Re: [Cppcms-users] Reload views from .so

[Artyom B. <art...@ya...>]

Hello,


Two points:

1. If auto_reload is true the views would be automatically reloaded
   if the shared object had changed.

   So anything you need to do is to replace a shared object with a new one.

   This method is thread safe but has some performance penalty (it requires
   checking file timestamp each time the template is rendered)


2. You can manually load and unload shared object upon signal you get
   but this may be not thread safe so you need to make sure nothing
   happens.


   Such that if some thread renders HTML and you unload shared object
   bad things can happen.

See: http://art-blog.no-ip.info/wikipp/en/page/cppcms_1x_config#views.auto_reload


Does this fits you needs?
