Fixes consist in: - no use of comma operator for multi statement purpose - avoid confusing comma in for loops first and third clauses - avoid implicit long to int casts by storing to long, or explicit bound checking before cast

2018-04-25pj_transform: reset error state before each call to pj_inv/pj_fwdEven Rouault
Fixes issues raised in https://lists.osgeo.org/pipermail/gdal-dev/2018-April/048446.html The use case is that pj_transform() is called from geos projection to something else, with multiple coordinates. If one of the coordinate tuple fails the inverse transform of geos, it fails with PJD_ERR_TOLERANCE_CONDITION. Causing all following coordinates to fail since the error state is not reset.
2018-03-11Remove 'pj_' prefix from static functionsKristian Evers
Functions should only be prefixed with 'pj_' when they can be used in other parts of the code base and not just within a single file. Takes care of the last step in #675.

2018-03-01Revert fix to #22Kristian Evers
The fix in #22 solved the problem at hand and doing what was expected from the specified parameters. Unfortunately it also removed the slightly hacky "feature" that makes the web mercator work in pj_transform. The web mercator is special since the latitude is computed on the ellipsoid, but behaves as if if was defined on a sphere. Hence it is problematic to change the ellipsoid parameters when using the web mercator, even though that is the geodetically correct thing to do. The web mercator is used in more or less any web mapping application and is thus one of the most frequently used transformations in PROJ. This justifies re-introducing the minor bug reported in #22. The problem will have to be taken care of properly when pj_transform is removed from the library in favour of the transformation pipelines based API.

2018-01-23Handle ellipsoid parameters correctly when using +nadgrids=@null. Fixes #22.Kristian Evers
Make sure to not change ellipsoid parameters to WGS84 when applying the null grid. Coordinates will still refer to the input ellipsoid so we keep the original parameters which in turn will be used when the coordinates are transformated to/from cartesian/geocentric space. Adjusted regression test material in nad/proj_outIGNF.dist slightly to accomodate numerical differences at the mm level. The transformations in question are at best accurate to about 1m so this shouldn't change real world usage of these transformations.

2017-10-06Enable default destructor for all PJ objects.Thomas Knudsen
In most cases memory deallocation is completely removed from the code since it can be handled by the default destructor. In a few special cases a local destructor overrides the default destructor and makes sure that locally allocated memored is cleaned up correctly. Move all deallocation from pj_free to pj_default_destructor Rename pj_latlong.c to fit with the conventional format PJ_latlong.c - freeup was missed here due to wrong naming Clean up pj_init to avoid double deallocation; Also resolve #576 by adding z_0 and t_0 options in pj_init, while cleaning Add a prototype for dealloc_params Added missing errno.h include in pj_ctx.c Temporarily removing ob_tran from testvarious, to be sure that is where the trouble is Make PJ_ob_tran.c use proper initialization for the chained projection proj=ob_tran: make it clear, that we disallow ellipsoidal projections, and, for improved backwards compatibility, turns off default settings, which could inject unwanted ellipsoid definitions ... then also remove the ellipsoid definition from the testvarious test case - which is probably buggy anyway Work around cs2cs spherical init bug in testvarious; Forbid defs for ob_tran in pj_init

facto standard M_PI and its ilk. Change names that are widely used in the project to be in the M_ namespace, so HALFPI becomes M_HALFPI.
