19    Description:
20    
21    Some rationalization of names:
22    
23       structure BTrace -> structure TDPInstrument
24       etc.
25    
26    This is is preparation of using the original back-trace
27    instrumentation for other purposes.  "TDP" stands for
28    Trace/Debug/Profile.
29    
30    The control flag controlling whether instrumentation is on or off is now
31    registered under a different name, so instead of running sml as
32    
33     sml -Cinstrument.btrace-mode=true
34    
35    one has to say
36    
37     sml -Ctdp.instrument=true

43    Description:
44    
45    Made some minor modifications to elabcore.sml to have source regions
46    be propagated more tightly -- resulting in better (i.e., smaller)
47    regions being reported in error- and debug messages.

52    Tag: blume-20041008-cmkw
53    Description:
54    
55    Fixed handling of keywords in .cm files: After seeing "is" the lexer
56    treats subsequent occurrences of "group", "library", "source", "is",
57    "*", and "-" as ordinary identifiers rather than keywords.
58    
59    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
60    is supposed to accept a tool argument called "source", but this did
61    not work because of the clash with the keyword.

67    Description:
68    
69    Assorted cleanup work:
70    
71      - got rid of intstrmap in favor of using the library's
72        hash table implementation
73      - threw out most of the pathnames stuff, as it was not used anyway
74      - simplified tokentable implementation
75      - fixed some minor spelling errors

81    Description:
82    
83    Cleaned up the absyn to reflect the invariant that HANDLE always
84    carries a FNexp as part of the type definition.  This eliminates some
85    superfluous sanity checks at runtime down the road.
86    
87    Some minor cleanup of the btrace code.

92    Tag: blume-20041001-slave
93    Description:
94    
95    Added hack to make slave mode work in the presence of the version
96    tool.  (Still, since the master does two passes over the code for
97    CMB.make, the release number gets bumped twice when slaves are
98    attached.  I don't know if this is worth fixing...)

103    Tag: blume-20040930-version
104    Description:
105    
106    * Moved the "version" magic into its own little library under
107    src/system/smlnj/internal.  This avoids expensive reconstruction
108    of a stable src/compiler/core.cm.
109    
110    * At the same time, structure CompilerVersion is now known as structure
111    SMLNJVersion.
112    
113    * Arranged for the version tool to NOT kick in when rebuilding the system
114      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
115      Also, loading the versiontool does not work when rebuilding the system
116      because CM is not properly initialized at that time.

121    Tag: blume-20040929-autoversion
122    Description:
123    
124    Implemented some CM magic to have
125        file src/compiler/TopLevel/main/version.sml
126    generated automagically.
127    The version is taken from two files: config/version and config/release.
128    The first is expected to contain a two-part version number such as 110.49.
129    The second should contain a single number, but it may be missing.
130    
131    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
132    time the version tool is loaded (which is the first time you say CMB.make),
133    then the tool will increment the value stored in config/release every
134    time CMB.make is invoked.
135    
136    The binfile format is now insensitive to anything beyond the first
137    two components of a version number, so bumping the release does not render
138    binfiles incompatible.  Auto-bumping can be used to keep track of versions
139    during development without invalidating existing binfiles.
140    
141    In any case, every CMB.make updates the date information in version.sml.
142    (This is the date that is printed in the banner.)

147    Tag: blume-20040928-controls
148    Description:
149    
150    Some cleanup of the controls code.
151    
152    ----------------------------------------------------------------------
153    Name: Matthias Blume (blume (at) tti - c (dot) org)
154    Date: 2004/09/27 22:08:00 CDT
155    Tag: blume-20040927-controls
156    Description:
157    
158    Added two pieces of functionality to the Controls interface:
159    
160    1.   val save'restore: 'a control -> unit -> unit
161    
162       grabs the current value of the control in stage 1 and restores it
163       in stage 2.
164    
165    2.   val set' : 'a control * 'a -> unit -> unit
166    
167       stores the given value into the control in stage 2 (i.e., delayed)
168       but does all error checking in stage 1.
169       (This is for string controls that need to do parse their argument --
170        something that might fail.  In some cases, notably in CM, one
171        already knows the intended argument but wants to delay the actual
172        assignment until a time when error recovery would be more difficult.)
173    
174    Changed the handling of controls in tool arguments to classes "sml" and
175    "lazysml":
176       - use Controls.save'restore as a more robust way of restoring the
177         old value (in particular: without having to re-parse the string)
178       - use controls to handle the "overload" keyword in the init group
179         (I believe this change actually fixes a long-standing obscure bug.)
180

