40    Description:
41    Fix bug #111 (Socket.acceptNB returns somewhat broken sockets).
42    The problem was that under Win32, sockets returned from accept inherit
43    their parents' non-blocking status, whereas on UNIX they are always
44    blocking.

58    Fix bug #116 (Socket.sameDesc raises Match exception).
59    The problem is that on Windows the iodesc datatype (defined in
60    Basis/Implementation/Win32/pre-os.sml) has both an IODesc constructor
61    and a SockDesc constructor.  Updated the code in Win32/os-io.sml to
62    handle the SockDesc constructor.

183    Revision: 3648, 3652
184    Description:
185    
186    1) Change of SourceMap interface.
187       related to fix of off-by-one error in lexer (committed earlier?), and cleanup of noweb code
188       added by Norman Ramsey many years ago (but little used today).
189    
190    3) Slight cleanup of match compiler, eliminatiing compiler/FLINT/tempexpn.sml file that
191       was part of unused implementation of pattern templates (pattern macros).
192    
193    4) Modification of type checker to add "culprit tracking" for improved type error messages
194       (printing of additional culprit information is controlled by ElabControl.showTypeErrorCulprits
195        flag, default false, added in revision 3652).  The culprit tracking needs to be debugged
196        and improved, and the presentation of the culprits needs to be done better.
197    
198    Details in NOTES/changes/dbm_2012_1.

872    
873    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
874    
875    Also, changed the handling of "no core access":  When translate.sml
876    needs access to a core exception at a time when the core has not
877    been set up yet (this only happens when compiling system/smlnj/init/*),
878    then don't bother generating the corresponding tests.
879    
880    The old scheme was to generate a bogus value to be used in place of
881    the exception.  Unfortunately, that confuses the plambda type checker.
882    Moreover, it does not do any good, because at runtime we don't expect
883    such an exception to be ever raised.  (The code in system/smlnj/init/*
884    has to be written very carefully with this in mind!)

925    Description:
926    
927    CMB (and CM) now automatically defines the CM "preprocessor" symbol
928    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
929    
930      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
931       CM_SLAVE_MODE is defined in attached slaves while running CM.make
932       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
933       while running CMB.make.  The point is that the single symbol
934       NO_PLUGINS is definde in all three cases.)
935    
936    I changed the three locations within the sources that get compiled
937    during CMB.make where ml-yacc or ml-lex input is processed: When
938    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
939    is bypassed.
940    
941    When bootstrapping new versions of the compiler, there can be
942    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
943    are not available or otherwise not operational.  In this case one can
944    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
945    do so, the following command should be issued at the interactive
946    prompt:
947    
948       #set (CMB.symval "NO_PLUGINS") (SOME 1);
949    
950    A CMB.make with NO_PLUGINS defined relies on the existence of the
951    files that normally would be generated by ml-yacc and ml-lex.
952    (Copies of these files are in the repository.)

970    Changed the installation mechanism for CM tool plugins.  These are

975    they will map to.
976    See config/targets for details.
977    
978    The code that caused plugin installation as part of running a
979    tool's "build" script has been removed.  (The build script is for
980    building, not for installing.)

985    Description:
986    
987    Added a boolean control named cm.tolerate-tool-failures (env. variable
988    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
989    CM fail if a shell tool reports a non-success exit status.  If
990    the control is set to true, then CM will press on after tool failures
991    in the event that the target files exist (even though they are
992    considered outdated).  Turning the control to true can be useful for
993    bootstrapping.

998    Description:
999    
1000    Merge of ml-lpt revisions for 110.64.
1001    
1002    The name of several ml-lpt-lib modules has changed:
1003      Repair        => AntlrRepair
1004      StreamPos     => AntlrStreamPos
1005      ErrHandlerFn  => AntlrErrHandler
1006      EBNF          => AntlrEBNF
1007    
1008    The ml-antlr specification format has changed: declarations such as
1009    %tokens and nonterminal definitions can occur *multiple* times in the
1010    same specification.  The semantics are such that each new declaration
1011    extends the previous ones.  This does not apply to %start or %name,
1012    of course.
1013    
1014    Importing a grammar via %import now includes *all* declarations in from
1015    the imported grammar, except for %name, %entry, and %start.  Tokens
1016    and nonterminals can be dropped using the new %dropping clause of the
1017    %import directive; the separate %drop and %extend have been removed.
1018    
1019    We now allow optional type annotations on nonterminals, using the %nonterms
1020    directive as in ml-yacc.
1021    
1022    The refcell construct is now implemented using SML's regular reference
1023    cells, so the :== and !! notation has been deprecated.
1024    
1025    The ml-antlr tool now does much more checking of specifications, and
1026    its error messages have been greatly improved.  Error repair for
1027    generated parsers has been completely rewritten, and is now both
1028    much faster and more accurate.
1029    
1030    ml-ulex is now more lenient with escape codes (non-SML-standard
1031    escape codes are now interpreted literally, so e.g. \| denotes "|").
1032    Also, character classes may now include a "-" character at the beginning
1033    as is standard in most other regexp tools.
1034    
1035    All of these changes are documented in the user guide, which has
1036    been updated and improved with this merge.

