Each of these were checked with
gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE}
to ensure that removing the direct inclusion of the header actually
resulted in that header no longer being included at all (i.e. that
no other header pulled it in transitively).
...except for a few cases where we verified that although the header
was brought in transitively, nothing from it was directly used in
that source file. These cases were:
* builtin/credential-cache.c
* builtin/pull.c
* builtin/send-pack.c

If both directories D1 and D2 already exists, and further there is a
filesystem entity D2/D1, "git mv D1 D2" would fail, and we get an
error message that says:
"cannot move directory over file, source=D1, destination=D2/D1"
regardless of the type of existing "D2/D1". If it is a file, the
message is correct, but if it is a directory, it is not (we could
make the D2/D1 directory a union of its original contents and what
was in D1/, but that is not what we do).
The code that decies to issue the error message only checks for
existence of "D2/D1" and does not care what kind of thing sits at
the path.
Rephrase the message to say
"destination already exists, source=D1, destination=D2/D1"
that would be suitable for any kind of thing being in the way.

When moving a directory onto another with `git mv` various checks are
performed. One of of these validates that the destination is not existing.
When calling `lstat` on the destination path and it fails as the path
doesn't exist, some environments seem to overwrite the passed in
`stat` memory nonetheless (I observed this issue on debian 12 of x86_64,
running on OrbStack on ARM, emulated with Rosetta).
This would affect the code that followed as it would still acccess a now
modified `st` structure, which now seems to contain uninitialized memory.
`S_ISDIR(st_dir_mode)` would then typically return false causing the code
to run into a bad case.
The fix avoids overwriting the existing `st` structure, providing an
alternative that exists only for that purpose.
Note that this patch minimizes complexity instead of stack-frame size.

alloc_nr, ALLOC_GROW, and ALLOC_GROW_BY are commonly used macros for
dynamic array allocation. Moving these macros to git-compat-util.h with
the other alloc macros focuses alloc.[ch] to allocation for Git objects
and additionally allows us to remove inclusions to alloc.h from files
that solely used the above macros.

For the functions defined in read-cache.c, move their declarations from
cache.h to a new header, read-cache-ll.h. Also move some related inline
functions from cache.h to read-cache.h. The purpose of the
read-cache-ll.h/read-cache.h split is that about 70% of the sites don't
need the inline functions and the extra headers they include.

hash.h depends upon and includes repository.h, due to the definition and
use of the_hash_algo (defined as the_repository->hash_algo). However,
most headers trying to include hash.h are only interested in the layout
of the structs like object_id. Move the parts of hash.h that do not
depend upon repository.h into a new file hash-ll.h (the "low level"
parts of hash.h), and adjust other files to use this new header where
the convenience inline functions aren't needed.
This allows hash.h and object.h to be fairly small, minimal headers. It
also exposes a lot of hidden dependencies on both path.h (which was
brought in by repository.h) and repository.h (which was previously
implicitly brought in by object.h), so also adjust other files to be
more explicit about what they depend upon.

Apply the rule added in [1] to change "cache_name_pos" to
"index_name_pos", which allows us to get rid of another
"USE_THE_INDEX_COMPATIBILITY_MACROS" macro.
The replacement of "USE_THE_INDEX_COMPATIBILITY_MACROS" here with
"USE_THE_INDEX_VARIABLE" is a manual change on top, now that these
files only use "&the_index", and don't need any compatibility
macros (or functions).

Apply "index-compatibility.pending.cocci" rule to "builtin/*", but
exclude those where we conflict with in-flight changes.
As a result some of them end up using only "the_index", so let's have
them use the more narrow "USE_THE_INDEX_VARIABLE" rather than
"USE_THE_INDEX_COMPATIBILITY_MACROS".
Manual changes not made by coccinelle, that were squashed in:
* Whitespace-wrap argument lists for repo_hold_locked_index(),
repo_read_index_preload() and repo_refresh_and_write_index(), in cases
where the line became too long after the transformation.
* Change "refresh_cache()" to "refresh_index()" in a comment in
"builtin/update-index.c".
* For those whose call was followed by perror("<macro-name>"), change
it to perror("<function-name>"), referring to the new function.

Mostly apply the part of "index-compatibility.pending.cocci" that
renames the global variables like "active_nr", which are a shorthand
to referencing (in that case) a struct member as "the_index.cache_nr".
In doing so move more of "index-compatibility.pending.cocci" to
"index-compatibility.cocci".
In the case of "active_nr" we'd have a textual conflict with
"ab/various-leak-fixes" in "next"[1]. Let's exclude that specific case
while moving the rule over from "pending".

removals in "cache.h", and the update to the '*.cocci" rules. The rest

Since 4aab5b46f44 (Make read-cache.c "the_index" free., 2007-04-01)
we've been undergoing a slow migration away from these macros, but
haven't made much progress since f8adbec9fea (cache.h: flip
NO_THE_INDEX_COMPATIBILITY_MACROS switch, 2019-01-24).
Let's move forward a bit by changing the users of those macros that
are rare enough that we can convert them in one go, and then remove
the compatibility shim.
The only manual change to the C code here is to "cache.h", the rest is
all the result of applying the new "index-compatibility.cocci".
Even though it's a one-off, let's keep the coccinelle rules for
now. We'll extend them in subsequent commits, and this will help
anything that's in-flight or out-of-tree to migrate.

