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 c4a09cc9ccb (Merge branch 'hw/advise-ng', 2020-03-25), a new API for
accessing advice variables was introduced and deprecated `advice_config`
in favor of a new array, `advice_setting`.
This patch ports all but two uses which read the status of the global
`advice_` variables over to the new `advice_enabled` API. We'll deal
with advice_add_embedded_repo and advice_graft_file_deprecated
separately.

Add a new submodule--helper subcommand `run-update-procedure` that runs
the update procedure if the SHA1 of the submodule does not match what
the superproject expects.
This is an intermediate change that works towards total conversion of
`submodule update` from shell to C.
Specific error codes are returned so that the shell script calling the
subcommand can take a decision on the control flow, and preserve the
error messages across subsequent recursive calls of `cmd_update`.
This change is more focused on doing a faithful conversion, so for now we
are not too concerned with trying to reduce subprocess spawns.

Let's rename 'compute_submodule_clone_url()' to 'resolve_relative_url()'
to make it clear that this internal helper need not be used exclusively
for computing submodule clone URLs.
Since the original 'resolve-relative-url' subcommand and its C entry
point has been removed in c461095ae3 (submodule--helper: remove
resolve-relative-url subcommand, 2021-07-02), this rename can be done
without causing any confusion about which function it actually binds to.

Introduce the 'add' subcommand to `submodule--helper.c` that does all
the work 'submodule add' past the parsing of flags.
We also remove the constness of the sm_path field of the `add_data`
struct. This is needed so that it can be modified by
normalize_path_copy().
As with the previous conversions, this is meant to be a faithful
conversion with no modification to the behaviour of `submodule add`.

This part of `sync_submodule()` is doing the same thing that
`compute_submodule_clone_url()` is doing. Let's reuse that helper here.
Note that this change adds a small overhead where we allocate and free
the 'remote' twice, but that is a small price to pay for the higher
level of abstraction we get.

Refactor the helper function to resolve a relative url, by reusing the
existing `compute_submodule_clone_url()` function.
`compute_submodule_clone_url()` performs the same work that
`resolve_relative_url()` is doing, so we eliminate this code repetition
by moving the former function's definition up, and calling it inside
`resolve_relative_url()`.

Let's modify the interface to `compute_submodule_clone_url()` function
by adding two more arguments, so that we can reuse this in various parts
of `submodule--helper.c` that follow a common pattern, which is--read
the remote url configuration of the superproject and then call
`relative_url()`.
This function is nearly identical to `resolve_relative_url()`, the only
difference being the extra warning message. We can add a quiet flag to
it, to suppress that warning when not needed, and then refactor
`resolve_relative_url()` by using this function, something we will do in
the next patch.
We also rename the local variable 'relurl' to avoid potential confusion
with the 'rel_url' parameter while we are at it.
Having this functionality factored out will be useful for converting the
rest of `submodule add` in subsequent patches.

* ar/submodule-add-config:
submodule--helper: introduce add-config subcommand
|
|
Add a new "add-config" subcommand to `git submodule--helper` with the
goal of converting part of the shell code in git-submodule.sh related to
`git submodule add` into C code. This new subcommand sets the
configuration variables of a newly added submodule, by registering the
url in local git config, as well as the submodule name and path in the
.gitmodules file. It also sets 'submodule.<name>.active' to "true" if
the submodule path has not already been covered by any pathspec
specified in 'submodule.active'.
This is meant to be a faithful conversion from shell to C, although we
add comments to areas that could be improved in future patches, after
the conversion has settled.

relative_url() populates sb. In the normal return path, its buffer is
detached using strbuf_detach(). However the early return path does
nothing with sb, which means that sb's memory is leaked - therefore
we add a release to avoid this leak.
The reset is also only necessary for the normal return path, hence we
move it down to after the early-return to avoid unnecessary work.

