25    Description:
26    
27    Added -D_FILE_OFFSET_BITS=64 flag to x86-linux makefile.  This flag
28    is necessary to avoid spurious EOVERFLOW errors on some versions of
29    Linux.  The problem appears to be limited to large file systems that
30    have more than 2^32 inodes.

50    Date: 2014/08/19
51    Description:
52    Compiling the runtime system on cygwin was failing because the file
53    exceptions.h was missing.  It appears to have been part of previous
54    versions, so a version has been incorporated verbatim in the
55    runtime/mach-base/cygwin-fault.c file (fixes bug #125).

58    Name: John Reppy (http://cs.uchicago.edu/~jhr)
59    Date: 2014/08/19
60    Description:
61    Added the actionToString' and repairToString' functions
62    to the AntlrRepair structure.  These functions allow one to
63    specialize the printing of tokens based on whether they are
64    being added or deleted.

75    Date: 2014/08/17
76    Description:
77    Use mkstemp to implement OS.FileSys.tmpName() on systems that support
78    it (should be all modern versions of Unix).  This change fixes bug #128.
79    (Thanks to Johannes 5 Joemann).

89    Name: John Reppy (http://cs.uchicago.edu/~jhr)
90    Date: 2014/08/14
91    Description:
92    Fixed a problem in the CPS contraction phase.  An optimization that
93    eliminates construction of a record that already exists was not
94    checking that the existing record was the same record kind (bug #119).

97    Name: John Reppy (http://cs.uchicago.edu/~jhr)
98    Date: 2014/07/28
99    Description:
100    Switch to using MAP_ANONYMOUS to allocate memory on Linux systems.
101    This change avoids problems when "/dev" does not support execute
102    permission (as seems to be the case with some versions of Linux
103    running on ChromeBooks; bug #120).

113    Date: 2014/06/07
114    Description:
115    Fixed a long-standing bug in Socket.recvVec, which prevented the result
116    from being used in a string pattern match (thanks to Vesa Norrman
117    for the fix).

127    Name: John Reppy (http://cs.uchicago.edu/~jhr)
128    Date: 2013/11/25
129    Description:
130    Added PackWord{16,32}{Big,Little} structures to the Unsafe module.
131    This change makes the UNSAFE signature closer to the MLton version,
132    although we still need the PackReal structures.

151    Date: 2013/06/04
152    Description:
153    Fix bug #111 (Socket.acceptNB returns somewhat broken sockets).
154    The problem was that under Win32, sockets returned from accept inherit
155    their parents' non-blocking status, whereas on UNIX they are always
156    blocking.

168    Date: 2013/05/02
169    Description:
170    Fix bug #116 (Socket.sameDesc raises Match exception).
171    The problem is that on Windows the iodesc datatype (defined in
172    Basis/Implementation/Win32/pre-os.sml) has both an IODesc constructor
173    and a SockDesc constructor.  Updated the code in Win32/os-io.sml to
174    handle the SockDesc constructor.

296    Description:
297    
298    1) Change of SourceMap interface.
299       related to fix of off-by-one error in lexer (committed earlier?), and cleanup of noweb code
300       added by Norman Ramsey many years ago (but little used today).
301    
302    3) Slight cleanup of match compiler, eliminatiing compiler/FLINT/tempexpn.sml file that
303       was part of unused implementation of pattern templates (pattern macros).
304    
305    4) Modification of type checker to add "culprit tracking" for improved type error messages
306       (printing of additional culprit information is controlled by ElabControl.showTypeErrorCulprits
307        flag, default false, added in revision 3652).  The culprit tracking needs to be debugged
308        and improved, and the presentation of the culprits needs to be done better.

985    Fixed some bugs in new Div code in FLINT/trans/translate.sml.
986    
987    Also, changed the handling of "no core access":  When translate.sml
988    needs access to a core exception at a time when the core has not
989    been set up yet (this only happens when compiling system/smlnj/init/*),
990    then don't bother generating the corresponding tests.
991    
992    The old scheme was to generate a bogus value to be used in place of
993    the exception.  Unfortunately, that confuses the plambda type checker.
994    Moreover, it does not do any good, because at runtime we don't expect
995    such an exception to be ever raised.  (The code in system/smlnj/init/*
996    has to be written very carefully with this in mind!)

1010    FLINT/trans/translate.sml now wraps all DIV/MOD/QUOT/REM operations
1011    with an explicit test for zero division.  This should fixes several
1012    regressions and makes it possible for downstream optimization phases
1013    to treat these operations as "pure" when they are applied to unsigned
1014    operands.

