19    Description:
20    
21    Added code to CM's "standard shell tool" implementation which
22    causes it to tolerate (with a warning) the situation where the shell
23    command fails (e.g., due to the shell command's non-existence)
24    as long as all target files exist.
25    
26    This makes it possible to, e.g., build ml-yacc from sources even if
27    svn checkout messed up the time stamps on files in such a way that
28    yacc.grm is younger than yacc.grm.sml or yacc.grm.sig.  (Ml-yacc would
29    be needed to re-process yacc.grm, but obviously it might not yet be
30    available at that time.)

70    Description:
71    
72    New working release (110.60).  NEW BOOTFILES!
73    
74    This is the first subversion-hosted release.  There are also changes
75    to the directory layout.  Here is a table:
76    
77    (All pathnames are relative to the SML/NJ "root" directory.)
78    
79      config -> config
80    
81      src/cm -> base/cm
82      src/compiler -> base/compiler
83      src/runtime -> base/runtime
84      src/system -> base/system
85    
86      src/cm/pgraph -> pgraph
87    
88      src/READMES -> base/READMES
89      src/$notefile -> base/NOTES/$notefile
90         for <notefile> in BOOT CVSNOTES CYGWININSTALL HISTORY INSTALL
91                           MACOSXINSTALL WININSTALL
92    
93      src/smlnj-lib -> smlnj-lib
94      src/MLRISC -> MLRISC
95      ckit -> ckit
96      src/cml -> cml
97      src/eXene -> eXene
98      src/heap2asm -> heap2asm
99      src/lexgen -> lexgen
100      src/ml-burg -> ml-burg
101      src/ml-lex -> ml-lex
102      src/ml-yacc -> ml-yacc
103      src/ml-nlffi-lib -> nlffi/lib
104      src/ml-nlffigen -> nlffi/gen
105      src/smlnj-c -> smlnj-c
106      src/tools/TraceDebugProf -> trace-debug-profile
107    
108    In addition, there is also a new
109    
110      ml-lpt
111    
112    directory containing two new program generator tools: ml-ulex and
113    ml-antlr (a lexer generator that handles unicode and an ANTRL-inspired
114    LL(k) parser generator). These tools are currently "beta-quality"
115    
116    The latest versios of the sources can now be obtained anonymously
117    via subversion.  For this, it is useful to first check out
118    
119       svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
120    
121    and put the resulting directory on your shell's PATH.  This provides
122    access to three shell scripts: checkout-all.sh, stat-all.sh,
123    and refresh-all.sh.
124    
125    To create a freshly checked-out copy of the sources, do
126    
127       checkout-all.sh [dir]
128    
129    where dir is the optional SML/NJ root directory (default is ".").
130    
131    This creates the above directory layout.  Each subdirectory of
132    the root is under individual subversion control.  The stat-all.sh
133    and refresh-al.sh scripts apply "svn stat" or "svn update" to
134    each of these subtrees.
135    
136    ----------------------------------------------------------------------
137    Name: Matthias Blume (http://www.tti-c.org/blume/)
138    Date: 2006/11/02 12:20:00 CST
139    Description:
140    
141    Reorganized directory layout.
142    
143    This is a temporary solution, more reorganization is to come.
144    
145    The basic idea is to have a number of toplevel trees, each corresponding
146    to a well-defined part of the overall system.  Each part can be
147    maintained individually, even in separate source repositories,
148    although currently we still serve everything out of the main
149    smlnj-gforge tree.
150    
151    Installer and and scripts have been updated to reflect the new
152    layout.  The installer (base/src/system/smlnj/installer) is now
153    "scriptable" to avoid burning too much knowledge about the
154    layout into SML source code.  The main script used by the installer
155    is in config/actions.
156    
157    The main change is that many of the subdirectories of what used to
158    be known as "src" have moved to the toplevel.  The "src" directory
159    itself has moved down into a subtree called "base".  (We may eventually
160    get rid of the extra level of indirection represented by "src".)
161    
162    The layout is now as follows:
163    
164      toplevel tree name | default repository
165                         | (using gf=svn://smlnj-gforge.cs.uchicago.edu/smlnj)
166      -------------------+----------------------------------------------------
167      config             | $gf/config/trunk
168                         |
169      base               | $gf/sml/trunk
170                         |
171      smlnj-lib          | $gf/smlnj-lib/trunk
172      MLRISC             | $gf/MLRISC/trunk
173                         |
174      ml-yacc            | $gf/ml-yacc/trunk
175      ml-lex             | $gf/ml-lex/trunk
176      ml-burg            | $gf/ml-burg/trunk
177      lexgen             | $gf/lexgen/trunk
178      heap2asm           | $gf/heap2asm/trunk
179                         |
180      cml                | $gf/cml/trunk
181      eXene              | $gf/eXene/trunk
182      ckit               | $gf/ckit/trunk
183      nlffi              | $gf/nlffi/trunk
184                         |
185      smlnj-c            | $gf/smlnj-c/trunk
186    
187    In $gf/admin there are a few useful shell scripts for checking out
188    and maintaining the entire collection of trees:
189    
190       admin/checkout-all.sh [dir]
191          -- optionally creates dir and checks out all trees from their
192             default repositories; if dir is missing, checkout into .
193       admin/refresh-all.sh [dir]
194          -- looks at all trees (from the above list) in dir (default: .)
195             and runs "svn update" if the tree exists and is under
196             subversion control;
197             non-existing or non-subversion trees are skipped
198       admin/stat-all.sh [dir]
199          -- like refresh-all.sh, but runs "svn stat" instead

