Introduce CMake support for configuring Git
At the moment, the recommended way to configure Git's builds is to
simply run `make`. If that does not work, the recommended strategy is to
look at the top of the `Makefile` to see whether any "Makefile knob" has
to be turned on/off, e.g. `make NO_OPENSSL=YesPlease`.
Alternatively, Git also has an `autoconf` setup which allows configuring
builds via `./configure [<option>...]`.
Both of these options are fine if the developer works on Unix or Linux.
But on Windows, we have to jump through hoops to configure a build
(read: we force the user to install a full Git for Windows SDK, which
occupies around two gigabytes (!) on disk and downloads about three
quarters of a gigabyte worth of Git objects).
The build infrastructure for Git is written around being able to run
make, which is not supported natively on Windows.
To help Windows developers a CMake build script is introduced here.
With a working support CMake, developers on Windows need only install
CMake, configure their build, load the generated Visual Studio solution
and immediately start modifying the code and build their own version of
Git. Likewise, developers on other platforms can use the convenient GUI
tools provided by CMake to configure their build.
So let's start building CMake support for Git.
This is only the first step, and to make it easier to review, it only
allows for configuring builds on the platform that is easiest to
configure for: Linux.
The CMake script checks whether the headers are present(eg. libgen.h),
whether the functions are present(eg. memmem), whether the funtions work
properly (eg. snprintf) and generate the required compile definitions
for the platform. The script also searches for the required libraries,
if it fails to find the required libraries the respective executables
won't be built.(eg. If libcurl is not found then git-remote-http won't
be built). This will help building Git easier.
With a CMake script an out of source build of git is possible resulting
in a clean source tree.
Note: this patch asks for the minimum version v3.14 of CMake (which is
not all that old as of time of writing) because that is the first
version to offer a platform-independent way to generate hardlinks as
part of the build. This is needed to generate all those hardlinks for
the built-in commands of Git.

Open the worktree as a folder. Visual Studio 2019 and later will detect
|
|
|
|
the CMake configuration automatically and set everything up for you,
|
|
|
|
ready to build. You can then run the tests in `t/` via a regular Git Bash.

mkdir -p contrib/buildsystems/out

this option is ignored

NOTE: By default CMake uses Makefile as the build tool on Linux and Visual Studio in Windows,

#macros for parsing the Makefile for sources and scripts
|
Introduce CMake support for configuring Git
At the moment, the recommended way to configure Git's builds is to
simply run `make`. If that does not work, the recommended strategy is to
look at the top of the `Makefile` to see whether any "Makefile knob" has
to be turned on/off, e.g. `make NO_OPENSSL=YesPlease`.
Alternatively, Git also has an `autoconf` setup which allows configuring
builds via `./configure [<option>...]`.
Both of these options are fine if the developer works on Unix or Linux.
But on Windows, we have to jump through hoops to configure a build
(read: we force the user to install a full Git for Windows SDK, which
occupies around two gigabytes (!) on disk and downloads about three
quarters of a gigabyte worth of Git objects).
The build infrastructure for Git is written around being able to run
make, which is not supported natively on Windows.
To help Windows developers a CMake build script is introduced here.
With a working support CMake, developers on Windows need only install
CMake, configure their build, load the generated Visual Studio solution
and immediately start modifying the code and build their own version of
Git. Likewise, developers on other platforms can use the convenient GUI
tools provided by CMake to configure their build.
So let's start building CMake support for Git.
This is only the first step, and to make it easier to review, it only
allows for configuring builds on the platform that is easiest to
configure for: Linux.
The CMake script checks whether the headers are present(eg. libgen.h),
whether the functions are present(eg. memmem), whether the funtions work
properly (eg. snprintf) and generate the required compile definitions
for the platform. The script also searches for the required libraries,
if it fails to find the required libraries the respective executables
won't be built.(eg. If libcurl is not found then git-remote-http won't
be built). This will help building Git easier.
With a CMake script an out of source build of git is possible resulting
in a clean source tree.
Note: this patch asks for the minimum version v3.14 of CMake (which is
not all that old as of time of writing) because that is the first
version to offer a platform-independent way to generate hardlinks as
part of the build. This is needed to generate all those hardlinks for

