[pyramid] Rename paste app factory to pyramid_main Making it clearer that this would build a Pyramid application, just in case we eventually provide other means to create a WSGI application than Pyramid.

[tox] Do not use site packages in testenv This is the normal way of running tox. We used to set this because some people liked to run tests using packages installed by other means (i.e. system-wide). Now, there seems to be a consensus that running tox without site packages is a better idea, in particular since many of our dependencies are now available as wheels and thus would install quickly provided one uses a recent pip/virtualenv.

[test] Add user-site to PYTHONPATH before installation of new cube in test_newcube_install Otherwise, setuptools complains that the target installation directory (i.e. "user site" is not in PYTHONPATH). This is probably because we use a fake HOME with --user install option. Failure shows up when running tests through tox without system site packages (see next patch).

[web/views] deleteconf: ignore workflow when displaying composite entities This hide TrInfo composite entities when deleting an workflowable entity.

[rset] Use RQL cache in syntax_tree method This avoid several unnecessary parsings per HTTP request, since in most case rset's rql is in the rql cache (since it has just been executed), while yapps based parsing is known to be slow.

[repo] Introduce a clear_caches method on the Querier class that is called from repository's clear_caches.

[repo] Consistent API for cache clearing clear_caches, reset_caches, clear_eid_caches are now all named 'clear_caches' with optional eids/etypes arguments to clear eid specific cache entry,

[repo] Extract rql cache handling to a dedicated class

[sobjects] Fix a trivial flake8 error

[repo] Drop cache clearing methods from the source interface Those are actually system source specific.

[repo] Move and rename repo._clear_planning_cache to make it clearer it's clearing the @cache of source_defs method.

[sobjects] Fix flake8 errors in services.py

[test] Rename BaseQuerierTC._access to BaseQuerierTC.admin_access so it's consistent with CubicWebTC and avoid access to a protected attribute which has been exposed by the removal of the 'session' property a few csets earlier.

[repo] Fix flake8 error

[pyramid] Add a "pyramid" instance configuration type In a new module 'cubicweb.pyramid.config' we define a "pyramid" instance configuration type. The noticeable feature of this configuration is that it manages a 'development.ini' file that gets installed in application home (along with `.conf` file). This file is templated and includes generated values for secrets of session and authtk tokens. This means that we can just call: pserve etc/cubicweb.d/<appname>/development.ini or gunicorn --paste etc/cubicweb.d/<appname>/development.ini -b :8080 just after instance creation to get a pyramid instance running without having to hack around a 'pyramid.ini' file. This patch drops 'development.ini' from skeleton and moves it in cubicweb/pyramid so that it gets installed at instance creation which is more appropriate than in cube creation. The new configuration class sets "cubicweb.bwcompat" setting to false so it is not intended to replace the "all-in-one" configuration type (which would require a bit more work). This configuration is close to the the 'repository' configuration type with just a couple of options from WebConfiguration that are needed for Pyramid (anonymous user/password plus some miscellaneous options that I'm not so sure are really needed). Note, in particular, that we do not pull CORS settings to be injected as a WSGI middleware like in wsgi_application_from_cwconfig() since I believe this should be left as an end-user responsibility and since this can be defined in a standard way in paste configuration. This configuration inherits from ServerConfiguration but registers the same appobjects as WebConfiguration. In cubicweb.web.request._CubicWebRequestBase, we guard against access to "uiprops" and "datadir_url" of the config because this new "pyramid" config does not have these (this does not make sense without bwcompat mode). At some point, we should either avoid using `cw_request`'s pyramid request attribute or make cubicweb's web request really independant of existing implementation and drop these assumptions.

[pyramid] Call repository's shutdown method atexit This way when run through a WSGI server (pserve, gunicorn, etc.) we make sure that the repository is properly shut down. In particular, this would wait for threads to terminate (otherwise, they'll be killed).

