"what URL do we want to update this submodule?" and "are we
interested in this submodule?" are split into two distinct
concepts, and then the way used to express the latter got extended,
paving a way to make it easier to manage a project with many
submodules and make it possible to later extend use of multiple
worktrees for a project with submodules.

submodule add: respect submodule.active and submodule.<name>.active
submodule--helper init: set submodule.<name>.active
clone: teach --recurse-submodules to optionally take a pathspec
submodule init: initialize active submodules

In addition to adding submodule.<name>.url to the config, set
submodule.<name>.active to true unless submodule.active is configured
and the submodule's path matches the configured pathspec.

When initializing a submodule set the submodule.<name>.active config to
true if the module hasn't already been configured to be active by some
other means (e.g. a pathspec set in submodule.active).

Teach clone --recurse-submodules to optionally take a pathspec argument
which describes which submodules should be recursively initialized and
cloned. If no pathspec is provided, --recurse-submodules will
recursively initialize and clone all submodules by using a default
pathspec of ".". In order to construct more complex pathspecs,
--recurse-submodules can be given multiple times.
This also configures the 'submodule.active' configuration option to be
the given pathspec, such that any future invocation of `git submodule
update` will keep up with the pathspec.
Additionally the switch '--recurse' is removed from the Documentation as
well as marked hidden in the options array, to streamline the options
for submodules. A simple '--recurse' doesn't convey what is being
recursed, e.g. it could mean directories or trees (c.f. ls-tree) In a
lot of other commands we already have '--recurse-submodules' to mean
recursing into submodules, so advertise this spelling here as the
genuine option.

Teach `submodule init` to initialize submodules which have been
configured to be active by setting 'submodule.active' with a pathspec.
Now if no path arguments are given and 'submodule.active' is configured,
`init` will initialize all submodules which have been configured to be
active. If no path arguments are given and 'submodule.active' is not
configured, then `init` will retain the old behavior of initializing all
submodules.
This allows users to record more complex patterns as it saves retyping
them whenever you invoke update.

Currently the submodule.<name>.url config option is used to determine if
a given submodule is of interest to the user. This ends up being
cumbersome in a world where we want to have different submodules checked
out in different worktrees or a more generalized mechanism to select
which submodules are of interest.
In a future with worktree support for submodules, there will be multiple
working trees, each of which may only need a subset of the submodules
checked out. The URL (which is where the submodule repository can be
obtained) should not differ between different working trees.
It may also be convenient for users to more easily specify groups of
submodules they are interested in as opposed to running "git submodule
init <path>" on each submodule they want checked out in their working
tree.
To this end two config options are introduced, submodule.active and
submodule.<name>.active. The submodule.active config holds a pathspec
that specifies which submodules should exist in the working tree. The
submodule.<name>.active config is a boolean flag used to indicate if
that particular submodule should exist in the working tree.
Its important to note that submodule.active functions differently than
the other configuration options since it takes a pathspec. This allows
users to adopt at least two new workflows:
1. Submodules can be grouped with a leading directory, such that a
pathspec e.g. 'lib/' would cover all library-ish modules to allow
those who are interested in library-ish modules to set
"submodule.active = lib/" just once to say any and all modules in
'lib/' are interesting.
2. Once the pathspec-attribute feature is invented, users can label
submodules with attributes to group them, so that a broad pathspec
with attribute requirements, e.g. ':(attr:lib)', can be used to say
any and all modules with the 'lib' attribute are interesting.
Since the .gitattributes file, just like the .gitmodules file, is
tracked by the superproject, when a submodule moves in the
superproject tree, the project can adjust which path gets the
attribute in .gitattributes, just like it can adjust which path has
the submodule in .gitmodules.
Neither of these two additional configuration options solve the problem
of wanting different submodules checked out in different worktrees
because multiple worktrees share .git/config. Only once per-worktree
configurations become a reality can this be solved, but this is a
necessary preparatory step for that future.
Given these multiple ways to check if a submodule is of interest, the
more fine-grained submodule.<name>.active option has the highest order
of precedence followed by the pathspec check against submodule.active.
To ensure backwards compatibility, if neither of these options are set,
git falls back to checking the submodule.<name>.url option to determine
if a submodule is interesting.

