 Thanks, it seems to compile file now.

 I noticed the addition of the following dependency:

 Is it appropriate if I had the following comment?

 // TODO: replace by java.util.concurrent.ConcurrentHashMap

I dont know anything about this -- where is it used?

[Geotools-devel] Moving to TOPP confluence (Geoserver and Geotools)

2006-03-13 Thread dblasby
TOPP is likely getting a confluence license and setting up a machine to
run it.

I was thinking of moving the Geoserver wiki over to it.  The codehaus
confluence (where its hosted currently) is kinda slow and I find it
difficult/frustrating to edit (or read) pages due to the lag.  Hosting
it ourselves will speed this up and hopefully encourage people to
document.

We're more than willing to also put Geotools on it and, because
geoserver and geotools share a lot of documentation, it makes sense to
keep them together.

I was think we should continue having JIRA and SVN on codehaus, and only
move the wikis over. The wiki's have an export/import command so this
shouldnt be an issue.

What do you think?

dave
ps. Jody -- you put udig on its own confluence so I'd like to hear your
experience.

[Geotools-devel] Geotools 2.2.x -- new stable branch?

2006-03-07 Thread dblasby
I've been talking to several people about the 2.2.x branch and the 2.3
trunk.

From what I've managed to gather, it appears that most of the big
changes are happening on branches and will be (very soon) merging in
trunk.  These merge-ins will be the 2.3 release.  Soon after that - I'm
sure - development for 2.4 will start.  The consensus seems to be about
6 months before you can really trust 2.3.  I am looking forward to
it coming together and being solid.

The 2.2.x branch was started a little while ago.  There wasn't any real
fan-fare to it - the announcement was I took the liberty of creating
the 2.2.x branch..  I was skeptical about its trustworthiness, but
after putting several people several people under the Bright White
Light, they all said that its good.  I know that myself (and others)
spent a lot of time moving all the 2.1.x fixes forward to trunk so they
would be in this release.  Apparently, not much has happened on 2.2.x
(the old trunk) in the last few months except bug fixes.  The people
using it seem to all think its good (if anyone disagrees - please speak
up).

I've also seen several people (including myself) concerned about API
shifts and lack of maintenance.  So, why don't we setup a new stable
branch?   Currently, the stable branch is 2.1.x.  I'd like to see a
place where we can continue improvements where we're not getting our
toes stepped on.  So, I'm proposing making 2.2.x the 'official' stable
branch.

I think this just requires getting an official consensus, but I think
we just need to define what we mean by the 'official stable branch.' 
Here's some ideas:

1. have a big advertisement on the geotools front page that announces
2.2.x as the 'official stable branch'
2. encourage (especially new) users to use the official stable branch
3. encourage users to report bugs against this version
4. encourage users to submit patches against this version
5. recommend people who need to make more substantive changes to use the
unstable (2.3) version and warn them of the implications.

This means the 'official stable branch' isn't something we create and
then immediately forget about - its 'supported'.

The most controversial points will be what changes are allowed to take
place on the stable branch?  Obviously things like changing the
feature model isn't in scope for the stable branch, but I'd still like
to see people able to add/fix things.

The plan would be to keep the 2.2.x branch the stable branch until
2.3 is solid and ready to be the new stable.


The biggest problem is going to be moving changes on the 2.2.x branch
forward to trunk.  This was extremely difficult with 2.1.x, and I'm
betting its going to be quite difficult with 2.2-2.3.  But, I think
the 2.3 changes are going to be focused enough that we can really work
on improving a lot of places around the edges.  I think we should
really define where the changes are taking place on 2.3 so we don't
step on each other.  With a few rules and good communication, I think
we can minimize the pain of moving the changes forward.

What think?

If geotools does make 2.2.x the 'new official stable branch' then I'm
willing to put the time into make a Geoserver 1.3.0-Experimental
release for people to test the current geoserver with the new geotools
stable branch.  Once we've had a few people give it a good kick and
done some in-depth testing (and they all give two thumbs up), we'll
make that the new Geoserver trunk (then start looking at the geoserver
1.4.x changes).

