Since (ae8d08242 pathspec: pass directory indicator to
match_pathspec_item()) the path matching logic has been able to cope
with submodules without needing to strip off a trailing slash if a path
refers to a submodule.
ls-files is the only caller of 'parse_pathspec()' which relies on the
behavior of the PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP flag because it
uses the result to construct a common prefix of all provided pathspecs
which is then used to prune the index of all entries which don't have
that prefix. Since submodules entries in the index don't have a
trailing slash 'prune_cache()' will be overeager and prune a submodule
'sub' if the common prefix is 'sub/'. To correct this behavior, only
prune entries which don't match up to, but not including, a trailing
slash of the common prefix.
This is in preparation to remove the
PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP flag in a later patch.

with submodules without needing to strip off a trailing slash if a path
refers to a submodule.
Since the stripping the trailing slash is no longer necessary, remove
the PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag. In addition, factor
out the logic which dies if a path decends into a submodule so that it
can still be used as a check after a pathspec struct has been
initialized.

Currently 'git add' is the only command which dies when launched from an
unpopulated submodule (the place-holder directory for a submodule which
hasn't been checked out). This is triggered implicitly by passing the
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag to 'parse_pathspec()'.
Instead make this desire more explicit by creating a function
'die_in_unpopulated_submodule()' which dies if the provided 'prefix' has
a leading path component which matches a submodule in the the index.

* jk/shell-no-repository-that-begins-with-dash:
shell: disallow repo names beginning with dash
|
|
When a remote server uses git-shell, the client side will
connect to it like:
ssh server "git-upload-pack 'foo.git'"
and we literally exec ("git-upload-pack", "foo.git"). In
early versions of upload-pack and receive-pack, we took a
repository argument and nothing else. But over time they
learned to accept dashed options. If the user passes a
repository name that starts with a dash, the results are
confusing at best (we complain of a bogus option instead of
a non-existent repository) and malicious at worst (the user
can start an interactive pager via "--help").
We could pass "--" to the sub-process to make sure the
user's argument is interpreted as a branch name. I.e.:
git-upload-pack -- -foo.git
But adding "--" automatically would make us inconsistent
with a normal shell (i.e., when git-shell is not in use),
where "-foo.git" would still be an error. For that case, the
client would have to specify the "--", but they can't do so
reliably, as existing versions of git-shell do not allow
more than a single argument.
The simplest thing is to simply disallow "-" at the start of
the repo name argument. This hasn't worked either with or
without git-shell since version 1.0.0, and nobody has
complained.
Note that this patch just applies to do_generic_cmd(), which
runs upload-pack, receive-pack, and upload-archive. There
are two other types of commands that git-shell runs:
- do_cvs_cmd(), but this already restricts the argument to
be the literal string "server"
- admin-provided commands in the git-shell-commands
directory. We'll pass along arbitrary arguments there,
so these commands could have similar problems. But these
commands might actually understand dashed arguments, so
we cannot just block them here. It's up to the writer of
the commands to make sure they are safe. With great
power comes great responsibility.

In the scripted version of the interactive rebase, there was no internal
representation of the todo list; it was re-read before every command.
That allowed the hack that an `exec` command could append (or even
completely rewrite) the todo list.
This hack was broken by the partial conversion of the interactive rebase
to C, and this patch reinstates it.
We also add a small test to verify that this fix does not regress in the
future.

The previous step added a path zzzzzzzz to the index, and then used
"sed" to replace this string to yyyyyyyy to create a test case where
the checksum at the end of the file does not match the contents.
Unfortunately, use of "sed" on a non-text file is not portable.
Instead, use a Perl script that seeks to the end and modifies the
last byte of the file (where we _know_ stores the trailing
checksum).

Our array-reverse algorithm does the usual "walk from both
ends, swapping elements". We can quit when the two indices
are equal, since:
1. Swapping an element with itself is a noop.
2. If i and j are equal, then in the next iteration i is
guaranteed to be bigge than j, and we will exit the
loop.
So exiting the loop on equality is slightly more efficient.
And more importantly, the new SWAP() macro does not expect
to handle noop swaps; it will call memcpy() with the same src
and dst pointers in this case. It's unclear whether that
causes a problem on any platforms by violating the
"overlapping memory" constraint of memcpy, but it does cause
valgrind to complain.

But that's clearly nonsense. xstrdup() will never return

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
refs on that <remote>, not all refs.
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,
and not how git-push is documented, so I'm not fixing that case, but
adding a failing TODO test for it.

git-archimport has an option to register archives at

That means this feature is presumably broken. I'll leave the

The only caller of this function passes in a static buffer
returned from git_path(). This looks dangerous at first
glance, but turns out to be OK because the first thing we do
is xstrdup() the result.
Let's turn this into a git_pathdup(). That's slightly more
efficient (no extra copy), and makes it easier to audit for
dangerous git_path() invocations.
Since there's only a single caller, let's just set this
default path inside the init function. That makes the memory
ownership clear.

