Nguyễn Thái Ngọc Duy 2b1c01d22e parse-options: option to let --git-completion-helper show negative form
When 7fb6aefd2a (Merge branch 'nd/parseopt-completion' - 2018-03-14)
is merged, the completion for negative form is left out because the
series is alread long and it could be done in a follow up series. This
is it.

--git-completion-helper now provides --no-xxx so that git-completion.bash
can drop the extra custom --no-xxx in the script. It adds a lot more
--no-xxx than what's current provided by the git-completion.bash
script. We'll trim that down later.

Nguyễn Thái Ngọc Duy 3301d36b29 completion: add and use --list-cmds=alias
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.

Nguyễn Thái Ngọc Duy 84a9713106 completion: let git provide the completable command list
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which often could go out of date, let's centralize the information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.

SZEDER Gábor 8b4c2e0b1c completion: don't return with error from __gitcomp_file_direct()
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.

Florian Gamböck 085e2ee0e6 completion: load completion file for external subcommand
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.

SZEDER Gábor 279ffad17d coccinelle: avoid wrong transformation suggestions from commit.cocci
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.

Johannes Schindelin 8f6aed71d2 rebase: introduce the --rebase-merges option
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`.

We define 'git stash -p' as an alias for 'git stash push -p' in the
manpage.  Do the same in the completion script, so all options that
can be given to 'git stash push' are being completed when the user is
using 'git stash -p --<tab>'.  Currently the only additional option
the user will get is '--message', but there may be more in the future.

The 'save' subcommand in git stash has been deprecated in

Stop showing it when the users enters 'git stash <tab>' or 'git stash

or any more characters of the 'save' subcommand.  This is designed to
not encourage users to use 'git stash save', but still leaving the

SZEDER Gábor 94408dc71c completion: reduce overhead of clearing cached --options
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.

SZEDER Gábor 7b00342068 completion: fill COMPREPLY directly when completing paths
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.

SZEDER Gábor 193757f806 completion: improve handling quoted paths in 'git ls-files's output
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.

SZEDER Gábor c1bc0a0e92 completion: remove repeated dirnames with 'awk' during path completion
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
'|sort |uniq' pipeline stages, and their eliminated overhead results
in faster path completion.

Listing all tracked files (12) and directories (23) at the top of the
worktree in linux.git (over 62k files), i.e. what's doing all the hard
work behind 'git rm <TAB>':

  Before this patch, best of five, using GNU awk on Linux:

    real    0m0.069s
    user    0m0.089s
    sys     0m0.026s

  After:

    real    0m0.052s
    user    0m0.072s
    sys     0m0.014s

  Difference: -24.6%

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.

SZEDER Gábor 105c0efff3 completion: use 'awk' to strip trailing path components
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.

Listing all tracked files (12) and directories (23) at the top of the
worktree in linux.git (over 62k files), i.e. what's doing all the hard
work behind 'git rm <TAB>':

  Before this patch, best of five, using GNU awk on Linux:

  After:

    sys     0m0.023s

  Difference: -96.9%
  Speedup:     32.1x

Note that this could be done with 'sed', or even with 'cut', just as
well, but the upcoming patches require 'awk's scriptability.

Note also that this change means one more fork()+exec()ed process
during path completion, adding more overhead especially on Windows,
but a later patch will more than make up for it by eliminating two
other processes in the same function.

SZEDER Gábor a364e984d1 completion: let 'ls-files' and 'diff-index' filter matching paths
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
filename at the top of the worktree in linux.git (over 62k files),
i.e. what's doing all the hard work behind 'git rm Mak<TAB>' to

SZEDER Gábor f12785a3a7 completion: improve handling quoted paths on the command line
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.

SZEDER Gábor 3dfe23ba51 completion: support completing non-ASCII pathnames
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.

Ævar Arnfjörð Bjarmason 6d5ed4836d git{,-blame}.el: remove old bitrotting Emacs code
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.

