ISSUE: 6013
|
||
TITLE: Date-time parsing is very weak
|
||
DESCRIPTION:
|
||
Parser changed in:
|
||
https://github.com/FirebirdSQL/firebird/commit/ff37d445ce844f991242b1e2c1f96b80a5d1636d
|
||
See also:
|
||
- CORE-6427 - Whitespace as date separator causes conversion error.
|
||
- CORE-6429 - Timezone offset in timestamp/time literal and CAST should follow SQL standard syntax only.
|
||
JIRA: CORE-5750
|
||
FBTEST: bugs.core_5750
|
||
NOTES:
|
||
[03.06.2023] pzotov
|
||
If source string contains binary characters (e.g. '2001') then it will not be converted to date,
|
||
but content of error message depends on FB version:
|
||
* on FB 4.x and FB 5.x prior 5.0.0.1058 it will look without changes, i.e. "2001";
|
||
* on 5.0.0.1058 it will look like this: conversion error from string "2029\x01\x19";
|
||
* on 5.0.0.1066 it will look like this: conversion error from string "2029#x01#x19";
|
||
Error text became differ after 30-may-2023:
|
||
https://github.com/FirebirdSQL/firebird/commit/fa6f9196f9015d0cf8c1cb84ff6312934855e9e9
|
||
("Fixed #7599: Conversion of text with '\0' to DECFLOAT without errors")
|
||
Expected STDERR was adjusted to current output after discuss with Alex.
|
||
|
||
[17.06.2023] pzotov
|
||
Since 16.06.2023: output for FB 4.x became identical to FB 5.x, see commit
