For UnZip 6.1/who knows: |
================================ |
|
o add extraction support for other compression algorithms used by new |
PKZIP, WinZIP, 7-Zip versions |
- LZMA, compression type 14 (most important, because of its efficiency) |
- PPMd, compression type 98 (maybe, less important) |
- WavPacked, compression type 97 (maybe, less important) |
|
LZMA is first-level priority for 6.1, other formats may be taken |
into consideration |
|
o add support for reading AES encrypted archives |
- WinZIP format (priority 1) |
- PKZip format (priority 2) |
|
top level item for 6.1 |
|
o add multi-part zipfile handling |
|
major feature for 6.x! |
|
could happen for 6.1 |
|
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, |
- partially done for the Windows port in 6.0 |
(support restricted for chars of the current system codepage) |
- partially done (beta state) for Unix |
(requires native codepage to be UTF-8) |
|
o complete support for UTF-8 coded entry names (and comments) |
- add new "win32_wide" port to extend unicode support on Windows |
beyond the restrictions of the current (ANSI) system codepage |
- revise/extend the WinDLL interface to allow passing of "wide" |
string argument data |
- add simple built-in character translation between UTF-8 and the |
old (ISO-8851-1 / IBM850) code pages to allow old systems without |
standard UTF-8 support to read UTF-8 encoded archives. |
- extend the built-in translation tables to support other language |
regions besides "Western_Latin1" (e.g. Russian-kyrillic, Japanese, |
Chinese) |
- streamline the multilingual codepage and UTF-8 support for the UNIX |
port (standard codepage translation facility?, like WideChar<->AnsiCP |
translation functions under MS Windows) |
|
should happen for 6.1 |
(there is internal alpha-state code for better "wide" support on |
Windows available at the time of the 6.0 release) |
|
o revise the "extended charcodes" handling in decryption password to |
support UTF-8 encoding on Unicode-aware systems where the "native" |
character coding is NOT UTF-8 (e.g. Windows). |
|
o revise the command line interface for more compatibility with Zip' |
command parser |
- implement the versatile command parser from Zip 3.0. |
- add "long option" definitions for all existing options; revise |
the UnZip user manual to document the long-option alternatives. |
- add support for reading the "process these entries" and the "skip |
these entries" pattern lists from a file (or from separate files ?). |
- add a (long) option to switch off UnZip's internal pattern matching |
on filename arguments. |
|
probably in 6.1, |
(first prototype of the revised command parser was available at the |
time of the 6.0 release) |
|
o add command line options for miscellaneous features requested by users |
and/or development team members: |
- display the Info-ZIP software license |
- more fine-tuning for file attributes set/restored at extraction, like: |
set/clear archive attribute on DOS/OS2/WIN32; |
apply/skip standard or user-defined umask filter on UNIX (& Unix-alike) |
- additional time-stamp related processing filters |
- more listing display modifications |
- overriding the default date-time display style |
- ... |
|
All these options are of minor importance and/or would collide with |
existing "one-character" options. The current UnZip maintainer does not |
want to reserve any of the few not-yet-occupied short option characters. |
for one of these features. So, any implementation effort for items |
of this feature wish-list has to be delayed until the "long option" |
support of the revised command line parser becomes available. |
|
some option may get implemented in 6.1 |
|
o support for |
and/or development team members: |
|
o add new low-level, binary API; rewrite "normal" (command-line) UnZip |
to use it |
|
maybe soon (maybe 6.1) |
|
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? |
|

|
======================================= |
|
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 |

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? |
