[py3k] unicode → six.text_type

[server] Port BFSS to py3k The BFSS API changes in python 3: * 'defaultdir' MUST be a unicode object * 'fsencoding' MUST NOT be set In python 2, fsencoding handles both the encoding of file paths on the file system (utf-8 by default, but the system may actually be using something else) and the encoding of file paths that will be stored in the database. So in python 3, we wipe the slate clean: * rely on sys.getfilesystemencoding() to convert unicode objects to bytes * always encode paths to utf-8 for storage in the database Caveat emptor / here be dragons: * sys.getfilesystemencoding() depends on the current locale, which therefore MUST be set properly * when migrating an existing instance from py2 to py3, one MAY need to reencode file paths stored in the database

[migration] fix change_attribute_type to update the live schema Closes #7170830

[devtools] add has_cache for postgres (closes #5739624) devtools stores info about existing dbs in the db handler, but in the case of postgresql that doesn't take into account the path to the cluster's datadir. Which means if we run two test modules (in the same test run), we'll create a "__default_empty_db__" for the first one, cache its existence, and then when moving on to the other module, believe the template already exists (but since the datadir depends on the test module's path, it does not). This patch is a bit of a kludge, and it would be better to make the cache key include enough data to not need this, but I'm not sure how to do that.

fix bad-caching of datetime with tz info at sql generation time There is a special handling for datetime with tzinfo, where value was stored in the query cache. The implementation of merge_args was simply overwriting parameters of the query with those in the query cache, expecting no collision. To fix this: * handle replacement of tzinfo in merge_args, not at sql generation time * add an assertion to ensure we've actually no collision Closes #6978316

[autoform] fix appearance of link to add inlined creation form On entity creation, if there are some local permissions on the relation, we have no way of checking them since neither the subject nor the object of the relation exists yet. In such a case, we should add the link by default, for consistency (see other places where we use `may_have_permission`). Closes #6711900

[predicates] Simplify specified_etype_implements

[web/views] Fix `has_editable_relation` predicate wrt inlined relations Prevents the "modify" action from being shown when there is nothing to edit.

[web/views] avoid propagation of NoSelectableObject in some case of inlined relations / permissions When selecting an inlined creation form, we should catch the NoSelectable exception that will be raised if the user cannot add entities of the target type (this is not and cannot be verified earlier) or if some other custom selector prevents the form from being selected. Closes #6510921

[py3k] unicode → six.text_type

[devtools/testlib] Port CubicWebTC.view() to py3k testlib.TestCase.set_description's argument will eventually be printed out to sys.stdout/stderr. On python 2, this object takes bytes-like objects (eg, str) whereas python 3's takes unicode-like objects and handles the encoding on its own. Thus the 'str' type can used in both versions to eventually display the description on screen.

[hooks/syncschema] make sure CWUniqueTogetherConstraintDelOp happens before CWConstraintDelOp SQLServer refuses to index an unlimited text column, so we should drop unique_together constraints (which imply an index) before we drop size constraints. Closes #5560601.

[hooks/syncschema] only call "ALTER TABLE" once when changing a size constraint Until now we would: - remove the old size constraint from the in-memory schema - call update_rdef_column which removes the size restriction from the column's type - add the new constraint object - call update_rdef_column which adds the size restriction back This breaks on SQL Server when the column is involved in an index (e.g. as part of a multi-column unique constraint), because in the intermediate stage the column's type is "nvarchar(max)", which is not indexable. Of course we must still detect the case where a size constraint is really dropped and update the db schema accordingly. Closes #5557633.

[syncschema] only add to the `synchronized` set if all possible updates have been done Otherwise a simple sync_schema(syncprops=False) turns the subsequent sync_schema() calls into a no-op. Closes #6510918.

[qunit] remove unused 'data_files' parameter Its use was removed when we stoppped pointing firefox at file:// web/test/jstests/ajax_url2.html has never actually been used, it's only been ever mentioned in a QUnit comment.

[urlpublish] RESTPathEvaluator now use vid_from_rset This avoid cases where vid may be unexpectedly overwritten. For instance when you define a custom vid for a mime type in VID_BY_MIMETYPE, it will currently be overriden by the URL publisher when you access to /<etype> with the proper Accept header. To do so, a new 'check_table' argument is introduced, which may cause bw compatibility problems if the function has been monkey-patched. Also pep8 a bit the tests. Closes #5705835

[server] typo fix

[test] check that we reject an rqlexpression in computed relation perms

Fix (de)serialization of ComputedRelation read permissions For normal relation types, permissions don't need to be stored since they're just default values for the relation definitions. However, computed relations are serialized (as CWComputedRType), while their relation definitions are added at schema finalization time, and are only in memory. So add the 'read_permission' relation to CWComputedRType, and the appropriate hooks to save and restore those permissions. To avoid having to touch yams, we drop the 'add' and 'delete' permissions from the default computed relation permissions; this should probably be backported there. The actual permissions (set on the relation definitions) are hardcoded in finalize_computed_relations anyway. In deserialize_schema, the CWComputedRType handling needs to be delayed a little bit, until after we've called deserialize_ertype_permissions. The rql2sql test is adjusted because CWComputedRType has a 'name' attribute and the 'read_permission' relation, which generates ambiguity vs CWEType. We add an explicit CubicWebRelationSchema.check_permission_definitions, since we need to check both that computed and non-computed rtypes are defined properly. Based on report and initial patch from Christophe de Vienne (thanks!). Closes #5706307

Copy read permissions on ComputedRelation rdefs Closes #5694110

[datafeed] fix typo in DataFeedXMLParser.is_deleted (closes #5729755)

[server/sources] make sure entity._cw is a Connection before calling Storages The storage callbacks don't get an explicit Connection objects, so they go through entity._cw to access the repo and schedule operations. Since that entity object comes out of the entity cache, its _cw may be a web request instead of a Connection. So fix it up around the storage callbacks. Closes #5753543

[hooks] base64-encode extid before inserting it into moved_entities If we insert the wrong value we're never going to find these entities again... Closes #5741105.