Up until recently, object IDs did not have an algorithm member, only a
hash. Consequently, it was possible to share one null (all-zeros)
object ID among all hash algorithms. Now that we're going to be
handling objects from multiple hash algorithms, it's important to make
sure that all object IDs have a correct algorithm field.
Introduce a per-algorithm null OID, and add it to struct hash_algo.
Introduce a wrapper function as well, and use it everywhere we used to
use the null_oid constant.

When commands are started from a subdirectory, they may have to
compare the path to the subdirectory (called prefix and found out
from $(pwd)) with the tracked paths. On macOS, $(pwd) and
readdir() yield decomposed path, while the tracked paths are
usually normalized to the precomposed form, causing mismatch. This
has been fixed by taking the same approach used to normalize the
command line arguments.
* tb/precompose-prefix-too:
MacOS: precompose_argv_prefix()
|
|
The following sequence leads to a "BUG" assertion running under MacOS:
DIR=git-test-restore-p
Adiarnfd=$(printf 'A\314\210')
DIRNAME=xx${Adiarnfd}yy
mkdir $DIR &&
cd $DIR &&
git init &&
mkdir $DIRNAME &&
cd $DIRNAME &&
echo "Initial" >file &&
git add file &&
echo "One more line" >>file &&
echo y | git restore -p .
Initialized empty Git repository in /tmp/git-test-restore-p/.git/
BUG: pathspec.c:495: error initializing pathspec_item
Cannot close git diff-index --cached --numstat
[snip]
The command `git restore` is run from a directory inside a Git repo.
Git needs to split the $CWD into 2 parts:
The path to the repo and "the rest", if any.
"The rest" becomes a "prefix" later used inside the pathspec code.
As an example, "/path/to/repo/dir-inside-repå" would determine
"/path/to/repo" as the root of the repo, the place where the
configuration file .git/config is found.
The rest becomes the prefix ("dir-inside-repå"), from where the
pathspec machinery expands the ".", more about this later.
If there is a decomposed form, (making the decomposing visible like this),
"dir-inside-rep°a" doesn't match "dir-inside-repå".
Git commands need to:
(a) read the configuration variable "core.precomposeunicode"
(b) precocompose argv[]
(c) precompose the prefix, if there was any
The first commit,
76759c7dff53 "git on Mac OS and precomposed unicode"
addressed (a) and (b).
The call to precompose_argv() was added into parse-options.c,
because that seemed to be a good place when the patch was written.
Commands that don't use parse-options need to do (a) and (b) themselfs.
The commands `diff-files`, `diff-index`, `diff-tree` and `diff`
learned (a) and (b) in
commit 90a78b83e0b8 "diff: run arguments through precompose_argv"
Branch names (or refs in general) using decomposed code points
resulting in decomposed file names had been fixed in
commit 8e712ef6fc97 "Honor core.precomposeUnicode in more places"
The bug report from above shows 2 things:
- more commands need to handle precomposed unicode
- (c) should be implemented for all commands using pathspecs
Solution:
precompose_argv() now handles the prefix (if needed), and is renamed into
precompose_argv_prefix().
Inside this function the config variable core.precomposeunicode is read
into the global variable precomposed_unicode, as before.
This reading is skipped if precomposed_unicode had been read before.
The original patch for preocomposed unicode, 76759c7dff53, placed
precompose_argv() into parse-options.c
Now add it into git.c::run_builtin() as well. Existing precompose
calls in diff-files.c and others may become redundant, and if we
audit the callflows that reach these places to make sure that they
can never be reached without going through the new call added to
run_builtin(), we might be able to remove these existing ones.
But in this commit, we do not bother to do so and leave these
precompose callsites as they are. Because precompose() is
idempotent and can be called on an already precomposed string
safely, this is safer than removing existing calls without fully
vetting the callflows.
There is certainly room for cleanups - this change intends to be a bug fix.
Cleanups needs more tests in e.g. t/t3910-mac-os-precompose.sh, and should
be done in future commits.

