2018-04-16Collect custom C99 math functions in proj_math.hKristian Evers
We are relying more and more on C99 math functions. On C89 systems where those functions are not available our own custom versions of those functions are used instead. So far these has been spread across the code base. This commit gathers them in the same file and introduces the proj_math.h header. The build system checks for C99 math functions. If not found the proj_math.h header make sure that C99 functions are defined as their pj_ equivalent. Ideally proj_math.h is included instead of math.h. This removes the need for any checks against HAVE_C99_MATH in the code making it easier to read. For this commit the functions hypot, log1p and asinh has been taken care of.
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.
2017-11-13Removed remaining traces of the built in selftest system (#661)Thomas Knudsen
* Removed remaining traces of the builtin selftest system. Moved all functionality to test/gie * Updated Appveyor and Travis build scripts * Another appveyor script update

2017-11-06Use enumerations where appropriateAaron Puchert
Enumerations have the following advantages over #define: - they clearly connect a variable and the allowed constants, - the meaning of code is not obfuscated by integer values, - they are visible to the compiler, which can warn about (possibly) incorrect usage. There should be no functional change.
2017-10-19Prevent crashes and leaks on allocation failure (#606)Aaron Puchert
* Prevent crashes and leaks on allocation failure Memory allocation can fail. We need to gracefully handle this case and prevent dereferencing null pointers. * Make NULL checks consistent within a file * Properly report allocation errors * Improve cleanup in pj_gc_reader.c * Implement pj_strdup and use instead of strdup The function strdup is not part of ANSI C 89, but a POSIX extension. Therefore we can not rely on it being available on all platforms.
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.

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. HALFPI is #defined as M_PI_2 (the defacto standard name). #defines _USE_MATH_DEFINES for MS Visual Studio (I didn't personally test this part, but Appveyor will not build otherwise).
2016-05-11Portability cleanups for the code in PR #6 (and a few additional source files)Thomas Knudsen
Eliminated mixed code and declarations, converted C++ style comments and probably did a few more things highlighted by running gcc with the "-W -Wall -Wextra -pedantic" flags
