19    Description:
20    
21    - Stripped down the versiontool: It now only handles the version number.
22      The date string is generated at bootstrap time (during makeml).
23    
24    - In a previous commit, fixed a minor issue with how polyequal is being
25      translated.  In particular, the code now "looks through" abstractions.
26      This results in slightly fewer polyEqual warnings and hopefully slightly
27      more efficient code.  Important examples for where this matters are
28      the new int64 and word64 types.

34    Description:
35    
36    Structure Int64 fully hooked in.  (The implementation is not very
37    efficient, though.)

43    Description:
44    
45    All the pieces of Word64 are now there, with the exception of the
46    conversions from and to LargeWord. (Eventually these need to be identities,
47    but for the time being they don't even make sense because LargeWord is
48    32-bit wide.)
49    
50    Also started to add similar support for Int64, but major pieces of that
51    are still missing.

56    Tag: blume-20041111-word64
57    Description:
58    
59    Structure Word64 is now (almost) complete, word literals and patterns
60    seem to work.  There are a few odd pieces missing.  In particular,
61    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
62    at the moment.
63    
64    Making Word64 official would mean that LargeWord becomes Word64.  But
65    this requires extreme care because most word-word conversions have to
66    go through LargeWord, so making a mistake means loss of efficiency or
67    worse.  Eventually there will be a solution similar to (but actually
68    simpler than) what I did with IntInf.

76    More 64-bit hacking (but still not even half-way there yet).
77    Also, some assorted improvements to the handling of 8-bit words.

92    Description:
93    
94    New working version (110.50).  NEW BOOTFILES!
95    
96                 =====================
97    
98    Also:
99    
100      - Changend config/srcarchiveurl from a file just
101        containing the URL string into a file containing
102        shell script code.  The code has access to the $VERSION variable.
103      - Made corresponding changes to config/install.sh and config/unpack.
104      - Default contents of config/srcarchiveurl uses $VERSION and
105        normally does not have to be edited to reflect a version change.
106    
107      (As a result, a version change can be done by just editing
108       config/version, the rest is now automatic.)

123    Description:
124    
125    This is the HISTORY entry for two earlier commits, both concerning
126    the x86 c-calls code in MLRISC:
127    
128      - added a missing LOAD in the code that deals with struct arguments
129      - made sure the caller does not add the wrong number of bytes to the
130        stack pointer after a call of a function returning a struct
131        (the callee already pops the implicit argument which points to
132         the space reserved for the result)

148    Tag: blume-20041020-standalone-backtrace
149    Description:
150    
151    Added a mechanism for getting back-trace information from standalone
152    programs.  Here is how it works:
153    
154       1. The part of the program from which you want to get backtrace
155          information (usually the whole program) should be wrapped with
156          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
157          main program could be modified from something like
158    
159             fun main (pgm, args) = ...
160    
161         to
162    
163            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
164    
165       2. To be able to access BackTrace.monitor, you have to add
166          library $smlnj-tdp/plugins.cm to the .cm file that contains your
167          main function.
168    
169       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
170          CM might have created in the past for your project).
171    
172       4. Build the system using this command line:
173    
174             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
175                      myprog.cm MyProg.main myprog
176    
177          instead of the usual
178    
179             ml-build myprog.cm MyProg.main myprog
180    
181    I changed a library name:
182    
183       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
184    
185    New libraries:
186    
187       $smlnj-tdp/back-trace.cm
188          -- when loaded causes the back-trace plugin to be installed
189       $smlnj-tdp/coverage.cm
190          -- when loaded causes the coverage plugin to be installed

199    
200    Eliminated group owner specs from .cm files throughout the source tree.

205    Tag: blume-20041015-coverage
206    Description:
207    
208    * Test coverage tool added!
209    * Further reorganization of tracing-, debugging-, and profiling support:
210    
211        - moved original BTImp -- now called BackTrace -- into a separate
212          library called $/trace-debug-profile.cm
213        - eliminated all mentions of BTrace from SMLofNJ.Internals
214        - only the instrumentation mechanism is now left in the compiler proper
215        - BackTrace module is a plugin which is NOT plugged in by default
216        - Coverage module is another such plugin
217    
218    To get the benefits of any of these plugin modules, the code in
219    question must be compiled with tdp instrumentation turned on.  This
220    can be done by setting SMLofNJ.Internals.TDP.mode to true.
221    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
222    
223    Plugins are selected at link time.  (Pre-compiled instrumented code
224    can be re-loaded with different plugins in effect.)  When an
225    instrumented module is linked, whatever plugins are at that time
226    enabled will come into effect for that module.
227    
228    To enable the back-trace plugin, load library $/trace-debug-profile.cm
229    and invoke BackTrace.install() (e.g., from the interactive prompt).
230    To enable the coverage plugin, load the same library and invoke
231    Coverage.install().
232    
233    Back-traces are generated automatically on uncaught exceptions and
234    when the code in question explicitly invokes BackTrace.trigger().
235    
236    Coverage (and execution frequency-) information must be queried
237    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

243    Description:

245    Snapshot of a significant overhaul of how the trace/debug/profile support
246    is hooked into the system (specifically: Core and SMLofNJ.Internals).