"git mv A B" in a sparsely populated working tree can be asked to
move a path from a directory that is "in cone" to another directory
that is "out of cone". Handling of such a case has been improved.
* sy/mv-out-of-cone:
builtin/mv.c: fix possible segfault in add_slash()
mv: check overwrite for in-to-out move
advice.h: add advise_on_moving_dirty_path()
mv: cleanup empty WORKING_DIRECTORY
mv: from in-cone to out-of-cone
mv: remove BOTH from enum update_mode
mv: check if <destination> is a SKIP_WORKTREE_DIR
mv: free the with_slash in check_dir_in_index()
mv: rename check_dir_in_index() to empty_dir_has_sparse_contents()
t7002: add tests for moving from in-cone to out-of-cone
|
|
A possible segfault was introduced in c08830de41 (mv: check if
<destination> is a SKIP_WORKTREE_DIR, 2022-08-09).
When running t7001 with SANITIZE=address, problem appears when running:
git mv path1/path2/ .
or
git mv directory ../
or
any <destination> that makes dest_path[0] an empty string.
The add_slash() call could segfault when path argument to it is an empty
string, because it makes an out-of-bounds read to decide if an extra
slash '/' needs to be appended to it.
As add_slash() is used to make sure that a valid pathname to a file in
the given directory can be made by appending a filename after the value
returned from it, if path is an empty string, we want to return it
as-is. The path to a file "F" in the top-level of the working tree
(i.e. path=="") is formed by appending "F" after "" (i.e. path) without
any slash in between.
So, just like the case where a non-empty path already ends with a slash,
return an empty path as-is.

Originally, moving an in-cone <source> to an out-of-cone <destination>
was not possible, mainly because such <destination> is a directory that
is not present in the working tree.
Change the behavior so that we can move an in-cone <source> to
out-of-cone <destination> when --sparse is supplied.
Notice that <destination> can also be an out-of-cone file path, rather
than a directory.
Such <source> can be either clean or dirty, and moving it results in
different behaviors:
A clean move should move <source> to <destination> in the index (do
*not* create <destination> in the worktree), then delete <source> from
the worktree.
A dirty move should move the <source> to the <destination>, both in the
working tree and the index, but should *not* remove the resulted path
from the working tree and should *not* turn on its CE_SKIP_WORKTREE bit.
Optional reading
================
We are strict about cone mode when <destination> is a file path.
The reason is that some of the previous tests that use no-cone mode in
t7002 are keep breaking, mainly because the `dst_mode = SPARSE;` line
added in this patch.
Most features developed in both "from-out-to-in" and "from-in-to-out"
only care about cone mode situation, as no-cone mode is becoming
irrelevant. And because assigning `SPARSE` to `dst_mode` when the
repo is in no-cone mode causes miscellaneous bugs, we should just leave
this new functionality to be exclusive cone mode and save some time.

Originally, <destination> is assumed to be in the working tree. If it is
not found as a directory, then it is determined to be either a regular file
path, or error out if used under the second form (move into a directory)
of 'git-mv'. Such behavior is not ideal, mainly because Git does not
look into the index for <destination>, which could potentially be a
SKIP_WORKTREE_DIR, which we need to determine for the later "moving from
in-cone to out-of-cone" patch.
Change the logic so that Git first check if <destination> is a directory
with all its contents sparsified (a SKIP_WORKTREE_DIR).
If <destination> is such a sparse directory, then we should modify the
index the same way as we would if this were a non-sparse directory. We
must be careful to ensure that the <destination> is marked with
SKIP_WORKTREE_DIR.
Also add a `dst_w_slash` to reuse the result from `add_slash()`, which
was everywhere and can be simplified.

Method check_dir_in_index() introduced in b91a2b6594 (mv: add
check_dir_in_index() and solve general dir check issue, 2022-06-30)
does not describe its intent and behavior well.
Change its name to empty_dir_has_sparse_contents(), which more
precisely describes its purpose.
Reverse the return values, check_dir_in_index() return 0 for success
and 1 for failure; reverse the values so empty_dir_has_sparse_contents()
return 1 for success and 0 for failure. These values are more intuitive
because 1 usually means "has" and 0 means "not found".
Also modify the documentation to better align with the method's
intent and behavior.

