Re: [mapserver-users] mapserver defunct

2011-01-11 Thread Stephen Woodbridge


Wim,

I'm not sure I have any magic bullet for this problem, because I'm not 
sure what is causing it. If this was my project, I would tackle it like 
this:


1. alert people we have a problem that might impact the release date if 
you have not already done that

2. divide the problem to try and localize what is causing it

a. do the tiles that fail, always fail? this points at a potential 
mapserver related issue as opposed to a load issue

a.1 have you turned on mapfile DEBUG output? can you identify the layer
a.2 you can get some maybe useful output from:

strace /path/to/mapserv QUERY_STRING=''

gdb /path/to/mapserv
run QUERY_STRING=''
where
quit

valgrind /path/to/mapserv QUERY_STRING=''

a.3 you can run it with shp2img ...

b. is it fastcgi, do you see the same problem if you build it as cgi
c. is it lighttpd, do you see the same problem if you run it with apache 
fastcgi? what about apache cgi?


Intermittent problems are the hardest to diagnose because they often are 
not reproducable in a debuging environment. We might be able to help you 
with more information.


I have done a lot of load testing on various versions of mapserver and 
tiled all of US and Canada about 4-5 different times using mapserver. I 
have not used FastCGI/Lighty and lighttpd, so I'm not sure about what 
influence that might have on the problem.


Hope this gives you some ideas.

I'm sure there are others. So since you are running fastcgi, it is
the responsibility of the fastcgi parent process to clean up dead
child processes. It is likely that it is busy because you are doing
load testing or there is some subtle issue that is occurring. If you
are getting good responses from mapserver, you probably do not need
to worry about it unless you are getting tons of them.

If you are using apache, I believe there is a parameter that you can
set for fastcgi processes which will let them die after N requests.
This should clean those up and apache will spawn a new process if
needed to replace the that died.

[mapserver-users] opacity and mode=legend

2011-01-11 Thread Steve . Toutant

Hi,
I'm using mode=legend and in my template I'm trying to get the OPACITY 
value in the layer definition.
I tried this [if name=layer_opacity oper=isset]75[/if];
that returns nothing. 

is it possible to verify if the OPACITY is set for a layer? If yes, how to 
get the value?
thanks

[mapserver-users] keyimage size and url

2011-01-11 Thread Steve . Toutant

Hi,
In my mapfile I have a layer defined as a external WMS layer 
(CONNECTIONTYPE WMS, .)

I use KEYIMAGE to set the icon in my geoext legend.
For a layer the legend is complex and the icon is very small. is it 
possible to change the size of a KEYIMAGE?

Also, is it possible to use a getLegendGraphic request to get the legend 
icon instead of using KEYIMAGE (it seems that we cannot provide a url with 
KEYIMAGE)?

Does KEYIMAGE is the appropriate solution?
thanks for your help,

Re: [mapserver-users] How would I modify a map file so that whena getcapabilities is run it outputs as tiled layers (wms-t) includinglisting resolutions listed below:

2011-01-11 Thread Rahkonen Jukka

Hi,

Just guessing, but sending resolutions with GetCapabilities could make sense 
for example with a client like uDig which can cache WMS-C tiles locally.  The 
WMS calls uDig sends in this case are just plain WMS requests and Mapserver 
would handle them nicely. Perhaps John would like to do something similar.

One alternatively might be to use a local, edited GetCapabilities document 
instead of letting Mapserver to create it on-the-fly.

Hi,

  Not sure I understand well the question: Mapserver does not support 
tiled layers by itself. Usually when doing tiles, you will use tilecache 
servers (tilecache.org, or mode-geocache 
http://code.google.com/p/mod-geocache/  ) that can be set up to

  Wehn you mention getcapabilities, are referring to the getcapabilities 
support in the WMTS (web map tiling service from OGC)? If that is the 
case, I would recommend again to  check the tilecache libraries 
mentioned above.
If this does not reflect what you intend to accomplish, please give more 
details on what you expect from MapServer.

Re: [mapserver-users] Labels are cut at the borders of the tiles

2011-01-11 Thread Wim Vanbelle

Thanks for clearing that out Thomas. We were having similar issues here.

Is there a similar setting for linestring drawing? Eg when using pixel
offset the lines get cut off at the end of the tiles.

This is resolved using the gutter parameter in openlayers as  you have
mentioned, but is still a problem for google and bing maps.

thanks.
