43    Revision: 3648, 3652
44    Description:
45    
46    1) Change of SourceMap interface.
47       related to fix of off-by-one error in lexer (committed earlier?), and cleanup of noweb code
48       added by Norman Ramsey many years ago (but little used today).
49    
50    3) Slight cleanup of match compiler, eliminatiing compiler/FLINT/tempexpn.sml file that
51       was part of unused implementation of pattern templates (pattern macros).
52    
53    4) Modification of type checker to add "culprit tracking" for improved type error messages
54       (printing of additional culprit information is controlled by ElabControl.showTypeErrorCulprits
55        flag, default false, added in revision 3652).  The culprit tracking needs to be debugged
56        and improved, and the presentation of the culprits needs to be done better.
57    
58    Details in NOTES/changes/dbm_2012_1.

732    
733    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
734    
735    Also, changed the handling of "no core access":  When translate.sml
736    needs access to a core exception at a time when the core has not
737    been set up yet (this only happens when compiling system/smlnj/init/*),
738    then don't bother generating the corresponding tests.
739    
740    The old scheme was to generate a bogus value to be used in place of
741    the exception.  Unfortunately, that confuses the plambda type checker.
742    Moreover, it does not do any good, because at runtime we don't expect
743    such an exception to be ever raised.  (The code in system/smlnj/init/*
744    has to be written very carefully with this in mind!)

785    Description:
786    
787    CMB (and CM) now automatically defines the CM "preprocessor" symbol
788    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
789    
790      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
791       CM_SLAVE_MODE is defined in attached slaves while running CM.make
792       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
793       while running CMB.make.  The point is that the single symbol
794       NO_PLUGINS is definde in all three cases.)
795    
796    I changed the three locations within the sources that get compiled
797    during CMB.make where ml-yacc or ml-lex input is processed: When
798    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
799    is bypassed.
800    
801    When bootstrapping new versions of the compiler, there can be
802    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
803    are not available or otherwise not operational.  In this case one can
804    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
805    do so, the following command should be issued at the interactive
806    prompt:
807    
808       #set (CMB.symval "NO_PLUGINS") (SOME 1);
809    
810    A CMB.make with NO_PLUGINS defined relies on the existence of the
811    files that normally would be generated by ml-yacc and ml-lex.
812    (Copies of these files are in the repository.)

830    Changed the installation mechanism for CM tool plugins.  These are
831    just libaries and now get installed like ordinary libaries.
832    
833    There are now a number of new installation targets that give some
834    fine-grain control over what classes and suffixes are known, and what
835    they will map to.
836    See config/targets for details.
837    
838    The code that caused plugin installation as part of running a
839    tool's "build" script has been removed.  (The build script is for
840    building, not for installing.)

847    Added a boolean control named cm.tolerate-tool-failures (env. variable
848    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
849    CM fail if a shell tool reports a non-success exit status.  If
850    the control is set to true, then CM will press on after tool failures
851    in the event that the target files exist (even though they are
852    considered outdated).  Turning the control to true can be useful for
853    bootstrapping.

859    
860    Merge of ml-lpt revisions for 110.64.
861    
862    The name of several ml-lpt-lib modules has changed:
863      Repair        => AntlrRepair
864      StreamPos     => AntlrStreamPos
865      ErrHandlerFn  => AntlrErrHandler
866      EBNF          => AntlrEBNF
867    
868    The ml-antlr specification format has changed: declarations such as
869    %tokens and nonterminal definitions can occur *multiple* times in the
870    same specification.  The semantics are such that each new declaration
871    extends the previous ones.  This does not apply to %start or %name,
872    of course.
873    
874    Importing a grammar via %import now includes *all* declarations in from
875    the imported grammar, except for %name, %entry, and %start.  Tokens
876    and nonterminals can be dropped using the new %dropping clause of the
877    %import directive; the separate %drop and %extend have been removed.
878    
879    We now allow optional type annotations on nonterminals, using the %nonterms
880    directive as in ml-yacc.
881    
882    The refcell construct is now implemented using SML's regular reference
883    cells, so the :== and !! notation has been deprecated.
884    
885    The ml-antlr tool now does much more checking of specifications, and
886    its error messages have been greatly improved.  Error repair for
887    generated parsers has been completely rewritten, and is now both
888    much faster and more accurate.
889    
890    ml-ulex is now more lenient with escape codes (non-SML-standard
891    escape codes are now interpreted literally, so e.g. \| denotes "|").
892    Also, character classes may now include a "-" character at the beginning
893    as is standard in most other regexp tools.
894    
895    All of these changes are documented in the user guide, which has
896    been updated and improved with this merge.