1037    Description:
1038    
1039    CMB (and CM) now automatically defines the CM "preprocessor" symbol
1040    NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
1041    
1042      (In addition, CMB_REBUILD_MODE is defined for makeml -rebuild,
1043       CM_SLAVE_MODE is defined in attached slaves while running CM.make
1044       or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
1045       while running CMB.make.  The point is that the single symbol
1046       NO_PLUGINS is definde in all three cases.)
1047    
1048    I changed the three locations within the sources that get compiled
1049    during CMB.make where ml-yacc or ml-lex input is processed: When
1050    NO_PLUGINS defined, then the use of the mlyacc and mllex tools
1051    is bypassed.
1052    
1053    When bootstrapping new versions of the compiler, there can be
1054    situations where the plugin tools for ml-yacc and ml-lex (or ml-ulex)
1055    are not available or otherwise not operational.  In this case one can
1056    manually define the NO_PLUGINS symbol prior to running CMB.make().  To
1057    do so, the following command should be issued at the interactive
1058    prompt:
1059    
1060       #set (CMB.symval "NO_PLUGINS") (SOME 1);
1061    
1062    A CMB.make with NO_PLUGINS defined relies on the existence of the
1063    files that normally would be generated by ml-yacc and ml-lex.
1064    (Copies of these files are in the repository.)

1081    
1082    Changed the installation mechanism for CM tool plugins.  These are
1083    just libaries and now get installed like ordinary libaries.
1084    
1085    There are now a number of new installation targets that give some
1086    fine-grain control over what classes and suffixes are known, and what
1087    they will map to.
1088    See config/targets for details.
1089    
1090    The code that caused plugin installation as part of running a
1091    tool's "build" script has been removed.  (The build script is for
1092    building, not for installing.)

1098    
1099    Added a boolean control named cm.tolerate-tool-failures (env. variable
1100    name: CM_TOLERATE_TOOL_FAILURES).  The default is false and makes
1101    CM fail if a shell tool reports a non-success exit status.  If
1102    the control is set to true, then CM will press on after tool failures
1103    in the event that the target files exist (even though they are
1104    considered outdated).  Turning the control to true can be useful for
1105    bootstrapping.

1110    Description:
1111    
1112    Merge of ml-lpt revisions for 110.64.
1113    
1114    The name of several ml-lpt-lib modules has changed:
1115      Repair        => AntlrRepair
1116      StreamPos     => AntlrStreamPos
1117      ErrHandlerFn  => AntlrErrHandler
1118      EBNF          => AntlrEBNF
1119    
1120    The ml-antlr specification format has changed: declarations such as
1121    %tokens and nonterminal definitions can occur *multiple* times in the
1122    same specification.  The semantics are such that each new declaration
1123    extends the previous ones.  This does not apply to %start or %name,
1124    of course.
1125    
1126    Importing a grammar via %import now includes *all* declarations in from
1127    the imported grammar, except for %name, %entry, and %start.  Tokens
1128    and nonterminals can be dropped using the new %dropping clause of the
1129    %import directive; the separate %drop and %extend have been removed.
1130    
1131    We now allow optional type annotations on nonterminals, using the %nonterms
1132    directive as in ml-yacc.
1133    
1134    The refcell construct is now implemented using SML's regular reference
1135    cells, so the :== and !! notation has been deprecated.
1136    
1137    The ml-antlr tool now does much more checking of specifications, and
1138    its error messages have been greatly improved.  Error repair for
1139    generated parsers has been completely rewritten, and is now both
1140    much faster and more accurate.
1141    
1142    ml-ulex is now more lenient with escape codes (non-SML-standard
1143    escape codes are now interpreted literally, so e.g. \| denotes "|").
1144    Also, character classes may now include a "-" character at the beginning
1145    as is standard in most other regexp tools.
1146    
1147    All of these changes are documented in the user guide, which has
1148    been updated and improved with this merge.

1165    
1166    Preliminary commit of large ml-lpt revisions (more to come for 110.64).
1167    The ml-antlr specification format has changed: declarations such as
1168    %tokens and nonterminal definitions can occur *multiple* times in the
1169    same specification.  The semantics are such that each new declaration
1170    extends the previous ones.  Grammar extension constructs have also
1171    changed.  We now allow type annotations on nonterminals.  Finally,
1172    the refcell construct is now implemented using SML's regular reference
1173    cells, so the :== and !! notation has been deprecated.  All of these
1174    changes will appear in the 110.64 user guide for ml-lpt.
1175    
1176    The ml-antlr tool now does much more checking of specifications, and
1177    its error messages have been greatly improved.  There has also been
1178    some work on the error repair process for generated parsers, but this
1179    will be further improved in 110.64.

1271    for specifying calling conventions (see

1273    Initially, we plan to use this code to generate C calls for the AMD64.
1274    
1275    The staged allocation code base resides in MLRISC/staged-allocation,
1276    and specialized calling conventions go in MLRISC/ARCH/staged-allocation.

