** Description changed: - TEST CASE: - 1. generate a cachedb with apt-ftparchive from lucid via - apt-ftparchive --db old-db packages 2vcard_0.5-3_all.deb > Packages.1 - - use apt-ftparchive from precise and run - apt-ftparchive --db old-db packages 2vcard_0.5-3_all.deb > Packages.2 - and verify that it generates different hashes than Packages.1 (diff -u Packages.1 Packages.2) - - use apt-ftparchive from precise-proposed and run: - apt-ftparchive --db old-db packages 2vcard_0.5-3_all.deb > Packages.3 - and verify that the hashes are identical to the ones in Packages.1 + [Impact] The archive.ubuntu.com master server has just been upgraded from lucid - to precise. As a result, the apt version went from 0.7.25.3 to + to precise. As a result, the apt version went from 0.7.25.3 to 0.8.16~exp12, and apparently some time in that interval the on-disk format of apt-ftparchive's cache changed. This wouldn't be a problem, except apt-ftparchive itself doesn't *notice* that the cache format has changed, and instead happily reads the existing files and parses them incorrectly, resulting in corrupted checksums output in the Packages file for each of the .debs. apt-ftparchive should version its file formats so that it correctly notices incompatible cache files. + + [Test Case] + + * generate a cachedb with apt-ftparchive from lucid via + apt-ftparchive --db old-db packages 2vcard_0.5-3_all.deb > Packages.1 + + * use apt-ftparchive from precise and run + apt-ftparchive --db old-db packages 2vcard_0.5-3_all.deb > Packages.2 + and verify that it generates different hashes than Packages.1 + (diff -u Packages.1 Packages.2) + + * use apt-ftparchive from precise-proposed and run: + apt-ftparchive --db old-db packages 2vcard_0.5-3_all.deb > Packages.3 + and verify that the hashes are identical to the ones in Packages.1
