58    Description:
59    
60    Hacked some of the scripts (in particular: the installer) to cope with
61    spaces in filenames a bit better.  But beware: the current "solution"
62    is likely still full of bugs and inherently incomplete.  (We need to
63    do away with those shell scripts for a comprehensive solution.)

86    Description:
87    
88    smlnj-lib:
89    
90      Added function HashString.hashString' for substrings.
91      Hand-inlined CharVector.foldl into HashString (for speed).
92      Modified implementation of structure Atom to avoid extracting
93      strings from substrings unless necessary.

100    Description:
101    
102    Made sure CML compiles when Position = Int64.
103

105    Name: Matthias Blume (blume (at) tti - c (dot) org)
106    Date: 2004/11/24 14:30:00 CST
107    Tag: blume-20041124-position
108    Description:
109    
110    The compiler can now be compiled in a mode that makes structure Position
111    equal to Int64.  The default, however, is unchanged (Position = Int31)
112    for the time being.
113    
114    To enable 64-bit positions, use the following procedure:
115    
116    1. Start sml
117    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
118    3. Type
119          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
120    4. Run CMB.make() as usual.
121    
122    This is barely tested.  The only test so far was a little SML program
123    counting the number of characters in an 8-gigabyte file by
124    reading it character-by-character.  That test was successful.
125    
126    In support of 64-bit positions, a number of new functions have been
127    added to the runtime system.

133    Description:
134    
135    Fixed a problem with unhelpful error messages related to problems with
136    .cm- or .sml files that appear as part of the sml command line.

167    Tag: blume-20041113-versiontool
168    Description:
169    
170    - Stripped down the versiontool: It now only handles the version number.
171      The date string is generated at bootstrap time (during makeml).
172    
173    - In a previous commit, fixed a minor issue with how polyequal is being
174      translated.  In particular, the code now "looks through" abstractions.
175      This results in slightly fewer polyEqual warnings and hopefully slightly
176      more efficient code.  Important examples for where this matters are
177      the new int64 and word64 types.

185    Structure Int64 fully hooked in.  (The implementation is not very
186    efficient, though.)

191    Tag: blume-20041111-more64
192    Description:
193    
194    All the pieces of Word64 are now there, with the exception of the
195    conversions from and to LargeWord. (Eventually these need to be identities,
196    but for the time being they don't even make sense because LargeWord is
197    32-bit wide.)
198    
199    Also started to add similar support for Int64, but major pieces of that
200    are still missing.
201    
202    ----------------------------------------------------------------------
203    Name: Matthias Blume (blume (at) tti - c (dot) org)
204    Date: 2004/11/11 00:15:00 CST
205    Tag: blume-20041111-word64
206    Description:
207    
208    Structure Word64 is now (almost) complete, word literals and patterns
209    seem to work.  There are a few odd pieces missing.  In particular,
210    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
211    at the moment.
212    
213    Making Word64 official would mean that LargeWord becomes Word64.  But
214    this requires extreme care because most word-word conversions have to
215    go through LargeWord, so making a mistake means loss of efficiency or
216    worse.  Eventually there will be a solution similar to (but actually
217    simpler than) what I did with IntInf.

223    Description:
224    
225    More 64-bit hacking (but still not even half-way there yet).
226    Also, some assorted improvements to the handling of 8-bit words.

235    word-types.  (Still in its very early stages.)

241    Description:
242    
243    New working version (110.50).  NEW BOOTFILES!
244    
245                 =====================
246    
247    Also:
248    
249      - Changend config/srcarchiveurl from a file just
250        containing the URL string into a file containing
251        shell script code.  The code has access to the $VERSION variable.
252      - Made corresponding changes to config/install.sh and config/unpack.
253      - Default contents of config/srcarchiveurl uses $VERSION and
254        normally does not have to be edited to reflect a version change.
255    
256      (As a result, a version change can be done by just editing
257       config/version, the rest is now automatic.)

