New draft (#5) of SRFI 168: Generic Tuple Store Database Arthur A. Gleckler 18 Sep 2019 22:59 UTC

I've just published draft #5 of SRFI
168.  It was submitted by Amirouche
Boubekki, author of the SRFI.

  <https://srfi.schemers.org/srfi-168/>

Here are Amirouche's comments on the draft:

  SRFI-167 and SRFI-168 implementation
  were improved but far from perfect.

  The three big changes are in SRFI-167
  and SRFI-168:

  - remove manual transaction management
    (John C. advice)

  - add hooks to both SRFI-167 and
    SRFI-168 to allow things like
    triggers or constraints validation

  - improve and move SRFI-168 engine
    record to its own library inside
    SRFI-167 to allow any layer to make
    use of it.

Here are the commit comments:

  - Generate See also links.
  - implementation: add failing test.
