* [mtouch][mmp] Share error.cs and make it safer against FormatException
Beside the obvious code sharing [1] this makes the error reporting code
safer against `FormatException`.
Even with code review this happened a few times in the past - we get
a string that can't format correctly in some error handling code. This
means the `FormatException` must be fixed before we can see the
underlying root issue (delaying bug fixes and support).
Recent changes made for localization makes it harder to review the
original strings (and even harder for translated strings) for
correctness. This means we can end up with something like
```
String.Format ("{0} {1}", "foo");
``
and easily miss it (since they split between different files) if there
are several changes inside a PR.
Finally sprinkle some unit tests :)
[1] we should move everything to use `ProductException` but that will be
for another PR...
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.
Using this option it's possible to test for the presence of a type
reference in both pre-linked and post-linked assemblies.
This makes it possible to detect if
* a 3rd party assemblies are using some specific type you would like to avoid;
* a type reference has been removed during the build (e.g. linker)
Notes:
* Custom attributes are encoded differently and not included in the assembly type references metadata.
* Assembly that define a type `X` do not have a reference (but the definition) of the type (and won't be reported).
If either the pre or post-linked warnings are not useful then it's possible
to add `-nowarn:150x` to exclude the results.
E.g.
* `-nowarn:1502` would not report references in pre-linked assemblies;
* `-nowarn:1503` would not report references in post-linked assemblies;
Finally `-warnaserror:150x` can be used to stop a build that would not
satisfy either the pre or post-linked condition.
* `-warnaserror:1502` would not report references in pre-linked assemblies;
* `-warnaserror:1503` would not report references in post-linked assemblies;
_side note_ same as https://github.com/xamarin/xamarin-macios/pull/7925
except that this one uses the localized mtouch/mmp errors only in master (so far)
- https://devdiv.visualstudio.com/DevDiv/_workitems/edit/947932
- It turns out the linker in some cases can wrap expected exceptions in a outer exception. By drilling in we can produce better errors, again.
- Refactor pipeline exception handling to be shared between mmp/mtouch
## 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.
* [mtouch/mmp] Split out the RunCommand[Async] methods to a separate file so that the generator can reuse more easily.
* [generator] Show proper errors when failing to compile something.
* Fix grammar
* We only need to do a runtime check on watchOS.
* On watchOS assume we're on a ARM64-based CPU as long as we're not on a
ARMv7k CPU.
Fixes an issue where we failed to detect a 64-bit iOS CPU as ARM64-based (in
particular iPhone X's ARM64v8).
We need our 32-bit and 64-bit assemblies to be identical so that we can avoid
duplicating the .dll in fat apps.
One difference used to be that the .dll contained the full path to the
corresponding .pdb ([1]), but we changed cecil to only write the filename
([2]). Unfortunately this change breaks something else, so it has to be
reverted ([3]).
This implements a different solution: we provide a custom symbol writer to
Cecil, which only writes the filename of the pdb in the .dll, not the full
path.

# Conflicts:

* Add a Runtime.IsARM64CallingConvention property.
Determining whether we should use the ARM64 calling convention in P/Invokes
gets more complicated with ARM64_32 (which for our purposes is a 32-bit
architecture).
So add a property on the Runtime class to avoid code duplication, and teach
the linker to optimize any calls to this property to a constant value whenever
possible (and the method is marked as optimizable).
Also change our code to use this new property, and make the corresponding
methods optimizable.
Some shuffling in mmp was required, which meant a little bit more code is now
shared between mtouch and mmp.
* Coding style.
* Test tweaks.
* Improve comment.
* Document new optimization
* Move ILReader to shared linker test code location.
* Disable inlining on armv7k.
* Change IsARM64CallingConvention to a read-only field.
We can give the AOT compiler a constant value for a read-only field, so that
the AOT compiler optimizes away the call to the field by using the constant
value.
This commit does not implement this change for the AOT compiler, but using a
read-only field makes it easy to implement it in the future.
* [linker] Remove non-bitcode compatible code, and show a warning.
