Subject: [Tilecache] Securing TileCache
Message-ID: <ca7da9120912070925q59bfaba6o5505ab54b1fa35ef@mail.gmail.com>

Hi

I recently wrote a tutorial providing the basics for securing
TileCache layers with Pylons and repoze.what. It basically involves
executing TileCache as a WSGI app within a Pylons controller, and
securing access to this controller using Pylons-specific decorators
from repoze.what.

Just thought I could share this tutorial here on the TileCache mailing list.

<http://www.mapfish.org/doc/tutorials/secure_tilecache.html>

Cheers,

PS: thank you TC developers for providing a WSGI interface, this is great!

Hi all,

I'm getting the same error.

the install success and I get tile when I visit:
http://example.com/yourdir/tilecache.cgi/1.0.0/basic/0/0/0.png

then I test a Mapnik layer
tilecache.cfg:
  [basic_mapnik]
  type=MapnikLayer
   mapfile=/var/www/wms/data/xml_mapnik/world/world_styles.xml

which refer to a simple example from mapnik using borderline
world_styles.xml:
  <?xml version="1.0" encoding="utf-8"?>
  <!DOCTYPE Map>
  <Map bgcolor="steelblue" srs="+proj=latlong +datum=WGS84">

    <Style name="My Style">
      <Rule>
        <PolygonSymbolizer>
          <CssParameter name="fill">#f2eff9</CssParameter>
        </PolygonSymbolizer>
        <LineSymbolizer>
          <CssParameter name="stroke">rgb(90%,50%,20%)</CssParameter>
          <CssParameter name="stroke-width">0.1</CssParameter>
        </LineSymbolizer>
      </Rule>
    </Style>

    <Layer name="world" srs="+proj=latlong +datum=WGS84">
      <StyleName>My Style</StyleName>
      <Datasource>
        <Parameter name="type">shape</Parameter>
        <Parameter
name="file">/var/www/wms/data/shp/world/world_borders</Parameter>
      </Datasource>
    </Layer>
  </Map>

then I visit: 
http://example.com/yourdir/tilecache.cgi/1.0.0/basic_mapnik/0/0/0.png
And I get error 500: Internal Server Error
find in the error.log: [Wed Dec 09 23:41:59 2009] [error] [client
192.168.1.135] Premature end of script headers: tilecache.cgi

so I install every things to get TileCache Running Standalone under WSG
then I visit: http://hostname:8080/1.0.0/basic/0/0/0.png I get tile
and change to my mapnik layer
http://hostname:8080/1.0.0/basic_mapnik/0/0/0.png

In the console get the "Segmentation fault" and the server is down...
I also get the error on seeding tile when I run the command:
tilecache_seed.py
Is someone have any idea?

this is my config:
ubuntu server 9.10 (64-bit)
tilecache2.10

Hello Petrus,

Short answer:  Upgrade to Mapnik trunk, or install mapnik from the apt- 
repository.

Long answer: The Mapnik 0.6.1 release suffers from a shapefile reading  
bug that only manifests with newer compilers, like those just added to  
Ubuntu 9.10. We tested on Ubuntu 9.10 beta with no problems but now if  
you build from source you'll hit this bug. I was able to fix this  
problem in the Mapnik 0.6.1 package available for Karmic, so try  
uninstalling your current Mapnik (I assume you installed from source?)  
and re-installing from packages:

That would look like

sudo rm /usr/local/lib/libmapnik.dylib
sudo rm -rf /usr/local/lib/mapnik/ #careful!
and remove the python bindings whose location you can find with:
python -c "import mapnik;print mapnik.__file__"

Then do:

sudo apt-get install python-mapnik

Dane

Hello Dane,

I didn't success to set mapnik, I had already install from the package, so
I'll install ubuntu 8.04.3 ? Hardy Heron ? and test it.

Thanks.

Petrus,

Actually, I think I know the problem.

