Re: Beaker error (Beaker 1.4.2 released)
Hi Ben, I've been running beaker with your patch for over a week now on our live site and have seen no further messages, even under load. I'd say the problem is fixed. Thank you!

Re: Beaker error (Beaker 1.4.2 released)
Hi Ben, I've recently upgraded one of my busiest sites to use beaker 1.4.2 and I am getting an intermittent error: Module beaker.cache:115 in get def get(self, key, **kw): Retrieve a cached value from the container return self._get_value(key, **kw).get_value() get_value = get return self._get_value(key, **kw).get_value() Module beaker.container:269 in get_value if not creation_lock.acquire(wait=False): debug(get_value returning old value while new one is created) return value else: debug(lock_creatfunc (didnt wait)) return value UnboundLocalError: local variable 'value' referenced before assignment I am using Memcached with the pure-python driver as the caching backend. What we do is manually invalidate (delete) the cache under certain circumstances. What is happening here as far as I can tell is: - the cache gets delted (using memcached's delete key functionality) - the first request comes in where it gets regenerated - while the cache is being regenerated, a second request comes in and beaker tries to return the old value which no longer exists, even though for some reason beaker thinks its there. I understand this is to avoid the dog-pile effect, and would be the correct thing to do if we still had the old cache. Is delting the key not the way to go? Can I 'invlidate' the cache some other way that preserves the anti-dogpile effect? Also, should beaker not behave differently if there is no old value to return? Thanks, Damian This bug has been fixed with a work-around in Beaker, and Beaker 1.4.2 has been released with it. - Ben --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

One issue in Beaker is there are two SQLAlchemy backends in the code but only one of them works. I think it's the one that's not in the documentation, but I've deleted my INI file already so I'm not sure which one worked. -- Mike Orr sluggos...@gmail.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Is there a way to get the session ID if a session has been established for this request, or None if not? Because another problem I'm having is that certain requests (all related to RoboHelp static files, which are served by paste.fileapp and requested by RoboHelp's Javascript) are being logged with a different session ID for every hit, which ruins the aggregate session count. One site contains only RoboHelp files and is doing this throughout. Another site uses RoboHelp only for its help section, and the problem seems to be isolated to that section. So I could blame the browser or Javascript, but isn't Beaker generating the session ID? What criteria does it use to determine whether to generate a new ID? Would it be typical for Javascript requests to not send the session cookie, or does the browser just send them automatically? -- Mike Orr sluggos...@gmail.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.
