installStallSentinelDiskSink function

void installStallSentinelDiskSink()

Installs the disk sink for stallDumpSink (the pure side's seam). Idempotent. installProviderStallForensics (conn_trace_io.dart) calls this; hosts that want dumps without the conn-trace stderr lines can call it directly.

Implementation

void installStallSentinelDiskSink() {
  stallDumpSink ??= writeStallDumpToDisk;
}
