The recent metrics-on-by-default switch is causing issues for folks on uWSGI in prefork mode.
In other places where we use threads we always create the thread on demand, but in the metrics code we create a thread right away (so presumably before the process is forked). This PR aligns the behavior.
Additionally, add a small check like we have in the profiler for potential race conditions when spawning the flusher thread.
General Notes
Thank you for contributing to
sentry-python!Please add tests to validate your changes, and lint your code using
tox -e linters.Running the test suite on your PR might require maintainer approval. Some tests (AWS Lambda) additionally require a maintainer to add a special label to run and will fail if the label is not present.
For maintainers
Sensitive test suites require maintainer review to ensure that tests do not compromise our secrets. This review must be repeated after any code revisions.
Before running sensitive test suites, please carefully check the PR. Then, apply the
Trigger: tests using secretslabel. The label will be removed after any code changes to enforce our policy requiring maintainers to review all code revisions before running sensitive tests.
