19    Description:
20    
21    Minor cleanup in ML-Yacc rule printing mechanism.  This should fix a
22    problem with certain "as" patterns which previously got rendered
23    using incorrect syntax.

37    Tag: blume-20050114-heap2exec
38    Description:
39    
40    Implemented new (but still experimental) heap2exec facility.  This is
41    tested under Mac OS X and should work under Linux (will test shortly).
42    It will probably also work on the Sparc (will test some time later).
43    
44      - removed old "HACKED_STANDALONE" hack from runtime
45    
46    To be able to test this, uncomment the request for "heap2asm" in
47    config/targets prior to installation.  (Notice that this is different
48    from "heap2exec" mentioned below.  Not a typo.)
49    
50    To perform an actual test, run the command
51    
52       $ bin/heap2exec heapfile execfile
53    
54    (You can put heap2exec on your shell's path.)
55    
56    For example, run
57    
58      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
59    
60    This will create a standalone executable called "mly" which you can
61    then invoke directly as a command.

82    Tag: blume-20041221-longlong
83    Description:
84    
85    * Implemented access to signed and unsigned long long data in NLFFI.
86    (The parameter-passing part of the picture has not complete. But
87    data structure access seems to work.)
88    
89    * Fixed CM's incorrect assumption that the PPC is little-endian.
90      (On the Mac, it is big-endian.  And that's currently our only
91      PPC platform.)

97    Description:
98    
99    Some cleanup in the $c/memory.cm library: separated some concerns by
100    moving allocation code and memory access code each into their own
101    files.

107    Description:
108    
109        The Unix I/O library of SML/NJ on cygwin does not understand
110    Windows style pathname, so problems arise when SMLNJ_HOME is set
111    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
112    to a POSIX pathname on cygwin.

155    Date: 2004/12/14 17:30:00 CST
156    Tag: blume-20041214-spaces
157    Description:
158    
159    Hacked some of the scripts (in particular: the installer) to cope with
160    spaces in filenames a bit better.  But beware: the current "solution"
161    is likely still full of bugs and inherently incomplete.  (We need to
162    do away with those shell scripts for a comprehensive solution.)

175    Tag: blume-20041209-statistics
176    Description:
177    
178    Added two simple but potentially useful statistics modules to SML/NJ Library.
179    (See CHANGES file there.)

185    Description:
186    
187    smlnj-lib:
188    
189      Added function HashString.hashString' for substrings.
190      Hand-inlined CharVector.foldl into HashString (for speed).
191      Modified implementation of structure Atom to avoid extracting
192      strings from substrings unless necessary.
193      (Also see CHANGES file for smlnj-lib.)

198    Tag: blume-20041124-cml
199    Description:
200    
201    Made sure CML compiles when Position = Int64.
202

205    Date: 2004/11/24 14:30:00 CST
206    Tag: blume-20041124-position
207    Description:
208    
209    The compiler can now be compiled in a mode that makes structure Position
210    equal to Int64.  The default, however, is unchanged (Position = Int31)
211    for the time being.
212    
213    To enable 64-bit positions, use the following procedure:
214    
215    1. Start sml
216    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
217    3. Type
218          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
219    4. Run CMB.make() as usual.
220    
221    This is barely tested.  The only test so far was a little SML program
222    counting the number of characters in an 8-gigabyte file by
223    reading it character-by-character.  That test was successful.
224    
225    In support of 64-bit positions, a number of new functions have been
226    added to the runtime system.

232    Description:

234    Fixed a problem with unhelpful error messages related to problems with
235    .cm- or .sml files that appear as part of the sml command line.

266    Tag: blume-20041113-versiontool
267    Description:
268    
269    - Stripped down the versiontool: It now only handles the version number.
270      The date string is generated at bootstrap time (during makeml).
271    
272    - In a previous commit, fixed a minor issue with how polyequal is being
273      translated.  In particular, the code now "looks through" abstractions.
274      This results in slightly fewer polyEqual warnings and hopefully slightly
275      more efficient code.  Important examples for where this matters are
276      the new int64 and word64 types.

