Bruce Forstall [Tue, 7 May 2019 18:06:28 +0000 (11:06 -0700)]
Fix build.cmd passing of args to runtest.cmd

If you use the `generatelayout` argument to build.cmd, it passes
all "unprocessed" arguments directly on to msbuild. To accomplish
the same this with runtest.cmd, you must use the "msbuildargs"
argument, or else the arg will be treated as a `CORE_ROOT` argument.
(This seems like a bad design, but that's a separate issue.)

E.g., I always pass `/consoleloggerparameters:ForceNoAlign`, and want
that passed on to runtest.cmd. (This should also be the default, but
once again, that's a separate issue.)

5 years agoSupport for larger version bubbles in R2RDump (dotnet/coreclr#24277)
Tomáš Rylek [Tue, 30 Apr 2019 21:16:46 +0000 (23:16 +0200)]
Support for larger version bubbles in R2RDump (dotnet/coreclr#24277)

After JanV fixed basically all test failures related to larger
version bubbles originally implemented by Andon, it's high time
to fix R2RDump for its support as a prerequisite to enabling
larger version bubbles in CPAOT. This change implements this
support via the following particular changes:

1) In DumpOptions, I added a list of explicit assembly references,
another list of reference paths that are used for resolving
assembly references, a cache for repeated assembly lookups and
a new method FindAssembly for file resolution of a given simple
assembly name.

2) I have moved ECMA metadata-related logic from R2RReader to
its new base class EcmaMetadataReader. This class can represent
both R2R and MSIL binaries and adds the logic for reference
assembly lookup.

3) Large version bubble R2R PE exe's contain a special R2R header
table READYTORUN_SECTION_MANIFEST_METADATA that contains ECMA
metadata with a list of extra AssemblyRef's on top of those stored
in the original MSIL. I have added support for parsing this table
to the R2RReader constructor.

4) I have modified R2RSignature to be based off the new
EcmaMetadataReader instead of R2RReader which cannot represent
arbitrary reference assemblies. I have patched the two places
dealing with module overrides to use the new logic to temporarily
switch to a "remote module" SignatureDecoder for the purpose
of parsing an external entity.

5) I have removed temporary hacks Andon put in place to keep
R2RDump alive in some cases with larger version bubbles without
proper support for parsing module overrides.

6) I have added logic for dumping the contents of the manifest
metadata along with the standard AssemblyRef table to the
header dump as I fought with recalculation of the indices
when debugging larger version bubble code for quite some time.

7) As an extra half-forgotten bit from the past I added dumping
of unboxing and instantiation stubs.

I have noticed that the MSIL AssemblyRef count was off by one.
I have also found out that XML output has bitrotten over time.
This additional delta fixes both issues. [That forced me to
add a bunch of empty ctors even though in practice we don't
actually serialize anything into the dumper, we only use
the XML serializer to emit the XML output file.

Thanks

Tomas

* Suppress duplicate types in System.Resources.Binary.*

* Test refactoring and adding RuntimeResourceSet

It turns out me must have our own ResourceSet since the CoreLib resource set doesn't
expose a constructor that takes an IResourceReader.

I've shared the code since it does a bit of non-trivial caching.

* Don't use auto-property initializers for platfrom sensitive test data

For some reason I thought these lazy-initialized the properties but they don't.

As a result we were hitting the platform sensitive code even when we never
called the getter.  Switch to an expression instead.

* Only use Drawing converters on Windows

* Fix test failures

* Don't leak System.Private.CoreLib into resources

* Ensure we have stable type names in Resources.Extensions

We don't want to use the runtime type identity when doing type checks or writing
types as this may change.  Instead, check-in hard-coded strings that match the
type identity.

Add a test case to ensure the resources we generate match what we
test the reader against in the resource manager case (also to track any

5 years agoImprove LOH heap balancing (dotnet/coreclr#24081)
Andy Hanson [Sat, 27 Apr 2019 02:33:26 +0000 (19:33 -0700)]
Improve LOH heap balancing (dotnet/coreclr#24081)

* Improve LOH heap balancing

Previously in `balance_heaps_loh`, we would default to `org_hp` being
`acontext->get_alloc_heap()`.

Since `alloc_large_object` is an instance method, that ultimately came
from the heap instance this was called on. In `GCHeap::Alloc` that came
from `acontext->get_alloc_heap()` (this is a different acontext). That
variable is set when we allocate a small object. So the heap we were
allocating large objects on was affected by the heap we were allocating
small objects on. This isn't necessary as small object heap and large
object heaps have separate areas. In scenarios with limited memory, we
can unnecessarily run out of memory by refusing to move away from that
hea. However, we do want to ensure that the large object heap accessed
is not on a different numa node than the small object heap.

