129    Revision: 3648, 3652
130    Description:
131    
132    1) Change of SourceMap interface.
133       related to fix of off-by-one error in lexer (committed earlier?), and cleanup of noweb code
134       added by Norman Ramsey many years ago (but little used today).
135    
136    3) Slight cleanup of match compiler, eliminatiing compiler/FLINT/tempexpn.sml file that
137       was part of unused implementation of pattern templates (pattern macros).
138    
139    4) Modification of type checker to add "culprit tracking" for improved type error messages
140       (printing of additional culprit information is controlled by ElabControl.showTypeErrorCulprits
141        flag, default false, added in revision 3652).  The culprit tracking needs to be debugged
142        and improved, and the presentation of the culprits needs to be done better.
143    
144    Details in NOTES/changes/dbm_2012_1.

503    not allow the regexps to match any character at all.

819    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
820    
821    Also, changed the handling of "no core access":  When translate.sml
822    needs access to a core exception at a time when the core has not
823    been set up yet (this only happens when compiling system/smlnj/init/*),
824    then don't bother generating the corresponding tests.
825    
826    The old scheme was to generate a bogus value to be used in place of
827    the exception.  Unfortunately, that confuses the plambda type checker.
828    Moreover, it does not do any good, because at runtime we don't expect
829    such an exception to be ever raised.  (The code in system/smlnj/init/*
830    has to be written very carefully with this in mind!)

871    Description:
872    
873    CMB (and CM) now automatically defines the CM "preprocessor" symbol
874    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
875    
876      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
877       CM_SLAVE_MODE is defined in attached slaves while running CM.make
878       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
879       while running CMB.make.  The point is that the single symbol
880       NO_PLUGINS is definde in all three cases.)
881    
882    I changed the three locations within the sources that get compiled
883    during CMB.make where ml-yacc or ml-lex input is processed: When
884    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
885    is bypassed.
886    
887    When bootstrapping new versions of the compiler, there can be
888    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
889    are not available or otherwise not operational.  In this case one can
890    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
891    do so, the following command should be issued at the interactive
892    prompt:
893    
894       #set (CMB.symval "NO_PLUGINS") (SOME 1);
895    
896    A CMB.make with NO_PLUGINS defined relies on the existence of the
897    files that normally would be generated by ml-yacc and ml-lex.
898    (Copies of these files are in the repository.)

916    Changed the installation mechanism for CM tool plugins.  These are
917    just libaries and now get installed like ordinary libaries.
918    
919    There are now a number of new installation targets that give some
920    fine-grain control over what classes and suffixes are known, and what
921    they will map to.
922    See config/targets for details.
923    
924    The code that caused plugin installation as part of running a
925    tool's "build" script has been removed.  (The build script is for
926    building, not for installing.)

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

945    
946    Merge of ml-lpt revisions for 110.64.
947    
948    The name of several ml-lpt-lib modules has changed:
949      Repair        => AntlrRepair
950      StreamPos     => AntlrStreamPos
951      ErrHandlerFn  => AntlrErrHandler
952      EBNF          => AntlrEBNF
953    
954    The ml-antlr specification format has changed: declarations such as
955    %tokens and nonterminal definitions can occur *multiple* times in the
956    same specification.  The semantics are such that each new declaration
957    extends the previous ones.  This does not apply to %start or %name,
958    of course.
959    
960    Importing a grammar via %import now includes *all* declarations in from
961    the imported grammar, except for %name, %entry, and %start.  Tokens
962    and nonterminals can be dropped using the new %dropping clause of the
963    %import directive; the separate %drop and %extend have been removed.
964    
965    We now allow optional type annotations on nonterminals, using the %nonterms
966    directive as in ml-yacc.
967    
968    The refcell construct is now implemented using SML's regular reference
969    cells, so the :== and !! notation has been deprecated.
970    
971    The ml-antlr tool now does much more checking of specifications, and
972    its error messages have been greatly improved.  Error repair for
973    generated parsers has been completely rewritten, and is now both
974    much faster and more accurate.
975    
976    ml-ulex is now more lenient with escape codes (non-SML-standard
977    escape codes are now interpreted literally, so e.g. \| denotes "|").
978    Also, character classes may now include a "-" character at the beginning
979    as is standard in most other regexp tools.
980    
981    All of these changes are documented in the user guide, which has
982    been updated and improved with this merge.