290    Tag: blume-20041111-more64
291    Description:
292    
293    All the pieces of Word64 are now there, with the exception of the
294    conversions from and to LargeWord. (Eventually these need to be identities,
295    but for the time being they don't even make sense because LargeWord is
296    32-bit wide.)
297    
298    Also started to add similar support for Int64, but major pieces of that
299    are still missing.
300

304    Tag: blume-20041111-word64
305    Description:
306    
307    Structure Word64 is now (almost) complete, word literals and patterns
308    seem to work.  There are a few odd pieces missing.  In particular,
309    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
310    at the moment.
311    
312    Making Word64 official would mean that LargeWord becomes Word64.  But
313    this requires extreme care because most word-word conversions have to
314    go through LargeWord, so making a mistake means loss of efficiency or
315    worse.  Eventually there will be a solution similar to (but actually
316    simpler than) what I did with IntInf.

343    
344                 =====================
345    
346    Also:
347    
348      - Changend config/srcarchiveurl from a file just
349        containing the URL string into a file containing
350        shell script code.  The code has access to the $VERSION variable.
351      - Made corresponding changes to config/install.sh and config/unpack.
352      - Default contents of config/srcarchiveurl uses $VERSION and
353        normally does not have to be edited to reflect a version change.
354    
355      (As a result, a version change can be done by just editing
356       config/version, the rest is now automatic.)

372    
373    This is the HISTORY entry for two earlier commits, both concerning
374    the x86 c-calls code in MLRISC:
375    
376      - added a missing LOAD in the code that deals with struct arguments
377      - made sure the caller does not add the wrong number of bytes to the
378        stack pointer after a call of a function returning a struct
379        (the callee already pops the implicit argument which points to
380         the space reserved for the result)

396    Tag: blume-20041020-standalone-backtrace
397    Description:
398    
399    Added a mechanism for getting back-trace information from standalone
400    programs.  Here is how it works:
401    
402       1. The part of the program from which you want to get backtrace
403          information (usually the whole program) should be wrapped with
404          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
405          main program could be modified from something like
406    
407             fun main (pgm, args) = ...
408    
409         to
410    
411            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
412    
413       2. To be able to access BackTrace.monitor, you have to add
414          library $smlnj-tdp/plugins.cm to the .cm file that contains your
415          main function.
416    
417       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
418          CM might have created in the past for your project).
419    
420       4. Build the system using this command line:
421    
422             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
423                      myprog.cm MyProg.main myprog
424    
425          instead of the usual
426    
427             ml-build myprog.cm MyProg.main myprog
428    
429    I changed a library name:
430    
431       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
432    
433    New libraries:
434    
435       $smlnj-tdp/back-trace.cm
436          -- when loaded causes the back-trace plugin to be installed
437       $smlnj-tdp/coverage.cm
438          -- when loaded causes the coverage plugin to be installed

453    Tag: blume-20041015-coverage
454    Description:
455    
456    * Test coverage tool added!
457    * Further reorganization of tracing-, debugging-, and profiling support:
458    
459        - moved original BTImp -- now called BackTrace -- into a separate
460          library called $/trace-debug-profile.cm
461        - eliminated all mentions of BTrace from SMLofNJ.Internals
462        - only the instrumentation mechanism is now left in the compiler proper
463        - BackTrace module is a plugin which is NOT plugged in by default
464        - Coverage module is another such plugin
465    
466    To get the benefits of any of these plugin modules, the code in
467    question must be compiled with tdp instrumentation turned on.  This
468    can be done by setting SMLofNJ.Internals.TDP.mode to true.
469    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
470    
471    Plugins are selected at link time.  (Pre-compiled instrumented code
472    can be re-loaded with different plugins in effect.)  When an
473    instrumented module is linked, whatever plugins are at that time
474    enabled will come into effect for that module.
475    
476    To enable the back-trace plugin, load library $/trace-debug-profile.cm
477    and invoke BackTrace.install() (e.g., from the interactive prompt).
478    To enable the coverage plugin, load the same library and invoke
479    Coverage.install().
480    
481    Back-traces are generated automatically on uncaught exceptions and
482    when the code in question explicitly invokes BackTrace.trigger().
483    
484    Coverage (and execution frequency-) information must be queried
485    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

