Detailed Description

Header file for scheduler*.c.

Definition in file scheduler.h.

Enumeration Type Documentation

scheduler_types_t

enum scheduler_types_t

Scheduler type, we build an ordered list with those values from the parsed strings in Schedulers. The reason to do such a thing is so we can quickly and without parsing strings select the scheduler at anytime.

Function Documentation

scheduler_channel_doesnt_want_writes()

void scheduler_channel_doesnt_want_writes

(

channel_t *

chan

)

Mark a channel as no longer ready to accept writes.

Possible state changes:

• SCHED_CHAN_PENDING -> SCHED_CHAN_WAITING_TO_WRITE
• SCHED_CHAN_WAITING_FOR_CELLS -> SCHED_CHAN_IDLE

Definition at line 512 of file scheduler.c.

scheduler_channel_has_waiting_cells()

void scheduler_channel_has_waiting_cells

(

channel_t *

chan

)

Mark a channel as having waiting cells.

Possible state changes:

• SCHED_CHAN_WAITING_FOR_CELLS -> SCHED_CHAN_PENDING
• SCHED_CHAN_IDLE -> SCHED_CHAN_WAITING_TO_WRITE

Definition at line 548 of file scheduler.c.

scheduler_channel_wants_writes()

void scheduler_channel_wants_writes

(

channel_t *

chan

)

Mark a channel as ready to accept writes. Possible state changes:

• SCHED_CHAN_WAITING_TO_WRITE -> SCHED_CHAN_PENDING
• SCHED_CHAN_IDLE -> SCHED_CHAN_WAITING_FOR_CELLS

Definition at line 673 of file scheduler.c.

scheduler_conf_changed()

void scheduler_conf_changed

(

void

)

This is how the scheduling system is notified of Tor's configuration changing. For example: a SIGHUP was issued.

Definition at line 452 of file scheduler.c.

scheduler_free_all()

void scheduler_free_all

(

void

)

Free everything scheduling-related from main.c. Note this is only called when Tor is shutting down, while scheduler_t->free_all() is called both when Tor is shutting down and when we are switching schedulers.

Definition at line 484 of file scheduler.c.

scheduler_notify_networkstatus_changed()

void scheduler_notify_networkstatus_changed

(

void

)

Whenever we get a new consensus, this function is called.
