[tox] Ensure pytest gets run with virtualenv's python

[tox] Use generating environments Drop the "env" option, which is unknown, and set a generative_ "envlist". Then use conditional dependencies based on factors_ to avoid repeating environment sections. The only singular one is the "cubicweb" environment because of its "commands". At some point, it'd be nice to find a way to have python version prefixes (py27-hooks or py34-web) for environment names but I could not find a way to extract the package name from such names. .. _generative: http://tox.readthedocs.org/en/latest/config.html#generative-envlist .. _factors: http://tox.readthedocs.org/en/latest/config.html#factors-and-factor-conditional-settings

a bit of pep8

[adapters] Use an adapter for serializing entities to a bare python structure which may be used for e.g. JSON export or other and allow to have different serializations for each entity types. Closes #6378035

[pkg] 3.20.12

[dataimport] Fallback from COPY to executemany (closes #9135780) If we can't build a suitable COPY command (e.g. because data has unsupported type), use executemany instead. Regression introduced in 3.20.0.

[web/views] unlink svg temp file after we're done Otherwise we fill up the tempdir. Closes #9133268.

Use cubicweb._

[web/views] Controllers should always return bytes Previous code breaks only on py3k.

[devtools] Fix 'newcube' on py3k

[toolsutils] Small fixes to fill_templated_file() * Use context managers to close _both_ files * Use io.open to enforce text mode on both python 2 and 3

[skeleton] Fix broken spec file template Broken in commit 73c1c9cf6bda.

[devtools] Fix fd leak in tests

[devtools] stop using datetime.now() in cwctl newcube and i18ncube

[hooks] fix timestamp confusion in DataImportsCleanupStartupHook CWDataImport.start_timestamp is inserted as datetime.utcnow(), in server/sources/datafeed.py:DataFeedSourceinit_import_log. Don't compare it to datetime.now().

[hooks] fix timestamp confusion in TransactionsCleanupStartupHook transactions.tx_time is inserted as datetime.utcnow(), in server/sources/native.py:NativeSQLSource.start_undoable_transaction. Don't compare it to datetime.now().

merge with 3.21.3 The change in unittest_serverctl.py is needed because of daef7ce08fea (from 3.20.11) and 3914388b2d0f (from the 3.22 branch). Due to both changes, CubicWebTC.config.repository no longer creates a new repository (and thus, a new connection). Since both DBDumpCommand and CubicWebTC.tearDown try to shutdown the repo, tearDown breaks apart. The solution is to temporarily disable ServerConfiguration's config cache. By forcing DBDumpCommand to get a new configuration object, it then gets its own Repo object, allowing tearDown and DBDumpCommand to work independently.
