[devtools] Drop old init_test_database backward compat

[devtools] show DeprecationWarning during test execution They are not shown by default since python 2.7

[devtools] deprecate usage of sources file for test This is old support which clutters the code and should no more be used. As this is rarely used (if it is) and test only, it feels ok to drop support at once without a deprecation phase.

[devtools] Set dumb value for postgres's db-host to avoid unexpected connection to a local server Currently, if something goes wrong (eg config built before call to startpgcluster) while a pg server is running on localhost, it may connect to this server and run the test in there unexepectedly.

[ldapfeed] ldap3 do not raise an exception in case of failure of cnx.bind() but return 'False' instead.

[test] add a test to ensure we get an AuthenticationError with ldapfeed when using (correct login, wrong password) credentials

[entity] Exclude computed relations from Entity.copy_relations Closes #12481591.

[pkg] Set version to 3.22.2.dev0 So that cubes used in test dependencies do not install a released CubicWeb.

[devtools] pep8 a bit package's __init__

[test/server] Only use configcls with statement timeout when needed Other tests in PostgresFTITC class apparently do not make use of this particular configuration.

[server/test] Add an assertion in test_statement_timeout

[datafeed] minor cleanups to cwxml parser

[datafeed] don't allow arbitrary kwargs on DatafeedParser initializer else they will be handled nicely by appobject base class, while we rather want an error in the case of a source parser (arguable).

[datafeed] gives information about moved entities to the parser Also, don't support anymore arbitrary parameters at parser initialization. Related to #5414754

[datafeed] simplify SQL query used to retrieve information about entities from an external source no need to join on cw_source

[datafeed] rename parser.sourceuris to source_uris Its more readable. Also, uniformize related method and local identifier names.

[datafeed] move process_urls to the parser

[tox] Use py.test to run tests In unittest_rqlrewrite.py and repotest.py, rename utility functions so that they are not considered as "test functions" by py.test.

[test] Fix devtools unittest_i18n when ran without pytest There is currently some weird error, requiring both to hack cubicweb.__path__ and to stop using load_module_from_name to load the registry. Introduce a dependency on to-be-released version of logilab common integrating fix for https://www.logilab.org/ticket/6085650 Do some extra import cleanups along the way.

[server] explicitly set postgres LC_MESSAGES variable to C on connection We parse some error messages so we need them to be in English. It's not clear to me exactly when that's not the case, but this fixes running unittest_postgres' "test_constraint_validationerror" with py.test for Sylvain.

[web] cleanup xmlrss view Don't trigger exceptions unnecessarily, and add line breaks to the output.

[migration] add rollback when replace_eid_sequence_with_eid_numrange fails If we get here, the current transaction is aborted, so if we are to assume everything is fine and continue we need to rollback first.

[migration] move CWComputedRType later The ordering in this file is a mess, and things don't actually work this way (when upgrading from 3.17).

docstring fix

[cwctl] make cwctl not depends on cubicweb.wsgi (closes #12210063) cubicweb.wsgi may not be available at all on Debian.

[hooks/workflow] pass eids, not entities, from hooks to operations Passing entity objects around runs the risk of getting out of date data from caches.

[web/httpcache] fix Last-Modified generation time.mktime takes a time tuple in *local* time. We have an UTC datetime coming from the last_modified method, which we were interpreting as local time, leading to hilarity. Use calendar.timegm instead. Add tests for Last-Modified generation of the 'download' and 'manage' views.

[forms] Fix edition of TZDatetime attributes Parse the submitted web form values into a timezone-aware datetime (by default, UTC) when such an attribute is edited. This is done using an automatically-selected (by `web.formfield.guess_field`) field named `TZDatetimeField`. Closes #12666598.

[doc] fix abstract and example of data import

[doc] fix abstract of data import

[repository] drop remanescence of old multi-sources code we don't use anymore this inputmap/varmap thing.

Added tag 3.20.15, debian/3.20.15-1, centos/3.20.15-1 for changeset 636a83e65870

[pkg] 3.20.15

[views] do not eat the self._cw.message in LogFormView (closes #12421177) accessing self._cw.message now(?) eat the message, so don't call "self._cw.message" twice.