216    New working version (110.59).  NEW BOOTFILES!
217    
218    I am freezing 110.59.  Changes other than the version-number increase:
219    
220      eXene:
221    
222         * committed changes to eXene from Alley Stoughton:
223             "fixed bugs in X authorization and resource handling, as well
224              as in the pile and viewport widgets"
225    
226      Runtime:
227        * fixed linking problem with NetBSD 3.x.
228    
229      Lexgen:
230        * lexgen tool handles non-ascii characters in 7-bit mode the same
231          way that ml-lex does
232    
233        * lexgen propagates exceptions the same way that ml-lex does
234    
235      CML:
236        * Fixed a bug in the SyncVar polling functions (iGetPoll,
237          mTakePoll, and mGetPoll) that could lead to livelock.

380    
381    Enabling $/html-lib.cm in config/preloads did not work.  This is fixed
382    now.  (Since the anchor mapping for html-lib.cm is not yet in effect
383    at the time when config/preloads is processed, the library has to
384    be referred to by another name.  In 110.57 this would be
385    $SMLNJ-LIB/HTML/html-lib.cm.  I arranged for $smlnj/smlnj-lib/html-lib.cm
386    to be valid as well.)

441    Tag: blume-22051115-versiontool
442    Description:
443    
444    Reversed change to src/system/smlnj/internals/versiontool.cm.  This
445    file gets loaded as a tool -- by the equivalent of CM.make during the
446    run of CMB.make.  Thus, CMB's path configuration is meaningless for
447    it.  Instead, it has the status of "user code", so it should use
448    $/basis.cm to refer to the Basis library.  (At least that's true for
449    the purpose of bootstrapping the previous change.  In the future it
450    might make sense to have versiontool.cm refer to
451    $smlnj/basis/basis.cm, i.e., the version of the Basis that the
452    compiler itself uses.)

461    Description:
462    
463    This change affects the way the following libraries are tied into
464    the system:
465    
466       $/basis.cm
467       $/smlnj-lib.cm
468       $/pp-lib.cm
469       $/controls-lib.cm
470       $/html-lib.cm
471       $/ml-yacc-lib.cm
472    
473    These libraries are now internally (as seen from the source code
474    of the implementation itself) known by the following names:
475    
476       $smlnj/basis/basis.cm
477       $smlnj/smlnj-lib/smlnj-lib.cm
478       $smlnj/smlnj-lib/pp-lib.cm
479       $smlnj/smlnj-lib/controls-lib.cm
480       $smlnj/smlnj-lib/html-lib.cm
481       $smlnj/ml-yacc/ml-yacc-lib.cm
482    
483    This makes it possible to work with code that requires different
484    versions of these libraries, and which refers to these libraries using
485    their "default" names (i.e., the first set of names above).  In other
486    words, one can un-define or re-define those default names without
487    compromising the proper functioning of the compiler itself.
488    
489    A similar procedure had already been performed for several of the
490    MLRISC libraries that are linked into the compiler.  I did some
491    cleanup on this code.
492    
493    A new file in the config directory (named extrapathconfig) is
494    responsible for setting up path anchors that the compiler itself does
495    not need, but that are typically required by user code.

674    Tag: blume-20050516-redump-heap
675  Description:  Description:
676    
677    Added mechanism for re-creating a heap file for the interactive system
678    after configuration variables have been changed.
679    
680       CM.redump_heap : string -> unit
681    
682    This is much like SMLofNJ.exportML, but starting from the resulting
683    heap does not return to the caller of CM.redump_heap but
684    restarts the interactive system from scratch.  The original call of
685    CM.redump_heap does not return but ends the interactive session.
686    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
687    
688    Internally, redump_heap winds the dynamic execution context back to
689    the point where the original heap image was created and re-executes
690    the heap image generation code in the boot code.

806    Tag: blume-20050114-heap2exec
807    Description:
808    
809    Implemented new (but still experimental) heap2exec facility.  This is
810    tested under Mac OS X and should work under Linux (will test shortly).
811    It will probably also work on the Sparc (will test some time later).
812    
813      - removed old "HACKED_STANDALONE" hack from runtime
814    
815    To be able to test this, uncomment the request for "heap2asm" in
816    config/targets prior to installation.  (Notice that this is different
817    from "heap2exec" mentioned below.  Not a typo.)
818    
819    To perform an actual test, run the command
820    
821       $ bin/heap2exec heapfile execfile
822    
823    (You can put heap2exec on your shell's path.)
824    
825    For example, run
826    
827      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
828    
829    This will create a standalone executable called "mly" which you can
830    then invoke directly as a command.

926    Description:
927    
928    Hacked some of the scripts (in particular: the installer) to cope with
929    spaces in filenames a bit better.  But beware: the current "solution"
930    is likely still full of bugs and inherently incomplete.  (We need to
931    do away with those shell scripts for a comprehensive solution.)

