[migration] Reserialize all constraints since yams introduce new JSON serializing format So we may drop support for older format in yams at some point.

[migration] Add IF EXISTS on DROP CONSTRAINT problem encountered on migration of a legacy database

[schema sync] Rename index when an entity type is renamed So we may still find them later using their expected name, and avoid collisions. Closes #13822045

[c-c] Add a command to check database index List indices expected by the schema but not in the database and vice-versa Closes #13822027

[sql gen] Control size of index name using an md5 hash When using concatenation of table and column, we may hit the backend size limit on index names, which results on truncated name (64 for postgres). Then we may have conflict or be unable to find expected index on later synchronization attempt. This is done by monkeypatching lgdb for now to avoid dependancy problems. Unique and primary key indices of entity types handling is left to the backend, as they are not explicitly named. See https://www.logilab.org/ticket/4789189 Closes #13821949

[sql gen] Explicitly name unique index This patch hotfix logilab database for https://www.logilab.org/6662663 and fix database creation to stop using UNIQUE in the table schema but rather create the index later on, so its name is under control. Also consider this change in schema synchronization hooks. This is preliminary work related to #13822045

Update to yams 0.44 API

[test] Fix randomness in tests

[test] Drop unused import

[serverctl] allow to sync multiple and all sources in source-sync command Breaking change: by default source are not synced anymore if it is fresh (regards to synchronization-interval). To get the previous behavior an option --force is added. Closes #13886467

[tox] Split migractions tests from server environment These are the longest tests in this environment, so running them apart (in parallel of others) would hopefully speed up the whole suite.

[dataimport] Fix rdef loopup in importer

[py3k] left-over unicode() in authobjs.py

[server] Improve massive deletion of entities sqlserver is limited on the "IN" array size and produce an error "The query processor ran out of internal resources and could not produce a query plan". The exact limitation is unclear but can occur with > 10000 item in the array. See https://support.microsoft.com/en-us/kb/288095 Now we process the deletion by batch of 10000, some quick benchmarks show that there is no performance impact: delete_in(50000): 46.765182972 delete_in_batch(50000): 46.3242430687 delete_in(100000): 62.2969429493 delete_in_batch(100000): 61.8402349949

[hooks] Add a bunch of tests for session synchronization And change unicode into six.text_type in authobjs.py spotted by new tests.

[entities] Drop very old backward compat from erudi time (even the standard datetime type didn't exist at that time)

pep8 + docstrings and comments improvments

[server] some pep8 in rql2sql

[dataimport] Deprecate SQLGenObjectStore Closes #10338709.

[datafeed] attempt to acquire synchronization lock even when force is given instead of the implementation in e717da3dc164, raise an error if the lock is already grabbed and catch this error in the caller. See discussion on https://www.cubicweb.org/revision/10790765 Closes #10451635

[schema] Cache RQL expressions on schema loading Add a mapping rql string to rql statement Deserializing schema is ~36% faster with a lot (> 4000) expressions like those generated by cubicweb-container.

[schema] Avoid parsing RQL expressions twice on schema loading Kill full_rql (unnecessary) Use snippet_rql rather than rqlst when possible Don't access to rqlst cachedproperty from __init__ Deserializing schema is ~40% faster with a lot (> 4000) expressions like those generated by cubicweb-container.

[dataimport] Handle Bytes data in ExtEntity and convert them to Binary Closes #13887276.

[test] Avoid assertCountEqual in unittest_syncschema.py It's not clear why this happens, but it seems that assertCountEqual does strange things with unittest2 on Python 2 for equality comparison (trying to sort constraint objects, even though BaseConstraint raise NotImplemented in __lt__ from Yams 0.43). So just avoid using it to get this test passing.

[packaging] Bump version number

[web/session] make sure not to modify an inner value of session.data (closes #11217958) When we modify a mutable value stored in the session's data (dict-like object) we prevent an alternative session data handler (eg. pyramid-redis-session) from detecting this update and synchronizing it in its backend (like redis).

[book] improve a bit the documentation of the database setup also remove the MySQL section.

[doc] add documentation for specializing translation of other cubes in an application cube

[doc] fix some URLs (cs to test jenkins autobuild )

[uicfg] Fix typo in set_fields_order

[forms] We don't want cwjs-edition-cancel class on reledit's cancel button Else it's bound to a js function that collides with onclick provided by reledit code. Closes #13120795

[test] Prefer unittest.main