[server] make InternalManager.name() return an empty string (closes #12418708) Otherwise the notification emails sent via an internal_session never honor the EMAIL.sender-name configuration option.

[test/migractions] work around drop_cube not deleting final etypes Closes #10096736

[hooks] deleting a final entity type shouldn't try dropping an sql table

[tox] Use a revision on proper branch for Yams "default" is not good when some bug fix release suddenly comes out...

[webconfig] disable generate-staticdir by default Its side effects mean it can be inconvenient, and using it requires manual (web server) config changes anyway, so there's no reason it needs to be enabled by default.

[test] Skip test_deserialization_base (unittest_repository.SchemaDeserialTC) See ticket #10096736.

[devtools] drop unused DumbOrderedDict2 class

[devtools] fix sorting in ExecutionPlan._check_permissions on python3 Sort lists instead of dict_items objects to get predictable results. With this change, unittest_querier.UtilsTC.test_preprocess_security passes every time instead of once in a blue moon. Closes #11759133.

[test] assertItemsEqual → assertCountEqual in unittest_repository.py

merge 3.20.14 in 3.21 branch

Added tag 3.20.14, debian/3.20.14-1, centos/3.20.14-1 for changeset f66a4895759e

[pkg] 3.20.14

[tox] use master URL for yams repository No need to clone from review. This should help get consistent results.

[pylint] Avoid invalid-name on schema relation class names

[pylint] more work on the pylint support * uniformize usage of ClassDef and simplify related import * don't insert in the ast a python function but an astroid representation of that function * ignore __pkginfo__ file * drop attr-rgx, variable-rgx and argument-rgx, put the name in good-names instead * drop additional-builtins * add cell_call to the list of methods for which we don't want 'abstract-method'

[pylint] remove abstract-method warning This kind of message is targeted: "Method 'entity_call' is abstract in class 'EntityView' but is not overridden (abstract-method)" For now, only "entity_call" and "render_body" are dealt with, the list can be extended.

[pylint] upgrade pylintext plugin

update and enhance pylintrc

[schema] use json to serialize constraints Require yams 0.43: constraints are serialized to json, which means we need to recreate the actual checks in the database on upgrade. Temporary deps in tox.ini to pull respective changes in yams.

[pkg] fix cubicweb.spec syntax (grafted from 3309ddb970594cd54529f5c205d1ea5b5da4131e)

[pkg] Use Twisted < 16.0.0 We have some test failures with 16.0.0, such as: - test_put_content (unittest_server.ETwistHTTPTC) - test_base_url (unittest_httptest.TwistedCWAnonTC) (grafted from 10c12f31d0fe38c2e8814176fc42bf2ea210efdf)

[pkg] fix cubicweb.spec syntax

[cwconfig] Use imp.load_source instead of exec() to load site_cubicweb.py from apphome Lets us return a module object and go back to the previous code in CubicWebConfiguration._load_site_cubicweb.

[cwconfig] Stop using lgc.modutils to load *config.py and *ctl.py files

[cwconfig] Stop using lgc.modutils to load site_cubicweb.py files config.load_site_cubicweb function now takes a list of cubes (instead of paths) and default to all known cubes.

[test] Use a Popen in i18n tests Instead of check_call, so that we clearly see the failure. A bit of flake8 along the way.

[forms] Fix HTableFormRenderer _render_fields method behavior when display_label is False. Indeed, now the extra <tr><th>...</th></tr> are not inserted anymore unless display_label is True. Closes #3811325.

[connection] remove a dead counter Related to #1381328.

[session] drop .is_repo_in_memory This is deader than a dead dog's bone buried down a blind alley off a dead-end street in a ghost town. Related to #1381328.

[session] drop session-as-a-context-manager It made little sense in the 3.19 - session-as-cnx-bw-compat era, maybe. Related to #1381328.

