Public bug reported: [Impact] The apt.Package objects use the id as the hash, but the hash can change after reopening, meaning that code will fail to work, for example:
c=apt.Cache() p=c["a"] set_of_p={p} c.open() assert p in set_of_p will fail. [Test case] The above test case is run as part of autopkgtest (syntax is slightly different) [Regression potential] Hashing packages objects will be slower as it hashes the name and architecture now. ** Affects: python-apt (Ubuntu) Importance: Undecided Status: New ** Affects: python-apt (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: python-apt (Ubuntu Bionic) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python-apt in Ubuntu. https://bugs.launchpad.net/bugs/1780099 Title: Cache remapping breaks hashing of Package objects Status in python-apt package in Ubuntu: New Status in python-apt source package in Bionic: New Bug description: [Impact] The apt.Package objects use the id as the hash, but the hash can change after reopening, meaning that code will fail to work, for example: c=apt.Cache() p=c["a"] set_of_p={p} c.open() assert p in set_of_p will fail.
