c5463218a2 cmd/api: skip TestIssue29837 when -short is set
TestIssue29837 takes a long time to run, ~150s on my laptop
and ~40s on CI builders.

While here, warm up the go list cache in parallel, which reduces the
test time by ~10%.

9fc84363d1 cmd/asm: fix encoding errors for FMOVD and FMOVS instructions on arm64
The encoding of instructions "FMOVD F1, ZR" and "FMOVS F1, ZR" is wrong,
the assembler encodes them as "FMOVD F1, F31" and "FMOVS F1, F31". This
CL fixes the bug.

3aea422e2c crypto/x509: use synthetic root for platform testing
Rather than using the external network and real-world chains for testing
the integrations with platform verifiers, use a synthetic test root.

This changes adds a constrained root and key pair to the tree, and adds
a test suite that verifies certificates issued from that root. These
tests are only executed if the root is detected in the trust store. For
reference, the script used to generate the root and key is attached to
the bottom of this commit message.

This change leaves the existing windows/darwin TestPlatformVerifier
tests in place, since the trybots do not currently have the test root in
place, and as such cannot run the suite. Once the builder images have
the root integrated, we can remove the old flaky tests, and the trybots
will begin running the new suite automatically.

Updates #52108

0a48e5cbfa slices: consistently use S ~[]E
Make all functions use a constraint S ~[]E even if they don't return
the slice type. This makes explicitly instantiating the functions more
consistent: you don't have to remember which take ~[]E and which do not.
It also permits inferring the type when passing one of these functions
to some other function that is using a named slice type.

Fixes #60546

c3db64c0f4 net: fix panic when calling net.Listen or net.Dial on wasip1
Address a panic that was caused by net.Dial/net.Listen entering the fake
network stack and assuming that the addresses would be of type *TCPAddr,
where in fact they could have been *UDPAddr or *UnixAddr as well.

The fix consist in implementing the fake network facility for udp and
unix addresses, preventing the assumed type assertion to TCPAddr from
triggering a panic. New tests are added to verify that using the fake
network from the exported functions of the net package satisfies the
minimal requirement of being able to create a listener and establish a
connection for all the supported network types.

70cb990b15 database/sql: fix flake in TestContextCancelDuringRawBytesScan

allowing this case.

The old flake reproduced easily with:

	go test -c
	stress ./sql.test -test.count=100 -test.run=TestContextCancelDuringRawBytesScan

The new test modes exercise that path directly instead of needing stress.

The new check for context.Canceled fixes the new test mode "top".

ccf75b36ff cmd/internal/obj: make aix/ppc64 builds reproducible
sort.Slice was being used to sort some newly added entries by name
to make the ctxt.Data slice reproducible, but some existing entries
have the same name, and the effect was to take the non-determinism
of the tail entries and scatter it into the earlier, deterministic section
when multiple entries had the same name.

The specific entries with the same name are type SDWARFVAR, which
all have an empty name but different relocations. If they are shuffled,
then the relocation symbols are visited in a different order, which
enters them into the string table in a different order, which results in
different object files, different object file hashes, and different build IDs
for the final executables.

Use sort.SliceStable to avoid reordering entries we don't mean to reorder.

Also add a simple test for scheduling-related non-determinism.
I debugged this originally using 'go install -race cmd/compile',
but that was slow and turned out not to be terribly reliable.
Using a few different GOMAXPROCS settings turns out to be a much more
effective (and faster) way to scramble scheduling decisions.

Fixes #60759.

The WASI specification has file types for both stream and datagram
sockets. This change refactors the internal implementation of the
net.FileConn and net.FileListener functions to avoid returning a
misleading ENOTSOCK when calling net.FileConn with a file referencing
a datagram socket and instead properly construct net.UDPConn values
or return EOPNOTSUPP otherwise.

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).

the package the error was generated for) to get a deterministic

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).
