* [runtime] Mark numerous Mono Embedding API as used only by the MonoVM bridge.
* [runtime] Exclude more unused code from the CoreCLR build.
* There's no tracing in CoreCLR, so no need to process the MONO_TRACE environment
variable (and set the trace options).
* There's no sdb debuggger, so that code can be skipped.
* The profiler support is very different, so skip that code too.
* We don't support AOT, nor aot data files, so skip that.
* [runtime] Stop generating dummy implementations of the Mono Embedding API for CoreCLR.
All of the Mono Embedding API now falls in either of these two categories:
* Only used by the MonoVM bridge.
* Has a CoreCLR implementation.
Which means that we don't need the code to generate dummy implementations for
methods that aren't in any of these two categories anymore.
Those are called respectively inside `xamarin_vm_initialize` and
`xamarin_bridge_initialize` functions.
This fix the **AppContext.GetData always return null for iOS** issue
https://github.com/dotnet/runtime/issues/50290
Thanks for @filipnavara for diagnosing this quicker than anyone else!
Added unit tests to ensure `AppContext.GetData` can read back the values
we're providing at startup.
We need to call coreclr_initialize/monovm_initialize at startup, so do that.
This is a partial implementation, in that we're not setting all the properties
that we should, and also the PINVOKE_OVERRIDE callback is not doing everything
it should either yet.
Ref: #10504.
* [runtime] Download the CoreCLR embedding header file
* [runtime] Create VM-specific code and header files and include them in the build
* [runtime] Move MonoVM-specific initialization to MonoVM-specific code.
Any performance difference will be neglible compared to running the GC, so
there's no compelling reason to use the embedding API.
This makes things a bit easier with CoreCLR, since the new code works there too.
This also required a few changes in delegates.t4 to make code generation for
functions without arguments work correctly.
This also means linking with the runtime packs from .NET instead of the mono archive
(thus we have one less reliance on the mono archive).
We're also using the Xamarin.iOS code for our macOS launch sequence now, since
(at least at first) we're only going to support self-contained .NET macOS apps
(so no need to support a system-installed runtime, which simplifies things a
bit).
* Convert the GCHandles interface from 32-bit ints to pointer size types
This involves:
* Stop using some bits of the GCHandle to store extra flags, instead add an extra
field to store those flags.
* Define a INVALID_GCHANDLE constant and use it instead of 0/NULL. This is not
strictly required, but it makes the code more self-documenting.
* Define a GCHandle type (typedef'ed to void*) and change all variables and parameters
to use it instead of guint32.
* Use our own xamarin_gchandle_* methods (with pointer-sized types) that wraps
the mono_gchandle_* embedding API (which uses 32-bit types) everywhere.
* Update managed code (registrars, runtime code, etc) accordingly.
* [runtime] Make debug code compile.
* Fix typo.
* Fix signature of xamarin_create_gchandle.

`strlen` is part of the list of C API banned by Microsoft.
Also rename a local variable in `Runtime.cs` so grepping the source
files won't show `strlen` outside the `tests` subdirectories.
Some of the fixes done for the warnings have breaking changes. Move back
to int and ensure that we do not have any compilation errors (we are
using -Werror).

