feat!: Rewrite build system and third-party dependencies (#1310) 

This work was done over ~80 individual commits in the `cmake` branch,
which are now being merged back into `main`. As a roll-up commit, it is
too big to be reviewable, but each change was reviewed individually in
context of the `cmake` branch. After this, the `cmake` branch will be
renamed `cmake-porting-history` and preserved.

# GitHub Actions CI
## Actions
- `custom-actions/lint-packager`:
Lints Shaka Packager. You must pass `fetch-depth: 2` to `actions/checkout`
in order to provide enough history for the linter to tell which files have
changed.
- `custom-actions/build-packager`:
Builds Shaka Packager. Leaves build artifacts in the "artifacts" folder.
Requires OS-dependent and build-dependent inputs.
- `custom-actions/test-packager`:
Tests Shaka Packager. Requires OS-dependent and build-dependent inputs.
- `custom-actions/build-docs`:
Builds Shaka Packager docs.
## Reusable workflows
- `build.yaml`:
Build and test all combinations of OS & build settings. Also builds docs on
Linux.
## Workflows
- On PR:
- `build_and_test.yaml`:
Builds and tests all combinations of OS & build settings. Also builds
docs.
- On release tag:
- `github_release.yaml`:
Creates a draft release on GitHub, builds and tests all combinations of OS
& build settings, builds docs on all OSes, attaches static release binaries
to the draft release, then fully publishes the release.
- On release published:
- `docker_hub_release.yaml`:
Builds a Docker image to match the published GitHub release, then pushes it
to Docker Hub.
- `npm_release.yaml`:
Builds an NPM package to match the published GitHub release, then pushes it
to NPM.
- `update_docs.yaml`:
Builds updated docs and pushes them to the gh-pages branch.
- `build-docs.yaml`:
Build Packager docs. Runs only on Linux.
- `build-docker.yaml`:
Build the official Docker image.
- `lint.yaml`:
Lint Shaka Packager.
- `publish-docs.yaml`:
Publish Packager docs. Runs on the latest release.
- `publish-docker.yaml`:
Publish the official docker image. Runs on all releases.
- `publish-npm.yaml`:
Publish binaries to NPM. Runs on all releases.
- `test-linux-distros.yaml`:
Test the build on all Linux distros via docker.
## Composed workflows
- On PR (`pr.yaml`), invoke:
- `lint.yaml`
- `build.yaml`
- `build-docs.yaml`
- `build-docker.yaml`
- `test-linux-distros.yaml`
## Release workflow
- `release-please.yaml`
- Updates changelogs, version numbers based on conventional commits syntax
and semantic versioning
- https://conventionalcommits.org/
- https://semver.org/
- Generates/updates a PR on each push
- When the PR is merged, runs additional steps:
- Creates a GitHub release
- Invokes `publish-docs.yaml` to publish the docs
- Invokes `publish-docker.yaml` to publish the docker image
- Invokes `build.yaml`
- Attaches the binaries from `build.yaml` to the GitHub release
- Invokes `publish-npm.yaml` to publish the binaries to NPM
## Common workflows from shaka-project
- `sync-labels.yaml`
- `update-issues.yaml`
- `validate-pr-title.yaml`
## Required Repo Secrets
- `RELEASE_PLEASE_TOKEN`: A PAT for `shaka-bot` to run the `release-please`
action. If missing, the release workflow will use the default
`GITHUB_TOKEN`
- `DOCKERHUB_CI_USERNAME`: The username of the Docker Hub CI account
- `DOCKERHUB_CI_TOKEN`: An access token for Docker Hub
- To generate, visit https://hub.docker.com/settings/security
@ -47,3 +71,12 @@
- `NPM_PACKAGE_NAME`: Not a true "secret", but stored here to avoid someone
pushing bogus packages to NPM during CI testing from a fork
- In a fork, set to a private name which differs from the production one
## Repo Settings
Each of these workflow features can be enabled by creating a "GitHub
Environment" with the same name in your repo settings. Forks will not have
these enabled by default.
- `debug`: enable debugging via SSH after a failure
- `self_hosted`: enable self-hosted runners in the build matrix