(This is, assuming (confirmed by a few people), that most of the
2.1.x-2.2.x changes are 'syntactical' as opposed to 'conceptual'.)

I'm quite worried that if geotools doesn't have a supported stable
branch that we're going to get ourselves in trouble.  I also think that
having official stability will encourage new users, bug reports, bug
fixes, and documentation.  We really need that!

[Geotools-devel] Re: [Geoserver-devel] Postgis + WKB4J

2006-02-25 Thread dblasby

 No, and I think it _should_ be using the modified jar.  It contains a
 few needed fixes, and the maintainer of the wkb4j stuff has
 disappeared.

JTS has a WKB parser in it (i think since 1.6) -- might be worth
switching to it as its actually being maintained.  Check out JTS's io
package.

Apparently there is an Oracle SDO STRUCT parser in JTS 1.7 too.

And you MUST use the modified WKB4J jar -- the offical WKB4J converts
all your coordinates to floats (instead of keeping them as doubles).

[Geotools-devel] trunk -- gridcoveragerenderering

2005-12-12 Thread dblasby
I've been trying to figure out why the trunk build is failing for me.

The GridCoverageRenderingTests are failing.

It seems to be caused by Do not know how to deep copy  the
org.geotools.coverage.grid.GridCoverage2D in
DefaultAttributeType#duplicate().

I also noticed that the raster symbolizer style ignores the geometry
name property.  The default style has geom as the name, but the code
always looks for grid.

I just made changes that changed the order of querying a bit in the
StreamingRenderer so that it can optimize.  I dont think this would
have broken the Grid rendering stuff (I debugged and everything looks
good).

[Geotools-devel] So, have we given up maintaining 2.1.x??

2005-12-12 Thread dblasby
I'm still trying to improve the rendering  style stuff, but I'm finding
that there are so many API differences (and people running automatic
code style programs) between 2.1.x and trunk that I'm spending almost
all my time moving changes over.  I mean, it takes significantly longer
to move the changes over than it takes to actually do the changes in
the first place.

The truth of the matter is that I really dont want to make any
improvements anymore because its just too painful.  I thought the
entire idea behind the streaming rendering was that we would keep 2.1.x
aligned with trunk.

REMEMBER - EVERY API CHANGE YOU MAKE MEANS I HAVE TO SPEND SEVERAL HOURS
OF WORK ALIGNING THINGS.  Plus more hours keeping changes aligning for
every future change too.

Should we:
1. just say ha ha - fooled you for the people doing rendering (and
other modules) on 2.1.x.  This pretty much means we're calling 2.1.x a
fork.
2. Actually try to announce, vote, and transition API changes.
3. insert your 3rd option

[Geotools-devel] Jalopy and headers

2005-12-06 Thread dblasby
Jody,

I'm not sure what you're saying, but running jalopy (or anything that
mangles the code) isnt a very good idea.

Running Jalopy kills history -- and makes branch-to-branch maintainance
difficult.

I had to waste a good chunk of a day merging changes in
StreamingRenderer.java from 2.1.x to trunk (and back) because someone
ran something that changed almost every line of code in the class.

Chris ran jalopy on something in Geoserver and I just gave up trying to
figure out what had changed (unfortunately his jalopy commit also had
code changes in it).

I'm FIRMLY -1 ; unless someone can argue that those two applications of
jalopy-like stuff will actually save more than a days of someone's time
(+ extra time for how frustrating  futile it is to sort through 10,000
changes).  And this is *just* one java file.  Running it for 3,000
files better save 10 people years!

[Geotools-devel] [Geoserver-devel] Re: data dir

2005-12-05 Thread dblasby
If you look in src\org\vfny\geoserver\util\SLDValidator.java line about
180, you'll see:

File schemaFile = new File(GeoserverDataDirectory
.getGeoserverDataDirectory(servContext),
/data/capabilities/sld/GetMap.xsd);

which would explain why its not finding the schema files!

