Free space

[Vabavia]

It will be very usefull to see how math free space left on current drive, when I adding an torrent download. Sorry for my English.

[livings124]

The OS can show you this information - adding it else where is a bit bloaty.

[mezz]

I agree about OS can show you the info, but since Transmission now included daemon/web stuff. I think it will be useful to have this feature, that way one of us can tell how much space left before add torrent in WebUI. :-)

[elagon]

I agree with mezz, with remote interfaces this could be very usefull

[theCrank]

I agree with mezz and elagon. The WebUI could use such a feature, you can't always access your server and check your free space (no ssh-client available, ...). I'm not thinking about a mechanism that stops me from adding new torrents, when the disk is nearly full, but only a small hint that warns me, somewhere in the "add torrent" window.

here's how php does this portably

[Elbandi]

We use OS quota for limit the disk space. So i made a little patch: daemon can query the current quota status. if there is no quota or query failed, fallback to diskspace (use statvfs like php). The web interface have a new a bar: displays the current disk/quota usage, soft and hard usage (if diskspace used, soft = hard).

[charles]

Elbandi: what platforms does that work for?

[Elbandi]

charles: i use ubuntu. but every linux have quotactl, statvfs and i think setmntent/getmntent/endmntent calls. And maybe the /etc/mtab file is standard. (or /proc/mounts). But i dont know about OSX or BSD :(

[mezz]

The *BSDs, OS X and Windows don't have /etc/mtab and /proc/mounts, so this patch won't work for these OSs. I actually don't mind you to use this patch if you add some option in build time like enable this feature only on Linux and not other OSs until one of OS port it.

[Elbandi]

In windows i can get the diskspace with ​GetDiskFreeSpaceEx call. But i havent got bsd or osx.

Where can i find some info, how to build transmission in windows?

[charles]

Elbandi: the best person to ask is the person doing the "wintransmisson" project. You can find him ​here.

[Elbandi]

i implement the windows version to get the disk free size. The query function is in platform.c . But i dont know what sould i check in other systems (osx, bsd): #define ????

[Elbandi]

updated the diff to 1.50 beta1

[charles]

Is it really necessary to have all these eight fields? Unless I'm misunderstanding something we really only need to know how much free space is available for use on the disk, and that's just a single field. It's also a simpler & more portable goal than the code in the current patch.

Elbandi: any chance of revising this patch to make it simpler?

[Elbandi]

The "freespace" would be good for a single system (desktop, homerouter), because only one ppl use the disk. And in most cases with gui, and look to disk his disk space.
But the transmission daemon (and the rpc interface) is used in a dedicated server with many users. A good supervisor (like me ;] ) setup quota for this users to prevent to one user eat all disk space... In linux system the diskspace != quota space. So in my solution first query the quota status. If no quota, or query is failed, "fallback" to get diskspace. There is easier in windows, because diskspace == disk quota. (i havent got access to bsd* or osx, so i cant test on that system).

[turbo]

This information/code is also in the #920 patch(es)... Haven't looked at patches in this ticket to see which is best though.

Well, let me put it a different way then... all Transmission really cares about is how much space the user has left that they can use. No matter how we derive that value under the covers, surely that's the only field that needs to be returned back to the RPC clients...

Elbandi: ping

[charles]

Closing this ticket due to lack of interest.

I'd still welcome a patch along the line described in the previous couple of comments. If someone wants to write such a patch, feel free to reopen this ticket....

[Elbandi]

After torrents are having moved anywhere with setlocation, i see no reason to finish this :(

If someone doesnt use setlocation (or disable it), use the patch in this ticket to own build.

[elagon]

Maybe transmission could check the free space of the setlocation destination...

[Elbandi]

hmm, this setlocation checking is a good idea. i made a patch (based my old code), to check the new location, is space for the torrent. If force (boolean) is set true, no checking.

[charles]

seven months have gone by and nobody else has asked for this feature, and there's no consensus on how it should be implemented in the first place.

I'm going to close this ticket as wontfix for now... it seems to be a solution in search of a problem. Maybe this will be needed in the web ui rewrite but for now we don't seem to need it.

[lkraav]

as a side note, ​this is how i implemented functionality in question, but it depends on an external cron job to supply the info. i'd say it's definitely useful, but i don't have a good idea how to do it in a simple x-platform way without external deps.

[charles]

Ticket #2990 has been closed as a duplicate of this ticket.

If someone were to submit a simple, clean and portable patch to implement this, I would use it. The reason I didn't use Elbandi's patch for this was because it failed all three critiera. :(

[charles]

Ticket #3236 has been closed as a duplicate of this ticket.

seven more months have gone by with no new interest in this feature.

Isn't this being tracked in #1212 at the moment? From that one it's clearly a desired feature. Lots of times I add torrents from work or holiday location (on my server at home) and need an indication of how much space is left.
