travis/osx/before_install.sh: do not install md5sha1sum from brew

2019-12-16T21:13:32+00:00

travis/osx/before_install.sh: attempt to fix 'pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.'

Rearrange Travis CI scripts to be more modular

2019-09-24T23:16:27+00:00

* 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

Travis: add testing of JSON output against schema and upgrade everything to Python3

data/Makefile.am: add detection of md5sum utility, and install md5sha1sum on MacOSX Travis

autoconf build: add a PROJ_DB_CACHE_DIR trick to speed-up builds

2019-04-28T20:09:03+00:00

If the PROJ_DB_CACHE_DIR environment variable is defined, then a
$(PROJ_DB_CACHED_DIR)/proj.db.sql.md5 file is used to determine if
the set of .sql files has changed since the last time. If not then
$(PROJ_DB_CACHED_DIR)/proj.db is directly used.
This can saved a few seconds when doing rebuilds.
This is a poor man equivalent of ccache for generating the database :-)

Implement RFC 2: Initial integration of "GDAL SRS barn" work

2018-11-14T21:48:29+00:00

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
https://github.com/OSGeo/proj.4/pull/1040
