CL 294430 made packages in std and cmd modules use Go 1.17 gofmt format,
adding //go:build lines. This change applies the same formatting to some
more packages that 'go fmt' missed (e.g., syscall/js, runtime/msan), and
everything else that is easy and safe to modify in bulk.
Consider the top-level test directory, testdata, and vendor directories
out of scope, since there are many files that don't follow strict gofmt
formatting, often for intentional and legitimate reasons (testing gofmt
itself, invalid Go programs that shouldn't crash the compiler, etc.).
That makes it easy and safe to gofmt -w the .go files that are found
with gofmt -l with aforementioned directories filtered out:
$ gofmt -l . 2>/dev/null | \
grep -v '^test/' | \
grep -v '/testdata/' | \
grep -v '/vendor/' | wc -l
51
None of the 51 files are generated. After this change, the same command
prints 0.
For #41184.

The iOS exec wrapper uses ios-deploy to set up a device, install
the wrapped app, and start a lldb session to run it. ios-deploy is
not built to be scripted, as can be seen from the brittle way it is
driven by the Go wrapper. There are many timeouts and comments such
as
"
// lldb tries to be clever with terminals.
// So we wrap it in script(1) and be clever
// right back at it.
"
This CL replaces the use of ios-deploy with a lldb driver script in
Python. lldb is designed to be scripted, so apart from getting rid
of the ios-deploy dependency, we gain:
- No timouts and scripting ios-deploy through stdin and parsing
stdout for responses.
- Accurate exit codes.
- Prompt exits when the wrapped binary fails for some reason. Before,
the go test timeout would kick in to fail the test.
- Support for environment variables.
- No noise in the test output. Only the test binary output is output
from the wrapper.
We have to do more work with the lldb driver: mounting the developer
image on the device, running idevicedebugserverproxy and installing
the app. Even so, the CL removes almost as many lines as it adds.
Furthermore, having the steps split up helps to tell setup errors
from runtime errors.

To enable the exec wrapper go_darwin_arm_exec.go to run binaries
on iOS devices, the GOIOS_DEV_ID variable needs to be set to a code
signing identity. The program detect.go attempts to detect suitable
values for GOIOS_DEV_ID (along with GOIOS_APP_ID and GOIOS_TEAM_ID).
Before this change, detect.go would use "security find-identity
-p codesigning -v" to list all available identities for code signing
and pick the first one with "iPhone Developer" in its name. However,
that pick might be invalid since if it was replaced by an identity
issued later.
For example, on the mobile builder:
$ security find-identity -p codesigning -v
1) 0E251DE41FE4490574E475AC320B47F58D6D3635 "lldb_codesign"
2) 0358588D07AA6A19478981BA405F40A97F95F187 "iPhone Developer: xxx@xxx (2754T98W8E)"
3) FC6D96F24A3223C98BF7A2C2C5194D82E04CD23E "iPhone Developer: xxx@xxx (2754T98W8E)"
3 valid identities found
In this case, the identity 0358588D07AA6A19478981BA405F40A97F95F187
is picked by detect.go even though it has been invalidated by
FC6D96F24A3223C98BF7A2C2C5194D82E04CD23E.
Instead of attempting to find an identity from the "security
find-identity" list, use the identity from the CommonName in the
embedded certificate in the provisioning file. The CommonName only
lists the identity name (iPhone Developer: xxx@xxx (2754T98W8E)),
not the fingerprint (FC6D96F24A3223C98BF7A2C2C5194D82E04CD23E), but
fortunately the codesign tool accepts both.
Identity names may not be unique, as demonstrated by the example,
but that will result in an ambiguity error at codesigning instead of
a more obscure error about an invalid identity when
go_darwin_arm_exec.go runs a binary.
The fix is then to delete the invalid identity from the system
keychain.
While here, find all connected devices instead of the first connected
and only consider provision files that covers them all. This matters
for the mobile builder where two devices are connected.

These days, the current working directory is passed from the wrapper
to the runtime through a special entry in the app metadata and the
SIGINT handshake is not necessary anymore.

When running multiple iOS builds on the same host, GOIOS_DEVICE_ID
is used to distinguish the devices. To improve support,
- Only restart the particular device when invoking iostest.bash
with the -restart flag.
- Make the exec wrapper lock file per-device.

The iOS test harness was recently changed in response to lldb bugs
to replace breakpoints with the SIGUSR2 signal (CL 34926), and to
pass the current directory in the test binary arguments (CL 35152).
Both the signal sending and working directory setup is done from
the go test driver.
However, the new method doesn't work with tests where a C program is
the test driver instead of go test: the current working directory
will not be changed and SIGUSR2 is not raised.
Instead of copying that logic into any C test program, rework the
test harness (again) to move the setup logic to the early runtime
cgo setup code. That way, the harness will run even in the library
build modes.
Then, use the app Info.plist file to pass the working
directory, removing the need to alter the arguments after running.
Finally, use the SIGINT signal instead of SIGUSR2 to avoid
manipulating the signal masks or handlers.
Fixes the testcarchive tests on iOS.
With this CL, both darwin/arm and darwin/arm64 passes all.bash.
This CL replaces CL 34926, CL 35152 as well as the fixup CL
35123 and CL 35255. They are reverted in CLs earlier in the
relation chain.

Tests that use TestMain might never call m.Run(), and simply return
from TestMain. In that case, the iOS test harness never sees the
PASS from the testing framework and assumes the test failed.
Allow an exit with exit code 0 to also mean test success, thereby
fixing the objdump test on iOS.

If -test.timeout is not specified to go test, it will time out after
a default 10 minutes.
The iOS exec wrapper also contains a fail safe timeout mechanism for
a stuck device. However, if no explicit -test.timeout is specified,
it will use a timeout of 0, plus some constant amount.
Use the same default timeout in the exec wrapper as for go test,
10 minutes.

The iOS exec wrapper use the constant bundle id "golang.gotest" for
running Go programs on iOS. However, that only happens to work on
the old iOS builders where their provisioning profile covers
that bundle id.
Expand the detection script to list all available provisioning
profiles for the attached device and include the bundle id in the
GOIOS_APP_ID environment variable.
To allow the old builders to continue, the "golang.gotest" bundle
id is used as a fallback if only the app id prefix is specified in
GOIOS_APP_ID.

The working directory is now adjusted to match the typical Go test
working directory in main, as the old trick for adjusting earlier
stopped working with the latest version of LLDB bugs.
That means the small number of places where testdata files are
read before main is called no longer work. This CL adjusts those
reads to happen after main is called. (This has the bonus effect of
not reading some benchmark testdata files in all.bash.)
Fixes compress/bzip2, go/doc, go/parser, os, and time package

Another change in behvaior (bug) in LLDB. Despite the fact that
LLDB can dump the symtab of our test binaries and show the function
addresses, it can no longer call the functions. This means the chdir
trick on signal is failing.
This CL uses a new trick. For iOS, the exec script passes the change
in directory as an argument, and it is processed early by the test
harness generated by cmd/go.

The iOS test harness has set a breakpoint early in the life of Go
programs so that it can change the current working directory using
information only available from the host debugger. Somewhere in the
upgrade to iOS 10 / XCode 8.2, breakpoints stopped working. This
may be an LLDB bug, or a bug in the ios-deploy LLDB scripts, it's
not clear.
Work around the problem by giving up on breakpoints. Instead, early
in the life of every test binary built for iOS, send (and ignore) a
SIGUSR2 signal. The debugger will catch this, giving the script
go_darwin_arm_exec a chance to change the working directory.
For the iOS builders.
