    	More pathname fun, *sigh*
    	... make logical pathnames respect print/read consistency (version
    		*is* significant for them)
    	... adjust the pathname tests so that they test equality rather
    		than namestring equality, but minus version testing
    		because that's too complicated right now.

    	Fix some OPEN tests

    		default being :CREATE
    	... adjust filesys test to cope with new disallowed
    	... we still fail some OPEN tests in PFD's suite: some are because
    		of not supporting (unsigned-byte 33) streams, while the
    		rest are because DIRECTORY is broken on logical pathnames,

    	RIP (physical) PATHNAME-VERSION significance
    	... remove all internal discrimination based on the version
    		field if the pathname involved has the Unix host.
    	... parsing of a physical pathname namestring (i.e. again either
    		explicitly or implicitly on the Unix host) never produces
    		a version from the namestring.
    	... make :if-exists :new-version behave like :if-exists :error,
    		because despite weasel-words in CLHS someone might
    		legitimately expect :if-exists :new-version not to
    		clobber the old version.
    	... (this latter needs to be revisited, when OPEN is made aware
    		of logical pathnames and the wacky logic they impose; we
    		can support :new-version with LPNs, but only if OPEN is
    	... make pathnames more likely to be read/print consistent, by
    		throwing errors in more cases (we now pass PFD's test for
    		that, not that it's that stringent).
    	... throw errors on use of (:absolute :up) and friends in CL
    		operators, but...
    	... don't throw error on creation, and in fact test in sb-posix
    		that we can use #p"/../" for what it means.

    	Fix for PEEK-CHAR: whitespace means "according to the
    	readtable", not "static list of characters"
    	... but that's complicated for efficiency: we need WHITESPACEP
    		defined before peek-char so that it can be expanded

    	Some essential-for-my-comprehension purify and gencgc
    	refactoring.  Some functional changes too, though none that
    	seem to make any difference in practice
    	Ripped out vast swathes of "is this a large object" checking
    	in gencgc's allocation routines.  Now the only criterion for
    	whether an object is handled as a large object is whether its
    	size exceeds the large object threshold.
    	Fixed bug in gc_find_freeish_pages that was causing lots of
    	fragmentation: allocation regions for small objects may now
    	start on the same page as previously closed regions with the
    	same characteristics
    	Fixed rarely-observed bug in gencgc_pickup_dynamic so that it
    	doesn't create a single xMb region from the whole of dynamic
    	space when a core is loaded, instead splitting the space into
    	as many regions as it can (this may be related to bug 95,
    	though I don't /really/ want to claim I fixed that until I see
    	better what the problem is there).  Unless you save unpurified
    	cores you're unlikely to be bitten by this often.
    	New newspace_alloc routine in purify.c makes it all a bit
    	easier to see what's going on there.
    	Replace all hand-coded memory-copying loops with memcpy(); the
    	compiler should be able to optimize this better than we can
    	(actually makes no difference that I can detect to execution
    	time, but the code is now shorter)

    	Quiet.  Too quiet.  Fix bug in pprinting backquotes, introduced

    	... we need to print once to a string stream, to look at the
    		first character to make sure that it's not a @ or a .

    		stream (which is at a different logical block position)

    	At the request of the type system's most heavy user...
    	... refactor NEGATION-TYPEs
    	... make NEGATE an operation in TYPE-CLASS
    	... define type methods for :NEGATE, replacing one god-awful

    	... replace too many uses of
    		(specifier-type `(not ,(type-specifier foo)))
    		with (type-negation foo)
    	We pass as many tests as we used to (both here and in PFD's suite)
    	and we now go faster than we did before 0.8.6 on PFD's random
    	tester.  Sounds good to me.
    	(This was initially part I of a two part refactor.  This stage
    	turns out to be enough for now; if it hadn't been, it should be
    	possible to achieve even greater speed by changing the representation
    	of CONS types to include not just CAR and CDR types but also
    	their negations; then operations on CONS types such as UNION and NEGATE
    	would be much much faster, at a slight cost in initialization).
Something went wrong with that request. Please try again.
