1 : monnier 2 This is a record of changes made to CML and the CML Library.
2 :     ------------------------------------------------------------
3 : jhr 1267
4 : jhr 3573 [2011-02-18]
5 :     Added barriers. These are inspired by the similar mechanism in CHP, although
6 :     we do not include any event-based operations on them as of yet.
7 :    
8 : jhr 3107 [2008-07-16]
9 :     Fixed interface to OS.Process so that it agrees with the SML Basis Library
10 :     (added isSuccess and sleep; status is nolonger an eqtype).
11 :    
12 : blume 2748 [2007-09-06]
13 :     Exported Int64 and IntInf from basis.cm.
14 :    
15 : blume 2338 [2007-02-15]
16 :     Updates to the cml-lib to track removals from the SML/NJ library.
17 :    
18 : jhr 2271 [2007-01-28]
19 :     Updates to the cml-lib to track additions to the SML/NJ library.
20 :    
21 : blume 2229 [2006-12-07]
22 :     Carried over the fix to the SOCKET signature.
23 :    
24 : jhr 1927 [2006-05-04]
25 :     Fixed bug with iGetPoll, mTakePoll, and mGetPoll. In some cases, the
26 :     atomic region was not being closed properly. The iGetPoll and mGetPoll
27 :     operations just read the value field now, since there is reads are
28 :     atomic.
29 :    
30 : jhr 1901 [2006-02-27]
31 :     Fixed bug with the combination of withNack and never, where the
32 :     negative acknowledgement is never generated. Thanks to Heath
33 :     Putnam for the bug report and fix.
34 :    
35 : mblume 1770 [2005-02-28]
36 :     Fixed serious bug in structure Atom. (Must use mvar, not mailbox!)
37 :    
38 : mblume 1759 [2005-02-24]
39 :     Reuse signature ATOM from $/smlnj-lib.cm, thus tracking all changes.
40 :     Implement structure Atom in terms of structure Atom in $/smlnj-lib.cm
41 :     by protecting access to the global hashtable using an mbox lock.
42 :     Atoms can now be created (sequentially) prior to calling RunCML.doit.
43 :    
44 : mblume 1717 [2004-11-24]
45 :     Made the IO implementation agnostic of size of Position.int.
46 :     (Now compiles with either Position = Int31 or Position = Int64.)
47 :    
48 : mblume 1389 [2003-09-23]
49 :     Accounted for changes to socket API in Basis. (Non-blocking
50 :     behavior is no longer a stateful property of a socket. Instead,
51 :     there are non-blocking versions of most functions in the
52 :     interface. This simplifies the CML code since it no longer
53 :     has to do OS-specific handling of "wouldblock" etc.
54 :     On the other hand, (trivial) CML implementations of those
55 :     non-blocking operations had to be added.)
56 :    
57 : mblume 1368 [2003-09-12]
58 :     Accounted for changed type of inputLine.
59 :    
60 : mblume 1354 [2003-09-09]
61 :     Made CML compile under Win32 again.
62 :    
63 : mblume 1350 [2003-09-03]
64 :     Added *_SLICE signatures and *Slice structures (copied from
65 :     "normal" Basis into CML Basis).
66 :     Fixed code broken due to API changes (slices).
67 :    
68 : jhr 1323 [2003-05-09]
69 :     Added the missing implementation of StreamIO event constructors
70 :     (e.g., TextIO.StreamIO.inputEvt). Note that if you use these
71 :     operations, then the system may not shutdown when all user threads
72 :     are blocked.
73 :    
74 : jhr 1322 [2003-04-21]
75 :     The CleanUp.logMailbox function was not protected against
76 :     interrupts (thanks to David Benson for catching this bug).
77 :    
78 : mblume 1320 [2003-04-09]
79 :     Changed the name of the directory cml-lib/cm to cml-lib/cm-descr
80 :     in order to avoid a name conflict with cml-lib/CM which gets
81 :     created by the compilation manager. (On case-insensitive
82 :     filesystems such as the one used by MacOS X the two names clash.)
83 :    
84 : jhr 1321 [2003-03-10]
85 :     Documentation cleanup.
86 :    
87 : jhr 1267 [2002-10-01]
88 :     Fixed a bad space leak in the stream I/O implementations. The
89 :     cleanup hooks were holding onto the initial buffer, which
90 :     meant that the entire buffer chain would remain live as long
91 :     as the stream was live.
92 :    
93 : blume 844 [2001-06-20]
94 :     Ported to SML/NJ 110.33 (in particular, the new CM).
95 :     Under the new CM, the CML library is known as $cml/cml.cm
96 :     and there is a CML-specific replacement for $/basis.cm
97 :     known as $cml/basis.cm. Two additional libraries
98 :     ($cml/cml-internal.cm and $cml/core-cml.cm) are used
99 :     internally but should not be referred to directly by client code.
