1 :	monnier	2	This is a record of changes made to CML and the CML Library.
2 :			------------------------------------------------------------
3 :
4 :	monnier	167	Version 1.0.13 (SML/NJ 110.9)
5 :			-----------------------------
6 :
7 :			- Changes to I/O APIs to track basis changes (deleted in_pos support
8 :			and changed type of StreamIO.mkInstream).
9 :			[1998-10-16]
10 :
11 :	monnier	139	Version 1.0.12 (SML/NJ 110.0.4 and 110.8)
12 :			-----------------------------------------
13 :	monnier	106
14 :	monnier	139	- Added preliminary Win32 implementation.
15 :			[1998-08-04]
16 :
17 :			- Fixed type of inputLineEvt in CML_TEXT_STREAM_IO (thanks to A. Appel).
18 :			[1998-06-01]
19 :
20 :	monnier	106	- Fixed bug in ChanIOFn (failure to spawn threads).
21 :			[1998-03-12]
22 :
23 :
24 :	monnier	8	Version 1.0.11 (SML/NJ 109.33 and 110)
25 :			--------------------------------------
26 :
27 :			- Added TextIO.scanStream function.
28 :			[1997-11-21]
29 :
30 :			- Added import of PathUtil:PATH_UTIL to CML library.
31 :			[1997-11-21]
32 :
33 :
34 :			Version 1.0.10 (SML/NJ 109.32)
35 :			------------------------------
36 :
37 :			- Fixed a scheduler bug that occured when the atomicState was SignalPending
38 :			and atomicSwitchTo was used to exit the atomic region.
39 :			[1997-09-18]
40 :
41 :			- Fixed a bug in the RunCML.doit code that prevented multiple runs (this bug
42 :			was exposed by the previous bug fix).
43 :			[1997-09-15]
44 :
45 :			- Fixed a serious bug with the internal condition variables (Event.atomicCVarSet
46 :			was not changing the state of the variable).
47 :			[1997-09-15]
48 :
49 :			- Introduced datatype rebinding to eliminate some structure opening.
50 :			[1997-09-15]
51 :
52 :			- Moved definition of tidToString to RepTypes, so that it can be used in
53 :			debugging the CML internals.
54 :			[1997-09-14]
55 :
56 :			- Server initialization/shutdown is now handled by a dedicated cleanup
57 :			routine. Eventually, each server should define its own cleanup routine,
58 :			and we'll get rid of logServer.
59 :			[1997-09-12]
60 :
61 :			- Fixed bugs in the initialization and shutdown protocols for the standard
62 :			text streams.
63 :			[1997-09-12]
64 :
65 :
66 :	monnier	2	Version 1.0.9 (SML/NJ 109.31)
67 :			-----------------------------
68 :
69 :			- Added cleanup code for the I/O stacks (including the standard I/O streams).
70 :			[1997-09-02]
71 :
72 :			- Implemented a clean-up mechansim that is similar to that provided by
73 :			SML/NJ. The logging of global servers for initialization/shutdown
74 :			is now done using cleaners, which provide somewhat finer control.
75 :			Channel and mailbox logging is still supported, but the initialization
76 :			is done by a dedicated cleaner. This change is part of the overhaul
77 :			of RunCML.
78 :			[1997-08-29]
79 :
80 :			- Qualified the use of the "cont" type constructor, which is no longer
81 :			available at top level.
82 :			[1997-08-28]
83 :
84 :			- Replaced a few holdover uses of "abstraction" with opaque signature matching.
85 :			[1997-08-28]
86 :
87 :			- RunCML.doit now returns an OS.Process.status value. If a CML program
88 :			uses OS.Process.{exit,terminate} to shutdown, then the status argument
89 :			is returned as the result. If the system shuts down because of deadlock,
90 :			the OS.Process.failure is returned.
91 :			[1997-08-15]
92 :
93 :			- Many changes to ensure that exportFn images do not include the entire
94 :			top-level environment. These include: using SMLofNJ.isolate to create
95 :			top-level continuations, and reimplementing RunCML.exportFn to do better
96 :			housekeeping. To get this to work also required a number of changes
97 :			to the SML/NJ sources.
98 :			[1997-08-15]
99 :
100 :			- Fixed bug in scheduler, where a timer interrupt in an atomic region
101 :			was not getting marked by SignalPending.
102 :			[1997-08-15]
103 :
104 :			- The TextIO.output* functions did not implement line buffering; this
105 :			has now been added.
106 :			[1997-07-24]
107 :
108 :
109 :			Version 1.0.8 (SML/NJ 109.30)
110 :			-----------------------------
111 :
112 :			- Changed uses of System.Unsafe to Unsafe.
113 :			[1997-07-11]
114 :
115 :			- Eliminated redefinition of Scheduler structure to avoid loss of inlining,
116 :			since the compiler handles this properly now.
117 :			[1997-07-11]
118 :
119 :			- Added Atom.atom' (tracking SML/NJ library changes)
120 :			[1997-07-11]
121 :
122 :			- Removed Array2:ARRAY2 from library, as this is now gone from the
123 :			SML/NJ library.
124 :			[1997-06-30]
125 :
126 :
127 :			Version 1.0.7 (SML/NJ 109.29)
128 :			-----------------------------
129 :
130 :			- Changed OS.IO.{pollErr,isErr} to OS.IO.{pollPri,isPri} (this tracks fixes
131 :			in the SML/NJ implementation of the SML Basis Library.
132 :			[1997-06-11]
133 :
134 :			- Changes to src/Unix/posix-bin-prim-io.sml to track basis fixes.