Clemens Buchacher 78a2d21231 completion: improve ls-files filter performance
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

real    0m1.372s
user    0m0.263s
sys     0m0.167s

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 issue was reported here:

SZEDER Gábor 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.

Jeff King 4551fbba14 diff-highlight: detect --graph by indent
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 will never be any color. Let's do at least one --color
test to make sure that we can handle this case (which we
currently can, but will be an easy thing to mess up when we
touch the graph code in a future patch).

We'll just cover the --graph case, since this is much more
complex than the earlier cases (i.e., if it manages to
highlight, then the non-graph case definitely would).

Jeff King 7ce2f4ca0e diff-highlight: test interleaved parallel lines of history
The graph test in t9400 covers the case of two simultaneous
branches, but all of the commits during this time are on the
right-hand branch. So we test a graph structure like:

  | |
  | * commit ...
  | |

but we never see the reverse, a commit on the left-hand
branch:

  | |
  * | commit ...
  | |

Since this is an easy thing to get wrong when touching the
graph-matching code, let's cover it by adding one more
commit with its timestamp interleaved with the other branch.

Note that we need to pass --date-order to convince Git to
show it this way (since --topo-order tries to keep lines of
history separate).

subject to how long the test script takes to run).

Let's use test_tick to make sure this is stable. Note that
we actually have to rearrange the order of the branches to

previously we might racily have been testing a slightly
different output, though the test is written in such a way

Ævar Arnfjörð Bjarmason 28654678cf perl: move CPAN loader wrappers to another namespace
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

Bernhard M. Wiedemann a40e06ee33 perl: call timegm and timelocal with 4-digit year
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.

Stephen R Guglielmo 8841b5222c subtree: fix add and pull for GPG-signed commits
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.

Nguyễn Thái Ngọc Duy fbd7a23237 rebase: introduce and use pseudo-ref REBASE_HEAD
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.

Nguyễn Thái Ngọc Duy cc73385cf6 worktree remove: new command
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.

Ævar Arnfjörð Bjarmason 97716d217c fetch: add a --prune-tags option and fetch.pruneTags config
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;
https://public-inbox.org/git/87po6ahx87.fsf@evledraar.gmail.com/) for

This is a __gitcomp wrapper that will execute

    git ... --git-completion-helper

to get the list of completable options. The call will be made only
once and cached to avoid performance issues, especially on Windows.

__gitcomp_builtin() allows callers to change its output a bit by adding
some more options, or removing some.

- Current --git-completion-helper for example does not output --no-foo
  form, this has to be added manually by __gitcomp_builtin() callers
  when necessary

- Some options from --git-completion-helper should only be available in
  certain conditions (e.g. --continue and friends). __gitcomp_builtin()
  callers can remove them if the conditions are not met.

There's a rule in strbuf.cocci for converting trivial uses of
strbuf_addf() to strbuf_addstr() in order to simplify the code and
improve performance a bit.  Coccinelle 1.0.0~rc19.deb-3 on Travis CI
lets the "%s" in that rule match format strings like "%d" as well for
some reason, though, leading to invalid proposed patches.

Use the "format" keyword to let Coccinelle parse the format string and
match the conversion specifier with a trivial regular expression
instead.  This works fine with both Coccinelle 1.0.0~rc19.deb-3 and
1.0.4.deb-3+b3 (the current version on Debian testing).

Ævar Arnfjörð Bjarmason 20d2a30f8f Makefile: replace perl/Makefile.PL with simple make rules
Replace the perl/Makefile.PL and the fallback perl/Makefile used under
NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily
inspired by how the i18n infrastructure's build process works[1].

The reason for having the Makefile.PL in the first place is that it
was initially[2] building a perl C binding to interface with libgit,
this functionality, that was removed[3] before Git.pm ever made it to
the master branch.

We've since since started maintaining a fallback perl/Makefile, as
MakeMaker wouldn't work on some platforms[4]. That's just the tip of
the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to
detect whether we need to regenerate the perl/perl.mak, which I fixed
just recently to deal with issues like the perl version changing from
under us[6].

