Stays silent if download is incomplete cause of timeouts

Reported by: skyper Owned by: GerdP
Priority: normal Milestone:
Component: Plugin reverter Version:
Keywords: template_report incomplete download silent timeout Cc:

Description

What steps will reproduce the problem?

  1. Revert one way and all deleted objects to new layer. I used way and CS 83164338
  2. Get one conflict
  3. Try to select the object in mapview.
  4. Select object with conflict through conflict list panel

What is the expected result?

  • I should be able to select the way in mapview
  • No artifacts going to screen {0,0}

What happens instead?

  • No way to select the way in mapview
  • Artifacts once selected through conflict list panel


Please provide any additional information below. Attach a screenshot if possible.

Did not see this kind of artifact for a while now but here it is (again?). Remembered me about all the trouble changing to ODbL.

Damn, forgot to take the screenshot, and now, I cannot reproduce it. Could it be that the reverter plugin did not download all data cause of communication problems (timeouts)? I know "download parent" does silently fail a lot.

For the selection problem, see similar issue on #13678.

Probably a reverter problem but the same issue is present in core at least with "download (incomplete) members", see #19333.

#19412 and #19566 show that there is a general problem in connection failures.

I am not sure how to handle incomplete reverts. They may be caused by timeouts as well as the user pressing "Cancel".
The plugin doesn't only generate commands, it also adds downloaded objects to the data layer. It is rather easy to show a notification or a popup but it is much more difficult to work out what to do with the data that was already used to update the layer, esp. when multiple changesets are reverted.
I think it would be better to always create a new layer and maybe automatically merge it with the current edit layer if user
requests that.

+1
There is already the option for a new layer which could be reused.
If merge layers works properly, we could rely on it and have reverter only handle the download of objects.

comment:6 by GerdP, 4 years ago

I didn't mean to remove the creation of commands. I like to be able to use undo/redo to see what changed.

  • re-throw OsmTransferException (19582-core.patch)

Replying to GerdP:

I see, understandable and useful. In fact, undo of merge would be useful. Merge layers seems more complicated than merge selection. New ticket?

comment:9 by skyper, 4 years ago

Undo of merge is covered by #7489.

I also stumbled over #19467 which would explain some of my problems with merge layers.

In 35638/osm:

see #19582: Stays silent if download is incomplete cause of timeouts

  • rethrow OsmTransferException instead of only logging a warning so that a popup is shown
  • show a Notification if revert was cancelled, as it sometimes reacts a bit late

This will only improve reverter with JOSM 17920 or later, plugin is compatible with older versions.

I'v e postponed the complex handling of incomplete reverts. Let's see if this helps or not.