502    Some rationalization of names:

507    This is is preparation of using the original back-trace

509    Trace/Debug/Profile.
510    
511    The control flag controlling whether instrumentation is on or off is now
512    registered under a different name, so instead of running sml as
513    
514     sml -Cinstrument.btrace-mode=true
515    
516    one has to say
517    
518     sml -Ctdp.instrument=true

534    Description:
535    
536    Fixed handling of keywords in .cm files: After seeing "is" the lexer
537    treats subsequent occurrences of "group", "library", "source", "is",
538    "*", and "-" as ordinary identifiers rather than keywords.
539    
540    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
541    is supposed to accept a tool argument called "source", but this did
542    not work because of the clash with the keyword.

585    Description:
586    
587    * Moved the "version" magic into its own little library under

589      a stable src/compiler/core.cm.
590    
591    * At the same time, structure CompilerVersion is now known as
592      structure SMLNJVersion.
593    
594    * Arranged for the version tool to NOT kick in when rebuilding the system
595      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
596      Also, loading the versiontool does not work when rebuilding the system
597      because CM is not properly initialized at that time.

602    Tag: blume-20040929-autoversion
603    Description:
604    
605    Implemented some CM magic to have
606        file src/compiler/TopLevel/main/version.sml
607    generated automagically.
608    The version is taken from two files: config/version and config/release.
609    The first is expected to contain a two-part version number such as 110.49.
610    The second should contain a single number, but it may be missing.
611    
612    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
613    time the version tool is loaded (which is the first time you say CMB.make),
614    then the tool will increment the value stored in config/release every
615    time CMB.make is invoked.
616    
617    The binfile format is now insensitive to anything beyond the first
618    two components of a version number, so bumping the release does not render
619    binfiles incompatible.  Auto-bumping can be used to keep track of versions
620    during development without invalidating existing binfiles.
621    
622    In any case, every CMB.make updates the date information in version.sml.
623    (This is the date that is printed in the banner.)

636    Tag: blume-20040927-controls
637    Description:
638    
639    Added two pieces of functionality to the Controls interface:
640    
641    1.   val save'restore: 'a control -> unit -> unit
642    
643       grabs the current value of the control in stage 1 and restores it
644       in stage 2.
645    
646    2.   val set' : 'a control * 'a -> unit -> unit
647    
648       stores the given value into the control in stage 2 (i.e., delayed)
649       but does all error checking in stage 1.
650       (This is for string controls that need to do parse their argument --
651        something that might fail.  In some cases, notably in CM, one
652        already knows the intended argument but wants to delay the actual
653        assignment until a time when error recovery would be more difficult.)
654    
655    Changed the handling of controls in tool arguments to classes "sml" and
656    "lazysml":
657       - use Controls.save'restore as a more robust way of restoring the
658         old value (in particular: without having to re-parse the string)
659       - use controls to handle the "overload" keyword in the init group
660         (I believe this change actually fixes a long-standing obscure bug.)

665    Tag: blume-20040927-lazysml
666    Description:
667    
668    Added a new tool class called "lazysml" to CM's tool chest.  The only
669    difference to "sml" is that compilation is done with Control.lazysml
670    set to true.  A source of class "lazysml" is automatically recognized
671    by a file name suffix of ".lml".
672    
673    In addition to the above feature, the original class "sml" now also
674    supports a tool argument "lazy" which has the same effect.  As a
675    result, the following three lines are equivalent:
676    
677        foo.sml : lazysml
678        foo.sml : sml (lazy)
679        foo.sml (lazy)
680    
681    The setting goes into effect both during parsing and during
682    compilation.  The original setting is restored right after parsing and
683    after compilation, respectively.
684    
685    In addition to all the above, there is also a general mechanism to set
686    ANY of the "controls" that are available at the command line via
687    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
688    apply as well. (In fact, "lazy" is implemented as a special case of
689    the general mechanism.)
690    
691    The .cm file syntax uses a new keyword tool argument called "with".
692    There are several ways of indicating the desired settings:
693    
694        foo.sml (with:parser.quotations=true)
695        foo.sml (with:(name:parser.quotations value:true))
696        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
697        foo.sml (with:(name1=value1 name2=value2 ...))
698        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
699    
700        etc.
701    
702    Another possible abbreviation is to leave out the =v or value:v part
703    if the name refers to a boolean control (in which case the value is
704    taken to be true).  Thus, one could get lazy sml also by saying:
705    
706        foo.sml (with:parser.lazy-keyword=true)
707        foo.sml (with:parser.lazy-keyword)
708        foo.sml (with:(name:parser.lazy-keyword value:true))
709        foo.sml (with:(name:parser.lazy-keyword))

