27    Description:
28    
29    Fixed serious bug (brown paper bag variety) in new implementation of
30    structure Atom in CML.  (I had accidentally used a mailbox instead of
31    an mvar, leaving the door open for races.)

45    Description:
46    
47    Brought back SMLofNJ.Susp.  The underlying suspension type is the one
48    implemented in Core -- which means that it is the same as the one used
49    by the lazy extension.

72    Tag: blume-20050210-longlong
73    Description:
74    
75    Implemented "long long" arguments and results for NLFFI.  (Only the
76    PPC/MacOS implementation is complete, the other backends still need to
77    be updated.)

82    Tag: blume-20050124-mlyacc
83    Description:
84    
85    Minor cleanup in ML-Yacc rule printing mechanism.  This should fix a
86    problem with certain "as" patterns which previously got rendered
87    using incorrect syntax.

93    Description:
94    
95    Made time profiling code (interrupt handler) in runtime system aware
96    of new array representation.

101    Tag: blume-20050114-heap2exec
102    Description:
103    
104    Implemented new (but still experimental) heap2exec facility.  This is
105    tested under Mac OS X and should work under Linux (will test shortly).
106    It will probably also work on the Sparc (will test some time later).
107    
108      - removed old "HACKED_STANDALONE" hack from runtime
109    
110    To be able to test this, uncomment the request for "heap2asm" in
111    config/targets prior to installation.  (Notice that this is different
112    from "heap2exec" mentioned below.  Not a typo.)
113    
114    To perform an actual test, run the command
115    
116       $ bin/heap2exec heapfile execfile
117    
118    (You can put heap2exec on your shell's path.)
119    
120    For example, run
121    
122      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
123    
124    This will create a standalone executable called "mly" which you can
125    then invoke directly as a command.

138    Tag: blume-20041223-santa
139    Description:
140    
141    Made ml-build script "smarter" (but only very little).
142

145    Date: 2004/12/21 15:05:00 CST
146    Tag: blume-20041221-longlong
147    Description:
148    
149    * Implemented access to signed and unsigned long long data in NLFFI.
150    (The parameter-passing part of the picture has not complete. But
151    data structure access seems to work.)
152    
153    * Fixed CM's incorrect assumption that the PPC is little-endian.
154      (On the Mac, it is big-endian.  And that's currently our only
155      PPC platform.)
156

160    Tag: blume-20041221-memory
161    Description:
162    
163    Some cleanup in the $c/memory.cm library: separated some concerns by
164    moving allocation code and memory access code each into their own
165    files.

170    Tag: leunga-20041217-cygwin-smlnj-home
171    Description:
172    
173        The Unix I/O library of SML/NJ on cygwin does not understand
174    Windows style pathname, so problems arise when SMLNJ_HOME is set
175    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
176    to a POSIX pathname on cygwin.

194    Description:
195    
196    - HashString.hashString' -> HashString.hashSubstring
197    - corresponding changes in atom.sml
198    - "de-compressed" (aka. un-obfuscated) code for UnivariateStats and
199      added some comments

219    Date: 2004/12/14 17:30:00 CST
220    Tag: blume-20041214-spaces
221    Description:
222    
223    Hacked some of the scripts (in particular: the installer) to cope with
224    spaces in filenames a bit better.  But beware: the current "solution"
225    is likely still full of bugs and inherently incomplete.  (We need to
226    do away with those shell scripts for a comprehensive solution.)

239    Tag: blume-20041209-statistics
240    Description:
241    
242    Added two simple but potentially useful statistics modules to SML/NJ Library.
243    (See CHANGES file there.)

248    Tag: blume-20041201-atom
249    Description:
250    
251    smlnj-lib:
252    
253      Added function HashString.hashString' for substrings.
254      Hand-inlined CharVector.foldl into HashString (for speed).
255      Modified implementation of structure Atom to avoid extracting
256      strings from substrings unless necessary.
257      (Also see CHANGES file for smlnj-lib.)

262    Tag: blume-20041124-cml
263    Description:
264    
265    Made sure CML compiles when Position = Int64.
266    
267    ----------------------------------------------------------------------
268    Name: Matthias Blume (blume (at) tti - c (dot) org)
269    Date: 2004/11/24 14:30:00 CST
270    Tag: blume-20041124-position
271    Description:
272    
273    The compiler can now be compiled in a mode that makes structure Position
274    equal to Int64.  The default, however, is unchanged (Position = Int31)
275    for the time being.
276    
277    To enable 64-bit positions, use the following procedure:
278    
279    1. Start sml
280    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
281    3. Type
282          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
283    4. Run CMB.make() as usual.
284    
285    This is barely tested.  The only test so far was a little SML program
286    counting the number of characters in an 8-gigabyte file by
287    reading it character-by-character.  That test was successful.
288    
289    In support of 64-bit positions, a number of new functions have been
290    added to the runtime system.

