Example of overlapping changesets (#10) for CS 27169290 (timeout) and 27169302: two nodes created, then modified.

Summary

Achavi is not showing the two created notes of CS 27169290.

  • Changeset timestamps
    <changeset id="27169290" ... created_at="2014-12-02T00:01:56Z" closed_at="2014-12-02T01:02:13Z" ...>
    <changeset id="27169302" ... created_at="2014-12-02T00:02:35Z" closed_at="2014-12-02T00:02:35Z" ...>
    27169290 was edited in Potlatch and closed automatically after a timeout of one hour. The following 27169302 closed immediately and falls within the timestamp range of the first
  • The actual changes are first create in CS 27169290 then modify in CS 27169302 (nodes moved)
    <create><node id="3215109947" changeset="27169290" timestamp="2014-12-02T00:01:56Z" version="1" visible="true" user="..." uid="2146151" lat="46.0793512" lon="14.4970048">
    <modify><node id="3215109947" changeset="27169302" timestamp="2014-12-02T00:02:35Z" version="2" visible="true" user="..." uid="2146151" lat="46.0793619" lon="14.4970154">
    (It's the same for both nodes, just showing the first as an example here)
  • but the Achavi adiff query [adiff:"2014-12-02T00:01:55Z","2014-12-02T01:02:13Z"] for 27169290 only returns aggregated changes as changeset 27169302 (type="create" + version="2"), which is filtered out client-side
    <action type="create"><node id="3215109947" lat="46.0793619" lon="14.4970154" version="2" timestamp="2014-12-02T00:02:35Z" changeset="27169302" uid="2146151" user="...">
  • the last edit of 27169290 was at timestamp="2014-12-02T00:02:13Z":
    <create><node id="3215113580" changeset="27169290" timestamp="2014-12-02T00:02:13Z" version="1" ...>
  • and the adiff query without timeout [adiff:"2014-12-02T00:01:55Z","2014-12-02T00:02:13Z"] would return the changes as intended:
    <action type="create"><node id="3215109947" lat="46.0793512" lon="14.4970048" version="1" timestamp="2014-12-02T00:01:56Z" changeset="27169290" uid="2146151" user="...">

So the changeset edits don't actually overlap, only the changeset metadata time ranges because of the timeout:

 27169290  00:01:56 - 01:02:13  Potlatch
           00:02:13             last change (timeout, no overlap)
 27169302  00:02:35 - 00:02:35  iD

Data

(user replaced with "...", same user for both changesets)
