| 1481 | |
| 1482 Microsoft says: | |
| 1483 | |
| 1484 (Knowledge Base Q130667, PRB: F12 Causes Hard-Coded Breakpoint | |
| 1485 Exception When Debugging) | |
| 1486 | |
| 1487 CAUSE | |
| 1488 | |
| 1489 When the F12 key is pressed and the application in focus is being | |
| 1490 debugged, Windows NT calls a function similar to DebugBreak(), | |
| 1491 which executes a hard coded breakpoint instruction. The integrated | |
| 1492 debugger then traps the exception generated by this instruction. | |
| 1493 | |
| 1494 This behavior is intentional and occurs with other debuggers such | |
| 1495 as WinDbg from the Windows 32-bit SDK. | |
| 1496 | |
| 1497 RESOLUTION | |
| 1498 | |
| 1499 While there is no way to disable this functionality, it doesn't | |
| 1500 affect the application that's being debugged other than to pause | |
| 1501 debugging and change focus. You can continue debugging by pressing | |
| 1502 the F5 key. | |
| 1503 | |
| 1504 This can be annoying if you have an application that heavily uses | |
| 1505 the F12 key, so you may want to temporarily assign another key to | |
| 1506 handle the F12 key functionality in your program when debugging. | |
| 1507 | |
| 1508 STATUS | |
| 1509 | |
| 1510 This behavior is by design. | |
| 1511 | |
| 1512 | |
| 1513 However, elsewhere I found this: | |
| 1514 | |
| 1515 UserDebuggerHotKey | |
| 1516 HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug | |
| 1517 | |
| 1518 Data type Range Default value | |
| 1519 REG_DWORD 0x0 - 0xFF 0x0 | |
| 1520 | |
| 1521 Description | |
| 1522 | |
| 1523 Specifies the key that, when pressed, establishes a breakpoint in | |
| 1524 code being debugged. | |
| 1525 | |
| 1526 The debugger interrupts code processing at the breakpoint so the | |
| 1527 programmer can examine a suspected problem. | |
| 1528 | |
| 1529 The key specified in this value only sets a breakpoint. It does | |
| 1530 not invoke the debugger (the debugger must be running before the | |
| 1531 key is pressed) and it does not switch the debugger to single-step | |
| 1532 mode. | |
| 1533 | |
| 1534 The value of this entry is a keyboard scan code. The default | |
| 1535 value, 0x0, represents the F12 key on a 101-key keyboard or the - | |
| 1536 (hyphen, VK_SUBTRACT) key on an 82-key keyboard. | |

| 2582 think. In particular, QUIT checking will query and remove | |
| 2583 events, including keyboard events, from the queue. (QUIT is | |
| 2584 definitely invoked from TO_INTERNAL_FORMAT().) If we do | |
| 2585 this recursively anywhere in the following code, it will | |
| 2586 mess certain things up -- in particular, the OS-provided | |
| 2587 sticky modifier code available as part of the accessibility | |
| 2588 package. | |
| 2589 | |
| 2590 (Academic question: If QUIT checking is supposed to be | |
| 2591 triggered only every 1/4 second, why is it getting | |
| 2592 consistently triggered here? I saw the problem | |
| 2593 consistently. Answer: It appears that, currently, | |
| 2594 sometimes the code to pump messages is wrapped with | |
| 2595 begin_dont_check_for_quit() and sometimes it isn't. (#### | |
| 2596 FIX THIS SHIT!) cmdloop.c, for example, has it, but not | |
| 2597 everywhere. The current games with avoiding QUIT mean that | |
| 2598 the 1/4-second timer consistently fires while | |
| 2599 dont_check_for_quit is set [which causes the quit check to | |
| 2600 get deferred but the flag is still on], and so the next | |
| 2601 time it's unset and we call QUIT is *right here*. | |
| 2602 | |
| 2603 In my stderr-proc ws I majorly cleaned up the whole shit by | |
| 2604 just wrapping all the entry points in dont_check_for_quit. | |
| 2605 This fixed the remaining bugs with C-g getting interpreted | |
| 2606 wrong.) | |
| 2607 | |
| 2608 #### We should probably wrap this whole function in | |
| 2609 begin_dont_check_for_quit(); but then we should set this | |
| 2610 back to 0 when handling a menu callback, which gets invoked | |
| 2611 from within this function, specifically from | |
| 2612 DefWindowProc(). (We already do the latter in my new | |
| 2613 stderr-proc ws, because in that ws next_event_internal() | |
