This change does three things.

First, it fixes `GetSubArray` to work when the supplied array is actually a `U[]` where `U : T`.  Currently this case ends up throwing an exception inside of span, which doesn't like working with arrays covariantly.

Second, it fixes argument validation so that we throw an ArgumentNullException if the input array is null rather than NullReferenceException.

Third, it improves the performance of `GetSubArray` for the 95% common case where either `T` is a value type or the type of the array matches the `T` type specified.

5 years agoDon't null out references in Stream/BinaryReader/Writer (#23725)
Stephen Toub [Fri, 5 Apr 2019 18:30:28 +0000 (14:30 -0400)]
Don't null out references in Stream/BinaryReader/Writer (#23725)

These types null out some fields on Dispose, and some of those fields are accessible directly via exposed properties, which means that nulling them out would either force us to annotate those properties as being nullable or would require us to lie about them being nullable.  Nulling them out also makes it easier to accidentally null ref in the implementation, and prevents us from making the fields readonly.

It should be exceedingly rare that you dispose of one of these objects and then keep it alive while also being concerned about keeping alive the other helper objects the type uses.  So this change just uses a separate flag to track disposal, and avoids nulling out the fields, which is not a common practice elsewhere in the framework.

This will be a visible change in that after Dispose, properties like StreamWriter.BaseStream/Encoding will now return the stream/encoding rather than null.  In theory that could break someone if they were using those properties to determine whether the writer had been disposed, but that seems unlikely / similar fallout from most any bug fix, and objects generally aren't supposed to be touched after Dispose, anyway.

5 years agoPartially improve support for `--cpus` from Docker CLI (#23747)
Ludovic Henry [Fri, 5 Apr 2019 16:42:47 +0000 (09:42 -0700)]
Partially improve support for `--cpus` from Docker CLI (#23747)

* Round up the value of the CPU limit

In the case where `--cpus` is set to a value very close to the smaller
integer (ex: 1.499999999), it would previously be rounded down. This
would mean that the runtime would only try to take advantage of 1 CPU in
this example, leading to underutilization.

By rounding it up, we augment the pressure on the OS threads scheduler,
but even in the worst case scenario (`--cpus=1.000000001` previously
being rounded to 1, now rounded to 2), we do not observe any
overutilization of the CPU leading to performance degradation.

* Teach the ThreadPool of CPU limits

By making sure we do take the CPU limits into account when computing the
CPU busy time, we ensure we do not have the various heuristic of the
threadpool competing with each other: one trying to allocate more
threads to increase the CPU busy time, and the other one trying to
allocate less threads because there adding more doesn't improve the
throughput.

Let's take the example of a system with 20 cores, and a docker container
with `--cpus=2`. It would mean the total CPU usage of the machine is
2000%, while the CPU limit is 200%. Because the OS scheduler would never
allocate more than 200% of its total CPU budget to the docker container,
the CPU busy time would never get over 200%. From `PAL_GetCpuBusyTime`,
this would indicate that we threadpool threads are mostly doing non-CPU
bound work, meaning we could launch more threads.
