1 : jhr 3992 Standard ML of New Jersey Change Log
2 :     ====================================
3 :     The Fellowship of SML/NJ
4 : jhr 3998 {version}, {releasedate}:
5 : jhr 3992
6 : jhr 4002 This file documents changes to the Standard ML of New Jersey system since
7 :     March of 2000 (around Version 110.26). The change log primarily covers
8 :     the compiler, the compilation manager (*CM*), the *MLRISC* library, and
9 :     the runtime system. There are occasional entries about other components
10 :     (_e.g._, the *SML/NJ Library* and *ML-LPT*), but these components have
11 :     their own change logs that should be consulted.
12 :    
13 : jhr 3992 //////////////////////////////////////////////////////////////////////
14 :     This change log is in ASCII doc format. An HTML version of the
15 :     change log can be generated using the command
16 :    
17 : jhr 4049 make html
18 : jhr 3992
19 :     An entry should be made for _every_ commit to the repository.
20 :     The entries in this file will be used when creating the README
21 :     for new versions, so keep that in mind when writing the
22 :     description.
23 :    
24 :     The structure of the HISTORY is that there is a section for
25 :     each release, which starts with a section header of the form
26 :    
27 :     == Version xxx.yy; yyyy/mm/dd
28 :    
29 :     The content of a section is a list of entries. The form of an
30 :     entry should be:
31 :    
32 :     [yyy/mm/dd]::
33 :     +
34 : jhr 3995 Description ...
35 : jhr 3992 +
36 :     owner:[Your Name,URL]
37 :    
38 : jhr 3995 Note that we put "+" at the beginning of blank lines. Entries are items
39 :     in a labeled list and the "+" character keeps eveything in the same list
40 :     element.
41 :    
42 : jhr 3992 Here is a quick asciidoc cheat sheet:
43 :    
44 :     + new paragraph
45 :     *foo* bold "foo"
46 :     _foo_ italic "foo"
47 :     +foo+ teletype "foo"
48 :     http:/some.website.org/path[] URL
49 :     bugref:[123] displays as "#123" with
50 :     a link to the bug report.
51 :     owner:[name,url] displays name with URL link.
52 :    
53 : jhr 3995 Sub lists should be bracketed with lines containing just "--".
54 : jhr 3992 Bulleted list items start with a single dash or one to five
55 :     asterisks followed by some white space then some text. Numberd
56 :     list items begin one to five period characters, followed by
57 :     some white space then the item text.
58 :    
59 : jhr 3995 Literal (verbatim) blocks are delimited by
60 :     .....................
61 :     stuff
62 :     .....................
63 :    
64 : jhr 3992 Superscripts and subscripts are denoted by putting ^ (or ~)
65 :     around the text to superscripted (superscripted). For example,
66 :     the number 256 can be written as 2^8^.
67 :    
68 :     SML source code displays can be included as source blocks:
69 :    
70 :     [source,sml]
71 :     ------------
72 :     structure Foo = struct val x = 1 end
73 :     ------------
74 :    
75 :     Source code will be stylized using the pygmentize (http://pygments.org)
76 :     tool.
77 :    
78 :     More information about asciidoc can be found at http://asciidoc.org.
79 :    
80 : jhr 4002 NOTE: the original HISTORY file was converted to ASCIIDOC using a Perl
81 :     script. This script gets the basic structure for entries correct,
82 :     but there still needs to be a fair bit of editing to add ASCIIDOC
83 :     markup, fix indentation issues, nested lists, etc. Working from most
84 :     recent to oldest, I've edited back to release 110.46 (2004/06/17).

89 : jhr 3992
90 : jhr 4060 //--------------------------------------------------------------------
91 : jhr 4076 [2015/07/08]::
92 :     +
93 : jhr 4077 Added Linux 4.* kernels to the list of operating systems recognized
94 :     by the ++.arch-n-opsys++ script (fixes bug bugref:[134]).
95 : jhr 4076 +
96 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
97 :    
98 :     //--------------------------------------------------------------------
99 : jhr 4074 [2015/06/11]::
100 :     +
101 :     Added Mac OS X 10.11 (El Capitan) to the list of operating systems
102 :     recognized by the ++.arch-n-opsys++ script.
103 :     +
104 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
105 :    
106 :     //--------------------------------------------------------------------
107 : jhr 4060 [2015/05/27]::
108 :     +
109 : jhr 4062 Added support for SuccessorML lexical extensions. These can be enabled
110 :     using the command-line option ++-Cparser.succ-ml=true++ or the assignment
111 :     +
112 :     [source,sml]
113 :     ------------
114 :     Control.succML := true;
115 :     ------------
116 :     +
117 :     at the REPL. The extensions are as follows:
118 : jhr 4060 --
119 : jhr 4062 - "_" as a separator in numeric literals; __e.g.__, ++123_456++, ++0wxff_ff_ff_f3++,
120 : jhr 4060 ++123_456.1++, ...
121 :    
122 :     - end-of-line comments, which are denoted using ++(*)++. End-of-line comments
123 :     properly nest into conventional block comments. For example, the following
124 :     block comment is well formed:
125 :     +
126 :     [source,sml]
127 :     ------------
128 :     (*
129 :     fun f x = x (*) my identity function *)
130 :     *)
131 :     ------------
132 :     +
133 : jhr 4062 - binary literals for both integers and words; __e.g.__, ++0b0101_1110++, or
134 : jhr 4060 ++0wb1101++.

