efd71f8913 t/helper: add an empty test-tool program
This will become an umbrella program that absorbs most [1] t/helper
programs in. By having a single executable binary we reduce disk usage
(libgit.a is replicated by every t/helper program) and shorten link
time a bit.

Running "make --jobs=1; du -sh t/helper" with ccache fully populated,
it takes 27 seconds and 277MB at the beginning of this series, 17
seconds and 42MB at the end.

[1] There are a couple programs that will not become part of
    test-tool: test-line-buffer and test-svn-fe have extra
    dependencies and test-fake-ssh's program name has to be a single
    word for some ssh tests.

Most of our tests start with the opening quote of the test body on the

64af7752bb t1405: sort reflog entries in a hash-independent way
The test enumerates reflog entries in an arbitrary order and then sorts
them.  For SHA-1, this produces results that happen to sort in
alphabetical order, but for other hash algorithms they sort differently.
Ensure we sort the reflog entries in a hash-independent way by sorting
on the ref name instead of the object ID.  Remove an assumption about
the length of a hash by using cut with the delimiter and field options
instead of the character range option.

f78ab355e7 filter-branch: fix errors caused by refs that point at non-committish
"git filter-branch -- --all" prints error messages when processing refs that
point at objects that are not committish. Such refs can be created by
"git replace" with trees or blobs. And also "git tag" with trees or blobs can
create such refs.

Filter these problematic refs out early, before they are seen by the logic to
see which refs have been modified and which have been left intact (which is
where the unwanted error messages come from), and warn that these refs are left
unwritten while doing so.

9f642a7169 completion: add --option completion for most builtin commands
Many builtin commands use parseopt which can expose the option list
via --git-completion-helper but do not have explicit support in
git-completion.bash. This patch detects those commands and uses
__gitcomp_builtin for option completion.

This does not pollute the command name completion though. "git <tab>"
will show you the same set as before. This only kicks in when you type
the correct command name.

8b0eaa41f2 completion: clear cached --options when sourcing the completion script
The established way to update the completion script in an already
running shell is to simply source it again: this brings in any new
--options and features, and clears caching variables.  E.g. it clears
the variables caching the list of (all|porcelain) git commands, so
when they are later lazy-initialized again, then they will list and
cache any newly installed commmands as well.

Unfortunately, since d401f3debc (git-completion.bash: introduce
__gitcomp_builtin, 2018-02-09) and subsequent patches this doesn't
work for a lot of git commands' options.  To eliminate a lot of
hard-to-maintain hard-coded lists of options, those commits changed
the completion script to use a bunch of programmatically created and
lazy-initialized variables to cache the options of those builtin
porcelain commands that use parse-options.  These variables are not
cleared upon sourcing the completion script, therefore they continue
caching the old lists of options, even when some commands recently
learned new options or when deprecated options were removed.

Always 'unset' these variables caching the options of builtin commands
when sourcing the completion script.

Redirect 'unset's stderr to /dev/null, because ZSH's 'unset' complains
if it's invoked without any arguments, i.e. no variables caching
builtin's options are set.  This can happen, if someone were to source
the completion script twice without completing any --options in
between.  Bash stays silent in this case.

Add tests to ensure that these variables are indeed cleared when the
completion script is sourced; not just the variables caching options,
but all other caching variables, i.e. the variables caching commands,
porcelain commands and merge strategies as well.

d319bb18b1 stash push -u: don't create empty stash
When introducing the stash push feature, and thus allowing users to pass
in a pathspec to limit the files that would get stashed in
df6bba0937 ("stash: teach 'push' (and 'create_stash') to honor
pathspec", 2017-02-28), this developer missed one place where the
pathspec should be passed in.

Namely in the call to the 'untracked_files()' function in the
'no_changes()' function.  This resulted in 'git stash push -u --
<non-existant>' creating an empty stash when there are untracked files
in the repository other that don't match the pathspec.

As 'git stash' never creates empty stashes, this behaviour is wrong and
confusing for users.  Instead it should just show a message "No local
changes to save", and not create a stash.

Luckily the 'untracked_files()' function already correctly respects
pathspecs that are passed to it, so the fix is simply to pass the
pathspec along to the function.

833622a945 stash push: avoid printing errors
'git stash push -u -- <pathspec>' prints the following errors if
<pathspec> only matches untracked files:

    fatal: pathspec 'untracked' did not match any files
    error: unrecognized input

This is because we first clean up the untracked files using 'git clean
<pathspec>', and then use a command chain involving 'git add -u
<pathspec>' and 'git apply' to clear the changes to files that are in
the index and were stashed.

