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.

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.

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.

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

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.

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

The RLIMIT_NOFILE bumping behavior isn't implemented there, so
the test was testing the environment and not the Go project.

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

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.

This also allows us to remove the chanWriter helper from the test,
using a simpler strings.Builder instead, relying on
clientServerTest.close for synchronization.
(I don't think this runs afoul of #38370, because the handler
functions themselves in these tests should never be executed,
let alone result in an asynchronous write to the error log.)
Fixes#57599.

Currently verifyGCBitsSlice creates a new array type to represent the
slice backing store, but passes the element type as the slice type in
this construction. This is incorrect, but the tests currently don't care
about it. They will in a follow-up CL, so fix it now.

Go 1.21 and earlier do not understand this line, causing
"go mod vendor" of //go:build go1.22-tagged code that
uses this feature to fail.
The solution is to include the go/build change to skip over
the line in Go 1.22 (making "go mod vendor" from Go 1.22 onward
work with this change) and then wait to deploy the cgo change
until Go 1.23, at which point Go 1.21 and earlier will be unsupported.
For #56378.
Fixes#63293.

Since CL 226138, TestNohup has a bit of a strange construction: it wants
to run the "uncaught" subtests in parallel with each other, and the
"nohup" subtests in parallel with each other, but also needs join
between "uncaught" and "nohop" so it can Stop notifying for SIGHUP.
It achieves this by doing `go t.Run` with a WaitGroup rather than using
`t.Parallel` in the subtest (which would make `t.Run` return immediately).
However, this makes things more difficult to understand than necessary.
As noted on https://pkg.go.dev/testing#hdr-Subtests_and_Sub_benchmarks,
a second layer of subtest can be used to join parallel subtests.
Switch to this form, which makes the test simpler to follow
(particularly the cleanup that goes with "uncaught").
For #63799.

This is a port of CL 538856 from the syntax parser to go/parser.
As part of the port, make more portions of parseParameterList
matching the equivalent paramList method (from the syntax parser).
As a result, this now also produces a better error message in cases
where the missing piece might not be a type parameter name but a
constraint (this fixes a TODO in a test).
Improve comments in the code and adjust the corresponding comments
in the syntax parser.
Change references to issues to use the format go.dev/issue/ddddd.
For #60812.