1346    the interface for creating streams in ml-ulex (we now support
1347    stream creation from several kinds of sources).  Overall, the

1356    
1357    Implemented library installer.  Moved CM plugin code for
1358    ml-burg, ml-lex, and ml-yacc out of CM source tree and into
1359    their respective trees.  Implemented CM plugin for ml-ulex
1360    and ml-antlr.  Used library installer for ml-burg, ml-ulex,
1361    and ml-antlr.
1362    
1363    For ml-yacc and ml-lex we continue to have permanently "plugged-in"
1364    CM tools.  (It turns out to be too messy to do otherwise because
1365    there is too much code that during installation relies on the presence
1366    of these tools -- resulting in a tricky ordering problem.)

1373    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
1374    Modified CM's startup code to use shiftArgs as it processes
1375    command line arguments.  This way, the init code in each .sml-file
1376    or library that is mentioned at the top level will see only
1377    those arguments that have not yet been processed at this point.
1378    In other words, the init code can "seize control" and process the
1379    remaining command line.

1437    Fixed the code in runtime/c-libs/posix-tty/{tcgetattr,tcsetattr}.c to
1438    get the c_cc termios data copied correctly.  Also moved the allocation
1439    of the string to avoid problems if it caused a GC.
1440    
1441    Thanks to Timothy Bourke for the bug report and fix.

1446    Description:
1447    
1448    Added code to CM's "standard shell tool" implementation which
1449    causes it to tolerate (with a warning) the situation where the shell
1450    command fails (e.g., due to the shell command's non-existence)
1451    as long as all target files exist.
1452    
1453    This makes it possible to, e.g., build ml-yacc from sources even if
1454    svn checkout messed up the time stamps on files in such a way that
1455    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
1456    be needed to re-process yacc.grm, but obviously it might not yet be
1457    available at that time.)

1497    Description:
1498    
1499    New working release (110.60).  NEW BOOTFILES!
1500    
1501    This is the first subversion-hosted release.  There are also changes
1502    to the directory layout.  Here is a table:
1503    
1504    (All pathnames are relative to the SML/NJ "root" directory.)
1505    
1506      config -> config
1507    
1508      src/cm -> base/cm
1509      src/compiler -> base/compiler
1510      src/runtime -> base/runtime
1511      src/system -> base/system
1512    
1513      src/cm/pgraph -> pgraph
1514    
1515      src/READMES -> base/READMES
1516      src/$notefile -> base/NOTES/$notefile
1517         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
1518                           MACOSXINSTALL WININSTALL
1519    
1520      src/smlnj-lib -> smlnj-lib
1521      src/MLRISC -> MLRISC
1522      ckit -> ckit
1523      src/cml -> cml
1524      src/eXene -> eXene
1525      src/heap2asm -> heap2asm
1526      src/lexgen -> lexgen
1527      src/ml-burg -> ml-burg
1528      src/ml-lex -> ml-lex
1529      src/ml-yacc -> ml-yacc
1530      src/ml-nlffi-lib -> nlffi/lib
1531      src/ml-nlffigen -> nlffi/gen
1532      src/smlnj-c -> smlnj-c
1533      src/tools/TraceDebugProf -> trace-debug-profile
1534    
1535    In addition, there is also a new
1536    
1537      ml-lpt
1538    
1539    directory containing two new program generator tools: ml-ulex and
1540    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
1541    LL(k) parser generator). These tools are currently "beta-quality"
1542    
1543    The latest versios of the sources can now be obtained anonymously
1544    via subversion.  For this, it is useful to first check out
1545    
1546       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1547    
1548    and put the resulting directory on your shell's PATH.  This provides
1549    access to three shell scripts: checkout-all.sh, stat-all.sh,
1550    and refresh-all.sh.
1551    
1552    To create a freshly checked-out copy of the sources, do
1553    
1554       checkout-all.sh [dir]
1555    
1556    where dir is the optional SML/NJ root directory (default is ".").
1557    
1558    This creates the above directory layout.  Each subdirectory of
1559    the root is under individual subversion control.  The stat-all.sh
1560    and refresh-al.sh scripts apply "svn stat" or "svn update" to
1561    each of these subtrees.
1562