1043    
1044    Merge of the primop3 branch (base) into the trunk to create 110.63.1.
1045    Significant changes in FLINT and the front end, mostly having to do
1046    with a reorganized system for handling primops.  Various bug fixes
1047    and improvements in printing signatures.

1052    Description:
1053    
1054    Preliminary commit of large ml-lpt revisions (more to come for 110.64).
1055    The ml-antlr specification format has changed: declarations such as
1056    %tokens and nonterminal definitions can occur *multiple* times in the
1057    same specification.  The semantics are such that each new declaration
1058    extends the previous ones.  Grammar extension constructs have also
1059    changed.  We now allow type annotations on nonterminals.  Finally,
1060    the refcell construct is now implemented using SML's regular reference
1061    cells, so the :== and !! notation has been deprecated.  All of these
1062    changes will appear in the 110.64 user guide for ml-lpt.
1063    
1064    The ml-antlr tool now does much more checking of specifications, and
1065    its error messages have been greatly improved.  There has also been
1066    some work on the error repair process for generated parsers, but this
1067    will be further improved in 110.64.

1157    
1158    Added preliminary support in MLRISC for Staged Allocation, a technique
1159    for specifying calling conventions (see
1160    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
1161    Initially, we plan to use this code to generate C calls for the AMD64.
1162    
1163    The staged allocation code base resides in MLRISC/staged-allocation,
1164    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1230    
1231    Brought ml-lpt manual up-to-date with the code.  Many minor
1232    improvements to the tools, and a few minor bugfixes.  Prepared
1233    ml-lpt-lib for integration with new UTF8 structure.  Changed
1234    the interface for creating streams in ml-ulex (we now support
1235    stream creation from several kinds of sources).  Overall, the
1236    tools are now quite stable, and their interfaces are unlikely to
1237    change in a way that would break compatibility.  More work,
1238    however, is needed in the documentation.

1244    
1245    Implemented library installer.  Moved CM plugin code for
1246    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1247    their respective trees.  Implemented CM plugin for ml-ulex
1248    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
1249    and ml-antlr.
1250    
1251    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1252    CM tools.  (It turns out to be too messy to do otherwise because
1253    there is too much code that during installation relies on the presence
1254    of these tools -- resulting in a tricky ordering problem.)

1261    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1262    Modified CM's startup code to use shiftArgs as it processes
1263    command line arguments.  This way, the init code in each .sml-file
1264    or library that is mentioned at the top level will see only
1265    those arguments that have not yet been processed at this point.
1266    In other words, the init code can "seize control" and process the
1267    remaining command line.

1334    Description:
1335    
1336    Added code to CM's "standard shell tool" implementation which
1337    causes it to tolerate (with a warning) the situation where the shell
1338    command fails (e.g., due to the shell command's non-existence)
1339    as long as all target files exist.
1340    
1341    This makes it possible to, e.g., build ml-yacc from sources even if
1342    svn checkout messed up the time stamps on files in such a way that
1343    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
1344    be needed to re-process yacc.grm, but obviously it might not yet be
1345    available at that time.)

1427    directory containing two new program generator tools: ml-ulex and
1428    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1429    LL(k) parser generator). These tools are currently "beta-quality"
1430    
1431    The latest versios of the sources can now be obtained anonymously
1432    via subversion.  For this, it is useful to first check out
1433    
1434       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1435    
1436    and put the resulting directory on your shell's PATH.  This provides
1437    access to three shell scripts: checkout-all.sh, stat-all.sh,
1438    and refresh-all.sh.
1439    
1440    To create a freshly checked-out copy of the sources, do
1441    
1442       checkout-all.sh [dir]
1443    
1444    where dir is the optional SML/NJ root directory (default is ".").
1445    
1446    This creates the above directory layout.  Each subdirectory of
1447    the root is under individual subversion control.  The stat-all.sh
1448    and refresh-al.sh scripts apply "svn stat" or "svn update" to
1449    each of these subtrees.

