Subject: Makefile: use common template for GIT-BUILD-OPTIONS

The "GIT-BUILD-OPTIONS" file is generated by our build systems to
propagate built-in features and paths to our tests. The generation is
done ad-hoc, where both our Makefile and the CMake build instructions
simply echo a bunch of strings into the file. This makes it very hard to
figure out what variables are expected to exist and what format they
have, and the written variables can easily get out of sync between build
systems.

Introduce a new "GIT-BUILD-OPTIONS.in" template to address this issue.
This has multiple advantages:

  - It demonstrates which built options exist in the first place.

  - It can serve as a spot to document the build options.

  - Some build systems complain when not all variables could be
    substituted, alerting us of mismatches. Others don't, but if we
    forgot to substitute such variables we now have a bogus string that
    will likely cause our tests to fail, if they have any meaning in the
    first place.

Backfill values that we didn't yet set in our CMake build instructions.
While at it, remove the `SUPPORTS_SIMPLE_IPC` variable that we only set
up in CMake as it isn't used anywhere.

This change requires us to adapt the setup of TEST_OUTPUT_DIRECTORY in
"test-lib.sh" such that it does not get overwritten after sourcing when
it has been set up via the environment. This is the only instance I
could find where we rely on ordering on variables.

Subject: Makefile: consistently use @PLACEHOLDER@ to substitute

We have a bunch of placeholders in our scripts that we replace at build
time, for example by using sed(1). These placeholders come in three
different formats: @PLACEHOLDER@, @@PLACEHOLDER@@ and ++PLACEHOLDER++.

Next to being inconsistent it also creates a bit of a problem with
CMake, which only supports the first syntax in its `configure_file()`
function. To work around that we instead manually replace placeholders
via string operations, which is a hassle and removes safeguards that
CMake has to verify that we didn't forget to replace any placeholders.
Besides that, other build systems like Meson also support the CMake
syntax.

Unify our codebase to consistently use the syntax supported by such
build systems.

Subject: Makefile: refactor GIT-VERSION-GEN to be reusable

Our "GIT-VERSION-GEN" script always writes the "GIT-VERSION-FILE" into
the current directory, where the expectation is that it should exist in
the source directory. But other build systems that support out-of-tree
builds may not want to do that to keep the source directory pristine,
even though CMake currently doesn't care.

Refactor the script such that it won't write the "GIT-VERSION-FILE"
directly anymore, but instead knows to replace @PLACEHOLDERS@ in an
arbitrary input file. This allows us to simplify the logic in CMake to
determine the project version, but can also be reused later on in order
to generate other files that need to contain version information like
our "git.rc" file.

While at it, change the format of the version file by removing the
spaces around the equals sign. Like this we can continue to include the
file in our Makefiles, but can also start to source it in shell scripts
in subsequent steps.

Subject: Makefile: propagate Git version via generated header

We set up a couple of preprocessor macros when compiling Git that
propagate the version that Git was built from to `git version` et al.
The way this is set up makes it harder than necessary to reuse the
infrastructure across the different build systems.

Refactor this such that we generate a "version-def.h" header via
`GIT-VERSION-GEN` instead.

Subject: Makefile: generate "git.rc" via GIT-VERSION-GEN

The "git.rc" is used on Windows to embed information like the project
name and version into the resulting executables. As such we need to
inject the version information, which we do by using preprocessor
defines. The logic to do so is non-trivial and needs to be kept in sync
with the different build systems.

Refactor the logic so that we generate "git.rc" via `GIT-VERSION-GEN`.

Subject: Makefile: consistently use PERL_PATH

When injecting the Perl path into our scripts we sometimes use '@PERL@'
while we othertimes use '@PERL_PATH@'. Refactor the code use the latter
consistently, which makes it easier to reuse the same logic for multiple
scripts.

Subject: Makefile: use "generate-perl.sh" to massage Perl library

Extend "generate-perl.sh" such that it knows to also massage the Perl
library files. There are two major differences:

  - We do not read in the Perl header. This is handled by matching on
    whether or not we have a Perl shebang.

