* sync: implement OnceFunc, OnceValue, and OnceValuesAustin Clements2023-03-311-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* runtime: replace panic(nil) with panic(new(runtime.PanicNilError))Russ Cox2023-01-191-13/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* time: revert strict parsing of RFC 3339Joe Tsai2023-01-181-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.
