When check_has_commit() is called on a missing submodule, initialization
of the struct repository fails, but it attempts to clear the struct
anyway (which is a fatal error). This bug is masked by its only caller,
submodule_has_commits(), first calling add_submodule_odb(). The latter
fails if the submodule does not exist, making submodule_has_commits()
exit early and not invoke check_has_commit().
Fix this bug, and because calling add_submodule_odb() is no longer
necessary as of 13a2f620b2 (submodule: pass repo to
check_has_commit(), 2021-10-08), remove that call too.
This is the last caller of add_submodule_odb(), so remove that
function. (Submodule ODBs are still added as alternates via
add_submodule_odb_by_path().)

"git fetch --recurse-submodules" only considers populated
submodules (i.e. submodules that can be found by iterating the index),
which makes "git fetch" behave differently based on which commit is
checked out. As a result, even if the user has initialized all submodules
correctly, they may not fetch the necessary submodule commits, and
commands like "git checkout --recurse-submodules" might fail.
Teach "git fetch" to fetch cloned, changed submodules regardless of
whether they are populated. This is in addition to the current behavior
of fetching populated submodules (which is always attempted regardless
of what was fetched in the superproject, or even if nothing was fetched
in the superproject).
A submodule may be encountered multiple times (via the list of
populated submodules or via the list of changed submodules). When this
happens, "git fetch" only reads the 'populated copy' and ignores the
'changed copy'. Amend the verify_fetch_result() test helper so that we
can assert on which 'copy' is being read.

To improve the submodules UX, we would like to teach Git to handle
branches in submodules. Start this process by teaching "git branch" the
--recurse-submodules option so that "git branch --recurse-submodules
topic" will create the `topic` branch in the superproject and its
submodules.
Although this commit does not introduce breaking changes, it does not
work well with existing --recurse-submodules commands because "git
branch --recurse-submodules" writes to the submodule ref store, but most
commands only consider the superproject gitlink and ignore the submodule
ref store. For example, "git checkout --recurse-submodules" will check
out the commits in the superproject gitlinks (and put the submodules in
detached HEAD) instead of checking out the submodule branches.
Because of this, this commit introduces a new configuration value,
`submodule.propagateBranches`. The plan is for Git commands to
prioritize submodule ref store information over superproject gitlinks if
this value is true. Because "git branch --recurse-submodules" writes to
submodule ref stores, for the sake of clarity, it will not function
unless this configuration value is set.
This commit also includes changes that support working with submodules
from a superproject commit because "branch --recurse-submodules" (and
future commands) need to read .gitmodules and gitlinks from the
superproject commit, but submodules are typically read from the
filesystem's .gitmodules and the index's gitlinks. These changes are:
* add a submodules_of_tree() helper that gives the relevant
information of an in-tree submodule (e.g. path and oid) and
initializes the repository
* add is_tree_submodule_active() by adding a treeish_name parameter to
is_submodule_active()
* add the "submoduleNotUpdated" advice to advise users to update the
submodules in their trees
Incidentally, fix an incorrect usage string that combined the 'list'
usage of git branch (-l) with the 'create' usage; this string has been
incorrect since its inception, a8dfd5eac4 (Make builtin-branch.c use
parse_options., 2007-10-07).

Move various *_INIT macros to use designated initializers. This helps
readability. I've only picked those leftover macros that were not
touched by another in-flight series of mine which changed others, but
also how initialization was done.
In the case of SUBMODULE_ALTERNATE_SETUP_INIT I've left an explicit
initialization of "error_mode", even though
SUBMODULE_ALTERNATE_ERROR_IGNORE itself is defined as "0". Let's not
peek under the hood and assume that enum fields we know the value of
will stay at "0".
The change to "TESTSUITE_INIT" in "t/helper/test-run-command.c" was
part of an earlier on-list version[1] of c90be786da9 (test-tool
run-command: fix flip-flop init pattern, 2021-09-11).

2017-07-10) to omit specifying "alloc" and "len", as we do with other

Code refactoring.
* jt/submodule-name-to-gitdir:
submodule: extract path to submodule gitdir func
|
|
We currently store each submodule gitdir in ".git/modules/<name>", but
this has problems with some submodule naming schemes, as described in a
comment in submodule_name_to_gitdir() in this patch.
Extract the determination of the location of a submodule's gitdir into
its own function submodule_name_to_gitdir(). For now, the problem
remains unsolved, but this puts us in a better position for finding a
solution.
This was motivated, at $DAYJOB, by a part of Android's repo hierarchy
[1]. In particular, there is a repo "build", and several repos of the
form "build/<name>".
This is based on earlier work by Brandon Williams [2].

