By providing aliases via --list-cmds=, we could simplify command
collection code in the script. We only issue one git command. Before
this patch that is "git config", after it's "git --list-cmds=". In
"git help" completion case we actually reduce one "git" process (for
getting guides) but that call was added in this series so it does not
really count.
A couple of bash functions are removed because they are not needed
anymore. __git_compute_all_commands() and $__git_all_commands stay
because they are still needed for completing pager.* config and
without "alias" group, the result is still cacheable.
There is a slight (good) change in _git_help() with this patch: before
"git help <tab>" shows external commands (as in _not_ part of git) as
well as part of $__git_all_commands. We have finer control over
command listing now and can exclude that because we can't provide a
man page for external commands anyway.

Instead of maintaining a separate list of command classification,
which often could go out of date, let's centralize the information
back in git.
While the function in git-completion.bash implies "list porcelain
commands", that's not exactly what it does. It gets all commands (aka
--list-cmds=main,others) then exclude certain non-porcelain ones. We
could almost recreate this list two lists list-mainporcelain and
others. The non-porcelain-but-included-anyway is added by the third
category list-complete.
Note that the current completion script incorrectly classifies
filter-branch as porcelain and t9902 tests this behavior. We keep it
this way in t9902 because this test does not really care which
particular command is porcelain or plumbing, they're just names.

This is part of the effort to break down and provide commands by
category in machine-readable form. This could be helpful later on when
completion script switches to use --list-cmds for selecting
completable commands. It would be much easier for the user to choose
to complete _all_ commands instead of the default selection by passing
different values to --list-cmds in git-completino.bash.
While at there, replace "git help -a" in git-completion.bash with
--list-cmds since it's better suited for this task.

In __gitcomp_file_direct() we tell Bash that it should handle our
possible completion words as filenames with the following piece of
cleverness:
# use a hack to enable file mode in bash < 4
compopt -o filenames +o nospace 2>/dev/null ||
compgen -f /non-existing-dir/ > /dev/null
Unfortunately, this makes this function always return with error
when it is not invoked in real completion, but e.g. in tests of
't9902-completion.sh':
- First the 'compopt' line errors out
- either because in Bash v3.x there is no such command,
- or because in Bash v4.x it complains about "not currently
executing completion function",
- then 'compgen' just silently returns with error because of the
non-existing directory.
Since __gitcomp_file_direct() is now the last command executed in
__git_complete_index_file(), that function returns with error as well,
which prevents it from being invoked in tests directly as is, and
would require extra steps in test to hide its error code.
So let's make sure that __gitcomp_file_direct() doesn't return with
error, because in the tests coming in the following patch we do want
to exercise __git_complete_index_file() directly,
__gitcomp_file() contains the same construct, and thus it, too, always
returns with error. Update that function accordingly as well.
While at it, also remove the space from between the redirection
operator and the filename in both functions.

Adding external subcommands to Git is as easy as to put an executable
file git-foo into PATH. Packaging such subcommands for a Linux
distribution can be achieved by unpacking the executable into /usr/bin
of the user's system. Adding system-wide completion scripts for new
subcommands, however, can be a bit tricky.
Since bash-completion started to use dynamical loading of completion
scripts since v1.90 (preview of v2.0), it is no longer sufficient to
drop a completion script of a subcommand into the standard completions
path, /usr/share/bash-completion/completions, since this script will not
be loaded if called as a git subcommand.
For example, look at https://bugs.gentoo.org/544722. To give a short
summary: The popular git-flow subcommand provides a completion script,
which gets installed as /usr/share/bash-completion/completions/git-flow.
If you now type into a Bash shell:
git flow <TAB>
You will not get any completions, because bash-completion only loads
completions for git and git has no idea that git-flow is defined in
another file. You have to load this script manually or trigger the
dynamic loader with:
git-flow <TAB> # Please notice the dash instead of whitespace
This will not complete anything either, because it only defines a Bash
function, without generating completions. But now the correct completion
script has been loaded and the first command can use the completions.
So, the goal is now to teach the git completion script to consider the
possibility of external completion scripts for subcommands, but of
course without breaking current workflows.
I think the easiest method is to use a function that was defined by
bash-completion v1.90, namely _completion_loader. It will take care of
loading the correct script if present. Afterwards, the git completion
script behaves as usual.
_completion_loader was introduced in commit 20c05b43 of bash-completion
(https://github.com/scop/bash-completion.git) back in 2011, so it should
be available in even older LTS distributions. This function searches for
external completion scripts not only in the default path
/usr/share/bash-completion/completions, but also in the user's home
directory via $XDG_DATA_HOME and in a user specified directory via
$BASH_COMPLETION_USER_DIR.
The only "drawback" (if it even can be called as such) is, that if
_completion_loader does not find a completion script, it automatically
registers a minimal function for basic path completion. In practice,
however, this will not matter, because in this case the given command is
a git command in its dashed form, e.g. 'git-diff-index', and those have
been deprecated for a long time.
This way we can leverage bash-completion's dynamic loading for git
subcommands and make it easier for developers to distribute custom
completion scripts.

