[server] Make sure 'zmq-address-sub' config is always iterable

[web] split timeline in an individual cube Closes #1279544

[devtools] don't hide warnings and errors during tests The markdown module in jessie turns all warnings into logging calls, so this allows me to still see deprecation warnings when running tests.

[test/i18n] remove unneeded hack

merge 3.19.10 into 3.20

[server/session] Fix typo "meta vs. metas" in describe()

Added tag cubicweb-version-3.19.10, cubicweb-debian-version-3.19.10-1, cubicweb-centos-version-3.19.10-1 for changeset 3bab0b9b0ee7

[pkg] 3.19.10

[i18n] Update translations Related to #5012581.

[config] Lowercase the FQDN we get from the OS (closes #5040345) Browsers convert the host name part of URLs to lowercase. This has the unfortunate effect of triggering various CORS error messages in CubicWeb (because the Origin: header will contain lowercase letters). As per RFC 4343, host name comparison should be case-insensitive. So let's put it in lowercase when we grab it from the host system. If admins put uppercase letters in "host" or "base-url" in their all-in-one.conf, then it's their fault.

[web/views] Honor 'action' attribute on AutomaticEntityForm, closes #4943392 On AutomaticEntityForms, get_action used to bypass the logic from FieldsForm.form_action() which handles the 'action' attribute itself, preventing callers from overriding it at selection time. This capability is used by the inlinedit cube. In a nutshell, we let the deprecated AutomaticEntityForm.get_action() raise an AttributeError, which allows FieldsForm.form_action() to handle it properly.

[docstrings] fix project-wide English language mistake Even though 'u' is a wovel, it may be pronounced 'yu' which is a consonant sound. In such cases precede it with 'a' instead of 'an'.

[doc] Don't pretend we know cubicweb runs on mysql As far as I know it hasn't been tested in years.

[test/i18n] Update reference po file following 75cd7df5c32e This changeset added a (missing) message "add a <etype>", so reference po file needed an update.

[devtools] add a method on CubicWebTC to fake data posted by standard cw forms. Closes #4985805

[web/wdoc] fix links They're relative to ${base-url}/doc/, not ${base-url}. Closes #3161099.

[i18n generation] add missing 'add a EntityType' message to generated catalogs. Closes #5012581

[server/test] fix test_zmq We were only asserting in a thread, thus ignoring the results.

[views,js] remove user_callback feature Related to #3975260.

[newcube] Make the generated code PEP-8 compliant Closes #4925396

Remove unused imports

[ext] Remove use of cStringIO We create a StringIO never to read anything from it. Docutils seems to support setting the 'warning_stream' to False to ignore warnings. So let's just do that.

[view] Use io.BytesIO as stream for binary views

[undo/test] check that the entity was restored even though the fiche relation wasn't

Use a moved_entities table to record external entities moved to the system source Instead of using a negative eid in the entities table, move the record to a new table so we don't have an interval with a missing eid in entities. Related to #4846892

Add unique index on entities.extid

[undo/test] if we try to delete an entity referenced by an inline relation, we fail

[undo] when we can't undo an inlined relation change, point at None, not a broken eid This whole thing is "a bit" weird.
