[Mapserver-users] Seg fault with labels

Hi all,
I'm running Mapserver 4.0.2 on Mandrake Linux 9.2. It was built with the
help of the redhat 9 guide in the wiki. Thanks to the guy who put that
together!
I'm having problems with labelling layers. Mapserver works beautifully
providing I don't try to use labels. If I do (either using bitmap or
truetype), I get Internal Server Error. Running the query at the command
line using the QUERY_STRING debug, I get a seg fault.
This suggests to me a problem with my freetype or gd libraries - I'm using:
freetype-1.3.1-20mdk.rpm, libfreetype6-2.1.4-6mdk and gd-2.0.15
My mapserv -v is:
MapServer version 4.0.2 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF
SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT
SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT INPUT=JPEG INPUT=POSTGIS INPUT=OGR
INPUT=GDAL INPUT=SHAPEFILE
I've tried to run ./configure without freetype, but it still compiles the
libraries in and I get the same result.
Anybody got any bright ideas?!
Thanks in advance
Matt.

Thanks - that is very helpful!

Things seem fine, but you need to create georeference data for the
images in a way that can be used - the JPG files could have world files
(.JGW files) or the TIF files could have world files (.TFW) but you need
them. You need to create these world files. You should try to read the
coordinates from the shapefile (use shpdump) and you need to calculate
the values for the world files. With only three files you can
relatively easily do this by hand.
=20
The shapefile polygons should give you the upper-left corner coordinate
of each tile, and you should be able to calculate the size of each pixel
in X and Y units from the shapefile polygons and information about how
many pixels wide and high each image is (use tiffinfo).

It would help if you could explain what you're trying to do! =20
ok, i'll try tou explain you my situation!
What
format are the raster files in now,=20
The raster files are in jpg format. They are a set of 3 tiles NOT
GEOREFERENCED (of course, they are jpg!). But, i have a shapefile,
called tile.shp (so, georeferenced) representing the footprints of the
tiles. In tile.shp, I created a field (Path) including the absoulte path
to tiff tiles on my disk (ex. /var/www/.....F4-C4.tif).Now, i converted
the jpg files in tiff files, without the world files. I use this mapfile
configuration:
LAYER
NAME "pannelli"
STATUS ON
TYPE RASTER
TILEINDEX "./tile.shp"
TILEITEM "Path"
END
I run maplab, but an error occurs: unable to open tiff files:
Description=09
Unable to open world file for reading. in
/maplab/htdocs/common/wrapper/drawmap.php=09
Failed to draw layer named 'pannelli'. in

Unable to open world file for reading. in
/maplab/htdocs/common/wrapper/drawmap.php=09
Failed to draw layer named 'pannelli'. in

So, i created some empty world files! This time, maplab runs without
error, but it doesn't show me the tiles. It shows me only a blank page.
Where is the problem?
and what geographic reference data
do you have for them (and in what format)?

Adam,
Invoking GPC externally via an ascii file interface may be too slow
depending
on your needs but it is certainly doable.
From a more general point of view, it is my hope to interface the GEOS
library (http://geos.refractions.net) with OGR at some point with a
convenient
mechanism to convert OGR geometries into a form usable in GEOS. So from my
point of view a GEOS is the "future" of complex geometry operations in
OGR (and indirectly shapelib). In fact, I would like to see a nice SWIG'ed
interface to GEOS so that it can be easily used in most/all of the mapscript
supported languages.
GEOS is the library used by PostGIS for geometry operations, but it is
independent of PostGIS. I think it does more than GPC. I was also slightly
soured on GPC because of problematic licensing issues as I recall.
So, if you have a particular need that is satisfied by passing geometries to
GPC then by all means go ahead. However, I don't forsee it as being of
strategic value. If you are interested in cooperating on swigged interfaces
for GEOS and closer integration with OGR, Shapelib or MapServer geometries
then perhaps we could get something going. I hadn't really been intending
to get started on this yet though, so you might get stuck doing quite a bit
of the heavy lifting.
Best regards,

Jason,
GDAL read Arc/Info binary grid files in .adf format and can export a
variety of formats including Arc/Info ASCII Grid format which is ... ASCII.
eg.
gdal_translate -of AAIGrid in_cov/w001001.adf out.grd

Subject: [Mapserver-users] RE: [postgis-users] RE: gone are my query results
Thanks for your reply, Gregory. I'm forwarding this onto the MS folks to
see if they have any pearls of wisdom.
Everything looks great in the db. If I render a map, I see all the points
correctly. If I take that query and plug it in to the command line, I see
the rows. But the moment I try to do either a cgi query, WFS query, or a
PHP query, I get nothing back. No error message.
I'm actually getting panicky which isn't any fun. Has anyone seen anything
like this before?
Queries rely on OID's and SRID's. Is there any way they could have gotten
mucked up? Can I somehow refresh them?
Thanks,
Charlton

