new 141bcd6e8 [OPENJPA-2933] Implements new date JPA 3.1 JPQL functions
and equivalent Criteria API (#123)
141bcd6e8 is described below
commit 141bcd6e8e61486a4f1d653ec040c6bdc7976745
Author: Paulo Cristovão de Araújo Silva Filho <pcris...@gmail.com>
AuthorDate: Sat Feb 8 10:49:14 2025 -0300
[OPENJPA-2933] Implements new date JPA 3.1 JPQL functions and equivalent
Criteria API (#123)
* OPENJPA-2908
* Bumped jakarta persistence API to 3.1.0
* Added necessary stub impl of methods (throws
UnsupportedOperationException)
* Tests passes, but actual impls must be made in probably different issues,
one for each new features
(https://jakarta.ee/specifications/persistence/3.1/jakarta-persistence-spec-3.1#jakarta-persistence-3-1)
* [OPENJPA-2933] Implements LOCAL DATE, LOCAL TIME, LOCAL DATETIME and
EXTRACT functions
* Added JPA 3.1 date/time JPQL new functions LOCAL DATE, LOCAL TIME and
LOCAL DATETIME and Criteria equivalents
* Added JPQL EXTRACT date/time field and EXTRACT date/time (as a CAST) JPQL
functions
* Added tests to verify validity of BNF changes in JPQL.jjt and each new
function
* [OPENJPA-2933] Fixing typo and postgresql extract function
* [OPENJPA-2933] Decreasing lookahead instruction of extract for better
performance
* [OPENJPA-2933] Finishing implementation
* Updated round function usage and test due a corner case on postgresql
tests
* Made EXTRACT function test be resistent to date/time divergence between
db and test environments
* Updated manual BNF and Date Time functions chapters
