Tandem Port of Info ZIP (zip)
|
|
=======================
|
|
|
|
History:
|
|
1. Tidy up COMMACS/MACROS/MAKE
|
|
2. Changes for version 5.32d affected files:
|
|
- TANDEMC (changes to stat() for UNZIP)
|
|
- ZIPUPC (changes to use REVISIOH rather than REVISEH)
|
|
- ZIPFILEC (don't add ".zip" to ZIP name)
|
|
- FILEIOC (cosmetic missing "*/")
|
|
3. Fix to allow zipping of files called ZIP (e.g. DAVES.ZIP)
|
|
03/08/98 2.3e Process Tandem DEFINE names - use define name as internal name
|
|
Remove BITSO from build of ZIPLIB
|
|
New DOIT macro for extracting files from archive
|
|
17/08/98 2.3e Set USE_EF_UT_TIME to allow for timezone changes
|
|
18/08/98 2.3e Use define LICENSED to build object able to update timestamps
|
|
30/11/98 2.3h Updated mapname/chmod/in2ex, include licensing in MAKE
|
|
21/12/98 2.3i Add simple Enscribe file handling, consisting of:
|
|
- storing Enscribe files as LF delimited text files
|
|
- adding Tandem Extra Field, holding Enscribe file attributes
|
|
Create ZIP file with Tandem File Code 1001
|
|
Rationalised TANDEMH and TANDEMC wth UNZIP 5.40d
|
|
12/01/99 2.3i Correct bug stopping setting of last open timestamp
|
|
25/01/99 2.3k Add '-B' flag to zip Enscribe files with no record delimiters
|
|
26/01/99 2.3k Make CRLF the default delimiter for Structured and Text files
|
|
01/02/99 2.3k Use maximum size large transfer read (57344) as default, allow
|
|
smaller value as option
|
|
01/02/99 2.3k Redefine -B flag for Edit/Enscribe files as in table below.
|
|
Default (-B or -B0 or no flag) is add CR/LF
|
|
|
|
-B<number> options at present are:
|
|
Bit 0 - Don't add delimiter (Edit/Enscribe)
|
|
Bit 1 - Use LF rather than CR/LF as delimiter (Edit/Enscribe)
|
|
Bit 2 - Space fill record to max record length (Enscribe)
|
|
Bit 3 - Trim trailing space (Edit/Enscribe)
|
|
|
|
Bit 8 - Force 30K (Expand) large read for Unstructured files
|
|
|
|
06/02/99 2.3k Attempt to catch Large Transfer mode failure (err 21) when
|
|
attempting 56K reads, add substitute 30K reads (Expand files)
|
|
24/03/99 2.3m Split TANDEMC into TANDEMC/TANZIPC/TANUNZC
|
|
24/03/99 2.3m Added TANNSKH to allow for declarations which require
|
|
structures defined in ZIPH after call to TANDEMH
|
|
11/05/99 2.3m Change zopen in TANZIPC to allow opening of files with
|
|
missing alt keys (err 4)
|
|
Assume not DST if can't resolve time (no DST table available)
|
|
27/09/99 2.3o Fixed bug in -B0 option causing files to be stored rather than
|
|
deflated. Created TANZIPH
|
|
29/04/02 2.4g Fixed contention on temporary file when multiple ZIPs run
|
|
|
|
A few notes about the files on this subvol
|
|
|
|
COMMACS - used by MAKE (compiler)
|
|
DOIT - macro to extract required Tandem files from archive and rename
|
|
MACROS - used by MAKE (bind)
|
|
MAKE - recompile ZIP code, attempts to only recompile changed code
|
|
README - this file
|
|
ZIPLIB - library of ZIP compiled routines, used by ZIP/ZIPNOTE etc
|
|
ZIPL - ZIP object (bound using LARGE memory model)
|
|
ZIPNOTE - ZIPNOTE 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 ZIP object onto Tandem
|
|
- download Tandem Zip executables archive from Web
|
|
- using PC unzip program (e.g. pkunzip/WinZip) extract ZIP
|
|
- copy ZIP 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) compile source code (requires UNZIP on Tandem)
|
|
- download ZIP source archive fwom 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
|
|
- NOTE that revision.h must be restored as REVISIOH
|
|
- 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 the zip file
|
|
(-o option) you need to add the line "#define LICENSED" to the TANDEMH file.
|
|
If you set this option then 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 ZIP the define is setup (default) in tandem.h
