60    Tag: blume-20050518-installer
61    Description:
62    
63    Added support scripts for Mac OS X PackageMaker and modified
64    config/install.sh so that it supports re-dumping a heap image
65    after customization.

78    Tag: blume-20050516-redump-heap
79    Description:
80    
81    Added mechanism for re-creating a heap file for the interactive system
82    after configuration variables have been changed.
83    
84       CM.redump_heap : string -> unit
85    
86    This is much like SMLofNJ.exportML, but starting from the resulting
87    heap does not return to the caller of CM.redump_heap but
88    restarts the interactive system from scratch.  The original call of
89    CM.redump_heap does not return but ends the interactive session.
90    Thus, CM.redump_heap is a lot like SMLofNJ.exportFn.
91    
92    Internally, redump_heap winds the dynamic execution context back to
93    the point where the original heap image was created and re-executes
94    the heap image generation code in the boot code.
95

99    Tag: blume-20050509-word64
100    Description:
101    
102    Added a hack to the existing hack known as Word64 to make fromString
103    behave correctly.  I am still not sure whether Word64.scan will work
104    as specified with respect to the interaction of radix and prefix.
105

109    Tag: leunga-20050504-checkgc
110    Description:
111    
112    Added a gc protocol checking phase.  This phase is enabled with
113    the flag "check-gc".  "debug-check-gc" turns on the verbose mode.
114

118    Tag: blume-20050504-intinf
119    Description:
120    
121    Fixed a bug in the implementation of div and mod for IntInf.
122    Thanks to Neophytos Michael for reporting the problem.
123

127    Tag: blume-20050504-join
128    Description:
129    
130    Added a "join" combinator to the ParserComb module in smlnj-lib.cm.

135    Tag: blume-20050228-mVar
136    Description:
137    
138    Fixed serious bug (brown paper bag variety) in new implementation of
139    structure Atom in CML.  (I had accidentally used a mailbox instead of
140    an mvar, leaving the door open for races.)

153    Tag: blume-20050225-susp
154    Description:
155    
156    Brought back SMLofNJ.Susp.  The underlying suspension type is the one
157    implemented in Core -- which means that it is the same as the one used
158    by the lazy extension.

163    Tag: blume-20050224-cml-atom
164    Description:
165    
166    Simpler and at the same time more general implementation of structure
167    Atom in CML.
168

170    Name: Matthias Blume (blume (at) tti - c (dot) org)
171    Date: 2005/02/15 17:35:00 CST
172    Tag: blume-20050215-tools
173    Description:
174    
175    Created new "tools" directory under "src" and moved "TraceDebugProf"
176    there.
177    
178    ----------------------------------------------------------------------

180    Date: 2005/02/10 17:55:00 CST
181    Tag: blume-20050210-longlong
182    Description:
183    
184    Implemented "long long" arguments and results for NLFFI.  (Only the
185    PPC/MacOS implementation is complete, the other backends still need to
186    be updated.)
187

190    Date: 2005/01/24 17:40:00 CST
191    Tag: blume-20050124-mlyacc
192    Description:
193    
194    Minor cleanup in ML-Yacc rule printing mechanism.  This should fix a
195    problem with certain "as" patterns which previously got rendered
196    using incorrect syntax.
197

201    Tag: blume-20050118-profile
202    Description:
203    
204    Made time profiling code (interrupt handler) in runtime system aware
205    of new array representation.
206    
207    ----------------------------------------------------------------------
208    Name: Matthias Blume (blume (at) tti - c (dot) org)
209    Date: 2005/01/14 18:00:00 CST
210    Tag: blume-20050114-heap2exec
211    Description:
212    
213    Implemented new (but still experimental) heap2exec facility.  This is
214    tested under Mac OS X and should work under Linux (will test shortly).
215    It will probably also work on the Sparc (will test some time later).
216    
217      - removed old "HACKED_STANDALONE" hack from runtime
218    
219    To be able to test this, uncomment the request for "heap2asm" in
220    config/targets prior to installation.  (Notice that this is different
221    from "heap2exec" mentioned below.  Not a typo.)
222    
223    To perform an actual test, run the command
224    
225       $ bin/heap2exec heapfile execfile
226    
227    (You can put heap2exec on your shell's path.)
228    
229    For example, run
230    
231      $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
232    
233    This will create a standalone executable called "mly" which you can
234    then invoke directly as a command.