1565    Date: 2006/11/02 12:20:00 CST
1566    Description:
1567    
1568    Reorganized directory layout.
1569    
1570    This is a temporary solution, more reorganization is to come.
1571    
1572    The basic idea is to have a number of toplevel trees, each corresponding
1573    to a well-defined part of the overall system.  Each part can be
1574    maintained individually, even in separate source repositories,
1575    although currently we still serve everything out of the main
1576    smlnj-gforge tree.
1577    
1578    Installer and and scripts have been updated to reflect the new
1579    layout.  The installer (base/src/system/smlnj/installer) is now
1580    "scriptable" to avoid burning too much knowledge about the
1581    layout into SML source code.  The main script used by the installer
1582    is in config/actions.
1583    
1584    The main change is that many of the subdirectories of what used to
1585    be known as "src" have moved to the toplevel.  The "src" directory
1586    itself has moved down into a subtree called "base".  (We may eventually
1587    get rid of the extra level of indirection represented by "src".)
1588    
1589    The layout is now as follows:
1590    
1591      toplevel tree name | default repository
1592                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
1593      -------------------+----------------------------------------------------
1594      config             | $gf/config/trunk
1595                         |
1596      base               | $gf/sml/trunk
1597                         |
1598      smlnj-lib          | $gf/smlnj-lib/trunk
1599      MLRISC             | $gf/MLRISC/trunk
1600                         |
1601      ml-yacc            | $gf/ml-yacc/trunk
1602      ml-lex             | $gf/ml-lex/trunk
1603      ml-burg            | $gf/ml-burg/trunk
1604      lexgen             | $gf/lexgen/trunk
1605      heap2asm           | $gf/heap2asm/trunk
1606                         |
1607      cml                | $gf/cml/trunk
1608      eXene              | $gf/eXene/trunk
1609      ckit               | $gf/ckit/trunk
1610      nlffi              | $gf/nlffi/trunk
1611                         |
1612      smlnj-c            | $gf/smlnj-c/trunk
1613    
1614    In $gf/admin there are a few useful shell scripts for checking out
1615    and maintaining the entire collection of trees:
1616    
1617       admin/checkout-all.sh [dir]
1618          -- optionally creates dir and checks out all trees from their
1619             default repositories; if dir is missing, checkout into .
1620       admin/refresh-all.sh [dir]
1621          -- looks at all trees (from the above list) in dir (default: .)
1622             and runs "svn update" if the tree exists and is under
1623             subversion control;
1624             non-existing or non-subversion trees are skipped
1625       admin/stat-all.sh [dir]
1626          -- like refresh-all.sh, but runs "svn stat" instead

1645    I am freezing 110.59.  Changes other than the version-number increase:
1646    
1647      eXene:
1648    
1649         * committed changes to eXene from Alley Stoughton:
1650             "fixed bugs in X authorization and resource handling, as well
1651              as in the pile and viewport widgets"
1652    
1653      Runtime:
1654        * fixed linking problem with NetBSD 3.x.
1655    
1656      Lexgen:
1657        * lexgen tool handles non-ascii characters in 7-bit mode the same
1658          way that ml-lex does
1659    
1660        * lexgen propagates exceptions the same way that ml-lex does
1661    
1662      CML:
1663        * Fixed a bug in the SyncVar polling functions (iGetPoll,
1664          mTakePoll, and mGetPoll) that could lead to livelock.

1809    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
1810    at the time when config/preloads is processed, the library has to
1811    be referred to by another name.  In 110.57 this would be
1812    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
1813    to be valid as well.)

1868    Tag: blume-22051115-versiontool
1869    Description:
1870    
1871    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
1872    file gets loaded as a tool -- by the equivalent of CM.make during the
1873    run of CMB.make.  Thus, CMB's path configuration is meaningless for
1874    it.  Instead, it has the status of "user code", so it should use
1875    $/basis.cm to refer to the Basis library.  (At least that's true for
1876    the purpose of bootstrapping the previous change.  In the future it
1877    might make sense to have versiontool.cm refer to
1878    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
1879    compiler itself uses.)
1880    
1881    Also patched src/system/testml to have it activate those extra anchor
1882    bindings in config/extrapathconfig.

1887    Tag: blume-22051115-libraries
1888    Description:
1889    
1890    This change affects the way the following libraries are tied into
1891    the system:
1892    
1893       $/basis.cm
1894       $/smlnj-lib.cm
1895       $/pp-lib.cm
1896       $/controls-lib.cm
1897       $/html-lib.cm
1898       $/ml-yacc-lib.cm
1899    
1900    These libraries are now internally (as seen from the source code
1901    of the implementation itself) known by the following names:
1902    
1903       $smlnj/basis/basis.cm
1904       $smlnj/smlnj-lib/smlnj-lib.cm
1905       $smlnj/smlnj-lib/pp-lib.cm
1906       $smlnj/smlnj-lib/controls-lib.cm
1907       $smlnj/smlnj-lib/html-lib.cm
1908       $smlnj/ml-yacc/ml-yacc-lib.cm
1909    
1910    This makes it possible to work with code that requires different
1911    versions of these libraries, and which refers to these libraries using
1912    their "default" names (i.e., the first set of names above).  In other
1913    words, one can un-define or re-define those default names without
1914    compromising the proper functioning of the compiler itself.
1915    
1916    A similar procedure had already been performed for several of the
1917    MLRISC libraries that are linked into the compiler.  I did some
1918    cleanup on this code.
1919    
1920    A new file in the config directory (named extrapathconfig) is
1921    responsible for setting up path anchors that the compiler itself does
1922    not need, but that are typically required by user code.