[devtools/repotest] use the RepoAccess object Quite better than playing tricks with the Repo._sessions. Related to #1381328.

[devtools] adapt stresstester to current APIs

[session] retire session.vreg Related to #1381328.

[session] fix super call in Connection.__init__ The vile hacks in test fixtures are fixed.

[session,repo] remove last trace of "cnxprops" Related to #1381328.

[pkg] Use Twisted < 16.0.0 We have some test failures with 16.0.0, such as: - test_put_content (unittest_server.ETwistHTTPTC) - test_base_url (unittest_httptest.TwistedCWAnonTC)

[web/views] stop using cwaction='cancel' It's broken as of https://hg.logilab.org/master/cubicweb/rev/cb217b2b3

[test] fix test_printable_value_bytes with current pygments An empty span was added in https://bitbucket.org/birkenfeld/pygments-main/commits/164574c13533195a555181a2b9c685fea2470403

[session, repository] deprecate repo.connect and move .close reponsibility to session object Repository.new_session just returns a plain session object, and `.connect` (which returns a sessionid) is deprecated. For .close:: session.close() # done ! The session will bear the responsibility to call the "session_close" event but that's better than the previous idiom:: repo.close(session.sessionid) which involves both objects. Related to #1381328. Related to #2919309.

[web/test] fix typo in doc string

[web/httpcache] send weak ETags There's no way we can provide a strong validator in general (especially considering how ETags are generated by the current EtagHTTPCacheManager and EntityHTTPCacheManager). So mark our entity-tags as weak.

[server] print backend exception if we fail to execute an sql script It's more useful to see could not open extension control file "/usr/share/postgresql/9.4/extension/postgis.control": No such file or directory rather than merely -> ERROR, skipping /usr/share/cubicweb/cubes/postgis/schema/_ext.postgres.sql

[cwctl] drop unnecessary admincnx call from 'shell' The connection is done by the migration helper.

[serverctl] allow schema-diff when db and fs are not in sync

[cwctl] remove networked remote shell This was a dbapi leftover. Related to #3933480.

[web/calendar] fix regression in previous changeset "Enables css customization in CalendarView" was untested, and introduced a crash: TypeError: not all arguments converted during string formatting

Enables css customization in CalendarView now a custom css class can be set on the calendar div (closes #3654043).

refactor a bit breadcrumbs to ease overriding of the root's display

Add migration helper function to delete entity types faster Bypasses all hooks and (for now) ignores any composite relations.

[testlib] Import nocoverage from logilab.common.testlib This depends on a change in logilab-common 1.2.0

[web/test] replace unicode with six.text_type Some uses of unicode reappeared when merging changes from 3.19.14.

[devtools/testlib] Issue a RuntimeError when a generative tests is detected Otherwise, generative tests *à la logilab-common* in CubicWebTC test cases would silently not run (at least using logilab.common.pytest runner).

[devtools] stop using lgc.testlib.TestCase It's become incompatible with unittest(2).TestCase due to generative tests. Just keep the datadir/datapath and assertCountEqual bits in our BaseTestCase.

[test] Replace remaining generative tests by subtests

[tox] Enable all applicable py34 environments All except etwist. Comes with a few tricks in tox.ini: * add ``-e.`` to force installing of cubicweb in development because dependency cubes would otherwise install cubicweb 3.22 (the latest release), which is not python3 installable. * "install" cubes/__init__.py because the file is not installed in develop mode; maybe this file should be managed by cubes themselves...

[migration/3.10] fix AttributeError 'Connection' object has no attribute 'HOOKS_DENY_ALL'

[server/sources] Fix authenticate on pre-3.10 database When migrating from a pre-3.10 database, the CWSource entity type and cw_source relation type are not known, but authenticate should still work to be able to add them.

[test] Add a test ensuring new cube built from skeleton is flake8-compliant And make skeleton files actually flake8-compliant henceforth.

[skeleton] Ship a tox.ini file upon new cube

[web] fix headers on 304 responses (closes #11466875) The response MUST include the following header fields: [...] - ETag and/or Content-Location, if the header would have been sent in a 200 response to the same request https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5 Unfortunately we weren't copying headers from what would have been the 200 response, but from the request.

