	Fixed an execution ordering bug which should have caused
	an infinite loop in some weird file blocking cases.
	
	* float.c: (FloatPrint):
	Don't print fractional part if it rounds to zero. Still
	need to trim trailing zeros from fractions.

2004-10-19  Keith Packard  <keithp@keithp.com>

	* examples/mutextest.5c:
	* examples/skiplist.5c:
	* examples/skiplisttest.5c:

2004-07-09  Keith Packard  <keithp@keithp.com>

	* symbol.c: (SymbolLocalMark):
	Missed a few pointers in mark code
	
	* mem.c: (MemInitialize):
	* sched.c: (RaiseException):
	A nasty one -- jumping into a continuation that is referenced
	from the thread object itself (catch) drops the reference to the
	continuation before finishing the jump.  Combined with careful
	MemCollect timing, this can break the resulting thread state.
	
	* stack.c: (StackPush), (StackPop), (StackDrop), (StackReset),
	(StackReturn), (StackElt), (StackCopy), (stackMark):

	* value.h:
	Parallel catch blocks are peers, not nested.  This affects
	how FarJump execution inside them happens; in particular,
	all of the peer catches are unwound before the handler is
	invoked so all jumps from inside use the same NonLocal
	data structure.  Also added yet more debugging to
	continuation execution.

	* gram.y:
	Allow 'enum switch'

2004-06-19  Keith Packard  <keithp@keithp.com>

	* execute.c: (ThreadCall):

	the definition as well.
	
	* sched.c: (do_Thread_list), (TraceFunction), (TraceFrame),
	(TraceIndent), (ContinuationTrace), (RaiseException):
	Clean up continuation debug code to include call trace

	Handle nested & in Lvalues with auto_reference so that &&7 works.
	* gram.y:
	* lex.l:
	* nickle.h:
	* scope.c: (NamespaceLocate):
	Make ** and && work as unary operators.
	Get CodePtr out of CurrentFrame so that execution can
	refer to frame contents up the static link.

2004-06-13  Keith Packard  <keithp@keithp.com>

	* file.5c:
	Don't open /dev/null until needed for mkchild

	to work.

	* update-version.sh:
	Clean up examples so they all work again.  Remove old files.
	add 'scanf' to top-level namespace

2004-05-25  Keith Packard  <keithp@keithp.com>

	* Makefile.am:
	* builtin.c:
	* configure.in:
	Completely ignore VERSION support from configure and grub it
	out of the ChangeLog using $(shell) from the Makefile.

2004-05-25  Keith Packard  <keithp@keithp.com>

	* debian/changelog:
	Add comments for version 2.35

2004-05-25  Keith Packard  <keithp@keithp.com>

	* compile.c: (CompileLvalue), (CompileAssign), (CompileAssignOp),
	(CompileAssignFunc), (CompileArrayInit), (_CompileExpr),
	(CompileDecl):
	Allow &rvalue and have it automatically box the value.

2004-05-21 Bart Massey <bart@cs.pdx.edu>
version 2.34
	
	* version.m4, Makefile.am, make-version.sh

	The version number is going stale again.  Start putting it in the
	ChangeLog, and have the Makefile grub it out of there.  Get rid of
	version.m4 After all, the ChangeLog has to be good for something
	:-).

2004-05-20  Keith Packard  <keithp@keithp.com>

	* compile.c: (CompileLvalue), (_CompileExpr):
	Ok, so the previous change was incomplete.
	
	Restructure CompileLvalue so that the processing of ampersands is
	unified.  The unified rules were changed so that the value of a
	reference to a reference type is converted to a pointer instead of a
	reference.  That seems confusing enough.  Basically, it allows:

		&int r;
		*&int pr = & & r;

2004-05-20  Keith Packard  <keithp@keithp.com>

	* compile.c: (_CompileExpr):
	When compiling '&' expressions, if the operand is of ref type,
	the result type is the referenced type, not NULL.

2004-05-20  Bart Massey  <bart@cs.pdx.edu>

	* gram.y, compile.c pretty.c
	Two-argument for() loop is legal
	now (no init expr).

