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

251 :
252 :			- Added version and banner to CML structure.
253 :			[1996-11-01]
254 :
255 :			- Added CML version of Unix structure.
256 :			[1996-11-01]
257 :
258 :			- Changed the implementation of the internal condition variables to make
259 :			them work correctly.
260 :			[1996-11-01]
261 :
262 :			- Added implementation of OS.IO.poll and OS.IO.pollEvt.
263 :			[1996-11-01]
264 :
265 :			- Fixed implementation of Socket.connect.
266 :			[1996-11-01]
