The current implementation of the http package strips double quotes
from the cookie-value during parsing, resulting in the serialized
cookie not including them. This patch addresses this limitation by
introducing a new field to track whether the original value was
enclosed in quotes.
Additionally, the internal representation of a cookie in the cookiejar
package has been adjusted to align with the new representation.
The syntax of cookies is outlined in RFC 6265 Section 4.1.1:

This is the final CL in the series adding PGO preprocessing support to
cmd/go. Now that the tool is hooked up, we integrate with the build
cache to cache the result.
This is fairly straightforward. One difference is that the compile and
link do caching through updateBuildID. However, preprocessed PGO files
don't have a build ID, so it doesn't make much sense to hack our way
through that function when it is simple to just add to the cache
ourselves.
As as aside, we could add a build ID to the preproccessed file format,
though it is not clear if it is worthwhile. The one place a build ID
could be used is in buildActionID, which currently compute the file hash
of the preprocessed profile. With a build ID it could simply read the
build ID. This would save one complete read of the file per build
(cmd/go caches the hash), but each compile process also reads the entire
file, so this is a small change overall.
Fixes#58102.

A proposal discussion in mid-2020 on #37196 decided to change
time.Timer and time.Ticker so that their Stop and Reset methods
guarantee that no old value (corresponding to the previous configuration
of the Timer or Ticker) will be received after the method returns.
The trivial way to do this is to make the Timer/Ticker channels
unbuffered, create a goroutine per Timer/Ticker feeding the channel,
and then coordinate with that goroutine during Stop/Reset.
Since Stop/Reset coordinate with the goroutine and the channel
is unbuffered, there is no possibility of a stale value being sent
after Stop/Reset returns.
Of course, we do not want an extra goroutine per Timer/Ticker,
but that's still a good semantic model: behave like the channels
are unbuffered and fed by a coordinating goroutine.
The actual implementation is more effort but behaves like the model.
Specifically, the timer channel has a 1-element buffer like it always has,
but len(t.C) and cap(t.C) are special-cased to return 0 anyway, so user
code cannot see what's in the buffer except with a receive.
Stop/Reset lock out any stale sends and then clear any pending send
from the buffer.
Some programs will change behavior. For example:
package main
import "time"
func main() {
t := time.NewTimer(2 * time.Second)
time.Sleep(3 * time.Second)
if t.Reset(2*time.Second) != false {
panic("expected timer to have fired")
}
<-t.C
<-t.C
}
This program (from #11513) sleeps 3s after setting a 2s timer,
resets the timer, and expects Reset to return false: the Reset is too
late and the send has already occurred. It then expects to receive
two values: the one from before the Reset, and the one from after
the Reset.
With an unbuffered timer channel, it should be clear that no value
can be sent during the time.Sleep, so the time.Reset returns true,
indicating that the Reset stopped the timer from going off.
Then there is only one value to receive from t.C: the one from after the Reset.
In 2015, I used the above example as an argument against this change.
Note that a correct version of the program would be:
func main() {
t := time.NewTimer(2 * time.Second)
time.Sleep(3 * time.Second)
if !t.Reset(2*time.Second) {
<-t.C
}
<-t.C
}
This works with either semantics, by heeding t.Reset's result.
The change should not affect correct programs.
However, one way that the change would be visible is when programs
use len(t.C) (instead of a non-blocking receive) to poll whether the timer
has triggered already. We might legitimately worry about breaking such
programs.
In 2020, discussing #37196, Bryan Mills and I surveyed programs using
len on timer channels. These are exceedingly rare to start with; nearly all
the uses are buggy; and all the buggy programs would be fixed by the new
semantics. The details are at [1].
To further reduce the impact of this change, this CL adds a temporary
GODEBUG setting, which we didn't know about yet in 2015 and 2020.
Specifically, asynctimerchan=1 disables the change and is the default
for main programs in modules that use a Go version before 1.23.
We hope to be able to retire this setting after the minimum 2-year window.
Setting asynctimerchan=1 also disables the garbage collection change
from CL 568341, although users shouldn't need to know that since
it is not a semantically visible change (unless we have bugs!).
As an undocumented bonus that we do not officially support,
asynctimerchan=2 disables the channel buffer change but keeps
the garbage collection change. This may help while we are
shaking out bugs in either of them.
Fixes#37196.