There is absolutely no reason for why this needs to be so complex
anymore. All we're getting out of this elaborate Rube Goldberg machine
was copying perl/* to perl/blib/* as we do a string-replacement on
the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as
pod2man-ing Git.pm & friends.

So replace the whole thing with something that's pretty much a copy of
how we generate po/build/**.mo from po/*.po, just with a small sed(1)
command instead of msgfmt. As that's being done rename the files
from *.pm to *.pmc just to indicate that they're generated (see
"perldoc -f require").

While I'm at it, change the fallback for Error.pm from being something
where we'll ship our own Error.pm if one doesn't exist at build time
to one where we just use a Git::Error wrapper that'll always prefer
the system-wide Error.pm, only falling back to our own copy if it
really doesn't exist at runtime. It's now shipped as
Git::FromCPAN::Error, making it easy to add other modules to
Git::FromCPAN::* in the future if that's needed.

Functional changes:

 * This will not always install into perl's idea of its global
   "installsitelib". This only potentially matters for packagers that
   need to expose Git.pm for non-git use, and as explained in the
   INSTALL file there's a trivial workaround.

 * The scripts themselves will 'use lib' the target directory, but if
   INSTLIBDIR is set it overrides it. It doesn't have to be this way,
   it could be set in addition to INSTLIBDIR, but my reading of [7] is
   that this is the desired behavior.

 * We don't build man pages for all of the perl modules as we used to,
   only Git(3pm). As discussed on-list[8] that we were building
   installed manpages for purely internal APIs like Git::I18N or
   private-Error.pm was always a bug anyway, and all the Git::SVN::*
   ones say they're internal APIs.

   There are apparently external users of Git.pm, but I don't expect
   there to be any of the others.

   As a side-effect of these general changes the perl documentation
   now only installed by install-{doc,man}, not a mere "install" as
   before.

Robert Abel 041fe8fc83 git-prompt: fix reading files with windows line endings
If any of the files read by __git_eread have \r\n line endings, read
will only strip \n, leaving \r. This results in an ugly prompt, where
instead of

    user@pc MINGW64 /path/to/repo (BARE:master)

the last parenthesis is printed over the beginning of the prompt like

    )ser@pc MINGW64 /path/to/repo (BARE:master

This patch fixes the issue by changing the internal field separator
variable IFS to $'\r\n' before using the read builtin command.

Note that ANSI-C Quoting/POSIX Quoting ($'...') is supported by bash
as well as zsh, which are the current targets of git-prompt, cf.
contrib/completion/git-prompt.sh.

Antoine Beaupré da2a180977 remote-mediawiki: support fetching from (Main) namespace
When we specify a list of namespaces to fetch from, by default the MW
API will not fetch from the default namespace, refered to as "(Main)"
in the documentation:

https://www.mediawiki.org/wiki/Manual:Namespace#Built-in_namespaces

I haven't found a way to address that "(Main)" namespace when getting
the namespace ids: indeed, when listing namespaces, there is no
"canonical" field for the main namespace, although there is a "*"
field that is set to "" (empty). So in theory, we could specify the
empty namespace to get the main namespace, but that would make
specifying namespaces harder for the user: we would need to teach
users about the "empty" default namespace. It would also make the code
more complicated: we'd need to parse quotes in the configuration.

So we simply override the query here and allow the user to specify
"(Main)" since that is the publicly documented name.

Antoine Beaupré db3364352d remote-mediawiki: skip virtual namespaces
Virtual namespaces do not correspond to pages in the database and are
automatically generated by MediaWiki. It makes little sense,
therefore, to fetch pages from those namespaces and the MW API doesn't
support listing those pages.

According to the documentation, those virtual namespaces are currently
"Special" (-1) and "Media" (-2) but we treat all negative namespaces
as "virtual" as a future-proofing mechanism.

Antoine Beaupré 09eebbadca remote-mediawiki: show known namespace choices on failure
If we fail to find a requested namespace, we should tell the user
which ones we know about, since those were already fetched. This
allows users to fetch all namespaces by specifying a dummy namespace,
failing, then copying the list of namespaces in the config.