  - We substitute some more variables, which we read in via our
    GIT-BUILD-OPTIONS.

Adapt both our Makefile and the CMake build instructions to use this.

Subject: Makefile: extract script to massage Python scripts

Extract a script that massages Python scripts. This provides a couple of
benefits:

  - The build logic is deduplicated across Make, CMake and Meson.

  - CMake learns to rewrite scripts as-needed at build time instead of
    only writing them at configure time.

Furthermore, we will use this script when introducing Meson to
deduplicate the logic across build systems.

Subject: Makefile: refactor generators to be PWD-independent

We have multiple scripts that generate headers from other data. All of
these scripts have the assumption built-in that they are executed in the
current source directory, which makes them a bit unwieldy to use during
out-of-tree builds.

Refactor them to instead take the source directory as well as the output
file as arguments.

Subject: Makefile: allow "bin-wrappers/" directory to exist

The "bin-wrappers/" directory gets created by our build system and is
populated with one script for each of our binaries. There isn't anything
inherently wrong with the current layout, but it is somewhat hard to
adapt for out-of-tree build systems.

Adapt the layout such that our "bin-wrappers/" directory always exists
and contains our "wrap-for-bin.sh" script to make things a little bit
easier for subsequent steps.

Subject: Makefile: simplify building of templates

When we install Git we also install a set of default templates that both
git-init(1) and git-clone(1) populate into our build directories. The
way the pristine templates are laid out in our source directory is
somewhat weird though: instead of reconstructing the actual directory
hierarchy in "templates/", we represent directory separators with "--".

The only reason I could come up with for why we have this is the
"branches/" directory, which is supposed to be empty when installing it.
And as Git famously doesn't store empty directories at all we have to
work around this limitation.

Now the thing is that the "branches/" directory is a leftover to how
branches used to be stored in the dark ages. gitrepository-layout(5)
lists this directory as "slightly deprecated", which I would claim is a
strong understatement. I have never encountered anybody using it today
and would be surprised if it even works as expected. So having the "--"
hack in place for an item that is basically unused, unmaintained and
deprecated doesn't only feel unreasonable, but installing that entry by
default may also cause confusion for users that do not know what this is
supposed to be in the first place.

Remove this directory from our templates and, now that we do not require
the workaround anymore, restructure the templates to form a proper
hierarchy. This makes it way easier for build systems to install these
templates into place.

We should likely think about removing support for "branch/" altogether,
but that is outside of the scope of this patch series.

-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
-   merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
-   it is deleted.  If you need to build on top of it to correct
-   earlier mistakes, a new topic branch is created by forking at
-   the tip of the "master".  This is not strictly necessary, but
-   it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
-   branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next".  Young
-    topic branches can have stupid mistakes you would rather
-    clean up before publishing, and things that have not been
-    merged into other branches can be easily rebased without
-    affecting other people.  But once it is published, you would
-    not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
-    Then you can delete it.  More importantly, you should not
-    build on top of it -- other people may already want to
-    change things related to the topic as patches against your
-    "master", so if you need further changes, it is better to
-    fork the topic (perhaps with the same name) afresh from the
-    tip of "master".
-
-Let's look at this example:
-
-		   o---o---o---o---o---o---o---o---o---o "next"
-		  /       /           /           /
-		 /   a---a---b A     /           /
-		/   /               /           /
-	       /   /   c---c---c---c B         /
-	      /   /   /             \         /
-	     /   /   /   b---b C     \       /
-	    /   /   /   /             \     /
-    ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished.  It has been fully merged up to "master" and "next",
-   and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
-	git rev-list ^master ^topic next
-	git rev-list ^master        next
-
-	if these match, topic has not merged in next at all.
-
-To compute (2):
-
-	git rev-list master..topic
-
-	if this is empty, it is fully merged to "master".