252    Description:
253    
254    Some rationalization of names:
255    
256       structure BTrace -> structure TDPInstrument
257       etc.
258    
259    This is is preparation of using the original back-trace
260    instrumentation for other purposes.  "TDP" stands for
261    Trace/Debug/Profile.
262    
263    The control flag controlling whether instrumentation is on or off is now
264    registered under a different name, so instead of running sml as
265    
266     sml -Cinstrument.btrace-mode=true
267    
268    one has to say
269    
270     sml -Ctdp.instrument=true

276    Description:
277    
278    Made some minor modifications to elabcore.sml to have source regions
279    be propagated more tightly -- resulting in better (i.e., smaller)
280    regions being reported in error- and debug messages.

285    Tag: blume-20041008-cmkw
286    Description:
287    
288    Fixed handling of keywords in .cm files: After seeing "is" the lexer
289    treats subsequent occurrences of "group", "library", "source", "is",
290    "*", and "-" as ordinary identifiers rather than keywords.
291    
292    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
293    is supposed to accept a tool argument called "source", but this did
294    not work because of the clash with the keyword.

300    Description:
301    
302    Assorted cleanup work:
303    
304      - got rid of intstrmap in favor of using the library's
305        hash table implementation
306      - threw out most of the pathnames stuff, as it was not used anyway
307      - simplified tokentable implementation
308      - fixed some minor spelling errors

326    Description:
327    
328    Added hack to make slave mode work in the presence of the version
329    tool.  (Still, since the master does two passes over the code for
330    CMB.make, the release number gets bumped twice when slaves are
331    attached.  I don't know if this is worth fixing...)

337    Description:
338    
339    * Moved the "version" magic into its own little library under
340      src/system/smlnj/internal.  This avoids expensive reconstruction of
341      a stable src/compiler/core.cm.
342    
343    * At the same time, structure CompilerVersion is now known as
344      structure SMLNJVersion.
345    
346    * Arranged for the version tool to NOT kick in when rebuilding the system
347      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
348      Also, loading the versiontool does not work when rebuilding the system
349      because CM is not properly initialized at that time.

354    Tag: blume-20040929-autoversion
355    Description:
356    
357    Implemented some CM magic to have
358        file src/compiler/TopLevel/main/version.sml
359    generated automagically.
360    The version is taken from two files: config/version and config/release.
361    The first is expected to contain a two-part version number such as 110.49.
362    The second should contain a single number, but it may be missing.
363    
364    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
365    time the version tool is loaded (which is the first time you say CMB.make),
366    then the tool will increment the value stored in config/release every
367    time CMB.make is invoked.
368    
369    The binfile format is now insensitive to anything beyond the first
370    two components of a version number, so bumping the release does not render
371    binfiles incompatible.  Auto-bumping can be used to keep track of versions
372    during development without invalidating existing binfiles.
373    
374    In any case, every CMB.make updates the date information in version.sml.
375    (This is the date that is printed in the banner.)

388    Tag: blume-20040927-controls
389    Description:
390    
391    Added two pieces of functionality to the Controls interface:
392    
393    1.   val save'restore: 'a control -> unit -> unit
394    
395       grabs the current value of the control in stage 1 and restores it
396       in stage 2.
397    
398    2.   val set' : 'a control * 'a -> unit -> unit
399    
400       stores the given value into the control in stage 2 (i.e., delayed)
401       but does all error checking in stage 1.
402       (This is for string controls that need to do parse their argument --
403        something that might fail.  In some cases, notably in CM, one
404        already knows the intended argument but wants to delay the actual
405        assignment until a time when error recovery would be more difficult.)
406    
407    Changed the handling of controls in tool arguments to classes "sml" and
408    "lazysml":
409       - use Controls.save'restore as a more robust way of restoring the
410         old value (in particular: without having to re-parse the string)
411       - use controls to handle the "overload" keyword in the init group
412         (I believe this change actually fixes a long-standing obscure bug.)

