7b0d409eb2 p0004: don't abort if multi-threaded is too slow
If the single-threaded variant beats the multi-threaded one then we may
have a performance bug, but that doesn't justify aborting the test.
Drop that check; we can compare the results for --single and --multi
using the actual performance tests.

48a6ace8f5 p0004: use test_perf
The perf test suite (more specifically: t/perf/aggregate.perl) requires
each test script to write test results into a file, otherwise it aborts
when aggregating.  Add actual performance tests with test_perf to allow
p0004 to be run together with other perf scripts.

Calibrate the value for the parameter --count based on the size of the
test repository, in order to get meaningful results with smaller repos
yet still be able to finish the script against huge ones without having
to wait for hours.

The test library puts helpers into $PATH, so we can simply call them

The suffix $X is also not necessary because .exe files on Windows can be

fdb69d33c4 fetch-pack: always allow fetching of literal SHA1s
fetch-pack, when fetching a literal SHA-1 from a server that is not
configured with uploadpack.allowtipsha1inwant (or similar), always
returns an error message of the form "Server does not allow request for
unadvertised object %s". However, it is sometimes the case that such
object is advertised. This situation would occur, for example, if a user
or a script was provided a SHA-1 instead of a branch or tag name for
fetching, and wanted to invoke "git fetch" or "git fetch-pack" using
that SHA-1.

Teach fetch-pack to also check the SHA-1s of the refs in the received
ref advertisement if a literal SHA-1 was given by the user.

e3f43ce765 usage.c: drop set_error_handle()
The set_error_handle() function was introduced by 3b331e926
(vreportf: report to arbitrary filehandles, 2015-08-11) so
that run-command could send post-fork, pre-exec errors to
the parent's original stderr.

That use went away in 79319b194 (run-command: eliminate
calls to error handling functions in child, 2017-04-19),
which pushes all of the error reporting to the parent.
This leaves no callers of set_error_handle(). As we're not
likely to add any new ones, let's drop it.

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.

d8193743e0 usage.c: add BUG() function
There's a convention in Git's code base to write assertions
as:

  if (...some_bad_thing...)
	die("BUG: the terrible thing happened");

with the idea that users should never see a "BUG:" message
(but if they, it at least gives a clue what happened).  We
use die() here because it's convenient, but there are a few
draw-backs:

  1. Without parsing the messages, it's hard for callers to
     distinguish BUG assertions from regular errors.

     For instance, it would be nice if the test suite could
     check that we don't hit any assertions, but
     test_must_fail will pass BUG deaths as OK.

  2. It would be useful to add more debugging features to
     BUG assertions, like file/line numbers or dumping core.

  3. The die() handler can be replaced, and might not
     actually exit the whole program (e.g., it may just
     pthread_exit()). This is convenient for normal errors,
     but for an assertion failure (which is supposed to
     never happen), we're probably better off taking down
     the whole process as quickly and cleanly as possible.

We could address these by checking in die() whether the
error message starts with "BUG", and behaving appropriately.
But there's little advantage at that point to sharing the
die() code, and only downsides (e.g., we can't change the
BUG() interface independently). Moreover, converting all of
the existing BUG calls reveals that the test suite does
indeed trigger a few of them.

Instead, this patch introduces a new BUG() function, which
prints an error before dying via SIGABRT. This gives us test
suite checking and core dumps.  The function is actually a
macro (when supported) so that we can show the file/line
number.

We can convert die("BUG") invocations to BUG() in further
patches, dealing with any test fallouts individually.

9932242f59 read-tree -m: make error message for merging 0 trees less smart aleck
"git read-tree -m" requires a tree argument to name the tree to be
merged in.  Git uses a cutesy error message to say so and why:

    $ git read-tree -m
    warning: read-tree: emptying the index with no arguments is
    deprecated; use --empty
    fatal: just how do you expect me to merge 0 trees?
    $ git read-tree -m --empty
    fatal: just how do you expect me to merge 0 trees?

When lucky, that could produce an ah-hah moment for the user, but it's
more likely to irritate and distract them.

Instead, tell the user plainly that the tree argument is
required. Also document this requirement in the git-read-tree(1)
manpage where there is room to explain it in a more straightforward way.

6c48686263 usability: don't ask questions if no reply is required
There has been a bug report by a corporate user that stated that
"spelling mistake of stash followed by a yes prints character 'y'
infinite times."

This analysis was false. When the spelling of a command contains
errors, the git program tries to help the user by providing candidates
which are close to the unexisting command. E.g Git prints the
following:

        git: 'stahs' is not a git command. See 'git --help'.
        Did you mean this?

        stash

and then exits.