From the beginning of Go, the time package has had a gotcha:
if you use a select on <-time.After(1*time.Minute), even if the select
finishes immediately because some other case is ready, the underlying
timer from time.After keeps running until the minute is over. This
pins the timer in the timer heap, which keeps it from being garbage
collected and in extreme cases also slows down timer operations.
The lack of garbage collection is the more important problem.
The docs for After warn against this scenario and suggest using
NewTimer with a call to Stop after the select instead, purely to work
around this garbage collection problem.
Oddly, the docs for NewTimer and NewTicker do not mention this
problem, but they have the same issue: they cannot be collected until
either they are Stopped or, in the case of Timer, the timer expires.
(Tickers repeat, so they never expire.) People have built up a shared
knowledge that timers and tickers need to defer t.Stop even though the
docs do not mention this (it is somewhat implied by the After docs).
This CL fixes the garbage collection problem, so that a timer that is
unreferenced can be GC'ed immediately, even if it is still running.
The approach is to only insert the timer into the heap when some
channel operation is blocked on it; the last channel operation to stop
using the timer takes it back out of the heap. When a timer's channel
is no longer referenced, there are no channel operations blocked on
it, so it's not in the heap, so it can be GC'ed immediately.
This CL adds an undocumented GODEBUG asynctimerchan=1
that will disable the change. The documentation happens in
the CL 568341.

Add the Localize function, which takes an io/fs slash-separated path
and returns an operating system path.
Localize returns an error if the path cannot be represented on
the current platform.
Replace internal/safefile.FromFS with Localize,
which serves the same purpose as this function.
The internal/safefile package remains separate from path/filepath
to avoid a dependency cycle with the os package.

Due to a bug in golang.org/x/build/relnote, API features affecting

This CL vendors in the fixed golang.org/x/build. (That caused other

It also renames the syscall relnote file to remove the build tags

This also explains the valid arguments for unsafe.Slice which are

unsafe.SliceData simply refers to "slice argument" and we use
similar terminology elsewhere in the spec to denote values that
have a core type of slice (or any other type for that matter).

Go 1.21.1 and Go 1.22 have ceased working around an issue with Linux
kernel defaults for transparent huge pages that can result in excessive
memory overheads. (https://bugzilla.kernel.org/show_bug.cgi?id=93111)
Many Linux distributions disable huge pages altogether these days, so
this problem isn't quite as far-reaching as it used to be. Also, the
problem only affects Go programs with very particular memory usage
patterns.
That being said, because the runtime used to actively deal with this
problem (but with some unpredictable behavior), it's preventing users
that don't have a lot of control over their execution environment from
upgrading to Go beyond Go 1.20.
This change adds a GODEBUG to smooth over the transition. The GODEBUG
setting disables transparent huge pages for all heap memory on Linux,
which is much more predictable than restoring the old behavior.
Fixes#64332.

Previously, its value was unset (NoPos), but the correct
value is a point after the signature (FuncType.End) and
before the body.
Also, fix a bug in Scope.Innermost whereby it would return
the wrong (outer) scope when the query position was in
the FuncType portion of a Func{Decl,Lit}.
The fix is to set the scope's pos/end to those of the
complete Func{Decl,Lit}. This is now documented at
Info.Scopes, along with other missing information.
Also, fix a bug in the go/types (but not types2) scope
test, in which comments were discarded by the parser,
causing the entire test to be a no-op (!).
Also, make failures of TestScopeLookupParent more
informative.
Also, add a release note about the change in behavior.

