It does not make sense to support incremental builds for the simulator (since
no AOT compilation is done), it just makes the test matrix more complicated.
So simplify things by removing support for incremental builds.
We also ignore any (other) --assembly-build-target arguments, because building
to frameworks doesn't make sense either in the simulator.

- SecCertificateCopyEmailAddresses behaves differently on macOS than iOS with
macOS getting the "documented" behavior of returning an empty array and iOS
returning null.
- Fix the test to just accept null or 0 elements
This dramatically decreases the size of watchOS apps built for debug when
using frameworks, because it ends up removing all the bitcode from
Mono.framework.
https://bugzilla.xamarin.com/show_bug.cgi?id=55256
Of particular importance is if we're building for LLVM or not: this fixes a
bug where we wouldn't pass --llvm to the AOT compiler when compiling
assemblies to frameworks (which we do when sharing code).

* Remove the MT0008 test, since the error will never be shown again.
* Check non-existent root assemblies and report MT0018 instead of MT0007 if
they look like command-line arguments.
* Collect all MT0018/MT0007 errors before reporting any of them.
* Use Visual Studio instead of Xamarin Studio.
* VS doesn't have mdtool, it has vstool.
Also there's no need to manually invoke the mdtool.exe executable anymore
(which we did because the mdtool executable had a min macOS version of 10.9,
and we used to build tests on older macOS versions [1]), since now we only run
tests on older macOS versions, we don't build those tests there.

* [CoreText] Fix bug 54148 - CoreText.CTParagraphStyle does not pick up settings from CTParagraphStyleSettings
https://bugzilla.xamarin.com/show_bug.cgi?id=54148
CTParagraphStyle float properties have the incorrect float return type,
the headers state this API's returns CGFloats (aka nfloat) instead of floats
this used to work ok fetching them due to there is no difference in size
for 32 bits devices but once 64 bit devices appeared the API began to fail
The actual method that fetches the values `CTParagraphStyleGetValueForSpecifier`
asks for the size of the returned data and we used to give the size of a float
which is incorrect in 64 bits devices and the API call just correctly returned
false because it could not write back the value to us.
Added tests for the full properties available on CTParagraphStyle
* Add comment about the weird Dispose method implementation in CreateFromSettings
We want to copy the aot data for both the 32-bit and the 64-bit versions of an
assembly even if the 32-bit and 64-bit versions of the assembly are identical.

- Before this mmp was not adding -framework, -weak_framework consistently on non-static registrar use cases
- GatherFrameworks was previously not ported from mtouch, and did not work as DeploymentTarget was unset in mmp
- Added verbose prints so users can determine why various framework linkages are added
- Fixed an issue where duplicate were being added due to HandleFramework shoving args by hand
- Tested with auto test and https://github.com/chamons/xm-version-regression-test manual test
Roslyn, when building in release, can remove unused fields. That broke
a test that ensure OpenTK types got preserved correctly (because the

This optimization is now limited to Xamairn.iOS.dll. 3rd parties .dll
size savings were not large enough to justify two different (32/64)
assemblies in the application bundle.
It's likely this change that resulted in incorrect fixes like:
- if (classic_or_sim || single_arch) {
+ if (IsMainExecutableDual ())
which reversed the condition and later
580f502777
which disabled DEBUG - but we don't have IL on release so it became

- In some build cases this chunk of code:
<ItemGroup Condition=" '$(NoCompilerStandardLib)' == 'true' and '$(NoStdLib)' != 'true' ">
<!-- Note that unlike VB, C# does not automatically locate System.dll as a "standard library"
instead the reference is always passed from the project. Also, for mscorlib.dll
we need to provide the explicit location in order to maintain the correct behaviour
-->
<_ExplicitReference Include="$(FrameworkPathOverride)\mscorlib.dll" />
</ItemGroup>
would trigger and force us to use mscorlib from system mono. That does not work well.
- By setting FrameworkPathOverride, we can get the right mscorlib
- However, that ItemGroup happens outside of a target, so we must move our setting to match for it to take effect
* [tests] Don't create test packages by default.
Don't create test packages by default, instead add a new target to create test
packages. This new target is called on wrench, which means the packages will
still be created when needed, but they won't be built locally in every build
(and if a packaged test fails to build, it won't fail the entire build).
* [tests] Use a project reference instead of assembly reference for GuiUnit.exe
Use a project reference instead of assembly reference for GuiUnit.exe, so that
the GuiUnit reference is automatically built if necessary.
This also makes it required to build a sln for Classic (since mdtool can't
find referenced projects from a csproj).
In a6b9c28975 I fixed SystemSoundTest.FromFile
to not crash randomly, and at the same time I added an assert to ensure that
the playback completion handler is called properly, with a 10s timeout.
Which won't work, because the audio file is 23s long.
There's no need for a 23s audio file, so the fix is simple: cut the audio file
to 0.3s instead.

