Release notes - NHibernate - Version 5.2.0

6
+ 132 issues were resolved in this release.

+
8
+ ##### Possible Breaking Changes #####
9
+ * With PostgreSQL, an HQL query using the bitwise xor operator "^" or "bxor"
10
+ was exponentiating the arguments instead. It will now correctly apply the xor
11
+ operator. (# operator in PostgreSQL SQL.)
12
+ * Auto-generated constraint names will not be the same than the ones generated
13
+ with previous NHibernate versions under .Net Framework. (Under .Net Core those
14
+ names were anyway changing at each run.) The new ones will be the same
15
+ whatever the runtime used for generating them.
16
+ * Some generated PK names may change, if a table name has a quoting symbol at
17
+ precise 13th character.
18
+ * The WcfOperationSessionContext has been removed from .Net Core and .Net
19
+ Standard builds. See #1842.
20
+ * Some types cache representations have changed. Out-of-process second level
21
+ caches should be cleared after upgrading NHibernate, if some of those types
22
+ were cached. The concerned types are: CultureInfoType, TypeType, UriType,
23
+ XDocType, XmlDocType.
24
+ * NHibernate StringType has gained case-sensitivity and culture parameters.
25
+ Previously it was ignoring parameters. This type may change its behavior
26
+ for any mapping having defined parameters for this type. See #1833.
27
+ * Querying a dynamic entity as a Hashtable instead of an IDictionary is no more
28
+ supported.
29
+ * Mapping a dynamic component with a Hashtable property instead of an
30
+ IDictionary is no more supported.
31
+ * Dialect.GetIdentitySelectString was called by the entity persisters with
32
+ inverted parameter values: the table name in the column parameter, and the
33
+ column name in the table parameter. No built-in dialects were using the
34
+ parameter values. External dialects which were using it inverted (causing issues
35
+ to collection persisters, which have always supplied them correctly) needs
36
+ to be accordingly adjusted.
37
+ * Users providing through an IObjectFactory some custom logic for instantiating
38
+ value types will now need to supply their own result transformer if they were
39
+ using AliasToBeanResultTransformer with value types, or their own entity
40
+ tuplizer if they were using value types as entities.
41
+ * Users providing through an IObjectFactory some custom logic for instantiating
42
+ their custom session contexts will have to implement
43
+ ICurrentSessionContextWithFactory and add a parameterless public constructor
44
+ to their custom context, and move their custom instantiation logic from
45
+ IObjectsFactory.CreateInstance(Type, object[]) to
46
+ IObjectsFactory.CreateInstance(Type).
47
+ * Various *Binding classes of NHibernate will now always have their protected
48
+ dialect field null. (These classes are not expected to be derived by users,
49
+ as there is no way to use custom descendants with NHibernate.)
50
+ * AbstractPersistentCollection.AfterInitialize does no more perform queued
51
+ operations. Queued operations are now run by a later call to a new method,
52
+ ApplyPendingOperations. Concrete custom implementations relying on the queued
53
+ operations to be done by their base AfterInitialize will need to be changed
54
+ accordingly.
55
+
56
+ Not yet merged possible breaking changes:
57
+ * ISession.Persist will no more always trigger immediate insertion of entities
58
+ having an identity-like id generator. See #1754.
59
+ * Mappings mixing column elements and formula elements were taking into account
60
+ only the formula elements, excepted for many-to-one which which taking into
61
+ account both element types. They will now all take into account all elements.