[web/httpcache] GMTOFFSET no longer exists

[web] fix headers on 304 responses (closes #11466875) The response MUST include the following header fields: [...] - ETag and/or Content-Location, if the header would have been sent in a 200 response to the same request https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5 Unfortunately we weren't copying headers from what would have been the 200 response, but from the request.

[rset] fix infinite recursion introduced in c1eb5a676c80 The mechanism to avoid loops in c1eb5a676c80 "[rset] Always complete attribute/relation caches in ResultSet.get_entity" breaks down: we would loop forever if two entities that were already in the cache were linked by a relation with ? or 1 cardinality in both directions. To avoid that, keep a set of already-considered columns. Related to #9942503.

pep8 unittest_application and unittest_formfields

[rset] Always complete attribute/relation caches in ResultSet.get_entity RQL queries are often designed to fill up the ORM's caches when fetching entities out of the result set. Until now, if an entry already existed in the entity cache, ResultSet.get_entity would return it unchanged, not using the new ResultSet's contents to update the attribute cache, breaking expectations (if the attributes are needed, they'd then be fetched later one at a time, one entity at a time), resulting in loads of DB accesses. So we change ResultSet.get_entity so that: * if the entity is already cached and has been instantiated from the same rset, it is returned as-is (to avoid loops) * if the entity is not yet cached, it is instantiated * if the entity is cached via another rset, its attribute/relation caches are completed Closes #9942503

[rset] refactoring of _build_entity method define a method for entity instantiation and storage in cache (related to #9942503)

[entity] comparing two entities returns NotImplemented Fixes a test when using some versions of unittest2, where assertItemsEqual tries a sort and expects TypeError, which it doesn't get if we directly raise NotImplementedError. The NotImplemented value is treated specially by the interpreter: https://docs.python.org/3.4/library/constants.html#NotImplemented

[test] replace one use of lgc.testlib.unittest_main with unittest.main

[test] stop using TestCase.set_description It's a lgc-ism.

[test] convert a lgc-style generative test into unittest2-style

[web/application] fix query log handling on python3 Writing bytes to a file opened in text mode doesn't work.

[devtools/test] duplicate CubicWebServerTC tests for CubicWebWsgiTC

[devtools/test] fix bytes vs text in test_base_url Needed for python3 with the next changeset

[devtools] skip CubicWebServerTC on python3 People should migrate to wsgi if they're going to use CubicWeb on python3.

[web/test] switch unittest_web from twisted to wsgi And make it pass on python3 while at it.

[devtools] add CubicWebWsgiTC Similar to CubicWebServerTC, except using wsgiref instead of twisted as an http server.

[web/test] return the hash of uploaded files in FileUploadTC instead of their contents json must be unicode, which doesn't go well with arbitrary file contents. Compute the file hash instead, as we know the hexdigest is (ascii) text.

[web/test] open() as a context manager

[web/test] json.loads expects text, not bytes

[wsgi] fix handling of multiple posted files We were only keeping the last received file.

[web/test] Reword doc string for fileupload ajaxfunc

[skeleton] do not import the __pkginfo__.py module to make cubes installable via setuptools When using a simple "import" statement, running 'python setup.py install' for a cube fails in a fresh virtualenv due to the fact the install of the dependencies (here cubicweb iteself) is done by the python process doing the cube's installation, so the __pkginfo__ module from the cube is already loaded (thus used) when installing cubicweb... So we apply the third technique from: https://packaging.python.org/en/latest/single_source_version.html

merge changes from 3.22.2

Added tag 3.22.2, debian/3.22.2-1, centos/3.22.2-1 for changeset 1b93ff37755b

[pkg] 3.22.2

[pkg] fix centos install

[datafeed] do NOT call commit in DataFeedXMLParser.process() (closes #10928592) and so, remove more useless code. Doing a commit in DataFeedXMLParser.process() is a bad idea because this method is called for every imported/updated entity, before handling deletions. So if we commit here, odds are quite high that we're violating some integrity constraint and end up with a ValidationError.

