* Back out the attempt to use VTIME.Eric S. Raymond2015-01-311-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to Matthias Drochner at http://lists.lysator.liu.se/pipermail/lsh-bugs/2003q4/000151.html: I thought I'd give lsh a try, just to see how it compares to openssh... The client didn't work well on NetBSD, got a message like "unexpected EWOULDBLOCK" on each keystroke. Looked a bit deeper and found that stdin is set to O_NONBLOCK and a raw tty mode with c_cc[VMIN] > 1 and c_cc[VTIME] > 0. I'll append a little test program which does the same. I've tried it on 3 operating systems (Linux, NetBSD, Digital UNIX), and it behaves differently on each: -on Linux, if a key is pressed, the read returns immediately with that one character -on NetBSD, the read returns with no data but EWOULDBLOCK -on D'UNIX, the poll() doesn't teturn before 4 keypresses are done; the read() returns these 4 characters Indeed, in SUSv2's termios page is a sentence which says that if both O_NONBLOCK and VTIME>0 are set, the behaviour is more or less undefined. I've solved my immediate problems by setting VMIN to 1 instead of 4 in unix_interact.c:do_make_raw(), but VTIME is still pointless, so I wouldn't call this a clean solution. All regression tests pass.
* Add a minimum packet length to every driver.Eric S. Raymond2015-01-291-0/+1
| | | | Length 0 means the minimum is unknown and the driver should use character I/O.
* Fully initialized fields in some time structures.Eric S. Raymond2015-01-231-2/+5
| | | | This fixes an hour-offset bug due to the tm_isdst member being uninitialized.
* cppcheck cleanup.Eric S. Raymond2015-01-221-2/+1
|
* Coverity/splint cleanup.Eric S. Raymond2015-01-211-0/+6
| | | | | Turned up a bug in where a counter was incremented un the Navcom driver; this required one test rebuild.
* Easy splint cleanups. All regression tests pass.Eric S. Raymond2015-01-211-6/+7
|
* Add str_{,v}appendf, use it everywhere.Zbigniew Chyla2015-01-211-7/+4
| | | | This change doesn't affect generated binary code.
* Almost entirely eliminate use of sats_used array.Eric S. Raymond2015-01-101-5/+1
| | | | | | | Instead, set the used member in the satellites array directly where possible. The NMEA0183 and TSIP drivers still need a local equivalent. This changes pseudo-NMEA GSA output in several binary-protocol tests.
* Revise SiRF driver to be get satellites-used info from the skyview sentence.Eric S. Raymond2015-01-091-18/+25
| | | | | | | | | | | Before, that information was partly coming from the navigation-solution message and being pieced together with related data from svinfo. This way of doing things is more consistent. While this change required a rebuild of four check files, the effects are minor. Fixes don't change, but some generated pseudo-NMEA does and the error modeler can sometimes compute error estimates in cases where the old code could not because of a determinant-zero condition.
* Tweak to ifdef guard for RECONFIGURE_ENABLE in driver_sirfJon Schlueter2015-01-091-1/+1
| | | | | | | Warning cleanup that one of the nav message was not used if RECONFIGURE_ENABLE was not defined. Inspection shows that it is only used from within code guarded by the same ifdef guard so adjusted to clear the compile warning.
* Better way to avoid glibc dependency.Eric S. Raymond2014-09-291-3/+3
| | | | | | | Returns us to something amost identical to the original code. Sigh. Timezones are a swamp. All regression tests pass.
* Remove some custom code, at the cost of introducing a glibc depenency.Eric S. Raymond2014-09-251-2/+2
| | | | Dependency soon to be fixed. All regression tests pass.
* Refactor representation of satellite data into an array of structs...Eric S. Raymond2014-09-221-11/+16
| | | | | | | | | | | | | | | | | | ...from a set of parallel arrays. This change flushed out a longstanding bug in the computation of DOPs for estimated error bars. Some test-load rebuilds were required: geostar-geos1m-binary.log.chk: With this change error estimates are computed and reported. trimble-lassen_iq-3dfix.log, trimble-lassen_iq-3dfix.log: the change revealed a bug in the computation of satellite-seen bits. Error estimates did not change. navcom.log: Error estimates changed. With these rebuilds, all regression tests pass.
* Add some warnings about SiRF-IV flakiness, and remove a related TO-DO item.Eric S. Raymond2014-08-291-0/+7
|
* Now that the transition is done we can restore the gpsd_report name.Eric S. Raymond2014-08-271-89/+89
| | | | All regression tests pass.
* The big leap. Most instances of gpsd_report are replaced...Eric S. Raymond2014-08-271-89/+89
| | | | | | | | | | | | | | | | ...with calls to gps_notify(), which indirects to its output method through a slot in an errout structure. Usually the errout structure lives inside the session context, but because struct errout_t is its own thing this does not have to be the case. One large clique of gpsd_notify() calls, in packet.c and isgps.c, looks at a struct errout_t copy in a lexer control block This change is not complete. Remnant gpsd_report calls need to be changed, and gpsmon needs to be tweaked so that the struct_error_t in its context is a non-defaukt hook updating the cuses display rather than simply dumping to stderr. Also the report label functionality needs to be added. All regression tests pass.
* Introduce struct errout_t to encapsulate error-reporting hooks.Eric S. Raymond2014-08-271-89/+89
| | | | | | A major step towards eliminating reverse linkage. All regression tests pass.
