- The stack is now autoconfiguring making installation easier, the stack looks for the wais-sources folder in the folder where it is located.
- The handling of downloading is a little easier, clicking on a headline will display the document/picture/source while holding down the option key and clicking on a headline will prompt the user for a name and save the document under that name. Option clicking on a source file headline will automatically download the source file and add the source name to the source scroll box.
- The headlines are now transfered as a block from the wais listener to the hypercard stack making for a faster display of results. Unfortunately only the document score and headline are transfered at this time. This is a limitation of the XFCN that implements this.
- Diagsnostic records returned from the wais servers accessed are now displayed when returned.
- Error processing and recovery has been greatly improved.
- The HCOpenConnection XFCN now pops up a dialog window if it cannot connect up to a wais listener on the machine it is running on. This allows the stack to connect up to a wais listener application running on another machine.
Wais Listener and C library:
- The wais listener now supports the concept of a connection. This means that it can now manage (up to 10) connections from clients which may be on the local machine or another machine. Note that by default the wais listener is set up memory wise to manage four connections. More memory will need to be allocated (using the get info dialog) if you need to run more than four connections. The recomended allocation is about 100K per connection. Of course if you only need one connection, the wais listener will run with less memory, though the minimum is set at 300K. In the future memory management will be improved and made more dynamic.
- The wais listener now returns diagnostic records from the wais servers it accesses, diagnostics are now returned when searches are made and when documents are downloaded. The only diagnostic that is masked in the D_PresentRequestOutOfRange. This occurs when a client asks for a document chunk that is past the end of the document. The glue code takes care of handling this.
- Downloading documents are now no longer limited to the document length or number of lines returned by the server. This number only serves as an indication of the length of the document and when downloading a document, the wais listener will just download until the wais server indicates that the request is out of range, ie when the real end of the document is reached.
- The wais listener now supports the transfer of a range of result headlines as well as single result headlines. This was done to improved performance when transfering data from one application to another using apple events.
- A couple of minor bugs were fixed in the clearing of various arrays, though this did not create any problems.
- The error numbers have been cleaned up and reorganised.
