In some places we have to provide the macOS version, and in other places the
iOS version. Add a map and the corresponding code to convert between the two,
and use them when needed.
Refactor the Optimizations class to have no conditionally compiled code, which makes
it re-usable from our dotnet-linker code.
Also return any errors or warnings instead of showing/throwing them, which makes
the caller able to show them using whatever means is easiest for the caller.
One test needed an update to the list of valid optimizations, because we now have
a per-platform map of valid optimizations, instead of just a iOS/tvOS/watchOS vs
macOS split ('remove-unsupported-il-for-bitcode' is only valid for watchOS, and now
we say so, while we previously said it was a valid optimization for iOS and tvOS
as well, even though we'd warn about it and do nothing if you tried to set it).
* Port the interdependent-binding-projects test to .NET (it's the simplest
test project we have with binding projects).
* Add a lot of the shared source code for mtouch/mmp to dotnet-linker, and
make it compile. Most issues were fixed by adding a few stubbed out classes,
since there are large chunks of the mtouch/mmp code we're not using yet, so
stubbing out while things are being implemented works fine.
* Add a step in dotnet-linker for loading the linker output (the linked
assemblies) into our bundler code.
* Add another step in dotnet-linker to extract native resources from binding
libraries.
* Augment the build process to take into account the native resources we found
in any binding libraries.
This fixes an issue where mtouch would complain about a missing --target-framework argument when it's not actually needed:
/Library/Frameworks/Xamarin.iOS.framework/Versions/Current/bin/mtouch --launchsim bin/iPhoneSimulator/Release/MyApp.app [...]
error MT0086: A target framework (--target-framework) must be specified.
what makes this worse is that passing --target-framework to mtouch makes
mlaunch fail, because mlaunch doesn't accept a --target-framework argument.
A few changes are required to have an Application instance at hand when we need to
get the ProductName from it.
This is necessary for .NET, since there will be a single linker library for all platforms,
which means we can't use a constant.
* Create a simple Xamarin.Utils.Execution class that can handle all our
process execution needs:
* Captures or streams stdout/stderr (in UTF8).
* Supports async
* Supports a timeout
* Does not depend on any other source file we have, only uses BCL API.
* Have the execution helper classes from mtouch/mmp
(Xamarin.BundlerDriver.RunCommand) and the tests
(Xamarin.Tests.ExecutionHelper) use this new class.
* Some simplifications were made:
* All API that took a string array for the environment now takes a
Dictionary<string, string>.
* The Driver.RunCommand methods were split out to a separate file. This
file also contains a Verbosity field, which is conditioned on not being
in mtouch nor mmp, which makes including this file from other projects
simpler (such as bgen - in particular bgen was modified to use this
Verbosity field instead of its own).
Fixes this:

