- 26 August 1995 - Hans Wessels
- 9.96 rev. 3.008 (release)
- GENERAL
- * New e-mail adresses:
- Hans Wessels (that's me!): MR_NI@MST.TN.UTWENTE.NL
- or: MR_NI@MBH.ORG
- Ger Hobbelt (Insh_Allah) : I_A@MBH.ORG
-
- ARJBETA
- * Improved sliding dictionay code, it is quite fast now! No problem
- with Degas pictures anymore.
- * Added mode 7, a compression method incompatible with ARJ from Mr
- R. Jung, but better compression, especially on test files. This
- mode uses a 32k dictionary instead of a 26k dictionary.
- * Added mode 1-7 support, added -jm support:
- -m7 -jm : best compression, incompatible with ARJ from Mr R. Jung
- -m7 : good compression, incompatible with ARJ from Mr R. Jung
- -m1 -jm : best compression, compatible with ARJ from Mr R. Jung
- -m1 : good compression, compatible with ARJ
- -m6 -jm : lesser, but faster compression, incompatible
- -m6 : lesser, but faster compression, incompatible
- -m2 -jm : lesser, but faster compression, compatible
- -m2 : lesser, but faster compression, ARJ Jung compression ratio
- -m5 -jm : medium, but fast compression, incompatible
- -m5 : medium, but fast compression, incompatible
- -m3 -jm : medium, but fast compression, compatible
- -m3 : medium, but fast compression, LZH compression ratio
- -m4 -jm : low, but fast compression, compatible
- -m4 : low, but fast compression, compatible
- -m0 : no compression, store files, compatible
-
- UNARJ:
- * Unarj is prepared for mode 8, an improved mode 1 packing algorithm
- with a bigger sliding dictionary (64k). This mode 8 is incompatible
- with the original ARJ by R. Jung.
- * Unarj is compatible with ARJZ, a Russian ARJ packer using a 64k
- sliding dictionary.
-
- 3 Juni 1995 - Hans Wessels
- 9.95 rev. 3.007 (internal revision)
- ARJBETA:
- * New sliding dictionary code, faster on textfiles, still slow on
- Degas picture files.
-
- UNARJ:
- * Unarj is prepared for mode 7, an improved mode 1 packing algorithm
- with a bigger sliding dictionary (32k). This mode 7 is incompatible
- with the original ARJ by R. Jung.
-
- 7 May 1995 - Hans Wessels
- 9.95 rev. 3.006 (internal revision)
- ARJBETA:
- * Improved packing algorithm a little bit, slightly better compression.
- * -v without a number: use free diskspace as volume size.
-
- 23 April 1995 - Hans Wessels
- 9.95 rev. 3.005 (internal revision)
- ARJBETA:
- * Implemented new Huffman calculation routines, 20 times faster as
- the original routines! Overall speed improvement: c.a. 10%.
-
- 12 March 1995 - Hans Wessels
- 9.95 rev. 3.004 (release)
- ARJBETA:
- * Improved packing ratio. ARJBETA has proven to pack better than:
- -LHArc 3.10 on the ST 230KB better on 27.5MB
- -STZIP 2.5 on the ST 134KB better on 27.5MB
- -ARJ 2.41a on MS DOS using -jm 195KB better on 152MB
- -PKZIP on MS DOS 159KB better on 152MB
- * fixed bug in sliding dictionary code
- GENERAL:
- * added the ARJBETA.FAQ file: the answers to frequently asked questions.
-
- 9.94 rev. 3.003 (internal revision)
- ARJBETA:
- * Fixed dictionary length, the sliding dictionary was 1 byte too long,
- causing an incompatibility with ARJ on MS DOS (not with UNARJ ST).