As the <pathspec> only includes untracked files that were already
removed by 'git clean', the 'git add' call will barf, and so will 'git
apply', as there are no changes that need to be applied.

Fix this by avoiding the 'git clean' if a pathspec is given, and use the
pipeline that's used for pathspec mode to get rid of the untracked files
as well.

327864aaf7 worktree prune: improve prune logic when worktree is moved
Automatic detection of worktree relocation by a user (via 'mv', for
instance) was removed by 618244e160 (worktree: stop supporting moving
worktrees manually - 2016-01-22). Prior to that,
.git/worktrees/<tag>/gitdir was updated whenever the worktree was
accessed in order to let the pruning logic know that the worktree was
"active" even if it disappeared for a while (due to being located on
removable media, for instance).

"git worktree move" has come so we don't really need this, but since
it's easy to do, perhaps we could keep supporting manual worktree move
a bit longer. Notice that when a worktree is active, the "index" file
should be updated pretty often in common case. The logic is updated to
check for index mtime to see if the worktree is alive.

The old logic of checking gitdir's mtime is dropped because nobody
updates it anyway. The new corner case is, if the index file does not
exist, we immediately remove the stale worktree. But if the "index"
file does not exist, you may have a bigger problem.

a4d78ce26b remote-curl: don't request v2 when pushing
In order to be able to ship protocol v2 with only supporting fetch, we
need clients to not issue a request to use protocol v2 when pushing
(since the client currently doesn't know how to push using protocol v2).
This allows a client to have protocol v2 configured in
`protocol.version` and take advantage of using v2 for fetch and falling
back to using v0 when pushing while v2 for push is being designed.

We could run into issues if we didn't fall back to protocol v2 when
pushing right now.  This is because currently a server will ignore a request to
use v2 when contacting the 'receive-pack' endpoint and fall back to
using v0, but when push v2 is rolled out to servers, the 'receive-pack'
endpoint will start responding using v2.  So we don't want to get into a
state where a client is requesting to push with v2 before they actually
know how to push using v2.

Protocol version 2 improves upon version 1 by eliminating the initial
ref advertisement.  In its place a server will export a list of
capabilities and commands which it supports in a capability
advertisement.  A client can then request that a particular command be
executed by providing a number of capabilities and command specific
parameters.  At the completion of a command, a client can request that
another command be executed or can terminate the connection by sending a
flush packet.

The usage is wrong, but we could obviously handle this better. Note that
commit abe549e179 (shortlog: do not require to run from inside a git
repository, 2008-03-14) explicitly enabled `git shortlog` to run from
outside a repo, since we do not need a repo for parsing data from stdin.

c20bf94abc t9402-git-cvsserver-refs: don't check the stderr of a subshell
Four 'cvs diff' related tests in 't9402-git-cvsserver-refs.sh' fail
when the test script is run with '-x' tracing (and using a shell other
than a Bash version supporting BASH_XTRACEFD).  The reason for those
failures is that the tests check the emptiness of a subshell's stderr,
which includes the trace of commands executed in that subshell as
well, throwing off the emptiness check.

Save the stdout and stderr of the invoked 'cvs' command instead of the
whole subshell, so the latter remains free from tracing output.  (Note
that changing how stdout is saved is only done for the sake of
consistency, it's not necessary for correctness.)

After this change t9402 passes with '-x', even when running with
/bin/sh.

54ce2e9be9 t9400-git-cvsserver-server: don't rely on the output of 'test_cmp'
The test 'cvs update (-p)' redirects and checks 'test_cmp's stdout and
even its stderr.  The commit introducing this test in 6e8937a084
(cvsserver: Add test for update -p, 2008-03-27) doesn't discuss why,
in fact its log message only consists of that subject line.  Anyway,
weird as it is, it kind of made sense due to the way that test was
structured:

After a bit of preparation, this test updates four files via CVS and
checks their contents using 'test_cmp', but it does so in a for loop
iterating over the names of those four files.  Now, the exit status of
a for loop is the exit status of the last command executed in the
loop, meaning that the test can't simply rely on the exit code of
'test_cmp' in the loop's body.  Instead, the test works it around by
relying on the stdout of 'test_cmp' being silent on success and
showing the diff on failure, as it appends the stdout of all four
'test_cmp' invocations to a single file and checks that file's
emptiness after the loop (with 'test -z "$(cat ...)"', no less; there
was no 'test_must_be_empty' back then).  Furthermore, the test
redirects the stderr of those 'test_cmp' invocations to this file,
too: while 'test_cmp' itself doesn't output anything to stderr, the
invoked 'diff' or 'cmp' commands do send their error messages there,
e.g. if they can't open a file because its name was misspelled.

