[mapserver-users] Multiline string error

[Lime, Steve D (MNIT)]

One quick thing to do would be to take OGR out of the mix. Just set up a mapfile with the feature in question as a WKT inline feature. Something like:

LAYER
  NAME 'badwkt'
  TYPE LINE
  STATUS DEFAULT
  FEATURE
    WKT ' MULTILINESTRING ((-110.220980 38.982832, -110.220887 38.982863, -110.221614 38.982708, -110.220980 38.982832),(-110.220980 38.982832, -110.220887 38.982863, -110.221614 38.982708, -110.220980 38.982832))'
  END
  CLASS
    STYLE COLOR 0 0 0 END
  END
END

Then try to draw... If this fails then it's a MapServer issue.

Steve,

Version 6.4.1 built on the same machine with the same settings does not have the issue.

Steve,

We will add some debug to the OGR read later today or tomorrow.

How do I turn on the maximum debug?

Thanks

Ian

Steve,

OGR connection to SQLITE DB.

How are you submitting the WKT to MapServer? Is it via MapScript, via inline features or some other mechanism?

Devs,

The MULTILINE string below gives the following in mapprimitive.c and then as the first shape has 0 points the msSmallMalloc fails as the size passed to it is -8.

[Wed Aug 13 07:55:10 2014].618971 Shape contains 2 parts.
[Wed Aug 13 07:55:10 2014].618987       Part 0 contains 0 points.
[Wed Aug 13 07:55:10 2014].619001       Part 1 contains 3 points.
[Wed Aug 13 07:55:10 2014].619016               0: (882.383078, 511.333078)
[Wed Aug 13 07:55:10 2014].619032               1: (825.909890, 260.048026)
[Wed Aug 13 07:55:10 2014].619049               2: (882.383078, 511.333078)

Any clues what we should look at next?

This same source data file and layer work with older versions of mapserver 6.

Thanks

Ian

Folks,

With Mapserver 6.5-dev from git and GDAL 1.9.1 the line below either does not draw or causes mapserv to error and not render an image without an error message.

MULTILINESTRING ((-110.220980 38.982832, -110.220887 38.982863, -110.221614 38.982708, -110.220980 38.982832),(-110.220980 38.982832, -110.220887 38.982863, -110.221614 38.982708, -110.220980 38.982832))

Changing the final digit on either of the first or last lats/longs and it draws ok!

Any ideas?

Thanks

Ian