295    Tag: blume-20041123-useFile
296    Description:
297    
298    Fixed a problem with unhelpful error messages related to problems with
299    .cm- or .sml files that appear as part of the sml command line.

330    Tag: blume-20041113-versiontool
331    Description:
332    
333    - Stripped down the versiontool: It now only handles the version number.
334      The date string is generated at bootstrap time (during makeml).
335    
336    - In a previous commit, fixed a minor issue with how polyequal is being
337      translated.  In particular, the code now "looks through" abstractions.
338      This results in slightly fewer polyEqual warnings and hopefully slightly
339      more efficient code.  Important examples for where this matters are
340      the new int64 and word64 types.

354    Tag: blume-20041111-more64
355    Description:
356    
357    All the pieces of Word64 are now there, with the exception of the
358    conversions from and to LargeWord. (Eventually these need to be identities,
359    but for the time being they don't even make sense because LargeWord is
360    32-bit wide.)
361    
362    Also started to add similar support for Int64, but major pieces of that
363    are still missing.
364    
365    ----------------------------------------------------------------------

368    Tag: blume-20041111-word64
369    Description:
370    
371    Structure Word64 is now (almost) complete, word literals and patterns
372    seem to work.  There are a few odd pieces missing.  In particular,
373    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
374    at the moment.
375    
376    Making Word64 official would mean that LargeWord becomes Word64.  But
377    this requires extreme care because most word-word conversions have to
378    go through LargeWord, so making a mistake means loss of efficiency or
379    worse.  Eventually there will be a solution similar to (but actually
380    simpler than) what I did with IntInf.

388    More 64-bit hacking (but still not even half-way there yet).
389    Also, some assorted improvements to the handling of 8-bit words.

407    
408                 =====================
409    
410    Also:
411    
412      - Changend config/srcarchiveurl from a file just
413        containing the URL string into a file containing
414        shell script code.  The code has access to the $VERSION variable.
415      - Made corresponding changes to config/install.sh and config/unpack.
416      - Default contents of config/srcarchiveurl uses $VERSION and
417        normally does not have to be edited to reflect a version change.
418    
419      (As a result, a version change can be done by just editing
420       config/version, the rest is now automatic.)

435    Description:
436    
437    This is the HISTORY entry for two earlier commits, both concerning
438    the x86 c-calls code in MLRISC:
439    
440      - added a missing LOAD in the code that deals with struct arguments
441      - made sure the caller does not add the wrong number of bytes to the
442        stack pointer after a call of a function returning a struct
443        (the callee already pops the implicit argument which points to
444         the space reserved for the result)

460    Tag: blume-20041020-standalone-backtrace
461    Description:
462    
463    Added a mechanism for getting back-trace information from standalone
464    programs.  Here is how it works:
465    
466       1. The part of the program from which you want to get backtrace
467          information (usually the whole program) should be wrapped with
468          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
469          main program could be modified from something like
470    
471             fun main (pgm, args) = ...
472    
473         to
474    
475            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
476    
477       2. To be able to access BackTrace.monitor, you have to add
478          library $smlnj-tdp/plugins.cm to the .cm file that contains your
479          main function.
480    
481       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
482          CM might have created in the past for your project).
483    
484       4. Build the system using this command line:
485    
486             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
487                      myprog.cm MyProg.main myprog
488    
489          instead of the usual
490    
491             ml-build myprog.cm MyProg.main myprog
492    
493    I changed a library name:
494    
495       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
496    
497    New libraries:
498    
499       $smlnj-tdp/back-trace.cm
500          -- when loaded causes the back-trace plugin to be installed
501       $smlnj-tdp/coverage.cm
502          -- when loaded causes the coverage plugin to be installed

