When we replaced the old shell script based interactive rebase in
commmit 18633e1a22a6 ("rebase -i: use the rebase--helper builtin",
2017-02-09) we introduced a regression of functionality in that the
GIT_DIR would be sent to the environment of the exec command as-is.
This generally meant that it would be passed as "GIT_DIR=.git", which
causes problems for any exec command that wants to run git commands in
a subdirectory.
This isn't a very large regression, since it is not that likely that the
exec command will run a git command, and even less likely that it will
need to do so in a subdir. This regression was discovered by a build
system which uses git-describe to find the current version of the build
system, and happened to do so from the src/ sub directory of the
project.
Fix this by passing in the absolute path of the git directory into the
child environment.

"git rebase -i" starts using the recently updated "sequencer" code.

Now that the sequencer learned to process a "normal" interactive rebase,
we use it. The original shell script is still used for "non-normal"
interactive rebases, i.e. when --root or --preserve-merges was passed.
Please note that the --root option (via the $squash_onto variable) needs
special handling only for the very first command, hence it is still okay
to use the helper upon continue/skip.
Also please note that the --no-ff setting is volatile, i.e. when the
interactive rebase is interrupted at any stage, there is no record of
it. Therefore, we have to pass it from the shell script to the
rebase--helper.
Note: the test t3404 had to be adjusted because the the error messages
produced by the sequencer comply with our current convention to start with
a lower-case letter.

Full pattern must be quoted. So 'pat"t"ern attr' will give exactly

After the previous changes in this series there are only a handful of
$(__gitdir) command substitutions left in the completion script, but
there is still a bit of room for improvements:
1. The command substitution involves the forking of a subshell,
which has considerable overhead on some platforms.
2. There are a few cases, where this command substitution is
executed more than once during a single completion, which means
multiple subshells and possibly multiple 'git rev-parse'
executions. __gitdir() is invoked twice while completing refs
for e.g. 'git log', 'git rebase', 'gitk', or while completing
remote refs for 'git fetch' or 'git push'.
Both of these points can be addressed by using the
__git_find_repo_path() helper function introduced in the previous
commit:
1. __git_find_repo_path() stores the path to the repository in a
variable instead of printing it, so the command substitution
around the function can be avoided. Or rather: the command
substitution should be avoided to make the new value of the
variable set inside the function visible to the callers.
(Yes, there is now a command substitution inside
__git_find_repo_path() around each 'git rev-parse', but that's
executed only if necessary, and only once per completion, see
point 2. below.)
2. $__git_repo_path, the variable holding the path to the
repository, is declared local in the toplevel completion
functions __git_main() and __gitk_main(). Thus, once set, the
path is visible in all completion functions, including all
subsequent calls to __git_find_repo_path(), meaning that they
wouldn't have to re-discover the path to the repository.
So call __git_find_repo_path() and use $__git_repo_path instead of the
$(__gitdir) command substitution to access paths in the .git
directory. Turn tests checking __gitdir()'s repository discovery into
tests of __git_find_repo_path() such that only the tested function
changes but the expected results don't, ensuring that repo discovery
keeps working as it did before.
As __gitdir() is not used anymore in the completion script, mark it as
deprecated and direct users' attention to __git_find_repo_path() and
$__git_repo_path. Yet keep four __gitdir() tests to ensure that it
handles success and failure of __git_find_repo_path() and that it
still handles its optional remote argument, because users' custom
completion scriptlets might depend on it.

To prepare for caching the path to the repository in the following
commit, extract the repository discovering part of __gitdir() into the
__git_find_repo_path() helper function, which stores the found path in
the $__git_repo_path variable instead of printing it. Make __gitdir()
a wrapper around this new function. Declare $__git_repo_path local in
the toplevel completion functions __git_main() and __gitk_main() to
ensure that it never leaks into the environment and influences
subsequent completions (though this isn't necessary right now, as
__gitdir() is still only executed in subshells, but will matter for
the following commit).
Adjust tests checking __gitdir() or any other completion function
calling __gitdir() to perform those checks in a subshell to prevent
$__git_repo_path from leaking into the test environment. Otherwise
leave the tests unchanged to demonstrate that this change doesn't
alter __gitdir()'s behavior.