917    same specification.  The semantics are such that each new declaration
918    extends the previous ones.  Grammar extension constructs have also

924    The ml-antlr tool now does much more checking of specifications, and
925    its error messages have been greatly improved.  There has also been
926    some work on the error repair process for generated parsers, but this
927    will be further improved in 110.64.

978    allocation.

1016    Description:
1017    
1018    Added preliminary support in MLRISC for Staged Allocation, a technique
1019    for specifying calling conventions (see
1020    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
1021    Initially, we plan to use this code to generate C calls for the AMD64.
1022    
1023    The staged allocation code base resides in MLRISC/staged-allocation,
1024    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1105    Implemented library installer.  Moved CM plugin code for
1106    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1107    their respective trees.  Implemented CM plugin for ml-ulex
1108    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
1109    and ml-antlr.
1110    
1111    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1112    CM tools.  (It turns out to be too messy to do otherwise because
1113    there is too much code that during installation relies on the presence
1114    of these tools -- resulting in a tricky ordering problem.)

1121    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1122    Modified CM's startup code to use shiftArgs as it processes
1123    command line arguments.  This way, the init code in each .sml-file
1124    or library that is mentioned at the top level will see only
1125    those arguments that have not yet been processed at this point.
1126    In other words, the init code can "seize control" and process the
1127    remaining command line.

1194    Description:
1195    
1196    Added code to CM's "standard shell tool" implementation which
1197    causes it to tolerate (with a warning) the situation where the shell
1198    command fails (e.g., due to the shell command's non-existence)
1199    as long as all target files exist.
1200    
1201    This makes it possible to, e.g., build ml-yacc from sources even if
1202    svn checkout messed up the time stamps on files in such a way that
1203    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
1204    be needed to re-process yacc.grm, but obviously it might not yet be
1205    available at that time.)

1246    
1247    New working release (110.60).  NEW BOOTFILES!
1248    
1249    This is the first subversion-hosted release.  There are also changes
1250    to the directory layout.  Here is a table:
1251    
1252    (All pathnames are relative to the SML/NJ "root" directory.)
1253    
1254      config -> config
1255    
1256      src/cm -> base/cm
1257      src/compiler -> base/compiler
1258      src/runtime -> base/runtime
1259      src/system -> base/system
1260    
1261      src/cm/pgraph -> pgraph
1262    
1263      src/READMES -> base/READMES
1264      src/$notefile -> base/NOTES/$notefile
1265         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1266                           MACOSXINSTALL WININSTALL
1267    
1268      src/smlnj-lib -> smlnj-lib
1269      src/MLRISC -> MLRISC
1270      ckit -> ckit
1271      src/cml -> cml
1272      src/eXene -> eXene
1273      src/heap2asm -> heap2asm
1274      src/lexgen -> lexgen
1275      src/ml-burg -> ml-burg
1276      src/ml-lex -> ml-lex
1277      src/ml-yacc -> ml-yacc
1278      src/ml-nlffi-lib -> nlffi/lib
1279      src/ml-nlffigen -> nlffi/gen
1280      src/smlnj-c -> smlnj-c
1281      src/tools/TraceDebugProf -> trace-debug-profile
1282    
1283    In addition, there is also a new
1284    
1285      ml-lpt
1286    
1287    directory containing two new program generator tools: ml-ulex and
1288    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1289    LL(k) parser generator). These tools are currently "beta-quality"
1290    
1291    The latest versios of the sources can now be obtained anonymously
1292    via subversion.  For this, it is useful to first check out
1293    
1294       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1295    
1296    and put the resulting directory on your shell's PATH.  This provides
1297    access to three shell scripts: checkout-all.sh, stat-all.sh,
1298    and refresh-all.sh.
1299    
1300    To create a freshly checked-out copy of the sources, do
1301    
1302       checkout-all.sh [dir]
1303    
1304    where dir is the optional SML/NJ root directory (default is ".").
1305    
1306    This creates the above directory layout.  Each subdirectory of
1307    the root is under individual subversion control.  The stat-all.sh
1308    and refresh-al.sh scripts apply "svn stat" or "svn update" to
1309    each of these subtrees.
1310