2004-05-17  Bart Massey  <bart@cs.pdx.edu>

	* parse-args.5c:

	quote contexts using generator functions.

2004-05-13  Bart Massey  <bart@cs.pdx.edu>

	* builtin-toplevel.c:
	* nickle.h:
	Rename is_defined() to is_uninit().

2004-05-12  Bart Massey  <bart@cs.pdx.edu>

	* builtin-toplevel.c:
	* nickle.h:
	Add a predicate is_defined() to test whether a reference
	is to a <uninit> value.

2004-04-23  Keith Packard  <keithp@keithp.com>

	* test/optest.5c:
	* test/orderofoptest.5c:
	Turn each test into an assertion which exits with an
	error on failure so that 'make check' validates the interpreter

2004-04-18  Keith Packard  <keithp@keithp.com>

	* pretty.c: (doPrettyPrint):
	Label profile times in ms
	* profile.c: (sigprofile), (ProfileInterrupt), (do_profile):
	profile tracking code was quite busted, generating largely
	random numbers.

	is stored off the end of the string.

2004-04-16  Bart Massey  <bart@cs.pdx.edu>

	Fixed unclosed string detection case in parse_csv.

2004-04-15  Bart Massey  <bart@cs.pdx.edu>

	* builtin-string.c: (do_String_substr):
	Allow a zero-length substr() at the end of the string.
	
	* string.5c:
	Clean up a bunch of substr() references.  Remove
	accidental redundant code.
	
2004-04-15  Bart Massey  <bart@cs.pdx.edu>

	* file.c: (FilePuts):
	Handle emitting backslash in quoted string properly.
	
2004-04-15  Bart Massey  <bart@cs.pdx.edu>

	* string.5c:
	Added new string functions _dequote(), dequote(), inchars(),
	readcsv(), and associated machinery.
	* builtin.5c:
	String depends on Ctype now, so reordered.

2004-04-15  Keith Packard  <keithp@keithp.com>

	* scope.c: (NamespaceLocate):
	* type.c: (TypeCompatibleAssign):
	* value.c: (CopyMutable):
	* value.h:
	Change resizable array representation to be a vector
	of single entry boxes.  This allows clean semantics
	for array shrinking -- outranged elements still have
	storage, but are no longer accessible through the
	array, even if the array is subsequently enlarged.

	* builtin-file.c: (do_File_filter), (do_File_end),
	(do_File_ungetb):
	Change File::end semantic to actually peek at the file
	and check whether the next read would return EOF.
	This seems like the only useful semantic here.

	* builtin-string.c: (do_String_new):
	Was using ArrayDims instead of ArrayLimits
	
	* builtin.5c:
	white space change

	* compile.c: (AppendObj):
	Must propogate error when appending objects together

2004-04-15  Bart Massey  <bart@cs.pdx.edu>

2004-04-14  Bart Massey  <bart@cs.pdx.edu>

	reviewed by: Keith Packard <keithp@keithp.com>

	* hash.c: (HashGet), (HashSet):
	Make hash table grow when full on get of
	default value.  Clean boundary case in
	test in HashSet.  Keithp really did this.

2004-04-11  Bart Massey  <bart@cs.pdx.edu>

	* string.5c: (split):
	Add split function ala awk.

	Primitive docs for resizable arrays and hashes.

2004-04-10  Keith Packard  <keithp@keithp.com>

	* builtin-toplevel.c: (do_setdims):
	setdims arguments need to be inverted to match array
	dimension order for ArrayResize.

2004-04-10  Keith Packard  <keithp@keithp.com>

	* box.c: (BoxRewrite):
	Ugh.  Array shrink causes problems with references to
	elements now outside the box boundaries.  "real" fix
	is hard, so here's a kludge to keep the interpreter
	from crashing and (perhaps) prevent the error
	from propagating through the application.

	Make value distinction between resizable and unresizable
	arrays.  Types now use '...' for resizable arrays and '*'
	for unresizable arrays of unspecified size.
	
	Also fixed a bug in the implicit array dimension
	computation for multi-dimensional arrays -- the
	dimensions were compiled in the reverse order.
