19    Description:
20    
21    The ml-build script now terminates with a non-0 status when something
22    goes wrong.

30    Made exception Option to be the same as exception Option.Option
31    (as it should be).

36    Tag: leunga-20040319-cygwin-nlffi
37    Description:
38    
39    Fixed the runtime so that ml-nlffi-lib runs on the cygwin version
40    of SML/NJ.  The problem is that
41    
42       lib = dlopen(NULL, ...)
43       f   = dlsym(lib, "malloc");
44    
45    does not work on Windows unless we explicitly export symbols
46    such as 'malloc' during linking.  We fixed this by explicitly
47    exporting the required symbols with the magic gcc incantation:
48    
49        -Wl,--export-all cygwin.def
50    
51    where cygwin.def is a file containing all the symbols that
52    we wish to export.
53    
54    I suspect this is a Windows problem and we'll have to
55    do the same (somehow with windows compilers) when
56    we build the native win32 version with the system
57    calls LoadLibrary/GetProcAddress.

63    Description:
64    
65    Fixed problem with IntInf.fmt (sign would show up on the right instead
66    of on the left for BIN, OCT, and HEX).

72    Description:
73    
74    Fixed problem with installer script (unix only) where bin/ml-yacc and
75    friends pointed (via symlinks) to absolute locations instead of just
76    .run-sml.  This was reported by Vesa A Norrman.

124    Tag: blume-20031104-move-libraries
125    Description:
126    
127    Eliminated the "dont_move_libraries" directive in config/targets.
128    (The mechanism was broken and could not be fixed easily.  Moreover,
129    there does not seem to be any reason not to move all libraries into
130    lib during installation.  I originally implemented this directive as a
131    backward-compatibility feature when I first introduced the new CM.
132    Now that things have been stable for a long time and going back to the
133    old CM is not an option, there is no reason to keep it around.)

182    Tag: blume-20030926-ppautoload
183    Description:
184    
185    I modified the read-eval-print loop so that the autoloader gets
186    invoked whenever the prettyprinter tries to look up a symbol that
187    is not currently defined in the toplevel environment but which
188    appears in CM's autoload registry.  As a result, we see far fewer of
189    those ?.Foo.Bar.xxx names in the prettyprinter's output.
190    
191    In addition to this I tried to clean up some pieces of the Basis
192    implementation (e.g., Socket, Word8Array) in order to prevent other
193    instances of these ?.Foo.Bar.xxx names from being printed.
194    
195    The mechanism that picks names for types still needs some work, though.
196    (Right now it seems that if there is a type A.t which is defined to
197    be B.u, but B is unavailable at toplevel, then A.t gets printed as
198    "?.B.u" although the perhaps more sensible solution would be to use
199    "A.t" in this case.  In other words, the prettyprinter should follow
200    a chain of DEFtycs not farther than there are corresponding toplevel
201    names in the current environment.)

206    Tag: blume-20030924-installer
207    Description:
208    
209    Another installer tweak:  All the ML code for the installer is now
210    compiled during CMB.make and put into a little library called
211    $smlnj/installer.cm.  The installation then simply invokes
212    
213       sml -m $smlnj/installer.cm
214    
215    and everything happens automagically.
216    
217    Win32:  ML code senses value of environment variable SMLNJ_HOME.
218    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
219            and BINDIR.
220    
221    The new scheme guarantees that the ML code responsible for the installation
222    is in sync with the APIs of the main system.  Also, the installer is
223    somewhat faster because the installer script is precompiled.

228    Tag: blume-20030924-synsock
229    Description:
230    
231    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
232    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
233    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
234    implementations of non-blocking operations from CML's Socket
235    structure.

240    Tag: blume-20030924-sockets
241    Description:
242    
243    1. Fixed SOCKET API and implementation to match Basis spec.
244       This required changing the internal representation of sockets to one
245       that remembers (for each socket file descriptor) whether it is currently
246       blocking or non-blocking.  This state is maintained lazily (i.e., a system
247       call is made only if the state actually needs to change).
248    
249    2. OS-specific details of sockets were moved into separate files, thus
250       making it possible to unify the bulk of the socket implementations
251       between Unix and Win32.
252    
253    3. CML's socket API changed accordingly.
254       (Note that we need to remove non-blocking functions from this API
255       since they are redundant in the case of CML!)
256    
257    4. CML's socket implementation now makes use of non-blocking functions
258       provided by Basis, thus removing all OS-dependent code from this part
259       of CML.
260    
261    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.
