# dotnet8-runtime
This is the .NET 8.0 package for Alpine Linux.
Please report any issues [using Gitlab](https://gitlab.alpinelinux.org/alpine/aports/-/issues/new) and tag @ayakael
# Building info
## Generated packages
* `aspnetcore8-runtime`
* `aspnetcore8-targeting-pack`
* `dotnet8-apphost-pack` (used by dotnet8-runtime)
* `dotnet8-hostfxr` (used by dotnet-host)
* `dotnet8-runtime`
* `dotnet8-targeting-pack`
* `dotnet-host`
## How to build dotnet8 on Alpine
As dotnet is a self-hosting compiler (thus it compiles using itself), it
requires a bootstrap for the initial build. To solve this problem, this package
follows the `stage0` proposal outlined [here](https://lists.alpinelinux.org/~alpine/devel/%3C33KG0XO61I4IL.2Z7RTAZ5J3SY6%408pit.net%3E)
The goal of `stage0` is to bootstrap dotnet with as little intervention as
possible, thus allowing seamless Alpine upgrades. Unfortunately, upstream only
builds bootstraps for Alpine on `x86_64`, `aarch64`, and `armv7`. Thus, `stage0`
has also been designed to be crossbuild aware, allowing bootstrapping to other
platforms.
In summary, dotnet8 is built using three different aports.
* `community/dotnet8-stage0`
Builds minimum components for full build of dotnet8, and packages these in an initial
`dotnet8-stage0-bootstrap` package that `dotnet8-build` pulls.
* `community/dotnet8-build`
Builds full and packages dotnet8 fully using either stage0 or previoulsy built
dotnet8 build.
* `community/dotnet8-runtime`
As abuild does not allow different versions for subpackages, a different aport
is required to package runtime bits from dotnet8-build.
## Crossbuilding with `stage0`
Crossbuilding `stage0` is a three step process:
1. Build sysroot for target platform by using `scripts/bootstrap.sh` in aports repo:
```
./bootstrap.sh $CTARGET_ARCH
```
2. Although not necessary, it is recommended to add Alpine repositories to
`$HOME/sysroot-$CTARGET_ARCH/etc/apk/repositories`, making sure to add required
keys. This makes it so that whatever package is not built in step 1 will
be pulled from package repos
3. Crossbuild `dotnet8-stage0` via:
```
CHOST=$CTARGET_ARCH abuild -r
```
# Specification
This package follows [package naming and contents suggested by upstream](https://docs.microsoft.com/en-us/dotnet/core/build/distribution-packaging),
with two exceptions. It installs dotnet to `/usr/lib/dotnet` (aka `$_libdir`).
In addition, the package is named `dotnet8` as opposed to `dotnet-8.0`
to match Alpine Linux naming conventions for packages with many installable versions
# Contributing
The steps below are for the final package. Please only contribute to a
pre-release version if you know what you are doing. Original instructions
follow.
## General Changes
1. Fork the main aports repo.
2. Checkout the forked repository.
- `git clone ssh://git@gitlab.alpinelinux.org/$USER/aports`
- `cd community/dotnet8-build`
3. Make your changes. Don't forget to add a changelog.
4. Do local builds.
- `abuild -r`
5. Fix any errors that come up and rebuild until it works locally.
6. Commit the changes to the git repo in a git branch
- `git checkout -b dotnet8/<name>`
- `git add` any new patches
- `git remove` any now-unnecessary patches
- `git commit -m 'community/dotnet8-build: descriptive description'`
- `git push`
7. Create a merge request with your changes, tagging @ayakael for review.
8. Once the tests in the pull-request pass, and reviewers are happy, your changes
will be merged.
## Updating to an new upstream release
1. Fork the main aports repo.
2. Checkout the forked repository.
- `git clone ssh://git@gitlab.alpinelinux.org/$USER/aports`
- `cd community/dotnet8-build`
3. Build the new upstream source tarball. Update the versions in the
APKBUILD file, and then create a snapshot. After build, update checksum.
- `abuild snapshot`
- `abuild checksum`
4. Do local builds.
- `abuild -r`
5. Fix any errors that come up and rebuild until it works locally. Any
patches that are needed at this point should be added to the APKBUILD file
in `_patches` variable.
6. Upload the source archive to a remote location, and update `source` variable.
7. Commit the changes to the git repo in a git branch.
- `git checkout -b dotnet8/<name>`
- `git add` any new patches
- `git remove` any now-unnecessary patches
- `git commit -m 'community/dotnet8-build: upgrade to <new-version>`
- `git push`
8. Create a merge request with your changes, tagging @ayakael for review.
9. Once the tests in the pull-request pass, and reviewers are happy, your changes
will be merged.
# Testing
This package uses CI tests as defined in `check()` function. Creating a
merge-request or running a build will fire off tests and flag any issues.
The tests themselves are contained in this external repository:
