Nick Mathewson	bd8ad674b9	Add a sighandler-safe logging mechanism ... We had accidentially grown two fake ones: one for backtrace.c, and one for sandbox.c. Let's do this properly instead. Now, when we configure logs, we keep track of fds that should get told about bad stuff happening from signal handlers. There's another entry point for these that avoids using non-signal-handler-safe functions.	2013-11-18 10:43:15 -05:00
Nick Mathewson	063bea58bc	Basic backtrace ability ... On platforms with the backtrace/backtrace_symbols_fd interface, Tor can now dump stack traces on assertion failure. By default, I log them to DataDir/stack_dump and to stderr.	2013-11-18 10:43:14 -05:00