989    
990    Merge of the primop3 branch (base) into the trunk to create 110.63.1.
991    Significant changes in FLINT and the front end, mostly having to do
992    with a reorganized system for handling primops.  Various bug fixes
993    and improvements in printing signatures.

998    Description:
999    
1000    Preliminary commit of large ml-lpt revisions (more to come for 110.64).
1001    The ml-antlr specification format has changed: declarations such as
1002    %tokens and nonterminal definitions can occur *multiple* times in the
1003    same specification.  The semantics are such that each new declaration
1004    extends the previous ones.  Grammar extension constructs have also
1005    changed.  We now allow type annotations on nonterminals.  Finally,
1006    the refcell construct is now implemented using SML's regular reference
1007    cells, so the :== and !! notation has been deprecated.  All of these
1008    changes will appear in the 110.64 user guide for ml-lpt.
1009    
1010    The ml-antlr tool now does much more checking of specifications, and
1011    its error messages have been greatly improved.  There has also been
1012    some work on the error repair process for generated parsers, but this
1013    will be further improved in 110.64.

1023    this effect in Basis/Implementation/string.sml.

1103    
1104    Added preliminary support in MLRISC for Staged Allocation, a technique
1105    for specifying calling conventions (see
1106    http://www.eecs.harvard.edu/~nr/pubs/staged-abstract.html).
1107    Initially, we plan to use this code to generate C calls for the AMD64.
1108    
1109    The staged allocation code base resides in MLRISC/staged-allocation,
1110    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1191    Implemented library installer.  Moved CM plugin code for

1194    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
1195    and ml-antlr.
1196    
1197    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1198    CM tools.  (It turns out to be too messy to do otherwise because
1199    there is too much code that during installation relies on the presence
1200    of these tools -- resulting in a tricky ordering problem.)

1207    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1208    Modified CM's startup code to use shiftArgs as it processes
1209    command line arguments.  This way, the init code in each .sml-file
1210    or library that is mentioned at the top level will see only
1211    those arguments that have not yet been processed at this point.
1212    In other words, the init code can "seize control" and process the
1213    remaining command line.

1280    Description:
1281    
1282    Added code to CM's "standard shell tool" implementation which

1284    command fails (e.g., due to the shell command's non-existence)
1285    as long as all target files exist.
1286    
1287    This makes it possible to, e.g., build ml-yacc from sources even if
1288    svn checkout messed up the time stamps on files in such a way that
1289    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
1290    be needed to re-process yacc.grm, but obviously it might not yet be
1291    available at that time.)

1332    
1333    New working release (110.60).  NEW BOOTFILES!
1334    
1335    This is the first subversion-hosted release.  There are also changes
1336    to the directory layout.  Here is a table:
1337    
1338    (All pathnames are relative to the SML/NJ "root" directory.)
1339    
1340      config -> config
1341    
1342      src/cm -> base/cm
1343      src/compiler -> base/compiler
1344      src/runtime -> base/runtime
1345      src/system -> base/system
1346    
1347      src/cm/pgraph -> pgraph
1348    
1349      src/READMES -> base/READMES
1350      src/$notefile -> base/NOTES/$notefile
1351         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1352                           MACOSXINSTALL WININSTALL
1353    
1354      src/smlnj-lib -> smlnj-lib
1355      src/MLRISC -> MLRISC
1356      ckit -> ckit
1357      src/cml -> cml
1358      src/eXene -> eXene
1359      src/heap2asm -> heap2asm
1360      src/lexgen -> lexgen
1361      src/ml-burg -> ml-burg
1362      src/ml-lex -> ml-lex
1363      src/ml-yacc -> ml-yacc
1364      src/ml-nlffi-lib -> nlffi/lib
1365      src/ml-nlffigen -> nlffi/gen
1366      src/smlnj-c -> smlnj-c
1367      src/tools/TraceDebugProf -> trace-debug-profile
1368    
1369    In addition, there is also a new
1370    
1371      ml-lpt
1372    
1373    directory containing two new program generator tools: ml-ulex and
1374    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1375    LL(k) parser generator). These tools are currently "beta-quality"
1376    
1377    The latest versios of the sources can now be obtained anonymously
1378    via subversion.  For this, it is useful to first check out
1379    
1380       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1381    
1382    and put the resulting directory on your shell's PATH.  This provides
1383    access to three shell scripts: checkout-all.sh, stat-all.sh,
1384    and refresh-all.sh.
1385    
1386    To create a freshly checked-out copy of the sources, do
1387    
1388       checkout-all.sh [dir]
1389    
1390    where dir is the optional SML/NJ root directory (default is ".").
1391    
1392    This creates the above directory layout.  Each subdirectory of
1393    the root is under individual subversion control.  The stat-all.sh
1394    and refresh-al.sh scripts apply "svn stat" or "svn update" to
1395    each of these subtrees.

