It should no longer be needed because erp5.util should now have the fix
from
nexedi/erp5@97f3310e

so that we don't have to escape % as %%

Major change is that slapos compatible wrapper is no longer installed in
parts/firefox/firefox-slapos , but directly as "firefox" in the
buildout:bin-directory of the software profile.
geckodriver is also in the same buildout:bin-directory.
This way, softwares using this just need to add
buildout:bin-directory to $PATH

Adjust seleniumrunner and jstestnode for the changes

Also drop unused firefox 45

Jérome changes from original 8cf6908df752b9e7632b2910ffc85027f1f4f22c :
 - name section [firefox-install], because including the version in
section name means we have to also update section name when we update
version.
 - use same version, the "versions up" will be separate commits.
 - now that seleniumrunner and jstestnode are using buildout.hash.cfg,
md5sums are in separate files.

Otherwise instanciation can finish too early.

We don't want runUnitTest is to listen on 127.0.0.1, as it is not
allowed for SlapOS instances, runUnitTest wrapper is extended to include
`--zserver` with a pre-assigned ip:port.

runTestSuite starts several test in parrallel (controlled by
`--node_quantity` argument, which is passed by erp5testnode), so we need
to make sure that we provide it with enough ip:port. For this, we
extended runTestSuite with a `--zserver_address_list` argument and we
generate a wrapper with a list of pre-assigned ip:ports. The length of
this list is also controlled by `mariadb.test-database-amount` instance
parameter (eventhough it's slightly different).

Because zelenium tests needs to access this zserver over a secure origin
(otherwise modern browser features such as service worker are not
available), add an https proxy in the apache from the balancer
partition.

runUnitTest and runTestSuite have been extended with resp.
`--zserver_frontend_url` and `--zserver_frontend_url_list` arguments and
the URLs published by the balancer paritions are set in the wrappers.

This introduces a circular depencency, balancer partition needs to know
the address of the testrunners and zope partitions needs to know the
URLs of the corresponding http proxies on the apache. This is is handled
by `slapos.recipe:publish-early`:

 1. request zope family with an empty `test-runner-apache-url-list`.
    zope is instanciated a first time.
    zope returns `test-runner-address-list` ( a list of (host, port)
    tuples )
 2. request balancer with `test-runner-address-list`
    balancer is instanciated.
    balancer returns `{{ family_name }}-test-runner-url-list` ( a list
    of apache URLs ), which are published in the root partition.
 3. zope family is re-requested with
    updated`test-runner-apache-url-list` information

instance-erp5.cfg.in template was also reorganised to move
`[publish-early]` next to `[publish]` at the bottom of the file.

Document the existing behavior that setting mariadb.test-database-amount
to 0 disable the creation of testrunner.

`enable_authentication` parameter of `backend-list`
was not documented.

This release should be now stable enough for release

It is combination of requestoptional and serialised.

In order to avoid needless inheritance create JSONCodec and use it, also
with renaming Serialised to RequestJSONEncoded.

Also provide a test asserting that important log is seen in case if no expected
return is set.

Add testfixtures module to catch logging.

if saucelabs_dict is present, then generate delegate runTestSuite to launch test with saucelab
else default one is created

  it  clean up....

  Up to some extent we would like to set diskcache=none and diskaio=native

This reverts commit 2c79bee1 because it depends on rdiff-backup version 1.3.4nxd4 which is not stable yet.

This reverts commit 9b3dfa01

On runner importer script, when updating database, set timeout to 5 seconds (same value as the default in python sqlite3 module: https://docs.python.org/2.7/library/sqlite3.html#sqlite3.connect). If database is locked by another process we wait a bit instead of raise immediately "database is locked". Importer script will raise if database is locked for more than 5 seconds.

they are already pinned in stack/slapos.cfg

When slapos.libnetworkcache is not installed, then shacache is not
enabled, so SR will no longer build when there's a dead link.
