|
|
release_notes/release_notes.stex csug/csug.stex
|
|
- added missing include
|
|
killme.c
|
|
- added new mat verifying that primitives raise exceptions for invalid
|
|
arguments based on primdata.ss signatures. fixed some of those
|
|
signatures, which weren't otherwise used except for arity checking.
|
|
fixed some issues turned up by the test with who reports errors
|
|
and how.

primdata.ss, 5_1.ss, 7.ss, compile.ss, cpnanopass.ss, fasl.ss,

|
root-experr*, patch*
|
|
- string comparisons (string=?, string-ci<?, etc.) now get out fast
|
|
when handed eq arguments.
|
|
5_4.ss
|
|
- changed representation of most-negative iptr, I32, and I64 to make
|
|
Visual C compiler happy. updated windows make files, which had
|
|
fallen out of date. added missing hsrc= files sort.h and thread.h
|
|
so they show up in the Windows workarea c directory.
|
|
cmacros.ss,
|
|
fasl.c, number.c, c/Mf-base, c/Makefile.{t,}{i3,a6}nt
|
|
- The scheme.h definition of Sfixnum(x) now uses multiply rather than
|
|
left shift to avoid counting on the behavior of << on negative numbers,
|
|
which is undefined in C.
|
|
mkheader.ss
|
|
- Fixed a couple of casts, one harmless and the other causing
|
|
Sinteger64_value to return 0 for the most-negative I64 on 32-bit
|
|
builds.
|
|
number.c
|
|
- The configure-generated Makefile distclean target no longer removes
|
|
zlib and nanopass, since they are logically part of the git clone.
|
|
It does run make distclean in zlib.
|
|
makefiles/Makefile.in
|
|
- converted s_test_schlib shifts of -1 to equivalent shifts of 1 to
|
|
avoid undefined left-shift behavior on negative numbers.
|
|
prim5.c
|
|
- added if(---) {} wrapper around call to WRITE in display macro to
|
|
silence unused return-value warnings.
|
|
prim5.c
|
|
- liberalized get-mode check for ../mats. it's not our business whether
|
|
people make their directories group and/or other writeable.
|
|
6.ms
|
|
- make test now prints the actual relative path to summary in the
|
|
"check summary" message, whether invoked from the top-level directory
|
|
or from the workarea.
|
|
Makefile.in, Makefile-workarea.in
|
|
- configure now just uses cat to copy Makefile-workarea.in to $w/workarea,
|
|
since the file is presently the same regardless of the configuration.
|
|
configure
|
|
- fixed time-utc->date test in mat time&date-printing to work regardless of
|
|
what locale (and time zone) the host machine has set.
|
|
date.ms
|
|
- fixed date->time-utc to honor the zone-offset field when converting a date
|
|
object to a time-utc object.
|
|
stats.c,
|
|
date.ms
|
|
- fixed incorrect handling of library-extension when searching wpo files
|
|
compile.ss,
|
|
7.ms
|
|
- modified floatify_normalize to properly round denormalized results.
|
|
obviated scale_float in the process.
|
|
number.c,
|
|
ieee.ms
|
|
- fixed 0eNNNN for large NNNN to produce 0.0 rather than infinity
|
|
strnum.ss,
|
|
5_3.ms
|
|
- the reader now raises an exception with condition type implementation
|
|
restriction (among the other usual lexical condition types), and
|
|
string->number now raises #f, for #e<m>@<a>, where <m> and <a> are
|
|
nonzero integers, since Chez Scheme can't represent polar numbers other
|
|
than 0@<n> and <n>@0 exactly. <m>@<a> still produces an inexact result,
|
|
i.e., we're still extending the set of inexact numeric constants beyond
|
|
what R6RS dictates. doing this required a rework of $str->num, which
|
|
turned into a fairly extensive rewrite that fixed up a few other minor
|
|
issues (like r6rs:string->number improperly allowing 1/2e10) and
|
|
eliminated the need for consumers to call $str->num twice in cases
|
|
where it can actually produce a number. added some related new tests,
|
|
including several found missing by profiling. added a couple of
|
|
checks to number->string the absence of which was causing argument
|
|
errors to be reported by other routines.
|
|
strnum.ss, exceptions.ss, read.ss
|
|
5_3.ms, 6.ms, root-experr*, patch*
|