1400    Description:
1401    
1402    Reorganized directory layout.
1403    
1404    This is a temporary solution, more reorganization is to come.
1405    
1406    The basic idea is to have a number of toplevel trees, each corresponding
1407    to a well-defined part of the overall system.  Each part can be
1408    maintained individually, even in separate source repositories,
1409    although currently we still serve everything out of the main
1410    smlnj-gforge tree.
1411    
1412    Installer and and scripts have been updated to reflect the new
1413    layout.  The installer (base/src/system/smlnj/installer) is now
1414    "scriptable" to avoid burning too much knowledge about the
1415    layout into SML source code.  The main script used by the installer
1416    is in config/actions.
1417    
1418    The main change is that many of the subdirectories of what used to
1419    be known as "src" have moved to the toplevel.  The "src" directory
1420    itself has moved down into a subtree called "base".  (We may eventually
1421    get rid of the extra level of indirection represented by "src".)
1422    
1423    The layout is now as follows:
1424

1459       admin/stat-all.sh [dir]
1460          -- like refresh-all.sh, but runs "svn stat" instead

1476    
1477    New working version (110.59).  NEW BOOTFILES!
1478    
1479    I am freezing 110.59.  Changes other than the version-number increase:
1480    
1481      eXene:
1482    
1483         * committed changes to eXene from Alley Stoughton:
1484             "fixed bugs in X authorization and resource handling, as well
1485              as in the pile and viewport widgets"
1486    
1487      Runtime:
1488        * fixed linking problem with NetBSD 3.x.
1489    
1490      Lexgen:
1491        * lexgen tool handles non-ascii characters in 7-bit mode the same
1492          way that ml-lex does
1493    
1494        * lexgen propagates exceptions the same way that ml-lex does
1495    
1496      CML:
1497        * Fixed a bug in the SyncVar polling functions (iGetPoll,
1498          mTakePoll, and mGetPoll) that could lead to livelock.

1609    (This is a temporary solution which relies on the fact that the

1640    Description:

1642    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
1643    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1644    at the time when config/preloads is processed, the library has to
1645    be referred to by another name.  In 110.57 this would be
1646    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1647    to be valid as well.)

1702    Tag: blume-22051115-versiontool
1703    Description:
1704    
1705    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1706    file gets loaded as a tool -- by the equivalent of CM.make during the
1707    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1708    it.  Instead, it has the status of "user code", so it should use
1709    $/basis.cm to refer to the Basis library.  (At least that's true for
1710    the purpose of bootstrapping the previous change.  In the future it
1711    might make sense to have versiontool.cm refer to
1712    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1713    compiler itself uses.)
1714    
1715    Also patched src/system/testml to have it activate those extra anchor
1716    bindings in config/extrapathconfig.

1721    Tag: blume-22051115-libraries
1722    Description:
1723    
1724    This change affects the way the following libraries are tied into
1725    the system:
1726    
1727       $/basis.cm
1728       $/smlnj-lib.cm
1729       $/pp-lib.cm
1730       $/controls-lib.cm
1731       $/html-lib.cm
1732       $/ml-yacc-lib.cm
1733    
1734    These libraries are now internally (as seen from the source code
1735    of the implementation itself) known by the following names:
1736    
1737       $smlnj/basis/basis.cm
1738       $smlnj/smlnj-lib/smlnj-lib.cm
1739       $smlnj/smlnj-lib/pp-lib.cm
1740       $smlnj/smlnj-lib/controls-lib.cm
1741       $smlnj/smlnj-lib/html-lib.cm
1742       $smlnj/ml-yacc/ml-yacc-lib.cm
1743    
1744    This makes it possible to work with code that requires different
1745    versions of these libraries, and which refers to these libraries using
1746    their "default" names (i.e., the first set of names above).  In other
1747    words, one can un-define or re-define those default names without
1748    compromising the proper functioning of the compiler itself.
1749    
1750    A similar procedure had already been performed for several of the
1751    MLRISC libraries that are linked into the compiler.  I did some
1752    cleanup on this code.
1753    
1754    A new file in the config directory (named extrapathconfig) is
1755    responsible for setting up path anchors that the compiler itself does
1756    not need, but that are typically required by user code.