183    Date: 2004/09/27 17:00:00 CDT
184    Tag: blume-20040927-lazysml
185    Description:
186    
187    Added a new tool class called "lazysml" to CM's tool chest.  The only
188    difference to "sml" is that compilation is done with Control.lazysml
189    set to true.  A source of class "lazysml" is automatically recognized
190    by a file name suffix of ".lml".
191    
192    In addition to the above feature, the original class "sml" now also
193    supports a tool argument "lazy" which has the same effect.  As a
194    result, the following three lines are equivalent:
195    
196        foo.sml : lazysml
197        foo.sml : sml (lazy)
198        foo.sml (lazy)
199    
200    The setting goes into effect both during parsing and during
201    compilation.  The original setting is restored right after parsing and
202    after compilation, respectively.
203    
204    In addition to all the above, there is also a general mechanism to set
205    ANY of the "controls" that are available at the command line via
206    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
207    apply as well. (In fact, "lazy" is implemented as a special case of
208    the general mechanism.)
209    
210    The .cm file syntax uses a new keyword tool argument called "with".
211    There are several ways of indicating the desired settings:
212    
213        foo.sml (with:parser.quotations=true)
214        foo.sml (with:(name:parser.quotations value:true))
215        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
216        foo.sml (with:(name1=value1 name2=value2 ...))
217        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
218    
219        etc.
220    
221    Another possible abbreviation is to leave out the =v or value:v part
222    if the name refers to a boolean control (in which case the value is
223    taken to be true).  Thus, one could get lazy sml also by saying:
224    
225        foo.sml (with:parser.lazy-keyword=true)
226        foo.sml (with:parser.lazy-keyword)
227        foo.sml (with:(name:parser.lazy-keyword value:true))
228        foo.sml (with:(name:parser.lazy-keyword))

253    
254    1. Changed definition of type ControlRegistry.registry_tree to
255       include control_info (i.e., the name of the controlling environment
256       variable).
257    
258    2. Added command-line flags -e and -E to print the names of environment
259       variables that can be used to control internal settings.
260       (This uses the new API mentioned in 1.)

580    Description:
581    
582    Changed the interface of structures Timer and Unix to match the most
583    recent Basis spec.
584    
585    In the case of Unix there still seems to be an open/weird issue:
586    
587       The {text,bin}{In,Out}streamOf functions are supposed to create
588       fresh streams whenever they are called -- as opposed to have them
589       return the same stream every time.  This design is supposed to
590       prevent space leaks caused by proc values hanging on to streams.
591    
592       The reap function, on the other hand, is supposed to close the
593       streams.  This cannot be done without having a handle on the
594       stream in proc after all...
595    
596    I took the liberty to implement the following stopgap solution:
597    
598      The proc value hangs on to the most recently created stream(s).
599      Reap closes those.  If either or both of the two streams hadn't
600      been created at all yet, then reap will close the corresponding
601      file descriptors directly.
602    
603    PS: I don't understand the original space leak argument anymore.  If
604    a proc hangs on to the imperative stream, then I/O operations on those
605    will advance the state of the cached stream and avoid the space leak.

618    Tag: blume-20040525-group-owner
619    Description:
620    
621    CM now ignores (but still accepts) the "owner" information in group
622    descriptions.  The owner of a group is its next enclosing
623    library. Each group must have a unique owner.  (There is a virtual
624    "toplevel" library that owns groups which are not nested within a real
625    library.)  Previously, each group had to explicitly declare its owner,
626    and CM would check that such a declaration is correct.  The new scheme
627    is to have CM check that for each group there is precisely one owning
628    library.
629    
630    The advantage of the new scheme is that the programmer no longer needs
631    to maintain the somewhat annoying owner information.  The downside is
632    that CM cannot enforce the ownership rule across multiple runs of
633    CM.make.  Fortunately, enclosing the same group in two different
634    libraries A and B which are not part of the same program does not
635    cause real problems.

654    Description:
655    
656    Arranged for ml-build to clean up after itself a little bit better.
657    The script generates a temporary SML source file and compiles it using
658    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
659    gets rid of those at the end, so they don't accumulate under .cm.
660    
661    This required a minor change to install.sh because the name of the
662    metadata directory (default: .cm) is actually configurable at
663    installation time.