975    Tag: blume-20041124-position
976    Description:
977    
978    The compiler can now be compiled in a mode that makes structure Position
979    equal to Int64.  The default, however, is unchanged (Position = Int31)
980    for the time being.
981    
982    To enable 64-bit positions, use the following procedure:
983    
984    1. Start sml
985    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
986    3. Type
987          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
988    4. Run CMB.make() as usual.
989    
990    This is barely tested.  The only test so far was a little SML program
991    counting the number of characters in an 8-gigabyte file by
992    reading it character-by-character.  That test was successful.
993    
994    In support of 64-bit positions, a number of new functions have been
995    added to the runtime system.

1038    - Stripped down the versiontool: It now only handles the version number.
1039      The date string is generated at bootstrap time (during makeml).
1040    
1041    - In a previous commit, fixed a minor issue with how polyequal is being
1042      translated.  In particular, the code now "looks through" abstractions.
1043      This results in slightly fewer polyEqual warnings and hopefully slightly
1044      more efficient code.  Important examples for where this matters are
1045      the new int64 and word64 types.

1061    
1062    All the pieces of Word64 are now there, with the exception of the
1063    conversions from and to LargeWord. (Eventually these need to be identities,
1064    but for the time being they don't even make sense because LargeWord is
1065    32-bit wide.)
1066    
1067    Also started to add similar support for Int64, but major pieces of that
1068    are still missing.

1074    Description:
1075    
1076    Structure Word64 is now (almost) complete, word literals and patterns
1077    seem to work.  There are a few odd pieces missing.  In particular,
1078    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
1079    at the moment.
1080    
1081    Making Word64 official would mean that LargeWord becomes Word64.  But
1082    this requires extreme care because most word-word conversions have to
1083    go through LargeWord, so making a mistake means loss of efficiency or
1084    worse.  Eventually there will be a solution similar to (but actually
1085    simpler than) what I did with IntInf.

1117      - Changend config/srcarchiveurl from a file just
1118        containing the URL string into a file containing
1119        shell script code.  The code has access to the $VERSION variable.
1120      - Made corresponding changes to config/install.sh and config/unpack.
1121      - Default contents of config/srcarchiveurl uses $VERSION and
1122        normally does not have to be edited to reflect a version change.
1123    
1124      (As a result, a version change can be done by just editing
1125       config/version, the rest is now automatic.)

1165    Tag: blume-20041020-standalone-backtrace
1166    Description:
1167    
1168    Added a mechanism for getting back-trace information from standalone
1169    programs.  Here is how it works:
1170    
1171       1. The part of the program from which you want to get backtrace
1172          information (usually the whole program) should be wrapped with
1173          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
1174          main program could be modified from something like
1175    
1176             fun main (pgm, args) = ...
1177    
1178         to
1179    
1180            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
1181    
1182       2. To be able to access BackTrace.monitor, you have to add
1183          library $smlnj-tdp/plugins.cm to the .cm file that contains your
1184          main function.
1185    
1186       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
1187          CM might have created in the past for your project).
1188    
1189       4. Build the system using this command line:
1190    
1191             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
1192                      myprog.cm MyProg.main myprog
1193    
1194          instead of the usual
1195    
1196             ml-build myprog.cm MyProg.main myprog
1197    
1198    I changed a library name:
1199    
1200       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
1201    
1202    New libraries:
1203    
1204       $smlnj-tdp/back-trace.cm
1205          -- when loaded causes the back-trace plugin to be installed
1206       $smlnj-tdp/coverage.cm
1207          -- when loaded causes the coverage plugin to be installed

1223    Description:
1224    
1225    * Test coverage tool added!
1226    * Further reorganization of tracing-, debugging-, and profiling support:
1227    
1228        - moved original BTImp -- now called BackTrace -- into a separate
1229          library called $/trace-debug-profile.cm
1230        - eliminated all mentions of BTrace from SMLofNJ.Internals
1231        - only the instrumentation mechanism is now left in the compiler proper
1232        - BackTrace module is a plugin which is NOT plugged in by default
1233        - Coverage module is another such plugin
1234    
1235    To get the benefits of any of these plugin modules, the code in
1236    question must be compiled with tdp instrumentation turned on.  This
1237    can be done by setting SMLofNJ.Internals.TDP.mode to true.
1238    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
1239    
1240    Plugins are selected at link time.  (Pre-compiled instrumented code
1241    can be re-loaded with different plugins in effect.)  When an
1242    instrumented module is linked, whatever plugins are at that time
1243    enabled will come into effect for that module.
1244    
1245    To enable the back-trace plugin, load library $/trace-debug-profile.cm
1246    and invoke BackTrace.install() (e.g., from the interactive prompt).
1247    To enable the coverage plugin, load the same library and invoke
1248    Coverage.install().
1249    
1250    Back-traces are generated automatically on uncaught exceptions and
1251    when the code in question explicitly invokes BackTrace.trigger().
1252    
1253    Coverage (and execution frequency-) information must be queried
1254    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

1276    This is is preparation of using the original back-trace
1277    instrumentation for other purposes.  "TDP" stands for
1278    Trace/Debug/Profile.
1279    
1280    The control flag controlling whether instrumentation is on or off is now
1281    registered under a different name, so instead of running sml as
1282    
1283     sml -Cinstrument.btrace-mode=true

1308    
1309    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
1310    is supposed to accept a tool argument called "source", but this did
1311    not work because of the clash with the keyword.