On Ubuntu Karmic do:

sudo apt-get install python-cairo

Then let me know if that works (with the python-mapnik package in  
Karmic). It looks like a bug specifically in the package, as python- 
cairo is a missing dependency.

Subject: [Tilecache] tilecache layer in arcgis server javascript api
Message-ID: <BAY116-W39D55BFC6348CE3CF24D3CDF890@phx.gbl>


Hi,
I am wondering if anyone has been able to get a custom tile cached layer from TileCache to display correctly in the ArcGIS server javascript api? Or can someone direct me on the proper configuration. This page describes creating a custom tiled layer in the api:
http://resources.esri.com/help/9.3/arcgisserver/apis/javascript/arcgis/help/jssamples_start.htm#jssamples/layers_custom_tiled.html
It seems I need to add the scale and resolutions of my zoom levels. However, I am having difficulty doing this.

This is what my tileinfo looks like:

this.tileInfo = new esri.layers.TileInfo({            "rows" : 512,            "cols" : 512,            "dpi" : 72,            "format" : "JPEG",            "compressionQuality" : 0,            "origin" : {              "x" : -180,              "y" : 90            },            "spatialReference" : {              "wkid" : 4326            },		"lods" : [              {"level" : 0, "resolution" : 0.00014444444444444444444444444444444, "scale": 45497.4416},		  {"level" : 1, "resolution" : 0.000031747816880420907984514989617448, "scale": 10000},              {"level" : 2, "resolution" : 0.000015873908440210453992257494808724, "scale": 5000},              {"level" : 3, "resolution" : 0.00000011023547527923926383512149172725, "scale": 2500}            ]          });

I used this link to compute my resolutions by hand:
http://code.google.com/p/xenia/wiki/TileCache
I actually do seem to be getting back tiles; However, all of them are outside the range of my data and I simply get white tiles. My data bounding box is -77.92,-40.75,-77.79,40.85.
My tile urls look something like this    /0/1216/1380.jpeg   when I think they should look more like this     /0/0/1.jpeg
Thanks in advance for any help on what I may be doing wrong.
Scott

Dane,

I do a quick test and it's working now. in fact python-cairo was missing.

Thank you very much, it's great.

Not entirely sure why you think the tile URLs should look like 0/0/1.jpg when
you've given your origin as -180, -90. Also, you didn't include your tilecache
config. Can you include your tilecache config, and explain why you
think the origin should be what it is?

Chris,
Thank you very much for your reply. Your message helped me get much closer to getting it working (I think). First, I had an error in my bbox where I had a negative latitude value for the bottom instead of a positive 40.75. I adjusted my origin to reflect the left/top of my tile data bbox -77.92/40.85 (instead of the world). I also adjusted the rows and cols parameters to a value of 256. The last change I made was to adjust my getTileUrl function to match the TMS scheme for url's  {z}/{x}/{y}.jpeg I am now getting tiles back that show my data. The only issue now is that the tiles do not seem to match up on my map. More specifically, some of the rows seem mix-matched. Do you have any ideas on why that may be?
Thanks again,Scott
Here is my tilecache layer config:
[centreimagerygeogarc]
type=WMSLayer
url={myurl}
extension=jpeg
layers={mylayer}
bbox=-77.92,40.75,-77.79,40.85
resolutions=0.000144444444444444444,0.000031747816880420907984514989617448,0.000015873908440210453992257494808724,0.00000011023547527923926383512149172725
srs=EPSG:4326
extent_type=loose

and my code:

this.tileInfo = new esri.layers.TileInfo({            "rows" : 256,            "cols" : 256,            "dpi" : 72,            "format" : "JPEG",            "compressionQuality" : 0,            "origin" : {              "x" : -77.92,              "y" : 40.85            },            "spatialReference" : {              "wkid" : 4326            },		"lods" : [		    {"level" : 0, "resolution" : 0.00014444444444444444444444444444444, "scale": 45497.4416},              {"level" : 1, "resolution" : 0.000031747816880420907984514989617448, "scale": 10000},              {"level" : 2, "resolution" : 0.000015873908440210453992257494808724, "scale": 5000},              {"level" : 3, "resolution" : 0.00000011023547527923926383512149172725, "scale": 2500}            ]          });
          this.loaded = true;          this.onLoad(this);        },
        getTileUrl: function(level, row, col) {          return {myserverurl} +                  level + "/" +                  col.toString() + "/" +                  row.toString() + "." +                  "jpeg";        }

