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
Use ssize_t and size_t where required by system calls
More stringent checking of errors from system calls
Log the offset when writing to dummy interface file
Clean up many WHY/INFO/DEBUG statements
Convert many fprintf(stderr,...) to DEBUGF()
Debug bit mask is unsigned int everywhere.
Refactor DEBUG() macros a bit.
Add SERVALD_DEBUG_FILE env var to support test scripts.
Test defs put instance directories under $TFWVAR not $TFWTMP.
Replace with WHY() or WHYF() everywhere
Improve logMessage() to handle file/line/function printing internally
Mainly so that log messages from manifest alloc/free in rhizome_bundle.c
can make it into the Android log
Config debug flags are now represented as individual items, eg:
servald config set debug.verbose yes
servald config set debug.rhizome yes
instead of aggregated, eg:
servald config set debug verbose,rhizome <-- no longer works
Added a debug flag "debug.all" that can be set and cleared, over which
individual flag sets/clears take priority.
Slimmed down dna.c by moving some globals and functions to the files where they
are used.
Default command line (help message) is now the new style, not the deprecated
style.
