recently-added items may tend towards the top). Not all of these

|

* 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

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.

* 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