In the parent commit, Git was taught to add submodule ODBs as alternates
lazily, but grep does not use this because it computes the path to add
directly, not going through add_submodule_odb(). Add an equivalent to
add_submodule_odb() that takes the exact ODB path and teach grep to use
it.

Teach Git to add submodule ODBs as alternates to the object store of
the_repository only upon the first access of an object not in
the_repository, and not when add_submodule_odb() is called.
This provides a means of gradually migrating from accessing a
submodule's object through alternates to accessing a submodule's object
by explicitly passing its repository object. Any Git command can declare
that it might access submodule objects by calling add_submodule_odb()
(as they do now), but the submodule ODBs themselves will not be added
until needed, so individual commands and/or combinations of arguments
can be migrated one by one.
[The advantage of explicit repository-object passing is code clarity (it
is clear which repository an object read is from), performance (there is
no need to linearly search through all submodule ODBs whenever an object
is accessed from any repository, whether superproject or submodule), and
the possibility of future features like partial clone submodules (which
right now is not possible because if an object is missing, we do not
know which repository to lazy-fetch into).]
This commit also introduces an environment variable that a test may set
to make the actual registration of alternates fatal, in order to
demonstrate that its codepaths do not need this registration.

Several methods specify that they take a 'struct index_state' pointer
with the 'const' qualifier because they intend to only query the data,
not change it. However, we will be introducing a step very low in the
method stack that might modify a sparse-index to become a full index in
the case that our queries venture inside a sparse-directory entry.
This change only removes the 'const' qualifiers that are necessary for
the following change which will actually modify the implementation of
index_name_stage_pos().

The helper functions: show_submodule_summary(),
prepare_submodule_summary() and print_submodule_summary() are used by
the builtin_diff() function in diff.c to generate a summary of
submodules in the context of a diff. Functions with similar names are to
be introduced in the upcoming port of submodule's summary subcommand.
So, rename the helper functions to '*_diff_submodule_summary()' to avoid
ambiguity.

The name "argv-array" isn't very good, because it describes what the
data type can be used for (program argument arrays), not what it
actually is (a dynamically-growing string array that maintains a
NULL-terminator invariant). This leads to people being hesitant to use
it for other cases where it would actually be a good fit. The existing
name is also clunky to use. It's overly long, and the name often leads
to saying things like "argv.argv" (i.e., the field names overlap with
variable names, since they're describing the use, not the type). Let's
give it a more neutral name.
I settled on "strvec" because "vector" is the name for a dynamic array
type in many programming languages. "strarray" would work, too, but it's
longer and a bit more awkward to say (and don't we all say these things
in our mind as we type them?).
A more extreme direction would be a generic data structure which stores
a NULL-terminated of _any_ type. That would be easy to do with void
pointers, but we'd lose some type safety for the existing cases. Plus it
raises questions about memory allocation and ownership. So I limited
myself here to changing names only, and not semantics. If we do find a
use for that more generic data type, we could perhaps implement it at a
lower level and then provide type-safe wrappers around it for strings.
But that can come later.
This patch does the minimum to convert the struct and function names in
the header and implementation, leaving a few things for follow-on
patches:
- files retain their original names for now
- struct field names are retained for now
- there's a preprocessor compat layer that lets most users remain the
same for now. The exception is headers which made a manual forward
declaration of the struct. I've converted them (and their dependent
function declarations) here.

Currently it is technically possible to let a submodule's git
directory point right into the git dir of a sibling submodule.
Example: the git directories of two submodules with the names `hippo`
and `hippo/hooks` would be `.git/modules/hippo/` and
`.git/modules/hippo/hooks/`, respectively, but the latter is already
intended to house the former's hooks.
In most cases, this is just confusing, but there is also a (quite
contrived) attack vector where Git can be fooled into mistaking remote
content for file contents it wrote itself during a recursive clone.
Let's plug this bug.
To do so, we introduce the new function `validate_submodule_git_dir()`
which simply verifies that no git dir exists for any leading directories
of the submodule name (if there are any).
Note: this patch specifically continues to allow sibling modules names
of the form `core/lib`, `core/doc`, etc, as long as `core` is not a
submodule name.
This fixes CVE-2019-1387.