The semantic patch 'contrib/coccinelle/commit.cocci' added in
2e27bd7731 (treewide: replace maybe_tree with accessor methods,
2018-04-06) is supposed to "ensure that all references to the
'maybe_tree' member of struct commit are either mutations or accesses
through get_commit_tree()". So get_commit_tree() clearly must be able
to directly access the 'maybe_tree' member, and 'commit.cocci' has a
bit of a roundabout workaround to ensure that get_commit_tree()'s
direct access in its return statement is not transformed: after all
references to 'maybe_tree' have been transformed to a call to
get_commit_tree(), including the reference in get_commit_tree()
itself, the last rule transforms back a 'return get_commit_tree()'
statement, back then found only in get_commit_tree() itself, to a
direct access.
Unfortunately, already the very next commit shows that this workaround
is insufficient: 7b8a21dba1 (commit-graph: lazy-load trees for
commits, 2018-04-06) extends get_commit_tree() with a condition
directly accessing the 'maybe_tree' member, and Coccinelle with
'commit.cocci' promptly detects it and suggests a transformation to
avoid it. This transformation is clearly wrong, because calling
get_commit_tree() to access 'maybe_tree' _in_ get_commit_tree() would
obviously lead to recursion. Furthermore, the same commit added
another, more specialized getter function get_commit_tree_in_graph(),
whose legitimate direct access to 'maybe_tree' triggers a similar
wrong transformation suggestion.
Exclude both of these getter functions from the general rule in
'commit.cocci' that matches their direct accesses to 'maybe_tree'.
Also exclude load_tree_for_commit(), which, as static helper funcion
of get_commit_tree_in_graph(), has legitimate direct access to
'maybe_tree' as well.
The last rule transforming back 'return get_commit_tree()' statements
to direct accesses thus became unnecessary, remove it.

Once upon a time, this here developer thought: wouldn't it be nice if,
say, Git for Windows' patches on top of core Git could be represented as
a thicket of branches, and be rebased on top of core Git in order to
maintain a cherry-pick'able set of patch series?
The original attempt to answer this was: git rebase --preserve-merges.
However, that experiment was never intended as an interactive option,
and it only piggy-backed on git rebase --interactive because that
command's implementation looked already very, very familiar: it was
designed by the same person who designed --preserve-merges: yours truly.
Some time later, some other developer (I am looking at you, Andreas!
;-)) decided that it would be a good idea to allow --preserve-merges to
be combined with --interactive (with caveats!) and the Git maintainer
(well, the interim Git maintainer during Junio's absence, that is)
agreed, and that is when the glamor of the --preserve-merges design
started to fall apart rather quickly and unglamorously.
The reason? In --preserve-merges mode, the parents of a merge commit (or
for that matter, of *any* commit) were not stated explicitly, but were
*implied* by the commit name passed to the `pick` command.
This made it impossible, for example, to reorder commits. Not to mention
to move commits between branches or, deity forbid, to split topic branches
into two.
Alas, these shortcomings also prevented that mode (whose original
purpose was to serve Git for Windows' needs, with the additional hope
that it may be useful to others, too) from serving Git for Windows'
needs.
Five years later, when it became really untenable to have one unwieldy,
big hodge-podge patch series of partly related, partly unrelated patches
in Git for Windows that was rebased onto core Git's tags from time to
time (earning the undeserved wrath of the developer of the ill-fated
git-remote-hg series that first obsoleted Git for Windows' competing
approach, only to be abandoned without maintainer later) was really
untenable, the "Git garden shears" were born [*1*/*2*]: a script,
piggy-backing on top of the interactive rebase, that would first
determine the branch topology of the patches to be rebased, create a
pseudo todo list for further editing, transform the result into a real
todo list (making heavy use of the `exec` command to "implement" the
missing todo list commands) and finally recreate the patch series on
top of the new base commit.
That was in 2013. And it took about three weeks to come up with the
design and implement it as an out-of-tree script. Needless to say, the
implementation needed quite a few years to stabilize, all the while the
design itself proved itself sound.
With this patch, the goodness of the Git garden shears comes to `git
rebase -i` itself. Passing the `--rebase-merges` option will generate
a todo list that can be understood readily, and where it is obvious
how to reorder commits. New branches can be introduced by inserting
`label` commands and calling `merge <label>`. And once this mode will
have become stable and universally accepted, we can deprecate the design
mistake that was `--preserve-merges`.

