[rqlrewrite] Enhance detection of need for Exists node We actually want one only if this is not a (`And` / `Or`) binary tree of `Not` or `Exists` nodes, so write a recursive function to tell so. Related to #17074119

[rqlrewrite] Fix rewrite on ambiguities introduced by NOT relation or "is IN" type restriction When some inserted RQL snippet generate more solutions than the original RQL, the rewriter attempt to duplicate the snippet for each newly introduced solution. There are though some cases where we do not want this behaviour in case of ambiguities introduced by: * NOT(X relation Y) expression, since it won't be equivalent to NOT(X relation Y1, Y1 is Type1) OR NOT(X relation Y2, Y2 is Type2) ; * EXISTS(X relation Y, Y is IN (Type1, Type2) expression, since it's not actually necessary to split an explicitly introduced ambiguity (and it crash if we attempt to do so, so...). In test, we've to modify the `rewrite()` function because in the newly introduced test we need the same constraint to be applied to two variables in the original query, and this was not supported before. Notice the generated RQL in test is still *NOT CORRECT* "(EXISTS(NOT EXISTS() OR EXISTS(...))", or at least isn't optimal. This will be fixed in a forthcoming changeset. Related to #17074119

[dataimport] Add explanation about why external entities can't be inserted By default after the import processed the importer indicates which external entities can't be inserted because they are missing dependency data (other entities, used in inlined or mandatory relations). It usually helps there to find out which extids / relations are missing, so add this to the log.

[querier] Fix typo in Unauthorized message exception

[massive store] Ensure temporary metadata table get dropped even if there is some integrity errors while inserting entity values or setting back index/constraints, or any other errors. In case of exception, rollback to ensure we're not committing undesired intermediate state.

[test] Stop using lgc.testlib.unittest_main in dataimport's test_sqlgenstore.py

[test/cleanup] Cleanup flake8 errors in dataimport's test_sqlgenstore

[pkg] Fix path error in flake8-ok-files 'sources' is a subpackage of 'server'.

[cleanup] Fix undetected pep8 error

[doc] Set release date of 3.25 in changelog

[cwconfig] load appobjects subpackages recursively This is a regression appeared in 3.25.0. Appobjects (entities, views etc) subpackages should be loaded recursively, this is the historical behavior, relevant code is in logilab.common.registry._toload_info(). To keep historical behavior schema subpackages should not be loaded, relevant code is in yams.reader.get_schema_files(). We may want to have a consistent behavior later on... Closes #17073706.

[pkg] Set version to 3.26.0.dev0

Merge with 3.25 branch

Added tag 3.25.0, debian/3.25.0-1, centos/3.25.0-1 for changeset dacc5b168e29

[pkg] Version 3.25.0

[entities] Fix backward compat of IDublinCore adapter wrt dc_long_title `entity.dc_long_title()` used to fallback to `dc_title()`, and most entity types were relying on this, thus only implementing the later. Since introduction of the IDublinCore adapter, if one call `entity.dc_long_title()` on an entity that only implements `dc_title()`, it will retrieve the adapter which will then call its own `title()` method instead of the `dc_title()` method of the entity as expected. Fix this by calling instead `entity.dc_title()` which will eventually kick in the backward compat layer if necessary.

[web] Do not try to rmtree symlinks in rmtreecontent() There is a symlink in data directory (created by generate_static_dir() method) and trying to rmtree() it will fail with an OSError. So we unlink() it instead.

[pkg] Version 3.25.0rc3

[test] Stop using lgc.testlib

Fix some flake8 errors

[sources] Turn classmethod into standard method No need for a class method and easier to get proper logger including source's name.

[test] Add some tests for hooks.syncsources for parts which are not located in some source's check_config / check_urls method.

[sources] Check source's url attribute value on creation/modification Similarly as for config. Now, ldap source validation is properly done there instead of at initialization time.

[sources] Check sources configuration is fine on creation/modification Reintroduce usage of 'source.check_config' which had almost disappeared, as well as tests for the currently detected errors. Part of the system source specific checking done in syncsources reimplemented in a specific check_config implementation. Tests are dispatched among ldap / datafeed and syncsources tests but are not strictly correctly located (notably syncsources tests behaviour of the native source's check_config). The system source url checking part which disappears from syncsources will be reintroduced in a follow-up.

[test] Fix option name in ldap wrong group test which wasn't actually testing what it expected (and nothing guarantee it does now, but that's another story). Fixing this will avoid failure once we properly check the configuration.

[sources] Enhance prototype of check_conf_dict * mark it private * explicit name * update docstring Private function is still called from syncsources but this will be updated in a follow-up.