1935    Tag: blume-20050516-redump-heap
1936    Description:
1937    
1938    Added mechanism for re-creating a heap file for the interactive system
1939    after configuration variables have been changed.
1940    
1941       CM.redump_heap : string -> unit
1942    
1943    This is much like SMLofNJ.exportML, but starting from the resulting
1944    heap does not return to the caller of CM.redump_heap but
1945    restarts the interactive system from scratch.  The original call of
1946    CM.redump_heap does not return but ends the interactive session.
1947    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
1948    
1949    Internally, redump_heap winds the dynamic execution context back to
1950    the point where the original heap image was created and re-executes
1951    the heap image generation code in the boot code.

2067    Tag: blume-20050114-heap2exec
2068    Description:
2069    
2070    Implemented new (but still experimental) heap2exec facility.  This is
2071    tested under Mac OS X and should work under Linux (will test shortly).
2072    It will probably also work on the Sparc (will test some time later).
2073    
2074      - removed old "HACKED_STANDALONE" hack from runtime
2075    
2076    To be able to test this, uncomment the request for "heap2asm" in
2077    config/targets prior to installation.  (Notice that this is different
2078    from "heap2exec" mentioned below.  Not a typo.)
2079    
2080    To perform an actual test, run the command
2081    
2082       $ bin/heap2exec heapfile execfile
2083    
2084    (You can put heap2exec on your shell's path.)
2085    
2086    For example, run
2087    
2088      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2089    
2090    This will create a standalone executable called "mly" which you can
2091    then invoke directly as a command.

2116    (The parameter-passing part of the picture has not complete. But
2117    data structure access seems to work.)
2118    
2119    * Fixed CM's incorrect assumption that the PPC is little-endian.
2120      (On the Mac, it is big-endian.  And that's currently our only
2121      PPC platform.)

2138    
2139        The Unix I/O library of SML/NJ on cygwin does not understand
2140    Windows style pathname, so problems arise when SMLNJ_HOME is set
2141    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
2142    to a POSIX pathname on cygwin.

2236    Tag: blume-20041124-position
2237    Description:
2238    
2239    The compiler can now be compiled in a mode that makes structure Position
2240    equal to Int64.  The default, however, is unchanged (Position = Int31)
2241    for the time being.
2242    
2243    To enable 64-bit positions, use the following procedure:
2244    
2245    1. Start sml
2246    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2247    3. Type
2248          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2249    4. Run CMB.make() as usual.
2250    
2251    This is barely tested.  The only test so far was a little SML program
2252    counting the number of characters in an 8-gigabyte file by
2253    reading it character-by-character.  That test was successful.
2254    
2255    In support of 64-bit positions, a number of new functions have been
2256    added to the runtime system.

2297    Description:
2298    
2299    - Stripped down the versiontool: It now only handles the version number.
2300      The date string is generated at bootstrap time (during makeml).
2301    
2302    - In a previous commit, fixed a minor issue with how polyequal is being
2303      translated.  In particular, the code now "looks through" abstractions.
2304      This results in slightly fewer polyEqual warnings and hopefully slightly
2305      more efficient code.  Important examples for where this matters are
2306      the new int64 and word64 types.

2322    
2323    All the pieces of Word64 are now there, with the exception of the
2324    conversions from and to LargeWord. (Eventually these need to be identities,
2325    but for the time being they don't even make sense because LargeWord is
2326    32-bit wide.)
2327    
2328    Also started to add similar support for Int64, but major pieces of that
2329    are still missing.