139 : jhr 4037 == Version 110.78; 2014/12/24
140 : jhr 4002
141 : jhr 3992 //--------------------------------------------------------------------
142 : dbm 4001 [2014/12/19]::
143 :     +
144 :     Major revision of the machinery for overloading resolution for both
145 :     operators (vars) and literals, now using a common mechanism. This fixes
146 :     bug bugref:[52] by improving the error message when an overloaded
147 : jhr 4049 operator is inconsistent with its context. Updated 23 files, including
148 : dbm 4001 major changes in +overload.sml+, +types.sml+, +unify.sml+, +elabcore.sml+,
149 :     +typesutil.sml+. The overload declaration is still used in
150 :     +pervasives.sml+, where the order of the specified instances of an
151 : jhr 4002 ordering determines the default interpretation (_i.e._, the first one).
152 : dbm 4001 +
153 :     The +SCHEME+ and +LITERAL+ forms of tyvars are replaced by a new
154 :     +OVLD+ form that tracks potential instantiations of the type of the
155 :     overloaded vars or literals.
156 :     +
157 :     owner:[David MacQueen,http://cs.uchicago.edu/~dbm]
158 :    
159 :     //--------------------------------------------------------------------
160 : jhr 4002 [2014/12/18]::
161 :     +
162 :     Moved +base/NOTES/HISTORY+ file to +doc/src/changelog/HISTORY.txt+
163 :     and converted it to http://asciidoc.org[ASCIIDOC] format. Have also
164 :     moved the +README+ files from +base/READMES+ to +doc/src/release-notes+.
165 :     These changes are part of a general effort to rationalize and improve
166 :     the documentation of the *SML/NJ* system.
167 :     +
168 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
169 :    
170 :     //--------------------------------------------------------------------
171 : jhr 3994 [2014/12/13]::
172 :     +
173 : jhr 4002 Preliminary cleanups before changes to overloading
174 :     +
175 : jhr 3994 Minor cleanup in +Elaborator/elaborate/elabcore+ (function +elabOVERLOADdec+)
176 :     and in +ElabData/types/typesutil.sml+ (function +matchScheme+). Preparing for
177 :     a new method of handling type checking of overloaded operators. [Note
178 :     that there is no reason for the options field of +OVLDvar+ to be a
179 :     reference -- it is never updated. Changing this requires corresponding
180 :     change in pickling.]
181 :     +
182 :     Also added an +etopdebugging+ flag (+ElabControl+) for debugging in
183 :     +elabtop.sml+. Modified ++elabcontrol.++{++sml++,++sig++} and
184 :     +elabtop.sml+. Also rearranged ast and absyn printing in +evalloop.sml+.

188 :     //--------------------------------------------------------------------
189 : jhr 3992 [2014/10/23]::
190 :     +
191 :     Improved error messages in *ml-ulex* for unclosed strings. Also made
192 :     documentation improvements.
193 :     +
194 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
195 :    
196 :     //--------------------------------------------------------------------
197 :     [2014/10/11]::
198 :     +
199 :     Added +-D_FILE_OFFSET_BITS=64+ flag to +x86-linux+ makefile. This flag
200 :     is necessary to avoid spurious +EOVERFLOW+ errors on some versions of
201 :     Linux. The problem appears to be limited to large file systems that
202 :     have more than 2^32^ inodes.
203 :     +
204 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
205 :    
206 :     //--------------------------------------------------------------------
207 :     [2014/09/13]::
208 :     +
209 :     Added +%value+ directive to *ml-antlr*; this addition improves the
210 :     error repair choices by allowing non-nullary tokens to be inserted
211 :     when making repairs.

218 :    
219 :     //--------------------------------------------------------------------
220 : jhr 4002 [2014/08/21]::
221 :     +
222 :     Created new +doc+ tree in *SML/NJ* repository. Currently this
223 :     tree just holds the sources for UNIX-style manual pages for
224 :     the command-line tools (fixing bug bugref:[35]). The documentation
225 :     is written using the http://asciidoc.org[ASCIIDOC] format. Use
226 :     the following *svn* command to checkout a copy of the documentation tree:
227 :     +
228 :     [source,sh]
229 :     -----------
230 :     svn co https://smlnj-gforge.cs.uchicago.edu/svn/smlnj/doc/trunk doc

234 :    
235 :     //--------------------------------------------------------------------
236 : jhr 3992 [2014/08/19]::
237 :     +
238 :     Compiling the runtime system on *cygwin* was failing because the file
239 :     +exceptions.h+ was missing. It appears to have been part of previous
240 :     versions, so a version has been incorporated verbatim in the
241 :     file +runtime/mach-base/cygwin-fault.c+ file (fixes bug bugref:[125]).
242 :     +
243 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
244 :    
245 :     //--------------------------------------------------------------------
246 :     [2014/08/19]::
247 :     +
248 : jhr 4002 Added the +actionToString'+ and +repairToString'+ functions
249 :     to the +AntlrRepair+ structure. These functions allow one to
250 : jhr 3992 specialize the printing of tokens based on whether they are
251 :     being added or deleted.
252 :     +
253 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
254 :    
255 :     //--------------------------------------------------------------------
256 :     [2014/08/17]::
257 :     +
258 :     Added patches to support +OpenBSD+ on +PowerPC+. The patches were
259 :     contributed by Jasper Lievisse Adriaanse (fixes bug bugref:[124]).
260 :     +
261 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
262 :    
263 :     //--------------------------------------------------------------------
264 :     [2014/08/17]::
265 :     +
266 :     Use +mkstemp+ to implement +OS.FileSys.tmpName()+ on systems that support
267 :     it (should be all modern versions of *Unix*). This change fixes bug bugref:[128].
268 :     (Thanks to Johannes 5 Joemann).

270 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
271 :    
272 :     //--------------------------------------------------------------------
273 :     [2014/08/17]::
274 :     +
275 :     Fixed a bug in +IntInf.~>>+, which did not handle negative arguments
276 :     correctly (bug bugref:[110]).
277 :     +
278 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
279 :    
280 :     //--------------------------------------------------------------------
281 :     [2014/08/14]::
282 :     +
283 :     Fixed a problem in the CPS contraction phase. An optimization that
284 :     eliminates construction of a record that already exists was not
285 :     checking that the existing record was the same record kind (bug bugref:[119]).