Introduce CMake support for configuring Git
At the moment, the recommended way to configure Git's builds is to
simply run `make`. If that does not work, the recommended strategy is to
look at the top of the `Makefile` to see whether any "Makefile knob" has
to be turned on/off, e.g. `make NO_OPENSSL=YesPlease`.
Alternatively, Git also has an `autoconf` setup which allows configuring
builds via `./configure [<option>...]`.
Both of these options are fine if the developer works on Unix or Linux.
But on Windows, we have to jump through hoops to configure a build
(read: we force the user to install a full Git for Windows SDK, which
occupies around two gigabytes (!) on disk and downloads about three
quarters of a gigabyte worth of Git objects).
The build infrastructure for Git is written around being able to run
make, which is not supported natively on Windows.
To help Windows developers a CMake build script is introduced here.
With a working support CMake, developers on Windows need only install
CMake, configure their build, load the generated Visual Studio solution
and immediately start modifying the code and build their own version of
Git. Likewise, developers on other platforms can use the convenient GUI
tools provided by CMake to configure their build.
So let's start building CMake support for Git.
This is only the first step, and to make it easier to review, it only
allows for configuring builds on the platform that is easiest to
configure for: Linux.
The CMake script checks whether the headers are present(eg. libgen.h),
whether the functions are present(eg. memmem), whether the funtions work
properly (eg. snprintf) and generate the required compile definitions
for the platform. The script also searches for the required libraries,
if it fails to find the required libraries the respective executables
won't be built.(eg. If libcurl is not found then git-remote-http won't
be built). This will help building Git easier.
With a CMake script an out of source build of git is possible resulting
in a clean source tree.
Note: this patch asks for the minimum version v3.14 of CMake (which is
not all that old as of time of writing) because that is the first
version to offer a platform-independent way to generate hardlinks as
part of the build. This is needed to generate all those hardlinks for
the built-in commands of Git.

drop vcs-svn experiment
The code in vcs-svn was started in 2010 as an attempt to build a
remote-helper for interacting with svn repositories (as opposed to
git-svn). However, we never got as far as shipping a mature remote
helper, and the last substantive commit was e99d012a6bc in 2012.
We do have a git-remote-testsvn, and it is even installed as part of
"make install". But given the name, it seems unlikely to be used by
anybody (you'd have to explicitly "git clone testsvn::$url", and there
have been zero mentions of that on the mailing list since 2013, and even
that includes the phrase "you might need to hack a bit to get it working
properly"[1]).
We also ship contrib/svn-fe, which builds on the vcs-svn work. However,
it does not seem to build out of the box for me, as the link step misses
some required libraries for using libgit.a. Curiously, the original
build breakage bisects for me to eff80a9fd9 (Allow custom "comment
char", 2013-01-16), which seems unrelated. There was an attempt to fix
it in da011cb0e7 (contrib/svn-fe: fix Makefile, 2014-08-28), but on my
system that only switches the error message.
So it seems like the result is not really usable by anybody in practice.
It would be wonderful if somebody wanted to pick up the topic again, and
potentially it's worth carrying around for that reason. But the flip
side is that people doing tree-wide operations have to deal with this
code. And you can see the list with (replace "HEAD" with this commit as
appropriate):
{
echo "--"
git diff-tree --diff-filter=D -r --name-only HEAD^ HEAD
} |
git log --no-merges --oneline e99d012a6bc.. --stdin
which shows 58 times somebody had to deal with the code, generally due
to a compile or test failure, or a tree-wide style fix or API change.
Let's drop it and let anybody who wants to pick it up do so by
resurrecting it from the git history.
As a bonus, this also reduces the size of a stripped installation of Git
from 21MB to 19MB.

Introduce CMake support for configuring Git
At the moment, the recommended way to configure Git's builds is to
simply run `make`. If that does not work, the recommended strategy is to
look at the top of the `Makefile` to see whether any "Makefile knob" has
to be turned on/off, e.g. `make NO_OPENSSL=YesPlease`.
Alternatively, Git also has an `autoconf` setup which allows configuring
builds via `./configure [<option>...]`.
Both of these options are fine if the developer works on Unix or Linux.
But on Windows, we have to jump through hoops to configure a build
(read: we force the user to install a full Git for Windows SDK, which
occupies around two gigabytes (!) on disk and downloads about three
quarters of a gigabyte worth of Git objects).
The build infrastructure for Git is written around being able to run
make, which is not supported natively on Windows.
To help Windows developers a CMake build script is introduced here.
With a working support CMake, developers on Windows need only install
CMake, configure their build, load the generated Visual Studio solution
and immediately start modifying the code and build their own version of
Git. Likewise, developers on other platforms can use the convenient GUI
tools provided by CMake to configure their build.
So let's start building CMake support for Git.
This is only the first step, and to make it easier to review, it only
allows for configuring builds on the platform that is easiest to
configure for: Linux.
The CMake script checks whether the headers are present(eg. libgen.h),
whether the functions are present(eg. memmem), whether the funtions work
properly (eg. snprintf) and generate the required compile definitions
for the platform. The script also searches for the required libraries,
if it fails to find the required libraries the respective executables
won't be built.(eg. If libcurl is not found then git-remote-http won't
be built). This will help building Git easier.
With a CMake script an out of source build of git is possible resulting
in a clean source tree.
Note: this patch asks for the minimum version v3.14 of CMake (which is
not all that old as of time of writing) because that is the first
version to offer a platform-independent way to generate hardlinks as
part of the build. This is needed to generate all those hardlinks for
the built-in commands of Git.