518    Description:
519    
520    * Test coverage tool added!
521    * Further reorganization of tracing-, debugging-, and profiling support:
522    
523        - moved original BTImp -- now called BackTrace -- into a separate
524          library called $/trace-debug-profile.cm
525        - eliminated all mentions of BTrace from SMLofNJ.Internals
526        - only the instrumentation mechanism is now left in the compiler proper
527        - BackTrace module is a plugin which is NOT plugged in by default
528        - Coverage module is another such plugin
529    
530    To get the benefits of any of these plugin modules, the code in
531    question must be compiled with tdp instrumentation turned on.  This
532    can be done by setting SMLofNJ.Internals.TDP.mode to true.
533    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
534    
535    Plugins are selected at link time.  (Pre-compiled instrumented code
536    can be re-loaded with different plugins in effect.)  When an
537    instrumented module is linked, whatever plugins are at that time
538    enabled will come into effect for that module.
539    
540    To enable the back-trace plugin, load library $/trace-debug-profile.cm
541    and invoke BackTrace.install() (e.g., from the interactive prompt).
542    To enable the coverage plugin, load the same library and invoke
543    Coverage.install().
544    
545    Back-traces are generated automatically on uncaught exceptions and
546    when the code in question explicitly invokes BackTrace.trigger().
547    
548    Coverage (and execution frequency-) information must be queried
549    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

566    Some rationalization of names:

570    
571    This is is preparation of using the original back-trace
572    instrumentation for other purposes.  "TDP" stands for
573    Trace/Debug/Profile.
574    
575    The control flag controlling whether instrumentation is on or off is now
576    registered under a different name, so instead of running sml as
577    
578     sml -Cinstrument.btrace-mode=true
579    
580    one has to say
581    
582     sml -Ctdp.instrument=true

598    Description:

600    Fixed handling of keywords in .cm files: After seeing "is" the lexer
601    treats subsequent occurrences of "group", "library", "source", "is",
602    "*", and "-" as ordinary identifiers rather than keywords.
603    
604    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
605    is supposed to accept a tool argument called "source", but this did
606    not work because of the clash with the keyword.

649    Description:
650    
651    * Moved the "version" magic into its own little library under

653      a stable src/compiler/core.cm.
654    
655    * At the same time, structure CompilerVersion is now known as
656      structure SMLNJVersion.
657    
658    * Arranged for the version tool to NOT kick in when rebuilding the system
659      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
660      Also, loading the versiontool does not work when rebuilding the system
661      because CM is not properly initialized at that time.

666    Tag: blume-20040929-autoversion
667    Description:
668    
669    Implemented some CM magic to have
670        file src/compiler/TopLevel/main/version.sml
671    generated automagically.
672    The version is taken from two files: config/version and config/release.
673    The first is expected to contain a two-part version number such as 110.49.
674    The second should contain a single number, but it may be missing.
675    
676    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
677    time the version tool is loaded (which is the first time you say CMB.make),
678    then the tool will increment the value stored in config/release every
679    time CMB.make is invoked.
680    
681    The binfile format is now insensitive to anything beyond the first
682    two components of a version number, so bumping the release does not render
683    binfiles incompatible.  Auto-bumping can be used to keep track of versions
684    during development without invalidating existing binfiles.
685    
686    In any case, every CMB.make updates the date information in version.sml.
687    (This is the date that is printed in the banner.)

700    Tag: blume-20040927-controls
701    Description:
702    
703    Added two pieces of functionality to the Controls interface:
704    
705    1.   val save'restore: 'a control -> unit -> unit
706    
707       grabs the current value of the control in stage 1 and restores it
708       in stage 2.
709    
710    2.   val set' : 'a control * 'a -> unit -> unit
711    
712       stores the given value into the control in stage 2 (i.e., delayed)
713       but does all error checking in stage 1.
714       (This is for string controls that need to do parse their argument --
715        something that might fail.  In some cases, notably in CM, one
716        already knows the intended argument but wants to delay the actual
717        assignment until a time when error recovery would be more difficult.)
718    
719    Changed the handling of controls in tool arguments to classes "sml" and
720    "lazysml":
721       - use Controls.save'restore as a more robust way of restoring the
722         old value (in particular: without having to re-parse the string)
723       - use controls to handle the "overload" keyword in the init group
724         (I believe this change actually fixes a long-standing obscure bug.)

