|
||
|
|
|
||
|
|
Version 1.38
|
||
|
|
Interim release until the rewrite, mostly incorporating modifications
|
||
|
|
from Kevin Cozens. Small addition for Cygwin in the makefile, and
|
||
|
|
modifications by Andrew Guenther for Apple platforms.
|
||
|
|
|
||
|
|
Version 1.37
|
||
|
|
Joe Buehler submitted reserve_cells.
|
||
|
|
|
||
|
|
Version 1.36
|
||
|
|
Joe Buehler fixed a patch in the allocator.
|
||
|
|
Alexander Shendi moved the comment handling in the scanner, which
|
||
|
|
fixed an obscure bug for which Mike E had provided a patch as well.
|
||
|
|
Kevin Cozens has submitted some fixes and modifications which have
|
||
|
|
not been incorporated yet in their entirety.
|
||
|
|
|
||
|
|
Version 1.35
|
||
|
|
Todd Showalter discovered that the number of free cells reported
|
||
|
|
after GC was incorrect, which could also cause unnecessary allocations.
|
||
|
|
|
||
|
|
Version 1.34
|
||
|
|
Long missing version. Lots of bugfixes have accumulated in my email, so
|
||
|
|
I had to start using them. In this version, Keenan Pepper has submitted
|
||
|
|
a bugfix for the string comparison library procedure, Wouter Boeke
|
||
|
|
modified some code that was casting to the wrong type and crashed on
|
||
|
|
some machines, "SheppardCo" submitted a replacement "modulo" code and
|
||
|
|
Scott Fenton submitted lots of corrections that shut up some compiler
|
||
|
|
warnings. Brian Maher submitted instructions on how to build on OS-X.
|
||
|
|
I have to dig deeper into my mailbox and find earlier emails, too.
|
||
|
|
|
||
|
|
Version 1.33
|
||
|
|
Charles Hayden fixed a nasty GC bug of the new stack frame, while in
|
||
|
|
the process of porting TinyScheme to C++. He also submitted other
|
||
|
|
changes, and other people also had comments or requests, but the GC
|
||
|
|
bug was so important that this version is put through the door to
|
||
|
|
correct it.
|
||
|
|
|
||
|
|
Version 1.32
|
||
|
|
Stephen Gildea put some quality time on TinyScheme again, and made
|
||
|
|
a whole lot of changes to the interpreter that made it noticeably
|
||
|
|
faster.
|
||
|
|
|
||
|
|
Version 1.31
|
||
|
|
Patches to the hastily-done version 1.30. Stephen Gildea fixed
|
||
|
|
some things done wrongly, and Richard Russo fixed the makefile
|
||
|
|
for building on Windows. Property lists (heritage from MiniScheme)
|
||
|
|
are now optional and have disappeared from the interface. They
|
||
|
|
should be considered as deprecated.
|
||
|
|
|
||
|
|
Version 1.30
|
||
|
|
After many months, I followed Preston Bannister's advice of
|
||
|
|
using macros and a single source text to keep the enums and the
|
||
|
|
dispatch table in sync, and I used his contributed "opdefines.h".
|
||
|
|
Timothy Downs contributed a helpful function, "scheme_call".
|
||
|
|
Stephen Gildea contributed new versions of the makefile and
|
||
|
|
practically all other sources. He created a built-in STRING-APPEND,
|
||
|
|
and fixed a lot of other bugs.
|
||
|
|
Ruhi Bloodworth reported fixes necessary for OS X and a small
|
||
|
|
bug in dynload.c.
|
||
|
|
|
||
|
|
Version 1.29
|
||
|
|
The previous version contained a lot of corrections, but there
|
||
|
|
were a lot more that still wait on a sheet of paper lost in a
|
||
|
|
carton someplace after my house move... Manuel Heras-Gilsanz
|
||
|
|
noticed this and resent his own contribution, which relies on
|
||
|
|
another bugfix that v.1.28 was missing: a problem with string
|
||
|
|
output, that this version fixes. I hope other people will take
|
||
|
|
the time to resend their contributions, if they didn't make it
|
||
|
|
to v.1.28.
|
||
|
|
|
||
|
|
Version 1.28
|
||
|
|
Many people have contacted me with bugfixes or remarks in
|
||
|
|
the three months I was inactive. A lot of them spotted that
|
||
|
|
scheme_deinit crashed while reporting gc results. They suggested
|
||
|
|
that sc->outport be set to NIL in scheme_deinit, which I did.
|
||
|
|
Dennis Taylor remarked that OP_VALUEPRINT reset sc->value instead
|
||
|
|
of preserving it. He submitted a modification which I adopted
|
||
|
|
partially. David Hovemeyer sent me many little changes, that you
|
||
|
|
will find in version 1.28, and Patrice Stoessel modified the
|
||
|
|
float reader to conform to R5RS.
|
||
|
|
|
||
|
|
Version 1.27
|
||
|
|
Version 1.27 is the successor of 1.25. Bug fixes only, but I had to
|
||
|
|
release them so that everybody can profit. 'Backchar' tried to write
|
||
|
|
back to the string, which obviously didn't work for const strings.
|
||
|
|
'Substring' didn't check for crossed start and end indices. Defines
|
||
|
|
changed to restore the ability to compile under MSVC.
|
||
|
|
|
||
|
|
Version 1.26
|
||
|
|
Version 1.26 was never released. I changed a lot of things, in fact
|
||
|
|
too much, even the garbage collector, and hell broke loose. I'll
|
||
|
|
try a more gradual approach next time.