1364      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
1365      Also, loading the versiontool does not work when rebuilding the system
1366      because CM is not properly initialized at that time.

1372    Description:
1373    
1374    Implemented some CM magic to have
1375        file src/compiler/TopLevel/main/version.sml
1376    generated automagically.
1377    The version is taken from two files: config/version and config/release.
1378    The first is expected to contain a two-part version number such as 110.49.
1379    The second should contain a single number, but it may be missing.
1380    
1381    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
1382    time the version tool is loaded (which is the first time you say CMB.make),
1383    then the tool will increment the value stored in config/release every
1384    time CMB.make is invoked.
1385    
1386    The binfile format is now insensitive to anything beyond the first
1387    two components of a version number, so bumping the release does not render
1388    binfiles incompatible.  Auto-bumping can be used to keep track of versions
1389    during development without invalidating existing binfiles.
1390    
1391    In any case, every CMB.make updates the date information in version.sml.
1392    (This is the date that is printed in the banner.)

1405    Tag: blume-20040927-controls
1406    Description:
1407    
1408    Added two pieces of functionality to the Controls interface:
1409    
1410    1.   val save'restore: 'a control -> unit -> unit
1411    
1412       grabs the current value of the control in stage 1 and restores it
1413       in stage 2.
1414    
1415    2.   val set' : 'a control * 'a -> unit -> unit
1416    
1417       stores the given value into the control in stage 2 (i.e., delayed)
1418       but does all error checking in stage 1.
1419       (This is for string controls that need to do parse their argument --
1420        something that might fail.  In some cases, notably in CM, one
1421        already knows the intended argument but wants to delay the actual
1422        assignment until a time when error recovery would be more difficult.)
1423    
1424    Changed the handling of controls in tool arguments to classes "sml" and
1425    "lazysml":
1426       - use Controls.save'restore as a more robust way of restoring the
1427         old value (in particular: without having to re-parse the string)
1428       - use controls to handle the "overload" keyword in the init group
1429         (I believe this change actually fixes a long-standing obscure bug.)

1434    Tag: blume-20040927-lazysml
1435    Description:
1436    
1437    Added a new tool class called "lazysml" to CM's tool chest.  The only
1438    difference to "sml" is that compilation is done with Control.lazysml
1439    set to true.  A source of class "lazysml" is automatically recognized
1440    by a file name suffix of ".lml".
1441    
1442    In addition to the above feature, the original class "sml" now also
1443    supports a tool argument "lazy" which has the same effect.  As a
1444    result, the following three lines are equivalent:
1445    
1446        foo.sml : lazysml
1447        foo.sml : sml (lazy)
1448        foo.sml (lazy)
1449    
1450    The setting goes into effect both during parsing and during
1451    compilation.  The original setting is restored right after parsing and
1452    after compilation, respectively.
1453    
1454    In addition to all the above, there is also a general mechanism to set
1455    ANY of the "controls" that are available at the command line via
1456    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
1457    apply as well. (In fact, "lazy" is implemented as a special case of
1458    the general mechanism.)
1459    
1460    The .cm file syntax uses a new keyword tool argument called "with".
1461    There are several ways of indicating the desired settings:
1462    
1463        foo.sml (with:parser.quotations=true)
1464        foo.sml (with:(name:parser.quotations value:true))
1465        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
1466        foo.sml (with:(name1=value1 name2=value2 ...))
1467        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
1468    
1469        etc.
1470    
1471    Another possible abbreviation is to leave out the =v or value:v part
1472    if the name refers to a boolean control (in which case the value is
1473    taken to be true).  Thus, one could get lazy sml also by saying:
1474    
1475        foo.sml (with:parser.lazy-keyword=true)
1476        foo.sml (with:parser.lazy-keyword)
1477        foo.sml (with:(name:parser.lazy-keyword value:true))
1478        foo.sml (with:(name:parser.lazy-keyword))

1795    
1796    NLFFI under Mac OS X now working (sort of).  This is largely untested,
1797    though.
1798    
1799    Note:  1. You have to make a new, clean build of the runtime system.
1800           2. There are new BOOTFILES, you have to use them!
1801              (Doing the bootstrap process yourself would be *very* painful!
1802               If you absolutely have to do it, build the system under
1803               a different architecture and then cross-compile.)
1804    
1805    Version bumped to 110.46.1 to account for runtime data format changes.

1813    Changed the implementation of structure Unix so that the same stream
1814    is returned every time one of the {text,bin}{In,Out}streamOf functions
1815    is invoked on the same proc.  This is not what the spec currently
1816    says -- although IMO it arguably should.  (See discussion below.)

1830    Description:
1831    
1832    Changed the interface of structures Timer and Unix to match the most
1833    recent Basis spec.
1834    
1835    In the case of Unix there still seems to be an open/weird issue:
1836    
1837       The {text,bin}{In,Out}streamOf functions are supposed to create
1838       fresh streams whenever they are called -- as opposed to have them
1839       return the same stream every time.  This design is supposed to
1840       prevent space leaks caused by proc values hanging on to streams.
1841    
1842       The reap function, on the other hand, is supposed to close the
1843       streams.  This cannot be done without having a handle on the
1844       stream in proc after all...
1845    
1846    I took the liberty to implement the following stopgap solution:
1847    
1848      The proc value hangs on to the most recently created stream(s).
1849      Reap closes those.  If either or both of the two streams hadn't
1850      been created at all yet, then reap will close the corresponding
1851      file descriptors directly.
1852    
1853    PS: I don't understand the original space leak argument anymore.  If
1854    a proc hangs on to the imperative stream, then I/O operations on those
1855    will advance the state of the cached stream and avoid the space leak.

