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