Please go ahead and apply this patch.
Please also run the install_gisdata.sh script, and confirm that it works
as expected, and that the other applications like UDig work.

Accoring to bin/main.sh the bin/install_gisdata.sh is executed after
bin/install_atlasstyler.sh, so the following patch is open for comments.

Small correction: It is especially annoying that this .fix index is
not even a spatial index - it is used to preserve row order when
editing. As a result the index files are very small.
Can I also ask if there is a "qix" spatial index?
(we will be getting that patch into GeoTools so the solution to
generate a fix file should be viewed as temporary and only needed to
get our live dvd release deadlines).

Hi
1. good news: I debugged AtlasStyler and Geopublisher today a OSGeoLive
system and fixed all the problems reported.
AS and GP now have no more problems when opening a Shapefile without a
.fix spatial index from a read-only drive - it doesn't try to create the
index anymore.
2. The problem with read-only and .fix lies in Geotools, so it affects
uDig also.
3. I created a patch for Geotools
(http://jira.codehaus.org/browse/GEOT-3245) but it is not yet reviewed.
Options are:
A: Get the patch into Geotools and make a new release of Geotools and uDig
Advantage: No big changes on the OSGeo side.
Disadvantage: Lots of work for Jody. uDig, Geopublisher, AtlasStyler and
will not profit from a spatial index when working with the demo
shapefile data.
B: Create .fix indexes during build after the Shapefiles are unzipped
and while the drive is still read-write.
.fix are Geotools-specific, so ogr doesn't create these files. We need a
command line tool to add .fix indexes if we want it to be done in
'bin/loadgisdata.sh'. Such a tool doesn't exists yet... So i added a
command line option to AtlasStyler 1.5 that does exactly that.
So for option B, we have to do only one thing: Add a line to
'bin/install_atlasStyler' that will add a spatial index to all
shapefiles in the $DATA_FOLDER:
find $DATA_FOLDER -iname "*.shp" -exec atlasstyler "addFix={}" \;
This REQUIRES that 'bin/loadgisdata.sh' is run before
install_AtlasStyler.sh is run.
Actually install_Gisdata is setting the data read-only already. So in
the install_AtlasStyler.sh i will have to change the permissions twice..
something not so nice.
Advantage: No quick re-releasing of Geotools and uDig just for one patch
two days after the last release.
Disadvantage: Some unorthodox modifications on the install scripts.
A or B ? Waiting for feedback.
Greetings,
Steve

It is loaded from the naturalearth website directly.
I'm open to you adding .fix files if you think it is easy enough to
achieve.

Hi
I have installed the rc5 to my HDD and started investigating the
problems reported for AtlasStyler and Geopublisher. This is what happens:
The natural earth shapes don't have .fix spatial indexes. AtlasStyler
tries to create them on-the-fly and gets a permission exception.
I will write a fix, so that that will not be a problem anymore, but
maybe we should anyways add .fix files to all Shapefiles on the DVD.
.fix files are supported by Geotools, so uDig, Geoserver,
Geopublisher and AtlasStyler (and probably more) would profit
performance-wise.
The data dir is not in the svn.. Tell me where it is, and i can provide
.fix files for all shapefiles.
Greetings,
Steve
