2025-06-27runtime: remove arbitrary 5-second timeout in TestNeedmDeadlockCherry Mui
The NeedmDeadlock test program currently has a 5-second timeout, which is sort of arbitrary. It is long enough in regular mode (which usually takes 0.0X seconds), but not quite so for configurations like ASAN. Instead of using an arbitrary timeout, just use the test's deadline. The test program is invoked with testenv.Command, which will send it a SIGQUIT before the deadline expires. Fixes #56420 (at least for the asan builder).

2021-12-13all: gofmt -w -r 'interface{} -> any' srcRuss Cox
And then revert the bootstrap cmd directories and certain testdata. And adjust tests as needed. Not reverting the changes in std that are bootstrapped, because some of those changes would appear in API docs, and we want to use any consistently. Instead, rewrite 'any' to 'interface{}' in cmd/dist for those directories when preparing the bootstrap copy. A few files changed as a result of running gofmt -w not because of interface{} -> any but because they hadn't been updated for the new //go:build lines. Fixes #49884.

2020-10-28runtime: block signals in needm before allocating MIan Lance Taylor
Otherwise, if a signal occurs just after we allocated the M, we can deadlock if the signal handler needs to allocate an M itself.