-# An example hook script to update a checked-out tree on a git push.
-#
-# This hook is invoked by git-receive-pack(1) when it reacts to git
-# push and updates reference(s) in its repository, and when the push
-# tries to update the branch that is currently checked out and the
-# receive.denyCurrentBranch configuration variable is set to
-# updateInstead.
-#
-# By default, such a push is refused if the working tree and the index
-# of the remote repository has any difference from the currently
-# checked out commit; when both the working tree and the index match
-# the current commit, they are updated to match the newly pushed tip
-# of the branch. This hook is to be used to override the default
-# behaviour; however the code below reimplements the default behaviour
-# as a starting point for convenient modification.
-#
-# The hook receives the commit with which the tip of the current
-# branch is going to be updated:
-commit=$1
-
-# It can exit with a non-zero status to refuse the push (when it does
-# so, it must not modify the index or the working tree).
-die () {

-
-# Or it can make any necessary changes to the working tree and to the
-# index to bring them to the desired state when the tip of the current
-# branch is updated to the new commit, and exit with a zero status.
-#
-# For example, the hook can simply run git read-tree -u -m HEAD "$1"
-# in order to emulate git fetch that is run in the reverse direction
-# with git push, as the two-tree form of git read-tree -u -m is
-# essentially the same as git switch or git checkout that switches
-# branches while keeping the local changes in the working tree that do
-# not interfere with the difference between the branches.
-
-# The below is a more-or-less exact translation to shell of the C code
-# for the default behaviour for git's push-to-checkout hook defined in
-# the push_to_deploy() function in builtin/receive-pack.c.
-#
-# Note that the hook will be executed from the repository directory,

+
+This sample hook safeguards topic branches that have been
+published from being rewound.
+
+The workflow assumed here is:
+
+ * Once a topic branch forks from "master", "master" is never
+   merged into it again (either directly or indirectly).
+
+ * Once a topic branch is fully cooked and merged into "master",
+   it is deleted.  If you need to build on top of it to correct
+   earlier mistakes, a new topic branch is created by forking at
+   the tip of the "master".  This is not strictly necessary, but
+   it makes it easier to keep your history simple.
+
+ * Whenever you need to test or publish your changes to topic
+   branches, merge them into "next" branch.
+
+The script, being an example, hardcodes the publish branch name
+to be "next", but it is trivial to make it configurable via
+$GIT_DIR/config mechanism.
+
+With this workflow, you would want to know:
+
+(1) ... if a topic branch has ever been merged to "next".  Young
+    topic branches can have stupid mistakes you would rather
+    clean up before publishing, and things that have not been
+    merged into other branches can be easily rebased without
+    affecting other people.  But once it is published, you would
+    not want to rewind it.
+
+(2) ... if a topic branch has been fully merged to "master".
+    Then you can delete it.  More importantly, you should not
+    build on top of it -- other people may already want to
+    change things related to the topic as patches against your
+    "master", so if you need further changes, it is better to
+    fork the topic (perhaps with the same name) afresh from the
+    tip of "master".
+
+Let's look at this example:
+
+		   o---o---o---o---o---o---o---o---o---o "next"
+		  /       /           /           /
+		 /   a---a---b A     /           /
+		/   /               /           /
+	       /   /   c---c---c---c B         /
+	      /   /   /             \         /
+	     /   /   /   b---b C     \       /
+	    /   /   /   /             \     /
+    ---o---o---o---o---o---o---o---o---o---o---o "master"
+
+
+A, B and C are topic branches.
+
+ * A has one fix since it was merged up to "next".
+
+ * B has finished.  It has been fully merged up to "master" and "next",
+   and is ready to be deleted.
+
+ * C has not merged to "next" at all.
+
+We would want to allow C to be rebased, refuse A, and encourage
+B to be deleted.
+
+To compute (1):
+
+	git rev-list ^master ^topic next
+	git rev-list ^master        next
+
+	if these match, topic has not merged in next at all.
+
+To compute (2):
+
+	git rev-list master..topic
+
+	if this is empty, it is fully merged to "master".

From 7e0730c8baaac43fcf0366e686066ec2c1fc2f31 Mon Sep 17 00:00:00 2001

Subject: t: better support for out-of-tree builds

Our in-tree builds used by the Makefile use various different build
directories scattered around different locations. The paths to those
build directories have to be propagated to our tests such that they can
find the contained files. This is done via a mixture of hardcoded paths
in our test library and injected variables in our bin-wrappers or
"GIT-BUILD-OPTIONS".

