[doc/changes] document that legacy cube support has been dropped

[doc] replace legacy import to new style cube import in various places

[web/views] drop deprecated module cubicweb.web.views.timeline

[web/views] drop deprecated module cubicweb.web.views.massmailing

[web/views] drop deprecated module cubicweb.web.views.isioc

[web/views] drop deprecated module cubicweb.web.views.embedding

[web/views] drop deprecated module cubicweb.web.views.igeocodable

[pyramid/core] drop fallback import of legacy cubes

[cwconfig] drop importing legacy cubes This finally drop support for legacy cubes. In cwconfig, don't load modules in the "cubes" namespace. In cube_pkginfo() handle CW_MIGRATION_MAP which wasn't working with new style cube. Drop all method specific to legacy cubes importer: cubes_search_path(), extrapath(), cls_adjust_sys_path() Drop environment variables related to legacy cubes: CW_CUBES_PATH and CW_CUBES_DIR

[doc] better documentation for "cubicweb-ctl newcube" cubicweb-ctl newcube create cubicweb-<name> in current directory.

[test] make unittest_cwconfig.py does not depend on legacy cube machinery By dropping legacy cube tests in various places.

[devtools/test] drop legacy cube i18n tests test_i18ncube_legacy_layout() is droped and make others tests uses a new style cube "cubicweb_i18ntestcube", so it doesn't depends on legacy cube machinery.

[server/test] make unittest_migractions.py use new style cubes MigrationTC used old cube layout in cubicweb/server/test/data-migractions/cubes, move them to new style cubes as "cubicweb_<cubename>" in "apphome" (cubicweb/server/test/data-migractions/) which is added to PYTHONPATH by CubicWebTC.

[cwconfig] drop _cube_modname Since we drop support for legacy cubes, this is equivalent to _cube_pkgname()

[cwconfig] drop legacy cube importer We don't want to support legacy cubes anymore.

Drop more deprecated code This follows up on changeset a8c1ea390400, in which code deprecated using logilab.common.deprecation got dropped. Now we also drop code deprecated using stdlib's warn(<msg>, DeprecationWarning). Notice that, as a consequence of dropping old/new etypes aliases in cubicweb/schema.py, we drop the import ETYPE_NAME_MAP (no longer needed); but since other modules imported that name from cubicweb.schema, we need to update the import statement to use "cubicweb" directly.

Flake8 cubicweb/cwvreg.py

Drop deprecated "boxes" and "contentnavigation" registries

Drop deprecated CWCache entity type

Update i18n after "recent" changes

Drop repair_file_1-9_migration.py

Drop a left-over 3.22 deprecation warning

[doc] fix reference to ~src/cubes in tutorial ~src/cubes refer to the $HOME/cubes directory of "src" user while ~/src/cubes refer to $HOME/src/cubes directory of current user.

[doc] replace cubicweb-ctl start by cubicweb-ctl pyramid Since twisted support is gone.

[doc] make the tutorial use a python3 virtualenv

[doc] Update README "Getting started" * install using pip and with pyramid in a virtualenv * link to pyramid.ini documentation * Use pyramid to start application since twisted support is gone

Flake8 cubicweb/devtools/httptest.py

Remove Twisted web server Twisted web server is not used anymore and has been superseded by pyramid many years ago. Furthermore, our usage is not compatible with Python 3. So we drop the "etwist" sub-package. As a consequence, "all-in-one" configuration type gets dropped as it was Twisted-specific. We resurrect it in cubicweb/pyramid/config.py by only keeping options used by the "pyramid". Similarly, we introduce a AllInOneCreateHandler in cubicweb/pyramid/pyramidctl.py that is basically the one that lived in cubicweb/etwist/twctl.py and is used to create the "all-in-one" instance. Added a TODO here about "pyramid.ini" that could be generated at the end of bootstrap() method. In cubicweb/devtools/httptest.py, CubicWebServerTC is now equivalent to CubicWebWsgiTC and the latter is dropped.

Separate twisted-specific configuration from WebConfigurationBase class This is in preparation of dropping the Twisted web server backend. We thus draw a clearer line between what's specific to twisted from what's generic by moving WebConfigurationBase class into cubicweb/web/webconfig.py and only keeping twisted-related in AllInOneConfiguration (still living in cubicweb/etwist/twconfig.py).

Flake8 cubicweb/web/webconfig.py

Flake8 cubicweb/etwist/twconfig.py

Remove ctl commands using the Twisted backend This backend is not maintained, very likely no longer used in any recent instance, and not supported in Python 3.

Flake8 cubicweb/cwctl.py * run autopep8 on the file * fixed unused imports * rename "version" import as "cw_version" in order not to shadow local variables

Remove _handle_win32() method from "create" command class This method generates code in a file using etwist module that we are about to drop.

Skip tests for ldapsource with python >= 3.7 Until someone works on fixing these, this should make our CI green again. I tried to use setupModule() to check for python version, but pre_setup_database() is apparently called even when a SkipTest exception is raised there. So handle this in that method.

[doc] Update cubicweb-ctl page about how to run an instance * remove mention of start/stop/restart/status commands that do not exist anymore * briefly mention the "pyramid" and point to respective documentation page * mention that a WSGI server should be used in production

[doc] Drop mention of the "pyramid" cube This cube got merged into cubicweb several versions ago.

[cli/enh] on 'shell' or migration command, use ipython if available

[web/test] drop dependency on third party cubes Drop dependency on cubicweb-file, cubicweb-blog and cubicweb-tag for cubicweb/web/test Copy required parts of cubes (schema, entities, views and hooks) into cubicweb/web/test/data/cubicweb-<cube> that make tests pass.

[test] drop dependency on third party cubes Drop dependency on cubicweb-file, cubicweb-localperms, cubicweb-tag and cubicweb-comment for cubicweb.test and cubicweb.sobjects.test Move cubicweb/test/data/libpython/cubicweb_* to cubicweb/test/data, so it's included in PYTHONPATH. Add missing parts of schema, entities, views, hooks that make tests pass.

[test] drop CubicWebConfigurationWithLegacyCubesTC This is used to test legacy cube import which is planned for removal in cubicweb 3.27, so drop the code.

[test] drop unittest_cubes.py This is used to test legacy cube import which is planned for removal in cubicweb 3.27, so drop the code.

[server/test] do not depend on third party cubes Drop requirement of basket, card, comment, file, localperms and tag cubes for cubicweb.server tests. Copy needed part of schema, entities, views, hooks into the cubicweb/server/test/data directory (which is included in PYTHONPATH for CubicWebTC tests). For migration tests which use different "datapath", use symlinks to have dependent cubes importables.

[server/test] drop unused variable initialization in OperationsTC.setUp() Variable "self.hm" is unused

[server/test] bootstrap config in setUpModule function This is test initialization, so use the setUpModule function for this

[schema] drop monkeypatch "name_for" on BaseConstraint BaseConstraint doesn't have "name_for" method, this is just an addition for cubicweb needs. Implement this as a function instead of a monkeypatch to avoid having "name_for" not defined because cubicweb.schema hasn't been imported. In particular this fix running cubicweb/server/test/unittest_schema2sql.py::SQLSchemaTC::test_known_values alone.