If you do the query directly to postgres (via psql or pgAdmin or whatever)
does the query return results ?
If so, then my guess is that this is not a database error, at least not
directly. If ot then yes, it would seem that somehow the postGIS itself has
gottent snarfled.
The change you made relating the geometryColumns doesn't sound to me like
it should effect queries unless somehow the SRID info for the tables in your
mapserver queries got clobbered; should be easy enough to confirm that this
data is ok.
I am not familiar enough with PHP and mapserver to have a clue; does the
mapserver log itself show anything ?
Not much help, I'm afraid, but perhaps posting this to the MMS list would

Subject: gone are my query results
Hi, folks:
Bizarre and unnerving problem here.
Up until last night, mapping was fine and point-query was fine. Now it
appears that the mapping is still great, but the point query and WFS are
toast. I don't get any errors in pgsql.log or php.log. I get . . .
nothing. Even going mapserv cgi query returns empty for a query I know
should work.
Maybe I'm being taught a lesson. In a separate database, I noticed that
addgeometrycolumn was taking too long -- I create about 400 smaller tables
per day. So I commented out fix_geometry_columns(); from the
addgeometrycolumn function and did it once I had finished creating all my
new tables. So am I paying the price? Has this corrupted this database as
well as my other?
If all this is OID stuff, is there any way to refresh all OID's?
Restarted . . . yes. VACUUM and ANALYZE'd . . . yes.
Thanks,
Charlton

Subject: [Mapserver-users] RE: [postgis-users] RE: gone are my query results
If you turn on the logging of statements in postgres and run the mapserver
side of things, does the query show up in the logs ?
If the query does not appear then I'd suspect networking or permissions or
some darn thing keeping postgres from ever seeing the query.
It it does show up then maybe the problem is in the return trip to MS or in
the processing of that data (perhaps your OID suspicions), since it sounds
as if the query itself can be processed.
Any changes to *anything* on either server and anything in between ? (not
likely but always worth ruling out)
Or, shot in the dark, something messing with TOLERANCE so no points are
selected in a query ?
Very puzzling, I agree.

Subject: [Mapserver-users] RE: [postgis-users] RE: gone are my query results
OK, Greg, I think we might be onto something. But it still looks very grim.
I turned on all the logging, and I notice that MS sends it this query:
LOCATION: pg_parse_query, postgres.c:464
LOG: 00000: statement: DECLARE mycursor BINARY CURSOR FOR SELECT
temperature_celcius::text,asbinary(force_collection(force_2d(the_geom)),'NDR
'),OID::text from sst_map WHERE (date_trunc('hour',report_time_stamp +
interval '1 hour' * -04) = date_trunc('hour',timestamp without time zone
'2004-05-01 22:00:00') and (label_z <= 5 or label_z is null)) and (the_geom
&& setSRID( 'BOX3D(-83.0454044480208 24.3838940085927,-82.6541628156105
24.775135641003)'::BOX3D,find_srid('','sst_map','the_geom') ))
OK. That's good. Because if I stick the SELECT part at a psql prompt, I
get back the row I want. And I also notice that its OID is 2185295089.
But if I look at the last sql statement in the log, it's another cursor, but
the OID is wrong.
LOCATION: pg_parse_query, postgres.c:464
LOG: 00000: statement: DECLARE mycursor BINARY CURSOR FOR SELECT
station_id::text,time_stamp::text,z::text,label_z::text,temperature_celcius:
:text,temperature_fahrenheit::text,value_temperature_celcius::text,value_tem
perature_fahrenheit::text,lon::text,lat::text,title::text,institution::text,
institution_url::text,institution_dods_url::text,source::text,refs::text,con
tact::text,report_time_stamp::text,asbinary(force_collection(force_2d(the_ge
om)),'NDR') from sst_map WHERE OID = 2147483647
So had they kept the OID, I would be in good shape.
This isn't looking good!!!

Got your back, Charlton :)
The problem is that your PostgreSQL oids are larger than the mapserver
row number variable can store. The oid is larger than a signed 32 bit
integer can store.
So, solution.
Do not use oid as your "unique" field. Make use of the "using unique"
clause in your data statement, and reference a different unique field
in your table. Make sure that field is indexed. If you have loaded your
data with shp2pgsql, you probably have a 'gid' field you can use that
is a primary key (and therefore already indexed).
Yours,
Paul
