c9888bdfe2 cmd/internal/obj/arm64: fix frame pointer restore in epilogue
For leaf but nonzero-frame functions.

Currently we're not restoring it properly. We also need to restore
it before popping the stack frame, so that the frame won't get
clobbered by a signal handler in the meantime.

Fixes #63830

Needs a test, but I'm not at all sure how we would actually do that. Leaving for inspiration.

9e90a15ba4 cmd/compile/internal/inline/inlheur: enhance call result scoring
This patch makes a small enhancement to call result scoring, to make
it more independent of param value heuristics. For this pair of
functions:

  func caller() {
     v := callee(10)         <<-- this callsite
     if v > 101 {
        ...
     }
  }
  func callee(x int) {
     if x < 0 {
       G = 1
     }
     return 9
  }

The score for the specified call site above would be adjusted only
once, for the "pass constant to parameter that feeds 'if' statement"
heuristic, which didn't reflect the fact that doing the inline enables
not one but two specific deadcode opportunities (first for the code
inside the inlined routine body, then for the "if" downstream of the
inlined call).

This patch changes the call result scoring machinery to use a separate
set of mask bits, so that we can more accurately handle the case
above.

f56c293319 cmd/compile/internal/inline: tweak "returns inlinable func" heuristic
The code that analyzes function return values checks for cases where a
function F always returns the same inlinable function, e.g.

  func returnsFunc() func(*int, int) { return setit }
  func setit(p *int, v int) { *p = v }

The check for inlinability was being done by looking at "fn.Inl !=
nil", which is probably not what we want, since it includes functions
whose cost value is between 80 and 160 and may only be inlined if lots
of other heuristics kick in.

This patch changes the "always returns same inlinable func" heuristic
to ensure that the func in question has a size of 80 or less, so as to
restrict this case to functions that have a high likelihood of being
inlined.

ff19f8e763 net/http/cgi: eliminate use of Perl in tests
Previously, a Perl script was used to test the net/http/cgi package.
This sometimes led to hidden failures as these tests were not run
on builders without Perl.
Also, this approach posed maintenance difficulties for those
unfamiliar with Perl.

We have now replaced Perl-based tests with a Go handler to simplify
maintenance and ensure consistent testing environments.
It's part of our ongoing effort to reduce reliance on Perl throughout
the Go codebase (see #20032,#25586,#25669,#27779),
thus improving reliability and ease of maintenance.

8b4e1259d0 cmd/compile: fix findIndVar so it does not match disjointed loop headers
Fix #63955

parseIndVar, prove and maybe more are on the assumption that the loop header
is a single block. This can be wrong, ensure we don't match theses cases we
don't know how to handle.

In the future we could update them so that they know how to handle such cases
but theses cases seems rare so I don't think the value would be really high.
We could also run a loop canonicalization pass first which could handle this.

The repro case looks weird because I massaged it so it would crash with the
previous compiler.

cae35cd258 path/filepath: fix various issues in parsing Windows paths
On Windows, A root local device path is a path which begins with
\\?\ or \??\.  A root local device path accesses the DosDevices
object directory, and permits access to any file or device on the
system. For example \??\C:\foo is equivalent to common C:\foo.

The Clean, IsAbs, IsLocal, and VolumeName functions did not
recognize root local device paths beginning with \??\.

Clean could convert a rooted path such as \a\..\??\b into
the root local device path \??\b. It will now convert this
path into .\??\b.

IsAbs now correctly reports paths beginning with \??\
as absolute.

IsLocal now correctly reports paths beginning with \??\
as non-local.

VolumeName now reports the \??\ prefix as a volume name.

Join(`\`, `??`, `b`) could convert a seemingly innocent
sequence of path elements into the root local device path
\??\b. It will now convert this to \.\??\b.

In addition, the IsLocal function did not correctly
detect reserved names in some cases:

  - reserved names followed by spaces, such as "COM1 ".
  - "COM" or "LPT" followed by a superscript 1, 2, or 3.

IsLocal now correctly reports these names as non-local.

8a360d68c4 net/http: set/override Content-Length for encoded range requests
Currently, http.ServeContent returns invalid Content-Length header if:

* Request is a range request.
* Content is encoded (e.g., gzip compressed).
* Content-Length of the encoded content has been set before calling
  http.ServeContent, as suggested in https://github.com/golang/go/issues/19420.

Example:

	w.Header().Set("Content-Type", "application/json")
	w.Header().Set("Content-Length", strconv.Itoa(len(compressedJsonBody)))
	w.Header().Set("Content-Encoding", "gzip")
	w.Header().Set("Etag", etag)
	http.ServeContent(
		w, req, "", time.Time{},
		bytes.NewReader(compressedJsonBody),
	)

The issue is that http.ServeContent currently sees Content-Length as
something optional when Content-Encoding is set, but that is a problem
with range request which can send a payload of different size. So this
reverts https://go.dev/cl/4538111 and makes Content-Length be set
always to the number of bytes which will actually be send (both for
range and non-range requests).