* [msbuild] Adjust tests after switching to use --reference instead of -r.
* Update according to review.
* [mmp] Remove --registrar:il.
The IL generator was what MonoMac had before the dynamic/static registrar code
got shared between MonoTouch and MonoMac. The IL registrar been gone for
years, and as far as I know nobody ever used --registrar:il, even though it
was provided as a compatibility option in the beginning (we still had the IL
registrar around for a while after adding the static+dynamic registrars, until
it was completely replaced by the dynamic registrar).
So just remove this option, if anyone ever used it they can replace it with
--registrar:dynamic.
* [mtouch/mmp] Keep bundler-specific code in its corresponding file.
* Move much of ErrorHandler.cs into a partial class in ErrorHandler.tools.cs,
which is referenced by mtouch and mmp (but not our runtime).
* Add ErrorHandler.runtime.cs for runtime-specific bits, including a simpler
version of ErrorHandler.Show. In particular this gets rid of the call to
Environment.Exit, which should never happen at runtime.
* Rename MonoTouchException and MonoMacException to ProductException, which
allows us to remove a lot of ifdefs.
* This required moving Application.LoadSymbols and Target.LoadSymbols to
shared mtouch/mmp code.
That's in /Library/Frameworks/Xamarin.Mac.framework/Versions/Current/SDKs/Xamarin.macOS.sdk/[lib|include]
This allows for a bit more code share between mtouch and mmp.
* Rearrange files in Xamarin.Mac a bit to ease code sharing between mmp and
mtouch, by putting mono's static and dynamic libraries in
/Library/Frameworks/Xamarin.Mac.framework/Versions/Current/Sdks/Xamarin.macOS.sdk
to match how Xamarin.iOS does it.
* Don't use 'usr' as an intermediate directory. This removes another special
case.
* Share many of the functions and properties that return specific directories,
and document (as comments) what each function/property is supposed to
return.
We're using the Release configuration to build the mtouch and mmp binaries
that we ship, which means that we can use the Debug configuration for
debugging from an IDE, and use the standard conditional compilation symbols to
identify that case.
* [mtouch/mmp] Only use stdout from xcrun as the path of the file that was found. Fixes#8147.
xcrun can print stuff to stderr even if it succeeds and prints what it found
to stdout, which means we have to separate stdout and stderr when capturing
xcrun's output.
This also means that we need a few changes to our RunCommand API:
* Add support for capturing stdout and stderr separately by providing
different callbacks/StringBuilder instances.
* Use overloads instead of default arguments, because with default arguments
we end up with ambiguous matches in a lot of places with the new overloads.
Fixes https://github.com/xamarin/xamarin-macios/issues/8147.
* [tests] Fix mmptest build.
* [mtouch/mmp] Fix process log output.
* Unify target framework code between mtouch and mmp.
* Simplify the code in mmp: have three possible valid target frameworks for
most of code, and add special code to handle setting any other valid target
frameworks to redirect to one of those three valid target frameworks (and
warn if given any of those valid, but not "main", target frameworks). Any
other code can then depend on the target framework having exactly one of
those specific values, which means we can make IsUnified* variables
convenience properties instead.
* Unify a bit more of the argument parsing code between mtouch and mmp, since
that made a few other things easier.
* Add TargetFramework.IsValidFramework to have one validation implementation.
* Move the implementation of TargetFramework.MonoFrameworkDirectory to mmp
itself, it's not really related to the target framework.
* Remove Driver.IsUnified and IsClassic from mmp, they're not used anymore.
* Formally deprecate --xamarin-[full|system]-framework in mmp, they've really been deprecated for many years.
* Remove LinkerOptions.TargetFramework, it's not used anymore.
* Get rid of mmp's userTargetFramework fried, it's duplicated with the
targetFramework field.
* Add a few tests, and tweak others a bit.
Breaking changes:
* Both mtouch and mmp require --target-framework now. The only direct
consumers should be the MSBuild tasks, which already pass --target-framework
all the time. This simplifies code, and removes assumptions.
This optimization can be enabled when it's not possible to use the
managed linker (e.g. **Don't link**) or when the managed linker cannot
remove references to deprecated types that would cause an application
to be rejected by Apple.
References to the existing types will be renamed, e.g. `UIWebView` to
`DeprecatedWebView`, in every assemblies.
The type definition is also renamed (for validity) and all custom
attributes on the types and their members will be removed.
Code inside the members will be replaced with a
`throw new NotSupportedException ();`.
The msbuild test app `MyReleaseBuild` has been updated to test that the
optimization is working as expected (device builds are slow so reusing
this test has little impact in test time).
Basically the test ensure that `UIWebView` is used and cannot be removed
by the compiler (optimization) or the managed linker (since it's
referenced). Since the optimization is enabled then we can `grep` then
final `.app` directory to ensure there's no mention of `UIWebView` inside
any of the files that would be submitted.
The application can be run, by itself, and will turn green if OK, red if
`DeprecatedWebView` can't be found (skeleton replacement for `UIWebView`)
or orange if a `NotSupportedException` is thrown.
Finally introspection tests have been updated to skip over the deprecated
(and renamed) types. It should not be an issue right now, since this
optimization is not enabled by default, but it made testing easier.
We can end up with a format that has `{x}` inside it and no argument. If
this is logged (which depends on verbosity level) then we end up with an
uncaught exceptions and either `MT0000` or `MM0000` errors.
This happens in #7904 due to other, unrelated, issues (a variable is not
expanded) but this can happen in other circumstances, e.g. a file could
be named `{x}.cs`.
The easy fix is to use the right `Console.WriteLine` overload if there
are no arguments provided. This is always good since it avoid an non
required call to `String.Format`.

* Implement a different escaping/quoting algorithm for arguments to System.Diagnostics.Process.
mono changed how quotes should be escaped when passed to
System.Diagnostic.Process, so we need to change accordingly.
The main difference is that single quotes don't have to be escaped anymore.
This solves problems like this:
System.ComponentModel.Win32Exception : ApplicationName='nuget', CommandLine='restore '/Users/vsts/agent/2.158.0/work/1/s/tests/sampletester/bin/Debug/repositories/ios-samples/WorkingWithTables/Part 3 - Customizing a Table\'s appearance/3 - CellCustomTable/CellCustomTable.sln' -Verbosity detailed -SolutionDir '/Users/vsts/agent/2.158.0/work/1/s/tests/sampletester/bin/Debug/repositories/ios-samples/WorkingWithTables/Part 3 - Customizing a Table\'s appearance/3 - CellCustomTable'', CurrentDirectory='/Users/vsts/agent/2.158.0/work/1/s/tests/sampletester/bin/Debug/repositories', Native error= Cannot find the specified file

* Rework process arguments to pass arrays/lists around instead of quoted strings.
And then only convert to a string at the very end when we create the Process
instance.
In the future there will be a ProcessStartInfo.ArgumentList property we can
use to give the original array/list of arguments directly to the BCL so that
we can avoid quoting at all. These changes gets us almost all the way there
already (except that the ArgumentList property isn't available quite yet).
We also have to bump to target framework version v4.7.2 from v4.5 in several
places because of 'Array.Empty<T> ()' which is now used in more places.
* Parse linker flags from LinkWith attributes.
* [sampletester] Bump to v4.7.2 for Array.Empty<T> ().
* Fix typo.
* Rename GetVerbosity -> AddVerbosity.
* Remove unnecessary string interpolation.
* Remove unused variable.
* [mtouch] Simplify code a bit.
* Use implicitly typed arrays.
* Build native code with -std=c++14.
Apple's headers now require -std=c++14 to compile their headers in C++ mode.
This fixes a compile error that would occur with the PhotosUI framework when
compiling code for C++.
* [mmp] Use -std=c++14 when compiling.
* Fix command line output.
* [mmp] Add all source files at the end, so they all get the -x clang argument applied.
* Limit when using c++14 in mtouch according to language.
Also limit the output from the native compiler, so that we don't overload the
IDEs with output if the native compiler produces tens of thousands of errors.
