cubicweb: Changelog

[datafeed xml parser] fix typo

[twisted] move out url logic from twisted (closes #2200593) Data, fck and static file are now served by cubicweb controller by default. Some hackish url rewriting is necessary to have them selected. This is necessary because cubicweb does not selection controller on multi level path. - 'Expires' header seems to conflict with Cache-Control set by HTTPCacheManger (don't know yet why HTTPCacheManager is involved here) mod_wsgi is now usable in simple cases (e.g. still requires persisten sessions).

[cwconfig] improve assert error message. Single tuple element are processed in a non trivial way.

rqlrewrite: remove element in rewritten when we remove them from the select (closes #2236985) update _cleanup_inserted to avoid leaving rewritten variable behind when removing a snipset. insert_varmap_snippets was impacted too for unclear reason --- Before A KeyError was raised when: * multiple snipset is to be inserted on a statement * some *supported* snipset adds ambiguity (increase the number of solution) * some *unsupported* snipset adds new variable * The new variable require rewritting :: File "/home/pyves/src/fcw/cubicweb/rqlrewrite.py", line 185, in rewrite newsolutions = self.remove_ambiguities(snippets, newsolutions) File "/home/pyves/src/fcw/cubicweb/rqlrewrite.py", line 436, in remove_ambiguities variantes = self.build_variantes(newsolutions) File "/home/pyves/src/fcw/cubicweb/devtools/repotest.py", line 340, in _build_variantes variantes = _orig_build_variantes(self, newsolutions) File "/home/pyves/src/fcw/cubicweb/rqlrewrite.py", line 470, in build_variantes variante.append( (key, sol[newvar]) ) KeyError: u'D' This happen because the mechanism removing unsupported snipset does not remove entry in ``self.rewritten`` when it removes entry from ``self.select.defined_vars``. Iteration on ``self.rewritten`` then crash because values of ``rewritten`` are expected to be found in solution.