Without this fix, this is an example response:

	HTTP/1.1 206 Partial Content
	Accept-Ranges: bytes
	Content-Encoding: gzip
	Content-Length: 351
	Content-Range: bytes 100-350/351
	Content-Type: application/json; charset=UTF-8
	Etag: "amCTP_vgT5PQt5OsAEI7NFJ6Hx1UfEpR5nIaYEInfOA"
	Date: Sat, 29 Jan 2022 14:42:15 GMT

As you see, Content-Length is invalid and should be 251.

ab79684cdf runtime: donate racectx to g0 in ReadMetricsSlow
ReadMetricsSlow was updated to call the core of readMetrics on the
systemstack to prevent issues with stat skew if the stack gets moved
between readmemstats_m and readMetrics. However, readMetrics calls into
the map implementation, which has race instrumentation. The system stack
typically has no racectx set, resulting in crashes.

Donate racectx to g0 like the tracer does, so that these accesses don't
crash.

6a32ecc059 runtime: eliminate possible stack movements in ReadMetricsSlow
Currently it's possible (and even probable, with mayMoreStackMove mode)
for a stack allocation to occur between readmemstats_m and readMetrics
in ReadMetricsSlow. This can cause tests to fail by producing metrics
that are inconsistent between the two sources.

Fix this by breaking out the critical section of readMetrics and calling
that from ReadMetricsSlow on the systemstack. Our main constraint in
calling readMetrics on the system stack is the fact that we can't
acquire the metrics semaphore from the system stack. But if we break out
the critical section, then we can acquire that semaphore before we go on
the system stack.

While we're here, add another readMetrics call before readmemstats_m.
Since we're being paranoid about ways that metrics could get skewed
between the two calls, let's eliminate all uncertainty. It's possible
for readMetrics to allocate new memory, for example for histograms, and
fail while it's reading metrics. I believe we're just getting lucky
today with the order in which the metrics are produced. Another call to
readMetrics will preallocate this data in the samples slice. One nice
thing about this second read is that now we effectively have a way to
check if readMetrics really will allocate if called a second time on the
same samples slice.

Fixes #60607.

8b14e998fb cmd/go/internal/modfetch: show real URL in response body read errors
CL 233437 added a redactedURL field to proxyRepo, a struct that already
had a field named 'url'. Neither fields were documented, so the similar
names suggest the most natural interpretation that proxyRepo.redactedURL
is equivalent to proxyRepo.url.Redacted() rather than something else.
That's possibly why it was joined with the module version in CL 406675.

It turns out the two URLs differ in more than just redaction: one is the
base proxy URL with (escaped) module path joined, the other is just the
base proxy URL, in redacted form.

Document and rename the fields to make the distinction more clear, and
include all 3 of base module proxy URL + module path + module version
in the reported URL, rather than just the first and third bits as seen
in the errors at https://go.dev/issue/51323#issuecomment-1735812250.

e2d9574b14 crypto/x509: fix certificate policy marshaling
CL 520535 added the new OID type, and the Certificate field Policies to
replace PolicyIdentifiers. During review I missed three problems: (1)
the marshaling of Certificate didn't take into account the case where
both fields were populated with the same OIDs (which would be the case
if you parsed a certificate and used it as a template), (2)
buildCertExtensions only generated the certificate policies extension if
PolicyIdentifiers was populated, and (3) how we would marshal an empty
OID (i.e. OID{}).

This change makes marshaling a certificate with an empty OID an error,
and only adds a single copy of any OID that appears in both Policies and
PolicyIdentifiers to the certificate policies extension. This should
make the round trip behavior for certificates reasonable.

Additionally this change documents that CreateCertificate uses the
Policies field from the template, and fixes buildCertExtensions to
populate the certificate policies extension if _either_
PolicyIdentifiers or Policies is populated, not just PolicyIdentifiers.

Fixes #63909

Since Wasmtime 13 and older don't pay attention to WASMTIME_NEW_CLI,
this change increases compatibility of the script, letting it work
with Wasmtime 9.0.1 as currently tested by the old cmd/coordinator, and
with Wasmtime 14.0.4 as currently tested in the new LUCI infrastructure.

The rest of the transition is left as future work.

b7cbcf0c27 syscall: copy rlimit.go's build constraint to rlimit_test.go
Tests in rlimit_test.go exist to test the behavior of automatically
bumping RLIMIT_NOFILE on Unix implemented in rlimit.go (issue #46279),
with darwin-specific behavior split out into rlimit_darwin.go and
the rest left empty in rlimit_stub.go.

Since the behavior happens only on Unix, it doesn't make sense to test
it on other platforms. Copy rlimit.go's 'unix' build constraint to
rlimit_test.go to accomplish that.

Also simplify the build constraint in rlimit_stub.go while here,
so that its maintenance is easier and it starts to match all
non-darwin Unix GOOS values (previously, 'hurd' happened to be missed).

In particular, this fixes a problem where TestOpenFileLimit was
failing in some environments when testing the wasip1/wasm port.
The RLIMIT_NOFILE bumping behavior isn't implemented there, so
the test was testing the environment and not the Go project.

Updates #46279.

2d428cfd85 cmd/compile: fix unstable selection of hottest edge
When selecting the hottest edge to use for PGO-based devirtualization,
edges are order by:

1. Edge weight
2. If weights are equal, prefer the edge with IR available in the
   package.
3. Otherwise, simply sort lexicographically.

The existing logic for (2) is incomplete.

If the hottest edge so far is missing IR, but the new edge has IR, then
it works as expected and selects the new edge.

But if the hottest edge so far has IR and the new edge is missing IR, we
want to always keep the hottest edge so far, but this logic will fall
through and use lexicographical ordering instead.

Adjust the check to always make an explicit choice when IR availability
differs.
