Details about the relationship of each component to the previous release and pointers to documentation and DF files appear in the "Summary of Release Components" section, below. The components whose names are preceded by an asterisk can be ignored by the casual Cedar user. *AlpineStubs *New* *AlpineUser *New* *AMEvents *Changed* Implementation in boot file AMModel *Changed* Implementation in boot file AMProcess *New* Implementation in boot file AMTypes *Changed* Implementation in boot file *BasicHeads *Changed* Implementation in boot file BBV *Changed* Implementation in boot file *BCD Binder *Booting *New* Implementation in boot file BootTool *New* Implementation in boot file BravoToTioga *Changed* *BTrees BugBane *Changed* Implementation in boot file *CedarDB *Withdrawn* Replaced by Cypress CedarReals Implementation in boot file CedarRoot *Changed* Implementation in boot file CedarScanner *New* Implementation in boot file CedarSnapshot *Changed* Implementation in boot file Chat *Changed* *CIFSCommands *Changed* CIFS *Changed* Implementation in boot file ClientFileTool *Changed* Clock *Changed* CoFork *Changed* *ColorPackage Implementation in boot file *Communication Implementation in boot file *CompatibilityPackage *Changed* Implementation in boot file Compiler Cypress *New* *D0Microcode DateAndTime *Changed* Implementation in boot file DebugTool *New* DFFiles *Changed* *DLionMicrocode *DoradoMicrocode *Changed* FileTool *Changed* Implementation in boot file FlushUnneededTempFiles *Changed* FootBall *New* Forms *Changed* *Germ *Changed* Separate boot file GrapevineUser Implementation in boot file Graphics Implementation in boot file *IFSFile IncludeChecker *Changed* *Inscript *Changed* Implementation in boot file IO *Changed* Implementation in boot file *Lister ListsAndAtoms *Changed* Implementation in boot file *Loader *Changed* Implementation in boot file Lupine *Changed* Maintain *Changed* *MakeBoot *Changed* MCross *Changed* *MesaScanner *Withdrawn* Subsumed by CedarScanner Modeller *Changed* NewStuff *Changed* OnlineMergeSort Othello *Changed* Separate boot file *Packager PerfStats *Changed* *PGS *PilotKernel *Changed* Implementation in boot file *Pine *Withdrawn* PlotPackage *Changed* Poplar *Changed* Print *Changed* Pup *Changed* Implementation in boot file *Pupwatch *Changed* Random RedBlackTree RedBlackTreeRef *Changed* Reminder *Changed* Rigging Implementation in boot file *RPCRuntime *Changed* Implementation in boot file SafeStorage *Changed* Implementation in boot file SampleTool *Changed* Scaled *New* ScanZones *New* *Sequin Set *Changed* SirPress *Changed* SpaceWatch *New* *SpecialTerminal *Changed* Implementation in boot file Spell *New* Implementation in boot file Spy *Changed* Squirrel *Changed* STP *New* STPServer Talker *New* Tank *New* *TerminalMultiplex *Changed* Implementation in boot file Tioga *Changed* Implementation in boot file TJaMGraphics *Withdrawn* TSetter *Changed* *TTYIO *Changed* Implementation in boot file UECP Unique *Changed* *UserCredentials *Changed* Implementation in boot file UserExec *Changed* Implementation in boot file UserProfile *New* Implementation in boot file *VersionMap *Changed* Implementation in boot file *VersionMapBuilder *Changed* Viewers *Changed* Implementation in boot file ViewRec *Changed* VTables *Changed* Walnut *Changed* WalnutSend *Withdrawn* Subsumed by Walnut Watch *Changed* Waterlily *Changed* *WorldVM *Changed* Implementation in boot file Summary of Release Components ------------------------------- Note: In the descriptions that follow, unless otherwise specified, the DF file or files for a component are located on [Indigo]Top>. If the documentation file name is not a path, it is assumed to be accessible using the DF file name and BringOver, i.e., BringOver /o DocFileName DFFileName In general, documentation is stored on [Indigo]Documentation>ComponentName.press but there are occasional exceptions. AlpineStubs ------------------ DF file: AlpineStubs.df Documentation: contact implementor Implementor: MBrown This new component contains client stubs for the public Alpine interfaces. AlpineUser ------------------ DF file: AlpineUser.df Documentation: contact implementor Implementor: MBrown This new component is for use by testers of the Alpine file server. At present, Alpine is being used for storage of databases that have an independent backup mechanism; Walnut databases are an