so that it waits until online check syntax actually
finishes (otherwise, there actually is a leak;
the link is broken when the message comes back from the
other place)
This tracking allows the compiler to treat structure sub-type
declarations as generating constant results, and it also allows
the compiler to recognize an applications of a constructor or
predicate as functional.
The JIT takes advantage of known-constant bindings to avoid the
check that a variable is still bound to a structure predicate,
selector, or mutator; that makes the code short enough to really
inline. The inlined version takes about half the time of the
indirect version.
The compiler does not yet track bindings precisely enough to
recognize constants for sub-type declarations.
- lets other events be handled based on how long it has been
replaying the current trace (instead of based on the number of
pieces in the trace that have been seen)
- breaks up the syncheck:add-rename-menu pieces of the trace to
be more granular (to make the previous point work better)
This should make DrRacket more responsive when the trace is being
replayed
This fixes several issues:
- `Parameter` generates impersonator contracts correctly
- `Any` handling now copies immutable data when possible
- `Any` now recognizes more atomic base types
Merge to 5.3.1.
This reverts commit d39780a130.
Matthew says this test is really about TCP, so it should not be
changed. Although perhaps we can use a more basic TCP test to check if
this should be done.
so that no derivation data structure creation
happens during just a normal judgment-holds,
but this was not entirely successful, so there
still is some....
Also, improved the test-util to show stacktraces
for errors (when they exist)
Turn use of a finalized ffi callout into a reported error,
instead of a crash. Clarify the existence of the finalizer
in the docs. Fix error logging of the finalizer thread.
Merge to v5.3.1