[sources] Stop translating validation error this should be done later in the web ui, where lang is properly set.

[sources] Simplify source's init method Only call it when enabled instead of giving a boolean flag indicating whether it is or not (which were not correctly considered).

[server] Deprecate Repository.sources_by_eid It's not used anymore within cubicweb itself.

[server] Add source_by_eid and source_by_uri methods to repository Most of the times we only need to retrieve one source (either by uri or eid) and querying sources_by_eid and sources_by_uri properties on repository just for one item is costly. So these methods query what's needed. We issue a ValueError (instead of KeyError for sources_by_{eid,uri} dict) in case the key is not found.

[hooks] Remove list() around repo.sources_by_uri There's no need to convert it as a list anymore since sources_by_uri is a property and will not be modified.

[server] Inline _entity_update method into init method of AbstractSource This _entity_update method does not make sense now that we do not update source from database information but always build them afresh.

[server] Drop update_config method of source It does not make sense anymore to update the config of a source instance (subclass of cubicweb.server.sources.AbstractSource) now that they are always built from database information (CWSource). In datafeed and ldapfeed, we move all code from "update_config" method in "init" method. This changeset fixes LDAPFeedUserDeletionTC.test_a_filter_inactivate() failure (unittest_ldapsource.py) introduces in previous changeset.

[server] Make "sources_by_uri" and "sources_by_eid" properties of repository I.e. do not populate these dict as repo initialization (bootstrap step) but always use information from database. This is needed because when multiple instances of the same application run, if one instance adds a CWSource the other ones will not see it. In particular, when using a scheduler instance, new CWSource will be added by the web instance and not seen by the scheduler which is supposed to update them. We thus define properties for sources_by_eid and sources_by_uri instead attributes on repository instance. CWSource entities are thus retrieved from database every time these properties are accessed. We factor out initialization of the "source" instance (subclass of cubicweb.server.source.AbstractSource) in a _sources() method. Note that this method takes care of calling "init" method on the source as well as "set_schema" (previously done in repo.set_schema(), which now only touches system_source). Accordingly the "init_sources_from_database" method is dropped along with "add_source"/"remove_source" methods. In syncsources hook, we thus drop: * SourceAddedOp operation which called repo.add_source() so that the SourceAddedHook only cares about checking source configuration now; * SourceRemovedOp and SourceRenamedOp operations for the same reason; * SourceConfigUpdatedOp as updating the live config of source is meaningless once we rely on them being retrieved from the database; * SourceHostConfigUpdatedHook hook which is now useless without call to SourceConfigUpdatedOp; In 3.10 migration script, remove usage of sources_by_uri repo attribute which, unless I'm missing something, appears useless (at least now). In tests: * unittest_datafeed: remove test_update_url method since we dropped respective hook; * unittest_ldapsource: LDAPFeedUserDeletionTC.test_a_filter_inactivate() currently fails because it still relies on live config being updated, this will be fixed in the next changeset once all "live source" logic will be removed.

Add a "Contributing" section to README with patch submission guidelines For the CubicWeb project and its dependencies, we now prefer patches submission and review by email on a public mailing list. We are thus moving away from the previous vcreview-based workflow taking place on the forge. This change is motivated by the following points: - the current reviewer assignment mechanism (pick a random reviewer, rely on reviewer availability rather than on willingness to review, send related patches to distinct people, etc.) is inefficient if not counter-productive; - most of the times, discussion only happens between the patch submitter and a reviewer with no easy way to increase the audience; - cubicweb-vcreview has no concept of patch series; - cubicweb-vcreview is not actively maintained anymore and its usability keeps deteriorating. We expect that email-based submission and review of patches will circumvent these limitations. Anybody interested in the project is welcome to subscribed to the mailing list and participate to the review process. This patch documents the basic workflow of patches submissions by email.

[cwctl] do only clean static data dir content (closes #17069762) deleting the directory itself is useless and may be a problem in automated deployment environments (user may not have permissions to delete or create that directory).

[cwctl] add a no-config-update option to the upgrade command (closes #17069607)

[cwconfig] Add "pyramid" config type to MCOMPAT dict I don't know what this is for exactly, but the accept_mode method below queries this dict with the configuration type name. And if the latter is "pyramid", it crashes since there's no key in MCOMPAT dict. So add one with the same value as "all-in-one". This code is called during "upgrade" migration in particular.

[pyramid] Avoid shutting down the repository at exit if it's already shutting down For install `cubicweb-ctl pyramid` command will explicitly call `repo.shutdown()` so the atexit hook is redundant. Prevent the latter to be executed when the repository is already shutting down (otherwise one gets an assertion error).

