Thu Aug 24 06:53:08 EDT 1995 (tim@handel.princeton.edu (Beek))
* raised patchlevel to v21.6b6

be remade due to new config checks
Mon Aug 21 03:18:45 EDT 1995 (tim@handel.princeton.edu (Beek))

func_spec.c, so that the rusage() efun can be included
* added in Deathblade's fixes for remove_call_out()
Thu Aug 3 11:29:56 EDT 1995 (tim@handel.princeton.edu (Beek))
* raised patchlevel to v21.6b3
* added REALLY verbose parsing mode for those really hard to find
parser bugs; use flag > 1 to parse_sentence
* LPC->C fixes:
. fixed a crasher in compilation of control jumps [break, continue]
. fixed an error in adding labels that could write one byte
past the end of the program block
. fixed a syntax error in code for objects using function() {}
. don't generate typechecks after the 4th efun arg
. fixed incorrect argument number in errors from above type checks
. varargs support
. fixed several bugs in foreach handling
. reordered code to fix forward references to functionals when they
occur in global initializers
. fixed continue and break branches for files which generate > 32k
of source
. added alot of prototypes to cfuns.h so LPC->C code compiles more
quietly
. fixed a crasher in __TREE__ { /* something involving foreach */ }
Sun Jul 30 11:11:12 EDT 1995 (tim@handel.princeton.edu (Beek))

callbacks
. fixed a crasher when parse_my_rules tried to return an error
Sat Jul 29 20:12:46 EDT 1995 (tim@handel.princeton.edu (Beek))
* raised patchlevel to v21.6b1
* updated with respect to v21.5
* added next_bit(). next_bit(string str, int foo) returns the
next bit set in str after foo, or -1 if foo is the last one
(str is a set_bit/clear_bit string). For example, to loop over
set bits:
int bit = -1; while ((bit = next_bit(str, bit)) != -1) { ... }
* Added a warning for (: string constant :)
* fixed another crasher in filter_mapping
* fixed crashers in promote_to_float and promote_to_int
* clarified the error message for passing x... to a non-varargs
function
* parser stuff:
. added parser support for 'me' and 'myself'
. fixed 'the' and 'a' support to not inappropriately gobble them
. added a debug mode turned on with an optional flag to
parse_sentence: parse_sentence(foo, 1)
. Added parser support for visibility:
ob->inventory_accessible() can objects inside be used?
ob->inventory_visible() can objects inside be seen?
as usual, they are cached, so call parse_refresh() if they change
. Added extra attributes for tokens; the for is XXX:wxyz
where w, x, y, z are one of:
l - must be living v - need not be accessible (visible only)
so "OBJ:l" is the same as "LIV", and "LIV:v" is someone you can
see.
. fixed a bug introduced in the get_single optimization that
erroneously reported ambiguous parses
. fixed STR to return the original text, not the sanitized version
. the 'verb' passed to verb_* rules are also no longer sanitized
. same with 'real names' of objects
. finished implementing the error messages, including 'There is no
X here'
. optimized STR rules a bit
. fixed a few bugs in finding interpretations with multi-word
tokens
. parse_sentence() can legally be called from do_* callbacks now

classes/arrays/mappings
* fixed a bug that caused 'Inherit chain too deep' errors when
load_object() was called repeatedly on non-existent objects
* fixed the alpha crasher fix (I changed the wrong #ifdef merging
the changes into my local version)
* (: foo :) when foo is both a local function and a simul now gives
a pointer to the lfun, not the simul in line with the normal
visibility rules.
Thu Jul 6 03:29:37 1995 (tim@handel.princeton.edu (Beek))
* raised patchlevel to v21.5b7

F_SHORT_STRING
* Alpha crasher fix: make sure there isn't any padding at the end
of the shared string and malloc'ed string structs so that they
overlap correctly

* raised patchlevel to v21.5b5
* fixed MUD mode sockets to not abort the driver if they can't
allocate enough memory for a packet (due to garbage for the
length field, for example). The connection is killed instead.

Sun Jun 11 04:04:49 EDT 1995 (tim@handel.princeton.edu (Beek))
* raised patchlevel to v21.5b1
* updated with respect to v21.4
* fixed a bunch of warning messages and unsafe casts for DEC Alpha

. call_stack(1) : array of current objects (in that frame)
. call_stack(2) : array of function names
. call_stack(3) : array of what origin() returns in that frame
all the arrays are the same length; i.e. element 5 of call_stack(0)
is the same frame as element 5 of call_stack(2)
e.g. printf("I got called from %s in %s", call_stack(2)[0],
call_stack(0)[0]);

Thu Jun 1 01:52:29 1995 (tim@handel.princeton.edu (Beek))
* raised patchlevel to v21.4b9
* removed a kludge to help older TMI-2 libs run. It was causing
delayed crashers after errors in add_actions(), as well as
screwing up the previous_object(-1) lists. I also think it was
the cause of the unresolved backend crashers around v21 or so.
* COMPAT_BUSTER: due to the above, previous_object() is now zero
in add_action()'ed functions
Mon May 29 21:24:55 1995 (tim@handel.princeton.edu (Beek))

mutate
* fixed a crasher when a socket which had a function pointer as a
callback was closed and then reused
* if a unbound socket is marked as needing a read, print an error
message and close it. This shouldn't ever happen, but evidentally
does and causes the CPU to race
Sat May 27 00:39:07 1995 (tim@handel.princeton.edu (Beek))

* fixed pluralize() to make sure the string is zero terminated
* swapped two include files to prevent a definition of SE in
<sys/sema.h> from overriding one in <arpa/telnet.h>; it causes
terminal negotiation to freeze output to the user
* fixed a bug that caused type errors when inheriting from a
program with #pragma save_types on which was saved as a binary
* upped the default optimization to -O3 on xlc
* fixed a crasher in assigning to indexed strings/array ranges
in LPC->C
* added LPC->C support for parse_command() and evaluate()
* put the O_CLONE flag back on replace_program() objects; makes
memory accounting efuns return slightly more intuitive values
and makes some sense. This means you can't clone from such an
object, but that's probably good since create() isn't what you'd
expect anyway
* fixed a bug that generated illegal LPC->C code if the last case in a
switch was empty (it's legal in LPC but not ANSI C)
* fixed a few typos in LPC->C code generation (i -> lpc_int)
* made the error messages for trying to compile something with a
functional more friendly (LPC->C)

before the preprocessor directive
* cleaned up some more uses of MSTR_SIZE/COUNTED_STRLEN to fix
more bugs with > 64k strings

and clear up some crashers, as well as be a bit more robust/efficient
* cleaned up some gcc -Wall warnings
* include configure.h as well as std_incl.h when testing for existence
of header files. This fixes misconfiguration bugs with respect to
rusage() on some systems (SunOS, ...)
* fixed outbuf_t compilation problems in comm.c on some systems
* fixed a crasher when explode() returned an array that was truncated
due to max_array_size
