ZODB Components: Resetting Portal Type classes was also clearing Interfaces of erp5.component.* modules.

__implemented__ and __provides__ attributes are cleared on Portal Type reset
to break a circular reference (11e2b506). Resetting of ZODB Components is
done independently of Portal Type classes, so until the next ZODB Component
reset, Interfaces were not implemented anymore.

11e2b506 states that this creates a memory leak but this is not actually true
as Python garbage collector will break such circular reference and collect
this object, as asserted by a newly introduced Unit Test. This is probably
less efficient than explicitly breaking the circular reference and thus relies
on reference counting (rather than the garbage collector) but doing otherwise
would require introspecting ZODB Components module to find classes implementing
Interfaces (erp5.portal_type only contains classes).

This only takes care of ZODB Components modules but maybe breaking circular
references for Portal Type classes is not even needed (if so, this will be done
in a later commit).

ZODB Components: When migrating FS Mixin, set the ZODB Component reference to the class name (like Interfaces).

ZODB Components: Non-core bt5 with 'Document Component' overriding standard ERP5 Document must create its own version_priority.

Otherwise this will clash when standard ERP5 Document will be migrated to ZODB
Components to erp5_base.

Like Document and Interface Components for the same reasons (694c9fee).

Since 264ded5c in ERP5JS we render the form directly after a successful edit, but this was done sometimes too early, namely, the next form was rendered before interaction workflows and this leads to problems like the ones discussed in nexedi/erp5!982 (comment 92893)

This test click on the delete button which deletes by an ajax request
and immediatly after open the "wait for activities" page. Sometimes the
second request starts before the first is committed, so there are no
activities to wait for.

When using ZServer, we had only one worker thread, so this was not
visible, but with wsgi we have more than one so it happened sometimes.

Use an old jQuery trick to wait that the first request is no longer in
flight.

SameSite=None breaks the compatibility with some browser versions.
https://www.chromium.org/updates/same-site/incompatible-clients

We choose Lax and not Strict so that we can open links to ERP5 from
external applications and so that OAuth Logins work. Implementing the
"two cookies, one for read one for write" approach suggested in
https://tools.ietf.org/html/draft-ietf-httpbis-rfc6265bis-02#section-8.8.2
would be too big change at this point.

Allow instances to surcharge the SameSite value for some specific domains if needed,
by surcharging the ERP5Site_getAuthCookieSameSite script.

We want to render the next page after interaction workflows are
executed.

This uses a foo_interaction_workflow that sets a short title when title
is set to a special value. We use it to check that when user set the
title to that special value and save, next time the form is displayed,
the values displayed are the ones after interaction workflow modified.

This is a simple and a bit unrealistic scenario, but we have for example
interaction workflows that update security definitions when some
properties are modified, we want the next form to display the values
after modifications.

This is also the case of editions of portal components which sets the
document to "modified" state and "re-validate" it at the end of
transaction, unless pylint detects error.

action added in a previous commit was removed, probably by mistake
because only the metadata was removed.

workflows were not sorted and some metadata files have an extra \n,
probably because of manual edit

This uses a different approach that what I was using in the past. I'm no longer trying to rename skins that does not match our naming conventions, but just adding them the the "ignore list".

This would still allow to detect when new wrongly named scripts are introduced without risking regressions when we rename a script that was used from some places we did not change (like project customisations).

This was a false positive

We should be able to configure a group calendar saying that the pattern
is "from 9:00 to 12:00, repeat every monday morning" with a group
calendar assignment saying "use this pattern from 01/01/2016 until
31/12/2016" and then create another group calendar assignment for 2017
without having to change the periodicity stop date on all presence
periods of the group calendar.

I think it should repeat from group calendar assignment's start date
until min(group calendar assignment's stop date, presence period's
periodicity stop date).

Shared parts received from test node will be passed as
SLAPOS_TEST_SHARED_PART_LIST environment variable to egg tests.

This will be useful for SLAPOS-SR tests.

Some test suites who install software during the test, such as SLAPOS-SR
tests, could benefit from reusing already installed shared parts.

The convention is that --shared_part_list is a os.pathsep (:) separated
list of paths of read-only shared parts in which the test is not allowed
to write.

Shared parts speed up compilation time and is becoming the standard in
SlapOS software installations, so it makes sense to use it in our test
nodes, as it also gives one more opportunity to test this feature.

erp5testnode configuration file supports a new shared_part_list option,
that can be set to a \n separated list of paths to use for shared parts,
following the same rules as slapos.core and slapos.recipe.cmmi (ie. the
first ones are read-only and the last one is read-write).

This shared_part_list option will be set in slapos.cfg used to compile
both the "software for testnode" (ie. selenium-runner) and later the
softwares under tests.
The software under tests will also use a local directory for each test
suite to install shared suite.

The directory structure is now:

  srv/
    shared/
      (shared parts to install selenium runner)
    slapos/
      soft/
        (selenium-runner software)
    testnode/
      foo/ # test suite with reference foo
        inst/
          (partitions of tested software)
        shared/
          (shared parts to install tested software)
        soft/
          (tested software)

and in the configuration srv/shared will be set as initial
shared_part_list.

When installing selenium-runner, srv/shared/ is used to write shared
parts. These shared parts are never removed.

When installing software under test, srv/shared/ and
srv/testnode/foo/shared/ are used. If parts are found in srv/shared they
are used, if they are not found, they are installed in
srv/testnode/foo/shared/.

In practice, this should mean that the shared parts installed by
selenium-runner will be reused for all tested softwares and this should
speed up initial installation of these softwares.

Currently, nothing is implemented regarding removal of unused shared
parts, but in our case:
 - srv/testnode/foo/shared/ will be removed when "foo" is removed.
 - srv/shared/ should be used only when installing selenium-runner.

If this starts to use too much disk space, one quick and dirty
workaround could be to destroy the test node instance and re-create it.

Use monaco editor with https://github.com/joe-re/sql-language-server
completion provider bundled in
https://lab.nexedi.com/jerome/monaco-editor-sql-completion-provider
This completion provider is not perfect, but codemirror's one was not so
good either. At least we can use monaco editor.

Also add a quick "copy to cliboard" feature, which copies the table as
html or in markdown format for text.

And also fix Server-Timing header that was an obsolete syntax no longer
supported by chrome.

were not enough, exceptions set on days were calendar did not repeat
were also confusing other exceptions after this.

Simplify implementation a lot, instead of keeping track of the next
exception date, start by building a set of all exceptions dates and
use membership of this set as a criterion to skip exceptions.
