Hello kind people of Geotools,
After upgrading to Geotools version 9.2 (from 2.7.5) we had a problem
with all our samples because of GEOT-4211 (CQL Filter fails when certain
values are passed).
I took a look at the grammar files and saw that the newly (since 8.x)
added relate filter functionality conflicts with the parsing of
integers.
TOKEN [IGNORE_CASE]:
{
< #DIMENSION_SYMBOL: "*"| "T" | "F" | "0" | "1" | "2"> |
< DE9IM_PATTERN:
<DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL>
>
}
Which overlaps with 9 digit integers existing of only 0, 1 & 2.
If I add left and right square brackets everything works fine, this does
however change the syntax of the Relate function.
TOKEN [IGNORE_CASE]:
{
< #DIMENSION_SYMBOL: "*"| "T" | "F" | "0" | "1" | "2"> |
< DE9IM_PATTERN:
<LSP><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><DIMENSION_SYMBOL><RSP>
>
}
Sample:
RELATE(the_geom, LINESTRING (-134.921387 58.687767, -135.303391
59.092838), T*****FF*)
becomes:
RELATE(the_geom, LINESTRING (-134.921387 58.687767, -135.303391
59.092838), [T*****FF*])
I took brackets because the pattern represents a matrix, but it could
also be something else (quotes for instance (making it a string)).
Thought / Remarks?
If you like I can make a patch, but changing syntax probably needs some
discussion / more formal way of handling, as it will break your code if
you use the relate filter.
Sincerely