272    Description:
273    
274    This is the HISTORY entry for two earlier commits, both concerning
275    the x86 c-calls code in MLRISC:
276    
277      - added a missing LOAD in the code that deals with struct arguments
278      - made sure the caller does not add the wrong number of bytes to the
279        stack pointer after a call of a function returning a struct
280        (the callee already pops the implicit argument which points to
281         the space reserved for the result)

297    Tag: blume-20041020-standalone-backtrace
298    Description:
299    
300    Added a mechanism for getting back-trace information from standalone
301    programs.  Here is how it works:
302    
303       1. The part of the program from which you want to get backtrace
304          information (usually the whole program) should be wrapped with
305          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
306          main program could be modified from something like
307    
308             fun main (pgm, args) = ...
309    
310         to
311    
312            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
313    
314       2. To be able to access BackTrace.monitor, you have to add
315          library $smlnj-tdp/plugins.cm to the .cm file that contains your
316          main function.
317    
318       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
319          CM might have created in the past for your project).
320    
321       4. Build the system using this command line:
322    
323             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
324                      myprog.cm MyProg.main myprog
325    
326          instead of the usual
327    
328             ml-build myprog.cm MyProg.main myprog
329    
330    I changed a library name:
331    
332       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
333    
334    New libraries:
335    
336       $smlnj-tdp/back-trace.cm
337          -- when loaded causes the back-trace plugin to be installed
338       $smlnj-tdp/coverage.cm
339          -- when loaded causes the coverage plugin to be installed

354    Tag: blume-20041015-coverage
355    Description:
356    
357    * Test coverage tool added!
358    * Further reorganization of tracing-, debugging-, and profiling support:
359    
360        - moved original BTImp -- now called BackTrace -- into a separate
361          library called $/trace-debug-profile.cm
362        - eliminated all mentions of BTrace from SMLofNJ.Internals
363        - only the instrumentation mechanism is now left in the compiler proper
364        - BackTrace module is a plugin which is NOT plugged in by default
365        - Coverage module is another such plugin
366    
367    To get the benefits of any of these plugin modules, the code in
368    question must be compiled with tdp instrumentation turned on.  This
369    can be done by setting SMLofNJ.Internals.TDP.mode to true.
370    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
371    
372    Plugins are selected at link time.  (Pre-compiled instrumented code
373    can be re-loaded with different plugins in effect.)  When an
374    instrumented module is linked, whatever plugins are at that time
375    enabled will come into effect for that module.
376    
377    To enable the back-trace plugin, load library $/trace-debug-profile.cm
378    and invoke BackTrace.install() (e.g., from the interactive prompt).
379    To enable the coverage plugin, load the same library and invoke
380    Coverage.install().
381    
382    Back-traces are generated automatically on uncaught exceptions and
383    when the code in question explicitly invokes BackTrace.trigger().
384    
385    Coverage (and execution frequency-) information must be queried
386    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

401    Description:
402    
403    Some rationalization of names:
404    
405       structure BTrace -> structure TDPInstrument
406       etc.
407    
408    This is is preparation of using the original back-trace
409    instrumentation for other purposes.  "TDP" stands for
410    Trace/Debug/Profile.
411    
412    The control flag controlling whether instrumentation is on or off is now
413    registered under a different name, so instead of running sml as
414    
415     sml -Cinstrument.btrace-mode=true
416    
417    one has to say
418    
419     sml -Ctdp.instrument=true

434    Tag: blume-20041008-cmkw
435    Description:
436    
437    Fixed handling of keywords in .cm files: After seeing "is" the lexer
438    treats subsequent occurrences of "group", "library", "source", "is",
439    "*", and "-" as ordinary identifiers rather than keywords.
440    
441    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
442    is supposed to accept a tool argument called "source", but this did
443    not work because of the clash with the keyword.

475    Description:
476    
477    Added hack to make slave mode work in the presence of the version
478    tool.  (Still, since the master does two passes over the code for
479    CMB.make, the release number gets bumped twice when slaves are
480    attached.  I don't know if this is worth fixing...)

486    Description:
487    
488    * Moved the "version" magic into its own little library under
489      src/system/smlnj/internal.  This avoids expensive reconstruction of
490      a stable src/compiler/core.cm.
491    
492    * At the same time, structure CompilerVersion is now known as
493      structure SMLNJVersion.
494    
495    * Arranged for the version tool to NOT kick in when rebuilding the system
496      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
497      Also, loading the versiontool does not work when rebuilding the system
498      because CM is not properly initialized at that time.