1454    Description:
1455    
1456    Reorganized directory layout.
1457    
1458    This is a temporary solution, more reorganization is to come.
1459    
1460    The basic idea is to have a number of toplevel trees, each corresponding
1461    to a well-defined part of the overall system.  Each part can be
1462    maintained individually, even in separate source repositories,
1463    although currently we still serve everything out of the main
1464    smlnj-gforge tree.
1465    
1466    Installer and and scripts have been updated to reflect the new
1467    layout.  The installer (base/src/system/smlnj/installer) is now
1468    "scriptable" to avoid burning too much knowledge about the
1469    layout into SML source code.  The main script used by the installer
1470    is in config/actions.
1471    
1472    The main change is that many of the subdirectories of what used to
1473    be known as "src" have moved to the toplevel.  The "src" directory
1474    itself has moved down into a subtree called "base".  (We may eventually
1475    get rid of the extra level of indirection represented by "src".)
1476    
1477    The layout is now as follows:
1478    
1479      toplevel tree name | default repository
1480                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1481      -------------------+----------------------------------------------------
1482      config             | $gf/config/trunk
1483                         |
1484      base               | $gf/sml/trunk
1485                         |
1486      smlnj-lib          | $gf/smlnj-lib/trunk
1487      MLRISC             | $gf/MLRISC/trunk
1488                         |
1489      ml-yacc            | $gf/ml-yacc/trunk
1490      ml-lex             | $gf/ml-lex/trunk
1491      ml-burg            | $gf/ml-burg/trunk
1492      lexgen             | $gf/lexgen/trunk
1493      heap2asm           | $gf/heap2asm/trunk
1494                         |
1495      cml                | $gf/cml/trunk
1496      eXene              | $gf/eXene/trunk
1497      ckit               | $gf/ckit/trunk
1498      nlffi              | $gf/nlffi/trunk
1499                         |
1500      smlnj-c            | $gf/smlnj-c/trunk
1501    
1502    In $gf/admin there are a few useful shell scripts for checking out
1503    and maintaining the entire collection of trees:
1504    
1505       admin/checkout-all.sh [dir]
1506          -- optionally creates dir and checks out all trees from their
1507             default repositories; if dir is missing, checkout into .
1508       admin/refresh-all.sh [dir]
1509          -- looks at all trees (from the above list) in dir (default: .)
1510             and runs "svn update" if the tree exists and is under
1511             subversion control;
1512             non-existing or non-subversion trees are skipped
1513       admin/stat-all.sh [dir]
1514          -- like refresh-all.sh, but runs "svn stat" instead

1531    New working version (110.59).  NEW BOOTFILES!
1532    
1533    I am freezing 110.59.  Changes other than the version-number increase:
1534    
1535      eXene:
1536    
1537         * committed changes to eXene from Alley Stoughton:
1538             "fixed bugs in X authorization and resource handling, as well
1539              as in the pile and viewport widgets"
1540    
1541      Runtime:
1542        * fixed linking problem with NetBSD 3.x.
1543    
1544      Lexgen:
1545        * lexgen tool handles non-ascii characters in 7-bit mode the same
1546          way that ml-lex does
1547    
1548        * lexgen propagates exceptions the same way that ml-lex does
1549    
1550      CML:
1551        * Fixed a bug in the SyncVar polling functions (iGetPoll,
1552          mTakePoll, and mGetPoll) that could lead to livelock.

1698    at the time when config/preloads is processed, the library has to
1699    be referred to by another name.  In 110.57 this would be
1700    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm

1757    Description:
1758    
1759    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1760    file gets loaded as a tool -- by the equivalent of CM.make during the
1761    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1762    it.  Instead, it has the status of "user code", so it should use
1763    $/basis.cm to refer to the Basis library.  (At least that's true for
1764    the purpose of bootstrapping the previous change.  In the future it
1765    might make sense to have versiontool.cm refer to
1766    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1767    compiler itself uses.)
1768    
1769    Also patched src/system/testml to have it activate those extra anchor
1770    bindings in config/extrapathconfig.

