Introduce __WHENCE__ macro and a block comment in log.h explaining it.
In "primitive" kinds of functions, rename 'whence' arguments to '__whence' and
use WHYF(), WARNF(), DEBUGF() macros instead of calling logMessage() directly.
Replace "..." quoting with `...` quoting in output, to avoid slosh-escaping the
common double-quote character (") in log output.
Introduce alloca_str_toprint() function that produces an entire null-terminated
string in printable form.
Change various toprint strbuf helper functions to take two optional quote chars
instead of one mandatory.
Replaces (const char *file, unsigned int line, const char *function) arguments
to all logging functions, simplifies malloc/free tracking code in
overlay_buffer.c and Rhizome manifest alloc/free tracking in rhizome_bundle.c.
Use __HERE__ macro instead of (__FILE__, __LINE__, __FUNCTION__) everywhere.
Special __NOWHERE__ macro is equivalent to (NULL, 0, NULL).
Declare net.c functions in new "net.h" header, so log.c doesn't have to pull
in the entire "serval.h" just to use write_str().
Facilitates progress on issue #2.
Replace DEBUG_SIMULATION with DEBUG_VOMP
Replace all printf(...) and fprintf(stderr,...) with WHYF(...) and DEBUGF(...)
Make all debug logging conditional on DEBUG_VOMP
Move DEBUG_ and LOG_LEVEL_ macro constants from constants.h into log.h.
Move dumpResponses() out of log.c, so that log.h is almost ready for re-use
(still depends on conf.h).
Remove unused and now obsolete catv() function -- replaced with toprint()
and alloca_toprint().
Add copyright/licence comments, fix up some copyright attributions.
Add #ifndef..#define..#endif __SERVALD_FOO_H to header files: log.h serval.h
constants.h
Servald starts DNA helper, receives startup ACK, sends requests, receives
responses, handles malformed helper responses, echoes dnahelper stderr lines to
log, sends MDP reply packet, waits for dead helper process, all asynchronously.
Shuts down helper process during servald shutdown.
Remaining issues:
- Does not impose a timeout on helper responses.
- Only the first URI is reported by the "dna lookup" command.
Fix endless recursion if error or debug logged while reading config file
Fix 'config del' logic
Log messages made before log file can be opened are buffered and written
once the file is open
Do not log to file in ANDROID version, just to Android's log system
