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.

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.

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.

It's part of our ongoing effort to reduce reliance on Perl throughout

In the future we could update them so that they know how to handle such cases

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

Clean could convert a rooted path such as \a\..\??\b into

IsAbs now correctly reports paths beginning with \??\

IsLocal now correctly reports paths beginning with \??\

VolumeName now reports the \??\ prefix as a volume name.
Join(`\`, `??`, `b`) could convert a seemingly innocent

In addition, the IsLocal function did not correctly

- "COM" or "LPT" followed by a superscript 1, 2, or 3.

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.

The comment on runCleanup states "If catchPanic is true ...", but
there is no catchPanic argument or variable. This was introduced
in CL 214822, which introduced the panicHandling type. The code was
updated during code review, but the comment was missed.

Previously, badmorestackg0 was never called since it was behind a g ==
R1 check, R1 holding g.m. This is clearly wrong, since we want to check
if g == g0. Fixed by using R2 that holds the value of g0.

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.
For #60607.

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.

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.

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.

The latest version of Wasmtime, 14.0.4 as of writing this, offers a new
CLI while also supporting the old CLI. Since this is known and tracked
in issue #63718, silence the warning that otherwise causes many tests
to fail.
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.
