1 : monnier 2 This is a record of changes made to CML and the CML Library.
2 :     ------------------------------------------------------------
3 : jhr 1267
4 : jhr 1927 [2006-05-04]
5 :     Fixed bug with iGetPoll, mTakePoll, and mGetPoll. In some cases, the
6 :     atomic region was not being closed properly. The iGetPoll and mGetPoll
7 :     operations just read the value field now, since there is reads are
8 :     atomic.
9 :    
10 : jhr 1901 [2006-02-27]
11 :     Fixed bug with the combination of withNack and never, where the
12 :     negative acknowledgement is never generated. Thanks to Heath
13 :     Putnam for the bug report and fix.
14 :    
15 : mblume 1770 [2005-02-28]
16 :     Fixed serious bug in structure Atom. (Must use mvar, not mailbox!)
17 :    
18 : mblume 1759 [2005-02-24]
19 :     Reuse signature ATOM from $/smlnj-lib.cm, thus tracking all changes.
20 :     Implement structure Atom in terms of structure Atom in $/smlnj-lib.cm
21 :     by protecting access to the global hashtable using an mbox lock.
22 :     Atoms can now be created (sequentially) prior to calling RunCML.doit.
23 :    
24 : mblume 1717 [2004-11-24]
25 :     Made the IO implementation agnostic of size of Position.int.
26 :     (Now compiles with either Position = Int31 or Position = Int64.)
27 :    
28 : mblume 1389 [2003-09-23]
29 :     Accounted for changes to socket API in Basis. (Non-blocking
30 :     behavior is no longer a stateful property of a socket. Instead,
31 :     there are non-blocking versions of most functions in the
32 :     interface. This simplifies the CML code since it no longer
33 :     has to do OS-specific handling of "wouldblock" etc.
34 :     On the other hand, (trivial) CML implementations of those
35 :     non-blocking operations had to be added.)
36 :    
37 : mblume 1368 [2003-09-12]
38 :     Accounted for changed type of inputLine.
39 :    
40 : mblume 1354 [2003-09-09]
41 :     Made CML compile under Win32 again.
42 :    
43 : mblume 1350 [2003-09-03]
44 :     Added *_SLICE signatures and *Slice structures (copied from
45 :     "normal" Basis into CML Basis).
46 :     Fixed code broken due to API changes (slices).
47 :    
48 : jhr 1323 [2003-05-09]
49 :     Added the missing implementation of StreamIO event constructors
50 :     (e.g., TextIO.StreamIO.inputEvt). Note that if you use these
51 :     operations, then the system may not shutdown when all user threads
52 :     are blocked.
53 :    
54 : jhr 1322 [2003-04-21]
55 :     The CleanUp.logMailbox function was not protected against
56 :     interrupts (thanks to David Benson for catching this bug).
57 :    
58 : mblume 1320 [2003-04-09]
59 :     Changed the name of the directory cml-lib/cm to cml-lib/cm-descr
60 :     in order to avoid a name conflict with cml-lib/CM which gets
61 :     created by the compilation manager. (On case-insensitive
62 :     filesystems such as the one used by MacOS X the two names clash.)
63 :    
64 : jhr 1321 [2003-03-10]
65 :     Documentation cleanup.
66 :    
67 : jhr 1267 [2002-10-01]
68 :     Fixed a bad space leak in the stream I/O implementations. The
69 :     cleanup hooks were holding onto the initial buffer, which
70 :     meant that the entire buffer chain would remain live as long
71 :     as the stream was live.
72 :    
73 : blume 844 [2001-06-20]
74 :     Ported to SML/NJ 110.33 (in particular, the new CM).
75 :     Under the new CM, the CML library is known as $cml/cml.cm
76 :     and there is a CML-specific replacement for $/basis.cm
77 :     known as $cml/basis.cm. Two additional libraries
78 :     ($cml/cml-internal.cm and $cml/core-cml.cm) are used
79 :     internally but should not be referred to directly by client code.
80 :     A CML-specific replacement for $/smlnj-lib.cm is
81 :     known as $cml-lib/smlnj-lib.cm. The trace module is
82 :     $cml-lib/trace-cml.cm. (The aforementioned $cml/core-cml.cm
83 :     exists mainly to make it possible for $cml-lib/trace-cml.cm
84 :     to refer to it.)
85 : monnier 2
86 : blume 844 [2001-03-8]
87 :     Fixed a problem in the ordering of clean-up actions. IO streams
88 :     were being cleaned before servers, which meant that servers could
89 :     not use I/O in initialization or shutdown.
