1 What's new in CubicWeb 3.18? |
|
2 ============================ |
|
3 |
|
4 The migration script does not handle sqlite nor mysql instances. |
|
5 |
|
6 |
|
7 New functionalities |
|
8 -------------------- |
|
9 |
|
10 * add a security debugging tool |
|
11 (see `#2920304 <http://www.cubicweb.org/2920304>`_) |
|
12 |
|
13 * introduce an `add` permission on attributes, to be interpreted at |
|
14 entity creation time only and allow the implementation of complex |
|
15 `update` rules that don't block entity creation (before that the |
|
16 `update` attribute permission was interpreted at entity creation and |
|
17 update time) |
|
18 |
|
19 * the primary view display controller (uicfg) now has a |
|
20 `set_fields_order` method similar to the one available for forms |
|
21 |
|
22 * new method `ResultSet.one(col=0)` to retrive a single entity and enforce the |
|
23 result has only one row (see `#3352314 https://www.cubicweb.org/ticket/3352314`_) |
|
24 |
|
25 * new method `RequestSessionBase.find` to look for entities |
|
26 (see `#3361290 https://www.cubicweb.org/ticket/3361290`_) |
|
27 |
|
28 * the embedded jQuery copy has been updated to version 1.10.2, and jQuery UI to |
|
29 version 1.10.3. |
|
30 |
|
31 * initial support for wsgi for the debug mode, available through the new |
|
32 ``wsgi`` cubicweb-ctl command, which can use either python's builtin |
|
33 wsgi server or the werkzeug module if present. |
|
34 |
|
35 * a ``rql-table`` directive is now available in ReST fields |
|
36 |
|
37 * cubicweb-ctl upgrade can now generate the static data resource directory |
|
38 directly, without a manual call to gen-static-datadir. |
|
39 |
|
40 API changes |
|
41 ----------- |
|
42 |
|
43 * not really an API change, but the entity permission checks are now |
|
44 systematically deferred to an operation, instead of a) trying in a |
|
45 hook and b) if it failed, retrying later in an operation |
|
46 |
|
47 * The default value storage for attributes is no longer String, but |
|
48 Bytes. This opens the road to storing arbitrary python objects, e.g. |
|
49 numpy arrays, and fixes a bug where default values whose truth value |
|
50 was False were not properly migrated. |
|
51 |
|
52 * `symmetric` relations are no more handled by an rql rewrite but are |
|
53 now handled with hooks (from the `activeintegrity` category); this |
|
54 may have some consequences for applications that do low-level database |
|
55 manipulations or at times disable (some) hooks. |
|
56 |
|
57 * `unique together` constraints (multi-columns unicity constraints) |
|
58 get a `name` attribute that maps the CubicWeb contraint entities to |
|
59 corresponding backend index. |
|
60 |
|
61 * BreadCrumbEntityVComponent's open_breadcrumbs method now includes |
|
62 the first breadcrumbs separator |
|
63 |
|
64 * entities can be compared for equality and hashed |
|
65 |
|
66 * the ``on_fire_transition`` predicate accepts a sequence of possible |
|
67 transition names |
|
68 |
|
69 * the GROUP_CONCAT rql aggregate function no longer repeats duplicate |
|
70 values, on the sqlite and postgresql backends |
|
71 |
|
72 Deprecation |
|
73 --------------------- |
|
74 |
|
75 * ``pyrorql`` sources have been deprecated. Multisource will be fully dropped |
|
76 in the next version. If you are still using pyrorql, switch to ``datafeed`` |
|
77 **NOW**! |
|
78 |
|
79 * the old multi-source system |
|
80 |
|
81 * `find_one_entity` and `find_entities` in favor of `find` |
|
82 (see `#3361290 https://www.cubicweb.org/ticket/3361290`_) |
|
83 |
|
84 * the `TmpFileViewMixin` and `TmpPngView` classes (see `#3400448 |
|
85 https://www.cubicweb.org/ticket/3400448`_) |
|
86 |
|
87 Deprecated Code Drops |
|
88 ---------------------- |
|
89 |
|
90 * ``ldapuser`` have been dropped; use ``ldapfeed`` now |
|
91 (see `#2936496 <http://www.cubicweb.org/2936496>`_) |
|
92 |
|
93 * action ``GotRhythm`` was removed, make sure you do not |
|
94 import it in your cubes (even to unregister it) |
|
95 (see `#3093362 <http://www.cubicweb.org/3093362>`_) |
|
96 |
|
97 * all 3.8 backward compat is gone |
|
98 |
|
99 * all 3.9 backward compat (including the javascript side) is gone |
|
100 |

|
