Verifying local data via web interface

[bratok]

Ok, guys this is a weird issue. I have googled and browsed support tickets but I can't seem to find a solution.
I was hoping one of you guys here can help. Here is what's happening:

Whenever I add a new torrent using the web interface, transmission does not start downloading.
Instead it starts verifying non-existing (since it's a new download no data pre-exists) local data.
This is an extremely slow procedure, even though I'm running Transmission on a fast machine (i7 cpu, SSD drive, lots of RAM, dedicated torrent box).
Now, and this is where things really get weird, if I "physically" control the machine that transmission runs on (either via mouse, keyboard or remote control) and focus on the Transmission app (e.g. clicking the window to the front, aka application focus), then suddenly it stops verifying local data and starts the download.

This ONLY occurs using the web interface. It happens with various builds, I'm currently running Transmission 2.82 on Mavericks 10.9.2.

Any ideas?

Yep! I have noticed the same exact issue. I thought I was going crazy. I am using Transmission 2.82 on Mavericks 10.9.2. I am getting a very long "verifying local data" when adding torrents via the web interface or when added to my watch folder automatically via RSS feed (Automatic). This process would've probably have taken hours (was at like 3% after 10-15 minutes), but when VNC'd into the machine it started to download immediately. When not in active use, I Ieave my computer logged in, but at the Login Window (fast user switching). By VNC'ing in, logging in and bringing Transmission into focus started the torrent as it was very slowly "verifying local data". I think we need to submit a bug report on this one.

Ok, so I did a little more testing on this. This is happening when the user account is logged in (and transmission is running in the background) but at the Login Window via fast user switching. When this is the case, either uploading a torrent to the watch folder or adding via the web interface results in extremely slow "verifying local data" that could take days to complete (I never let it go long enough to see if it actually starts). When I re-enter my password at Login Window to resume the session, the torrent starts immediately. I was able to replicate this many times.

Bratok, are you adding torrents to your server with the account logged in but at the "Login Window" (via fast user switching) screen?

Is Transmission development dead? I haven't heard one remark about this and there has been no updates in almost a year. I guess it's time to move to a different torrent client.

Hi interconnect, I'm not adding via fast user switching. The client machine running Chrome which I use to access the web interface, does run fast user switching but not the server that has Transmission running.

I think I'm moving to another client as well since Transmission seems slow if not dead.

I spot some activity though on Trac (issue tracker).

Thanks for filing the ticket interconnect!

Actually, I had fast user switching enabled on the server after all, disabled now, let's see if it solves the issue...

Meh, just noticed this thread now (started a new one). I'm having the exact same problem (and VNC solution), and it was working fine just some days ago. Only thing that could be the issue was that I upgraded to Mavericks on my server. Did you guys find a solution for this?

I'm sure it has something to do with Mavericks because I didn't have this problem in Mountain Lion or earlier. The only solution I've found is just to not have the computer at the Login Window. Unfortunately, the Transmission developers don't seem to care about this issue at all despite it being a major bug in functionality. They have yet to comment or even acknowledge it's existence.

Yeah it could be Mavericks, been trying to play around with users settings but to no use. I don't have the computer at the Login window so that doesn't help me unfortunately. But yeah, it's a shame that the devs hasn't looked into this.

So you're experiencing this with the machine just sitting at the desktop?

Yeah, I have my server (which is connected to the TV) on with just some programs running (Plex, Transmission, Air Video etc). And even if I add the torrents via the web ui or just drop them from my other computer in my watch folder it just sits there verifying. Until I log in via VNC, then it starts right away. So crazy.

Oh wow. I have not seen that happen. I've only experienced it when my machine is at the Login Window... If I log in or connect via VNC, it starts up right away. I've left the machine at the desktop when I'm away and torrents have started up normally. Weird!

Also, I originally thought that this may be because of AppNap... So I tried disabling it (Get Info on Transmission app in Applications folder and you can disable in there) but didn't seem to fix it, however I didn't have much time to play with it.

So I did a little testing on this last night. I had my machine download a few torrents via RSS automatically but had it sitting at the desktop (screen saver was on) and I observed the very slow verifying. So I guess fast user switching has nothing to do with this. The computer was just at the desktop, with Transmission running, blank screensaver was on at the time. I observed the very slowing verifying state by using the Transmission web interface. I physically went to the machine and brought out of screen saver and torrent immediately verified and started downloading. This bug is even more critical now than before.