90 : monnier 167
91 : blume 844 [2001-01-14]
92 :     Fixed a bug in the timeout manager. Cleanup actions were being
93 :     executed twice, which breaks withNack.
94 : monnier 167
95 : blume 844 [2000-12-12]
96 :     Fixed a bug in the I/O manager (core-cml/io-manager.sml), where
97 :     if there were two threads blocked on the same descriptor (one
98 :     reading and one writing), the result might be matched to the
99 :     wrong thread.
100 :    
101 :     [2000-09-28]
102 :     Version 1.0.13 (SML/NJ Version 110.0.7)
103 :    
104 :     [2000-09-27]
105 :     Updated the CML Library to track additions to the SML/NJ Library.
106 :    
107 :     [1999-12-08]
108 :     Fixed a collection of bugs in event.sml related to the handling of
109 :     negative acknowledgements.
110 :    
111 :     [1999-12-01]
112 :     Modified RunCML.doit to install a dummy print hook. This prevents
113 :     the bug of SML/NJ's print function being called during CML execution
114 :     (the CML print function is installed by code in TextIO, but that
115 :     code isn't loaded by CML when the application does not specifically
116 :     mention TextIO).
117 :    
118 :     Version 1.0.12 (SML/NJ 110.0.6 and 110.8)
119 : monnier 139 -----------------------------------------
120 : monnier 106
121 : blume 844 [1999-09-29]
122 :     Updated the CML Library to track additions to the SML/NJ Library.
123 : monnier 139
124 : blume 844 [1999-07-05]
125 :     Added support for Win32 sockets (thanks to Riccardo Pucella).
126 : monnier 139
127 : blume 844 [1998-08-04]
128 :     Added preliminary Win32 implementation (thanks to Riccardo Pucella).
129 : monnier 106
130 : blume 844 [1998-06-01]
131 :     Fixed type of inputLineEvt in CML_TEXT_STREAM_IO (thanks to A. Appel).
132 : monnier 106
133 : blume 844 [1998-03-12]
134 :     Fixed bug in ChanIOFn (failure to spawn threads).
135 :    
136 :    
137 : monnier 8 Version 1.0.11 (SML/NJ 109.33 and 110)
138 :     --------------------------------------
139 :    
140 : blume 844 [1997-11-21]
141 :     Added TextIO.scanStream function.
142 : monnier 8
143 : blume 844 [1997-11-21]
144 :     Added import of PathUtil:PATH_UTIL to CML library.
145 : monnier 8
146 :    
147 :     Version 1.0.10 (SML/NJ 109.32)
148 :     ------------------------------
149 :    
150 : blume 844 [1997-09-18]
151 :     Fixed a scheduler bug that occured when the atomicState was SignalPending
152 :     and atomicSwitchTo was used to exit the atomic region.
153 : monnier 8
154 : blume 844 [1997-09-15]
155 :     Fixed a bug in the RunCML.doit code that prevented multiple runs (this bug
156 :     was exposed by the previous bug fix).
157 : monnier 8
158 : blume 844 [1997-09-15]
159 :     Fixed a serious bug with the internal condition variables (Event.atomicCVarSet
160 :     was not changing the state of the variable).
161 : monnier 8
162 : blume 844 [1997-09-15]
163 :     Introduced datatype rebinding to eliminate some structure opening.
164 : monnier 8
165 : blume 844 [1997-09-14]
166 :     Moved definition of tidToString to RepTypes, so that it can be used in
167 :     debugging the CML internals.
168 : monnier 8
169 : blume 844 [1997-09-12]
170 :     Server initialization/shutdown is now handled by a dedicated cleanup
171 :     routine. Eventually, each server should define its own cleanup routine,
172 :     and we'll get rid of logServer.
173 : monnier 8
174 : blume 844 [1997-09-12]
175 :     Fixed bugs in the initialization and shutdown protocols for the standard
176 :     text streams.
177 : monnier 8
178 :    
179 : monnier 2 Version 1.0.9 (SML/NJ 109.31)
180 :     -----------------------------
181 :    
182 : blume 844 [1997-09-02]
183 :     Added cleanup code for the I/O stacks (including the standard I/O streams).
184 : monnier 2
185 : blume 844 [1997-08-29]
186 :     Implemented a clean-up mechansim that is similar to that provided by
187 :     SML/NJ. The logging of global servers for initialization/shutdown
188 :     is now done using cleaners, which provide somewhat finer control.
189 :     Channel and mailbox logging is still supported, but the initialization
190 :     is done by a dedicated cleaner. This change is part of the overhaul
191 :     of RunCML.