If you're interested in how the schema validation workings, head down to
line 210 and you'll see the main function.  The only thing intestesting
in the whole file are these lines:

parser.setFeature(http://xml.org/sax/features/validation;, true);   
parser.setFeature(http://apache.org/xml/features/validation/schema;,
true);
parser.setFeature(http://apache.org/xml/features/validation/schema-full-checking;,
false);
parser.setProperty(http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation;,
SchemaUrl);
parser.setProperty(http://apache.org/xml/properties/schema/external-schemaLocation;,
http://www.opengis.net/sld  + SchemaUrl);

These lines:
1. tell the parser to validate the XML document vs the schema
2. does not validate the schema (the GML schema is *not* valid.  This is
an OGC blunder)
3. tells the validator that the tags without a namespace are actually
SLD tags.
4. tells the validator to 'override' the SLD schema that a user may
include with the one inside geoserver.

[Geotools-devel] StreamingRenderer -- requests too many geom columns (+style visitor)

2005-11-16 Thread dblasby
I noticed that the lite/streaming renderer makes some bad assumptions
when you try to render a feature type with multiple geometries in it.

For example, I have a Postgis database with 261 rows (one for each
country in the world).  It has 4 geometry columns in it, one for
varying degrees of generalization:
gen_full -- ungeneralized data (81mb)
gen1 -- 25mb
gen2 -- 10mb
gen3 --  2mb

I then choose which geometry column by using
MinScaleDenominator/MaxScaleDenominator in my SLD file.

So far, everything is great.  But, Geotools makes a little boo-boo in
Lite/StreamRenderer#findStyleAttributes().

It adds ALL the geometry columns (and GRID columns) to the list of
requested attributes.  The JDBC driver pre-fetches 200 rows, so I get
an out-of-memory error even though I'm only rendering about 2mb of
data!

NOTE: 200 rows is basically the entire dataset, so its loading about
81+25+10+2 megs = 128 megs of data!

Here's the code comment on this:

/*
 * GR: if as result of sae.getAttributeNames() ftsAttributes already
contains geometry
 * attribue names, they gets duplicated, wich produces an error in
AbstracDatastore when
 * trying to create a derivate FeatureType. So I'll add the default
geometry only if it is
 * not already present, but: should all the geometric attributes be
added by default? I will
 * add them, but don't really know what's the expected behavior
 */
 ...
 //ALX: For rasters I need even the grid attribute.


 The reason this was done was because, in SLD, you dont have to
explicity declare a reference to the default geometry.

 For example, this symbolizer has an 'invisible' reference to the
default geometry:

 PolygonSymbolizer
Fill
   ...
/Fill
 /PolygonSymbolizer

This one has a direct reference to a geometry (could be the default
geometry, could be a secondary geometry):

 PolygonSymbolizer
GeometryPropertyNamemygeometry/PropertyName/Geometry
Fill
   ...
/Fill
 /PolygonSymbolizer

I imagine there is a 'default' GRID-geometry for the RasterSymbolizer
too.

A simple way of dealing with is to have the style visitor have a flag
for defaultGeometryUsed and defaultGridUsed.  Then, instead of
adding all geometrygrid types to the Query we only add the explicitly
referenced ones (Geometry.../Geometry) and add in the default
Geometry  Grid property if (1) it wasnt already explicitly referenced
and (2) the appropriate flag was set in the style visiting.

This will cut down the Query so its only pulling in geometry/grid
columns that it explictly needs.  I dont think this will affect anyone
- but someone could have code that relies on this incorrect behavior. 
Any code that does this should just make the style visitor know about
their invisible need of a column.


IS THIS GOING TO AFFECT ANYONE?

dave

PS.
Has anyone investigated what happens if you're not using the default
geometry, and you require coordinate reprojection?

Is there something wrong with the SVN repository?  I'm not having any
problems with the geoserver SVN (on codehaus).  I'm using the latest
version of subclipe.

[Geotools-devel] RE: [Geotools-gt2-users] Styling external graphic based on feature attribute

2005-11-08 Thread dblasby

 Anybody had a chance to formulate an answer to this one yet?
..
In other words, the graphic that should be used to render the feature
would be something like http://somehost/somepath?id=fid

Unfortunately, the SLD spec does not allow for this - it only allows for
a  simple xlink:simpleLink instead of one that you could build up.