504    Description:
505    
506    Implemented some CM magic to have
507        file src/compiler/TopLevel/main/version.sml
508    generated automagically.
509    The version is taken from two files: config/version and config/release.
510    The first is expected to contain a two-part version number such as 110.49.
511    The second should contain a single number, but it may be missing.
512    
513    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
514    time the version tool is loaded (which is the first time you say CMB.make),
515    then the tool will increment the value stored in config/release every
516    time CMB.make is invoked.
517    
518    The binfile format is now insensitive to anything beyond the first
519    two components of a version number, so bumping the release does not render
520    binfiles incompatible.  Auto-bumping can be used to keep track of versions
521    during development without invalidating existing binfiles.
522    
523    In any case, every CMB.make updates the date information in version.sml.
524    (This is the date that is printed in the banner.)

537    Tag: blume-20040927-controls
538    Description:
539    
540    Added two pieces of functionality to the Controls interface:
541    
542    1.   val save'restore: 'a control -> unit -> unit
543    
544       grabs the current value of the control in stage 1 and restores it
545       in stage 2.
546    
547    2.   val set' : 'a control * 'a -> unit -> unit
548    
549       stores the given value into the control in stage 2 (i.e., delayed)
550       but does all error checking in stage 1.
551       (This is for string controls that need to do parse their argument --
552        something that might fail.  In some cases, notably in CM, one
553        already knows the intended argument but wants to delay the actual
554        assignment until a time when error recovery would be more difficult.)
555    
556    Changed the handling of controls in tool arguments to classes "sml" and
557    "lazysml":
558       - use Controls.save'restore as a more robust way of restoring the
559         old value (in particular: without having to re-parse the string)
560       - use controls to handle the "overload" keyword in the init group
561         (I believe this change actually fixes a long-standing obscure bug.)

566    Tag: blume-20040927-lazysml
567    Description:
568    
569    Added a new tool class called "lazysml" to CM's tool chest.  The only
570    difference to "sml" is that compilation is done with Control.lazysml
571    set to true.  A source of class "lazysml" is automatically recognized
572    by a file name suffix of ".lml".
573    
574    In addition to the above feature, the original class "sml" now also
575    supports a tool argument "lazy" which has the same effect.  As a
576    result, the following three lines are equivalent:
577    
578        foo.sml : lazysml
579        foo.sml : sml (lazy)
580        foo.sml (lazy)
581    
582    The setting goes into effect both during parsing and during
583    compilation.  The original setting is restored right after parsing and
584    after compilation, respectively.
585    
586    In addition to all the above, there is also a general mechanism to set
587    ANY of the "controls" that are available at the command line via
588    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
589    apply as well. (In fact, "lazy" is implemented as a special case of
590    the general mechanism.)
591    
592    The .cm file syntax uses a new keyword tool argument called "with".
593    There are several ways of indicating the desired settings:
594    
595        foo.sml (with:parser.quotations=true)
596        foo.sml (with:(name:parser.quotations value:true))
597        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
598        foo.sml (with:(name1=value1 name2=value2 ...))
599        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
600    
601        etc.
602    
603    Another possible abbreviation is to leave out the =v or value:v part
604    if the name refers to a boolean control (in which case the value is
605    taken to be true).  Thus, one could get lazy sml also by saying:
606    
607        foo.sml (with:parser.lazy-keyword=true)
608        foo.sml (with:parser.lazy-keyword)
609        foo.sml (with:(name:parser.lazy-keyword value:true))
610        foo.sml (with:(name:parser.lazy-keyword))

926    Description:
927    
928    NLFFI under Mac OS X now working (sort of).  This is largely untested,
929    though.
930    
931    Note:  1. You have to make a new, clean build of the runtime system.
932           2. There are new BOOTFILES, you have to use them!
933              (Doing the bootstrap process yourself would be *very* painful!
934               If you absolutely have to do it, build the system under
935               a different architecture and then cross-compile.)
936    
937    Version bumped to 110.46.1 to account for runtime data format changes.

944    
945    Changed the implementation of structure Unix so that the same stream
946    is returned every time one of the {text,bin}{In,Out}streamOf functions
947    is invoked on the same proc.  This is not what the spec currently
948    says -- although IMO it arguably should.  (See discussion below.)