|
- added pdtml flag, which if set to t causes profile-dump-html to be
|
|
called at the end of a mat run.
|
|
mats/Mf-base
|
|
- compile-whole-program and compile-whole-library now copy the hash-bang
|
|
line from the wpo file (if it has one) to the object file.
|
|
compile.ss,
|
|
7.ms
|
|
- stex is now a submodule. csug/Makefile and release_notes/Makefile
|
|
set and use the required Scheme and STEXLIB variables accordingly.
|
|
they default the machine type to a6le, but this can be overridden
|
|
and is by the generated top-level Makefile. the generated top-level
|
|
Makefile now has a new docs target that runs make in both csug and
|
|
release_notes, and an updated distclean target that cleans the same.
|
|
the annoying csug Makefile .fig.pdf rule redefinition is now gone.
|
|
copyright.stex and csug.stex now list May 2016 as the revision month
|
|
and date; this will have to be updated for future releases.
|
|
configure, makefiles/Makefile.in,
|
|
csug/Makefile, copyright.stex, csug.stex,
|
|
release_notes/Makefile
|
|
- added custom install options. workarea creates an empty config.h,
|
|
and configure creates a config.h that sets the default scheme heap
|
|
path and scheme-script name based on the actual configuration.
|
|
configure, newrelease, workarea, checkin,
|
|
c/Mf-base, scheme.c, main.c,
|
|
Mf-install.in
|
|
- renamed the installed example directory from lib to examples.
|
|
Mf-install.in,
|
|
scheme.1.in
|
|
- added force option to gzip during man page install to prevent gzip from
|
|
asking for permission to overwrite existing man page files.
|
|
Mf-install.in
|
|
- removed ~/lib/csv%v/%m from the default scheme heap path on unix-like
|
|
systems. documented inclusion of %x\..\..\boot\%m in the Windows
|
|
default scheme heap path.
|
|
main.c,
|
|
use.stex
|
|
- added new configuration options: --installbin, --installlib,
|
|
--installschemename, --installpetitename, and --installscriptname.
|
|
configure
|
|
- updated the example library link to the nanopass framework.
|
|
CONTRIBUTING.md
|
|
- now cleaning up petite.1 and scheme.1 left behind by make install
|
|
Makefile-workarea.in, checkin
|
|
- now removing workarea after cleaning csug and release_notes so
|
|
Mf-stex (included from csug/Makefile and release_notes/Makefile)
|
|
doesn't complain trying to determine the machine type.
|
|
Makefile.in
|
|
- added installsh support for --ifdiff so the csug make file can use it
|
|
for the install target.
|
|
installsh,
|
|
csug/Makefile
|
|
- added instructions for building (cross-compiling) a boot file for
|
|
a supported machine type for which a boot file is not built by default.
|
|
BUILDING
|
|
- corrected CHEZSCHEMELIBS and CHEZSCHEMEEXTS index entries to be
|
|
CHEZSCHEMELIBDIRS and CHEZSCHEMELIBEXTS.
|
|
use.stex
|
|
- updated to curl stex version 1.2.1
|
|
configure
|
|
- updated the fix to S_mktime to work on windows. the struct tm
|
|
structure on windows does not have the tm_gmtoff field used in the
|
|
mac and linux version of the code.
|
|
stats.c
|
|
- updated the Windows makefiles for building and testing to remove links for
|
|
files that no longer exist, which was getting in the way of creating links
|
|
for files that do exist. Also updated the build batch file for Windows to
|
|
compile the nanopass framework separately before building the rest of the
|
|
scheme compiler and libraries.
|
|
s/Mf-{a6,i3,ta6,ti3}nt, s/bldnt.bat,
|
|
mats/Mf-{a6,i3,ta6,ti3}nt
|
|
- updated the read me to include a link to the Chez Scheme project page.
|
|
README.md
|
|
- fixed embarrassing typo in read me.
|
|
README.md
|
|
- profiler's html output refresh: mark the files as HTML5 rather
|
|
than HTML4; use target attributes rather than onclick events to
|
|
open links in specific windows; add a missing table row element;
|
|
replace the deprecated name attribute with an id attribute (and
|
|
replace the anchors with spans); and replace the deprecated valign
|
|
attribute with a style attribute.

