Before to try to optimize spot engines we need to
have some tests to bench the search duration and that
performs some checks on the results

pep8 is deprecated, it is replaced by pycodestyle.

Very useful for test purpose, we have to bench and test that endpoint
to ensure that the main feature works fine. From test part this is
easier to deal with json object.

Revert wrong encoding changes

See merge request e/cloud/my-spot!23

This patch reverts some wrong changes about
encoding from 2cc4bf3e.

Tests infra improvements

See merge request e/cloud/my-spot!22

The infra to run selenium these tests was too complex, and the test are
not updated since 2016. This patch removes the dependencies of
these tests and it adds `pytest` as runner for the unit tests.

Improved visibility of buttons in general, including pagination buttons.
Reduced the amount of space used by infobox links.
Other minor changes

Move to Python3

Closes #7

See merge request e/cloud/my-spot!16

Move spot project to python 3. The support of python 2 is
removed related to the issue https://github.com/asciimoo/searx/issues/1471.

The update is mainly done with `2to3` tool and a lot of changes for
the unicode support (see https://docs.python.org/3/howto/unicode.html)

Close: #7

Revert "Replace cgi.escape by html.escape"

See merge request e/cloud/my-spot!21

This reverts commit 0dde07cc.

some fixes about issues spotted during my manual tests

See merge request e/cloud/my-spot!20

fix tests and enable gitlab CI

See merge request e/cloud/my-spot!19

Engines was stored in set and casted in list, it leads to
issue during merge of result. This patch fixes the engines
container to a list to be able to use json serialization.

Below the error spotted:
```
   File "/usr/local/searx/searx/results.py", line 233, in _merge_result
     duplicated['engines'].add(result['engine'])
 AttributeError: 'list' object has no attribute 'add'
```

This patch removes the deprecation warning, "cgi.escape is deprecated,
use html.escape instead".

Below commands to build and run the docker image:

* docker build -t spotenv -f Dockerfile.env .
* docker run -it --rm  -v $(pwd):/ws -w /ws --network host spotenv bash -c "./manage.sh update_dev_packages; ./manage.sh pep8_check; ./manage.sh unit_tests;"

Broken since the change 7766167d.

Since 96cbb946 the supports of csv,
json and rss are removed.

introduce docker-compose to run spot in a dedicated env

See merge request e/cloud/my-spot!18

In order to run the project in a dedicated environment this
patch introduces the docker-compose file. To join redis service
a setup via an environment variable `SEARX_REDIS_HOST` is added.

Spot project does not work with the new Python client redis 3.X

To avoid to wait 10s when we stop the spot container, this
patch performs some changes to only run the python binary in the container.
Tini is included in docker itself since 1.13 or greater, so it is removed
and the environments variables are handled in the application, that change avoids
to use a bash script to patch the configuration.

Fix spacing between 'more', and language,

page images (currently missing).
