b26842e826 [entropy.db] direct: wrap yield around a try/finally block 2013-12-07 20:30:06 +01:00
Fabio Erculiani
c356d615f3 [Rigo] use direct access to the installed packages repository, avoid locking 
Locking is too expensive, and using memory cached data may result
in huge inconsistencies due to stale data. Direct mode allows to
skip memory cache and read data directly from the database storage.
However, entropy.db.sqlite queries using memory caches did not
perform very well when cache is cold. But this has been solved by
directed() already (a different query is run if memory cache is disabled).

3545f2b619 [entropy.db] add direct access support to repository 
In latency sensitive code paths, the performance penality caused
by file lock contention and memory cache invalidation is too high.
This problem happens in Rigo, which is extremely latency sensitive.
Since we don't want to crap on the user, a way to solve this is
letting API consumers skip the memory cache and read data directly
from the database store. The trade off is that data may be stale,
incomplete, or invalid, but as long as the consumer is aware of this,
that's fine.

1739953f8d [Rigo] add installed pkgs repository wherever it makes sense 
In latency sensitive code paths, it's much better to deal with
stale and invalid data rather than causing long delays.

a8c98a5081 [entropy.client.package.actions] action: cope with unavailability of file locking 
Some filesystems, especially old network file systems, don't support
file locking. Try not to explode if this is the case but rather nag
the user with scary error messages.