# Linux Profiling
Profiling code is enabled when the `use_allocator` variable in gyp is set to
`tcmalloc` and `profiling` variable in gyp is set to `1`. That will build the
tcmalloc library, including the cpu profiling and heap profiling code into
shaka-packager, e.g.
In theory we should be able to build packager using
[gperftools](https://github.com/gperftools/gperftools/tree/master) to
get back the profiling functionality described below. However actually
integrating this into the CMake build is not yet done. Pull requests
welcome. See https://github.com/shaka-project/shaka-packager/issues/1277
GYP_DEFINES='profiling=1 use_allocator="tcmalloc"' gclient runhooks
If the stack traces in your profiles are incomplete, this may be due to missing
frame pointers in some of the libraries. A workaround is to use the
`linux_keep_shadow_stacks=1` gyp option. This will keep a shadow stack using the
`-finstrument-functions` option of gcc and consult the stack when unwinding.
If packager was linked using `-ltcmalloc` then the following
instructions should work:

* Visual Studio 2015 Update 3, 2017, or 2019. (See below.)
* Windows 7 or newer.
* Visual Studio 2017 or newer.
* Windows 10 or newer.
Install Visual Studio 2015 Update 3 or later - Community Edition should work if
its license is appropriate for you. Use the Custom Install option and select:
Recommended version of Visual Studio is 2022, the Community edition
should work for open source development of tools like Shaka Packager
but please check the Community license terms for your specific
situation.
- Visual C++, which will select three sub-categories including MFC
- Universal Windows Apps Development Tools > Tools (1.4.1) and Windows 10 SDK
(10.0.14393)
Install the "Desktop development with C++" workload which will install
CMake and other needed tools.
If using VS 2017 or VS 2019, you must set the following environment variables,
with versions and paths adjusted to match your actual system:
If you use chocolatey, you can install these dependencies with:
```shell
GYP_MSVS_VERSION="2019"
GYP_MSVS_OVERRIDE_PATH="C:/Program Files (x86)/Microsoft Visual Studio/2019/Community"
```ps1
choco install -y `

