26    Tag: blume-20050516-redump-heap
27    Description:
28    
29    Added mechanism for re-creating a heap file for the interactive system
30    after configuration variables have been changed.
31    
32       CM.redump_heap : string -> unit
33    
34    This is much like SMLofNJ.exportML, but starting from the resulting
35    heap does not return to the caller of CM.redump_heap but
36    restarts the interactive system from scratch.  The original call of
37    CM.redump_heap does not return but ends the interactive session.
38    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
39    
40    Internally, redump_heap winds the dynamic execution context back to
41    the point where the original heap image was created and re-executes
42    the heap image generation code in the boot code.

48    Description:
49    
50    Added a hack to the existing hack known as Word64 to make fromString
51    behave correctly.  I am still not sure whether Word64.scan will work
52    as specified with respect to the interaction of radix and prefix.

58    Description:
59    
60    Added a gc protocol checking phase.  This phase is enabled with
61    the flag "check-gc".  "debug-check-gc" turns on the verbose mode.

84    Description:
85    
86    Fixed serious bug (brown paper bag variety) in new implementation of
87    structure Atom in CML.  (I had accidentally used a mailbox instead of
88    an mvar, leaving the door open for races.)

101    Tag: blume-20050225-susp
102    Description:
103    
104    Brought back SMLofNJ.Susp.  The underlying suspension type is the one
105    implemented in Core -- which means that it is the same as the one used
106    by the lazy extension.

129    Tag: blume-20050210-longlong
130    Description:
131    
132    Implemented "long long" arguments and results for NLFFI.  (Only the
133    PPC/MacOS implementation is complete, the other backends still need to
134    be updated.)

139    Tag: blume-20050124-mlyacc
140    Description:
141    
142    Minor cleanup in ML-Yacc rule printing mechanism.  This should fix a
143    problem with certain "as" patterns which previously got rendered
144    using incorrect syntax.
145

149    Tag: blume-20050118-profile
150    Description:
151    
152    Made time profiling code (interrupt handler) in runtime system aware
153    of new array representation.
154

158    Tag: blume-20050114-heap2exec
159    Description:
160    
161    Implemented new (but still experimental) heap2exec facility.  This is
162    tested under Mac OS X and should work under Linux (will test shortly).
163    It will probably also work on the Sparc (will test some time later).
164    
165      - removed old "HACKED_STANDALONE" hack from runtime
166    
167    To be able to test this, uncomment the request for "heap2asm" in
168    config/targets prior to installation.  (Notice that this is different
169    from "heap2exec" mentioned below.  Not a typo.)
170    
171    To perform an actual test, run the command
172    
173       $ bin/heap2exec heapfile execfile
174    
175    (You can put heap2exec on your shell's path.)
176    
177    For example, run
178    
179      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
180    
181    This will create a standalone executable called "mly" which you can
182    then invoke directly as a command.

202    Date: 2004/12/21 15:05:00 CST
203    Tag: blume-20041221-longlong
204    Description:
205    
206    * Implemented access to signed and unsigned long long data in NLFFI.
207    (The parameter-passing part of the picture has not complete. But
208    data structure access seems to work.)
209    
210    * Fixed CM's incorrect assumption that the PPC is little-endian.
211      (On the Mac, it is big-endian.  And that's currently our only
212      PPC platform.)

217    Tag: blume-20041221-memory
218    Description:
219    
220    Some cleanup in the $c/memory.cm library: separated some concerns by
221    moving allocation code and memory access code each into their own
222    files.

227    Tag: leunga-20041217-cygwin-smlnj-home
228    Description:
229    
230        The Unix I/O library of SML/NJ on cygwin does not understand
231    Windows style pathname, so problems arise when SMLNJ_HOME is set
232    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
233    to a POSIX pathname on cygwin.

252    
253    - HashString.hashString' -> HashString.hashSubstring
254    - corresponding changes in atom.sml
255    - "de-compressed" (aka. un-obfuscated) code for UnivariateStats and
256      added some comments

277    Tag: blume-20041214-spaces
278    Description:
279    
280    Hacked some of the scripts (in particular: the installer) to cope with
281    spaces in filenames a bit better.  But beware: the current "solution"
282    is likely still full of bugs and inherently incomplete.  (We need to
283    do away with those shell scripts for a comprehensive solution.)

