Work around zsh segfaulting when loading git-completion.zsh

completion: correct zsh detection when run from git-completion.zsh
The "autodie" module was added in Perl 5.10.1, but our INSTALL
document says "version 5.8 or later is needed".
As discussed in <87efhfvxzu.fsf@evledraar.gmail.com> this script is in
contrib/, so we might not want to apply that policy, however in this
case "autodie" was recently added as a "gratuitous safeguard" in
786ef50a23 ("git-credential-netrc: accept gpg option",
2018-05-12) (see
<CAHqJXRE8OKSKcck1APHAHccLZhox+tZi8nNu2RA74RErX8s3Pg@mail.gmail.com>).
Looking at it more carefully the addition of "autodie" inadvertently
introduced a logic error, since having it is equivalent to this patch:
@@ -245,10 +244,10 @@ sub load_netrc {
if ($gpgmode) {
my @cmd = ($options{'gpg'}, qw(--decrypt), $file);
log_verbose("Using GPG to open $file: [@cmd]");
- open $io, "-|", @cmd;
+ open $io, "-|", @cmd or die "@cmd: $!";
} else {
log_verbose("Opening $file...");
- open $io, '<', $file;
+ open $io, '<', $file or die "$file: $!$!;
}
# nothing to do if the open failed (we log the error later)
As shown in the context the intent of that code is not do die but to
log the error later.
Per my reading of the file this was the only thing autodie was doing
in this file (there was no other code it altered). So let's remove it,
both to fix the logic error and to get rid of the dependency.

v2.18.0-rc0~90^2 (completion: reduce overhead of clearing cached
--options, 2018-04-18) worked around a bug in bash's "set" builtin on
MacOS by using compgen instead. It was careful to avoid breaking zsh
by guarding this workaround with
if [[ -n ${ZSH_VERSION-}} ]]
Alas, this interacts poorly with git-completion.zsh's bash emulation:
ZSH_VERSION='' . "$script"
Correct it by instead using a new GIT_SOURCING_ZSH_COMPLETION shell
variable to detect whether git-completion.bash is being sourced from
git-completion.zsh. This way, the zsh variant is used both when run
from zsh directly and when run via git-completion.zsh.
Reproduction recipe:
1. cd git/contrib/completion && cp git-completion.zsh _git
2. Put the following in a new ~/.zshrc file:
autoload -U compinit; compinit
autoload -U bashcompinit; bashcompinit
fpath=(~/src/git/contrib/completion $fpath)
3. Open zsh and "git <TAB>".

The commands that make use of --git-completion-helper feature could
now produce a lot of --no-xxx options that a command can take. This in
many case could nearly double the amount of completable options, using
more screen estate and also harder to search for the wanted option.
This patch attempts to mitigate that by collapsing extra --no-
options, the ones that are added by --git-completion-helper and not in
original struct option arrays. The "--no-..." option will be displayed
in this case to hint about more options, e.g.
> ~/w/git $ git clone --
--bare --origin=
--branch= --progress
--checkout --quiet
--config= --recurse-submodules
--depth= --reference=
--dissociate --reference-if-able=
--filter= --separate-git-dir=
--hardlinks --shallow-exclude=
--ipv4 --shallow-since=
--ipv6 --shallow-submodules
--jobs= --shared
--local --single-branch
--mirror --tags
--no-... --template=
--no-checkout --upload-pack=
--no-hardlinks --verbose
--no-tags
and when you complete it with --no-<tab>, all negative options will be
presented:
> ~/w/git $ git clone --no-
--no-bare --no-quiet
--no-branch --no-recurse-submodules
--no-checkout --no-reference
--no-config --no-reference-if-able
--no-depth --no-separate-git-dir
--no-dissociate --no-shallow-exclude
--no-filter --no-shallow-since
--no-hardlinks --no-shallow-submodules
--no-ipv4 --no-shared
--no-ipv6 --no-single-branch
--no-jobs --no-tags
--no-local --no-template
--no-mirror --no-upload-pack
--no-origin --no-verbose
--no-progress
Corner case: to make sure that people will never accidentally complete
the fake option "--no-..." there must be one real --no- in the first
complete listing even if it's not from the original struct option.
PS. This could could be made simpler with ";&" to fall through from
"--no-*" block and share the code but ";&" is not available on bash-3

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

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

completion script switches to use --list-cmds for selecting

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 correct name in git-send-email.perl is aliasfiletype [1]. There are
actually two instances of this misspelling. The other was found and
fixed in 6068ac8848 (completion: add missing configuration variables -

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.