The latter two mechanisms are preferable over using hardcoded paths. For
one, we have all paths which are subject to change stored in a small set
of central files instead of having the knowledge of build paths in many
files. And second, it allows build systems which build files elsewhere
to adapt those paths based on their own needs. This is especially nice
in the context of build systems that use out-of-tree builds like CMake
or Meson.

Remove hardcoded knowledge of build paths from our test library and move
it into our bin-wrappers and "GIT-BUILD-OPTIONS".

Subject: Introduce support for the Meson build system

Introduce support for the Meson build system, a "modern" meta build
system that supports many different platforms, including Linux, macOS,
Windows and BSDs. Meson supports different backends, including Ninja,
Xcode and Microsoft Visual Studio. Several common IDEs provide an
integration with it.

The biggest contender compared to Meson is probably CMake as outlined in
our "Documentation/technical/build-systems.txt" file. Based on my own
personal experience from working with both build systems extensively I
strongly favor Meson over CMake. In my opinion, it feels significantly
easier to use with a syntax that feels more like a "real" programming
language. The second big reason is that Meson supports Rust natively,
which may prove to be important given that the project may pick up Rust
as another language eventually.

Using Meson is rather straight-forward. An example:

    ```
    # Meson uses out-of-tree builds. You can set up multiple build
    # directories, how you name them is completely up to you.
    $ mkdir build
    $ cd build
    $ meson setup .. -Dprefix=/tmp/git-installation

    # Build the project. This also provides several other targets like
    e.g. `install` or `test`.
    $ ninja

    # Meson has been wired up to support execution of our test suites.
    # Both our unit tests and our integration tests are supported.
    # Running `meson test` without any arguments will execute all tests,
    # but the syntax supports globbing to select only some tests.
    $ meson test 't-*'
    # Execute single test interactively to allow for debugging.
    $ meson test 't0000-*' --interactive --test-args=-ix
    ```

The build instructions have been successfully tested on the following
systems, tests are passing:

  - Apple macOS 10.15.

  - FreeBSD 14.1.

  - NixOS 24.11.

  - OpenBSD 7.6.

  - Ubuntu 24.04.

  - Windows 10 with Cygwin.

  - Windows 10 with MinGW64, except for t9700, which is also broken with
    our Makefile.

  - Windows 10 with Visual Studio 2022 toolchain, using the Native Tools
    Command Prompt with `meson setup --vsenv`. Tests pass, except for
    t9700.

  - Windows 10 with Visual Studio 2022 solution, using the Native Tools
    Command Prompt with `meson setup --backend vs2022`. Tests pass,
    except for t9700.

  - Windows 10 with VS Code, using the Meson plug-in.

It is expected that there will still be rough edges in the current
version. If this patch lands the expectation is that it will coexist
with our other build systems for a while. Like this, distributions can
slowly migrate over to Meson and report any findings they have to us
such that we can continue to iterate. A potential cutoff date for other
build systems may be Git 3.0.

Some notes:

  - The installed distribution is structured somewhat differently than
    how it used to be the case. All of our binaries are installed into
    `$libexec/git-core`, while all binaries part of `$bindir` are now
    symbolic links pointing to the former. This rule is consistent in
    itself and thus easier to reason about.

  - We do not install dashed binaries into `$libexec/git-core` anymore,
    so there won't e.g. be a symlink for git-add(1). These are not
    required by modern Git and there isn't really much of a use case for
    those anymore. By not installing those symlinks we thus start the
    deprecation of this layout.

  - We're targeting Meson 1.3.0, which has been released relatively
    recently November 2023. The only feature we use from that version is
    `fs.relative_to()`, which we could replace if necessary. If so, we
    could start to target Meson 1.0.0 and newer, released in December
    2022.

  - The whole build instructions count around 3300 lines, half of which
    is listing all of our code and test files. Our Makefiles are around
    5000 lines, autoconf adds another 1300 lines. CMake in comparison
    has only 1200 linescode, but it avoids listing individual files and
    does not wire up auto-configuration as extensively as the Meson
    instructions do.