When a submodules work tree is removed, we should unset its core.worktree
setting as the worktree is no longer present. This is not just in line
with the conceptual view of submodules, but it fixes an inconvenience
for looking at submodules that are not checked out:
git clone --recurse-submodules git://github.com/git/git && cd git &&
git checkout --recurse-submodules v2.13.0
git -C .git/modules/sha1collisiondetection log
fatal: cannot chdir to '../../../sha1collisiondetection': \
No such file or directory
With this patch applied, the final call to git log works instead of dying
in its setup, as the checkout will unset the core.worktree setting such
that following log will be run in a bare repository.
This patch covers all commands that are in the unpack machinery, i.e.
checkout, read-tree, reset. A follow up patch will address
"git submodule deinit", which will also make use of the new function
submodule_unset_core_worktree(), which is why we expose it in this patch.
This patch was authored as 4fa4f90ccd (submodule: unset core.worktree if
no working tree is present, 2018-06-12), which was reverted as part of
f178c13fda (Revert "Merge branch 'sb/submodule-core-worktree'",
2018-09-07). The revert was needed as the nearby commit e98317508c
(submodule: ensure core.worktree is set after update, 2018-06-18) is
faulty and at the time of 7e25437d35 (Merge branch
'sb/submodule-core-worktree', 2018-07-18) we could not revert the faulty
commit only, as they were depending on each other: If core.worktree is
unset, we have to have ways to ensure that it is set again once
the working tree reappears again.
Now that 4d6d6ef1fc (Merge branch 'sb/submodule-update-in-c', 2018-09-17),
specifically 74d4731da1 (submodule--helper: replace
connect-gitdir-workingtree by ensure-core-worktree, 2018-08-13) is
present, we already check and ensure core.worktree is set when
populating a new work tree, such that we can re-introduce the commits
that unset core.worktree when removing the worktree.

"struct index_state *" as argument even if it's not really used. My
bad.
Instead of deleting this argument and fixing up all call sites. Let's
take this opportunity to remove some the_repository instead because
there's one or two in this function (and two more in its callback).
The callers can also get rid of some the_repository.

Introduce a helper function named is_writing_gitmodules_ok() to verify
that the .gitmodules file is safe to write.
The function name follows the scheme of is_staging_gitmodules_ok().
The two symbolic constants GITMODULES_INDEX and GITMODULES_HEAD are used
to get help from the C preprocessor in preventing typos, especially for
future users.
This is in preparation for a future change which teaches git how to read
.gitmodules from the index or from the current branch if the file is not
available in the working tree.
The rationale behind the check is that writing to .gitmodules requires
the file to be present in the working tree, unless a brand new
.gitmodules is being created (in which case the .gitmodules file would
not exist at all: neither in the working tree nor in the index or in the
current branch).
Expose the functionality also via a "submodule-helper config
--check-writeable" command, as git scripts may want to perform the check
before modifying submodules configuration.

changes made to 00624d608cc69bd62801c93e74d1ea7a7ddd6598.
v2.19.0-rc0~165^2~1 (submodule: ensure core.worktree is set after
update, 2018-06-18) assumes an "absorbed" submodule layout, where the
submodule's Git directory is in the superproject's .git/modules/
directory and .git in the submodule worktree is a .git file pointing
there. In particular, it uses $GIT_DIR/modules/$name to find the
submodule to find out whether it already has core.worktree set, and it
uses connect_work_tree_and_git_dir if not, resulting in
fatal: could not open sub/.git for writing
The context behind that patch: v2.19.0-rc0~165^2~2 (submodule: unset
core.worktree if no working tree is present, 2018-06-12) unsets
core.worktree when running commands like "git checkout
--recurse-submodules" to switch to a branch without the submodule. If
a user then uses "git checkout --no-recurse-submodules" to switch back
to a branch with the submodule and runs "git submodule update", this
patch is needed to ensure that commands using the submodule directly
are aware of the path to the worktree.
It is late in the release cycle, so revert the whole 3-patch series.
We can try again later for 2.20.

