This directory contains scripts and files to package libsodium for .NET Core.
|
|
|
|
*Note:* The NuGet package is intended for the implementation of language
|
|
bindings such as [NSec](https://github.com/ektrah/nsec). It does not provide a
|
|
.NET API itself.
|
|
|
|
In .NET Core, it is customary to provide pre-compiled binaries for all platforms
|
|
as NuGet packages. The purpose of the `prepare.py` script in this directory is
|
|
to generate a `Makefile` that downloads and builds libsodium binaries for a
|
|
number of platforms and assembles them in a NuGet package that can be uploaded
|
|
to [nuget.org](https://nuget.org/).
|
|
|
|
* For Windows, binaries are obtained from
|
|
[download.libsodium.org](https://download.libsodium.org/libsodium/releases/).
|
|
* For macOS, binaries are extracted from the
|
|
[Homebrew libsodium bottle](https://bintray.com/homebrew/bottles/libsodium).
|
|
* For Linux, libsodium is compiled in Docker containers.
|
|
|
|
See `prepare.py` for the complete list of supported platforms.
|
|
|
|
The metadata for the NuGet package is located in `libsodium.props`.
|
|
|
|
|
|
**Versioning**
|
|
|
|
Version numbers for the packages for .NET Core consist of three components:
|
|
|
|
* *libsodium version*
|
|
The libsodium version is in the format `X.Y.Z`.
|
|
* *package revision*
|
|
It may be necessary to release more than one package for a libsodium version,
|
|
e.g., when adding support for a new platform or if a release contains a broken
|
|
binary. In this case, a package revision number is added as a fourth part to
|
|
the libsodium version, starting at `1`. For example, `1.0.14` is the initial
|
|
release of the package for libsodium 1.0.14 and `1.0.14.5` is the fifth
|
|
revision (sixth release) of that package.
|
|
* *pre-release label*
|
|
If a package is a pre-release, a label is appended to the version number in
|
|
`-preview-##` format where `##` is the number of the pre-release, starting at
|
|
`01`. For example, `1.0.14-preview-01` is the first pre-release of the package
|
|
for libsodium 1.0.14 and `1.0.14.5-preview-02` the second pre-release of the
|
|
fifth revision of the package for libsodium 1.0.14.
|
|
|
|
|
|
**Making a release**
|
|
|
|
1. Update any existing Docker images.
|
|
2. Run `python3 prepare.py <version>` to generate the `Makefile`, where
|
|
`<version>` is the package version number in the format described above.
|
|
3. Take a look at the generated `Makefile`. It uses `sudo` a few times.
|
|
4. Run `make` to download and build the binaries and create the NuGet package.
|
|
You may need to install `docker`, `make`, `curl`, `tar` and `unzip` first.
|
|
5. Grab a cup of coffee. Downloading the Docker images and compiling the Linux
|
|
binaries takes a while. When done, the NuGet package is output as a `.nupkg`
|
|
file in the `build` directory.
|
|
6. Run `make test` to perform a quick test of the NuGet package. Verify that
|
|
everything else in the `.nupkg` file is in place.
|
|
7. Publish the release by uploading the `.nupkg` file to
|
|
[nuget.org](https://nuget.org/).