2101    Tag: blume-20050516-redump-heap
2102    Description:
2103    
2104    Added mechanism for re-creating a heap file for the interactive system
2105    after configuration variables have been changed.
2106    
2107       CM.redump_heap : string -> unit
2108    
2109    This is much like SMLofNJ.exportML, but starting from the resulting
2110    heap does not return to the caller of CM.redump_heap but
2111    restarts the interactive system from scratch.  The original call of
2112    CM.redump_heap does not return but ends the interactive session.
2113    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
2114    
2115    Internally, redump_heap winds the dynamic execution context back to
2116    the point where the original heap image was created and re-executes
2117    the heap image generation code in the boot code.

2234    Description:
2235    
2236    Implemented new (but still experimental) heap2exec facility.  This is
2237    tested under Mac OS X and should work under Linux (will test shortly).
2238    It will probably also work on the Sparc (will test some time later).
2239    
2240      - removed old "HACKED_STANDALONE" hack from runtime
2241    
2242    To be able to test this, uncomment the request for "heap2asm" in
2243    config/targets prior to installation.  (Notice that this is different
2244    from "heap2exec" mentioned below.  Not a typo.)
2245    
2246    To perform an actual test, run the command
2247    
2248       $ bin/heap2exec heapfile execfile
2249    
2250    (You can put heap2exec on your shell's path.)
2251    
2252    For example, run
2253    
2254      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2255    
2256    This will create a standalone executable called "mly" which you can
2257    then invoke directly as a command.

2303    Description:
2304    
2305        The Unix I/O library of SML/NJ on cygwin does not understand
2306    Windows style pathname, so problems arise when SMLNJ_HOME is set
2307    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
2308    to a POSIX pathname on cygwin.

2402    Tag: blume-20041124-position
2403    Description:
2404    
2405    The compiler can now be compiled in a mode that makes structure Position
2406    equal to Int64.  The default, however, is unchanged (Position = Int31)
2407    for the time being.
2408    
2409    To enable 64-bit positions, use the following procedure:
2410    
2411    1. Start sml
2412    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
2413    3. Type
2414          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
2415    4. Run CMB.make() as usual.
2416    
2417    This is barely tested.  The only test so far was a little SML program
2418    counting the number of characters in an 8-gigabyte file by
2419    reading it character-by-character.  That test was successful.
2420    
2421    In support of 64-bit positions, a number of new functions have been
2422    added to the runtime system.

2464    
2465    - Stripped down the versiontool: It now only handles the version number.
2466      The date string is generated at bootstrap time (during makeml).
2467    
2468    - In a previous commit, fixed a minor issue with how polyequal is being
2469      translated.  In particular, the code now "looks through" abstractions.
2470      This results in slightly fewer polyEqual warnings and hopefully slightly
2471      more efficient code.  Important examples for where this matters are
2472      the new int64 and word64 types.

2489    All the pieces of Word64 are now there, with the exception of the
2490    conversions from and to LargeWord. (Eventually these need to be identities,
2491    but for the time being they don't even make sense because LargeWord is
2492    32-bit wide.)
2493    
2494    Also started to add similar support for Int64, but major pieces of that
2495    are still missing.

2501    Description:
2502    
2503    Structure Word64 is now (almost) complete, word literals and patterns
2504    seem to work.  There are a few odd pieces missing.  In particular,
2505    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
2506    at the moment.
2507    
2508    Making Word64 official would mean that LargeWord becomes Word64.  But
2509    this requires extreme care because most word-word conversions have to
2510    go through LargeWord, so making a mistake means loss of efficiency or
2511    worse.  Eventually there will be a solution similar to (but actually
2512    simpler than) what I did with IntInf.

2543    
2544      - Changend config/srcarchiveurl from a file just
2545        containing the URL string into a file containing
2546        shell script code.  The code has access to the $VERSION variable.
2547      - Made corresponding changes to config/install.sh and config/unpack.
2548      - Default contents of config/srcarchiveurl uses $VERSION and
2549        normally does not have to be edited to reflect a version change.
2550    
2551      (As a result, a version change can be done by just editing
2552       config/version, the rest is now automatic.)