1869    Description:
1870    
1871    CM now ignores (but still accepts) the "owner" information in group
1872    descriptions.  The owner of a group is its next enclosing
1873    library. Each group must have a unique owner.  (There is a virtual
1874    "toplevel" library that owns groups which are not nested within a real
1875    library.)  Previously, each group had to explicitly declare its owner,
1876    and CM would check that such a declaration is correct.  The new scheme
1877    is to have CM check that for each group there is precisely one owning
1878    library.
1879    
1880    The advantage of the new scheme is that the programmer no longer needs
1881    to maintain the somewhat annoying owner information.  The downside is
1882    that CM cannot enforce the ownership rule across multiple runs of
1883    CM.make.  Fortunately, enclosing the same group in two different
1884    libraries A and B which are not part of the same program does not
1885    cause real problems.

1904    Description:
1905    
1906    Arranged for ml-build to clean up after itself a little bit better.
1907    The script generates a temporary SML source file and compiles it using
1908    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
1909    gets rid of those at the end, so they don't accumulate under .cm.
1910    
1911    This required a minor change to install.sh because the name of the
1912    metadata directory (default: .cm) is actually configurable at
1913    installation time.

1928    Description:
1929    
1930    Added previously missing support for many socket-related functions
1931    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
1932    for the voluminous patch!
1933    
1934    (I have not tested this patch under win32 yet.)
1935    
1936    Here is David's e-mail:
1937    
1938    Hi,
1939    
1940    Attached to this email you find a diff against sml/nj 110.45
1941    that will enable socket support under Windows.
1942    
1943    To apply the patch (using unix or cygwin)
1944    1) gunzip runtime.diff.gz
1945    2) "cd" into "src/runtime" in the source tree of a fresh
1946       110.45 installation.
1947    3) patch -p 1 < [your/path/to]runtime.diff
1948    
1949    The code compiles fine but has NOT yet been extensively tested.
1950    I only ran a few tests for basic socket client functionality
1951    (which worked fine).  Especially the functions that use ioctl
1952    are not tested at all and might not work (see below).
1953    
1954    I implemented this since we want to move to a newer version of sml/nj
1955    but need socket support in order to use it.  This is the first time I
1956    even had a look at the sml/nj source,  so please review my changes
1957    before making this part of the distribution!  Here are a few issues
1958    that I think might be better for someone to solve who is more
1959    familiar with the sml/nj source (and socket programming):
1960    
1961    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
1962      exception since I could not figure out what the windows equivalent
1963      of these functions is
1964    
1965    - In sockets-osdep.h there are a some #include statements that are
1966      only used in a few files that include sockets-osdep.h
1967    
1968    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
1969      does not process its return value since I don't know how to
1970      report an error upwards.
1971    
1972    - It would probably be good to have a call to WSACleanup() when
1973      the library is unloaded (if there is such a possibility).
1974      Otherwise I think Windows will take care of this automatically
1975      when the process finishes.
1976    
1977    - I used ioctlsocket() as a replacement for ioctl() but I have
1978      no idea if that is actually the proper replacement on Windows.
1979    
1980    - All these issues are marked in the code by "FIXME" comments.
1981    
1982    We use sml/nj extensively in our products and are quite happy
1983    with it.  I hope this contribution will help you.
1984    
1985    Keep up the good work!
1986

2025    in the "targets" file, then the installer will pull in sources for
2026    everything.  (Notice that this refers to source code only.  Compiled
2027    code is still only installed for modules that were requested explicitly
2028    or which are required for other modules that were requested explicitly.)

2064    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version

2066    
2067       lib = dlopen(NULL, ...)
2068       f   = dlsym(lib, "malloc");
2069    
2070    does not work on Windows unless we explicitly export symbols
2071    such as 'malloc' during linking.  We fixed this by explicitly
2072    exporting the required symbols with the magic gcc incantation:
2073    
2074        -Wl,--export-all cygwin.def
2075    
2076    where cygwin.def is a file containing all the symbols that
2077    we wish to export.
2078    
2079    I suspect this is a Windows problem and we'll have to
2080    do the same (somehow with windows compilers) when
2081    we build the native win32 version with the system
2082    calls LoadLibrary/GetProcAddress.

2213    appears in CM's autoload registry.  As a result, we see far fewer of
2214    those ?.Foo.Bar.xxx names in the prettyprinter's output.
2215    
2216    In addition to this I tried to clean up some pieces of the Basis
2217    implementation (e.g., Socket, Word8Array) in order to prevent other
2218    instances of these ?.Foo.Bar.xxx names from being printed.
2219    
2220    The mechanism that picks names for types still needs some work, though.
2221    (Right now it seems that if there is a type A.t which is defined to
2222    be B.u, but B is unavailable at toplevel, then A.t gets printed as
2223    "?.B.u" although the perhaps more sensible solution would be to use
2224    "A.t" in this case.  In other words, the prettyprinter should follow
2225    a chain of DEFtycs not farther than there are corresponding toplevel
2226    names in the current environment.)