Add an assembly registration event, that allows apps to opt out of
Xamarin.Mac's default behavior to recursively load every assembly referenced
by the entry assembly.
This is only for Xamarin.Mac, since it does not make sense to have this API in
Xamarin.iOS because assemblies are statically registered at build time.

We turn the MDLMesh constructors into static ones because we don't want to lose the shape name.
Also, the signatures of these constructors differ so it would not be possible to use an enum to differentiate the shapes.

There's a lot of noise from the header diff, e.g. tabs changed to spaces,
but very few actual changes.
Note that there's more macOS specific code to review but this PR
handles iOS, tvOS and watchOS changes.
* Updated API to reflect Xcode 8.3 beta 1 changes
* This commit also fixes availability metadata to avoid duplicating it
by moving member availability metadata into its container class where
possible.
* Enables VideoToolbox tests for tvOS.
Covers iOS, tvOS and macOS (no Metal on watch yet)
Most new members are _marked_ as @required (but are not really) by
Apple. We cannot make them `abstract` as it would be a breaking change.
The new field and both selectors are not really part of tvOS.
The field is not used anywhere (from available API).
The selectors are on a category on a type that is not part of tvOS.
Sadly they do not get annotated directly and require external data.
* introspection-ios
MPMusicPlayerControllerMutableQueue and MPMusicPlayerControllerQueue's headers show no trace of NSCoding, NSSecureCoding or NSMutableCopying therefore we're skipping them.
The exact values are not what we need to test for and varies with
different OS versions - making tests fails for no good reason (i.e.
they are not canary used to detect changes)

Apparently Xcode 8.3 does not like the iPhone 5s simulator, and deletes it.

When [Async] was used on a member of a [Model][Protocol][Basetype]

Currently we get a CS2019 warning whenever we use AsyncAttribute
because we ignore the `result` variable on methods whose return
type is != `void` which is the expected behaviour.
This is specially more annoying on third party bindings,
the generated code did not disable this warning so you get
an "unfixable" warning on the generated code and the user
has no way to fix this on their own.
We now disable and restore CS2019 in the generated code as needed.
Nobody likes warnings that are not their fault.
Added unit test.

var result = BarString(arg1, (obj_) => {
if (obj_ != null)
tcs.SetException (new NSErrorException(obj_));
else
tcs.SetResult (true);
});
return tcs.Task;
}

tcs.SetResult (true);
});

Modified the introspection test to repor this, updated documentation
and update API definitions reported by introspection.
SystemSoundTest.FromFile was requesting to be called back when the sound
completed playback. This causes problems when the sound is disposed after it
has started playing, because in that case disposing it won't prevent the
callback from being called, but instead random InvalidCastExceptions / crashes
would occur.

The Advice attribute used in our bindings was not making

Also added unit test for it
* [generator] Merged PrintFooAttributes into one
Merged PrintPlatformAttributes, PrintPreserveAttribute and
PrintAdviceAttribute into a single method PrintAttributes.
This is due to sometimes we call three times in a row the same method:
```csharp
PrintPlatformAttributes (pi.GetGetMethod ());
PrintPreserveAttribute (pi.GetGetMethod ());
PrintAdviceAttribute (pi.GetGetMethod ());
```
We now do
```csharp
PrintAttributes (pi, platform:true, preserve:true, advice:true);
```
Also removed a not used instance (internal field) of AdviceAttribute
* [Darwin] Fix kqueue/kevent bindings to actually work.
Fix kqueue/kevent bindings to actually work. The P/Invoke signatures were
badly broken (missing an argument), so there's no way this could ever have

add overloads that do the right thing.