2573      - made sure the caller does not add the wrong number of bytes to the
2574        stack pointer after a call of a function returning a struct
2575        (the callee already pops the implicit argument which points to
2576         the space reserved for the result)

2592    Tag: blume-20041020-standalone-backtrace
2593    Description:
2594    
2595    Added a mechanism for getting back-trace information from standalone
2596    programs.  Here is how it works:
2597    
2598       1. The part of the program from which you want to get backtrace
2599          information (usually the whole program) should be wrapped with
2600          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
2601          main program could be modified from something like
2602    
2603             fun main (pgm, args) = ...
2604    
2605         to
2606    
2607            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
2608    
2609       2. To be able to access BackTrace.monitor, you have to add
2610          library $smlnj-tdp/plugins.cm to the .cm file that contains your
2611          main function.
2612    
2613       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
2614          CM might have created in the past for your project).
2615    
2616       4. Build the system using this command line:
2617    
2618             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
2619                      myprog.cm MyProg.main myprog
2620    
2621          instead of the usual
2622    
2623             ml-build myprog.cm MyProg.main myprog
2624    
2625    I changed a library name:
2626    
2627       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
2628    
2629    New libraries:
2630    
2631       $smlnj-tdp/back-trace.cm
2632          -- when loaded causes the back-trace plugin to be installed
2633       $smlnj-tdp/coverage.cm
2634          -- when loaded causes the coverage plugin to be installed

2650    Description:
2651    
2652    * Test coverage tool added!
2653    * Further reorganization of tracing-, debugging-, and profiling support:
2654    
2655        - moved original BTImp -- now called BackTrace -- into a separate
2656          library called $/trace-debug-profile.cm
2657        - eliminated all mentions of BTrace from SMLofNJ.Internals
2658        - only the instrumentation mechanism is now left in the compiler proper
2659        - BackTrace module is a plugin which is NOT plugged in by default
2660        - Coverage module is another such plugin
2661    
2662    To get the benefits of any of these plugin modules, the code in
2663    question must be compiled with tdp instrumentation turned on.  This
2664    can be done by setting SMLofNJ.Internals.TDP.mode to true.
2665    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
2666    
2667    Plugins are selected at link time.  (Pre-compiled instrumented code
2668    can be re-loaded with different plugins in effect.)  When an
2669    instrumented module is linked, whatever plugins are at that time
2670    enabled will come into effect for that module.
2671    
2672    To enable the back-trace plugin, load library $/trace-debug-profile.cm
2673    and invoke BackTrace.install() (e.g., from the interactive prompt).
2674    To enable the coverage plugin, load the same library and invoke
2675    Coverage.install().
2676    
2677    Back-traces are generated automatically on uncaught exceptions and
2678    when the code in question explicitly invokes BackTrace.trigger().
2679    
2680    Coverage (and execution frequency-) information must be queried
2681    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

2704    instrumentation for other purposes.  "TDP" stands for

2706    
2707    The control flag controlling whether instrumentation is on or off is now
2708    registered under a different name, so instead of running sml as
2709    
2710     sml -Cinstrument.btrace-mode=true

2736    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
2737    is supposed to accept a tool argument called "source", but this did
2738    not work because of the clash with the keyword.

2781    Description:
2782    
2783    * Moved the "version" magic into its own little library under
2784      src/system/smlnj/internal.  This avoids expensive reconstruction of
2785      a stable src/compiler/core.cm.
2786    
2787    * At the same time, structure CompilerVersion is now known as
2788      structure SMLNJVersion.
2789    
2790    * Arranged for the version tool to NOT kick in when rebuilding the system
2791      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
2792      Also, loading the versiontool does not work when rebuilding the system
2793      because CM is not properly initialized at that time.

2798    Tag: blume-20040929-autoversion
2799    Description:
2800    
2801    Implemented some CM magic to have
2802        file src/compiler/TopLevel/main/version.sml
2803    generated automagically.
2804    The version is taken from two files: config/version and config/release.
2805    The first is expected to contain a two-part version number such as 110.49.
2806    The second should contain a single number, but it may be missing.
2807    
2808    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
2809    time the version tool is loaded (which is the first time you say CMB.make),
2810    then the tool will increment the value stored in config/release every
2811    time CMB.make is invoked.
2812    
2813    The binfile format is now insensitive to anything beyond the first
2814    two components of a version number, so bumping the release does not render
2815    binfiles incompatible.  Auto-bumping can be used to keep track of versions
2816    during development without invalidating existing binfiles.
2817    
2818    In any case, every CMB.make updates the date information in version.sml.
2819    (This is the date that is printed in the banner.)