[querier] Turn repo.querier_cache_key into a private function of the querier module, only place where it's used.

[cleanup] Fix flake8 errors in web/application.py and associated test

[test] Simplify CWTC's init_authentication and assertAuthSuccess which shouldn't rely on removed .session attribute while it's not necessary and could be written in a simpler way.

[cleanup] Drop non sense sentence in docstring

[repo] Drop Session at last This is not used at all anymore.

Fix flake8 some errors

[test] Use existing reference to repo_source

[repo] Drop repo.new_session method we should not go through Session to create Connection anymore. This is unofficial API, no backward compat for now.

Stop using Session on the repository side Only expect session on web request, and let the web session/authentication managers provide them. Access to cnx.data, which used to return session data, is deprecated: there is no more access to session data from the repository side, and they should be access from req.session.data from the web side.

[test] Drop unnecessary call to new_session This is not unittest, the above call is enough.

[user] Drop ugly hack on CWUser entity class which should be not necessary anymore, beside two remaining usage in our own test suite.

[test] Use user_session_cache_key function to generate cache key.

[session+test] Stop storing / accessing session when it's not necessary

[devtools] Stop relying on Session to create connection in RepoAccess

[devtools] Stop using repo.new_session

[session] Kill support for a 'session_open' hook event To be consistent with dropping of the 'session_close' event, and also because this is already not called when using pyramid.

[devtools] Rename FakeSession into FakeConnection because it is what it is.

[cleanup] Drop references to the old internal_session method dropped a while ago, no need to talk about it in a docstring nor to fake it.

[session] Drop unused class

[cleanup] Drop no more used parse_repo_uri function

[server] Fix flake8 error of test/data/hooks.py

[repo] Drop repo.connect backward compat use new_session instead (introduced in 3.19 iirc)

[session] Drop no more necessary Session.sessionid and Connection.connectionid

[repo] Kill repo._sessions and with it the need to have a looping task to clean it up, and with that all the session's timestamping machinery.

[repo] Stop closing session The only point in "closing" session is to call the `session_close` event. Since I'm not aware of any application relying on it, I think this is too costly (in term of code) to maintain and propose to drop it.

[views] Stop giving stats / debug information relying on _sessions This is already broken when using pyramid anyway.

[session] Stop relying on _sessions to synchronize living session by doing what we currently do in pyramid. Also, attempt to synchronize CWUser's class sounds like a dark corner case handling that should be removed in favor of short lived user objects (beside it shouldn't occur except during migration).

[test] Drop useless access to repo._sessions test still succeed afterwards.

[repo] Fix flake8 errors in server/__init__.py

[repo] Drop no more used ShuttingDown exception

[repo] Drop _get_session method it's not actually necessary but holds underlying _sessions dict handling. Drop backward compat relying on it (which IMO should not be a problem). Drop import of unused QueryError along the way.

[test] Drop call to CubicWebConfiguration.load_cwctl_plugins in unittest_cwctl.py This is no longer need now that we call load_available_configurations() in the "list" command (see 5e7282bdf140).

[web] Extract a base class out WebConfiguration This will be used to build a CubicWebPyramidConfiguration in following changeset.

[tox] Drop reference to removed init_instance.py file in flake8-ok-files.txt The file got removed in 1b9fd8bda1cd.

[web] Put 'use-uicache' option in level 2 So that users do not get prompted with this. Follow-up on c34590161082.

[server] Add a "scheduler" command to run repository scheduler This commands starts the repository scheduler as a standalone process that should complement a CubicWeb web instance running as a WSGI application. Added a log message in repository's shutdown method to help testing the command (i.e. make sure the method is called after the scheduler stopped). Related to #17057223.

[cwconfig] Do not instantiate a repo with a scheduler in repository method None of the caller of this method need the repository to have a scheduler and having a scheduler should be something that's explicitly requested.

