Release Notes 10 January 1993
----------------------------
Version 1.6
HyperWais Stack
---------------
- The document type is now sent when adding to
relevance feedback. This was done to support the FTP
extensions in the WAIS server implemented by UNC.
- Added support for MBIN (MacBinary type documents),
the stack will prompt the user for a name to save under
and will then proceed to unbinify the document. The document
will be saved whether the user selects "view" or "save" from
the document menu. Currently there are no sources that I
know of which will provide documents in MacBinary
format, but this would be useful to someone who wanted to
provide an archive of Mac applications for people to search
and download applications from.
- Added support to allow users to define which applications
they want to launch when retrieving a particular document type.
This is done through the "Edit Applications" card, the user needs to
fill in the wais document type, the file type (a default of '????"
is used if no file type is specified), an application (which
is selected by using either the "select application" button or
clinking in the application field) and clicking on the MacBinary
box to indicate whether the user wants to convert the document
from a macbinary format (as far as I know only one wais server
serves documents in a macbinary format, that being the sample
-pictures server). When the user has finished entering the
information, "save" can be pressed to add the entry to the table.
If the document type is already handled by the stack (such as
TEXT, WSRC, WCAT and PICT),v the user will be asked whether they
want to override the built-in handler or use the selected application.
If the user chooses to override the built in handler, then the
application will be used to view a document and the file type
will be used when saving a document. The handler which uses an
external application to view the document will prompt the user
for a file name for saving the document before displaying it.
This facility allows the user to choose which applications to
use to display documents and also allows the internal handlers
to be over-ridden. This allows HyperWais to retrieve and display
any document type provided there is an application to view it
with. Currently the format of the table is not really very pretty
and could be cleaned up considerably.
A couple of things I should mention here, some applications do
not like to be opened with a document when they are already
open (they beep at you) while other are better behaved and will
allow that. I have found that GIFConverter does not behave well
whereas JPEGView does, but I may well have an older view of
GIFConverter. You will have to experiment for yourselves here
with your favorite applications.
- Added support for easier selection of sources when adding
them to the source list. A dialog box will appear listing all the
sources in the wais-sources folder. This dialog box allows
the user to select any number of sources using the shift-key
to select ranges or the option key to select any source and
then pressing the "Add" button to add all the selected
sources to the source list. Note that the wais source files
have to be of type TEXT or WSRC.
- Fixed a number of bugs in the background script which
handles adding of sources to the source list.
XFCNs
-----
- The document type is now sent when adding to
relevance feedback. This was done to support the FTP
extensions in the WAIS server implemented by UNC.
- Added an XFCN (HCConvertFile) which will convert
a text file from unix/dos format to mac format. Only
the data fork of the file is converted.
The syntax for this XFCN is:
put HCConvertFile(fileName) into error
fileName can be gotten using "answer file".
- Converted all XCMD projects to use 4 byte integers.
Wais Caller routines
------------------
- The document type is now sent when adding to
relevance feedback. This was done to support the FTP
extensions in the WAIS server implemented by UNC.
- Converted all projects to use 4 byte integers.
Wais Listener and C Libraries
--------------------------
- The document type is now sent when adding to
relevance feedback. This was done to support the FTP
extensions in the WAIS server implemented by UNC.
If not document type is specified, the Listener takes th e
default document from the document type list for that
document.
- Fixed a bug which did not truncate a file when it was
opened for over-writting, this resulted in garbled files
when saving a document to a file which already existed,
contained stuff in it and was longer than the document saved.
- Fixed a bug which did not append a carriage return at the
end of the first document type when multiple document types
were returned, this caused the first and second document
types to be merged into one string of characters.
- Fixed a bug in the memory management routines which caused the
Wais Listener to quit with a bus error on a Quadra 950 running 7.0.1.
The bug was caused by disposing a invalid handle.
- Converted all projects to use 4 byte integers.
- The log file is not not created for the "Wais Listener". The
"Wais Listener.debug" now list all debug information in the
window.