288 :    
289 :     //--------------------------------------------------------------------
290 :     [2014/07/28]::
291 :     +
292 :     Switch to using +MAP_ANONYMOUS+ to allocate memory on Linux systems.
293 :     This change avoids problems when +"/dev"+ does not support execute
294 :     permission (as seems to be the case with some versions of *Linux*
295 :     running on ChromeBooks; bug bugref:[120]).

299 :     //--------------------------------------------------------------------
300 :     [2014/06/28]::
301 :     +
302 :     Fix for bug bugref:[127] (Crash on *Windows* with +OS.Process.system+).

305 :    
306 :     //--------------------------------------------------------------------
307 :     [2014/06/07]::
308 :     +
309 :     Fixed a long-standing bug in +Socket.recvVec+, which prevented the result
310 :     from being used in a string pattern match (thanks to Vesa Norrman
311 :     for the fix).

314 :    
315 :     //--------------------------------------------------------------------
316 :     [2014/05/01]::
317 :     +
318 :     Fixed minor issue in an error message; type variable name should be
319 :     printed with leading +'+.

322 :    
323 :     //--------------------------------------------------------------------
324 :     [2013/11/25]::
325 :     +
326 :     Added ++PackWord++{++16++,++32++}{++Big++,++Little++} structures
327 :     to the +Unsafe+ module. This change makes the +UNSAFE+ signature
328 :     closer to the http://mlton.org[*MLton*] version, although we
329 :     still need to add the +PackReal+ structures.

348 :     +
349 :     Fix bug bugref:[111] (+Socket.acceptNB+ returns somewhat broken sockets).
350 :     The problem was that under Win32, sockets returned from +accept+ inherit
351 :     their parents' non-blocking status, whereas on *UNIX* they are always
352 :     blocking.

367 :     +
368 :     Fix bug bugref:[116] (+Socket.sameDesc+ raises +Match+ exception).
369 :     The problem is that on Windows the +iodesc+ datatype (defined in
370 :     +Basis/Implementation/Win32/pre-os.sml+) has both an +IODesc+ constructor
371 :     and a +SockDesc+ constructor. Updated the code in +Win32/os-io.sml+ to

1248 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
1249 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
1250 :     +
1251 :     (In addition, CMB_REBUILD_MODE is defined for +makeml -rebuild+,

1253 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
1254 :     while running +CMB.make+. The point is that the single symbol
1255 :     NO_PLUGINS is definde in all three cases.)

1261 :     +
1262 :     When bootstrapping new versions of the compiler, there can be
1263 :     situations where the plugin tools for *ml-yacc* and *ml-lex* (or *ml-ulex*)
1264 :     are not available or otherwise not operational. In this case one can
1265 :     manually define the NO_PLUGINS symbol prior to running +CMB.make()+. To

1337 :     The *ml-antlr* specification format has changed: declarations such as
1338 :     +%tokens+ and nonterminal definitions can occur *multiple* times in the

1340 :     extends the previous ones. This does not apply to +%start+ or +%name+,
1341 :     of course.

1349 :     directive as in *ml-yacc*.

1352 :     cells, so the +:==+ and +!!+ notation has been deprecated.

1354 :     The *ml-antlr* tool now does much more checking of specifications, and
1355 :     its error messages have been greatly improved. Error repair for
1356 :     generated parsers has been completely rewritten, and is now both
1357 :     much faster and more accurate.
1358 :     +
1359 :     *ml-ulex* is now more lenient with escape codes (non-SML-standard
1360 :     escape codes are now interpreted literally, so _e.g._, +\|+ denotes "+|+").
1361 :     Also, character classes may now include a "+-+" character at the beginning
1362 :     as is standard in most other regexp tools.

1373 :     Significant changes in FLINT and the front end, mostly having to do
1374 :     with a reorganized system for handling primops. Various bug fixes
1375 :     and improvements in printing signatures.

1380 :     [2007/05/02]::
1381 :     +
1382 :     Preliminary commit of large *ml-lpt* revisions (more to come for 110.64).
1383 :     The *ml-antlr* specification format has changed: declarations such as
1384 :     +%tokens+ and nonterminal definitions can occur *multiple* times in the
1385 :     same specification. The semantics are such that each new declaration
1386 :     extends the previous ones. Grammar extension constructs have also
1387 :     changed. We now allow type annotations on nonterminals. Finally,
1388 :     the refcell construct is now implemented using SML's regular reference
1389 :     cells, so the +:==+ and +!!+ notation has been deprecated. All of these
1390 :     changes will appear in the 110.64 user guide for *ml-lpt*.
1391 :     +
1392 :     The *ml-antlr* tool now does much more checking of specifications, and
1393 :     its error messages have been greatly improved. There has also been
1394 :     some work on the error repair process for generated parsers, but this
1395 :     will be further improved in 110.64.

1402 :     More Basis fixes: The +Char.fromString+ (_etc._) functions did not handle
1403 :     the "+\uxxxx+" escape sequence. There is still an outstanding bug with
1404 :     +String.fromString+ the tail is a format escape. I added a comment to

1554 :     the interface for creating streams in *ml-ulex* (we now support
1555 :     stream creation from several kinds of sources). Overall, the
1556 :     tools are now quite stable, and their interfaces are unlikely to

1569 :     and *ml-antlr*.
1570 :     +
1571 :     For *ml-yacc* and *ml-lex* we continue to have permanently "plugged-in"
1572 :     CM tools. (It turns out to be too messy to do otherwise because
1573 :     there is too much code that during installation relies on the presence
1574 :     of these tools -- resulting in a tricky ordering problem.)

