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.
