2019-11-12Fix proj_assign_context()/pj_set_ctx() with pipelines and alternative coord ↵Even Rouault
operations Fixes https://github.com/OSGeo/gdal/issues/1989 pj_set_ctx() only changes the context to the main object. It should also recurse down to the steps of the pipeline and the alternative coordinate operations hold in alternativeCoordinateOperations In the GDAL use case with multithreaded reprojection, and objects being transferred between thread, this would cause a failed coordinate transformation to affect an unrelated transformation of another thread...

2019-09-05PROJStringParser::createFromPROJString(): avoid potential infinite recursion ↵Even Rouault
(fixes #1574) The exact circumstances are a bit difficult to explain, but they involve using a non-default context, enabling proj_context_use_proj4_init_rules() on it, using proj_create(ctxt, "+init=epsg:XXXX +type=crs"), whereas PROJ_LIB is defined to a directory that has a 'epsg' file in it.

Clean up time handling in helmert and deformation
2019-02-14deformation: Replace +t_obs with +dtKristian Evers
The +t_obs parameter was confusing for users since it effectively overwrote the observation time in input coordinates. To make it more clear what is the operation is doing, users are now required to directly specify the time span for which they wish to apply a given deformation. The parameter +dt has been added for that purpose. The new parameter is mutually exclusive with +t_epoch. +dt is used when deformation for a set amount of time is needed and +t_epoch is used (in conjunction with the observation time of the input coordinate) when deformation from a specific epoch to the observation time is needed.
2019-02-13Add push and pop operationsKristian Evers
This commit introduces the concept of a pipeline coordinate stack in which components of coordinates can be saved and loaded from. This makes it possible to moved values from one step of a pipeline to another, effectively overwriting parts of the output from a given step.

c6ab83f5742bc5ac6f9cb9a8b2a4f1ea241b6f63 already removed their availability in user facing application, but the library code remained, and appeared to be unused by the rest of the library, and not available to library users, the API being only in proj_internal.h. So remove all remains.

2018-03-06Remove angle brackets in include proj.hThomas Knudsen
The #include <proj.h> in proj_internal.h has been changed to #include "proj.h" in order to avoid accidentally including an old installed proj.h file while building a new version of libproj.

Remove unnecessary definitions of UV and UVW from project.h that collides with external libraries. To prevent similar problems in the future the datatypes XY, LP, UV, XYZ, LPZ and UVW has been prefixed by PJ_ in proj.h and proj_internal.h
2018-02-07Shrink PJ_XXX_INFO structs, but keep same syntax. (#775)Thomas Knudsen
* Shrink PJ_XXX_INFO structs, but keep same syntax. A number of the fixed length strings in the INFO structs are simply reflections of material that already exists as static strings at a number of places in the library (or in the case of PJ_INFO, really *should* exist, and now is implemented). This PR replaces these cases of constant length strings with const char pointers. The usage syntax is unchanged, and so is the nice property of having the return value allocated on the stack, and hence not requiring explicit memory management by the caller. proj_info now only does setup once - and the searchpath entry of PJ_INFO is not arbitrarily truncated at 512 bytes. Repeated calls simply returns a copy of already prepared material. The id, description and definition entries of PJ_PROJ_INFO are now also guaranteed to hold the entire text of the corresponding static string, by being represented by a const char pointer to that actual static string. PJ_GRID_INFO and PJ_INIT_INFO (i.e. the two smallest INFO structs) are unchanged. * Eliminate pj_strlcpy - not needed anymore: Remining calls could safely be replaced by strncpy. * Extend PROJ_INFO with paths from pj_set_searchpath. NOTE: Need to call pj_set_searchpath before first call to proj_info Huge thanks to Kristian Evers and Even Rouault for comments, debugging and advice.

2018-01-31Introduce compatibility for cs2cs-style proj-strings into the 4D API.Thomas Knudsen
Parameters such as towgs84, nadgrids and geoidgrids was previously only handled by pj_transform(). This commit add a compatibility layer in proj_create() by calling the pj_cs2cs_emulation_setup() function. This function sets up a handful of predefined transformation objects on the PJ object that is being created. Each of these transformation objects are related to the cs2cs-style parameters we are trying to emulate in the 4D API. That is, if the +towgs84 parameters is used we create P->helmert with the parameters specified in +towgs84. Similarly for +axis, +nadgrids and +geoidgrids. When these transformation objects exists we use them in the prepare and finalize functions in pj_fwd/ pj_inv. If no cs2cs-style parametes are specified we skip those parts of the prepare and finalizing steps.

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.

2017-11-27Replace some asserts by compile-time assertionsAaron Puchert
Decisions regarding the size of certain types are always made at compile time, hence this is where the assertion should take place. If the assertions fail, there is now a compiler error.
2017-11-25Overhaul ellipsoid handling (#682)Thomas Knudsen
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).
