- ================================
- For UnZip 6.0/6.1/who knows:
- ================================
- o add multi-part zipfile handling
- top of the list for 6.0!
- o add new low-level, binary API; rewrite "normal" (command-line) UnZip
- to use it
- very soon (maybe 6.1)
- o use (simple!) configure script in combination with Unix Makefile
- very soon (6.0 or 6.1)
- o MSDOS/WIN32/others: detection of "reserved" names (= names of character
- devices, or system extensions that look like a characters device driver);
- with the goal of emitting "meaningful" error messages and/or rename
- queries.
- (Currently, these reserved names are catched as "non-deletable files".)
- o redesign "file exists -- is newer/older -- overwrite/skip/rename"
- logic in extract.c and the corresponding system specific mapname()
- services; to prevent superfluous decryption key prompts for entry
- that will be skipped, later.
- o rewrite to use fread/fseek/etc. [eventually: test
- write(bytes) vs. fwrite(words), especially on Crays/Alphas]
- soon (probably in conjunction with multi-part handling)
- o incorporate new backfill version of inflate()
- wait for zlib version
- o check NEXTBYTE for EOF in crypt.c, funzip.c and explode.c, too
- whenever
- o add option to force completely non-interactive operation (no queries
- for overwrite/rename, password, etc.); also allow some sort of non-
- interactive password provision? (file? command-line? env. variable?)
- someday?
- o add testing of extra fields (if have CRC)
- later
- o rewrite to allow use as a filter
- way, way later...
- o add Unix hard-link support?
- way, way later...
- o add option to search zipfile contents for a string and print the
- results? ("zipgrep" option--e.g., unzip -g or unzip -S) (easy for
- fixed strings, hard for wildcards/true regex's)
- way, way later, if at all...probably use libregex
- o add -y "display symlinks" option to zipinfo? various sorting options?
- (-St date/time, -Sn name)?
- who knows
- o add "in-depth" option to zipinfo? (check local headers against
- central, etc.)--make it a better debugging tool (or just create
- zipfix)
- who knows (zip -F, -FF already exist)
- Some maintance or OS specific topics for 6.0 release:
- * add "unix-style-path -> partitioned-dataset filename" conversion to MVS port
- * should we add support for (null) entry names (empty entry name field), to
- conform to the PKWARE specification?
- =======================================
- Requested features:
- - extract or exclude on basis of UID [Armin Bub, Armin.Bub@bk.bosch.de, 970904]
- =======================================
- o miscellaneous little stuff: whenever
- --------------------------
- - change DOS -f/-u stuff to use DOS API for getting filetimes, not stat()
- - add (-N?) option to lose all user input and/or switch to "(*input)()"
- function, replaceable by UzpAltMain() param
- - add -@ option to read from stdin (zip) or from file (PKZIP)? (go32 built-in)
- - add -oo option to overwrite OS/2 and DOS system and hidden files, too
- - add option to compute MD5 checksum on files and/or on entire zipfile?
- - decide whether to use WinGUI "skipping" diagnostics in extract.c
- - combine "y/n/A/N" query/response stuff into unified section with query
- function(s) (InputFn?)
- - disable ^V code in remaining mapname() routines
- - change filename-matching logic so case-insensitive if case-sensitive fails?
- - allow multiple dir creation with -d option? [Bob Maynard]
- - use gcc -pg, gprof to do profiling on unzip
- - Doug Patriarche (doug.patriarche.bvdhp01@nt.com) Northern Telecom Canada Ltd.
- "I need to do a port of zip/unzip for Wind River Systems' VxWorks OS"
- [GRR: 15 March 95 -> "early June"]
- Features from old BUGS file (mostly duplicates of other entries above):
- - ignore case for internal filename match on non-Unix systems, unless file-
- specs enclosed in single quotes
- - modify to decompress input stream if part of a pipe, but continue using
- central directory if not (BIG job!)--extended local header capability
- - add zipinfo option(s) to sort alphabetically, by date/time, in reverse, etc.
- - when listing filenames, use '?' for non-printables? [Thomas Wolff, 92.6.1]
- - add zipinfo "in-depth" option? (check local vs. central filenames, etc.)
- - create zipcat program to concatenate zipfiles
- - add -oo option (overwrite and override)? no user queries (if bad password,
- skip file; if disk full, take default action; if VMS special on non-VMS,
- unpack anyway; etc.)
- - add -Q[Q[Q]] option (quiet mode on comments, cautions, warnings and errors)?
- forget -oo, or make synonym? Default level -Q?
