cmd/dist: do not include runtime/internal/sys in cmd staleness checks
Since CL 454836, cmd/dist has built the packages in 'cmd' with different settings than those in 'std': namely, for' cmd' we disable the use of cgo, and (since CL 463740) if GO_BUILDER_NAME is non-empty or the VERSION file indicates a release version we also set GOFLAGS=-trimpath. However, since at least CL 73212 the staleness checks performed by cmd/dist for the “toolchain” targets (a subset of 'cmd') have included the package "runtime/internal/sys" (which is in 'std', not 'cmd'). At that time, cmd/go did not have a separate build cache, so it would not have been possible to check staleness for a 'cmd' build differently from 'std'. However, now that is possible, and most of the time "runtime/internal/sys" lives *only* in the build cache (and so is essentially never stale after building anything that imports it). But there is one more wrinkle: if GODEBUG=installgoroot=all is set, the packages in 'std' are still installed to GOROOT/pkg, and can once again become stale. Since the install with the 'std' configuration does not match the configuration used to build 'cmd', the staleness check fails for "runtime/internal/sys" under the 'cmd' configuration. Since we intentionally build the toolchain with a different "runtime/internal/sys" stored only in the build cache, there is no longer a point in checking that package for staleness: if it is stale, then the toolchain itself will be reported as stale anyway. So we can simply remove the package from that staleness check, and unbreak bootstrapping with GODEBUG=installgoroot=all. I tested this manually using the sequence: export GODEBUG=installgoroot=all export GO_BUILDER_NAME=linux-amd64-bcmills ./make.bash It fails the staleness check before this change, and successfully builds after. For #24904.

cmd/go/internal/par: use generic Cache
Using generics here makes the code easier to understand, as the contract is clearly specified. It also makes the code a little more concise, as it's easy to write a wrapper for the cache that adds an error value, meaning that a bunch of auxilliary types no longer need to be defined for this common case. The load.cachingRepo code has been changed to use a separate cache for each key-value type combination, which seems a bit less sleazy, but might have some knock-on effect on memory usage, and could easily be changed back if desired. Because there's no longer an unambiguous way to find out whether there's an entry in the cache, the Cache.Get method now returns a bool as well as the value itself.

go/types, types2: implement simpler type inference (infer2)
This change implements infer2 which is a drop-in replacement for
infer; it can be enabled by setting the useNewTypeInference flag
in infer2.go. It is currently disabled (but tested manually).
infer2 uses the same machinery like infer but in a simpler approach
that is more amenable to precise description and future extensions.
The goal of type inference is to determine a set of (missing) type
arguments from a set of other given facts. Currently, these other
facts are function arguments and type constraints.
In the following, when we refer to "type parameters", we mean the
type parameters defined by the generic function to which we apply
type inference. More precisely, in the algorithm, these are the
type parameters recorded with the unifier.
The approach is as follows:
- A single unifier is set up which tracks all type parameters and
corresponding inferred types.
- The unifier is then fed all the facts we have. The order is not
relevant (*) except that we use default types of untyped constant
arguments only as a last resort, at the end.
- We start with all function arguments: for each generic function
parameter with a typed function argument, we unify the parameter
and function type.
- We then unify each type parameter with its type constraint.
This step is iterated until nothing changes anymore, because
each unification may enable further unification.
- If there are any type parameters left without inferred types,
and which are used as function parameters with untyped constant
arguments, unify them with the default types of those arguments.
Because of unification with constraints which themselves may contain
type parameters, inferred types may contain type parameters. Thus,
in a final step we substitute type parameters for their inferred types
until there are no type parameters left in the inferred types.
All these individual steps are the same as in infer, but there is no
need to do constraint type inference twice (all the facts have already
been used for inference). Also, we only need a single unifier which
serves as the holder for the inferred type parameter types.
Type inference fails if any unification step fails or if not all
type arguments could be inferred. By always using all available
facts (**) we ensure that order doesn't matter.
By using more facts, type inference can now be extended to become
more powerful.
The code can be split up into smaller components that are more
easily digestable. Because we forsee more simplifications, we
defer such cleanups to later CLs.
(*) We currently have a sorting phase in the beginning such that
function argument types that are named types are used before
any other type. We believe this step can be eliminated by
modifying the unifier slightly.
(**) When unifying constraints, in some cases we don't report
an error if unification fails. We believe we can modify the
unifier and then consistently report an inference failure
in this case as well.

cmd/go/internal/test: scale the WaitDelay for test subprocesses
Prior to CL 456116 we had an arbitrary 5-second delay after a test times out before we kill the test. In CL 456116, I reused that arbitrary 5-second delay as the WaitDelay as well, but on slower builders it does not seem to be generous enough. Instead of hard-coding the delay, for tests with a finite timout we now use a hard-coded fraction of the overall timeout. That will probably give delays that are longer than strictly necessary for very long timeouts, but if the user is willing to wait for a very long timeout they can probably wait a little longer for I/O too. Fixes #58230. Updates #24050.

runtime: eliminate arbitrary timeout in TestCgoLockOSThreadExit
This test previously failed if running a new pthread took longer than a hard-coded 100ms. On some slow or heavily-loaded builders, that scheduling latency is too short. Since the point of this test is to verify that the background thread is not reused after it terminates (see #20395), the arbitrary time limit does not seem helpful: if the background thread fails to terminate the test will time out on its own, and if the main goroutine is scheduled on the background thread the test will fail regardless of how long it takes.

