This commit is the result of the squashing of rfc4_dev branch in a single
commit. It implements mostly RFC 4 related work.
* Grid handling:
- remove obsolete and presumably unfinished implementation of grid catalog functionality
- all grid functionality is in grids.cpp/.hpp
- vertical and horizontal grid shift: rework to no longer load whole grid into memory
- remove hgrids and vgrids member from PJ structure, and store them in hgridshift/vgridshift/deformation structures
- build systems: add optional libtiff dependency. Must be explicitly disabled if not desired
- add support for horizontal and vertical grids in GeoTIFF, if libtiff is available
- add GenericShiftGridSet and GenericShiftGrid classes, relying on TIFF grids, that can be used for generic purpose grid-based adjustment
- add a +proj=xyzgridshift method to perform geocentric translation by grid. Used for French NTF to RGF93 transformation using gr3df97a.tif grid
- deformation: add support for +grids= for GeoTIFF grids
- horizontal grid shift: fix failures on points slightly outside a subgrid (fixes #209)
* File management:
- add a filemanager.cpp/.hpp to deal with file related work
- test for legacy proj_api.h fileapi
- proj.h: add proj_context_set_fileapi() and proj_context_set_sqlite3_vfs_name() (fixes #866)
- add capability to read resource files from the user writable directory
* Network access:
- build systems: add optional curl dependency
- add a curl-based default implementation for network related functionality
- proj.h: add C API to control network functionality, and optionaly provide network callbacks
- add data/proj.ini with default settings
- add a SQLite3 local cache of downloaded chunks
- add proj_is_download_needed() and proj_download_file()
* Use Win32 Unicode APIs and expect all strings to be UTF-8 (fixes #1765)
For backward compatibility, if PROJ_LIB content is found to be not UTF-8 or
pointing to a non existing directory, then an attempt at interpretating it
in the ANSI page encoding is done.
proj_context_set_search_paths() now assumes strings to be in UTF-8, and
functions returning paths will also return values in UTF-8.

Should fix the issue reported in https://lists.osgeo.org/pipermail/proj/2020-January/009188.html
Some extra north-american grids present in data/ can affect the results of
some tests, so create a data/for_tests/ subdirectory in which we copy only
select grids.

For reasons unknown to anyone but the geniuses from Redmond: In
MSWindows, the wildcard pattern "*.gie" expands to all files having
an extension *starting* with ".gie".
In other words "dir *.gie" will list files with extension ".gie"
*and* with extension ".gie_failing".
This means that running "gie test\gigs\*.gie" will run all gigs
tests, even the ones known to fail.
So rather than getting a quick check for regressions, one gets
a lot of noise and no easy way to be sure whether any regressions
have appeared.
To work around this oddity, we rename all files ending in
".gie_failing" to end in ".gie.failing" - and while at it,
adding all the non-failing gigs tests to the AppVeyor test suite.
This extends the regression test suite, run at the end of each
AppVeyor integration, to over 2500 individual tests.
Test coverage, however, is still hovering just below 75%, so
there's still plenty of room and reason for additional tests.

All the GIGS JSON files have been converted to the gie format
and are now covered by running "make check". Therefore we no
longer need the Python setup. Removing it from the Travis CI
setup should speed up the test execution time a bit.
|
|
Make sure that the gie files in test/gie and test/gigs are included
in the distribution tarball. Tests with gie are set up to run all
available files matching *.gie in the gie and gigs directories. For
this reason tests that are known to fail in gigs/ have been renamed
to *.gie_failing, so that "make check" can be run in-tree in local
copies of the git repository.

The GIGS tests that are known to work are added to the CMake test
setup. The GIGS gie files have been auto-translated from the
existing json-files and some corrections to tolerances have been
necessary since gie uses different norms than GIGS specify. The GIGS
tolerances are specified as the infinity norm of angular coordinates,
whereas gie uses the actual distances between calculated and expected
coordinates (using geodesics). In a few tests +towgs84 is overriden
from the EPSG inits to avoid creeping numerical inaccuracy in
roundtrips.

Python 3.x, the zip function is iterable, which caused Python 3.x to miss some coordinate tests. Add cli argument '--test' to test_json.py to only specify one test type (conversion/roundtrip) to be ran. Change Travis testing to only perform conversion test on some JSON test files.
