Version 51, ??, 1997
|
||
|
|
Changed load/use-compiled: searches for .zo files in
|
||
|
|
a "compiled/" subdirectory, and searches for .so/.dll
|
||
|
|
files in (build-path "compiled" (system-library-subpath))
|
||
|
|
Changed load and current-load/default-load-handler: `load'
|
||
|
|
now sets the current-load-relative-directory, so a load
|
||
|
|
handler does not need to set this parameter
|
||
|
|
Added current-load-extension (load-extension handler)
|
||
|
|
Added read-image-from-file procedure
|
||
|
|
Unix images: removed constraint against using stdio before
|
||
|
|
dumps
|
||
|
|
Unix: fixed file-or-directory-permissions for group-based
|
||
|
|
permissions when the group is not the current group (but
|
||
|
|
still includes the user)
|
||
|
|
Windows: fixed directory-exists? et. al for UNC paths
|
||
|
|
Added local-expand-body-expression
|
||
|
|
Added link-exists?
|
||
|
|
Added copy-file
|
||
|
|
Added path-list-string->path-list
|
||
|
|
Added collection-path
|
||
|
|
Changed initial setting of current-library-collection-paths
|
||
|
|
Changed display for symbols containg special characters:
|
||
|
|
the special characters are not escaped (or bar-quoted)
|
||
|
|
Changed write to use the value of (read-accept-bar-quote)
|
||
|
|
for printing symbols containing special charaters; if
|
||
|
|
bar qute reading is off, it is turned off for printing, too.
|
||
|
|
Fixed unit/sig: correctly handles syntax where defintions in
|
||
|
|
the unit shadow syntactic forms
|
||
|
|
Fixed round of exact rational n/d in the case when (odd? d)
|
||
|
|
and (= (remainder n d) (quotient d 2))
|
||
|
|
Extended exp, sin, cos, tan, log, asin, acons, atan to
|
||
|
|
complex numbers; changed sqrt to choose the root with a
|
||
|
|
positive real part
|
||
|
|
Removed rectangular <, >, <=, >= for complex numbers
|
||
|
|
Changed storage of loaded-library table from built into the
|
||
|
|
`require-library' procedure to built into the current
|
||
|
|
namespace
|
||
|
|
Added require-relative-library
|
||
|
|
Fixed error messages for +, -, etc. to show all arguments
|
||
|
|
Changed MzLib's pconver.ss libraries; the print-convert-hook@
|
||
|
|
unit was removed (along with the pchookr.ss library) and
|
||
|
|
replaced with parameters defined in pconverr.ss for similar
|
||
|
|
(more powerful) hooks.
|
||
|
|
Fixed interfaces for compiled-file (.zo) loading across
|
||
|
|
MzScheme startups
|
||
|
|
Unused interned symbols are now garbage-collected
|
||
|
|
Added support for single-precision floating points (turned
|
||
|
|
off in default compilation)
|
||
|
|
Changed read-eval-print-loop, removing its cooperation with
|
||
|
|
the default error escape handler; instead, it installs its
|
||
|
|
own error escape handler
|
||
|
|
Improved the support for dynamic extensions that gives an
|
||
|
|
error if an extension is already loaded, or calls a
|
||
|
|
reloading function provided by the extension
|
||
|
|
|
||
|
|
Version 50, August 26, 1997
|
||
|
|
Added compile-time inferrence of names for closures, classes,
|
||
|
|
and units to improve error messages
|
||
|
|
Added inferred-name
|
||
|
|
Added file-size
|
||
|
|
Added write-image-to-file for creating heap images of a
|
||
|
|
MzScheme program
|
||
|
|
Fixed reader to disallow . in vectors: #(1 . 2) or #(1 . (3))
|
||
|
|
Removed global-defined-signature
|
||
|
|
Fixed string->number: explicit radix in string can override
|
||
|
|
radix argument
|
||
|
|
Bug fixed in call/cc related to dynamic-wind (see !!! in
|
||
|
|
tests/basic.ss)
|
||
|
|
Fixed weak hash table's accumulation of hashing buckets
|
||
|
|