961    Tag: blume-20040617-timer-unix
962    Description:
963    
964    Changed the interface of structures Timer and Unix to match the most
965    recent Basis spec.
966    
967    In the case of Unix there still seems to be an open/weird issue:
968    
969       The {text,bin}{In,Out}streamOf functions are supposed to create
970       fresh streams whenever they are called -- as opposed to have them
971       return the same stream every time.  This design is supposed to
972       prevent space leaks caused by proc values hanging on to streams.
973    
974       The reap function, on the other hand, is supposed to close the
975       streams.  This cannot be done without having a handle on the
976       stream in proc after all...
977    
978    I took the liberty to implement the following stopgap solution:
979    
980      The proc value hangs on to the most recently created stream(s).
981      Reap closes those.  If either or both of the two streams hadn't
982      been created at all yet, then reap will close the corresponding
983      file descriptors directly.
984    
985    PS: I don't understand the original space leak argument anymore.  If
986    a proc hangs on to the imperative stream, then I/O operations on those
987    will advance the state of the cached stream and avoid the space leak.

1000    Tag: blume-20040525-group-owner
1001    Description:
1002    
1003    CM now ignores (but still accepts) the "owner" information in group
1004    descriptions.  The owner of a group is its next enclosing
1005    library. Each group must have a unique owner.  (There is a virtual
1006    "toplevel" library that owns groups which are not nested within a real
1007    library.)  Previously, each group had to explicitly declare its owner,
1008    and CM would check that such a declaration is correct.  The new scheme
1009    is to have CM check that for each group there is precisely one owning
1010    library.
1011    
1012    The advantage of the new scheme is that the programmer no longer needs
1013    to maintain the somewhat annoying owner information.  The downside is
1014    that CM cannot enforce the ownership rule across multiple runs of
1015    CM.make.  Fortunately, enclosing the same group in two different
1016    libraries A and B which are not part of the same program does not
1017    cause real problems.

1027    compiled correctly.)

1029    Also, included a minor addition to ml-build.bat analogous to what was
1030    done in blume-20040519-ml-build.

1036    Description:
1037    
1038    Arranged for ml-build to clean up after itself a little bit better.
1039    The script generates a temporary SML source file and compiles it using
1040    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
1041    gets rid of those at the end, so they don't accumulate under .cm.
1042    
1043    This required a minor change to install.sh because the name of the
1044    metadata directory (default: .cm) is actually configurable at
1045    installation time.

1060    Description:
1061    
1062    Added previously missing support for many socket-related functions
1063    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
1064    for the voluminous patch!
1065    
1066    (I have not tested this patch under win32 yet.)
1067    
1068    Here is David's e-mail:
1069    
1070    Hi,
1071    
1072    Attached to this email you find a diff against sml/nj 110.45
1073    that will enable socket support under Windows.
1074    
1075    To apply the patch (using unix or cygwin)
1076    1) gunzip runtime.diff.gz
1077    2) "cd" into "src/runtime" in the source tree of a fresh
1078       110.45 installation.
1079    3) patch -p 1 < [your/path/to]runtime.diff
1080    
1081    The code compiles fine but has NOT yet been extensively tested.
1082    I only ran a few tests for basic socket client functionality
1083    (which worked fine).  Especially the functions that use ioctl
1084    are not tested at all and might not work (see below).
1085    
1086    I implemented this since we want to move to a newer version of sml/nj
1087    but need socket support in order to use it.  This is the first time I
1088    even had a look at the sml/nj source,  so please review my changes
1089    before making this part of the distribution!  Here are a few issues
1090    that I think might be better for someone to solve who is more
1091    familiar with the sml/nj source (and socket programming):
1092    
1093    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1094      exception since I could not figure out what the windows equivalent
1095      of these functions is
1096    
1097    - In sockets-osdep.h there are a some #include statements that are
1098      only used in a few files that include sockets-osdep.h
1099    
1100    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1101      does not process its return value since I don't know how to
1102      report an error upwards.
1103    
1104    - It would probably be good to have a call to WSACleanup() when
1105      the library is unloaded (if there is such a possibility).
1106      Otherwise I think Windows will take care of this automatically
1107      when the process finishes.
1108    
1109    - I used ioctlsocket() as a replacement for ioctl() but I have
1110      no idea if that is actually the proper replacement on Windows.
1111    
1112    - All these issues are marked in the code by "FIXME" comments.
1113    
1114    We use sml/nj extensively in our products and are quite happy
1115    with it.  I hope this contribution will help you.
1116    
1117    Keep up the good work!
1118

1157    in the "targets" file, then the installer will pull in sources for
1158    everything.  (Notice that this refers to source code only.  Compiled
1159    code is still only installed for modules that were requested explicitly
1160    or which are required for other modules that were requested explicitly.)