'git -C <path>' option(s) on the command line should be taken into
account during completion, because
- like '--git-dir=<path>', it can lead us to a different repository,
- a few git commands executed in the completion script do care about
in which directory they are executed, and
- the command for which we are providing completion might care about
in which directory it will be executed.
However, unlike '--git-dir=<path>', the '-C <path>' option can be
specified multiple times and their effect is cumulative, so we can't
just store a single '<path>' in a variable. Nor can we simply
concatenate a path from '-C <path1> -C <path2> ...', because e.g. (in
an arguably pathological corner case) a relative path might be
followed by an absolute path.
Instead, store all '-C <path>' options word by word in the
$__git_C_args array in the main git completion function, and pass this
array, if present, to 'git rev-parse --absolute-git-dir' when
discovering the repository in __gitdir(), and let it take care of
multiple options, relative paths, absolute paths and everything.
Also pass all '-C <path> options via the $__git_C_args array to those
git executions which require a worktree and for which it matters from
which directory they are executed from. There are only three such
cases:
- 'git diff-index' and 'git ls-files' in __git_ls_files_helper()
used for git-aware filename completion, and
- the 'git ls-tree' used for completing the 'ref:path' notation.
The other git commands executed in the completion script don't need
these '-C <path>' options, because __gitdir() already took those
options into account. It would not hurt them, either, but let's not
induce unnecessary code churn.

The output of 'git rev-parse --git-dir' can be either a relative or an
absolute path, depending on whether the current working directory is
at the top of the worktree or the .git directory or not, or how the
path to the repository is specified via the '--git-dir=<path>' option
or the $GIT_DIR environment variable. And if that output is a
relative path, then it is relative to the directory where any 'git
-C <path>' options might have led us.
This doesn't matter at all for regular scripts, because the git
wrapper automatically takes care of changing directories according to
the '-C <path>' options, and the scripts can then simply follow any
path returned by 'git rev-parse --git-dir', even if it's a relative
path.
Our Bash completion script, however, is unique in that it must run
directly in the user's interactive shell environment. This means that
it's not executed through the git wrapper and would have to take care
of any '-C <path> options on its own, and it can't just change
directories as it pleases. Consequently, adding support for taking
any '-C <path>' options on the command line into account during
completion turned out to be considerably more difficult, error prone
and required more subshells and git processes when it had to cope with
a relative path to the .git directory.
Help this rather special use case and teach 'git rev-parse' a new
'--absolute-git-dir' option which always outputs a canonicalized
absolute path to the .git directory, regardless of whether the path is
discovered automatically or is specified via $GIT_DIR or 'git
--git-dir=<path>'.

The main completion function finds the name of the git command by
iterating through all the words on the command line in search for the
first non-option-looking word. As it is not aware of 'git -C's
mandatory path argument, if the '-C <path>' option is present, 'path'
will be the first such word and it will be mistaken for a git command.
This breaks completion in various ways:
- If 'path' happens to match one of the commands supported by the
completion script, then options of that command will be offered.
- If 'path' doesn't match a supported command and doesn't contain any
characters not allowed in Bash identifier names, then the
completion script does basically nothing and Bash in turn falls
back to filename completion for all subsequent words.
- Otherwise, if 'path' does contain such an unallowed character, then
it leads to a more or less ugly error message in the middle of the
command line. The standard '/' directory separator is such a
character, and it happens to trigger one of the uglier errors:
$ git -C some/path <TAB>sh.exe": declare: `_git_some/path': not a valid identifier
error: invalid key: alias.some/path
Fix this by skipping 'git -C's mandatory path argument while iterating
over the words on the command line. Extend the relevant test with
this case and, while at it, with cases that needed similar treatment
in the past ('--git-dir', '-c', '--work-tree' and '--namespace').
Additionally, silence the standard error of the 'declare' builtins
looking for the completion function associated with the git command
and of the 'git config' query for the aliased command. So if git ever
learns a new option with a mandatory argument in the future, then,
though the completion script will again misbehave, at least the
command line will not be utterly disrupted by those error messages.

