1/6/97 Incorporate Castanet DIM under the common name putLocalPublisher. Updates to PDIF syntax to fix some grammar errors. Incorporate generic remote proxy capability (not fully tested). Changes to Executive to disallow more than one instance of a PIM or DIM to execute concurrently. A new option concurrencyLimit has been added to the exec but it should not be increased beyond 1 at the moment. Added remoteConnector and putToRemoteConnector for Proxy services. Removed their definition in Faceless at last minute due to bugs. Executive can now start the web service at any port. Previous bug had it wired to port 9090. A limit was placed on the size of the contents of the local debug window. If the contents exceeds about 20000 chars it gets chopped to 10000 by throwing away the old stuff. Product persistence now goes into a file that has the same root name as the saved checkpoint (ckpt) configuration file (but with extension .ps). On startup a search is made for a startup product persistence file with a root the matches the startup file. |

12/9/97 Email DIM check for a creator attribute to use for the "from" in the email header. If none found uses the juggler creator. Altavista and Excite PIM should now log any parse errors they may incur. Altavista rewritten to use the generic HTML parse routines in pkg ...getter.parse (smaller code, should be less sensitive to format changes from altavista) getter.parse pkg minor changes so an HTML tag with attributes can be parsed independent of the order of the attributes. Fixed output of PDIF for persistence of executive state and product state. THIS IS NOT BACKWARD COMPATIBLE. It simply requires that you delete the contents of the \0product_persistance directory before running this version for the first time. You must also start PAM afresh from the operating.txt file rather than a PAM generated chkpt.txt file. |
027 |
More minor interface changes and simplifications. |
026 |
11/18/97 Added ability to enable/disable modules from the built-in pam gui. Can also push a button to activate Jugglers or Daemons immediately (within a minute). Fixed minor bug in email PIM checking number of messages on pop server |
025 |
11/12/97 Executive now cleans up all unused files in the working directory when you shut it down from the GUI. Backweb proxy is no longer required! The new BackWeb DIM has a common name of putBackWebLocal |

