i18n update 4 strings have disappeared.

[pkg] 3.19.5

[server] hold connection to the db in tx_actions We can be called without a cnxset (e.g. from repoapi).

[wsgi] If multipart cannot parse the POST content, let it pass. multipart can only parse html form data. It the content_type is, for example, "application/json", get_posted_data should not fail but just stop trying to read the content. Closes #4421845

[devtools] Fix JS tests' HTML code

[devtools] "Keep" some temporary files/dirs around to help with debugging The whole QUnitTestCase runs with an @with_tempdir so it's redundant anyway.

[devtools] Fix Firefox launcher in QUnitTestCase (closes #4294727) The main changes are: - stop creating the profile, firefox will create it - point firefox to a profile directory instead of giving it a profile name (this has the added bonus of not polluting the user's profile list) - start firefox once and kill it 5 seconds later to let it finish its profile creation (along with system-wide extensions setup)

[devtools] allow cross-origin requests for qunit We have a mix of file:// html and http:// ajax calls. Which we should at some point fix to all be http, but. Related to #4294727.

merge 3.19.4 in 3.20 branch

[cors] Fix CORS headers generators The Access-Control-Allow-* and Access-Control-Expose-Headers are response headers, not request headers. Hence, we need generators for them. Closes #4412575.

[wsgi] Fix posted files filename reading The filenames are parsed by multipart.parse_form_data, which does the unicode decoding. Trying to re-decode the filename was leading to an error.

[pkg] Depend on Pillow instead of PIL The Pillow library is becoming the de-facto replacement for PIL. It also is way simpler to install with pip than PIL. Closes #4411354.

Added tag cubicweb-version-3.19.4, cubicweb-debian-version-3.19.4-1, cubicweb-centos-version-3.19.4-1 for changeset c4e740e50fc7

[pkg] 3.19.4

merge 3.18.6 into 3.19

Added tag cubicweb-version-3.18.6, cubicweb-debian-version-3.18.6-1, cubicweb-centos-version-3.18.6-1 for changeset d91501356742

[pkg] 3.18.6

[hooks/security] allow edition of attributes with permissive permissions If an attribute has more permissive security rules than the entity type itself, we should be green and not deny action because of an early global entity permission check (with the more restrictive rules). Only if one attribute with the entity-level permission rules is edited will the global check be performed. Note: * the "if action == 'delete'" check at the entry of check_entity_attributes is a guard for a condition currently not happening in cubicweb itself (but application hooks could conceivably call this function with a 'delete' action) Closes #3489895.

Almost backout afcd46716d6a which breaks _select_best raising an ambiguity exception in debug mode. The problem is, before afcd4, *tests* ran in debug mode and we want this (e.g. we want to show, rather than swallow, select ambigüities). We juste replace the bogus __init__(vreg.config) by __init__(True), which is practically equivalent and also much more clear.

[server] fix anonymous_user predicate in tests devtools' TestServerConfiguration overrides the anonymous_user method, but not the anonymous-user config option, so testing for the latter would give the wrong result. Closes #3996664.

[entities] cw_rest_attr_info() should only consider required attributes (closes #3766717) This prevents CW from choosing unique but non-required attributes. None/NULL is a poor choice for RESTful URIs.

[views] csvexport accept an empty rset (closes #4236928) When you tried to apply the 'csvexport' view on an empty rset, the view couldn't be selected and you got a HTTP 500 error. Also add two new test cases.

[views] Display attributes in entity creation form based on "add" permission Previously, the "update" permission was used. Hence in case the latter is more restrictive that the "add" permission, an user may not be able to set such an attribute, despite she may have "add" permission on it. As a result of the change of permissions action in `editable_attributes` method (add/update depending on whether the entity is being created or modified), the "eid" attribute would have shown up in the edition form. To avoid this, it is moved in the "hidden" section (where it should arguably belong anyways). Closes #4342844.

[datafeed] Commit after all deletions in datafeed parser This avoids misleading validation error because schema constraints could be temporarily broken depending on the deletion order. Closes #4372127.

[schema] CWComputedRType is a schema type Hide it from the default views.

