When a file has no trailing new line at the end diff records this by

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.

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

Since commit 8cbd431082 ("git-add--interactive: replace hunk

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.

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

Use a filter when comparing diffs to fix the value of non-zero hashes
in diff index lines so we're not hard coding sha1 hash values in the

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).

On top of that, commits that add or remove files double the number of

--compact-summary embeds most of --summary back in --stat in the

- 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)

Add means to disable '-x' tracing for individual test scripts by

test script before sourcing 'test-lib.sh'. However, since '-x'

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').

Test helper functions like test_must_fail may produce
messages to stderr when they see a problem. When the tests
are run with "--verbose", this ends up on the test script's
stderr, and the user can read it.
But there's a problem. Some tests record stderr as part of
the test, like:
test_must_fail git foo 2>output &&
test_i18ngrep expected.message output
In this case the error text goes into "output". This makes
the --verbose output less useful (it also means we might
accidentally match it in the second, though in practice we
tend to produce these messages only on error, so we'd abort
the test when the first command fails).
Let's instead send this user-facing output directly to
descriptor 4, which always points to the original stderr (or
/dev/null in non-verbose mode). And it's already forbidden
to redirect descriptor 4, since we use it for BASH_XTRACEFD,
as explained in 9be795fbce (t5615: avoid re-using descriptor
4, 2017-12-08).

`pager.config` when we are listing or "get"ing config.
We have several getters and some are guaranteed to give at most one line
of output. Paging all getters including those could be convenient from a
documentation point-of-view. The downside would be that a misconfigured
or not so modern pager might wait for user interaction before
terminating. Let's instead respect the config for precisely those
getters which may produce more than one line of output.
`--get-urlmatch` may or may not produce multiple lines of output,
depending on the exact usage. Let's not try to recognize the two modes,
but instead make `--get-urlmatch` always respect the config. Analyzing
the detailed usage might be trivial enough here, but could establish a
precedent that we will never be able to enforce throughout the codebase
and that will just open a can of worms.

Use `test_expect_failure` to document that we currently respect the

the pager interferes with the editor and makes the end result completely

The next commit will teach simple config-setting and `--get` to ignore

The transport-helper protocol c-style quotes the value of
any options passed to the helper via the "option <key> <value>"
directive. However, remote-curl doesn't actually unquote the
push-option values, meaning that we will send the quoted
version to the other side (whereas git-over-ssh would send
the raw value).
The pack-protocol.txt documentation defines the push-options
as a series of VCHARs, which excludes most characters that
would need quoting. But:
1. You can still see the bug with a valid push-option that
starts with a double-quote (since that triggers
quoting).
2. We do currently handle any non-NUL characters correctly
in git-over-ssh. So even though the spec does not say
that we need to handle most quoted characters, it's
nice if our behavior is consistent between protocols.
There are two new tests: the "direct" one shows that this
already works in the non-http case, and the http one covers
this bugfix.

Long time ago at fab47d05 ("merge: force edit and no-ff mode when
merging a tag object", 2011-11-07), "git merge" was made to always
create a merge commit when merging a tag, even when the side branch
being merged is a descendant of the current branch.
This default is good for merges made by upstream maintainers to
integrate work signed by downstream contributors, but will leave
pointless no-ff merges when downstream contributors pull a newer
release tag to make their long-running topic branches catch up with
the upstream. When there is no local work left on the topic, such a
merge should simply fast-forward to the commit pointed at by the
release tag.
Update the default (again) for "git merge" that merges a tag object
to (1) --no-ff (i.e. create a merge commit even when side branch
fast forwards) if the tag being merged is not at its expected place
in refs/tags/ hierarchy and (2) --ff (i.e. allow fast-forward update
when able) otherwise.