internal/testenv: avoid rebuilding all of std in WriteImportcfg
Instead, have the caller pass in an explicit list of the packages (if any) they need. After #47257, a builder running a test does not necessarily have the entire standard library already cached, especially when running tests in sharded mode. testenv.WriteImportcfg used to write an importcfg for the entire standard library — which required rebuilding the entire standard library — even though most tests need only a tiny subset. This reduces the time to test internal/abi with a cold build cache on my workstation from ~16s to ~0.05s. It somewhat increases the time for 'go test go/internal/gcimporter' with a cold cache, from ~43s to ~54s, presumably due to decreased parallelism in rebuilding the standard library and increased overhead in re-resolving the import map. However, 'go test -short' running time remains stable (~5.5s before and after). Fixes #58248.

net/netip: fix invalid representation of Prefix
For a given Addr, ensure there is exactly one invalid representation. This allows invalid representations to be safely comparable. To ensure that the zero value of Prefix is invalid, we modify the encoding of bits to simply be the bit count plus one. Since Addr is immutable, we check in the PrefixFrom constructor that the provided Addr is valid and only store a non-zero bits length if so. IsValid is simplified to just checking whether bitsPlusOne is non-zero.

go/types, types2: replace unifier type parameter list with a map
Further simplify the unifier by using a mapping from type parameter to type (argument) handle, where a handle is just an indirection to the actual type associated with the type parameter. If multiple type parameters are "joined", i.e., share the same type (argument), then they use the same handle. Thus, if one of the type parameters gets a type, all type parameters sharing the same handle get the same type. The handles mapping replaces the indices list (mapping from type parameter index to types index). Because each handle holds any associated type directly, we also don't need a types list anymore. We still keep the incoming type parameter list to maintain the same order for printing and reporting inferred types. We may be able to eliminate this list as well in future CLs.

For #58166, this has the effect of pushing the induction variable increment to the end of the block, past all the other uses of the pre-incremented value. Do this only with optimizations on. Debuggers have a preference for values in source code order, which this CL can degrade.

crypto/rand: batch large random reads on js
CL 463975 replaced the use of the NodeJS crypto.randomFillSync API with a direct call to crypto.getRandomValues. This function rejects any requests to fill a buffer larger than 65536 bytes, so we need to batch reads larger than this size. This reuses the batching functions used on other platforms to perform this batching.

cmd/dist, internal/platform: remove some target modes that fail
Before CL 463992 there were some cases that cmd/dist did not test
but that platform.BuildModeSupport permitted. In CL 463992 those
conflicts were resolved in favor of platform.BuildModeSupport.
However, further testing has uncovered some cases that do not in
fact work. Adjust those in both cmd/dist and internal/platform.
In particular, mark android-arm and android-arm64 as not supporting
plugin mode. Sample failure:
https://build.golang.org/log/ebba858ea9f94f076966d8cfd42348a0e9345095

runtime: always use LoadLibraryEx to load system libraries
This CL removes a fallback that used LoadLibraryA when the runtime
was loading system DLLs on Windows 7, Windows Server 2008 R2,
or earlier.
We can safely remove that fallback now, as go1.21 will require at least
Windows 8 or Server 2012.
This CL also saves some syscall initialization time and bytes:
new:
init syscall @2.3 ms, 0 ms clock, 1000 bytes, 18 allocs

cmd/go: traverse module-root symlinks in Walk calls
fsys.Walk, like filepath.Walk, avoids traversing symlinks. Also like filepath.Walk, it follows a symlink at the root if the root path ends in a file separator (consistent with POSIX pathname resolution¹). If the user's working directory is within a repository stored in (and symlinked to) a different filesystem path, we want to follow the symlink instead of treating the module as completely empty. ¹https://pubs.opengroup.org/onlinepubs/9699919799.2013edition/basedefs/V1_chap04.html#tag_04_12 Fixes #50807.

cmd/go: use Join functions instead of adding path separators to strings
Adding a file path separator is incorrect for a file path that may be the root directory on a Unix platform (such as in a container or chroot). Adding a path separator is incorrect for a package path prefix that may be the empty string (as in the "std" module in GOROOT/src). And in both cases, a Join function is arguably clearer and simpler anyway. Fixes #51506 (maybe).

encoding/xml: allow overriding by empty namespace
The namespace defined by xmlns="value" can be overridden in every included tag by the empty namespace xmlns="" without a prefix. Method to calculate indent of XML handles depth of tag and its associated namespace is still active even when no indent is required. An XMLName field in a struct means that namespace must be enforced even if empty. This occurs only on an inner tag as an override of any non-empty namespace of its outer tag. An attribute is added to have the required namespace display.

cmd/compile: inline known-size memclrNoHeapPointers calls
This patch rewrites known-size calls to memclrNoHeapPointers with an OpZero.
This significantly improves performance and lets some clears get DSE'd.
One of the cases where this applies is zeroing a known-size array, example:
var x [256]int8
...
for a := range x {
x[a] = 0
}
Other cases can be found in the runtime itself where memclrNoHeapPointers is sometimes directly invoked with a constant.
It seems that for some sized-clears on some architectures (AMD64, maybe others) the memcrlNoHeapPointers is more performant than OpZero.
See the issue #56997 for more details.
