P---X---Y---Z---A---B---C
With "git format-patch --base=P -3 C" (or variants thereof, e.g. with
"--cover-letter" of using "Z..C" instead of "-3 C" to specify the
range), the base tree information block is shown at the end of the
first message the command outputs (either the first patch, or the
cover letter), like this:
base-commit: P
prerequisite-patch-id: X
prerequisite-patch-id: Y
prerequisite-patch-id: Z

When creating a shallow clone of a repository with submodules, the depth
argument does not influence the submodules, i.e. the submodules are done
as non-shallow clones. It is unclear what the best default is for the
depth of submodules of a shallow clone, so we need to have the possibility
to do all kinds of combinations:
* shallow super project with shallow submodules
e.g. build bots starting always from scratch. They want to transmit
the least amount of network data as well as using the least amount
of space on their hard drive.
* shallow super project with unshallow submodules
e.g. The superproject is just there to track a collection of repositories
and it is not important to have the relationship between the repositories
intact. However the history of the individual submodules matter.
* unshallow super project with shallow submodules
e.g. The superproject is the actual project and the submodule is a
library which is rarely touched.
The new switch to select submodules to be shallow or unshallow supports
all of these three cases.
It is easy to transition from the first to the second case by just
unshallowing the submodules (`git submodule foreach git fetch
--unshallow`), but it is not possible to transition from the second to the
first case (as we would have already transmitted the non shallow over
the network). That is why we want to make the first case the default in
case of a shallow super project. This leads to the inconvenience in the
second case with the shallow super project and unshallow submodules,
as you need to pass `--no-shallow-submodules`.

In order to produce the smallest possible diff and combine several diff
hunks together, we implement a heuristic from GNU Diff which moves diff
hunks forward as far as possible when we find common context above and
below a diff hunk. This sometimes produces less readable diffs when
writing C, Shell, or other programming languages, ie:
...
/*
+ *
+ *
+ */
+
+/*
...
instead of the more readable equivalent of
...
+/*
+ *
+ *
+ */
+
/*
...
Implement the following heuristic to (optionally) produce the desired
output.
If there are diff chunks which can be shifted around, shift each hunk
such that the last common empty line is below the chunk with the rest
of the context above.
This heuristic appears to resolve the above example and several other
common issues without producing significantly weird results. However, as
with any heuristic it is not really known whether this will always be
more optimal. Thus, it can be disabled via diff.compactionHeuristic.
