Goal
Fix a data race detected by ThreadSanitizer.
Changeset
Wraps access to
nextFileNumber
in a@synchronized (self)
block to prevent simultaneous read and write.Skips
testCrashReportWriterConcurrency
when ThreadSanitizer is enabled because suspending threads causes deadlocks in TSan's code (which uses locking primitives.)Testing
Reproduced issue by running
BugsnagBreadcrumbsTest
with ThreadSanitizer enabled, confirmed that data race is no longer reported.