## Miscellaneous fixes
* Fixed
`/Users/builder/jenkins/workspace/xamarin-macios/xamarin-macios/builds/mono-ios-sdk-destdir/ios-sources/external/linker/src/linker/Linker.Steps/OutputStep.cs(110,15): error CS0246: The type or namespace name ‘OutputException’ could not be found (are you missing a using directive or an assembly reference?) [/Users/builder/jenkins/workspace/xamarin-macios/xamarin-macios/tools/mmp/mmp.csproj]`
* Changed the name of the method that is used from linker. Because of this commit 6be26771b9
* Added `OutputException.cs` file on `mtouch.csproj`.
* Removing enter_gc_safe and exit_gc_safe because now it's already gc_safe in this part of code, after a mono change.
* Added known exceptions to LLVM exception list.
* Needs `ifdef` because of this https://github.com/mono/mono/pull/17260.
* Bump MIN_MONO_VERSION to 6.8.0.41 and point MIN_MONO_URL to the PR.
* Add ENABLE_IOS=1 and ENABLE_MAC=1.
* Added switch to disable packaged mono build
* [Tests] Ignore tests that fail on 32b.
Ignore the test on 32b, and filled issue: https://github.com/mono/mono/issues/17752
* [Tests] Ignore a couple of tests causing OOM.
Hopefully fixes https://github.com/xamarin/maccore/issues/1659 for good.
* Ignore `MM0135` test on Catalina+ because it needs Xcode 9.4.
* [monotouch-test] Add null checks for teardown when test didn't run because of a too early OS version.
* [CFNetwork]: Http 2.0 requires OS X 10.11 or later.
Check whether `_HTTPVersion2_0` is available and fallback to HTTP 1.1 otherwise.
## Bring HttpClient from CoreFX
* #7346
* This bumps Mono to use https://github.com/mono/mono/pull/17645 (which is the 2019-10 backport
of https://github.com/mono/mono/pull/17628).
* The big user-visible change is in regards to certificate validation, everything below are just
some minor adjustments to tests.
### SocketsHttpHandler
CoreFX uses a completely new `HttpClientHandler` implementation called `SocketsHttpHandler`,
which you can find at https://github.com/dotnet/corefx/tree/release/3.0/src/System.Net.Http/src/System/Net/Http/SocketsHttpHandler.
Since this is not based on the web stack anymore, it does not use any of the related APIs such
as `ServicePointManager` or `WebException`.
### Certificate Validation Changes
There is a new API called `HttpClientHandler.ServerCertificateCustomValidationCallback`.
- https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclienthandler.servercertificatecustomvalidationcallback?view=netframework-4.8
- c1778515a3/src/System.Net.Http/src/System/Net/Http/HttpClientHandler.Unix.cs (L154)
- c1778515a3/src/System.Net.Http/src/System/Net/Http/HttpClientHandler.Windows.cs (L383)
The `ServicePointManager.ServerCertificateValidationCallback` is no longer invoked and on
certificate validation failure, `AuthenticationException` (from `System.Security.Authentication`)
is thrown instead of `WebException`.
At the moment, the `NSUrlSessionHandler` still uses it's own validation callback and also still
throws `WebException` on failure; we should probably look into making this consistent with the
other handlers.
### Minor adjustments related to internal Mono APIs
* `HttpContent.SerializeToStreamAsync()` is now `protected` (changed from `protected internal`).
- src/Foundation/NSUrlSessionHandler.cs: changed overload accordingly.
- src/System.Net.Http/CFContentStream.cs: likewise.
* `HttpHeaders.GetKnownHeaderKind()` is an internal Mono API.
There is a new internal API called `System.Net.Http.PlatformHelper.IsContentHeader(key)`
which exists in both the old as well as the new implementation.
The correct way of doing it with the CoreFX handler is
`HeaderDescriptor.TryGet (key, out var descriptor) && descriptor.HeaderType == HttpHeaderType.Content`
### Minor adjustments to tests.
* `HttpClientHandler.MaxRequestContentBufferSize` is now longer supported, you can set it to
any non-negative value, the getter will always return 0.
See c1778515a3/src/System.Net.Http/src/System/Net/Http/HttpClientHandler.Core.cs (L18).
- tests/linker/ios/link sdk/HttpClientHandlerTest.cs: removed assertion from test.
* `HttpMessageInvoker.handler` is a `protected private` field - in the CoreFX handler, it is
called `_handler` and `private`. This is accessed via reflection by some of the tests, which are
now using the new name.
- tests/mmptest/src/MMPTest.cs: here
- tests/mtouch/MTouch.cs: here
* tests/monotouch-test/System.Net.Http/MessageHandlers.cs:
Adjust `RejectSslCertificatesServicePointManager` to reflect the certificate validation
changes described above.
- FIXME: There was an `Assert.Ignore()` related to `NSUrlSessionHandler` and macOS 10.10;
I removed that to reenable the test because the description linked to an old issue in
the private repo that was referenced by several "Merged" PR's, so it looked to me that
this might have already been fixed - and I also didn't see why it would fail there.
* [Runtime] Enable the -Wshorten-64-to-32 flag and fix all warnings.
We want to enable the -Wconversion but that will raise too many warning
for a single commit. We are enabiling one by one the flags included in
-Wconversion so that we have smaller diffs.
-Wshorten-64-to-32 adds warnings when there is a implicit conversion that
loses integer precision. We are moving all the 32 to 64 conversions to
use 64. Expecially since most of the code changed is related with sizes,
legths and params counts that are never going to be negative.

* [runtime] Clean up public symbols. Fixes#5124.
Clean up public symbols, by:
* Symbols that don't need to be public (most of them), can be private.
* Prefix all public symbols with `xamarin_`.
* Add a test to ensure we don't introduce new public symbols.
* Use C symbols instead of mangled C++ symbols, since those are easier to
handle in the test.
This minimizes the chance of getting into a symbol clash with another native library.
Fixes https://github.com/xamarin/xamarin-macios/issues/5124.

