19    Description:
20    
21    Brought ml-lpt manual up-to-date with the code.  Many minor
22    improvements to the tools, and a few minor bugfixes.  Prepared
23    ml-lpt-lib for integration with new UTF8 structure.  Changed
24    the interface for creating streams in ml-ulex (we now support
25    stream creation from several kinds of sources).  Overall, the
26    tools are now quite stable, and their interfaces are unlikely to
27    change in a way that would break compatibility.  More work,
28    however, is needed in the documentation.

33    Description:
34    
35    Added SMLofNJ.shiftArgs which is like a shell's "shift" command.
36    Modified CM's startup code to use shiftArgs as it processes
37    command line arguments.  This way, the init code in each .sml-file
38    or library that is mentioned at the top level will see only
39    those arguments that have not yet been processed at this point.
40    In other words, the init code can "seize control" and process the
41    remaining command line.

48    Added the UTF8 structure and signature from the Moby compiler to
49    the SML/NJ library (and the CML library).  These modules will replace
50    the version in the ml-lpt-lib.

99    Date: 2006/12/08 09:50:00 CST
100    Description:
101    
102    Added code to CM's "standard shell tool" implementation which
103    causes it to tolerate (with a warning) the situation where the shell
104    command fails (e.g., due to the shell command's non-existence)
105    as long as all target files exist.
106    
107    This makes it possible to, e.g., build ml-yacc from sources even if
108    svn checkout messed up the time stamps on files in such a way that
109    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
110    be needed to re-process yacc.grm, but obviously it might not yet be
111    available at that time.)

151    Description:
152    
153    New working release (110.60).  NEW BOOTFILES!
154    
155    This is the first subversion-hosted release.  There are also changes
156    to the directory layout.  Here is a table:
157    
158    (All pathnames are relative to the SML/NJ "root" directory.)
159    
160      config -> config
161    
162      src/cm -> base/cm
163      src/compiler -> base/compiler
164      src/runtime -> base/runtime
165      src/system -> base/system
166    
167      src/cm/pgraph -> pgraph
168    
169      src/READMES -> base/READMES
170      src/$notefile -> base/NOTES/$notefile
171         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
172                           MACOSXINSTALL WININSTALL
173    
174      src/smlnj-lib -> smlnj-lib
175      src/MLRISC -> MLRISC
176      ckit -> ckit
177      src/cml -> cml
178      src/eXene -> eXene
179      src/heap2asm -> heap2asm
180      src/lexgen -> lexgen
181      src/ml-burg -> ml-burg
182      src/ml-lex -> ml-lex
183      src/ml-yacc -> ml-yacc
184      src/ml-nlffi-lib -> nlffi/lib
185      src/ml-nlffigen -> nlffi/gen
186      src/smlnj-c -> smlnj-c
187      src/tools/TraceDebugProf -> trace-debug-profile
188    
189    In addition, there is also a new
190    
191      ml-lpt
192    
193    directory containing two new program generator tools: ml-ulex and
194    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
195    LL(k) parser generator). These tools are currently "beta-quality"
196    
197    The latest versios of the sources can now be obtained anonymously
198    via subversion.  For this, it is useful to first check out
199    
200       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
201    
202    and put the resulting directory on your shell's PATH.  This provides
203    access to three shell scripts: checkout-all.sh, stat-all.sh,
204    and refresh-all.sh.
205    
206    To create a freshly checked-out copy of the sources, do
207    
208       checkout-all.sh [dir]
209    
210    where dir is the optional SML/NJ root directory (default is ".").
211    
212    This creates the above directory layout.  Each subdirectory of
213    the root is under individual subversion control.  The stat-all.sh
214    and refresh-al.sh scripts apply "svn stat" or "svn update" to
215    each of these subtrees.
216    
217    ----------------------------------------------------------------------
218    Name: Matthias Blume (http://www.tti-c.org/blume/)
219    Date: 2006/11/02 12:20:00 CST
220    Description:
221    
222    Reorganized directory layout.
223    
224    This is a temporary solution, more reorganization is to come.
225    
226    The basic idea is to have a number of toplevel trees, each corresponding
227    to a well-defined part of the overall system.  Each part can be
228    maintained individually, even in separate source repositories,
229    although currently we still serve everything out of the main
230    smlnj-gforge tree.
231    
232    Installer and and scripts have been updated to reflect the new
233    layout.  The installer (base/src/system/smlnj/installer) is now
234    "scriptable" to avoid burning too much knowledge about the
235    layout into SML source code.  The main script used by the installer
236    is in config/actions.
237    
238    The main change is that many of the subdirectories of what used to
239    be known as "src" have moved to the toplevel.  The "src" directory
240    itself has moved down into a subtree called "base".  (We may eventually
241    get rid of the extra level of indirection represented by "src".)
242    
243    The layout is now as follows:
244    
245      toplevel tree name | default repository
246                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
247      -------------------+----------------------------------------------------
248      config             | $gf/config/trunk
249                         |
250      base               | $gf/sml/trunk
251                         |
252      smlnj-lib          | $gf/smlnj-lib/trunk
253      MLRISC             | $gf/MLRISC/trunk
254                         |
255      ml-yacc            | $gf/ml-yacc/trunk
256      ml-lex             | $gf/ml-lex/trunk
257      ml-burg            | $gf/ml-burg/trunk
258      lexgen             | $gf/lexgen/trunk
259      heap2asm           | $gf/heap2asm/trunk
260                         |
261      cml                | $gf/cml/trunk
262      eXene              | $gf/eXene/trunk
263      ckit               | $gf/ckit/trunk
264      nlffi              | $gf/nlffi/trunk
265                         |
266      smlnj-c            | $gf/smlnj-c/trunk
267    
268    In $gf/admin there are a few useful shell scripts for checking out
269    and maintaining the entire collection of trees:
270    
271       admin/checkout-all.sh [dir]
272          -- optionally creates dir and checks out all trees from their
273             default repositories; if dir is missing, checkout into .
274       admin/refresh-all.sh [dir]
275          -- looks at all trees (from the above list) in dir (default: .)
276             and runs "svn update" if the tree exists and is under
277             subversion control;
278             non-existing or non-subversion trees are skipped
279       admin/stat-all.sh [dir]
280          -- like refresh-all.sh, but runs "svn stat" instead