To get the names of all '$__git_builtin_*' variables caching --options
of builtin commands in order to unset them, 8b0eaa41f2 (completion:
clear cached --options when sourcing the completion script,
2018-03-22) runs a 'set |sed s///' pipeline. This works both in Bash
and in ZSH, but has a higher than necessary overhead with the extra
processes.
In Bash we can do better: run the 'compgen -v __gitcomp_builtin_'
builtin command, which lists the same variables, but without a
pipeline and 'sed' it can do so with lower overhead.
ZSH will still continue to run that pipeline.
This change also happens to work around an issue in the default Bash
version shipped in macOS (3.2.57), reported by users of the Powerline
shell prompt, which was triggered by the same commit 8b0eaa41f2 as
well. Powerline uses several Unicode Private Use Area code points to
represent some of its pretty text UI elements (arrows and what not),
and these are stored in the $PS1 variable. Apparently the 'set'
builtin of said Bash version on macOS has issues with these code
points, and produces garbled output where Powerline's special symbols
should be in the $PS1 variable. This, in turn, triggers the following
error message in the downstream 'sed' process:
sed: RE error: illegal byte sequence
Other Bash versions, notably 4.4.19 on macOS via homebrew (i.e. a
newer version on the same platform) and 3.2.25 on CentOS (i.e. a
slightly earlier version, though on a different platform) are not
affected. ZSH in macOS (the versions shipped by default or installed
via homebrew) or on other platforms isn't affected either.
With this patch neither the 'set' builtin is invoked to print garbage,
nor 'sed' to choke on it.

During git-aware path completion, when a lot of path components have
to be listed, a significant amount of time is spent in
__gitcomp_file(), or more accurately in the shell loop of
__gitcompappend(), iterating over all the path components filtering
path components matching the current word to be completed, adding
prefix path components, and placing the resulting matching paths into
the COMPREPLY array.
Now, a previous patch in this series made 'git ls-files' and 'git
diff-index' list only paths matching the current word to be completed,
so an additional filtering in __gitcomp_file() is not necessary
anymore. Adding the prefix path components could be done much more
efficiently in __git_index_files()'s 'awk' script while stripping
trailing path components and removing duplicates and quoting. And
then the resulting paths won't require any more filtering or
processing before being handed over to Bash, so we could fill the
COMPREPLY array directly.
Unfortunately, we can't simply use the __gitcomp_direct() helper
function to do that, because __gitcomp_file() does one additional
thing: it tells Bash that we are doing filename completion, so the
shell will kindly do four important things for us:
1. Append a trailing space to all filenames.
2. Append a trailing '/' to all directory names.
3. Escape any meta, globbing, separator, etc. characters.
4. List only the current path component when listing possible
completions (i.e. 'dir/subdir/f<TAB>' will list 'file1', 'file2',
etc. instead of the whole 'dir/subdir/file1',
'dir/subdir/file2').
While we could let __git_index_files()'s 'awk' script take care of the
first two points, the third one gets tricky, and we absolutely need
the shell's support for the fourth.
Add the helper function __gitcomp_file_direct(), which, just like
__gitcomp_direct(), fills the COMPREPLY array with prefiltered and
preprocessed paths without any additional processing, without a shell
loop, with just one single compound assignment, and, similar to
__gitcomp_file(), tells Bash and ZSH that we are doing filename
completion. Extend __git_index_files()'s 'awk' script a bit to
prepend any prefix path components to all listed paths. Finally,
modify __git_complete_index_file() to feed __git_index_files()'s
output to ___gitcomp_file_direct() instead of __gitcomp_file().
After this patch there is no shell loop left in the path completion
code path.
This speeds up path completion when there are a lot of paths matching
the current word to be completed. In a pathological repository with
100k files in a single directory, listing all those files:
Before this patch, best of five, using GNU awk on Linux:
$ time cur=dir/ __git_complete_index_file
real 0m0.983s
user 0m1.004s
sys 0m0.033s
After:
real 0m0.313s
user 0m0.341s
sys 0m0.029s
Difference: -68.2%
Speedup: 3.1x
To see the benefits of the whole patch series, the same command with
v2.17.0:
real 0m2.736s
user 0m2.472s
sys 0m0.610s
Difference: -88.6%
Speedup: 8.7x
Note that this patch changes the output of the __git_index_files()
helper function by unconditionally prepending the prefix path
components to every listed path. This would break users' completion
scriptlets that directly run:
__gitcomp_file "$(__git_index_files ...)" "$pfx" "$cur_"
because that would add the prefix path components once more.
However, __git_index_files() is kind of a "helper function of a helper
function", and users' completion scriptlets should have been using
__git_complete_index_file() for git-aware path completion in the first
place, so this is likely doesn't worth worrying about.

