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