135 :			[1997-06-11]
136 :
137 :
138 :			Version 1.0.6 (SML/NJ 109.28)
139 :			-----------------------------
140 :
141 :			- Added a temporary fix so that input operations do not cause the whole
142 :			CML system to block waiting for input. Eventually, there should be a
143 :			CML version of the complete Posix API, which is the right way to avoid
144 :			this problem.
145 :			[1997-05-21]
146 :
147 :			- Added RunCML.exportFn.
148 :			NOTE: there are some problems with the size of exported images that
149 :			need to be tracked down and fixed.
150 :			[1997-05-21]
151 :
152 :
153 :			Version 1.0.5 (SML/NJ 109.26)
154 :			-----------------------------
155 :
156 :			- Added SyncVar.{mSwap,mSwapEvt} operations, and changed the implementation
157 :			of multicast channels to use it.
158 :			[1997-03-18]
159 :
160 :			- Modified SyncVar.{mGet,mGetEvt} to resume other blocked threads (just
161 :			as iGet does).
162 :			[1997-03-17]
163 :
164 :			- Fixed a bug in SyncVar.{mTake,mTakeEvt}, where the cell was not getting
165 :			emptied in some execution paths.
166 :			[1997-03-16]
167 :
168 :			- Added an "error thread," which is enqueued when CML is not running.
169 :			This thread will get dispatched if someone tries to execute a CML
170 :			operation without using RunCML.doit (not including channel allocation,
171 :			etc.). I also added a top-level call to Scheduler.reset, which will
172 :			ensure that the current thread ID is initialized.
173 :			[1997-03-15]
174 :
175 :			- Fixed a serious bug in SyncVar.{iPut,mPut}, where the cell was not
176 :			getting filled in some cases.
177 :			[1997-03-13]
178 :
179 :
180 :			Version 1.0.4 (SML/NJ 109.25.2)
181 :			-------------------------------
182 :
183 :			- Added some additional modules to the CML Library: IOUtil:IO_UTIL and
184 :			KeywordsFn. These were recent additions to the SML/NJ Library. I also
185 :			reorganized the directory structure of the CML library to make it easier
186 :			to track changes in the SML/NJ Library.
187 :			[1997-02-28]
188 :
189 :			- Tracked changes in location of continuation operations changed in SML/NJ.
190 :			[1997-02-28]
191 :
192 :
193 :			Version 1.0.3 (SML/NJ 109.25.1)
194 :			-------------------------------
195 :
196 :			- Fixed bugs in the implementation of the pauseHook and schedulerHook in
197 :			RunCMLFn (missing atomicBegin).
198 :			[1997-02-25]
199 :
200 :			- Fixed bug in implementation of TraceCML when TraceToFile was set as the
201 :			destination.
202 :			[1997-02-25]
203 :
204 :			- Fixed bug in random access support in BinIOFn and TextIOFn (bug also in
205 :			SML/NJ implementation).
206 :			[1997-02-18]
207 :
208 :			- Added logging/unlogging for global mailboxes.
209 :			[1997-02-17]
210 :
211 :			- Fixed bug in the TraceCML.unwatchThread. Also changed the implementation
212 :			to avoid potential races between unwatching a thread and its termination.
213 :			[1997-02-17]
214 :
215 :			- Various changes to the Scheduler module to improve robustness. Added
216 :			an exception handler around the function in enqueueTmpThread. Replaced
217 :			enqueueCurThread with enqueueAndSwitchCurThread, which keeps the thread
218 :			ID bookkeeping in the same place. And fixed a bug(?) where atomicSwitchTo
219 :			was failing to set the current thread ID properly.
220 :			[1997-02-15]
221 :
222 :			- Added sendPoll operation on channels to CML structure.
223 :			[1997-02-04]
224 :
225 :
226 :			Version 1.0.2 (SML/NJ 109.25)
227 :			-----------------------------
228 :
229 :			- Added documentation for the Multicast and TraceCML library modules.
230 :			[1997-01-30]
231 :
232 :			- Made minor improvements to the implementation of TraceCML.
233 :			[1997-01-30]
234 :
235 :			- Changes to the SML/NJ system (available in 109.25) now make it possible
236 :			to use the top-level print function in CML programs (it gets dynamically
237 :			rebound to CML's version of TextIO.print when a CML program starts running).
238 :			[1997-01-29]
239 :
240 :			- Renamed CML.atEvt to CML.atTimeEvt.
241 :			[1997-01-27]
242 :
243 :			- Added SimpleRPC:SIMPLE_RPC to the CML library.
244 :			[1997-01-26]
245 :
246 :			- Fixed a bug in the I/O manager for the case when two I/O events became
247 :			enabled for the same thread at the same time.
248 :			[1997-01-26]
249 :
250 :
251 :			Version 1.0.1 (SML/NJ 109.22)
252 :			-----------------------------
253 :
254 :			- Added UnixEnv:UNIX_ENV to the structures reexported from the CML library.
255 :			[1996-11-09]
256 :
257 :			- Fixed bug in {TextIO,BinIO}.StreamIO.endOfStream, where more m-variable
258 :			was getting multiple puts.
259 :			[1996-11-07]
260 :
261 :
262 :			Version 1.0 (SML/NJ 109.21.1)
263 :			-----------------------------
264 :
265 :			- Added version and banner to CML structure.
266 :			[1996-11-01]
267 :
268 :			- Added CML version of Unix structure.
269 :			[1996-11-01]
270 :
271 :			- Changed the implementation of the internal condition variables to make
272 :			them work correctly.
273 :			[1996-11-01]
274 :
275 :			- Added implementation of OS.IO.poll and OS.IO.pollEvt.
276 :			[1996-11-01]
277 :
278 :			- Fixed implementation of Socket.connect.
279 :			[1996-11-01]
