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:
|
|
|

|
|
|
1515 UserDebuggerHotKey
|

|
|
|
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.

2585 think. In particular, QUIT checking will query and remove

2586 events, including keyboard events, from the queue. (QUIT is
|
|
|
2587 definitely invoked from TO_INTERNAL_FORMAT().) If we do

2588 this recursively anywhere in the following code, it will
|
|

2589 mess certain things up -- in particular, the OS-provided

|

|
2594 triggered only every 1/4 second, why is it getting
|
|
|
2595 consistently triggered here? I saw the problem
|
|
|
2596 consistently. Answer: It appears that, currently,
|
|
|
2597 sometimes the code to pump messages is wrapped with
|
|
|
2598 begin_dont_check_for_quit() and sometimes it isn't. (####
|
|
|
2599 FIX THIS SHIT!) cmdloop.c, for example, has it, but not
|
|
|
2600 everywhere. The current games with avoiding QUIT mean that
|
|
|
2601 the 1/4-second timer consistently fires while
|
|
|
2602 dont_check_for_quit is set [which causes the quit check to
|
|
|
2603 get deferred but the flag is still on], and so the next
|
|
|
2604 time it's unset and we call QUIT is *right here*.
|
|
|
2605
|
|
|
2606 In my stderr-proc ws I majorly cleaned up the whole shit by
|
|
|
2607 just wrapping all the entry points in dont_check_for_quit.
|
|
|
2608 This fixed the remaining bugs with C-g getting interpreted
|
|
|
2609 wrong.)

|
2610

2611 #### We should probably wrap this whole function in
|
|
|
2612 begin_dont_check_for_quit(); but then we should set this
|
|
|
2613 back to 0 when handling a menu callback, which gets invoked
|
|
|
2614 from within this function, specifically from
|
|
|
2615 DefWindowProc(). (We already do the latter in my new
