PROJ/travis/before_install.sh, branch 8.0.0

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

2019-07-07T22:05:01+00:00

Disable status bars from 'pip install'

2019-04-05T04:47:34+00:00

Also simplify language for .travis.yml

Remove GIGS Python test suite.

2018-02-02T11:09:04+00:00

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.

Remove all occurences of python3 from CI scripts since it is not in use

2017-10-13T16:54:07+00:00

Use Python2 in favour of Python3 which behaves inconsistenly on Travis (#573)

2017-09-21T11:23:42+00:00

Use python 3.5 with pyenv

2017-09-20T13:02:42+00:00

Make sure all platform specific before_install scripts call the global before_install script. Python version setup moved to global before_install script.

2017-09-12T10:38:26+00:00

Move python version setup to build matrix. Different Travis platforms seem to have different setups. This should take care of the differing python setups between linux and osx.

2017-09-12T09:22:53+00:00

Set python version to 3.6 with pyenv
