Quick SBCL Notes #
hacking, December 12th 2008
Plenty of Hackers: I heard over the grapveine that I am "the last man standing" when it comes to SBCL development. While it is true that I am the most active committer at the moment — which can give the casual eye a wrong impression — my disproportionate number of commits does not mean others are idle: over the last ~9 months 11 different committers have been active. This does not include non-committers who have submitted patches, so the real number is somewhat higher.
Interesting Stuff in CVS: I have just merged two noteworthy patches. One fixes stack allocation by nested structure constructors (bug 430), and is very much worth checking out if you have structures that could be stack allocated. The other addresses some long-standing thread-safety issues in CLOS: most notably now DEFCLASS, ENSURE-CLASS-USING-CLASS, and obsolete instance updating is expected to be thread safe. Bugreports and possible performance regression reports most welcome on sbcl-devel, as ever.
