Other cache consumers may still find the cache file valid, even if
for others it's old. So, don't remove the file but just return None.
This way it works more like an "overlay".
Configuring cache aging makes possible to automatically throw away
old metadata, like package votes and number of downloads.
Usually, this information is still valid, from user POV, even if
quite old. But how much old? This can be tuned via enable_cache_aging()
from outside WebService class, depending on the scenario.
Scenario:
dependency = dev-lang/python
SLOT intersection = enabled
available slots = 2.6, 2.7, 3.2
installed slot = 2.7
The SLOT intersection feature worked correctly but in the end
dev-lang/python was added to the unsatisfied set because there
was a dev-lang/python-2.7 update as well. This results in other
dep calculation code to match dev-lang/python against 3.2 instead.
The SLOT intersection feature has to reduce the dependency string
scope by adding a SLOT suffix (in this case: ":2.7"). This way the
correct dependency is eventually pulled in.
Always flush stderr on a newline and also write the number of
active threads as well.
Moreover, always install the dump function at SIGQUIT when --debug
is passed.
This makes possible to have external module packages inside the
sys-kernel/ category, by just adding extra checks. In particular,
we now check against ETYPE ebuild environment variable.
This should guarantee that all the kernel sources, binaries and
headers won't be tagged by Entropy.
Everytime Repository.sync() is triggered, the last sync time
information is updated. This makes possible to figure out when
the last repository update has been run and warn user about it
if they're too old.
This makes possible to support the "readers/writers" model by
letting code to acquire Entropy Resources in shared mode (for
readers) and the same in exclusive mode (default, for writers).
In order to simplify the code and allow further improvements
(eg. the addition of readers/writers locking), migrate all the
Entropy Resources locking functions to FlockFile().
Use a semaphore to signal the worker thread if there's something to do,
otherwise the whole thread should just sleep and avoid to poll every
N seconds.
ebuild environment setup function for pkg_{prerm,postrm} can raise
OSError during os.makedirs(). Better catch it and handle the failure
nicely so that the user can take proper measures to fix it, instead
of completely bailing out with garbageish text.
It can happen that HTTP servers (or those accessed via Proxy) do not
actually provide Content-Length information in the response.
This caused UrlFetcher to keep __remotesize = 0, which means that
the same thought that the file has been fully downloaded already
under some circumstances.
As of today, both Equo and Sulfur implemented their own search
functions because the API didn't provide any direct support for
searching through all the repositories. atom_search() now offers
a basic way to do this, without reinventing the weel every time
in consumer code.
