| 6725 | siemargl | 1 | Tandem Port of Info ZIP (unzip) |
| 2 | ======================= |
||
| 3 | |||
| 4 | Recent changes: |
||
| 5 | 1. Support UNZIPing of EDIT (text) files by use of the "-a" parameter |
||
| 6 | 2. Changes for version 2.2 affected files: |
||
| 7 | - TANDEMC (changes to stat() to pass file creation time) |
||
| 8 | - ZIPINFOC (exclude TANDEM from tzset() test) |
||
| 9 | 3. Fix to default time/date field to UK format (dd/mm/yyyy) |
||
| 10 | 03/08/98 5.33f Updates for TANDEMC/H to keep instep with ZIP (file buffering) |
||
| 11 | New DOIT macro for extracting files from archive |
||
| 12 | Fix in2ex to expand full vol/subvol depending on '-j' flag |
||
| 13 | 17/08/98 5.33f Set USE_EF_UT_TIME to allow for timezone changes |
||
| 14 | 18/08/98 5.33f Use define LICENSED to build object able to update timestamps |
||
| 15 | 19/08/98 5.33f Add -X flag support (restore file owner id) via unzip.c/h |
||
| 16 | new chown function in tandem.c. |
||
| 17 | Modified close_outfile to make the chown the last step. |
||
| 18 | 30/11/98 5.41a Updated mapname/chmod/in2ex, include licensing in MAKE |
||
| 19 | 21/12/98 5.41a Add decoding of new Tandem extra field EF_TANDEM |
||
| 20 | Make '-a' default option. Add '-b' option to force creation |
||
| 21 | of 'C' filecode 180 type text files. |
||
| 22 | If available populate Tandem file code (e.g. Object files) |
||
| 23 | Rationalised TANDEMH and TANDEMC wth ZIP 2.3i |
||
| 24 | Fixed MORE (-M flag) processing by creating zgetch() |
||
| 25 | 12/01/99 5.41a Correct bug stopping setting of last open timestamp |
||
| 26 | 24/03/99 5.41b Split TANDEMC into TANDEMC/TANZIPC/TANUNZC |
||
| 27 | 24/03/99 5.41b Added TANNSKH to allow for declarations which require |
||
| 28 | structures defined in ZIPH after call to TANDEMH |
||
| 29 | 07/05/99 5.41c Assume not DST if can't resolve time (no DST table available) |
||
| 30 | 01/06/99 5.41c Add steps to make Self Extracting files (SFX) |
||
| 31 | 12/01/01 5.42g Fix problems with MAKE for WIDE objects, updated TANDEMC/H |
||
| 32 | in line with ZIP, updated DOIT to remove TIMEZONE.C |
||
| 33 | |||
| 34 | If we ever want to use TIMEZONE.C then we need to set the |
||
| 35 | define IZTZ_DEFINESTDGLOBALS, it then compiles OK. The object |
||
| 36 | would need to be added to the building of UNZIPLIB in make. |
||
| 37 | |||
| 38 | 09/02/01 5.50a Added code to tandem.c to create files with appropriate |
||
| 39 | extent sizes, or actual values if file was originally NSK |
||
| 40 | 15/02/01 Update tandem.c to force first character to 'A' for Tandem |
||
| 41 | filenames |
||
| 42 | 12/04/01 5.50c Fix problem with duff EF lengths in ef_scan_for_tandem |
||
| 43 | 12/04/01 Change definition of nsk_attrs to allow for Wide mode and |
||
| 44 | subsequent respecifications of procedures that use it |
||
| 45 | 12/04/01 Fix bug in tanunz.c so that call to FILE_ALTERLIST_ has upper |
||
| 46 | case filename |
||
| 47 | 12/04/01 Update tandem.c to only allow '$' in in2ex as appropriate |
||
| 48 | 16/07/01 5.50g Fixed bug in tandem.c for incorrect use of slist_items rather |
||
| 49 | than vlist_items |
||
| 50 | 18/07/01 Allow edit files to be created with original extents |
||
| 51 | 25/07/02 5.51b Add "-r" remove file extensions command line option |
||
| 52 | 07/08/02 5.51b Non-Tandem non-text files now set to code 0 (not 100) |
||
| 53 | 21/10/02 5.51b Tandem Enscribe files containing text set to code 101 |