1313    Date: 2006/11/02 12:20:00 CST
1314    Description:
1315    
1316    Reorganized directory layout.
1317    
1318    This is a temporary solution, more reorganization is to come.
1319    
1320    The basic idea is to have a number of toplevel trees, each corresponding
1321    to a well-defined part of the overall system.  Each part can be
1322    maintained individually, even in separate source repositories,
1323    although currently we still serve everything out of the main
1324    smlnj-gforge tree.
1325    
1326    Installer and and scripts have been updated to reflect the new
1327    layout.  The installer (base/src/system/smlnj/installer) is now
1328    "scriptable" to avoid burning too much knowledge about the
1329    layout into SML source code.  The main script used by the installer
1330    is in config/actions.
1331    
1332    The main change is that many of the subdirectories of what used to
1333    be known as "src" have moved to the toplevel.  The "src" directory
1334    itself has moved down into a subtree called "base".  (We may eventually
1335    get rid of the extra level of indirection represented by "src".)
1336    
1337    The layout is now as follows:
1338    
1339      toplevel tree name | default repository
1340                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1341      -------------------+----------------------------------------------------
1342      config             | $gf/config/trunk
1343                         |
1344      base               | $gf/sml/trunk
1345                         |
1346      smlnj-lib          | $gf/smlnj-lib/trunk
1347      MLRISC             | $gf/MLRISC/trunk
1348                         |
1349      ml-yacc            | $gf/ml-yacc/trunk
1350      ml-lex             | $gf/ml-lex/trunk
1351      ml-burg            | $gf/ml-burg/trunk
1352      lexgen             | $gf/lexgen/trunk
1353      heap2asm           | $gf/heap2asm/trunk
1354                         |
1355      cml                | $gf/cml/trunk
1356      eXene              | $gf/eXene/trunk
1357      ckit               | $gf/ckit/trunk
1358      nlffi              | $gf/nlffi/trunk
1359                         |
1360      smlnj-c            | $gf/smlnj-c/trunk
1361    
1362    In $gf/admin there are a few useful shell scripts for checking out
1363    and maintaining the entire collection of trees:
1364    
1365       admin/checkout-all.sh [dir]
1366          -- optionally creates dir and checks out all trees from their
1367             default repositories; if dir is missing, checkout into .
1368       admin/refresh-all.sh [dir]
1369          -- looks at all trees (from the above list) in dir (default: .)
1370             and runs "svn update" if the tree exists and is under
1371             subversion control;
1372             non-existing or non-subversion trees are skipped
1373       admin/stat-all.sh [dir]
1374          -- like refresh-all.sh, but runs "svn stat" instead

1418    Description:
1419    
1420    Implemented ml-makedepend (i.e., CM.sources) in a better (more robust)
1421    way.  This should hopefully fix the ml-makedepend problem permanently.

1427    Description:
1428    
1429    Fixed long-standing bug with ml-makedepend where it would output a
1430    spurious dependency to a non-existing file.  (This is a simple fix.
1431    It might need further looking into.)

1523    (This is a temporary solution which relies on the fact that the

1525    intel mac from generic x86 unix code and make separate sets of binaries.)

1554    Description:
1555    
1556    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1557    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1558    at the time when config/preloads is processed, the library has to
1559    be referred to by another name.  In 110.57 this would be
1560    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1561    to be valid as well.)
1562    
1563    Thanks to Todd Wilson (Fresno) for alerting me to this issue.

1616    Tag: blume-22051115-versiontool
1617    Description:
1618    
1619    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1620    file gets loaded as a tool -- by the equivalent of CM.make during the
1621    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1622    it.  Instead, it has the status of "user code", so it should use
1623    $/basis.cm to refer to the Basis library.  (At least that's true for
1624    the purpose of bootstrapping the previous change.  In the future it
1625    might make sense to have versiontool.cm refer to
1626    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1627    compiler itself uses.)
1628    
1629    Also patched src/system/testml to have it activate those extra anchor
1630    bindings in config/extrapathconfig.

