- Sat Feb 29 11:46:07 1992 Steve Byrne (sbb at thehouse)
-
- * Fixed Makefile bug so all READLINE location definitions come from Makefile
- instead of some being in ymakefile
-
- * Fixed several compilation errors with GCC (type mismatches), including
- ymakefile apostrophes in comments.
-
- * Updated the mst.tab.[ch] files to be built from Bison 1.14 -- fixes the
- alloca warning.
-
- * Fixed startup code so that the oop table isn't operated on before it's
- allocated -- believed to cause immediate startup problems on some machines
- (DS 3100)
-
- * Adjusted STIX's Makefile & mstcint.c to have the same DLD support that the
- main directory has.
-
- * Fixed STIX to try to do proper Xau style authentication -- now use
- Server class>>connectToDisplay to connect -- uses the DISPLAY environment
- variable too!
-
- * Switched stix/CFuncs.st to not load Point and Rectangle, as these are the job
- of X.st.
-
- * Added String>>asInteger as a stop-gap -- a better (more comprehensive version
- is in the works).
-
- * Added String>>asByteArray.
-
- * Added a large number of IO routines to UnixStream for reading and writing
- scalar datatypes such as shorts or doubles.
-
- * Released 1.2 for limited distribution a week ago
-
- * Lots of changes
-
- Tue Dec 31 22:51:06 1991 Steve Byrne (sbb at thehouse)
-
- * Added C callin support (finally!!!)
-
- * Added registry of Smalltalk objects passed out to C so that the GC doesn't
- remove things while C isn't looking
-
- Mon Dec 30 19:22:06 1991 Steve Byrne (sbb at thehouse)
-
- * Added browsing of all implementations of a given selector.
-
- * Also, finally enabled the full path name recording (code was there, but
- wasn't turned on)
-
- Sun Dec 29 17:18:04 1991 Steve Byrne (sbb at thehouse)
-
- * Added support for readline conditional key bindings, keyed off of "Smalltalk"
-
- Sun Oct 20 19:04:04 1991 Steve Byrne (sbb at laplace)
-
- * added support for user level control of semispace growth parameters
-
- Sat Oct 19 23:45:36 1991 Steve Byrne (sbb at laplace)
-

-
- Sat Oct 5 10:11:20 1991 Steve Byrne (sbb at laplace)
-
- * Added FileStream>>require:
-
- Sun Sep 15 00:36:17 1991 Steve Byrne (sbb at laplace)
-
- * Expanded the number of bits in method headers for primitives, temporaries,
- and literals.
-

- the time of the save.
-
- Sun Jul 28 20:50:04 1991 Steve Byrne (sbb at laplace)
-
- * Performance on fast benchmark now at 860K bytecodes/sec !!!
-
- * Switched to non-incremental GC, also switched OOP table GC to be
- non-incremental.
-
- * Fixed a number of #= methods to check the class of the argument for equality
- with the receiver's class
-
- * enabled use of registers for IP and SP in interpret(). Increased performance
- from 579K/sec to 860K/sec.
-
- * measured min memory size. Kernel alone can be loaded with semi-space sizes
- of 512K, stix needs 1M (really, just over 512K).
-
- * Added in DLD support, enableable via uncommenting Makefile line. Need GNU
- DLD (Dynamic loading) package (not supplied).
-
- Wed Jul 10 12:09:07 1991 Steve Byrne (sbb at laplace)
-
- * Fixed Point.st and Rectangle to have methods #hash and #= so they they can be
- stored in Dictionary's properly.
-
- Thu Jul 5 15:25:07 1991 Steve Byrne (sbb at laplace)
-
- * Added fast string replacement primitives
-
- * Fixed notions of source text for emacs doIt and compile method, so that
- error messages are accurate, and the information about the starting location
- of the text of a method is correct.
-
- Tue Jul 2 21:25:00 1991 Steve Byrne (sbb at laplace)
-
- * Fixed interpretation of conditional jump bytecodes to ensure that the
- value on the stack that they were using was either true or false, and issue
- an error if some other value was on the stack.
