2023-02-06all: upgrade Unicode from 13.0.0 to 15.0.0weebney
Update unicode/tables.go to reflect changes in the Unicode Standard up to Unicode 15.0.0, released 13 Sept 2022. In order to accommodate this update, strconv/isPrint has been updated to reflect changes in printable characters. Also changed is template/exec_test.go for both text and html packages- in the test "TestJSEscaping", rune U+FDFF was used as a placeholder for an unprintable character. This codepoint was assigned and made printable in Unicode 14.0.0, breaking this test. It has been replaced with the assigned and never-printable U+FFFE to fix the test and provide resiliency in the future. This upgrade bypasses Unicode 14.0.0, but is compatible.

2023-01-19runtime: replace panic(nil) with panic(new(runtime.PanicNilError))Russ Cox
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.

2022-12-01go/types, types2: make the new comparable semantics the defaultRobert Griesemer
Ordinary interface types now satisfy comparable constraints. This is a fully backward-compatible change: it simply permits additional code to be valid that wasn't valid before. This change makes the new comparable semantics the default behavior, depending on the Go -lang version. It also renames the flag types2.Config.AltComparableSemantics to types2.Config.OldComparableSemantics and inverts its meaning (or types.Config.oldComparableSemantics respectively). Add new predicate Satisfies (matching the predicate Implements but for constraint satisfaction), per the proposal description. Adjust some existing tests by setting -oldComparableSemantics and add some new tests that verify version-dependent behavior. The compiler flag -oldcomparable may be used to temporarily switch back to the Go 1.18/1.19 behavior should this change cause problems, or to identify that a problem is unrelated to this change. The flag will be removed for Go 1.21. For #52509. For #56548. For #57011.

crypto/rsa assumes RSA OAEP uses the same hash to be used for both the label and the mask generation function. However, implementations in other languages, such as Java and Python, allow these parameters to be specified independently. This change allows the MGF hash to be specified independently for decrypt operations in order to allow decrypting ciphertexts generated in other environments.

2022-11-08context: add APIs for writing and reading cancelation causeSameer Ajmani
Extend the context package to allow users to specify why a context was canceled in the form of an error, the "cause". Users write the cause by calling WithCancelCause to construct a derived context, then calling cancel(cause) to cancel the context with the provided cause. Users retrieve the cause by calling context.Cause(ctx), which returns the cause of the first cancelation for ctx or any of its parents. The cause is implemented as a field of cancelCtx, since only cancelCtx can be canceled. Calling cancel copies the cause to all derived (child) cancelCtxs. Calling Cause(ctx) finds the nearest parent cancelCtx by looking up the context value keyed by cancelCtxKey. API changes: +pkg context, func Cause(Context) error +pkg context, func WithCancelCause(Context) (Context, CancelCauseFunc) +pkg context, type CancelCauseFunc func(error) Fixes #26356 Fixes #51365 Change-Id: I15b62bd454c014db3f4f1498b35204451509e641 Reviewed-on: https://go-review.googlesource.com/c/go/+/375977 Reviewed-by: Damien Neil <dneil@google.com> TryBot-Result: Gopher Robot <gobot@golang.org> Run-TryBot: Sameer Ajmani <sameer@golang.org> Auto-Submit: Sameer Ajmani <sameer@golang.org>

An error which implements an "Unwrap() []error" method wraps all the non-nil errors in the returned []error.

As returns the first matching result, if any. The new errors.Join function returns an error wrapping a list of errors. The fmt.Errorf function now supports multiple instances of the %w verb.

2022-09-09syscall: add CgroupFD support for ForkExec on LinuxKir Kolyshkin
Implement CLONE_INTO_CGROUP feature, allowing to put a child in a specified cgroup in a clean and simple way. Note that the feature only works for cgroup v2, and requires Linux kernel 5.7 or newer. Using the feature requires a new syscall, clone3. Currently this is the only reason to use clone3, but the code is structured in a way so that other cases may be easily added in the future. Add a test case. While at it, try to simplify the syscall calling code in forkAndExecInChild1, which became complicated over time because: 1. It was using either rawVforkSyscall or RawSyscall6 depending on whether CLONE_NEWUSER was set. 2. On Linux/s390, the first two arguments to clone(2) system call are swapped (which deserved a mention in Linux ABI hall of shame). It was worked around in rawVforkSyscall on s390, but had to be implemented via a switch/case when using RawSyscall6, making the code less clear. Let's - modify rawVforkSyscall to have two arguments (which is also required for clone3); - remove the arguments workaround from s390 asm, instead implementing arguments swap in the caller (which still looks ugly but at least it's done once and is clearly documented now); - use rawVforkSyscall for all cases (since it is essentially similar to RawSyscall6, except for having less parameters, not returning r2, and saving/restoring the return address before/after syscall on 386 and amd64).