1775    Tag: blume-22051115-libraries
1776    Description:
1777    
1778    This change affects the way the following libraries are tied into
1779    the system:
1780    
1781       $/basis.cm
1782       $/smlnj-lib.cm
1783       $/pp-lib.cm
1784       $/controls-lib.cm
1785       $/html-lib.cm
1786       $/ml-yacc-lib.cm
1787    
1788    These libraries are now internally (as seen from the source code
1789    of the implementation itself) known by the following names:
1790    
1791       $smlnj/basis/basis.cm
1792       $smlnj/smlnj-lib/smlnj-lib.cm
1793       $smlnj/smlnj-lib/pp-lib.cm
1794       $smlnj/smlnj-lib/controls-lib.cm
1795       $smlnj/smlnj-lib/html-lib.cm
1796       $smlnj/ml-yacc/ml-yacc-lib.cm
1797    
1798    This makes it possible to work with code that requires different
1799    versions of these libraries, and which refers to these libraries using
1800    their "default" names (i.e., the first set of names above).  In other
1801    words, one can un-define or re-define those default names without
1802    compromising the proper functioning of the compiler itself.
1803    
1804    A similar procedure had already been performed for several of the
1805    MLRISC libraries that are linked into the compiler.  I did some
1806    cleanup on this code.
1807    
1808    A new file in the config directory (named extrapathconfig) is
1809    responsible for setting up path anchors that the compiler itself does
1810    not need, but that are typically required by user code.

1989    Tag: blume-20050516-redump-heap
1990    Description:
1991    
1992    Added mechanism for re-creating a heap file for the interactive system
1993    after configuration variables have been changed.
1994    
1995       CM.redump_heap : string -> unit
1996    
1997    This is much like SMLofNJ.exportML, but starting from the resulting
1998    heap does not return to the caller of CM.redump_heap but
1999    restarts the interactive system from scratch.  The original call of
2000    CM.redump_heap does not return but ends the interactive session.
2001    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
2002    
2003    Internally, redump_heap winds the dynamic execution context back to
2004    the point where the original heap image was created and re-executes
2005    the heap image generation code in the boot code.

2121    Tag: blume-20050114-heap2exec
2122    Description:
2123    
2124    Implemented new (but still experimental) heap2exec facility.  This is
2125    tested under Mac OS X and should work under Linux (will test shortly).
2126    It will probably also work on the Sparc (will test some time later).
2127    
2128      - removed old "HACKED_STANDALONE" hack from runtime
2129    
2130    To be able to test this, uncomment the request for "heap2asm" in
2131    config/targets prior to installation.  (Notice that this is different
2132    from "heap2exec" mentioned below.  Not a typo.)
2133    
2134    To perform an actual test, run the command
2135    
2136       $ bin/heap2exec heapfile execfile
2137    
2138    (You can put heap2exec on your shell's path.)
2139    
2140    For example, run
2141    
2142      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2143    
2144    This will create a standalone executable called "mly" which you can
2145    then invoke directly as a command.

2172    
2173    * Fixed CM's incorrect assumption that the PPC is little-endian.

2294    equal to Int64.  The default, however, is unchanged (Position = Int31)
2295    for the time being.
2296    
2297    To enable 64-bit positions, use the following procedure:
2298    
2299    1. Start sml
2300    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2301    3. Type
2302          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2303    4. Run CMB.make() as usual.
2304    
2305    This is barely tested.  The only test so far was a little SML program
2306    counting the number of characters in an 8-gigabyte file by
2307    reading it character-by-character.  That test was successful.
2308    
2309    In support of 64-bit positions, a number of new functions have been
2310    added to the runtime system.

2356    - In a previous commit, fixed a minor issue with how polyequal is being
2357      translated.  In particular, the code now "looks through" abstractions.
2358      This results in slightly fewer polyEqual warnings and hopefully slightly
2359      more efficient code.  Important examples for where this matters are
2360      the new int64 and word64 types.

2390    
2391    Structure Word64 is now (almost) complete, word literals and patterns
2392    seem to work.  There are a few odd pieces missing.  In particular,
2393    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2394    at the moment.
2395    
2396    Making Word64 official would mean that LargeWord becomes Word64.  But
2397    this requires extreme care because most word-word conversions have to
2398    go through LargeWord, so making a mistake means loss of efficiency or
2399    worse.  Eventually there will be a solution similar to (but actually
2400    simpler than) what I did with IntInf.