example. Contact the implementor if you are interested in using Alpine. AMEvents ---------- DF file: AMEvents.df Documentation: None - consult implementor before using Implementor: Andrew Birrell Bug fixes, implementing remote calls, implementing outload-before-boot in world-swap debugger.. AMModel ---------- DF file: AMModel.df Documentation: (See AMModel.mesa) Implementor: Rovner Bugfixes and recompilation. AMProcess ------------------ DF file: AMProcess.df Documentation: None - consult AMProcess.mesa or implementor Implementor: Andrew Birrell This package provide access at the level of the Cedar abstract machine to parallel processes. These may be processes in the current execution environment, or processes in a world-swap- or tele- debuggee. Processes may be stopped ("frozen") at arbitrary points in their execution, and frozen parts of processes may be examined. See the DebugTool for user interfaces to these facilities. AMTypes ---------- DF file: AMTypes.df Documentation: RTTypes.tioga, .press (NOT up to date yet) Implementor: Rovner Major overhaul of the implementation to accommodate arms-length (i.e. worldswap and across the net) debugging using Cedar. Major overhaul to the symbol table access stuff to facilitate bootstrapping (in preparation for future releases). Overhaul of the symbol table caching algorithm to minimize VM fragmentation. Various bug fixes and performance and feature enhancements to accommodate the interpreter. BasicHeads ---------- DF file: [Indigo]Heads>BasicHeadsCommon.df [Indigo]Heads>BasicHeadsDorado.df [Indigo]Heads>BasicHeadsD0.df [Indigo]Heads>BasicHeadsDLion.df Documentation: See interfaces Implementor: Taft The BasicHeads now export two new interfaces (both obtained via PilotInterfaces.df). IntervalTimerFace provides the ability to wait for specific time intervals at a much higher resolution than is possible using condition variable timeouts or display refresh wakeups. DisplayFaceExtras provides a way to change the display refresh rate (e.g., to 60 hz. for compatibility with video tape equipment). Both these interfaces do useful things only on a Dorado; the Dolphin and Dandelion versions are dummy. The Dorado BasicHeads can now operate multiple (up to 15) disk drives, including any mixture of T-80s and T-300s. BBV ---- DF file: BBV.df Documentation: BBV.doc Implementor: Atkinson The 'openr' and 'findr' commands have been incorporated into BBV. BBV no longer has an icon by default (use the 'bbv' command to get it if desired). Minor bugs have been fixed as well. BCD ---- DF file: BCD.df Documentation: contact implementor Implementor: Satterthwaite Unchanged from previous release. Binder ------ DF file: Binder.df Documentation: see Mesa 5.0 Reference Manual and Mesa User's Handbook Implementor: Satterthwaite Unchanged from previous release. BootTool ------------------ DF file: BootTool.df Documentation: Cedar Manual Implementor: Levin The Boot Tool enhances the functionality previously available through the "Boot" button at the top right of the Cedar display. It is invoked by right-clicking "Boot" , which produces a viewer at the top of the right column. Left- and middle-clicking preserve most of the old behavior of the "Boot" button. The top menu in this viewer represents most of booting situations you will need: Boot from specific logical volume "Boot Button" (i.e., boot physical volume; Dorado triple-boot without keys) Boot Alto emulator (from network) Boot BasicCedarDorado.boot (for implementors only) The logical volume buttons may incorporate switches. If you have a volume named Gorp and you want the R, W, and Z switches to be used when booting Gorp, include one of the following equivalent lines in your profile: GorpSwitches: RWZ Boot.GorpSwitches: RWZ The menu button will appear as Gorp/RWZ to remind you of the switches that will be used. (Implementors only: the FileSwitches profile entry is still interpreted by the "Basic" menu button.) The second menu line contains two buttons, "Boot" (guarded) and "Reset", which are used in conjunction with the remaining sections of the viewer. The area of the viewer labelled "Booting Sources" has four (mutually exclusive) buttons to select a particular class of booting: Volume - boots a logical volume File - boots a named file (not necessarily on the system volume) Microcode - boots a specific microcode emulator from the Ethernet PhysicalVolume - boots a physical