In some cases you will find **static** members inside categories like in the following example:
```objc
@interface FooObject (MyFooObjectExtension)
+ (BOOL)boolMethod:(NSRange *)range;
@end
```
This will lead to an **incorrect** Category C# interface definition:
```csharp
[Category]
[BaseType (typeof (FooObject))]
interface FooObject_Extensions {
// Incorrect Interface definition
[Static]
[Export ("boolMethod:")]
bool BoolMethod (NSRange range);
}
```
This is incorrect because in order to use the `BoolMethod` extension you need an instance of `FooObject` but you are binding an ObjC **static** extension, this is a side effect due to the fact of how C# extension methods are implemented.
The only way to use the above definitions is by the following ugly code:
```csharp
(null as FooObject).BoolMethod (range);
```
The recommendation to avoid this is to inline the `BoolMethod` definition inside the `FooObject` interface definition itself, this will allow you to call this extension like it is intended `FooObject.BoolMethod (range)`.
```csharp
[BaseType (typeof (NSObject))]
interface FooObject {
[Static]
[Export ("boolMethod:")]
bool BoolMethod (NSRange range);
}
```
We will issue a warning (BI1117) whenever we find a `[Static]` member inside a `[Category]` definition. If you really want to have `[Static]` members inside your `[Category]` definitions you can silence the warning by using `[Category (allowStaticMembers: true)]` or by decorating either your member or `[Category]` interface definition with `[Internal]`.
- Significant changes to target file under msbuild, ImplicitFacade processing in particular
- Tests are disabled due to https://bugzilla.xamarin.com/show_bug.cgi?id=53164 where we can't tests local target files only global
- Requires a mono msbuild with 95ab657a90 for tests to pass
- Until then, this is a workaround:
sudo cp /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/msbuild/15.0/bin/Roslyn/System.Reflection.Metadata.dll /Library/Frameworks/Mono.framework/Versions/Current/lib/mono/msbuild/15.0/bin/
Taken out of our Xcode8 post-mortem: it's easy to forget (while adding)
or miss (while auditing) a `[Async]` attribute on the API that would
benefit from them.
API that are decorated with either:
* [Obsolete] (managed); or
* [Obsoleted] or [Deprecated] (native)
are not to be added *Async methods (or at least be reported as missing)
This also includes updated introspection tests that found the missing *Async API., ensuring that future API addition will immediately notice is an `[Async]` sounds useful.
A `[Native]` enum is either 32 bits or 64 bits depending on the CPU,
i.e. it's a `NS[U]Integer`. However the managed representation is
*always* 64 bits, a `long` enum, which means it cannot be used
directly (without a cast) when declaring code that match native.
This also enable us to remove the hack from PR1751 to ignore some
generated trampoline code.

Presently we're looking if enums decorated with [Native] are used, just
like we do for p/invokes and delegate types decorated with a
[MonoNativeFunctionWrapper] attribute.
Testing properly required to add a property to MonoPInvokeCallbackAttribute
so we can get back the type given as it's argument.
* Also check for generics in delegates, ref: #42699
* Ignore failures filed as https://bugzilla.xamarin.com/show_bug.cgi?id=53058
We cannot use generics in native signatures but, with some care (and
generator work), we can still expose nullable on our public delegate API.
AUImplementorStringFromValueCallback is presently the only case of such
an API.

Fix detection of fat executable to only return true if we have both a 32-bit
and a 64-bit architecture (which is what the `IntPtrSizeOptimization` test
needs to know), and not more than one architectures (since that can be
`armv7`+`armv7s`, i.e. two 32-bit architectures).
mcs will miscompile using statements that has a catch clause that returns
early (by using 'return;') and a finally clause with await (the using's
variable won't be disposed).
So refactor a little bit to avoid returning early from inside a using
statement.
The `CFStreamEventType` enum is based on `NSUInteger`. The native delegate
CallbackDelegate was using it directly and that made it incorrect on 32
bits platforms.
We have introspection tests to check enums on p/invoke, but it seems they
don't cover native delegates - decorated with [MonoNativeFunctionWrapper]
That's to be added in a different PR.

