886fba5871 crypto/ecdsa: properly truncate P-521 hashes
Before, if a hash was exactly 66 bytes long, we weren't truncating it
for use with P-521, because the byte length was not overflowing.
However, the bit length could still overflow.

a datagram socket and instead properly construct net.UDPConn values

f7e11723e5 cmd/dist: do not use user build cache in versioned trees
There is no guarantee that the user build cache will have
correct data if we are using a versioned build (with a VERSION file),
because that overrides the use of tool build IDs for staleness.
An earlier build might have run with a buggy compiler, and we don't
want those files lying around.

962753b015 go/build: check for invalid import paths again
The go parser previously checked for invalid import paths, go/build,
seeing the parse error would put files with invalid import paths into
InvalidGoFiles. golang.org/cl/424855 removed that check from the
parser, which meant files with invalid import paths not have any parse
errors on them and not be put into InvalidGoFiles. Do a check for
invalid import paths in go/build soon after parsing so we can make
sure files with invalid import paths go into InvalidGoFiles.

This fixes an issue where the Go command assumed that if a file wasn't
invalid it had non empty import paths, leading to a panic.

3367475e83 go/types, types2: use correct reverse inference approach
To infer type arguments in an assignment of the form

        var target func(t1, t2, ...) = g

where g is a generic function

        func g[P1, P2, ...](p1, p2, ...)

the type checker used the synthetic function call

        g(t1, t2, ...)

But because each argument (of type) t1, t2, ... is assigned to its
corresponding parameter p1, p2, ..., type inference uses assignment
rules ("inexact match") for unification.

As a result, types such as mystring and string match even though
they should not (they are not identical), yet function parameter
types must be identical to match.

This CL fixes this by constructing the synthetic call

        g'(func(t1, t2, ...))

where g' is the generic function

        func g'[P1, P2, ...](func(p1, p2, ...))

This mimics the function assignment directly by representing it as
a single argument passing (of a function-typed argument). Function
parameter types must now be identical to unify.

As an added benefit, the implementation is simpler.

As a consequence, when such an assignment is invalid because the
function types cannot possibly match, we now correctly get an
inference error. Without this change, in some cases unification
would succeed, only to lead to an assignment error afterwards.

While at it, update the date in the copyright notice of
testdata/manual.go so we don't need to fix it each time we copy
code from a test case in manual.go into a issueXXXXX.go file.

Fixes #60688.

f35d2dae74 go/types, types2: use inexact unification when unifying against core types
Follow-up on CL 498955 which introduced a unification mode, to be used
to control the precision of unification of element types (CL 498895):
When unifying against core types of unbound type parameters, we must
use inexact unification at the top (irrespective of the unification mode),
otherwise it may fail when unifying against a defined type (core types
are always underlying types).

No specific test case (I have not been able to create one yet).

When determining DepsErrors for packages, we were trying to sort
errors by the top package on their ImportStack (which would likely be
the package the error was generated for) to get a deterministic
error order.

The problem is that some PackageErrors don't have ImportStacks set on
them. Fall back to sorting the errors by the error text (instead of
making things more complicated by tracking the packages that produced
the errors more closely).

7b325ba27d runtime: apply looser bound to /gc/heap/live:bytes in test
/gc/heap/live:bytes may exceed MemStats.HeapAlloc, even when all data is
flushed, becuase the GC may double-count objects when marking them. This
is an intentional design choice that is largely inconsequential. The
runtime is already robust to it, and the condition is rare.

Fixes #60607.

fd13444b2b go/types: fix method set computation if receiver is a named pointer
Per the spec, methods cannot be associated with a named pointer type.
Exit early with an empty method set in this case.

This matches the corresponding check in LookupFieldOrMethod;
the check is not present in (lowercase) lookupFieldOrMethod
because it (the check) doesn't apply to struct fields.
