* Fatal typo broke the build. Oops.Eric S. Raymond2016-01-171-1/+1
|
* Simpler fix for fd clobbering in the SHM library interface.Eric S. Raymond2016-01-171-3/+7
|
* Prevent gps fd from being stimpeed by shated-memory interface.Eric S. Raymond2016-01-161-1/+2
| | | | Fix due to Simon Hradecky <shradecky@nomissoft.com>.
* Fix memory leak in case of shmat() failureZbigniew Chyla2015-06-011-0/+1
|
* Fix checking the result of shmat() callZbigniew Chyla2015-06-011-1/+1
| | | | The code was checking "privdata" pointer instead of shmat() result.
* Revert "Copy structs using assignment, not memcpy()."Gary E. Miller2015-04-281-2/+6
| | | | | | | | | | | | | | | | | | | | This reverts commit d1965788249d7e22cdde4021d452cf0dc6c6b9bd. This breaks my build on Gentoo running gcc 4.9.2 libgps_shm.c: In function 'int gps_shm_read(gps_data_t*)': libgps_shm.c:122:12: error: no match for 'operator=' (operand types are 'gps_data_t' and 'volatile gps_data_t') noclobber = shared->gpsdata; ^ libgps_shm.c:122:12: note: candidate is: In file included from gpsd.h:350:0, from libgps_shm.c:30: gps.h:1918:8: note: gps_data_t& gps_data_t::operator=(const gps_data_t&) struct gps_data_t { ^ gps.h:1918:8: note: no known conversion for argument 1 from 'volatile gps_data_t' to 'const gps_data_t&'

* Retire splint from our set of static analyzers.Eric S. Raymond2015-03-301-8/+2
| | | | | | | | | | | | | | | | | | | 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.
* Clean up most spint errors. All regression tests pass.Eric S. Raymond2015-03-281-1/+1

* Yet more: Line expects to suppress X error, found 0 errorsGary E. Miller2015-03-251-1/+1
|
* remove extraneous semicolonGary E. Miller2015-03-131-1/+1
|
* splint/cppcheck/coverity prerelease cleanup.Eric S. Raymond2015-03-131-1/+1

* Document SHM and JSON timeout is in uSec. Fix SHM so that is true.Gary E. Miller2015-03-121-2/+3
| | | | | JSON wait was in uSec, but SHM wait was in Sec. Made both uSec and documented three places.
* OS X needs a lot of time.hGary E. Miller2015-03-081-0/+1
| | | | | | gpsd_config.h needs time_t which is in time.h OS X builds now. Untested.
* Insert memory barriers in libgps_shm_waiting().Eric S. Raymond2015-03-061-4/+8
| | | | | | Also, make sure it reurns false on timeout. All regression tests pass.
* Comment and documentation polishing.Eric S. Raymond2015-03-061-1/+1
|
* Repair the logic for setting a non-default SHM export segment.Eric S. Raymond2015-02-161-1/+1
| | | | | | Also, ensure this always happens within the regression-test driver. All regression tests pass.
* Instrument shm segment creation a bit better.Eric S. Raymond2015-02-111-2/+4
| | | | All regression tests pass.

|
* First part of Android port patches: deal with in_port_t. SUN_LEN, and getsid().Eric S. Raymond2014-08-181-2/+4
| | | | | | | | | Also, fix how configuratuin in libgps_shm.c and smexport.h is handled. Based on a patch by Samuel Cuella <samuel.cuella@supinfo.com>, but cleaned up some to obey local conventions better. All regression tests pass.
* Clarifying name change. All regression test pass. PPS is live.Eric S. Raymond2013-11-061-7/+7

|
* Part repair of the shm dispatch.Eric S. Raymond2011-03-271-0/+1
| | | | | Uh oh. One of my rests was broken. The gps_shm_* functions work, but dispatch to them through the public API is broken. This partway fixes it.
* Shared-memory export is now integrated and documented.Eric S. Raymond2011-03-271-0/+2
|