Make the top-level test name for equivalent tests between iOS and Mac have the
same name, so that these tests are grouped together.
For instance: we used to have a System-Mac tests and System tests (the latter
being iOS tests), now there are just System tests, and nested inside are both
the Mac and iOS System tests.
Allow creating temporary apps/extensions multiple times without re-creating temporary directories.
This makes it possible for tests to call CreateTemporaryApp|Extension multiple
times with different code, and have only the actual managed assembly change
between each time (which is useful for tests that verifies that cached builds
are used properly).
Warn if mtouch loads an assembly from a different location than requested
(which might be because there are multiple assemblies with the same name).
Also rework the MT0023 check a bit by explicitly loading the root assembly
first, and then detecting if any loaded assemblies matches the root assembly.
This results in code that's a bit more obvious, and it also works correctly
with extensions (previously the entire MT0023 check was skipped for
extensions).
Assemblies can now be in frameworks.
Assemblies can also be in container apps (in their root directory, as well as
in frameworks in the container app).
So use the simplest brute-force method to find assemblies: look everywhere.
This makes dylibs automatically have the correct dylib id, which means no
fixups are required.
For instance: we'd build libpinvokes.armv7.dylib from libpinvokes.armv7.m,
which by default ends up with a dylib id of "libpinvokes.armv7.dylib". With
this fix no change is required, since we now build armv7/libpinvokes.dylib
from armv7/libpinvokes.m.
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.
Create a custom AssemblyCollection class that contains a dictionary with
assembly identity (name) -> Assembly mapping.
This also means that we can detect if we end up loading multiple assemblies
with the same identity, and show an error in that case (even if that case
should never happen since we cache assemblies based on the identity, it's nice
to have code that ensures it).
Sometimes, when the stars align, fastsim can build an app in less than a

NSNumber BoolMethod (int arg1);

Use @rpath instead of @executable_path in dylibs, since it allows us to be
more flexible when placing dylibs in the app.
In particular with this change it's trivial to put libmonosgen-2.0.dylib in
the container app, and reference it from extensions.
HFS timestamp resolution is 1 second, which means that we can't distinguish
files modified again within 1 second. This means that this test will fail more
often the faster we make mtouch, so add a forced sleep to make sure we don't
do things faster than the file system can keep track of.
Performance tests
-----------------
This is for a new watchOS extension project, built for release.
* The default (currently -O2) optimizations: 41s ( baseline ) 30.027.060 bytes ( baseline )
* All optimizations disabled (`--llvm-opt=all=`): 17s (-24s = -59%) 32.978.312 bytes (+2.951.252 = +10%)
* Optimized for size (`--llvm-opt=all=-Os`): 36s ( -5s = -12%) 28.617.408 bytes (-1.409.652 = -5%)
* Optimized for more size (`--llvm-opt=all=-Oz`): 35s ( -6s = -15%) 28.601.016 bytes (-1.426.044 = -5%)
* Optimized slightly (`--llvm-opt=all=-O1`): 35s ( -6s = -15%) 28.666.556 bytes (-1.360.504 = -5%)
* Optimized a lot (`--llvm-opt=all=-O3`): 41s ( 0s = 0%) 30.403.996 bytes (+ 376.936 = +1%)
Conclusions
-----------
* The fastest build by far (less than twice as fast) is if optimizations are
disabled, but this adds a 10% size penalty (~3 MB in this test case),
compared to the baseline, and 15% size penalty (4.3 MB) compared to -Oz.
* -Oz seems to have the best overall results: at least as fast as any other
optimized build, and the smallest app as well.
Caveats
-------
Some optimizations might not work the AOT compiled code. The resulting
binaries have not been tested.
Event sequence:
* mtouch is executed with the linker disabled.
* The linker pipeline copies all input assemblies (since the linker is
disabled the assemblies don't change) into the PreBuild directory. This will
keep the original timestamps of the input assemblies.
* mtouch is executed again, when none of the input assemblies changed.
* The linker pipeline will re-execute, because it will see that at least one
of the input assemblies (at least the .exe) is newer than at least one of
the assemblies in the PreBuild directory (usually a framework assembly,
because those have the original timestamp from their install location).
Fix:
Touch all the assemblies in the PreBuild directory after the linker pipeline
executes the first time. This way the second time mtouch is executed, it will
find that all assemblies in the PreBuild directory have timestamps later than
all the input assemblies, so it will load the cached linked assemblies,
instead of re-executing the linker pipeline.
* [xharness] Show test xml files in the html report.
* [xharness] Force links to xml files to show up in a new top-level window.
Jenkins shows the html report in an iframe, and links will load in that
iframe. This means that the browser renders the contents of the link as if it
was html, and rendering xml as html results in a blank page.
So set the target attribute on links to xml files, so that those xml files
open as top-level pages, and then the browser will rendering the xml like xml.
The native linker treats object files (.o) and static libraries (.a files,
which are archives of .o files) differently.
The native linker will always include object files into the executable:
$ echo "void xxx () {}" > foo.m
$ clang -c foo.m -o foo.o -arch x86_64
$ ld foo.o -dylib -o foo.dylib -macosx_version_min 10.12 -arch x86_64
$ nm foo.dylib
0000000000000fe0 T _xxx
However, if the object file is inside a static library:
$ echo "void xxx () {}" > foo.m
$ clang -c foo.m -o foo.o -arch x86_64
$ ar cru foo.a foo.o
$ ld foo.a -dylib -o foo.dylib -macosx_version_min 10.12 -arch x86_64
$ nm foo.dylib
<no output>
This means that our testing library (libtest.a) which is a fat library of
_object files_, do not show the problems reported in bug #51548.
So:
a) I've fixed the creation of libtest.a to be a fat library of _static
libraries_. This causes the `FastDev_LinkWithTest` test to fail exactly
like in bug #51548.
b) I've made mtouch pass `-u <native symbol>` to the native linker, for every
native symbol referenced in a managed assembly, when creating a dylib.
Amazingly this seems to work fine even with symbols to Objective-C classes
(`_OBJC_CLASS_$_<class name>`).
c) This also required adding support for collecting the Objective-C names of
all managed types registered with Objective-C to the linker. The
information is already available in the static registrar, but that would
require us to make sure the static registrar is executed before compiling
dylibs, which means those two tasks won't be able to run in parallel (also
there's no guarantee we'll even run the static registrar).