e832f5c09680 (completion: avoid ls-remote in certain scenarios,
2013-05-28) turned a 'git ls-remote <remote>' query into a 'git
for-each-ref refs/remotes/<remote>/' to improve responsiveness of
remote refs completion by avoiding potential network communication.
However, it inadvertently made impossible to complete short refs from
a remote given as a URL, e.g. 'git fetch git://server.com/repo.git
<TAB>', because there is, of course, no such thing as
'refs/remotes/git://server.com/repo.git'.
Since the previous commit we tell apart configured remotes, i.e. those
that can have a hierarchy under 'refs/remotes/', from others that
don't, including remotes given as URL, so we know when we can't use
the faster 'git for-each-ref'-based approach.
Resurrect the old, pre-e832f5c09680 'git ls-remote'-based code for the
latter case to support listing short refs from remotes given as a URL.
The code is slightly updated from the original to
- take into account the path to the repository given on the command
line (if any), and
- omit 'ORIG_HEAD' from the query, as 'git ls-remote' will never
list it anyway.
When the remote given to __git_refs() doesn't exist, then it will be
handled by this resurrected 'git ls-remote' query. This code path
doesn't list 'HEAD' unconditionally, which has the nice side effect of
fixing two more expected test failures.

If the remote given to __git_refs() happens to match both the name of
a configured remote and the name of a directory in the current working
directory, then that directory is assumed to be a git repository, and
listing refs from that directory will be attempted. This is wrong,
because in such a situation git commands (e.g. 'git fetch|pull|push
<remote>' whom these refs will eventually be passed to) give
precedence to the configured remote. Therefore, __git_refs() should
list refs from the configured remote as well.
Add the helper function __git_is_configured_remote() that checks
whether its argument matches the name of a configured remote. Use
this helper to decide how to handle the remote passed to __git_refs().

In __git_refs() the git commands listing refs, both short and full,
from a given remote repository are run without giving them the path to
the git repository which might have been specified on the command line
via 'git --git-dir=<path>'. This is bad, those git commands should
access the 'refs/remotes/<remote>/' hierarchy or the remote and
credentials configuration in that specified repository.
Use the __gitdir() helper only to find the path to the .git directory
and pass the resulting path to the 'git ls-remote' and 'for-each-ref'
executions that list remote refs. While modifying that 'for-each-ref'
line, remove the superfluous disambiguating doubledash.
Don't use __gitdir() to check that the given remote is on the file
system: basically it performs only a single if statement for us at the
considerable cost of fork()ing a subshell for a command substitution.
We are better off to perform all the necessary checks of the remote in
__git_refs().
Though __git_refs() was the last remaining callsite that passed a
remote to __gitdir(), don't delete __gitdir()'s remote-handling part
yet, just in case some users' custom completion scriptlets depend on
it.

The __gitdir() helper function prints the path to the git repository
to its stdout or stays silent and returns with error when it can't
find a repository or when the repository given via $GIT_DIR doesn't
exist.
This is not the case, however, when the path in $__git_dir, i.e. the
path to the repository specified on the command line via 'git
--git-dir=<path>', doesn't exist: __gitdir() still outputs it as if it
were a real existing repository, making some completion functions
believe that they operate on an existing repository.
Check that the path in $__git_dir exists and return with error without
printing anything to stdout if it doesn't.

Check how __git_refs() lists refs in different scenarios, i.e.
- short and full refs,
- from a local or from a remote repository,
- remote specified via path, name or URL,
- with or without a repository specified on the command line,
- non-existing remote,
- unique remote branches for 'git checkout's tracking DWIMery,
- not in a git repository, and
- interesting combinations of the above.
Seven of these tests expect failure, mostly demonstrating bugs related
to listing refs from a remote repository:
- ignoring the repository specified on the command line (2 tests),
- listing refs from the wrong place when the name of a configured
remote happens to match a directory,
- listing only 'HEAD' but no short refs from a remote given as URL,
- listing 'HEAD' even from non-existing remotes (2 tests), and
- listing 'HEAD' when not in a repository.

