35    Description:
36    
37    Hacked some of the scripts (in particular: the installer) to cope with
38    spaces in filenames a bit better.  But beware: the current "solution"
39    is likely still full of bugs and inherently incomplete.  (We need to
40    do away with those shell scripts for a comprehensive solution.)

65    smlnj-lib:
66    
67      Added function HashString.hashString' for substrings.
68      Hand-inlined CharVector.foldl into HashString (for speed).
69      Modified implementation of structure Atom to avoid extracting
70      strings from substrings unless necessary.

77    Description:
78    
79    Made sure CML compiles when Position = Int64.

82    Name: Matthias Blume (blume (at) tti - c (dot) org)
83    Date: 2004/11/24 14:30:00 CST
84    Tag: blume-20041124-position
85    Description:
86    
87    The compiler can now be compiled in a mode that makes structure Position
88    equal to Int64.  The default, however, is unchanged (Position = Int31)
89    for the time being.
90    
91    To enable 64-bit positions, use the following procedure:
92    
93    1. Start sml
94    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
95    3. Type
96          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
97    4. Run CMB.make() as usual.
98    
99    This is barely tested.  The only test so far was a little SML program
100    counting the number of characters in an 8-gigabyte file by
101    reading it character-by-character.  That test was successful.
102    
103    In support of 64-bit positions, a number of new functions have been
104    added to the runtime system.

110    Description:
111    
112    Fixed a problem with unhelpful error messages related to problems with
113    .cm- or .sml files that appear as part of the sml command line.

144    Tag: blume-20041113-versiontool
145    Description:
146    
147    - Stripped down the versiontool: It now only handles the version number.
148      The date string is generated at bootstrap time (during makeml).
149    
150    - In a previous commit, fixed a minor issue with how polyequal is being
151      translated.  In particular, the code now "looks through" abstractions.
152      This results in slightly fewer polyEqual warnings and hopefully slightly
153      more efficient code.  Important examples for where this matters are
154      the new int64 and word64 types.
155

160    Description:
161    
162    Structure Int64 fully hooked in.  (The implementation is not very
163    efficient, though.)

168    Tag: blume-20041111-more64
169    Description:
170    
171    All the pieces of Word64 are now there, with the exception of the
172    conversions from and to LargeWord. (Eventually these need to be identities,
173    but for the time being they don't even make sense because LargeWord is
174    32-bit wide.)
175    
176    Also started to add similar support for Int64, but major pieces of that
177    are still missing.
178    
179    ----------------------------------------------------------------------
180    Name: Matthias Blume (blume (at) tti - c (dot) org)
181    Date: 2004/11/11 00:15:00 CST
182    Tag: blume-20041111-word64
183    Description:
184    
185    Structure Word64 is now (almost) complete, word literals and patterns
186    seem to work.  There are a few odd pieces missing.  In particular,
187    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
188    at the moment.
189    
190    Making Word64 official would mean that LargeWord becomes Word64.  But
191    this requires extreme care because most word-word conversions have to
192    go through LargeWord, so making a mistake means loss of efficiency or
193    worse.  Eventually there will be a solution similar to (but actually
194    simpler than) what I did with IntInf.

200    Description:
201    
202    More 64-bit hacking (but still not even half-way there yet).
203    Also, some assorted improvements to the handling of 8-bit words.

209    Description:
210    
211    Started adding some infrastructure for supporting 64-bit int- and
212    word-types.  (Still in its very early stages.)

217    Tag: Release_110_50
218    Description:
219    
220    New working version (110.50).  NEW BOOTFILES!
221    
222                 =====================
223    
224    Also:
225    
226      - Changend config/srcarchiveurl from a file just
227        containing the URL string into a file containing
228        shell script code.  The code has access to the $VERSION variable.
229      - Made corresponding changes to config/install.sh and config/unpack.
230      - Default contents of config/srcarchiveurl uses $VERSION and
231        normally does not have to be edited to reflect a version change.
232    
233      (As a result, a version change can be done by just editing
234       config/version, the rest is now automatic.)

