check / check (push) Failing after 2s
script/test-race runs go test -race in a digest-pinned Debian golang image that has gcc, since the detector needs cgo and the build keeps it off. The checkout is mounted read-only and the container is removed afterwards. The tests run as the calling user, or as nobody when that is root, so the tests that make a file unreadable still see the read fail. It is not part of make check. The detector found no races. Model: opus-5-5

# script/test-race: run the test suite under the race detector. Not part

# of script/check.

|
|
# The race detector needs cgo and a C compiler, which the host build
|
|
# never uses, so the tests run in a golang image that has gcc. The
|
|
# checkout is mounted read-only, so the docker daemon must be local. The
|
|
# container starts with empty caches every time: each run downloads the
|
|
# dependencies and compiles them with the detector, which needs the
|
|
# network and takes minutes.
|
|
#
|
|
# The tests run as the calling user, never as root: several of them make
|
|
# a file unreadable and expect reading it to fail, and root reads it
|
|
# anyway. When the caller is root they run as nobody, and then the
|
|
# checkout must be readable by other users. Neither user has a home
|
|
# directory in the image, so HOME is /tmp, where Go puts its build cache.
