[dbapi] fix connect backwards compat harder
Passing None as group and host should result in
"pyro:///cubicweb.appid", not "pyro://None/None.appid". Followup for
2091d275fe5c. Closes #2882666.
Whats new in CubicWeb 3.14==========================First notice CW 3.14 depends on yams 0.34 (which is incompatible with priorcubicweb releases regarding instance re-creation).API changes-----------*`Entity.fetch_rql``restriction` argument has been deprecated and should be replaced with a call to the new `Entity.fetch_rqlst` method, get the returned value (a rql `Select` node) and use the RQL syntax tree API to include the above-mentionned restrictions. Backward compat is kept with proper warning.*`Entity.fetch_order` and `Entity.fetch_unrelated_order` class methods have been replaced by `Entity.cw_fetch_order` and `Entity.cw_fetch_unrelated_order` with a different prototype:- instead of taking (attr, var) as two string argument, they now take (select, attr, var) where select is the rql syntax tree beinx constructed and var the variable *node*.- instead of returning some string to be inserted in the ORDERBY clause, it has to modify the syntax tree Backward compat is kept with proper warning, BESIDE cases below:- custom order method return **something else the a variable name with or without the sorting order** (e.g. cases where you sort on the value of a registered procedure as it was done in the tracker for instance). In such case, an error is logged telling that this sorting is ignored until API upgrade.- client code use direct access to one of those methods on an entity (no code known to do that).*`Entity._rest_attr_info` class method has been renamed to`Entity.cw_rest_attr_info` No backward compat yet since this is a protected method an no code is known to use it outside cubicweb itself.*`AnyEntity.linked_to` has been removed as part of a refactoring of this functionality (link a entity to another one at creation step). It was replaced by a `EntityFieldsForm.linked_to` property. In the same refactoring, `cubicweb.web.formfield.relvoc_linkedto`,`cubicweb.web.formfield.relvoc_init` and`cubicweb.web.formfield.relvoc_unrelated` were removed and replaced by RelationField methods with the same names, that take a form as a parameter.**No backward compatibility yet**. It's still time to cry for it. Cubes known to be affected: tracker, vcsfile, vcreview.*`CWPermission` entity type and its associated require_permission relation type (abstract) and require_group relation definitions have been moved to a new`localperms` cube. With this have gone some functions from the`cubicweb.schemas` package as well as some views. This makes cubicweb itself smaller while you get all the local permissions stuff into a single, documented, place. Backward compat is kept for existing instances, **though you should have installed the localperms cubes**. A proper error should be displayed when trying to migrate to 3.14 an instance the use `CWPermission` without the new cube installed. For new instances / test, you should add a dependancy on the new cube in cubes using this feature, along with a dependancy on cubicweb >= 3.14.* jQuery has been updated to 1.6.4 and jquery-tablesorter to 2.0.5. No backward compat issue known.* Table views refactoring : new `RsetTableView` and `EntityTableView`, as well as rewritten an enhanced version of `PyValTableView` on the same bases, with logic moved to some column renderers and a layout. Those should be well documented and deprecates former `TableView`, `EntityAttributesTableView` and `CellView`, which are however kept for backward compat, with some warnings that may not be very clear unfortunatly (you may see your own table view subclass name here, which doesn't make the problem that clear). Notice that `_cw.view('table', rset, *kwargs)` will be routed to the new `RsetTableView` or to the old`TableView` depending on given extra arguments. See #1986413.*`display_name` don't call .lower() anymore. This may leads to changes in your user interface. Different msgid for upper/lower cases version of entity type names, as this is the only proper way to handle this with some languages.*`IEditControlAdapter` has been deprecated in favor of `EditController` overloading, which was made easier by adding dedicated selectors called`match_edited_type` and `match_form_id`.* Pre 3.6 API backward compat has been dropped, though *data* migration compatibility has been kept. You may have to fix errors due to old API usage for your instance before to be able to run migration, but then you should be able to upgrade even a pre 3.6 database.* Deprecated `cubicweb.web.views.iprogress` in favor of new `iprogress` cube.* Deprecated `cubicweb.web.views.flot` in favor of new `jqplot` cube.Unintrusive API changes-----------------------* Refactored properties forms (eg user preferences and site wide properties) as well as pagination components to ease overridding.* New `cubicweb.web.uihelper` module with high-level helpers for uicfg.* New `anonymized_request` decorator to temporary run stuff as an anonymous user, whatever the currently logged in user.* New 'verbatimattr' attribute view.* New facet and form widget for Integer used to store binary mask.* New `js_href` function to generated proper javascript href.*`match_kwargs` and `match_form_params` selectors both accept a new`once_is_enough` argument.*`printable_value` is now a method of request, and may be given dict of formatters to use.*`[Rset]TableView` allows to set None in 'headers', meaning the label should be fetched from the result set as done by default.* Field vocabulary computation on entity creation now takes `__linkto` information into accounet.* Started a `cubicweb.pylintext` pylint plugin to help pylint analyzing cubes.RQL---* Support for HAVING in 'SET' and 'DELETE' queries.* new `AT_TZ` function to get back a timestamp at a given time-zone.* new `WEEKDAY` date extraction functionUser interface changes----------------------* Datafeed source now present an history of the latest import's log, including global status and debug/info/warning/error messages issued during imports. Import logs older than a configurable amount of time are automatically deleted.* Breadcrumbs component is properly kept when creating an entity with '__linkto'.* users and groups management now really lead to that (i.e. includes *groups* management).* New 'jsonp' controller with 'jsonexport' and 'ejsonexport' views.Configuration------------* Added option 'resources-concat' to make javascript/css files concatenation optional.