100 :     A CML-specific replacement for $/smlnj-lib.cm is
101 :     known as $cml-lib/smlnj-lib.cm. The trace module is
102 :     $cml-lib/trace-cml.cm. (The aforementioned $cml/core-cml.cm
103 :     exists mainly to make it possible for $cml-lib/trace-cml.cm
104 :     to refer to it.)
105 : monnier 2
106 : blume 844 [2001-03-8]
107 :     Fixed a problem in the ordering of clean-up actions. IO streams
108 :     were being cleaned before servers, which meant that servers could
109 :     not use I/O in initialization or shutdown.
110 : monnier 167
111 : blume 844 [2001-01-14]
112 :     Fixed a bug in the timeout manager. Cleanup actions were being
113 :     executed twice, which breaks withNack.
114 : monnier 167
115 : blume 844 [2000-12-12]
116 :     Fixed a bug in the I/O manager (core-cml/io-manager.sml), where
117 :     if there were two threads blocked on the same descriptor (one
118 :     reading and one writing), the result might be matched to the
119 :     wrong thread.
120 :    
121 :     [2000-09-28]
122 :     Version 1.0.13 (SML/NJ Version 110.0.7)
123 :    
124 :     [2000-09-27]
125 :     Updated the CML Library to track additions to the SML/NJ Library.
126 :    
127 :     [1999-12-08]
128 :     Fixed a collection of bugs in event.sml related to the handling of
129 :     negative acknowledgements.
130 :    
131 :     [1999-12-01]
132 :     Modified RunCML.doit to install a dummy print hook. This prevents
133 :     the bug of SML/NJ's print function being called during CML execution
134 :     (the CML print function is installed by code in TextIO, but that
135 :     code isn't loaded by CML when the application does not specifically
136 :     mention TextIO).
137 :    
138 :     Version 1.0.12 (SML/NJ 110.0.6 and 110.8)
139 : monnier 139 -----------------------------------------
140 : monnier 106
141 : blume 844 [1999-09-29]
142 :     Updated the CML Library to track additions to the SML/NJ Library.
143 : monnier 139
144 : blume 844 [1999-07-05]
145 :     Added support for Win32 sockets (thanks to Riccardo Pucella).
146 : monnier 139
147 : blume 844 [1998-08-04]
148 :     Added preliminary Win32 implementation (thanks to Riccardo Pucella).
149 : monnier 106
150 : blume 844 [1998-06-01]
151 :     Fixed type of inputLineEvt in CML_TEXT_STREAM_IO (thanks to A. Appel).
152 : monnier 106
153 : blume 844 [1998-03-12]
154 :     Fixed bug in ChanIOFn (failure to spawn threads).
155 :    
156 :    
157 : monnier 8 Version 1.0.11 (SML/NJ 109.33 and 110)
158 :     --------------------------------------
159 :    
160 : blume 844 [1997-11-21]
161 :     Added TextIO.scanStream function.
162 : monnier 8
163 : blume 844 [1997-11-21]
164 :     Added import of PathUtil:PATH_UTIL to CML library.
165 : monnier 8
166 :    
167 :     Version 1.0.10 (SML/NJ 109.32)
168 :     ------------------------------
169 :    
170 : blume 844 [1997-09-18]
171 :     Fixed a scheduler bug that occured when the atomicState was SignalPending
172 :     and atomicSwitchTo was used to exit the atomic region.
173 : monnier 8
174 : blume 844 [1997-09-15]
175 :     Fixed a bug in the RunCML.doit code that prevented multiple runs (this bug
176 :     was exposed by the previous bug fix).
177 : monnier 8
178 : blume 844 [1997-09-15]
179 :     Fixed a serious bug with the internal condition variables (Event.atomicCVarSet
180 :     was not changing the state of the variable).
181 : monnier 8
182 : blume 844 [1997-09-15]
183 :     Introduced datatype rebinding to eliminate some structure opening.
184 : monnier 8
185 : blume 844 [1997-09-14]
186 :     Moved definition of tidToString to RepTypes, so that it can be used in
187 :     debugging the CML internals.
188 : monnier 8
189 : blume 844 [1997-09-12]
190 :     Server initialization/shutdown is now handled by a dedicated cleanup
191 :     routine. Eventually, each server should define its own cleanup routine,
192 :     and we'll get rid of logServer.
193 : monnier 8
194 : blume 844 [1997-09-12]
195 :     Fixed bugs in the initialization and shutdown protocols for the standard
196 :     text streams.
197 : monnier 8
198 :    
199 : monnier 2 Version 1.0.9 (SML/NJ 109.31)
200 :     -----------------------------
201 :    
202 : blume 844 [1997-09-02]
203 :     Added cleanup code for the I/O stacks (including the standard I/O streams).
