19    Description:
20    
21    Added C_UNION to c-calls/c-types.sml and updated the machinery
22    (ml-nlffigen, cproto.sml) that conveys C function interface
23    information to the code generator.
24    
25    However, the actual architecture-specific implementation of function
26    arguments and results that are C unions is still not implemented.

34        Added these instructions to the PowerPC architecture:
35        LBZU(X), LHZU(X), LWZU(X),
36        STWU(X), STFDU, STFSU
37    
38        etc...
39    
40        Note: I haven't added their instruction encoding into the description.

58    Description:
59    
60    - use paramAlloc to report c-calls with too many arguments
61      (for PPC version where parameter area is pre-allocated)
62    - added ccall_maxargspace to machspec (to implement the above)
63    - made "make" commend in CM's "make" tool configurable
64    - added option (default: on) for passing the name of the SML/NJ's "bin"
65      directory to "make"; the call looks like this:
66    
67         make <options> SMLNJ_BINDIR=<dir> <target>
68    
69      This can be used by the Makefile to, e.g., pick the "right" version
70      of ml-nlffigen.
71    - minor code tweaks

76    Tag: blume-110_46_1-macosx-nlffi
77    Description:
78    
79    NLFFI under Mac OS X now working (sort of).  This is largely untested,
80    though.
81    
82    Note:  1. You have to make a new, clean build of the runtime system.
83           2. There are new BOOTFILES, you have to use them!
84              (Doing the bootstrap process yourself would be *very* painful!
85               If you absolutely have to do it, build the system under
86               a different architecture and then cross-compile.)
87    
88    Version bumped to 110.46.1 to account for runtime data format changes.

94    Description:
95    
96    Changed the implementation of structure Unix so that the same stream
97    is returned every time one of the {text,bin}{In,Out}streamOf functions
98    is invoked on the same proc.  This is not what the spec currently
99    says -- although IMO it arguably should.  (See discussion below.)

112    Tag: blume-20040617-timer-unix
113    Description:
114    
115    Changed the interface of structures Timer and Unix to match the most
116    recent Basis spec.
117    
118    In the case of Unix there still seems to be an open/weird issue:
119    
120       The {text,bin}{In,Out}streamOf functions are supposed to create
121       fresh streams whenever they are called -- as opposed to have them
122       return the same stream every time.  This design is supposed to
123       prevent space leaks caused by proc values hanging on to streams.
124    
125       The reap function, on the other hand, is supposed to close the
126       streams.  This cannot be done without having a handle on the
127       stream in proc after all...
128    
129    I took the liberty to implement the following stopgap solution:
130    
131      The proc value hangs on to the most recently created stream(s).
132      Reap closes those.  If either or both of the two streams hadn't
133      been created at all yet, then reap will close the corresponding
134      file descriptors directly.
135    
136    PS: I don't understand the original space leak argument anymore.  If
137    a proc hangs on to the imperative stream, then I/O operations on those
138    will advance the state of the cached stream and avoid the space leak.

151    Tag: blume-20040525-group-owner
152    Description:
153    
154    CM now ignores (but still accepts) the "owner" information in group
155    descriptions.  The owner of a group is its next enclosing
156    library. Each group must have a unique owner.  (There is a virtual
157    "toplevel" library that owns groups which are not nested within a real
158    library.)  Previously, each group had to explicitly declare its owner,
159    and CM would check that such a declaration is correct.  The new scheme
160    is to have CM check that for each group there is precisely one owning
161    library.
162    
163    The advantage of the new scheme is that the programmer no longer needs
164    to maintain the somewhat annoying owner information.  The downside is
165    that CM cannot enforce the ownership rule across multiple runs of
166    CM.make.  Fortunately, enclosing the same group in two different
167    libraries A and B which are not part of the same program does not
168    cause real problems.

173    Tag: blume-20040520-win32
174    Description:
175    
176    Made the win32 version work again.  (Strangely, a misplaced comma had
177    slipped into win32-process.c which prevented the runtime from being
178    compiled correctly.)
179    
180    Also, included a minor addition to ml-build.bat analogous to what was
181    done in blume-20040519-ml-build.

186    Tag: blume-20040519-ml-build
187    Description:
188    
189    Arranged for ml-build to clean up after itself a little bit better.
190    The script generates a temporary SML source file and compiles it using
191    CM, so CM generates metadata (GUID, SKEL, objectfile) for it.  It now
192    gets rid of those at the end, so they don't accumulate under .cm.
193    
194    This required a minor change to install.sh because the name of the
195    metadata directory (default: .cm) is actually configurable at
196    installation time.

