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. Allegri: 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 -- Dr. Marco Hugentobler Sourcepole - Linux Open Source Solutions Churerstrasse 22, CH-8808 Pfäffikon SZ, Switzerland marco.hugentob...@sourcepole.ch http://www.sourcepole.ch Technical Advisor QGIS Project Steering Committee ___ 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 ?
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 marco.hugentob...@sourcepole.ch 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.

Hi Giovanni It should work too, am I wrong? Yes, the MAP parameter should be considered too. Regards, Marco Am Mittwoch, 19. Oktober 2011, 09.30:02 schrieb G.

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.