417    Tag: blume-20040927-lazysml
418    Description:
419    
420    Added a new tool class called "lazysml" to CM's tool chest.  The only
421    difference to "sml" is that compilation is done with Control.lazysml
422    set to true.  A source of class "lazysml" is automatically recognized
423    by a file name suffix of ".lml".
424    
425    In addition to the above feature, the original class "sml" now also
426    supports a tool argument "lazy" which has the same effect.  As a
427    result, the following three lines are equivalent:
428    
429        foo.sml : lazysml
430        foo.sml : sml (lazy)
431        foo.sml (lazy)
432    
433    The setting goes into effect both during parsing and during
434    compilation.  The original setting is restored right after parsing and
435    after compilation, respectively.
436    
437    In addition to all the above, there is also a general mechanism to set
438    ANY of the "controls" that are available at the command line via
439    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
440    apply as well. (In fact, "lazy" is implemented as a special case of
441    the general mechanism.)
442    
443    The .cm file syntax uses a new keyword tool argument called "with".
444    There are several ways of indicating the desired settings:
445    
446        foo.sml (with:parser.quotations=true)
447        foo.sml (with:(name:parser.quotations value:true))
448        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
449        foo.sml (with:(name1=value1 name2=value2 ...))
450        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
451    
452        etc.
453    
454    Another possible abbreviation is to leave out the =v or value:v part
455    if the name refers to a boolean control (in which case the value is
456    taken to be true).  Thus, one could get lazy sml also by saying:
457    
458        foo.sml (with:parser.lazy-keyword=true)
459        foo.sml (with:parser.lazy-keyword)
460        foo.sml (with:(name:parser.lazy-keyword value:true))
461        foo.sml (with:(name:parser.lazy-keyword))

813    Description:
814    
815    Changed the interface of structures Timer and Unix to match the most
816    recent Basis spec.
817    
818    In the case of Unix there still seems to be an open/weird issue:
819    
820       The {text,bin}{In,Out}streamOf functions are supposed to create
821       fresh streams whenever they are called -- as opposed to have them
822       return the same stream every time.  This design is supposed to
823       prevent space leaks caused by proc values hanging on to streams.
824    
825       The reap function, on the other hand, is supposed to close the
826       streams.  This cannot be done without having a handle on the
827       stream in proc after all...
828    
829    I took the liberty to implement the following stopgap solution:
830    
831      The proc value hangs on to the most recently created stream(s).
832      Reap closes those.  If either or both of the two streams hadn't
833      been created at all yet, then reap will close the corresponding
834      file descriptors directly.
835    
836    PS: I don't understand the original space leak argument anymore.  If
837    a proc hangs on to the imperative stream, then I/O operations on those
838    will advance the state of the cached stream and avoid the space leak.

852    Description:
853    
854    CM now ignores (but still accepts) the "owner" information in group
855    descriptions.  The owner of a group is its next enclosing
856    library. Each group must have a unique owner.  (There is a virtual
857    "toplevel" library that owns groups which are not nested within a real
858    library.)  Previously, each group had to explicitly declare its owner,
859    and CM would check that such a declaration is correct.  The new scheme
860    is to have CM check that for each group there is precisely one owning
861    library.
862    
863    The advantage of the new scheme is that the programmer no longer needs
864    to maintain the somewhat annoying owner information.  The downside is
865    that CM cannot enforce the ownership rule across multiple runs of
866    CM.make.  Fortunately, enclosing the same group in two different
867    libraries A and B which are not part of the same program does not
868    cause real problems.

887    Description:
888    
889    Arranged for ml-build to clean up after itself a little bit better.
890    The script generates a temporary SML source file and compiles it using
891    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
892    gets rid of those at the end, so they don't accumulate under .cm.
893    
894    This required a minor change to install.sh because the name of the
895    metadata directory (default: .cm) is actually configurable at
896    installation time.

913    Added previously missing support for many socket-related functions
914    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
915    for the voluminous patch!
916    
917    (I have not tested this patch under win32 yet.)
918    
919    Here is David's e-mail:
920    
921    Hi,
922    
923    Attached to this email you find a diff against sml/nj 110.45
924    that will enable socket support under Windows.
925    
926    To apply the patch (using unix or cygwin)
927    1) gunzip runtime.diff.gz
928    2) "cd" into "src/runtime" in the source tree of a fresh
929       110.45 installation.
930    3) patch -p 1 < [your/path/to]runtime.diff
931    
932    The code compiles fine but has NOT yet been extensively tested.
933    I only ran a few tests for basic socket client functionality
934    (which worked fine).  Especially the functions that use ioctl
935    are not tested at all and might not work (see below).
936    
937    I implemented this since we want to move to a newer version of sml/nj
938    but need socket support in order to use it.  This is the first time I
939    even had a look at the sml/nj source,  so please review my changes
940    before making this part of the distribution!  Here are a few issues
941    that I think might be better for someone to solve who is more
942    familiar with the sml/nj source (and socket programming):
943    
944    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
945      exception since I could not figure out what the windows equivalent
946      of these functions is
947    
948    - In sockets-osdep.h there are a some #include statements that are
949      only used in a few files that include sockets-osdep.h
950    
951    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
952      does not process its return value since I don't know how to
953      report an error upwards.
954    
955    - It would probably be good to have a call to WSACleanup() when
956      the library is unloaded (if there is such a possibility).
957      Otherwise I think Windows will take care of this automatically
958      when the process finishes.
959    
960    - I used ioctlsocket() as a replacement for ioctl() but I have
961      no idea if that is actually the proper replacement on Windows.
962    
963    - All these issues are marked in the code by "FIXME" comments.
964    
965    We use sml/nj extensively in our products and are quite happy
966    with it.  I hope this contribution will help you.
967    
968    Keep up the good work!
969

