Recommended Posts

1.9 is now 2.0, and we've hit beta!

Release Notes:

[ul][li]We've added UDP tracker support!

[/li][li]uTP has been improved significantly over the previous alpha, with many bugs fixed and performance improvements. It's no longer hidden in Advanced settings.

[/li][li]The setup dialog has been overhauled to make it much easier to use and with a built-in speed test. It's still not quite complete yet, but this will give you a good taste of what we're up to with it!

[/li][li]A new transfer cap feature has been added to track bandwidth usage, along with graphs to show your usage.

[/li][/ul]

Feature Overview:

UDP trackers are a different protocol for tracker communication that uses significantly less processing power on the tracker end. It's important for us to support this because trackers have limited resources, so this should allow them to support many more users with their current hardware and not crash under the load.

uTP is an alternative communication method for BitTorrent traffic that allows the client to automatically regulate its bandwidth usage to avoid adversely impacting your internet connection. This will allow you or other users on the network to download their torrents but still allow others on the network to function with little difference. This does not require any additional setup.

In addition, uTP in this version has added its own form of STUN, a method of getting incoming connections without direct connectivity to the Internet. This allows µTorrent to punch holes through routers and firewalls to increase connectivity and improve speeds. It is even possible to connect two firewalled peers through uTP's NAT traversal feature.

The transfer cap settings were added in response to various users who have ISP-mandated caps on how much data they can download/upload in a month. Now you can track your usage in MB (with a handy graph to visualize it) and even configure µTorrent to stop torrenting once the limits are exceeded. Currently, you can configure the time interval, the data cap and whether it should stop based on only download, upload, or both combined.

As a privacy notice, this traffic data is not sent back to us or anyone.

My observations over the last couple dozen minutes:

Unchecking the option to install uTorrent during the setup disables the Additional Settings panel on the next step, even though those options can be enabled later when you run uTorrent without installing it.

The disabled menu buttons seem to have a 3D border that detracts from the asthetic appeal. Maybe remove that border?

Right clicking on the Remove button while its disabled shows the context menu and makes the Remove button enable itself for a small duration.

The uTorrent help file still shows uTorrent as being v1.8.0. uTorrent 1.8.3 build 15619 shows 15772 in the help file.

The help icon in the Preferences form seems to be resized poorly. White pixels around the edge are visible.

The dialog box thats visible when you hit Help -> Show Statistics has a lot of empty space on the right (in Windows 7 at least).

Similarly, the Preferences form could be made a bit shorter as the longest panel leaves some space down the bottom: http://i30.tinypic.com/2ymdpfm.png

The font for the disabled Scheduler Settings under Scheduler in the Preferences form differs from the enabled font: http://i28.tinypic.com/2v8fn5y.png

Similarly, the font for the Transfer Cap panel under Transfer in the Preferences does the same, as well as the two labels under UI Extras when the "Override automatic [...]" checkbox is unchecked.

In the RSS Downloader form, the left side of the ListView or ListBox item on the Favorites tab doesn't align with the left side of the ListView item on the History tab.

The Setup Guide form seems pretty bare when you first see it. Maybe consolidating the free space is a good idea.

When running a speed test in the Setup Guide form (and after as well), the text for the Suggested Settings panel gets cut off and isn't disabled: http://i30.tinypic.com/21l0eox.png

More Setup Guide inconsistencies: When you dont have a server selected, a dialog box comes up (that arguably shouldn't have a capital S for server) that not only changes the font for the disabled Network Test panel text, but also doesn't disable the "Automatically test your [...]" label (which happens to be too close to the Suggested Settings panel text to begin with - might be causing the previous issue): http://i27.tinypic.com/2qa4dpy.png

If you uncheck Speed Test in the Setup Guide form and hit Run Test, you are unable to run another test with any combination of selected tests checked or unchecked.

When disabled, the Skip Files label in the Create New Torrent dialog has a different font than when enabled.

Creating a new torrent (30MB) takes a very long time (10 seconds). CPU usage was very low (~2%) and never maxed out a single physical core, even though it should have considering the HDD is not the bottleneck.

When a torrent is made of a certain folder, and that folder is subsequently removed, trying to create a torrent of that folder (by just opening the Create New Torrent dialog) leaves the Skip Files label and text box disabled.

Under the Seed While panel in the Torrent Properties dialog, the font for the text that is disabled when the checkbox is unchecked is different than when it is enabled.

The Torrent Properties dialog shows redundant characters (the pipe symbol) in the title when multiple torrents were seleted.

The Add Torrent from URL dialog box's sole label should say ".torrent file", not just ".torrent."

The Logger seems to show certain entries twice:

[2009-08-05 01:28:48]  Loaded ipfilter.dat (0 entries)[2009-08-05 01:28:48]     ***   Starting Diagnostic thread   ***[2009-08-05 01:28:48]  IPv6 is installed[2009-08-05 01:28:48]  Got Teredo Address: xxxxxxx[2009-08-05 01:48:37]  Connecting ...[2009-08-05 01:48:37]  Connecting ...[2009-08-05 01:48:38]  Checking intermediate networks ...[2009-08-05 01:48:38]  Checking intermediate networks ...[2009-08-05 01:48:44]  Running Upload test ...[2009-08-05 01:48:44]  Running Upload test ...[2009-08-05 01:48:58]  Running Download test ...[2009-08-05 01:48:58]  Running Download test ...[2009-08-05 01:49:13]  Starting Test[2009-08-05 01:49:13]  Starting Test[2009-08-05 01:49:13]  Port Forward test complete.