This CL exports the previously unexported Alias type and
corresponding functions and methods per issue #63223.
Whether Alias types are used or not is controlled by
the gotypesalias setting with the GODEBUG environment
variable. Setting gotypesalias to "1" enables the Alias
types:
GODEBUG=gotypesalias=1
By default, gotypesalias is not set.
Adjust test cases that enable/disable the use of Alias
types to use -gotypesalias=1 or -gotypesalias=0 rather
than -alias and -alias=false for consistency and to
avoid confusion.

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.

This CL clarifies the order of evaluation of the binary logical
operators, && and ||. The clarified semantics matches what cmd/compile
and x/tools/go/ssa already implement, and prohibit some optimizations
that are arguably allowed today but risk surprising users.
First, it specifies that the left operand is evaluated before the
right operand. This prohibits "(f() || true) && *p" from evaluating
"*p" before "f()".
Second, it specifies that binary logical operations are also ordered
lexically left-to-right with regard to function calls and receive
operations. This prohibits "h(*p || true || f(), g())" from evaluating
"*p" after "g()".
Finally, the "order of evaluation of [...] is not specified" wording
in the example is clarified to acknowledge that there are still some
other orderings that are implied lexically; e.g., x must be evaluated
and indexed before g(), and z now must be evaluated before h(). (Note:
Whether z is evaluated before or after f() remains unspecified, as
there's no lexical dependency.)

The upcoming built-in zero value provides an idiomatic way
to test for zero by comparing to the zero literal: v == zero.
The reflect package is meant to provide a programmatic way to perform
operations that the Go language itself provides.
Thus, it seems prudent that reflect.ValueOf(&v).Elem().IsZero() is
identical to v == zero.
This change alters the behavior of Value.IsZero in two concrete ways:
* negative zero is identical to zero
* blank fields in a struct are ignored
Prior to this change, we were already in an inconsistent state
due to a regression introduced by CL 411478.
The new behavior was already the case for comparable composite types.
This change makes it consistent for all other types
(in particular incomparable composite types and standalone numbers).

When adding MPTCP support to address the proposal #56539, I missed the
GODEBUG setting from Russ Cox's plan:
I am inclined to say that we add MPTCP as an opt-in for a release or
two, and then make it opt-out. There should be a GODEBUG setting (...)
See: https://github.com/golang/go/issues/56539#issuecomment-1309294637
Thanks to andrius4669 for having reported this issue to me.
It makes sense to have this GODEBUG setting not to have to modify
applications to use MPTCP (if available). It can then be useful to
estimate the impact in case we want to switch from opt-in to opt-out
later.
The MPTCP E2E test has been modified to make sure we can enable MPTCP
either via the source code like it was already the case before or with
this environment variable:
GODEBUG=multipathtcp=1
The documentation has been adapted accordingly.
I don't know if it is too late for Go 1.21 but I had to put a version in
the documentation. The modification is small, the risk seems low and
this was supposed to be there from the beginning according to Russ Cox's
specifications. It can also be backported or only be present in the
future v1.22 if it is easier.
Note: I didn't re-open #56539 or open a new one. It is not clear to me
what I should do in this case.

Put the sections for the various built-ins into alphabetical order
based on the built-in name, while keeping built-ins that belong
together together.
The order is now (captialized letter determines order):
- Append
- Clear
- Close
- Complex, real, imag
- Delete
- Len, cap
- Make
- Min, max (to be inserted here)
- New
- Panic, recover
- Print, println
There are some white space adjustments but no changes to the prose
of the moved sections.

