The "interactive.diffFilter" used by "git add -i" must retain
one-to-one correspondence between its input and output, but it was
not enforced and caused end-user confusion. We now at least make
sure the filtered result has the same number of lines as its input
to detect a broken filter.
* jk/add-i-diff-filter:
add--interactive: detect bogus diffFilter output
t3701: add a test for interactive.diffFilter
"git worktree" learned move and remove subcommands.
* nd/worktree-move:
t2028: fix minor error and issues in newly-added "worktree move" tests
worktree remove: allow it when $GIT_WORK_TREE is already gone
worktree remove: new command
worktree move: refuse to move worktrees with submodules
worktree move: accept destination as directory
worktree move: new command
worktree.c: add update_worktree_location()
worktree.c: add validate_worktree()
"git add -p" has been lazy in coalescing split patches before
passing the result to underlying "git apply", leading to corner
case bugs; the logic to prepare the patch to be applied after hunk
selections has been tightened.
* pw/add-p-recount:
add -p: don't rely on apply's '--recount' option
add -p: fix counting when splitting and coalescing
add -p: calculate offset delta for edited patches
add -p: adjust offsets of subsequent hunks when one is skipped
t3701: add failing test for pathological context lines
t3701: don't hard code sha1 hash values
t3701: use test_write_lines and write_script
t3701: indent here documents

A sample auto-gc hook (in contrib/) to skip auto-gc while on
battery has been updated to almost always allow running auto-gc
unless on_ac_power command is absolutely sure that we are on
battery power (earlier, it skipped unless the command is sure that
we are on ac power).
* ab/pre-auto-gc-battery:
hooks/pre-auto-gc-battery: allow gc to run on non-laptops
Running test scripts under -x option of the shell is often not a
useful way to debug them, because the error messages from the
commands tests try to capture and inspect are contaminated by the
tracing output by the shell. An earlier work done to make it more
pleasant to run tests under -x with recent versions of bash is
extended to cover posix shells that do not support BASH_XTRACEFD.
* sg/test-x:
travis-ci: run tests with '-x' tracing
t/README: add a note about don't saving stderr of compound commands
t1510-repo-setup: mark as untraceable with '-x'
t9903-bash-prompt: don't check the stderr of __git_ps1()

t3030-merge-recursive: don't check the stderr of a subshell
t1507-rev-parse-upstream: don't check the stderr of a shell function
t: add means to disable '-x' tracing for individual test scripts

Some codepaths used to take a lockfile and did not roll it back;
they are automatically rolled back at program exit, so there is no
real "breakage", but it still is a good practice to roll back when
you are done with a lockfile.
* ma/roll-back-lockfiles:
sequencer: do not roll back lockfile unnecessarily
merge: always roll back lock in `checkout_fast_forward()`
merge-recursive: always roll back lock in `merge_recursive_generic()`
sequencer: always roll back lock in `do_recursive_merge()`
sequencer: make lockfiles non-static
"git diff" and friends learned "--compact-summary" that shows the
information usually given with the "--summary" option on the same
line as the diffstat output of the "--stat" option (which saves
vertical space and keeps info on a single path at the same place).
* nd/diff-stat-with-summary:
diff: add --compact-summary
diff.c: refactor pprint_rename() to use strbuf
"git commit" used to run "gc --auto" near the end, which was lost
when the command was reimplemented in C by mistake.
* ab/gc-auto-in-commit:
commit: run git gc --auto just before the post-commit hook
Writing out the index file when the only thing that changed in it
is the untracked cache information is often wasteful, and this has
been optimized out.
* bp/untracked-cache-noflush:
untracked cache: use git_env_bool() not getenv() for customization
dir.c: don't flag the index as dirty for changes to the untracked cache
While finding unique object name abbreviation, the code may
accidentally have read beyond the end of the array of object names
in a pack.
* ds/find-unique-abbrev-optim:

Threaded "git grep" has been optimized to avoid allocation in code
section that is covered under a mutex.
* rv/grep-cleanup:
grep: simplify grep_oid and grep_file
grep: move grep_source_init outside critical section
"git status" can spend a lot of cycles to compute the relation
between the current branch and its upstream, which can now be
disabled with "--no-ahead-behind" option.
* jh/status-no-ahead-behind:
status: support --no-ahead-behind in long format
status: update short status to respect --no-ahead-behind
status: add --[no-]ahead-behind to status and commit for V2 format.
stat_tracking_info: return +1 when branches not equal
Build the executable in 'script' phase in Travis CI integration, to
follow the established practice, rather than during 'before_script'
phase. This allows the CI categorize the failures better ('failed'
is project's fault, 'errored' is build environment's).
* sg/travis-build-during-script-phase:
travis-ci: build Git during the 'script' phase
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.
* jc/allow-ff-merging-kept-tags:
merge: allow fast-forward when merging a tracked tag
"git add -p" used to offer "/" (look for a matching hunk) as a
choice, even there was only one hunk, which has been corrected.
Also the single-key help is now given only for keys that are
enabled (e.g. help for '/' won't be shown when there is only one
hunk).
* pw/add-p-single:
add -p: improve error messages
add -p: only bind search key if there's more than one hunk
add -p: only display help for active keys
The new "--show-current-patch" option gives an end-user facing way
to get the diff being applied when "git rebase" (and "git am")
stops with a conflict.
* nd/rebase-show-current-patch:
rebase: introduce and use pseudo-ref REBASE_HEAD
rebase: add --show-current-patch
am: add --show-current-patch
"git send-email" learned to complain when the batch-size option is
not defined when the relogin-delay option is, since these two are
mutually required.
* xz/send-email-batch-size:
send-email: error out when relogin delay is missing
Clarify how configured fetch refspecs interact with the "--prune"
option of "git fetch", and also add a handy short-hand for getting
rid of stale tags that are locally held.
* ab/fetch-prune:
fetch: make the --prune-tags work with <url>
fetch: add a --prune-tags option and fetch.pruneTags config
fetch tests: add scaffolding for the new fetch.pruneTags
git-fetch & config doc: link to the new PRUNING section
git remote doc: correct dangerous lies about what prune does
git fetch doc: add a new section to explain the ins & outs of pruning
fetch tests: fetch <url> <spec> as well as fetch [<remote>]
fetch tests: expand case/esac for later change
fetch tests: double quote a variable for interpolation
fetch tests: test --prune and refspec interaction
fetch tests: add a tag to be deleted to the pruning tests
fetch tests: re-arrange arguments for future readability
fetch tests: refactor in preparation for testing tag pruning
remote: add a macro for "refs/tags/*:refs/tags/*"
fetch: stop accessing "remote" variable indirectly
fetch: trivially refactor assignment to ref_nr
fetch: don't redundantly NULL something calloc() gave us
"git tag" learned an explicit "--edit" option that allows the
message given via "-m" and "-F" to be further edited.
* nm/tag-edit:
tag: add --edit option
Recently-added "git worktree move" tests include a minor error and a few
small issues. Specifically:
* checking non-existence of wrong file ("source" instead of
"destination")
* unneeded redirect (">empty")
* unused variable ("toplevel")
* restoring a worktree location by means of a separate test somewhat
distant from the test which moved it rather than using
test_when_finished() to restore it in a self-contained fashion
* having git command on the left-hand-side of a pipe ("git foo | grep")

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).
We can't detect all problematic cases, but we can at least
catch the obvious case where we don't even have the correct
number of lines.

This feature was added in 01143847db (add--interactive:
allow custom diff highlighting programs, 2016-02-27) but
never tested. Let's add a basic test.
Note that we only apply the filter when color is enabled,
so we have to use test_terminal. This is an open limitation
explicitly mentioned in the original commit. So take this
commit as testing the status quo, and not making a statement
on whether we'd want to enhance that in the future.

The http-protocol.txt spec fails to mention that a flush packet
comes in the smart server response after sending the "service"
header.
Technically the client code is actually ready to receive an
arbitrary number of headers here, but since we haven't
introduced any other headers in the past decade (and the
client would just throw them away), let's not mention it in
the spec.
This fixes both BNF and the example. While we're fixing the
latter, let's also add the missing flush after the ref list.

When a file has no trailing new line at the end diff records this by
appending "\ No newline at end of file" below the last line of the
file. This line should not be counted in the hunk header. Fix the
splitting and coalescing code to count files without a trailing new line
properly and change one of the tests to test splitting without a
trailing new line.

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
numbers and operators, according to the go specification.
