[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.

[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

[server] Ignore computed relations in "relations" integrity checker

[server] Use global registry variable of integrity checker functions Instead of querying globals() in checkintegrity.check(), we maintain a _CHECKERS dict mapping checker name to function in checkintegrity module. This is later used to build the list of available checkers in 'db-check' command help.

[doc] Add 3.25 release notes [ci skip]

[repository] possibility to disable connections pooling Add a new configuration option 'connections-pooler-enabled' (default yes). If set to no, disable connection pooling and open new connections to the database on demand. This allow to use CubicWeb with other poolers (such as pgbouncer).

[js] Fix loading image URL

[migration] Move pyramid-related migration after "entities" table modifications Otherwise, we getting into `add_entity_type('CWSession')` we try to insert a CWEType without any 'asource' column (per 3.24's schema) whereas the backend still wants it. Closes #17054035.

Merge 3.24.5 into default branch

[entities] Introduce an IDublinCore adapter Move all dc_ methods from AnyEntity to the new IDublinCore adapter and proxy them through a __getattr__ method on AnyEntity. Current test suite should be enough. Closes #3119992.

[skeleton] Add an entry point and configuration for running a Pyramid application We add a `pyramid_main` function in __init__.py that instantiate the WSGI application using "cubicweb.pyramid"; this is defined as an entry point (in setup.py) so that pserve_ can find it. Alongside comes a development.ini file which includes basic settings so that running a Pyramid+CubicWeb application works (only the "instance=<appid>" may be passed as a command-line argument). Logging is also configured there, but only includes the cube at stake and cubicweb (others could be added if needed). .. _perse: \ http://docs.pylonsproject.org/projects/pyramid/en/1.8-branch/pscripts/pserve.html

[cwconfig] Issue a warning when a "core" ctl plugin failed to load This is often because of a missing dependency, the warning would indicate this hopefully.

[devtools] Skip computed relations when attempting to auto-populate test database Fix the automatic database population underlying automatic test to avoid attempt to create computed relations.

[test] Use our BaseTestCase in unittest_rtags.py We need it DeprecatedInstanceWithoutModule for assertWarns method. Use this instead of unittest2 directly with a try/except block to get rid of flake8 error about import not being one top of file.

[server] Add a blank line before _CnxSetPool to fix PEP8 error

[pkg] Use logilab-common's master repository in dev requirements Should follow-up on 7b2247098f58 after integration on logilab-common side.

[rtags] pass module name to RegistrableInstance Instantiate a RegistrableInstance without passing the module name is deprecated in https://www.logilab.org/patch/10047069

[repository] move cnxset pool handling to a helper class The class has responsability to handle connections pool operations in a single public attribute 'cnxsets'. On Repository _get_cnxset() and _free_cnxset() are replaced by cnxsets.get() and cnxsets.release(). Drop multiple access to private attributes and methods from outside of Repository.

[pkg] Fix some error on building documentation

[source,native] Generalize the IntegrityError constraint parsing regex This allows catching constraint-related errors that have been translated by psycopg2, replacing surrounding english quotes by french quotes + space for instance. Closes #17047951.

[pyramid] use pyramid.request `path_info` property instead of `path` path is concatenation of SCRIPT_NAME and PATH_INFO we just need PATH_INFO here

[pyramid] fix login route with language-mode = url-prefix

[devtools] Make timeout error in qunit tests configurable and use SkipTest in test_jscript.py This is grafted from 87443f279b0f in default branch (got tired of CI failing because of these unreliable tests).

[web] Handle unspecified value in TZDatetimeField `field._ensure_correctly_typed(self, form, value)` should return None if value is None. Closes #17050181.

[web] Handle unspecified 'date' or 'time' in JQueryDateTimePicker.process_field_data() dict.get() may return None, which has no attribute strip.

[cwconfig] create a virtual "cubes" package _CubesImporter now handle import of "cubes" and return a virtual module so that "cubes" is always importable without having to create a __init__.py in CUBES_DIR and add CUBES_DIR/.. to sys.path. Drop custom code in setup.py used to create CUBES_DIR/__init__.py and drop now useless warning when cubicweb is installed in develop mode Update test_cubes_path() and ensure 'cubes.file' is not loaded before testing its import. This test seems to have mistakes because cubes are loaded automatically when discovering cw commands (cubes.<x>.ccplugin), not sure how this should be fixed definitely.