10/20/97 - tech notes
11/6/97 - "Prior Users" PreRelease notes The following is a list of changes for PAM PreRelease 2.
|
022/23 |
10/7/97 Fixes to BackWeb proxy to deal with a few hardwired directories Creation of install notes for first "client" install Sucked in new Pointcast code, renamed as MbnDim (still not tested) |
0021 |
9/11/97 1604 Pointcast not properly keeping product files. URLs for FileRefs had spaces in them - fixed. Files as output of NotifyOfChange were not getting wrapped properly |
0020 |
9/8/97 16:06 Can serve BackWeb subscriptions from a web server peer. Fix PassThru bug with empy channels > 1 Fix BackWeb rendering problem with FileRef contents |
0019 |
9/4/97 19:52 BackWeb now properly supports multiple inputs. It also properly deletes temporary files. BackWeb renderer eliminates troublesome quote chars in text box. Start of new Daemon type. Begin implementation of downloadNumber |
0018 |
8/29/97 16:45 Many changes to pointcast and backweb presentation. PCN and Backweb use same renderer now. Split AsPCN... visitor to extract AsZip visitor Fixed bug in webcopy pim0 and webcopy pim1 Created new checkpoint juggler Exec now makes a checkpoint.old file and tries not to bash it if there is an error Exec understands debug parameters |
0017 |
8/26/97 16:43 PAM now creates log file to checkpoint directory. File grows without bound, however, during PAM operation. Gets erased when PAM restarts. Can now change description for jugglers by modifying ckpt file Several minor pointcast bugs & cosmetic fixes. PointcastDIM has a new attribute " pcnProtocolHostAndPort" that allows use of another "real" web server to serve out product if it has had PAMWorkingDir and PAMSupportDir aliases defined Many small BackwebDIM cosmetic changes. Notify of change Juggler new attributes "somethingChangedString" and "nothingChangedString" allows customization of reporting |
0016 |
8/21/97 07:44 Channel interface renamed to Juggler interface. Significant stability improvements to persistent storage (PDIFOutStream class) PointCast DIM should be fully operable EnumeratedProducts now can have index items and one root item. More Cosmetic updates to BackWeb Following files obsolete and deleted:
|
0015 |
8/18/97 16:02 Cosmetic updates to BackWeb Now have pointcast proxy source Entire system fully understands enabled and disabled items. PIMs, DIMs, or Channels that ask for sourcelist or sinklist get a list of only enabled sources and sinks. AsPlainText - cosmetic updates |
0014 |
8/15/97 16:45pm Pointcast DIM - new |
0013 |
8/13/97 15:40pm Exec - PIM product was not getting marked and garbage collected properly -fixed. DIM product now also marked and swept. BackWeb DIM - initial functions working, more work on cosmetics Now using JSDK 1.0.1 New Product approval Servlet and Channel (one of each). |
0012 |
8/6/97 11:24am DIM interface - removed entry point getCurrentFileRefs (use getPersistentProduct if needed) New DIM - PutDirectory |
0011 |
7/31/97 DIMs can now save persistent information Fixed DIM and PIM queue scheduling bug New aggregator to detect changes by date instead of content |
0010 |
7/29/97 BackWeb dim - initial version AcmeServer - numerous bug fixes for POST method mitre.pam.executive.PAM can now be invoked with a single command line arg which is the config/checkpoint file to use on startup. Checkpoints still go to default name in the 0checkpts directory. |
0009 |
7/25/97 16:37 ExecGlobal - bug fix to getUrlFromFile(File file) |
0008 |
7/24/96 15:03 ExecGlobal - new call - String getUrlFromFile(File file) |
0007 |
7/23/97 16:50 New BNN PIM New /PAMList servlet FileRef error fixed AsPlainText slight format fix ExecMonitor new API to get specific Source or Sink by ID - Used by Backweb subscribe servlet Mail classes - uudecode incoming enclosures |
0006 |
7/22/97 16:15 Added Alarm and debug classes. Added beginnings of a BackWeb Servlet for subscriptions to backweb channels. |
0005 |
7/23/97 7:23am Sink interface - Added an additional callback to Sink interface that allows the exec to notify a Sink when one of the sources has been disconnected. Default behavior of Channel and DIM base classes is to do nothing. Product persistence - rewrote product persistence mechanism to support an arbitrary "web" of products that reference each other (but not cyclicly). A single product persistence file is now used. ProductStore - moved to mitre.pam.product.view package as part of initial work to transition to JDK 1.1 serialization BasicProduct no longer supports content of Vector!!!! Use VectorProduct. Product.getContent() now returns Enumeration instead of Vector HashtableProduct - new, built for growth. BasicProduct - changed topic separator char to comma ","; new attribute, BasicProduct.TOPIC_SEPARATOR AsPlainText no longer appends date to id line MonitorFrame - no longer get exception when PIMQ or DIMQ are empty FileRef - can build unique name with specified prefix and extension |
0004 |
7/17, 1706 - Executive - understands how to schedule daily, hourly, and weekly BasicProduct can delete product attribute |
0003 |
7/16/97 1304 - Executive - pays attention to enable attribute on PIMs, DIMs, and Channels New PIM - pop mail get pim, only handles base64 coded enclosures New DIM - smtp mail put pim, only handles base64 coded enclosures |

PAM executive implements PIM,DIM,Channel persistence. PAM uses servlets that extend javax.servlet.httpServlet to get access to working directories, support directories, PAM exec state. Channel building is manual via bootstrap checkpoint file, Exec managment of checkpoint file still a little rough -- does not do checkpoint integrity checking before loading the file. Simple local GUI provides access to PIM, DIM, Channel. Also, to PIM, DIM, Channel queues. PIMs implemented include: 2 level web copy, altavista copy of up to 10 links, local directory look. Also local test pim. Channels implemented include: simple passthru from source to sink and channel to check if something changed DIMs include local test dim that echoes input to local window In the beginning there was Java... and it was good because it really enhanced software productivity. |
