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