2335    Description:
2336    
2337    Structure Word64 is now (almost) complete, word literals and patterns
2338    seem to work.  There are a few odd pieces missing.  In particular,
2339    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2340    at the moment.
2341    
2342    Making Word64 official would mean that LargeWord becomes Word64.  But
2343    this requires extreme care because most word-word conversions have to
2344    go through LargeWord, so making a mistake means loss of efficiency or
2345    worse.  Eventually there will be a solution similar to (but actually
2346    simpler than) what I did with IntInf.

2376    Also:
2377    
2378      - Changend config/srcarchiveurl from a file just
2379        containing the URL string into a file containing
2380        shell script code.  The code has access to the $VERSION variable.
2381      - Made corresponding changes to config/install.sh and config/unpack.
2382      - Default contents of config/srcarchiveurl uses $VERSION and
2383        normally does not have to be edited to reflect a version change.
2384    
2385      (As a result, a version change can be done by just editing
2386       config/version, the rest is now automatic.)

2426    Tag: blume-20041020-standalone-backtrace
2427    Description:
2428    
2429    Added a mechanism for getting back-trace information from standalone
2430    programs.  Here is how it works:
2431    
2432       1. The part of the program from which you want to get backtrace
2433          information (usually the whole program) should be wrapped with
2434          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
2435          main program could be modified from something like
2436    
2437             fun main (pgm, args) = ...
2438    
2439         to
2440    
2441            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2442    
2443       2. To be able to access BackTrace.monitor, you have to add
2444          library $smlnj-tdp/plugins.cm to the .cm file that contains your
2445          main function.
2446    
2447       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2448          CM might have created in the past for your project).
2449    
2450       4. Build the system using this command line:
2451    
2452             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2453                      myprog.cm MyProg.main myprog
2454    
2455          instead of the usual
2456    
2457             ml-build myprog.cm MyProg.main myprog
2458    
2459    I changed a library name:
2460    
2461       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2462    
2463    New libraries:
2464    
2465       $smlnj-tdp/back-trace.cm
2466          -- when loaded causes the back-trace plugin to be installed
2467       $smlnj-tdp/coverage.cm
2468          -- when loaded causes the coverage plugin to be installed

2484    Description:
2485    
2486    * Test coverage tool added!
2487    * Further reorganization of tracing-, debugging-, and profiling support:
2488    
2489        - moved original BTImp -- now called BackTrace -- into a separate
2490          library called $/trace-debug-profile.cm
2491        - eliminated all mentions of BTrace from SMLofNJ.Internals
2492        - only the instrumentation mechanism is now left in the compiler proper
2493        - BackTrace module is a plugin which is NOT plugged in by default
2494        - Coverage module is another such plugin
2495    
2496    To get the benefits of any of these plugin modules, the code in
2497    question must be compiled with tdp instrumentation turned on.  This
2498    can be done by setting SMLofNJ.Internals.TDP.mode to true.
2499    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2500    
2501    Plugins are selected at link time.  (Pre-compiled instrumented code
2502    can be re-loaded with different plugins in effect.)  When an
2503    instrumented module is linked, whatever plugins are at that time
2504    enabled will come into effect for that module.
2505    
2506    To enable the back-trace plugin, load library $/trace-debug-profile.cm
2507    and invoke BackTrace.install() (e.g., from the interactive prompt).
2508    To enable the coverage plugin, load the same library and invoke
2509    Coverage.install().
2510    
2511    Back-traces are generated automatically on uncaught exceptions and
2512    when the code in question explicitly invokes BackTrace.trigger().
2513    
2514    Coverage (and execution frequency-) information must be queried
2515    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2537    This is is preparation of using the original back-trace
2538    instrumentation for other purposes.  "TDP" stands for
2539    Trace/Debug/Profile.
2540    
2541    The control flag controlling whether instrumentation is on or off is now
2542    registered under a different name, so instead of running sml as
2543    
2544     sml -Cinstrument.btrace-mode=true
2545

2567    treats subsequent occurrences of "group", "library", "source", "is",
2568    "*", and "-" as ordinary identifiers rather than keywords.
2569    
2570    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2571    is supposed to accept a tool argument called "source", but this did
2572    not work because of the clash with the keyword.