When performing an interactive rebase in split-index mode,
the commit message that one should rework when squashing commits
can contain some garbage instead of the usual concatenation of
both of the commit messages.
The code uses git_path() to compute the shared index filename, and
passes it to check_and_freshen_file() as its argument; there is no
guarantee that the rotating pathname buffer passed as argument will
stay valid during the life of this call. Make our own copy before
calling the function and pass the copy as its argument to avoid this
risky pattern.

As explained in the document. This option has an advantage over the
command sequence "git worktree add && git worktree lock": there will be
no gap that somebody can accidentally "prune" the new worktree (or soon,
explicitly "worktree remove" it).
"worktree add" does keep a lock on while it's preparing the worktree.
If --lock is specified, this lock remains after the worktree is created.

Teach has_dir_name() to see if the path of the new item
is greater than the last path in the index array before
attempting to search for it.
has_dir_name() is looking for file/directory collisions
in the index and has to consider each sub-directory
prefix in turn. This can cause multiple binary searches
for each path.
During operations like checkout, merge_working_tree()
populates the new index in sorted order, so we expect
to be able to append in many cases.
This commit is part 2 of 2. This commit handles the
additional possible short-cuts as we look at each
sub-directory prefix.
The net-net gains for add_index_entry_with_check() and
both had_dir_name() commits are best seen for very

Created t/perf/inflate-repo.sh to alter an EXISTING repo
to have a set of large commits. This can be used to create
a branch with 1M+ files in repositories like git.git or
linux.git, but with more realistic content. It does this
by making multiple copies of the entire worktree in a series
of sub-directories.
The branch name and ballast structure created by both scripts
match, so either script can be used to generate very large
test repositories for the following perf test.
Created t/perf/p0006-read-tree-checkout.sh to measure

Config file reading order is important because each file can override
values in the previous files and this is expected behavior. Normally
we read in this order, all in do_git_config_sequence():
1. $HOME/.gitconfig
2. $GIT_DIR/config
3. config from command line
However in read_early_config() the order may be swapped a bit if
setup_git_directory() has not been called:
1. $HOME/.gitconfig
2. $GIT_DIR/config is NOT read because .git dir is not found _yet_
3. config from command line
4. $GIT_DIR/config is now READ (after discover_git_directory() call)
The reading at step 4 could override config at step 3, which is not
the expectation.
Now that we could pass the .git dir around, we could feed
discover_git_directory() back to step 2, so that it works again, and
remove step 4.

Don't assume that the current working directory is the root of the
repository. Correctly generate the path for the recursing child
processes by building it from the work_tree() root instead. Otherwise if
we run ls-files using --git-dir or --work-tree it will not work
correctly as it attempts to change directory into a potentially invalid
location. Best case, it doesn't exist and we produce an error. Worst
case we cd into the wrong location and unknown behavior occurs.
Add a new test which highlights this possibility.

If setup_git_directory() and friends have not been called,
get_git_dir() (because of includeIf.gitdir:XXX) would lead to
die("BUG: setup_git_env called without repository");
There are two cases when a config file could be read before $GIT_DIR
is located.
The first one is check_repository_format(), where we read just the one
file $GIT_DIR/config to check if we could understand this
repository. This case should be safe. We do not parse include
directives, which can only be triggered from git_config_with_options,
but setup code uses a lower-level function. The concerned variables
should never be hidden away behind includes anyway.
The second one is triggered in check_pager_config() when we're about
to run an external git command. We might be able to find $GIT_DIR in
this case, which is exactly what read_early_config() does (and also is
what check_pager_config() uses). Conditional includes and
get_git_dir() could be triggered by the first
git_config_with_options() call there, before discover_git_directory()
is used as a fallback $GIT_DIR detection.
Detect this special "early reading" case, pass down the $GIT_DIR,
either from previous setup or detected by discover_git_directory(),
and make conditional include use it.

Since commit e77aa336f116 ("ls-files: optionally recurse into
submodules", 2016-10-07) ls-files has known how to recurse into
submodules when displaying files.
Unfortunately this fails for certain cases, including when nesting more
than one submodule, called from within a submodule that itself has
submodules, or when the GIT_DIR environemnt variable is set.
Prior to commit b58a68c1c187 ("setup: allow for prefix to be passed to
git commands", 2017-03-17) this resulted in an error indicating that
--prefix and --super-prefix were incompatible.
After this commit, instead, the process loops forever with a GIT_DIR set
to the parent and continuously reads the parent submodule files and
recursing forever.
Fix this by preparing the environment properly for submodules when
setting up the child process. This is similar to how other commands such
as grep behave.
This was not caught by the original tests because the scenario is
avoided if the submodules are created separately and not stored as the
standard method of putting the submodule git directory under
.git/modules/<name>. We can update the test to show the failure by the
addition of "git submodule absorbgitdirs" to the test case. However,
note that this new test would run forever without the necessary fix in
this patch.