Although "git worktree add" learned to run the 'post-checkout' hook in
ade546be47 (worktree: invoke post-checkout hook, 2017-12-07), it
neglected to change to the directory of the newly-created worktree
before running the hook. Instead, the hook runs within the directory
from which the "git worktree add" command itself was invoked, which
effectively neuters the hook since it knows nothing about the new
worktree directory.
Further, ade546be47 failed to sanitize the environment before running
the hook, which means that user-assigned values of GIT_DIR and
GIT_WORK_TREE could mislead the hook about the location of the new
worktree. In the case of "git worktree add" being run from a bare
repository, the GIT_DIR="." assigned by Git itself leaks into the hook's
environment and breaks Git commands; this is so even when the working
directory is correctly changed to the new worktree before the hook runs
since ".", relative to the new worktree directory, does not point at the
bare repository.
Fix these problems by (1) changing to the new worktree's directory
before running the hook, and (2) sanitizing the environment of GIT_DIR
and GIT_WORK_TREE so hooks can't be confused by misleading values.
Enhance the t2025 'post-checkout' tests to verify that the hook is
indeed run within the correct directory and that Git commands invoked by
the hook compute Git-dir and top-level worktree locations correctly.
While at it, also add two new tests: (1) verify that the hook is run
within the correct directory even when the new worktree is created from
a sibling worktree (as opposed to the main worktree); (2) verify that
the hook is provided with correct context when the new worktree is
created from a bare repository (test provided by Lars Schneider).
Implementation Notes:
Rather than sanitizing the environment of GIT_DIR and GIT_WORK_TREE, an
alternative would be to set them explicitly, as is already done for
other Git commands run internally by "git worktree add". This patch opts
instead to sanitize the environment in order to clearly document that
the worktree is fully functional by the time the hook is run, thus does
not require special environmental overrides.
The hook is run manually, rather than via run_hook_le(), since it needs
to change the working directory to that of the worktree, and
run_hook_le() does not provide such functionality. As this is a one-off
case, adding 'run_hook' overloads which allow the directory to be set
does not seem warranted at this time.

This fixes a (probably harmless) parsing problem in
sq_dequote_step(), in which we parse some bogus input
incorrectly rather than complaining that it's bogus.
Our shell-dequoting function is very strict: it can unquote
everything generated by sq_quote(), but not arbitrary
strings. In particular, it only allows characters outside of
the single-quoted string if they are immediately backslashed
and then the single-quoted string is resumed. So:
'foo'\''bar'
is OK. But these are not:
'foo'\'bar
'foo'\'
'foo'\'\''bar'
even though they are all valid shell. The parser has a funny
corner case here. When we see a backslashed character, we
keep incrementing the "src" pointer as we parse it. For a
single sq_dequote() call, that's OK; our next step is to
bail with an error, and we don't care where "src" points.
But if we're parsing multiple strings with sq_dequote_to_argv(),
then our next step is to see if the string is followed by
whitespace. Because we erroneously incremented the "src"
pointer, we don't barf on the bogus backslash that we
skipped. Instead, we may find whitespace that immediately
follows it, and continue as if all is well (skipping the
backslashed character completely!).
In practice, this shouldn't be a big deal. The input is
bogus, and our sq_quote() would never generate this bogus
input. In all but one callers, we are parsing input created
by an earlier call to sq_quote(). That final case is "git
shell", which parses shell-quoting generated by the client.
And in that case we use the singular sq_quote(), which has
always behaved correctly.
One might also wonder if you could provoke a read past the
end of the string. But the answer is no; we still parse
character by character, and would never advance past a NUL.
This patch implements the minimal fix, along with
documenting the restriction (which confused at least me
while reading the code). We should possibly consider
being more liberal in accepting valid shell-quoted words. I
suspect the code may actually be simpler, and it would be
more friendly to anybody generating or editing input by
hand. But I wanted to fix just the immediate bug in this
patch.
We don't have a direct way to unit-test the sq_dequote()
functions, but we can do this by feeding input to
GIT_CONFIG_PARAMETERS (which is not normally a user-facing
interface, but serves here as it expects to see sq_quote()
input from "git -c"). I've included both a bogus example,
and a related "good" one to confirm that we still parse it
correctly.

This function takes two ptr/len pairs, which implies that
they can be arbitrary buffers. But internally, it assumes
that each "ptr" is NUL-terminated at "len" (because we
memcpy an extra byte to pick up the NUL terminator).
In practice this works because each caller only ever passes
strlen(ptr) as the length. But let's drop the "len"
parameters to make our expectations clear.
Note that we can get rid of the "l1" and "l2" variables from
cmd_main() as a further cleanup, since they are now mostly
used to check whether the p1 and p2 arguments are present
(technically the length parameters conflated NULL with the
empty string, which we no longer do, but I think that is
actually an improvement).