* Structure member name change: packet -> lexer. No logic changes.Eric S. Raymond2014-08-271-6/+6
| | | | All regression tests pass.
* Another step away from reverse linkage. No logic changes.Eric S. Raymond2014-08-271-46/+51
| | | | All regression tests pass.
* Satisfy an order dependency in SiRF initialization.Eric S. Raymond2014-08-271-17/+20
| | | | Follows a tip from Michael Tatarinov.
* Split firmwqre version query out of the init method.Eric S. Raymond2014-08-251-10/+12
| | | | | | This enables us to force readonly off while it's being called. The practical effect is that gpsmon can get a firmware version (if this is possible) without reconfiguring the device.
* splint/ccpcheck cleanup.Eric S. Raymond2014-08-241-4/+4
|
* Eliminate the tag field entirely, even internally.Eric S. Raymond2014-08-241-6/+5
| | | | All regression tests pass.
* Drop the obsolete tag field from JSON output. Bump the minor protocol number.Eric S. Raymond2014-08-241-6/+5
| | | | | | | Required a regression-test rebuild, of course. The field is still set by the TSIP and SiRF drivers; the SiRF driver actually uses it. It may be possible to eliminate the TSIP uses, but so far attempting this has produced odd regression-test failures.
* Document sSiRF sentence suppressions better.Eric S. Raymond2014-08-211-15/+17
|
* Revert "Remove dodgy sentence-suppresion code in SiRF driver."Eric S. Raymond2014-08-211-0/+6
| | | | Dodgy code turned out to be right after all - just needs documentation.
* Remove dodgy sentence-suppresion code in SiRF driver.Eric S. Raymond2014-08-211-6/+0
| | | | All regression tests pass.
* Turn off GND in SiRF binary mode, as we don't use it.Eric S. Raymond2014-08-201-9/+14
| | | | | | This is in response to a report by Jeff WEoolsey on gpsd-dev indicating that it masy be *required* to turn this off to get accurate time...
* Revert "Constify some storage. All regressions tests pass."Eric S. Raymond2014-08-201-16/+16
| | | | It failed on a live GPS, in the configuration code.
* Constify some storage. All regressions tests pass.Eric S. Raymond2014-08-191-16/+16
|
* Refactor initialization, and again disable wait on ACK.Eric S. Raymond2014-05-191-14/+23
| | | | | With this code, direct-mode gpsmon speed changes work on SiRF II, III, and IV. Direct-mode gpsctl speed changes work on SiRF II and III, fail on SiRF IV.
* Instrument so we can tell when a SiRF control is sent out with ACK pending.Eric S. Raymond2014-05-181-1/+23
|
* Back out my attempt at ACK synchrinization, it fails on SiRF III.Eric S. Raymond2014-05-181-27/+0
|
* Cut down on the sentence mix transmitted from the device.Eric S. Raymond2014-05-181-2/+11
| | | | | | | From a patch by Michael Tatarinov. Does no harm, and may be required for SiRF IV to work. All regressiion tests pass.
* Add timeout on wait-for-ACK to SiRF driver.Eric S. Raymond2013-11-191-5/+18
| | | | Correct initialization observed oon SiRF-III. All regression tests pass.
* Document the SiRF IV issue.Eric S. Raymond2013-11-181-1/+6
|
* Add a warning when a SiRF message send fails.Eric S. Raymond2013-11-181-2/+5
|
* We attempt to count ACKs to avoid pproblems on the SiRF IV.Eric S. Raymond2013-11-181-16/+7
|
* spint annotation fixes. No logic changes.Eric S. Raymond2013-11-181-1/+1
| | | | All regression tests pass, PPS is live.
* Stall SiRF writes the minimum necessary to guarantee a 4-second cooldown.Eric S. Raymond2013-11-181-43/+86
| | | | | Works on a BU-355 (SiRF-III); at least, it gets through the configuration sends with little stalling.
* SiRF now recommends at least 57600 to use nav data.Gary E. Miller2013-11-151-2/+4
|
* More consistent use of SiRF settling time.Gary E. Miller2013-11-151-10/+1
|
* Document en-/dis-able SiRF subframe. remove redundancies.Gary E. Miller2013-11-151-27/+11
|
* Disable MID 64 in SiRF as it floods the stream at 4800Gary E. Miller2013-11-151-0/+6
|
* Collect all the SiRF settling time constants into one define.Gary E. Miller2013-11-151-15/+18
| | | | | Also make it a lot longer than before. The SiRF driver should also be listening for the ACK/NACKs.
* More consistent ise of LOG_PROG.Eric S. Raymond2013-11-121-2/+2
| | | | This logging level is intended to directly explain accompanying I/O messages.
* Reduce gpsd log verbosity a lot.Eric S. Raymond2013-11-121-2/+2
| | | | | | | | | | Way too much logging was happening at LOG_IO level, which is intended for watching data traffic in and out of the daemon rather than all the minutiae of data analysis - that's LOG_DATA. Also, LOG_DATA gets pushed down two levels. The effect is that -D 5 means exactly what it did, but for purposes other than driver debugging -D 4 now suffices.
* Rename and rationalize driver table instances. No logic changes.Eric S. Raymond2013-11-121-2/+2
|
* A bit more SiRF IV decoding.Gary E. Miller2013-11-121-14/+94
|
* Start to decode new SiRF IV messages.Gary E. Miller2013-11-111-3/+34