2436      - Default contents of config/srcarchiveurl uses $VERSION and
2437        normally does not have to be edited to reflect a version change.
2438

2480    Tag: blume-20041020-standalone-backtrace
2481    Description:
2482    
2483    Added a mechanism for getting back-trace information from standalone
2484    programs.  Here is how it works:
2485    
2486       1. The part of the program from which you want to get backtrace
2487          information (usually the whole program) should be wrapped with
2488          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
2489          main program could be modified from something like
2490    
2491             fun main (pgm, args) = ...
2492    
2493         to
2494    
2495            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2496    
2497       2. To be able to access BackTrace.monitor, you have to add
2498          library $smlnj-tdp/plugins.cm to the .cm file that contains your
2499          main function.
2500    
2501       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2502          CM might have created in the past for your project).
2503    
2504       4. Build the system using this command line:
2505    
2506             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2507                      myprog.cm MyProg.main myprog
2508    
2509          instead of the usual
2510    
2511             ml-build myprog.cm MyProg.main myprog
2512    
2513    I changed a library name:
2514    
2515       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2516    
2517    New libraries:
2518    
2519       $smlnj-tdp/back-trace.cm
2520          -- when loaded causes the back-trace plugin to be installed
2521       $smlnj-tdp/coverage.cm
2522          -- when loaded causes the coverage plugin to be installed

2538    Description:
2539    
2540    * Test coverage tool added!
2541    * Further reorganization of tracing-, debugging-, and profiling support:
2542    
2543        - moved original BTImp -- now called BackTrace -- into a separate
2544          library called $/trace-debug-profile.cm
2545        - eliminated all mentions of BTrace from SMLofNJ.Internals
2546        - only the instrumentation mechanism is now left in the compiler proper
2547        - BackTrace module is a plugin which is NOT plugged in by default
2548        - Coverage module is another such plugin
2549    
2550    To get the benefits of any of these plugin modules, the code in
2551    question must be compiled with tdp instrumentation turned on.  This
2552    can be done by setting SMLofNJ.Internals.TDP.mode to true.
2553    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2554    
2555    Plugins are selected at link time.  (Pre-compiled instrumented code
2556    can be re-loaded with different plugins in effect.)  When an
2557    instrumented module is linked, whatever plugins are at that time
2558    enabled will come into effect for that module.
2559    
2560    To enable the back-trace plugin, load library $/trace-debug-profile.cm
2561    and invoke BackTrace.install() (e.g., from the interactive prompt).
2562    To enable the coverage plugin, load the same library and invoke
2563    Coverage.install().
2564    
2565    Back-traces are generated automatically on uncaught exceptions and
2566    when the code in question explicitly invokes BackTrace.trigger().
2567    
2568    Coverage (and execution frequency-) information must be queried
2569    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2592    instrumentation for other purposes.  "TDP" stands for
2593    Trace/Debug/Profile.
2594    
2595    The control flag controlling whether instrumentation is on or off is now

2597    
2598     sml -Cinstrument.btrace-mode=true

2623    
2624    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2625    is supposed to accept a tool argument called "source", but this did
2626    not work because of the clash with the keyword.

2674    
2675    * At the same time, structure CompilerVersion is now known as
2676      structure SMLNJVersion.
2677    
2678    * Arranged for the version tool to NOT kick in when rebuilding the system
2679      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2680      Also, loading the versiontool does not work when rebuilding the system
2681      because CM is not properly initialized at that time.

2687    Description:
2688    
2689    Implemented some CM magic to have
2690        file src/compiler/TopLevel/main/version.sml
2691    generated automagically.
2692    The version is taken from two files: config/version and config/release.
2693    The first is expected to contain a two-part version number such as 110.49.
2694    The second should contain a single number, but it may be missing.
2695    
2696    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2697    time the version tool is loaded (which is the first time you say CMB.make),
2698    then the tool will increment the value stored in config/release every
2699    time CMB.make is invoked.
2700    
2701    The binfile format is now insensitive to anything beyond the first
2702    two components of a version number, so bumping the release does not render
2703    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2704    during development without invalidating existing binfiles.
2705    
2706    In any case, every CMB.make updates the date information in version.sml.
2707    (This is the date that is printed in the banner.)