1582 :     Modified CM's startup code to use +shiftArgs+ as it processes
1583 :     command line arguments. This way, the init code in each .sml-file
1584 :     or library that is mentioned at the top level will see only
1585 :     those arguments that have not yet been processed at this point.
1586 :     In other words, the init code can "seize control" and process the

1743 :     +
1744 :     directory containing two new program generator tools: *ml-ulex* and

1746 :     LL(k) parser generator). These tools are currently "beta-quality"
1747 :     +
1748 :     The latest versios of the sources can now be obtained anonymously

1752 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin

1778 :     +
1779 :     This is a temporary solution, more reorganization is to come.
1780 :     +
1781 :     The basic idea is to have a number of toplevel trees, each corresponding
1782 :     to a well-defined part of the overall system. Each part can be
1783 :     maintained individually, even in separate source repositories,
1784 :     although currently we still serve everything out of the main
1785 :     smlnj-gforge tree.
1786 :     +
1787 :     Installer and and scripts have been updated to reflect the new
1788 :     layout. The installer (base/src/system/smlnj/installer) is now
1789 :     "scriptable" to avoid burning too much knowledge about the
1790 :     layout into SML source code. The main script used by the installer

2067 :     +
2068 : jhr 4002 Reversed change to +src/system/smlnj/internals/versiontool.cm+. This
2069 : jhr 3992 file gets loaded as a tool -- by the equivalent of CM.make during the
2070 : jhr 4002 run of +CMB.make+. Thus, CMB's path configuration is meaningless for
2071 : jhr 3992 it. Instead, it has the status of "user code", so it should use
2072 : jhr 4002 +$/basis.cm+ to refer to the Basis library. (At least that's true for
2073 : jhr 3992 the purpose of bootstrapping the previous change. In the future it
2074 : jhr 4002 might make sense to have +versiontool.cm+ refer to
2075 :     +$smlnj/basis/basis.cm+, _i.e._, the version of the Basis that the
2076 : jhr 3992 compiler itself uses.)
2077 :     +

2093 :     $/controls-lib.cm
2094 :     $/html-lib.cm
2095 :     $/ml-yacc-lib.cm
2096 : jhr 4002 ....................
2097 : jhr 3992 +
2098 :     These libraries are now internally (as seen from the source code
2099 :     of the implementation itself) known by the following names:
2100 :     +
2101 : jhr 4002 ....................
2102 : jhr 3992 $smlnj/basis/basis.cm

2108 : jhr 4002 ....................
2109 : jhr 3992 +
2110 :     This makes it possible to work with code that requires different
2111 :     versions of these libraries, and which refers to these libraries using
2112 :     their "default" names (_i.e._, the first set of names above). In other
2113 :     words, one can un-define or re-define those default names without
2114 :     compromising the proper functioning of the compiler itself.
2115 :     +
2116 :     A similar procedure had already been performed for several of the
2117 : jhr 4002 *MLRISC* libraries that are linked into the compiler. I did some
2118 : jhr 3992 cleanup on this code.
2119 :     +
2120 :     A new file in the config directory (named extrapathconfig) is
2121 :     responsible for setting up path anchors that the compiler itself does
2122 :     not need, but that are typically required by user code.

2272 :     //--------------------------------------------------------------------
2273 :     [2005/05/18]::
2274 :     +
2275 : jhr 4002 Added support scripts for *Mac OS X PackageMaker* and modified

2288 :     //--------------------------------------------------------------------
2289 :     [2005/05/16]::
2290 :     +
2291 :     Added mechanism for re-creating a heap file for the interactive system
2292 :     after configuration variables have been changed.
2293 :     +
2294 : jhr 4002 [source,sml]
2295 :     ------------
2296 : jhr 3992 CM.redump_heap : string -> unit
2297 : jhr 4002 ------------
2298 : jhr 3992 +
2299 : jhr 4002 This is much like +SMLofNJ.exportML+, but starting from the resulting
2300 :     heap does not return to the caller of +CM.redump_heap+ but
2301 : jhr 3992 restarts the interactive system from scratch. The original call of
2302 : jhr 4002 +CM.redump_heap+ does not return but ends the interactive session.
2303 :     Thus, +CM.redump_heap+ is a lot like +SMLofNJ.exportFn+.
2304 : jhr 3992 +
2305 : jhr 4002 Internally, +redump_heap+ winds the dynamic execution context back to
2306 : jhr 3992 the point where the original heap image was created and re-executes
2307 :     the heap image generation code in the boot code.

2314 : jhr 4002 Added a hack to the existing hack known as +Word64+ to make +fromString+

2316 : jhr 3992 as specified with respect to the interaction of radix and prefix.

2383 :     [2005/02/10]::

2408 :     //--------------------------------------------------------------------
2409 :     [2005/01/14]::
2410 :     +
2411 : jhr 4002 Implemented new (but still experimental) *heap2exec* facility. This is
2412 : jhr 3992 tested under Mac OS X and should work under Linux (will test shortly).
2413 :     It will probably also work on the Sparc (will test some time later).
2414 : jhr 4002 Also removed old "+HACKED_STANDALONE+" hack from runtime
2415 : jhr 3992 +
2416 : jhr 4002 To be able to test *heap2exec*, uncomment the request for "+heap2asm+" in
2417 : jhr 3992 config/targets prior to installation. (Notice that this is different
2418 :     from "heap2exec" mentioned below. Not a typo.)
2419 :     +
2420 :     To perform an actual test, run the command
2421 :     +
2422 :     $ bin/heap2exec heapfile execfile
2423 :     +
2424 : jhr 4002 (You can put *heap2exec* on your shell's path.)
2425 : jhr 3992 +
2426 :     For example, run
2427 :     +
2428 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2429 :     +
2430 : jhr 4002 This will create a standalone executable called "+mly+" that you can

2454 :     data structure access seems to work.)
2455 :     +
2456 : jhr 4002 * Fixed *CM*'s incorrect assumption that the PPC is little-endian.
2457 : jhr 3992 (On the Mac, it is big-endian. And that's currently our only

2623 : jhr 3995 - Stripped down the +versiontool:+ It now only handles the version number.
2624 : jhr 3992 The date string is generated at bootstrap time (during makeml).
2625 :     +
2626 :     - In a previous commit, fixed a minor issue with how polyequal is being
2627 :     translated. In particular, the code now "looks through" abstractions.
2628 :     This results in slightly fewer polyEqual warnings and hopefully slightly
2629 :     more efficient code. Important examples for where this matters are
2630 : jhr 3995 the new +int64+ and +word64+ types.

