44    Tag: blume-20031104-move-libraries
45    Description:
46    
47    Eliminated the "dont_move_libraries" directive in config/targets.
48    (The mechanism was broken and could not be fixed easily.  Moreover,
49    there does not seem to be any reason not to move all libraries into
50    lib during installation.  I originally implemented this directive as a
51    backward-compatibility feature when I first introduced the new CM.
52    Now that things have been stable for a long time and going back to the
53    old CM is not an option, there is no reason to keep it around.)

102    Tag: blume-20030926-ppautoload
103    Description:
104    
105    I modified the read-eval-print loop so that the autoloader gets
106    invoked whenever the prettyprinter tries to look up a symbol that
107    is not currently defined in the toplevel environment but which
108    appears in CM's autoload registry.  As a result, we see far fewer of
109    those ?.Foo.Bar.xxx names in the prettyprinter's output.
110    
111    In addition to this I tried to clean up some pieces of the Basis
112    implementation (e.g., Socket, Word8Array) in order to prevent other
113    instances of these ?.Foo.Bar.xxx names from being printed.
114    
115    The mechanism that picks names for types still needs some work, though.
116    (Right now it seems that if there is a type A.t which is defined to
117    be B.u, but B is unavailable at toplevel, then A.t gets printed as
118    "?.B.u" although the perhaps more sensible solution would be to use
119    "A.t" in this case.  In other words, the prettyprinter should follow
120    a chain of DEFtycs not farther than there are corresponding toplevel
121    names in the current environment.)

126    Tag: blume-20030924-installer
127    Description:
128    
129    Another installer tweak:  All the ML code for the installer is now
130    compiled during CMB.make and put into a little library called
131    $smlnj/installer.cm.  The installation then simply invokes
132    
133       sml -m $smlnj/installer.cm
134    
135    and everything happens automagically.
136    
137    Win32:  ML code senses value of environment variable SMLNJ_HOME.
138    Unix:   ML code senses values of environment variables ROOT, CONFIGDIR,
139            and BINDIR.
140    
141    The new scheme guarantees that the ML code responsible for the installation
142    is in sync with the APIs of the main system.  Also, the installer is
143    somewhat faster because the installer script is precompiled.

148    Tag: blume-20030924-synsock
149    Description:
150    
151    Added a signature SYNCHRONOUS_SOCKET to basis.cm.  This is like SOCKET
152    but excludes all non-blocking operations.  Defined SOCKET (in Basis)
153    and CML_SOCKET in terms of SYNCHRONOUS_SOCKET.  Removed superfluous
154    implementations of non-blocking operations from CML's Socket
155    structure.

160    Tag: blume-20030924-sockets
161    Description:
162    
163    1. Fixed SOCKET API and implementation to match Basis spec.
164       This required changing the internal representation of sockets to one
165       that remembers (for each socket file descriptor) whether it is currently
166       blocking or non-blocking.  This state is maintained lazily (i.e., a system
167       call is made only if the state actually needs to change).
168    
169    2. OS-specific details of sockets were moved into separate files, thus
170       making it possible to unify the bulk of the socket implementations
171       between Unix and Win32.
172    
173    3. CML's socket API changed accordingly.
174       (Note that we need to remove non-blocking functions from this API
175       since they are redundant in the case of CML!)
176    
177    4. CML's socket implementation now makes use of non-blocking functions
178       provided by Basis, thus removing all OS-dependent code from this part
179       of CML.
180    
181    5. Changed Real64.precision from 52 to 53.  Minor cleanup in Real64 code.

197    Tag: blume-20030919-cmdir
198    Description:
199    
200    1. new-install.sh -> install.sh
201    2. changed default CM "metadata" directory name to ".cm" (instead of "CM")
202    3. tweaked installer so that another name instead of .cm can be chosen
203       at install time (by setting the CM_DIR_ARC environment variable
204       during installation); once installation is complete, the name is
205       fixed

222    Description:
223    
224    1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
225       this seems to be controversial at the moment) and used those in
226       Posix.ProcEnv.times.
227    
228    2. Added Time.{from,to}Nanoseconds to Time.
229    
230    3. Improved Real.{from,to}LargeInt by avoiding needless calculations.
231       For example, fromLargeInt never needs to look at more than 3 "big
232       digits" to get its 53 bits of precision.

237    Tag: blume-20030917-real32-slices
238    Description:
239    
240    Added an entry to the primitive environment
241    (compiler/Semant/statenv/prim.sml) for int32->real64 conversion and
242    added code to compiler/CodeGen/main/mlriscGen.sml to implement it.
243    
244    Removed some of the "magic" constants in real64.sml and replaced them
245    with code that generates these values from their corresponding
246    integer counterparts.
247    
248    Made all(?) the slice-related changes to the Basis and made everything
249    compile again...