|
|
newrelease, LOG
|
|
- replaced a couple of tabs
|
|
number.c
|
|
- updated the descriptions of statistics and related functions to
|
|
reflect the Version 9.3.1 change from sstats structures to sstats
|
|
records, with sstats times represented as time objects and sstats
|
|
bytes and counts represented as exact integers; also updated the
|
|
sstats-difference description to reflect that it no longer coerces
|
|
negative differences to zero. added a corresponding release note.
|
|
system.stex,
|

release_notes.stex
|
|
- added a cast to eliminate a warning

path-* procedures are passed a path that is not a string.
|

|
s/syntax.ss
|
|
- now forcing zlib configuration before compiling files that depend on
|
|
the zlib header files, since zlib's configure script can modify the
|
|
header files. removed ZlibInclude variable, which no longer serves
|
|
a purpose.
|
|
c/Mf-*, c/Makefile.*nt
|
|
- removed unnecessary datestamp.c target
|
|
c/Mf.*nt
|
|
- fixed unnessesary blocking in expeditor on Windows.
|
|
c/expeditor.c
|
|
- eliminated a couple of thread-safety issues and limitations on the
|
|
sizes of pathnames produced by expansion of tilde (home-directory)
|
|
prefixes by replacing S_pathname, S_pathname_impl, and S_homedir
|
|
with S_malloc_pathname, which always mallocs space for the result.
|
|
one thread-safety issue involved the use of static strings for expanded
|
|
pathnames and affected various file-system operations. the other
|
|
affected the file open routines and involved use of the incoming
|
|
pathname while deactivated. the incoming pathname is sometimes if not
|
|
always a pointer into a Scheme bytevector, which can be overwritten if a
|
|
collection occurs while the thread is deactivated. the size limitation
|
|
corresponded to the use of the static strings, which were limited to
|
|
PATH_MAX bytes. (PATH_MAX typically isn't actually the maximum path
|
|
length in contemporary operating systems.) eliminated similar issues
|
|
for wide pathnames under Windows by adding S_malloc_wide_pathname.
|
|
consumers of the old routines have been modified to use the new
|
|
routines and to free the result strings. the various file operations
|
|
now consistently treat a pathname with an unresolvable home directory
|
|
as a pathname that happens to start with a tilde. eliminated unused
|
|
foreign-symbol binding of "(cs)pathname" to S_pathname.
|
|
io.c, externs.h, new_io.c, prim5.c, scheme.c, prim.c
|
|
- various places where a call to close or gzclose was retried when
|
|
the close operation was interrupted no longer do so, since this can
|
|
cause problems when another thread has reallocated the same file
|
|
descriptor.
|
|
new_io.c
|
|
- now using vcvarsall type x86_amd64 rather than amd64 when the
|
|
former appears to supported and the latter does not, as is the
|
|
case with VS Express 2015.
|
|
c/Mf-a6nt, c/Mf-ta6nt
|
|
- commented out one of the thread mats that consistently causes
|
|
indefinite delays under Windows and OpenBSD due to starvation.
|
|
thread.ms
|
|
- increased wait time for a couple of subprocess responses
|
|
6.ms
|
|
- added call to collector to close files opened during iconv mats
|
|
specifically for when mats are run under Windows with no iconv dll.
|
|
io.ms
|
|
- fixed typo: VC/bin/vcvars64.bat => VC/bin/amd64/vcvars64.bat
|
|
c/Mf-a6nt, c/Mf-ta6nt
|
|
- scheme_mutex_t now uses volatile keyword for owner and count fields
|
|
because these fields can be accessed from multiple threads
|
|
concurrently. Updated $yield and $thread-check in mats/thread.ms to
|
|
be more tolerant of timing variability.
|
|
c/types.h, mats/thread.ms, release_notes.stex
|
|
- fixed three instances of unchecked mallocs reported by laqrix in
|
|
github issue #77.
|
|
io.c, schlib.c, thread.c
|
|
- continue the profiler's html output refresh: refine the styling
|
|

|
|
to reflect the refined look.

|
- add unicode support to the expression editor. entry and display now work
|
|
except that combining characters are not treated correctly for
|
|
line-wrapping. this addresses github issue #32 and part of issue #81.
|
|
c/expeditor.c, s/expeditor.ss
|
|
- moved s_ee_write_char function within the WIN32 check to allow the unicode
|
|
change to compile on windows. unicode is not yet supported in the windows
|
|
version of the repl.
|
|
c/expeditor.c
|
|
- reworked the S_create_thread_object to print an error and exit when
|
|
allocating the thread context fails from Sactivate_thread. before
|
|
this change, the error was raised on the main thread, which resulted
|
|
in strange behavior at best. also added who argument to
|
|
S_create_thread_object to allow it to report either Sactivate_thread
|
|
or fork-thread led to the error.
|
|
externs.h, schsig.c, scheme.c, thread.c
|
|
- fixed a bug in cpvalid resulting in it leaving behind a cpvalid-defer
|
|
form for later passes to choke on. also fixed cp0 to print the correct
|
|
name for cpvalid when it does this.
|
|
cpvalid.ss, cp0.ss,
|
|
misc.ms
|
|
- updated the prototype for s_ee_write_char to match the definition
|
|
expeditor.c

