Enable optional checkers
Fix two false positives
|
|
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.

* From openjdk-7 via apt to openjdk-11 via Travis CI xenial's $JAVA_HOME
* From mingw 4.8 -> 5.3, as supported by xenial
* clang+llvm for csa kept at version 6.0.0, but for ubuntu-16.04
* Furthermore xenial implicitly has many upgrades, specifically:
- gcc 4.8.4 -> 5.4.0
- clang 4.0.0 -> 5.0.0
- cmake 3.9.2 -> 3.12.4
- python 3.4.3 -> 3.5.2
* cppcheck version kept at 1.61 (for trusty) due to many
false positives with version 1.72 (for xenial)
* Community code contribution documentation simplified to remove
version of cppcheck, as this may outdated with updates to scripts

* Split global before_install for apt and pip
* Use -qq option for apt-get, which implies -y
* Use list of targets with apt-get rather than one-per-line
* Use local variables for mingw32/install.sh
* Show version info for cppcheck, pip and python
* Simplify clang+llvm-6 path

Python3

|
- Tests should use unified diff with expected results
- Show CMake build compile commands (VERBOSE=1)
- Travis CI only has two cores, so "-j2" is sufficent

This work mostly consists of:
- a C++ implementation of the ISO-19111:2018 / OGC Topic 2
"Referencing by coordinates" classes to represent Datums,
Coordinate systems, CRSs (Coordinate Reference Systems) and
Coordinate Operations.
- methods to convert between this C++ modeling and WKT1, WKT2
and PROJ string representations of those objects
- management and query of a SQLite3 database of CRS and Coordinate Operation definition
- a C API binding part of those capabilities
This is all-in-one squashed commit of the work of
