Crash Handling System
|
||
|
|
=====================
|
||
|
|
|
||
|
|
Cutter uses `Breakpad <https://github.com/google/breakpad>`__ as backend
|
||
|
|
for crash handling.
|
||
|
|
|
||
|
|
Crash Handling System is disabled by default to do not interfere developers from debugging.
|
||
|
|
To enable this system there is building option ``CUTTER_ENABLE_CRASH_REPORTS``.
|
||
|
|
|
||
|
|
Solution description
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
There are only 2 source files:
|
||
|
|
|
||
|
|
* ``CrashHandler.h``
|
||
|
|
* ``CrashHandler.cpp``
|
||
|
|
|
||
|
|
And API is very simple: only one function - ``initCrashHandler()`` that enables Crash Handling System if
|
||
|
|
``CUTTER_ENABLE_CRASH_REPORTS`` is true, otherwise does nothing.
|
||
|
|
|
||
|
|
As soon as signal is raised ``crashHandler(int signum)`` is called with signal's code as argument.
|
||
|
|
This function first of all writes crash dump to OS's Temp directory to catch core and memory state
|
||
|
|
as it was at the crash moment.
|
||
|
|
|
||
|
|
Then crash dialog is shown:
|
||
|
|
|
||
|
|
.. image :: images/crash-dialog.png
|
||
|
|
|
||
|
|
If user chose to create crash dump, prepared dump is moved to directory specified by user.
|
||
|
|
And then success dialog is shown:
|
||
|
|
|
||
|
|
.. image :: images/success-dump-dialog.png