||
|
|
Added two-argument form for global-defined-value
|
||
|
|

|
||
|
|
or evaluated expression returns an error without the rep
|
||
|
|
Refined error messages
|
||
|
|
|
||
|
|
Version 49, May 31, 1997
|
||
|
|
Multiple superclass inheritance is no longer supported
|
||
|
|
Added (Java-ish) interfaces to object system
|
||
|
|
class* syntax changed to accomodate interfaces and removed
|
||
|
|
multiple superclasses
|
||
|
|
uq-ivar always takes two arguments; class is not a legal argument
|
||
|
|
uq-make-generic accepts a class or an interface
|
||
|
|
Object system exceptions changed
|
||
|
|
Added custodian system
|
||
|
|
Embedded define conventions changed: "regular" defines are only
|
||
|
|
allowed in begin expressions and the branches of an if;
|
||
|
|
embedded defines can appear in a begin0 expression, but not
|
||
|
|
in the first position; defines must all appear at the beginning
|
||
|
|
of the block
|
||
|
|
Contents of a begin expression as an immediate unit or unit/sig
|
||
|
|
expression are promoted to immediate expressions
|
||
|
|
case supports only R4RS syntax; a single non-list "datum" is
|
||
|
|
no longer allowed
|
||
|
|
Removed catch; use let/ec instead
|
||
|
|
Removed vector-append
|
||
|
|
Removed load-with-cd (use load/cd)
|
||
|
|
Added load/use-compiled
|
||
|
|
Added current-load-directory parameter (set by the default load
|
||
|
|
handler while loading a file) and load-relative (uses the
|
||
|
|
parameter for loading a relative filename)
|
||
|
|
unit/sig's include form is like load-relative instead of load/cd
|
||
|
|
require-library uses load or load/use-compiled instead of load/cd
|
||
|
|
Windows: expand-path does not put a drive on a driveless path
|
||
|
|
anymore; use path->complete-path instead
|
||
|
|
compile-file moved out of MzScheme into MzLib "compile.ss"; now
|
||
|
|
takes a single flag list argument instead of two final Booleans
|
||
|
|
current-base-parameterization parameter replaced with
|
||
|
|
parameterization-branch-handler parameter
|
||
|
|
Parameterizations support sharing (in addition to defaulting);
|
||
|
|
see docs for make-parameterization-with-sharing
|
||
|
|
Added print, port print handlers, and a global port print handler
|
||
|
|
Changed the default print handler to use print instead of write
|
||
|
|
Fixed bug in ports returned by make-pipe
|
||
|
|
Fixed bug in dynamic-wind; continuation jumps into the pre-thunk
|
||
|
|
had a non-intuitive semantics; the correct semantics is now
|
||
|
|
implemented and documented (also for jumps with the post-thunk)
|
||
|
|
Changed time-apply to always return a list as its first return
|
||
|
|
value; time form can return multiple values for its expressions
|
||
|
|
format, fprintf, and printf are case-insensitive for ~ directives;
|
||
|
|
added ~v, ~e, ~<whitespace>
|
||
|
|
Added semaphore-wait/enable-break
|
||
|
|
Added thread-running? and thread-wait
|
||
|
|
Fixed bug in threads and timed sleeping
|
||
|
|
Fixed bug in breaking a blocked thread
|
||
|
|
Fixed bug in continuations returning multiple values through a
|
||
|
|
dynamic-wind (multiple return values could be corrupted)
|
||
|
|
Fixed arity reporting for continuations
|
||
|
|
Fixed Windows system* and read from console stdin and process*
|
||
|
|
ports: MzScheme threads no longer blocked; ctl-c breaking works
|
||
|
|
in stand-alone console MzScheme
|
||
|
|
process and process* now return a list of 5 values (instead of 4)
|
||
|
|
map, for-each, andmap, and ormap raise exn:application:map-arity
|
||
|
|
when the procedure's arity does not match the number of supplied
|
||
|
|
lists; note that (map (lambda () 10) null) now signals an error
|
||
|
|
list-ref and list-tail accept arbitrarily large indices
|
||
|
|
Type for indices changed: must be an exact integer (matches R4RS better)
|
||
|
|
affects make-vector, vector-ref, vector-set!, make-string, string-ref,
|
||
|
|
string-set!, substring, and struct-ref
|
||
|
|
make-namespace's '[no-]set!-undefined and '[no-]auto-else flags
|
||
|
|
removed; replaced with two new parameters:
|
||
|
|
compile-allow-set!-undefined and compile-allow-cond-fallthrough
|
||
|
|
Fixed in units: (define x y) (define y 0) x => #<undefined> instead of
|
||
|
|
#<void>
|
||
|
|
exn:struct's super-type field renamed struct-type for consistency
|
||
|
|
exn:i/o:filesystem:filename split into exn:i/o:filesystem:path
|
||
|
|
and exn:i/o:filesystem:file; username exception moved under path
|
||
|
|
Unix: system no longer blocks other MzScheme threads
|
||
|
|
Unix: processes created by process and process* are not zombies forever,
|
||
|
|
anymore. (The SIGCHLD signal is handled appropriately.)
|
||
|
|
MacOS: dynamic extension suopport via CFM (PPC only in the distributed
|
||
|
|
applications from PLT)
|
||
|
|
Windows: removed attempted fix for thread-blocking problem
|
||
|
|
when reading stdin from console
|
||
|

