2024-05-15cmd/go: add support for godebug lines in go.mod and go.workRuss Cox
The fact that the go line sets both the language version and the GODEBUG compatibility version can be a problem, especially since the go line is also required to be ≥ the go lines of any required dependency modules. This change adds a new 'godebug' line to go.mod and go.work to allow setting the GODEBUG values for the entire module. It also adds a new meta-value default=go1.21 that means take the defaults from Go 1.21 no matter what the go line says. These were discussed in proposal #65573. Fixes #65573.

2024-01-24cmd/go: add GORISCV64 environment variableMark Ryan
The variable represents the RISC-V user-mode application profile for which to compile. Valid values are rva20u64 (the default) and rva22u64. Setting GORISCV64=rva20u64 defines the riscv64.rva20u64 build tag, sets the internal variable buildcfg.GORISCV64 to 20 and defines the macro GORISCV64_rva20u64 for use in assembly language code. Setting GORISCV64=rva22u64 defines the riscv64.rva20u64 and riscv64.rva22u64 build tags, sets the internal variable buildcfg.GORISCV64 to 22 and defines the macro GORISCV64_rva22u64 for use in assembly language code. This patch only provides a mechanism for the compiler and hand-coded assembly language functions to take advantage of the RISC-V extensions mandated by the application profiles. Further patches will be required to get the compiler/assembler and assembly language functions to actually generate and use these extensions.

2023-11-20all: add floating point option for ARM targetsLudi Rehak
This change introduces new options to set the floating point mode on ARM targets. The GOARM version number can optionally be followed by ',hardfloat' or ',softfloat' to select whether to use hardware instructions or software emulation for floating point computations, respectively. For example, GOARM=7,softfloat. Previously, software floating point support was limited to GOARM=5. With these options, software floating point is now extended to all ARM versions, including GOARM=6 and 7. This change also extends hardware floating point to GOARM=5. GOARM=5 defaults to softfloat and GOARM=6 and 7 default to hardfloat.

2023-09-05all: use ^TestName$ regular pattern for invoking a single testDmitri Shuralyov
Use ^ and $ in the -run flag regular expression value when the intention is to invoke a single named test. This removes the reliance on there not being another similarly named test to achieve the intended result. In particular, package syscall has tests named TestUnshareMountNameSpace and TestUnshareMountNameSpaceChroot that both trigger themselves setting GO_WANT_HELPER_PROCESS=1 to run alternate code in a helper process. As a consequence of overlap in their test names, the former was inadvertently triggering one too many helpers. Spotted while reviewing CL 525196. Apply the same change in other places to make it easier for code readers to see that said tests aren't running extraneous tests. The unlikely cases of -run=TestSomething intentionally being used to run all tests that have the TestSomething substring in the name can be better written as -run=^.*TestSomething.*$ or with a comment so it is clear it wasn't an oversight.

Additional tests and bug fixes realized while writing go.dev/doc/gotoolchain (CL 500775). - Handle go get toolchain@go1.22 (resolve to latest patch release, same as go get go@1.22). (See modload/query.go and gover/mod.go.) - Handle go get go@patch toolchain@patch. (See modload/query.go and gover/mod.go.) - Remove prefix-goVERSION-suffix form for toolchain name, standardizing on goVERSION-suffix. I have no good explanation for having two forms, so simplify to one. (See vendor and gover.) - Fail toolchain downloads when GOSUMDB=off. Because toolchain downloads cannot always be predicted (especially during switching rather than selection), they cannot be listed in go.sum. We rely on the checksum database for integrity of the download, especially if proxied. If the checksum database is disabled, this integrity check won't happen, so fail toolchain downloads. (See modfetch/sumdb.go and script/gotoolchain_net.txt) - Use names from documentation in package toolchain (Select, Switch; SwitchTo renamed to Exec to avoid both names; reqs.go renamed to switch.go; toolchain.go renamed to select.go.) - Make "go env GOTOOLCHAIN" and "go env -w GOTOOLCHAIN" work even when GOTOOLCHAIN is misconfigured. (See special case at top of Select in select.go.) - Clarify what goInstallVersion does (report whether this is go install or go run pkg@version) and explain the potential version switch more clearly. Use the Switcher directly instead of reimplementing it. (See select.go.) - Document go@ and toolchain@ forms in go help get, linking to go.dev/doc/toolchain.

2023-06-03cmd/go: maintain go and toolchain lines in go.workRuss Cox
go work init / sync / use need to maintain the invariant that the go version and toolchain in go.work are up-to-date with respect to the modules in the workspace. go get also preserves the invariant when running in a module. go work use (including with no arguments) reestablishes the invariant. Replaces the ToolchainTrySwitch func in PackageOpts with a new gover.Switcher interface implemented by toolchain.Switcher. Until now, the basic sketch of a particular phase of the go command has been to call base.Error repeatedly, to report as many problems as possible, and then call base.ExitIfErrors at strategic places where continuing in the presence of errors is no longer possible. A Switcher is similar: you call sw.Error repeatedly and then, when all the errors from a given phase have been identified, call sw.Switch to potentially switch toolchains, typically before calling base.ExitIfErrors. One effect of the regularization of errors reported by the modload.loader is to add a "go: " prefix to errors showing import stacks. That seems fine. For #57001.

2023-03-06cmd/go: support multiple main packages with -pgo=autoCherry Mui
In -pgo=auto mode, the go command finds a profile named default.pgo in the main package's directly, and if found, use it as the profile for the build. Currently we only support a single main package when -pgo=auto is used. When multiple main packages are included in a build, they may have different default profiles (or some have profiles whereas some don't), so a common dependent package would need to be built multiple times, with different profiles (or lack of). This CL handles this. To do so, we need to split (unshare) the dependency graph so they can attach different profiles. Fixes #58099.

2023-02-27cmd/go: convert mkalldocs.sh to a Go programBryan C. Mills
mkalldocs.sh required a Unix shell, making it less accessible for contributors on Windows. It also used a substantially different codepath to regenerate the file than the one used to check the file for staleness, making failures in TestDocsUpToDate more complex to diagnose. We can solve both of those problems by using the same technique as in checkScriptReadme: use the test itself as the generator to update the file. The test is already written in Go, the test binary already knows how to mimic the 'go' command, and this approach brings the difference between the test and the generator down to a single flag check. Updates #26735.