[server] Make cubicweb/server/utils.py flake8-clean

[server] Drop utils's LoopTask and TasksManager classes not used anymore Related to 17057223.

[server] replace repository's tasks manager by a scheduler Repository() does not accept anymore a 'tasks_manager' argument but rather a 'scheduler' argument which is expected to be an instance of sched.scheduler class. The drop the _tasks_manager attribute of the repository and adjust all internal usages of it. In particular, in the 'repo_stats' service we do not export 'looping_tasks' statistics anymore as there's no way to retrieve this anymore from a web instance. Closes #17057223.

[server] introduce a scheduler class to run repository "looping tasks" We just use the sched module from the standard library and introduce a tiny Python2/3 compatibility layer (more for convenience actually). The "looping" aspect of tasks (previously in LoopTask class) is re-implemeted as a `schedule_periodic_task` function. This is a reasonably thin layer as compared to LoopTask/TasksManager classes. Only the "restart" aspect of LoopTask is no longer present as I'm not sure it's worth keeping. The advantage of using this (in addition to eventually dropping our custom code) is that this scheduler class provides a `run` method that blocks the process while running tasks in its queue. So we can rely on this to have a 'scheduler' ctl command (see forthcoming patch) that would only run "looping tasks" without having to implement the "blocking" aspect ourself. Related to #17057223.

web: add options to ignore css compilation and uicache

[skeleton] call includeme from new cube

[etwist] Do not call repository's start_looping_tasks anymore and warn about this We are about to drop this method from Repository class and replace it by a blocking alternative. This is not compatible with how things currently work in a Twisted server implementation. So do not start repository "looping tasks" in Twisted server anymore and issue a warning about this. If someone is interested in restoring the "all-in-one" behavior where the repository runs within a Twisted server, they may start by implementing repository looping tasks using a Twisted mechanism such as, e.g., http://twistedmatrix.com/documents/current/core/howto/time.html and eventually provide the repository with a compatible scheduler instance so that is can register its periodic tasks. At the moment, we lack resources to do this (and maintain the Twisted server of CubicWeb in general). Related to #17057223.

[test] Flake8-clean and use stdlib unittest in cubicweb/server/test/unittest_utils.py

[web] Don't raise ProcessFormError if there is no value specified a03376213747 introduced a slight modification in None / empty string values and with it a regression where an exception is raised on empty values, while we should simply consider no value is specified and return None.

[test] Cleanup imports in unittest_form Remove unused and reorder, + use bare unittest along the way.

Fix log level parameter not taken into account in cwsource log table An error in the jquery selector of the html widget controlling the log level was the cause of this bug. Closes #15772634 (grafted from c9129aae884b476455c8ed1ad802efc3a26503a5)

[pyramid] Drop call to repository's start_looping_tasks method and warn about this We are about to drop the start_looping_tasks method and running "looping tasks" along the WSGI application is not a very good idea. So issue a warning pointing to the forthcoming "scheduler" command. Related to #17057223.

[test] Make unittest_serverctl.py flake8-clean

[wsgi] Drop calls to repo.start_looping_tasks It's unlikely that these implementations were ever used so we do not bother with deprecation or a warning. We just drop the call to this method which should not be called from within a WSGI application. Related to #17057223.

[pyramid] Drop useless "init_instance" module

[server] Drop inexistent "bootstrap" argument in Repository initialization This is a missing bit from 5de78b6fff2e. Unfortunately this code appears to be uncovered by our test suite.

[server] fix a typo in a docstring

[ctl] Load available configurations in "cubicweb-ctl list" Otherwise we rely on associated ctl plugins to be loaded which is arguably orthogonal to configurations.

[web/views] Fix a docstring

[server] Use looping_task method in Repository._prepare_startup()

[skeleton] Drop logging configuration from development.ini This is actually not useful as logging is already initialized and configure "somewhere else" where the repository is started.