1635    Tag: blume-22051115-libraries
1636    Description:
1637    
1638    This change affects the way the following libraries are tied into
1639    the system:
1640    
1641       $/basis.cm
1642       $/smlnj-lib.cm
1643       $/pp-lib.cm
1644       $/controls-lib.cm
1645       $/html-lib.cm
1646       $/ml-yacc-lib.cm
1647    
1648    These libraries are now internally (as seen from the source code
1649    of the implementation itself) known by the following names:
1650    
1651       $smlnj/basis/basis.cm
1652       $smlnj/smlnj-lib/smlnj-lib.cm
1653       $smlnj/smlnj-lib/pp-lib.cm
1654       $smlnj/smlnj-lib/controls-lib.cm
1655       $smlnj/smlnj-lib/html-lib.cm
1656       $smlnj/ml-yacc/ml-yacc-lib.cm
1657    
1658    This makes it possible to work with code that requires different
1659    versions of these libraries, and which refers to these libraries using
1660    their "default" names (i.e., the first set of names above).  In other
1661    words, one can un-define or re-define those default names without
1662    compromising the proper functioning of the compiler itself.
1663    
1664    A similar procedure had already been performed for several of the
1665    MLRISC libraries that are linked into the compiler.  I did some
1666    cleanup on this code.
1667    
1668    A new file in the config directory (named extrapathconfig) is
1669    responsible for setting up path anchors that the compiler itself does
1670    not need, but that are typically required by user code.

1855       CM.redump_heap : string -> unit
1856    
1857    This is much like SMLofNJ.exportML, but starting from the resulting
1858    heap does not return to the caller of CM.redump_heap but
1859    restarts the interactive system from scratch.  The original call of
1860    CM.redump_heap does not return but ends the interactive session.
1861    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1862    
1863    Internally, redump_heap winds the dynamic execution context back to
1864    the point where the original heap image was created and re-executes
1865    the heap image generation code in the boot code.

1982    Description:
1983    
1984    Implemented new (but still experimental) heap2exec facility.  This is
1985    tested under Mac OS X and should work under Linux (will test shortly).
1986    It will probably also work on the Sparc (will test some time later).
1987    
1988      - removed old "HACKED_STANDALONE" hack from runtime
1989    
1990    To be able to test this, uncomment the request for "heap2asm" in
1991    config/targets prior to installation.  (Notice that this is different
1992    from "heap2exec" mentioned below.  Not a typo.)
1993    
1994    To perform an actual test, run the command
1995    
1996       $ bin/heap2exec heapfile execfile
1997    
1998    (You can put heap2exec on your shell's path.)
1999    
2000    For example, run
2001    
2002      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2003    
2004    This will create a standalone executable called "mly" which you can
2005    then invoke directly as a command.

2150    Tag: blume-20041124-position
2151    Description:
2152    
2153    The compiler can now be compiled in a mode that makes structure Position
2154    equal to Int64.  The default, however, is unchanged (Position = Int31)
2155    for the time being.
2156    
2157    To enable 64-bit positions, use the following procedure:
2158    
2159    1. Start sml
2160    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2161    3. Type
2162          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2163    4. Run CMB.make() as usual.
2164    
2165    This is barely tested.  The only test so far was a little SML program
2166    counting the number of characters in an 8-gigabyte file by
2167    reading it character-by-character.  That test was successful.
2168    
2169    In support of 64-bit positions, a number of new functions have been
2170    added to the runtime system.

2215    
2216    - In a previous commit, fixed a minor issue with how polyequal is being
2217      translated.  In particular, the code now "looks through" abstractions.
2218      This results in slightly fewer polyEqual warnings and hopefully slightly
2219      more efficient code.  Important examples for where this matters are
2220      the new int64 and word64 types.

2237    All the pieces of Word64 are now there, with the exception of the

2239    but for the time being they don't even make sense because LargeWord is
2240    32-bit wide.)
2241    
2242    Also started to add similar support for Int64, but major pieces of that
2243    are still missing.