|
||
|
|
|
||
|
|
Version 1.25
|
||
|
|
Types have been homogenized to be able to accommodate a different
|
||
|
|
representation. Plus, promises are no longer closures. Unfortunately,
|
||
|
|
I discovered that continuations and force/delay do not pass the SCM
|
||
|
|
test (and never did)... However, on the bright side, what little
|
||
|
|
modifications I did had a large impact on the footprint:
|
||
|
|
USE_NO_FEATURES now produces an object file of 63960 bytes on Linux!
|
||
|
|
|
||
|
|
Version 1.24
|
||
|
|
SCM tests now pass again after change in atom2str.
|
||
|
|
|
||
|
|
Version 1.23
|
||
|
|
Finally I managed to mess it up with my version control. Version
|
||
|
|
1.22 actually lacked some of the things I have been fixing in the
|
||
|
|
meantime. This should be considered as a complete replacement for
|
||
|
|
1.22.
|
||
|
|
|
||
|
|
Version 1.22
|
||
|
|
The new ports had a bug in LOAD. MK_CLOSURE is introduced.
|
||
|
|
Shawn Wagner inquired about string->number and number->string.
|
||
|
|
I added string->atom and atom->string and defined the number
|
||
|
|
functions from them. Doing that, I fixed WRITE applied to symbols
|
||
|
|
(it didn't quote them). Unfortunately, minimum build is now
|
||
|
|
slightly larger than 64k... I postpone action because Jason's idea
|
||
|
|
might solve it elegantly.
|
||
|
|
|
||
|
|
Version 1.21
|
||
|
|
Jason Felice submitted a radically different datatype representation
|
||
|
|
which he had implemented. While discussing its pros and cons, it
|
||
|
|
became apparent that the current implementation of ports suffered
|
||
|
|
from a grave fault: ports were not garbage-collected. I changed the
|
||
|
|
ports to be heap-allocated, which enabled the use of string ports
|
||
|
|
for loading. Jason also fixed errors in the garbage collection of
|
||
|
|
vectors. USE_VERBATIM is gone. "ssp_compiler.c" has a better solution
|
||
|
|
on HTML generation. A bug involving backslash notation in strings
|
||
|
|
has been fixed. '-c' flag now executes next argument as a stream of
|
||
|
|
Scheme commands. Foreign functions are now also heap allocated,
|
||
|
|
and scheme_define is used to define everything.
|
||
|
|
|
||
|
|
Version 1.20
|
||
|
|
Tracing has been added. The toplevel loop has been slightly
|
||
|
|
rearranged. Backquote reading for vector templates has been
|
||
|
|
sanitized. Symbol interning is now correct. Arithmetic functions
|
||
|
|
have been corrected. APPLY, MAP, FOR-EACH, numeric comparison
|
||
|
|
functions fixed. String reader/writer understands \xAA notation.
|
||
|
|
|
||
|
|
Version 1.19
|
||
|
|
Carriage Return now delimits identifiers. DOS-formatted Scheme files
|
||
|
|
can be used by Unix. Random number generator added to library.
|
||
|
|
Fixed some glitches of the new type-checking scheme. Fixed erroneous
|
||
|
|
(append '() 'a) behavior. Will continue with r4rstest.scm to
|
||
|
|
fix errors.
|
||
|
|
|
||
|
|
Version 1.18
|
||
|
|
The FFI has been extended. USE_VERBOSE_GC has gone. Anyone wanting
|
||
|
|
the same functionality can put (gcverbose #t) in init.scm.
|
||
|
|
print-width was removed, along with three corresponding op-codes.
|
||
|
|
Extended character constants with ASCII names were added.
|
||
|
|
mk_counted_string paves the way for full support of binary strings.
|
||
|
|
As much as possible of the type-checking chores were delegated
|
||
|
|
to the inner loop, thus reducing the code size to less than 4200 loc!
|
||
|
|
|
||
|
|
Version 1.17
|
||
|
|
Dynamically-loaded extensions are more fully integrated.
|
||
|
|
TinyScheme is now distributed under the BSD open-source license.
|
||
|
|
|
||
|
|
Version 1.16
|
||
|
|
Dynamically-loaded extensions introduced (USE_DL).
|
||
|
|
Santeri Paavolainen found a race condition: When a cons is executed,
|
||
|
|
and each of the two arguments is a constructing function, GC could
|
||
|
|
happen before all arguments are evaluated and cons() is called, and
|
||
|
|
the evaluated arguments would all be reclaimed!
|
||
|
|
Fortunately, such a case was rare in the code, although it is
|
||
|
|
a pitfall in new code and code in foreign functions. Currently, only
|
||
|
|
one such case remains, when COLON_HOOK is defined.
|
||
|
|
|
||
|
|
Version 1.15
|
||
|
|
David Gould also contributed some changes that speed up operation.
|
||
|
|
Kirk Zurell fixed HASPROP.
|
||
|
|
The Garbage Collection didn't collect all the garbage...fixed.
|
||
|
|
|
||
|
|
Version 1.14
|
||
|
|
Unfortunately, after Andre fixed the GC it became obvious that the
|
||
|
|
algorithm was too slow... Fortunately, David Gould found a way to
|
||
|
|
speed it up.
|
||
|
|
|
||
|
|
Version 1.13
|
||
|
|
Silly bug involving division by zero resolved by Roland Kaufman.
|
||
|
|
Macintoch support from Shmulik Regev.

|
||
|
|
EXPT now has correct definition. Added FLOOR,CEILING,TRUNCATE
|
||
|
|
and ROUND, courtesy of Bengt Kleberg. Preprocessor symbols now
|
||
|
|
have values 1 or 0, and can be set as compiler defines (proposed
|
||
|
|
by Andy Ganor *months* ago). 'prompt' and 'InitFile' can now be
|
||
|
|
defined during compilation, too.
|
||
|
|
|
||
|
|
Version 1.10
|
||
|
|
Another bug when file ends with comment!
|
||
|