volume (today, we have only one) Following each button is a text viewer that displays an instance within a booting class, e.g., for "Volume", the name of a logical volume. The Boot Tool can discover all possible logical and physical volumes available for booting, and can find most "File" and "Microcode" instances. To see all instances of a class that the Boot Tool knows about, repeatedly left-click the class button. You can alter the "File" and "Microcode" sources simply by editing the appropriate text field, but you should rarely have to do so. Most of the booting classes accept booting switches. The lower section labelled "Booting Options" contains a place to supply switches. Note that these switches are NOT interpreted by the menu buttons on the first line (see above). To initiate booting, select the desired class button and instance, then click the "Boot" menu item. If you get hopelessly confused, click "Reset" to return the tool to its original state. Alternatively, you can destroy the viewer and click the "Boot" button at the top of the screen. The Boot Tool will refuse to boot if you have unsaved viewers. BravoToTioga ------------- DF file: BravoToTioga.df Documentation: See package catalog entry Implementor: Plass Fixed to accommodate changes to IO and UserExec, command line syntax embellished to accommodate "new _ old" form. BTrees ------ DF file: BTrees.df Documentation: contact implementor Implementor: Levin Unchanged from previous release. BugBane -------- DF file: BugBane.df Documentation: BugBane.doc Implementor: Atkinson Mostly just bug fixes, especially dealing with multiple worlds. All BugBane documentation is now in BugBane.doc. Cedar Reals ----------- DF file: CedarReals.df Documentation: MesaFloat60.press Implementor: Stewart No changes from Cedar 3.5 CedarRoot --------- DF file: CedarRoot.df Documentation: None Implementor: Levin Bug fixes only. CedarScanner -------------- DF file: CedarScanner.df Documentation: CedarScanner.mesa Implementor: Atkinson CedarScanner is a renamed version of MesaScanner. The input is now from a closure, rather than just a procedure (additional user data is the difference). CedarSnapshot -------------- DF file: CedarSnapshot.df Documentation: See comments in CedarSnapshot.mesa Implementor: Levin Bug fixes only. Chat ---- DF file: Chat.df Documentation: Chat.doc Implementor: Larry Stewart Differences from Cedar 3.5 Chat: Closing a chat viewer does not close an open connection. Typescript files now work. The Typescript viewers implementation will eventually truncate the visible, scrollable contents of the viewer, but the log file is never truncated. After you select a host name and bug Login or Open, the input focus is moved to the end of the viewer. Known bug: Do not create a checkpoint which includes an open chat window or a chat icon. The code is holding on to a streamhandle for the log file. CIFS, CIFSCommands ------------------ DF file: same Documentation: CIFS.mesa Implementor: Gifford, Schroeder Recompiled only ClientFileTool -------------- DF file: ClientFileTool.df Documentation: none Implementor: Andrew Birrell New release component. This tool provides facilities in a world-swap debugger for fetching files from the client world. The interface should be obvious. Clock ----- DF file: Clock.df Documentation: Clock.mesa Implementor: Atkinson No change. CoFork ------- DF file: CoFork.df Documentation: CoFork.press Implementor: Sturgis Recompilation. ColorPackage ------------- DF file: ColorPackage.df Documentation: See comments in ColorMap.mesa and ColorWorld.mesa Implementor: Maureen Stone Unchanged Communication --------------- DF file: Communication.df Documentation: Pilot Programmers' Guide and Pup package documentation Implementor: Birrell Unchanged from previous release. CompatibilityPackage -------------------- DF file: CompatibilityPackage.df Documentation: None Implementor: Levin Directory enumeration is twice as fast. Compiler -------- DF file: Compiler.df Documentation: Cedar7T11.press Implementor: Satterthwaite Unchanged from previous release. Cypress ------------------ DF file: Cypress.df Documentation: See implementor Implementor: Cattell Cypress replaces the CedarDB package of Cedar 3.5.2. It incorporates major interface changes, including a new more convenient scheme for properties and the introduction of segments so that applications need no longer share a single database. The