Chris,
I think I discovered my last issue. The ArcGIS api seems to be putting the rows in reverse order. Either top-down or bottom up, depending on the reverse of TMS. For my initial zoom level, I subtracted the row number from the total number of rows (3 rows), and my map looks good. Is there a way to find the number of rows for a given scale level?
Thanks,Scott

Subject: [Tilecache] traceback error
Message-ID: <5161afcd0912221534w3c6bc8cfhfc7dd2fb3dcf09b2@mail.gmail.com>

Hello, I'm just starting to use tilecache.  I think I have found a
bug, which I would like to discuss.  I have verified that this exists
in 2.10 and current SVN (397).  My environment is Ubuntu 9.10 with
repository-packaged python-mapscript 5.4.2 and Python 2.6.4.

I'm running tilecache this way:
./tilecache_http_server.py -t
One in 10 or 20 tiles causes the following to go to stdout, and I
don't see any consistency (might be the threads):

Traceback (most recent call last):
  File "/usr/lib/python2.6/wsgiref/handlers.py", line 93, in run
    self.result = application(self.environ, self.start_response)
  File "/home/webmap/tilecache-2.10/TileCache/Service.py", line 374, in wsgiApp
    return wsgiHandler(environ, start_response, theService)
  File "/home/webmap/tilecache-2.10/TileCache/Service.py", line 307,
in wsgiHandler
    "".join(traceback.format_tb(sys.exc_traceback)))]
AttributeError: 'module' object has no attribute 'exc_traceback'

In TileCache/Service.py, there are references to sys.exc_traceback,
which has been deprecated since Python 1.5
(http://docs.python.org/library/sys.html#sys.exc_traceback).
Following the link should make this clear.  It seems that
sys.exc_traceback and friends were *removed* in about Python 2.6, or
perhaps just in Ubuntu 9.10.  Either way, I think this is a good way
to fix the problem in a backwards-compatible way.

Subject: [Tilecache] performance ideas
Message-ID: <5161afcd0912301709y6d3a3420peb926ccf46a54af4@mail.gmail.com>

I have a few thoughts regarding performance.  I'm interested in any
input that experienced users/developers can share.  My environment is
Ubuntu 9.10

1) I notice that when TC renders a metatile, it immediately crops and
saves all subtiles within the metatile.  Has anyone considered the
idea of caching the metatile, and just cropping the requested subtile?
 I think this could improve user experience when the metasize is
something very large (I'm shooting for 20x100 or so).

2) I notice that when a metatile is rendered in mapserver (I'm using
the MS layer type), the function getBytes can take a long time when
the tilesize is large.  Is there a faster way to get the image from
mapserver?  I have tried changing the mapserver source code from
Z_BEST_COMPRESSION to Z_NO_COMPRESSION, but there is no noticeable
difference.  My imagination tells me that the "bytes" are being
organized into PNG format; is there a way to get raw bytes from MS?

3) The (sub)tiles returned from TC are larger in terms of bytes than I
think they ought to be.  For example, an empty tile is over 3000 bytes
from TC, while MS's empty tiles are well under 1000 bytes.  It looks
like PIL uses zlib, which should be sufficient.

4) Has anyone considered soft-linking empty tiles to all point to one
tile?  This would save space on the cache.  In Windows, an empty file
(0 bytes) could mean "transparent tile".  Another alternative that
would work for any Cache backend would be to manually create the
smallest possible 256x256 tile, and use that in place of the larger
PIL empty tiles.

Anyhow, these are some things that I will continue to investigate on
my own, but please share your experience with these topics if you can.

Thanks,

Jacob
