Problems with upstream

[informatimago]

This is a pseudo-issue to inform about recent problematic evolution of upstream:

http://git.kpe.io/?p=cl-base64.git;a=summary

git clone http://git.kpe.io/cl-base64.git

Recently, upstream introduced incompatible changes:
The encoder and decoder API has been broken:

• functions named BASE64-STRING-STRING have been renamed to BASE64-STRING-TO-STRING,
• a bug in the creation of the symbols has been introduced by building the symbol name with FORMAT:

> (defmacro define-base64-decoder (hose sink)
>   `(defun ,(intern (format nil "~A-~A-~A-~A" '#:base64 hose '#:to sink))


< (defmacro def-base64-stream-to-* (output-type)
<   `(defun ,(intern (concatenate 'string (symbol-name :base64-stream-to-)
<                                 (symbol-name output-type)))

Which creates functions named |base64-string-to-string| instead of
BASE64-STRING-TO-STRING when *print-case* is set to:downcase (and
possibly with other results with other settings of the global
variables).

Furthermore, the current quicklisp release (2021-06-30), contains an intermediate stage where the bug of interning with format is introduced, but the renaming is not yet (despite the last commit on the upstream dated 2020-09-30).

Hunchentoot uses the old API, ie. is compatible with our version, but not with the current one in quicklisp.

Have fun!
