MirrorManager mirrorlist parameters

[Ricky Zhou]

Hi!

Would it be possible to have mirrorlist take arch/release/type
parameters as well?  (Where type is something like dvd, live, kde live,
and maybe even rescuecd, diskboot, etc.)  This way, we could have a
convenient download form redirecting to the mirrors at get-fedora.html.

Thanks,
Ricky

Specifically what did you have in mind?  We might be able to do this 
with mod_rewrite.

Well, I'd like to have
http://mirrors.fp.o.org/mirrorlist?arch=i386&release=f7&type=dvd&...
Return a mirror with .../releases/7/Fedora/i386/iso/F-7-i386-DVD.iso and
http://mirrors.fp.o.org/mirrorlist?arch=i386&release=f7&type=live...
go to .../releases/7/Live/i386/iso/F-7-i386-DVD.iso, and so on.

Since this would be  designed to be "form-friendly," I'm not sure that a
rewrite can extract the parameters (in arbitary order and so on) and
perform all of the necessary logic (although if it is possible, then I'm
completely fine with it).

Thanks,
Ricky

Interesting idea. The database doesn't know anything about file
"types" right now, pretty intentionally.  Doesn't mean we can't add
such, but that will add complexity and possibly additional maintenance
burdens.

How would you expect to handle sets of media (e.g. downloading 3 CD
ISOs that are in the releases/7/Fedora/i386/iso/ directory as opposed
to a single DVD ISO)?

Hmm, good point.  I was thinking that the form could specify
a file path
such as:

filepath=/pub/fedora/linux/releases/%(rel)s/Fedora/$(arch)s/iso/F-$(rel)s-$(arch)-DVD.iso

And the script would substitute the proper values based on the rel/arch
parameters.  For sets of media, the filepath would go to the directory
containing all of the images.  

I'm mostly unsure about how spins/the get-fedora page will work (and if
the directory structures/spin names will remain consistent between
releases), so depending on these factors, it might or might not be
useful.  

Thanks,
Ricky

You can specify
redirect=1&path=pub/fedora/linux/releases/7/Fedora/i386/iso/....iso 
already, and it works.  If some javascript creates that URL, cool.
However, as I've learned, paths do change, and code that generates
paths then needs to change too.

Tell you what.  For the F7 and F8 get-fedora page, let's just be
simple and put hardcoded links to the content, in a table format to
make it clear.  We can then look to do fancier things in the future.
I don't want to make a bunch of MM changes at this point in the F8
release if I can avoid it.

Thanks,
Matt
