[storage] relies on event=='deleted' to detect "delete" event (closes #2450680) When we delete a previously edited entity, it *will* have a cw_edited attribute even if the goal is to delete it. The function get an argument that explicitly contains the "delete" event. The code now uses that instead.

[composite] apply composite on new enty too Before this changesets, automatic deletion did not applied to entity created in the same transaction. This patch remove this filtering in the dedicated operation. The original filtering where introduced by 5d889b4928bb but no rational where found for this changes. The former behavior is seen as inconsistent and creates bug in some cubes.

[web navigation] previous / next icons are missing mandatory alt attribute

[testlib] consider rset for template / view selection (closes #2447183) The original code did something like: kwargs['rset'] = rset viewfunc = lambda **k: viewsreg.main_template(req, template, **kwargs) kwargs.pop('rset') return self._test_view(viewfunc, view, template, kwargs) meaning that by the time ``viewfunc`` (i.e. the lambda function) is called, ``rset`` was popped from ``kwargs`` and had no chance to be passed to ``main_template``.

[documentation] fix some ReST compilation problems

[test] remove no more necessary attribute cache manipulation to repair test

[entity] more tweaks for entity attribute cache handling on cw_set/cw_create to fix test regression * when an attribute is listed in dont-cache-attrs, purge any previous value * test value is actually modified in EditedEntity.__setitem__ before adding attribute to dont-cache-attrs

[entity/hooks] fix regression introduced by 4ba11607d84a on create_entity, attributes weren't cached, but they are since 4ba11607d84a and this triggered a bug: used values may be transformed by hooks (e.g. TidyHtmlFields), ending in invalid value in the cache. This is the regression. Now, set_attributes used to update the attributes cache while suffering from the very same pb. This is the now fixed old bug. Transformed attributes are now recorded in a transaction shared variable, and those are omitted from the client cache.

[login] redirect to real instance root if no postlogin_path is provided When not postlogin_path is provided, the login form issue a redirect to "/". The instance root may not be at "/" on the server. Then issuing a redirect to "/" send the user to the wrong location. We now redirect to "." which works fine because the "login" controller a direct children of instance root (http://babar.com/instance/login). All other redirection of the login controller use relative path too and then rely on this relative path from the login controleur to the instance root. This mechanism may be considered fragile and may deserve a proper fix. but this is to be discussed and implemented in another changeset.

[web/application] declare default 'content' value sooner (closes #2406560) It may be used while processing AuthenticationError. Such error may be raised before the former declaration.

[static-file] return Unauthorized on blocked directory listing This is more appropriate than 404 NOT FOUND

[login redirect] only add postlogin_path argument when meaningful

static-file: properly set/use cache header for static file (closes #2255013) This changesets enables the standard http cache mechanism where the static controller may reply "304 Not modified" based on `last-modified` in HTTP response and `if-modified-since` in HTTP query. The last modified time is computed using the file-system information. The pre-existing logic using an `Expires` header to prevent client from sending request stay in place. The new logic just prevents sending the file again if not necessary.

[repository] move task manager instantiation outside repository. Repository callers are in charge of providing a task manager. The task manager is optional when the repository is not a server. This part is not really expected to work well yet. But we aim to remove all task management responsibilities from the Repository object.

[repository] split repo initialization from starting looping task (closes #2204047) This separation highlights that two distinct operations are done. This is a step towards a full distinction between repo, server and looping tasks

[repo looping task] move looping task logic in a dedicated object (progress #2204047)

[security] use a stronger encryption algorythm for password, keeping bw compat Administrator should ask their users to reenter new password so they benefit from the new encryption. Also, new encryption is cross-platform compatible, eg you may now move an instance from windows to linux painlessly

[cache] factorize _validate_cache() logic implemented in wsgi and twisted handlers

[fake-request] support `http_method()`

[Web-Request] Use rich header (closes #2204164) Unify header management. All web request use the Headers class now (imported from twisted). Code dedicated to header management have been merged into the base WebRequest class.

http-header: support __contains__ in Headers You can now use:: >>> 'expires" in headers True

[web] Move request handling logic into cubicweb application. (closes #2200684) We improve http status handling in the process: ``application.publish`` have been renamed to ``application.handle`` to better reflect it's roles. The request object gain a status_out attribute to convey the HTTP status of the response. WSGI and etwist code have been updated. Exception gain status attribute

[login] split authentication logic from post authentication logic (closes #2200755) * The Session manager is now only in charge of providing a valid session. * LoginControllers are now used in all case but wrong credential. * The LoginControllers are in charge of redirecting the user to the page wanted to see in the first place, expected to see. * The login form is now always submitted to the login controller with an extra argument pointing to the url we should redirect too after successful authentication. The ``"log out first logic"`` logic on login controller is removed because: 1. Other web actor do not do that. 2. Removed code do not need to be reimplemented. 3. We can only get it to work again in a single case: use do a GET request on http://www.my-cw-stuff.io/login 4. I do not see it's purpose.

[LoginForm] refactor to ease other implementation An Abstract BaseLoginForm is created. It is intended to be used by cubes who want to implement new login form. It gather common login form elements in particular the form action. This will ease redefinition of this form action in later commit.

[request] gather all base_url logic in a single place (closes #2200756) * Handle ``https base-url`` in the core code: ``./req.py`` and ``web/request.py`` * Remove custom ``base_url`` handling if web request

[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).

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.

We change this for it to raise an UndoException with the list of errors as an attribute. 2) The server-side support for undoing update actions is finished 3) The configuration for `undo-support` is now a simple boolean Beware of the costs, both in DB space and in number of requests on the RDBMS backend, once this feture is activated. 4) Adds a txuuid param/attribute to the existing NoSuchTransaction exception.

So make a local copy of xvfb-run, and make it kill Xvfb when it goes down, not just when its client exits.