Change hooks control (deny_all_hooks_but / allow_all_hooks_but) to be more predictable Prior to this, if one execute code like: with cnx.hooks.deny_all_hooks_but('metadata'): with cnx.hooks.deny_all_hooks_but(): # mycode 'metadata' hooks will be activated anyway in the inner block, which is rather unexpected (of course in real life you only see the latest hooks control statement, the former being higher in the call stack). This is due to the underlying usage of old `enable_hook_categories` / `disable_hook_categories` methods, which were introduced much before the now official context manager based API (with `cnx.[deny|all]_all_hooks_but(...)`). To move on, this patch drop the two legacy methods, rename and privatize related internal state on the connection (`hooks_mode` becomes `_hooks_mode`, `disabled_hook_cats` and `enabled_hook_cats` become `_hooks_categories`) and reimplement the `_hooks_control` context manager to simply update them. See the added unit test for details.

[cwconfig] make appobjects_cubes_modnames() public The method is used in cubicweb.cwvreg without underscore and outside of the config class, so let's make this method public. Fix autoreload with twisted.

Fix str(Unauthorized) which is really problematic on python 3 where __unicode__ is never called anymore. This was caused because in PY3, CubicWebException.__str__ was referencing __unicode__ implementation of CubicWebException, not of its subclass that implements it. Fix a flake8 style warning about lambda assignment as a bonus.

[test] avoid using a deprecated feature of yams handle_file() now require a module name (yams@d9120d7)

[test] add some tests to web.views.baseviews

[tox] Drop "touch {envdir}/share/cubicweb/cubes/__init__.py" command on py34 env This was useful when we installed cubicweb in "develop" mode but we do not do this anymore.

Drop support for https-url in all-in-one.conf This feature allowing an instance to have both anonymous and authenticated (https) url is not used anymore, let's drop it.

[test] use TemporaryDirectory context manager For consistency with others tests, use TemporaryDirectory from cubicweb.devtools.testlib.

[tox] Drop "exclude" option from flake8 config and adjust flake8-ok-files.txt accordingly Some files listed in flake8-ok-files.txt were excluded of flake8 run because of the "exclude" option in tox.ini. Some of them were non-existent files (moved), some others were actually non-flake8-compliant. In the latter case, we adjust trivial errors (blank lines, module import not on top of file) but remove others (like cubicweb/test/unittest_utils.py) from flake8-ok-files.txt.

[autoform] Go through guess_field even when field class is specified using uicfg guess_field does not only find the proper field class for some attribute/relation, but also do some basic configuration depending on e.g. constraints. Before this patch, if one was specifying explicitly the field class using uicfg.autoform_field, this automatic configuration wasn't happening. Change form.field_by_name and ff.guess_field so explicit class are also automatically configured now. Closes #14474840

[uilib] Fix incorrect serialization of python dicts into javascript objects Valid javascript object keys must be surrounded by quotes unless they are valid javascript identifiers. Valid identifiers are a defined by complex and changing specs, so it is much simpler to always use quotes. Closes #17046704.

[repository] Fix connection-pool-size not set to 1 with quick_start enabled config.load_schema() and config.init_cube() reload configuration options from config file, so a manually set connections-pool-size (eg. when quick_start is enabled) wasn't working.

[migration] Enhance assertion message to get a chance to fix the problem

[migration] Skip virtual rtypes when adding relation definition through add_cube Virtual rtypes should be skipped as they are added dynamically on loading schema. Those are skipped by e.g. schema serialisation or add_entity_type, do the same thing here.

[migration] Avoid unnecessary intermediary commit when migrating a schema Those are low-hanging fruit following changes in ac74476d686c (Fix addition of entity type including boundary constraints on its own attributes): this is no more necesary to commit the get a new relation type definition in the schema. At some point we could/should probably do more on this topic to avoid intermediary commit on e.g. entity type addition, but this requires more work.

[migration] Fix addition of entity type including boundary constraints on its own attributes This was failing because of the sequence of sql executing when adding an attribute: 1. add entity type <commit> 2. add relation type for attribute 1 <commit> 3. add attribute 1 and associated constraints <commit> etc. In the case of e.g. start/end constraint, we were trying to add the constraint before addition of the constrained attribute (e.g. add constraint on 'start' referencing 'end', but only 'start' has been added yet, not 'end'). This patch fix this by: * adding the relation type to the schema without having to commit, but keeping the operation to revert the addition if necessary - this allows to a single commit for all attributes of the entity type ; * using a LateOperation on constraint operation, so we ensure attributes are actually added before any constraint is added.

[schema sync] Refactor AfterAddCWRTypeHook and AfterAddCWComputedRTypeHook so the latter inherit from the former and enhance their docstring.

Drop embed-allowed option, gone away for a long time

Never record undo information for session or data import for session, it may causes unlimited database size expansion while it makes no sense to undo this kind of changes. For data import, they are created programatically hence we may not want to undo this either.