You could, however, modify the SLD parser and renderers to do something
like this; it would be a medium-difficulty thing to do this.

Is this something to do with me or are other having this problem?

This is a brand new checkout of trunk.

[Geotools-devel] PostGIS features issue

2005-10-20 Thread dblasby
Alessio,

I fixed GEOT-734 (this issue) on branch and trunk.

I'm unable to compile trunk at the moment, but it should be working...

Could you check to make sure its working for you?

I figured this out - I just had to do a full build. Silly me.

I was just confused when it said that it had problems downloading
something when it meant I needed to build it...

Re: [Geotools-devel] Postgis test take 10 minutes!! (PostgisDataStoreAPIOnlineTest)

2005-10-20 Thread dblasby
James/Paul,

Does the auto-testing (ie. paul's nightly build and james' on-commit
testing) do the full test?

I just want to make sure that the test are actually being run somewhere!

I just changed one line of the postgis driver (to put quotes around a
column name), and it took over an hour to run the tests.

I pay for the internet by the minute!!

dave
ps. I'm in thailand, but my internet connections is reasonable - usually
20k/s, but with high latency.  Martin said it took him 20 minutes.

[Geotools-devel] [jira] Created: (GEOT-733) shapefile -- multiple transactions corrupt

2005-10-19 Thread dblasby (JIRA)
shapefile -- multiple transactions corrupt
--

 Key: GEOT-733
 URL: http://jira.codehaus.org/browse/GEOT-733
 Project: GeoTools
Type: Bug
  Components: shapefile  
 Reporter: dblasby
 Assigned to: Ian Wolfe Schneider 


[EMAIL PROTECTED]:
My question is how will they scale with multiple users? I wanted to deploy 
using the shapefile configured GeoServer, but I started noticing problems when 
using it with multiple clients. Sometimes a shapefile would get corrupted and 
contain duplicate entries. The main advantage to using this configuration is 
that it is easier to distribute. If I went with PostGIS, I would need to do 
some remote administration, which is difficult for this application.

[Geotools-devel] Re: [Geoserver-users] shapefiles getting corrupted

2005-10-19 Thread dblasby
This is obviously a *BIG* problem if shapefiles are no longer
transactionally safe.

I setup a geotools bug:

[Geotools-devel] [Geoserver-devel] PostGIS features issue

2005-10-19 Thread dblasby
Looks like the postgis datastore fid-mapper isnt quoting its column
names.

I made this bug report:

http://jira.codehaus.org/browse/GEOT-734

I'll take a quick look at it.

[Geotools-devel] SLDStyleFactory TextStyle2D -- issues

2005-10-07 Thread dblasby
I was attempting to write documentation for label placement (plus fix
all the inconsistencies with the spec), and I noticed some problems
with the SLDStyleFactory and TextStyle2D.

It turns out the SLDStyleFactory is actually trying to do [poor] label
placement (see around line 570)! This also results in a loss of
information if you're using a LinePlacement element in your SLD.


1. remove the placement code from SLDStyleFactory!
2. get rid of the AbsoluteLineDisplacement stuff and replace it with
something that represents PointPlacement/LinePlacement elements in
the TextSymbolizer.

The current implementation seems to try to convert a LinePlacement and
an actual line into a PointPlacement (and setting the
AbsoluteLineDisplacement flag)!! This should be done by the real
labeling code.

This change could affect the j2d renderer as it appears to use the
AbsoluteLineDisplacement flag.

I think Martin Davis (JTS) is wanting to add a bunch of coverage
topology operations to JTS/JCS/JUMP.  There's already a some in JCS
(Java Conflation Suite) and JUMP.

[Geotools-devel] LiteRenderer questions.

2005-09-22 Thread dblasby
Alessio,

I dont know anything about the Raster stuff, but you should be using
StreamingRenderer instead of LiteRenderer.

There's only a few minor differences between StreamingRenderer and
LiteRenderer.  StreamingRenderer is the new LiteRenderer, and is the
one that people in the future will be maintaining.

Switching over to it should be almost trivial.  See the documentation at
the top of lite.Renderer.java or GTRenderer.java interfaces.
