[mono-runtimes] Update @(MonoFacadeAssembly)
Fixes: dotnet#1879 Add the following Facade assemblies to `@(MonoFacadeAssembly)`: * `System.Buffers.dll` * `System.Memory.dll` * `System.Net.Http.Rtc.dll` * `System.Threading.Tasks.Extensions.dll` Note: list was reordered to be sorted as per **sort**(1), and generated with the following shell code on macOS: $ cd external/mono/mcs/class/Facades $ for d in `find . -depth 1 -type d | grep -v 'netstandard\|System.Drawing.Primitives\|System.Net.Http.Rtc' | sort -f` ; do n=`basename "$d"`; echo " <MonoFacadeAssembly Include=\"$n.dll\" />"; done | pbcopy The `netstandard` and `System.Drawing.Primitives` directory are excluded so that the comment and following `@(MonoFacadeAssembly)` entries in `ProfileAssemblies.projitems` are still relevant.

| # How To Bump Mono | ||
|
|
||
| There will eventually be two ways that xamarin-android depends on mono: | ||
|
|
||
| 1. Via [source code](#mono-source), or | ||
| 2. Via [mono archive](#mono-archive) | ||
|
|
||
|
|
||
| <a name="mono-source" /> | ||
|
|
||
| ## Mono Source | ||
|
|
||
| When using mono from source -- which is required for all versions of mono | ||
| before the `mono/2018-10` release branch -- the | ||
| [`external/mono`](../../external) git submodule reference is used. | ||
|
|
||
| Currently, many parts of the xamarin-android build system *require* the | ||
| presence and use of mono source code, including: | ||
|
|
||
| * The [`src/Mono.Posix`](../../src/Mono.Posix) and | ||
| [`src/Mono.Data.Sqlite`](../../src/Mono.Data.Sqlite) builds. | ||
| * Inclusion of PDB2MDB source code within | ||
| [`src/Xamarin.Android.Build.Tasks`](../../src/Xamarin.Android.Build.Tasks). | ||
| * Inclusion of networking and related code into | ||
| [`src/monodroid`](../../src/monodroid). | ||
|
|
||
| We are working to remove these source dependencies so that we can support using | ||
| a [Mono Archive](#mono-archive) in the future. | ||
|
|
||
| Until a Mono Archive *exists* and can be *used*, source code integration must | ||
| fulfill the following checklist: | ||
|
|
||
| - [ ] [Update `.gitmodules`](#update-gitmodules). | ||
| - [ ] [Update `external/mono` submodule reference](#update-mono-submodule). | ||
| - [ ] [Update system mono used for the build](#update-system-mono). | ||
| - [ ] [Update `MonoAndroid` Profile Assemblies](#update-profile) | ||
| - [ ] [Ensure it *builds*](#build). | ||
| - [ ] [Ensure unit tests *pass*](#unit-tests). | ||
| - [ ] [Check for API Breakage](#api-validation). | ||
| - [ ] [Create a Pull Request](#create-pr). | ||
| - [ ] [Ask for QA Validation](#qa-validation) (***LAST***). | ||
|

|
|
||
| ### Update `.gitmodules` | ||
|
|
||
| Update [`.gitmodules`](../../.gitmodules) to refer to the correct mono branch. | ||
|
|
||
|
|
||
| <a name="update-mono-submodule" /> | ||
|
|
||
| ### Update `external/mono` | ||
|
|
||
| Update the git submodule reference that [`external/mono`](../../external) refers to: | ||
|
|
||
| cd external/mono | ||
| git checkout BRANCH-NAME | ||
| git pull --rebase | ||
|
|
||
|
|
||
| <a name="update-system-mono" /> | ||
|
|
||
| ### Update system mono | ||
|
|
||
| The `$(MonoRequiredMinimumVersion)` and `$(MonoRequiredMaximumVersion)` values | ||
| within [`Configuration.props`](../../Configuration.props) | ||
| should be updated to correspond to the version number used in the mono submodule. | ||
|
|
||
| These version numbers can be found in | ||
| [mono's `configure.ac`](https://github.com/mono/mono/blob/master/configure.ac) | ||
| in the `AC_INIT()` statement. | ||
|
|
||
| The `$(_DarwinMonoFramework)` and `%(RequiredProgram.DarwinMinimumUrl)` values | ||
| within [`build-tools/dependencies/dependencies.projitems`](../../build-tools/dependencies/dependencies.projitems) | ||
| should be updated to corresponds to the version number used in the mono submodule. | ||
|
|
||
| `%(DarwinMinimumUrl)` must be a macOS `.pkg` file and must exist. | ||
|
|
||
| For example, see commit | ||
| [606675b5](https://github.com/xamarin/xamarin-android/commit/606675b59f52595e3030c529de4c856fb347edd8): | ||