If any pathname contains backslash, double quote, tab, newline, or any
control characters, 'git ls-files' and 'git diff-index' will enclose
that pathname in double quotes and escape those special characters
using C-style one-character escape sequences or \nnn octal values.
This prevents those files from being listed during git-aware path
completion, because due to the quoting they will never match the
current word to be completed.
Extend __git_index_files()'s 'awk' script to remove all that quoting
and escaping from unique path components, so even paths containing
(almost all) such special characters can be completed.
Paths containing newline characters are still an issue, though. We
use newlines as separator character when filling the COMPREPLY array,
so a path with one or more newline will end up split to two or more
elements in COMPREPLY, basically breaking completion. There is
nothing we can do about it without a significant performance hit, so
let's just ignore such paths for now. As far as paths with newlines
are concerned, this isn't any different from the previous behavior,
because those paths were always omitted, though in the past they were
omitted because due to the quoting they didn't match the current word
to be completed. Anyway, Bash's own filename completion (Meta-/) can
complete even those paths, if need be.
Note:
- We don't dequote path components right away as they are coming in,
because then we would have to dequote each directory name
repeatedly, as many times as it appears in the input, i.e. as many
times as the number of listed paths it contains. Instead, we
dequote them at the end, as we print unique path components.
- Even when a directory name itself does not contain any special
characters, it will still be quoted if any of its trailing path
components do. If a directory contains paths both with and
without special characters, then the name of that directory will
appear both quoted and unquoted in the output of 'git ls-files'
and 'git diff-index'. Consequently, we will add such a directory
name to the deduplicating associative array twice: once quoted and
once unquoted.
This means that we have to be careful after dequoting a directory
name, and only print it if we haven't seen the same directory name
unquoted.
- It would be wonderful if we could just pass '-z' to those git
commands to output \0-separated unquoted paths, and use \0 as
record separator in the 'awk' script processing their output...
this patch would be so much simpler, almost trivial even.
Unfortunately, however, POSIX and most 'awk' implementations don't
support \0 as record separator (GNU awk does support it).
- This patch makes the earlier change to list paths with
'core.quotePath=false' basically redundant, because this could
decode any \nnn-escaped non-ASCII character just fine, as well.
However, I suspect that 'git ls-files' can deal with those
non-ASCII characters faster than this updated 'awk' script; just
in case someone is burdened with tons of pathnames containing
non-ASCII characters.

During git-aware path completion, after all the trailing path
components have been removed from the output of 'git ls-files' and
'git diff-index' (see previous patch), each directory name is repeated
as many times as the number of listed paths it contains. This can be
a lot of repetitions, especially when invoking path completion close
to the root of a big worktree, which would cause a considerable
overhead downstream of __git_index_files(), in particular in the shell
loop that fills the COMPREPLY array. To reduce this overhead,
__git_index_files() runs the classic '... |sort |uniq' pattern to
remove those repetitions from the function's output.
While removing repeated directory names is effective in reducing the
number of iterations in that shell loop, it still imposes the overhead
of fork()+exec()ing two external processes, and two additional stages
in the pipeline, where potentially relatively large amount of data can
be passed between two subsequent pipeline stages.
Extend __git_index_files()'s 'awk' script to remove repeated path
components by first creating and filling an associative array indexed
by all encountered path components (after the trailing path components
have been removed), and then iterating over this array and printing
the indices, i.e. unique path components. This way we can remove the

Note that this changes order of elements in __git_index_files()'s
output. This is not an issue, because this function was only ever
intended to feed paths into the COMPREPLY array, and Bash will sort
its elements (according to the users locale) anyway.
Note also that using 'awk' to remove repeated path components is also
beneficial for the performance of the next two patches:
- The first will extend this 'awk' script to dequote quoted paths in
the output of 'git ls-files' and 'git diff-index'. With this
patch it will only have to dequote unique path components, not
all.
- The second will, among other things, extend this 'awk' script to
prepend prefix path components from the command line to the
currently completed path component. Consequently, each line in
'awk's output will grow longer. Without this patch that '|sort
|uniq' would have to exchange and process that much more data.

During git-aware path completion we complete one path component at a
time, i.e. 'git add <TAB>' offers only 'dir/' at first, not
'dir/subdir/file' right away, just like Bash's own filename
completion. However, since both 'git ls-files' and 'git diff-index'
dive deep into subdirectories, we have to strip all trailing path
components from the listed paths, keeping only the leading path
component. This stripping is currently done in a shell loop in
__git_index_files(), which can take a significant amount of time when
it has to iterate through a large number of paths.
Replace this shell loop with a little 'awk' script using '/' as input
field separator and printing the first field, which produces the same
output much faster.

During git-aware path completion, e.g. 'git rm dir/fil<TAB>', both
'git ls-files' and 'git diff-index' list all paths in the given 'dir/'
matching certain criteria (cached, modified, untracked, etc.)
appropriate for the given git command, even paths whose names don't
begin with 'fil'. This comes with a considerable performance
penalty when the directory in question contains a lot of paths, but
the current word can be uniquely completed or when only a handful of
those paths match the current word.
Reduce the number of iterations in this codepath from the number of
paths to the number of matching paths by specifying an appropriate
globbing pattern to 'git ls-files' and 'git diff-index' to list only
paths that match the current word to be completed.
Note that both commands treat backslashes as escape characters in
their file arguments, e.g. to preserve the literal meaning of globbing
characters, so we have to double every backslash in the globbing
pattern. This is why one of the path completion tests specifically
checks the completion of a path containing a literal backslash
character (that test still fails, though, because both commands output
such paths enclosed in double quotes and the special characters
escaped; a later patch in this series will deal with those).
This speeds up path completion considerably when there are a lot of
non-matching paths to be filtered out. Uniquely completing a tracked

Our git-aware path completion doesn't work when it has to complete a
word already containing quoted and/or backslash-escaped characters on
the command line. The root cause of the issue is that completion
functions see all words on the command line verbatim, i.e. including
all backslash, single and double quote characters that the shell would
eventually remove when executing the finished command. These
quoting/escaping characters cause different issues depending on which
path component of the word to be completed contains them:
- The quoting/escaping is in the prefix path component(s).
Let's suppose we have a directory called 'New Dir', containing two
untracked files 'file.c' and 'file.o', and we have a gitignore
rule ignoring object files. In this case all of these:
git add New\ Dir/<TAB>
git add "New Dir/<TAB>
git add 'New Dir/<TAB>
should uniquely complete 'file.c' right away, but Bash offers both
'file.c' and 'file.o' instead. The reason for this behavior is
that our completion script uses the prefix directory name like
'git -C "New\ Dir/" ls-files ...", i.e. with the backslash inside
double quotes. Git then tries to enter a directory called
'New\ Dir', which (most likely) fails because such a directory
doesn't exists. As a result our completion script doesn't list
any files, leaves the COMPREPLY array empty, which in turn causes
Bash to fall back to its simple filename completion and lists all
files in that directory, i.e. both 'file.c' and 'file.o'.
- The quoting/escaping is in the path component to be completed.
Let's suppose we have two untracked files 'New File.c' and
'New File.o', and we have a gitignore rule ignoring object files.
In this case all of these:
git add New\ Fi<TAB>
git add "New Fi<TAB>
git add 'New Fi<TAB>
should uniquely complete 'New File.c' right away, but Bash offers
both 'New File.c' and 'New File.o' instead. The reason for this
behavior is that our completion script uses this 'New\ Fi' or
'"New Fi' etc. word to filter matching paths, and of course none
of the potential filenames will match because of the included
backslash or double quote. The end result is the same as above:
the completion script doesn't list any files, Bash falls back to
its filename completion, which then lists the matching object file
as well.
Add the new helper function __git_dequote() [1], which removes (most
of[2]) the quoting and escaping from the word it gets as argument. To
minimize the overhead of calling this function, store its result in
the variable $dequoted_word, supposed to be declared local in the
caller; simply printing the result would require a command
substitution imposing the overhead of fork()ing a subshell. Use this
function in __git_complete_index_file() to dequote the current word,
i.e. the path, to be completed, to avoid the above described
quoting-related issues, thereby fixing two of the failing quoted path
completion tests.
[1] The bash-completion project already has a dequote() function,
which I hoped I could borrow to deal with this, but unfortunately
it doesn't work quite well for this purpose (perhaps that's why
even the bash-completion project only rarely uses it). The main
issue is that their dequote() is implemented as:
eval printf %s "$1" 2> /dev/null
where $1 would contain the word to be completed. While it's a
short and sweet one-liner, the use of 'eval' requires that $1 is a
syntactically valid string, which is not the case when quoting the
path like 'git add "New Dir/<TAB>'. This causes 'eval' to fail,
because it can't find the matching closing double quote, and the
function returns nothing. The result is totally broken behavior,
as if the current word were empty, and the completion script would
then list all files from the current directory. This is why one
of the quoted path completion tests specifically checks the
completion of a path with an opening but without a corresponding
closing double quote character. Furthermore, the 'eval' performs
all kinds of expansions, which may or may not be desired; I think
it's the latter. Finally, using this function would require a
command substitution.
[2] Bash understands the $'string' quoting as well, which "expands to
'string', with backslash-escaped characters replaced as specified
by the ANSI C standard" (quoted from Bash manpage). Since shell
metacharacters, field separators, globbing, etc. can all be easily
entered using standard shell escaping or quoting, this type of
quoting comes in handly when dealing with control characters that
are otherwise difficult both to "type" and to see on the command
line. Because of this difficulty I would assume that people do
avoid pathnames with such control characters anyway, so I didn't
bother implementing it. This function is already way too long as
it is.

