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

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

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

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

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

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

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

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

265    
266    Minor bugfix in config/libinstall (set anchor with path to
267    standalone tool after installing it, otherwise libraries that
268    need ml-lex or ml-yacc won't compile the first time the installer

294    Tag: blume-20030909-installer
295    Description:
296    
297    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
298    Modified config/install.bat to take advantage of it.  Also modified
299    config/install.sh (and called it config/new-install.sh) to take advantage
300    of it on Unix systems.  (The SML code is (supposed to be) platform-
301    independent.)
302    
303    The installer can now install everything under Win32
304    as well as under *nix as long as it compiles.
305    
306    Other changes:
307    
308      - made CML compile again under Win32
309      - made eXene compile under Win32 (by providing a fake structure UnixSock
310        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
311      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
312        same as type int;  under Win32 it isn't
313      - fixed some slice-related problems in the win32-specific parts of CML
314      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
315        (under Win32, the volume name is case-insensitive, and the
316        OS.Path code compares volume names for equality)

322    Description:
323    
324    Made Win32 version of OS.FileSys.fullPath return current directory
325    when given an empty string.  This is what the spec says, and incidentally,
326    CM depends on it.  (CM otherwise goes into an infinite loop in certain
327    cases when presented with the name of a non-existing .cm file.)

332    Tag: blume-20030905-slices-etc
333    Description:
334    
335      1. Changed interface to vectors and arrays in Basis to match
336         (draft) Basis spec.
337      2. Added signatures and implementations of slices according to
338         Basis spec.
339      3. Edited source code throughout the system to make it compile again
340         under 1. and 2.  (In some cases code had to be added to have it
341         match the new signatures.)
342      4. MLRISC should be backward-compatible: the copies of the originals
343         of files that needed to change under 3. were retained, the .cm files
344         check the compiler version number and use old versions when
345         appropriate.
346      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
347         dirstream -> string option (in accordance with Basis spec).
348      6. When generating code that counts lines, ml-lex used function
349         CharVector.foldli, taking advantage of its old interface.
350         This has been replaced with the corresponding code from
351         CharVectorSlice.  (html-lex must be re-lexed!)
352      7. BitArray in smlnj-lib/Util has been extended/modified to match the
353         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
354      8. Removed temporary additions (fromInternal, toInternal) from the
355         (now obsolete) IntInf in smlnj-lib/Util.
356      9. Cleaned up structure Byte.
357     10. Added localOffset, scan, and fromString to Date (according to spec).
358         Cleaned/corrected implementation of Date.
359         (Still need to check for correctness; implement better canonicalizeDate.)
360     11. Added "scan" to signature IEEE_REAL.
361     12. Some improvements to IntInf [in particular: efficiency-hack for
362         mod and rem when second operand is 2 (for parity checks).]
363     13. Changed representation of type Time.time, using a single IntInf.int
364         value counting microseconds.  This considerably simplified the
365         implementation of structure Time.  We now support negative time
366         values; scan and fromString handle signs.
367     14. Functor PrimIO now takes two additional arguments (VectorSlice and
368         ArraySlice).