Fixed auto-flush of stdout for read of stdin
|
||
|
|
Fixed <, >, <=, >= for certain exact rational number comparisons
|
||
|

|
was added to the resulting number with the wrong sign)
|
||
|
|
Fixed rational? to answer #t for inexact numbers
|
||
|
|
Fixed odd?, even?, and trig functions for +inf.0 and -inf.0

|
||
|
|
everything under Windows

||
|
|
Library system generalized to supoprt multiple collections;

|
||
|
|
require-library now returns the result of the loaded library
|
||
|
|
Removed load-recent from MzLib's file.ss; use load/use-compiled
|
||
|
|
instead
|
||
|
|
Added reference-library, "refer.ss" [core], "XXXr.ss" MzLib libraries
|
||

|
||
|
|
|
||
|
|
Version 47, January 11, 1997
|
||

|
WARNING: multiple inhertance is going away in the next version or so
|
||
|
|
Added will executors
|
||
|
|
pretty-print-print-hook and pretty-print-size-hook now take
|
||
|
|
three arguments: value display? port
|
||
|
|
file-position can return the current position for any port
|
||
|
|
Fixed errors reading floating-point constants due to system
|
||
|
|
library bugs:
|
||
|
|
Linux: strtod("0e...", ...) quits looking after "0"
|
||
|
|
SunOS/Solaris: strtod(".3e2666666666") returned 0.0

|
||
|
|
Windows: fixed thread-blocking problem for reading stdin from console
|

|
|
Insize MzScheme: when working with "fd_set" values, use
|
||
|
|
MZ_FD_ZERO, MZ_FD_SET, MZ_FD_CLR, MZ_FD_ISSET; use
|
||
|
|
scheme_get_fdset() to get the second or third fd_set in an array;
|
||
|
|
routines for thread-blocking are now documented in "Inside MzScheme"
|
||
|
|
|
||
|
|
Version 46, December 5, 1996
|
||
|
|
unit/sig macros moved out of MzLib and into core MzScheme;
|
||
|
|
(require-library "unitsig.ss") is obsolete, but still supported
|
||
|
|
as a no-op
|
||
|
|
Unit signature matching is now position-independent, and the error
|
||
|
|
messages are better
|
||
|
|
Removed obsolete install-unit-with-signature
|

||
|
|
quasiquote syntax changed slightly
|
||
|

|
Version 45, November 12, 1996
|
||