678    Description:
679    
680    Added previously missing support for many socket-related functions
681    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
682    for the voluminous patch!
683    
684    (I have not tested this patch under win32 yet.)
685    
686    Here is David's e-mail:
687    
688    Hi,
689    
690    Attached to this email you find a diff against sml/nj 110.45
691    that will enable socket support under Windows.
692    
693    To apply the patch (using unix or cygwin)
694    1) gunzip runtime.diff.gz
695    2) "cd" into "src/runtime" in the source tree of a fresh
696       110.45 installation.
697    3) patch -p 1 < [your/path/to]runtime.diff
698    
699    The code compiles fine but has NOT yet been extensively tested.
700    I only ran a few tests for basic socket client functionality
701    (which worked fine).  Especially the functions that use ioctl
702    are not tested at all and might not work (see below).
703    
704    I implemented this since we want to move to a newer version of sml/nj
705    but need socket support in order to use it.  This is the first time I
706    even had a look at the sml/nj source,  so please review my changes
707    before making this part of the distribution!  Here are a few issues
708    that I think might be better for someone to solve who is more
709    familiar with the sml/nj source (and socket programming):
710    
711    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
712      exception since I could not figure out what the windows equivalent
713      of these functions is
714    
715    - In sockets-osdep.h there are a some #include statements that are
716      only used in a few files that include sockets-osdep.h
717    
718    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
719      does not process its return value since I don't know how to
720      report an error upwards.
721    
722    - It would probably be good to have a call to WSACleanup() when
723      the library is unloaded (if there is such a possibility).
724      Otherwise I think Windows will take care of this automatically
725      when the process finishes.
726    
727    - I used ioctlsocket() as a replacement for ioctl() but I have
728      no idea if that is actually the proper replacement on Windows.
729    
730    - All these issues are marked in the code by "FIXME" comments.
731    
732    We use sml/nj extensively in our products and are quite happy
733    with it.  I hope this contribution will help you.
734    
735    Keep up the good work!
736    
737    David

812    Description:
813    
814    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
815    of SML/NJ.  The problem is that
816    
817       lib = dlopen(NULL, ...)
818       f   = dlsym(lib, "malloc");
819    
820    does not work on Windows unless we explicitly export symbols
821    such as 'malloc' during linking.  We fixed this by explicitly
822    exporting the required symbols with the magic gcc incantation:
823    
824        -Wl,--export-all cygwin.def
825    
826    where cygwin.def is a file containing all the symbols that
827    we wish to export.
828    
829    I suspect this is a Windows problem and we'll have to
830    do the same (somehow with windows compilers) when
831    we build the native win32 version with the system
832    calls LoadLibrary/GetProcAddress.

957    Tag: blume-20030926-ppautoload
958    Description:
959    
960    I modified the read-eval-print loop so that the autoloader gets
961    invoked whenever the prettyprinter tries to look up a symbol that
962    is not currently defined in the toplevel environment but which
963    appears in CM's autoload registry.  As a result, we see far fewer of
964    those ?.Foo.Bar.xxx names in the prettyprinter's output.
965    
966    In addition to this I tried to clean up some pieces of the Basis
967    implementation (e.g., Socket, Word8Array) in order to prevent other
968    instances of these ?.Foo.Bar.xxx names from being printed.
969    
970    The mechanism that picks names for types still needs some work, though.
971    (Right now it seems that if there is a type A.t which is defined to
972    be B.u, but B is unavailable at toplevel, then A.t gets printed as
973    "?.B.u" although the perhaps more sensible solution would be to use
974    "A.t" in this case.  In other words, the prettyprinter should follow
975    a chain of DEFtycs not farther than there are corresponding toplevel
976    names in the current environment.)

982    Description:
983    
984    Another installer tweak:  All the ML code for the installer is now
985    compiled during CMB.make and put into a little library called
986    $smlnj/installer.cm.  The installation then simply invokes
987    
988       sml -m $smlnj/installer.cm
989    
990    and everything happens automagically.
991    
992    Win32:  ML code senses value of environment variable SMLNJ_HOME.
993    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
994            and BINDIR.
995    
996    The new scheme guarantees that the ML code responsible for the installation
997    is in sync with the APIs of the main system.  Also, the installer is
998    somewhat faster because the installer script is precompiled.

1006    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
1007    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
1008    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
1009    implementations of non-blocking operations from CML's Socket
1010    structure.