Unless the user has 'core.quotePath=false' somewhere in the
configuration, both 'git ls-files' and 'git diff-index' will by
default quote any pathnames that contain bytes with values higher than
0x80, and escape those bytes as '\nnn' octal values. This prevents
completing paths when the current path component to be completed
contains any non-ASCII, most notably UTF-8, characters, because none
of the listed quoted paths will match the current word on the command
line.
Set 'core.quotePath=false' for those 'git ls-files' and 'git
diff-index' invocations, so they won't consider bytes higher than 0x80
as "unusual", and won't quote pathnames containing such characters.
Note that pathnames containing backslash, double quote, or control
characters will still be quoted; a later patch in this series will
deal with those.

Once upon a time 'git -C "" cmd' errored out with "Cannot change to

The git-blame.el mode has been superseded by Emacs's own
vc-annotate (invoked by C-x v g). Users of the git.el mode are now
much better off using either Magit or the Git backend for Emacs's own
VC mode.
These modes were added over 10 years ago when Emacs's own Git support
was much less mature, and there weren't other mature modes in the wild
or shipped with Emacs itself.
These days these modes have few if any users, and users of git aren't
well served by us shipping these (some OS's install them alongside git
by default, which is confusing and leads users astray).
So let's remove these per Alexandre Julliard's message to the
ML[1]. If someone still wants these for some reason they're better
served by hosting these elsewhere (e.g. on ELPA), instead of us
distributing them with git.
However, since downstream packagers such as Debian are packaging this
as git-el it's less disruptive to still carry these files as Elisp
code that'll error out with a message suggesting alternatives, rather
than drop the files entirely[2].
Then rather than receive a cryptic load error when they upgrade
existing users will get an error directing them to the README file, or
to just stop requiring these modes. I think it makes sense to link to
GitHub's hosting of contrib/emacs/README (which'll be updated by the
time users see this) so they don't have to hunt down the packaged
README on their local system.

From the output of ls-files, we remove all but the leftmost path
component and then we eliminate duplicates. We do this in a while loop,
which is a performance bottleneck when the number of iterations is large
(e.g. for 60000 files in linux.git).
$ COMP_WORDS=(git status -- ar) COMP_CWORD=3; time _git
real 0m11.876s
user 0m4.685s
sys 0m6.808s
Replacing the loop with the cut command improves performance
significantly:
$ COMP_WORDS=(git status -- ar) COMP_CWORD=3; time _git

The measurements were done with Msys2 bash, which is used by Git for
Windows.
When filtering the ls-files output we take care not to touch absolute
paths. This is redundant, because ls-files will never output absolute
paths. Remove the unnecessary operations.