This adds the three functions from #56102 to the sync package. These
provide a convenient API for the most common uses of sync.Once.
The performance of these is comparable to direct use of sync.Once:
$ go test -run ^$ -bench OnceFunc\|OnceVal -count 20 | benchstat -row .name -col /v
goos: linux
goarch: amd64
pkg: sync
cpu: 11th Gen Intel(R) Core(TM) i7-1185G7 @ 3.00GHz
│ Once │ Global │ Local │
│ sec/op │ sec/op vs base │ sec/op vs base │
OnceFunc 1.3500n ± 6% 2.7030n ± 1% +100.22% (p=0.000 n=20) 0.3935n ± 0% -70.86% (p=0.000 n=20)
OnceValue 1.3155n ± 0% 2.7460n ± 1% +108.74% (p=0.000 n=20) 0.5478n ± 1% -58.35% (p=0.000 n=20)
The "Once" column represents the baseline of how code would typically
express these patterns using sync.Once. "Global" binds the closure
returned by OnceFunc/OnceValue to global, which is how I expect these
to be used most of the time. Currently, this defeats some inlining
opportunities, which roughly doubles the cost over sync.Once; however,
it's still *extremely* fast. Finally, "Local" binds the returned
closure to a local variable. This unlocks several levels of inlining
and represents pretty much the best possible case for these APIs, but
is also unlikely to happen in practice. In principle the compiler
could recognize that the global in the "Global" case is initialized in
place and never mutated and do the same optimizations it does in the
"Local" case, but it currently does not.

Long ago we decided that panic(nil) was too unlikely to bother
making a special case for purposes of recover. Unfortunately,
it has turned out not to be a special case. There are many examples
of code in the Go ecosystem where an author has written panic(nil)
because they want to panic and don't care about the panic value.
Using panic(nil) in this case has the unfortunate behavior of
making recover behave as though the goroutine isn't panicking.
As a result, code like:
func f() {
defer func() {
if err := recover(); err != nil {
log.Fatalf("panicked! %v", err)
}
}()
call1()
call2()
}
looks like it guarantees that call2 has been run any time f returns,
but that turns out not to be strictly true. If call1 does panic(nil),
then f returns "successfully", having recovered the panic, but
without calling call2.
Instead you have to write something like:
func f() {
done := false
defer func() {
if err := recover(); !done {
log.Fatalf("panicked! %v", err)
}
}()
call1()
call2()
done = true
}
which defeats nearly the whole point of recover. No one does this,
with the result that almost all uses of recover are subtly broken.
One specific broken use along these lines is in net/http, which
recovers from panics in handlers and sends back an HTTP error.
Users discovered in the early days of Go that panic(nil) was a
convenient way to jump out of a handler up to the serving loop
without sending back an HTTP error. This was a bug, not a feature.
Go 1.8 added panic(http.ErrAbortHandler) as a better way to access the feature.
Any lingering code that uses panic(nil) to abort an HTTP handler
without a failure message should be changed to use http.ErrAbortHandler.
Programs that need the old, unintended behavior from net/http
or other packages can set GODEBUG=panicnil=1 to stop the run-time error.
Uses of recover that want to detect panic(nil) in new programs
can check for recover returning a value of type *runtime.PanicNilError.
Because the new GODEBUG is used inside the runtime, we can't
import internal/godebug, so there is some new machinery to
cross-connect those in this CL, to allow a mutable GODEBUG setting.
That won't be necessary if we add any other mutable GODEBUG settings
in the future. The CL also corrects the handling of defaulted GODEBUG
values in the runtime, for #56986.
Fixes#25448.

CL 444277 fixed Time.UnmarshalText and Time.UnmarshalJSON to properly
unmarshal timestamps according to RFC 3339 instead of according
to Go's bespoke time syntax that is a superset of RFC 3339.
However, this change seems to have broken an AWS S3 unit test
that relies on parsing timestamps with single digit hours.
It is unclear whether S3 emits these timestamps in production or
whether this is simply a testing artifact that has been cargo culted
across many code bases. Either way, disable strict parsing for now
and re-enable later with better GODEBUG support.

The arena goexperiment contains code used inside Google in very
limited use cases that we will maintain, but the discussion on #51317
identified serious problems with the very idea of adding arenas to the
standard library. In particular the concept tends to infect many other
APIs in the name of efficiency, a bit like sync.Pool except more
publicly visible.
It is unclear when, if ever, we will pick up the idea and try to push
it forward into a public API, but it's not going to happen any time
soon, and we don't want users to start depending on it: it's a true
experiment and may be changed or deleted without warning.
The arena text in the release notes makes them seem more official
and supported than they really are, and we've already seen a couple
blog posts based on that erroneous belief. Delete the text to try to
set expectations better.