2645 : jhr 3995 All the pieces of +Word64+ are now there, with the exception of the
2646 :     conversions from and to +LargeWord+. (Eventually these need to be identities,
2647 :     but for the time being they don't even make sense because +LargeWord+ is
2648 : jhr 3992 32-bit wide.)

2657 :     +
2658 : jhr 3995 Structure +Word64+ is now (almost) complete, word literals and patterns
2659 : jhr 3992 seem to work. There are a few odd pieces missing. In particular,
2660 : jhr 3995 I didn't do the {++from++,++to++}++LargeWord++ parts because +LargeWord+
2661 :     is still +Word32+ at the moment.
2662 : jhr 3992 +
2663 : jhr 3995 Making +Word64+ official would mean that +LargeWord+ becomes +Word64+. But
2664 : jhr 3992 this requires extreme care because most word-word conversions have to
2665 : jhr 3995 go through +LargeWord+, so making a mistake means loss of efficiency or
2666 : jhr 3992 worse. Eventually there will be a solution similar to (but actually
2667 : jhr 3995 simpler than) what I did with +IntInf+.

2741 :     Added a mechanism for getting back-trace information from standalone
2742 :     programs. Here is how it works:
2743 :     +
2744 : jhr 4002 --
2745 :     . The part of the program from which you want to get backtrace
2746 :     information (usually the whole program) should be wrapped with
2747 :     BackTrace.monitor. This is a +(unit->'a)->'a+ function, and your

2760 :     ------------
2761 : jhr 3992 +

2764 :     main function.
2765 : jhr 3992 +
2766 : jhr 4002 . Remove all compiled code (_i.e._, all the .cm/ subdirectories that

3025 :     by a file name suffix of "+.lml+".
3026 : jhr 3992 +
3027 : jhr 3995 In addition to the above feature, the original class "+sml+" now also
3028 :     supports a tool argument "+lazy+" which has the same effect. As a
3029 : jhr 3992 result, the following three lines are equivalent:
3030 :     +
3031 : jhr 3995 ....................
3032 : jhr 3992 foo.sml : lazysml
3033 :     foo.sml : sml (lazy)
3034 :     foo.sml (lazy)
3035 : jhr 3995 ....................
3036 : jhr 3992 +
3037 :     The setting goes into effect both during parsing and during
3038 :     compilation. The original setting is restored right after parsing and
3039 :     after compilation, respectively.
3040 :     +
3041 :     In addition to all the above, there is also a general mechanism to set
3042 :     ANY of the "controls" that are available at the command line via
3043 : jhr 3995 "+-C...+" on a per-sml-file basis. The same rules that apply for "+lazy+"
3044 :     apply as well. (In fact, "+lazy+" is implemented as a special case of
3045 : jhr 3992 the general mechanism.)
3046 :     +
3047 : jhr 3995 The +.cm+ file syntax uses a new keyword tool argument called "+with+".
3048 : jhr 3992 There are several ways of indicating the desired settings:
3049 :     +
3050 : jhr 3995 ....................
3051 : jhr 3992 foo.sml (with:parser.quotations=true)
3052 :     foo.sml (with:(name:parser.quotations value:true))
3053 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
3054 :     foo.sml (with:(name1=value1 name2=value2 ...))
3055 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
3056 : jhr 3995 ....................
3057 : jhr 3992 +
3058 : jhr 3995 Another possible abbreviation is to leave out the +=v+ or +value:v+ part
3059 : jhr 3992 if the name refers to a boolean control (in which case the value is
3060 :     taken to be true). Thus, one could get lazy sml also by saying:
3061 :     +
3062 : jhr 3995 ....................
3063 : jhr 3992 foo.sml (with:parser.lazy-keyword=true)
3064 :     foo.sml (with:parser.lazy-keyword)
3065 :     foo.sml (with:(name:parser.lazy-keyword value:true))
3066 :     foo.sml (with:(name:parser.lazy-keyword))

3408 :     In the case of Unix there still seems to be an open/weird issue:
3409 :     +
3410 :     The {text,bin}{In,Out}streamOf functions are supposed to create
3411 :     fresh streams whenever they are called -- as opposed to have them
3412 :     return the same stream every time. This design is supposed to
3413 :     prevent space leaks caused by proc values hanging on to streams.
3414 :     +
3415 :     The reap function, on the other hand, is supposed to close the
3416 :     streams. This cannot be done without having a handle on the
3417 :     stream in proc after all...
3418 :     +
3419 :     I took the liberty to implement the following stopgap solution:
3420 :     +
3421 :     The proc value hangs on to the most recently created stream(s).
3422 :     Reap closes those. If either or both of the two streams hadn't
3423 :     been created at all yet, then reap will close the corresponding
3424 :     file descriptors directly.

3442 :     CM now ignores (but still accepts) the "owner" information in group
3443 :     descriptions. The owner of a group is its next enclosing
3444 :     library. Each group must have a unique owner. (There is a virtual
3445 :     "toplevel" library that owns groups which are not nested within a real
3446 :     library.) Previously, each group had to explicitly declare its owner,
3447 :     and CM would check that such a declaration is correct. The new scheme
3448 :     is to have CM check that for each group there is precisely one owning
3449 :     library.
3450 :     +
3451 :     The advantage of the new scheme is that the programmer no longer needs
3452 :     to maintain the somewhat annoying owner information. The downside is
3453 :     that CM cannot enforce the ownership rule across multiple runs of
3454 :     CM.make. Fortunately, enclosing the same group in two different
3455 :     libraries A and B which are not part of the same program does not
3456 :     cause real problems.

