Requery during downloading disabled?

Hi Limewire-ers, I just joined the core-dev email list to post the question below but noticed that this forum seems to be more active; should I communicate with the Limewire development team here (forum) or through core-dev which doesn't seem to be as active? I'll post my questions here for now, and appreciate any insights into these issues (and also happy to hear the best way to talk with developers... forum or email lists?). Brian

Hello everyone, I've been working with are recent Limewire CVS
snapshot and noticed that when a search and attempt to download
finally enters the tryAllDownloads3() method of the ManagedDownloader
class that it actually stops the ability to re-query (perform any
more searches for that piece of content). Specifically, it appears
that when the

while (true) { ... }

portion of tryAllDownloads3() is entered the ability to continue
searching comes to a halt. I am attempting to optimize, if possible,
the search process so that a requery can be issued even while the
download is in progress. To do this, I tried to re-query from within
the while (true) loop of the tryAllDownloads3() method, but that
caused an exception and stopped it entirely.

Is it possible, given the way Limewire is currently coded, to requery
while a download is in progress?

On a similar note (possibly related), I noticed that when I use a
magnet link that has as its "xs" source a standard Web link
(not a Limewire client, but instead a web link) Limewire will only
download from that web site and won't bother to query the network. I
wonder if this is related to the fact that Limewire can start the
download from the web site immediately, and in doing so it enters
tryAllDownloads3() before it actually has a chance to query the
Gnutella network? Following, for example, is the type of magnet link
that I try (not a real one) but for which only one source is allowed
(that source being the http:// web site; nothing from the Gnutella
network is available):

magnet:?xt=urn:sha1:EI66YQYRH47K73NNFPSQDUV&dn=Som eMusicFile&xs=http://somwhere.com/path/thefile.mp3

Magnet's such as the above only download from the web site specified
by xs, but don't use the Gnutella network -- is that related to the
issue of re-query being disabled during downloads or do you think
these are two separate issues?

Ideally I'd like to specify a number of sources for xs (so that the
download can start from multiple web sites), which Limewire will use
to start the download while it queries the larger Gnutell network. Is
this possible given the way Limewire is designed today?

With thanks for any advice you might have on these two issues,

Brian