This also makes this test fail when the test script is run with '-x'
tracing (and using a shell other than a Bash version supporting
BASH_XTRACEFD), because 'test_cmp's stderr contains the trace of the
'diff' command executed inside the helper function, throwing off the
subsequent emptiness check.

Stop relying on 'test_cmp's output and instead run 'test_cmp a b ||
return 1' in the for loop in order to make 'test_cmp's error code fail
the test.  Furthermore, add the missing && after the cvs command to
create a && chain in the loop's body.

After this change t9400 passes with '-x', even when running with
/bin/sh.

f88590e675 Merge branch 'jc/allow-ff-merging-kept-tags'
Since Git 1.7.9, "git merge" defaulted to --no-ff (i.e. even when
the side branch being merged is a descendant of the current commit,
create a merge commit instead of fast-forwarding) when merging a
tag object.  This was appropriate default for integrators who pull
signed tags from their downstream contributors, but caused an
unnecessary merges when used by downstream contributors who
habitually "catch up" their topic branches with tagged releases
from the upstream.  Update "git merge" to default to --no-ff only
when merging a tag object that does *not* sit at its usual place in
refs/tags/ hierarchy, and allow fast-forwarding otherwise, to
mitigate the problem.

It's important that the diff-filter only filter the
individual lines, and that there remain a one-to-one mapping
between the input and output lines. Otherwise, things like
hunk-splitting will behave quite unexpectedly (e.g., you
think you are splitting at one point, but it has a different
effect in the text patch we apply).

2b8ea7f3c7 add -p: calculate offset delta for edited patches
Recount the number of preimage and postimage lines in a hunk after it
has been edited so any change in the number of insertions or deletions
can be used to adjust the offsets of subsequent hunks. If an edited
hunk is subsequently split then the offset correction will be lost. It
would be possible to fix this if it is a problem, however the code
here is still an improvement on the status quo for the common case
where an edited hunk is applied without being split.

This is also a necessary step to removing '--recount' and
'--allow-overlap' from the invocation of 'git apply'. Before
'--recount' can be removed the splitting and coalescing counting needs
to be fixed to handle a missing newline at the end of a file. In order
to remove '--allow-overlap' there needs to be i) some way of verifying
the offset data in the edited hunk (probably by correlating the
preimage (or postimage if the patch is going to be applied in reverse)
lines of the edited and unedited versions to see if they are offset or
if any leading/trailing context lines have been removed) and ii) a way of
dealing with edited hunks that change context lines that are shared
with neighbouring hunks.

1dbf0c0ad6 userdiff: add built-in pattern for golang
This adds xfuncname and word_regex patterns for golang, a quite
popular programming language. It also includes test cases for the
xfuncname regex (t4018) and updated documentation.

The xfuncname regex finds functions, structs and interfaces.  Although
the Go language prohibits the opening brace from being on its own
line, the regex does not makes it mandatory, to be able to match
`func` statements like this:

    func foo(bar int,
    	baz int) {
    }

This is covered by the test case t4018/golang-long-func.

The word_regex pattern finds identifiers, integers, floats, complex
numbers and operators, according to the go specification.

Since commit 8cbd431082 ("git-add--interactive: replace hunk
recounting with apply --recount", 2008-7-2) if a hunk is skipped then
we rely on the context lines to apply subsequent hunks in the right
place. While this works most of the time it is possible for hunks to
end up being applied in the wrong place. To fix this adjust the offset
of subsequent hunks to correct for any change in the number of
insertions or deletions due to the skipped hunk. The change in offset
due to edited hunks that have the number of insertions or deletions
changed is ignored here, it will be fixed in the next commit.

23fea4c240 t3701: add failing test for pathological context lines
When a hunk is skipped by add -i the offsets of subsequent hunks are
not adjusted to account for any missing insertions due to the skipped
hunk. Most of the time this does not matter as apply uses the context
lines to apply the subsequent hunks in the correct place, however in
pathological cases the context lines will match at the now incorrect
offset and the hunk will be applied in the wrong place. The offsets of
hunks following an edited hunk that has had the number of insertions
or deletions changed also need to be updated in the same way. Add
failing tests to demonstrate this.