[doc] proofreading CWEP002 section

[CWEP002] document computed relations and attributes Related to #3546717.

[CWEP002 migration] support sync_schema_props_perms for computed attribute

[CWEP002 migration] support drop_relation_type/drop_relation_definition/drop_attribute for computed attributes

[CWEP002 migration] support add_relation_type/add_attribute for computed attributes Related to #3546717.

[CWEP002] properly handle serialization of computed attributes Until this cset, only serialization of computed attribute's formula was handled (thanks to the relation definition's properties dict). We now: * properly serialize/deserialize attribute's formula * test first if the database has been migrated and contains related column or not Related to #3546717

[CWEP002] Add support for computed attribute synchronization Related to #3546717. Test and handle the behaviour with several formulas and identified use cases. To do so add a birth year and a computed attribute age to Person in the test schema.

[CWEP002] Add schema finalization checks for computed attributes ``finalize_computed_attributes`` essentially checks that computed attributes types match with the type declaration of the attribute. Related to #3546717.

[CWEP002] Account for attribute formula in schema bootstrap This isn't enough to have computed attribute support, it is only in order not to crash when yams 0.40 is used. Related to #3546717.

[CWEP002 migration] support sync_schema_props_perms for computed relations

[CWEP002 migration] support add_relation_type for computed relations Related to #3546717.

[CWEP002 migration] support drop_relation_type for computed relations Related to #3546717.

[CWEP002 migration] properly raise exception on (add|drop)_relation_definition for computed relation Related to #3546717

[hooks] do not abuse of inheritance for CWRType hooks Just copy the selector to ease readability.

[schema serial] add some comments

[schema] define full_rql on RQLExpression class without it, we may have an error while displaying error which occured during some expression initialization because this attribute is not yet defined while used in the __str__ method.

[schema] properly raise BadSchemaDefinition when some expression mains variables may not be guessed

[CWEP002] properly handle serialization of computed relations We now: * have CWComputedRelation in the bootstrap schema to store computed relations * properly serialize/deserialize it * test first if the database has been migrated and contains the related table Related to #3546717 [jcr: adjust unittest_querier to pass with the added entity type]

[CWEP002] Plug the computed relation rewriter in the querier Related to #3546717.

[CWEP002] refactor rql read security checking Split 'check_read_perms' into 'check_relations_perms' which checks relations 'read' permissions and 'get_local_checks' which build dictionary of local security checks (rql expression) for variables. This allows to check relations 'read' permissions earlier in the process and so to prepare insertion of the rql rewriter: we want to check permissions of the computed relation, not permissions of relations introduced by the associated rule, to conform to the CWEP. Related to #3546717

[CWEP002] introduce RQLRelationRewriter Refactor existing RQLRewriter for later reuse of rewriting relation as specified by CWEP002. Work is different because we simply want to replace a relation by another rql snippet and we don't have to bother with EXISTS, subqueries and all. This rewriter is not yet plugged into the querier. Depends on yams 0.40 API. Related to #3546717

[CWEP002] Add schema finalization checks for computed relations (rules) Related to #3546717

[schema] add utility function to build a CubicWebSchema from a namespace Will be useful for testing computed attributes and relations.

Fix test migration crash waiting to happen due to inferred relations Avoid crashing when a relation definition which is already known (due to being inferred) gets explicitly added. As explained in a comment, this would deserve more thinking, but at least this fixes a test failure with computed relations.

fix typo in syncschema hooks

[test] Make test_undo_api less random The order in which hooks are run is not predictable if they have the same 'order' attribute, which is the case for SetOwnershipHook and SetInitialStateHook. So don't assume in_state will be set before created_by.

merge 3.17.17 into 3.18 branch

[wsgi] Fix unicode decoding in POST The application/x-www-form-urlencoded sent by firefox or chrome is utf-8 encoded BEFORE being urlencoded. Hence, decoding must urldecode THEN decode the utf-8 string, and not the other way around.