2832    Tag: blume-20040927-controls
2833    Description:
2834    
2835    Added two pieces of functionality to the Controls interface:
2836    
2837    1.   val save'restore: 'a control -> unit -> unit
2838    
2839       grabs the current value of the control in stage 1 and restores it
2840       in stage 2.
2841    
2842    2.   val set' : 'a control * 'a -> unit -> unit
2843    
2844       stores the given value into the control in stage 2 (i.e., delayed)
2845       but does all error checking in stage 1.
2846       (This is for string controls that need to do parse their argument --
2847        something that might fail.  In some cases, notably in CM, one
2848        already knows the intended argument but wants to delay the actual
2849        assignment until a time when error recovery would be more difficult.)
2850    
2851    Changed the handling of controls in tool arguments to classes "sml" and
2852    "lazysml":
2853       - use Controls.save'restore as a more robust way of restoring the
2854         old value (in particular: without having to re-parse the string)
2855       - use controls to handle the "overload" keyword in the init group
2856         (I believe this change actually fixes a long-standing obscure bug.)

2861    Tag: blume-20040927-lazysml
2862    Description:
2863    
2864    Added a new tool class called "lazysml" to CM's tool chest.  The only
2865    difference to "sml" is that compilation is done with Control.lazysml
2866    set to true.  A source of class "lazysml" is automatically recognized
2867    by a file name suffix of ".lml".
2868    
2869    In addition to the above feature, the original class "sml" now also
2870    supports a tool argument "lazy" which has the same effect.  As a
2871    result, the following three lines are equivalent:
2872    
2873        foo.sml : lazysml
2874        foo.sml : sml (lazy)
2875        foo.sml (lazy)
2876    
2877    The setting goes into effect both during parsing and during
2878    compilation.  The original setting is restored right after parsing and
2879    after compilation, respectively.
2880    
2881    In addition to all the above, there is also a general mechanism to set
2882    ANY of the "controls" that are available at the command line via
2883    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
2884    apply as well. (In fact, "lazy" is implemented as a special case of
2885    the general mechanism.)
2886    
2887    The .cm file syntax uses a new keyword tool argument called "with".
2888    There are several ways of indicating the desired settings:
2889    
2890        foo.sml (with:parser.quotations=true)
2891        foo.sml (with:(name:parser.quotations value:true))
2892        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
2893        foo.sml (with:(name1=value1 name2=value2 ...))
2894        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
2895    
2896        etc.
2897    
2898    Another possible abbreviation is to leave out the =v or value:v part
2899    if the name refers to a boolean control (in which case the value is
2900    taken to be true).  Thus, one could get lazy sml also by saying:
2901    
2902        foo.sml (with:parser.lazy-keyword=true)
2903        foo.sml (with:parser.lazy-keyword)
2904        foo.sml (with:(name:parser.lazy-keyword value:true))
2905        foo.sml (with:(name:parser.lazy-keyword))

3163    Description:
3164    
3165    Added C_UNION to c-calls/c-types.sml and updated the machinery
3166    (ml-nlffigen, cproto.sml) that conveys C function interface
3167    information to the code generator.
3168    
3169    However, the actual architecture-specific implementation of function
3170    arguments and results that are C unions is still not implemented.

3203    
3204    - use paramAlloc to report c-calls with too many arguments
3205      (for PPC version where parameter area is pre-allocated)
3206    - added ccall_maxargspace to machspec (to implement the above)
3207    - made "make" commend in CM's "make" tool configurable
3208    - added option (default: on) for passing the name of the SML/NJ's "bin"
3209      directory to "make"; the call looks like this:
3210    
3211         make <options> SMLNJ_BINDIR=<dir> <target>
3212    
3213      This can be used by the Makefile to, e.g., pick the "right" version
3214      of ml-nlffigen.

3223    NLFFI under Mac OS X now working (sort of).  This is largely untested,
3224    though.
3225    
3226    Note:  1. You have to make a new, clean build of the runtime system.
3227           2. There are new BOOTFILES, you have to use them!
3228              (Doing the bootstrap process yourself would be *very* painful!
3229               If you absolutely have to do it, build the system under
3230               a different architecture and then cross-compile.)
3231    
3232    Version bumped to 110.46.1 to account for runtime data format changes.

3257    Description:
3258    
3259    Changed the interface of structures Timer and Unix to match the most
3260    recent Basis spec.
3261    
3262    In the case of Unix there still seems to be an open/weird issue:
3263    
3264       The {text,bin}{In,Out}streamOf functions are supposed to create
3265       fresh streams whenever they are called -- as opposed to have them
3266       return the same stream every time.  This design is supposed to
3267       prevent space leaks caused by proc values hanging on to streams.
3268    
3269       The reap function, on the other hand, is supposed to close the
3270       streams.  This cannot be done without having a handle on the
3271       stream in proc after all...
3272    
3273    I took the liberty to implement the following stopgap solution:
3274    
3275      The proc value hangs on to the most recently created stream(s).
3276      Reap closes those.  If either or both of the two streams hadn't
3277      been created at all yet, then reap will close the corresponding
3278      file descriptors directly.
3279    
3280    PS: I don't understand the original space leak argument anymore.  If
3281    a proc hangs on to the imperative stream, then I/O operations on those
3282    will advance the state of the cached stream and avoid the space leak.

