* Improve strace to log most Windows debug eventsJon TURNEY2015-06-111-2/+73
| | | | | | | | | | | | | | | | | | | | Not sure if this is wanted, but on a couple of occasions recently I have been presented with strace output which contains an exception at an address in an unknown module (i.e. not in the cygwin DLL or the main executable), so here is a patch which adds some more information, including DLL load addresses, to help interpret such straces. v2: Use NtQueryObject() for HANDLE -> filename conversion Add new '-e' option to toggle this additional logging 2015-06-07 Jon Turney <jon.turney@dronecode.org.uk> * strace.cc (proc_child): Log process and thread create and exit, and DLL load and unload.
