  • Ticket #36 – Description

    initial v1  
    11Hello, 
    22   Sorry to ask a stupid question, but, is PyYaml thread-safe ? I am trying to run PyYaml under WebWare and I get a session identifier. Due to the nature of WebWare being servlet based, I find that it sometimes calls 'get session' more than once during the lifetime of processing the servlet. The code that get's run more than once is;

    56        if debug: 
    … …  
    2526            self._lock.release() 
    2627        return item 
    27  
     28}}} 
    2829    When I put wrapper print statements around the yaml.load, I notice that the first time it works without fail, the next time I get this;

    6567  So, from my total layman's perspective, it appears that the __init__.py is expected to be called 'once', yet due to WebWare's threading, I think it get's called more than once. Either way, I could be totally and whole heartedly wrong, any ideas ?