3295    Tag: blume-20040525-group-owner
3296    Description:
3297    
3298    CM now ignores (but still accepts) the "owner" information in group
3299    descriptions.  The owner of a group is its next enclosing
3300    library. Each group must have a unique owner.  (There is a virtual
3301    "toplevel" library that owns groups which are not nested within a real
3302    library.)  Previously, each group had to explicitly declare its owner,
3303    and CM would check that such a declaration is correct.  The new scheme
3304    is to have CM check that for each group there is precisely one owning
3305    library.
3306    
3307    The advantage of the new scheme is that the programmer no longer needs
3308    to maintain the somewhat annoying owner information.  The downside is
3309    that CM cannot enforce the ownership rule across multiple runs of
3310    CM.make.  Fortunately, enclosing the same group in two different
3311    libraries A and B which are not part of the same program does not
3312    cause real problems.

3324    Also, included a minor addition to ml-build.bat analogous to what was
3325    done in blume-20040519-ml-build.

3331    Description:
3332    
3333    Arranged for ml-build to clean up after itself a little bit better.
3334    The script generates a temporary SML source file and compiles it using
3335    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
3336    gets rid of those at the end, so they don't accumulate under .cm.
3337    
3338    This required a minor change to install.sh because the name of the
3339    metadata directory (default: .cm) is actually configurable at
3340    installation time.

3355    Description:
3356    
3357    Added previously missing support for many socket-related functions
3358    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
3359    for the voluminous patch!
3360    
3361    (I have not tested this patch under win32 yet.)
3362    
3363    Here is David's e-mail:
3364    
3365    Hi,
3366    
3367    Attached to this email you find a diff against sml/nj 110.45
3368    that will enable socket support under Windows.
3369    
3370    To apply the patch (using unix or cygwin)
3371    1) gunzip runtime.diff.gz
3372    2) "cd" into "src/runtime" in the source tree of a fresh
3373       110.45 installation.
3374    3) patch -p 1 < [your/path/to]runtime.diff
3375    
3376    The code compiles fine but has NOT yet been extensively tested.
3377    I only ran a few tests for basic socket client functionality
3378    (which worked fine).  Especially the functions that use ioctl
3379    are not tested at all and might not work (see below).
3380    
3381    I implemented this since we want to move to a newer version of sml/nj
3382    but need socket support in order to use it.  This is the first time I
3383    even had a look at the sml/nj source,  so please review my changes
3384    before making this part of the distribution!  Here are a few issues
3385    that I think might be better for someone to solve who is more
3386    familiar with the sml/nj source (and socket programming):
3387    
3388    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3389      exception since I could not figure out what the windows equivalent
3390      of these functions is
3391    
3392    - In sockets-osdep.h there are a some #include statements that are
3393      only used in a few files that include sockets-osdep.h
3394    
3395    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3396      does not process its return value since I don't know how to
3397      report an error upwards.
3398    
3399    - It would probably be good to have a call to WSACleanup() when
3400      the library is unloaded (if there is such a possibility).
3401      Otherwise I think Windows will take care of this automatically
3402      when the process finishes.
3403    
3404    - I used ioctlsocket() as a replacement for ioctl() but I have
3405      no idea if that is actually the proper replacement on Windows.
3406    
3407    - All these issues are marked in the code by "FIXME" comments.
3408    
3409    We use sml/nj extensively in our products and are quite happy
3410    with it.  I hope this contribution will help you.
3411    
3412    Keep up the good work!
3413

3452    in the "targets" file, then the installer will pull in sources for
3453    everything.  (Notice that this refers to source code only.  Compiled
3454    code is still only installed for modules that were requested explicitly
3455    or which are required for other modules that were requested explicitly.)

3491    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version

3493    
3494       lib = dlopen(NULL, ...)
3495       f   = dlsym(lib, "malloc");
3496    
3497    does not work on Windows unless we explicitly export symbols
3498    such as 'malloc' during linking.  We fixed this by explicitly
3499    exporting the required symbols with the magic gcc incantation:
3500    
3501        -Wl,--export-all cygwin.def
3502    
3503    where cygwin.def is a file containing all the symbols that
3504    we wish to export.
3505    
3506    I suspect this is a Windows problem and we'll have to
3507    do the same (somehow with windows compilers) when
3508    we build the native win32 version with the system
3509    calls LoadLibrary/GetProcAddress.
