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