ISSUE: 6816
|
|
TITLE: Illegal output length in base64/hex_encode/decode functions
|
|
DESCRIPTION:
|
|
FBTEST: bugs.gh_6816
|
|
NOTES:
|
|
[13.12.2023] pzotov
|
|
Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
|
|
("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
|
|
Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