Eventually, we should have a flag that allows fetching all namespaces
automatically.

A new option --ignore-cr-at-eol tells the diff machinery to treat a
carriage-return at the end of a (complete) line as if it does not
exist.

Just like other "--ignore-*" options to ignore various kinds of
whitespace differences, this will help reviewing the real changes
you made without getting distracted by spurious CRLF<->LF conversion
made by your editor program.

xiaoqiang zhao 5453b83bdf send-email: --batch-size to work around some SMTP server limit
Some email servers (e.g. smtp.163.com) limit the number emails to be
sent per session (connection) and this will lead to a faliure when
sending many messages.

Teach send-email to disconnect after sending a number of messages
(configurable via the --batch-size=<num> option), wait for a few
seconds (configurable via the --relogin-delay=<seconds> option) and
reconnect, to work around such a limit.

Also add two configuration variables to give these options the default.

Note:

  We will use this as a band-aid for now, but in the longer term, we
  should look at and react to the SMTP error code from the server;
  Xianqiang reports that 450 and 451 are returned by problematic
  servers.

Jeff King 0c977dbc81 diff-highlight: split code into module
The diff-so-fancy project is also written in perl, and most
of its users pipe diffs through both diff-highlight and
diff-so-fancy. It would be nice if this could be done in a
single script. So let's pull most of diff-highlight's code
into its own module which can be used by diff-so-fancy.

In addition, we'll abstract a few basic items like reading
from stdio so that a script using the module can do more
processing before or after diff-highlight handles the lines.
See the README update for more details.

One small downside is that the diff-highlight script must
now be built using the Makefile. There are ways around this,
but it quickly gets into perl arcana. Let's go with the
simple solution. As a bonus, our Makefile now respects the
PERL_PATH variable if it is set.

Jeff King 2c9a2ae285 docs/config: mention protocol implications of url.insteadOf
If a URL rewrite switches the protocol to something
nonstandard (like "persistent-https" for "https"), the user
may be bitten by the fact that the default protocol
restrictions are different between the two. Let's drop a
note in insteadOf that points the user in the right
direction.

It would be nice if we could make this work out of the box,
but we can't without knowing the security implications of
the user's rewrite. Only the documentation for a particular
remote helper can advise one way or the other. Since we do
include the persistent-https helper in contrib/ (and since
it was the helper in the real-world case that inspired that
patch), let's also drop a note there.

Ævar Arnfjörð Bjarmason 0dab2468ee clone: add a --no-tags option to clone without tags
Add a --no-tags option to clone without fetching any tags.

Without this change there's no easy way to clone a repository without
also fetching its tags.

When supplying --single-branch the primary remote branch will be
cloned, but in addition tags will be followed & retrieved. Now
--no-tags can be added --single-branch to clone a repository without
tags, and which only tracks a single upstream branch.

This option works without --single-branch as well, and will do a
normal clone but not fetch any tags.

Many git commands pay some fixed overhead as a function of the number
of references. E.g. creating ~40k tags in linux.git will cause a
command like `git log -1 >/dev/null` to run in over a second instead
of in a matter of milliseconds, in addition numerous other things will
slow down, e.g. "git log <TAB>" with the bash completion will slowly
show ~40k references instead of 1.

The user might want to avoid all of that overhead to simply use a
repository like that to browse the "master" branch, or something like
a CI tool might want to keep that one branch up-to-date without caring
about any other references.