most significant change in this release is extensive performance tuning, yielding improvements of a factor of 2 to 3 for the most common operations. Most of these operations now average under a millisecond. Zip, zip. Documentation of the new system is a constant week away from completion, but will now be receiving higher priority. D0Microcode ------------ DF file: D0Microcode.df Documentation: none Implementor: Fiala Unchanged from previous release. DateAndTime ------------- DF file: DateAndTime.df Documentation: See comments in DateAndTime.mesa Implementor: Levin Unchanged from previous release. DebugTool ------------------ DF file: DebugTool.df Documentation: Not yet available. Interim information is in [Indigo]DebugTool.txt Implementor: Andrew Birrell This tool provides a user interface to the facilities for debugging parallel processes. It also provides global control when using Cedar to debug another machine ("teledebugging") or to debug a suspended world on the same machine ("world-swap debugging"). Just give the command "DebugTool" to your userExec to get a tool for debugging processes in your current Cedar execution environment. Say "DebugTool machineName" to teledebug some other machine (this is available in your ordinary Cedar world, you don't need to be in a special debugger world). If you install a world-swap debugger, a DebugTool is automatically created for looking at the outloaded debuggee. DFFiles ------- DF file: DFFiles.DF Documentation: DFFilesRefMan.Press Implementor: Schmidt Large number of bugs fixed. No longer uses the Exec and TTY interfaces. Uses faster protocols for enumeration. DLionMicrocode --------------- DF file: DLionMicrocode.df Documentation: See implementor Implementor: Sturgis Unchanged from previous release. DoradoMicrocode ---------------- DF file: DoradoMicrocode.df Documentation: [Indigo]DoradoBooting.press; contact maintainer Implementor: Taft Changes in this version are required by the new BasicHeads for Cedar 4.0. FileTool -------- DF file: FileTool.df Documentation: UserExec FileTool? or Introduction To Cedar Implementor: Stewart No changes from Cedar 3.5 FlushUnneededTempFiles ------------------------- DF file: FlushUnneededTempFiles.df Documentation: None Implementor: Levin Recompilation only. Football ------------------ DF file: Football.df Documentation: Football.doc Implementor: Maxwell New Entry. Forms ------ DF file: Forms.df Documentation: Internal Implementor: Horning There is now a business letter form and a slide making form. Germ ----- DF files: GermDorado.df, GermD0.df Documentation: "Pilot User's Handbook" Implementor: Taft The Dorado Germ is rebuilt with current components (for the first time in 20 months), and fixes a timeout bug that was the cause of frequent 922 errors when loading Othello from the MesaNetExec. It is important that you install the new Germ on your disk (using Othello's Germ Fetch command) and re-boot CoPilot and Client volumes, even if you have already converted to 4.0 or aren't planning to convert for a while. This is because a mismatch between the net-bootable Germ and the one on your disk may result in great confusion when you run Othello from the MesaNetExec. GrapevineUser -------------- DF file: GrapevineUser.df Documentation: [Indigo]Docs>Grapevine.press and Interface.press Implementor: Birrell Unchanged from previous release. Graphics -------- DF file: Graphics.df Documentation: see comments in Graphics.mesa Implementor: Wyatt Unchanged from previous release. IFSFile ------ DF file: IFSFile.df Documentation: contact implementor Implementor: Levin Unchanged from previous release. IncludeChecker --------------- DF file: IncludeChecker.df Documentation: (SDD documentation) Implementor: Rovner Recompilation. Inscript ------- DF file: Inscript.df Documentation: InscriptImplAppendix.memo; InscriptImplementation.memo, .press Implementor: Maureen Stone, Dan Swinehart Recompiled part of implementation only IO, FileIO ---------------------- DF file: IO Documentation: IO.mesa OR [Indigo]Documentation>IO.press, FileIO.mesa OR [Indigo]Documentation>FileIO.press. Implementor: Teitelman, MBrown The section of IO dealing with parsing the input stream, i.e. GetRope, GetToken, GetRefAny, etc. has been completely reworked. A guide to how to convert from IO 3.5 to IO 4.0 is included at the end of IO.mesa. Conversion should be straightforward. The Cedar Scanner is now used by