  - We bundle a set of subproject wrappers for curl, expat, openssl,
    pcre2 and zlib. This allows developers to build Git without these
    dependencies preinstalled, and Meson will fetch and build them
    automatically. This is especially helpful on Windows.

+# Meson build system
+# ==================
+#
+# The Meson build system is an alternative to our Makefile that you can use to
+# build, test and install Git. Using Meson results in a couple of benefits:
+#
+#  - Out-of-tree builds.
+#  - Better integration into IDEs.
+#  - Easy-to-use autoconfiguration of available features on your system.
+#
+# To use Meson from the command line you need to have both Meson and Ninja
+# installed. Alternatively, if you do not have Python available on your system,
+# you can also use Muon instead of Meson and Samurai instead of Ninja, both of
+# which are drop-ins replacement that only depend on C.
+#
+# Basic usage
+# ===========
+#
+# In the most trivial case, you can configure, build and install Git like this:
+#
+#  1. Set up the build directory. This only needs to happen once per build
+#     directory you want to have. You can also configure multiple different
+#     build directories with different configurations.
+#
+#      $ meson setup build/
+#
+#     The build directory gets ignored by Git automatically as Meson will write
+#     a ".gitignore" file into it. From hereon, we will assume that you execute
+#     commands inside this build directory.
+#
+# 2. Compile Git. You can either use Meson, Ninja or Samurai to do this, so all
+#    of the following invocations are equivalent:
+#
+#      $ meson compile
+#      $ ninja
+#      $ samu
+#
+#   The different invocations should ultimately not make much of a difference.
+#   Using Meson also works with other generators though, like when the build
+#   directory has been set up for use with Microsoft Visual Studio.
+#
+#   Ninja and Samurai use multiple jobs by default, scaling with the number of
+#   processor cores available. You can pass the `-jN` flag to change this.
+#
+#   Meson automatically picks up ccache and sccache when these are installed
+#   when setting up the build directory. You can override this behaviour when
+#   setting up the build directory by setting the `CC` environment variable to
+#   your desired compiler.
+#
+# 3. Execute tests. Again, you can either use Meson, Ninja or Samurai to do this:
+#
+#      $ meson test
+#      $ ninja test
+#      $ samu test
+#
+#   It is recommended to use Meson in this case though as it also provides you
+#   additional features that the other build systems don't have available.
+#   You can e.g. pass additional arguments to the test executables or run
+#   individual tests:
+#
+#      # Execute the t0000-basic integration test and t-reftable-stack unit test.
+#      $ meson test t0000-basic t-reftable-stack
+#
+#      # Execute all reftable unit tests.
+#      $ meson test t-reftable-*
+#
+#      # Execute all tests and stop with the first failure.
+#      $ meson test --maxfail 1
+#
+#      # Execute single test interactively such that features like `debug ()` work.
+#      $ meson test -i --test-args='-ix' t1400-update-ref
+#
+#   Test execution is parallelized by default and scales with the number of
+#   processor cores available. You can change the number of processes by passing
+#   the `-jN` flag to `meson test`.
+#
+# 4. Install the Git distribution. Again, this can be done via Meson, Ninja or
+#    Samurai:
+#
+#      $ meson install
+#      $ ninja install
+#      $ samu install
+#
+#    The prefix into which Git shall be installed is defined when setting up
+#    the build directory. More on that in the "Configuration" section.
+#
+# Meson supports multiple backends. The default backend generates Ninja build
+# instructions, but it also supports the generation of Microsoft Visual
+# Studio solutions as well as Xcode projects by passing the `--backend` option
+# to `meson setup`. IDEs like Eclipse and Visual Studio Code provide plugins to
+# import Meson files directly.
+#
+# Configuration
+# =============
+#
+# The exact configuration of Git is determined when setting up the build
+# directory via `meson setup`. Unless told otherwise, Meson will automatically
+# detect the availability of various bits and pieces. There are two different
+# kinds of options that can be used to further tweak the build:
+#
+#   - Built-in options provided by Meson.
+#
+#   - Options defined by the project in the "meson_options.txt" file.
+#
+# Both kinds of options can be inspected by running `meson configure` in the
+# build directory, which will give you a list of the current value for all
+# options.
+#
+# Options can be configured either when setting up the build directory or can
+# be changed in preexisting build directories:
+#
+#      # Set up a new build directory with optimized settings that will be
+#      # installed into an alternative prefix.
+#      $ meson setup --buildtype release --optimization 3 --strip --prefix=/home/$USER build
+#
+#      # Set up a new build directory with a higher warning level. Level 2 is
+#      # mostly equivalent to setting DEVELOPER=1, level 3 and "everything"
+#      # will enable even more warnings.
+#      $ meson setup -Dwarning_level=2 build
+#
+#      # Set up a new build directory with 'address' and 'undefined' sanitizers
+#      # using Clang.
+#      $ CC=clang meson setup -Db_sanitize=address,undefined build
+#
+#      # Disable tests in a preexisting build directory.
+#      $ meson configure -Dtests=false
+#
+#      # Disable features based on Python
+#      $ meson configure -Dpython=disabled
+#
+# Options have a type like booleans, choices, strings or features. Features are
+# somewhat special as they can have one of three values: enabled, disabled or
+# auto. While the first two values are self-explanatory, "auto" will enable or
+# disable the feature based on the availability of prerequisites to support it.
+# Python-based features for example will be enabled automatically when a Python
+# interpreter could be found. The default value of such features can be changed
+# via `meson setup --auto-features={enabled,disabled,auto}`, which will set the
+# value of all features with a value of "auto" to the provided one by default.
+#
+# It is also possible to store a set of configuration options in machine files.
+# This can be useful in case you regularly want to reuse the same set of options:
+#
+#   [binaries]
+#   c = ['clang']
+#   ar = ['ar']
+#
+#   [project options]
+#   gettext = 'disabled'
+#   default_editor = 'vim'
+#
+#   [built-in options]
+#   b_lto = true
+#   b_sanitize = 'address,undefined'
+#
+# These machine files can be passed to `meson setup` via the `--native-file`
+# option.
+#
+# Subproject wrappers
+# ===================
+#
+# Subproject wrappers are a feature provided by Meson that allows the automatic
+# fallback to a "wrapped" dependency in case the dependency is not provided by
+# the system. For example if the system is lacking curl, then Meson will use
+# "subprojects/curl.wrap" to set up curl as a subproject and compile and link
+# the dependency into Git itself. This is especially helpful on systems like
+# Windows, where you typically don't have such dependencies installed.
+#
+# The use of subproject wrappers can be disabled by executing `meson setup`
+# with the `--wrap-mode nofallback` option.