Without this change the only way of accomplishing this was either by
manually tweaking the config in a fresh repository:

    git init git &&
    cat >git/.git/config <<EOF &&
    [remote "origin"]
        url = git@github.com:git/git.git
        tagOpt = --no-tags
        fetch = +refs/heads/master:refs/remotes/origin/master
    [branch "master"]
        remote = origin
        merge = refs/heads/master
    EOF
    cd git &&
    git pull

Which requires hardcoding the "master" name, which may not be the main
--single-branch would have retrieved, or alternatively by setting
tagOpt=--no-tags right after cloning & deleting any existing tags:

    git clone --single-branch git@github.com:git/git.git &&
    cd git &&
    git config remote.origin.tagOpt --no-tags &&
    git tag -l | xargs git tag -d

Which of course was also subtly buggy if --branch was pointed at a
tag, leaving the user in a detached head:

    git clone --single-branch --branch v2.12.0 git@github.com:git/git.git &&
    cd git &&
    git config remote.origin.tagOpt --no-tags &&
    git tag -l | xargs git tag -d

Now all this complexity becomes the much simpler:

    git clone --single-branch --no-tags git@github.com:git/git.git

Or in the case of cloning a single tag "branch":

    git clone --single-branch --branch v2.12.0 --no-tags git@github.com:git/git.git

Jeff King 60e71bbcea completion: optionally disable checkout DWIM
When we complete branch names for "git checkout", we also
complete remote branch names that could trigger the DWIM
behavior. Depending on your workflow and project, this can
be either convenient or annoying.

For instance, my clone of gitster.git contains 74 local
"jk/*" branches, but origin contains another 147. When I
want to checkout a local branch but can't quite remember the
name, tab completion shows me 251 entries. And worse, for a
topic that has been picked up for pu, the upstream branch
name is likely to be similar to mine, leading to a high
probability that I pick the wrong one and accidentally
create a new branch.

This patch adds a way for the user to tell the completion
code not to include DWIM suggestions for checkout. This can
already be done by typing:

  git checkout --no-guess jk/<TAB>

but that's rather cumbersome. The downside, of course, is
that you no longer get completion support when you _do_ want
to invoke the DWIM behavior. But depending on your workflow,
that may not be a big loss (for instance, in git.git I am
much more likely to want to detach, so I'd type "git
checkout origin/jk/<TAB>" anyway).

Change the completion of "push --delete <remote> <ref>" to complete

Before this cloning git.git and doing "git push --delete origin
p<TAB>" will complete nothing, since a fresh clone of git.git will
have no "pu" branch, whereas origin/p<TAB> will uselessly complete
origin/pu, but fully qualified references aren't accepted by
"--delete".

Now p<TAB> will complete as "pu". The completion of giving --delete
later, e.g. "git push origin --delete p<TAB>" remains unchanged, this
is a bug, but is a general existing limitation of the bash completion,

Ævar Arnfjörð Bjarmason ac3f5a3468 ref-filter: add --no-contains option to tag/branch/for-each-ref
Change the tag, branch & for-each-ref commands to have a --no-contains
option in addition to their longstanding --contains options.

This allows for finding the last-good rollout tag given a known-bad
<commit>. Given a hypothetically bad commit cf5c7253e0, the git
version to revert to can be found with this hacky two-liner:

    (git tag -l 'v[0-9]*'; git tag -l --contains cf5c7253e0 'v[0-9]*') |
        sort | uniq -c | grep -E '^ *1 ' | awk '{print $2}' | tail -n 10

With this new --no-contains option the same can be achieved with:

    git tag -l --no-contains cf5c7253e0 'v[0-9]*' | sort | tail -n 10

As the filtering machinery is shared between the tag, branch &
for-each-ref commands, implement this for those commands too. A
practical use for this with "branch" is e.g. finding branches which
were branched off between v2.8.0 and v2.10.0:

    git branch --contains v2.8.0 --no-contains v2.10.0

The "describe" command also has a --contains option, but its semantics
are unrelated to what tag/branch/for-each-ref use --contains for. A
--no-contains option for "describe" wouldn't make any sense, other
than being exactly equivalent to not supplying --contains at all,
which would be confusing at best.

Add a --without option to "tag" as an alias for --no-contains, for
consistency with --with and --contains.  The --with option is
undocumented, and possibly the only user of it is
Junio (<xmqqefy71iej.fsf@gitster.mtv.corp.google.com>). But it's
trivial to support, so let's do that.

