| * | I don't think a singular LOS matrix is worth a LOG_WARN. | Chris Kuethe | 2009-07-07 | 1 | -33/+35 |
| | | | | | | Also, report which device is feeding the data that causes this singular matrix. And some whitespace cleanups while I'm here... | ||||

| | | | | | | | | | | | | | | | | | | | | | | | 1). I think the description of the co-variance matrix is wrong. I expanded the squared terms so that s(n)^2 became s(n)*s(n) and so on. I then swapped the first and second parts of some terms so that the columns formed a regular pattern. I then "fixed" the terms which seemed wrong and simplifed the s(n)*s(n) terms back to s(n)^2. This does not affect the code, which implemented the correct matrix anyway. 2) The reporting of DOPS had the text descrtiption of calculated and reported fields reversed. 3) The reporting of DOPS had a duplicated pair of format fields for the TDOP. The format now matches the data. | ||||

| * | Fix to time conversion by Petr Slansky; passes all stable regressions. | Eric S. Raymond | 2007-12-11 | 1 | -7/+6 |
| | | | | | Also, change a formal from int to size_t appropriately. | ||||
| * | One bit of the algebra in the DOP computation from satellites was incorrect; | Eric S. Raymond | 2007-12-10 | 1 | -9/+40 |
| | | | | | | | | it affects computed VDOPs. Also, never override a reported DOP component with a computed one -- GPS firmware sometimes does satellite deweighting in useful but tricky ways, and we don't want to lose this advantage. | ||||
| * | avoid a core dump if somehow one of these pointers is NULL | Chris Kuethe | 2007-10-16 | 1 | -0/+2 |

| * | Our formula for computing estimated track error was computationally unstable. | Eric S. Raymond | 2006-12-08 | 1 | -6/+6 |
| | | | | | | | | | | | | | | | | At low velocities it often yielded NaN on a 64-bit machine but a number close to 180 degress on a 32-bit machine. Address this by (a) punting to NaN when points very close together cause rounding-error blowup in the earth_distance() formula, and (b) punting to NaN when distance between fixes is less than the horizontal fix error estimate. The effect is that estimated track error will be NaN more often, but otherwise much more reliable and less prone to diverge between systems with different word sizes and/or FPU hardware. This change cuts the observed number of diff lines generated by 'make regress' on a 32-bit machine roughly in half. | ||||
| * | Convert some log levels I missed first time around. | Eric S. Raymond | 2006-11-02 | 1 | -1/+1 |

| * | Define uniform log level macros. | Eric S. Raymond | 2006-11-02 | 1 | -9/+9 |
| | | | | | | | | | | | | | | | | | | | | | | | This patch defines a uniform set of log levels and changes all gpsd_report() instances to use them. In most cases (I'd say about 80%) this will make no observable difference, as the numeric log levels the code was using were not too badly inconsistent anyway. The new log level macros are defined and described in gpsd.h. The main thing I wanted was to be able to consistently force dumping of all I/O to devices and clients with -D 4. Some drivers didn't honor this. One or two still may not through lack of an internal write() wrapper that does logging; there will need to be some followup changes. Level 0 messages are always displayed, but to make the semantics clearer there are two defines LOG_ERR and LOG_SHOUT. Level 5 is still super-raw I/O reporting. Level 6 and 7 messages are tagged RAW_LOG+1 and RAW_LOG+2; I was particularly careful about these because we have one report of a user who is getting good results from Garmin serial only at -D 7 or up, and perish forbid I should interfere with that bug being found. | ||||
| * | Rename config.h so it can be installed as gpsd_config.h... | Chris Kuethe | 2006-10-26 | 1 | -0/+2 |
| | | | | | | | ...for those who want to build their own apps linked against libgps and want the headers to work. Works on OpenBSD, tested by Jeff Francis on OS X and Linux | ||||

| * | Design decision: Trie North data gets mapped into existing fields (track, etc) | Eric S. Raymond | 2006-08-31 | 1 | -6/+0 |
| | | | | | | | | | ...rather than new ones like heading. This gets rid of the HEADING_FIX code contributed but not compiled in by default. Also, fix a place in the zodiac driver that sets a fix rather than newdata member. | ||||
| * | Properly clear out latitude and longitude. | Eric S. Raymond | 2006-08-21 | 1 | -0/+1 |

| * | String safety, courtesy of snprintf, strlcat and strlcpy. | Chris Kuethe | 2006-08-19 | 1 | -1/+1 |
| | | | | | | | | GPSD is now free from the often-misused strcat, strcpy and sprintf. Future code should not use unbounded string functions. Glibc users, please verify that the integrated strlcat and strlcpy are correctly linked in. | ||||

| * | True North support integrated. | Eric S. Raymond | 2005-08-01 | 1 | -1/+1 |
| | | | | | | | It's not compiled in by default, but it does require one architecture change -- device channels is now a driver- specific capability, since the Thales GPS our TrueNorth user is working with has 14 channels. | ||||
