I guess the main goal is to avoid that the adopt of python on server could slow it. Infact , the main difference from a desktop and a server is that the first is serving only one perosn and this mean that the user could wait also for a work for himself. Instead a server is used from many users and

Hi Poalo, How you can say that the overhead should be minimal. ? :)) However surely best ifthe python on server is optional in compiling. So if an user dont want it should remove it. A. 2014-08-29 11:45 GMT+02:00 Paolo Cavallini : > Il 29/08/2014 11:41, Andrea Peri ha scritto: >> I guess the m

Re: [Qgis-developer] QEP: QGIS Mapserver Python Plugins

A quick question: python plugins only add an #include and two lines of code in qgis_map_serv.cpp, a #ifdef SERVERPLUGINS block should be enough to disable them completely, where should I add that option to let cmake know about it? You can make an entries in CMakeLists.txt and in cmake_templates

Another question. Is about the security of the environment. I don't know too well the possibility of python in a qgis project. But I fear that a qgis project could have some python code to start ad startup of the qgis project. This mean that the same code should be run in the server when it start