Some tests of the __gitdir() helper function use the $TRASH_DIRECTORY
variable in direct path comparisons. In general this should be
avoided, because it might contain symbolic links. There happens to be
no issues with this here, however, because those tests use
$TRASH_DIRECTORY both for specifying the expected result and for
specifying input which in turn is just 'echo'ed verbatim.
Other __gitdir() tests ask for the path of the trash directory by
running $(pwd -P) in each test, sometimes even twice in a single test.
Run $(pwd) only once at the beginning of the test script to store the
path of the trash directory in a variable, and use that variable in
all __gitdir() tests.

The test helper functions test_gitcomp() and test_gitcomp_nl() leak
the $cur variable into the test environment. Since this variable has
a special role in the Bash completion script (it holds the word
currently being completed) it influences the behavior of most
completion functions and thus this leakage could interfere with
subsequent tests. Although there are no such issues in the current
tests, early versions of the new tests that will be added later in
this series suffered because of this.
It's better to play safe and declare $cur local in those test helper
functions. 'local' is bashism, of course, but the tests of the Bash
completion script are run under Bash anyway, and there are already
other variables declared local in this test script.

While preparing commits, three tests added newly created files to the
index using 'git add .', which added not only the files in question
but leftover test cruft from previous tests like the files 'expected'
and 'actual' as well. Luckily, this had no effect on the tests'
correctness.
Add only the files we are actually interested in.

Instead of erroring out and telling the user that they should add a
positive pattern that covers everything else, just _do_ that.
For commands where we honor the current cwd by default (ie grep, ls-files
etc), we make that default positive pathspec be the current working
directory. And for commands that default to the whole project (ie diff,
log, etc), the default positive pathspec is the whole project.

When tags are created with `--create-reflog` or with the option
`core.logAllRefUpdates` set to 'always', a reflog is created for them.
So far, the description of reflog entries for tags was empty, making the
reflog hard to understand. For example:
6e3a7b3 refs/tags/test@{0}:
Now, a reflog message is generated when creating a tag, following the
pattern "tag: tagging <short-sha1> (<description>)". If
GIT_REFLOG_ACTION is set, the message becomes "$GIT_REFLOG_ACTION
(<description>)" instead. If the tag references a commit object, the
description is set to the subject line of the commit, followed by its
commit date. For example:
6e3a7b3 refs/tags/test@{0}: tag: tagging 6e3a7b3398 (Git 2.12-rc0, 2017-02-03)
If the tag points to a tree/blob/tag objects, the following static
strings are taken as description:
- "tree object"
- "blob object"
- "other tag object"

We de-duplicate ".have" refs among themselves, but never
check if they are duplicates of our local refs. It's not
unreasonable that they would be if we are a "--shared" or
"--reference" clone of a similar repository; we'd have all
the same tags.
We can handle this by inserting our local refs into the
oidset, but obviously not suppressing duplicates (since the
refnames are important).
Note that this also switches the order in which we advertise
refs, processing ours first and then any alternates. The
order shouldn't matter (and arguably showing our refs first
makes more sense).

We forgot that "strip" was introduced at 0571979bd6 ("tag: do not
show ambiguous tag names as "tags/foo"", 2016-01-25) as part of Git
2.8 (and 2.7.1) when we started calling this "lstrip" to make it
easier to explain the new "rstrip" operation.
We shouldn't have renamed the existing one; "lstrip" should have
been a new synonym that means the same thing as "strip". Scripts
in the wild are surely using the original form already.

