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