Note that both subshells execute four git commands each, meaning that
checking the emptiness of the whole subshell implicitly ensures that
not only 'git merge-recursive' but none of the other three commands
outputs anything to their stderr.  Note also that if one of those
commands were to output anything on its stderr, then the current
combined check would not tell us which one of those four commands the
unexpected output came from.

Save the stderr of those four commands only instead of the whole

them individually, so they will show us from which command the
unexpected output came from.

51b74b57ae t5536: simplify checking of messages output to stderr
Commit 2071e05ed2 ("t5536: new test of refspec conflicts when
fetching", 2013-10-30), introduced the verify_stderr() function
which was used to verify that certain fatal/warning messages were
issued by a given git command. In addition, verify_stderr() would
filter a specific "fatal: The remote end hung up unexpectedly"
message, which may, or may not, be present (depending on the
relative timing of the git-fetch and git-upload-pack processes).

The verify_stderr() function has seen several modifications, which
has introduced a couple of minor problems. For example, commit
1edbaac3bb ("tests: use test_i18n* functions to suppress false
positives", 2016-06-17) introduced an inappropriate test_i18ngrep
call and commit f096e6e826 ("fetch: improve the error messages
emitted for conflicting refspecs", 2013-10-30) included an
ineffective invocation of sort at the end of a grep pipeline.

Instead of fixing these minor problems in verify_stderr(), we take
the simpler approach of directly searching the error file, using
test_i18ngrep, for the specific message(s) we expect. (The only
minor downside is that we would not notice any new messages).

ddf88fa616 diff: add --compact-summary
Certain information is currently shown with --summary, but when used
in combination with --stat it's a bit hard to read since info of the
same file is in two places (--stat and --summary).

On top of that, commits that add or remove files double the number of
display lines, which could be a lot if you add or remove a lot of
files.

--compact-summary embeds most of --summary back in --stat in the
little space between the file name part and the graph line, e.g. with
commit 0433d533f1:

   Documentation/merge-config.txt         |  4 +
   builtin/merge.c                        |  2 +
   ...-pull-verify-signatures.sh (new +x) | 81 ++++++++++++++
   t/t7612-merge-verify-signatures.sh     | 45 ++++++++
   4 files changed, 132 insertions(+)

It helps both condensing information and saving some text
space. What's new in diffstat is:

- A new 0644 file is shown as (new)
- A new 0755 file is shown as (new +x)
- A new symlink is shown as (new +l)
- A deleted file is shown as (gone)
- A mode change adding executable bit is shown as (mode +x)
- A mode change removing it is shown as (mode -x)

Note that --compact-summary does not contain all the information
--summary provides. Rewrite percentage is not shown but it could be
added later, like R50% or C20%.

febb3a8609 merge-recursive: avoid spurious rename/rename conflict from dir renames
If a file on one side of history was renamed, and merely modified on the
other side, then applying a directory rename to the modified side gives us
a rename/rename(1to2) conflict.  We should only apply directory renames to
pairs representing either adds or renames.

Making this change means that a directory rename testcase that was
previously reported as a rename/delete conflict will now be reported as a
modify/delete conflict.

8f581e3a47 directory rename detection: new testcases showcasing a pair of bugs
Add a testcase showing spurious rename/rename(1to2) conflicts occurring
due to directory rename detection.

Also add a pair of testcases dealing with moving directory hierarchies
around that were suggested by Stefan Beller as "food for thought" during
his review of an earlier patch series, but which actually uncovered a
bug.  Round things out with a test that is a cross between the two
testcases that showed existing bugs in order to make sure we aren't
merely addressing problems in isolation but in general.

e0052f4613 merge-recursive: fix overwriting dirty files involved in renames
This fixes an issue that existed before my directory rename detection
patches that affects both normal renames and renames implied by
directory rename detection.  Additional codepaths that only affect
overwriting of dirty files that are involved in directory rename
detection will be added in a subsequent commit.

11395a3b4b test_must_be_empty: make sure the file exists, not just empty
The helper function test_must_be_empty is meant to make sure the
given file is empty, but its implementation is:

	if test -s "$1"
	then
		... not empty, we detected a failure ...
	fi

Surely, the file having non-zero size is a sign that the condition
"the file must be empty" is violated, but it misses the case where
the file does not even exist.  It is an accident waiting to happen
with a buggy test like this:

	git frotz 2>error-message &&
	test_must_be_empty errro-message

that won't get caught until you deliberately break 'git frotz' and
notice why the test does not fail.

c3a4456243 t1507-rev-parse-upstream: don't check the stderr of a shell function
Three tests in 't1507-rev-parse-upstream.sh' fail when the test script
is run with '-x' tracing (and using a shell other than a Bash version
supporting BASH_XTRACEFD).  The reason for those failures is that the
tests check the stderr of the function 'error_message', which includes
the trace of commands executed in that function as well, throwing off
the comparison with the expected output.