249    Description:
250    
251    This is the HISTORY entry for two earlier commits, both concerning
252    the x86 c-calls code in MLRISC:
253    
254      - added a missing LOAD in the code that deals with struct arguments
255      - made sure the caller does not add the wrong number of bytes to the
256        stack pointer after a call of a function returning a struct
257        (the callee already pops the implicit argument which points to
258         the space reserved for the result)

265    
266       John discovered a bug in the syntax of fucomip.
267       The opcodes FU?COMIP? have been changed to

274    Tag: blume-20041020-standalone-backtrace
275    Description:
276    
277    Added a mechanism for getting back-trace information from standalone
278    programs.  Here is how it works:
279    
280       1. The part of the program from which you want to get backtrace
281          information (usually the whole program) should be wrapped with
282          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
283          main program could be modified from something like
284    
285             fun main (pgm, args) = ...
286    
287         to
288    
289            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
290    
291       2. To be able to access BackTrace.monitor, you have to add
292          library $smlnj-tdp/plugins.cm to the .cm file that contains your
293          main function.
294    
295       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
296          CM might have created in the past for your project).
297    
298       4. Build the system using this command line:
299    
300             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
301                      myprog.cm MyProg.main myprog
302    
303          instead of the usual
304    
305             ml-build myprog.cm MyProg.main myprog
306    
307    I changed a library name:
308    
309       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
310    
311    New libraries:
312    
313       $smlnj-tdp/back-trace.cm
314          -- when loaded causes the back-trace plugin to be installed
315       $smlnj-tdp/coverage.cm
316          -- when loaded causes the coverage plugin to be installed
317

326    Eliminated group owner specs from .cm files throughout the source tree.

331    Tag: blume-20041015-coverage
332    Description:
333    
334    * Test coverage tool added!
335    * Further reorganization of tracing-, debugging-, and profiling support:
336    
337        - moved original BTImp -- now called BackTrace -- into a separate
338          library called $/trace-debug-profile.cm
339        - eliminated all mentions of BTrace from SMLofNJ.Internals
340        - only the instrumentation mechanism is now left in the compiler proper
341        - BackTrace module is a plugin which is NOT plugged in by default
342        - Coverage module is another such plugin
343    
344    To get the benefits of any of these plugin modules, the code in
345    question must be compiled with tdp instrumentation turned on.  This
346    can be done by setting SMLofNJ.Internals.TDP.mode to true.
347    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
348    
349    Plugins are selected at link time.  (Pre-compiled instrumented code
350    can be re-loaded with different plugins in effect.)  When an
351    instrumented module is linked, whatever plugins are at that time
352    enabled will come into effect for that module.
353    
354    To enable the back-trace plugin, load library $/trace-debug-profile.cm
355    and invoke BackTrace.install() (e.g., from the interactive prompt).
356    To enable the coverage plugin, load the same library and invoke
357    Coverage.install().
358    
359    Back-traces are generated automatically on uncaught exceptions and
360    when the code in question explicitly invokes BackTrace.trigger().
361    
362    Coverage (and execution frequency-) information must be queried
363    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

369    Description:
370    
371    Snapshot of a significant overhaul of how the trace/debug/profile support
372    is hooked into the system (specifically: Core and SMLofNJ.Internals).

378    Description:
379    
380    Some rationalization of names:
381    
382       structure BTrace -> structure TDPInstrument
383       etc.
384    
385    This is is preparation of using the original back-trace
386    instrumentation for other purposes.  "TDP" stands for
387    Trace/Debug/Profile.
388    
389    The control flag controlling whether instrumentation is on or off is now
390    registered under a different name, so instead of running sml as
391    
392     sml -Cinstrument.btrace-mode=true
393    
394    one has to say
395    
396     sml -Ctdp.instrument=true

402    Description:
403    
404    Made some minor modifications to elabcore.sml to have source regions

406    regions being reported in error- and debug messages.

411    Tag: blume-20041008-cmkw
412    Description:
413    
414    Fixed handling of keywords in .cm files: After seeing "is" the lexer
415    treats subsequent occurrences of "group", "library", "source", "is",
416    "*", and "-" as ordinary identifiers rather than keywords.
417    
418    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
419    is supposed to accept a tool argument called "source", but this did
420    not work because of the clash with the keyword.

427    
428    Assorted cleanup work:
429    
430      - got rid of intstrmap in favor of using the library's
431        hash table implementation
432      - threw out most of the pathnames stuff, as it was not used anyway
433      - simplified tokentable implementation
434      - fixed some minor spelling errors

441    
442    Cleaned up the absyn to reflect the invariant that HANDLE always
443    carries a FNexp as part of the type definition.  This eliminates some

452    Description:
453    
454    Added hack to make slave mode work in the presence of the version
455    tool.  (Still, since the master does two passes over the code for
456    CMB.make, the release number gets bumped twice when slaves are
457    attached.  I don't know if this is worth fixing...)