2619      a stable src/compiler/core.cm.
2620    
2621    * At the same time, structure CompilerVersion is now known as
2622      structure SMLNJVersion.
2623    
2624    * Arranged for the version tool to NOT kick in when rebuilding the system
2625      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2626      Also, loading the versiontool does not work when rebuilding the system
2627      because CM is not properly initialized at that time.

2632    Tag: blume-20040929-autoversion
2633    Description:
2634    
2635    Implemented some CM magic to have
2636        file src/compiler/TopLevel/main/version.sml
2637    generated automagically.
2638    The version is taken from two files: config/version and config/release.
2639    The first is expected to contain a two-part version number such as 110.49.
2640    The second should contain a single number, but it may be missing.
2641    
2642    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2643    time the version tool is loaded (which is the first time you say CMB.make),
2644    then the tool will increment the value stored in config/release every
2645    time CMB.make is invoked.
2646    
2647    The binfile format is now insensitive to anything beyond the first
2648    two components of a version number, so bumping the release does not render
2649    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2650    during development without invalidating existing binfiles.
2651    
2652    In any case, every CMB.make updates the date information in version.sml.
2653    (This is the date that is printed in the banner.)

2666    Tag: blume-20040927-controls
2667    Description:
2668    
2669    Added two pieces of functionality to the Controls interface:
2670    
2671    1.   val save'restore: 'a control -> unit -> unit
2672    
2673       grabs the current value of the control in stage 1 and restores it
2674       in stage 2.
2675    
2676    2.   val set' : 'a control * 'a -> unit -> unit
2677    
2678       stores the given value into the control in stage 2 (i.e., delayed)
2679       but does all error checking in stage 1.
2680       (This is for string controls that need to do parse their argument --
2681        something that might fail.  In some cases, notably in CM, one
2682        already knows the intended argument but wants to delay the actual
2683        assignment until a time when error recovery would be more difficult.)
2684    
2685    Changed the handling of controls in tool arguments to classes "sml" and
2686    "lazysml":
2687       - use Controls.save'restore as a more robust way of restoring the
2688         old value (in particular: without having to re-parse the string)
2689       - use controls to handle the "overload" keyword in the init group
2690         (I believe this change actually fixes a long-standing obscure bug.)

2695    Tag: blume-20040927-lazysml
2696    Description:
2697    
2698    Added a new tool class called "lazysml" to CM's tool chest.  The only
2699    difference to "sml" is that compilation is done with Control.lazysml
2700    set to true.  A source of class "lazysml" is automatically recognized
2701    by a file name suffix of ".lml".
2702    
2703    In addition to the above feature, the original class "sml" now also
2704    supports a tool argument "lazy" which has the same effect.  As a
2705    result, the following three lines are equivalent:
2706    
2707        foo.sml : lazysml
2708        foo.sml : sml (lazy)
2709        foo.sml (lazy)
2710    
2711    The setting goes into effect both during parsing and during
2712    compilation.  The original setting is restored right after parsing and
2713    after compilation, respectively.
2714    
2715    In addition to all the above, there is also a general mechanism to set
2716    ANY of the "controls" that are available at the command line via
2717    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2718    apply as well. (In fact, "lazy" is implemented as a special case of
2719    the general mechanism.)
2720    
2721    The .cm file syntax uses a new keyword tool argument called "with".
2722    There are several ways of indicating the desired settings:
2723    
2724        foo.sml (with:parser.quotations=true)
2725        foo.sml (with:(name:parser.quotations value:true))
2726        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2727        foo.sml (with:(name1=value1 name2=value2 ...))
2728        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2729    
2730        etc.
2731    
2732    Another possible abbreviation is to leave out the =v or value:v part
2733    if the name refers to a boolean control (in which case the value is
2734    taken to be true).  Thus, one could get lazy sml also by saying:
2735    
2736        foo.sml (with:parser.lazy-keyword=true)
2737        foo.sml (with:parser.lazy-keyword)
2738        foo.sml (with:(name:parser.lazy-keyword value:true))
2739        foo.sml (with:(name:parser.lazy-keyword))