TL&DR: This is *how* it should be done and tested, it's not complete
(single, simple case) nor the most interesting case ;-)
The trick is to make sure each case is covered by tests so a mono
_bump_ won't give us a BCL that does not conform to what the linker
expect.
What's the impact ?
1. There is the expected reduction of metadata in mscorlib. Since both
methods don't call other API there's no indirect effect (removal).

Don't create multiple writer streams for the same underlying file, instead
store the writer stream on the log instance, and return it whenever needed.
This fixes an issue where there would be multiple writer streams, which could
cause exceptions when creating more writer streams (access defined errors
because the file is already open).
* [tests] Use the target directory from the loaded configuration.
* [xharness] Find the root directory based on xharness.exe's location (unless specified).
* [tests] Add makefile target to generate test config using the system XI.
* [xharness] Don't copy a ExecutionResult before executing.
The source might be an ignored test, even though the cloned task isn't, so if
we copy the ExecutionResult we might unexpectedly ignore the cloned task.
* [xharness] Provide better failure message for failing mac tests.
Unexpected exceptions are now caught in a more central location
(TestTask.RunInternalAsync), which means it's not necessary to catch
unexpected exceptions in other places (so those catch handlers have been
removed).
Additionally we now set the failure message when such an exception occurs, in
addition to writing the full exception details to a custom log file.
Both are our own creation and can be worked around with the `Delegate`
and `DataSource` properties (or the `Weak` ones).
We'll revisit this for `XAMCORE_4_0` as the test will fail again.
With this commit the remaining failures for tvOS should all be fixed
[FAIL] `UICollectionView.get_Source` return type `UICollectionViewSource` is a concrete type `[Model]` and not an interface `[Protocol]`
[FAIL] `UICollectionView.set_Source` includes a paramater of type `UICollectionViewSource` which is a concrete type `[Model]` and not an interface `[Protocol]`
[FAIL] `UITableView.get_Source` return type `UITableViewSource` is a concrete type `[Model]` and not an interface `[Protocol]`
[FAIL] `UITableView.set_Source` includes a paramater of type `UITableViewSource` which is a concrete type `[Model]` and not an interface `[Protocol]`
We're shipping mlaunch now, which means we have other file system locations
where it might be.
Also don't look in Xamarin Studio anymore, it will always be an old version,
instead check the system's Xamarin.iOS version.
* Existing `.ctor(object[])` now
* changed to `params` (not a breaking change);
* accept `NSString`, along with `string` and `UIImage`;
* Added `.ctor (NSArray)` (exposing the generated code to ease subclassing)
* Added `.ctor (params NSString[])`
* Added `.ctor (params string[])`
* Added `.ctor (params UIImage[])`
Also adds unit tests for all of them.

The existing code was cheating and returned a managed only instance with a `nil` handle. That was fine in many cases but some API (e.g. UISegmentedControl) don't like that (i.e. don't react like a normal, empty NSArray was supplied). It's also the right thing to do since the current behaviour is not guaranteed to remain identical on future updates of the OS.
Unit tests updated.
