pub struct DebugSynchronousProxy { /* private fields */ }

Implementations

impl DebugSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<DebugEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn compact( &self, ___deadline: MonotonicInstant, ) -> Result<DebugCompactResult, Error>

Forces a compaction.

pub fn delete_profile( &self, volume: &str, profile: &str, ___deadline: MonotonicInstant, ) -> Result<DebugDeleteProfileResult, Error>

Deletes a recorded profile from a volume. Fails if the volume isn’t mounted or there is active profile recording or replay.

pub fn record_and_replay_profile( &self, volume: Option<&str>, profile: &str, duration_secs: u32, ___deadline: MonotonicInstant, ) -> Result<DebugRecordAndReplayProfileResult, Error>

Begins recording a profile for a named volume for up to the given duration in seconds. If a profile already exists under the given name then it will begin replaying it as well. Fails if the volume isn’t mounted or there is active profile recording or replay on the volume. Page faults for objects that do not get opened by a caller during the recording period will will be filtered out of the profile.

This “record-while-replaying” strategy is meant to support boot-profiling in an environment where we don’t explicitly know when the system has updated. By recording during replay and filtering objects without open events, Fxfs drops dead/replaced objects to refresh the profile.

pub fn replay_xor_record_profile( &self, volume: &str, profile: &str, duration_secs: u32, ___deadline: MonotonicInstant, ) -> Result<DebugReplayXorRecordProfileResult, Error>

Replays a profile if one exists, and only records if one does not exist. Fails if the volume isn’t mounted or there is active profile recording or replay on the volume.

This profile method is meant to support app launch profiling. These profiles do not filter entries based on Open events since outside of the boot process objects may already be opened or cached in overlays like Starnix.

pub fn stop_profile_tasks( &self, ___deadline: MonotonicInstant, ) -> Result<DebugStopProfileTasksResult, Error>

Stops all profile recording and replay activity. Ongoing recordings are completed and persisted.
