"pack-objects" can stream a slice of an existing packfile out when
the pack bitmap can tell that the reachable objects are all needed
in the output, without inspecting individual objects.  This

c74271aae7 builtin/log: honor log.decorate
The recent change that introduced autodecorating of refs accidentally
broke the ability of users to set log.decorate = false to override it.
When the git_log_config was traversed a second time with an option other
than log.decorate, the decoration style would be set to the automatic
style, even if the user had already overridden it.  Instead of setting
the option in config parsing, set it in init_log_defaults instead.

Add a test for this case.  The actual additional config option doesn't
matter, but it needs to be something not already set in the
configuration file.

25cd291963 config: complain about --local outside of a git repo
The "--local" option instructs git-config to read or modify
the repository-level config. This doesn't make any sense if
you're not actually in a repository.

Older versions of Git would blindly try to read or write
".git/config". For reading, this would result in a quiet
failure, since there was no config to read (and thus no
matching config value). Writing would generally fail
noisily, since ".git" was unlikely to exist. But since
b1ef400ee (setup_git_env: avoid blind fall-back to ".git",
2016-10-20), we catch this in the call to git_pathdup() and
die with an assertion.

Dying is the right thing to do, but we should catch the
problem early and give a more human-friendly error message.

Note that even without --local, git-config will sometimes
default to using local repository config (e.g., when
writing). These cases are already protected by similar
checks, and covered by a test in t1308.

0d75bfe67b tests: fix tests broken under GETTEXT_POISON=YesPlease
The GETTEXT_POISON=YesPlease compile-time testing option added in my
bb946bba76 ("i18n: add GETTEXT_POISON to simulate unfriendly
translator", 2011-02-22) has been slowly bitrotting as strings have
been marked for translation, and new tests have been added without
running it.

I brought this up on the list ("[BUG] test suite broken with
GETTEXT_POISON=YesPlease", [1]) asking whether this mode was useful at
all anymore. At least one person occasionally uses it, and Lars
Schneider offered to change one of the the Travis builds to run in
this mode, so fix up the failing ones.

My test setup runs most of the tests, with the notable exception of
skipping all the p4 tests, so it's possible that there's still some
lurking regressions I haven't fixed.

c8f7c8b704 t0027: tests are not expensive; remove t0025
The purpose of t0027 is to test all CRLF related conversions at "git
checkout" and "git add".  Running t0027 under Git for Windows takes
3-4 minutes, so the whole script had been marked as "EXPENSIVE".

However, the "Git for Windows" fork overrides this since 2014:
"t0027 is marked expensive, but really, for MinGW we want to run
these tests always."

The test seems not to be expensive on other platforms at all: it
takes less than 14 seconds under Linux, and 63 seconds under Mac Os
X, and this is more or less the same with a SSD or a spinning disk.

So let's drop the "EXPENSIVE" prereq.

While at it, retire t0025; recent "stress" tests show that t0025 is
flaky, reported by Lars Schneider <larsxschneider@gmail.com>, but
all tests in t0025 are covered by t0027 already.

2779f66505 t4051: mark supporting files as requiring LF-only line endings
The test t4051-diff-function-context.sh passes on Linux when
core.autocrlf=true even without marking its support files as LF-only,
but they fail when core.autocrlf=true in Git for Windows' SDK.

The reason is that `grep ... >file.c.new` will keep CR/LF line endings
on Linux (obviously treating CRs as if they were regular characters),
but will be converted to LF-only line endings with MSYS2's grep that is
used in Git for Windows.

As we do not want to validate the way the available `grep` works, let's
just mark the input as LF-only and move on.

614f4f0f35 Fix the remaining tests that failed with core.autocrlf=true
The test suite is mainly developed on Linux and MacOSX, which is the
reason that nobody thought to mark files as LF-only as needed.

The symptom is a test suite that fails left and right when being checked
out using Git for Windows (which defaults to core.autocrlf=true).

Mostly, the problems stem from Git's (LF-only) output being compared to
hard-coded files that are checked out with line endings according to
core.autocrlf (which is of course incorrect). This includes the two test
files in t/diff-lib/, README and COPYING.

