This change makes it all objects with a thin layer that C code can use. There is a C++ backtrace object that is not very useful, this code will replace it. This change also includes moving the backtrace test to a gtest, and adding coverage of all major functionality. Bug: 8410085 Change-Id: Iae0f1b09b3dd60395f71ed66010c1ea5cdd37841

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backtracing through eh_frame section is more effective allowing to reuse ebp register for other purposes within routine. GCC with turned on optimizations (-O1 and above) implicitly defines -fomit-frame-pointer anyway. eh_frame sections are generated by default with GCC on any optimization level. This change implements remote unwinding (separate process unwinding). Local unwinding is already implemented through _Unwind_Backtrace call which is implemented in libgcc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provides a new mechanism for dumpstate (while running as root) to request that debuggerd dump the stacks of native processes that we care about in bug reports. In this mode, the backtrace is formatted to look similar to a Dalvik backtrace. Moved the tombstone generating code into a separate file to make it easier to maintain. Fixed a bug where sometimes the stack traces would be incomplete because we were not waiting for each thread to stop after issuing PTRACE_ATTACH, only the main thread. So sometimes we were missing traces for some threads. Refactored the logging code to prevent accidentally writing data to logcat when explicitly dumping a tombstone or backtrace from the console. Only root or system server can request to dump backtraces but only root can dump tombstones. Bug: 6615693 Change-Id: Ib3edcc16f9f3a687e414e3f2d250d9500566123b

* Reduce suicidal tendenciesAndy McFadden2012-03-081-2/+12
| | | | | | | | | | | | | | | | | | Some changes to debuggerd: (1) Send a SIGSTOP to the target process before doing any of the PTRACE_ATTACH work. This causes the threads that weren't hit by the signal to stop moving, which seems to get rid of the "ptrace detach failed: No such process" problems that result in missed stack traces and debuggerd self-immolation. (2) SIGPIPE was in the list of "interesting" signals caught by debugger_signal_handler(), but debuggerd didn't recognize it, and you'd get "unexpected signal 13" complaints. It's now in the list. (3) Fixed a bit-rotted XLOG. Change-Id: I33297ea6b09ce450671c07dc25846f684afbf480
* Improve backtrace formatting.Jeff Brown2011-11-221-14/+19
| | | | | | | | | | | | | | | | | | | | Show the symbol offset, when available. Centralized formatting of native stack traces in libcorkscrew. It's handy for automated tools if all stacks look the same. Since we already made them all look them same, we might as well do the formatting in just one place. Do not strip the Thumb bit on ARM. This fixes an off-by-one issue that could happen when resolving a PC that was at the very beginning of a Thumb function, since the symbol table would have the Thumb bit set but since we stripped the bit from our PC, we would be looking for an address one byte before the one listed in the symbol table. It's also quite useful to see whether a given function is executing in Thumb mode just by glancing at the PC. Change-Id: Icaa29add85ce0bcafe24d5ce2098e138d809e2ab