1194    Description:

1196    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
1197    of SML/NJ.  The problem is that
1198    
1199       lib = dlopen(NULL, ...)
1200       f   = dlsym(lib, "malloc");
1201    
1202    does not work on Windows unless we explicitly export symbols
1203    such as 'malloc' during linking.  We fixed this by explicitly
1204    exporting the required symbols with the magic gcc incantation:
1205    
1206        -Wl,--export-all cygwin.def
1207    
1208    where cygwin.def is a file containing all the symbols that
1209    we wish to export.
1210    
1211    I suspect this is a Windows problem and we'll have to
1212    do the same (somehow with windows compilers) when
1213    we build the native win32 version with the system
1214    calls LoadLibrary/GetProcAddress.

1345    appears in CM's autoload registry.  As a result, we see far fewer of
1346    those ?.Foo.Bar.xxx names in the prettyprinter's output.
1347    
1348    In addition to this I tried to clean up some pieces of the Basis
1349    implementation (e.g., Socket, Word8Array) in order to prevent other
1350    instances of these ?.Foo.Bar.xxx names from being printed.
1351    
1352    The mechanism that picks names for types still needs some work, though.
1353    (Right now it seems that if there is a type A.t which is defined to
1354    be B.u, but B is unavailable at toplevel, then A.t gets printed as
1355    "?.B.u" although the perhaps more sensible solution would be to use
1356    "A.t" in this case.  In other words, the prettyprinter should follow
1357    a chain of DEFtycs not farther than there are corresponding toplevel
1358    names in the current environment.)

1364    Description:
1365    
1366    Another installer tweak:  All the ML code for the installer is now
1367    compiled during CMB.make and put into a little library called
1368    $smlnj/installer.cm.  The installation then simply invokes
1369    
1370       sml -m $smlnj/installer.cm
1371    
1372    and everything happens automagically.
1373    
1374    Win32:  ML code senses value of environment variable SMLNJ_HOME.
1375    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
1376            and BINDIR.
1377    
1378    The new scheme guarantees that the ML code responsible for the installation
1379    is in sync with the APIs of the main system.  Also, the installer is
1380    somewhat faster because the installer script is precompiled.

1387    
1388    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
1389    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
1390    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
1391    implementations of non-blocking operations from CML's Socket
1392    structure.

1398    Description:
1399    
1400    1. Fixed SOCKET API and implementation to match Basis spec.
1401       This required changing the internal representation of sockets to one
1402       that remembers (for each socket file descriptor) whether it is currently
1403       blocking or non-blocking.  This state is maintained lazily (i.e., a system
1404       call is made only if the state actually needs to change).
1405    
1406    2. OS-specific details of sockets were moved into separate files, thus
1407       making it possible to unify the bulk of the socket implementations
1408       between Unix and Win32.
1409    
1410    3. CML's socket API changed accordingly.
1411       (Note that we need to remove non-blocking functions from this API
1412       since they are redundant in the case of CML!)
1413    
1414    4. CML's socket implementation now makes use of non-blocking functions
1415       provided by Basis, thus removing all OS-dependent code from this part
1416       of CML.
1417    
1418    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

1437    1. new-install.sh -> install.sh
1438    2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
1439    3. tweaked installer so that another name instead of .cm can be chosen
1440       at install time (by setting the CM_DIR_ARC environment variable
1441       during installation); once installation is complete, the name is
1442       fixed

1461    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
1462       this seems to be controversial at the moment) and used those in
1463       Posix.ProcEnv.times.
1464    
1465    2. Added Time.{from,to}Nanoseconds to Time.
1466    
1467    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
1468       For example, fromLargeInt never needs to look at more than 3 "big
1469       digits" to get its 53 bits of precision.

1480    
1481    Removed some of the "magic" constants in real64.sml and replaced them
1482    with code that generates these values from their corresponding
1483    integer counterparts.
1484    
1485    Made all(?) the slice-related changes to the Basis and made everything