[wsgi] add the --debug / -D option to the wsgi command

[wsgi] Fix multiple variables reading in params Closes #4306081

[wsgi] Set self.vreg Closes #4306049

[wsgi] Add missing import Closes #4305988

[wsgi] Fix https detection - 'HTTPS' is not part of wsgi, it is a CGI variable. The right wsgi variable is 'wsgi.url_scheme' - Force https if url starts with '/https/' (and remove the prefix from the path. Closes #4305985

[wsgi] Re-set the request content after calling the inherited constructor. Closes #4191813

[wsgi] Honor the 'CONTENT_TYPE' wsgi variable See http://legacy.python.org/dev/peps/pep-0333/#environ-variables Closes #4191812

Added tag cubicweb-version-3.17.17, cubicweb-debian-version-3.17.17-1, cubicweb-centos-version-3.17.17-1 for changeset 57e9d1c70512

[pkg] prepare 3.17.17

[web/headers] don't list a request header twice in "Vary"

[test] silence a few more deprecation warnings in unittest_hooks self.session → cnx.

[session] call rollback in Connection.__exit__ If we just free the cnxset and clear the Connection, we're missing the pending operation's rollback_event callbacks, which may be needed for cleanup.

[devtools] pre_setup_database takes a Connection, not a Session

[source/native] cPickle is available in all supported pythons

devtools: deprecate .req_from_url Which uses .request() And instead provide .admin_request_from_url, which is a context manager yielding the request.

[tests] Add a webtest based TestCase class Closes #4002134

[tests] Move 'anonymous_allowed' property from CubicWebServerTC to CubicWebTC The effective set of the property on the config is now done later that before, ie at the end of CubicWebTC.init_config instead of before. It is believed not to have an impact on the test suites that uses `anonymous_allowed`. Related to #4002134

[compat] Remove imports of "any" and "all" from lgc (closes #4306044) They're builtin since python 2.5.

[css] Remove the `div` tag specification of the pendingDelete css rule The HTML tag was changed by e2f96b16c3bd from a div to a span without changing the css rule accordingly. Closes #4285248.

[cwvreg] cleanup the event manager when reloading modules Closes #3848995 The event manager callbacks are not cleaned during reloading. So the callback defined in the reloaded module appears twice (old and new version). This may cause problem when the old version is called.

[test] Add missing attribute 'add' permission in test schema Silences yams warning.

[facet html] Add surrounding div with "facetBody" class to "has_text" facet. This makes its html structure consistent with the other facets and fixes both css and a javascript behaviour (hide the facet body when clicking on its title). Closes #3797501.

[cwctl] don't prompt for cube options in automatic mode Closes #3984223

[serverctl] fix default value for db-init config-level Otherwise cubicweb-ctl db-init --automatic complains that "--automatic and --config-level should not be used together" when they weren't. Closes #3984336

[web] Return useful error messages when exceptions arise in ajax controllers (closes #3932503) The call to super() in RemoteCallException passes 'reason' all the way to python's Exception.__init__() which is then stored in Exception.args. This way, CubicWebPublisher.ajax_error_handler() gets a useful error message when calling unicode(exc). The change to uilib is just to prepend the exception type name. Just a small improvement.

[test] Fix test breakage uncovered by previous changeset Now that Binary.__eq__ doesn't always return true, this test started failing. CWAttribute.defaultval is zpickled, and the description_format attribute is a String, meaning unicode, so adjust the expected test result.

[etwist] use more specific REQUEST_ENTITY_TOO_LARGE instead of BAD_REQUEST When a request body exceeds the configured limit, return 413 to the client instead of a generic 400.

[entities, view] delete dead code The auto_unwrap_bw_compat metaclass calls unwrap_adapter_compat, which was removed in changeset 697a8181ba30 "remove 3.9 bw compat". So this can't possibly work anymore, meaning we can get rid of it.

[book] stop talking about the hg `forest` extension

[book] update sections about dependencies This is probably incomplete, but it's a start.

[web/component] move unicode() call around Makes Aurélien happier.

[web/js] replace callAddOrDeleteThenReload with more generic callAjaxFuncThenReload That's going to be a more useful replacement for callUserCallbackThenReload. Closes #4178566.

[hooks/syncsession] try to remove cnx vs session confusion

Fix Binary.__eq__ (closes #4172701) Due to a typo we always returned true, which was unhelpful.