Subject: cmake: better support for out-of-tree builds follow-up

In 7e0730c8baa (t: better support for out-of-tree builds, 2024-12-06),
the `bin-wrappers/` strategy was changed so that it no longer hard-codes
the template directory to be `@BUILD_DIR@/templates/blt`, but instead
interpolates the `@TEMPLATE_DIR@` placeholder during the build.

However, this commit only adjusted the `Makefile`-based build.

Let's adjust the CMake-based build as well. This fixes t0000.15 which
would otherwise fail with:

  ++ echo ''\''t1234-verbose/err'\'' is not empty, it contains:'
  't1234-verbose/err' is not empty, it contains:
  ++ cat t1234-verbose/err
  warning: templates not found in @TEMPLATE_DIR@

Subject: cmake(mergetools): better support for out-of-tree builds

In 7e0730c8baa (t: better support for out-of-tree builds, 2024-12-06)
the strategy was changed from letting `t7609-mergetool--lib.sh`
hard-code the directory where it expects to find the merge tools to
hard-coding that value in the placeholder `@GIT_TEST_MERGE_TOOLS_DIR@`
that is replaced during the build.

However, likely due to a copy/paste mistake (and reviewers missed this,
too), the CMake-based build was adjusted incorrectly, replacing that
placeholder not with the path to the merge tools, but with a Boolean
indicating whether to use a runtime-generated path prefix or not.