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.

This patch fixes a corner case where diff-highlight may
scramble some diffs when combined with --graph.
Commit 7e4ffb4c17 (diff-highlight: add support for --graph
output, 2016-08-29) taught diff-highlight to skip past the
graph characters at the start of each line with this regex:
($COLOR?\|$COLOR?\s+)*
I.e., any series of pipes separated by and followed by
arbitrary whitespace. We need to match more than just a
single space because the commit in question may be indented
to accommodate other parts of the graph drawing. E.g.:
* commit 1234abcd
| ...
| diff --git ...
has only a single space, but for the last commit before a
fork:
| | |
| * | commit 1234abcd
| |/ ...
| | diff --git
the diff lines have more spaces between the pipes and the
start of the diff.
However, when we soak up all of those spaces with the
$GRAPH regex, we may accidentally include the leading space
for a context line. That means we may consider the actual
contents of a context line as part of the diff syntax. In
other words, something like this:
normal context line
-old line
+new line
-this is a context line with a leading dash
would cause us to see that final context line as a removal
line, and we'd end up showing the hunk in the wrong order:
normal context line
-old line
-this is a context line with a leading dash
+new line
Instead, let's a be a little more clever about parsing the
graph. We'll look for the actual "*" line that marks the
start of a commit, and record the indentation we see there.
Then we can skip past that indentation when checking whether
the line is a hunk header, removal, addition, etc.
There is one tricky thing: the indentation in bytes may be
different for various lines of the graph due to coloring.
E.g., the "*" on a commit line is generally shown without
color, but on the actual diff lines, it will be replaced
with a colorized "|" character, adding several bytes. We
work around this here by counting "visible" bytes. This is
unfortunately a bit more expensive, making us about twice as
slow to handle --graph output. But since this is meant to be
used interactively anyway, it's tolerably fast (and the
non-graph case is unaffected).
One alternative would be to search for hunk header lines and
use their indentation (since they'd have the same colors as
the diff lines which follow). But that just opens up
different corner cases. If we see:
| | @@ 1,2 1,3 @@
we cannot know if this is a real diff that has been
indented due to the graph, or if it's a context line that
happens to look like a diff header. We can only be sure of
the indent on the "*" lines, since we know those don't
contain arbitrary data (technically the user could include a
bunch of extra indentation via --format, but that's rare
enough to disregard).

There is not a strong reason to hide this option, and git-merge already
completes this one. Let's allow to complete this for all commands (and
let git-completion.bash do the suppressing if needed).
This makes --rerere-autoupdate completable for am, cherry-pick and
revert. rebase completion is fixed manually because it's a shell
script and does not benefit from --git-completion-helper.

In some projects contributions from groups are only accepted from a
common group email address. But every individual may want to receive
replies to her own personal address. That's what we have 'Reply-To'

line option.
This patch re-uses the $reply_to variable. This could break
out-of-tree patches!

Move the Git::Error and Git::Mail::Address wrappers to the
Git::LoadCPAN::Loader::* namespace, e.g. Git::LoadCPAN::Error. That
module will then either load Error from CPAN (if installed on the OS),
or use Git::FromCPAN::Error.
When I added the Error wrapper in 20d2a30f8f ("Makefile: replace
perl/Makefile.PL with simple make rules", 2017-12-10) I didn't think
about how confusing it would be to have these modules sitting in the
same tree as our normal modules. Let's put these all into
Git::{Load,From}CPAN::* to clearly distinguish them from the rest.
This also makes things a bit less confusing since there was already a
Git::Error namespace ever since 8b9150e3e3 ("Git.pm: Handle failed
commands' output", 2006-06-24).

Desktops and servers tend to have no power sensor, thus on_ac_power returns
255 ("unknown"). Thus, let's take any answer other than 1 ("battery") as
no contraindication to run gc.
If that tool returns "unknown", there's no point in querying other sources
as it already queried them, and is smarter than us (can handle multiple
adapters).