241    
242    fixed off-by-one error in ML_STRING macro (globals.c)
243

247    Tag: blume-20041223-santa
248    Description:
249    
250    Made ml-build script "smarter" (but only very little).
251    
252    ----------------------------------------------------------------------
253    Name: Matthias Blume (blume (at) tti - c (dot) org)
254    Date: 2004/12/21 15:05:00 CST
255    Tag: blume-20041221-longlong
256    Description:
257    
258    * Implemented access to signed and unsigned long long data in NLFFI.
259    (The parameter-passing part of the picture has not complete. But
260    data structure access seems to work.)
261    
262    * Fixed CM's incorrect assumption that the PPC is little-endian.
263      (On the Mac, it is big-endian.  And that's currently our only
264      PPC platform.)
265

269    Tag: blume-20041221-memory
270    Description:
271    
272    Some cleanup in the $c/memory.cm library: separated some concerns by
273    moving allocation code and memory access code each into their own
274    files.
275

279    Tag: leunga-20041217-cygwin-smlnj-home
280    Description:
281    
282        The Unix I/O library of SML/NJ on cygwin does not understand
283    Windows style pathname, so problems arise when SMLNJ_HOME is set
284    to a Windows style pathname.  _run-sml now converts SMLNJ_HOME
285    to a POSIX pathname on cygwin.

292    
293    Last-minute changes incorporated into 110.52.  Release tag moved.
294    
295    The changes:
296       - HashString.hashString' -> HashString.hashSubstring
297       - bug fix in UnivariateStats

303    Description:
304    
305    - HashString.hashString' -> HashString.hashSubstring
306    - corresponding changes in atom.sml
307    - "de-compressed" (aka. un-obfuscated) code for UnivariateStats and
308      added some comments

328    Date: 2004/12/14 17:30:00 CST
329    Tag: blume-20041214-spaces
330    Description:
331    
332    Hacked some of the scripts (in particular: the installer) to cope with
333    spaces in filenames a bit better.  But beware: the current "solution"
334    is likely still full of bugs and inherently incomplete.  (We need to
335    do away with those shell scripts for a comprehensive solution.)

350    
351    Added two simple but potentially useful statistics modules to SML/NJ Library.
352    (See CHANGES file there.)

358    Description:
359    
360    smlnj-lib:
361    
362      Added function HashString.hashString' for substrings.
363      Hand-inlined CharVector.foldl into HashString (for speed).
364      Modified implementation of structure Atom to avoid extracting
365      strings from substrings unless necessary.
366      (Also see CHANGES file for smlnj-lib.)

371    Tag: blume-20041124-cml
372    Description:
373    
374    Made sure CML compiles when Position = Int64.

379    Tag: blume-20041124-position
380    Description:
381    
382    The compiler can now be compiled in a mode that makes structure Position
383    equal to Int64.  The default, however, is unchanged (Position = Int31)
384    for the time being.
385    
386    To enable 64-bit positions, use the following procedure:
387    
388    1. Start sml
389    2. Autoload $smlnj/cmb.cm (if not already autoloaded)
390    3. Type
391          #set (CMB.symval "USE_64_BIT_POSITIONS") (SOME 1);
392    4. Run CMB.make() as usual.
393    
394    This is barely tested.  The only test so far was a little SML program
395    counting the number of characters in an 8-gigabyte file by
396    reading it character-by-character.  That test was successful.
397    
398    In support of 64-bit positions, a number of new functions have been
399    added to the runtime system.

439    Tag: blume-20041113-versiontool
440    Description:
441    
442    - Stripped down the versiontool: It now only handles the version number.
443      The date string is generated at bootstrap time (during makeml).
444    
445    - In a previous commit, fixed a minor issue with how polyequal is being
446      translated.  In particular, the code now "looks through" abstractions.
447      This results in slightly fewer polyEqual warnings and hopefully slightly
448      more efficient code.  Important examples for where this matters are
449      the new int64 and word64 types.

463    Tag: blume-20041111-more64
464    Description:
465    
466    All the pieces of Word64 are now there, with the exception of the
467    conversions from and to LargeWord. (Eventually these need to be identities,
468    but for the time being they don't even make sense because LargeWord is
469    32-bit wide.)
470

472    are still missing.

478    Description:
479    
480    Structure Word64 is now (almost) complete, word literals and patterns
481    seem to work.  There are a few odd pieces missing.  In particular,
482    I didn't do the {from,to}LargeWord parts because LargeWord is still Word32
483    at the moment.
484    
485    Making Word64 official would mean that LargeWord becomes Word64.  But
486    this requires extreme care because most word-word conversions have to
487    go through LargeWord, so making a mistake means loss of efficiency or
488    worse.  Eventually there will be a solution similar to (but actually
489    simpler than) what I did with IntInf.

524      - Made corresponding changes to config/install.sh and config/unpack.
525      - Default contents of config/srcarchiveurl uses $VERSION and
526        normally does not have to be edited to reflect a version change.
527    
528      (As a result, a version change can be done by just editing
529       config/version, the rest is now automatic.)