210    Tag: blume-20040511-win32sock
211    Description:
212    
213    Added previously missing support for many socket-related functions
214    under win32.  Thanks to David Hansel <hansel@reactive-systems.com>
215    for the voluminous patch!
216    
217    (I have not tested this patch under win32 yet.)
218    
219    Here is David's e-mail:
220    
221    Hi,
222    
223    Attached to this email you find a diff against sml/nj 110.45
224    that will enable socket support under Windows.
225    
226    To apply the patch (using unix or cygwin)
227    1) gunzip runtime.diff.gz
228    2) "cd" into "src/runtime" in the source tree of a fresh
229       110.45 installation.
230    3) patch -p 1 < [your/path/to]runtime.diff
231    
232    The code compiles fine but has NOT yet been extensively tested.
233    I only ran a few tests for basic socket client functionality
234    (which worked fine).  Especially the functions that use ioctl
235    are not tested at all and might not work (see below).
236    
237    I implemented this since we want to move to a newer version of sml/nj
238    but need socket support in order to use it.  This is the first time I
239    even had a look at the sml/nj source,  so please review my changes
240    before making this part of the distribution!  Here are a few issues
241    that I think might be better for someone to solve who is more
242    familiar with the sml/nj source (and socket programming):
243    
244    - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
245      exception since I could not figure out what the windows equivalent
246      of these functions is
247    
248    - In sockets-osdep.h there are a some #include statements that are
249      only used in a few files that include sockets-osdep.h
250    
251    - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
252      does not process its return value since I don't know how to
253      report an error upwards.
254    
255    - It would probably be good to have a call to WSACleanup() when
256      the library is unloaded (if there is such a possibility).
257      Otherwise I think Windows will take care of this automatically
258      when the process finishes.
259    
260    - I used ioctlsocket() as a replacement for ioctl() but I have
261      no idea if that is actually the proper replacement on Windows.
262    
263    - All these issues are marked in the code by "FIXME" comments.
264    
265    We use sml/nj extensively in our products and are quite happy
266    with it.  I hope this contribution will help you.
267    
268    Keep up the good work!
269

303    Description:
304    
305    The installer now honors the "src-smlnj" target again, although its meaning
306    has changed from "all sources required for the compiler" to "all sources
307    the installer knows about".  In other words, if you enable "src-smlnj"
308    in the "targets" file, then the installer will pull in sources for
309    everything.  (Notice that this refers to source code only.  Compiled
310    code is still only installed for modules that were requested explicitly
311    or which are required for other modules that were requested explicitly.)

344    Tag: leunga-20040319-cygwin-nlffi
345    Description:
346    
347    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
348    of SML/NJ.  The problem is that
349    
350       lib = dlopen(NULL, ...)
351       f   = dlsym(lib, "malloc");
352    
353    does not work on Windows unless we explicitly export symbols
354    such as 'malloc' during linking.  We fixed this by explicitly
355    exporting the required symbols with the magic gcc incantation:
356    
357        -Wl,--export-all cygwin.def
358    
359    where cygwin.def is a file containing all the symbols that
360    we wish to export.
361    
362    I suspect this is a Windows problem and we'll have to
363    do the same (somehow with windows compilers) when
364    we build the native win32 version with the system
365    calls LoadLibrary/GetProcAddress.

434    
435    Eliminated the "dont_move_libraries" directive in config/targets.
436    (The mechanism was broken and could not be fixed easily.  Moreover,
437    there does not seem to be any reason not to move all libraries into
438    lib during installation.  I originally implemented this directive as a
439    backward-compatibility feature when I first introduced the new CM.
440    Now that things have been stable for a long time and going back to the
441    old CM is not an option, there is no reason to keep it around.)

465    
466    1. Added openVector, nullRd, and nullWr to PRIM_IO.
467    2. Improved .bat files (for Win32 port) to make things work under Win95.
468       (thanks to Aaron S. Hawley for this one)

491    Description:
492    
493    I modified the read-eval-print loop so that the autoloader gets
494    invoked whenever the prettyprinter tries to look up a symbol that
495    is not currently defined in the toplevel environment but which
496    appears in CM's autoload registry.  As a result, we see far fewer of
497    those ?.Foo.Bar.xxx names in the prettyprinter's output.
498    
499    In addition to this I tried to clean up some pieces of the Basis
500    implementation (e.g., Socket, Word8Array) in order to prevent other
501    instances of these ?.Foo.Bar.xxx names from being printed.
502    
503    The mechanism that picks names for types still needs some work, though.
504    (Right now it seems that if there is a type A.t which is defined to
505    be B.u, but B is unavailable at toplevel, then A.t gets printed as
506    "?.B.u" although the perhaps more sensible solution would be to use
507    "A.t" in this case.  In other words, the prettyprinter should follow
508    a chain of DEFtycs not farther than there are corresponding toplevel
509    names in the current environment.)

515    Description:
516    
517    Another installer tweak:  All the ML code for the installer is now
518    compiled during CMB.make and put into a little library called
519    $smlnj/installer.cm.  The installation then simply invokes
520    
521       sml -m $smlnj/installer.cm
522    
523    and everything happens automagically.
524    
525    Win32:  ML code senses value of environment variable SMLNJ_HOME.
526    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
527            and BINDIR.
528    
529    The new scheme guarantees that the ML code responsible for the installation
530    is in sync with the APIs of the main system.  Also, the installer is
531    somewhat faster because the installer script is precompiled.

537    Description:
538    
539    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
540    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
541    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
542    implementations of non-blocking operations from CML's Socket
543    structure.

549    Description:
550    
551    1. Fixed SOCKET API and implementation to match Basis spec.
552       This required changing the internal representation of sockets to one
553       that remembers (for each socket file descriptor) whether it is currently
554       blocking or non-blocking.  This state is maintained lazily (i.e., a system
555       call is made only if the state actually needs to change).
556    
557    2. OS-specific details of sockets were moved into separate files, thus
558       making it possible to unify the bulk of the socket implementations
559       between Unix and Win32.
560    
561    3. CML's socket API changed accordingly.
562       (Note that we need to remove non-blocking functions from this API
563       since they are redundant in the case of CML!)
564    
565    4. CML's socket implementation now makes use of non-blocking functions
566       provided by Basis, thus removing all OS-dependent code from this part
567       of CML.
568    
569    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.