3499 :     for the voluminous patch!
3500 :     +
3501 :     (I have not tested this patch under win32 yet.)
3502 :     +
3503 :     Here is David's e-mail:
3504 :     +
3505 :     Hi,
3506 :     +
3507 :     Attached to this email you find a diff against sml/nj 110.45
3508 :     that will enable socket support under Windows.
3509 :     +
3510 :     To apply the patch (using unix or cygwin)
3511 :     1) gunzip runtime.diff.gz
3512 :     2) "cd" into "src/runtime" in the source tree of a fresh
3513 :     110.45 installation.
3514 :     3) patch -p 1 < [your/path/to]runtime.diff
3515 :     +
3516 :     The code compiles fine but has NOT yet been extensively tested.
3517 :     I only ran a few tests for basic socket client functionality
3518 :     (which worked fine). Especially the functions that use ioctl
3519 :     are not tested at all and might not work (see below).
3520 :     +
3521 :     I implemented this since we want to move to a newer version of sml/nj
3522 :     but need socket support in order to use it. This is the first time I
3523 :     even had a look at the sml/nj source, so please review my changes
3524 :     before making this part of the distribution! Here are a few issues
3525 :     that I think might be better for someone to solve who is more
3526 :     familiar with the sml/nj source (and socket programming):
3527 :     +
3528 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3529 :     exception since I could not figure out what the windows equivalent
3530 :     of these functions is
3531 :     +
3532 :     - In sockets-osdep.h there are a some #include statements that are
3533 :     only used in a few files that include sockets-osdep.h
3534 :     +
3535 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3536 :     does not process its return value since I don't know how to
3537 :     report an error upwards.
3538 :     +
3539 :     - It would probably be good to have a call to WSACleanup() when
3540 :     the library is unloaded (if there is such a possibility).
3541 :     Otherwise I think Windows will take care of this automatically
3542 :     when the process finishes.
3543 :     +
3544 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3545 :     no idea if that is actually the proper replacement on Windows.
3546 :     +
3547 :     - All these issues are marked in the code by "FIXME" comments.
3548 :     +
3549 :     We use sml/nj extensively in our products and are quite happy
3550 :     with it. I hope this contribution will help you.
3551 :     +
3552 :     Keep up the good work!

3801 :     +
3802 :     1. Fixed SOCKET API and implementation to match Basis spec.
3803 :     This required changing the internal representation of sockets to one
3804 :     that remembers (for each socket file descriptor) whether it is currently

3810 :     between Unix and Win32.

3812 :     3. CML's socket API changed accordingly.
3813 :     (Note that we need to remove non-blocking functions from this API

3861 :     [2003/09/18]::
3862 :     +
3863 :     1. Exported fractionsPerSecond etc. from TimeImp (but not from Time as
3864 :     this seems to be controversial at the moment) and used those in

3866 :     +
3867 :     2. Added Time.{from,to}Nanoseconds to Time.

3921 :    
3922 :    
3923 :     //--------------------------------------------------------------------
3924 :     [2003/09/09]::
3925 :     +
3926 :     Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
3927 :     Modified config/install.bat to take advantage of it. Also modified
3928 :     config/install.sh (and called it config/new-install.sh) to take advantage
3929 :     of it on Unix systems. (The SML code is (supposed to be) platform-
3930 :     independent.)
3931 :     +
3932 :     The installer can now install everything under Win32
3933 :     as well as under *nix as long as it compiles.
3934 :     +
3935 :     Other changes:
3936 :     +
3937 :     - made CML compile again under Win32
3938 :     - made eXene compile under Win32 (by providing a fake structure UnixSock
3939 :     and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
3940 :     - fixed a bug in nowhere: it assumed that type OS.Process.status is the
3941 :     same as type int; under Win32 it isn't
3942 :     - fixed some slice-related problems in the win32-specific parts of CML
3943 :     - added a functor argument "sameVol" to os-path-fn.sml in the Basis
3944 :     (under Win32, the volume name is case-insensitive, and the
3945 :     OS.Path code compares volume names for equality)

3951 :     +
3952 :     Made Win32 version of OS.FileSys.fullPath return current directory
3953 :     when given an empty string. This is what the spec says, and incidentally,
3954 :     CM depends on it. (CM otherwise goes into an infinite loop in certain
3955 :     cases when presented with the name of a non-existing .cm file.)

3958 : jhr 3992
3959 :     //--------------------------------------------------------------------
3960 :     [2003/09/04]::
3961 :     +
3962 :     1. Changed interface to vectors and arrays in Basis to match
3963 :     (draft) Basis spec.
3964 :     2. Added signatures and implementations of slices according to
3965 :     Basis spec.
3966 :     3. Edited source code throughout the system to make it compile again
3967 :     under 1. and 2. (In some cases code had to be added to have it
3968 :     match the new signatures.)
3969 :     4. MLRISC should be backward-compatible: the copies of the originals
3970 :     of files that needed to change under 3. were retained, the .cm files
3971 :     check the compiler version number and use old versions when
3972 :     appropriate.
3973 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
3974 :     dirstream -> string option (in accordance with Basis spec).
3975 :     6. When generating code that counts lines, *ml-lex* used function
3976 :     CharVector.foldli, taking advantage of its old interface.
3977 :     This has been replaced with the corresponding code from
3978 :     CharVectorSlice. (html-lex must be re-lexed!)
3979 :     7. BitArray in smlnj-lib/Util has been extended/modified to match the
3980 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
3981 :     8. Removed temporary additions (fromInternal, toInternal) from the
3982 :     (now obsolete) IntInf in smlnj-lib/Util.
3983 :     9. Cleaned up structure Byte.
3984 :     10. Added localOffset, scan, and fromString to Date (according to spec).
3985 :     Cleaned/corrected implementation of Date.
3986 :     (Still need to check for correctness; implement better canonicalizeDate.)
3987 :     11. Added "scan" to signature IEEE_REAL.
3988 :     12. Some improvements to IntInf [in particular: efficiency-hack for
3989 :     mod and rem when second operand is 2 (for parity checks).]
3990 :     13. Changed representation of type Time.time, using a single IntInf.int
3991 :     value counting microseconds. This considerably simplified the
3992 :     implementation of structure Time. We now support negative time
3993 :     values; scan and fromString handle signs.
3994 :     14. Functor PrimIO now takes two additional arguments (VectorSlice and
3995 :     ArraySlice).

