The change https://golang.org/cl/12192 changed the get code to use the
list of package imports, not the computed list of dependencies, as the
computed list could be out of date if the package changed when using
go get -u. Computing the dependency list would skip an import of "C",
but that would still be on the package import list. This changes the
code to skip "C" when walking the import list.
No test--the best test would be to add an import of "C" to
github.com/rsc/go-get-issue-9224-cmd for TestGoGetUpdate.
Fixes#11738.

This fix only works on Git 2.3.0 and later.

things to get /dev/tty invalidated during the exec, but I'd really
rather not. And on Windows, Git opens "CONIN$" and "CONOUT$"

When GOROOT_FINAL is set when running all.bash, the tests are run

In cmd/go/go_test.go we were explicitly removing GOROOT from the
environment, causing tests that did not themselves explicitly set
GOROOT to fail. There was no need to explicitly remove GOROOT, so
don't do it. If people choose to run "go test cmd/go" with a bad
GOROOT, that is their own lookout.
In the runtime GDB test, the linker has told gdb to find the support
script in GOROOT_FINAL, which will fail. Check for that case, and
skip the test when we see it.

But growslice still interpreted the argument as the number of new elements,

to the next malloc block size). At the time, I had intended to change
the other callers to use the new cap as well, but it's too late for that.

There are two conditions to worry about:
1) The shift count cannot be negative. Since the evaluator uses unsigned
arithmetic throughout, this means checking that the high bit of
the shift count is always off, which is done by converting to int64
and seeing if the result is negative.
2) For right shifts, the value cannot be negative. We don't want a
high bit in the value because right shifting a value depends on the
sign, and for clarity we always want unsigned shifts.
Next step is to build some testing infrastructure for the parser.

The test was translated from shell incorrectly,
and it depended on having hg installed, which
may not be the case.
Moved repo to GitHub, updated code, and fixed
go list ... command to be expected to succeed.
Fixes test for #8181.

Most important: skip test on darwin/arm64 for unclear reasons.
First cut at the test missed this feature of go doc: when asking for
the docs for a type, include any function that looks like it constructs
a that type as a return value.

nacl is really giving a hard time. avoid all external dependencies in the test.
Worked with trybots, failed in the build. No explanation, but this should fix it.

Refactor main a bit to make it possible to run tests without an exec every time.
(Makes a huge difference in run time.)
Add a silver test. Not quite golden, since it looks for pieces rather than the
full output, and also includes tests for what should not appear.
Fixes#10920.

When GO15VENDOREXPERIMENT=1 is in the environment,
this CL changes the resolution of import paths according to
the Go 1.5 vendor proposal:
If there is a source directory d/vendor, then,
when compiling a source file within the subtree rooted at d,
import "p" is interpreted as import "d/vendor/p" if that exists.
When there are multiple possible resolutions,
the most specific (longest) path wins.
The short form must always be used: no import path can
contain “/vendor/” explicitly.
Import comments are ignored in vendored packages.
The goal of these changes is to allow authors to vendor (copy) external
packages into their source trees without any modifications to the code.
This functionality has been achieved in tools like godep, nut, and gb by
requiring GOPATH manipulation. This alternate directory-based approach
eliminates the need for GOPATH manipulation and in keeping with the
go command's use of directory layout-based configuration.
The flag allows experimentation with these vendoring semantics once
Go 1.5 is released, without forcing them on by default. If the experiment
is deemed a success, the flag will default to true in Go 1.6 and then be
removed in Go 1.7.

The -importmap option takes an argument of the form old=new
and specifies that import "old" should be interpreted as if it said
import "new". The option may be repeated to specify multiple mappings.
This option is here to support the go command's new -vendor flag.
