Use sigaction(2) instead of deprecated signal(2), allowing SEGV et al to be
received in handler and therefore in re-spawned server.
Receive SIGSEGV et al in a separate handler function which kills the server
with the same signal if it does not re-spawn.
Log a GDB backtrace on SEGV et al before exiting or respawning.
Rename config option "serval.respawn_on_signal" to "server.respawn_on_crash".
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()
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
This requires building with _GNU_SOURCE to get access to struct ucred on Linux. Previously the test failed on every platform except glibc <2.8 or so.
Building with _GNU_SOURCE causes TRUE to be defined so we can't use this as a variable anymore, and MIN/MAX so don't define our own.
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.
The sequence start time was only getting set in overlay_interface_init(), which
was not always called, or was called after overlay_gettime_ms() had already
been used.
Added FATALF(), FATAL() and FATAL_perror() macros.
Removed a bunch of debug statements no longer needed in monitor.c and server.c.
Rename pidfile 'serval.pid' to 'servald.pid'
Rename stopfile 'doshutdown' to 'servald.stop'
Reinstate checking of stopfile on signals and in main loops
Correct delay loops in 'start' and 'stop' commands
Move some code from commandline.c to server.c
Now correctly probes for server process existence using kill(pid, 0)
Status command does not dump config (use "config get" instead)
Output uses JNI cli output fields
Stop command uses 5 Hz wakeup, not busy wait while server exits
General improvements to handling identities from keyrings.
Fixed placing of DONE flag for each identity that a query
produces results as.
Various other fixes.
- refactor hlrSid() to not return pointer to static buffer, take 3rd arg instead
- introduce SID_STRLEN macro constant, use it everywhere
- reformat some code for readability