297    New working version (110.59).  NEW BOOTFILES!
298    
299    I am freezing 110.59.  Changes other than the version-number increase:
300    
301      eXene:
302    
303         * committed changes to eXene from Alley Stoughton:
304             "fixed bugs in X authorization and resource handling, as well
305              as in the pile and viewport widgets"
306    
307      Runtime:
308        * fixed linking problem with NetBSD 3.x.
309    
310      Lexgen:
311        * lexgen tool handles non-ascii characters in 7-bit mode the same
312          way that ml-lex does
313    
314        * lexgen propagates exceptions the same way that ml-lex does
315    
316      CML:
317        * Fixed a bug in the SyncVar polling functions (iGetPoll,
318          mTakePoll, and mGetPoll) that could lead to livelock.

460    Description:
461    
462    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
463    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
464    at the time when config/preloads is processed, the library has to
465    be referred to by another name.  In 110.57 this would be
466    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
467    to be valid as well.)
468    
469    Thanks to Todd Wilson (Fresno) for alerting me to this issue.

485    Fixed a problem in config/install.sh where it tries to "fish" the
486    name of the CM metadata directory from the wrong place (because
487    the physical location of basis.cm has changed).  Also, corrected the
488    path anchor for $/html-lib.cm.  (Thanks to M. Fluet for pointing out
489    these problems.)

522    Tag: blume-22051115-versiontool
523    Description:
524    
525    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
526    file gets loaded as a tool -- by the equivalent of CM.make during the
527    run of CMB.make.  Thus, CMB's path configuration is meaningless for
528    it.  Instead, it has the status of "user code", so it should use
529    $/basis.cm to refer to the Basis library.  (At least that's true for
530    the purpose of bootstrapping the previous change.  In the future it
531    might make sense to have versiontool.cm refer to
532    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
533    compiler itself uses.)
534    
535    Also patched src/system/testml to have it activate those extra anchor
536    bindings in config/extrapathconfig.

