36 * System interrupt and critical section handling
37 *
38 * There are two types of interrupts that a running backend needs to accept
39 * without messing up its state: QueryCancel (SIGINT) and ProcDie (SIGTERM).
40 * In both cases, we need to be able to clean up the current transaction
41 * gracefully, so we can't respond to the interrupt instantaneously ---
42 * there's no guarantee that internal data structures would be self-consistent
43 * if the code is interrupted at an arbitrary instant. Instead, the signal
44 * handlers set flags that are checked periodically during execution.
45 *
46 * The CHECK_FOR_INTERRUPTS() macro is called at strategically located spots
47 * where it is normally safe to accept a cancel or die interrupt. In some
48 * cases, we invoke CHECK_FOR_INTERRUPTS() inside low-level subroutines that
49 * might sometimes be called in contexts that do *not* want to allow a cancel
50 * or die interrupt. The HOLD_INTERRUPTS() and RESUME_INTERRUPTS() macros
51 * allow code to ensure that no cancel or die interrupt will be accepted,
52 * even if CHECK_FOR_INTERRUPTS() gets called in a subroutine. The interrupt
53 * will be held off until CHECK_FOR_INTERRUPTS() is done outside any
54 * HOLD_INTERRUPTS() ... RESUME_INTERRUPTS() section.
55 *
56 * There is also a mechanism to prevent query cancel interrupts, while still
57 * allowing die interrupts: HOLD_CANCEL_INTERRUPTS() and
58 * RESUME_CANCEL_INTERRUPTS().
59 *
60 * Note that ProcessInterrupts() has also acquired a number of tasks that
61 * do not necessarily cause a query-cancel-or-die response. Hence, it's
62 * possible that it will just clear InterruptPending and return.
63 *
64 * INTERRUPTS_PENDING_CONDITION() can be checked to see whether an
65 * interrupt needs to be serviced, without trying to do so immediately.
66 * Some callers are also interested in INTERRUPTS_CAN_BE_PROCESSED(),
67 * which tells whether ProcessInterrupts is sure to clear the interrupt.
68 *
69 * Special mechanisms are used to let an interrupt be accepted when we are
70 * waiting for a lock or when we are waiting for command input (but, of
71 * course, only if the interrupt holdoff counter is zero). See the
72 * related code for details.
73 *
74 * A lost connection is handled similarly, although the loss of connection
75 * does not raise a signal, but is detected when we fail to write to the
76 * socket. If there was a signal for a broken connection, we could make use of
77 * it by setting ClientConnectionLost in the signal handler.
78 *
79 * A related, but conceptually distinct, mechanism is the "critical section"
80 * mechanism. A critical section not only holds off cancel/die interrupts,
81 * but causes any ereport(ERROR) or ereport(FATAL) to become ereport(PANIC)
82 * --- that is, a system-wide reset is forced. Needless to say, only really
83 * *critical* code should be marked as a critical section! Currently, this
84 * mechanism is only used for XLOG-related code.