Let's fix that, addressing this CMake-build's symptom:

  Initialized empty Git repository in D:/a/git/git/t/trash directory.t7609-mergetool--lib/.git/
  ++ . true/vimdiff
  ./test-lib.sh: line 1021: true/vimdiff: No such file or directory

Subject: cmake: use the correct file name for the Perl header

In e4b488049a5 (Makefile: extract script to massage Perl scripts,
2024-12-06), the code was refactored that is used to transform the Perl
scripts/modules to their final form.

Even the CMake-based build was adjusted, but the change used the file
name `PERL-HEADER` instead of the file name used by the Makefile-based
build (same name but with the `GIT-` prefix). Let's adjust the former to
the latter.

Subject: cmake: put the Perl modules into the correct location again

In ccfba9e0c45 (Makefile: use "generate-perl.sh" to massage Perl
library, 2024-12-06), the previous strategy (which avoided spawning a
shell script to transform the files) was replaced by the same
`generate-perl.sh` invocation as for the Makefile-based build.

The only difference is that now the transformation tries to handle the
Perl modules in-place (which ends up in empty files because the same
file is used as input and output via stdin/stdout redirection), and the
Perl script cannot find them anymore because they are not in the
expected place.

Let's put them into the expected place again, i.e. into
`perl/build/lib/` instead of `perl/`.

Subject: cmake/vcxproj: stop special-casing `remote-ext`

When the `vcxproj` target was introduced in `config.mak.uname` to allow
building Git with the Visual C toolchain, the `git remote-ext` command
was always executed in its dashed form. Therefore, it was impossible to
pass the test suite unless that command existed in its dashed form, and
we had to special-case this.

Later, when the `vcxproj` target got out of fashion because Visual
Studio gained native support for CMake builds, this special-casing was
copied without questioning it.

But as of 675df192c5f (transport-helper: do not run git-remote-ext etc.
in dashed form, 2020-08-26), the reason for this special-casing no
longer exists. So let's just drop it.

From cbcc2f79117ded0161b012dc5107f181b5d87b09 Mon Sep 17 00:00:00 2001
From: Patrick Steinhardt <ps@pks.im>
Date: Fri, 27 Dec 2024 13:10:18 +0100
Subject: GIT-BUILD-OPTIONS: wire up NO_GITWEB option

Building our "gitweb" interface is optional in our Makefile and in Meson
and not wired up at all with CMake, but disabling it causes a couple of
tests in the t950* range that pull in "t/lib-gitweb.sh". This is because
the test library knows to execute gitweb-tests based on whether or not
Perl is available, but we may have Perl available and still end up not
building gitweb e.g. with `make test NO_GITWEB=YesPlease`.

Fix this issue by wiring up a new "NO_GITWEB" build option so that we
can skip these tests in case gitweb is not built.

Note that this new build option requires us to move the configuration of
GIT-BUILD-OPTIONS to a later point in our Meson build instructions. But
as that file is only consumed by our tests at runtime this change does
not cause any issues.

Subject: completion: repair config completion for Zsh
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 1e0ee4087e (completion: add and use
__git_compute_first_level_config_vars_for_section, 2024-02-10) uses an
indirect variable syntax that is only valid for Bash, but the Zsh
completion code relies on the Bash completion code to function. Zsh
supports a different indirect variable expansion using ${(P)var}, but in
`emulate ksh` mode does not support Bash's ${!var}.

This manifests as completing strange config options like
"__git_first_level_config_vars_for_section_remote" as a choice for the
command line

    git config set remote.

