Hey Emacs, this is -*- outline -*- mode
-This is the to-do list for Wget. There is no timetable of when we plan to
-implement these features -- this is just a list of things it'd be nice to see in
-Wget. Patches to implement any of these items would be gladly accepted. The
-items are not listed in any particular order (except that recently-added items
-may tend towards the top). Not all of these represent user-visible changes.
+This is the to-do list for Wget. There is no timetable of when we
+plan to implement these features -- this is just a list of features
+we'd like to see in Wget, as well as a list of problems that need
+fixing. Patches to implement these items are likely to be accepted.
+The items are not listed in any particular order (except that
+recently-added items may tend towards the top). Not all of these
+represent user-visible changes.
+
+* Currently Wget mirrors remote FTP permissions whenever it retrieves
+ the directory listing. This is undesirable for most users, as
+ permissions like "664" are frequently used on the servers, which
+ might not be what the user wants. Wget should be changed not to
+ mirror remote FTP permissions by default. There should be a new
+ option add an option that enables this back on.
+
+* Implement a `--disable-dns-cache' option that disables DNS caching.
+ It is trivial to implement; simply avoid calling cache_host_lookup
+ at the end of lookup_host.
+
+* Honor `Content-Disposition: XXX; filename="FILE"' when creating the
+ file name.
+
+* Should allow retries with multiple downloads when using -O on
+ regular files. As the source comment says: "A possible solution to
+ [rewind not working with multiple downloads] would be to remember
+ the file position in the output document and to seek to that
+ position, instead of rewinding."
+
+* Wget shouldn't delete rejected files that were not downloaded, but
+ just found on disk because of `-nc'. For example, `wget -r -nc
+ -A.gif URL' should allow the user to get all the GIFs without
+ removing any of the existing HTML files.
+
+* Be careful not to lose username/password information given for the
+ URL on the command line.
+
+* Add a --range parameter allowing you to explicitly specify a range of bytes to
+ get from a file over HTTP (FTP only supports ranges ending at the end of the
+ file, though forcibly disconnecting from the server at the desired endpoint
+ might be workable).
+
+* If multiple FTP URLs are specified that are on the same host, Wget should
+ re-use the connection rather than opening a new one for each file.
+
+* Try to devise a scheme so that, when password is unknown, Wget asks
+ the user for one.
+
+* If -c used with -N, check to make sure a file hasn't changed on the server
+ before "continuing" to download it (preventing a bogus hybrid file).
+
+* Generalize --html-extension to something like --mime-extensions and have it
+ look at mime.types/mimecap file for preferred extension. Non-HTML files with
+ filenames changed this way would be re-downloaded each time despite -N unless
+ .orig files were saved for them. Since .orig would contain the same data as
+ non-.orig, the latter could be just a link to the former. Another possibility
+ would be to implement a per-directory database called something like
+ .wget_url_mapping containing URLs and their corresponding filenames.
* When spanning hosts, there's no way to say that you are only interested in
files in a certain directory on _one_ of the hosts (-I and -X apply to all).
Perhaps -I and -X should take an optional hostname before the directory?
-* When simplifying paths, wget needs to stop at any '?' character.
-
* Add an option to not encode special characters like ' ' and '~' when saving
local files. Would be good to have a mode that encodes all special characters
(as now), one that encodes none (as above), and one that only encodes a
* --retr-symlinks should cause wget to traverse links to directories too.
-* Lots of noncompliant webservers issue HTTP redirects to relative URLs, and
- browsers follow them, so wget should too.
-
* Make wget return non-zero status in more situations, like incorrect HTTP auth.
-* Timestamps are sometimes not copied over on files retrieved by FTP.
-
-* Wget does not currently handle "fragment identifiers" (the part of a URL
- starting with the '#' character) properly.
-
* Make -K compare X.orig to X and move the former on top of the latter if
they're the same, rather than leaving identical .orig files laying around.
-* Allow mirroring of FTP URLs where logging in puts you somewhere else besides
- '/'.
-
-* Make `-k' convert <base href=...> too.
-
* Make `-k' check for files that were downloaded in the past and convert links
to them in newly-downloaded documents.
-* -k should convert convert relative references to absolute if not downloaded.
-
-* -k should convert "hostless absolute" URLs, like <A HREF="/index.html">.
- However, Brian McMahon <bm@iucr.org> wants the old incorrect behavior to still
- be available as an option, as he depends on it to allow mirrors of his site to
- send CGI queries to his original site, but still get graphics off of the
- mirror site. Perhaps this would be better dealt with by adding an option to
- tell -k not to convert certain URL patterns?
-
* Add option to clobber existing file names (no `.N' suffixes).
* Introduce a concept of "boolean" options. For instance, every
turning it off. Get rid of `--foo=no' stuff. Short options would
be handled as `-x' vs. `-nx'.
-* Implement "thermometer" display (not all that hard; use an
- alternative show_progress() if the output goes to a terminal.)
-
* Add option to only list wildcard matches without doing the download.
* Add case-insensitivity as an option.
* Allow time-stamping by arbitrary date.
-* Fix Unix directory parser to allow for spaces in file names.
-
* Allow size limit to files (perhaps with an option to download oversize files
up through the limit or not at all, to get more functionality than [u]limit.
-* Recognize HTML comments correctly. Add more options for handling
- bogus HTML found all over the 'net.
-
-* Implement breadth-first retrieval.
-
* Download to .in* when mirroring.
* Add an option to delete or move no-longer-existent files when mirroring.
-* Implement a switch to avoid downloading multiple files (e.g. x and x.gz).
-
* Implement uploading (--upload URL?) in FTP and HTTP.
* Rewrite FTP code to allow for easy addition of new commands. It
should probably be coded as a simple DFA engine.
-* Recognize more FTP servers (VMS).
-
* Make HTTP timestamping use If-Modified-Since facility.
* Implement better spider options.
* Implement a concept of "packages" a la mirror.
-* Implement correct RFC1808 URL parsing.
-
-* Implement HTTP cookies.
-
-* Implement more HTTP/1.1 bells and whistles (ETag, Content-MD5 etc.)
+* Add a "rollback" option to have continued retrieval throw away a
+ configurable number of bytes at the end of a file before resuming
+ download. Apparently, some stupid proxies insert a "transfer
+ interrupted" string we need to get rid of.
-* Support SSL encryption through SSLeay or OpenSSL.
+* When using --accept and --reject, you can end up with empty directories. Have
+ Wget any such at the end.