3091    Description:
3092    
3093    Changed the interface of structures Timer and Unix to match the most
3094    recent Basis spec.
3095    
3096    In the case of Unix there still seems to be an open/weird issue:
3097    
3098       The {text,bin}{In,Out}streamOf functions are supposed to create
3099       fresh streams whenever they are called -- as opposed to have them
3100       return the same stream every time.  This design is supposed to
3101       prevent space leaks caused by proc values hanging on to streams.
3102    
3103       The reap function, on the other hand, is supposed to close the
3104       streams.  This cannot be done without having a handle on the
3105       stream in proc after all...
3106    
3107    I took the liberty to implement the following stopgap solution:
3108    
3109      The proc value hangs on to the most recently created stream(s).
3110      Reap closes those.  If either or both of the two streams hadn't
3111      been created at all yet, then reap will close the corresponding
3112      file descriptors directly.
3113    
3114    PS: I don't understand the original space leak argument anymore.  If
3115    a proc hangs on to the imperative stream, then I/O operations on those
3116    will advance the state of the cached stream and avoid the space leak.

3130    Description:
3131    
3132    CM now ignores (but still accepts) the "owner" information in group
3133    descriptions.  The owner of a group is its next enclosing
3134    library. Each group must have a unique owner.  (There is a virtual
3135    "toplevel" library that owns groups which are not nested within a real
3136    library.)  Previously, each group had to explicitly declare its owner,
3137    and CM would check that such a declaration is correct.  The new scheme
3138    is to have CM check that for each group there is precisely one owning
3139    library.
3140    
3141    The advantage of the new scheme is that the programmer no longer needs
3142    to maintain the somewhat annoying owner information.  The downside is
3143    that CM cannot enforce the ownership rule across multiple runs of
3144    CM.make.  Fortunately, enclosing the same group in two different
3145    libraries A and B which are not part of the same program does not
3146    cause real problems.

3152    Description:
3153    
3154    Made the win32 version work again.  (Strangely, a misplaced comma had
3155    slipped into win32-process.c which prevented the runtime from being
3156    compiled correctly.)
3157    
3158    Also, included a minor addition to ml-build.bat analogous to what was
3159    done in blume-20040519-ml-build.

3165    Description:
3166    
3167    Arranged for ml-build to clean up after itself a little bit better.
3168    The script generates a temporary SML source file and compiles it using
3169    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
3170    gets rid of those at the end, so they don't accumulate under .cm.
3171    
3172    This required a minor change to install.sh because the name of the
3173    metadata directory (default: .cm) is actually configurable at
3174    installation time.

3189    Description:
3190    
3191    Added previously missing support for many socket-related functions
3192    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
3193    for the voluminous patch!
3194    
3195    (I have not tested this patch under win32 yet.)
3196    
3197    Here is David's e-mail:
3198    
3199    Hi,
3200    
3201    Attached to this email you find a diff against sml/nj 110.45
3202    that will enable socket support under Windows.
3203    
3204    To apply the patch (using unix or cygwin)
3205    1) gunzip runtime.diff.gz
3206    2) "cd" into "src/runtime" in the source tree of a fresh
3207       110.45 installation.
3208    3) patch -p 1 < [your/path/to]runtime.diff
3209    
3210    The code compiles fine but has NOT yet been extensively tested.
3211    I only ran a few tests for basic socket client functionality
3212    (which worked fine).  Especially the functions that use ioctl
3213    are not tested at all and might not work (see below).
3214    
3215    I implemented this since we want to move to a newer version of sml/nj
3216    but need socket support in order to use it.  This is the first time I
3217    even had a look at the sml/nj source,  so please review my changes
3218    before making this part of the distribution!  Here are a few issues
3219    that I think might be better for someone to solve who is more
3220    familiar with the sml/nj source (and socket programming):
3221    
3222    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3223      exception since I could not figure out what the windows equivalent
3224      of these functions is
3225    
3226    - In sockets-osdep.h there are a some #include statements that are
3227      only used in a few files that include sockets-osdep.h
3228    
3229    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3230      does not process its return value since I don't know how to
3231      report an error upwards.
3232    
3233    - It would probably be good to have a call to WSACleanup() when
3234      the library is unloaded (if there is such a possibility).
3235      Otherwise I think Windows will take care of this automatically
3236      when the process finishes.
3237    
3238    - I used ioctlsocket() as a replacement for ioctl() but I have
3239      no idea if that is actually the proper replacement on Windows.
3240    
3241    - All these issues are marked in the code by "FIXME" comments.
3242    
3243    We use sml/nj extensively in our products and are quite happy
3244    with it.  I hope this contribution will help you.
3245    
3246    Keep up the good work!
3247

3283    The installer now honors the "src-smlnj" target again, although its meaning
3284    has changed from "all sources required for the compiler" to "all sources
3285    the installer knows about".  In other words, if you enable "src-smlnj"
3286    in the "targets" file, then the installer will pull in sources for
3287    everything.  (Notice that this refers to source code only.  Compiled
3288    code is still only installed for modules that were requested explicitly
3289    or which are required for other modules that were requested explicitly.)

