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