462    Tag: blume-20040930-version
463    Description:
464    
465    * Moved the "version" magic into its own little library under
466      src/system/smlnj/internal.  This avoids expensive reconstruction of
467      a stable src/compiler/core.cm.
468    
469    * At the same time, structure CompilerVersion is now known as
470      structure SMLNJVersion.
471    
472    * Arranged for the version tool to NOT kick in when rebuilding the system
473      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
474      Also, loading the versiontool does not work when rebuilding the system
475      because CM is not properly initialized at that time.

481    Description:
482    
483    Implemented some CM magic to have
484        file src/compiler/TopLevel/main/version.sml
485    generated automagically.
486    The version is taken from two files: config/version and config/release.
487    The first is expected to contain a two-part version number such as 110.49.
488    The second should contain a single number, but it may be missing.
489    
490    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
491    time the version tool is loaded (which is the first time you say CMB.make),
492    then the tool will increment the value stored in config/release every
493    time CMB.make is invoked.
494    
495    The binfile format is now insensitive to anything beyond the first
496    two components of a version number, so bumping the release does not render
497    binfiles incompatible.  Auto-bumping can be used to keep track of versions
498    during development without invalidating existing binfiles.
499    
500    In any case, every CMB.make updates the date information in version.sml.
501    (This is the date that is printed in the banner.)

514    Tag: blume-20040927-controls
515    Description:
516    
517    Added two pieces of functionality to the Controls interface:
518    
519    1.   val save'restore: 'a control -> unit -> unit
520    
521       grabs the current value of the control in stage 1 and restores it
522       in stage 2.
523    
524    2.   val set' : 'a control * 'a -> unit -> unit
525    
526       stores the given value into the control in stage 2 (i.e., delayed)
527       but does all error checking in stage 1.
528       (This is for string controls that need to do parse their argument --
529        something that might fail.  In some cases, notably in CM, one
530        already knows the intended argument but wants to delay the actual
531        assignment until a time when error recovery would be more difficult.)
532    
533    Changed the handling of controls in tool arguments to classes "sml" and
534    "lazysml":
535       - use Controls.save'restore as a more robust way of restoring the
536         old value (in particular: without having to re-parse the string)
537       - use controls to handle the "overload" keyword in the init group
538         (I believe this change actually fixes a long-standing obscure bug.)

543    Tag: blume-20040927-lazysml
544    Description:
545    
546    Added a new tool class called "lazysml" to CM's tool chest.  The only
547    difference to "sml" is that compilation is done with Control.lazysml
548    set to true.  A source of class "lazysml" is automatically recognized
549    by a file name suffix of ".lml".
550    
551    In addition to the above feature, the original class "sml" now also
552    supports a tool argument "lazy" which has the same effect.  As a
553    result, the following three lines are equivalent:
554    
555        foo.sml : lazysml
556        foo.sml : sml (lazy)
557        foo.sml (lazy)
558    
559    The setting goes into effect both during parsing and during
560    compilation.  The original setting is restored right after parsing and
561    after compilation, respectively.
562    
563    In addition to all the above, there is also a general mechanism to set
564    ANY of the "controls" that are available at the command line via
565    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
566    apply as well. (In fact, "lazy" is implemented as a special case of
567    the general mechanism.)
568    
569    The .cm file syntax uses a new keyword tool argument called "with".
570    There are several ways of indicating the desired settings:
571    
572        foo.sml (with:parser.quotations=true)
573        foo.sml (with:(name:parser.quotations value:true))
574        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
575        foo.sml (with:(name1=value1 name2=value2 ...))
576        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
577    
578        etc.
579    
580    Another possible abbreviation is to leave out the =v or value:v part
581    if the name refers to a boolean control (in which case the value is
582    taken to be true).  Thus, one could get lazy sml also by saying:
583    
584        foo.sml (with:parser.lazy-keyword=true)
585        foo.sml (with:parser.lazy-keyword)
586        foo.sml (with:(name:parser.lazy-keyword value:true))
587        foo.sml (with:(name:parser.lazy-keyword))

920    Description:
921    
922    Changed the implementation of structure Unix so that the same stream
923    is returned every time one of the {text,bin}{In,Out}streamOf functions
924    is invoked on the same proc.  This is not what the spec currently
925    says -- although IMO it arguably should.  (See discussion below.)

