* json.h: Add bytes and ubytes to json_array_t.Gary E. Miller2019-05-171-0/+6
| | | | No functional changes. Yet.
* json.h: add ubyte and byte to union addr and union dflt.Gary E. Miller2019-05-171-12/+16
| | | | No functional change, yet. Also sorted the entries.
* json.h: Add t_byte and t_ubyte to json_type.Gary E. Miller2019-05-171-2/+9
| | | | | | This is to allow the existing practice of using unsigned char fields in satellite_t and meas_t. Those existing uses are overflowing their fields.

* Address Savannah bug #46804: JSON satellite view parsing is somewhat broken.Fred Wright2016-01-041-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fred Wright <fhgwright> writes: While trying the regression tests on a MacBook (PowerPC), I ran across some failures in the JSON unit test. Although this is ostensibly an endian issue, it turns out that the code for parsing satellite view data is actually incorrect for all processors, albeit more so for big-endian processors. The problem is that the three "integer" fields in struct satellite_t are defined as shorts, but parsed as ints by the JSON parser. On a big-endian processor, this causes the values to be misaddressed and hence have incorrect values, but even on a little-endian processor this is incorrect since it's storing four-byte values into two-byte fields. The unit tests don't catch this aspect, since the fields are favorably ordered such that the clobbered fields are clobbered before being written pseudo-correctly. I was able to demonstrate the "buffer overflow" misbehavior by modifying the test data for the last satellite to provide the fields in the reverse order from their order in the structure. The simple fix for this would be just to change the shorts to ints in the definition of struct satellite_t. On most processors, this doesn't even cost any memory, since the presence of the double forces eight-bye alignment, so the padded structure is 24 bytes regardless of whether the three fields in question are shorts or ints. However, there might be some processors with less strict alignment requirements where using shorts would actually be helpful. With the existing layout, the only possible fix is to add support for shorts to the JSON parser, and adjust the satellite-view parsing accordingly. The attached patch does that, as well as adding u_short support for completeness (though it's not currently used). It also provides the aforementioned change in the test data, in keeping with the philosophy of "create a test for what just failed, so it doesn't happen again". Note that using shorts for these fields would be more effective if the "used" field were also reduced to a short, instead of inheriting "int" from "bool". That would shrink the structure to 16 bytes. It could be further reduced to 12 bytes by using a float instead of a double for the "ss" field (and even a float is gross overkill for this purpose). This could all be more significant when MAXCHANNELS needs to be increased (again) to accommodate the deployment of the newer GNSSes.

* Retire splint from our set of static analyzers.Eric S. Raymond2015-03-301-6/+4
| | | | | | | | | | | | | | | | | | | The proximate cause was that we've been seing emission of error messages that were randomly and disturbingly variable across different environments - notably Raspbian and Gentoo splint gave nontrivially different results than Ubuntu 14.10 splint. And this was *not* due to Ubuntu patches! A pristine splint built from the 3.1.2 tarball on Ubuntu didn't match the Raspbian and Gentoo results either. But this has been coming for a while. Easy access to more modern static analyzers such as coverity, scan-build and cppcheck has been decreasing the utility of splint, which is unmaintained and somewhat buggy and not easy to use. Only file not cleaned is ppsthread.c, because Gary has been working on it during this cleanup. All regression tests pass. PPS observed live on GR601-W.
* Hide a sys header from splintGary E. Miller2015-03-261-1/+3
| | | | gpsd.c is now splint clean on raspbian. YMMV
* Implement and test extended JSON array parsing.Eric S. Raymond2014-09-221-1/+13
| | | | | | Now supported: JSON arrays with int, unit, bool, and real elements. All regressiion tests pass.
* Typo fixes. All regression tests pass.Eric S. Raymond2014-09-171-1/+1
|
* The JSON parser now has an "ignore" type...Eric S. Raymond2013-10-011-1/+2
| | | | ...and it's used for the new dependent _text attributes.
* Nuke trailing whitespace in C source.Eric S. Raymond2012-09-071-8/+8
|
* json.h: Change JSON_VAL_MAX from 120 to 512Christian Gagneraud2012-06-201-1/+1
| | | | | | | This will allow the parsing long hexdump (data fields) in the AIS code. The longest JSON string I saw so far was 389 characters long. scons check passed.
* Get rid of nullbool default - not used, and it causes a bad smell to Coverity.Eric S. Raymond2012-05-111-2/+0
|
* Armor the JSON code against zeroed value or attribute pointers.Eric S. Raymond2012-05-101-0/+1
| | | | | Should never happen, but having the bailout logic in plavce creates static invariants that should banish a bunch of Coverity warnings.
* Cosmetic tweak: t_timestamp -> t_time.Eric S. Raymond2011-04-161-1/+1
|
* Add a 'timestamp' type to the JSON parser to solve a compatibility problem.Eric S. Raymond2011-04-151-0/+1
| | | | | | | Sigh, no other way to get DEVICELIST to recignize both new and old timestamps. All regression tests pass.
* Prevent JSON parsing from becoming confused by client locales other than C.Eric S. Raymond2010-12-171-0/+1
| | | | Fixes Berlios tracker bug #17379: problem with different locale.
* Internals of Qt support.Chris Browet2010-03-311-0/+6
| | | | | | | | | | | | | | | | | All regression tests pass. Note from esr: this feature cannot be announced yert, as it requires documentation in the INSTALL file. 1. What the target environments are (Linux? Windows? Both) 2. All build prerequisites (C++ compiler? Qt library? Other libraries?) 3. What the new files libQgpsmm_global.h and libQgpsmm.pro are for, and how the are used. We also need to know how to regression-test this code under Linux so we can verify that it's not broken as the client library evolves. Signed-off-by: Eric S. Raymond <esr@thyrsus.com>
