This is a followup to CL 110296. That change added a new behavior to Redirect, where the short HTML body is not written if the Content-Type header is already set. It was implemented by doing an early return. That unintentionally prevented the correct status code from being written, so it would always default to 200. Existing tests didn't catch this because they don't check status code. This change fixes that issue by removing the early return and moving the code to write a short HTML body behind an if statement. It adds written status code checks to Redirect tests. It also tries to improve the documentation wording and code style in TestRedirect_contentTypeAndBody. Updates #25166.

CL 108095 goes to some length inorder to keep the stack usage of getHPETTimecounter code paths bellow a limit being checked by the linker analysis. That limit is spurious, when running on the system or signal stack. In a similar scenario, cgocallback_gofunc performs an indirect call through AX to hide the call from the linker analysis. Here instead, mark getHPETTimecounter //go:systemstack and call it appropriately.

When dist test was updated to run "go test" with multiple package arguments at once, merging the logical test units into one execution, the hack to give cmd/go twice as much time wasn't updated. What was happening (even in the all.bash case) was that we were merging together, say, "cmd/go" and "bytes", and because bar was lexically earlier, the timeout calculation was based on package "byte", even though we were actually running, say: "go test bytes cmd/go". This explains why x/build/cmd/release was often flaky with its all.bash, since cmd/go can't really finish in 3 minutes reliably unless it's running by itself. If it has any competition, it runs over.

The macOS and iOS external linker strips DWARF information from binaries because it assumes the information will go into separate DWARF information .dSYM files. To preserve the embedded debugging information, the Go linker re-combines the separate DWARF information into the unmapped __DWARF segment of the final executable. However, the iOS dyld linker does not allow unmapped segments, so use the presence of the LC_VERSION_MIN_IPHONEOS linker command to skip DWARF combining. Note that we can't use GOARCH for detection since the iOS emulator runs on GOARCH=386 and GOARCH=amd64 and we will run into https://golang.org/issues/25148. Updates #25148.

linux/ppc64 uses the ppc64 v1 ABI which was never fully supported by Go. (linux/ppc64le uses the ppc64 v2 ABI and that is fully supported). As a result if the external linker is used to build a program on ppc64, there is a either a warning or error message that doesn't clearly describe the problem. In the case of a warning, a program is created that will most likely not execute since it is not built as expected for the ppc64 dynamic linker (ld64.so.1). To avoid confusion in these cases, error messages are now issued if external linker is explicitly used to build the program. Note that most buildmodes that require external linking were already flagging linux/ppc64 as unsupported except for c-archive, which has been added here. This problem does not occur with gccgo since the ppc64 v1 ABI is supported there.

fmt's %d, %x, and %X all accept pointer arguments. However, in cmd/vet's printVerbs table, they were defined as if they did not accept pointer arguments. This inconsistency with fmt did not manifest to users since the vet codebase worked around it. In particular, pointer arguments were usually allowed for verbs that accepted integers, as the *types.Pointer argument type case read the following: t&(argInt|argPointer) != 0 As a result, using the %q verb with a pointer resulted in a bug in cmd/vet: $ go run f.go %!q(*int=0xc000014140) $ go vet f.go [no warning] As documented, fmt's %q verb only accepts runes (integers), strings, and byte slices. It should not accept pointers, and it does not. But since vet mixed integers and pointers, it wasn't properly warning about the misuse of fmt. This patch surfaced another bug with fmt.Printf("%p", nil): $ go run f.go %!p(<nil>) $ go vet f.go [no warning] As documented, fmt's %p verb only accepts pointers, and untyped nil is not a valid pointer. But vet did not warn about it, which is another inconsistency with fmt's documented rules. Fix that too, with a test, also getting rid of the TODO associated with the code. As a result of those changes, fix a wrong use of the fmt format verbs in the standard library, now correctly spotted by vet. Fixes #25233.

This is a follow-up of CL 93637. There, when we redirect sync/atomic to runtime/internal/atomic, a few good implementations of ARM atomics were lost. This CL brings most of them back, with some improvements. - Change atomic Store to a plain store with memory barrier, as we already changed atomic Load to plain load with memory barrier. - Use native 64-bit atomics on ARMv7, jump to Go implementations on older machines. But drop the kernel helper. In particular, for Load64, just do loads, not using Cas on the address being load from, so it works also for read-only memory (since we have already fixed 32-bit Load).

The implementation of atomics are inherently tricky. It would be good to have them implemented in a single place, instead of multiple copies. Mostly a simple redirect. On 386, some functions in sync/atomic have better implementations, which are moved to runtime/internal/atomic. On ARM, some functions in sync/atomic have better implementations. They are dropped by this CL, but restored with an improved version in a follow-up CL. On linux/arm, 64-bit CAS kernel helper is dropped, as we're trying to move away from kernel helpers.

Remove unnecessary check and corresponding misleading comment. Found while investigating solutions for @23203.
