462b78fe70 misc/cgo/test: use fewer threads in TestSetgidStress in long mode
TestSetgidStress originally spawns 1000 threads for stress testing.
It caused timeout on some builders so CL 415677 reduced to 50 in
short mode. But it still causes flaky timeouts in longtest
builders, so reduce the number of threads in long mode as well.

Should fix #53641.

3e97294663 runtime/cgo: use frame address to set g0 stack bound
For a cgo binary, at startup we set g0's stack bounds using the
address of a local variable (&size) in a C function x_cgo_init and
the stack size from pthread_attr_getstacksize. Normally, &size is
an address within the current stack frame. However, when  it is
compiled with ASAN, it may be instrumented to __asan_stack_malloc_0
and the address may not live in the current stack frame, causing
the stack bound to be set incorrectly, e.g. lo > hi.

Using __builtin_frame_address(0) to get the stack address instead.

dcea1ee6e3 time: clarify documentation for allowed formats and add tests to prove them
The existing documentation for the time.Layout const states "Only these values
are recognized", but then doesn't include the numeric forms for month leading to
ambiguity and assumptions that may not be true. It's unclear, for example,
that space padding is only available for day of the month.

Finally I add tests to show the behaviors in specific scenarios.

c5da4fb7ac cmd/compile: make jump table symbol local
When using plugins, if the plugin and the main executable both
have the same function, and if it uses jump table, currently the
jump table symbol have the same name so it will be deduplicated by
the dynamic linker. This causes a function in the plugin may (in
the middle of the function) jump to the function with the same name
in the main executable (or vice versa). But the function may be
compiled slightly differently, because the plugin needs to be PIC.
Jumping from the middle of one function to the other will not work.
Avoid this problem by marking the jump table symbol local to a DSO.

Fixes #53989.

774fa58d1d A+C: delete AUTHORS and CONTRIBUTORS
In 2009, Google's open-source lawyers asked us to create the AUTHORS
file to define "The Go Authors", and the CONTRIBUTORS file was in
keeping with open source best practices of the time.

Re-reviewing our repos now in 2022, the open-source lawyers are
comfortable with source control history taking the place of the
AUTHORS file, and most open source projects no longer maintain
CONTRIBUTORS files.

To ease maintenance, remove AUTHORS and CONTRIBUTORS from all repos.

244c8b0500 cmd/cgo: allow cgo to pass strings or []bytes bigger than 1<<30
There's no real reason to limit to 1<<30 bytes. Maybe it would catch
some mistakes, but probably ones that would quickly manifest in other
ways.

We can't use the fancy new unsafe.Slice function because this code
may still be generated for people with 1.16 or earlier in their go.mod file.
Use unsafe shenanigans instead.

Fixes #53965

df38614bd7 test: use go tool from tree, not path
Some of our tests do exec.Command("go", "tool", "compile", ...) or
similar. That "go" is selected from PATH. When run.go is started
from the command line (but not from all.bash), the first "go" is whatever
happens to be first in the user's path (some random older version than
tip). We really want all these tests to use the "go" tool from the
source tree under test. Add GOROOT/bin to the front of the path to
ensure that the tools we use come from the source tree under test.

85a482fc24 runtime: revert to using the precomputed trigger for pacer calculations
Issue #53738 describes in detail how switching to using the actual
trigger point over the precomputed trigger causes a memory regression,
that arises from the fact that the PI controller in front of the
cons/mark ratio has a long time constant (for overdamping), so it
retains a long history of inputs.

This change, for the Go 1.19 cycle, just reverts to using the
precomputed trigger because it's safer, but in the future we should
consider moving away from such a history-sensitive smoothing function.

See the big comment in the diff and #53738 for more details.

Performance difference vs. 1.18 after this change:
https://perf.golang.org/search?q=upload:20220714.15

Fixes #53738.

atomic.Int64 has special logic in the compiler to ensure it's 8-byte
aligned on 32-bit architectures. The equivalent logic is missing in
go/types, which means the compiler and go/types can come to different

Fix this by mirroring the compiler's logic into go/types.

Within a single module we expect all needed checksums to have already
been recorded by a previous call to 'go get' or 'go mod tidy' in that
module. However, when we combine multiple modules in a workspace, they
may upgrade each other's dependencies, so a given module might be
upgraded above the highest version recorded in the individual go.sum
files for the workspace modules.

Since the checksums might not be present in individual go.sum files,
record them in go.work.sum.

f71f3d1b86 misc/cgo/testshared: run tests only in GOPATH mode
-buildmode=shared installs shared libraries into GOROOT
and expects to reuse them across builds.
Builds in module mode, however, each have their own set of
dependencies (determined by the module's requirements), so in general
cannot share dependencies with a single GOROOT.

Ideally in the long term we would like to eliminate -buildmode=shared
entirely (see #47788), but first we need a replacement for the subset
of use-cases where it still works today.

In the meantime, we should run these tests only in GOPATH mode.
Non-main packages in module mode should not be installed to
GOPATH/pkg, but due to #37015 they were installed there anyway,
and this test heavily relies on installing non-main packages.

For #37015.

Non-main packages in module mode should not be installed to

This change switches the 'go install' command in createHeaders to
instead use 'go build' (with an extension determined by the install
target for 'runtime/cgo', which is well-defined at least for the
moment), and switches TestCachedInstall (which appears to be
explicitly testing 'go install') to explicitly request GOPATH mode
(which provides a well-defined install target for the library).

This change follows a similar structure to CL 416954.

c006b7ac27 runtime: clear timerModifiedEarliest when last timer is deleted
timerModifiedEarliest contains the lowest possible expiration for a
modified earlier timer, which may be earlier than timer0When because we
haven't yet updated the heap. Note "may", as the modified earlier timer
that set timerModifiedEarliest may have since been modified later or
deleted.

We can clear timerModifiedEarliest when the last timer is deleted
because by definition there must not be any modified earlier timers.

Why does this matter? checkTimersNoP claims that there is work to do if
timerModifiedEarliest has passed, causing findRunnable to loop back
around to checkTimers. But the code to clean up timerModifiedEarliest in
checkTimers (i.e., the call to adjusttimers) is conditional behind a
check that len(pp.timers) > 0.

Without clearing timerModifiedEarliest, a spinning M that would
otherwise go to sleep will busy loop in findRunnable until some other
work is available.

Note that changing the condition on the call to adjusttimers would also
be a valid fix. I took this approach because it feels a bit cleaner to
clean up timerModifiedEarliest as soon as it is known to be irrelevant.

Fixes #51654.