939    Description:
940    
941    Changed the interface of structures Timer and Unix to match the most
942    recent Basis spec.
943    
944    In the case of Unix there still seems to be an open/weird issue:
945    
946       The {text,bin}{In,Out}streamOf functions are supposed to create
947       fresh streams whenever they are called -- as opposed to have them
948       return the same stream every time.  This design is supposed to
949       prevent space leaks caused by proc values hanging on to streams.
950    
951       The reap function, on the other hand, is supposed to close the
952       streams.  This cannot be done without having a handle on the
953       stream in proc after all...
954    
955    I took the liberty to implement the following stopgap solution:
956    
957      The proc value hangs on to the most recently created stream(s).
958      Reap closes those.  If either or both of the two streams hadn't
959      been created at all yet, then reap will close the corresponding
960      file descriptors directly.
961    
962    PS: I don't understand the original space leak argument anymore.  If
963    a proc hangs on to the imperative stream, then I/O operations on those
964    will advance the state of the cached stream and avoid the space leak.

977    Tag: blume-20040525-group-owner
978    Description:
979    
980    CM now ignores (but still accepts) the "owner" information in group
981    descriptions.  The owner of a group is its next enclosing
982    library. Each group must have a unique owner.  (There is a virtual
983    "toplevel" library that owns groups which are not nested within a real
984    library.)  Previously, each group had to explicitly declare its owner,
985    and CM would check that such a declaration is correct.  The new scheme
986    is to have CM check that for each group there is precisely one owning
987    library.
988    
989    The advantage of the new scheme is that the programmer no longer needs
990    to maintain the somewhat annoying owner information.  The downside is
991    that CM cannot enforce the ownership rule across multiple runs of
992    CM.make.  Fortunately, enclosing the same group in two different
993    libraries A and B which are not part of the same program does not
994    cause real problems.

1013    Description:
1014    
1015    Arranged for ml-build to clean up after itself a little bit better.
1016    The script generates a temporary SML source file and compiles it using
1017    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
1018    gets rid of those at the end, so they don't accumulate under .cm.
1019    
1020    This required a minor change to install.sh because the name of the
1021    metadata directory (default: .cm) is actually configurable at
1022    installation time.

1037    Description:
1038    
1039    Added previously missing support for many socket-related functions
1040    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
1041    for the voluminous patch!
1042    
1043    (I have not tested this patch under win32 yet.)
1044    
1045    Here is David's e-mail:
1046    
1047    Hi,
1048    
1049    Attached to this email you find a diff against sml/nj 110.45
1050    that will enable socket support under Windows.
1051    
1052    To apply the patch (using unix or cygwin)
1053    1) gunzip runtime.diff.gz
1054    2) "cd" into "src/runtime" in the source tree of a fresh
1055       110.45 installation.
1056    3) patch -p 1 < [your/path/to]runtime.diff
1057    
1058    The code compiles fine but has NOT yet been extensively tested.
1059    I only ran a few tests for basic socket client functionality
1060    (which worked fine).  Especially the functions that use ioctl
1061    are not tested at all and might not work (see below).
1062    
1063    I implemented this since we want to move to a newer version of sml/nj
1064    but need socket support in order to use it.  This is the first time I
1065    even had a look at the sml/nj source,  so please review my changes
1066    before making this part of the distribution!  Here are a few issues
1067    that I think might be better for someone to solve who is more
1068    familiar with the sml/nj source (and socket programming):
1069    
1070    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1071      exception since I could not figure out what the windows equivalent
1072      of these functions is
1073    
1074    - In sockets-osdep.h there are a some #include statements that are
1075      only used in a few files that include sockets-osdep.h
1076    
1077    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1078      does not process its return value since I don't know how to
1079      report an error upwards.
1080    
1081    - It would probably be good to have a call to WSACleanup() when
1082      the library is unloaded (if there is such a possibility).
1083      Otherwise I think Windows will take care of this automatically
1084      when the process finishes.
1085    
1086    - I used ioctlsocket() as a replacement for ioctl() but I have
1087      no idea if that is actually the proper replacement on Windows.
1088    
1089    - All these issues are marked in the code by "FIXME" comments.
1090    
1091    We use sml/nj extensively in our products and are quite happy
1092    with it.  I hope this contribution will help you.
1093    
1094    Keep up the good work!
1095

1134    in the "targets" file, then the installer will pull in sources for
1135    everything.  (Notice that this refers to source code only.  Compiled
1136    code is still only installed for modules that were requested explicitly
1137    or which are required for other modules that were requested explicitly.)