2249    Description:
2250    
2251    Structure Word64 is now (almost) complete, word literals and patterns
2252    seem to work.  There are a few odd pieces missing.  In particular,
2253    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2254    at the moment.
2255    
2256    Making Word64 official would mean that LargeWord becomes Word64.  But
2257    this requires extreme care because most word-word conversions have to
2258    go through LargeWord, so making a mistake means loss of efficiency or
2259    worse.  Eventually there will be a solution similar to (but actually
2260    simpler than) what I did with IntInf.

2289    
2290    Also:
2291    
2292      - Changend config/srcarchiveurl from a file just
2293        containing the URL string into a file containing
2294        shell script code.  The code has access to the $VERSION variable.
2295      - Made corresponding changes to config/install.sh and config/unpack.
2296      - Default contents of config/srcarchiveurl uses $VERSION and
2297        normally does not have to be edited to reflect a version change.
2298    
2299      (As a result, a version change can be done by just editing
2300       config/version, the rest is now automatic.)

2321      - made sure the caller does not add the wrong number of bytes to the
2322        stack pointer after a call of a function returning a struct
2323        (the callee already pops the implicit argument which points to

2340    Tag: blume-20041020-standalone-backtrace
2341    Description:
2342    
2343    Added a mechanism for getting back-trace information from standalone
2344    programs.  Here is how it works:
2345    
2346       1. The part of the program from which you want to get backtrace
2347          information (usually the whole program) should be wrapped with
2348          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
2349          main program could be modified from something like
2350    
2351             fun main (pgm, args) = ...
2352    
2353         to
2354    
2355            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2356    
2357       2. To be able to access BackTrace.monitor, you have to add
2358          library $smlnj-tdp/plugins.cm to the .cm file that contains your
2359          main function.
2360    
2361       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2362          CM might have created in the past for your project).
2363    
2364       4. Build the system using this command line:
2365    
2366             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2367                      myprog.cm MyProg.main myprog
2368    
2369          instead of the usual
2370    
2371             ml-build myprog.cm MyProg.main myprog
2372    
2373    I changed a library name:
2374    
2375       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2376    
2377    New libraries:
2378    
2379       $smlnj-tdp/back-trace.cm
2380          -- when loaded causes the back-trace plugin to be installed
2381       $smlnj-tdp/coverage.cm
2382          -- when loaded causes the coverage plugin to be installed

2398    Description:
2399    
2400    * Test coverage tool added!
2401    * Further reorganization of tracing-, debugging-, and profiling support:
2402    
2403        - moved original BTImp -- now called BackTrace -- into a separate
2404          library called $/trace-debug-profile.cm
2405        - eliminated all mentions of BTrace from SMLofNJ.Internals
2406        - only the instrumentation mechanism is now left in the compiler proper
2407        - BackTrace module is a plugin which is NOT plugged in by default
2408        - Coverage module is another such plugin
2409    
2410    To get the benefits of any of these plugin modules, the code in
2411    question must be compiled with tdp instrumentation turned on.  This
2412    can be done by setting SMLofNJ.Internals.TDP.mode to true.
2413    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2414    
2415    Plugins are selected at link time.  (Pre-compiled instrumented code
2416    can be re-loaded with different plugins in effect.)  When an
2417    instrumented module is linked, whatever plugins are at that time
2418    enabled will come into effect for that module.
2419    
2420    To enable the back-trace plugin, load library $/trace-debug-profile.cm
2421    and invoke BackTrace.install() (e.g., from the interactive prompt).
2422    To enable the coverage plugin, load the same library and invoke
2423    Coverage.install().
2424    
2425    Back-traces are generated automatically on uncaught exceptions and
2426    when the code in question explicitly invokes BackTrace.trigger().
2427    
2428    Coverage (and execution frequency-) information must be queried
2429    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2446    Some rationalization of names:

2450    
2451    This is is preparation of using the original back-trace
2452    instrumentation for other purposes.  "TDP" stands for
2453    Trace/Debug/Profile.
2454    
2455    The control flag controlling whether instrumentation is on or off is now
2456    registered under a different name, so instead of running sml as
2457    
2458     sml -Cinstrument.btrace-mode=true
2459    
2460    one has to say
2461    
2462     sml -Ctdp.instrument=true

2478    Description:
2479    
2480    Fixed handling of keywords in .cm files: After seeing "is" the lexer
2481    treats subsequent occurrences of "group", "library", "source", "is",
2482    "*", and "-" as ordinary identifiers rather than keywords.
2483    
2484    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2485    is supposed to accept a tool argument called "source", but this did
2486    not work because of the clash with the keyword.