[dataimport] stop ignoring errors on flush That can only result in database corruption.

[dataimport] don't commit on flush Changeset 26cdfc6dd6f8 introduced this confusion for no apparent reason, and it doesn't make much sense.

[test] Add test for dataimport's RQLObjectStore

[dataimport] Stop swallowing errors from commit/flush Silent DB corruption is not OK. Also drop comment from ObjectStore.commit that I don't understand.

[dataimport] Update RQLObjectStore to Connection API Take a connection instead of a session. Don't play games with set_cnxset.

[dataimport] remove _rql heresy 1) ObjectStore knows nothing about rql, it just drops it on the floor 2) RQLObjectStore has a session, it can run rql that way 3) setting an object's "_rql" attribute is not a reasonable user-facing interface Also drop _commit attribute from base ObjectStore, it doesn't use it.

[dataimport] remove dead code The only caller of ObjectStore._put is ObjectStore.create_entity, which RQLObjectStore overrides (and doesn't call up).

[dataimport] do not use sys.exit() to raise missing argument error Related to #3845572

[dataimport] _create_copyfrom_buffer: add the tests Related to #3845572

[dataimport] _create_copyfrom_buffer: do not ignore columns if data is a list Related to #3845572

[dataimport] _create_copyfrom_buffer: fix datetime converter + add time converter Include second and microsecond in the output instead of dropping them on the floor. The time zone is not supported for now, though. Related to #3845572

[dataimport] _create_copyfrom_buffer: raise ValueError if conversion cannot be performed If the conversion fails, there is no reason to continue execution. One should notify the error. Continuing after a misconverted data could corrupt the database. Related to #3845572

[dataimport] _create_copyfrom_buffer: fix separator check in string converter The empty string is a valid replace_sep. Related to #3845572

[dataimport] _create_copyfrom_buffer: put converters into a list Cleans up the code to avoid a succession of ifs. Related to #3845572

merge 3.19.3 into 3.20 branch

Added tag cubicweb-version-3.19.3, cubicweb-debian-version-3.19.3-1, cubicweb-centos-version-3.19.3-1 for changeset 37f7c60f89f1

[pkg] prepare 3.19.3

merge from 3.18 branch

merge 3.17.16 into 3.18 branch

Remove uses of logilab.common.compat.{all,any} They're just aliases to the builtin ones on python 2.5+. If anyone needs convincing: >>> from logilab.common import compat >>> compat.any <built-in function any> >>> compat.all <built-in function all>

remove references to global environment variable APYCOT_ROOT

Add warning messages when enabling remote pickle-based repository access Warn when starting a pyro or zmq-only repo, or when one of these access methods is enabled. Closes #2919295

[web] Fix expiry of anonymous sessions (closes #4154479) Things like: try: foo except: bar else: baz doesn't work very well if you expect baz to run even in the exception case. Plus, session.cnx.check() is a dbapi remnant, so drop it and just look at session.mtime.

[hooks/syncschema] avoid altering a dropped table If the constraint's rdef is being removed, CWConstraintDelOp doesn't need to do anything. Otherwise it may try to alter a removed table/column. Closes #4154549

[js] fix name error

[devtools] improve error message when postgresql tools are missing By default in at least Debian, some pg tools are not present in the PATH. Or they may not be installed. But the tests tools expects them to be in the PATH, and give an unhelpful 'No such file or directory' backtrace if they're not found. To help devs using the pg tests we improve the error message.

[server] Replace non portable strftime formatter (closes #4132161)

[web/request] use a picklable Counter object for tab index counters Related to #1381328.

[web/auth] The auth retriever's authenticated() callback takes a session, not a cnx We don't have a cnx at that point.

[test] Fix the query-log-file test Testing this functionality in a CubicWebTC is awkward because the wrapping happens in handle_request, which tests basically bypass (they call core_handle directly, and do their own magic for linking the request with a cnx). The test method worked when ran on its own, but not together with the rest of the test class. So use a CubicWebServerTC instead, which goes through the whole stack.

[doc/book] spelling fixes in security tutorial