||
| 54 | 03/01/03 5.51b Fix bug in extract of Text files - caused by Deflate64 changes |
||
| 55 | which made various buffers 64k and mismatches with unsigned. |
||
| 56 | Added NO_DEFLATE64 to MAKE and made this the default for |
||
| 57 | non-WIDE mode. If DEFLATE64 is used and non-WIDE then it drops |
||
| 58 | down to MED_MEM model for OUTBUFSIZ logic. |
||
| 59 | |||
| 60 | A few notes about the files on this subvol |
||
| 61 | |||
| 62 | COMMACS - required by MAKE, *** held on ZIP subvol *** |
||
| 63 | DOIT - macro to extract required Tandem files from archive and rename |
||
| 64 | MACROS - required by MAKE, *** held on ZIP subvol *** |
||
| 65 | MAKE - recompile UNZIP code, attempts to only recompile changed code |
||
| 66 | MAKESFX - make SFX header file |
||
| 67 | README - this file |
||
| 68 | UNZIPLIB - library of ZIP compiled routines, used by ZIP/ZIPNOTE etc |
||
| 69 | UNZIPL - ZIP object (bound using LARGE memory model) |
||
| 70 | |||
| 71 | *C - Source file |
||
| 72 | *H - Header files |
||
| 73 | *O - Individual object files (when compiled by MAKE) |
||
| 74 | |||
| 75 | Install Notes: |
||
| 76 | ============== |
||
| 77 | Stage 1 - get UNZIP object onto Tandem |
||
| 78 | - download Tandem Unzip executables archive from Web |
||
| 79 | - using PC unzip program (e.g. pkunzip/WinZip) extract UNZIP |
||
| 80 | - copy UNZIP from PC to Tandem in Binary mode s(FTP/IXF) |
||
| 81 | - alter file code to 100 |
||
| 82 | - optionally place in $SYSTEM.SYSTEM to allow easy access from command line |
||
| 83 | |||
| 84 | Stage 2 - (optional) retrieve source code (requires UNZIP on Tandem) |
||
| 85 | - download UNZIP source archive from web - contains all supported platforms |
||
| 86 | - copy archive onto Tandem as Binary |
||
| 87 | - extract Tandem DOIT macro ( UNZIP -j |
||
| 88 | - update DOIT macro to point at archive file |
||
| 89 | - restore relevant files by running DOIT |
||
| 90 | - replace references to $T with a collector on your system |
||
| 91 | - replace references to SUPER.DAVES with whatever user id you use |
||
| 92 | - to compile run MAKE (compiles, accelerates, licences) |
||
| 93 | - NOTE: Always run the accelerated object on TNS/R systems, otherwise |
||
| 94 | it runs extremely slow. |
||
| 95 | |||
| 96 | |||
| 97 | Additional Notes - LICENSE the object: |
||
| 98 | ====================================== |
||
| 99 | If you wish to be able to update the last modified time of files you unzip |
||
| 100 | you need to add the line "#define LICENSED" to the TANDEMH file. If you set |
||
| 101 | this option you MUST FUP LICENSE the file as SUPER.SUPER. |
||
| 102 | This is a Tandem restriction since we have to call a PRIV procedure to update |
||
| 103 | the file label. For UNZIP the define is setup (default) in tandem.h |
||
| 104 | |||
| 105 | |||
| 106 | Additional Notes - Self Extracting |
||
| 107 | ================================== |
||
| 108 | |||
| 109 | To create a Self Extracting (SFX) file you need to do the following |
||
| 110 | - run the MAKESFX file to create the SFX object files |
||
| 111 | - create a normal Zip file |
||
| 112 | - create an empty Unstructured file |
||
| 113 | - FUP COPY SFX into new file |
||
| 114 | - FUP COPY your Zip file to the end of this new file |
||
| 115 | - run ZIP -A |
||
| 116 | - alter the filecode of |
||
| 117 | |||
| 118 | For performance you should Axcel the finished file. |