569    Tag: blume-20041020-standalone-backtrace
570    Description:
571    
572    Added a mechanism for getting back-trace information from standalone
573    programs.  Here is how it works:
574    
575       1. The part of the program from which you want to get backtrace
576          information (usually the whole program) should be wrapped with
577          BackTrace.monitor.  This is a (unit->'a)->'a function, and your
578          main program could be modified from something like
579    
580             fun main (pgm, args) = ...
581    
582         to
583    
584            fun main (pgm, args) = BackTrace.monitor (fn () => ...)
585    
586       2. To be able to access BackTrace.monitor, you have to add
587          library $smlnj-tdp/plugins.cm to the .cm file that contains your
588          main function.
589    
590       3. Remove all compiled code (i.e., all the .cm/ subdirectories that
591          CM might have created in the past for your project).
592    
593       4. Build the system using this command line:
594    
595             ml-build -Ctdp.instrument=true \$smlnj-tdp/back-trace.cm \
596                      myprog.cm MyProg.main myprog
597    
598          instead of the usual
599    
600             ml-build myprog.cm MyProg.main myprog
601    
602    I changed a library name:
603    
604       $/trace-debug-profile.cm --> $smlnj-tdp/plugins.cm
605    
606    New libraries:
607    
608       $smlnj-tdp/back-trace.cm
609          -- when loaded causes the back-trace plugin to be installed
610       $smlnj-tdp/coverage.cm
611          -- when loaded causes the coverage plugin to be installed

627    Description:
628    
629    * Test coverage tool added!
630    * Further reorganization of tracing-, debugging-, and profiling support:
631    
632        - moved original BTImp -- now called BackTrace -- into a separate
633          library called $/trace-debug-profile.cm
634        - eliminated all mentions of BTrace from SMLofNJ.Internals
635        - only the instrumentation mechanism is now left in the compiler proper
636        - BackTrace module is a plugin which is NOT plugged in by default
637        - Coverage module is another such plugin
638    
639    To get the benefits of any of these plugin modules, the code in
640    question must be compiled with tdp instrumentation turned on.  This
641    can be done by setting SMLofNJ.Internals.TDP.mode to true.
642    (The ref cell is also controlled via the -Ctdp.instrument=... switch.)
643    
644    Plugins are selected at link time.  (Pre-compiled instrumented code
645    can be re-loaded with different plugins in effect.)  When an
646    instrumented module is linked, whatever plugins are at that time
647    enabled will come into effect for that module.
648    
649    To enable the back-trace plugin, load library $/trace-debug-profile.cm
650    and invoke BackTrace.install() (e.g., from the interactive prompt).
651    To enable the coverage plugin, load the same library and invoke
652    Coverage.install().
653    
654    Back-traces are generated automatically on uncaught exceptions and
655    when the code in question explicitly invokes BackTrace.trigger().
656    
657    Coverage (and execution frequency-) information must be queried
658    explicitly by calling Coverage.not_covered and Coverage.hot_spots.

680    This is is preparation of using the original back-trace
681    instrumentation for other purposes.  "TDP" stands for
682    Trace/Debug/Profile.
683    
684    The control flag controlling whether instrumentation is on or off is now
685    registered under a different name, so instead of running sml as
686    
687     sml -Cinstrument.btrace-mode=true
688    
689    one has to say

768      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.

776    Description:
777    
778    Implemented some CM magic to have
779        file src/compiler/TopLevel/main/version.sml
780    generated automagically.
781    The version is taken from two files: config/version and config/release.
782    The first is expected to contain a two-part version number such as 110.49.
783    The second should contain a single number, but it may be missing.
784    
785    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
786    time the version tool is loaded (which is the first time you say CMB.make),
787    then the tool will increment the value stored in config/release every
788    time CMB.make is invoked.
789    
790    The binfile format is now insensitive to anything beyond the first
791    two components of a version number, so bumping the release does not render
792    binfiles incompatible.  Auto-bumping can be used to keep track of versions
793    during development without invalidating existing binfiles.
794    
795    In any case, every CMB.make updates the date information in version.sml.
796    (This is the date that is printed in the banner.)

810    Description:
811    
812    Added two pieces of functionality to the Controls interface:
813    
814    1.   val save'restore: 'a control -> unit -> unit
815    
816       grabs the current value of the control in stage 1 and restores it
817       in stage 2.
818    
819    2.   val set' : 'a control * 'a -> unit -> unit
820    
821       stores the given value into the control in stage 2 (i.e., delayed)
822       but does all error checking in stage 1.
823       (This is for string controls that need to do parse their argument --
824        something that might fail.  In some cases, notably in CM, one
825        already knows the intended argument but wants to delay the actual
826        assignment until a time when error recovery would be more difficult.)
827    
828    Changed the handling of controls in tool arguments to classes "sml" and
829    "lazysml":
830       - use Controls.save'restore as a more robust way of restoring the
831         old value (in particular: without having to re-parse the string)
832       - use controls to handle the "overload" keyword in the init group
833         (I believe this change actually fixes a long-standing obscure bug.)