GetInt, GetReal, GetRefAny etc., so that expressions like 1.0E-04, etc. now read correctly. A new procedure GetCedarToken is available. Some procedures have been renamed or withdrawn. One problem however is that GetLine was accidentally left out of IO. It can be constructed using GetSequence, but the default behaviour of GetSequence is to read up to the CR and leave the CR in the buffer to be read by the next caller. Thus to implement the old GetLine one would have to call GetSequence and then do a GetChar to discard the CR. A version of GetLine that does this is provided as IOExtras.GetLine. *r, *t have been deimplemented as PF star procs. Use the corresponding \ character. *n means NewLine, i.e. if executed immediately following a CR is a NOP, otherwise outputs a CR. *l, which changes looks, is now a nop if the corresponding stream does not implement looks, rather than raising an error as it used. When an unimplemented * or % code is encountered, before raising the not implemented signal, pf will see if the backing stream implements this operation. This allows the user to put other streams, e.g. dribble streams, buffered streams, in front of the stream that implements a particular code. Lister ----- DF file: Lister.df Documentation: Lister.txt Implementor: Satterthwaite Unchanged from previous release. ListsAndAtoms -------------- DF file: ListsAndAtoms Documentation: See comments in Atom.mesa, List.mesa, RefTab.mesa Implementor: Teitelman No changes. Loader ------ DF file: Loader.df Documentation: See Loader.mesa Implementor: Paul Rovner Recompilation. Lupine ------- DF file: Lupine.df Documentation: LupineUsersGuide.press Implementor: Bruce Nelson (meanwhile, Andrew Birrell) Unchanged from previous release. Maintain --------- DF file: Maintain.df Documentation: Introduction to Cedar, [Indigo]Docs>Interface.press. Implementor: Andrew Birrell Now supports database enquiries with pattern matching on the name. For example, the "Type Summary" button for group "Cedar*.pa" will give you a summary of the groups CedarImplementors^.pa, CedarUsers^.pa, etc. The "Type Pattern" button just gives you the names that match the pattern. Type Pattern for group *.pa will tell you the names of all groups in the PA registry. Similarly for individuals. The pattern matching is slow and expensive in terms of server cycles - please use it sparingly. MakeBoot --------- DF file: MakeBoot.df Documentation: MakeBoot.press Implementor: Levin Unchanged from previous release. MCross ------- DF file: MCross.df Documentation: MCross.doc Implementor: Rovner Recompilation. Modeller -------- DF file: Modeller.DF Documentation: ModelRefMan.Press and see Satterthwaite or Schmidt Implementor: Satterthwaite Bug fixes and tweaking of the user interface. Some internal reorganization. NewStuff ------------------ DF file: NewStuff.df Documentation: [Indigo]Documentation>NewStuff.tioga Implementor: Warren Teitelman New Features: A facility for generating a log of all of the files that you save during a session is automatically enabled when NewStuffImpl is loaded, unless you have an entry in your user profile of the form CreateChangesLog: FALSE. This log is kept on the file Changes.Log which is created when it is first needed. Each time you save a file, the date, file name, and changes log entry that was inserted in your file via the facility Updating Changes Log discussed above, if there is such an entry, is added to this log. Whenever a Tioga document is searched via the Find, Word, or Def menu buttons, the target of the search is saved. If the target for this particular search, i.e. the current selection, is either empty (a point selection), or consists of a single character, then the previous target is used instead. This enables searching for Foo, deleting it, and then searching for the next Foo by simply clicking the menu button again. It also enables searching for a particular target, changing the input focus in order to type something somewhere else, for example, to obtain a new viewer and load it with a particular file, and then searching again without having to reselect the target. CTRL-Next has been changed so as not to delete any fields remaining in the template that do not have default values specified, since this would cause an error when the expression was interpreted. This will allow you to use ctrl-E to obtain a template for an object with a large number of fields, most