Remove code not currently compatible with bitcode and replace it with an
exception instead (otherwise we'll assert at runtime).
Also show a warning when we detect this.
This is quite helpful when looking at watch device test runs to filter out
failures we already know about.
This fixes point #2 in #4763.
* Improve documentation.
* Simplify linker code by using a substep.
* Fix whitespace issues.
* Improve reporting.
* Add support for reporting more than one MT2105 at the same time when making
the errors instead of warnings.
* Only report MT2105 for methods that haven't been linked away.
* Format the error message nicer for properties.
* Tweak a bit for warning tests to pass.
* Use ExceptionalSubStep to provide better error information.
* Adjust where linker warnings/errors are reported from to avoid a NullReferenceException.
- Existing binding projects embed the native libraries within the assembly as managed resource
- This does not scale well and has performance implications
- This PR creates a new property, NoBindingEmbedding which when true processes the building and consumption of binding projects differently.
- Existing binding projects are not affected, they will continue as is
- I've written a full XM test suite and ported a subset to iOS. Since iOS only supports checked in projects, and I didn't want to make the existing situation worse by adding more, I only wrote tests that could use the existing test projects.
-When we complete some form of msbuild testing reform, we'll revisit these tests.
- Remove two files in MyiOSFrameworkBinding that are not used (we use copies elsewhere)
- Remove unnecessary sleep and fix broken touch command
- Output failing test log to console instead of test output
- VSfM does not handle thousands of lines of test failure message well
- Add ability to generate binding projects with LinkWith
* Make sure mtouch.csproj builds using the same compiler arguments as the makefile used.
* Build mtouch.exe using msbuild in the makefile, and clean up the resulting unused make logic.
Partial fix for https://github.com/xamarin/xamarin-macios/issues/4384.
* [ObjCRuntime] Add a BindingImplAttribute.
* [linker] Make ProviderToString an extension method on ICustomAttributeProvider to make it more discoverable.
* [generator] Use [BindingImpl] instead of [CompilerGenerated].
The entire diff is big (89MB), so it can't be gisted. However, most of it is
either removal of `using System.Runtime.CompilerServices;` or the change from
`[CompilerGenerated]` to `[BindingImpl (...)]` like this:
https://gist.github.com/rolfbjarne/8bfda3ed37b956d0342a1c1e9b079244
If I remove those parts of the diff, there's nothing significant left:
https://gist.github.com/rolfbjarne/4156164d6bdb1376366200394eb8a091
* [linker] Teach the linker about the new [BindingImpl] attribute.
In addition to the existing logic where the linker would optimize some
[CompilerGenerated] code (sometimes with additional requirements), it will now
also optimize all [BindingImpl (Optimizable)] code (without any additional
requirements).
* [tests] Add tests to make sure [BindingImpl (Optimizable)] works as expected.
* [linker] Check for [BindingImpl] before [CompilerGenerated] and stop checking for [CompilerGenerated] in XAMCORE_4_0.
Check for [BindingImpl] before checking for [CompilerGenerated], since the
former is more common.
Also stop checking for [CompilerGenerated] (at least to mean that code is
optimizable) in our next non-compatible evolutionary leap (XAMCORE_4_0):
* [introspection] Impl a better typo check.
* [mtouch/mmp] Give users more control over optimizations, and share more code between mtouch and mmp.
1. Add an --optimize flag to mtouch/mmp that allows users to select which
optimizations to apply (or not). This makes it easier to add future
optimizations, and allow users to disable any optimization that causes
problems without having to disable many other features.
2. Share as much optimization code as possible between mtouch and mmp. This
immediately gives a benefit to mmp, which has three new optimizations only
mtouch had: NSObject.IsDirectBinding inlining, IntPtr.Size inlining and
dead code elimination.
This results in ~6kb of disk space saved for a linked Xamarin.Mac app:
* link sdk: [Debug][1], [Release][2]
* link all: [Debug][3], [Release][4]
Testing also verifies that monotouchtest ([Debug][5], [Release][6]) has not
changed size at all, which means that no default optimizations have changed
inadvertedly.