1171    Description:
1172    
1173    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
1174    of SML/NJ.  The problem is that
1175    
1176       lib = dlopen(NULL, ...)
1177       f   = dlsym(lib, "malloc");
1178    
1179    does not work on Windows unless we explicitly export symbols
1180    such as 'malloc' during linking.  We fixed this by explicitly
1181    exporting the required symbols with the magic gcc incantation:
1182    
1183        -Wl,--export-all cygwin.def
1184    
1185    where cygwin.def is a file containing all the symbols that
1186    we wish to export.
1187    
1188    I suspect this is a Windows problem and we'll have to
1189    do the same (somehow with windows compilers) when
1190    we build the native win32 version with the system
1191    calls LoadLibrary/GetProcAddress.

1317    Description:
1318    
1319    I modified the read-eval-print loop so that the autoloader gets
1320    invoked whenever the prettyprinter tries to look up a symbol that
1321    is not currently defined in the toplevel environment but which
1322    appears in CM's autoload registry.  As a result, we see far fewer of
1323    those ?.Foo.Bar.xxx names in the prettyprinter's output.
1324    
1325    In addition to this I tried to clean up some pieces of the Basis
1326    implementation (e.g., Socket, Word8Array) in order to prevent other
1327    instances of these ?.Foo.Bar.xxx names from being printed.
1328    
1329    The mechanism that picks names for types still needs some work, though.
1330    (Right now it seems that if there is a type A.t which is defined to
1331    be B.u, but B is unavailable at toplevel, then A.t gets printed as
1332    "?.B.u" although the perhaps more sensible solution would be to use
1333    "A.t" in this case.  In other words, the prettyprinter should follow
1334    a chain of DEFtycs not farther than there are corresponding toplevel
1335    names in the current environment.)

1349    and everything happens automagically.
1350    
1351    Win32:  ML code senses value of environment variable SMLNJ_HOME.
1352    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
1353            and BINDIR.
1354    
1355    The new scheme guarantees that the ML code responsible for the installation
1356    is in sync with the APIs of the main system.  Also, the installer is
1357    somewhat faster because the installer script is precompiled.

1363    Description:
1364    
1365    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
1366    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
1367    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
1368    implementations of non-blocking operations from CML's Socket
1369    structure.

1375    Description:
1376    
1377    1. Fixed SOCKET API and implementation to match Basis spec.
1378       This required changing the internal representation of sockets to one
1379       that remembers (for each socket file descriptor) whether it is currently
1380       blocking or non-blocking.  This state is maintained lazily (i.e., a system
1381       call is made only if the state actually needs to change).
1382    
1383    2. OS-specific details of sockets were moved into separate files, thus
1384       making it possible to unify the bulk of the socket implementations
1385       between Unix and Win32.
1386    
1387    3. CML's socket API changed accordingly.
1388       (Note that we need to remove non-blocking functions from this API
1389       since they are redundant in the case of CML!)
1390    
1391    4. CML's socket implementation now makes use of non-blocking functions
1392       provided by Basis, thus removing all OS-dependent code from this part
1393       of CML.
1394    
1395    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

1412    Description:
1413    
1414    1. new-install.sh -> install.sh
1415    2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
1416    3. tweaked installer so that another name instead of .cm can be chosen
1417       at install time (by setting the CM_DIR_ARC environment variable
1418       during installation); once installation is complete, the name is
1419       fixed

1436    Description:
1437    
1438    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
1439       this seems to be controversial at the moment) and used those in
1440       Posix.ProcEnv.times.
1441    
1442    2. Added Time.{from,to}Nanoseconds to Time.
1443    
1444    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
1445       For example, fromLargeInt never needs to look at more than 3 "big
1446       digits" to get its 53 bits of precision.

1452    Description:
1453    
1454    Added an entry to the primitive environment
1455    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
1456    added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
1457    
1458    Removed some of the "magic" constants in real64.sml and replaced them
1459    with code that generates these values from their corresponding
1460    integer counterparts.
1461    
1462    Made all(?) the slice-related changes to the Basis and made everything
1463    compile again...
