Numerical test results based on function output, rather than mathematical derivation. Verified global coverage with graphical eyeballing through cartopy.

Before that, approximately half of the descriptions had a period at the
end, e.g. 'Cyl.' or 'Sph.' and the other half did not have those periods.
This commit drops all the dots in PROJ_HEAD descriptions.

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.

* 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

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.

Improve error messaging for cct and gie, and do some clean ups in the ellipsoid handling - partially to squash bugs, partially to improve naming consistency which, in turn, improves the readability of the ellipsoid handling code.
Renamed functions:
pj_inherit_ellipsoid_defs has been renamed pj_inherit_ellipsoid_def, while pj_calc_ellps_params has been renamed pj_calc_ellipsoid_params.
The code in get_opt (part of pj_init.c), which handles whether or not an ellipsoid definition should be dragged in from proj_def.dat, has been rewritten. I suspect this was buggy beforehand, and at least the new code is easier to follow (although it may be slightly slower, which is not really a problem as it sits in the setup code, and hence is executed only once).

* Replace pj_ell_set with reimplementation supporting ellipsoid inheritance
* remove unreachable code from pj_ell_set.c
* Swap steps, so ellps args are read first, in accordance with historical behaviour
* Add ellipsoid tests to CI targets
* Reduce some optimistic tolerances
OS/X appears to have a slightly off float handling, resulting in differences at the nanometer level. Switching to 10 nm.
|
|
* Removed remaining traces of the builtin selftest system. Moved all functionality to test/gie
* Updated Appveyor and Travis build scripts
* Another appveyor script update

* 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.

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

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).
|
|
Eliminated load time non-constant initializers, mixed code/declarations
and C++ style comments.
A lot of non-constant initializers remain in PJ_healpix. Should probably
be handled before next release.