| ### Update `MonoAndroid` Profile Assemblies | ||
|
|
||
| [`src/mono-runtimes/ProfileAssemblies.projitems`](../../src/mono-runtimes/ProfileAssemblies.projitems) | ||
| has three item groups that may need to be updated: | ||
|
|
||
| * `@(MonoFacadeAssembly)` | ||
| * `@(MonoProfileAssembly)` | ||
| * `@(MonoTestAssembly)` | ||
|
|
||
| There must be a `@(MonoFacadeAssembly)` entry for every Facade assembly that | ||
| must be shipped in the SDK. Facade assemblies are installed into the | ||
| `bin/$(Configuration)/lib/xamarin.android/xbuild-frameworks/MonoAndroid/v1.0/Facades` | ||
| directory. | ||
|
|
||
| The `@(MonoFacadeAssembly)` list can be updated with this shell code on macOS: | ||
|
|
||
| $ cd external/mono/mcs/class/Facades | ||
| $ for d in `find . -depth 1 -type d | grep -v 'netstandard\|System.Drawing.Primitives\|System.Net.Http.Rtc' | sort -f` ; do | ||
| n=`basename "$d"`; | ||
| echo " <MonoFacadeAssembly Include=\"$n.dll\" />"; | ||
| done | pbcopy | ||
|
|
||
| The `@(MonoProfileAssembly)` item group is for non-Facade assemblies, which are | ||
| installed into the | ||
| `bin/$(Configuration)/lib/xamarin.android/xbuild-frameworks/MonoAndroid/v1.0` | ||
| directory. This item group must be updated whenever a new BCL assembly is added. | ||
|
|
||
| The `@(MonoTestAssembly)` item group contains unit test assemblies, executed by | ||
| [`tests/BCL-Tests`](../../tests/BCL-Tests). | ||
| The `%(MonoTestAssembly.SourcePath)` item metadata is the directory name within | ||
| `external/mono/mcs/class` which contains files needed for execution by the unit | ||
| tests. | ||
| The `%(MonoTestAssembly.TestType)` item metadata is the *type* of unit test | ||
| assembly; valid values are `xunit` (for xUnit unit test assemblies), | ||
| `reference` (for ???), and the empty string/not set (for NUnit assemblies). | ||
|
|
||
|
|
||
| <a name="build" /> | ||
|
|
||
| ### Ensure it *builds* | ||
|
|
||
| `make all` only builds a subset of the full Xamarin.Android SDK: support | ||
| for only select ABIs (host OS, x86, armeabi-v7a), only one `Mono.Android.dll` | ||
| version, and *no* builds for Windows support. | ||
|
|
||
| Ensure that `make all` builds *first*. Once that builds, move on to using | ||
| `make jenkins`, which adds support for *all* ABIs, *plus* AOT and LLVM | ||
| compilers, plus Windows binaries. | ||
|
|
||
| See [`Documentation/building/unix-instructions.md`](../building/unix-instructions.md). | ||
|
|
||
|
|
||
| <a name="unit-tests" /> | ||
|
|
||
| ### Ensure Unit Tests *Pass* | ||
|
|
||
| Run the unit tests by using `make all-tests run-all-tests`. | ||
|
|
||
| All unit tests should pass. | ||
|
|
||
| See [`Documentation/building/unix-instructions.md`](../building/unix-instructions.md). | ||
|
|
||
|
|
||
| <a name="create-pr" /> | ||
|
|
||
| ### Create a Pull Request | ||
|
|
||
| Create a Pull Request (PR) on the https://github.com/xamarin/xamarin-android repo. | ||
|
|
||
| Add the **full-mono-integration-build** label to the PR. This ensures that | ||
| the PR build is the full `make jenkins` build. | ||
|
|
||
| The resulting PR *should* be green before merging. | ||
|
|
||
|
|
||
| <a name="api-validation" /> | ||
|
|
||
| ### Check for API Breakage | ||
|
|
||
| The `make run-api-compatibility-tests` target will check the built assemblies | ||
| for API breakage. | ||
|
|
||
| PR builds may report API breakage in the left-hand pane, in an | ||
| **API Compatibility Checks** link. If the API Compatibility Checks link is | ||
| not present, no API breakage was detected. | ||
|
|
||
| For example, this build: | ||
|
|
||
| <https://jenkins.mono-project.com/job/xamarin-android-pr-builder/4577/> | ||
|
|
||
| links to this set of reported API breakage: | ||
|
|
||
| <https://jenkins.mono-project.com/job/xamarin-android-pr-builder/4577/API_20Compatibility_20Checks/> | ||
|
|
||
| **To fix reported API breakage**, the mono sources may need to be updated, *or* | ||
| the [`xamarin/xamarin-android-api-compatibility`](https://github.com/xamarin/xamarin-android-api-compatibility/) | ||
| repo will need to be updated to "accept" the reported breakage, by updating | ||
| the [`external/xamarin-android-api-compatibility`](../../external) submodule | ||
| reference. | ||
|
|
||
| See the xamarin-android-api-compatibility repo for details. | ||
|
|
||
|
|
||
| <a name="qa-validation" /> | ||
|
|
||
| ### Ask for QA Validation | ||
|
|
||
| Asking QA for validation should be done ***last***. | ||
|
|
||
| Once QA approves, the mono bump PR can be merged. | ||
|
|
||
|
|
||
| <a name="mono-archive" /> | ||
|
|
||
| ## Mono Archives | ||
|
|
||
| A "Mono Archive" is a binary package (`.zip` file) which contains *binary* | ||
| mono artifacts, *not* source code. | ||
|
|
||
| See also: | ||
|
|
||
| * The [Mono SDKs Integration project](https://github.com/xamarin/xamarin-android/projects/10) | ||
| * Commit [f970cd50](https://github.com/xamarin/xamarin-android/commit/f970cd50d2c19dcb4b62cc1dd1198c31cc10a2df) | ||
