This item has been reassigned from the project mldonkey, a multi-networks file-sharing client task tracker to your tracker.

The original report is still available at task #5904

[field #10]                  Summary: shell:// type url for rss feeds
[field #11]      Original Submission: Ive made a small patch for rss feeds, so shell:// style urls can be used.

I wanted this so I could get broken rss feeds, and fix them up with xmllint first.

There are of course pros and cons to this.
Pro:
- mldonkey dont need to deal with each and every brokeness out there. feed them first through xmllint or whatever
- rss feeds can be synthesized from web pages( i have a couple of these already)

Con:
- maybe opens new security holes

The cons could be handled the same way as for the "!" command(my patch currently doesnt). Pango has a pach for a security enhanced "!" command, which could be refactored to be used with this shell:// extension. The idea is that this extension wont cause more trouble than the existing "!" command, if done properly.

here is what the patch looks like:

in commonweb:

rename mldonkey_wget to mldonkey_wget_url

let mldonkey_wget_shell url f =

    Sys.command (Printf.sprintf "%s > %s" command filename);                                                                                                                                                                                                                       
    (f filename : unit)