[pyramid] Drop retrieval of auth/session secret in all-in-one.conf We actually never supported this in cubicweb, but only in pyramid-cubicweb.

[cwctl] Recommend 'pyramid' before 'wsgi' when twisted is not available Not sure anyone ever really used the latter and the former is certainly more reliable/tested.

[cwctl] Drop message about 'the pyramid cube' in "start" command This is shown when twisted is not importable and we suggest to use 'cubicweb pyramid <appid>' instead. Since 3.24, cubicweb-pyramid got merge in cubicweb so drop this reference in the message.

[cwconfig] Fix two NameError in load_available_configs() This comes from a copy-paste in d92d75b17a85.

[etwist] Drop try/except around definitions of 'all-in-one' configuration and command handlers cubicweb.server is no longer conditionally shipped, neither in python package nor in debian package since 3.24.

[server] Call 'server_startup' hooks at the end of repository "bootstrap" Now that we have guarded all calls to Repository.looping_task() in 'server_startup' hooks we can execute this hooks category at bootstrap step. This way, repositories running without a tasks manager (i.e. those embedded into a WSGI application) will have these hooks triggered.

[pyramid] Drop module-level cache and cleanup looping tasks in tools And use a LRU cache over cached_build_user function. This looping task is problematic because it would not be run from within a WSGI application which does not have a repository with a tasks manager. This pulls an explicit dependency on 'repoze.lru' but it's not a big deal since pyramid already depends on this. RPM spec file not update since it does not even mention pyramid...

[hooks] Return early in server_startup hooks if the repository has not tasks manager

[server] Only register "clean_sessions" looping tasks if repository has a tasks manager This prepares for calling Repository's _prepare_startup() in bootstrap() so that repository instances without a tasks manager running can still have their 'server_startup' hooks triggered (this is particularly useful for BFSS storages).

[utils] Do not pass a tasks manager to Repository in admincnx() We do not call repo.start_looping_tasks() for the instantiated repository, so a tasks manager is useless.

[server] Separate repository bootstrap from initialization Thus we now call 'bootstrap' here and there explicitly and remove call of this method in Repository.__init__(). This way instantiation of a Repository does not *implicitly* triggers the "bootstrap" step, which is arguably not a trivial thing and thus deserves to be independent. In __init__, set 'shutting_down' attribute to None and then to False in bootstrap as a mean to indicate that, when initialized, a repository is neither shutting down nor started (not sure where this is used though).

[server] Also remove tmpdir in case of error during restore database command

[server] Rename Repository's init_cnxset_pool method bootstrap See the (removed) docstring for a rationale...

[server] Replace server config's init_cnxset_pool attribute by a "bootstrap" parameter in Repository This 'init_cnxset_pool' class attribute is actually used to control whether a Repository instance should be "bootstraped" (see Repository.init_cnxset_pool() for a definition of "bootstrap") or not. I seems clearer to me to have this controlled by a boolean "bootstrap" initialization parameter in Repository.

[server] Drop close/open steps in NativeSQLSource.restore() The only place where this is called is in ServerMigrationHelper.restore_database() where config.init_cnxset_pool is set to False. So these steps appear to be useless.

[skel] Fix rpm's .spec file skeleton It's broken for new-style packages since it doesn't consider (even remove) python packages.

[server] Move "starting repository..." message where this actually happens

[server] Initialize Repository without a tasks manager in ServerMigrationHelper.restore_database() We don't need a tasks manager here I think. Thus instantiate the Repository from its class directly instead of using config.repository() which set a tasks manager.

[server] Fix a typo in log message in Repository.init_cnxset_pool()

[cwconfig] Issue a warning if a configuration module cannot be loaded We already do this when loading ctl plugin modules, so make things symmetrical for config modules.

[ctl] Load available configurations in "cubicweb-ctl list" Otherwise we rely on associated ctl plugins to be loaded which is arguably orthogonal to configurations.