926    
927    Added NLFFI support for Win32, adapted from a patch provided by David
928    Hansel.  This is currently completely untested.  Also, the issue
929    concerning stdcall vs. ccall is still unresolved.

936    
937    Gearing up towards 110.47...
938    
939    - various minor bugfixes to ml-nlffigen
940    - a beginning of a manual for nlffi
941    
942    - eliminated 'export name=value' in config/install.sh as this does
943      not work with certain versions of /bin/sh
944      (Thanks to David King at Motorola for catching this.)
945    
946    - several bugfixes provided or suggested by David Hansel at Reactive Systems:
947      - added a test for tm==NULL to gmtime.c and localtime.c
948      - applied patch for incorrect GetFileTime under win32
949      - toSeconds -> toMilliseconds in Win32/win32-process.sml

956    
957    - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
958      for a typedef to an incomplete type, but leave out the "typ" member.
959      (This is just for consistency.)
960    - Started to produce what is supposed to become better (i.e., comprehensive)
961      documentation of what ml-nlffigen does and produces.

967    Description:
968    
969    Added C_UNION to c-calls/c-types.sml and updated the machinery
970    (ml-nlffigen, cproto.sml) that conveys C function interface
971    information to the code generator.
972    
973    However, the actual architecture-specific implementation of function
974    arguments and results that are C unions is still not implemented.

1006    Description:
1007    
1008    - use paramAlloc to report c-calls with too many arguments
1009      (for PPC version where parameter area is pre-allocated)
1010    - added ccall_maxargspace to machspec (to implement the above)
1011    - made "make" commend in CM's "make" tool configurable
1012    - added option (default: on) for passing the name of the SML/NJ's "bin"
1013      directory to "make"; the call looks like this:
1014    
1015         make <options> SMLNJ_BINDIR=<dir> <target>
1016    
1017      This can be used by the Makefile to, e.g., pick the "right" version
1018      of ml-nlffigen.
1019    - minor code tweaks

1026    
1027    NLFFI under Mac OS X now working (sort of).  This is largely untested,
1028    though.
1029    
1030    Note:  1. You have to make a new, clean build of the runtime system.
1031           2. There are new BOOTFILES, you have to use them!
1032              (Doing the bootstrap process yourself would be *very* painful!
1033               If you absolutely have to do it, build the system under
1034               a different architecture and then cross-compile.)
1035    
1036    Version bumped to 110.46.1 to account for runtime data format changes.

1043    
1044    Changed the implementation of structure Unix so that the same stream
1045    is returned every time one of the {text,bin}{In,Out}streamOf functions
1046    is invoked on the same proc.  This is not what the spec currently
1047    says -- although IMO it arguably should.  (See discussion below.)

1061    Description:
1062    
1063    Changed the interface of structures Timer and Unix to match the most
1064    recent Basis spec.
1065    
1066    In the case of Unix there still seems to be an open/weird issue:
1067    
1068       The {text,bin}{In,Out}streamOf functions are supposed to create
1069       fresh streams whenever they are called -- as opposed to have them
1070       return the same stream every time.  This design is supposed to
1071       prevent space leaks caused by proc values hanging on to streams.
1072    
1073       The reap function, on the other hand, is supposed to close the
1074       streams.  This cannot be done without having a handle on the
1075       stream in proc after all...
1076    
1077    I took the liberty to implement the following stopgap solution:
1078    
1079      The proc value hangs on to the most recently created stream(s).
1080      Reap closes those.  If either or both of the two streams hadn't
1081      been created at all yet, then reap will close the corresponding
1082      file descriptors directly.
1083    
1084    PS: I don't understand the original space leak argument anymore.  If
1085    a proc hangs on to the imperative stream, then I/O operations on those
1086    will advance the state of the cached stream and avoid the space leak.