-
- Thu Jun 6 21:30:23 1991 Steve Byrne (sbb at laplace)
-
- * Made return (^) expression optionally terminated by a dot
-
- * Added emacs key bindings for manipulating tracing flags
-
- * Fixed Smalltalk Interactor mode ("shell mode") so that it inherits the key
- bindings from normal Smalltalk mode, with the simple additions to make it
- operate like shell mode.
-
- * Delay class implemented and operating nominally
-
- Fri Apr 19 20:48:06 1991 Steve Byrne (sbb at laplace)
-
- * Generalized lexer to handle arbitrary binary operators.
-
- * Added support for lisp-like features (used for conditional
- execution/compilation, among other things)
-
- * Added conditional compilation (methodsFor:ifTrue:)
-
- Mon Mar 25 22:38:48 1991 Steve Byrne (sbb at laplace)
-
- * Added support for the -> operator
-
- * Fixed floating point printing -- now has limits on number of fraction digits,
- and prints very large numbers properly.
-
- Sun Mar 24 02:47:39 1991 Steve Byrne (sbb at laplace)
-
- * Fixed lexer to see foo:= as foo :=
-
- * Fixed lexer bug dealing with 2 character pushbacks when reading from
- strings. ( 'foo _ 1. 3 + foo printNl' I think would tickle it)
-
- * Improved performance by another 50% (up to 328K bytes/sec SS1+ opt)
-
- * Added more Fraction changes (changes.st) for better behavior
-
- Sat Mar 23 02:22:24 1991 Steve Byrne (sbb at laplace)
-
- * Fixed a bug in process switching: after a GC flip, if a context switch
- happened soon after the switch, the process might vanish without a trace.
-
- Sat Mar 16 12:23:04 1991 Steve Byrne (sbb at laplace)
-
- * Implemented Delay class operations
-
- * Implemented Processor signal: atMilliseconds.
-
- * Fixed all kernel classes to have the class creation statement be a separate
- expression from the comment setting expression.
-
- * Implemented C interrupt handling for Smalltalk methods.
-
- Sat Feb 16 11:06:29 1991 Steve Byrne (sbb at laplace)
-
- * Fixed a bug in Dictionary.st -- Dictionary class>>new was being inherited
- from the definition in builtins, which created only Dictionary instances.
- Subclasses of Dictionary would get instances of Dictionary when they invoked
- #new instead of instances of their class.
-
- Mon Feb 4 09:59:51 1991 Steve Byrne (sbb at laplace)
-
- * Fixed bug in String.st -- two fileName methods instead of fileName and then
- filePos
-
- Sun Jan 20 21:58:48 1991 Steve Byrne (sbb at laplace)
-
- * Updated st.el (smalltalk-newline-and-indent) to account for the
- change of current-column in 18.56.
-
- Tue Dec 4 19:22:06 1990 Steve Byrne
-
- * Adjusted the grammar so that the null program is allowed (it's
- no longer a parse error to exit via ^D without entering any
- expressions or method definitions).
-
-
- Sat Nov 17 07:21:40 1990 Steve Byrne
-
- * Moved UnixStream into the standard set of loaded files.
-
- * Updated mstcint to support UnixStream primitives and added
- byteArrayOut support.
-
-
- Sat Nov 10 13:45:06 1990 Steve Byrne
-
- * Behavior>>compile: now returns the method that it just compiled.
-
- * Implemented Behavior>>compile:notifying:, and ClassDescription>>
- compile:classified: and compile:classified:notifying:.
-
-
- Tue Nov 6 19:47:26 1990 Steve Byrne
-
- * defined the ~/.stpre file which is loaded before the image is
- saved. This allows the user to build certain modules into the saved
- image, or perform other initializations that should be saved in
- the image.
-
- Fri Nov 2 20:30:00 1990 Steve Byrne
-
- * Fixed st.el to allow arguments to be specified when invoking
- the Smalltalk process from the interactor.