The default width for the columns under Advanced in the Preferences dialog could use some adjusting.

This is my first time upgrading to this beta branch and the first thing I noticed:

The setup still offers to create a quick launch icon on Windows versions that do no longer have it. Quick launch has been removed from Windows 7 and is unlikely to return in future versions of Windows, while offering it has no negative consequences, it just doesn't look polished. Setup needs to check the Windows version and not show this option on Windows 7 or higher.

Oh ... and wouldn't it be time to finally focus on maybe the most important feature in µtorrent? I'm talking, of course, about the tetris easter egg. With higher resolution monitors becoming more and more common it could really use an upgrade to make it more scalable. ;)

v2.0.0.16081 Beta:

Can't install/upgrade from v1.9.15380.

Installer (both normal and uncompressed) crashes everytime I try. WinXP-PRO-SP3-BR updated, dump files:

http://www.mediafire.com/?idtlrjjlzjm

http://www.mediafire.com/?jrfgdwuzudj

http://www.mediafire.com/?c2wmyme0umm

Edit: Managed. Installer needs connection to internet (DNS and TCP). Communication allowed, installer goes OK. :D

I think that installer must run flawlessly even without internet access. (Many ppl installs everything with all internet access blocked, for "general" security reasons)

- HTTP 404 error when d/l new torrents from private tracker and no-go for them. (didn't try on public ones)

- Seeding previously completed torrents in older version are OK til now.

Few questions:

1) Logger stats "*** Starting Diagnostic thread ***" when uT is opened. Should exist a log for "Finnished Diagnostic thread"?

2) What Options-->Preferences-->Advanced-->"allow_pairing" stands for?

3) Options-->Preferences-->BitTorrent-->"Enable bandwidth management" bypasses "bt.transp_disposition"? Enabling is the same as "bt.transp_disposition = 15"?

THANKS.

Yes, it is. However you have to manually set bt.transp_disposition to 13 to allow incoming uTP connections but NOT make outgoing uTP connections. And you'll probably also have to disable a couple advanced settings (bt.tcp_rate_control AND net.calc_overhead) or your upload speed will probably go down when you get a uTP connection. :(

the setup guide needs a complete workup.

- port test - fails 2/3 tests

- test servers - are unsuitable for Europe and middle-east users/tests. the manual selection should be put back. new servers should be definable by the user

- "mixed" results if the server does not respond (atlanta...) :

By rafi_d

UDP trackers - retry - in TCP trackers - when there is a timeout - the retry is about 30-60 sec later. Only after a few quick retries we see the ~20min timeouts.

On the UDP tracker - it does not have any ~30-60 seconds retires, it goes to the ~20 min timeout. It should retry 2-3 more times before that!

Thanks for excellent feedback!

It turns out that we have at least 2 serious bugs. One crash that seems to be related to https trackers, and one where we actually send an incorrect announce to trackers. These are our highest priority right now.

"Just a quick question, what prompted the addition of UDP trackers? Wasn't this something that wasn't stable or a standard?"

OpenTracker has supported it for a while and is a very popular tracker. Using UDP is generally a good idea to bring down load on popular trackers, we want uTorrent to be a good citizen and not hammer trackers. Hopefully client support will be wide spread enough at some point, so that trackers that currently spend 99% of their capacity on misbehaving clients flooding it with HTTP requests can turn that off.

"1) Logger stats "*** Starting Diagnostic thread ***" when uT is opened. Should exist a log for "Finnished Diagnostic thread"?"

The diagnostics thread is a simple thread that monitors the responsiveness of the application. If the application hangs or freezes, it will report some key information about its state to us to help us determine if we have any bugs that might be causing it. These are things like states of mutexes and which threads are waiting on them, to catch dead-locks, and also which windows message we last processed, to give us a hint on which piece of code might be causing the lock-up. The diagnostics thread stays running for the whole lifetime of uTorrent.

"2) What Options-->Preferences-->Advanced-->"allow_pairing" stands for?"

There is a new feature where a local host application or web page can "pair" with uTorrent. This works by the application automatically detect that uTorrent is running, ask it for permission to gain access to it. This will trigger a message box in uTorrent where the user can grant or deny access. If the user grant access, the application can access the webUI from that point on. This is a feature that we anticipate can improve the user experience when using a separate webUI based application. We also have some ideas on applications for this that will come later. The concept is similar to bluetooth pairing, except that it's currently limited to localhost applications for security reasons.

"3) Options-->Preferences-->BitTorrent-->"Enable bandwidth management" bypasses "bt.transp_disposition"? Enabling is the same as "bt.transp_disposition = 15?"

Yes, the checkbox provides a simplified interface to the transp_disposition. If you want more detail control, you can still change the advanced option.

"- test servers - are unsuitable for Europe and middle-east users/tests. the manual selection should be put back. new servers should be definable by the user"

Yes, we are aware of the poor coverage of test servers. For speed tests we are using an academic project called NDT (network diagnostics tool) which is hosted by google's measurement lab servers. We anticipate that the server coverage will improve and cover other continents better in the future.