The problem with this hint is that it is not formally indicated as an
hint and the user is in fact encouraged to reply to the question,
whereas the Git command is already finished.

The user was unlucky enough that it was the command he was looking
for, and replied "yes" on the command line, effectively launching the
`yes` program.

The initial error is that the Git programs, when launched in
command-line mode (without interaction) must not ask questions,
because these questions would normally require a user input as a reply
that they won't handle indeed. That's a source of confusion on UX
level.

To improve the general usability of the Git suite, the following rule
was applied:

if the sentence
 * appears in a non-interactive session
 * is printed last before exit
 * is a question addressing the user ("you")

the sentence is turned into affirmative and proposes the option.

The basic rewording of the question sentences has been extended to
other spots found in the source.

cbca060e10 ls-files: prevent prune_cache from overeagerly pruning submodules
Since (ae8d08242 pathspec: pass directory indicator to
match_pathspec_item()) the path matching logic has been able to cope
with submodules without needing to strip off a trailing slash if a path
refers to a submodule.

ls-files is the only caller of 'parse_pathspec()' which relies on the
behavior of the PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP flag because it
uses the result to construct a common prefix of all provided pathspecs
which is then used to prune the index of all entries which don't have
that prefix.  Since submodules entries in the index don't have a
trailing slash 'prune_cache()' will be overeager and prune a submodule
'sub' if the common prefix is 'sub/'.  To correct this behavior, only
prune entries which don't match up to, but not including, a trailing
slash of the common prefix.

This is in preparation to remove the
PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP flag in a later patch.

The "prove cache" is only used in the "script" step for the
"make test" command. Therefore, we should configure the "prove cache"
in this step.

not need the "before_install" step but wants to run the "script" step to

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.

bdab972153 submodule: add die_in_unpopulated_submodule function
Currently 'git add' is the only command which dies when launched from an
unpopulated submodule (the place-holder directory for a submodule which
hasn't been checked out).  This is triggered implicitly by passing the
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag to 'parse_pathspec()'.

Instead make this desire more explicit by creating a function
'die_in_unpopulated_submodule()' which dies if the provided 'prefix' has
a leading path component which matches a submodule in the the index.

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.

Let's adjust to the current convention.

cedf4e27de completion: mark bash script as LF-only
Without this change, the completion script does not work, as Bash expects
its scripts to have line feeds as end-of-line markers (this is
particularly prominent in quoted multi-line strings, where carriage
returns would slip into the strings as verbatim characters otherwise).

This change is required to let t9902-completion pass when Git's source
code is checked out with `core.autocrlf = true`.

bee286f8f7 git-new-workdir: mark script as LF-only
Bash does not handle scripts with CR/LF line endings correctly, therefore
they *have* to be forced to LF-only line endings.

Funnily enough, this fixes t3000-ls-files-others and
t1021-rerere-in-workdir when git.git was checked out with
core.autocrlf=true, as these test still use git-new-workdir (once `git
worktree` is no longer marked as experimental, both scripts probably
want to be ported to using that command instead).

00ddc9d13c Fix build with core.autocrlf=true
On Windows, the default line endings are denoted by a Carriage Return
byte followed by a Line Feed byte, while Linux and MacOSX use a single
Line Feed byte to denote a line ending.

To help with this situation, Git introduced several mechanisms over the
last decade, most prominently the `core.autocrlf` setting.

Sometimes, however, a single setting is incorrect, e.g. when certain
files in the source code are to be consumed by software that can handle
only LF line endings, while other files can use whatever is appropriate
for the current platform.

To allow for that, Git added the `eol` option to its .gitattributes
handling, expecting every user of Git to mark their source code
appropriately.

Bash assumes that line-endings of scripts are denoted by a single Line
Feed byte. Therefore, shell scripts in Git's source code are one example
where that `eol=lf` option is *required*.

When generating common-cmds.h, the Unix tools we use generally operate on
the assumption that input and output deliminate their lines using LF-only
line endings. Consequently, they would happily copy the CR byte verbatim
into the strings in common-cmds.h, which in turn makes the C preprocessor
barf (that interprets them as MacOS-style line endings). Therefore, we
have to mark the input files as LF-only: command-list.txt and
Documentation/git-*.txt.

Quite a bit belatedly, this patch brings Git's own source code in line
with those expectations by setting those attributes to allow for a
correct build even when core.autocrlf=true.

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

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.
