37    Description:
38    
39       Added a patch to _arch-n-opsys to enable the Cygwin runtime.
40    The Cygwin runtime is turned on by setting the environment
41    variable SMLNJ_CYGWIN_RUNTIME to 1.

55    Description:
56    
57    Upon request by Johannes Joemann:
58    
59    - improved ML code of installer to fall back to coping when renaming
60      fails (i.e., when source and target are on different file systems);
61      the code compiles but has yet to be tested in anger
62    - removed mlrisc from list of default targets (config/targets)

110    Description:
111    
112    Bug fix from Carl Hauser:
113    
114    single_source_shortest_paths in dijkstra.sml was observed to get wrong
115    answers (by comparing to single_source_shortest_paths in bellman-ford.sml).
116    
117    The problem is that following the expression A.update(dist,s,Num.zero)
118    it is necessary to update the priority queue using Q.decreaseWeight(Q,s).

123    Tag: blume-20040806-cmdline
124    Description:
125    
126    Fiddled with handling of command-line options:
127    
128      * sml now quits after processing the command line
129        if -H, -S, -h<n>, or -s<n> appears as the last
130        command-line argument
131      * a new option -q terminates the session when encountered on
132        the command line; subsequent arguments will be ignored
133      * bug fixes: short (erroneous) arguments are no longer ignored
134        completely

140    Description:
141    
142      - Added minimal IBM assembly syntax support for PowerPC.
143    
144      - Cygwin: manually changed the file cygwin.def.  Some exported symbols have
145        been altered in the runtime.  We need an automatic way to keep the file
146        in sync.

160    Description:
161    
162    Added low-level support for choosing C calling conventions by
163    twiddling the type of rawccall.  (See

170    Description:
171    
172    Backed out of change to win32-filesys.c.  The earlier patch to
173    get_file_time caused CM to produce files with the wrong time stamp.

189    Description:
190    
191    Gearing up towards 110.47...
192    
193    - various minor bugfixes to ml-nlffigen
194    - a beginning of a manual for nlffi
195    
196    - eliminated 'export name=value' in config/install.sh as this does
197      not work with certain versions of /bin/sh
198      (Thanks to David King at Motorola for catching this.)
199    
200    - several bugfixes provided or suggested by David Hansel at Reactive Systems:
201      - added a test for tm==NULL to gmtime.c and localtime.c
202      - applied patch for incorrect GetFileTime under win32
203      - toSeconds -> toMilliseconds in Win32/win32-process.sml

210    
211    - Fixed minor issue in ml-nlffigen: Now generate structure T_foo
212      for a typedef to an incomplete type, but leave out the "typ" member.
213      (This is just for consistency.)
214    - Started to produce what is supposed to become better (i.e., comprehensive)
215      documentation of what ml-nlffigen does and produces.

221    Description:
222    
223    Added C_UNION to c-calls/c-types.sml and updated the machinery
224    (ml-nlffigen, cproto.sml) that conveys C function interface
225    information to the code generator.
226    
227    However, the actual architecture-specific implementation of function
228    arguments and results that are C unions is still not implemented.

238        STWU(X), STFDU, STFSU
239

252    
253       A (untested) rewrite of loop-structure.sml.  The old version
254    is completely broken.

259    Tag: blume-20040713-nlffi
260    Description:
261    
262    - use paramAlloc to report c-calls with too many arguments
263      (for PPC version where parameter area is pre-allocated)
264    - added ccall_maxargspace to machspec (to implement the above)
265    - made "make" commend in CM's "make" tool configurable
266    - added option (default: on) for passing the name of the SML/NJ's "bin"
267      directory to "make"; the call looks like this:
268    
269         make <options> SMLNJ_BINDIR=<dir> <target>
270    
271      This can be used by the Makefile to, e.g., pick the "right" version
272      of ml-nlffigen.
273    - minor code tweaks

279    Description:
280    
281    NLFFI under Mac OS X now working (sort of).  This is largely untested,
282    though.
283    
284    Note:  1. You have to make a new, clean build of the runtime system.
285           2. There are new BOOTFILES, you have to use them!
286              (Doing the bootstrap process yourself would be *very* painful!
287               If you absolutely have to do it, build the system under
288               a different architecture and then cross-compile.)
289    
290    Version bumped to 110.46.1 to account for runtime data format changes.

