Refactor much of the new code in log.c
Add new functions: cf_load_strict() and cf_reload_strict() for use by the
server, which does not want to overwrite its in-memory config at all if there
is any defect in the config file. However, commands always want to overwrite
the default in-memory config, even with a defective config file, so that
logging has a chance to succeed.
Added `log_format.dump_config` boolean config option
OUT()s or where return() is used instead of RETURN().
Added OUT() to end of all functions using IN() that lacked it to
make it easier to statically analyse this invariant.
Fixed several return instead of RETURNs detected through use of
this tool. #49
- made some debug output conditional.
- make it possible to debug slip decoding without getting swamped by other output.
- Improve reporting of unnamed schedule() calls.
- always collect performance statistics, and report on any excess
use (>1sec in every 3), even if debug.timing is not enabled.
- include file size information in Rhizome transfer messages.
- reduce output when debug.rhizome_rx is set.
Replace explicit [<pin,pin...>] command-line arguments with --entry-pin=<pin>
options. Update test scripts accordlingly.
Add --keyring-pin=<pin> option (with one test case).
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.
