1cc19e5ba0 cmd/go: allow toolchain upgrades in 'go mod download' when we would already allow go.mod updates
This fixes an inconsistency that was introduced in CL 537480 and noted
in the review on CL 539697.

In particular, 'go mod download' already updates the go.mod file when
other kinds of updates are needed. (#45551 suggested that it should
not do so, but that part of the change was not implemented yet;
finishing that change is proposed as #64008.)

Updates #62054.

07c388f17c syscall: use fchmodat2 in Fchmodat
The fchmodat2 syscall was added in Linux kernel 6.6.  Mirror the
implementation in golang.org/x/sys/unix.Fchmodat (CL 539635) and use
fchmodat2 in Fchmodat if flags are given. It will return ENOSYS on older
kernels (or EINVAL or any other bogus error in some container
implementations).

Also update ztypes_linux_$GOARCH.go for all linux platforms to add
_AT_EMPTY_PATH. It was added to linux/types in CL 407694 but was only
updated for linux/loong64 at that time.

Updates #61636

eebeca803d runtime: clarify error when returning unpinned pointers
With the introduction of runtime.Pinner, returning a pointer to a pinned
struct that then points to an unpinned Go pointer is correctly caught.

However, the error message remained as "cgo result has Go pointer",
which should be updated to acknowledge that Go pointers to pinned
memory are allowed.

This also updates the comments for cgoCheckArg and cgoCheckResult
to similarly clarify.

04d64a3b36 cmd/compile/inline/inleur: use "largest possible score" to revise inlinability
The current GOEXPERIMENT=newinliner strategy us to run "CanInline" for
a given function F with an expanded/relaxed budget of 160 (instead of
the default 80), and then only inline a call to F if the adjustments
we made to F's original score are below 80.

This way of doing things winds up writing out many more functions to
export data that have size between 80 and 160, on the theory that they
might be inlinable somewhere given the right context, which is
expensive from a compile time perspective.

This patch changes things to add a pass that revises the inlinability
of a function after its properties are computed by looking at its
properties and estimating the largest possible negative score
adjustment that could happen given the various return and param props.
If the computed score for the function minus the max adjust is not
less than 80, then we demote it from inlinable to non-inlinable to
save compile time.

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.