-
-
- Thu Nov 1 12:00:00 1990 Steve Byrne
-
- * Fixed Behavior>>isBytes to return true only if its not pointers and
- not words.
-
- Tue Oct 2 22:00:24 1990 Steve Byrne
-
- * Fixed binary image file location semantics so that the system won't
- load a binary image file using the default path if there is a kernel
- file in the current directory (this fixes the stix image problem).
-
- Fri Sep 20 21:44:52 1990 Steve Byrne
-
- * After re-reading the blue book, it seems that printOn: should print
- strings with apostrophe's around them. This percolated throughout
- the rest of the system. Also, the print methods for a number of the
- collection classes were altered to be more in line with standard
- Smalltalk.
-
- * allSubclassesDo: was changed to operate for all direct and indirect
- subclasses; previously it was only using the direct ones.
-
- * instVarNames was fixed, allInstVarNames and subclassInstVarNames
- were added.
-
- * Backtracing now prints out the actual class the method was found
- in as well as the receiver's class. Also, blocks are printed
- properly.
-
- Wed May 23 19:09:12 1990 Steve Byrne
-
- * Version 1.1 nearing release
-
- * Dictionary.st: Fixed Dictionary size to return a real value. It was
- returning 0.
- Fixed Dictionary grow to preserve assocations instead of creating new
- ones.
- Fixed Dictionary at:ifAbsent: to deal more gracefully with the failure
- case.
-
- * Float.st: fixed float to contain asFloat
-
- * builtins.st: added builtin sqrt
-
- * mstsave.c: fixed binary image save to save proper amount of storage,
- instead of all blocks and methods ... also fixed full GC to clear out
- oop table after copying fined binary image save to save only a subset
- of the object table that's in use instead of the whole things. This
- change along with the OOP table gc, caused a reduction from 2.5M in
- image file size to 318K.
-
- * mstcomp.c: fixed mstcomp to not divide by zero when reporting cache
- hits or elapsed time.
- fixed to deal with error recovery better. The byte code system was
- being left in an inconsistent state, which was causing great lossage
- after errors.
-
- * mstmain.c: fixed usage of quietExecution in mstmain.c...was not being
- set under certain circumstances
- added support for short file names (SysV 14 char limit)
- added new flags -c, -q, -p, -I.
-
- * Makefile,config.mst: fixed Makefile and config system to be more like
- normal GNU tools.
-
- * mstinterp.c Fixed primitive file open for FileStream to report errors
- when it can't open the file.
- Fixed general C-to-method (executeStatements) behavior. Wasn't
- preserving the caller's stack pointer properly, and so after executing
- a number of top level statements, the return value would trash the
- middle of the top level context, causing lossage.
-
- * Object.st: Fixed object dependencies to use IdentityDictionary
- instead of Dictionary. This not only is faster, but is also more
- correct.
-
- * mstcint.c: added ByteArray type to set of exported types
-
- * Time.st: Fixed printOn: to print the value of the instance variable
- instead of printing "Time now".
-
- * mstoop.c: fixed GC symbol table...wasn't completing scan at GC flip
- time. Also, new symbols weren't making sure that the previous hash
- bucket head was in new-space, which caused lossage.
-
- * mstinterp.c: added verboseTracing: to trace stack top during
- execution tracing.
- Added ^C handling to terminate execution.
-
- * mstcomp.c,mst.y: Fixed to not try to execute if errors are
- encountered during compilation.
-
- * ./stix: added STIX environment
-
- * st.el: created Smalltalk interactor mode.
-
- * added readline interface to provide command line editing and history.
-
- * mst.texinfo: fixed some bugs in the texinfo file
-
- * mstinterp.c,ProcessorScheduler.st,Processor.st:
- Fixed so that terminateActive message works for the current process
- and so that random processes laying around don't reference random
- storage.
-
- * WriteStream.st: fix so that the contents message returns just
- the contents that have been written, not the junk at the end
- of the stream.
