2019-04-23cmd/go: add env -w and env -u to set and unset default env varsRuss Cox
Setting environment variables for go command configuration is too difficult and system-specific. This CL adds go env -w, to change the default settings more easily, in a portable way. It also adds go env -u, to unset those changes. See https://golang.org/design/30411-env for details. Fixes #30411.

2018-08-01cmd/go: add $GOFLAGS environment variableRuss Cox
People sometimes want to turn on a particular go command flag by default. In Go 1.11 we have at least two different cases where users may need this. 1. Linking can be noticeably slower on underpowered systems due to DWARF, and users may want to set -ldflags=-w by default. 2. For modules, some users or CI systems will want vendoring always, so they want -getmode=vendor (soon to be -mod=vendor) by default. This CL generalizes the problem to “set default flags for the go command.” $GOFLAGS can be a space-separated list of flag settings, but each space-separated entry in the list must be a standalone flag. That is, you must do 'GOFLAGS=-ldflags=-w' not 'GOFLAGS=-ldflags -w'. The latter would mean to pass -w to go commands that understand it (if any do; if not, it's an error to mention it). For #26074. For #26318. Fixes #26585.

2017-10-25build: move final steps of make.bash, make.bat, make.rc into cmd/distRuss Cox
This CL expands the job of "dist bootstrap" to be "finish make.bash". I need to change that logic in upcoming CLs related to cmd/go changes, and I'd rather not change it in three places in three different shell script languages.

2015-02-23[dev.cc] cmd/go: fix expansion of 'std', add 'cmd'Russ Cox
The wildcard 'std' is defined in documentation to be all the packages in the Go standard library. It has also historically matched commands in the main repo, but as we implement core commands in Go, that becomes problematic. We need a wildcard that means just the library, and since 'std' is already documented to have that definition, make it so. Add a new wildcard 'cmd' for the commands in the main repo ($GOROOT). Commands that want both can say 'std cmd' (or 'cmd std') to get the effect of the old 'std'. Update make.bash etc to say both std and cmd most of the time. Exception: in race.bash, do not install race-enabled versions of the actual commands. This avoids trying to write binaries while using them, but more importantly it avoids enabling the race detector and its associated memory overhead for the already memory-hungry compilers.

2015-01-21[dev.cc] build: do not 'clean -i std' between dist and go_bootstrapRuss Cox
Executing 'clean -i std' removes installed Go programs, including the toolchain binaries we need for building. It's not clear why the 'clean -i std' is here in the first place. cmd/dist just removed the entire pkg tree, so everything is new. The only reason for 'clean -i std' would be if you don't trust that dist compiled the packages properly. If that's true for some reason, we can fix cmd/dist, or add -a to the install commands that follow. Perhaps clean -i std should not remove tools, or perhaps std should not expand to any tools. Not sure. Also remove banner from make.bat and make.rc that was already removed from make.bash. cmd/dist prints it now. Also fix array size error in liblink/objfile.c. Fixes dev.cc build.