2730    2.   val set' : 'a control * 'a -> unit -> unit
2731    
2732       stores the given value into the control in stage 2 (i.e., delayed)
2733       but does all error checking in stage 1.
2734       (This is for string controls that need to do parse their argument --
2735        something that might fail.  In some cases, notably in CM, one
2736        already knows the intended argument but wants to delay the actual
2737        assignment until a time when error recovery would be more difficult.)
2738    
2739    Changed the handling of controls in tool arguments to classes "sml" and
2740    "lazysml":
2741       - use Controls.save'restore as a more robust way of restoring the
2742         old value (in particular: without having to re-parse the string)
2743       - use controls to handle the "overload" keyword in the init group
2744         (I believe this change actually fixes a long-standing obscure bug.)

2749    Tag: blume-20040927-lazysml
2750    Description:
2751    
2752    Added a new tool class called "lazysml" to CM's tool chest.  The only
2753    difference to "sml" is that compilation is done with Control.lazysml
2754    set to true.  A source of class "lazysml" is automatically recognized
2755    by a file name suffix of ".lml".
2756    
2757    In addition to the above feature, the original class "sml" now also
2758    supports a tool argument "lazy" which has the same effect.  As a
2759    result, the following three lines are equivalent:
2760    
2761        foo.sml : lazysml
2762        foo.sml : sml (lazy)
2763        foo.sml (lazy)
2764    
2765    The setting goes into effect both during parsing and during
2766    compilation.  The original setting is restored right after parsing and
2767    after compilation, respectively.
2768    
2769    In addition to all the above, there is also a general mechanism to set
2770    ANY of the "controls" that are available at the command line via
2771    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2772    apply as well. (In fact, "lazy" is implemented as a special case of
2773    the general mechanism.)
2774    
2775    The .cm file syntax uses a new keyword tool argument called "with".
2776    There are several ways of indicating the desired settings:
2777    
2778        foo.sml (with:parser.quotations=true)
2779        foo.sml (with:(name:parser.quotations value:true))
2780        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2781        foo.sml (with:(name1=value1 name2=value2 ...))
2782        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2783    
2784        etc.
2785    
2786    Another possible abbreviation is to leave out the =v or value:v part
2787    if the name refers to a boolean control (in which case the value is
2788    taken to be true).  Thus, one could get lazy sml also by saying:
2789    
2790        foo.sml (with:parser.lazy-keyword=true)
2791        foo.sml (with:parser.lazy-keyword)
2792        foo.sml (with:(name:parser.lazy-keyword value:true))
2793        foo.sml (with:(name:parser.lazy-keyword))

3152       The {text,bin}{In,Out}streamOf functions are supposed to create
3153       fresh streams whenever they are called -- as opposed to have them
3154       return the same stream every time.  This design is supposed to
3155       prevent space leaks caused by proc values hanging on to streams.
3156    
3157       The reap function, on the other hand, is supposed to close the
3158       streams.  This cannot be done without having a handle on the
3159       stream in proc after all...
3160    
3161    I took the liberty to implement the following stopgap solution:
3162    
3163      The proc value hangs on to the most recently created stream(s).
3164      Reap closes those.  If either or both of the two streams hadn't
3165      been created at all yet, then reap will close the corresponding
3166      file descriptors directly.
3167    
3168    PS: I don't understand the original space leak argument anymore.  If
3169    a proc hangs on to the imperative stream, then I/O operations on those
3170    will advance the state of the cached stream and avoid the space leak.

3184    Description:
3185    
3186    CM now ignores (but still accepts) the "owner" information in group
3187    descriptions.  The owner of a group is its next enclosing
3188    library. Each group must have a unique owner.  (There is a virtual
3189    "toplevel" library that owns groups which are not nested within a real
3190    library.)  Previously, each group had to explicitly declare its owner,
3191    and CM would check that such a declaration is correct.  The new scheme
3192    is to have CM check that for each group there is precisely one owning
3193    library.
3194    
3195    The advantage of the new scheme is that the programmer no longer needs
3196    to maintain the somewhat annoying owner information.  The downside is
3197    that CM cannot enforce the ownership rule across multiple runs of
3198    CM.make.  Fortunately, enclosing the same group in two different
3199    libraries A and B which are not part of the same program does not
3200    cause real problems.

