[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.

[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.