Port branch.c to use ref-filter APIs for printing. This clears out
most of the code used in branch.c for printing and replaces them with
calls made to the ref-filter library.
Introduce build_format() which gets the format required for printing
of refs. Make amendments to print_ref_list() to reflect these changes.
The strings included in build_format() may not be safely quoted for
inclusion (i.e. it might contain '%' which needs to be escaped with an
additional '%'). Introduce quote_literal_for_format() as a helper
function which takes a string and returns a version of the string that
is safely quoted to be used in the for-each-ref format which is built
in build_format().
Change calc_maxwidth() to also account for the length of HEAD ref, by
calling ref-filter:get_head_discription().
Also change the test in t6040 to reflect the changes.
Before this patch, all cross-prefix symrefs weren't shortened. Since
we're using ref-filter APIs, we shorten all symrefs by default. We also
allow the user to change the format if needed with the introduction of
the '--format' option in the next patch.

Currently the 'lstrip=<N>' option only takes a positive value '<N>'
and strips '<N>' slash-separated path components from the left. Modify
the 'lstrip' option to also take a negative number '<N>' which would
strip from the left as necessary and _leave_ behind only 'N'
slash-separated path components from the right-most end.
For e.g. %(refname:lstrip=-1) would make 'foo/goo/abc' into 'abc'.

Currently when we use the 'lstrip=<N>' option, if 'N' is greater than
the number of components available in the refname, we abruptly end
program execution by calling die().
This behavior is undesired since a single refname with few components
could end program execution. To avoid this, return an empty string
whenever the value 'N' is greater than the number of components
available, instead of calling die().

Use the recently introduced refname_atom_parser_internal() within
remote_ref_atom_parser(), this provides a common base for all the ref
printing atoms, allowing %(upstream) and %(push) to also use the
':strip' option.
The atoms '%(push)' and '%(upstream)' will retain the ':track' and
':trackshort' atom modifiers to themselves as they have no meaning in
context to the '%(refname)' and '%(symref)' atoms.

The "%(symref)" atom doesn't work when used with the ':short' modifier
because we strictly match only 'symref' for setting the 'need_symref'
indicator. Fix this by comparing with the valid_atom rather than the
used_atom.
Add tests for %(symref) and %(symref:short) while we're here.

Add support for %(upstream:track,nobracket) which will print the
tracking information without the brackets (i.e. "ahead N, behind M").
This is needed when we port branch.c to use ref-filter's printing APIs.
Add test and documentation for the same.

Borrowing from branch.c's implementation print "[gone]" whenever an
unknown upstream ref is encountered instead of just ignoring it.
This makes sure that when branch.c is ported over to using ref-filter
APIs for printing, this feature is not lost.
Make changes to t/t6300-for-each-ref.sh and
Documentation/git-for-each-ref.txt to reflect this change.

Add support for %(objectname:short=<length>) which would print the
abbreviated unique objectname of given length. When no length is
specified, the length is 'DEFAULT_ABBREV'. The minimum length is
'MINIMUM_ABBREV'. The length may be exceeded to ensure that the
provided object name is unique.
Add tests and documentation for the same.

Implement %(if:equals=<string>) wherein the if condition is only
satisfied if the value obtained between the %(if:...) and %(then) atom
is the same as the given '<string>'.
Similarly, implement (if:notequals=<string>) wherein the if condition
is only satisfied if the value obtained between the %(if:...) and
%(then) atom is different from the given '<string>'.
This is done by introducing 'if_atom_parser()' which parses the given
%(if) atom and then stores the data in used_atom which is later passed
on to the used_atom of the %(then) atom, so that it can do the required
comparisons.
Add tests and documentation for the same.

Implement %(if), %(then) and %(else) atoms. Used as
%(if)...%(then)...%(end) or %(if)...%(then)...%(else)...%(end). If the
format string between %(if) and %(then) expands to an empty string, or
to only whitespaces, then the whole %(if)...%(end) expands to the string
following %(then). Otherwise, it expands to the string following
%(else), if any. Nesting of this construct is possible.
This is in preparation for porting over `git branch -l` to use
ref-filter APIs for printing.
Add documentation and tests regarding the same.
