More corelib cleanup (dotnet/coreclr#26993)

* Make relevant types static (mostly Interop)

* Fix a few stray semicolons

* Remove unnecessary locals

Some can be removed entirely, some can be replaced by discards.

* Remove unnecessary usings

* Move Unix-specific helper method to TimeZoneInfo.Unix.cs

* Remove duplicated code

* Remove duplicative checks

* Remove [ThreadStatic] initialization

These are all the default values and wouldn't be necessary for any static, but inline initialization for [ThreadStatic]s is particularly unuseful (and in non-default cases problematic) because the fields are only set to these values on the initializing thread.

* Fix methods whose return value is never used

* Use string.IsNullOrEmpty

* Remove unnecessary field initialization

All ctors overwrite these values.

All such statics were being handled incorrectly in the
GetElementTypeInfo, leading to an incorrect offset being passed to the
JIT and a crash at runtime.

4 years agoReuse managed test components across all *nix flavors (dotnet/coreclr#26581)
Tomáš Rylek [Thu, 26 Sep 2019 00:35:57 +0000 (17:35 -0700)]
Reuse managed test components across all *nix flavors (dotnet/coreclr#26581)

Today CoreCLR pipelines build tests on the same OS flavors they are
supposed to run on. This is wasteful as we produce identical
managed test artifacts on OSX, Linux, Linux_musl and Linux_rhel6.

With this change, the pipeline construction analyzes the set of
OS / architecture combos to run tests on and picks the "best"
OS (or rather the OS that runs on the fastest lab HW) for build
of the managed test components.

Native test components are newly built as part of the product build
as these do need to be built separately for each targeting OS.
Product build zips them up and publishes them to Azure as an artifact
that gets subsequently downloaded and stitched together with
managed test components in the test run job.

Implementation-wise the change basically proceeds in two steps.
In platform-matrix.yml we first identify the exact set of OS / arch
combos to run. Using this information we subsequently identify
the OS to build managed components on for each combo; this information
is passed to test-job.yml which skips managed test build for those
OS-es that are expecting the managed components to be built on a
different OS.

Product build (build-job.yml) contains the additional logic to
build native test artifacts and publish the to Azure for perusal
by the test run job that downloads and unzips both managed and native
artifacts into the final test folder before publishing to Helix.

Thanks

After I finally managed to make my infra change to reuse managed
test artifacts across various *nix flavors work on the CoreCLR-CI
Pri0 pipeline, I proceeded to testing the official build which
uncovered a single Pridotnet/coreclr#1 test violating the independence principle:

<pre>
Loader\AssemblyDependencyResolver\AssemblyDependencyResolverTests\AssemblyDependencyResolverTests.csproj
</pre>

This test project uses the clause

<pre>
    &lt;RequiresMockHostPolicy&gt;true&lt;/RequiresMockHostPolicy&gt;
</pre>

which makes the script CLRTest.MockHosting.targets emit an
OS-specific name of the mock hosting dynamic library to the
execution .sh script which then becomes non-portable between
Linux and OSX because they use different extensions for dynamic
libraries (so / dylib).

My proposed change fixes this by modifying the targets file to
emit just the library name without the extension and append
the appropriate per-OS extension in CoreRun.

2) Based on JanV's suggestion I have added a somewhat hacky logic
to exclude the "testhost" folder when building the entire Pridotnet/coreclr#1

Fix issue with locals overlapping out of scope GCFrame (dotnet/coreclr#26763)

* Fix issue with locals overlapping out of scope GCFrame

More aggressive C/C++ optimizations done by VS2019 are breaking fragile
assumptions of the CoreCLR "manually managed code".

Unwinding of Frame chains accesses stack local variables after the stack
frame has been unwound, but it depends on their content to be left
intact. The new compiler is breaking this assumption by stack-packing a
different variable over it.

This change fixes the problem by adding a destructor to GCFrame that
pops the frame from the per-thread Frame list.

I also had to refactor two functions where the compiler was complaining
about mixing SEH and C++ EH in single function.

With these changes applied, there was still a problem that I've discovered
when running CoreCLR tests with GCStress 3. When the
ExceptionTracker::m_pInitialExplicitFrame was still pointing to a frame
that was already removed from the explicit Frame chain. When the
ExceptionTracker::HasFrameBeenUnwoundByAnyActiveException was walking
the frame chain starting at m_pInitialExplicitFrame to figure out if a given
frame was already unwound, it has walked to the destroyed GCFrame and
crashed.

To fix that, the chain from the initial explicit frame is updated so
that it stays valid (effectively, the destroyed GCFrame is removed from
it). It was also necessary to handle the case when the destroyed GCFrame
was the ExceptionTracker::m_pLimitFrame. The limit frame needs to be
updated to the next frame so that it can be reached on the chain from
the initial explicit frame.

* Reflect PR feedback

Change the switching to coop mode in ~GCFrame from holder based to
manual.