3323    Description:
3324    
3325    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
3326    of SML/NJ.  The problem is that
3327    
3328       lib = dlopen(NULL, ...)
3329       f   = dlsym(lib, "malloc");
3330    
3331    does not work on Windows unless we explicitly export symbols
3332    such as 'malloc' during linking.  We fixed this by explicitly
3333    exporting the required symbols with the magic gcc incantation:
3334    
3335        -Wl,--export-all cygwin.def
3336    
3337    where cygwin.def is a file containing all the symbols that
3338    we wish to export.
3339    
3340    I suspect this is a Windows problem and we'll have to
3341    do the same (somehow with windows compilers) when
3342    we build the native win32 version with the system
3343    calls LoadLibrary/GetProcAddress.

3414    (The mechanism was broken and could not be fixed easily.  Moreover,
3415    there does not seem to be any reason not to move all libraries into
3416    lib during installation.  I originally implemented this directive as a
3417    backward-compatibility feature when I first introduced the new CM.
3418    Now that things have been stable for a long time and going back to the
3419    old CM is not an option, there is no reason to keep it around.)

3469    Description:
3470    
3471    I modified the read-eval-print loop so that the autoloader gets
3472    invoked whenever the prettyprinter tries to look up a symbol that
3473    is not currently defined in the toplevel environment but which
3474    appears in CM's autoload registry.  As a result, we see far fewer of
3475    those ?.Foo.Bar.xxx names in the prettyprinter's output.
3476    
3477    In addition to this I tried to clean up some pieces of the Basis
3478    implementation (e.g., Socket, Word8Array) in order to prevent other
3479    instances of these ?.Foo.Bar.xxx names from being printed.
3480    
3481    The mechanism that picks names for types still needs some work, though.
3482    (Right now it seems that if there is a type A.t which is defined to
3483    be B.u, but B is unavailable at toplevel, then A.t gets printed as
3484    "?.B.u" although the perhaps more sensible solution would be to use
3485    "A.t" in this case.  In other words, the prettyprinter should follow
3486    a chain of DEFtycs not farther than there are corresponding toplevel
3487    names in the current environment.)

3493    Description:
3494    
3495    Another installer tweak:  All the ML code for the installer is now
3496    compiled during CMB.make and put into a little library called
3497    $smlnj/installer.cm.  The installation then simply invokes
3498    
3499       sml -m $smlnj/installer.cm
3500    
3501    and everything happens automagically.
3502    
3503    Win32:  ML code senses value of environment variable SMLNJ_HOME.
3504    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
3505            and BINDIR.
3506    
3507    The new scheme guarantees that the ML code responsible for the installation
3508    is in sync with the APIs of the main system.  Also, the installer is
3509    somewhat faster because the installer script is precompiled.

3526    Tag: blume-20030924-sockets
3527    Description:
3528    
3529    1. Fixed SOCKET API and implementation to match Basis spec.
3530       This required changing the internal representation of sockets to one
3531       that remembers (for each socket file descriptor) whether it is currently
3532       blocking or non-blocking.  This state is maintained lazily (i.e., a system
3533       call is made only if the state actually needs to change).
3534    
3535    2. OS-specific details of sockets were moved into separate files, thus
3536       making it possible to unify the bulk of the socket implementations
3537       between Unix and Win32.
3538    
3539    3. CML's socket API changed accordingly.
3540       (Note that we need to remove non-blocking functions from this API
3541       since they are redundant in the case of CML!)
3542    
3543    4. CML's socket implementation now makes use of non-blocking functions
3544       provided by Basis, thus removing all OS-dependent code from this part
3545       of CML.
3546    
3547    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.