3999 :     //--------------------------------------------------------------------
4000 :     [2003/08/28]::
4001 :     +
4002 :     This is a major update which comes with a version number bump
4003 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
4004 :     and an implementation of IntInf in the Basis.
4005 :     +
4006 :     There are a fairly large number of related changes and updates throughout
4007 :     the system:
4008 :     +
4009 :     Basis:
4010 :     - Implemented IntInf.
4011 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
4012 :     - Added some missing Real64 operations, most notably Real.toLargeInt.
4013 :     - Added FixedInt as a synonym for Int32.
4014 :     +
4015 :     compiler:
4016 :     * Added support for a built-in intinf type.
4017 :     - literals
4018 :     - pattern matching
4019 :     - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
4020 :     - overloading on literals and operations
4021 :     +
4022 :     This required adding a primitive type intinf, some additional
4023 :     primops, and implementations for several non-trivial intinf
4024 :     operations in Core. (The intinf type is completely abstract
4025 :     to the compiler; all operations get delegated back to the Core.)
4026 :     +
4027 :     * Intinf equality is handled by polyequal. However, the compiler
4028 :     does not print its usual warning in this case (since polyequal
4029 :     is the right thing to do there).
4030 :     +
4031 :     * Improved the organization of structure InlineT.
4032 :     +
4033 :     * A word about conversion primops:
4034 :     If conversions involving intinf do not cancel out during
4035 :     CPS contract, then the compiler must insert calls to Core functions.
4036 :     Since all core access must be resolved already during the FLINT
4037 :     translate phase, it would be too late a the time of CPS contract
4038 :     to add new Core calls. For this reason, conversion primops
4039 :     for intinf carry two arguments: 1. the numeric argument that
4040 :     they are supposed to convert, and 2. the Core function that
4041 :     can help with this conversion if necessary. If CPS contract
4042 :     eliminates a primop, then the associated Core function becomes
4043 :     dead and goes away. Intinf conversion primops that do not get
4044 :     eliminated by CPS contract get rewritten into calls of their
4045 :     core functions by a separate, new phase.
4046 :     +
4047 :     interactive system:
4048 :     - Control.Print.intinfDepth controls max length of intinf constants
4049 :     being printed. (Analogous to Control.Print.stringDepth.)
4050 :     - Cleanup in printutil and pputil: got rid of unused stuff and
4051 :     duplicates; replaced some of the code with code that makes better
4052 :     use of library functionality.
4053 :     +
4054 :     CM:
4055 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
4056 :     are no longer silent.
4057 :     +
4058 :     CKIT:
4059 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
4060 :     in favor of LargeInt -- which is now the same as IntInf.
4061 :     CKIT-knowledgable people should check whether this is what's
4062 :     intended and otherwise change things back to using Int32 or
4063 :     FixedInt.
4064 :     +
4065 :     Throughout the code:
4066 :     Started using IntInf.int literals and built-in operations
4067 :     (_e.g._, comparison with 0) where this seems appropriate.

4072 :     //--------------------------------------------------------------------
4073 :     [2003/08/13]::
4074 :     +
4075 :     Merging changes from the mcz-branch development branch into trunk.
4076 :     These changes involve replacement of the emulated old prettyprinter
4077 :     interface with direct use of the SML/NJ Lib PP library, and fixing
4078 :     of a couple of bugs (895, 1186) relating to error messages. A new
4079 :     prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
4080 :     has been added.

