sterni 3398c2ab7f fix(3p/lisp/mime4cl): don't store redundant headers in MIME-MESSAGE 
MIME-MESSAGE has a HEADERS slot which is an alist of all headers. Some
of those headers will be parsed again and stored in MIME-PART (or a
subclass of it). Having the header content stored in the HEADERS alist
and in MIME-PART causes problems:

- Requires extra knowledge about how messages are parsed when rendering
  messages.
- Makes MIME= depend on the specific whitespace and quoting in those
  headers which isn't preserved by how mime4cl parses e.g. Content-Type.
- Gives users two ways that slightly diverge to access the same thing.

To avoid this, we remove these headers after the MIME-PARTs contained in
MIME-MESSAGE have been initialized (since they reuse the HEADERS slot).

mime4cl

MIME4CL is a Common Lisp library for dealing with MIME messages. It was originally been written by Walter C. Pelissero and vendored into depot (mime4cl-20150207T211851.tbz to be exact) as upstream has become inactive. Its original website can still be accessed.

The depot version has since diverged from upstream. Main aims were to improve performance and reduce code size by relying on third party libraries like flexi-streams. It is planned to improve encoding handling in the long term. Currently, the library is being worked on intermittently and not very well tested—it may not work as expected.

Differences from the original version

  • //nix/buildLisp is used as the build system. ASDF is currently untested and may be broken.

  • The dependency on sclf has been eliminated by inlining the relevant parts.

  • MY-STRING-INPUT-STREAM, DELIMITED-INPUT-STREAM, CHARACTER-INPUT-ADAPTER-STREAM, BINARY-INPUT-ADAPTER-STREAM etc. have been replaced by (thin wrappers around) flexi-streams. In addition to improved handling of encodings, this allows using READ-SEQUENCE via the gray stream interface.