2232    Description:
2233    
2234    Another installer tweak:  All the ML code for the installer is now
2235    compiled during CMB.make and put into a little library called
2236    $smlnj/installer.cm.  The installation then simply invokes
2237    
2238       sml -m $smlnj/installer.cm
2239    
2240    and everything happens automagically.
2241    
2242    Win32:  ML code senses value of environment variable SMLNJ_HOME.
2243    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
2244            and BINDIR.
2245    
2246    The new scheme guarantees that the ML code responsible for the installation
2247    is in sync with the APIs of the main system.  Also, the installer is
2248    somewhat faster because the installer script is precompiled.

2256    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
2257    but excludes all non-blocking operations.  Defined SOCKET (in Basis)

2259    implementations of non-blocking operations from CML's Socket
2260    structure.

2266    Description:
2267    
2268    1. Fixed SOCKET API and implementation to match Basis spec.
2269       This required changing the internal representation of sockets to one
2270       that remembers (for each socket file descriptor) whether it is currently
2271       blocking or non-blocking.  This state is maintained lazily (i.e., a system
2272       call is made only if the state actually needs to change).
2273    
2274    2. OS-specific details of sockets were moved into separate files, thus
2275       making it possible to unify the bulk of the socket implementations
2276       between Unix and Win32.
2277    
2278    3. CML's socket API changed accordingly.
2279       (Note that we need to remove non-blocking functions from this API
2280       since they are redundant in the case of CML!)
2281    
2282    4. CML's socket implementation now makes use of non-blocking functions
2283       provided by Basis, thus removing all OS-dependent code from this part
2284       of CML.
2285    
2286    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

2399    Description:
2400    
2401    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
2402    Modified config/install.bat to take advantage of it.  Also modified
2403    config/install.sh (and called it config/new-install.sh) to take advantage
2404    of it on Unix systems.  (The SML code is (supposed to be) platform-
2405    independent.)
2406    
2407    The installer can now install everything under Win32
2408    as well as under *nix as long as it compiles.
2409    
2410    Other changes:
2411    
2412      - made CML compile again under Win32
2413      - made eXene compile under Win32 (by providing a fake structure UnixSock
2414        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
2415      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
2416        same as type int;  under Win32 it isn't
2417      - fixed some slice-related problems in the win32-specific parts of CML
2418      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
2419        (under Win32, the volume name is case-insensitive, and the
2420        OS.Path code compares volume names for equality)

2437    Description:
2438    
2439      1. Changed interface to vectors and arrays in Basis to match
2440         (draft) Basis spec.
2441      2. Added signatures and implementations of slices according to
2442         Basis spec.
2443      3. Edited source code throughout the system to make it compile again
2444         under 1. and 2.  (In some cases code had to be added to have it
2445         match the new signatures.)
2446      4. MLRISC should be backward-compatible: the copies of the originals
2447         of files that needed to change under 3. were retained, the .cm files
2448         check the compiler version number and use old versions when
2449         appropriate.
2450      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
2451         dirstream -> string option (in accordance with Basis spec).
2452      6. When generating code that counts lines, ml-lex used function
2453         CharVector.foldli, taking advantage of its old interface.
2454         This has been replaced with the corresponding code from
2455         CharVectorSlice.  (html-lex must be re-lexed!)
2456      7. BitArray in smlnj-lib/Util has been extended/modified to match the
2457         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
2458      8. Removed temporary additions (fromInternal, toInternal) from the
2459         (now obsolete) IntInf in smlnj-lib/Util.
2460      9. Cleaned up structure Byte.
2461     10. Added localOffset, scan, and fromString to Date (according to spec).
2462         Cleaned/corrected implementation of Date.
2463         (Still need to check for correctness; implement better canonicalizeDate.)
2464     11. Added "scan" to signature IEEE_REAL.
2465     12. Some improvements to IntInf [in particular: efficiency-hack for
2466         mod and rem when second operand is 2 (for parity checks).]
2467     13. Changed representation of type Time.time, using a single IntInf.int
2468         value counting microseconds.  This considerably simplified the
2469         implementation of structure Time.  We now support negative time
2470         values; scan and fromString handle signs.
2471     14. Functor PrimIO now takes two additional arguments (VectorSlice and
2472         ArraySlice).