Amazingly, timegm(gmtime(0)) is only 0 before 2020 because perl's
timegm deviates from GNU timegm(3) in how it handles years.
man Time::Local says
Whenever possible, use an absolute four digit year instead.
with a detailed explanation about ambiguity of 2-digit years above that.
Even though this ambiguity is error-prone with >50% of users getting it
wrong, it has been like this for 20+ years, so we just use 4-digit years
everywhere to be on the safe side.
We add some extra logic to cvsimport because it allows 2-digit year
input and interpreting an 18 as 1918 can be avoided easily and safely.

If log.showsignature is true (or --show-signature is passed) while
performing a `subtree add` or `subtree pull`, the command fails.
toptree_for_commit() calls `log` and passes the output to `commit-tree`.
If this output shows the GPG signature data, `commit-tree` throws a
fatal error.
This commit fixes the issue by adding --no-show-signature to `log` calls
in a few places, as well as using the more appropriate `rev-parse`
instead where possible.

The new command `git rebase --show-current-patch` is useful for seeing
the commit related to the current rebase state. Some however may find
the "git show" command behind it too limiting. You may want to
increase context lines, do a diff that ignores whitespaces...
For these advanced use cases, the user can execute any command they
want with the new pseudo ref REBASE_HEAD.
This also helps show where the stopped commit is from, which is hard
to see from the previous patch which implements --show-current-patch.

It is useful to see the full patch while resolving conflicts in a
rebase. The only way to do it now is
less .git/rebase-*/patch
which could turn out to be a lot longer to type if you are in a
linked worktree, or not at top-dir. On top of that, an ordinary user
should not need to peek into .git directory. The new option is
provided to examine the patch.

Pointing the user to $GIT_DIR/rebase-apply may encourage them to mess
around in there, which is not a good thing. With this, the user does
not have to keep the path around somewhere (because after a couple of

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.

This command allows to relocate linked worktrees. Main worktree cannot
(yet) be moved.
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
sure all file descriptors to the repository are closed, or it may
fail on Windows.

Add a --prune-tags option to git-fetch, along with fetch.pruneTags
config option and a -P shorthand (-p is --prune). This allows for
doing any of:
git fetch -p -P
git fetch --prune --prune-tags
git fetch -p -P origin
git fetch --prune --prune-tags origin
Or simply:
git config fetch.prune true &&
git config fetch.pruneTags true &&
git fetch
Instead of the much more verbose:
git fetch --prune origin 'refs/tags/*:refs/tags/*' '+refs/heads/*:refs/remotes/origin/*'
Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches *and* tags deleted
regularly, and have our local references to reflect upstream.
At work we create deployment tags in the repo for each rollout, and
there's *lots* of those, so they're archived within weeks for
performance reasons.
Without this change it's hard to centrally configure such repos in
/etc/gitconfig (on servers that are only used for working with
them). You need to set fetch.prune=true globally, and then for each
repo:
git -C {} config --replace-all remote.origin.fetch "refs/tags/*:refs/tags/*" "^\+*refs/tags/\*:refs/tags/\*$"
Now I can simply set fetch.pruneTags=true in /etc/gitconfig as well,
and users running "git pull" will automatically get the pruning
semantics I want.
Even though "git remote" has corresponding "prune" and "update
--prune" subcommands I'm intentionally not adding a corresponding
prune-tags or "update --prune --prune-tags" mode to that command.
It's advertised (as noted in my recent "git remote doc: correct
dangerous lies about what prune does") as only modifying remote
tracking references, whereas any --prune-tags option is always going
to modify what from the user's perspective is a local copy of the tag,
since there's no such thing as a remote tracking tag.
Ideally add_prune_tags_to_fetch_refspec() would be something that
would use ALLOC_GROW() to grow the 'fetch` member of the 'remote'
struct. Instead I'm realloc-ing remote->fetch and adding the
tag_refspec to the end.
The reason is that parse_{fetch,push}_refspec which allocate the
refspec (ultimately remote->fetch) struct are called many places that
don't have access to a 'remote' struct. It would be hard to change all
their callsites to be amenable to carry around the bookkeeping
variables required for dynamic allocation.
All the other callers of the API first incrementally construct the
string version of the refspec in remote->fetch_refspec via
add_fetch_refspec(), before finally calling parse_fetch_refspec() via
some variation of remote_get().
It's less of a pain to deal with the one special case that needs to
modify already constructed refspecs than to chase down and change all
the other callsites. The API I'm adding is intentionally not
generalized because if we add more of these we'd probably want to
re-visit how this is done.
See my "Re: [BUG] git remote prune removes local tags, depending on
fetch config" (87po6ahx87.fsf@evledraar.gmail.com;