[server/test] Extract a "ldapsource" function in unittest_ldapsource.py We will add more use of this pattern in forthcoming changesets, so avoid repetition.

[server] Move "system" source initialization into its own method

[entities] Make CWSource's dictconfig method clearer

[entities] Move CWSource update_config method as a function in 3.15 migration script This script is the only caller of this method. In the code of the function, drop "skip_unknown" argument and continue accordingly upon OptionError.

[server/test] Turn "pull" method of LDAPFeedTestBase into a staticmethod Because it does not use reference to "self" (which should be "cls" for classmethod).

[py3] Use six.text_type instead of unicode in _CWSourceCfgMixIn.update_config()

[server] Drop condition on "3.10" migration in repo.init_sources_from_database() We'll duplicate the code of this method in forthcoming changeset so clean it up a bit of old stuff.

[pkg] Version 3.25.0rc2

[doc] More release note about session data handling mentionning deprecation of _cw.data and removal of get/set_shared_data.

[session] Drop long deprecated [get/set]_shared_data methods they are deprecated since 3.19 and access to the .data attribute itself deprecated in 3.25, so it's time to drop them.

[session] Drop the user session synchronization machinery which should not be necessary anymore since groups and properties are fetched for each request (cache lives in transaction_data).

[session] Avoid deprecation warning on access to Connection.data this attribute has been deprecated during the session related rework, remove warning by explicitly storing data in .transaction_data since session data is not anymore reachable through Connection object. This will allows simplification of session synchronization hooks in a later cset. Also since we do not rely anymore on session data here, we may at some point rewrite those properties to rely on the ORM instead of such custom caching.

[doc] Add release note about change in uicfg

merge 3.25 heads

[hg] Add generated slapd.conf to hgignore

Fix flake8 errors in unittest_cwctl

[cwctl] Drop 'cubicweb_' prefix when displaying cubes with 'cubicweb-ctl list' consistently with newcube / create commands. This is an alternate implementation to backed out changeset fe995d56c949. Closes #17054738

Fix flake8 errors in unittest_cwconfig

[config] Test loading of ccplugin modules to ensure ccplugin modules of cube as package aren't loaded twice, once as `cubicweb_<cube>.ccplugin`, once as `cubes.<cube>.ccplugin`. This test used to fail until fe995d56c949 has been backout. It requires calling `cleanup_sys_module` in `CubicWebConfigurationTC.tearDown` to remove any cube's submodule loaded during tests, so content of `sys.modules` may be tested.

[test] Extract out method-which-is-not-a-method mocking iter_entry_points to ease reuse and improve readability.

[cwconfig] Add a docstring on available_cubes method a renaming could be better at some point, but that's a start.

Backed out changeset fe995d56c949 available_cubes should not strip cubicweb_prefix but return actual package name for cube as package, since its output is also used to e.g. get ccplugin or site_cubicweb module name. Original aim of this set was to fix output of the "cubicweb-ctl list" command. This will be done by an alternate implementation in a later cset.

[hooks] Drop "logstats" hook It is now useless as its looping task would not run on a web instance because respective repository has no scheduler.

[hooks] Do not register "logstats" if repository has no scheduler

[server] Introduce an `has_scheduler` method on Repository This is to be used by client application to determine if looping tasks may be registered in the current process. By checking this, one will avoid the warning in looping_task method when the repository has no scheduler.

[server] Warn instead of failing when a looping task is registered and repo has no scheduler We should provide a way for client code to detect if they should register the looping task or not. See next patch for that.

[server] Exit quickly when a looping task is registered in maintenance mode In such cases the repository will not have a scheduler on purpose because the repository will not be kept running and will quickly shutdown after migration so that it's undesirable to have looping tasks being executed.

[config] Drop unused init_available_cubes method

[doc] Move content of former README.pyramid into relevant modules

Drop README.pyramid.rst file It has been kept since 3.24 when we merged pyramid-cubicweb and cubicweb-pyramid repositories into cubicweb's one waiting for someone to move the information in some canonical place but this never happened and this information is probably not so useful or already existing elsewhere. So just drop the file.

Make entypo link a true URL in README

Refer to cubicweb.readthedocs.io in README docs.cubicweb.org contains outdated documentation at the moment (and for quite some time); until it gets update, refer to the up-to-date documentation on readthedocs.

[server] don't catch exception from postcommit_event() if we are in test mode The historic behavior is to hide potential exception occurring in postcommit_event(). Unfortunately logging statements are hidden by default during tests and it become very hard to debug. At least raise if we are in test mode.

[pkg] Version 3.25.0rc1

[tox] Simplify command line to build the doc

[pyramid] Drop warning about pyramid_debugtoolbar not found in debug mode Some people way want to run a pyramid server in debug mode without the toolbar. This warning is annoying for them. Others should just install and *include* the toolbar by hand.