541    Tag: blume-22051115-libraries
542    Description:
543    
544    This change affects the way the following libraries are tied into
545    the system:
546    
547       $/basis.cm
548       $/smlnj-lib.cm
549       $/pp-lib.cm
550       $/controls-lib.cm
551       $/html-lib.cm
552       $/ml-yacc-lib.cm
553    
554    These libraries are now internally (as seen from the source code
555    of the implementation itself) known by the following names:
556    
557       $smlnj/basis/basis.cm
558       $smlnj/smlnj-lib/smlnj-lib.cm
559       $smlnj/smlnj-lib/pp-lib.cm
560       $smlnj/smlnj-lib/controls-lib.cm
561       $smlnj/smlnj-lib/html-lib.cm
562       $smlnj/ml-yacc/ml-yacc-lib.cm
563    
564    This makes it possible to work with code that requires different
565    versions of these libraries, and which refers to these libraries using
566    their "default" names (i.e., the first set of names above).  In other
567    words, one can un-define or re-define those default names without
568    compromising the proper functioning of the compiler itself.
569    
570    A similar procedure had already been performed for several of the
571    MLRISC libraries that are linked into the compiler.  I did some
572    cleanup on this code.
573    
574    A new file in the config directory (named extrapathconfig) is
575    responsible for setting up path anchors that the compiler itself does
576    not need, but that are typically required by user code.

755    Tag: blume-20050516-redump-heap
756    Description:
757    
758    Added mechanism for re-creating a heap file for the interactive system
759    after configuration variables have been changed.
760    
761       CM.redump_heap : string -> unit
762    
763    This is much like SMLofNJ.exportML, but starting from the resulting
764    heap does not return to the caller of CM.redump_heap but
765    restarts the interactive system from scratch.  The original call of
766    CM.redump_heap does not return but ends the interactive session.
767    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
768    
769    Internally, redump_heap winds the dynamic execution context back to
770    the point where the original heap image was created and re-executes
771    the heap image generation code in the boot code.

887    Tag: blume-20050114-heap2exec
888    Description:
889    
890    Implemented new (but still experimental) heap2exec facility.  This is
891    tested under Mac OS X and should work under Linux (will test shortly).
892    It will probably also work on the Sparc (will test some time later).
893    
894      - removed old "HACKED_STANDALONE" hack from runtime
895    
896    To be able to test this, uncomment the request for "heap2asm" in
897    config/targets prior to installation.  (Notice that this is different
898    from "heap2exec" mentioned below.  Not a typo.)
899    
900    To perform an actual test, run the command
901    
902       $ bin/heap2exec heapfile execfile
903    
904    (You can put heap2exec on your shell's path.)
905    
906    For example, run
907    
908      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
909    
910    This will create a standalone executable called "mly" which you can
911    then invoke directly as a command.

936    (The parameter-passing part of the picture has not complete. But

938    
939    * Fixed CM's incorrect assumption that the PPC is little-endian.
940      (On the Mac, it is big-endian.  And that's currently our only
941      PPC platform.)

958    
959        The Unix I/O library of SML/NJ on cygwin does not understand
960    Windows style pathname, so problems arise when SMLNJ_HOME is set
961    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
962    to a POSIX pathname on cygwin.

1056    Tag: blume-20041124-position
1057    Description:
1058    
1059    The compiler can now be compiled in a mode that makes structure Position
1060    equal to Int64.  The default, however, is unchanged (Position = Int31)
1061    for the time being.
1062    
1063    To enable 64-bit positions, use the following procedure:
1064    
1065    1. Start sml
1066    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
1067    3. Type
1068          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
1069    4. Run CMB.make() as usual.
1070    
1071    This is barely tested.  The only test so far was a little SML program
1072    counting the number of characters in an 8-gigabyte file by
1073    reading it character-by-character.  That test was successful.
1074    
1075    In support of 64-bit positions, a number of new functions have been
1076    added to the runtime system.

1121    
1122    - In a previous commit, fixed a minor issue with how polyequal is being
1123      translated.  In particular, the code now "looks through" abstractions.
1124      This results in slightly fewer polyEqual warnings and hopefully slightly
1125      more efficient code.  Important examples for where this matters are
1126      the new int64 and word64 types.

1146    32-bit wide.)
1147    
1148    Also started to add similar support for Int64, but major pieces of that
1149    are still missing.

1155    Description:
1156    
1157    Structure Word64 is now (almost) complete, word literals and patterns
1158    seem to work.  There are a few odd pieces missing.  In particular,
1159    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1160    at the moment.
1161    
1162    Making Word64 official would mean that LargeWord becomes Word64.  But
1163    this requires extreme care because most word-word conversions have to
1164    go through LargeWord, so making a mistake means loss of efficiency or
1165    worse.  Eventually there will be a solution similar to (but actually
1166    simpler than) what I did with IntInf.

