05-10-1994 Mr Ni! (the Great)
9.92 rev. 2.024 (Release)
* Bug removed from ARJ_BETA code. Files that can't be packed are now
stored correctly
* Unarj Junior versions bit smaller and faster code
18/09/1994 Mr Ni! (the Great)
9.92 rev. 2.023 (Release)
* Mode 4 packing 3 to 5 times faster :-) Packing speed is roughly
the same as LZH 3.xx. Pack ratio is less. Expected future speed
improvements are:
-usage of Chaos CRC-routines (30% faster as the currently
used routine)
-conversion to assembly of the whole pack routine (now only the
dictionary search and update is optimized)
-usage of the UNARJ file buffering routines
-usage of again another tree structure????
Expected speed reductions are:
-mode 1 packing (bigger sliding dictionary, huffman tree building)
-support of all ARJ commands and some TOS-crew additions (to be
recognized with -~)
* Added wildcards to ARJ_BETA, not the sophisticated I_A wildcards
but standard OS controlled wildcards (user request from
Chipswinger). For recursive packing of subdirectories please
wait for the user interface by Insh_Allah.
* Removed file load bug from ARJ_BETA, modulo 32678 files don't
result in an error message anymore
* Changed IRA support to terrorists support: as long as the treaty
in Northern Ireland holds IRA support is removed. We are looking
for another terrorist organisation to be supported by -~b ;-)
* even smaller depack routines to include into your own programs:
mode 1-3 depack: 1012 bytes
mode 4 depack: 144 bytes
mode 0 depack: trivial
Use UNARJ_PR to dump packed data in a file, see for usage of
-~d the documentation of UNARJ_PR
* Added the TOS-crew ARJ icons (for use with TeraDesk, I've heard
that the normal Atari desktop won't work with icons bigger
than 32x32. Well, these icons are bigger, so get TeraDesk 1.40A
(that's the newest version now (about 5 days old now))
* the TOS-crew now can be contacted by e-mail! Write to:
i_a@mbh.wlink.nl to contact Insh_Allah or
mr_ni@mbh.wlink.nl to contact me (Mr Ni! (the Great))
* for easy use of ARJ_BETA install the program on your desktop
(TeraDesk is the best)(use menu item 'install application')
and enter at the command line:
d:\result.arj %f
Now you can drop the file(s) to be packed on the ARJ_BETA icon
and the files will be packed in the file d:\result.arj.
If the file result.arj already existed the file will be deleted
destroying all previously packed files and a new file will be
created.
rev 2.018 - 2.022 internal development revisions
* tried to improve packing speed by using the following tree
structures:
-simple sorted list with insertion sort updating (far to slow)
(don't say I should have used quicksort, each byte has to be
inserted in a sorted list followed by a tree search. Trying to
quicksort a sorted list is deadly, in this case insertion sort
is really the fastest (and of order n))
-linked trie structure (memory efficient but slow)
-sequential trie structure (please insert 8MB)
-own developed statistical dictionary search (best yet)
30/08/1994 Mr Ni! (the Great)
rev. 2.017 (Release)
* Even faster decrunching in UNARJ and UNARJ_PR
* Bug in dump-mode fixed (UNARJ_PR)
* Added depack and CRC sources, free to include in your programs
* Smaller Junior versions
* ARJBETA included, I am still working on it but here is a first
sample of things to come. Next version will be faster (I hope)
and will include a userinterface by Insh_Allah (he coded the
user interface of all the UNARJ versions too!)
rev 2.004 - 2.016 (Internal ARJ development versions)
04/07/1994 Mr Ni! (the Great)
rev. 2.003 (Release)
* Fixed bug in environment handling, all works now as promised (I do
hope so).
* Further optimized CRC and depack routines.
* Changed to a new, faster, printf routine, converted some string
routines to assembley.
* Total speed improvement compared to previous release about 2%.
??/05/1994
rev. 2.002 (internal revision)
* Fixed bug in decode routine, very rare arj files could trigger
this bug; one of the over 10000 files (over 1GB packed data) we
tested trigered this bug.
05/04/1994
rev. 2.001 (internal revision)
* Fixed bug in short usage.
06/03/1994 Insh_Allah
rev. 2.000 (release)
* Changed to version 9.90β: prelude to ARJ (which will start at version
10.00)
We chose rev 2.000 as the documentation talks about rev. 1.0xx and
upwards. We didn't want to change that so we updated the 'revision'
number too!
* filecount display bug removed
* problem with startup-code from Pure C/Turbo C removed: all filenames
(including the ones containing characters > ASCII 127) are recognized
correctly now. (Pure C startup-code treated commandline input as array
of 'signed char' and compared (*p <= ' ') to cut commandline into
argv[] list!
* most texts have been changed to German for UNARJJRG.TTP (some
error-messages are still in English though!)
* UNARJ Junior versions now can 'test' archives as was listed in the
documentation long ago. (The first Junior Versions were targeted NOT to
be able to TEST, only to VIEW and EXTRACT!)
* Configuration-structs have changed, which results in over 32 KILOBYTE
less DATA-space in de executable on disk!
* repaired 'broken archive' handling which seemed to be broken long time
ago.
* removed pointer-related bug in short-usage()
* removed bug related to newly introduced dump-mode and 'UPDATE/FRESHEN'
setting: warning was issued for every (UN)ARJ version, even the ones
that don't carry the dumpmode along...
30/01/1994 rev. 1.101 (Internal Revision) alpha
* commandline parser bug (SERIOUS ONE!) removed: previous versions
COULDN'T handle the promissed option-concatenation as far as constructs
like
-auvjr1jx
which is meant to be decoded as
-a -u -v -jr1 -x
were concerned: switching back to 'normal' (read as: 'non-shifted')
options would force an errormessage due to some bug in the parser-code.
Oops!
Well, to be honest is went something like this: I adapted the option-
lists without changing the parser-code accordingly, so it went a teeny
wheeny bit wrong at this particular point. Now that I didn't get any
furious user on the phone about this one means:
1) users didn't yet concatenate options that fanatically, or
2) users didn't think it was worth the paper their anger would be
spilled on, or
3) otherwise, in fact ...............................
(*) mark the number of your choice and, where required, please do write
something on the dotted lines... ;-]
* Now we are 100%% ARJ compatible as far as commandline parsing is
concerned as we can mix various shifted options (see the on-line
manual, to be shown when executing
(UN)ARJ -?
for details)
* We decreased usage information when an error occurs, so users can still
read the line(s) listing the error, even if they have option '-jp'
switched off. The usage() can be viewed using '-? -jp' anyway!
* 'presumes_curdir': bug fixed which caused routines NEVER to find
trailing '\\' when it DID exist at the end!
06/01/1994 21:29 rev. 1.092 (Internal Revision) alpha
* bug with CRC calculus for 1-byte, 2-byte, 64KByte+1 byte, 64KByte +
2-bytes, etc... filelengths. Run that test properly now (When intro-
ducing Chaos CRC routine, we did change some things to fit the routine
into the rest of the code, but we unfortunately DIDN'T check these
special filesizes. (oops 8-[ )
* bug when displaying introductionary usage() fixed: when that text was
displayed, settings would be such that it would allways be printed as
i
