** Description changed: - When using an https: connection, apt-get does not properly reuse - connections. Because https setup costs can be quite high, this can cause - much slowdown when, for example, many different distributions on the - same server need to be checked. + [Impact] + + * Apt does not re-use https connections. This results in a significant + performance hit. + + * Additionally the hosts of mirrors are experiencing unnecessarily high + load due to this + + [Test Case] + + * Run apt-get -update using https connections. It will be noticably slower in comparison to + after this change + + [Regression Potential] + + * This fixes apt, by changing the way it uses curl, such that only + problematic error codes cause failure. + + * Might result in zero length files, or updates not being downloaded. + + * https connections hanging in the event that the above logic does not + correctly handle error cases. + + [Other Info] + * This is already in Saucy. + + * This is not imperative to be pulled into precise, but it would be nice. + + * This is really more of an enhancement than a bug fix. + + * I have been using this patch for over 5 months now with no negative + side affects. + + * I have been told that this patch has been deployed in a large (multi- + thousand install base) organization with no negative side affects as + well. + + + + + + When using an https: connection, apt-get does not properly reuse connections. Because https setup costs can be quite high, this can cause much slowdown when, for example, many different distributions on the same server need to be checked. I believe the attached patch addresses the difficulty.