1016    Description:
1017    
1018    1. Fixed SOCKET API and implementation to match Basis spec.
1019       This required changing the internal representation of sockets to one
1020       that remembers (for each socket file descriptor) whether it is currently
1021       blocking or non-blocking.  This state is maintained lazily (i.e., a system
1022       call is made only if the state actually needs to change).
1023    
1024    2. OS-specific details of sockets were moved into separate files, thus
1025       making it possible to unify the bulk of the socket implementations
1026       between Unix and Win32.
1027    
1028    3. CML's socket API changed accordingly.
1029       (Note that we need to remove non-blocking functions from this API
1030       since they are redundant in the case of CML!)
1031    
1032    4. CML's socket implementation now makes use of non-blocking functions
1033       provided by Basis, thus removing all OS-dependent code from this part
1034       of CML.
1035    
1036    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

1149    Description:
1150    
1151    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
1152    Modified config/install.bat to take advantage of it.  Also modified
1153    config/install.sh (and called it config/new-install.sh) to take advantage
1154    of it on Unix systems.  (The SML code is (supposed to be) platform-
1155    independent.)
1156    
1157    The installer can now install everything under Win32
1158    as well as under *nix as long as it compiles.
1159    
1160    Other changes:
1161    
1162      - made CML compile again under Win32
1163      - made eXene compile under Win32 (by providing a fake structure UnixSock
1164        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
1165      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
1166        same as type int;  under Win32 it isn't
1167      - fixed some slice-related problems in the win32-specific parts of CML
1168      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
1169        (under Win32, the volume name is case-insensitive, and the
1170        OS.Path code compares volume names for equality)

1187    Description:
1188    
1189      1. Changed interface to vectors and arrays in Basis to match
1190         (draft) Basis spec.
1191      2. Added signatures and implementations of slices according to
1192         Basis spec.
1193      3. Edited source code throughout the system to make it compile again
1194         under 1. and 2.  (In some cases code had to be added to have it
1195         match the new signatures.)
1196      4. MLRISC should be backward-compatible: the copies of the originals
1197         of files that needed to change under 3. were retained, the .cm files
1198         check the compiler version number and use old versions when
1199         appropriate.
1200      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
1201         dirstream -> string option (in accordance with Basis spec).
1202      6. When generating code that counts lines, ml-lex used function
1203         CharVector.foldli, taking advantage of its old interface.
1204         This has been replaced with the corresponding code from
1205         CharVectorSlice.  (html-lex must be re-lexed!)
1206      7. BitArray in smlnj-lib/Util has been extended/modified to match the
1207         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
1208      8. Removed temporary additions (fromInternal, toInternal) from the
1209         (now obsolete) IntInf in smlnj-lib/Util.
1210      9. Cleaned up structure Byte.
1211     10. Added localOffset, scan, and fromString to Date (according to spec).
1212         Cleaned/corrected implementation of Date.
1213         (Still need to check for correctness; implement better canonicalizeDate.)
1214     11. Added "scan" to signature IEEE_REAL.
1215     12. Some improvements to IntInf [in particular: efficiency-hack for
1216         mod and rem when second operand is 2 (for parity checks).]
1217     13. Changed representation of type Time.time, using a single IntInf.int
1218         value counting microseconds.  This considerably simplified the
1219         implementation of structure Time.  We now support negative time
1220         values; scan and fromString handle signs.
1221     14. Functor PrimIO now takes two additional arguments (VectorSlice and
1222         ArraySlice).