Apply Coccinelle rule to turn raw memmove() into MOVE_ARRAY() cpp
macro, which would improve maintainability and readability.
* jc/builtin-mv-move-array:
builtin/mv.c: use the MOVE_ARRAY() macro instead of memmove()
|
|
The variables 'source', 'destination', and 'submodule_gitfile' are
all of type "const char **", and an element of such an array is of
"type const char *", but these memmove() calls were written as if
these variables are of type "char **".
Once these memmove() calls are fixed to use the correct type to
compute the number of bytes to be moved, e.g.
- memmove(source + i, source + i + 1, n * sizeof(char *));
+ memmove(source + i, source + i + 1, n * sizeof(const char *));
existing contrib/coccinelle/array.cocci rules can recognize them as
candidates for turning into MOVE_ARRAY().
While at it, use CALLOC_ARRAY() instead of xcalloc() to allocate the
modes[] array that is involved in the change.

Originally, "git mv" a sparse file from out-of-cone to
in-cone does not update the moved file's sparsity (remove its
SKIP_WORKTREE bit). And the corresponding cache entry is, unexpectedly,
not checked out in the working tree.
Update the behavior so that:
1. Moving from out-of-cone to in-cone removes the SKIP_WORKTREE bit from
corresponding cache entry.
2. The moved cache entry is checked out in the working tree to reflect
the updated sparsity.

Since cmd_mv() does not operate on cache entries and instead directly
checks the filesystem, we can only use path_in_sparse_checkout() as a
mechanism for seeing if a path is sparse or not. Be sure to skip
returning a failure if '-k' is specified.
To ensure that the advice around sparse paths is the only reason a move
failed, be sure to check this as the very last thing before inserting
into the src_for_dst list.
The tests cover a variety of cases such as whether the target is tracked
or untracked, and whether the source or destination are in or outside of
the sparse-checkout definition.

The following sequence, on a case-insensitive file system,
(strictly speeking with core.ignorecase=true)
leads to an assertion failure and leaves .git/index.lock behind.
git init
echo foo >foo
git add foo
git mv foo FOO
git mv foo bar
This regression was introduced in Commit 9b906af657,
"git-mv: improve error message for conflicted file"
The bugfix is to change the "file exist case-insensitive in the index"
into the correct "file exist (case-sensitive) in the index".
This avoids the "assert" later in the code and keeps setting up the
"ce" pointer for ce_stage(ce) done in the next else if.
This fixes

'git mv' has always complained about renaming a conflicted
file, as it cannot handle multiple index entries for one file.
However, the error message it uses has been the same as the
one for an untracked file:
fatal: not under version control, src=...
which is patently wrong. Distinguish the two cases and
add a test to make sure we produce the correct message.

Code clean-up to adjust to a more recent lockfile API convention that
allows lockfile instances kept on the stack.
* ma/lockfile-cleanup:
lock_file: move static locks into functions
lock_file: make function-local locks non-static
refs.c: do not die if locking fails in `delete_pseudoref()`
refs.c: do not die if locking fails in `write_pseudoref()`
t/helper/test-write-cache: clean up lock-handling

Placing `struct lock_file`s on the stack used to be a bad idea, because
the temp- and lockfile-machinery would keep a pointer into the struct.
But after 076aa2cbd (tempfile: auto-allocate tempfiles on heap,
2017-09-05), we can safely have lockfiles on the stack. (This applies
even if a user returns early, leaving a locked lock behind.)
Each of these `struct lock_file`s is used from within a single function.
Move them into the respective functions to make the scope clearer and
drop the staticness.
For good measure, I have inspected these sites and come to believe that
they always release the lock, with the possible exception of bailing out
using `die()` or `exit()` or by returning from a `cmd_foo()`.
As pointed out by Jeff King, it would be bad if someone held on to a
`struct lock_file *` for some reason. After some grepping, I agree with
his findings: no-one appears to be doing that.
After this commit, the remaining occurrences of "static struct
lock_file" are locks that are used from within different functions. That
is, they need to remain static. (Short of more intrusive changes like
passing around pointers to non-static locks.)

Moving a submodule that itself has submodule in it with "git mv"
forgot to make necessary adjustment to the nested sub-submodules;
now the codepath learned to recurse into the submodules.
* sb/submodule-move-nested:
submodule: fixup nested submodules after moving the submodule
submodule-config: remove submodule_from_cache
submodule-config: add repository argument to submodule_from_{name, path}
submodule-config: allow submodule_free to handle arbitrary repositories
grep: remove "repo" arg from non-supporting funcs
submodule.h: drop declaration of connect_work_tree_and_git_dir
|

connect_work_tree_and_git_dir is used to connect a submodule worktree with
its git directory and vice versa after events that require a reconnection
such as moving around the working tree. As submodules can have nested
submodules themselves, we'd also want to fix the nested submodules when
asked to. Add an option to recurse into the nested submodules and connect
them as well.
As submodules are identified by their name (which determines their git
directory in relation to their superproject's git directory) internally
and by their path in the working tree of the superproject, we need to
make sure that the mapping of name <-> path is kept intact. We can do
that in the git-mv command by writing out the gitmodules file first
and then forcing a reload of the submodule config machinery.
