reverter plugin broken

[malenki]

What steps will reproduce the problem?

1. Run JOSM
2. create new data layer
3. press ctrl-shift-t
4. enter a changeset number (I used 12188821)
5. press [revert]

What is the expected result?
A changeset gets reverted

What happens instead?
Exception

-> missing lat/lon infos in delete node:

<delete>

<node id="19376053" changeset="12188821" user="Folken" uid="22471" visible="false" timestamp="2012-07-11T18:28:44Z" version="4"/>

</delete>

[anonymous]

​http://www.openstreetmap.org/api/0.6/node/19376053/3 would be ok

Probably a side effect of ​http://git.openstreetmap.org/rails.git/commit/2c67c079ac39cefd3b096524fc0b7364b0eb21d7

[anonymous]

Error message in stack trace above: Mandatory attribute "lat" missing (in line 1.532, col 134)

[Cobra]

fix: find the earliest modified version of each changed node in the changeset, fetch the one before (in case a node was moved, uploaded, deleted, uploaded in the same changeset).

[simon04]

Ticket #7854 has been marked as a duplicate of this ticket.

[NE2]

Because of this API change I can't revert this: ​http://www.openstreetmap.org/?lat=41.625&lon=-87.7686&zoom=14&layers=M

[rickmastfan67]

Yes, this plugin needs to be fixed ASAP in my opinion.

[ToeBee]

Yeah, this is kind of a big deal. I gave it a go and was able to fix the initial parsing of the changeset XML but then it still errored out later while retrieving the history of some nodes. In that case the NullPointerException came from somewhere within core instead of the plugin itself at which point I gave up for the night.

I did find out that the OsmChangesetContentParser class is copy/pasted from josm core except it has some uid parsing removed from it. Not sure what's up with that...

[anonymous]

Added 2 file attachments for reverter/corehacks directory, which are just slightly adjusted copies of the corresponding core classes.
Tried this out in changeset #12440114. Handle with care, though, this might not work at all if multiple versions of a node occur in a changeset. Rgds, mmd

[Don-vip]

I just fixed it in [o28503]. Looks like we had the same idea at the same time ;)

[anonymous]

CS 12246562 fails with an HTTP 403 error message, as one of the nodes has been redacted.

[malenki]

Confirm anonymous comment 11.
Besides: IMO the revert plugin should not try to revert changesets created by the redaction bot.
If a user tries this let it just give a message like: "I won't do that! And you know that I am right!" :)
(Maybe realise this with an easy logic like "if changeset created by Redaction Bot; do ...")

[NE2]

I still get an error when trying to revert changeset 12131373.

Replying to NE2:

Can you please detail the error you have ? I need at least to know if it occurs in plugin or in JOSM core (the exact message and stacktrace are always welcome)

Versions 1-2 are clean, then a non-agreer added some tags or moved the node. Finally user "Schulwegplaner" deleted the object (probably replacing it with a new node). So all that needs to be done by the redaction bot, in order to get a clean history, is hiding the "tainted" version 3.

I'm also getting an error when trying to revert 12582787. I don't know if it's the same problem.

I have made some changes in #7934 (r5408, r5409, r5410).

Can you tell me, guys, if you still have errors when trying to revert changesets with latest JOSM ? If so, do not forget to :

• give the changeset number
• attach the .osm file you have and screenshots if relevant
• give the full stacktrace in an exception occurs.

Thanks.

Empty error message while reverting changeset of redaction bot

[malenki]

The initial mentioned changeset gets reverted fine now.

There is still an issue when boldly trying to revert a changeset created by the redaction bot. Josm gives an error message without error message (I tried it with changeset 12277671):

(see also screenshot)

Is there anything speaking against the handling of redaction bot changesets like this: If changeset created by redaction bot, then print message: "Won't revert changeset nr. XY since it was created due to the license change by Redaction Bot."?

[NE2]

I still can't revert changeset 12131373.
An unexpected exception occurred that may have come from the 'reverter' plugin. According to the information within the plugin, the author is Upliner. Try updating to the newest version of this plugin before reporting a bug. Should the plugin be disabled?

[malenki]

Replying to NE2:

"can't revert" and "may have come from" is not something which I'd call a valid bug report. See Don-vip's comment above.
Additionally I can't reproduce the unrevertability of changeset 12131373.

[rickmastfan67]

I think I know why NE2 is still having problems. He's still using the "tested" version of JOSM per his recent uploads to OSM.

So, NE2, upgrade your copy to [5448], and you shouldn't have anymore problems. ;)

[NE2]

Replying to malenki:

"can't revert" and "may have come from" is not something which I'd call a valid bug report. See Don-vip's comment above.

Buh? That's the bloody error message JOSM gives. However, since I'm using the tested version, I'll give the latest one a try when I get a chance.

[Cobra]

I've recognised that you simply copy-pasted the error message. Usually there's a "report problem" button which gives all the information needed by the developers. Most of the time the stack trace is the important piece of information.

[NE2]

Yeah, that seems to work, though I still get the "star" of nodes without coordinates.

New issue: how am I supposed to revert ​http://www.openstreetmap.org/browse/way/10670746/history to version 1? 2 and 3 are "redacted".

[Don-vip]

Should be fixed in [o29553] (JOSM latest required).
