Module supervisor 

Structs

SupervisorConfig

The full configuration used by the zcashd-compat supervisor task.

Enums

ChildOutcome 🔒

Constants

PEER_SELECTION_OPTIONS 🔒

zcashd options that add P2P peers and accumulate across the command line, so the supervisor’s own -connect cannot override them.

SUPERVISOR_ACTIVE_METRIC 🔒

SUPERVISOR_DISABLED_METRIC 🔒

SUPERVISOR_EXHAUSTED_METRIC 🔒

Statics

SUPERVISED_ZCASHD_PID 🔒

The pid of the currently running supervised zcashd child, or 0 when none.

Functions

is_command_resolvable

Returns true if the given command path is resolvable as an executable.

is_executable 🔒

Returns true when path points to an executable regular file.

reject_peer_selection_extra_args

Rejects zcashd_extra_args entries that would change which peers the supervised zcashd talks to.

restart_backoff_delay 🔒

Calculates capped exponential restart backoff from the base delay and consecutive exit count.

run

Runs the zcashd-compat zcashd supervisor until shutdown.

sanitize_child_log_line 🔒

Returns a sanitized log line with ANSI escape/control noise removed.

set_supervision_active_metrics 🔒

set_supervision_config_disabled_metrics

Sets metrics for zcashd-compat mode when zcashd supervision is intentionally disabled.

set_supervision_inactive_metrics 🔒

set_supervision_unexpectedly_disabled_metrics

Sets metrics for zcashd-compat mode when supervision has unexpectedly stopped.

should_reset_restart_count 🔒

Returns true when a child ran long enough to make previous failures stale.

spawn_log_task 🔒

Forwards a child output stream into Zebra logs under zcashd_compat.zcashd.

spawn_zcashd 🔒

Spawns zcashd with zcashd-compat arguments and connects child output streams.

terminate_abandoned_zcashd

Terminates a supervised zcashd child that the supervisor task never got to shut down, blocking the calling thread.

terminate_child 🔒

Attempts graceful termination of the zcashd-compat child process.

wait_for_child_or_shutdown 🔒

Waits until either a shutdown request arrives or the child exits.

wait_for_delay_or_shutdown 🔒

Waits for delay to elapse, returning true if shutdown is requested first.
