[mapserver-users] Mapserver 7.0.3 and disabling default extent for WFS

[Rahkonen Jukka (MML)]

If I set "wfs_use_default_extent_for_getfeature" "yes"
I  see a difference
[Tue Dec 20 00:28:37 2016].113723 msOGRFileWhichShapes: Setting spatial filter to -1e+300 -1e+300 1e+300 1e+300
[Tue Dec 20 00:28:48 2016].950696 msOGRFileNextShape: Returning shape=9, tile=0

However, this change does not make is fast, notice 11 seconds between WhichShapes and Next shape.

Jukka,



thanks for spotting my brain damage...



In fact there are 2 issues :

- a minor one: the debug message "Setting spatial filter..." was always displayed, even when the spatial filter wasn't applied

- a major one: the logic to interpret the yes/no value of the setting was inverted (only when it is explicitly set fortunately, so that doesn't break existing mapfiles without the metadata item). I've fixed that, and thus modified the doc to advertize the feature only in 7.0.4. I guess I didn't notice that since I mixed it with other optimizations.
