19    Description:
20    
21    Changed the implementation of structure Unix so that the same stream
22    is returned every time one of the {text,bin}{In,Out}streamOf functions
23    is invoked on the same proc.  This is not what the spec currently
24    says -- although IMO it arguably should.  (See discussion below.)

37    Tag: blume-20040617-timer-unix
38    Description:
39    
40    Changed the interface of structures Timer and Unix to match the most
41    recent Basis spec.
42    
43    In the case of Unix there still seems to be an open/weird issue:
44    
45       The {text,bin}{In,Out}streamOf functions are supposed to create
46       fresh streams whenever they are called -- as opposed to have them
47       return the same stream every time.  This design is supposed to
48       prevent space leaks caused by proc values hanging on to streams.
49    
50       The reap function, on the other hand, is supposed to close the
51       streams.  This cannot be done without having a handle on the
52       stream in proc after all...
53    
54    I took the liberty to implement the following stopgap solution:
55    
56      The proc value hangs on to the most recently created stream(s).
57      Reap closes those.  If either or both of the two streams hadn't
58      been created at all yet, then reap will close the corresponding
59      file descriptors directly.
60    
61    PS: I don't understand the original space leak argument anymore.  If
62    a proc hangs on to the imperative stream, then I/O operations on those
63    will advance the state of the cached stream and avoid the space leak.

76    Tag: blume-20040525-group-owner
77    Description:
78    
79    CM now ignores (but still accepts) the "owner" information in group
80    descriptions.  The owner of a group is its next enclosing
81    library. Each group must have a unique owner.  (There is a virtual
82    "toplevel" library that owns groups which are not nested within a real
83    library.)  Previously, each group had to explicitly declare its owner,
84    and CM would check that such a declaration is correct.  The new scheme
85    is to have CM check that for each group there is precisely one owning
86    library.
87    
88    The advantage of the new scheme is that the programmer no longer needs
89    to maintain the somewhat annoying owner information.  The downside is
90    that CM cannot enforce the ownership rule across multiple runs of
91    CM.make.  Fortunately, enclosing the same group in two different
92    libraries A and B which are not part of the same program does not
93    cause real problems.

99    Description:
100    
101    Made the win32 version work again.  (Strangely, a misplaced comma had
102    slipped into win32-process.c which prevented the runtime from being
103    compiled correctly.)
104    
105    Also, included a minor addition to ml-build.bat analogous to what was
106    done in blume-20040519-ml-build.

111    Tag: blume-20040519-ml-build
112    Description:
113    
114    Arranged for ml-build to clean up after itself a little bit better.
115    The script generates a temporary SML source file and compiles it using
116    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
117    gets rid of those at the end, so they don't accumulate under .cm.
118    
119    This required a minor change to install.sh because the name of the
120    metadata directory (default: .cm) is actually configurable at
121    installation time.

135    Tag: blume-20040511-win32sock
136    Description:
137    
138    Added previously missing support for many socket-related functions
139    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
140    for the voluminous patch!
141    
142    (I have not tested this patch under win32 yet.)
143    
144    Here is David's e-mail:
145    
146    Hi,
147    
148    Attached to this email you find a diff against sml/nj 110.45
149    that will enable socket support under Windows.
150    
151    To apply the patch (using unix or cygwin)
152    1) gunzip runtime.diff.gz
153    2) "cd" into "src/runtime" in the source tree of a fresh
154       110.45 installation.
155    3) patch -p 1 < [your/path/to]runtime.diff
156    
157    The code compiles fine but has NOT yet been extensively tested.
158    I only ran a few tests for basic socket client functionality
159    (which worked fine).  Especially the functions that use ioctl
160    are not tested at all and might not work (see below).
161    
162    I implemented this since we want to move to a newer version of sml/nj
163    but need socket support in order to use it.  This is the first time I
164    even had a look at the sml/nj source,  so please review my changes
165    before making this part of the distribution!  Here are a few issues
166    that I think might be better for someone to solve who is more
167    familiar with the sml/nj source (and socket programming):
168    
169    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
170      exception since I could not figure out what the windows equivalent
171      of these functions is
172    
173    - In sockets-osdep.h there are a some #include statements that are
174      only used in a few files that include sockets-osdep.h
175    
176    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
177      does not process its return value since I don't know how to
178      report an error upwards.
179    
180    - It would probably be good to have a call to WSACleanup() when
181      the library is unloaded (if there is such a possibility).
182      Otherwise I think Windows will take care of this automatically
183      when the process finishes.
184    
185    - I used ioctlsocket() as a replacement for ioctl() but I have
186      no idea if that is actually the proper replacement on Windows.
187    
188    - All these issues are marked in the code by "FIXME" comments.
189    
190    We use sml/nj extensively in our products and are quite happy
191    with it.  I hope this contribution will help you.
192    
193    Keep up the good work!
194

227    Tag: blume-20040511-allsource
228    Description:
229    
230    The installer now honors the "src-smlnj" target again, although its meaning
231    has changed from "all sources required for the compiler" to "all sources
232    the installer knows about".  In other words, if you enable "src-smlnj"
233    in the "targets" file, then the installer will pull in sources for
234    everything.  (Notice that this refers to source code only.  Compiled
235    code is still only installed for modules that were requested explicitly
236    or which are required for other modules that were requested explicitly.)