- fixed a side-effect preservation bug with non-trivial test-context
|
|
not-like patterns.
|

cp0.ms, 4.ms
|
|
- instead of default-exception handler, new-cafe establishes a handler

|
can be overridden, as we do in our own make files.
|
|
cafe.ss,

|
|
- fixed a bug in case and exclusive-cond syntax-error calls causing an
|
|
exception in syntax-error instead of the intended error message.
|
|
syntax.ss
|
|
- added tests for the case and exclusive-cond syntax-error calls
|
|
4.ms, root-experr-compile-0-f-f-f
|
|
- added print-extended-identifiers parameter. when #t, symbols like
|
|
1+ and +++ print without escapes.
|
|
priminfo.ss, print.ss,
|
|
6.ms
|
|
- added descriptions of print-extended-identifiers to the user's guide

|
|
of other log entries.
|
|
release_notes.stex,
|
|
intro.stex, io.stex
|
|
- updated the sockets example to work with the current version of Chez.
|
|
Change the foreign procedure definitions to use the more portable int
|
|
rather than integer-32. Switch to a custom port
|
|
[make-custom-binary-input/output-port] rather than a generic port
|
|
[make-input/output-port], which resulted in deleting quite a bit of
|
|
code. Fix various compiler warnings in the C code, and along the way,
|
|
fix a signedness bug in c_write that could have resulted in not writing
|
|
the full buffer (but reporting that it did) in the case of errors from
|
|
write.
|
|
examples/csocket.c, examples/socket.ss
|
|
- use high-precision clock time on Windows 8 and up
|
|
c/stats.c
|
|
- fixed profiling code that keyed profiling locations off of only the
|
|
bfp to instead key off of both the bfp and efp.
|
|
pdhtml.ss
|
|
- added Windows installer using the WiX Toolset
|
|
BUILDING, install/* (new)

- added procedure-arity-mask to report the allowed argument counts of
|
|
a compiled function. On a procedure from interpret or from one of
|
|
the trace procedures or syntactic forms, procedure-arity-mask
|
|
may report counts that are not actually allowed by the source
|
|
procedure.

floating-point register arguments as required for varargs functions
|

by the System V ABI.

x86_64.ss,

foreign.ms
|

foreign.ms
|
|
- added travis-ci automation script and a 'partialx' testing target to
|
|
allow us to perform more than a single run of testing without running
|
|
afoul of travis-ci's 50-minute build timeout. 'partialx' tests six
|
|
of the twelve configurations tested by 'allx'.
|
|
.travis.yml (new),
|
|
mats/Mf-base
|
|
- paired the 'partialx' down to just four test configurations, with one
|
|
interpreter run, to try to get the threaded builds into line with
|
|
travis-ci's timeout.
|
|
mats/Mf-base
|
|
- eliminated some direct assumptions that a vector's type/length field
|
|
is a fixnum and added meta-asserts to verify that it is in a couple of
|
|
others, to facilitate future changes to vector typing. vectors are
|
|
now treated essentially like fxvectors, strings, and bytevectors.
|
|
cmacros.ss, cpnanopass.ss, prims.ss, mkheader.ss,
|

alloc.c, gc.c, scheme.c
|
|
- fixed a few comments to refer to scheme.c rather than main.c
|
|
externs.h, globals.h, thread.c
|
|
- for 64-bit Windows systems, now copying foreign-procedure
|
|
double-precision floating-point register arguments to integer
|
|
registers as required for varargs functions. Windows does not
|
|
support single-precision floating-point arguments as varargs.
|

|
|
- various tweaks to the immutable object support; also taught cp0
|
|
to simplify ($fxu< (most-positive-fixnum) e) => (fx< e 0) so we
|
|
don't have any incentive in special casing length checks where
|
|
the maximum length happens to be (most-positive-fixnum).

fasl.c, gc.c, types.h
|
|
root-experr*, patch*
|
|
- generated bytevector=? procedure now gets out quickly on eq
|
|
arguments. cp0 optimizes away a number of additional equality
|
|
operations at optimize-level 3 (including bytevector=?) when
|
|
applied to the same variable references, as it already did for
|
|
eq?, eqv?, and equal?, at all optimize levels.