192 : monnier 2
193 : blume 844 [1997-08-28]
194 :     Qualified the use of the "cont" type constructor, which is no longer
195 :     available at top level.
196 : monnier 2
197 : blume 844 [1997-08-28]
198 :     Replaced a few holdover uses of "abstraction" with opaque signature matching.
199 : monnier 2
200 : blume 844 [1997-08-15]
201 :     RunCML.doit now returns an OS.Process.status value. If a CML program
202 :     uses OS.Process.{exit,terminate} to shutdown, then the status argument
203 :     is returned as the result. If the system shuts down because of deadlock,
204 :     the OS.Process.failure is returned.
205 : monnier 2
206 : blume 844 [1997-08-15]
207 :     Many changes to ensure that exportFn images do not include the entire
208 :     top-level environment. These include: using SMLofNJ.isolate to create
209 :     top-level continuations, and reimplementing RunCML.exportFn to do better
210 :     housekeeping. To get this to work also required a number of changes
211 :     to the SML/NJ sources.
212 : monnier 2
213 : blume 844 [1997-08-15]
214 :     Fixed bug in scheduler, where a timer interrupt in an atomic region
215 :     was not getting marked by SignalPending.
216 : monnier 2
217 : blume 844 [1997-07-24]
218 :     The TextIO.output* functions did not implement line buffering; this
219 :     has now been added.
220 : monnier 2
221 :    
222 :     Version 1.0.8 (SML/NJ 109.30)
223 :     -----------------------------
224 :    
225 : blume 844 [1997-07-11]
226 :     Changed uses of System.Unsafe to Unsafe.
227 : monnier 2
228 : blume 844 [1997-07-11]
229 :     Eliminated redefinition of Scheduler structure to avoid loss of inlining,
230 :     since the compiler handles this properly now.
231 : monnier 2
232 : blume 844 [1997-07-11]
233 :     Added Atom.atom' (tracking SML/NJ library changes)
234 : monnier 2
235 : blume 844 [1997-06-30]
236 :     Removed Array2:ARRAY2 from library, as this is now gone from the
237 :     SML/NJ library.
238 : monnier 2
239 :    
240 :     Version 1.0.7 (SML/NJ 109.29)
241 :     -----------------------------
242 :    
243 : blume 844 [1997-06-11]
244 :     Changed OS.IO.{pollErr,isErr} to OS.IO.{pollPri,isPri} (this tracks fixes
245 :     in the SML/NJ implementation of the SML Basis Library.
246 : monnier 2
247 : blume 844 [1997-06-11]
248 :     Changes to src/Unix/posix-bin-prim-io.sml to track basis fixes.
249 : monnier 2
250 :    
251 :     Version 1.0.6 (SML/NJ 109.28)
252 :     -----------------------------
253 :    
254 : blume 844 [1997-05-21]
255 :     Added a temporary fix so that input operations do not cause the whole
256 :     CML system to block waiting for input. Eventually, there should be a
257 :     CML version of the complete Posix API, which is the right way to avoid
258 :     this problem.
259 : monnier 2
260 : blume 844 [1997-05-21]
261 :     Added RunCML.exportFn.
262 :     NOTE: there are some problems with the size of exported images that
263 :     need to be tracked down and fixed.
264 : monnier 2
265 :    
266 :     Version 1.0.5 (SML/NJ 109.26)
267 :     -----------------------------
268 :    
269 : blume 844 [1997-03-18]
270 :     Added SyncVar.{mSwap,mSwapEvt} operations, and changed the implementation
271 :     of multicast channels to use it.
272 : monnier 2
273 : blume 844 [1997-03-17]
274 :     Modified SyncVar.{mGet,mGetEvt} to resume other blocked threads (just
275 :     as iGet does).
276 : monnier 2
277 : blume 844 [1997-03-16]
278 :     Fixed a bug in SyncVar.{mTake,mTakeEvt}, where the cell was not getting
279 :     emptied in some execution paths.
280 : monnier 2
281 : blume 844 [1997-03-15]
282 :     Added an "error thread," which is enqueued when CML is not running.
283 :     This thread will get dispatched if someone tries to execute a CML
284 :     operation without using RunCML.doit (not including channel allocation,
285 :     etc.). I also added a top-level call to Scheduler.reset, which will
286 :     ensure that the current thread ID is initialized.
287 : monnier 2
288 : blume 844 [1997-03-13]
289 :     Fixed a serious bug in SyncVar.{iPut,mPut}, where the cell was not
290 :     getting filled in some cases.
