Tandem Port of Info ZIP (unzip)
=======================
Recent changes:
1. Support UNZIPing of EDIT (text) files by use of the "-a" parameter
2. Changes for version 2.2 affected files:
- TANDEMC (changes to stat() to pass file creation time)
- ZIPINFOC (exclude TANDEM from tzset() test)
3. Fix to default time/date field to UK format (dd/mm/yyyy)
03/08/98 5.33f Updates for TANDEMC/H to keep instep with ZIP (file buffering)
New DOIT macro for extracting files from archive
Fix in2ex to expand full vol/subvol depending on '-j' flag
17/08/98 5.33f Set USE_EF_UT_TIME to allow for timezone changes
18/08/98 5.33f Use define LICENSED to build object able to update timestamps
19/08/98 5.33f Add -X flag support (restore file owner id) via unzip.c/h
new chown function in tandem.c.
Modified close_outfile to make the chown the last step.
30/11/98 5.41a Updated mapname/chmod/in2ex, include licensing in MAKE
21/12/98 5.41a Add decoding of new Tandem extra field EF_TANDEM
Make '-a' default option. Add '-b' option to force creation
of 'C' filecode 180 type text files.
If available populate Tandem file code (e.g. Object files)
Rationalised TANDEMH and TANDEMC wth ZIP 2.3i
Fixed MORE (-M flag) processing by creating zgetch()
12/01/99 5.41a Correct bug stopping setting of last open timestamp
24/03/99 5.41b Split TANDEMC into TANDEMC/TANZIPC/TANUNZC
24/03/99 5.41b Added TANNSKH to allow for declarations which require
structures defined in ZIPH after call to TANDEMH
07/05/99 5.41c Assume not DST if can't resolve time (no DST table available)
01/06/99 5.41c Add steps to make Self Extracting files (SFX)
12/01/01 5.42g Fix problems with MAKE for WIDE objects, updated TANDEMC/H
in line with ZIP, updated DOIT to remove TIMEZONE.C
If we ever want to use TIMEZONE.C then we need to set the
define IZTZ_DEFINESTDGLOBALS, it then compiles OK. The object
would need to be added to the building of UNZIPLIB in make.
09/02/01 5.50a Added code to tandem.c to create files with appropriate
extent sizes, or actual values if file was originally NSK
15/02/01 Update tandem.c to force first character to 'A' for Tandem
filenames
12/04/01 5.50c Fix problem with duff EF lengths in ef_scan_for_tandem
12/04/01 Change definition of nsk_attrs to allow for Wide mode and
subsequent respecifications of procedures that use it
12/04/01 Fix bug in tanunz.c so that call to FILE_ALTERLIST_ has upper
case filename
12/04/01 Update tandem.c to only allow '$' in in2ex as appropriate
16/07/01 5.50g Fixed bug in tandem.c for incorrect use of slist_items rather
than vlist_items
18/07/01 Allow edit files to be created with original extents
25/07/02 5.51b Add "-r" remove file extensions command line option
07/08/02 5.51b Non-Tandem non-text files now set to code 0 (not 100)
21/10/02 5.51b Tandem Enscribe files containing text set to code 101
03/01/03 5.51b Fix bug in extract of Text files - caused by Deflate64 changes
which made various buffers 64k and mismatches with unsigned.
Added NO_DEFLATE64 to MAKE and made this the default for
non-WIDE mode. If DEFLATE64 is used and non-WIDE then it drops
down to MED_MEM model for OUTBUFSIZ logic.
A few notes about the files on this subvol
COMMACS - required by MAKE, *** held on ZIP subvol ***
DOIT - macro to extract required Tandem files from archive and rename
MACROS - required by MAKE, *** held on ZIP subvol ***
MAKE - recompile UNZIP code, attempts to only recompile changed code
MAKESFX - make SFX header file
README - this file
UNZIPLIB - library of ZIP compiled routines, used by ZIP/ZIPNOTE etc
UNZIPL - ZIP object (bound using LARGE memory model)
*C - Source file
*H - Header files
*O - Individual object files (when compiled by MAKE)
Install Notes:
==============
Stage 1 - get UNZIP object onto Tandem
- download Tandem Unzip executables archive from Web
- using PC unzip program (e.g. pkunzip/WinZip) extract UNZIP
- copy UNZIP from PC to Tandem in Binary mode s(FTP/IXF)
- alter file code to 100
- optionally place in $SYSTEM.SYSTEM to allow easy access from command line
Stage 2 - (optional) retrieve source code (requires UNZIP on Tandem)
- download UNZIP source archive from web - contains all supported platforms
- copy archive onto Tandem as Binary
- extract Tandem DOIT macro ( UNZIP -j <archive> tandem/DOIT )
- update DOIT macro to point at archive file
- restore relevant files by running DOIT
- replace references to $T with a collector on your system
- replace references to SUPER.DAVES with whatever user id you use
- to compile run MAKE (compiles, accelerates, licences)
- NOTE: Always run the accelerated object on TNS/R systems, otherwise
it runs extremely slow.
Additional Notes - LICENSE the object:
======================================
If you wish to be able to update the last modified time of files you unzip
you need to add the line "#define LICENSED" to the TANDEMH file. If you set
this option you MUST FUP LICENSE the file as SUPER.SUPER.
This is a Tandem restriction since we have to call a PRIV procedure to update
the file label. For UNZIP the define is setup (default) in tandem.h
Additional Notes - Self Extracting
==================================
To create a Self Extracting (SFX) file you need to do the following
- run the MAKESFX file to create the SFX object files
- create a normal Zip file
- create an empty Unstructured file
- FUP COPY SFX into new file
- FUP COPY your Zip file to the end of this new file
- run ZIP -A <zipfile> to fix the internal pointers
- alter the filecode of <zipfile> to 100 (I'll do this in Zip -A soon)
For performance you should Axcel the finished file.