This patch can be validated even on Linux by using this cadence:

	git config core.autocrlf true
	rm .git/index && git stash
	make -j15 DEVELOPER=1 test

8a7f8bedf3 t3901: move supporting files into t/t3901/
The current convention is to either generate files on the fly in tests,
or to use supporting files taken from a t/tNNNN/ directory (where NNNN
matches the test's number, or the number of the test from which we
borrow supporting files).

The test t3901-i18n-patch.sh was obviously introduced before that
convention was in full swing, hence its supporting files still lived in
t/t3901-8859-1.txt and t/t3901-utf8.txt, respectively.

cbaf82cc6b receive-pack: verify push options in cert
In commit f6a4e61 ("push: accept push options", 2016-07-14), send-pack
was taught to include push options both within the signed cert (if the
push is a signed push) and outside the signed cert; however,
receive-pack ignores push options within the cert, only handling push
options outside the cert.

Teach receive-pack, in the case that push options are provided for a
signed push, to verify that the push options both within the cert and
outside the cert are consistent.

This sets in stone the requirement that send-pack redundantly send its
push options in 2 places, but I think that this is better than the
alternatives. Sending push options only within the cert is
backwards-incompatible with existing Git servers (which read push
options only from outside the cert), and sending push options only
outside the cert means that the push options are not signed for.

9df4a6074a pack-objects: disable pack reuse for object-selection options
If certain options like --honor-pack-keep, --local, or
--incremental are used with pack-objects, then we need to
feed each potential object to want_object_in_pack() to see
if it should be filtered out. But when the bitmap
reuse_packfile optimization is in effect, we do not call
that function at all, and in fact skip adding the objects to
the to_pack list entirely.  This means we have a bug: for
certain requests we will silently ignore those options and
include objects in that pack that should not be there.

The problem has been present since the inception of the
pack-reuse code in 6b8fda2db (pack-objects: use bitmaps when
packing objects, 2013-12-21), but it was unlikely to come up
in practice.  These options are generally used for on-disk
packing, not transfer packs (which go to stdout), but we've
never allowed pack reuse for non-stdout packs (until
645c432d6, we did not even use bitmaps, which the reuse
optimization relies on; after that, we explicitly turned it
off when not packing to stdout).

We can fix this by just disabling the reuse_packfile
optimization when the options are in use. In theory we could
teach the pack-reuse code to satisfy these checks, but it's
not worth the complexity. The purpose of the optimization is
to keep the amount of per-object work we do to a minimum.
But these options inherently require us to search for other
copies of each object, drowning out any benefit of the
pack-reuse optimization. But note that the optimizations
from 56dfeb626 (pack-objects: compute local/ignore_pack_keep
early, 2016-07-29) happen before pack-reuse, meaning that
specifying "--honor-pack-keep" in a repository with no .keep
files can still follow the fast path.

There are tests in t5310 that check these options with
bitmaps and --stdout, but they didn't catch the bug, and
it's hard to adapt them to do so.

One problem is that they don't use --delta-base-offset;
without that option, we always disable the reuse
optimization entirely. It would be fine to add it in (it
actually makes the test more realistic), but that still
isn't quite enough.

The other problem is that the reuse code is very picky; it
only kicks in when it can reuse most of a pack, starting
from the first byte. So we'd have to start from a fully
repacked and bitmapped state to trigger it. But the tests
for these options use a much more subtle state; they want to
be sure that the want_object_in_pack() code is allowing some
objects but not others. Doing a full repack runs counter to
that.

So this patch adds new tests at the end of the script which
create the fully-packed state and make sure that each option
is not fooled by reusable pack.

5a5221427c diff: recurse into nested submodules for inline diff
When fd47ae6a5b (diff: teach diff to display submodule difference with an
inline diff, 2016-08-31) was introduced, we did not think of recursing
into nested submodules.

When showing the inline diff for submodules, automatically recurse
into nested submodules as well with inline submodule diffs.

218c883783 submodule: properly recurse for read-tree and checkout
We forgot to prepare the submodule env, which is only a problem for
nested submodules. See 2e5d6503bd (ls-files: fix recurse-submodules
with nested submodules, 2017-04-13) for further explanation.