- fixed typo: fxvector-immutable-flag used in place of
|
|
bytevector-immutable-flag in computation of type-immutable-bytevector
|
|
cmacros.ss
|
|
- reallocated typed-object types, using previously unused tag #b010
|
|
for strings and giving bytevectors both #b001 and #b101 (the
|
|
latter for immutable bytevectors) so that the maximum bytevector
|
|
length on 32-bit machines is once again the most-positive fixnum.
|
|
treating bytevectors rather than strings or fxvectors (or even
|
|
vectors) special in this regard is appropriate since the maximum
|
|
number of bytes in a bytevector is maximum-length x 1 rather than
|
|
maximum-length x 4 for strings, fxvectors, and vectors on 32-bit
|
|
machines. with this change on 32-bit machines, a vector can
|
|
occupy up to 1/2 of virtual memory, strings and fxvectors 1/4,
|
|
and bytevectors 1/8.
|
|
cmacros.ss
|
|
- added record-type-equal-procedure, record-type-hash-procedure,
|
|
record-equal-procedure, and record-hash-procedure to enable
|
|
per-type customization of the behavior of equal? and equal-hash
|
|
for a record value
|
|
5_1.ss, newhash.ss, primdata.ss,
|
|
record.ms, root-experr*,
|
|
objects.stex
|
|
- adding dropped changes
|
|
record.ss,
|
|
root-experr*
|
|
- added entry for record-type-equal-procedure and friends
|
|
release_notes.stex
|
|
- changed copyright year to 2017
|
|
7.ss, scheme.1.in, comments of many files
|
|
- expanded the CSUG description of the handling of command-line
|
|
arguments not recognized as standard options and added a description
|
|
of the same to the COMMAND-LINE OPTIONS section of the man page.
|
|
did a bit of minor cleanup elsewhere in the man page.
|
|
use.stex, scheme.1.in
|
|
- destroy_thread now processes guardian entries
|
|
thread.c, 4.ms, release_notes.stex
|
|
- mutexes and conditions are now freed when no longer used via
|
|
$close-resurrected-mutexes&conditions, $keep-live primitive added
|
|
externs.h, prim5.c, thread.c, 4.ms, thread.ms, release_notes.stex,
|
|
7.ss, cpnanopass.ss, np-languages.ss, primdata.ss, prims.ss
|
|
- fix reduction for map and for-each with optimization level 3
|
|
to drop the expression, check that procedure has the correct
|
|
arity and is discardable or unsafe.
|
|
Also add a simplification for for-each with empty lists
|
|
with optimization level 2.
|
|
cp0.ss, 4.ms, primdata.ss
|
|
- fix invalid memory reference when enum-set-indexer procedure is not
|
|
passed a symbol
|
|
enum.ss, enum.ms, root-experr*, release_notes.stex
|
|
- fix overflow detection for fxsll, fxarithmetic-shift-left, and
|
|
fxarithmetic-shift
|
|
library.ss, fx.ms, release_notes.stex
|
|
- added ephemeron pairs and changed weak hashtables to use
|
|
ephemeron pairs for key--value mapping to avoid the key-in-value
|
|
problem
|
|
prims.ss, primdata.ss, newhash.ss, fasl.ss, mkheader.ss
|
|
cmacro.ss, prim5.c, fasl.c, gc.c, gcwrapper.c, types.h,
|
|
4.ms, hash.ms, objects.stex, smgmt.stex, csug.bib
|
|
- check_dirty_ephemeron now puts ephemerons whose keys haven't yet
|
|
been seen on the pending list rather than the trigger lists.
|
|
gc.c
|
|
- removed scan of space_ephemeron from check_heap because check_heap
|
|
as written can't handle the two link fields properly.
|
|
gcwrapper.c
|
|
- in the ephemerons mat that checks interaction between mutation and
|
|
collection, added generation arguments to the first two collect
|
|
calls so they always collect into the intended generation.
|
|
4.ms
|
|
- updated allx and bullyx patches
|
|
patch*
|
|
- fix strip-fasl-file for immutable strings and vectors,
|
|
fix an $oops call, and fix a vector-index increment in hashing
|
|
strip.ss, 7.ss, newhash.ss, misc.ms
|
|
- fix signature of fxbit-set?
|
|
primdata.ss
|
|
- more optimizations for map and for-each with explicit list
|
|
extend the reductions for map and for-each when the arguments are
|
|
explicit lists like (list 1 2 3 ...) or '(1 2 3 ...).
|
|
cp0.ss,
|
|
4.ms
|
|
- reverted to the preceding version of cp0 due to failure to preserve
|
|
the expected evaluation order in one of the mats; removed the
|
|
corresponding equivalent-expansion tests.
|
|
cp0.ss,
|
|
4.ms
|
|
- restored the map and for-each optimizations with a fix for the
|
|
evaluation-order bug.