269    Tag: leunga-20040319-cygwin-nlffi
270    Description:
271    
272    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
273    of SML/NJ.  The problem is that
274    
275       lib = dlopen(NULL, ...)
276       f   = dlsym(lib, "malloc");
277    
278    does not work on Windows unless we explicitly export symbols
279    such as 'malloc' during linking.  We fixed this by explicitly
280    exporting the required symbols with the magic gcc incantation:
281    
282        -Wl,--export-all cygwin.def
283    
284    where cygwin.def is a file containing all the symbols that
285    we wish to export.
286    
287    I suspect this is a Windows problem and we'll have to
288    do the same (somehow with windows compilers) when
289    we build the native win32 version with the system
290    calls LoadLibrary/GetProcAddress.

360    Eliminated the "dont_move_libraries" directive in config/targets.
361    (The mechanism was broken and could not be fixed easily.  Moreover,
362    there does not seem to be any reason not to move all libraries into
363    lib during installation.  I originally implemented this directive as a
364    backward-compatibility feature when I first introduced the new CM.
365    Now that things have been stable for a long time and going back to the
366    old CM is not an option, there is no reason to keep it around.)

415    Tag: blume-20030926-ppautoload
416    Description:
417    
418    I modified the read-eval-print loop so that the autoloader gets
419    invoked whenever the prettyprinter tries to look up a symbol that
420    is not currently defined in the toplevel environment but which
421    appears in CM's autoload registry.  As a result, we see far fewer of
422    those ?.Foo.Bar.xxx names in the prettyprinter's output.
423    
424    In addition to this I tried to clean up some pieces of the Basis
425    implementation (e.g., Socket, Word8Array) in order to prevent other
426    instances of these ?.Foo.Bar.xxx names from being printed.
427    
428    The mechanism that picks names for types still needs some work, though.
429    (Right now it seems that if there is a type A.t which is defined to
430    be B.u, but B is unavailable at toplevel, then A.t gets printed as
431    "?.B.u" although the perhaps more sensible solution would be to use
432    "A.t" in this case.  In other words, the prettyprinter should follow
433    a chain of DEFtycs not farther than there are corresponding toplevel
434    names in the current environment.)

439    Tag: blume-20030924-installer
440    Description:
441    
442    Another installer tweak:  All the ML code for the installer is now
443    compiled during CMB.make and put into a little library called
444    $smlnj/installer.cm.  The installation then simply invokes
445    
446       sml -m $smlnj/installer.cm
447    
448    and everything happens automagically.
449    
450    Win32:  ML code senses value of environment variable SMLNJ_HOME.
451    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
452            and BINDIR.
453    
454    The new scheme guarantees that the ML code responsible for the installation
455    is in sync with the APIs of the main system.  Also, the installer is
456    somewhat faster because the installer script is precompiled.

463    
464    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
465    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
466    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
467    implementations of non-blocking operations from CML's Socket
468    structure.

474    Description:
475    
476    1. Fixed SOCKET API and implementation to match Basis spec.
477       This required changing the internal representation of sockets to one
478       that remembers (for each socket file descriptor) whether it is currently
479       blocking or non-blocking.  This state is maintained lazily (i.e., a system
480       call is made only if the state actually needs to change).
481    
482    2. OS-specific details of sockets were moved into separate files, thus
483       making it possible to unify the bulk of the socket implementations
484       between Unix and Win32.
485    
486    3. CML's socket API changed accordingly.
487       (Note that we need to remove non-blocking functions from this API
488       since they are redundant in the case of CML!)
489    
490    4. CML's socket implementation now makes use of non-blocking functions
491       provided by Basis, thus removing all OS-dependent code from this part
492       of CML.
493    
494    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

537    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
538       this seems to be controversial at the moment) and used those in
539       Posix.ProcEnv.times.
540    
541    2. Added Time.{from,to}Nanoseconds to Time.
542    
543    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
544       For example, fromLargeInt never needs to look at more than 3 "big
545       digits" to get its 53 bits of precision.

