Just Click "Force Download"!
Easy As That

That doesn't work. Duh...

I finally managed to get a reply from a LimeWire Developer:

In the private message, he wrote this:

"We basically don't reply because we don't have time to monitor the forums enough to know that the thread exists. This is because we're working constantly to improve LimeWire, fixing issues such as this. It's really just a constant tradeoff that we have to make -- the more time we spend on the forums and many other places (Gnutella developer groups, for example), the less time we have to write code to make the software better. We try to do the best we can, but it's just a difficult situation because the less time we spend coding, the more people complain about problems with the current version, leading to more time spent discussing those issues with users, which leads to yet less time spent coding, etc. etc.

So, I do apologize that we have not addressed these issues on the forums. There are really only 5 of us, though, and I assure you that we have our hands quite full. I have neglected the forums in the past several weeks to devote more time to writing code, but hopefully I will have some time to devote here fairly soon.

Thanks for your concern."

In one of the threads, he wrote this:

"Thanks for all of the comments. Our apologies for not responding to some of the threads -- we really do have limited resources and have to make a tradeoff between working on the program and answering people's questions or responding to their comments. As you probably know, I and the other LimeWire people who post here are the developers who actually write the software (and there are only five of us!), so it's just a constant battle to try to get to everything!

We are working on the resuming issue in various ways. Actually, we're really tackling it by just improving the general architecture of the network so that resuming will improve along with a bunch of other things. The changes will really be on two fronts: 1) HUGE (Hash/URN Gnutella Extension), as mentioned above, will introduce a really nice scheme for efficiently finding duplicate of file on the network in a really robust way, which will improve resumes when you need to resume from another host and 2) Far better swarmed downloading using HTTP 1.1, which will make resuming an issue less often. This change will significantly improve download speeds.

So, we have at least a couple a neat features coming along in LimeWire 2.3.0 fairly soon. We will also be updating the integrated player at least on OS X to use the native QuickTime API, so you'll get the best sound available on any system, at least on OS X. We may integrate this as an optional download on other platforms as well."

So I guess they are really working on it!

Problem is they've been "working" on this same problem *forever*. LimeWire has always been infamous as one of the worst peers for resuming files - makes it kind of useless for anything larger than a few meg.

Many other gnutella peers (Gnucleus for one) manage this quite well with the current protocol by just having a re-search option to find more sources.

LW tries half-heartedly, but if it can't resume immediately it either overwrites (should never be allowed to happen) or more likely just gives up enitrely. There's nothing more frustrating than having 90% of a 100+ meg file in your download folder, being able to find more sources in a search, but having absolutely no way to use them to resume.

I agree, when I used BearShare it never happened, and it resumed fine.The only reason why I am using LimeWire is Ultrapeer. But I guess they're really trying hard.

This is not an advertisement, but on AG Satellite the resume starts before my browser opens (seems like anyway)and there is no shortage of songs, DL tends to be a bit slower but that's made up in the fact that you don't have to re-DL a file you have 95% of already. Not all of us have 100 gig hard drives, you know. I'll hang onto this program and see if the next version is better but I am totally fed up.

OK, I'm guilty of cluttering this up with the same spammy crap I'm bitchin' about but I can't stand it anymore!!

I'm amazed how many people post nothing more than a whiny compaint about how the folks writing their free software won't answer to their every whim. If you don't like it, go use something else and leave the forums for pointing out legit issues. Maybe they could get to more of the real problems if they didn't have to listen to 100 morons saying nothing more than Waaaa!

On the other hand, the number of people saying "Waaaa" is a good indicator of how serious a problem is. The lack of download resuming in LimeWire seriously degrades its quality; if the developers are at all interested in making a good product, they should fix this problem.

I haven't tested everything completely yet, but I believe I've fixed most of the problems associated with resuming downloads. Below is a patch for the source release currently available at http://download.limewire.org/servlet...wnload&dlID=15.

Some clarifications on my patch above: It fixed two problems with resuming which I observed on my system (RedHat Linux 7.2); I make no guarantees as to how it'll work on your system. The patch will not do anything to let you resume old incomplete files which were on your system before the patched version was installed; it'll only help for new files. Finally, it should be noted that this patch will completely disable the "remove incomplete files after x days" feature; incomplete files will stay until you delete them manually.

More specifically, the patch does two things: Firstly, it removes the "isOld()" check when purging the incomplete file directory, because that check returned true every time for files which were in the process of being downloaded when the check occured. Secondly, it adds a function which loops through and actively stops all active downloads on shutdown. This because data on the downloads wasn't being updated on shutdown, but I noticed that data was updated when I stopped a download manually.

I'm sure there are much better ways of fixing both bugs, but I'll leave that to the real developers.
