- use mmap() to read whole files in core instead of allocating memory and read'ing it. - use a new, more general, HTML parser (html-parse.c) and interface to it from Wget (html-url.c). - respect <meta name=robots content=nofollow> (easy with the new HTML parser). - use hash tables instead of linked lists in places where the lists were used to facilitate mappings. - rewrite the code in host.c to be more readable and faster (hash tables instead of home-grown lists.) - make convert_links properly convert partial URLs to complete ones for those URLs that have *not* been downloaded. - use HTTP persistent connections where available. very simple-minded, caches the last connection to the server.

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.
|
|
|
|
* Take a look at
|
|
<http://info.webcrawler.com/mak/projects/robots/norobots-rfc.html>
|
|
and support the new directives.
|
|
|
|
* 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?
|
|
|
|
* 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
|
|
character if it was encoded in the original URL (e.g. %20 but not %7E).
|
|
|
|
* --retr-symlinks should cause wget to traverse links to directories 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.
|
|
|
|
* 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
|
|
'/'.
|
|
|
|
* If CGI output is saved to a file, e.g. cow.cgi?param, -k needs to change the
|
|
'?' to a "%3F" in links to that file to avoid passing part of the filename as
|
|
a parameter.
|
|
|
|
* 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.
|
|
|
|
* Add option to clobber existing file names (no `.N' suffixes).
|
|
|
|
* Introduce a concept of "boolean" options. For instance, every
|
|
boolean option `--foo' would have a `--no-foo' equivalent for
|
|
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.
|
|
|
|
* Handle MIME types correctly. There should be an option to (not)
|
|
retrieve files based on MIME types, e.g. `--accept-types=image/*'.
|
|
|
|
* Implement "persistent" retrieving. In "persistent" mode Wget should
|
|
treat most of the errors as transient.
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
* Add more protocols (e.g. gopher and news), implementing them in a
|
|
modular fashion.
|
|
|
|
* 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.)
|
|
|
|
* Support SSL encryption through SSLeay or OpenSSL.