1005    The installer now honors the "src-smlnj" target again, although its meaning
1006    has changed from "all sources required for the compiler" to "all sources
1007    the installer knows about".  In other words, if you enable "src-smlnj"
1008    in the "targets" file, then the installer will pull in sources for
1009    everything.  (Notice that this refers to source code only.  Compiled
1010    code is still only installed for modules that were requested explicitly
1011    or which are required for other modules that were requested explicitly.)

1045    Description:
1046    
1047    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
1048    of SML/NJ.  The problem is that
1049    
1050       lib = dlopen(NULL, ...)
1051       f   = dlsym(lib, "malloc");
1052    
1053    does not work on Windows unless we explicitly export symbols
1054    such as 'malloc' during linking.  We fixed this by explicitly
1055    exporting the required symbols with the magic gcc incantation:
1056    
1057        -Wl,--export-all cygwin.def
1058    
1059    where cygwin.def is a file containing all the symbols that
1060    we wish to export.
1061    
1062    I suspect this is a Windows problem and we'll have to
1063    do the same (somehow with windows compilers) when
1064    we build the native win32 version with the system
1065    calls LoadLibrary/GetProcAddress.

1136    (The mechanism was broken and could not be fixed easily.  Moreover,
1137    there does not seem to be any reason not to move all libraries into
1138    lib during installation.  I originally implemented this directive as a
1139    backward-compatibility feature when I first introduced the new CM.
1140    Now that things have been stable for a long time and going back to the
1141    old CM is not an option, there is no reason to keep it around.)

1191    Description:
1192    
1193    I modified the read-eval-print loop so that the autoloader gets
1194    invoked whenever the prettyprinter tries to look up a symbol that
1195    is not currently defined in the toplevel environment but which
1196    appears in CM's autoload registry.  As a result, we see far fewer of
1197    those ?.Foo.Bar.xxx names in the prettyprinter's output.
1198    
1199    In addition to this I tried to clean up some pieces of the Basis
1200    implementation (e.g., Socket, Word8Array) in order to prevent other
1201    instances of these ?.Foo.Bar.xxx names from being printed.
1202    
1203    The mechanism that picks names for types still needs some work, though.
1204    (Right now it seems that if there is a type A.t which is defined to
1205    be B.u, but B is unavailable at toplevel, then A.t gets printed as
1206    "?.B.u" although the perhaps more sensible solution would be to use
1207    "A.t" in this case.  In other words, the prettyprinter should follow
1208    a chain of DEFtycs not farther than there are corresponding toplevel
1209    names in the current environment.)

1215    Description:
1216    
1217    Another installer tweak:  All the ML code for the installer is now
1218    compiled during CMB.make and put into a little library called
1219    $smlnj/installer.cm.  The installation then simply invokes
1220    
1221       sml -m $smlnj/installer.cm
1222    
1223    and everything happens automagically.
1224    
1225    Win32:  ML code senses value of environment variable SMLNJ_HOME.
1226    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
1227            and BINDIR.
1228    
1229    The new scheme guarantees that the ML code responsible for the installation
1230    is in sync with the APIs of the main system.  Also, the installer is
1231    somewhat faster because the installer script is precompiled.

1242    implementations of non-blocking operations from CML's Socket
1243    structure.

1248    Tag: blume-20030924-sockets
1249    Description:
1250    
1251    1. Fixed SOCKET API and implementation to match Basis spec.
1252       This required changing the internal representation of sockets to one
1253       that remembers (for each socket file descriptor) whether it is currently
1254       blocking or non-blocking.  This state is maintained lazily (i.e., a system
1255       call is made only if the state actually needs to change).
1256    
1257    2. OS-specific details of sockets were moved into separate files, thus
1258       making it possible to unify the bulk of the socket implementations
1259       between Unix and Win32.
1260    
1261    3. CML's socket API changed accordingly.
1262       (Note that we need to remove non-blocking functions from this API
1263       since they are redundant in the case of CML!)
1264    
1265    4. CML's socket implementation now makes use of non-blocking functions
1266       provided by Basis, thus removing all OS-dependent code from this part
1267       of CML.
1268    
1269    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.
