Move lots of non-Serval-specific string functions from "serval.h"/dataformats.c
to "str.h"/str.c.
Add str_fromprint() function that reverses the effect of toprint(): interprets
escape sequences in the source string "\n\t\r\0\xHH\\" and replaces them with a
single char in the destination string.
Replace the main-loop scheduled periodic alarm with an "activate" alarm that is
scheduled whenever a fetch candidate is added to any queue, unless the alarm is
already scheduled.
Replace the "rhizome.fetch_interval_ms" config item with
"rhizome.fetch_delay_ms" [default 50], which is the number of milliseconds
between adding a fetch candidate and firing the "activate" alarm. This allows
time for a few more Rhizome advertisment packets to arrive after the first one,
before deciding which fetches to start first.
Add new `is_scheduled()` alarm primitive.
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.
Add test case for new feature of the "rhizome add" command: if the author SID
is not specified (empty arg) then it searches the keyring for the author.
Removed "authorSid" argument from several functions that also take a struct
rhizome_manifest * arg, since the author, if known, is now supplied in the
struct.
Improve return value handling and refactored some rhizome crypto code.
All test cases pass on Solaris (see issue #16) except the 'jni' tests because
there is no Java compiler available on Solaris, and the new 'rhizomeprotocol'
tests from the rhizomedirect branch, which have always failed.
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
serval_packetvisualise() is now replaced by DEBUG_packet_visualise() which uses
logging system not stderr (so now it will appear in Android log).
Replaced several fprintf(stderr,...) with DEBUGF(...).
Command line only prints a full help message on "help" command -- a command
parse failure simply informs the user about the "help" command.
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
Handle selection between normal & abstract sockets in a single place.
overlay_mdp.c tried to have both but this seems like a bug so I've removed the second socket (needs tests).
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".
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.
Was not transmitting actual HTTP server port in rhizome announcements, was
always transmitting port 4110.
When trying for a free HTTP server port, sometimes bind() succeeds but listen()
fails with EADDRINUSE, so new logic to deal with that.
Now write_str(), write_nonblock(), write_all(), set_nonblock() etc. report the
file/line/function of their caller, rather than the function in net.c. Done
using macros, similar in style to WHY() etc.
SET_NONBLOCKING(), SET_BLOCKING(), WRITE_STR() are now set_nonblock(),
set_block() and write_str() respectively, all of which log an error before
returning -1. There are other useful methods: write_all() treats anything less
than all bytes written as an error; write_nonblock() treats EAGAIN and EINTR as
zero bytes written, and a combination: write_all_nonblock().
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
... as part of working on work on DNA helper callout facility.
(DNA replies now contain a token that can be used to match them
against DNA requests as a happy side-effect).
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.
- Fix lsif() on OSX.
- Make lsif() smarter and avoid non-broadcast and no AF_INET addresses.
- Don't run multiple interface detectors, run one at a time until one works.
- Factor out HAVE_IFADDRS_H code into a separate function into lsif.c with the other interface detection routines.
- Prefer HAVE_IFADDRS_H (random bias..)
- /proc/net/route is Linux only.
- lsif() will work anywhere SIOCGIFCONF is defined.
- Abstract namespace UNIX domain sockets are Linux only.
- Rework code to reduce indent levels.
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.
Create datastore directory and all parent dirs if it does not exist
More robust error checking and buffer overflow protection
New mkdirs() and mkdirsn() functions
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.
Replace 'WHYRETNULL();' statements with 'return WHYNULL();'
Introduce DEBUG(), DEBUGF(), DEBUG_perror() and D macros
Add logMessage() and vlogMessage() functions
Implement setReason() using vlogMessage()
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