306    Description:
307    
308    smlnj-lib:
309    
310      Added function HashString.hashString' for substrings.
311      Hand-inlined CharVector.foldl into HashString (for speed).
312      Modified implementation of structure Atom to avoid extracting
313      strings from substrings unless necessary.
314      (Also see CHANGES file for smlnj-lib.)

319    Tag: blume-20041124-cml
320    Description:
321    
322    Made sure CML compiles when Position = Int64.

326    Date: 2004/11/24 14:30:00 CST
327    Tag: blume-20041124-position
328    Description:
329    
330    The compiler can now be compiled in a mode that makes structure Position
331    equal to Int64.  The default, however, is unchanged (Position = Int31)
332    for the time being.
333    
334    To enable 64-bit positions, use the following procedure:
335    
336    1. Start sml
337    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
338    3. Type
339          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
340    4. Run CMB.make() as usual.
341    
342    This is barely tested.  The only test so far was a little SML program
343    counting the number of characters in an 8-gigabyte file by
344    reading it character-by-character.  That test was successful.
345    
346    In support of 64-bit positions, a number of new functions have been
347    added to the runtime system.

387    Tag: blume-20041113-versiontool
388    Description:
389    
390    - Stripped down the versiontool: It now only handles the version number.
391      The date string is generated at bootstrap time (during makeml).
392    
393    - In a previous commit, fixed a minor issue with how polyequal is being
394      translated.  In particular, the code now "looks through" abstractions.
395      This results in slightly fewer polyEqual warnings and hopefully slightly
396      more efficient code.  Important examples for where this matters are
397      the new int64 and word64 types.

411    Tag: blume-20041111-more64
412    Description:
413    
414    All the pieces of Word64 are now there, with the exception of the
415    conversions from and to LargeWord. (Eventually these need to be identities,
416    but for the time being they don't even make sense because LargeWord is
417    32-bit wide.)
418    
419    Also started to add similar support for Int64, but major pieces of that
420    are still missing.
421

425    Tag: blume-20041111-word64
426    Description:
427    
428    Structure Word64 is now (almost) complete, word literals and patterns
429    seem to work.  There are a few odd pieces missing.  In particular,
430    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
431    at the moment.
432    
433    Making Word64 official would mean that LargeWord becomes Word64.  But
434    this requires extreme care because most word-word conversions have to
435    go through LargeWord, so making a mistake means loss of efficiency or
436    worse.  Eventually there will be a solution similar to (but actually
437    simpler than) what I did with IntInf.

470        containing the URL string into a file containing
471        shell script code.  The code has access to the $VERSION variable.
472      - Made corresponding changes to config/install.sh and config/unpack.
473      - Default contents of config/srcarchiveurl uses $VERSION and
474        normally does not have to be edited to reflect a version change.
475    
476      (As a result, a version change can be done by just editing
477       config/version, the rest is now automatic.)

517    Tag: blume-20041020-standalone-backtrace
518    Description:
519    
520    Added a mechanism for getting back-trace information from standalone
521    programs.  Here is how it works:
522    
523       1. The part of the program from which you want to get backtrace
524          information (usually the whole program) should be wrapped with
525          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
526          main program could be modified from something like
527    
528             fun main (pgm, args) = ...
529    
530         to
531    
532            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
533    
534       2. To be able to access BackTrace.monitor, you have to add
535          library $smlnj-tdp/plugins.cm to the .cm file that contains your
536          main function.
537    
538       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
539          CM might have created in the past for your project).
540    
541       4. Build the system using this command line:
542    
543             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
544                      myprog.cm MyProg.main myprog
545    
546          instead of the usual
547    
548             ml-build myprog.cm MyProg.main myprog
549    
550    I changed a library name:
551    
552       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
553    
554    New libraries:
555    
556       $smlnj-tdp/back-trace.cm
557          -- when loaded causes the back-trace plugin to be installed
558       $smlnj-tdp/coverage.cm
559          -- when loaded causes the coverage plugin to be installed