204 : monnier 2
205 : blume 844 [1997-08-29]
206 :     Implemented a clean-up mechansim that is similar to that provided by
207 :     SML/NJ. The logging of global servers for initialization/shutdown
208 :     is now done using cleaners, which provide somewhat finer control.
209 :     Channel and mailbox logging is still supported, but the initialization
210 :     is done by a dedicated cleaner. This change is part of the overhaul
211 :     of RunCML.
212 : monnier 2
213 : blume 844 [1997-08-28]
214 :     Qualified the use of the "cont" type constructor, which is no longer
215 :     available at top level.
216 : monnier 2
217 : blume 844 [1997-08-28]
218 :     Replaced a few holdover uses of "abstraction" with opaque signature matching.
219 : monnier 2
220 : blume 844 [1997-08-15]
221 :     RunCML.doit now returns an OS.Process.status value. If a CML program
222 :     uses OS.Process.{exit,terminate} to shutdown, then the status argument
223 :     is returned as the result. If the system shuts down because of deadlock,
224 :     the OS.Process.failure is returned.
225 : monnier 2
226 : blume 844 [1997-08-15]
227 :     Many changes to ensure that exportFn images do not include the entire
228 :     top-level environment. These include: using SMLofNJ.isolate to create
229 :     top-level continuations, and reimplementing RunCML.exportFn to do better
230 :     housekeeping. To get this to work also required a number of changes
231 :     to the SML/NJ sources.
232 : monnier 2
233 : blume 844 [1997-08-15]
234 :     Fixed bug in scheduler, where a timer interrupt in an atomic region
235 :     was not getting marked by SignalPending.
236 : monnier 2
237 : blume 844 [1997-07-24]
238 :     The TextIO.output* functions did not implement line buffering; this
239 :     has now been added.
240 : monnier 2
241 :    
242 :     Version 1.0.8 (SML/NJ 109.30)
243 :     -----------------------------
244 :    
245 : blume 844 [1997-07-11]
246 :     Changed uses of System.Unsafe to Unsafe.
247 : monnier 2
248 : blume 844 [1997-07-11]
249 :     Eliminated redefinition of Scheduler structure to avoid loss of inlining,
250 :     since the compiler handles this properly now.
251 : monnier 2
252 : blume 844 [1997-07-11]
253 :     Added Atom.atom' (tracking SML/NJ library changes)
254 : monnier 2
255 : blume 844 [1997-06-30]
256 :     Removed Array2:ARRAY2 from library, as this is now gone from the
257 :     SML/NJ library.
258 : monnier 2
259 :    
260 :     Version 1.0.7 (SML/NJ 109.29)
261 :     -----------------------------
262 :    
263 : blume 844 [1997-06-11]
264 :     Changed OS.IO.{pollErr,isErr} to OS.IO.{pollPri,isPri} (this tracks fixes
265 :     in the SML/NJ implementation of the SML Basis Library.
266 : monnier 2
267 : blume 844 [1997-06-11]
268 :     Changes to src/Unix/posix-bin-prim-io.sml to track basis fixes.
269 : monnier 2
270 :    
271 :     Version 1.0.6 (SML/NJ 109.28)
272 :     -----------------------------
273 :    
274 : blume 844 [1997-05-21]
275 :     Added a temporary fix so that input operations do not cause the whole
276 :     CML system to block waiting for input. Eventually, there should be a
277 :     CML version of the complete Posix API, which is the right way to avoid
278 :     this problem.
279 : monnier 2
280 : blume 844 [1997-05-21]
281 :     Added RunCML.exportFn.
282 :     NOTE: there are some problems with the size of exported images that
283 :     need to be tracked down and fixed.
284 : monnier 2
285 :    
286 :     Version 1.0.5 (SML/NJ 109.26)
287 :     -----------------------------
288 :    
289 : blume 844 [1997-03-18]
290 :     Added SyncVar.{mSwap,mSwapEvt} operations, and changed the implementation
291 :     of multicast channels to use it.
292 : monnier 2
293 : blume 844 [1997-03-17]
294 :     Modified SyncVar.{mGet,mGetEvt} to resume other blocked threads (just
295 :     as iGet does).
296 : monnier 2
297 : blume 844 [1997-03-16]
298 :     Fixed a bug in SyncVar.{mTake,mTakeEvt}, where the cell was not getting
299 :     emptied in some execution paths.
300 : monnier 2
301 : blume 844 [1997-03-15]
302 :     Added an "error thread," which is enqueued when CML is not running.
303 :     This thread will get dispatched if someone tries to execute a CML
304 :     operation without using RunCML.doit (not including channel allocation,
305 :     etc.). I also added a top-level call to Scheduler.reset, which will
306 :     ensure that the current thread ID is initialized.
