Junio C Hamano 30b7c4bdca setup: notice more types of implicit bare repositories
Setting the safe.bareRepository configuration variable to explicit
stops git from using a bare repository, unless the repository is
explicitly specified, either by the "--git-dir=<path>" command line
option, or by exporting $GIT_DIR environment variable.  This may be
a reasonable measure to safeguard users from accidentally straying
into a bare repository in unexpected places, but often gets in the
way of users who need valid accesses to the repository.

Earlier, 45bb9162 (setup: allow cwd=.git w/ bareRepository=explicit,
2024-01-20) loosened the rule such that being inside the ".git"
directory of a non-bare repository does not really count as
accessing a "bare" repository.  The reason why such a loosening is
needed is because often hooks and third-party tools run from within
$GIT_DIR while working with a non-bare repository.

More importantly, the reason why this is safe is because a directory
whose contents look like that of a "bare" repository cannot be a
bare repository that came embedded within a checkout of a malicious
project, as long as its directory name is ".git", because ".git" is
not a name allowed for a directory in payload.

There are at least two other cases where tools have to work in a
bare-repository looking directory that is not an embedded bare
repository, and accesses to them are still not allowed by the recent
change.

 - A secondary worktree (whose name is $name) has its $GIT_DIR
   inside "worktrees/$name/" subdirectory of the $GIT_DIR of the
   primary worktree of the same repository.

 - A submodule worktree (whose name is $name) has its $GIT_DIR
   inside "modules/$name/" subdirectory of the $GIT_DIR of its
   superproject.

As long as the primary worktree or the superproject in these cases
are not bare, the pathname of these "looks like bare but not really"
directories will have "/.git/worktrees/" and "/.git/modules/" as a
substring in its leading part, and we can take advantage of the same
security guarantee allow git to work from these places.

Extend the earlier "in a directory called '.git' we are OK" logic
used for the primary worktree to also cover the secondary worktree's
and non-embedded submodule's $GIT_DIR, by moving the logic to a
helper function "is_implicit_bare_repo()".  We deliberately exclude
secondary worktrees and submodules of a bare repository, as these
are exactly what safe.bareRepository=explicit setting is designed to
forbid accesses to without an explicit GIT_DIR/--git-dir=<path>

Florian Schmidt 2541cba2d6 wt-status: don't find scissors line beyond buf len
If

  (a) There is a "---" divider in a commit message,

  (b) At some point beyond that divider, there is a cut-line (that is,
      "# ------------------------ >8 ------------------------") in the
      commit message,

  (c) the user does not explicitly set the "no-divider" option,

then "git interpret-trailers" will hang indefinitively.

This is because when (a) is true, find_end_of_log_message() will invoke
ignored_log_message_bytes() with a len that is intended to make it
ignore the part of the commit message beyond the divider. However,
ignored_log_message_bytes() calls wt_status_locate_end(), and that
function ignores the length restriction when it tries to locate the cut
line. If it manages to find one, the returned cutoff value is greater
than len. At this point, ignored_log_message_bytes() goes into an
infinite loop, because it won't advance the string parsing beyond len,
but the exit condition expects to reach cutoff.

Make wt_status_locate_end() honor the length parameter passed in, to
fix this issue.

In general, if wt_status_locate_end() is given a piece of the memory
that lacks NUL at all, strstr() may continue across page boundaries
and run into an unmapped page.  For our current callers, this is not
a problem, as all of them except one uses a memory owned by a strbuf
(which guarantees an implicit NUL-termination after its payload),
and the one exception in trailer.c:find_end_of_log_message() uses
strlen() to compute the length before calling this function.

Jeff Hostetler 0c1c3c861e t0211: demonstrate missing 'def_param' events for certain commands
Some Git commands fail to emit 'def_param' events for interesting
config and environment variable settings.

Add unit tests to demonstrate this.

Most commands are considered "builtin" and are based upon git.c.
These typically do emit 'def_param' events.  Exceptions are some of
the "query" commands, the "run-dashed" mechanism, and alias handling.

Commands built from remote-curl.c (instead of git.c), such as
"git-remote-https", do not emit 'def_param' events.

Likewise, "git-http-fetch" is built http-fetch.c and does not emit
them.

Jeff Hostetler 29c139ce78 fsmonitor: support case-insensitive events
Teach fsmonitor_refresh_callback() to handle case-insensitive
lookups if case-sensitive lookups fail on case-insensitive systems.
This can cause 'git status' to report stale status for files if there
are case issues/errors in the worktree.

The FSMonitor daemon sends FSEvents using the observed spelling
of each pathname.  On case-insensitive file systems this may be
different than the expected case spelling.

The existing code uses index_name_pos() to find the cache-entry for
the pathname in the FSEvent and clear the CE_FSMONITOR_VALID bit so
that the worktree scan/index refresh will revisit and revalidate the
path.

On a case-insensitive file system, the exact match lookup may fail
to find the associated cache-entry. This causes status to think that
the cached CE flags are correct and skip over the file.

Update event handling to optionally use the name-hash and dir-name-hash
if necessary.

Also update t7527 to convert the "test_expect_failure" to "_success"
now that we have fixed the bug.

Kristoffer Haugsbakk 8fbd903e58 branch: advise about ref syntax rules
git-branch(1) will error out if you give it a bad ref name. But the user
might not understand why or what part of the name is illegal.