1199        containing the URL string into a file containing
1200        shell script code.  The code has access to the $VERSION variable.
1201      - Made corresponding changes to config/install.sh and config/unpack.
1202      - Default contents of config/srcarchiveurl uses $VERSION and
1203        normally does not have to be edited to reflect a version change.
1204    
1205      (As a result, a version change can be done by just editing
1206       config/version, the rest is now automatic.)

1246    Tag: blume-20041020-standalone-backtrace
1247    Description:
1248    
1249    Added a mechanism for getting back-trace information from standalone
1250    programs.  Here is how it works:
1251    
1252       1. The part of the program from which you want to get backtrace
1253          information (usually the whole program) should be wrapped with
1254          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1255          main program could be modified from something like
1256    
1257             fun main (pgm, args) = ...
1258    
1259         to
1260    
1261            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1262    
1263       2. To be able to access BackTrace.monitor, you have to add
1264          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1265          main function.
1266    
1267       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1268          CM might have created in the past for your project).
1269    
1270       4. Build the system using this command line:
1271    
1272             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1273                      myprog.cm MyProg.main myprog
1274    
1275          instead of the usual
1276    
1277             ml-build myprog.cm MyProg.main myprog
1278    
1279    I changed a library name:
1280    
1281       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1282    
1283    New libraries:
1284    
1285       $smlnj-tdp/back-trace.cm
1286          -- when loaded causes the back-trace plugin to be installed
1287       $smlnj-tdp/coverage.cm
1288          -- when loaded causes the coverage plugin to be installed

1304    Description:
1305    
1306    * Test coverage tool added!
1307    * Further reorganization of tracing-, debugging-, and profiling support:
1308    
1309        - moved original BTImp -- now called BackTrace -- into a separate
1310          library called $/trace-debug-profile.cm
1311        - eliminated all mentions of BTrace from SMLofNJ.Internals
1312        - only the instrumentation mechanism is now left in the compiler proper
1313        - BackTrace module is a plugin which is NOT plugged in by default
1314        - Coverage module is another such plugin
1315    
1316    To get the benefits of any of these plugin modules, the code in
1317    question must be compiled with tdp instrumentation turned on.  This
1318    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1319    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1320    
1321    Plugins are selected at link time.  (Pre-compiled instrumented code
1322    can be re-loaded with different plugins in effect.)  When an
1323    instrumented module is linked, whatever plugins are at that time
1324    enabled will come into effect for that module.
1325    
1326    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1327    and invoke BackTrace.install() (e.g., from the interactive prompt).
1328    To enable the coverage plugin, load the same library and invoke
1329    Coverage.install().
1330    
1331    Back-traces are generated automatically on uncaught exceptions and
1332    when the code in question explicitly invokes BackTrace.trigger().
1333    
1334    Coverage (and execution frequency-) information must be queried
1335    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1359    Trace/Debug/Profile.
1360    
1361    The control flag controlling whether instrumentation is on or off is now
1362    registered under a different name, so instead of running sml as
1363    
1364     sml -Cinstrument.btrace-mode=true
1365    
1366    one has to say
1367    
1368     sml -Ctdp.instrument=true

1384    Description:
1385    
1386    Fixed handling of keywords in .cm files: After seeing "is" the lexer
1387    treats subsequent occurrences of "group", "library", "source", "is",
1388    "*", and "-" as ordinary identifiers rather than keywords.
1389    
1390    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1391    is supposed to accept a tool argument called "source", but this did
1392    not work because of the clash with the keyword.

1435    Description:
1436    
1437    * Moved the "version" magic into its own little library under
1438      src/system/smlnj/internal.  This avoids expensive reconstruction of
1439      a stable src/compiler/core.cm.
1440    
1441    * At the same time, structure CompilerVersion is now known as
1442      structure SMLNJVersion.
1443    
1444    * Arranged for the version tool to NOT kick in when rebuilding the system
1445      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
1446      Also, loading the versiontool does not work when rebuilding the system
1447      because CM is not properly initialized at that time.

1452    Tag: blume-20040929-autoversion
1453    Description:
1454    
1455    Implemented some CM magic to have
1456        file src/compiler/TopLevel/main/version.sml
1457    generated automagically.
1458    The version is taken from two files: config/version and config/release.
1459    The first is expected to contain a two-part version number such as 110.49.
1460    The second should contain a single number, but it may be missing.
1461    
1462    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1463    time the version tool is loaded (which is the first time you say CMB.make),
1464    then the tool will increment the value stored in config/release every
1465    time CMB.make is invoked.
1466    
1467    The binfile format is now insensitive to anything beyond the first
1468    two components of a version number, so bumping the release does not render
1469    binfiles incompatible.  Auto-bumping can be used to keep track of versions
1470    during development without invalidating existing binfiles.
1471    
1472    In any case, every CMB.make updates the date information in version.sml.
1473    (This is the date that is printed in the banner.)

