History (up to version 0.75)
-------
Modifications of the current version can be found in !Help.
0.50 (23 Jan 1991) - First release of !DiskBase. Running in Wimp but
individual actions not yet multitasking.
0.51 (02 Feb 1991) - Fixed a bug in DUPLICATES. Too many entries were
accused of being duplicates.
0.52 (13 Feb 1991) - Created fully multitasking actions. (ADD, DELETE,
SHOW, SEARCH, DUPLICATES)
0.53 (23 Feb 1991) - Results can be placed in a textfile on disk or copied
(via RAMtransmit) to another task e.g. printerdriver,
!Edit/!DTP etc.
0.54 (23 Mar 1991) - Some bugs fixed. (Nasty one in finding duplicates)
0.55 (04 Jun 1991) - Fixed some bugs in allocating memory, case-sensitivity
of diskname of Duplicates, closing datafile if loading
of it failed, and bugs in saving results file fixed.
Furthermore created sub-options in Duplicates for the
type of report.
0.56 (23 Jun 1991) - Added the option in SEARCH to include/exclude disks.
Also added the option to start files/applications or
open directories by double clicking on a line of the
RESULTS window.
0.57 (29 Aug 1991) - !DiskBase now only momentarily changes the CSD during
the addition of a disk directory but will restore it
before leaving this procedure.
Bug, resulting in a program crash when a SAVE failed,
fixed.
Added the Print DiskLabel option.
0.58 (14 Nov 1991) - Removed the resetting of the CSD added in version 0.57
because it could intermittently result in
"FileCore in use" errors. (Depending on DirCache-size
and/or Buffer-size of filing system).
- Created a multi-level menu-structure for fonts in
DiskLabel option, using FontMenu module designed by
Joris RÖling.
- Adding and deleting disks is now done from a window
(staying open) instead of from a submenu.
The contents of an archive file is now examined and
stored when adding a disk.
- DiskBase now also supports SCSI and IDE filing systems
so that harddisks with these filing systems can also
be stored. Due to the way information was stored in
the datafile I had to decide to store sizes of archive
files and directories in Kbytes (in 3 bytes, max size
16777 Mb) while applications sizes stay in bytes
(also in 3 bytes, so max application size is 16 Mb
bytes). Reason was that a maximum directory size of
16 Mbytes is far too less for harddisks.
Also filing system for each disk is now stored.
- Conversion of an older datafile when loaded in
!DiskBase 0.58 is done automatically. Consequence is
that when afterwards this updated file should be used
with an older version of !DiskBase, an incorrect size
of directories is shown. Also since the 0.58 version
knows a new entrytype for archive files added with
the 0.58 !DiskBase, these files won't be recognised
as files or archives when used afterwards with an
earlier release.
WARNING: Of course converting the datafile can't
automatically update the file with the contents of
the archive files, so you have to SEARCH yourself for
archive files (filetype &DDC) and then ADD all disks
containing archives to modify the datafile to contain
the contents of any archive files !!!!
0.59 (27 Dec 1991) - Main reason for this release was the fixing of some
bugs.
When deleting disks containing archives the number of
files wasn't decremented for deleted archives.
When an ADD of the contents of an archive file failed,
that disk wasn't added at all. Now changed into adding
the disk without adding the contents. In the ADD DISK
window is a choice for an optional warning if an ADD
of the contents of an archive fails.
Displaying file sizes in the RESULTS window is now
done using the SWI OS_ConvertFixedFileSize so that a
RISCOS consistent display is given.
When clicking on a line in the RESULTS window versions
below 0.59 called Wimp_StartTask also if it is a file
that should be run/started. This always causes a new
application being started, even if there is one copy
of that application already running. (e.g. clicking on
a TEXT-type file when !Edit is already running starts
another !Edit, instead of the running !Edit loading
the textfile).
Version 0.59 makes use of the Filer_Run syntax to
run/start a file, if RISCOS 3.0 is used !!!
This acts as double clicking on a file in a directory
viewer, so no other copy of an application is started
if it is not necessary. (e.g. the already running
!Edit will load the textfile).
In RISCOS 2.0 this facility is not available and the
other method is still used !!!
It is also possible to click not directly on a file
in the RESULT window, but on the directory the file
is in, and then double click on the icon in the
directory viewer.
0.60 (20 Jan 1992) - Added the summary option in SHOW. It gives a easier
to read overview of the contents of a disk.
- Now if RISCOS 2.0 is used !DiskBase uses the broadcast
Message_DataOpen to see if an application is already
running that is capable to load the selected file.
If not, that application is started by a *RUN of that
particular file. (See also the history of 0.59)
- Some (minor) speedup of the redrawing of the RESULTS
window by changing the code and by deleting the word
'bytes' when displaying entry sizes. (Even more RISCOS
compliant as well).
- Rectified several (grammatical) errors in this Readme
file. (Thanks to Kees Breet for his spelling checking)
0.61 (24 Feb 1992) - Size/filetype/timestamp of CFS-files shown now are the
ones of the uncompressed files. Previously files all
showed up with filetype of 'CFSlzw' and size/timestamp
of compressed file.
Already made provisions to show the difference of
archives made by !Spark and !ArcFS. !Spark archives
are shown with a 'S' and !ArcFS files with an 'A'.
At the moment all archives are shown as !Spark-files,
even if they are created by !ArcFS. In the latter case
how