* [tools] Don't enable the IsDirectBinding optimization by default for Xamarin.Mac apps, it's not safe.
* Fix whitespace issues.
* [doc] Document optimizations.
* Officially support optimizations by adding them to the Versions.plist.
* [linker] Improve IntPtr.Size inliner + dead code eliminatior and add tests.
* Properly handle operands for the ldc_i4_s instruction (they're sbyte).
* Fix less-than condition to actually do a less-than comparison.
* Make sure to look up the bitness in the Target, not the Application, since
the Application's value will be incorrect when building fat apps (both
Is32Build and Is64Build will be true).
* Remove unnecessary checks for the IntPtr.Size inliner: this optimization
does not depend on other instructions than the IntPtr.get_Size call, so
remove the checks that verify surrounding instructions. This makes the
IntPtr.Size inliner kick in in more scenarios (such as the new tests).
* Add tests.
* [tests] Add mmp tests for optimizations.
* [tests] Fix XM optimization tests.
* [tests] Fix test build error.
* [mtouch][mmp] Report invalid debug symbols files. Fixes#3200
Try to read the assembly with symbols and, if that fails, warn and
fallback to loading them without symbols.
This fixes cases were it's not easy to update or delete (e.g. nuget)
bad symbols files - so this cannot be an error without causing a lot
of pain.
However it needs to be reported, otherwise it wont be fixed (by the
publisher) and it can limit the debugability of the application and
the usefulness of the stacktraces.
Finally merge most of the resolver's code between mtouch and mmp so
we don't have to fix such issue twice anymore.
note: this needs to be slightly updated once we get a version of cecil
that can give us a more precise error message.

* [mtouch] Improve how we make sure native symbols aren't stripped away. Fixes#51710 and #54417.
* Refactor required symbol collection to store more information about each
symbol (field, function, Objective-C class), and in general make the code
more straight forward.
* Implement support for generating source code that references these symbols,
and do this whenever we can't ask the native linker to keep these symbols
(when using bitcode). Additionally make it possible to do this manually, so
that the source code can be generated for non-bitcode platforms too (which
is useful if the number of symbols is enormous, in which case we might
surpass the maximum command-line length).
* Also make it possible to completely ignore native symbols, or ignore them on
a per-symbol basis. This provides a fallback for users if we get something
right and we try to preserve something that shouldn't be preserved (for
instance if it doesn't exist), and the user ends up with unfixable linker
errors.

Some of the above types from System.dll implemented ObjCRuntime.INativeObject
(from System.dll), which our linker detected as implementing
ObjCRuntime.INativeObject (from Xamarin.iOS.dll), so these types were treated
as custom NSObject subclasses, and the MarkNSObjects linker step would mark
them (which would in turn cause all the other types in the list to be marked).
With that change, these types now implement ObjCRuntimeInternal.INativeObject,
and the linker does not treat them as custom NSObject subclasses anymore.
I think the new behavior is correct: these types do not actually inherit from
the real NSObject/INativeObject, so the linker should not treat them as such.
This may run into different bugs because the linker might now remove more
stuff than before, but that would be a different issue.
This means that the fix is to modify these tests accordingly.

* Bump mono to latest.
* Fix merge conflict that was missed
* [mtouch] Renumber new error which clashes with an existing error number in master.
If both an extension and the container app (or multiple extensions) reference
the same binding assembly for a framework, then we'd error out with an
internal error when trying to copy the framework from both locations to the
container app.
So instead detect when we're trying to copy multiple identical (by comparing
the on-disk contents) frameworks, and only copy one of them.
We'll still show an error if the frameworks are different, but now a nice
MT1035 error with a proper error description instead of an internal error.

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).

We're not storing selectors in fields anymore so this step does nothing
expect iterating over the code.
The step is still needed for `mmp` (for Xamarin.Mac.dll)
Auto-install locally after building in the IDE, so that running mtouch tests
after running the mtouch project doesn't require switching to the command
line.
