#12437 closed defect (fixed)

support multiple etag values in `no-tile-header`

Reported by: bastiK Owned by: team

Description

Currently, the following does not work:

<entry>
    <name>Mapbox Satellite</name>
    ...
    <no-tile-header name="ETag" value="&quot;067736a547cafe90014b4e59b6510abe&quot;" />
    <no-tile-header name="ETag" value="&quot;ee1f6802b0234046b553cbbc672ac7d9&quot;" />
    <no-tile-header name="ETag" value="&quot;9f5a2f1d7cc131e58befc2052c71c827&quot;" />
</entry>

It only respects the last entry.

(As a workaround one can use regexp, e.g.

    <no-tile-header name='ETag' value='"067736a547cafe90014b4e59b6510abe"|"ee1f6802b0234046b553cbbc672ac7d9"|"9f5a2f1d7cc131e58befc2052c71c827"' />

)

Milestone: 16.02
Resolution: fixed
Status: newclosed

See #12425.

comment:2 by stoecker, 8 years ago

In 9613/josm:

fix #12437 - see #12425 - fix handling of equal no tile headers with different values - hope the related josm config change does not break anything

comment:3 by stoecker, 8 years ago

Resolution: fixed
Status: closedreopened

Preferences saving needs to be fixed.

comment:4 by stoecker, 8 years ago

In 9617/josm:

see #12437 - support new Map<String, List<String>> type in preferences

comment:5 by stoecker, 8 years ago

Now only conversion of old preferences is needed. But as this setting is anyway overwritten with the Maps stuff maybe that's unnecessary?

comment:6 by wiktorn, 8 years ago

In 9619/josm:

Finish removal of tile-size workaround code started in [9617].

Now WMTS TileSources with other than 256px tile size should work properly.
See #12437, #12186

Fix name of "valid-georeference", so it will be properly loaded from preferences

Seems nobody complains :-)

comment:8 by wiktorn, 8 years ago

Please check #12474

In 9713/josm:

see #12437 see #12474 - Add (failing) unit tests

What about using MultiMap<String, String> instead of Map<String, List<String>> (→r9617)?

comment:11 by stoecker, 8 years ago

Ah I overlooked that we have our own implementation. Yes. Why not.

I'd leave the Prefs implementation of Map<String, List<String>>, as it does no harm.

Is MultiMap correctly handled in prefs?

comment:12 by bastiK, 8 years ago

I would stick to Map<String, List<String>> as it uses only standard collections and does the same job as MultiMap.

comment:13 by simon04, 8 years ago

The problem with supporting Map<String, String> as well as Map<String, List<String>> are unchecked assignments as demonstrated with testDeserializeStructTicket12474 in r9713. The shape of the string (in the preference XML file) determines the type in Java which leads to #12474/ClassCastException w/o any compiler error/warning.

That's only an issue when like here the preferences are changed and not updated as I left out the rewriting of existing prefs. Simple solution is to add a rewrite of the old entry in our preferences update section. But I'm still not sure how the two reports managed to get into that state, as the wrong entry normally gets immediately overwritten with a new correct one from the maps file.

You failing test simply says: Our deserializer isn't stable against JSON not matching the expectations. That's independent from the question what structure we use.

I fixed the prefs, but not your failing test.

You are right, this doesn't work. It is kind of funny, we cannot even catch this kind of error proactively. Instead it will blow up somewhere in the calling code like a parcel bomb. This can be easily avoided by switching to MultiMap (or any other class != Map).

Type erasure is really one of the worst things in Java...
