- For UnZip 6.0/6.1/who knows:
- ================================
-
- o implement handling of file sizes beyond the 32-bit limit of
- 2GByte (resp. 4GByte), using the new 64-bit extra field extensions
- as defined by PKWARE (this will not get implemented for the present
- 16-bit ports - plain DOS and OS/2 1.x)
-
- top of the list for 6.0!
- UnZip 6.0 is now under development, first betas for Win32 and Unix
- are available
-
- o add multi-part zipfile handling
-
- major feature for 6.0!
-
- could happen for 6.0 - 10/8/2004 EG
-
- o better support for multilingual uses and different codepages;
- support unicode (UTF-8 coded) filenames and comment texts
-
- a requested feature getting more and more important,
- maybe in 6.1
-
- o add new low-level, binary API; rewrite "normal" (command-line) UnZip
- to use it
-
- maybe soon (maybe 6.1)
-
- o use (simple!) configure script in combination with Unix Makefile
-
- very soon (6.0 or 6.1)
-
- may be needed in 6.0 to autodetect large file support - 10/8/2004 EG
-
- o add precautions against extracting files outside the tree below
- the current directory resp. the specified extraction folder.
- (automatically remove absolute path specs from zip entries; emit
- warnings when traversing outside the extraction tree...)
-
- done as of version 5.51
-
- o MSDOS/WIN32/others: detection of "reserved" names (= names of character
- devices, or system extensions that look like a characters device driver)
- at runtime; with the goal of emitting "meaningful" error messages and/or
- rename queries.
- (Currently, these reserved names are catched as "non-deletable files".
- On MSDOS and WIN32, when the RTL stat() function allows to identify
- character devices, the "reserved" names are automatically prefixed with
- an underscore.)
-
- 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 ".ini" file support as a (more elaborate) alternative to the presently
- supported preconfiguring abilities via special environment variables
- (UNZIP on many systems...)?
-
- way, way later (if ever)...
-
- 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 maintenance 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
- --------------------------
-
- - add support for setting directory time stamps to win32 port. This requires
- a solution similar to the UNIX SET_DIR_ATTRIB optional code; maybe, it could
- be combined with the delayed restoring of directory ACLs. Unfortunately,
- the simple version used in the OS/2 case (setting dir time stamp just after
- creating the directory) does not work, because WinNT updates directory
- change times whenever the directory content gets modified (addition,
- deletion, rename, file change), at least for NTFS file systems.
- (SPC, 2000-11-16)
-
- - 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

- [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?