In general, using a bare snprintf can truncate the resulting

When we allocate the test_entry flex-struct, we have to add
up all of the elements that go into the flex array. If these
were to overflow a size_t, this would allocate a too-small
buffer, which we would then overflow in our memcpy steps.
Since this is just a test-helper, it probably doesn't matter
in practice, but we should model the correct technique by
using the st_add() macros.
Unfortunately, we cannot use the FLEX_ALLOC() macros here,
because we are stuffing two different buffers into a single
flex array.
While we're here, let's also swap out "malloc" for our
error-checking "xmalloc", and use the preferred
"sizeof(*var)" instead of "sizeof(type)".

These two array allocations have several minor flaws:
- they use bare malloc, rather than our error-checking
xmalloc
- they do a bare multiplication to determine the total
size (which in theory can overflow, though in this case
the sizes are all constants)
- they use sizeof(type), but the type in the second one
doesn't match the actual array (though it's "int" versus
"unsigned int", which are guaranteed by C99 to have the
same size)
None of these are likely to be problems in practice, and
this is just a test helper. But since people often look at
test helpers as reference code, we should do our best to
model the recommended techniques.
Switching to ALLOC_ARRAY fixes all three.

"git worktree remove" basically consists of two things
- delete $GIT_WORK_TREE
- delete $GIT_DIR (which is $SUPER_GIT_DIR/worktrees/something)
If $GIT_WORK_TREE is already gone for some reason, we should be able
to finish the job by deleting $GIT_DIR.
Two notes:
- $GIT_WORK_TREE _can_ be missing if the worktree is locked. In that
case we must not delete $GIT_DIR because the real $GIT_WORK_TREE may
be in a usb stick somewhere. This is already handled because we
check for lock first.
- validate_worktree() is still called because it may do more checks in
future (and it already does something else, like checking main
worktree, but that's irrelevant in this case)

This command allows to delete a worktree. Like 'move' you cannot
remove the main worktree, or one with submodules inside [1].
For deleting $GIT_WORK_TREE, Untracked files or any staged entries are
considered precious and therefore prevent removal by default. Ignored
files are not precious.
When it comes to deleting $GIT_DIR, there's no "clean" check because
there should not be any valuable data in there, except:
- HEAD reflog. There is nothing we can do about this until somebody
steps up and implements the ref graveyard.
- Detached HEAD. Technically it can still be recovered. Although it
may be nice to warn about orphan commits like 'git checkout' does.
[1] We do 'git status' with --ignore-submodules=all for safety
anyway. But this needs a closer look by submodule people before we
can allow deletion. For example, if a submodule is totally clean,
but its repo not absorbed to the main .git dir, then deleting
worktree also deletes the valuable .submodule repo too.

There are two options to move the main worktree, but both have
complications, so it's not implemented yet. Anyway the options are:
- convert the main worktree to a linked one and move it away, leave
the git repository where it is. The repo essentially becomes bare
after this move.
- move the repository with the main worktree. The tricky part is make

type), and otherwise auto-create a "struct object" of the
requested type.
A missing object would hit that latter case: we create a
bogus blob struct, walk all of history looking for it, and
then exit successfully having produced no output.
One reason nobody may have noticed this is that some related
cases do still work OK:
1. If we ask for a tree by sha1, then the call to
lookup_commit_referecne_gently() would have parsed it,
and we would have its true type in the in-memory object
hash.
2. If we ask for a name that doesn't exist but isn't a
40-hex sha1, then get_oid() would complain before we
even look at the objects at all.
We can fix this by replacing the lookup_blob() call with a
check of the true type via sha1_object_info(). This is not
quite as efficient as we could possibly make this check. We
know in most cases that the object was already parsed in the
earlier commit lookup, so we could call lookup_object(),
which does auto-create, and check the resulting struct's
type (or NULL). However it's not worth the fragility nor
code complexity to save a single object lookup.
The new tests cover this case, as well as that of a
tree-by-sha1 (which does work as described above, but was
not explicitly tested).

Attempting to grep the output of test_i18ngrep will not work under a
poison build, since the output is (almost) guaranteed not to have the
string you are looking for. In this case, we have a test_i18ngrep call
which attempts to filter the contents of a file, which was itself the
result of a call to test_i18ngrep. In this case, we can achieve the
same effect with a single call to test_i18ngrep (without creating the
intermediate file), since the second regular expression can be used
without change to filter the original input.
Also, replace a call to test_i18ncmp with test_cmp, since the content
being compared is not subject to i18n anyway.