[skeleton] Set cubicweb.bwcompat to False in development.ini Quite a few things from the default web UI do not work when running the application through pserve (in particular, data files are not apparently served). So better disable the "bwcompat" mode until we are sure it works properly (or it gets dropped ;)).

[pyramid] Use existing repo in PyramidCWTest We thus do not make use of config_from_cwconfig() and build the configurator instance by hand prior to include 'cubicweb.pyramid'.

[pyramid] Make it possible to setup CubicWeb instance from an existing repo in includeme()

[pyramid] Move loading of pyramid_debugtoolbar later in includeme() To gather cwconfig and repository instantiations.

[skeleton,pyramid] Move pyramid app definition in cubicweb.pyramid module The application definition is actually not specific to the final "cube" being bootstrapped from skeleton. This patch thus move the pyramid application function into cubicweb.pyramid module and let cubicweb register the "paste.app_factory" entry point (instead of the bootstrapped cube). Useless call to `config.scan` is dropped along the way.

[pyramid] Add a copyright and docstring to all modules We add copyright statements for both UNLISH (original author) and LOGILAB.

[cwconfig] Strip "cubicweb_" prefix from cube name in available_cubes() Closes #17054738.

[web] fix os.rename usage on windows when destination exists os.rename on windows will raise OSError (or WindowsError subclass) when if destination file already exists. Also check that exception is EEXIST. There is an attempt to fix in f6ba947c but using IOError instead of OSError. Closes #14214794

[web/views] show composite entities in delete view Disabled by default, can be activated with show_composite = True Display first level of composite entities in a treeview, limited to the current (page_size - 1), so the maximum of displayed entities bump to page_size * (page_size - 1).

[workflow] Utilities for declarative definition of workflows Closes #5337897

[server] Remove pseudo-handling of exceptions in Repository._delete_cascade_multi() It seems to me that we never want to pass on an exception here be it in "test" mode or not, so remove the last `except Exception:` clause. For instance, the actual implementation would pass on an IntegrityError and thus possibly hide it in a log message. Concerning the `except Unauthorized:`, as said by the log message this should not happen because we are within a `security_enabled(write=False)` context. So remove it as well. As far as I can tell, this strange handling of exceptions dates from 37668bf302f5 and there is no clear justification to it.

[web] fix os.rename usage on windows when destination exists os.rename on windows will raise OSError (or WindowsError subclass) when if destination file already exists. Also check that exception is EEXIST. There is an attempt to fix in f6ba947c but using IOError instead of OSError. Closes #14214794

[skeleton] Add "cubicweb.session.secret" to development.ini Commented as other "secret" settings. At least, now all settings are present in the development.ini file. [ci skip]

[pyramid] Include 'cubicweb.pyramid.predicates' where it is used It's only used in "rest_api" module.

[pyramid] Rename make_cubicweb_application function as config_from_cwconfig And update its docstring. This function does not actually "make a cubicweb application", it just builds a pyramid.config.Configurator instance from a CubicWeb config object.

[server] Reprase messages of db-check to avoid using "system" and "sources" And rather mention "entity type table" and "entities" table, which are clearer references.

[predicates] Fix reference to has_related_entities in partial_has_related_entities docstring

Fix possible double import of cubes modules When cubes using the new layout are imported with 'cubicweb_<cube>' and with 'cubes.<cube>', the same module is imported twice. Handle this by adding 'cubes.<cube>' to sys.modules when importing from 'cubicweb_<cube>'. Move load_module() to a sub class _CubesLoader to share informations computed in find_modules(). Don't handle subpackages in _CubesImporter and rely on normal import machinery instead. Add a test and use unittest from cubicweb.devtools.testlib which resolve to unittest2 on PY2 with assertLogs() method.

Make load_module() return existing module if present in sys.modules Otherwise the reload() builtin will not work correctly: https://www.python.org/dev/peps/pep-0302/#specification-part-1-the-importer-protocol