4086 :    
4087 :    
4088 :     //--------------------------------------------------------------------
4089 :     [2003/08/11]::
4090 :     +
4091 :     This patch restores SML/NJ's ability to run under win32. There are a
4092 :     number of changes, including fixes for several bugs that had gone
4093 :     unnoticed until now:
4094 :     +
4095 :     - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
4096 :     trying to run the win32 version from within cygwin.)
4097 :     +
4098 :     - There are a number of simple .bat scripts that substitute for their
4099 :     corresponding Unix shell-scripts. (See below.)
4100 :     +
4101 :     - The internals of *ml-build* have been modified slightly. The main
4102 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
4103 :     using OS.Process.system, the ML process delegates this task back
4104 :     to the script. Otherwise problems arise in mixed environments such
4105 :     as Cygwin where scripts look and work like Unix scripts, but
4106 :     where OS.Process.system cannot run them.
4107 :     +
4108 :     - In CM, the srcpath pickler used native pathname syntax -- which
4109 :     is incorrect in the case of cross-compilation. The new pickle format
4110 :     is independent of platform-specific naming conventions.
4111 :     +
4112 :     - Path configuration files (such as lib/pathconfig) can now choose
4113 :     between native and standard syntax. Placing a line of the form
4114 :     +
4115 :     standard!
4116 :     +
4117 :     into the file causes all subsequent paths to be interpreted using
4118 :     CM standard pathname syntax (= Unix conventions); a line
4119 :     +
4120 :     native!
4121 :     +
4122 :     switches back to native style. This was needed so that
4123 :     path config files can be written portably, see src/system/pathconfig.
4124 :     +
4125 :     - Runtime system:
4126 :     +
4127 :     - win32-filesys.c: get_file_time and set_file_time now
4128 :     access modification time, not creation time.
4129 :     +
4130 :     - I/O code made aware of new array representation.
4131 :     +
4132 :     - Bug fixes in X86.prim.masm.
4133 :     +
4134 :     - src/system/makeml made aware of win32. (For use under cygwin
4135 :     and other Unix-environments for windows.)
4136 :     +
4137 :     - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
4138 :     which caused BinIO.inputAll to fail consistently.
4139 :     +
4140 :     .bat scripts:
4141 :     +
4142 :     Windows .bat scripts assume that +SMLNJ_HOME+ is defined.
4143 :     +
4144 :     - sml.bat, ml-yacc.bat, ml-lex.bat: Driver scripts for standalone
4145 :     applications (sml, *ml-yacc*, *ml-lex*).
4146 :     - ml-build.bat: analogous to *ml-build*.
4147 :     - config\install.bat: Analogous to config/install.sh. This requires
4148 :     that +SMLNJ_HOME+ is set and that Microsoft Visual C is ready to use.
4149 :     (nmake etc. must be on the path, and vcvars32 must have been run.)
4150 :     Moreover, sources for *ml-lex* and *ml-yacc* need to exist under src,
4151 :     and the bootfile hierarchy must have been unpacked under
4152 :     sml.boot.x86-win32.
4153 :     The script is very primitive and does a poor job at error checking.
4154 :     It only installs the base system, *ml-lex*, and *ml-yacc*. No other
4155 :     libraries are being installed (_i.e._, you get only those that
4156 :     are part of the compiler.)
4157 :     - link-sml.bat: analogous to .link-sml, but not currently used
4158 :     +
4159 :     Unrelated bug fixes:
4160 :     +
4161 :     - ml-nlffigen now exports structures ST_* corresponding to incomplete
4162 :     types.
4163 :     - Added getDevice to PP/src/pp-debug-fn.sml. (Would not compile
4164 :     otherwise.)

4168 :     //--------------------------------------------------------------------
4169 :     [2003/06/17]::
4170 :     +
4171 :     Modified compiler/Elaborator/print/pptype.sml to fix bug 895.
4172 :     Tag will be used for new development branch (mcz-branch) for
4173 :     use by MacQueen, (Lucasz) Zairek, and (George) Cao at uchicago.

4184 :     //--------------------------------------------------------------------
4185 :     [2003/05/21]::
4186 :     +
4187 :     Two changes:
4188 :     +
4189 :     1. Added a flag for controlling whether non-exhaustive bindings will
4190 :     be treated as errors (default is false).
4191 :     2. Cleaned up the *entire* source tree so that CMB.make goes through
4192 :     without a single non-exhaustive match- or bind warning.

4195 : jhr 3992
4196 :     //--------------------------------------------------------------------
4197 :     [2003/05/17]::
4198 :     +
4199 :     1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
4200 :     +
4201 :     This mainly affects the quality of error messages. However, some
4202 :     of the code is now more straightforward than before. (Treatment of
4203 :     the above four constructs in translate.sml is much simpler than
4204 :     the "macro-expansion" that was going on before. Plus, the mach-
4205 :     compiler no longer gets invoked just to be able to compile an
4206 :     if-expression.)
4207 :     +
4208 :     2. The ErrorMsg.Error exception is now caught and absorbed by the
4209 :     interactive loop.

4213 :     //--------------------------------------------------------------------
4214 :     [2003/05/16]::
4215 :     +
4216 :     Ported the runtime system to cygwin, which uses the unix
4217 :     x86-unix bin files. Missing/buggy features:
4218 :     +
4219 :     o getnetbyname, getnetbyaddr: these functions seem to be missing in
4220 :     the Cygwin library.
4221 :     o Ctrl-C handling may be flaky.
4222 :     o Windows system calls and Windows I/O are not supported.
4223 :     +
4224 :     A new set of binfiles is located at:

4226 :     http://www.dorsai.org/~leunga/boot.x86-unix.tgz
4227 :     +

4251 :     [2002/12/12]::
4252 :     +
4253 :     Fixed a serious bug in the rewrite code for FP spilling/reloading that
4254 :     sent the RA into an infinite loop when floating point registers get
4255 :     spilled. (Because of this bug, _e.g._, nucleic stopped compiling between
4256 :     110.37 and 110.38.)
4257 :     There was another set of potential problems related to the handling of

4265 :     Added a call of SrcPath.sync at the beginning of Parse.parse (in CM).
4266 :     This fixes the problem of CM getting confused by files that suddenly
4267 :     change their identity (_e.g._, by getting unlinked and recreated by some
4268 :     text editor such as vi). There might be a better/cheaper/cleaner way
4269 :     of doing this, but for now this will have to do.

4287 :     In good old tradition, there has been a slight hiccup so that we have
4288 :     to patch 110.42 after the fact. The old release tag has been replaced
4289 :     (see below).
4290 :     +
4291 :     The change solves a problem with two competing approaches the
4292 :     configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
4293 :     each other's way.
4294 :     +
4295 :     This change only affects the runtime system code and the installer script.
4296 :     (No new bootfiles.)

4307 :     The mltree operator DIVS must be implemented with an overflow check on
4308 :     the PPC because the hardware indicates divide-by-zero using "overflow" as
4309 :     well.

4316 :     Sml now senses the +SMLNJ_HOME+ environment variable. If this is set,
4317 :     then the bin dir is assumed to be in +$SMLNJ_HOME/bin+ and (unless
4318 :     +CM_PATHCONFIG+ is also set), the path configuration file is assumed
4319 :     to be in +$SMLNJ_HOME/lib/pathconfig+. This way one can easily move
4320 :     the entire tree to some other place and everything will "just work".
4321 :     +
4322 :     (Companion commands such as *ml-build* and *ml-makedepend* also sense this
4323 :     variable.)
