[mapserver-users] Regular expression error

[Richard Greenwood]

Steve,

Yeah, the map draws fine. Maybe even too fine because it draws with a
query sting of:
   ogc_fid=430454
and a validation string of:
  'filter_validation_pattern'  'ogc_fid.'
which doesn't look right.

But I'm still looking at what initially caught my attention - hundreds
of mapserver ERRORFILE entries:
  msValidateParameter(): Regular expression error. Parameter pattern
validation failed.

and I'm beginning to think that it's a Windows versus Linux issue.
With the same map file, data and requests I'm seeing the errors in the
Windows instances but not the Linux instances. Do the Windows and
Linux builds use different regex lib's? Again, these are all either
6.0.2 or 6.0.3.

It's not a show stopper but I'd like to figure out if it's me, or my
data, or a mapserver bug. And I'm kind of anal about my log files...

Thanks,
Rich

But regardless of whether I use your validation & filter or mine, I'm getting 20 errors in my MS_ERRORFILE from that layer when there is no filter=value in the querystring. The layer's status is off in the map file, I'm not requesting it in the query string. I just do a mode=map requesting a different layer and my MS_ERRORFILE has this:
