* Remove use of -rdynamic
This causes check-symbols to fail horribly and also turned out to be not
required when using libbacktrace. It was only required when using
"backtrace()" from "<execinfo.h>"
* Remove spurious ], from configure.ac
* Add -DENABLE_STACKTRACES=1 to CMakeLists.txt
* Remove unused method my_backtrace_simple_callback
* Use fs::path().filename() instead of basename()
* Add static g_exeFileName and g_exeFileBaseName
* Use .exe.dbg file when available
* Use uint64_t instead of uintptr_t
* Implement GetBaseAddress() for unix and win32
* Implement unified crash_info and use it everywhere before printing crash info
* Print a serialized version of crash_info when there is no debug info
* Implement "-printcrashinfo" command line option
* Compile stacktrace support unconditionally and only make crash hooks conditional
This also renames the --enable-stacktraces option to --enable-crash-hooks
* Enable crash hooks in win/linux Gitian builds
* Try to load .debug file on MacOS and enable crash hooks for osx Gitian builds
* Check for dsymutil and if it needs --flat
* Create .debug files in osx Gitian build
* Handle review comments
* Also print crash description when no stacktrace is available
* Unconditionally add -g1 debug information
Instead of making it dependent on "--enable-crash-hooks". We will need the
debug info every time now, even in release builds.
* Put MacOS debug info into dSYM symbols instead of plain .debug files
* Implement MacOS specific GetBaseAddress
* Add libbacktrace to depends
This is currently only useful to extract symbols. It fails to gather
stacktraces when compiled with MinGW, so we can only use it to get symbol
information from a stack trace which we gathered outside of libbacktrace.
* Add -mbig-obj to CXXFLAGS for MinGW builds
* Implement stacktraces for C++ exceptions
This is a hack and should only be used for debugging. It works by wrapping
the C++ ABI __wrap___cxa_allocate_exception. The wrapper records a backtrace
and stores it in a global map. Later the stacktrace can be retrieved with
GetExceptionStacktraceStr.
This commit also adds handlers to pretty print uncaught exceptions and
signals.
* Use GetPrettyExceptionStr for all unhandled exceptions
* Use --enable-stacktraces in CI for linux32/linux64
* Register exception translators to pretty print exceptions in unit tests
* Catch and print python exceptions when stopping nodes
Otherwise the code at the bottom is never executed when nodes crash,
leading to no output of debug.log files on Travis.
* Remove now unneeded/unused TestCrash methods