295    Tag: blume-20040618-unix
296    Description:
297    
298    Changed the implementation of structure Unix so that the same stream
299    is returned every time one of the {text,bin}{In,Out}streamOf functions
300    is invoked on the same proc.  This is not what the spec currently
301    says -- although IMO it arguably should.  (See discussion below.)

314    Tag: blume-20040617-timer-unix
315    Description:
316    
317    Changed the interface of structures Timer and Unix to match the most
318    recent Basis spec.
319    
320    In the case of Unix there still seems to be an open/weird issue:
321    
322       The {text,bin}{In,Out}streamOf functions are supposed to create
323       fresh streams whenever they are called -- as opposed to have them
324       return the same stream every time.  This design is supposed to
325       prevent space leaks caused by proc values hanging on to streams.
326    
327       The reap function, on the other hand, is supposed to close the
328       streams.  This cannot be done without having a handle on the
329       stream in proc after all...
330    
331    I took the liberty to implement the following stopgap solution:
332    
333      The proc value hangs on to the most recently created stream(s).
334      Reap closes those.  If either or both of the two streams hadn't
335      been created at all yet, then reap will close the corresponding
336      file descriptors directly.
337    
338    PS: I don't understand the original space leak argument anymore.  If
339    a proc hangs on to the imperative stream, then I/O operations on those
340    will advance the state of the cached stream and avoid the space leak.

353    Tag: blume-20040525-group-owner
354    Description:
355    
356    CM now ignores (but still accepts) the "owner" information in group
357    descriptions.  The owner of a group is its next enclosing
358    library. Each group must have a unique owner.  (There is a virtual
359    "toplevel" library that owns groups which are not nested within a real
360    library.)  Previously, each group had to explicitly declare its owner,
361    and CM would check that such a declaration is correct.  The new scheme
362    is to have CM check that for each group there is precisely one owning
363    library.
364    
365    The advantage of the new scheme is that the programmer no longer needs
366    to maintain the somewhat annoying owner information.  The downside is
367    that CM cannot enforce the ownership rule across multiple runs of
368    CM.make.  Fortunately, enclosing the same group in two different
369    libraries A and B which are not part of the same program does not
370    cause real problems.

376    Description:
377    
378    Made the win32 version work again.  (Strangely, a misplaced comma had
379    slipped into win32-process.c which prevented the runtime from being
380    compiled correctly.)
381    
382    Also, included a minor addition to ml-build.bat analogous to what was
383    done in blume-20040519-ml-build.

389    Description:
390    
391    Arranged for ml-build to clean up after itself a little bit better.
392    The script generates a temporary SML source file and compiles it using
393    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
394    gets rid of those at the end, so they don't accumulate under .cm.
395    
396    This required a minor change to install.sh because the name of the
397    metadata directory (default: .cm) is actually configurable at
398    installation time.

413    Description:
414    
415    Added previously missing support for many socket-related functions
416    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
417    for the voluminous patch!
418    
419    (I have not tested this patch under win32 yet.)
420    
421    Here is David's e-mail:
422    
423    Hi,
424    
425    Attached to this email you find a diff against sml/nj 110.45
426    that will enable socket support under Windows.
427    
428    To apply the patch (using unix or cygwin)
429    1) gunzip runtime.diff.gz
430    2) "cd" into "src/runtime" in the source tree of a fresh
431       110.45 installation.
432    3) patch -p 1 < [your/path/to]runtime.diff
433    
434    The code compiles fine but has NOT yet been extensively tested.
435    I only ran a few tests for basic socket client functionality
436    (which worked fine).  Especially the functions that use ioctl
437    are not tested at all and might not work (see below).
438    
439    I implemented this since we want to move to a newer version of sml/nj
440    but need socket support in order to use it.  This is the first time I
441    even had a look at the sml/nj source,  so please review my changes
442    before making this part of the distribution!  Here are a few issues
443    that I think might be better for someone to solve who is more
444    familiar with the sml/nj source (and socket programming):
445    
446    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
447      exception since I could not figure out what the windows equivalent
448      of these functions is
449    
450    - In sockets-osdep.h there are a some #include statements that are
451      only used in a few files that include sockets-osdep.h
452    
453    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
454      does not process its return value since I don't know how to
455      report an error upwards.