Currently, fetch-pack prints a confusing error message ("expected
ACK/NAK") when the server it's communicating with sends a pkt-line
starting with "ERR". Replace it with a less confusing error message.
Also update the documentation describing the fetch-pack/upload-pack
protocol (pack-protocol.txt) to indicate that "ERR" can be sent in the
place of "ACK" or "NAK". In practice, this has been done for quite some
time by other Git implementations (e.g. JGit sends "want $id not valid")
and by Git itself (since commit bdb31ea: "upload-pack: report "not our
ref" to client", 2017-02-23) whenever a "want" line references an object
that it does not have. (This is uncommon, but can happen if a repository
is garbage-collected during a negotiation.)

Use reference iteration rather than `do_for_each_entry_in_dir()` in
the definition of `files_pack_refs()`. This makes the code shorter and
easier to follow, because the logic can be inline rather than spread
between the main function and a callback function, and it removes the
need to use `pack_refs_cb_data` to preserve intermediate state.
This removes the last callers of `entry_resolves_to_object()` and
`get_loose_ref_dir()`, so delete those functions.

Use reference iteration rather than do_for_each_entry_in_dir() in the
definition of commit_packed_refs().
Note that an internal consistency check that was previously done in
`write_packed_entry_fn()` is not there anymore. This is actually an
improvement:
The old error message was emitted when there is an entry in the
packed-ref cache that is not `REF_KNOWS_PEELED`, and when we attempted
to peel the reference, the result was `PEEL_INVALID`,
`PEEL_IS_SYMREF`, or `PEEL_BROKEN`. Since a packed ref cannot be a
symref, `PEEL_IS_SYMREF` and `PEEL_BROKEN` can be ruled out. So we're
left with `PEEL_INVALID`.
An entry without `REF_KNOWS_PEELED` can get into the packed-refs cache
in the following two ways:
* The reference was read from a `packed-refs` file that didn't have
the `fully-peeled` attribute. In that case, we *don't want* to emit
an error, because the broken value is presumably a stale value of
the reference that is now masked by a loose version of the same
reference (which we just don't happen to be packing this time). This
is a perfectly legitimate situation and doesn't indicate that the
repository is corrupt. The old code incorrectly emits an error
message in this case. (It was probably never reported as a bug
because this scenario is rare.)
* The reference was a loose reference that was just added to the
packed ref cache by `files_packed_refs()` via
`pack_if_possible_fn()` in preparation for being packed. The latter
function refuses to pack a reference for which
`entry_resolves_to_object()` returns false, and otherwise calls
`peel_entry()` itself and checks the return value. So an entry added
this way should always have `REF_KNOWS_PEELED` and shouldn't trigger
the error message in either the old code or the new.

It is a leveling violation for `ref_cache` to know about
`files_ref_store` or that it should call `read_loose_refs()` to lazily
fill cache directories. So instead, have its constructor take as an
argument a callback function that it should use for lazy-filling, and
change `files_ref_store` to supply a pointer to function
`read_loose_refs` (renamed to `loose_fill_ref_dir`) when creating the
ref cache for its loose refs.
This means that we can generify the type of the back-pointer in
`struct ref_cache` from `files_ref_store` to `ref_store`.

Instead of keeping a pointer to the `ref_store` in every `ref_dir`
entry, store it once in `struct ref_cache`, and change `struct
ref_dir` to include a pointer to its containing `ref_cache` instead.
This makes it easier to add to the information that is accessible from
a `ref_dir` without increasing the size of every `ref_dir` instance.
Note that previously, every `ref_dir` pointed at the containing
`files_ref_store` regardless of whether it was a part of the loose or
packed reference cache. Now we have to be sure to initialize the
instances to point at the correct containing `ref_cache`. So change
`create_dir_entry()` to take a `ref_cache` parameter, and change its
callers to pass the correct `ref_cache` depending on the purpose of
the new `dir_entry`.

The `ref_cache` code is currently too tightly coupled to
`files-backend`, making the code harder to understand and making it
awkward for new code to use `ref_cache` (as we indeed have planned).
Start loosening that coupling by splitting `ref_cache` into a separate
module.
This commit moves code, adds declarations, and changes the visibility
of some functions, but doesn't change any code.
The modules are still too tightly coupled, but the situation will be
improved in subsequent commits.
