2018-05-30Fix warnings found by clang with new warning flags to be added in later commitEven Rouault
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
2018-05-24Handle double to int typecasts in ISEA betterKristian Evers
Originally the code was doing double to int conversions like y = (int)(x + 0.5) which results in rounding when typecasting. In an earlier attempt to avoid buffer overflows in integer typecasts this was changed to y = lround(x + 0.5) which doesn't give the origial results. We fix that here by instead doing y = lround(x) It is safe to so as long as x is positive.

As this is a part of PROJ, having these functions possibly not static is confusing. Time to declare this is just a part of PROJ.

2018-03-14PJ_isea.c: Remove unused structureEven Rouault
2018-03-11Remove angle brackets for proj headers (#849)Thomas Knudsen
* Avoid using angle brackets for PROJ headers. Switching from #include <proj.h> to #include "proj.h", and correspondingly for projects.h and proj_api.h, reduces the risk of accidentally picking up a system installed older version of the header while building a new version of PROJ. * Also handle geodesic.h
2018-01-09Remove or use unused macrosAaron Puchert
Some macros seemed to be leftover from earlier code, so I removed them. Others seemed like they should have been used, but weren't. There should be no functional change, except the following: in floating- point arithmetic, x / y is not the same as x * (1.0 / y). It can be argued that using the multiplication is significantly faster, and the algorithm is approximative anyway. Otherwise, the constants are obviously not required. Also fixes one location in PJ_aitoff.c, where an enumeration value should have been used.
2017-12-17Declare non-local variables as const where possibleAaron Puchert
Having non-const variables of static lifetime or even global scope is usually a bad idea. These variables are inherently constants, and this should be enforced. This required marking some functions as not modifying input parameters and marking some pointers as pointers to const. One advantage is that the compiler usually puts const static variables in a read-only code segment, so they can't be modified physically. This can be verified with `nm` (on POSIX systems). To avoid changes to the public API, functions returning non-const pointers to data tables were left intact, but the returned data may not be modified. Internally we prefer using the proj_list_* functions over the pj_get_*_ref functions, because the former return const pointers.

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
2017-07-18Expanded *_ERROR* macros.Kristian Evers
Expanded *_ERROR* macros with calls to proj_errno_set() and proper returns when necessary. Defined a bunch of new PJD_ERR_ constants in projects.h that corresponds to the error numbers in pj_strerrno.c. A few unknown error numbers were replaced by existing ones in pj_strerrno.c.