457    - It would probably be good to have a call to WSACleanup() when
458      the library is unloaded (if there is such a possibility).
459      Otherwise I think Windows will take care of this automatically
460      when the process finishes.
461    
462    - I used ioctlsocket() as a replacement for ioctl() but I have
463      no idea if that is actually the proper replacement on Windows.
464    
465    - All these issues are marked in the code by "FIXME" comments.
466    
467    We use sml/nj extensively in our products and are quite happy
468    with it.  I hope this contribution will help you.
469    
470    Keep up the good work!

505    Description:
506    
507    The installer now honors the "src-smlnj" target again, although its meaning
508    has changed from "all sources required for the compiler" to "all sources
509    the installer knows about".  In other words, if you enable "src-smlnj"
510    in the "targets" file, then the installer will pull in sources for
511    everything.  (Notice that this refers to source code only.  Compiled
512    code is still only installed for modules that were requested explicitly
513    or which are required for other modules that were requested explicitly.)

546    Tag: leunga-20040319-cygwin-nlffi
547    Description:
548    
549    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
550    of SML/NJ.  The problem is that
551    
552       lib = dlopen(NULL, ...)
553       f   = dlsym(lib, "malloc");
554    
555    does not work on Windows unless we explicitly export symbols
556    such as 'malloc' during linking.  We fixed this by explicitly
557    exporting the required symbols with the magic gcc incantation:
558    
559        -Wl,--export-all cygwin.def
560    
561    where cygwin.def is a file containing all the symbols that
562    we wish to export.
563    
564    I suspect this is a Windows problem and we'll have to
565    do the same (somehow with windows compilers) when
566    we build the native win32 version with the system
567    calls LoadLibrary/GetProcAddress.

635    Description:
636    
637    Eliminated the "dont_move_libraries" directive in config/targets.
638    (The mechanism was broken and could not be fixed easily.  Moreover,
639    there does not seem to be any reason not to move all libraries into
640    lib during installation.  I originally implemented this directive as a
641    backward-compatibility feature when I first introduced the new CM.
642    Now that things have been stable for a long time and going back to the
643    old CM is not an option, there is no reason to keep it around.)

692    Tag: blume-20030926-ppautoload
693    Description:
694    
695    I modified the read-eval-print loop so that the autoloader gets
696    invoked whenever the prettyprinter tries to look up a symbol that
697    is not currently defined in the toplevel environment but which
698    appears in CM's autoload registry.  As a result, we see far fewer of
699    those ?.Foo.Bar.xxx names in the prettyprinter's output.
700    
701    In addition to this I tried to clean up some pieces of the Basis
702    implementation (e.g., Socket, Word8Array) in order to prevent other
703    instances of these ?.Foo.Bar.xxx names from being printed.
704    
705    The mechanism that picks names for types still needs some work, though.
706    (Right now it seems that if there is a type A.t which is defined to
707    be B.u, but B is unavailable at toplevel, then A.t gets printed as
708    "?.B.u" although the perhaps more sensible solution would be to use
709    "A.t" in this case.  In other words, the prettyprinter should follow
710    a chain of DEFtycs not farther than there are corresponding toplevel
711    names in the current environment.)

717    Description:
718    
719    Another installer tweak:  All the ML code for the installer is now
720    compiled during CMB.make and put into a little library called
721    $smlnj/installer.cm.  The installation then simply invokes
722    
723       sml -m $smlnj/installer.cm
724    
725    and everything happens automagically.
726    
727    Win32:  ML code senses value of environment variable SMLNJ_HOME.
728    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
729            and BINDIR.
730    
731    The new scheme guarantees that the ML code responsible for the installation
732    is in sync with the APIs of the main system.  Also, the installer is
733    somewhat faster because the installer script is precompiled.
