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