[Qgis-developer] QgisMapserver - need to restart Apache on every project file change ?
Hi all, Marco, I am testing Qgis mapserver on a demo server. I realized I needed to restart Apache so that an server side project file has been modified to see the changes in the WMS. Is it "normal", or is it a misconfiguration on my side ? NB : I am using ubuntu 10.10, and symbolic links to add any qgis project + data as a new server. Thanks in advance, Kimaidou ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] QgisMapserver - need to restart Apache on every project file change ?
Hi, You need to reload, not restart Apache. A restart is not necessary. This is due to the caching mechanism QGIS server uses. This is suboptimal and will be improved in a future version, most likely in late spring. There will be a command to reload only one specific project without having to reload Apache.

Hi Andreas Thanks for your prompt answer ! I will reload Apache configuration instead. cheers Kimaidou 2011/4/4 Andreas Neumann > Hi, > > You need to reload, not restart Apache.

You can run QGIS Mapserver as CGI instead of FastCGI. Then it reloads on every request. On Ubuntu, the only thing you have to do is cd /usr/lib/cgi-bin/ && sudo ln -s mapserv.fcgi qgis_mapserv.cgi Pirmin -- Pirmin Kalberer Sourcepole - Linux & Open Source Solutions http://www.sourcepole.com ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] QgisMapserver - need to restart Apache on every project file change ?
Yes - but it comes at a price: the CGI version does not profit from the caching mechanism and thus will be a lot slower. Also, it has to load QGIS server and libraries for each request. For medium complex to complex projects this will be way too slow. Andreas On Mon, 4 Apr 2011 13:09:23 +0200, Pirmin Kalberer wrote: Hi Kimaidou, Am Montag, 4.

Thanks Pirmin and Andreas, Now I have 2 different ways I can use according to specific needs.

I haven't found the time to setup a fresher qgismapserver, but looking at the source code in trunk I can't see what's causing this. It seems that, inside the fcgi loop, a configuration for a requested MAP confipath is searched inside the cache instance. In case it's found the result is directly returned, otherwise a new cache entry is created and returned. I would expect this should work, but before I will build the trunk version I would like to know if it's solved indeed. thanks, Giovanni ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] QgisMapserver - need to restart Apache on every project file change ?
Hi Giovanni QGIS server uses the QFileSystemWatcher class ( http://doc.qt.nokia.com/4.7/qfilesystemwatcher.html) to check if a configuration file has changed. So in newer versions, changes to the published project files should be picked up without restarting apache. Regards, Marco Am Dienstag, 18. Oktober 2011, 19.23:28 schrieb G.

Re: [Qgis-developer] QgisMapserver - need to restart Apache on every project file change ?
Thanks Marco, I supposed it watching the source code. But what about the need to reload apache if I send a different MAP request (i.e. a differnet configuration file)? It should work too, am I wrong? giovanni 2011/10/19 Marco Hugentobler > Hi Giovanni > > QGIS server uses the QFileSystemWatcher class ( > http://doc.qt.nokia.com/4.7/qfilesystemwatcher.html) to check if a > configuration > file has changed.
