Package: libept-dev
Version: 0.5.10+b1
Severity: wishlist
Hello,
When outside of libept the Apt database is changed (for example, after
an apt-get update), the currently opened Apt silently object becomes
invalid.
A possible idea to work around this is to obtain access to the Apt
object through an AptSession object, which sits in the stack with RAII
semantics. Every time AptSession is instantiated, it checks if the
timestamp of the Apt database is changed, and if so it reopens the Apt
cache before giving access to the Apt object.
Ciao,
Enrico

Version: 0.5.15
Hello,
in 0.5.15 I've implemented Apt::checkCacheUpdates, that can be called to
reopen the cache if it has changed.
The idea is that you call apt.checkCacheUpdates() before starting a
sequence of apt operations, and hope that the apt cache isn't changed
exactly during that sequence. But at least, the likelyhood of that is
low.
Unfortunately, there's no way to completely prevent this without being
root, as the apt cache doesn't support read locking.
Ciao,
Enrico