of which are defaulted, type ctrl-NEXT to eliminate all of the defaulted fields, and then fill in the fields that remain. The viewers package allows you to load an existing viewer with a file while requesting that the current contents of the viewer be made iconic. This is accomplished by selecting the name of the file, and then right clicking get. NewStuff extends this feature to allow you to select an icon, and then right-click get in a viewer. This causes the icon to be opened in place of the viewer, and the viewer to be made iconic, i.e. the two are swapped. Similarly, selecting an icon and then middle clicking get will open the icon just below the viewer, and left clicking get will cause the icon to replace the viewer. OnlineMergeSort ---------------- DF file: OnlineMergeSort.df Documentation: see comments in interfaces Implementor: MBrown unchanged Othello ------- DF file: [Indigo]Othello>Othello.df Documentation: Introduction to Cedar; Pilot User's Handbook Implementor: Taft The Dorado version can now deal with hardware configurations that include multiple Trident disks, including T-300s. Packager -------- DF file: Packager.df Documentation: Pilot User's Handbook Implementor: Levin unchanged PerfStats ------------------ DF file: PerfStats.df Documentation: see comments in PerfStats.mesa Implementor: MBrown Bug fixes only PGS ---- DF file: [Indigo]PGS>PGS.df Documentation: contact implementor Implementor: Satterthwaite unchanged PilotKernel ---------- DF file: PilotInterfaces.df, [Indigo]Pilot>PilotKernel.df and UtilityPilotKernel.df Documentation: Pilot Programmer's Manual Implementor: Levin Performance enhancements; no functional changes PlotPackage ----------- DF file: PlotPackage.df Documentation: (see interfaces) Implementor: Rovner Recompilation. Poplar ------ DF file: Poplar.DF Documentation: Poplar.Press, EASPL.Press Implementor: Schmidt Recompilation only. Print ----- DF file: Print.df Documentation: Print.doc Implementor: Plass Changed to use default exec for feedback when printing the current selection. Known problems: Don't try to use Print while TSetter is sending something to the printer. PriorityQueue ------------- DF file: PriorityQueue.df Documentation: PriorityQueue.mesa Implementor: Atkinson Unchanged. Pup ---- DF file: Pup.df (most public interfaces are in Communication.df) Documentation: [Ivy]*Pup.press Implementor: Andrew Birrell Unchanged from previous release. Pupwatch --------- DF file: Pupwatch.df Documentation: [Indigo]Pupwatch>Pupwatch.press Implementor: Andrew Birrell DF file: [Indigo]Top>Pupwatch.df Documentation: [Indigo]Docs>Pupwatch.press Implementor: Andrew Birrell Now understands more of the RPC protocol; Destroy now works. Random ------- DF file: Random.df Documentation: Random.doc, Random.press Implementor: MBrown Unchanged RedBlackTree ------------- DF file: RedBlackTree.df Documentation: OrderedSymbolTable.press Implementor: MBrown Unchanged RedBlackTreeRef ------------------ DF file: [indigo]Top>RedBlackTreeRef.df Documentation: see comments in OrderedSymbolTableRef.mesa Implementor: MBrown Bug fixes only Reminder --------- DF file: Reminder.df Documentation: (See Reminder.mesa) Implementor: Rovner Recompilation only. Rigging ------- DF file: Rigging.df Documentation: Rope.tioga Implementor: Atkinson Unchanged. RPC Runtime ------------- DF file: RPCRuntime.df Documentation: LupineUsersGuide.press Implementor: Birrell Minor bug fixes SafeStorage ----------- DF file: SafeStorage.df Documentation: See [Indigo]Documentation>SafeStorage.press and SafeStoragePrimer.press Implementor: Rovner Internal overhaul for performance improvement. New instrumentation machinery for use by wizards. SampleTool ----------- DF file: [Indigo]Documentation>SampleTool.df Documentation: Self-documenting, with additonal comments in the Cedar Examples. Implementor: McGregor Recompilation. Scaled ---------- DF file: [Indigo]Top>Scaled.df Documentation: None Implementor: Michael Plass New. ScanZones ---------- DF file: ScanZones.df Documentation: This program is a performance analysis tool that is used by implementors for analyzing the utilization of storage acquired by NEW. See comments in ScanZones.mesa Implementor: Rovner Many small enhancements and new features. Sequin ------ DF file: Sequin.df Documentation: contact implementor Implementor: Levin Unchanged. Set --- DF file: Set.df Documentation: Set.doc Implementor: Rovner