[schema] restore constraint checking when running on old sqlite Old sqlite3 doesn't provide CHECK constraint names in error messages, preventing us from translating a backend integrity error into a ValidationError. This was added in 2012, but the sqlite3 version in RHEL6 is older; so if we run on old sqlite, keep checking the constraints in python rather than only in SQL. Closes #10927494

[web/autoform] fix regression introduced by #5758ba784ebd The changes from cset 5758ba784ebd "[autoform] when building inlined-form view for a relation, consider related entities intead of other views" lead to an unexpected 'add new' link on creation of an entity with inlined form for a relation of cardinality 1. To avoid this, we should consider formviews and not existing relations when the entity is being created. Closes #10860258

[tox] Generate test environments for Python 2.7 and 3.4 Test commands for each environment are written down explicitly since I could not find a way to extract the "package" name (e.g. "hooks") from the environment name (e.g. "py34-hooks"). For Python 3.4 interpreter, only environments (subpackages) that do not depend on cubes for their tests are listed since those test dependency cubes are not yet installable with Python 3.x. etwist is also not included since the Python 3 port is not complete at the moment. From local testing, py34 tests pass for the following subpackages: - dataimport - entities - ext - hooks - wsgi

[notification] avoid using InternalManager when we've got a CWUser This will avoid potential information leak due to missed security restriction and is more compatible with legacy code (pb encountered in some client code). Closes #10294761

[dataimport] rename .time to .now attribute of meta generator

[pkg] Set version to 3.22.2.dev0 So that cubes used in test dependencies do not install a released CubicWeb.

[dataimport] cleanup a bit nohook store, mostly protecting some attributes

[dataimport] add a filter function to not fail if some extentity has several values for an attribute of final relation the function will simply record a warning in the import log and keep a value randomly. Notice the function has to be explicitly inserted in the transformation stream.

[sources] synchronize source asynchronously when started from the UI and redirect to the forthcoming import log, for a better user experience (there is still a lot more to do there though). Closes #10468967

[test] fix unittest_devctl on python3.4

[test] Make sure that newcube command test produces expected files

[server] remove some pre 3.10 compat Let's assume nobody will try upgrading an instance from pre-3.10 cubicweb to 3.23+. If they do, they're setting themselves up for a lot of pain anyway.

[pkg] use https URLs to pypi.{python.org,debian.net}

[migration] don't ask confirm for those sql queries

quick fix which closes #0673348 - see comment for more info

[migration] test if entity type has been in the deleted in the transaction should protect both clauses else we may attempt to execute the UPDATE query on a table which has been deleted. Closes #10692374

[pkg] 3.22.1

[cwctl] remove support for startorder file in /etc/cubicweb.d (closes #5618947) It's now useless.

[exceptions] fix string conversion for Unauthorized exception changeset 3cb87b61b067 changed CubicWebException to define __unicode__ as the main entry point for string conversion, but left Unauthorized's __str__ definition unchanged, leading to a mismatch. Closes #10646396.

Fix Binary on python < 2.7.4 (closes #10593811) Before the fix for http://bugs.python.org/issue10211 we can't pass a buffer object to BytesIO, so keep using StringIO in that case. And because StringIO is an old-style class, we can't use super().

[migration] fix crash on 3.22 upgrade if entity type doesn't exist in fsschema (pending removal)

[autoform] when building inlined-form view for a relation, consider related entities intead of other views by considering previous form-views, we may miss that there exists related entities but which are not editable. Closes #10495602

Add a __main__ to cubicweb This avoids calling cubicweb-ctl relatively in tests and could be useful in virtualenv. This is just a copy of bin/cubicweb-ctl file, which should probably be generated from a setuptools entry points.

merge 3.19 heads Getting an unexpected test error though: ERROR: test_edit_mandatory_inlined3_object (unittest_views_basecontrollers.EditControllerTC)

[cwvreg] Fix propertyvalues hot updates When CWProperty instances are touched, the corresponding value gets updated in vreg['propertyvalues'], but their type was ignored.