[pkg] Add development.ini.tmpl to "cubicweb.pyramid" package data Otherwise the file is not installed and `cubicweb-ctl create -c pyramid` does not work.

[skeleton] Don't use system site packages in tox environment As we changed this in cubicweb, there is a consensus that this is not the best practice so let us change it as well for skeleton.

[doc] Update "settings" pyramid documentation Document that without "bwcompat" we can use a development.ini file directly and add a dedicated section to list configuration options.

[doc] Update the "quickstart" page of pyramid documentation Again mentioning the two modes of operations and dropping references to prior implementation.

[doc] Rewrite "pyramid" index page in the book We drop references to pyramid-cubicweb and cubicweb-pyramid, remaining of the merge in 3.24. We now mention the two possible operation modes (with bwcompat being true or false).

[doc] Drop documentation for cubicweb.pyramid.tools module Which, as documented, mostly consists of internals.

[doc] Drop reference to "make_cubicweb_application" in pyramid doc This function got renamed into config_from_cwconfig and this is arguably an internal detail so should not appear in the API documentation.

[doc] Remove trailing whitespaces in doc/book/pyramid/index.rst

[tox] Install "pyramid" dependencies in "doc" environment Otherwise most of the cubicweb.pyramid API doc fails to build. For this we skip installation in the "doc" environment and source the new requirements/doc.txt which will install cubicweb[pyramid], thus pulling cubicweb plus pyramid's dependencies. Furthermore this requirements/doc.txt would be useful to build to documentation on readthedocs.

[web/views] fix bad html in deleteconf with show_composite=True On an entity with no composite an additional item "None" was displayed.

[web/views] display unique composite entities in deleteconf When the entity has two relations to the same composite, display it only once.

Really make rqlrewrite flake8 compliant

[pyramid] disable bwcompat by default in PyramidCWTest To avoid cubicweb exceptions handling.

Fix flake8 errors in rqlrewrite.py

[rqlrewrite/schema] Avoid parsing computed relations for each query The RQLRelationRewriter is instanciated for each RQL query, it should avoid parsing computed relations formula by using a cache, which seems rightly located on the instance's schema. This brings a *huge* performance boost to some pages on application with a few computed relations (x4 observed on a client app). Kudos to Adrien, David and Sylvain. Closes #17059828

[pkg] Restrict yams version to be less than 0.45.0 This is a backport of 10d3bf220be2 on 3.23 branch

[pyramid] Remove pyramid_debugtoolbar from "pyramid.includes" Most of the times, the package is not installed (not pulled by cubicweb[pyramid] nor pyramid itself) in a fresh environment so that first start of a new instance will fail.

[doc] Add some details about rtag derivation and server api cleanup in release notes

[doc] Simplify release notes section Those are all about backward incompatibilities, keep only one section about that.

[doc] Fill release notes for 3.25

[devtools] Create "newcube" in current directory by default Instead of using "cubes path", which in many cases will be something wrong (like <prefix>/share/cubicweb/cubes) now that cubes are regular Python packages.

[pyramid] Do not register repository.shutdown atexit in test mode It seems that there already is a special shutdown step for repository in test mode and pyramid's atexit handler interferes with it leading to assertion error about 'shutting_down' attribute being True in Repository.shutdown().

[cwconfig] don't rely on _CubeImporter while loading cubes _CubeImporter can load cube subpackages twice (there is a test for submodules in cubicweb.test.unittest_cubes.test_no_double_import() but not with a subpackage). Since _CubeImporter is for backward compatibility and is supposed to be deprecated as soon as possible, don't rely on it when loading cube schema or appobjects and always load the real modname (eg. cubicweb_<cube> if exists else cubes.<cube>).

Added tag 3.24.7, debian/3.24.7-1, centos/3.24.7-1 for changeset 58f1e8545a77

[pkg] Version 3.24.7

[pkg] Restrict yams version to be less than 0.45.0 Because of reader's API changes x and other subtle but hard to debug changes in appobjects registration in version 0.45.0. Closes #17065626.

[pkg] Version 3.25.0rc0 Let's make a release candidate version of CubicWeb 3.25.0 (only for the Python package), in the hope that some issues that we usually discover after release will be sorted out before.

[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).

[pkg] Depends on yams >= 0.45.0

[pkg] Depends on logilab-common >= 1.4.0

Merge with 3.24 branch

Added tag 3.24.6, debian/3.24.6-1, centos/3.24.6-1 for changeset 4029fb83a67d

[pkg] Version 3.24.6

Merge public heads

[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.