307 : monnier 2
308 : blume 844 [1997-03-13]
309 :     Fixed a serious bug in SyncVar.{iPut,mPut}, where the cell was not
310 :     getting filled in some cases.
311 : monnier 2
312 :    
313 :     Version 1.0.4 (SML/NJ 109.25.2)
314 :     -------------------------------
315 :    
316 : blume 844 [1997-02-28]
317 :     Added some additional modules to the CML Library: IOUtil:IO_UTIL and
318 :     KeywordsFn. These were recent additions to the SML/NJ Library. I also
319 :     reorganized the directory structure of the CML library to make it easier
320 :     to track changes in the SML/NJ Library.
321 : monnier 2
322 : blume 844 [1997-02-28]
323 :     Tracked changes in location of continuation operations changed in SML/NJ.
324 : monnier 2
325 :    
326 :     Version 1.0.3 (SML/NJ 109.25.1)
327 :     -------------------------------
328 :    
329 : blume 844 [1997-02-25]
330 :     Fixed bugs in the implementation of the pauseHook and schedulerHook in
331 :     RunCMLFn (missing atomicBegin).
332 : monnier 2
333 : blume 844 [1997-02-25]
334 :     Fixed bug in implementation of TraceCML when TraceToFile was set as the
335 :     destination.
336 : monnier 2
337 : blume 844 [1997-02-18]
338 :     Fixed bug in random access support in BinIOFn and TextIOFn (bug also in
339 :     SML/NJ implementation).
340 : monnier 2
341 : blume 844 [1997-02-17]
342 :     Added logging/unlogging for global mailboxes.
343 : monnier 2
344 : blume 844 [1997-02-17]
345 :     Fixed bug in the TraceCML.unwatchThread. Also changed the implementation
346 :     to avoid potential races between unwatching a thread and its termination.
347 : monnier 2
348 : blume 844 [1997-02-15]
349 :     Various changes to the Scheduler module to improve robustness. Added
350 :     an exception handler around the function in enqueueTmpThread. Replaced
351 :     enqueueCurThread with enqueueAndSwitchCurThread, which keeps the thread
352 :     ID bookkeeping in the same place. And fixed a bug(?) where atomicSwitchTo
353 :     was failing to set the current thread ID properly.
354 : monnier 2
355 : blume 844 [1997-02-04]
356 :     Added sendPoll operation on channels to CML structure.
357 : monnier 2
358 :    
359 :     Version 1.0.2 (SML/NJ 109.25)
360 :     -----------------------------
361 :    
362 : blume 844 [1997-01-30]
363 :     Added documentation for the Multicast and TraceCML library modules.
364 : monnier 2
365 : blume 844 [1997-01-30]
366 :     Made minor improvements to the implementation of TraceCML.
367 : monnier 2
368 : blume 844 [1997-01-29]
369 :     Changes to the SML/NJ system (available in 109.25) now make it possible
370 :     to use the top-level print function in CML programs (it gets dynamically
371 :     rebound to CML's version of TextIO.print when a CML program starts running).
372 : monnier 2
373 : blume 844 [1997-01-27]
374 :     Renamed CML.atEvt to CML.atTimeEvt.
375 : monnier 2
376 : blume 844 [1997-01-26]
377 :     Added SimpleRPC:SIMPLE_RPC to the CML library.
378 : monnier 2
379 : blume 844 [1997-01-26]
380 :     Fixed a bug in the I/O manager for the case when two I/O events became
381 :     enabled for the same thread at the same time.
382 : monnier 2
383 :    
384 :     Version 1.0.1 (SML/NJ 109.22)
385 :     -----------------------------
386 :    
387 : blume 844 [1996-11-09]
388 :     Added UnixEnv:UNIX_ENV to the structures reexported from the CML library.
389 : monnier 2
390 : blume 844 [1996-11-07]
391 :     Fixed bug in {TextIO,BinIO}.StreamIO.endOfStream, where more m-variable
392 :     was getting multiple puts.
393 : monnier 2

395 :     Version 1.0 (SML/NJ 109.21.1)
396 :     -----------------------------
397 :    
398 : blume 844 [1996-11-01]
399 :     Added version and banner to CML structure.
400 : monnier 2
401 : blume 844 [1996-11-01]
402 :     Added CML version of Unix structure.
403 : monnier 2
404 : blume 844 [1996-11-01]
405 :     Changed the implementation of the internal condition variables to make
406 :     them work correctly.
407 : monnier 2
408 : blume 844 [1996-11-01]
409 :     Added implementation of OS.IO.poll and OS.IO.pollEvt.
410 : monnier 2
411 : blume 844 [1996-11-01]
412 :     Fixed implementation of Socket.connect.
413 : monnier 2