[pkg] remove useless python >= 3.4 dependency python is python2 is never >= 3.4.

[dataimport/test] fix test failures since 35b29f1eb37a The index name changed, so we need to follow suit.

[pkg] do not include toplevel directories in rpm (closes #10362119) Our spec file conflicts with the filesystem package in centos7: we set permissions to 0755 for /usr/bin and /usr/lib whereas filesystem sets them to 0555. So to be compatible with both centos7 and others we simply ignore these directories.

[devtools] fix config.repository signature Its argument is called 'vreg', not 'x'. Closes #10515113.

[predicates] fix paginated_rset when the class has no page_size_property Fixes test failure introduced by 70733b2dfd2a, which assumed paginated_rset would only be called on a class with a page_size_property attribute.

[repository] drop usage of no more necessary eschema_eid function since the previous cset, we are guaranteed that repository's entity schema will have their eid attribute properly set, so we don't have anymore to check everytime if some entity schema's .eid attributes is set or not (and retrieve it if not). Related to #10450092

[repository] set .eid on eschema when schema is loaded from the filesystem enforcing the contract that a repository's schema should have .eid attribute of entity schema set to the eid of the entity used to serialize them in the db. Before this cset, this was not true during tests or for some c-c commands where 'quick_start' is set (eg db-restore, i18ncube...). The change in server __init__ makes this assumption true during instance creation: the serializing code was actually setting eid on schema object, but a reference to a previously built schema was given instead of the one for the latest created repository. Closes #10450092

[dataimport] simplify SQLGenSourceWrapper.add_info At this point 'CWSource' is a thing (we're not in the middle of a migration), and source.eid won't be None (we read it from the db)

ensure .tox is blacklisted when recursing on the fs to get some files among others, avoid crash when using 'c-c i18ncube' on a cube using tox. Closes #10429317

drop a note about usage of sqls_create_multicol_unique_index and avoid a lgdb warning

[devtools] don't auto-populate virtual relations

[skeleton] Restore verbose output in setup.py This part of commit fdadf59be612 missing the integration window.

[hooks] Skip modification_date attribute in "notifentityupdated" hook Depending on the call order of hooks, "modification_date" may come in entity.cw_edited or not (from "metaattrsupdate" hook usually). It should however not be considered in the notification context. Closes #8842064.

[test] Gather tests about mail module From sobjects/test/unittest_notification.py to test/unittest_mail.py where other tests for mail.py are already. Some style fixes along the way.

[web/component] guard against invalid page_size form parameter Same as dff28956f37e, except the almost same code exists in two places (yay us).

[predicates] fix paginated_rset for components that change page_size_property The predicate and component had better agree on the page size.

[devtools] fix get_bounds Say an attribute has two IntervalBoundConstraints, one with minvalue=0 and the other with maxvalue=10 (not literally, or that could be a single constraint, but e.g. with references to other attributes). We don't want to override the minvalue of the former with None just because the latter happens last in the constraints list. This doesn't fix the case where two constraints both have a min or a max value. Meh.

[devtools] "fix" boundary condition for autofill maxvalue in an IntervalBoundConstraint is inclusive. If the min and max values happened to coincide, we would call random.choice on an empty list, which it didn't like. This is still broken in the case of BoundaryConstraint('>', minvalue), as we assume the minvalue is in the range, but that's something for another time.

[test] Use stdlib doctest module instead of logilab-common class The former just works fine now but the later does not play well with py.test.

[test] Re-implement generative tests with subtests

[devtools] Re-implement generative tests using subtests Generative tests as implemented in logilab.common.testib are not compatible with tests runner other than lgc.pytest and this implementation differs from the standard library, which has support for subtests_ since Python 3.4. Use unittest2 to bridge the gap. Maybe it'd be good to implement this on logilab.common.testlib side at some point. Let's see how this gets received here first. .. _subtests: https://docs.python.org/3/library/unittest.html#subtests
