Oliver Jowett 849697f84c Fix integer overflow in stats output. 2015-02-11 00:14:28 +00:00
Oliver Jowett f9ed7e4a97 More time_t -> milliseconds conversions.
This lets us support fractional net flush times among other things, which is handy.

Oliver Jowett 7053ad02da Make aircraft tracking use milliseconds everywhere. 2015-02-10 21:49:37 +00:00
Oliver Jowett a49b5b8830 Add stats for total aircraft tracks and tracks that have only a single message. 2015-02-08 18:47:39 +00:00
Oliver Jowett 4e177c2d64 Store computed reception time in the message struct so we don't rely on
the message being emitted immediately.

Fix computation of reception time so it's more sensible (the block timestamp
is some time after reception of the _end_ of the block, not the start) - this
means that message-emission times are always later than message-reception
times in SBS output, which is a bit more sensible.

Use clock_gettime in preference to ftime.

Oliver Jowett 20407e5378 Don't emit SBS output with non-ICAO addresses (fixes #9) 2015-02-08 14:30:10 +00:00
Oliver Jowett 245bbd8b97 Report total, not latest-minute, message count in aircraft.json so that
the webmap value doesn't jump around over a reset.

Oliver Jowett c5b61a33fd Oops, another compile error, sigh. 2015-01-23 02:11:44 +00:00
Oliver Jowett c07e45a4c8 Report CPU in integer milliseconds, makes it a bit easier to process. 2015-01-23 02:03:57 +00:00
Oliver Jowett 5b40377b98 Measure CPU for demodulator, read thread, and background tasks individually. 2015-01-23 01:22:22 +00:00
Oliver Jowett eb023ff1d9 Don't include latest in 1/5/15 min totals, it's a bit confusing.
This means the 1/5/15 min values may reflect a period that ended
up to 1 minute ago, but the length of the measured period is always
as expected i.e. 1/5/15 mins.

Oliver Jowett c8025700e5 Emit all stats in stats.json. 2015-01-22 20:18:51 +00:00
Oliver Jowett 008ae926e7 Add --net-verbatim, which forwards the original uncorrected message to net clients,
not the corrected version. Then the client can make its own policy decisions about
whether to accept and correct the damaged messages.

Oliver Jowett a59077a370 Stats overhaul. 2015-01-22 19:49:19 +00:00
Oliver Jowett b77d52bd1f Include recent RSSI in aircraft output. 2015-01-22 15:30:34 +00:00
Oliver Jowett 89d6b64747 Treat signal level in network messages as a (RMS) amplitude, since that
is what was previously done and it gives us better range for small signals.

Means a sqrt() call on beast output, but this shouldn't be too bad as
it's only done once per message.

Oliver Jowett 35e0364670 Fix compile errors. 2015-01-22 13:29:13 +00:00
Oliver Jowett 70e8579850 Simple filter for spurious messages that make it past checksum:
don't show aircraft until we have seen 2 messages from them.
2015-01-22 13:22:16 +00:00
Oliver Jowett ada188a1c8 Changed my mind, put the non-ICAO flag bit in the address itself
since we have 8 bits spare, so there's no chance of confusing it
with an ICAO address, and we can safely use the filter table to match
future messages without also matching equivalent ICAO addresses.

Oliver Jowett 35551b4455 Don't emit FATSV output for non-ICAO addresses. 2015-01-22 12:18:46 +00:00

Oliver Jowett 7850848ef7 Export a few stats via JSON. 2015-01-22 01:21:53 +00:00
Oliver Jowett 19082d92ea Measure signal power / noise power (at least in 2.4MHz mode).
Switch signalLevel back to a power measurement, don't put SNR in there.
But make it a 0.0 - 1.0 double so we're not scaling everywhere.

Adjust for the amplitude offset when calculating power.

Adapt everything else to the new scheme.

Oliver Jowett c712543ee5 Only completeWrite() if we didn't run off the end of the buffer.
If we did run off the end, complain about it.

Oliver Jowett 39d905324f Be more paranoid about not overrunning our fatsv output buffer.
Request a buffer of a more reasonable size.
2014-12-08 20:14:53 +00:00
Oliver Jowett 2dcc8e3524 Add direct support for FATSV-format output.
This is adapted from the FlightAware fork, with some cleanup and
modifications needed to work with the net-cleanup changes.

Inclusion of "verbatim" TSV data read from an AVR-format input
connection is not supported.

Oliver Jowett af957da81c Merge branch 'realpath-memory-leak' 2014-12-07 14:10:17 +00:00
Oliver Jowett d09eefb827 Fix a memory leak from use of realpath() in HTTP request processing.
realpath() returns a heap-allocated buffer if given NULL for the destination buffer.
This must be freed by the caller; dump1090 does not do this.

Instead of worrying about freeing it, take the simpler approach of just providing a
stack-allocated destination buffer.
