9c5eb16f6c net: reduce allocation size in ReadFromUDP
Switch to concrete types. Bring your own object to fill in.

Allocate just enough for the IP byte slice.
The allocation is now just 4 bytes for IPv4,
which puts it in the tiny allocator, which is much faster.

0e7a7a68cd text/template/parse: rename DeferFuncCheck to SkipFuncCheck
The proposal as accepted in #34652 named the bit SkipFuncCheck.
It was renamed to DeferFuncCheck during the code review on a suggestion by Rob,
along with a comment to “defer type checking functions until template is executed,”
but this description is not accurate: the package has never type-checked functions,
only verified their existence. And the effect of the bit in this package is to eliminate
this check entirely, not to defer it to some later time.

I was writing code using this new bit and was very confused about when the
"type checking" was being deferred to and how to stop that entirely,
since in my use case I wanted no checks at all. What I wanted is what the bit does,
it just wasn't named accurately.

Rename back to SkipFuncCheck.

3498027329 math: increase precision of math.SmallestNonzeroFloat64
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.

Fixes #44058.

corrupting their memory every time they used it. Either that memory

6f264801a7 go/printer: remove exported StdFormat flag
The StdFormat flag was added as part of CL 231461, where the primary aim
was to fix the bug #37476. It's expected that the existing printer modes
only adjust spacing but do not change any of the code text itself. A new
printing flag served as a way for cmd/gofmt and go/format to delegate
a part of formatting work to the printer—where it's more more convenient
and efficient to perform—while maintaining current low-level printing
behavior of go/printer unmodified.

We already have cmd/gofmt and the go/format API that implement standard
formatting of Go source code, so there isn't a need to expose StdFormat
flag to the world, as it can only cause confusion.

Consider that to format source in canonical gofmt style completely it
may require tasks A, B, C to be done. In one version of Go, the printer
may do both A and B, while cmd/gofmt and go/format will do the remaining
task C. In another version, the printer may take on doing just A, while
cmd/gofmt and go/format will perform B and C. This makes it hard to add
a gofmt-like mode to the printer without compromising on above fluidity.

This change prefers to shift back some complexity to the implementation
of the standard library, allowing us to avoid creating the new exported
printing flag just for the internal needs of gofmt and go/format today.

We may still want to re-think the API and consider if something better
should be added, but unfortunately there isn't time for Go 1.15. We are
not adding new APIs now, so we can defer this decision until Go 1.16 or
later, when there is more time.

For #37476.
For #37453.
For #39489.
For #37419.

6e592c2b6d go/types: unexport Checker.LookupFieldOrMethod
Implementation changes in go/types for #6977 required that internal
LookupFieldOrMethod calls had access to the current *Checker. In
order to make quick progress, I added a *Checker receiver to the
function LookupFieldOrMethod (thus making it a method), and added
a new function LookupFieldOrMethod. The plan was always to rename
that function (Checker.LookupFieldOrMethod) such that it wouldn't
be exported; with the obvious name being Checker.lookupFieldOrMethod.
But that name was already in use which is why I postponed the rename.
Eventually I forgot to clean it up. This CL fixes that with the
following renames:

Checker.lookupFieldOrMethod => Checker.rawLookupFieldOrMethod
Checker.LookupFieldOrMethod => Checker.lookupFieldOrMethod

Updates #6977.
Fixes #36916.

ea8b0acdac all: remove os.ErrTemporary
As discussed in
https://github.com/golang/go/issues/32463#issuecomment-506833421
the classification of deadline-based timeouts as "temporary" errors is a
historical accident. I/O timeouts used to be duration-based, so they
really were temporary--retrying a timed-out operation could succeed. Now
that they're deadline-based, timeouts aren't temporary unless you reset
the deadline.

Drop ErrTemporary from Go 1.13, since its definition is wrong. We'll
consider putting it back in Go 1.14 with a clear definition and
deprecate net.OpError.Temporary.

also accepts the new number literals including separators with the
various conversion routines, if no explicit number base is given.

34fb5855eb text/scanner: don't liberally consume (invalid) floats or underbars
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.
