[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.

Ask sqlite to check foreign keys Related to #4846892

Add reference from etype table's eid column to the entities table Related to #4846892.

[server] change order of entities table modification vs entity creation/deletion In order to have a foreign key referencing the entities table, the insertion into entities must happen first, and the deletion must happen last. For the deletion case, this means we need to: 1. delete all relations (cascade) 2. delete the entities themselves 3. delete the corresponding lines from the entities table This means the _delete_info{,_multi} methods can't keep doing 1 and 3. Thankfully the "public" delete_info method appears to be unused, so drop it. Related to #4846892.

Use foreign keys for relations tables Closes #4846892

Add foreign key for inline relations Related to #4846892

Use our version of schema2sql Related to #4846892

Steal schema2sql module from yams It has no user inside yams, and we need it here if we want to be able to reference the (cubicweb-only) entities table from other tables. Related to #4846892

[dataimport] fix pylint detected error in SQLGenObjectStore

[restore/portable] properly restore the numrange generator If the dump format version is 1.1, read and restore numranges. Closes #4870338

[backup/portable] properly write the eid numrange generator (the eid is no more a sequence) Bump format version to 1.1. Related to #4870338

Added tag cubicweb-version-3.20.4, cubicweb-debian-version-3.20.4-1, cubicweb-centos-version-3.20.4-1 for changeset 49831fdc84dc

[pkg] 3.20.4

[schema] set permissions that do not allow edition on computed relation. Closes #4903918 Also, drop 'del schema' from test which clutters the code for no benefit.

[computed attribute] ensure attribute's formula apply only to the correct type. Closes #4901163

[schemaserial] fix detection of CWComputedRType table, closes #4901150

[dataimport] source.add_info doesn't take anymore a 'complete' argument Closes #4891550

[dataimport] massive renaming of session to cnx and make NoHookObjectStore working with the new connection handling. Closes #4891547
