4b5cea1ef8 [enhancement](fix)change ordinary type null value is \N,complex type null value is null (#24207) 2023-09-16 21:46:42 +08:00
268c867679 [Improve](serde)replace function_cast from_string to serde (#24087)
Now we can not support streamload with column which is map/array nested map/array
serde can do this now , so we can replace it
Notice. if item data in complex type data is empty we just return error, instead of makeup default value , because now we can not define right default for complex type

1d05feea1b [Feature](Nereids) add executable function to support fold constant for functions (#18209)
1. Add date-time functions for fold constant for Nereids.
This is the list of executable date-time function nereids supports up to now:
- now()
- now(int)
- current_timestamp()
- current_timestamp(int)
- localtime()
- localtimestamp()
- curdate()
- current_date()
- curtime()
- current_time()
- date_{add/sub}(),{years/months/days/hours/minutes/seconds}_{add/sub}()
- datediff()
- {date/datev2}()
- {year/quarter/month/day/hour/minute/second}()
- dayof{year/month/week}()
- date_format()
- date_trunc()
- from_days()
- last_day()
- to_monday()
- from_unixtime()
- unix_timestamp()
- utc_timestamp()
- to_date()
- to_days()
- str_to_date()
- makedate()

2. solved problem:
- enable datev2/datetimev2 default.
- refactor Nereids foldConstantOnFE and support fold nested expression.
- separate the executable into multi-files for easily-reading and adding new functions

961f5d1bb7 [feature](function)Add St_Angle/St_Azimuth function (#18293)
Add St_Angle/St_azimuth function:
St_Angle:
Enter three point, which represent two intersecting lines. Returns the angle between these lines. Point 2 and point 1 represent the first line and point 2 and point 3 represent the second line. The angle between these lines is in radians, in the range [0, 2pi). The angle is measured clockwise from the first line to the second line.

`

mysql> SELECT ST_Angle(ST_Point(1, 0),ST_Point(0, 0),ST_Point(0, 1));
+----------------------------------------------------------------------+
| st_angle(st_point(1.0, 0.0), st_point(0.0, 0.0), st_point(0.0, 1.0)) |
+----------------------------------------------------------------------+
| 4.71238898038469 |
+----------------------------------------------------------------------+
1 row in set (0.04 sec)
`

St_azimuth:
Enter two point, and returns the azimuth of the line segment formed by points 1 and 2. The azimuth is the angle in radians measured between the line from point 1 facing true North to the line segment from point 1 to point 2.
`

mysql> SELECT st_azimuth(ST_Point(0, 0),ST_Point(1, 0));
+----------------------------------------------------+
| st_azimuth(st_point(0.0, 0.0), st_point(1.0, 0.0)) |

6964d9f99c [fix](function) resubmit-fix AES/SM3/SM4 encrypt/ decrypt algorithm initialization vector bug (#17907)
* Revert "[fix](function) fix AES/SM3/SM4 encrypt/ decrypt algorithm initialization vector bug (#17420)"

This reverts commit 397cc011c4f1ba5a25c770258c13f1cd3f28b47d.

* [fix-resubmit](function) fix AES/SM3/SM4 encrypt/ decrypt algorithm initialization vector bug (#17420)

ECB algorithm, block_encryption_mode does not take effect, it only takes effect when init vector is provided.
Solved: 192/256 supports calculation without init vector

For other algorithms, an error should be reported when there is no init vector

Initialization Vector. The default value for the block_encryption_mode system variable is aes-128-ecb, or ECB mode, which does not require an initialization vector. The alternative permitted block encryption modes CBC, CFB1, CFB8, CFB128, and OFB all require an initialization vector.

Reference: https://dev.mysql.com/doc/refman/8.0/en/encryption-functions.html#function_aes-decrypt

Note: This fix does not support smooth upgrades. during upgrade process, query may report error: funciton not found
