[postgis-devel] Garden test is failing on 1.4

[Obe, Regina]

Ah okay.  More scary - I was able to crash my 1.3.5SVN test with this
garden test.  But my 1.3.5SVN has a mishmush of stuff so hopefully its
just isolated to me.  

Well its good we are going thru this exercise.  I've just revised the
garden script so when you output the results its easier to see where it
failed. Also cleaned up the xsl garden sql generator to use an array of
geometry sets so much less repetitive and easier to expand on.

I was testing the script with
psql -U postgres -d testpostgis -f gardentest.sql -o gardenoutput.txt

and it failed as it was getting to here

SELECT 'ST_LineMerge LineSet: Start Testing Multi/LINESTRING'; 
BEGIN; 
		
SELECT ST_AsEWKT(ST_LineMerge(the_geom)),
	ST_AsEWKT(ST_LineMerge(ST_Multi(the_geom)))
		  
		FROM ((SELECT
ST_MakeLine(ST_SetSRID(ST_Point(i,j),4326),ST_SetSRID(ST_Point(j,i),4326
))  As the_geom 
		FROM generate_series(-60,50,10) As i 
			CROSS JOIN generate_series(40,70, 10) As j)) As
foo;  
COMMIT;
SELECT 'ST_LineMerge LineSet: End Testing Multi/LINESTRING';

Yeah, it looks as if I was a little bit too eager in removing some of 
the old code - I removed a section that was required to set the array 
type. Since this determines the memory alignment used for the array 
elements, PostgreSQL was getting confused. Please test latest SVN where 
you should find this is now fixed.

Yeah, the JTS stuff got ripped out from trunk a long time ago...


ATB,
