spec: clarify rules for type set construction of an interface

2022-04-19T23:42:38+00:00

Be explicit that we always mean non-interface types when we
talk about sets of types.

Also, clarify that the quantification "all non-interface types"
means all such types in all possible programs, not just the
current program.

Per suggestion from Philip Wadler.

doc/go1.19: move the description of the runtime.GOROOT change from 'cmd/go' to 'runtime'

2022-04-19T16:24:48+00:00

Even though the change in the behavior of 'runtime.GOROOT' was
not actually due to a change in the runtime package proper, I
suspect that users who notice it will look for the release note
in that section, not the 'cmd/go' section.

Fixes #51461.

image/draw: have draw.Src preserve NRGBA colors

2022-04-07T10:41:34+00:00

This reverts a behavior change introduced in Go 1.18 (commit 9f69a443;
CL 340049). In Go 1.17 and earlier, draw.Draw(etc, draw.Src) with
image.NRGBA dst and src images would pass through a (heap allocated)
color.Color interface value holding a color.NRGBA concrete value.
Threading that color.NRGBA value all the way through preserves
non-premultiplied alpha transparency information (distinguishing e.g.
transparent blue from transparent red).

CL 340049 optimized out that heap allocation (per pixel), calling new
SetRGBA64At and RGBA64At methods instead. However, these methods (like
the existing image/color Color.RGBA method) work in premultiplied alpha,
so any distinction between transparent colors is lost.

This commit re-introduces the preservation of distinct transparencies,
when dst and src are both *image.NRGBA (or both *image.NRGBA64) and the
op is draw.Src.

Fixes #51893

doc/go_spec.html: update type identity example

2022-04-04T21:36:50+00:00

In the Type identity section, the example provides various types as givens.

The example refers to the type *T5, but it is not provided in the givens.

I am assuming this was a typo, and was meant to refer to *A1 or *B1.
*B1 seems to be in alignment with the rest of the provided examples.

doc: add illegal octal over 255 example

2022-04-02T17:45:45+00:00

Octal values over 255, like \400 or \777, are illegal.  It wasn't clear if the expected behavior was a compile error, encoding the value as two characters, or if the value would be capped at 255.

This example explicitly shows that octal values over 255 are illegal.
