oops, missing return

we need extrapath when trying to import site_cubicweb files

move extra path computing as a configuration class property so we can reused it

first draft for a simple hooks based custom attribute storage, with a BytesFileSystemStorage POC implementation. Basically: * a dictionary contains maps from which attribute of which entity types are mapped to which custom storage * hooks check for one of these entity type being added/modified/deleted * read is based on the sql generator callback mecanism (used in vcsfile for instance) * all storages have the same basic interface (read, add, update, delete), and should be pluggable in a transparent way (except at migration time when one want to change from a storage to another) * the sample BytesFileSystemStorage: * may store Bytes attributes content of any entity type as file on the file system * is based on one FSPATH rql/sql function and another _fsopen only available in sql * has a dumb file name allocation algorithm

closes #345410: two_lines_rset, two_cols_rset, two_etypes_rset are badly named replaced by multi_lines_rset, multi_columns_rset, multi_etypes_rset, all taking optional 'nb' argument allowing to specify and exact count. Bw compat is kept, usage of deprecated function updated in cw itself. Also drop custom at_least_two_columns selector (in views.plots) since it was the same as multi_columns_rset. Hopefuly the renaming will help in avoid such pb... We should now decide if we want to deprecate one_* selector in favor of multi_*(nb=1). See note on this at then end of selectors.py

fix #636936: read_permission relation should not be mandatory

fix #615848: undefined 'new' variable was refering to the newly introduced subquery / remove_subquery doesn't take an undefine argument (probable copy/paste from the remove_node call)

some docstring

[doc] reformulate dependencies

[views] FinalView should display an empty string if value is None

merge

move base form renderer label handling into a function to reuse it in CompositeFormRenderer and avoid seeing a tuple in column headers...

minor schema deserialization optimizations

oopb, widget has been renamed

specify formvid=edition to get multiple edition working w/ 3.6

reminder

this clutter startup screen for little benefit, remove it

update copyright

move bookmark related uicfg stuff into bookmark specific module, use the EditableURLWidget widget for Bookmark.path

new field's responsibility POC: EditableURLWidget allow to edit Bookmark.path in two separated fields, displaying unquoted values which are requoted on form post processing

refactor field's value retreiving from the widget (eg 'display value' concept): * kill field's display_value method, since getting value specified in a previous post or in req.form should be the widget responsibility (the widget nows what inputs to display, not the field) * new typed_value / format_value on widgets, mainly to ease overriding

dom_id now accepts a suffix argument as input_name

cleaner input_name implementation
