* Fixing debuggerd header output.Brigid Smith2014-06-231-3/+2
| | | | | | PID and TID output line was missing. Change-Id: I609af5727bc22ea0b97f3975ddb3cf0102910bc2
* Maps output now marks the fault address location.Brigid Smith2014-06-201-4/+13
| | | | | | | | If the fault address is not within a mapped region, it logs an error message after the output. Otherwise, it prefixes the location of the fault address with "--->" to make it easier to locate. Change-Id: I330adaade4402ffeb09f1a6d34a944c2f054d06d

* Removed log.quiet and log = NULL cases from debuggerd.Brigid Smith2014-06-196-81/+69
| | | | | | | | | Now the functionality implemented by these semi-confusing cases has been replaced with the same logtype enum behavior that is easier to understand, and cases that used log-looking behavior to print to logcat (when log = NULL) now use the more transparent ALOGE/ALOGD functions. Change-Id: I7e38f2d4ca74a828df4d2266b3ea34edd3c6f5bb
* Changed maps output in debuggerd.Brigid Smith2014-06-172-29/+13
| | | | | | | | | | | Now the map output is only sent to the tombstone, and the entire contents of /prod/$PID/maps is logged, not just 3 lines. Additionally, crasher now supports "crasher SIGSEGV-non-null", which attempts to write to a dereferenced function address, causing a SIGSEGV at a non-zero address. This new crasher mode can be used to test the new maps output. Bug: 15343662 Change-Id: I796d92e8352a6b9714bbbfe96f3143c56565ef2f
* Fixed logcat debug output issue.Brigid Smith2014-06-171-2/+4

* Changing how debuggerd filters log messages to different locations.Brigid Smith2014-06-1612-261/+263
| | | | | | | | | | | | | The system by which debuggerd filters its output to different locations is now based on an enum called logtype with easy to understand categories for log messages (like THREAD, MEMORY, etc.) instead of the old, fairly esoteric scope_flags variable. Now much of the output that previously went to logcat does not show up on the screen, but all output can be found in the tombstone file. In addition, the tombstone's location is now printed so it can be located easily. Bug: 15341747 Change-Id: Ia2f2051d1dfdea934d0e6ed220f24345e35ba6a2

* Use the si_code value bionic passes us.Elliott Hughes2014-04-254-40/+62
| | | | | | | | | Bionic needs to re-raise various signals, which means the si_code debuggerd sees has been clobbered. If bionic sends us the original si_code value, we can use that instead of the one we see when the ptrace the crashed process' siginfo. Change-Id: If116a6bc667d55a6fb39b74f96673292af4e4c8c

| | | | | | | | | | | | | | | | | Use the libbacktrace C++ interface instead of the C interface in debuggerd. Reformat the debuggerd code to be closer to Google C++ style. Fix all debuggerd casts to be C++ casts. Add a frame number to the frame data structure for ease of formatting and add another FormatFrameData function. Change the format_test to use the new FormatFrameData function. Modify all of the backtrace_test to use the C++ interface. Change-Id: I10e1610861acf7f4a3ad53276b74971cfbfda464

| | | | | | | | | This is part 1, only including the bare minimum changes because our diff tool doesn't easily show differences when a file moves.