1100    Description:
1101    
1102    CM now ignores (but still accepts) the "owner" information in group
1103    descriptions.  The owner of a group is its next enclosing
1104    library. Each group must have a unique owner.  (There is a virtual
1105    "toplevel" library that owns groups which are not nested within a real
1106    library.)  Previously, each group had to explicitly declare its owner,
1107    and CM would check that such a declaration is correct.  The new scheme
1108    is to have CM check that for each group there is precisely one owning
1109    library.
1110    
1111    The advantage of the new scheme is that the programmer no longer needs
1112    to maintain the somewhat annoying owner information.  The downside is
1113    that CM cannot enforce the ownership rule across multiple runs of
1114    CM.make.  Fortunately, enclosing the same group in two different
1115    libraries A and B which are not part of the same program does not
1116    cause real problems.

1124    Made the win32 version work again.  (Strangely, a misplaced comma had
1125    slipped into win32-process.c which prevented the runtime from being
1126    compiled correctly.)
1127    
1128    Also, included a minor addition to ml-build.bat analogous to what was
1129    done in blume-20040519-ml-build.

1135    Description:
1136    
1137    Arranged for ml-build to clean up after itself a little bit better.
1138    The script generates a temporary SML source file and compiles it using
1139    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
1140    gets rid of those at the end, so they don't accumulate under .cm.
1141    
1142    This required a minor change to install.sh because the name of the
1143    metadata directory (default: .cm) is actually configurable at
1144    installation time.

1165  (I have not tested this patch under win32 yet.)  (I have not tested this patch under win32 yet.)
1166    
1167    Here is David's e-mail:
1168    
1169    Hi,
1170    
1171    Attached to this email you find a diff against sml/nj 110.45
1172    that will enable socket support under Windows.
1173    
1174    To apply the patch (using unix or cygwin)
1175    1) gunzip runtime.diff.gz
1176    2) "cd" into "src/runtime" in the source tree of a fresh
1177       110.45 installation.
1178    3) patch -p 1 < [your/path/to]runtime.diff
1179    
1180    The code compiles fine but has NOT yet been extensively tested.
1181    I only ran a few tests for basic socket client functionality
1182    (which worked fine).  Especially the functions that use ioctl
1183    are not tested at all and might not work (see below).
1184    
1185    I implemented this since we want to move to a newer version of sml/nj
1186    but need socket support in order to use it.  This is the first time I
1187    even had a look at the sml/nj source,  so please review my changes
1188    before making this part of the distribution!  Here are a few issues
1189    that I think might be better for someone to solve who is more
1190    familiar with the sml/nj source (and socket programming):
1191    
1192    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1193      exception since I could not figure out what the windows equivalent
1194      of these functions is
1195    
1196    - In sockets-osdep.h there are a some #include statements that are
1197      only used in a few files that include sockets-osdep.h
1198    
1199    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1200      does not process its return value since I don't know how to
1201      report an error upwards.
1202    
1203    - It would probably be good to have a call to WSACleanup() when
1204      the library is unloaded (if there is such a possibility).
1205      Otherwise I think Windows will take care of this automatically
1206      when the process finishes.
1207    
1208    - I used ioctlsocket() as a replacement for ioctl() but I have
1209      no idea if that is actually the proper replacement on Windows.
1210    
1211    - All these issues are marked in the code by "FIXME" comments.
1212    
1213    We use sml/nj extensively in our products and are quite happy
1214    with it.  I hope this contribution will help you.
1215    
1216    Keep up the good work!
1217    
1218    David