Using Zsh's C-x ? _complete_debug widget with the cursor at the end of
that command line captures a trace, in which we see (some details
elided):

    +__git_complete_config_variable_name:7> __git_compute_first_level_config_vars_for_section remote
     +__git_compute_first_level_config_vars_for_section:7> local section=remote
     +__git_compute_first_level_config_vars_for_section:7> __git_compute_config_vars
      +__git_compute_config_vars:7> test -n $'add.ignoreErrors\nadvice.addEmbeddedRepo\nadvice.addEmptyPathspec\nadvice.addIgnoredFile[…]'
     +__git_compute_first_level_config_vars_for_section:7> local this_section=__git_first_level_config_vars_for_section_remote
     +__git_compute_first_level_config_vars_for_section:7> test -n __git_first_level_config_vars_for_section_remote
    +__git_complete_config_variable_name:7> local this_section=__git_first_level_config_vars_for_section_remote
    +__git_complete_config_variable_name:7> __gitcomp_nl_append __git_first_level_config_vars_for_section_remote remote. '' ' '
     +__gitcomp_nl_append:7> __gitcomp_nl __git_first_level_config_vars_for_section_remote remote. '' ' '
      +__gitcomp_nl:7> emulate -L zsh
      +__gitcomp_nl:7> compset -P '*[=:]'
      +__gitcomp_nl:7> compadd -Q -S ' ' -p remote. -- __git_first_level_config_vars_for_section_remote

We perform the test for __git_compute_config_vars correctly, but the
${!this_section} references are not expanded as expected.

Instead, portably expand indirect references through the new
__git_indirect. Contrary to some versions you might find online [1],
this version avoids echo non-portabilities [2] [3] and correctly quotes
the indirect expansion after eval (so that the result is not split or
globbed before being handed to printf).

[1]: https://unix.stackexchange.com/a/41409/301073
[2]: https://askubuntu.com/questions/715765/mysterious-behavior-of-echo-command#comment1056038_715769
[3]: https://mywiki.wooledge.org/CatEchoLs

The following demo program demonstrates how this works:

    b=1
    indirect() {
      eval printf '%s' "\"\$$1\""
    }
    f() {
      # Comment this out to see that it works for globals, too. Or, use
      # a value with spaces like '2 3 4' to see how it handles those.
      local b=2
      local a=b
      test -n "$(indirect $a)" && echo nice
    }
    f

When placed in a file "demo", then both
    bash -x demo
and
    zsh -xc 'emulate ksh -c ". ./demo"' |& tail
provide traces showing that "$(indirect $a)" produces 2 (or 1, with the
global, or "2 3 4" as a single string, etc.).

Subject: contrib/subtree: fix building docs

In a38edab7c8 (Makefile: generate doc versions via GIT-VERSION-GEN,
2024-12-06), we have refactored how we build our documentation by
injecting the Git version into the Asciidoc and AsciiDoctor config
files instead of doing so via arguments. As such, the original config
files were removed, where the expectation is that they get generated via
`GIT-VERSION-GEN` now.

Whie the git-subtree(1) command part of "contrib/" also builds docs
using these same config files, its Makefile wasn't adjusted accordingly
and thus building the docs is broken.

Fix this by using `GIT-VERSION-GEN` to generate those files.

Subject: meson: introduce build option for contrib

We unconditionally wire up building command completion present in the
"contrib/" directory. This may or may not be what users want, and we
don't provide a way to disable it.

Introduce a new "contrib" build option. This option is introduced as an
array so that users can manually pick which exact features they want to
include from the "contrib" directory. By default, we build and install
shell completions, which is a commonly used feature and also the current
default.

Wire up the git-subtree(1) command, which is part of "contrib/". Note
that we have to move around the exact location where we include the
"contrib/" subdirectory so that it comes after building the docs so that
we have access to some of the common functionality.

Subject: Makefile: wire up build option for deprecated features

With 57ec9254eb (docs: introduce document to announce breaking changes,
2024-06-14), we have introduced a new document that tracks upcoming
breaking changes in the Git project. In 2454970930 (BreakingChanges:
early adopter option, 2024-10-11) we have amended the document a bit to
mention that any introduced breaking changes must be accompanied by
logic that allows us to enable the breaking change at compile-time.
While we already have two breaking changes lined up, neither of them has
such a switch because they predate those instructions.

Introduce the proposed `WITH_BREAKING_CHANGES` preprocessor macro and
wire it up with both our Makefiles and Meson. This does not yet wire up
the build flag for existing deprecations.