-Path "$pythonpath/python3.exe" -Target "$pythonpath/python.exe"
# Update global PATH
$env:PATH += ";C:\Program Files\Git\bin;c:\Program Files\CMake\bin;$pythonpath"
setx PATH "$env:PATH"
```
## Install `depot_tools`
Clone a particular branch of the `depot_tools` repository from Chromium:
```shell
git clone -b chrome/4147 https://chromium.googlesource.com/chromium/tools/depot_tools.git
touch depot_tools/.disable_auto_update
```
The latest version of depot_tools will not work, so please use that branch!
### Linux and Mac
Add `depot_tools` to the end of your PATH (you will probably want to put this
in your `~/.bashrc` or `~/.zshrc`). Assuming you cloned `depot_tools` to
`/path/to/depot_tools`:
```shell
export PATH="$PATH:/path/to/depot_tools"
```
### Windows
Add depot_tools to the start of your PATH (must be ahead of any installs of
Python). Assuming you cloned the repo to C:\src\depot_tools, open:
Control Panel → System and Security → System → Advanced system settings
If you have Administrator access, Modify the PATH system variable and
put `C:\src\depot_tools` at the front (or at least in front of any directory
that might already have a copy of Python or Git).
If you don't have Administrator access, you can add a user-level PATH
environment variable and put `C:\src\depot_tools` at the front, but
if your system PATH has a Python in it, you will be out of luck.
From a cmd.exe shell, run the command gclient (without arguments). On first
run, gclient will install all the Windows-specific bits needed to work with
the code, including msysgit and python.
* If you run gclient from a non-cmd shell (e.g., cygwin, PowerShell),
it may appear to run properly, but msysgit, python, and other tools
may not get installed correctly.
* If you see strange errors with the file system on the first run of gclient,
you may want to
[disable Windows Indexing](http://tortoisesvn.tigris.org/faq.html#cantmove2).
## Get the code
Create a `shaka_packager` directory for the checkout and change to it (you can
call this whatever you like and put it wherever you like, as long as the full
path has no spaces):
Dependencies are now managed via git submodules. To get a complete
checkout you can run:
```shell
mkdir shaka_packager && cd shaka_packager
```
Run the `gclient` tool from `depot_tools` to check out the code and its
dependencies.
```shell
gclient config https://github.com/shaka-project/shaka-packager.git --name=src --unmanaged
gclient sync -r main
```
To sync to a particular commit or version, add the '-r \<revision\>' flag to
`gclient sync`, e.g.
```shell
gclient sync -r 4cb5326355e1559d60b46167740e04624d0d2f51
```
```shell
gclient sync -r v1.2.0
```
If you don't want the full repo history, you can save some time by adding the
`--no-history` flag to `gclient sync`.
When the above commands completes, it will have created a hidden `.gclient` file
and a directory called `src` in the working directory. The remaining
instructions assume you have switched to the `src` directory:
```shell
cd src
git clone --recurse-submodules https://github.com/shaka-project/shaka-packager.git
```
### Build Shaka Packager
#### Linux and Mac
Shaka Packager uses [Ninja](https://ninja-build.org) as its main build tool,
which is bundled in depot_tools.
Shaka Packager uses [CMake](https://cmake.org) as the main build tool,
with Ninja as the recommended generator (outside of Windows).
To build the code, run `ninja` command:
```shell
ninja -C out/Release
cmake -B build -G Ninja -DCMAKE_BUILD_TYPE=Release
```
If you want to build debug code, replace `Release` above with `Debug`.
We also provide a mechanism to change build settings, for example,
you can change build system to `make` by overriding `GYP_GENERATORS`:
You can change other build settings with `-D` flags to CMake, for example
you can build a shared `libpackager` instead of static by adding
```shell
GYP_GENERATORS='make' gclient runhooks
-DBUILD_SHARED_LIBS="ON"
```
After configuring CMake you can run the build with
```shell
cmake --build build --parallel
```
#### Windows
The instructions are similar, except that Windows allows using either `/` or `\`
as path separator:
Windows build instructions are similar. Using Tools > Command Line >
Developer Command Prompt should open a terminal with cmake and ctest in the
PATH. Omit the `-G Ninja` to use the default backend, and pass `--config`
during build to select the desired configuration from Visual Studio.
```shell
ninja -C out/Release
ninja -C out\Release
```
Also, unlike Linux / Mac, 32-bit is chosen by default even if the system is
64-bit. 64-bit has to be enabled explicitly and the output directory is
configured to `out/%CONFIGURATION%_x64`, i.e.:
```shell
SET GYP_DEFINES='target_arch=x64'
gclient runhooks
ninja -C out/Release_x64
cmake -B build
cmake --build build --parallel --config Release
```
### Build artifacts
After a successful build, you can find build artifacts including the main
`packager` binary in build output directory (`out/Release` or `out/Release_x64`
for release build).
`packager` binary in build output directory (`build/packager/` for a Ninja
build, `build/packager/Release/` for a Visual Studio release build, or
`build/packager/Debug/` for a Visual Studio debug build).
See [Shaka Packager Documentation](https://shaka-project.github.io/shaka-packager/html/)
on how to use `Shaka Packager`.
### Installation
To install Shaka Packager, run:
```shell
cmake --install build/ --strip --config Release
```
You can customize the output location with `--prefix` (default `/usr/local` on
Linux and macOS) and the `DESTDIR` environment variable. These are provided by
CMake and follow standard conventions for installation. For example, to build
a package by installing to `foo` instead of the system root, and to use `/usr`
instead of `/usr/local`, you could run:
```shell
DESTDIR=foo cmake --install build/ --strip --config Release --prefix=/usr
```
### Update your checkout
To update an existing checkout, you can run
```shell
git pull origin main --rebase
gclient sync
git submodule update --init --recursive
```
The first command updates the primary Packager source repository and rebases on
top of tip-of-tree (aka the Git branch `origin/main`). You can also use other
common Git commands to update the repo.
The second command syncs dependencies to the appropriate versions and re-runs
hooks as needed.
## Cross compiling for ARM on Ubuntu host
The install-build-deps script can be used to install all the compiler
and library dependencies directly from Ubuntu:
```shell
./packager/build/install-build-deps.sh
```
Install sysroot image and others using `gclient`:
```shell
GYP_CROSSCOMPILE=1 GYP_DEFINES="target_arch=arm" gclient runhooks
```
The build command is the same as in Ubuntu:
```shell
ninja -C out/Release
```
The second updates submodules for third-party dependencies.
## Notes for other linux distros

date commands for installing dependencies. For example:

Alpine uses musl which does not have mallinfo defined in malloc.h. It is

You should install `clang-format` (using `apt install` or `brew
install` depending on platform) to ensure that all code changes are
properly formatted.
You should commit or stage (with `git add`) any code changes first. Then run
