recently-added items may tend towards the top). Not all of these
represent user-visible changes.
-* Honor `Content-Disposition: XXX; filename="FILE"' when creating the
- file name. If possible, try not to break `-nc' and friends when
- doing that.
+* Change the file name generation logic so that redirects can't dictate
+ file names (but redirects should still be followed). By default, file
+ names should be generated only from the URL the user provided. However,
+ with an appropriate flag, Wget will allow the remote server to specify
+ the file name, either through redirection (as is always the case now)
+ or via the increasingly popular header `Content-Disposition: XXX;
+ filename="FILE"'. The file name should be generated and displayed
+ *after* processing the server's response, not before, as it is done now.
+ This will allow trivial implementation of -nc, of O_EXCL when opening
+ the file, --html-extension will stop being a horrible hack, and so on.
+
+* -O should be respected, with no exceptions. It should work in
+ conjunction with -N and -k. (This is hard to achieve in the current
+ code base.) Ancillary files, such as directory listings and such,
+ should be downloaded either directly to memory, or to /tmp.
+
+* Implement digest and NTLM authorization for proxies. This is harder
+ than it seems because it requires some rethinking of the HTTP code.
+
+* Rethink the interaction between recur.c (the recursive download code)
+ and HTTP/FTP code. Ideally, the downloading code should have a way
+ to retrieve a file and, optionally, to specify a list of URLs for
+ continuing the "recursive" download. FTP code will surely benefit
+ from such a restructuring because its current incarnation is way too
+ smart for its own good.
+
+* Both HTTP and FTP connections should be first-class objects that can
+ be reused after a download is done. Currently information about both
+ is kept implicitly on the stack, and forgotten after each download.
+
+* Restructure the FTP code to remove massive amounts of code duplication
+ and repetition. Remove all the "intelligence" and make it work as
+ outlined in the previous bullet.
+
+* Add support for SFTP. Teach Wget about newer features of FTP servers
+ in general.
+
+* Use FTP features for checking MD5 sums and implementing truly robust
+ downloads.
* Wget shouldn't delete rejected files that were not downloaded, but
just found on disk because of `-nc'. For example, `wget -r -nc
removing any of the existing HTML files.
* Be careful not to lose username/password information given for the
- URL on the command line.
+ URL on the command line. For example,
+ wget -r http://username:password@server/path/ should send that
+ username and password to all content under /path/ (this is apparently
+ what browsers do).
+
+* Don't send credentials using "Basic" authorization before the server
+ has a chance to tell us that it supports Digest or NTLM!
* 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).
+ the server at the desired endpoint would work). For example,
+ --range=n-m would specify inclusive range (a la the Range header),
+ and --range=n:m would specify exclusive range (a la Python's
+ slices). -c should work with --range by assuming the range is
+ partially downloaded on disk, and contuing from there (effectively
+ requesting a smaller range).
* 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.
+ This should be easy provided the above restructuring of FTP code that
+ would include the FTP connection becoming a first-class objects.
* Try to devise a scheme so that, when password is unknown, Wget asks
the user for one.
* --retr-symlinks should cause wget to traverse links to directories too.
* Make wget return non-zero status in more situations, like incorrect HTTP auth.
+ Create and document different exit statuses for different errors.
* 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.
* Make `-k' check for files that were downloaded in the past and convert links
to them in newly-downloaded documents.
+* Devise a way for options to have effect on a per-URL basis. This is very
+ natural for some options, such as --post-data. It could be implemented
+ simply by having more than one struct options.
+
* Add option to clobber existing file names (no `.N' suffixes).
-* Add option to only list wildcard matches without doing the download.
+* Add option to only list wildcard matches without doing the download. The same
+ could be generalized to support something like apt's --print-uri.
* Handle MIME types correctly. There should be an option to (not)
retrieve files based on MIME types, e.g. `--accept-types=image/*'.
-* Allow time-stamping by arbitrary date.
+* Allow time-stamping by arbitrary date. For example,
+ wget --if-modified-after DATE URL.
-* 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.
+* Make quota apply to single files, preferrably so that the download of an
+ oversized file is not attempted at all.
-* Download to .in* when mirroring.
+* When updating an existing mirror, download to temporary files (such as .in*)
+ and rename the file after the download is done.
* Add an option to delete or move no-longer-existent files when mirroring.
-* 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.
+* Implement uploading (--upload=FILE URL?) in FTP and HTTP. A beginning of
+ this is available in the form of --post-file, but it should be expanded to
+ be really useful.
* Make HTTP timestamping use If-Modified-Since facility.
-* Add more protocols (e.g. gopher and news), implementing them in a
- modular fashion.
+* Add more protocols (such as news or possibly some of the streaming
+ protocols), implementing them in a modular fashion.
* Add a "rollback" option to have continued retrieval throw away a
configurable number of bytes at the end of a file before resuming