2478    Description:
2479    
2480    This is a major update which comes with a version number bump
2481    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
2482    and an implementation of IntInf in the Basis.
2483    
2484    There are a fairly large number of related changes and updates throughout
2485    the system:
2486    
2487    Basis:
2488            - Implemented IntInf.
2489            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
2490            - Added some missing Real64 operations, most notably Real.toLargeInt.
2491            - Added FixedInt as a synonym for Int32.
2492    
2493    compiler:
2494            * Added support for a built-in intinf type.
2495              - literals
2496              - pattern matching
2497              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
2498              - overloading on literals and operations
2499    
2500            This required adding a primitive type intinf, some additional
2501            primops, and implementations for several non-trivial intinf
2502            operations in Core.  (The intinf type is completely abstract
2503            to the compiler; all operations get delegated back to the Core.)
2504    
2505            * Intinf equality is handled by polyequal.  However, the compiler
2506            does not print its usual warning in this case (since polyequal
2507            is the right thing to do there).
2508    
2509            * Improved the organization of structure InlineT.
2510    
2511            * A word about conversion primops:
2512            If conversions involving intinf do not cancel out during
2513            CPS contract, then the compiler must insert calls to Core functions.
2514            Since all core access must be resolved already during the FLINT
2515            translate phase, it would be too late a the time of CPS contract
2516            to add new Core calls.  For this reason, conversion primops
2517            for intinf carry two arguments:  1. the numeric argument that
2518            they are supposed to convert, and 2. the Core function that
2519            can help with this conversion if necessary.  If CPS contract
2520            eliminates a primop, then the associated Core function becomes
2521            dead and goes away.  Intinf conversion primops that do not get
2522            eliminated by CPS contract get rewritten into calls of their
2523            core functions by a separate, new phase.
2524    
2525    interactive system:
2526            - Control.Print.intinfDepth controls max length of intinf constants
2527            being printed. (Analogous to Control.Print.stringDepth.)
2528            - Cleanup in printutil and pputil: got rid of unused stuff and
2529            duplicates; replaced some of the code with code that makes better
2530            use of library functionality.
2531    
2532    CM:
2533            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
2534            are no longer silent.
2535    
2536    CKIT:
2537            Fixed mismatched uses of Int32 and LargeInt.  I always decided
2538            in favor of LargeInt -- which is now the same as IntInf.
2539            CKIT-knowledgable people should check whether this is what's
2540            intended and otherwise change things back to using Int32 or
2541            FixedInt.
2542    
2543    Throughout the code:
2544            Started using IntInf.int literals and built-in operations
2545            (e.g., comparison with 0) where this seems appropriate.

2566    
2567    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
2568    
2569        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
2570    
2571    This patch restores SML/NJ's ability to run under win32.  There are a
2572    number of changes, including fixes for several bugs that had gone
2573    unnoticed until now:
2574    
2575      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
2576        trying to run the win32 version from within cygwin.)
2577    
2578      - There are a number of simple .bat scripts that substitute for their
2579        corresponding Unix shell-scripts.  (See below.)
2580    
2581      - The internals of ml-build have been modified slightly.  The main
2582        difference is that instead of calling ".link-sml" (or link-sml.bat)
2583        using OS.Process.system, the ML process delegates this task back
2584        to the script.  Otherwise problems arise in mixed environments such
2585        as Cygwin where scripts look and work like Unix scripts, but
2586        where OS.Process.system cannot run them.
2587    
2588      - In CM, the srcpath pickler used native pathname syntax -- which
2589        is incorrect in the case of cross-compilation.  The new pickle format
2590        is independent of platform-specific naming conventions.
2591    
2592      - Path configuration files (such as lib/pathconfig) can now choose
2593        between native and standard syntax.  Placing a line of the form
2594    
2595            standard!
2596    
2597        into the file causes all subsequent paths to be interpreted using
2598        CM standard pathname syntax (= Unix conventions); a line
2599    
2600            native!
2601    
2602        switches back to native style.  This was needed so that
2603        path config files can be written portably, see src/system/pathconfig.
2604    
2605      - Runtime system:
2606    
2607          - win32-filesys.c:  get_file_time and set_file_time now
2608            access modification time, not creation time.
2609    
2610          - I/O code made aware of new array representation.
2611    
2612          - Bug fixes in X86.prim.masm.
2613    
2614       - src/system/makeml made aware of win32. (For use under cygwin
2615            and other Unix-environments for windows.)
2616    
2617       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
2618         which caused BinIO.inputAll to fail consistently.
2619    
2620    .bat scripts:
2621    
2622       Windows .bat scripts assume that SMLNJ_HOME is defined.
2623    
2624       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
2625         applications (sml, ml-yacc, ml-lex).
2626       - ml-build.bat: analogous to ml-build.
2627       - config\install.bat:  Analogous to config/install.sh.  This requires
2628         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
2629         (nmake etc. must be on the path, and vcvars32 must have been run.)
2630         Moreover, sources for ml-lex and ml-yacc need to exist under src,
2631         and the bootfile hierarchy must have been unpacked under
2632         sml.boot.x86-win32.
2633         The script is very primitive and does a poor job at error checking.
2634         It only installs the base system, ml-lex, and ml-yacc.  No other
2635         libraries are being installed (i.e., you get only those that
2636         are part of the compiler.)
2637       - link-sml.bat:  analogous to .link-sml, but not currently used
2638    
2639    Unrelated bug fixes:
2640    
2641      - ml-nlffigen now exports structures ST_* corresponding to incomplete
2642        types.
2643      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
2644        otherwise.)

2682    
2683    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
2684    
2685       This mainly affects the quality of error messages.  However, some
2686       of the code is now more straightforward than before. (Treatment of
2687       the above four constructs in translate.sml is much simpler than
2688       the "macro-expansion" that was going on before.  Plus, the mach-
2689       compiler no longer gets invoked just to be able to compile an
2690       if-expression.)
2691    
2692    2. The ErrorMsg.Error exception is now caught and absorbed by the
2693       interactive loop.