291 : monnier 2
292 :    
293 :     Version 1.0.4 (SML/NJ 109.25.2)
294 :     -------------------------------
295 :    
296 : blume 844 [1997-02-28]
297 :     Added some additional modules to the CML Library: IOUtil:IO_UTIL and
298 :     KeywordsFn. These were recent additions to the SML/NJ Library. I also
299 :     reorganized the directory structure of the CML library to make it easier
300 :     to track changes in the SML/NJ Library.
301 : monnier 2
302 : blume 844 [1997-02-28]
303 :     Tracked changes in location of continuation operations changed in SML/NJ.
304 : monnier 2
305 :    
306 :     Version 1.0.3 (SML/NJ 109.25.1)
307 :     -------------------------------
308 :    
309 : blume 844 [1997-02-25]
310 :     Fixed bugs in the implementation of the pauseHook and schedulerHook in
311 :     RunCMLFn (missing atomicBegin).
312 : monnier 2
313 : blume 844 [1997-02-25]
314 :     Fixed bug in implementation of TraceCML when TraceToFile was set as the
315 :     destination.
316 : monnier 2
317 : blume 844 [1997-02-18]
318 :     Fixed bug in random access support in BinIOFn and TextIOFn (bug also in
319 :     SML/NJ implementation).
320 : monnier 2
321 : blume 844 [1997-02-17]
322 :     Added logging/unlogging for global mailboxes.
323 : monnier 2
324 : blume 844 [1997-02-17]
325 :     Fixed bug in the TraceCML.unwatchThread. Also changed the implementation
326 :     to avoid potential races between unwatching a thread and its termination.
327 : monnier 2
328 : blume 844 [1997-02-15]
329 :     Various changes to the Scheduler module to improve robustness. Added
330 :     an exception handler around the function in enqueueTmpThread. Replaced
331 :     enqueueCurThread with enqueueAndSwitchCurThread, which keeps the thread
332 :     ID bookkeeping in the same place. And fixed a bug(?) where atomicSwitchTo
333 :     was failing to set the current thread ID properly.
334 : monnier 2
335 : blume 844 [1997-02-04]
336 :     Added sendPoll operation on channels to CML structure.
337 : monnier 2
338 :    
339 :     Version 1.0.2 (SML/NJ 109.25)
340 :     -----------------------------
341 :    
342 : blume 844 [1997-01-30]
343 :     Added documentation for the Multicast and TraceCML library modules.
344 : monnier 2
345 : blume 844 [1997-01-30]
346 :     Made minor improvements to the implementation of TraceCML.
347 : monnier 2
348 : blume 844 [1997-01-29]
349 :     Changes to the SML/NJ system (available in 109.25) now make it possible
350 :     to use the top-level print function in CML programs (it gets dynamically
351 :     rebound to CML's version of TextIO.print when a CML program starts running).
352 : monnier 2
353 : blume 844 [1997-01-27]
354 :     Renamed CML.atEvt to CML.atTimeEvt.
355 : monnier 2
356 : blume 844 [1997-01-26]
357 :     Added SimpleRPC:SIMPLE_RPC to the CML library.
358 : monnier 2
359 : blume 844 [1997-01-26]
360 :     Fixed a bug in the I/O manager for the case when two I/O events became
361 :     enabled for the same thread at the same time.
362 : monnier 2
363 :    
364 :     Version 1.0.1 (SML/NJ 109.22)
365 :     -----------------------------
366 :    
367 : blume 844 [1996-11-09]
368 :     Added UnixEnv:UNIX_ENV to the structures reexported from the CML library.
369 : monnier 2
370 : blume 844 [1996-11-07]
371 :     Fixed bug in {TextIO,BinIO}.StreamIO.endOfStream, where more m-variable
372 :     was getting multiple puts.
373 : monnier 2
374 :    
375 :     Version 1.0 (SML/NJ 109.21.1)
376 :     -----------------------------
377 :    
378 : blume 844 [1996-11-01]
379 :     Added version and banner to CML structure.
380 : monnier 2
381 : blume 844 [1996-11-01]
382 :     Added CML version of Unix structure.
383 : monnier 2
384 : blume 844 [1996-11-01]
385 :     Changed the implementation of the internal condition variables to make
386 :     them work correctly.
387 : monnier 2
388 : blume 844 [1996-11-01]
389 :     Added implementation of OS.IO.poll and OS.IO.pollEvt.
390 : monnier 2
391 : blume 844 [1996-11-01]
392 :     Fixed implementation of Socket.connect.