The 'grep' check in test 4 of t7421 resulted in the failure of t7421 on
Windows due to a different error message
error: cannot spawn git: No such file or directory
instead of
fatal: exec 'rev-parse': cd to 'my-subm' failed: No such file or directory
Tighten up the check to compute 'src_abbrev' by guarding the
'verify_submodule_committish()' call using `p->status !='D'`, so that
the former isn't called in case of non-existent submodule directory,
consequently, there is no such error message on any execution
environment. The same need not be implemented for 'dst_abbrev' and is
rather redundant since the conditional 'if (S_ISGITLINK(p->mod_dst))'
already guards the 'verify_submodule_committish()' when we have a
status of 'D'.
Therefore, eliminate the 'grep' check in t7421. Instead, verify the
absence of an error message by doing a 'test_must_be_empty' on the
file containing the error.

In the ensure_core_worktree() function, we load the core.worktree value
of the submodule repository using repo_config_get_string(). This
function copies the string, but we never free it, leaking the memory.
We can instead use the "tmp" version of that function to avoid the
allocation at all. We don't have to worry about lifetime issues, since
we never even look at the value (we just want to know if it's set).

There are two functions to get a single config string:
- git_config_get_string()
- git_config_get_string_const()
One might naively think that the first one allocates a new string and
the second one just points us to the internal configset storage. But
in fact they both allocate a new copy; the second one exists only to
avoid having to cast when using it with a const global which we never
intend to free.
The documentation for the function explains that clearly, but it seems
I'm not alone in being surprised by this. Of 17 calls to the function,
13 of them leak the resulting value.
We could obviously fix these by adding the appropriate free(). But it
would be simpler still if we actually had a non-allocating way to get
the string. There's git_config_get_value() but that doesn't quite do
what we want. If the config key is present but is a boolean with no
value (e.g., "[foo]bar" in the file), then we'll get NULL (whereas the
string versions will print an error and die).
So let's introduce a new variant, git_config_get_string_tmp(), that
behaves as these callers expect. We need a new name because we have new
semantics but the same function signature (so even if we converted the
four remaining callers, topics in flight might be surprised). The "tmp"
is because this value should only be held onto for a short time. In
practice it's rare for us to clear and refresh the configset,
invalidating the pointer, but hopefully the "tmp" makes callers think
about the lifetime. In each of the converted cases here the value only
needs to last within the local function or its immediate caller.

The prepare_to_clone_next_submodule() function has a few local-variable
strbufs. We use strbuf_reset() throughout the function to reuse the
buffers over and over. But at the end of the function we also use
strbuf_reset() as they go out of scope, which means we end up leaking
their heap buffers. This should be strbuf_release() instead.
These were introduced by 48308681b0 (git submodule update: have a
dedicated helper for cloning, 2016-02-29), but it doesn't seem to have
the same mistake elsewhere. Likewise, I looked for other instances of
the pattern in the submodule--helper file but couldn't find any.

The shell version had to call $diff_cmd twice, once to find the modified
modules cared by the user and then again, with that list of modules
to do various operations for computing the summary of those modules.
On the other hand, the C version does not need a second call to
$diff_cmd since it reuses the module list from the first call to do the
aforementioned tasks.
In the C version, we use the combination of setting a child process'
working directory to the submodule path and then calling
'prepare_submodule_repo_env()' which also sets the 'GIT_DIR' to '.git',
so that we can be certain that those spawned processes will not access
the superproject's ODB by mistake.
A behavioural difference between the C and the shell version is that the
shell version outputs two line feeds after the 'git log' output when run
outside of the tests while the C version outputs one line feed in any
case. The reason for this is that the shell version calls log with
'--pretty=format:<fmt>' whose output is followed by two echo
calls; 'format' does not have "terminator" semantics like its 'tformat'
counterpart. So, the log output is terminated by a newline only when
invoked by the user and not when invoked from the scripts. This results
in the one & two line feed differences in the shell version.
On the other hand, the C version calls log with '--pretty=<fmt>'
which is equivalent to '--pretty:tformat:<fmt>' which is then
followed by a 'printf("\n")'. Due to its "terminator" semantics the
log output is always terminated by newline and hence one line feed in
any case.
Also, when we try to pass an option-like argument after a non-option
argument, for instance:
git submodule summary HEAD --foo-bar
(or)
git submodule summary HEAD --cached
That argument would be treated like a path to the submodule for which
the user is requesting a summary. So, the option ends up having no
effect. Though, passing '--quiet' is an exception to this:
git submodule summary HEAD --quiet
While 'summary' doesn't support '--quiet', we don't get an output for
the above command as '--quiet' is treated as a path which means we get
an output only if a submodule whose path is '--quiet' exists.
The error message in case of computing a summary for non-existent
submodules in the C version is different from that of the shell version.
Since the new error message is not marked for translation, change the
'test_i18ngrep' in t7421.4 to 'grep'.