Introduce CMake support for configuring Git
At the moment, the recommended way to configure Git's builds is to
simply run `make`. If that does not work, the recommended strategy is to
look at the top of the `Makefile` to see whether any "Makefile knob" has
to be turned on/off, e.g. `make NO_OPENSSL=YesPlease`.
Alternatively, Git also has an `autoconf` setup which allows configuring
builds via `./configure [<option>...]`.
Both of these options are fine if the developer works on Unix or Linux.
But on Windows, we have to jump through hoops to configure a build
(read: we force the user to install a full Git for Windows SDK, which
occupies around two gigabytes (!) on disk and downloads about three
quarters of a gigabyte worth of Git objects).
The build infrastructure for Git is written around being able to run
make, which is not supported natively on Windows.
To help Windows developers a CMake build script is introduced here.
With a working support CMake, developers on Windows need only install
CMake, configure their build, load the generated Visual Studio solution
and immediately start modifying the code and build their own version of
Git. Likewise, developers on other platforms can use the convenient GUI
tools provided by CMake to configure their build.
So let's start building CMake support for Git.
This is only the first step, and to make it easier to review, it only
allows for configuring builds on the platform that is easiest to
configure for: Linux.
The CMake script checks whether the headers are present(eg. libgen.h),
whether the functions are present(eg. memmem), whether the funtions work
properly (eg. snprintf) and generate the required compile definitions
for the platform. The script also searches for the required libraries,
if it fails to find the required libraries the respective executables
won't be built.(eg. If libcurl is not found then git-remote-http won't
be built). This will help building Git easier.
With a CMake script an out of source build of git is possible resulting
in a clean source tree.
Note: this patch asks for the minimum version v3.14 of CMake (which is
not all that old as of time of writing) because that is the first
version to offer a platform-independent way to generate hardlinks as
part of the build. This is needed to generate all those hardlinks for
the built-in commands of Git.

drop vcs-svn experiment
The code in vcs-svn was started in 2010 as an attempt to build a
remote-helper for interacting with svn repositories (as opposed to
git-svn). However, we never got as far as shipping a mature remote
helper, and the last substantive commit was e99d012a6bc in 2012.
We do have a git-remote-testsvn, and it is even installed as part of
"make install". But given the name, it seems unlikely to be used by
anybody (you'd have to explicitly "git clone testsvn::$url", and there
have been zero mentions of that on the mailing list since 2013, and even
that includes the phrase "you might need to hack a bit to get it working
properly"[1]).
We also ship contrib/svn-fe, which builds on the vcs-svn work. However,
it does not seem to build out of the box for me, as the link step misses
some required libraries for using libgit.a. Curiously, the original
build breakage bisects for me to eff80a9fd9 (Allow custom "comment
char", 2013-01-16), which seems unrelated. There was an attempt to fix
it in da011cb0e7 (contrib/svn-fe: fix Makefile, 2014-08-28), but on my
system that only switches the error message.
So it seems like the result is not really usable by anybody in practice.
It would be wonderful if somebody wanted to pick up the topic again, and
potentially it's worth carrying around for that reason. But the flip
side is that people doing tree-wide operations have to deal with this
code. And you can see the list with (replace "HEAD" with this commit as
appropriate):
{
echo "--"
git diff-tree --diff-filter=D -r --name-only HEAD^ HEAD
} |
git log --no-merges --oneline e99d012a6bc.. --stdin
which shows 58 times somebody had to deal with the code, generally due
to a compile or test failure, or a tree-wide style fix or API change.
Let's drop it and let anybody who wants to pick it up do so by
resurrecting it from the git history.
As a bonus, this also reduces the size of a stripped installation of Git
from 21MB to 19MB.