1486    Tag: blume-20040927-controls
1487    Description:
1488    
1489    Added two pieces of functionality to the Controls interface:
1490    
1491    1.   val save'restore: 'a control -> unit -> unit
1492    
1493       grabs the current value of the control in stage 1 and restores it
1494       in stage 2.
1495    
1496    2.   val set' : 'a control * 'a -> unit -> unit
1497    
1498       stores the given value into the control in stage 2 (i.e., delayed)
1499       but does all error checking in stage 1.
1500       (This is for string controls that need to do parse their argument --
1501        something that might fail.  In some cases, notably in CM, one
1502        already knows the intended argument but wants to delay the actual
1503        assignment until a time when error recovery would be more difficult.)
1504    
1505    Changed the handling of controls in tool arguments to classes "sml" and
1506    "lazysml":
1507       - use Controls.save'restore as a more robust way of restoring the
1508         old value (in particular: without having to re-parse the string)
1509       - use controls to handle the "overload" keyword in the init group
1510         (I believe this change actually fixes a long-standing obscure bug.)

1515    Tag: blume-20040927-lazysml
1516    Description:
1517    
1518    Added a new tool class called "lazysml" to CM's tool chest.  The only
1519    difference to "sml" is that compilation is done with Control.lazysml
1520    set to true.  A source of class "lazysml" is automatically recognized
1521    by a file name suffix of ".lml".
1522    
1523    In addition to the above feature, the original class "sml" now also
1524    supports a tool argument "lazy" which has the same effect.  As a
1525    result, the following three lines are equivalent:
1526    
1527        foo.sml : lazysml
1528        foo.sml : sml (lazy)
1529        foo.sml (lazy)
1530    
1531    The setting goes into effect both during parsing and during
1532    compilation.  The original setting is restored right after parsing and
1533    after compilation, respectively.
1534    
1535    In addition to all the above, there is also a general mechanism to set
1536    ANY of the "controls" that are available at the command line via
1537    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
1538    apply as well. (In fact, "lazy" is implemented as a special case of
1539    the general mechanism.)
1540    
1541    The .cm file syntax uses a new keyword tool argument called "with".
1542    There are several ways of indicating the desired settings:
1543    
1544        foo.sml (with:parser.quotations=true)
1545        foo.sml (with:(name:parser.quotations value:true))
1546        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
1547        foo.sml (with:(name1=value1 name2=value2 ...))
1548        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
1549    
1550        etc.
1551    
1552    Another possible abbreviation is to leave out the =v or value:v part
1553    if the name refers to a boolean control (in which case the value is
1554    taken to be true).  Thus, one could get lazy sml also by saying:
1555    
1556        foo.sml (with:parser.lazy-keyword=true)
1557        foo.sml (with:parser.lazy-keyword)
1558        foo.sml (with:(name:parser.lazy-keyword value:true))
1559        foo.sml (with:(name:parser.lazy-keyword))

1785    Description:
1786    
1787    Gearing up towards 110.47...
1788    
1789    - various minor bugfixes to ml-nlffigen
1790    - a beginning of a manual for nlffi
1791    
1792    - eliminated 'export name=value' in config/install.sh as this does
1793      not work with certain versions of /bin/sh
1794      (Thanks to David King at Motorola for catching this.)
1795    
1796    - several bugfixes provided or suggested by David Hansel at Reactive Systems:
1797      - added a test for tm==NULL to gmtime.c and localtime.c
1798      - applied patch for incorrect GetFileTime under win32
1799      - toSeconds -> toMilliseconds in Win32/win32-process.sml

1805    Description:
1806    
1807    - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
1808      for a typedef to an incomplete type, but leave out the "typ" member.
1809      (This is just for consistency.)
1810    - Started to produce what is supposed to become better (i.e., comprehensive)
1811      documentation of what ml-nlffigen does and produces.

1817    Description:
1818    
1819    Added C_UNION to c-calls/c-types.sml and updated the machinery
1820    (ml-nlffigen, cproto.sml) that conveys C function interface
1821    information to the code generator.
1822    
1823    However, the actual architecture-specific implementation of function
1824    arguments and results that are C unions is still not implemented.
