cuishuang 3a81ebea0d net/http: use strings.FieldsFuncSeq to reduce memory allocations
After using strings.FieldsFuncSeq, the number of memory allocations has been reduced from 2 to 0.

The following is the complete benchamark code and results:

package main

import (
	"strings"
	"testing"
)

func isSlashRune(r rune) bool { return r == '/' || r == '\\' }

func containsDotDotLoop(v string) bool {
	if !strings.Contains(v, "..") {
		return false
	}
	for _, ent := range strings.FieldsFunc(v, isSlashRune) {
		if ent == ".." {
			return true
		}
	}
	return false
}

func containsDotDotSeq(v string) bool {
	if !strings.Contains(v, "..") {
		return false
	}
	for ent := range strings.FieldsFuncSeq(v, isSlashRune) {
		if ent == ".." {
			return true
		}
	}
	return false
}

func BenchmarkDotDot(b *testing.B) {
	testCases := []string{
		"/path/to/somewhere",
		"/path/../to/somewhere",
		"/really/long/path/with/many/segments",
		"../../../deep/path",
	}

	b.Run("Loop", func(b *testing.B) {
		for i := 0; i < b.N; i++ {
			for _, tc := range testCases {
				containsDotDotLoop(tc)
			}
		}
	})

	b.Run("Seq", func(b *testing.B) {
		for i := 0; i < b.N; i++ {
			for _, tc := range testCases {
				containsDotDotSeq(tc)
			}
		}
	})
}

Jakub Ciolek 691b7ff1c7 internal/fuzz: use a lookup table for SnapshotCoverage
Previously, the implementation used bit manipulation to approximate
counters to the nearest power of two.

Given the 0-255 range of byte, we can precompute values at
initialization and use a lookup table, reducing runtime computation.

Benchmarks show an 18% performance gain on AMD64 and 5% on ARM64.

* net/netip/FuzzParse (n=10, t=60s, state reset per run)
  * AMD64 (Intel Alder Lake i5-12600k):

    17,349,217 -> 20,487,756 execs/s

  * ARM64 (M3 Pro):

    19,606,471 -> 20,657,041 execs/s

* compress/gzip/FuzzReader (n=10, t=60s, mature corpus)
  * AMD64 (Intel Alder Lake i5-12600k):

    5,655,956 -> 6,707,035 execs/s

Roxy Light f7b8dd9033 io/fs: add ReadLinkFS interface
Added implementations for *io/fs.subFS, os.DirFS, and testing/fstest.MapFS.
Amended testing/fstest.TestFS to check behavior.

Addressed TODOs in archive/tar and os.CopyFS around symbolic links.

I am deliberately not changing archive/zip in this CL,
since it currently does not resolve symlinks
as part of its filesystem implementation.
I am unsure of the compatibility restrictions on doing so,
so figured it would be better to address independently.

testing/fstest.MapFS now includes resolution of symlinks,
with MapFile.Data storing the symlink data.
The behavior change there seemed less intrusive,
especially given its intended usage in tests,
and it is especially helpful in testing the io/fs function implementations.

Fixes #49580

Michael Anthony Knyszek b25b5f3ff4 runtime: fix GODEBUG=gccheckmark=1 and add smoke test
This change fixes GODEBUG=gccheckmark=1 which seems to have bit-rotted.
Because the root jobs weren't being reset, it wasn't doing anything.
Then, it turned out that checkmark mode would queue up noscan objects in
workbufs, which caused it to fail. Then it turned out checkmark mode was
broken with user arenas, since their heap arenas are not registered
anywhere. Then, it turned out that checkmark mode could just not run
properly if the goroutine's preemption flag was set (since
sched.gcwaiting is true during the STW). And lastly, it turned out that
async preemption could cause erroneous checkmark failures.

This change fixes all these issues and adds a simple smoke test to dist
to run the runtime tests under gccheckmark, which exercises all of these
issues.

Fixes #69074.
Fixes #69377.
Fixes #69376.

This reverts CL 603295.

Reason for revert: can cause child exit_group to hang.

This is not a clean revert. CL 603098 did a major refactoring of the
tests. That refactor is kept, just the sendfile-specific tests are
dropped from the linux tests.

Fixes #71375.

Michael Pratt 8071f2a169 runtime: mapiter linkname compatibility layer
This CL reintroduces the various mapiter* linkname functions with a
compatibility layer that is careful to maintain compatibility with users
of the linkname.

The wrappers are straightforward. Callers of these APIs get an extra
layer of indirection, with their hiter containing a pointer to the real
maps.Iter. These users will take a minor performance hit from the extra
allocation, but this approach should have good long-term
maintainability.

Fixes #71408.

Michael Pratt 78e6f2a1c8 runtime: rename mapiterinit and mapiternext
mapiterinit allows external linkname. These users must allocate their
own iter struct for initialization by mapiterinit. Since the type is
unexported, they also must define the struct themselves. As a result,
they of course define the struct matching the old hiter definition (in
map_noswiss.go).

The old definition is smaller on 32-bit platforms. On those platforms,
mapiternext will clobber memory outside of the caller's allocation.

On all platforms, the pointer layout between the old hiter and new
maps.Iter does not match. Thus the GC may miss pointers and free
reachable objects early, or it may see non-pointers that look like heap
pointers and throw due to invalid references to free objects.

To avoid these issues, we must keep mapiterinit and mapiternext with the
old hiter definition. The most straightforward way to do this is to use
mapiterinit and mapiternext as a compatibility layer between the old and
new iter types.

The first step to that is to move normal map use off of these functions,
which is what this CL does.

Introduce new mapIterStart and mapIterNext functions that replace the
former functions everywhere in the toolchain. These have the same
behavior as the old functions.

This CL temporarily makes the old functions throw to ensure we don't
have hidden dependencies on them. We cannot remove them entirely because
GOEXPERIMENT=noswissmap still uses the old names, and internal/goobj
requires all builtins to exist regardless of GOEXPERIMENT. The next CL
will introduce the compatibility layer.

I want to avoid using linkname between runtime and reflect, as that
would also allow external linknames. So mapIterStart and mapIterNext are
duplicated in reflect, which can be done trivially, as it imports
internal/runtime/maps.

For #71408.