To come up with a proper test for this, we'd need to look at nested
submodules just as in that given commit. It turns out we're lucky
and these tests already exist, but are marked as failing. We need
to pass `--recurse-submodules` to read-tree additionally to make
these tests pass. Passing that flag alone would not make the tests
pass, such that this covers testing for the bug fix of the submodule
env as well.

db4eca1fea clone: handle empty config values in -c
"git clone --config" uses the following incantation to add an item to
a config file, instead of replacing an existing value:

	git_config_set_multivar_gently(key, value, "^$", 0)

As long as no existing value matches the regex ^$, that works as
intended and adds to the config.  When a value is empty, though, it
replaces the existing value.

Noticed while trying to set credential.helper during a clone to use a
specific helper without inheriting from ~/.gitconfig and
/etc/gitconfig.  That is, I ran

	git clone -c credential.helper= \
		-c credential.helper=myhelper \
		https://example.com/repo

intending to produce the configuration

	[credential]
		helper =
		helper = myhelper

Without this patch, the 'helper =' line is not included and the
credential helper from /etc/gitconfig gets used.

0dab2468ee clone: add a --no-tags option to clone without tags
Add a --no-tags option to clone without fetching any tags.

Without this change there's no easy way to clone a repository without
also fetching its tags.

When supplying --single-branch the primary remote branch will be
cloned, but in addition tags will be followed & retrieved. Now
--no-tags can be added --single-branch to clone a repository without
tags, and which only tracks a single upstream branch.

This option works without --single-branch as well, and will do a
normal clone but not fetch any tags.

Many git commands pay some fixed overhead as a function of the number
of references. E.g. creating ~40k tags in linux.git will cause a
command like `git log -1 >/dev/null` to run in over a second instead
of in a matter of milliseconds, in addition numerous other things will
slow down, e.g. "git log <TAB>" with the bash completion will slowly
show ~40k references instead of 1.

The user might want to avoid all of that overhead to simply use a
repository like that to browse the "master" branch, or something like
a CI tool might want to keep that one branch up-to-date without caring
about any other references.

Without this change the only way of accomplishing this was either by
manually tweaking the config in a fresh repository:

    git init git &&
    cat >git/.git/config <<EOF &&
    [remote "origin"]
        url = git@github.com:git/git.git
        tagOpt = --no-tags
        fetch = +refs/heads/master:refs/remotes/origin/master
    [branch "master"]
        remote = origin
        merge = refs/heads/master
    EOF
    cd git &&
    git pull

Which requires hardcoding the "master" name, which may not be the main
--single-branch would have retrieved, or alternatively by setting
tagOpt=--no-tags right after cloning & deleting any existing tags:

    git clone --single-branch git@github.com:git/git.git &&
    cd git &&
    git config remote.origin.tagOpt --no-tags &&
    git tag -l | xargs git tag -d

Which of course was also subtly buggy if --branch was pointed at a
tag, leaving the user in a detached head:

    git clone --single-branch --branch v2.12.0 git@github.com:git/git.git &&
    cd git &&
    git config remote.origin.tagOpt --no-tags &&
    git tag -l | xargs git tag -d

Now all this complexity becomes the much simpler:

    git clone --single-branch --no-tags git@github.com:git/git.git

Or in the case of cloning a single tag "branch":

    git clone --single-branch --branch v2.12.0 --no-tags git@github.com:git/git.git

7f1b225153 t7400: add !CYGWIN prerequisite to 'add with \\ in path'
Commit cf9e55f494 ("submodule: prevent backslash expantion in submodule
names", 07-04-2017) added a test which creates a git repository with
some backslash characters in the name. On windows, where the backslash
character is a directory separator, it is not possible to create a
repository with the name 'sub\with\backslash'. (The NTFS filesystem would
probably allow it, but the win32 api does not). The MinGW and Git for
Windows versions of git actually create a repository called 'backslash'
in the sub-directory 'sub/with'.

On cygwin, however, due to the slightly schizophrenic treatment of the
backslash character by cygwin-git, this test fails at the 'git init'
stage. The git-init command does not recognise the directory separators
in the input path (eg. is_dir_sep('\\') is false), so it does not
attempt to create the leading directories 'sub/with'. (The call to
mkdir('sub\\with\\backslash') actually does recognise the directory
separators, but fails because the 'sub/with' directory doesn't exist).

In order to suppress the test failure (for now), add the !CYGWIN test
prerequisite.