3219    Description:
3220    
3221    Arranged for ml-build to clean up after itself a little bit better.
3222    The script generates a temporary SML source file and compiles it using
3223    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
3224    gets rid of those at the end, so they don't accumulate under .cm.
3225    
3226    This required a minor change to install.sh because the name of the
3227    metadata directory (default: .cm) is actually configurable at
3228    installation time.

3243    Description:
3244    
3245    Added previously missing support for many socket-related functions
3246    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
3247    for the voluminous patch!
3248    
3249    (I have not tested this patch under win32 yet.)
3250    
3251    Here is David's e-mail:
3252    
3253    Hi,
3254    
3255    Attached to this email you find a diff against sml/nj 110.45
3256    that will enable socket support under Windows.
3257    
3258    To apply the patch (using unix or cygwin)
3259    1) gunzip runtime.diff.gz
3260    2) "cd" into "src/runtime" in the source tree of a fresh
3261       110.45 installation.
3262    3) patch -p 1 < [your/path/to]runtime.diff
3263    
3264    The code compiles fine but has NOT yet been extensively tested.
3265    I only ran a few tests for basic socket client functionality
3266    (which worked fine).  Especially the functions that use ioctl
3267    are not tested at all and might not work (see below).
3268    
3269    I implemented this since we want to move to a newer version of sml/nj
3270    but need socket support in order to use it.  This is the first time I
3271    even had a look at the sml/nj source,  so please review my changes
3272    before making this part of the distribution!  Here are a few issues
3273    that I think might be better for someone to solve who is more
3274    familiar with the sml/nj source (and socket programming):
3275    
3276    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3277      exception since I could not figure out what the windows equivalent
3278      of these functions is
3279    
3280    - In sockets-osdep.h there are a some #include statements that are
3281      only used in a few files that include sockets-osdep.h
3282    
3283    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3284      does not process its return value since I don't know how to
3285      report an error upwards.
3286    
3287    - It would probably be good to have a call to WSACleanup() when
3288      the library is unloaded (if there is such a possibility).
3289      Otherwise I think Windows will take care of this automatically
3290      when the process finishes.
3291    
3292    - I used ioctlsocket() as a replacement for ioctl() but I have
3293      no idea if that is actually the proper replacement on Windows.
3294    
3295    - All these issues are marked in the code by "FIXME" comments.
3296    
3297    We use sml/nj extensively in our products and are quite happy
3298    with it.  I hope this contribution will help you.
3299    
3300    Keep up the good work!
3301

3340    in the "targets" file, then the installer will pull in sources for
3341    everything.  (Notice that this refers to source code only.  Compiled
3342    code is still only installed for modules that were requested explicitly
3343    or which are required for other modules that were requested explicitly.)

3377    Description:
3378    
3379    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
3380    of SML/NJ.  The problem is that
3381    
3382       lib = dlopen(NULL, ...)
3383       f   = dlsym(lib, "malloc");
3384    
3385    does not work on Windows unless we explicitly export symbols
3386    such as 'malloc' during linking.  We fixed this by explicitly
3387    exporting the required symbols with the magic gcc incantation:
3388    
3389        -Wl,--export-all cygwin.def
3390    
3391    where cygwin.def is a file containing all the symbols that
3392    we wish to export.
3393    
3394    I suspect this is a Windows problem and we'll have to
3395    do the same (somehow with windows compilers) when
3396    we build the native win32 version with the system
3397    calls LoadLibrary/GetProcAddress.

3523    Description:
3524    
3525    I modified the read-eval-print loop so that the autoloader gets
3526    invoked whenever the prettyprinter tries to look up a symbol that
3527    is not currently defined in the toplevel environment but which
3528    appears in CM's autoload registry.  As a result, we see far fewer of
3529    those ?.Foo.Bar.xxx names in the prettyprinter's output.
3530    
3531    In addition to this I tried to clean up some pieces of the Basis
3532    implementation (e.g., Socket, Word8Array) in order to prevent other
3533    instances of these ?.Foo.Bar.xxx names from being printed.
3534    
3535    The mechanism that picks names for types still needs some work, though.
3536    (Right now it seems that if there is a type A.t which is defined to
3537    be B.u, but B is unavailable at toplevel, then A.t gets printed as
3538    "?.B.u" although the perhaps more sensible solution would be to use
3539    "A.t" in this case.  In other words, the prettyprinter should follow
3540    a chain of DEFtycs not farther than there are corresponding toplevel
3541    names in the current environment.)