575    Description:
576    
577    * Test coverage tool added!
578    * Further reorganization of tracing-, debugging-, and profiling support:
579    
580        - moved original BTImp -- now called BackTrace -- into a separate
581          library called $/trace-debug-profile.cm
582        - eliminated all mentions of BTrace from SMLofNJ.Internals
583        - only the instrumentation mechanism is now left in the compiler proper
584        - BackTrace module is a plugin which is NOT plugged in by default
585        - Coverage module is another such plugin
586    
587    To get the benefits of any of these plugin modules, the code in
588    question must be compiled with tdp instrumentation turned on.  This
589    can be done by setting SMLofNJ.Internals.TDP.mode to true.
590    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
591    
592    Plugins are selected at link time.  (Pre-compiled instrumented code
593    can be re-loaded with different plugins in effect.)  When an
594    instrumented module is linked, whatever plugins are at that time
595    enabled will come into effect for that module.
596    
597    To enable the back-trace plugin, load library $/trace-debug-profile.cm
598    and invoke BackTrace.install() (e.g., from the interactive prompt).
599    To enable the coverage plugin, load the same library and invoke
600    Coverage.install().
601    
602    Back-traces are generated automatically on uncaught exceptions and
603    when the code in question explicitly invokes BackTrace.trigger().
604    
605    Coverage (and execution frequency-) information must be queried
606    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

623    Some rationalization of names:

628    This is is preparation of using the original back-trace
629    instrumentation for other purposes.  "TDP" stands for
630    Trace/Debug/Profile.
631    
632    The control flag controlling whether instrumentation is on or off is now
633    registered under a different name, so instead of running sml as
634    
635     sml -Cinstrument.btrace-mode=true
636    
637    one has to say
638    
639     sml -Ctdp.instrument=true

657    Fixed handling of keywords in .cm files: After seeing "is" the lexer
658    treats subsequent occurrences of "group", "library", "source", "is",
659    "*", and "-" as ordinary identifiers rather than keywords.
660    
661    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
662    is supposed to accept a tool argument called "source", but this did
663    not work because of the clash with the keyword.

708    * Moved the "version" magic into its own little library under

713      structure SMLNJVersion.

715    * Arranged for the version tool to NOT kick in when rebuilding the system
716      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
717      Also, loading the versiontool does not work when rebuilding the system
718      because CM is not properly initialized at that time.

723    Tag: blume-20040929-autoversion
724    Description:
725    
726    Implemented some CM magic to have
727        file src/compiler/TopLevel/main/version.sml
728    generated automagically.
729    The version is taken from two files: config/version and config/release.
730    The first is expected to contain a two-part version number such as 110.49.
731    The second should contain a single number, but it may be missing.
732    
733    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
734    time the version tool is loaded (which is the first time you say CMB.make),
735    then the tool will increment the value stored in config/release every
736    time CMB.make is invoked.
737    
738    The binfile format is now insensitive to anything beyond the first
739    two components of a version number, so bumping the release does not render
740    binfiles incompatible.  Auto-bumping can be used to keep track of versions
741    during development without invalidating existing binfiles.
742    
743    In any case, every CMB.make updates the date information in version.sml.
744    (This is the date that is printed in the banner.)

758    Description:
759    
760    Added two pieces of functionality to the Controls interface:
761    
762    1.   val save'restore: 'a control -> unit -> unit
763    
764       grabs the current value of the control in stage 1 and restores it
765       in stage 2.
766    
767    2.   val set' : 'a control * 'a -> unit -> unit
768    
769       stores the given value into the control in stage 2 (i.e., delayed)
770       but does all error checking in stage 1.
771       (This is for string controls that need to do parse their argument --
772        something that might fail.  In some cases, notably in CM, one
773        already knows the intended argument but wants to delay the actual
774        assignment until a time when error recovery would be more difficult.)
775    
776    Changed the handling of controls in tool arguments to classes "sml" and
777    "lazysml":
778       - use Controls.save'restore as a more robust way of restoring the
779         old value (in particular: without having to re-parse the string)
780       - use controls to handle the "overload" keyword in the init group
781         (I believe this change actually fixes a long-standing obscure bug.)

