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.
original commit: 0a6a1e14e7ecb9e39fa7a10a8584ed2fec24cbf4
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
original commit: ad44924307c576eb2fc92e7958afe8b615a7f48b
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
original commit: d081c5b19a185597443f47101caa35b8c12084c7
- added a cast to eliminate warnings in c/number.c
- fixed bug in Windows version of directory-separator-predicate in s/6.ss when path-* procedures are passed a path that is not a string.
- fixed bug in s/cp0.ss on Windows with $foreign-wchar?.
- fixed spelling of non-existent

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.

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
original commit: 969fbf3b69f4ac9729847bae80dab92464b6d08c
structure on windows does not have the tm_gmtoff field used in the
mac and linux version of the code.
stats.c
original commit: 4339b856d85de4c949ef7c4e66ec679512809a58
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
original commit: df4194c83a9e67d1ec20165fc3e2def4ed8e8986
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
- rebuilt the boot files
original commit: 4bd78a692dd4ca2f88af5d404fd0993a2d141e7b
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@<a> and <m>@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 actually produces a number. added some related new tests,
including several found lacking by profiling. added a couple of
checks to number->string whose absence 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.

original commit: 03f2fe86171b0fd096238280b351ce365c701450
"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
original commit: 1d438978dfedef9a47839b3ee302196aa5d8eda1
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
original commit: b90a037c9fac18fdcbce73a42f28940e85a6c07b
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.