The user might know that there are some limitations based on the *loose
ref* format (filenames), but there are also further rules for
easier integration with shell-based tools, pathname expansion, and
playing well with reference name expressions.

The man page for git-check-ref-format(1) contains these rules. Let’s
advise about it since that is not a command that you just happen
upon. Also make this advise configurable since you might not want to be
reminded every time you make a little typo.

Junio C Hamano 105ec9ae8d clean: further clean-up of implementation around "--force"
We clarified how "clean.requireForce" interacts with the "--dry-run"
option in the previous commit, both in the implementation and in the
documentation.  Even when "git clean" (without other options) is
required to be used with "--force" (i.e. either clean.requireForce
is unset, or explicitly set to true) to protect end-users from
casual invocation of the command by mistake, "--dry-run" does not
require "--force" to be used, because it is already its own
protection mechanism by being a no-op to the working tree files.

The previous commit, however, missed another clean-up opportunity
around the same area.  Just like in the "--dry-run" mode, the
command in the "--interactive" mode does not require "--force",
either.  This is because by going interactive and giving the end
user one more chance to confirm, the mode itself is serving as its
own protection mechanism.

Let's take things one step further, and unify the code that defines
interaction between "--force" and these two other options.  Just
like we added explanation for the reason why "--dry-run" does not
honor "clean.requireForce", give an explanation for the reason why
"--interactive" makes "clean.requireForce" to be ignored.

Finally, add some tests to show the interaction between "--force"
and "--interactive".  We already have tests that show interaction
between "--force" and "--dry-run", but didn't test "--interactive".

Ghanshyam Thakkar 8145a8fd02 setup: remove unnecessary variable
The TODO comment suggested to heed core.bare from template config file
if no command line override given. And the prev_bare_repository
variable seems to have been placed for this sole purpose as it is not
used anywhere else.

However, it was clarified by Junio [1] that such values (including
core.bare) are ignored intentionally and does not make sense to
propagate them from template config to repository config. Also, the
directories for the worktree and repository are already created, and
therefore the bare/non-bare decision has already been made, by the
point we reach the codepath where the TODO comment is placed.
Therefore, prev_bare_repository does not have a usecase with/without
supporting core.bare from template. And the removal of
prev_bare_repository is safe as proved by the later part of the
comment:

    "Unfortunately, the line above is equivalent to
        is_bare_repository_cfg = !work_tree;
    which ignores the config entirely even if no `--[no-]bare`
    command line option was present.

    To see why, note that before this function, there was this call:
        prev_bare_repository = is_bare_repository()
    expanding the right hand side:
        = is_bare_repository_cfg && !get_git_work_tree()
        = is_bare_repository_cfg && !work_tree
    note that the last simplification above is valid because nothing
    calls repo_init() or set_git_work_tree() between any of the
    relevant calls in the code, and thus the !get_git_work_tree()
    calls will return the same result each time.  So, what we are
    interested in computing is the right hand side of the line of
    code just above this comment:
        prev_bare_repository || !work_tree
        = is_bare_repository_cfg && !work_tree || !work_tree
        = !work_tree
    because "A && !B || !B == !B" for all boolean values of A & B."

Therefore, remove the TODO comment and remove prev_bare_repository
variable. Also, update relevant testcases and remove one redundant
testcase.

test -(e|d) does not provide a nice error message when we hit test
failures, so use test_path_exists, test_path_is_dir instead.

Rubén Justo c689c38bc2 completion: reflog show <log-options>
Let's add completion for <log-options> in "reflog show" so that the user
can easily discover uses like:

   $ git reflog --since=1.day.ago

Rubén Justo 85452a1d4b completion: reflog with implicit "show"
When no subcommand is specified to "reflog", we assume "show" [1]:

    $ git reflog -h
    usage: git reflog [show] [<log-options>] [<ref>]
    ...

This implicit "show" is not being completed correctly:

    $ git checkout -b default
    $ git reflog def<TAB><TAB>
    ... no completion options ...

The expected result is:

    $ git reflog default

This happens because we're completing references after seeing a valid
subcommand in the command line.  This prevents the implicit "show" from
working properly, but also introduces a new problem: it keeps offering
subcommand options when the subcommand is implicit:

    $ git checkout -b explore
    $ git reflog default ex<TAB>
    ...
    $ git reflog default expire

The expected result is:

    $ git reflog default explore

To fix this, complete references even if no subcommand is present, or in
other words when the subcommand is implicit "show".

Also, only include completion options for subcommands when completing
the right position in the command line.

René Scharfe 0d8a3097c7 parse-options: detect ambiguous self-negation
Git currently does not detect the ambiguity of an option that starts
with "no" like --notes and its negated form if given just --n or --no.
All Git commands with such options have other negatable options, and
we detect the ambiguity with them, so that's currently only a potential
problem for scripts that use git rev-parse --parseopt.

Let's fix it nevertheless, as there's no need for that confusion.  To
detect the ambiguity we have to loosen the check in register_abbrev(),
as an option is considered an alias of itself.  Add non-matching
negation flags as a criterion to recognize an option being ambiguous
with its negated form.

And we need to keep going after finding a non-negated option as an
abbreviated candidate and perform the negation checks in the same
loop.