786    Tag: blume-20040927-lazysml
787    Description:
788    
789    Added a new tool class called "lazysml" to CM's tool chest.  The only
790    difference to "sml" is that compilation is done with Control.lazysml
791    set to true.  A source of class "lazysml" is automatically recognized
792    by a file name suffix of ".lml".
793    
794    In addition to the above feature, the original class "sml" now also
795    supports a tool argument "lazy" which has the same effect.  As a
796    result, the following three lines are equivalent:
797    
798        foo.sml : lazysml
799        foo.sml : sml (lazy)
800        foo.sml (lazy)
801    
802    The setting goes into effect both during parsing and during
803    compilation.  The original setting is restored right after parsing and
804    after compilation, respectively.
805    
806    In addition to all the above, there is also a general mechanism to set
807    ANY of the "controls" that are available at the command line via
808    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
809    apply as well. (In fact, "lazy" is implemented as a special case of
810    the general mechanism.)
811    
812    The .cm file syntax uses a new keyword tool argument called "with".
813    There are several ways of indicating the desired settings:
814    
815        foo.sml (with:parser.quotations=true)
816        foo.sml (with:(name:parser.quotations value:true))
817        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
818        foo.sml (with:(name1=value1 name2=value2 ...))
819        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
820    
821        etc.
822    
823    Another possible abbreviation is to leave out the =v or value:v part
824    if the name refers to a boolean control (in which case the value is
825    taken to be true).  Thus, one could get lazy sml also by saying:
826    
827        foo.sml (with:parser.lazy-keyword=true)
828        foo.sml (with:parser.lazy-keyword)
829        foo.sml (with:(name:parser.lazy-keyword value:true))
830        foo.sml (with:(name:parser.lazy-keyword))

925    
926    - improved ML code of installer to fall back to coping when renaming
927      fails (i.e., when source and target are on different file systems);
928      the code compiles but has yet to be tested in anger
929    - removed mlrisc from list of default targets (config/targets)

1182    Description:
1183    
1184    Changed the interface of structures Timer and Unix to match the most
1185    recent Basis spec.
1186    
1187    In the case of Unix there still seems to be an open/weird issue:
1188    
1189       The {text,bin}{In,Out}streamOf functions are supposed to create
1190       fresh streams whenever they are called -- as opposed to have them
1191       return the same stream every time.  This design is supposed to
1192       prevent space leaks caused by proc values hanging on to streams.
1193    
1194       The reap function, on the other hand, is supposed to close the
1195       streams.  This cannot be done without having a handle on the
1196       stream in proc after all...
1197    
1198    I took the liberty to implement the following stopgap solution:
1199    
1200      The proc value hangs on to the most recently created stream(s).
1201      Reap closes those.  If either or both of the two streams hadn't
1202      been created at all yet, then reap will close the corresponding
1203      file descriptors directly.
1204    
1205    PS: I don't understand the original space leak argument anymore.  If
1206    a proc hangs on to the imperative stream, then I/O operations on those
1207    will advance the state of the cached stream and avoid the space leak.

1221    Description:
1222    
1223    CM now ignores (but still accepts) the "owner" information in group
1224    descriptions.  The owner of a group is its next enclosing
1225    library. Each group must have a unique owner.  (There is a virtual
1226    "toplevel" library that owns groups which are not nested within a real
1227    library.)  Previously, each group had to explicitly declare its owner,
1228    and CM would check that such a declaration is correct.  The new scheme
1229    is to have CM check that for each group there is precisely one owning
1230    library.
1231    
1232    The advantage of the new scheme is that the programmer no longer needs
1233    to maintain the somewhat annoying owner information.  The downside is
1234    that CM cannot enforce the ownership rule across multiple runs of
1235    CM.make.  Fortunately, enclosing the same group in two different
1236    libraries A and B which are not part of the same program does not
1237    cause real problems.

