[Sbcl-devel] Deadlines, branches, locks

[Nikodemus S. <tsi...@cc...>]

Package locks are looking pretty good. The current (attached) patch is
against 0.8.10.42.

Some API changes since last time:

 * Don't signal package locked errors for DEFPACKAGE.

 * Changed WITH-PACKAGE-LOCKS-IGNORED to WITHOUT-PACKAGE-LOCKS,
   and left implementation unspecified.

 (I have rationales for both of these, but I'll leave that for another
 time.)

Status:

 * Builds, builds contribs, passes regression suite (with CL and
   SB-* packages locked), builds clx, osicat, terminfo, uffi, and
   linedit.

 * Almost builds McCLIM. Some of the problems are nasal demons revealed
   by package locks (binding COMMON-LISP symbols as restarts), some
   are remaining non-deep problems with PCL/package-lock interaction.

Remaining uglies:

 * Deferring of package-lock related erros to runtime is pretty hacky
   right now, and needs to be rewritten to use style analogous to
   program-errors.

 * PCL interns like crazy, which isn't all the nice with package locks.
   Mostly the interning is done in conjunction with FORMAT, so
   replacing (intern (format nil ...) pcl-package) with (format-symbol
   package ...) that also skips locks is probably a happy solution.

Freeze is coming up so... Should I hurry up to clean things up and get it
in, or just put it on a branch? It's a pretty wide and invasive patch, so
my own inclination would be to branch it first.

Cheers,