607    Description:
608    
609    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
610    Modified config/install.bat to take advantage of it.  Also modified
611    config/install.sh (and called it config/new-install.sh) to take advantage
612    of it on Unix systems.  (The SML code is (supposed to be) platform-
613    independent.)
614    
615    The installer can now install everything under Win32
616    as well as under *nix as long as it compiles.
617    
618    Other changes:
619    
620      - made CML compile again under Win32
621      - made eXene compile under Win32 (by providing a fake structure UnixSock
622        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
623      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
624        same as type int;  under Win32 it isn't
625      - fixed some slice-related problems in the win32-specific parts of CML
626      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
627        (under Win32, the volume name is case-insensitive, and the
628        OS.Path code compares volume names for equality)

645    Description:
646    
647      1. Changed interface to vectors and arrays in Basis to match
648         (draft) Basis spec.
649      2. Added signatures and implementations of slices according to
650         Basis spec.
651      3. Edited source code throughout the system to make it compile again
652         under 1. and 2.  (In some cases code had to be added to have it
653         match the new signatures.)
654      4. MLRISC should be backward-compatible: the copies of the originals
655         of files that needed to change under 3. were retained, the .cm files
656         check the compiler version number and use old versions when
657         appropriate.
658      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
659         dirstream -> string option (in accordance with Basis spec).
660      6. When generating code that counts lines, ml-lex used function
661         CharVector.foldli, taking advantage of its old interface.
662         This has been replaced with the corresponding code from
663         CharVectorSlice.  (html-lex must be re-lexed!)
664      7. BitArray in smlnj-lib/Util has been extended/modified to match the
665         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
666      8. Removed temporary additions (fromInternal, toInternal) from the
667         (now obsolete) IntInf in smlnj-lib/Util.
668      9. Cleaned up structure Byte.
669     10. Added localOffset, scan, and fromString to Date (according to spec).
670         Cleaned/corrected implementation of Date.
671         (Still need to check for correctness; implement better canonicalizeDate.)
672     11. Added "scan" to signature IEEE_REAL.
673     12. Some improvements to IntInf [in particular: efficiency-hack for
674         mod and rem when second operand is 2 (for parity checks).]
675     13. Changed representation of type Time.time, using a single IntInf.int
676         value counting microseconds.  This considerably simplified the
677         implementation of structure Time.  We now support negative time
678         values; scan and fromString handle signs.
679     14. Functor PrimIO now takes two additional arguments (VectorSlice and
680         ArraySlice).

685    Tag: blume-20030828-intinf
686    Description:
687    
688    This is a major update which comes with a version number bump
689    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
690    and an implementation of IntInf in the Basis.
691    
692    There are a fairly large number of related changes and updates throughout
693    the system:
694    
695    Basis:
696            - Implemented IntInf.
697            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
698            - Added some missing Real64 operations, most notably Real.toLargeInt.
699            - Added FixedInt as a synonym for Int32.
700    
701    compiler:
702            * Added support for a built-in intinf type.
703              - literals
704              - pattern matching
705              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
706              - overloading on literals and operations
707    
708            This required adding a primitive type intinf, some additional
709            primops, and implementations for several non-trivial intinf
710            operations in Core.  (The intinf type is completely abstract
711            to the compiler; all operations get delegated back to the Core.)
712    
713            * Intinf equality is handled by polyequal.  However, the compiler
714            does not print its usual warning in this case (since polyequal
715            is the right thing to do there).
716    
717            * Improved the organization of structure InlineT.
718    
719            * A word about conversion primops:
720            If conversions involving intinf do not cancel out during
721            CPS contract, then the compiler must insert calls to Core functions.
722            Since all core access must be resolved already during the FLINT
723            translate phase, it would be too late a the time of CPS contract
724            to add new Core calls.  For this reason, conversion primops
725            for intinf carry two arguments:  1. the numeric argument that
726            they are supposed to convert, and 2. the Core function that
727            can help with this conversion if necessary.  If CPS contract
728            eliminates a primop, then the associated Core function becomes
729            dead and goes away.  Intinf conversion primops that do not get
730            eliminated by CPS contract get rewritten into calls of their
731            core functions by a separate, new phase.
732    
733    interactive system:
734            - Control.Print.intinfDepth controls max length of intinf constants
735            being printed. (Analogous to Control.Print.stringDepth.)
736            - Cleanup in printutil and pputil: got rid of unused stuff and
737            duplicates; replaced some of the code with code that makes better
738            use of library functionality.
739    
740    CM:
741            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
742            are no longer silent.
743    
744    CKIT:
745            Fixed mismatched uses of Int32 and LargeInt.  I always decided
746            in favor of LargeInt -- which is now the same as IntInf.
747            CKIT-knowledgable people should check whether this is what's
748            intended and otherwise change things back to using Int32 or
749            FixedInt.
750    
751    Throughout the code:
752            Started using IntInf.int literals and built-in operations
753            (e.g., comparison with 0) where this seems appropriate.