The additions to the the test suite are inverse copies of the
corresponding --contains tests. With this change --no-contains for
tag, branch & for-each-ref is just as well tested as the existing
--contains option.

In addition to those tests, add a test for "tag" which asserts that
--no-contains won't find tree/blob tags, which is slightly
unintuitive, but consistent with how --contains works & is documented.

condition checking the existence of the tag file before invoking this

We could still live with this if there were only a single callsite,
but the next commit will add a few more, so it's worth providing a
cleaner interface.

Add the wrapper function __git_complete_symbol(), which encompasses

COMPREPLY, and accepts '--opt=val'-style options with default values

SZEDER Gábor fef56eb006 completion: fill COMPREPLY directly when completing refs
__gitcomp_nl() iterates over all the possible completion words it gets
as argument

  - filtering matching words,
  - appending a trailing space to each matching word (in all but two
    cases),
  - prepending a prefix to each matching word (when completing words
    after e.g. '--option=<TAB>' or 'master..<TAB>'), and
  - adding each matching word to the COMPREPLY array.

This takes a while when a lot of refs are passed to __gitcomp_nl().

The previous changes in this series ensure that __git_refs() lists
only refs matching the current word to be completed, making a second
filtering in __gitcomp_nl() redundant.

Adding the necessary prefix and suffix could be done in __git_refs()
as well:

  - When refs come from 'git for-each-ref', then that prefix and
    suffix could be added much more efficiently using a 'git
    for-each-ref' format containing said prefix and suffix.  Care
    should be taken, though, because that prefix might contain
    'for-each-ref' format specifiers as part of the left hand side of
    a '..' range or '...' symmetric difference notation or
    fetch/push/etc. refspec, e.g. 'git log "evil-%(refname)..br<TAB>'.
    Doubling every '%' in the prefix will prevent 'git for-each-ref'
    from interpolating any of those contained specifiers.
  - When refs come from 'git ls-remote', then that prefix and suffix
    can be added in the shell loop that has to process 'git
    ls-remote's output anyway.
  - Finally, the prefix and suffix can be added to that handful of
    potentially matching symbolic and pseudo refs right away in the
    shell loop listing them.

And then all what is still left to do is to assign a bunch of
newline-separated words to a shell array, which can be done without a
shell loop iterating over each word, basically making all of
__gitcomp_nl() unnecessary for refs completion.

Add the helper function __gitcomp_direct() to fill the COMPREPLY array
with prefiltered and preprocessed words without any additional
processing, without a shell loop, with just one single compound
assignment.  Modify __git_refs() to accept prefix and suffix
parameters and add them to each and every listed ref as described
above.  Modify __git_complete_refs() to pass the prefix and suffix
parameters to __git_refs() and to feed __git_refs()'s output to
__gitcomp_direct() instead of __gitcomp_nl().

This speeds up refs completion when there are a lot of refs matching
the current word to be completed.  Listing all branches for completion
in a repo with 100k local branches, all packed, best of five:

SZEDER Gábor 400a7553c4 completion: let 'for-each-ref' sort remote branches for 'checkout' DWIMery
When listing unique remote branches for 'git checkout's tracking
DWIMery, __git_refs() runs the classic '... |sort |uniq -u' pattern to
filter out duplicate remote branches.

Let 'git for-each-ref' do the sorting, sparing the overhead of
fork()+exec()ing 'sort' and a stage in the pipeline where potentially
relatively large amount of data can be passed between two subsequent
pipeline stages.

This speeds up refs completion for 'git checkout' a bit when a lot of
remote branches match the current word to be completed.  Listing a
single local and 100k remote branches, all packed, best of five:

  On Linux, before:

    $ time __git_complete_refs --track

    real    0m1.856s
    user    0m1.816s
    sys     0m0.060s

  After:

    real    0m1.550s
    user    0m1.512s
    sys     0m0.060s

  On Windows, before:

    real    0m3.128s
    user    0m2.155s
    sys     0m0.183s

  After:

    real    0m2.781s
    user    0m1.826s
    sys     0m0.136s