729    Tag: blume-20040927-lazysml
730    Description:
731    
732    Added a new tool class called "lazysml" to CM's tool chest.  The only
733    difference to "sml" is that compilation is done with Control.lazysml
734    set to true.  A source of class "lazysml" is automatically recognized
735    by a file name suffix of ".lml".
736    
737    In addition to the above feature, the original class "sml" now also
738    supports a tool argument "lazy" which has the same effect.  As a
739    result, the following three lines are equivalent:
740    
741        foo.sml : lazysml
742        foo.sml : sml (lazy)
743        foo.sml (lazy)
744    
745    The setting goes into effect both during parsing and during
746    compilation.  The original setting is restored right after parsing and
747    after compilation, respectively.
748    
749    In addition to all the above, there is also a general mechanism to set
750    ANY of the "controls" that are available at the command line via
751    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
752    apply as well. (In fact, "lazy" is implemented as a special case of
753    the general mechanism.)
754    
755    The .cm file syntax uses a new keyword tool argument called "with".
756    There are several ways of indicating the desired settings:
757    
758        foo.sml (with:parser.quotations=true)
759        foo.sml (with:(name:parser.quotations value:true))
760        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
761        foo.sml (with:(name1=value1 name2=value2 ...))
762        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
763    
764        etc.
765    
766    Another possible abbreviation is to leave out the =v or value:v part
767    if the name refers to a boolean control (in which case the value is
768    taken to be true).  Thus, one could get lazy sml also by saying:
769    
770        foo.sml (with:parser.lazy-keyword=true)
771        foo.sml (with:parser.lazy-keyword)
772        foo.sml (with:(name:parser.lazy-keyword value:true))
773        foo.sml (with:(name:parser.lazy-keyword))

924    single_source_shortest_paths in dijkstra.sml was observed to get wrong
925    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
926    
927    The problem is that following the expression A.update(dist,s,Num.zero)
928    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

1125    Description:
1126    
1127    Changed the interface of structures Timer and Unix to match the most
1128    recent Basis spec.
1129    
1130    In the case of Unix there still seems to be an open/weird issue:
1131    
1132       The {text,bin}{In,Out}streamOf functions are supposed to create
1133       fresh streams whenever they are called -- as opposed to have them
1134       return the same stream every time.  This design is supposed to
1135       prevent space leaks caused by proc values hanging on to streams.
1136    
1137       The reap function, on the other hand, is supposed to close the
1138       streams.  This cannot be done without having a handle on the
1139       stream in proc after all...
1140    
1141    I took the liberty to implement the following stopgap solution:
1142    
1143      The proc value hangs on to the most recently created stream(s).
1144      Reap closes those.  If either or both of the two streams hadn't
1145      been created at all yet, then reap will close the corresponding
1146      file descriptors directly.
1147    
1148    PS: I don't understand the original space leak argument anymore.  If
1149    a proc hangs on to the imperative stream, then I/O operations on those
1150    will advance the state of the cached stream and avoid the space leak.

1164    Description:
1165    
1166    CM now ignores (but still accepts) the "owner" information in group
1167    descriptions.  The owner of a group is its next enclosing
1168    library. Each group must have a unique owner.  (There is a virtual
1169    "toplevel" library that owns groups which are not nested within a real
1170    library.)  Previously, each group had to explicitly declare its owner,
1171    and CM would check that such a declaration is correct.  The new scheme
1172    is to have CM check that for each group there is precisely one owning
1173    library.
1174    
1175    The advantage of the new scheme is that the programmer no longer needs
1176    to maintain the somewhat annoying owner information.  The downside is
1177    that CM cannot enforce the ownership rule across multiple runs of
1178    CM.make.  Fortunately, enclosing the same group in two different
1179    libraries A and B which are not part of the same program does not
1180    cause real problems.

1199    Description:
1200    
1201    Arranged for ml-build to clean up after itself a little bit better.
1202    The script generates a temporary SML source file and compiles it using
1203    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
1204    gets rid of those at the end, so they don't accumulate under .cm.
1205    
1206    This required a minor change to install.sh because the name of the
1207    metadata directory (default: .cm) is actually configurable at
1208    installation time.

