The progress counter (& bar) always shows 0% for every torrent in Qt client.

[dmitry]

Hi.

I use Qt version as remote client (OpenSuSE 12.2). This error appeared after upgrade Qt Client from version 2.73 to 2.74.

Web client (ver. 2.74) and transmission-remote-cli work without this error.

I'm not seeing this bug. Do you have any more information on how to reproduce this issue?

Is the transmission session you're connecting to running the same version of Transmission?

Hi.

This issue reproduce in the pair: transmission-daemon (OpenSuSE 12.2, ver.2.73 or 2.74 or 2.75) and transmission-Qt (OpenSuSE 12.2, ver.2.74 or 2.75 and NOT 2.73). All applications (2.73-2.75) are compiled to SuSE rpm with the same spec-file (but not in the same time).

My current configuration is the pair: transmission-daemon (2.75) - transmission-Qt (2.73) now. I want to recompile transmission-Qt 2.73 with the actual version devel libraries to test.

Hi.

I want to recompile transmission-Qt 2.73 with the actual version devel libraries to test.

Nothing changes.

Recompiled Transmission-Qt 2.73 is working version without any issues. The test torrent (paused) show info: 2,44 GB of 4,65 GB (52,4%) and a bar have a half of full length.

But in Transmission-Qt 2.75, the same torrent show info: 2,44 GB of 4,65 GB (0,00%) and a bar have a zero length. This issue present only on the main window. In torrent properties window another info: 2,44 GB of 4,65 GB (52,4%), 91,72 MB Unverified.

Hmm, there were no changes at all in the Qt code between 2.73, 2.74, and 2.75.

If it were a Qt client issue, I don't understand why it works for you in 2.73.

If it were a libtransmission issue, I don't understand why it works for you in the Web Client.

Does transmission-remote -l show the correct percentages in either 2.73 or 2.75?

Hi.

Hmm, there were no changes at all in the Qt code between 2.73, 2.74, and 2.75.

This is locale issue! The LANG=en_US.UTF-8 transmission-qt removes all problems (for 2.74, 2.75). My current locale is ru_RU.UTF-8.

Does transmission-remote -l show the correct percentages in either 2.73 or 2.75?

Yes, transmission-remote remotehost:9091 -l show the correct percetages.

[jordan]

Interesting. Hmm....

Transmission swapped JSON engines between 2.73 and 2.75, and since we're talking about locales now I suspect that may have something to do with it, then. Perhaps you've got some characters in the JSON that the new engine isn't handling correctly.

So here's a way you could test that theory: Start up transmission 2.73 with all the torrents paused, then try transmission-remote --debug -l 2>t273.json. Then exit the daemon, start up transmission-daemon 2.75, and try transmission-remote --debug -l 2>t275.json. Then you can diff t273.json and t275.json to see if there are any differences in what the two engines are generating.

Hi.

Then you can diff t273.json and t275.json to see if there are any differences in what the two engines are generating.

Nothing of interest:

diff t273.json t275.json

Please note, that in transmission-Qt 2.75 in the main window shows the progress 0%, and in the torrent properties window - real non zero progress %%, simultaneously.

Additionally in 2.75, for torrents in seeding state: the "Ratio" always show 0,00 in main window, and... real non zero value in the torrent properties window, simultaneously.

I can confirm the same issue on transmission-qt 2.75 ArchLinux? x86_64 on multiple machines. I also can see the progress bars when launching with LANG=C

[jordan]

mtorromeo, could you test with a nightly trunk tarball from ​http://build.transmissionbt.com/?

JSON building/parsing have gone through a lot of code changes over the last month in trunk (not 2.7x).

[jordan]

mtorromeo, ping

[dmitry]

Hi. I tested the trunk versions r13789 and r13821. Both versions work as before. The problem disappears if you do start a program like this:

LANG=C transmission-qt

[mtorromeo]

I may be able to test a recent build this weekend if it will still be needed, I doubt I will have time before that, sorry!

[jordan]

When I use LANG=C transmission-qt, I don't see the problem. (As expected.)

But when I use LANG=ru_RU.UTF-8 transmission-qt, I don't see the problem either.

So if this is a locale issue, I'd ask again for help on how I can reproduce the error here.

[taem]

I also confirm this issue for the latest trunk r13847. With LANG=C, T works as expected.

[jordan]

This is fixed now in r13861. I've added unit tests to prevent future regressions on this bug.