I experimented with adding a `get_loh_alloc_heap()` to acontext similar
to the SOH alloc heap, but performance tests showed that it was usually
better to just start from the home heap. The chosen policy was:

* Start searching from the home heap -- this is the one corresponding to
our processor.

* Have a low (but non-zero) preference for that heap (dd_min_size(dd) /
2), as long as we stay within the same numa node.

* Have a higher cost of switching to a different numa node. However,
this is still much less than before; it was dd_min_size(dd) * 4, now
dd_min_size(dd) * 3 / 2.

This showed big performance improvements (over 30% less time) in a
scenario with lots of LOH allocation where there were fewer allocating
threads than GC heaps. The changes were more pronounced the more we
allocated large objects vs small objects. There was usually slight
improvement (1-2%) when there were 48 constantly allocating threads and
48 heaps. The one place we did see a slight regression was in an 800MB
container and 4 allocating threads on a 48 processor machine; however,
similar tests with less memory or more threads were prone to running out
of memory or running very slow on the master branch, so we've improved
stability. Previously the gc could get lucky by having the SOH choice
happen to be a good choice for LOH, but we shouldn't be relying on it as
it failed in some container scenarios.

One more change is in joined_generation_to_condemn: If there is a memory
limit and we are about to OOM, we should always do a compacting GC. This
helps avoid the OOM and feeds into the next change.

This PR also adds a *second* balance_heaps_loh function for when there
is a memory limit and we previously failed to allocate into the chosen
heap. `balance_heaps_loh` works based on allocation budgets, whereas
`balance_heaps_loh_hard_limit_retry` works on the actual space available
at the end of the segment. Thanks to the change to
joined_generation_to_condemn the heaps should be compact, so not looking
at free space here.

* Fix uninitialized variable

* In a container, use space available instead of budget

* Fix duplicate semicolon

Clean up fgRemoveDeadStore.

Remove duplication and a couple of goto's from `fgRemoveDeadStore`.

                    }
                }
`

The `goto` was to the preceding `if` and was useless since the call
to `gtExtractSideEffList(rhsNode, &sideEffList);` couldn't possibly find
side effects because we already checked that
`rhsNode->gtFlags & GTF_SIDE_EFFECT == 0`.

Fix for a jit liveness bug.

`fgRemoveDeadStore` has special logic for removing dead assignments

assignments (i.e., direct children of `GT_STMT`) but not to "internal"
assignments (e.g., children of `GT_COMMA`).
The test case has an internal assignment and, because this logic wasn't
applied, we ended up with a standalone `GT_IND` of type `TYP_STRUCT`
that the register allocator can't handle.

This change apples the missing logic to "internal" assignments.

* Fixing 23941

The issue here is that in R2R code, unlike jitted IL code, the pinvoke calls are wrapped by a pair of calls to the JIT_PInvokeBegin and JIT_PInvokeEnd helpers, which link and unlink the InlinedCallFrame to the current thread. We do not initialize and link the ICF in the method prolog, and unlink it in the epilog, like jitted code does. We do this in the JIT helpers, right before/after the pinvoke call.
When an exception is thrown, the JIT_PInvokeEnd helper will be skipped since execution will resume at the nearest valid catch block, and the ICF will remain linked to the thread, which poses a problem if the method attempts another pinvoke operation (it will try to link the ICF which is already the top frame, and we'll end up in an infinite loop). Therefore, for the R2R case, we need to pop the ICF from the chain during exception unwinding.

Fix NUMA node for heap when NUMA is not available

The recent refactoring of the GCToOSInterface::GetProcessorForHeap has
accidentally changed the NUMA node returned in case NUMA is disabled
(either via the COMPlus_GCNumaAware or due to the fact that there is
just a single NUMA node on the system) and the CPU groups are disabled.
Before that refactoring, the code was incorrectly returning 0 as the
NUMA node when CPU groups were disabled no matter whether NUMA was
enabled or disabled. The refactoring fixed that by returning the
current CPU group number for the case when NUMA was enabled, however
it still returned incorrect value, this time GroupProcNo::NoGroup as
the NUMA node number in case NUMA was disabled.

This change fixes it by returning the current group number in this case.

Right now, if the user sets the configuration so that the server GC is
used, the server GC will be loaded even in conditions where we know the
workstation GC would fare better. An example of such conditions is
constrained environment where there is only 1 or less CPU or with very
low memory.

This can be harmful if users deploy the same projects on different kind
of platforms: deploying to a 20+ cores server and to Azure Functions
will require largely different configurations for the runtime.

There are already multiple ways for the user to specify to use the
server GC or not:
 - setting `COMPlus_gcServer` as an environment variable
 - setting `gcServer` in the configuration file
 - setting `System.GC.Server` passed to `coreclr_initialize`

Do the work in src/vm/ceemain.cpp otherwise there will be a disparity
between what the VM and the GC are running. Before, only the GC would be
aware of the switch from server to workstation GC, but not the VM.