* Revert 4bacab3d5c, it doesn't fix the ios aot problems.
* Bump mono
* [tests] Adjust the MT0137 test for mcs change in behavior.
Starting with mono 5.16 mcs will now add assembly references when the assembly
is only used in attributes (this was already the case for csc in both 5.14 and
5.16, so it seems to be a compatibility change).
Adjust the MT0137 test accordingly.
* [msbuild] Fix parsing of json parser errors to handle trailing periods in the error message.
Fixes this test:
1) Test Failure : Xamarin.iOS.Tasks.Bug60536.TestACToolTaskCatchesJsonException
ColumnNumber
Expected: 2
But was: 0
* Bump mono
* [builds] Install the old llvm binaries into the LLVM36 directory and make the 32 bit builds use that.
* Bump mono
* Bump mono
* [jenkins] Don't give VSTS a fake branch. (#4667)
Something in VSTS changed, and now fake branch names don't work anymore.
So instead use real branch names (and for pull requests I've created a
'pull-request' branch we can use).
* Assembly.LoadFile accepts only absolute path
* [linker] Add new Facade (System.Threading.Tasks.Extensions).
Fixes these MTouch test failures:
1. Xamarin.Linker.SdkTest.iOS_Unified : Facades
Expected:
But was: < "System.Threading.Tasks.Extensions" >
2. Xamarin.Linker.SdkTest.tvOS : Facades

* [mono-sdks] Necessary changes to unify the LLVM provisioning for both iOS and Android. (#4732)
* Bump Mono
* [mtouch] add mixed-mode support (#4751)
* [mtouch] add --interp-mixed option
When enabling this option, mtouch will AOT compile `mscorlib.dll`. At
runtime that means every method that wasn't AOT'd will be executed by
the runtime interpreter.
* [mtouch] Add support to --interpreter to list the assemblies to (not) interpret.
* [msbuild] Simplify interpreter code to use a single variable.
* Fix whitespace.
* [mtouch] Move mtouch-specific code to mtouch-specific file.
* [msbuild] An empty string is a valid value for 'Interpreter', so make it a non-required property.
* [mtouch] Add sanity check for aot-compiling interpreted assemblies.
* Bump Mono
* [linker] Updates SDKs facades list
* Bump mono
* [msbuild] Adds facades which might override default nuget version to framework list
The collision resolver task reads them from here https://github.com/dotnet/sdk/blob/master/src/Tasks/Common/ConflictResolution/FrameworkListReader.cs
* Bump to a VSfM version that can build XM Classic projects.
Store the launch mode in a static variable instead of storing if we're an
extension (since the launch mode also contains that information).
Also pass the launch mode around in Xamarin.Mac's initialization data.
If an extension is sharing code with the container app, then assemblies may be
placed in:
* The container app's Framework directory (for assemblies whose code is
shared, and the build action is 'framework'). We already handle this case.
* The container app's root directory (for assemblies whose code is shared, and
the build action is not 'framework'). This case we didn't handle, and we're
now fixing it.
* In the extension (for assemblies whose code is not shared). We already
handle this case.
Add support for finding assembly-related resources (debug files, config files,
satellite assemblies, aotdata files, etc) in multiple locations:
* The bundle's root directory.
* A pointer-size specific size directory (.monotouch-32|64)
* A framework's MonoBundle directory (and the framework may not be named after
the assembly, which means it's not necessarily possible to deduce the
framework's name at runtime).
* In a container bundle.
Some files may also have an arch-specific suffix.
Make the architecture a suffix instead of infix for aotdata filenames so that
it's easier to compute the filename from the assembly name without passing
printf-style format strings around.
The length argument for `strncpy` specifies how many characters to copy, not
the length of the target string, which makes our usage incorrect.
Fix our usage, and use the `strlcpy` variant instead, which takes the length
of the target string.
And use `strlcat` instead of `strcat`.
Setting this option prints this to stdout:
> Mono Warning: option gen-compact-seq-points is deprecated.
and it's ignored, so just don't set this option.
* [runtime] Use printf on watchOS, NSLog doesn't shown up (by default).
* [runtime] Use a wrapper function for logging.
So that we can chose between printf and NSLog at runtime,
depending on where we're running.
The base directory and config file name is normally set automatically
when we ask Mono to execute the Main function, but in the case of extensions,
there is no Main function, so these values are not set, causing some
features (reflection-only assembly load) to not work correctly.
https://bugzilla.xamarin.com/show_bug.cgi?id=42784
Usually mono does this for other apps, but not for watchOS (where mono doesn't
use signals at all).
watchOS can still raise signals though, so we need to ignore at least SIGPIPE.