Save stderr of 'git rev-parse' only instead of the whole function, so
it remains free from tracing output.

After this change t1507 passes with '-x', even when running with
/bin/sh.

5fc98e79fc t: add means to disable '-x' tracing for individual test scripts
The previous patch resolved most of the test failures caused by
running our test suite with '-x' tracing and /bin/sh, and the
following patches in this series will resolve almost all of the
remaining failures.  Unfortunately, not yet all.

Add means to disable '-x' tracing for individual test scripts by
setting the $test_untraceable variable to a non-empty value in the
test script before sourcing 'test-lib.sh'.  However, since '-x'
tracing is not an issue with recent Bash versions supporting
BASH_XTRACEFD, i.e. v4.1 and later, don't disable tracing when the
test script is run with such a Bash version even when
$test_untraceable is set.

a5bf824f3b t: prevent '-x' tracing from interfering with test helpers' stderr
Running a test script with '-x' turns on 'set -x' tracing, the output
of which is normally sent to stderr.  This causes a lot of
test failures, because many tests redirect and verify the stderr
of shell functions, most frequently that of 'test_must_fail'.
These issues were worked around somewhat in d88785e424 (test-lib: set
BASH_XTRACEFD automatically, 2016-05-11), so at least we could
reliably run tests with '-x' tracing under a Bash version supporting
BASH_XTRACEFD, i.e. v4.1 and later.

Futhermore, redirecting the stderr of test helper functions like
'test_must_fail' or 'test_expect_code' is the cause of a different
issue as well.  If these functions detect something unexpected, they
will write their error messages intended to the user to thier stderr.
However, if their stderr is redirected in order to save and verify the
stderr of the tested git command invoked in the function, then the
function's error messages will be redirected as well.  Consequently,
those messages won't reach the user, making the test's verbose output
less useful.

This patch makes it safe to redirect and verify the stderr of those
test helper functions which are meant to run the tested command given
as argument, even when running tests with '-x' and /bin/sh.  This is
achieved through a couple of file descriptor redirections:

  - Duplicate stderr of the tested command executed in the test helper
    function from the function's fd 7 (see next point), to ensure that
    the tested command's error messages go to a different fd than the
    '-x' trace of the commands executed in the function or the
    function's error messages.

  - Duplicate the test helper function's fd 7 from the function's
    original stderr, meaning that, after taking a detour through fd 7,
    the error messages of the tested command do end up on the
    function's original stderr.

  - Duplicate stderr of the test helper function from fd 4, i.e. the
    fd connected to the test script's original stderr and the fd used
    for BASH_XTRACEFD.  This ensures that the '-x' trace of the
    commands executed in the function

      - doesn't go to the function's original stderr, so it won't mess
	with callers who want to save and verify the tested command's
	stderr.

      - does go to the same fd independently from the shell running
        the test script, be it /bin/sh, an older Bash without
        BASH_XTRACEFD, or a more recent Bash already supporting
        BASH_XTRACEFD.

    Furthermore, this also makes sure that the function's error
    messages go to this fd 4, meaning that the user will be able to
    see them even if the function's stderr is redirected in the test.

  - Specify the latter two redirections above in the test helper
    function's definition, so they are performed every time the
    function is invoked, without the need to modify the callsites of
    the function.

Perform these redirections in those test helper functions which can be
expected to have their stderr redirected, i.e. in the functions
'test_must_fail', 'test_might_fail', 'test_expect_code', 'test_env',
'nongit', 'test_terminal' and 'perl'.  Note that 'test_might_fail',
'test_env', and 'nongit' are not involved in any test failures when
running tests with '-x' and /bin/sh.

The other test helper functions are left unchanged, because they
either don't run commands specified as their arguments, or redirecting
their stderr wouldn't make sense, or both.

With this change the number of failures when running the test suite
with '-x' tracing and /bin/sh goes down from 340 failed tests in 43
test scripts to 22 failed tests in 6 scripts (or 23 in 7, if the
system (OSX) uses an older Bash version without BASH_XTRACEFD to run
't9903-bash-prompt.sh').