2700    
2701        Ported the runtime system to cygwin, which uses the unix
2702    x86-unix bin files.  Missing/buggy features:
2703    
2704       o getnetbyname, getnetbyaddr: these functions seem to be missing in
2705         the Cygwin library.
2706       o Ctrl-C handling may be flaky.
2707       o Windows system calls and Windows I/O are not supported.
2708    
2709       A new set of binfiles is located at:
2710    
2711         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
2712    
2713       This is only needed for bootstrapping the cygwin version of smlnj.

2776    (see below).
2777    
2778    The change solves a problem with two competing approaches the
2779    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
2780    each other's way.

2812    to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
2813    the entire tree to some other place and everything will "just work".

2978    1. Pushed new controls interface through compiler so that everything

2980    
2981    2. Added FormatComb and FORMAT_COMB to the CML version of the
2982       SML/NJ library (so that CML compiles again).
2983    
2984    3. Modified init scripts because XXX_DEFAULT environment variables

2993    Description:
2994    
2995            All pseudo-ops emitted before the first segment declaration
2996    such as TEXT, DATA, and BSS directives are assumed to be global
2997    declarations and are emitted first in the assembly file. This is
2998    useful in a number of situations where one has pseudo-ops that are not
2999    specific to any segment, and also works around the constraint that one
3000    cannot have client pseudo-ops in the TEXT segment.
3001    
3002            Because no segment is associated with these declarations it is
3003    an error to allocate any space or objects before the first segment
3004    directive and an exception will be raised. However, we cannot make
3005    this check for client pseudo-ops.
3006    
3007            These top level declarations are a field in the CFG graph_info.
3008    In theory you can continue to add to this field after the CFG has been
3009    built -- provided you know what you are doing;-)

3033    
3034    Applied the following bugfix provided by Emden Gansner:
3035    
3036        Output is corrupted when outputSubstr is used rather than output.
3037    
3038        The problem occurs when a substring
3039    
3040            ss = (s, dataStart, dataLen)
3041    
3042        where dataStart > 0, fills a stream buffer with avail bytes left.
3043        avail bytes of s, starting at index dataStart, are copied into the
3044        buffer, the buffer is flushed, and then the remaining dataLen-avail
3045        bytes of ss are copied into the beginning of the buffer. Instead of
3046        starting this copy at index dataStart+avail in s, the current code
3047        starts the copy at index avail.
3048    
3049        Fix:
3050        In text-io-fn.sml, change line 695 from
3051             val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
3052        to

3069    Description:
3070    
3071    Added full support for div/mod/rem/quot on the x86, using the machine
3072    instruction's two results (without clumsily recomputing the remainder)
3073    directly where appropriate.
3074    
3075    Some more extensive power-of-two support was added to the x86 instruction
3076    selector (avoiding expensive divs, mods, and muls where they can be
3077    replaced with cheaper shifts and masks).  However, this sort of thing
3078    ought to be done earlier, e.g., within the CPS optimizer so that
3079    all architectures benefit from it.
3080    
3081    The compiler compiles to a fixed point, but changes might be somewhat
3082    fragile nevertheless.  Please, report any strange things that you might
3083    see wrt. div/mod/quot/rem...

3089    Description:
3090    
3091    Fixed my broken div/mod logic.  Unfortunately, this means that the
3092    inline code for div/mod now has one more comparison than before.
3093    Fast paths (quotient > 0 or remainder = 0) are not affected, though.
3094    The problem was with quotient = 0, because that alone does not tell
3095    us which way the rounding went.  One then has to look at whether
3096    remainder and divisor have the same sign...  :(
3097    
3098    Anyway, I replaced the bootfiles with fresh ones...

3104    Description:
3105    
3106    NEW BOOTFILES!!!    Version number bumped to 110.39.3.
3107    
3108    Primops have changed. This means that the bin/boot-file formats have
3109    changed as well.
3110    
3111    To make sure that there is no confusion, I made a new version.
3112    
3113    
3114    CHANGES:
3115    
3116    * removed REMT from mltree (remainder should never overflow).
3117    
3118    * added primops to deal with divisions of all flavors to the frontend
3119    
3120    * handled these primops all the way through so they map to their respective
3121      MLRISC support
3122    
3123    * used these primops in the implementation of Int, Int32, Word, Word32
3124    
3125    * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
3126    
3127    * parameterized INLMIN, INLMAX, and INLABS by a numkind
3128    
3129    * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
3130      floating point
3131    
3132    * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
3133      and Real (but Real.abs maps to a separate floating-point-only primop)
3134    
3135    
3136    TODO items:
3137    
3138    * Hacked Alpha32 instruction selection, disabling the selection of REMx
3139      instructions because the machine instruction encoder cannot handle
3140      them.  (Hppa, PPC, and Sparc instruction selection did not handle
3141      REM in the first place, and REM is supported by the x86 machine coder.)
3142    
3143    * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
3144      selection phase.  (The two can be streamlined because the hardware
3145      delivers both quotient and remainder at the same time anyway.)
3146    
3147    * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
3148      (Currently the behavior is inconsistent both across architectures and
3149      wrt. the draft Basis spec.)
3150    
3151    * Word8 should eventually be handled natively, too.
3152    
3153    * There seems to be one serious bug in mltree-gen.sml.  It appears, though,
3154      as if there currently is no execution path that could trigger it in
3155      SML/NJ.  (The assumptions underlying functions arith and promotable do not
3156      hold for things like multiplication and division.)