Code hygiene improvement for the header files.
* en/incl-forward-decl:
Remove forward declaration of an enum
compat/precompose_utf8.h: use more common include guard style
urlmatch.h: fix include guard
Move definition of enum branch_track from cache.h to branch.h
alloc: make allocate_alloc_state and clear_alloc_state more consistent
Add missing includes and forward declarations
|
|
I looped over the toplevel header files, creating a temporary two-line C
program for each consisting of
#include "git-compat-util.h"
#include $HEADER
This patch is the result of manually fixing errors in compiling those
tiny programs.

When a submodules work tree is removed, we should unset its core.worktree
setting as the worktree is no longer present. This is not just in line
with the conceptual view of submodules, but it fixes an inconvenience
for looking at submodules that are not checked out:
git clone --recurse-submodules git://github.com/git/git && cd git &&
git checkout --recurse-submodules v2.13.0
git -C .git/modules/sha1collisiondetection log
fatal: cannot chdir to '../../../sha1collisiondetection': \
No such file or directory
With this patch applied, the final call to git log works instead of dying
in its setup, as the checkout will unset the core.worktree setting such
that following log will be run in a bare repository.
This patch covers all commands that are in the unpack machinery, i.e.
checkout, read-tree, reset. A follow up patch will address
"git submodule deinit", which will also make use of the new function
submodule_unset_core_worktree(), which is why we expose it in this patch.

"git pull -recurse-submodules --rebase", when the submodule
repository's history did not have anything common between ours and
the upstream's, failed to execute. We need to fetch from them to
continue even in such a case.

By code restructuring of submodule merge in merge-recursive,
informational messages from the codepath are now given using the
same mechanism as other output, and honor the merge.verbosity
configuration. The code also learned to give a few new messages
when a submodule three-way merge resolves cleanly when one side
records a descendant of the commit chosen by the other side.
* sb/submodule-merge-in-merge-recursive:
merge-recursive: give notice when submodule commit gets fast-forwarded
merge-recursive: i18n submodule merge output and respect verbosity
submodule.c: move submodule merging to merge-recursive.c

If "git pull --recurse-submodules --rebase" is invoked when the current
branch and its corresponding remote-tracking branch have no merge base,
a "bad object" fatal error occurs. This issue was introduced with commit
a6d7eb2c7a ("pull: optionally rebase submodules (remote submodule
changes only)", 2017-06-23), which also introduced this feature.
This is because cmd_pull() in builtin/pull.c thus invokes
submodule_touches_in_range() with a null OID as the first parameter.
Ensure that this case works, and document what happens in this case.

In a later patch we want to improve submodule merging by using the output()
function in merge-recursive.c for submodule merges to deliver a consistent
UI to users.
To do so we could either make the output() function globally available
so we can use it in submodule.c#merge_submodule(), or we could integrate
the submodule merging into the merging code. Choose the later as we
generally want to move submodules closer into the core.
Therefore we move any function related to merging submodules
(merge_submodule(), find_first_merges() and print_commit) to
merge-recursive.c. We'll keep add_submodule_odb() in submodule.c as it
is used by other submodule functions. While at it, add a TODO note that
we do not really like the function add_submodule_odb().
This commit is best viewed with --color-moved.

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}

grep: remove "repo" arg from non-supporting funcs
submodule.h: drop declaration of connect_work_tree_and_git_dir
|

The function connect_work_tree_and_git_dir is declared in both submodule.h
and dir.h, such that one of them is redundant. As the function is
implemented in dir.c, drop the declaration from submodule.h

Instead of implicitly relying on the global 'the_index', convert
'get_next_submodule()' to use the index of the repository stored in the
callback data 'struct submodule_parallel_fetch'.
Since this removes the last user of the index compatibility macros,
define 'NO_THE_INDEX_COMPATIBILITY_MACROS' to prevent future users of
these macros in submodule.c.

Commit 883e248b8 (fsmonitor: teach git to optionally utilize a file
system monitor to speed up detecting new or changed files., 2017-09-22)
introduced a call to 'ce_match_stat()' in 'is_staging_gitmodules_ok()'
which implicitly relys on the the global 'the_index' instead of the
passed in 'struct index_state'. Fix this by changing the call to
'ie_match_stat()' and using the passed in index_state struct.