Recompilation only. SirPress ------- DF file: SirPress.df Documentation: see comments in SirPress.mesa, PressPrinter.mesa Implementor: Plass Minor bug fixes. SpaceWatch ------------------ DF file: [Indigo]Top>SpaceWatch.df Documentation: contact implementor Implementor: Maxwell New entry. (formerly part of Spy.df) SpecialTerminal --------------- DF file: SpecialTerminal.df Documentation: See implementor Implementor: Levin Unchanged. Spell, Generator ------------------ DF file: Spell.df Documentation: Spell.mesa or [Indigo]Documentation>Spell.press Implementor: Warren Teitelman Bug fixes. Spy --- DF file: Spy.df Documentation: Spy.doc Implementor: John Maxwell Some bug fixes. Improved format for the output. Squirrel ------------------ DF file: Squirrel.df Documentation: See implementor Implementor: Cattell, Donahue No major changes have been made to Squirrel for this release; it is included in the release to provide support for Walnut and Hickory. (This support dependency will be removed in the next release; Squirrel will provide only application-independent database tools). STP ------------------ DF file: STP.DF Documentation: none Implementor: Schmidt This release contains two versions of the STP interface. The Rubicon version is called "STP.Bcd" and contained in CompatibilityPackage.DF; a newer version is called "UnsafeSTP.Bcd" and is contained in STP.DF. The UnsafeSTP version will replace the old rubicon version in the 4.1 release. This new version speaks a new protocol that speeds long enumeration by as much as a factor of 5. It also uses LONG POINTERS instead of POINTERS, reducing MDS needs. To use it in 4.0, you must include the implementation module UnsafeSTPs.Bcd in your config and call UnsafeSTP instead of calling STP. See me for more details. STPServer --------- DF file: STPServer.DF Documentation: see package catalog Implementor: Schmidt Unchanged from previous release. Talker ------------------ DF file: Talker.df Documentation: See [Indigo]Documentation>Talker.doc. Implementor: Paul Rovner Talker is a simple tool for typescript-style communication between 2 or more Cedar users. It is included in the automatic bringover and in the prerun line of the standard user.profile. Talker registers a "Talk" command with the UserExec. Tank ------------------ DF file: Tank.df Documentation: Click "Help" in tank viewer's menu. Implementor: Maxwell New Entry. TerminalMultiplex ------------------ DF file: TerminalMultiplex.df Documentation: See comments in TerminalMultiplex.mesa Implementor: Levin Unchanged. Tioga ------------------ DF file: Tioga.df Documentation: TiogaDoc.Tioga and TiogaDoc.press Implementor: TiogaImplementors^ Changes are mostly bug fixes and performance tuning. TIP ------------------ DF file: TIP.df Documentation: [Indigo]Documentation>TIP.documentation and TIP.syntax Implementor: McGregor Recompilation only. TSetter ------ DF file: TSetter.df Documentation: TSetterDoc.Tioga, [Indigo]TSetter>TSViewer.mesa Implementor: Plass A couple of user interface changes: the viewer no longer hides any of its buttons, and the Copies field is reset to 1 when the tool goes idle instead of at the end of each file. TTY, ViewerIO ------------------ DF file: TTYIO.df Documentation: see comments in ViewerIO.mesa Implementor: Warren Teitelman New procedure, CreateMessageWindowStream, which creates a stream that dumps characters to the message window whenever a flush is performed. UECP ----- DF file: UECP.df Documentation: None Implementor: Gifford, Stewart Unchanged. Unique ------- DF file: Unique.Df Documentation: Unique.Doc Implementor: Schmidt Recompilation only. UserCredentials -------------- DF file: UserCredentials.df Documentation: See comments in UserCredentials.mesa Implementor: Levin There is a new LoginOption, "alwaysPrompt", that forces Login to ask the user to login. See details in the interface. UserExec -------- DF file: UserExec.Df Documentation: [Indigo]Documentation>UserExec.tioga for description of user interface, UserExec.mesa for description of program interface. Implementor: Warren Teitelman Many new features in user interface. Changes and new features to the program interface. See UserExec.changes accessible through UserExec.df UserProfile ------------------ DF file: UserProfile.df Documentation: See UserProfile.mesa or [Indigo]Manual>UserProfile.press, UserProfile.doc or [Indigo]Manual>UserProfile.doc.press Implementor: Warren Teitelman No changes to UserProfile.mesa. Various changes to UserProfile.doc corresponding to new profile entries for various packages, or entries that have been withdrawn. VersionMap ----------- DF file: VersionMap.df Documentation: VersionMap.mesa Implementor: Atkinson No change. VersionMapBuilder ------------------ DF file: VersionMapBuilder.df Documentation: See implementor. Implementor: Atkinson Numerous changes to support faster/better version map creation. The 'openr' and 'findr' commands are no longer supported by this package (they have been moved to BBV). Viewers ------------------ DF file: Viewers.df Documentation: ViewerDoc.tioga and ViewerDoc.press Implementor: McGregor Large numbers of bugs have been fixed. The ViewerEvents interface has been extended to include filters for particular Viewers as well as Viewer classes. A new interface, ViewerLocks, is exported to support client locking of the Viewer data structures for read and write operations. John Maxwell's Desktop features have replaced the old "Fly" facility. ViewRec ------------------ DF file: ViewRec.df Documentation: ViewRec.doc Implementor: Spreitzer The ability to invoke some functions with keystrokes has been added. Specifically, shifted and unshifted SPARE2 go to the previous and next fields, CR does the obvious thing, and CTRL-CR invokes the procedures whose argument has been edited. Facilities have been added for Clients to register their own ways of dealing with certain TYPEs or individual fields. VTables -------- DF file: VTables.df Documentation: VTables.mesa Implementor: Atkinson No change. Walnut ------- DF file: Walnut.df Documentation: HowToUseWalnut.tioga, .press Implementor: Willie-Sue Haugeland To get the documentation, do bringover /o /a HowToUseWalnut.tioga Walnut.df The internals of Walnut have been substantially simplified. The database schema has been changed; if you attempt to use a database constructed with the previous schema, Walnut will inform you that you must scavenge. There are unbound imports in this version of Walnut (these have to do with talking to Alpine; do not worry). WalnutSend no longer has its own df file; instead, get it from: bringover /o /a WalnutSend.bcd Walnut.df The first time WalnutSend is run, it will get its icon file from Walnut>. BEFORE converting from Cedar 3.5.2 to Cedar 4.0, you need to: Rename Walnut.DBLog _ DB.walnutlog -- name of walnut's log file has changed Make sure you save Walnut.DBLog before erasing your disk!! Major changes (see the documentation for full details): DBText mode for displaying messages has disappeared. The Walnut control window icon raises its flag when there is new mail; there is a button in the Active message set displayer for retrieving new mail. WalnutSenders always display a new form after delivery, and save the last successfully sent message, which is recovered by clicking PrevMsg. Blue-clicking Send will destroy the sender after delivery. Senders have their own icon. While a send is in progress, the caption on the sender changes to "Sending...". The menu items for MsgSet displayers have changed. Bugs/Non-Features: If you have typed Walnut, and it does the automatic scavenge to rebuild its database, the icons do not get set up properly; you'll get acorns instead. Subsequent calls of Walnut will have the correct icons. During this automatic scavenge, do not display any message sets; wait until Walnut 4.0.1 is printed in the control window. Watch ------ DF file: Watch.df Documentation: none Implementor: Andrew Birrell Watch now gives more details on VM usage. To see them, use Red-Shift on the Sample button. The defaults for GC interval and the sample interval have been changed (to 16000 words and 2 seconds). Waterlily --------- DF file: Waterlily.df Documentation: via the "?" facility in the UserExec. Implementor: Kolling The identifying number pair at the start of each line in the difference file is now file number/position number instead of file number/line number. Some minor changes have been made to the non-default behavior to make compares of many files easier (see the /o and /p switches documentation). WorldVM --------- DF file: WorldVM.df Documentation: None - consult implementor before using Implementor: Andrew Birrell Minor bug fixes Unless otherwise indicated above, questions about changes in individual components should be addressed to their implementors. The Release Master