Many `submodule--helper` subcommands follow the convention that a struct
defines their callback data, and the declaration of that struct is
followed immediately by a macro to use in static initializers, without
any separating empty line.
Let's align the `init`, `status` and `sync` subcommands with that convention.

The "argc" and "argv" names made sense when the struct was argv_array,
but now they're just confusing. Let's rename them to "nr" (which we use
for counts elsewhere) and "v" (which is rather terse, but reads well
when combined with typical variable names like "args.v").
Note that we have to update all of the callers immediately. Playing
tricks with the preprocessor is hard here, because we wouldn't want to
rewrite unrelated tokens.

Code which split an argv_array call across multiple lines, like:
argv_array_pushl(&args, "one argument",
"another argument", "and more",
NULL);
was recently mechanically renamed to use strvec, which results in
mis-matched indentation like:
strvec_pushl(&args, "one argument",
"another argument", "and more",
NULL);
Let's fix these up to align the arguments with the opening paren. I did
this manually by sifting through the results of:
git jump grep 'strvec_.*,$'
and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

We eventually want to drop the argv_array name and just use strvec
consistently. There's no particular reason we have to do it all at once,
or care about interactions between converted and unconverted bits.
Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).
This patch converts all of the files in builtin/ to keep the diff to a
manageable size.
The conversion was done purely mechanically with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe '
s/ARGV_ARRAY/STRVEC/g;
s/argv_array/strvec/g;
'
and then selectively staging files with "git add builtin/". We'll deal
with any indentation/style fallouts separately.

The name of the primary branch in existing repositories, and the
default name used for the first branch in newly created
repositories, is made configurable, so that we can eventually wean
ourselves off of the hardcoded 'master'.
* js/default-branch-name:
contrib: subtree: adjust test to change in fmt-merge-msg
testsvn: respect `init.defaultBranch`
remote: use the configured default branch name when appropriate
clone: use configured default branch name when appropriate
init: allow setting the default for the initial branch name via the config
init: allow specifying the initial branch name for the new repository
docs: add missing diamond brackets
submodule: fall back to remote's HEAD for missing remote.<name>.branch
send-pack/transport-helper: avoid mentioning a particular branch
fmt-merge-msg: stop treating `master` specially
|
|
When `remote.<name>.branch` is not configured, `git submodule update`
currently falls back to using the branch name `master`. A much better
idea, however, is to use the remote `HEAD`: on all Git servers running
reasonably recent Git versions, the symref `HEAD` points to the main
branch.
Note: t7419 demonstrates that there _might_ be use cases out there that
_expect_ `git submodule update --remote` to update submodules to the
remote `master` branch even if the remote `HEAD` points to another
branch. Arguably, this patch makes the behavior more intuitive, but
there is a slight possibility that this might cause regressions in
obscure setups.
Even so, it should be okay to fix this behavior without anything like a
longer transition period:
- The `git submodule update --remote` command is not really common.
- Current Git's behavior when running this command is outright
confusing, unless the remote repository's current branch _is_ `master`
(in which case the proposed behavior matches the old behavior).
- If a user encounters a regression due to the changed behavior, the fix
is actually trivial: setting `submodule.<name>.branch` to `master`
will reinstate the old behavior.