2530    
2531    * Moved the "version" magic into its own little library under
2532      src/system/smlnj/internal.  This avoids expensive reconstruction of
2533      a stable src/compiler/core.cm.
2534    
2535    * At the same time, structure CompilerVersion is now known as
2536      structure SMLNJVersion.
2537    
2538    * Arranged for the version tool to NOT kick in when rebuilding the system
2539      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2540      Also, loading the versiontool does not work when rebuilding the system
2541      because CM is not properly initialized at that time.

2546    Tag: blume-20040929-autoversion
2547    Description:
2548    
2549    Implemented some CM magic to have
2550        file src/compiler/TopLevel/main/version.sml
2551    generated automagically.
2552    The version is taken from two files: config/version and config/release.
2553    The first is expected to contain a two-part version number such as 110.49.
2554    The second should contain a single number, but it may be missing.
2555    
2556    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2557    time the version tool is loaded (which is the first time you say CMB.make),
2558    then the tool will increment the value stored in config/release every
2559    time CMB.make is invoked.
2560    
2561    The binfile format is now insensitive to anything beyond the first
2562    two components of a version number, so bumping the release does not render
2563    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2564    during development without invalidating existing binfiles.
2565    
2566    In any case, every CMB.make updates the date information in version.sml.
2567    (This is the date that is printed in the banner.)

2580    Tag: blume-20040927-controls
2581    Description:
2582    
2583    Added two pieces of functionality to the Controls interface:
2584    
2585    1.   val save'restore: 'a control -> unit -> unit
2586    
2587       grabs the current value of the control in stage 1 and restores it
2588       in stage 2.
2589    
2590    2.   val set' : 'a control * 'a -> unit -> unit
2591    
2592       stores the given value into the control in stage 2 (i.e., delayed)
2593       but does all error checking in stage 1.
2594       (This is for string controls that need to do parse their argument --
2595        something that might fail.  In some cases, notably in CM, one
2596        already knows the intended argument but wants to delay the actual
2597        assignment until a time when error recovery would be more difficult.)
2598    
2599    Changed the handling of controls in tool arguments to classes "sml" and
2600    "lazysml":
2601       - use Controls.save'restore as a more robust way of restoring the
2602         old value (in particular: without having to re-parse the string)
2603       - use controls to handle the "overload" keyword in the init group
2604         (I believe this change actually fixes a long-standing obscure bug.)

2609    Tag: blume-20040927-lazysml
2610    Description:
2611    
2612    Added a new tool class called "lazysml" to CM's tool chest.  The only
2613    difference to "sml" is that compilation is done with Control.lazysml
2614    set to true.  A source of class "lazysml" is automatically recognized
2615    by a file name suffix of ".lml".
2616    
2617    In addition to the above feature, the original class "sml" now also
2618    supports a tool argument "lazy" which has the same effect.  As a
2619    result, the following three lines are equivalent:
2620    
2621        foo.sml : lazysml
2622        foo.sml : sml (lazy)
2623        foo.sml (lazy)
2624    
2625    The setting goes into effect both during parsing and during
2626    compilation.  The original setting is restored right after parsing and
2627    after compilation, respectively.
2628    
2629    In addition to all the above, there is also a general mechanism to set
2630    ANY of the "controls" that are available at the command line via
2631    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2632    apply as well. (In fact, "lazy" is implemented as a special case of
2633    the general mechanism.)
2634    
2635    The .cm file syntax uses a new keyword tool argument called "with".
2636    There are several ways of indicating the desired settings:
2637    
2638        foo.sml (with:parser.quotations=true)
2639        foo.sml (with:(name:parser.quotations value:true))
2640        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2641        foo.sml (with:(name1=value1 name2=value2 ...))
2642        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2643    
2644        etc.
2645    
2646    Another possible abbreviation is to leave out the =v or value:v part
2647    if the name refers to a boolean control (in which case the value is
2648    taken to be true).  Thus, one could get lazy sml also by saying:
2649    
2650        foo.sml (with:parser.lazy-keyword=true)
2651        foo.sml (with:parser.lazy-keyword)
2652        foo.sml (with:(name:parser.lazy-keyword value:true))
2653        foo.sml (with:(name:parser.lazy-keyword))