838    Tag: blume-20040927-lazysml
839    Description:
840    
841    Added a new tool class called "lazysml" to CM's tool chest.  The only
842    difference to "sml" is that compilation is done with Control.lazysml
843    set to true.  A source of class "lazysml" is automatically recognized
844    by a file name suffix of ".lml".
845    
846    In addition to the above feature, the original class "sml" now also
847    supports a tool argument "lazy" which has the same effect.  As a
848    result, the following three lines are equivalent:
849    
850        foo.sml : lazysml
851        foo.sml : sml (lazy)
852        foo.sml (lazy)
853    
854    The setting goes into effect both during parsing and during
855    compilation.  The original setting is restored right after parsing and
856    after compilation, respectively.
857    
858    In addition to all the above, there is also a general mechanism to set
859    ANY of the "controls" that are available at the command line via
860    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
861    apply as well. (In fact, "lazy" is implemented as a special case of
862    the general mechanism.)
863    
864    The .cm file syntax uses a new keyword tool argument called "with".
865    There are several ways of indicating the desired settings:
866    
867        foo.sml (with:parser.quotations=true)
868        foo.sml (with:(name:parser.quotations value:true))
869        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
870        foo.sml (with:(name1=value1 name2=value2 ...))
871        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
872    
873        etc.
874    
875    Another possible abbreviation is to leave out the =v or value:v part
876    if the name refers to a boolean control (in which case the value is
877    taken to be true).  Thus, one could get lazy sml also by saying:
878    
879        foo.sml (with:parser.lazy-keyword=true)
880        foo.sml (with:parser.lazy-keyword)
881        foo.sml (with:(name:parser.lazy-keyword value:true))
882        foo.sml (with:(name:parser.lazy-keyword))

1181    - use paramAlloc to report c-calls with too many arguments

1183    - added ccall_maxargspace to machspec (to implement the above)
1184    - made "make" commend in CM's "make" tool configurable
1185    - added option (default: on) for passing the name of the SML/NJ's "bin"

1187    
1188         make <options> SMLNJ_BINDIR=<dir> <target>

1202    
1203    Note:  1. You have to make a new, clean build of the runtime system.
1204           2. There are new BOOTFILES, you have to use them!
1205              (Doing the bootstrap process yourself would be *very* painful!
1206               If you absolutely have to do it, build the system under
1207               a different architecture and then cross-compile.)

1234    Description:
1235    
1236    Changed the interface of structures Timer and Unix to match the most
1237    recent Basis spec.
1238    
1239    In the case of Unix there still seems to be an open/weird issue:
1240    
1241       The {text,bin}{In,Out}streamOf functions are supposed to create
1242       fresh streams whenever they are called -- as opposed to have them
1243       return the same stream every time.  This design is supposed to
1244       prevent space leaks caused by proc values hanging on to streams.
1245    
1246       The reap function, on the other hand, is supposed to close the
1247       streams.  This cannot be done without having a handle on the
1248       stream in proc after all...
1249    
1250    I took the liberty to implement the following stopgap solution:
1251    
1252      The proc value hangs on to the most recently created stream(s).
1253      Reap closes those.  If either or both of the two streams hadn't
1254      been created at all yet, then reap will close the corresponding
1255      file descriptors directly.
1256    
1257    PS: I don't understand the original space leak argument anymore.  If
1258    a proc hangs on to the imperative stream, then I/O operations on those
1259    will advance the state of the cached stream and avoid the space leak.

1273    Description:
1274    
1275    CM now ignores (but still accepts) the "owner" information in group
1276    descriptions.  The owner of a group is its next enclosing
1277    library. Each group must have a unique owner.  (There is a virtual
1278    "toplevel" library that owns groups which are not nested within a real
1279    library.)  Previously, each group had to explicitly declare its owner,
1280    and CM would check that such a declaration is correct.  The new scheme
1281    is to have CM check that for each group there is precisely one owning
1282    library.
1283    
1284    The advantage of the new scheme is that the programmer no longer needs
1285    to maintain the somewhat annoying owner information.  The downside is
1286    that CM cannot enforce the ownership rule across multiple runs of
1287    CM.make.  Fortunately, enclosing the same group in two different
1288    libraries A and B which are not part of the same program does not
1289    cause real problems.