1224    
1225    Added previously missing support for many socket-related functions
1226    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
1227    for the voluminous patch!
1228    
1229    (I have not tested this patch under win32 yet.)
1230    
1231    Here is David's e-mail:
1232    
1233    Hi,
1234    
1235    Attached to this email you find a diff against sml/nj 110.45
1236    that will enable socket support under Windows.
1237    
1238    To apply the patch (using unix or cygwin)
1239    1) gunzip runtime.diff.gz
1240    2) "cd" into "src/runtime" in the source tree of a fresh
1241       110.45 installation.
1242    3) patch -p 1 < [your/path/to]runtime.diff
1243    
1244    The code compiles fine but has NOT yet been extensively tested.
1245    I only ran a few tests for basic socket client functionality
1246    (which worked fine).  Especially the functions that use ioctl
1247    are not tested at all and might not work (see below).
1248    
1249    I implemented this since we want to move to a newer version of sml/nj
1250    but need socket support in order to use it.  This is the first time I
1251    even had a look at the sml/nj source,  so please review my changes
1252    before making this part of the distribution!  Here are a few issues
1253    that I think might be better for someone to solve who is more
1254    familiar with the sml/nj source (and socket programming):
1255    
1256    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1257      exception since I could not figure out what the windows equivalent
1258      of these functions is
1259    
1260    - In sockets-osdep.h there are a some #include statements that are
1261      only used in a few files that include sockets-osdep.h
1262    
1263    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1264      does not process its return value since I don't know how to
1265      report an error upwards.
1266    
1267    - It would probably be good to have a call to WSACleanup() when
1268      the library is unloaded (if there is such a possibility).
1269      Otherwise I think Windows will take care of this automatically
1270      when the process finishes.
1271    
1272    - I used ioctlsocket() as a replacement for ioctl() but I have
1273      no idea if that is actually the proper replacement on Windows.
1274    
1275    - All these issues are marked in the code by "FIXME" comments.
1276    
1277    We use sml/nj extensively in our products and are quite happy
1278    with it.  I hope this contribution will help you.
1279    
1280    Keep up the good work!
1281

1321    everything.  (Notice that this refers to source code only.  Compiled
1322    code is still only installed for modules that were requested explicitly
1323    or which are required for other modules that were requested explicitly.)

1357    Description:
1358    
1359    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
1360    of SML/NJ.  The problem is that
1361    
1362       lib = dlopen(NULL, ...)
1363       f   = dlsym(lib, "malloc");
1364    
1365    does not work on Windows unless we explicitly export symbols
1366    such as 'malloc' during linking.  We fixed this by explicitly
1367    exporting the required symbols with the magic gcc incantation:
1368    
1369        -Wl,--export-all cygwin.def
1370    
1371    where cygwin.def is a file containing all the symbols that
1372    we wish to export.
1373    
1374    I suspect this is a Windows problem and we'll have to
1375    do the same (somehow with windows compilers) when
1376    we build the native win32 version with the system
1377    calls LoadLibrary/GetProcAddress.

1392    Description:
1393    
1394    Fixed problem with installer script (unix only) where bin/ml-yacc and
1395    friends pointed (via symlinks) to absolute locations instead of just
1396    .run-sml.  This was reported by Vesa A Norrman.

1445    Description:
1446    
1447    Eliminated the "dont_move_libraries" directive in config/targets.
1448    (The mechanism was broken and could not be fixed easily.  Moreover,
1449    there does not seem to be any reason not to move all libraries into
1450    lib during installation.  I originally implemented this directive as a
1451    backward-compatibility feature when I first introduced the new CM.
1452    Now that things have been stable for a long time and going back to the
1453    old CM is not an option, there is no reason to keep it around.)

1502    Tag: blume-20030926-ppautoload
1503    Description:
1504    
1505    I modified the read-eval-print loop so that the autoloader gets
1506    invoked whenever the prettyprinter tries to look up a symbol that
1507    is not currently defined in the toplevel environment but which
1508    appears in CM's autoload registry.  As a result, we see far fewer of
1509    those ?.Foo.Bar.xxx names in the prettyprinter's output.
1510    
1511    In addition to this I tried to clean up some pieces of the Basis
1512    implementation (e.g., Socket, Word8Array) in order to prevent other
1513    instances of these ?.Foo.Bar.xxx names from being printed.
1514    
1515    The mechanism that picks names for types still needs some work, though.
1516    (Right now it seems that if there is a type A.t which is defined to
1517    be B.u, but B is unavailable at toplevel, then A.t gets printed as
1518    "?.B.u" although the perhaps more sensible solution would be to use
1519    "A.t" in this case.  In other words, the prettyprinter should follow
1520    a chain of DEFtycs not farther than there are corresponding toplevel
1521    names in the current environment.)

1527    Description:
1528    
1529    Another installer tweak:  All the ML code for the installer is now
1530    compiled during CMB.make and put into a little library called
1531    $smlnj/installer.cm.  The installation then simply invokes
1532    
1533       sml -m $smlnj/installer.cm
1534    
1535    and everything happens automagically.
1536    
1537    Win32:  ML code senses value of environment variable SMLNJ_HOME.
1538    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
1539            and BINDIR.
1540    
1541    The new scheme guarantees that the ML code responsible for the installation
1542    is in sync with the APIs of the main system.  Also, the installer is
1543    somewhat faster because the installer script is precompiled.