3005    Description:
3006    
3007    Changed the interface of structures Timer and Unix to match the most
3008    recent Basis spec.
3009    
3010    In the case of Unix there still seems to be an open/weird issue:
3011    
3012       The {text,bin}{In,Out}streamOf functions are supposed to create
3013       fresh streams whenever they are called -- as opposed to have them
3014       return the same stream every time.  This design is supposed to
3015       prevent space leaks caused by proc values hanging on to streams.
3016    
3017       The reap function, on the other hand, is supposed to close the
3018       streams.  This cannot be done without having a handle on the
3019       stream in proc after all...
3020    
3021    I took the liberty to implement the following stopgap solution:
3022    
3023      The proc value hangs on to the most recently created stream(s).
3024      Reap closes those.  If either or both of the two streams hadn't
3025      been created at all yet, then reap will close the corresponding
3026      file descriptors directly.
3027    
3028    PS: I don't understand the original space leak argument anymore.  If
3029    a proc hangs on to the imperative stream, then I/O operations on those
3030    will advance the state of the cached stream and avoid the space leak.

3044    Description:
3045    
3046    CM now ignores (but still accepts) the "owner" information in group
3047    descriptions.  The owner of a group is its next enclosing
3048    library. Each group must have a unique owner.  (There is a virtual
3049    "toplevel" library that owns groups which are not nested within a real
3050    library.)  Previously, each group had to explicitly declare its owner,
3051    and CM would check that such a declaration is correct.  The new scheme
3052    is to have CM check that for each group there is precisely one owning
3053    library.
3054    
3055    The advantage of the new scheme is that the programmer no longer needs
3056    to maintain the somewhat annoying owner information.  The downside is
3057    that CM cannot enforce the ownership rule across multiple runs of
3058    CM.make.  Fortunately, enclosing the same group in two different
3059    libraries A and B which are not part of the same program does not
3060    cause real problems.

3080    
3081    Arranged for ml-build to clean up after itself a little bit better.
3082    The script generates a temporary SML source file and compiles it using
3083    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
3084    gets rid of those at the end, so they don't accumulate under .cm.
3085    
3086    This required a minor change to install.sh because the name of the
3087    metadata directory (default: .cm) is actually configurable at
3088    installation time.

3103    Description:
3104    
3105    Added previously missing support for many socket-related functions
3106    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
3107    for the voluminous patch!
3108    
3109    (I have not tested this patch under win32 yet.)
3110    
3111    Here is David's e-mail:
3112    
3113    Hi,
3114    
3115    Attached to this email you find a diff against sml/nj 110.45
3116    that will enable socket support under Windows.
3117    
3118    To apply the patch (using unix or cygwin)
3119    1) gunzip runtime.diff.gz
3120    2) "cd" into "src/runtime" in the source tree of a fresh
3121       110.45 installation.
3122    3) patch -p 1 < [your/path/to]runtime.diff
3123    
3124    The code compiles fine but has NOT yet been extensively tested.
3125    I only ran a few tests for basic socket client functionality
3126    (which worked fine).  Especially the functions that use ioctl
3127    are not tested at all and might not work (see below).
3128    
3129    I implemented this since we want to move to a newer version of sml/nj
3130    but need socket support in order to use it.  This is the first time I
3131    even had a look at the sml/nj source,  so please review my changes
3132    before making this part of the distribution!  Here are a few issues
3133    that I think might be better for someone to solve who is more
3134    familiar with the sml/nj source (and socket programming):
3135    
3136    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3137      exception since I could not figure out what the windows equivalent
3138      of these functions is
3139    
3140    - In sockets-osdep.h there are a some #include statements that are
3141      only used in a few files that include sockets-osdep.h

3143    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3144      does not process its return value since I don't know how to
3145      report an error upwards.
3146    
3147    - It would probably be good to have a call to WSACleanup() when
3148      the library is unloaded (if there is such a possibility).
3149      Otherwise I think Windows will take care of this automatically
3150      when the process finishes.
3151    
3152    - I used ioctlsocket() as a replacement for ioctl() but I have
3153      no idea if that is actually the proper replacement on Windows.
3154    
3155    - All these issues are marked in the code by "FIXME" comments.
3156    
3157    We use sml/nj extensively in our products and are quite happy
3158    with it.  I hope this contribution will help you.
3159    
3160    Keep up the good work!