Sync does some work determining what URLs should be used for a submodule
but then throws this work away if the submodule isn't active. Instead
perform the activity check earlier and skip inactive submodule in order
to avoid doing unnecessary work.

The definition of which submodules are of interest by the user
is tied to the configuration submodule.<name>.url; when it is
set to a non-empty string, it is of interest. We'd want to be
able to later change this definition, but there are many places
that explicitly check this condition in the scripted Porcelain.
Introduce the "is-active" subcommand to "submodule--helper", so
that the exact definition of what submodule is of interest can
be centrally defined (and changed in later steps). In a few
patches that follow, this helper is used to replace the explicit
checks of the configuration variable in scripts.

This is the endgame of the topic to avoid blindly falling back to
".git" when the setup sequence said we are _not_ in Git repository.
A corner case that happens to work right now may be broken by a
call to die("BUG").

When we default to ".git" without having done any kind of
repository setup, the results quite often do what the user
expects. But this has also historically been the cause of
some poorly behaved corner cases. These cases can be hard to
find, because they happen at the conjunction of two
relatively rare circumstances:
1. We are running some code which assumes there's a
repository present, but there isn't necessarily one
(e.g., low-level diff code triggered by "git diff
--no-index" might try to look at some repository data).
2. We have an unusual setup, like being in a subdirectory
of the working tree, or we have a .git file (rather
than a directory), or we are running a tool like "init"
or "clone" which may operate on a repository in a
different directory.
Our test scripts often cover (1), but miss doing (2) at the
same time, and so the fallback appears to work but has
lurking bugs. We can flush these bugs out by refusing to do
the fallback entirely., This makes potential problems a lot
more obvious by complaining even for "usual" setups.
This passes the test suite (after the adjustments in the
previous patches), but there's a risk of regression for any
cases where the fallback usually works fine but the code
isn't exercised by the test suite. So by itself, this
commit is a potential step backward, but lets us take two
steps forward once we've identified and fixed any such
instances.

to actually drop the support for the ancient syntax.

sha1dc/sha1.c wanted to check the endianness of the target platform
at compilation time and used a CPP macro with a rather overly
generic name, "BIGENDIAN", to pass the result of the check around
in the file. It wasn't prepared for the same macro set to 0
(false) by the platform to signal that the target is _not_ a big
endian box, and assumed that the endianness detection logic it has
alone would be the one that is setting the macro, resulting in a
breakage on Windows. This has been fixed by using a bit less
generic name for the same purpose.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
In an early part of sha1dc/sha1.c, the code checks the endianness of
the target platform by inspecting common CPP macros defined on
big-endian boxes, and sets BIGENDIAN macro to 1. If these common
CPP macros are not defined, the code declares that the target
platform is little endian and does nothing (most notably, it does
not #undef its BIGENDIAN macro).
The code that does so even has this comment
Note that all MSFT platforms are little endian,
so none of these will be defined under the MSC compiler.
and later, the defined-ness of the BIGENDIAN macro is used to switch
the implementation of sha1_load() macro.
One thing the code did not anticipate is that somebody might define
BIGENDIAN macro in some header it includes to 0 on a little-endian
target platform. Because the auto-detection based on common macros
do not touch BIGENDIAN macro when it detects a little-endian target,
such a definition is still valid and then defined-ness test will say
"Ah, BIGENDIAN is defined" and takes the wrong sha1_load().
As this auto-detection logic pretends as if it owns the BIGENDIAN
macro by ignoring the setting that may come from the outside and by
not explicitly unsetting when it decides that it is working for a
little-endian target, solve this problem without breaking that
assumption. Namely, we can rename BIGENDIAN this code uses to
something much less generic, i.e. SHA1DC_BIGENDIAN. For extra
protection, undef the macro on a little-endian target.
It is possible to work it around by instead #undef BIGENDIAN in
the auto-detection code, but a macro (or include) that happens later
in the code can be implemented in terms of BIGENDIAN on Windows and
it is possible that the implementation gets upset when it sees the
CPP macro undef'ed (instead of set to 0). Renaming the private macro
intended to be used only in this file to a less generic name relieves
us from having to worry about that kind of breakage.