1258    Arranged for ml-build to clean up after itself a little bit better.
1259    The script generates a temporary SML source file and compiles it using
1260    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
1261    gets rid of those at the end, so they don't accumulate under .cm.
1262    
1263    This required a minor change to install.sh because the name of the
1264    metadata directory (default: .cm) is actually configurable at
1265    installation time.

1281    
1282    Added previously missing support for many socket-related functions
1283    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
1284    for the voluminous patch!
1285    
1286    (I have not tested this patch under win32 yet.)
1287    
1288    Here is David's e-mail:
1289    
1290    Hi,
1291    
1292    Attached to this email you find a diff against sml/nj 110.45
1293    that will enable socket support under Windows.
1294    
1295    To apply the patch (using unix or cygwin)
1296    1) gunzip runtime.diff.gz
1297    2) "cd" into "src/runtime" in the source tree of a fresh
1298       110.45 installation.
1299    3) patch -p 1 < [your/path/to]runtime.diff
1300    
1301    The code compiles fine but has NOT yet been extensively tested.
1302    I only ran a few tests for basic socket client functionality
1303    (which worked fine).  Especially the functions that use ioctl
1304    are not tested at all and might not work (see below).
1305    
1306    I implemented this since we want to move to a newer version of sml/nj
1307    but need socket support in order to use it.  This is the first time I
1308    even had a look at the sml/nj source,  so please review my changes
1309    before making this part of the distribution!  Here are a few issues
1310    that I think might be better for someone to solve who is more
1311    familiar with the sml/nj source (and socket programming):
1312    
1313    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1314      exception since I could not figure out what the windows equivalent
1315      of these functions is
1316    
1317    - In sockets-osdep.h there are a some #include statements that are
1318      only used in a few files that include sockets-osdep.h
1319    
1320    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1321      does not process its return value since I don't know how to
1322      report an error upwards.
1323    
1324    - It would probably be good to have a call to WSACleanup() when
1325      the library is unloaded (if there is such a possibility).
1326      Otherwise I think Windows will take care of this automatically
1327      when the process finishes.
1328    
1329    - I used ioctlsocket() as a replacement for ioctl() but I have
1330      no idea if that is actually the proper replacement on Windows.
1331    
1332    - All these issues are marked in the code by "FIXME" comments.
1333    
1334    We use sml/nj extensively in our products and are quite happy
1335    with it.  I hope this contribution will help you.
1336    
1337    Keep up the good work!
1338

1372    Description:
1373    
1374    The installer now honors the "src-smlnj" target again, although its meaning
1375    has changed from "all sources required for the compiler" to "all sources
1376    the installer knows about".  In other words, if you enable "src-smlnj"
1377    in the "targets" file, then the installer will pull in sources for
1378    everything.  (Notice that this refers to source code only.  Compiled
1379    code is still only installed for modules that were requested explicitly
1380    or which are required for other modules that were requested explicitly.)

1386    Description:
1387    
1388    Fixed IEEEReal.scan (and .fromString) so that if there is an overflow
1389    in the exponent calculation we get INF or ZERO (depending on the mantissa
1390    and the sign of the exponent).

1414    Description:
1415    
1416    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
1417    of SML/NJ.  The problem is that
1418    
1419       lib = dlopen(NULL, ...)
1420       f   = dlsym(lib, "malloc");
1421    
1422    does not work on Windows unless we explicitly export symbols
1423    such as 'malloc' during linking.  We fixed this by explicitly
1424    exporting the required symbols with the magic gcc incantation:
1425    
1426        -Wl,--export-all cygwin.def
1427    
1428    where cygwin.def is a file containing all the symbols that
1429    we wish to export.
1430    
1431    I suspect this is a Windows problem and we'll have to
1432    do the same (somehow with windows compilers) when
1433    we build the native win32 version with the system
1434    calls LoadLibrary/GetProcAddress.

1441    
1442    Fixed problem with IntInf.fmt (sign would show up on the right instead
1443    of on the left for BIN, OCT, and HEX).

1449    Description:
1450    
1451    Fixed problem with installer script (unix only) where bin/ml-yacc and
1452    friends pointed (via symlinks) to absolute locations instead of just
1453    .run-sml.  This was reported by Vesa A Norrman.