3197    The installer now honors the "src-smlnj" target again, although its meaning
3198    has changed from "all sources required for the compiler" to "all sources
3199    the installer knows about".  In other words, if you enable "src-smlnj"
3200    in the "targets" file, then the installer will pull in sources for
3201    everything.  (Notice that this refers to source code only.  Compiled
3202    code is still only installed for modules that were requested explicitly
3203    or which are required for other modules that were requested explicitly.)

3237    Description:
3238    
3239    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
3240    of SML/NJ.  The problem is that
3241    
3242       lib = dlopen(NULL, ...)
3243       f   = dlsym(lib, "malloc");
3244    
3245    does not work on Windows unless we explicitly export symbols
3246    such as 'malloc' during linking.  We fixed this by explicitly
3247    exporting the required symbols with the magic gcc incantation:
3248    
3249        -Wl,--export-all cygwin.def
3250    
3251    where cygwin.def is a file containing all the symbols that
3252    we wish to export.
3253    
3254    I suspect this is a Windows problem and we'll have to
3255    do the same (somehow with windows compilers) when
3256    we build the native win32 version with the system
3257    calls LoadLibrary/GetProcAddress.

3330    lib during installation.  I originally implemented this directive as a
3331    backward-compatibility feature when I first introduced the new CM.
3332    Now that things have been stable for a long time and going back to the
3333    old CM is not an option, there is no reason to keep it around.)

3383    Description:
3384    
3385    I modified the read-eval-print loop so that the autoloader gets
3386    invoked whenever the prettyprinter tries to look up a symbol that
3387    is not currently defined in the toplevel environment but which
3388    appears in CM's autoload registry.  As a result, we see far fewer of
3389    those ?.Foo.Bar.xxx names in the prettyprinter's output.
3390    
3391    In addition to this I tried to clean up some pieces of the Basis
3392    implementation (e.g., Socket, Word8Array) in order to prevent other
3393    instances of these ?.Foo.Bar.xxx names from being printed.
3394    
3395    The mechanism that picks names for types still needs some work, though.
3396    (Right now it seems that if there is a type A.t which is defined to
3397    be B.u, but B is unavailable at toplevel, then A.t gets printed as
3398    "?.B.u" although the perhaps more sensible solution would be to use
3399    "A.t" in this case.  In other words, the prettyprinter should follow
3400    a chain of DEFtycs not farther than there are corresponding toplevel
3401    names in the current environment.)

3407    Description:
3408    
3409    Another installer tweak:  All the ML code for the installer is now
3410    compiled during CMB.make and put into a little library called
3411    $smlnj/installer.cm.  The installation then simply invokes
3412    
3413       sml -m $smlnj/installer.cm
3414    
3415    and everything happens automagically.
3416    
3417    Win32:  ML code senses value of environment variable SMLNJ_HOME.
3418    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
3419            and BINDIR.
3420    
3421    The new scheme guarantees that the ML code responsible for the installation
3422    is in sync with the APIs of the main system.  Also, the installer is
3423    somewhat faster because the installer script is precompiled.

3435    structure.

3440    Tag: blume-20030924-sockets
3441    Description:
3442    
3443    1. Fixed SOCKET API and implementation to match Basis spec.
3444       This required changing the internal representation of sockets to one
3445       that remembers (for each socket file descriptor) whether it is currently
3446       blocking or non-blocking.  This state is maintained lazily (i.e., a system
3447       call is made only if the state actually needs to change).
3448    
3449    2. OS-specific details of sockets were moved into separate files, thus
3450       making it possible to unify the bulk of the socket implementations
3451       between Unix and Win32.
3452    
3453    3. CML's socket API changed accordingly.
3454       (Note that we need to remove non-blocking functions from this API
3455       since they are redundant in the case of CML!)
3456    
3457    4. CML's socket implementation now makes use of non-blocking functions
3458       provided by Basis, thus removing all OS-dependent code from this part
3459       of CML.
3460    
3461    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.