1228    Description:
1229    
1230    This is a major update which comes with a version number bump
1231    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
1232    and an implementation of IntInf in the Basis.
1233    
1234    There are a fairly large number of related changes and updates throughout
1235    the system:
1236    
1237    Basis:
1238            - Implemented IntInf.
1239            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
1240            - Added some missing Real64 operations, most notably Real.toLargeInt.
1241            - Added FixedInt as a synonym for Int32.
1242    
1243    compiler:
1244            * Added support for a built-in intinf type.
1245              - literals
1246              - pattern matching
1247              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
1248              - overloading on literals and operations
1249    
1250            This required adding a primitive type intinf, some additional
1251            primops, and implementations for several non-trivial intinf
1252            operations in Core.  (The intinf type is completely abstract
1253            to the compiler; all operations get delegated back to the Core.)
1254    
1255            * Intinf equality is handled by polyequal.  However, the compiler
1256            does not print its usual warning in this case (since polyequal
1257            is the right thing to do there).
1258    
1259            * Improved the organization of structure InlineT.
1260    
1261            * A word about conversion primops:
1262            If conversions involving intinf do not cancel out during
1263            CPS contract, then the compiler must insert calls to Core functions.
1264            Since all core access must be resolved already during the FLINT
1265            translate phase, it would be too late a the time of CPS contract
1266            to add new Core calls.  For this reason, conversion primops
1267            for intinf carry two arguments:  1. the numeric argument that
1268            they are supposed to convert, and 2. the Core function that
1269            can help with this conversion if necessary.  If CPS contract
1270            eliminates a primop, then the associated Core function becomes
1271            dead and goes away.  Intinf conversion primops that do not get
1272            eliminated by CPS contract get rewritten into calls of their
1273            core functions by a separate, new phase.
1274    
1275    interactive system:
1276            - Control.Print.intinfDepth controls max length of intinf constants
1277            being printed. (Analogous to Control.Print.stringDepth.)
1278            - Cleanup in printutil and pputil: got rid of unused stuff and
1279            duplicates; replaced some of the code with code that makes better
1280            use of library functionality.
1281    
1282    CM:
1283            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
1284            are no longer silent.
1285    
1286    CKIT:
1287            Fixed mismatched uses of Int32 and LargeInt.  I always decided
1288            in favor of LargeInt -- which is now the same as IntInf.
1289            CKIT-knowledgable people should check whether this is what's
1290            intended and otherwise change things back to using Int32 or
1291            FixedInt.
1292    
1293    Throughout the code:
1294            Started using IntInf.int literals and built-in operations
1295            (e.g., comparison with 0) where this seems appropriate.

1317    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
1318    
1319        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
1320    
1321    This patch restores SML/NJ's ability to run under win32.  There are a
1322    number of changes, including fixes for several bugs that had gone
1323    unnoticed until now:
1324    
1325      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
1326        trying to run the win32 version from within cygwin.)
1327    
1328      - There are a number of simple .bat scripts that substitute for their
1329        corresponding Unix shell-scripts.  (See below.)
1330    
1331      - The internals of ml-build have been modified slightly.  The main
1332        difference is that instead of calling ".link-sml" (or link-sml.bat)
1333        using OS.Process.system, the ML process delegates this task back
1334        to the script.  Otherwise problems arise in mixed environments such
1335        as Cygwin where scripts look and work like Unix scripts, but
1336        where OS.Process.system cannot run them.
1337    
1338      - In CM, the srcpath pickler used native pathname syntax -- which
1339        is incorrect in the case of cross-compilation.  The new pickle format
1340        is independent of platform-specific naming conventions.
1341    
1342      - Path configuration files (such as lib/pathconfig) can now choose
1343        between native and standard syntax.  Placing a line of the form
1344    
1345            standard!
1346    
1347        into the file causes all subsequent paths to be interpreted using
1348        CM standard pathname syntax (= Unix conventions); a line
1349    
1350            native!
1351    
1352        switches back to native style.  This was needed so that
1353        path config files can be written portably, see src/system/pathconfig.
1354    
1355      - Runtime system:
1356    
1357          - win32-filesys.c:  get_file_time and set_file_time now
1358            access modification time, not creation time.
1359    
1360          - I/O code made aware of new array representation.
1361    
1362          - Bug fixes in X86.prim.masm.
1363    
1364       - src/system/makeml made aware of win32. (For use under cygwin
1365            and other Unix-environments for windows.)
1366    
1367       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
1368         which caused BinIO.inputAll to fail consistently.
1369    
1370    .bat scripts:
1371    
1372       Windows .bat scripts assume that SMLNJ_HOME is defined.
1373    
1374       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
1375         applications (sml, ml-yacc, ml-lex).
1376       - ml-build.bat: analogous to ml-build.
1377       - config\install.bat:  Analogous to config/install.sh.  This requires
1378         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
1379         (nmake etc. must be on the path, and vcvars32 must have been run.)
1380         Moreover, sources for ml-lex and ml-yacc need to exist under src,
1381         and the bootfile hierarchy must have been unpacked under
1382         sml.boot.x86-win32.
1383         The script is very primitive and does a poor job at error checking.
1384         It only installs the base system, ml-lex, and ml-yacc.  No other
1385         libraries are being installed (i.e., you get only those that
1386         are part of the compiler.)
1387       - link-sml.bat:  analogous to .link-sml, but not currently used
1388    
1389    Unrelated bug fixes:
1390    
1391      - ml-nlffigen now exports structures ST_* corresponding to incomplete
1392        types.
1393      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
1394        otherwise.)
