28    
29    1. Added openVector, nullRd, and nullWr to PRIM_IO.
30    2. Improved .bat files (for Win32 port) to make things work under Win95.

53    Tag: blume-20030926-ppautoload
54    Description:
55    
56    I modified the read-eval-print loop so that the autoloader gets
57    invoked whenever the prettyprinter tries to look up a symbol that
58    is not currently defined in the toplevel environment but which
59    appears in CM's autoload registry.  As a result, we see far fewer of
60    those ?.Foo.Bar.xxx names in the prettyprinter's output.
61    
62    In addition to this I tried to clean up some pieces of the Basis
63    implementation (e.g., Socket, Word8Array) in order to prevent other
64    instances of these ?.Foo.Bar.xxx names from being printed.
65    
66    The mechanism that picks names for types still needs some work, though.
67    (Right now it seems that if there is a type A.t which is defined to
68    be B.u, but B is unavailable at toplevel, then A.t gets printed as
69    "?.B.u" although the perhaps more sensible solution would be to use
70    "A.t" in this case.  In other words, the prettyprinter should follow
71    a chain of DEFtycs not farther than there are corresponding toplevel
72    names in the current environment.)

77    Tag: blume-20030924-installer
78    Description:
79    
80    Another installer tweak:  All the ML code for the installer is now
81    compiled during CMB.make and put into a little library called
82    $smlnj/installer.cm.  The installation then simply invokes
83    
84       sml -m $smlnj/installer.cm
85    
86    and everything happens automagically.
87    
88    Win32:  ML code senses value of environment variable SMLNJ_HOME.
89    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
90            and BINDIR.
91    
92    The new scheme guarantees that the ML code responsible for the installation
93    is in sync with the APIs of the main system.  Also, the installer is
94    somewhat faster because the installer script is precompiled.

100    Description:
101    
102    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
103    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
104    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
105    implementations of non-blocking operations from CML's Socket
106    structure.

112    Description:
113    
114    1. Fixed SOCKET API and implementation to match Basis spec.
115       This required changing the internal representation of sockets to one
116       that remembers (for each socket file descriptor) whether it is currently
117       blocking or non-blocking.  This state is maintained lazily (i.e., a system
118       call is made only if the state actually needs to change).
119    
120    2. OS-specific details of sockets were moved into separate files, thus
121       making it possible to unify the bulk of the socket implementations
122       between Unix and Win32.
123    
124    3. CML's socket API changed accordingly.
125       (Note that we need to remove non-blocking functions from this API
126       since they are redundant in the case of CML!)
127    
128    4. CML's socket implementation now makes use of non-blocking functions
129       provided by Basis, thus removing all OS-dependent code from this part
130       of CML.
131    
132    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

148    Tag: blume-20030919-cmdir
149    Description:
150    
151    1. new-install.sh -> install.sh
152    2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
153    3. tweaked installer so that another name instead of .cm can be chosen
154       at install time (by setting the CM_DIR_ARC environment variable
155       during installation); once installation is complete, the name is
156       fixed

173    Description:
174    
175    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
176       this seems to be controversial at the moment) and used those in
177       Posix.ProcEnv.times.
178    
179    2. Added Time.{from,to}Nanoseconds to Time.
180    
181    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
182       For example, fromLargeInt never needs to look at more than 3 "big
183       digits" to get its 53 bits of precision.

189    Description:
190    
191    Added an entry to the primitive environment
192    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
193    added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
194    
195    Removed some of the "magic" constants in real64.sml and replaced them
196    with code that generates these values from their corresponding
197    integer counterparts.
198    
199    Made all(?) the slice-related changes to the Basis and made everything
200    compile again...