- * Multiple volume support. You can use the switch -v<number> to enable
- packing in multiple volume archives. The number has the following
- meaning:
- -v180 volume size is 177152 bytes (single sided 40 x 9 disk)
- -v200 volume size is 197632 bytes (single sided 40 x 10 disk)
- -v205 volume size is 202752 bytes (single sided 42 x 10 disk)
- -v360 volume size is 360448 bytes (single sided 80 x 9 or
- dual sided 40 x 9 disk)
- -v400 volume size is 401408 bytes (single sided 80 x 10 or
- dual sided 40 x 10 disk)
- -v405 volume size is 406528 bytes (single sided 82 x 10 disk)
- -v410 volume size is 411648 bytes (dual sided 42 x 10 disk)
- -v720 volume size is 728064 bytes (dual sided 80 x 9 disk)
- -v800 volume size is 809984 bytes (dual sided 80 x 10 disk)
- -v820 volume size is 830464 bytes (dual sided 82 x 10 disk)
- -v1440 volume size is 1456640 bytes (dual side 80 x 18 (hd)disk)
- -v1600 volume size is 1623040 bytes (dual sided 80 x 20 (hd)disk)
- -v1620 volume size is 1664000 bytes (dual sided 82 x 20 (hd)disk)
- -v2880 volume size is 2913280 bytes (dual sided 80 x 36 (ed)disk)
- -v3200 volume size is 3246080 bytes (dual sided 80 x 40 (ed)disk)
- -v3240 volume size is 3328000 bytes (dual sided 82 x 40 (ed)disk)
-
- -v<(number > 8192)> volume size is specified <number> of bytes
- -v<all other cases> volume size is 1456640 bytes
- (dual side 80 x 18 (hd)disk)
- UNARJ:
- * Fixed some default options, most important, the default for -~g is now off,
- when switched on -~g extracts the file <filename>.ARJ in the folder
- <filename>.
- * Fixed bug in multiple volume handling: split volumes without a split
- file on the volume break are recognized too.
-
- 18-01-1995 Hans Wessels
- 9.94 rev. 3.002 (release)
- ARJBETA:
- * ARJBETA doesn't try to pack 2^32 bytes when it's only supposed to pack
- 1 byte.
-
- UNARJ:
- * Fixed some bugs in the e-command structures, causing the JR versions
- always to use the e command.
-
- 15-01-1995 Hans Wessels
- 9.94 rev. 3.001 (release)
- UNARJ_JR:
- * The e command now works in the UNARJ junior versions too!
-
- 9.94 rev. 3.000 (internal revision)
- General:
- * Switched from my alias (Mr Ni! (the Great)) to my real name:
- Hans Wessels. Hello everyone! My name is Hans Wessels, nice
- you read this document comming with my ARJBETA and UNARJ by
- the TOS-crew.
-
- New and improved in ARJBETA:
- * Mode 1 improved a lot! It's now better than the mode 1 of ARJ by
- R. Jung! Only the -jm switch of ARJ by R.J. might beat this ARJ
- implementation. ARJ is now the best packer on the ST platform!
-
- * Recursive file search implemented by Wout Klaren (many thanks Wout!).
-
- * File date, time and attributes are now stored too in the ARJ archive.
-
- * Implemented all ARJ modes but still no user interface, so you can
- only use the default mode 1.
-
- * Implemented the special cases, in theory (that means if there are
- no bugs in the program) all files are packed and depacked correctly.
- In the previous version the special cases weren't implemented, but
- files that trigger a special case are _VERY_ rare. (I didn't get any
- complaints of packing errors so I assume till now no one tried to
- pack such a special case file.)
-
- * Set file spec position in filename to the right value
-
- * Removed division by zero exception on empty files. (Has no visible
- effects on normal ST's with standard division by zero handler.)
-
- New and improved in UNARJ:
-
- * Fixed bug in commandline parsing, -jpxx now works correctly
-
- * Options e and -e are now working as they supposed to; extract archives
- without paths. (Bug reported by Albi Rebmann, thanks a lot for the bug
- report!)