[hook] remove assumption about entity cache vs cw_edited We were assuming that if an entity is in the connection's cache, it has a cw_edited attribute. This doesn't seem to always be the case. At least in cubicweb 3.21, merging the web and repo-side caches makes this more likely, but Denis says he's also seen this on 3.20.

[hook] don't open-code Connection.entity_cache

[tox] Add missing dependency on webtest for devtools tests

[tox] Remove set of PATH environment variable The : concatenation does not work actually so the resulting PATH was just wrong (it did not contain the previous PATH). Anyways, the PATH environment variable is passed by default by tox so it's probably better to let the caller set it (thus avoiding to hard-code the specific postgres version and path). http://tox.readthedocs.org/en/latest/example/basic.html#passing-down-environment-variables

Related to #5447161.

[schema] drop old backward compat code preventing yams to be itself fully cleaned

[datafeed] allow to use cwclientlib for datafeed's queries (closes #5456849) HTTP based URLs will be handled by a CWProxy if: - cwclientlib is available and - the URL matches a cwclientlibrc config entry Otherwise, fallback to previous implementation. See https://www.cubicweb.org/project/cwclientlib :Warning: This comes with an API modification of DataFeedParser.retrieve_url: it used to accept data and headers arguments to build GET or POST (if data was given) queries, but this was not used by any known code and imply more complicated code.

[cwxml parser] refactor url handling code to use urlparse and urlencode (related to #5456849)

[dataimport] dispatch and deprecate old code previously, the whole dataimport.py content has been copied in dataimport/__init__.py, then dataimport/importer.py API has been introduced. Following these changes, this cset: * dispatch __init__ code into sub-modules * dispatch unittest_dataimport accordingly * deprecates functions and classes that are deprecated by the new API Related to #5414753.

Add tox.ini file * Factor out `commands` for most environments using {envname} substitution to build pytest commande. * Positional arguments are passed on to `pytest` (others may also be passed after a `--`). * Set PATH env variable for tests requiring PostgreSQL. * Also added a `doc` target to build the book. Also update .hgignore exclude .tox directory (where virtualenvs will be created and cubicweb.egg-info created by sdist command). Closes #5447161.

Add requirements.txt files in test directories These files, located in each test directory (when needed), list test dependencies supplementary to install requirements. Some requirements.txt files include psycopg2 because it won't get installed by logilab-database apparently. Related to #5447161.

[statsd_logger] handle ipv6 addresses

implement a simple statsd logger (closes #5488711) and add a few timing probes on: - etwist.server.CubicWebRootResource.render_request() - server.querier.QuerierHelper.execute() - server.sources.native.NativeSQLSource: - sqlexec() - compile_rql() - authenticate() - doexec() - doexecmany() as well as a pair of counters on server.querier.QuerierHelper cache (hit/miss).

[predicates] ExpectedValuePredicate now accepts a dict parameter ``match_form_params`` and ``match_kwargs`` benefit from that. For instance, the following statements are valid:: __select__ = match_form_params('vid', 'subvid') __select__ = match_form_params(vid='list', subvid='incontext') __select__ = match_form_params(vid=('list', 'tsearch')) In the latter cases, not only the parameters (``vid``/``subvid``) must be in the request form but their corresponding value must also match the expected values (or one of possible choices if `values` is a sequence). closes #5484070

[rql2sql] Fix iter_exists_sols() excessive cleaning of _state.tables Closes #5503548

[test] Fix unittest_i18n to run properly with "pytest -t" (closes #5576169) When running "pytest -t", many tests modules will be imported and run within a single python process. unittest_i18n fails when run after tests such as unittest_webtest.py or unittest_httptest.py. The main reason is that unittest_i18n does various tricks to add a test cube to the search path, which badly fails when a previous test module has already loaded "stuff" (for lack of a better word). Instead, let's just call the 'i18ncube' command with subprocess. The change from logilab.common.testlib to unittest is not directly needed, but comes as a free cleanup with the above changes.

[server/test] fix random error in unittest_security When entering a new Connection, we cache the user and its 'login' attribute (with no permissions checking). This test makes 'CWUser.login' unreadable by guests, and then proceeds to make sure the 'anon' user can actually not read any 'login' attribute. However, due to the above cnx initialization, anon's login is actually cached, hence readable. This happens to make the test fail sometimes depending on the order in which CWUser entities are returned, because one of them has .complete() called, which as a side effect sets the attribute cache to None for unreadable attributes. Call .complete() on both entities to reset the login cache. While this is still highly debatable, at least it's consistent.

[entity] fix typo in comment

[doc] Add a tutorial and extend documentation for ExtEntityImporter Related to #5414753.

[dataimport] introduce the importer and extentity classes This introduces the ``ExtEntity`` class which is a transitional state between data at external source and the actual CubicWeb entities. ``ExtEntitiesImporter`` is then in charge to turn a bunch of ext entities into CW entities in repository, using a given store. This changeset also introduces ``SimpleImportLog`` and ``HTMLImportLog`` which implement the CW DataImportLog interface in order to show log messages in UI using simple text and HTML formats respectively, instead of storing these messages in database. Both have mostly been backported from cubes.skos.dataimport. Closes #5414753.

[test] Use store.prepare_insert_relation instead of deprecated relate method Follow-up for 1f5026e7d848. Related to #5040344.

[dataimport] since we have foreign key constraints in the database, 'entities' table should be updated first
