math: increase precision of math.SmallestNonzeroFloat64

2021-04-30T00:13:38+00:00

The original value was rounded too early, which lead to the
surprising behavior that float64(math.SmallestNonzeroFloat64 / 2)
wasn't 0. That is, the exact compile-time computation of
math.SmallestNonzeroFloat64 / 2 resulted in a value that was
rounded up when converting to float64. To address this, added 3
more digits to the mantissa, ending in a 0.

While at it, also slightly increased the precision of MaxFloat64
to end in a 0.

Computed exact values via https://play.golang.org/p/yt4KTpIx_wP.

Added a test to verify expected behavior.

In contrast to the other (irrational) constants, expanding these
extreme values to more digits is unlikely to be important as they
are not going to appear in numeric computations except for tests
verifying their correctness (as is the case here).

Re-enabled a disabled test in go/types and types2.

Updates #44057.
Fixes #44058.

syscall: restore broken GetQueuedCompletionStatus signature but make it not crash

2021-02-24T23:35:00+00:00

This reverts commit dc4698f52b5ad3f0251e0cc25bc7ffbd10e23f2c, and then
fixes the memory corruption issue. It also suggests users switch to
x/sys/windows for the proper function.

This requires CL 295174 to be submitted first.

Updates #44538.

syscall: do not overflow key memory in GetQueuedCompletionStatus

2021-02-24T18:03:45+00:00

The third argument to GetQueuedCompletionStatus is a pointer to a
uintptr, not a uint32. Users of this functions have therefore been
corrupting their memory every time they used it. Either that memory
corruption was silent (dangerous), or their programs didn't work so they
chose a different API to use.

Fixes #44538.

text/scanner: don't liberally consume (invalid) floats or underbars

2019-02-20T20:23:28+00:00

This is a follow-up on https://golang.org/cl/161199 which introduced
the new Go 2 number literals to text/scanner.

That change introduced a bug by allowing decimal and hexadecimal floats
to be consumed even if the scanner was not configured to accept floats.

This CL changes the code to not consume a radix dot '.' or exponent
unless the scanner is configured to accept floats.

This CL also introduces a new mode "AllowNumberbars" which controls
whether underbars '_' are permitted as digit separators in numbers
or not.

There is a possibility that we may need to refine text/scanner
further (e.g., the Float mode now includes hexadecimal floats
which it didn't recognize before). We're very early in the cycle,
so let's see how it goes.