-
- 30-10-1994 Mr Ni! (the Great)
- 9.93 rev. 2.030 (Release)
-
- * Mode 1 implemented, but there is still a lot of work to do on the
- algorithm
-
- * I have got a new e-mail address: mr_ni@mbh.org
- mr_ni@mst.tn.utwente.nl
-
- Insh_Allah's new address is: i_a@mbh.org
-
- * Most of the code was written at the SiliConvention in Delmenhorst.
- Hi Avena, Great party!
-
- rev. 2.025 - rev. 2.030 internal revisions
-
- 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.org to contact Insh_Allah or
- mr_ni@mbh.org 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
- if '-ss' option was enabled, even when it wasn't -> unreadable text
- flashing along on a single line, useless to the novice, for which the
- text is meant...
-
- 26/12/1993 ??:?? rev. 1.091 (Internal Revision) alpha
-
- * 'bugs' fixed concerning BACKUP flagged files: now (UN)ARJ listens to
- -jg and -jg1 switches correctly: -jg1 lists BACKUP files only with 'v'
- or 'l' commands; unless '-jg' or '-jg1' specified, you cannot extract
- any BACKUP flagged files (before, BACKUP flagged files were extracted,
- thus blocking their non-BACKUP flagged equivalents unless file
- overwrite was enabled. (boo :-((( ))
-
- * 'dump' mode introduced: very handy for those among you want to use
- ARJ-packed files for demo's or include it in their own source. 'dump'
- can be done in 'binary' or 'source' form; 'header-files' can be created
- on the way in Assembley or C-language. 'source'-dump can be either ASM
- or C-style.
-
- * once more ;-)) we reorganized our sources. BTW, we are now heading for
- the 100K executable. (unpacked!) Estimates are we can gain 40% with
- complete packed executable, but since I personally HATE ice! and other
- style packed executables...
-
- * included options (tested):
-
- -~ss (no screen scrolling) (user request)
-
- -~fb[nnn] specify amount of file-buffering. (handy in Multitasking
- Environments, negative values specify amount of mem still
- free when running (UN)ARJ)
-
- -~crc[n] CRC speed (and memory usage)
-
- -~* no CRC checking (unsafe but faster extracting)
-
- 12/12/1993 11:00 rev. 1.09 (Internal Revision) alpha
-
- * we keep 'alpha' in our version number as long as we don't have packing
- implemented...
-
- * depacking has been speeded up again (again!).
-
- * bugs removed concerning non-ARJ files:
-
- if you would do something like this
-
- UNARJ.TTP t -ray+ -v+ k:\*.*
-
- all files, including modules, texts, etc. are looked upon as possible
- ARJ files and, as you might have guessed, a lot of error-messages
- result from this action. However, we might expect to have the innocent
- user to issue such a command once in a while. (.ARJ extension is
- automatically added when you do this:
-
- UNARJ.TTP t -ray+ v+ k:\* )
-
- Things went WRONG ('Internal Error', crash(!), etc.) when you did this:
-
- UNARJ.TTP x -ray+ -v+ k:\*.*
-
- (really depack the shit you'll find) Now finally this problem has been
- fixed: UNARJ is made more butthead-proof...
-
- 22/09/1993 ??:?? rev. 1.03 alpha (intern)
-
- * Again speed up for mode 4 extracting.
-
- 09/09/1993 @ 00:44:?? rev. 1.02 alpha:
-
- * total files count fixes (was allways displayed as ZERO
-
- * total size etc. when viewing fixed.
-
- * redirection with stderr included ( >& ) fixed (we hope)
-
- * error-count report fixed: broken archives and unrecognized archives are
- counted as errors now too!
-
- added:
-
- * global error count report: summa summarum all errors.
-
- * even faster depacking still: speed increment by a marv' 10%
-
- 10/09/1993 @ 21:50:?? rev 1.03 alpha:
-
- * version 1.02 had a MAJOR BUG since we used new file-access routines:
- every ARJ was opened and immidiately WRITTEN to! No wonder every ARJ
- was bad afterwards and reduced to zero bytes in the process: how to get
- lots of free disk space (variant 3546 ;-(( )
-
-