773    Description:
774    
775    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
776    
777        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
778    
779    This patch restores SML/NJ's ability to run under win32.  There are a
780    number of changes, including fixes for several bugs that had gone
781    unnoticed until now:
782    
783      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
784        trying to run the win32 version from within cygwin.)
785    
786      - There are a number of simple .bat scripts that substitute for their
787        corresponding Unix shell-scripts.  (See below.)
788    
789      - The internals of ml-build have been modified slightly.  The main
790        difference is that instead of calling ".link-sml" (or link-sml.bat)
791        using OS.Process.system, the ML process delegates this task back
792        to the script.  Otherwise problems arise in mixed environments such
793        as Cygwin where scripts look and work like Unix scripts, but
794        where OS.Process.system cannot run them.
795    
796      - In CM, the srcpath pickler used native pathname syntax -- which
797        is incorrect in the case of cross-compilation.  The new pickle format
798        is independent of platform-specific naming conventions.
799    
800      - Path configuration files (such as lib/pathconfig) can now choose
801        between native and standard syntax.  Placing a line of the form
802    
803            standard!
804    
805        into the file causes all subsequent paths to be interpreted using
806        CM standard pathname syntax (= Unix conventions); a line
807    
808            native!
809    
810        switches back to native style.  This was needed so that
811        path config files can be written portably, see src/system/pathconfig.
812    
813      - Runtime system:
814    
815          - win32-filesys.c:  get_file_time and set_file_time now
816            access modification time, not creation time.
817    
818          - I/O code made aware of new array representation.
819    
820          - Bug fixes in X86.prim.masm.
821    
822       - src/system/makeml made aware of win32. (For use under cygwin
823            and other Unix-environments for windows.)
824    
825       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
826         which caused BinIO.inputAll to fail consistently.
827    
828    .bat scripts:
829    
830       Windows .bat scripts assume that SMLNJ_HOME is defined.
831    
832       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
833         applications (sml, ml-yacc, ml-lex).
834       - ml-build.bat: analogous to ml-build.
835       - config\install.bat:  Analogous to config/install.sh.  This requires
836         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
837         (nmake etc. must be on the path, and vcvars32 must have been run.)
838         Moreover, sources for ml-lex and ml-yacc need to exist under src,
839         and the bootfile hierarchy must have been unpacked under
840         sml.boot.x86-win32.
841         The script is very primitive and does a poor job at error checking.
842         It only installs the base system, ml-lex, and ml-yacc.  No other
843         libraries are being installed (i.e., you get only those that
844         are part of the compiler.)
845       - link-sml.bat:  analogous to .link-sml, but not currently used
846    
847    Unrelated bug fixes:
848    
849      - ml-nlffigen now exports structures ST_* corresponding to incomplete
850        types.
851      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
852        otherwise.)

894       of the code is now more straightforward than before. (Treatment of
895       the above four constructs in translate.sml is much simpler than
896       the "macro-expansion" that was going on before.  Plus, the mach-
897       compiler no longer gets invoked just to be able to compile an
898       if-expression.)
899    
900    2. The ErrorMsg.Error exception is now caught and absorbed by the
901       interactive loop.

907    Description:
908    
909        Ported the runtime system to cygwin, which uses the unix
910    x86-unix bin files.  Missing/buggy features:
911    
912       o getnetbyname, getnetbyaddr: these functions seem to be missing in
913         the Cygwin library.
914       o Ctrl-C handling may be flaky.
915       o Windows system calls and Windows I/O are not supported.
916    
917       A new set of binfiles is located at:
918    
919         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
920    
921       This is only needed for bootstrapping the cygwin version of smlnj.
922       Other x86 versions can use the existing binfiles.

938    Description:
939    
940    Fixed a bug in Int.rem(x,y) where y is a power of 2 on x86.
941    The arguments to the SUBL instruction were swapped.

947    Description:
948    
949    Fixed a serious bug in the rewrite code for FP spilling/reloading that
950    sent the RA into an infinite loop when floating point registers get
951    spilled.  (Because of this bug, e.g., nucleic stopped compiling between
952    110.37 and 110.38.)
953    There was another set of potential problems related to the handling of
954    MLRISC annotations (but those did not yet cause real problems, apparently).

960    Description:
961    
962    Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
963    This fixes the problem of CM getting confused by files that suddenly
964    change their identity (e.g., by getting unlinked and recreated by some
965    text editor such as vi).  There might be a better/cheaper/cleaner way
966    of doing this, but for now this will have to do.
