Add support for Phased-Update-Percentage

2021-01-08T13:48:47Z

This adds support for Phased-Update-Percentage by pinning upgrades that are not to be installed down to 1. The output of policy has been changed to add the level of phasing, and documentation has been improved to document how phased updates work. The patch detects if it is running in a chroot, and if so, always includes phased updates, restoring classic apt behavior to avoid behavioral changes on buildd chroots. Various options are added to control this all: * APT::Get::{Always,Never}-Include-Phased-Updates and their legacy update-manager equivalents to always or never include phased updates * APT::Machine-ID can be set to a UUID string to have all machines in a fleet phase the same * Dir::Etc::Machine-ID is weird in that it's default is sort of like ../machine-id, but not really, as ../machine-id would look up $PWD/../machine-id and not relative to Dir::Etc; but it allows you to override the path to machine-id (as opposed to the value) * Dir::Bin::ischroot is the path to the ischroot(1) binary which is used to detect whether we are running in a chroot.

cache: Swap locations of hashtables, hide them from non-apt users

Only expose the locations of the hasthables if APT_COMPILING_APT is set.

Add d-pointers to groups, packages, versions, and files

2020-02-25T10:44:16Z

This allows us to extend those in-cache objects with more data later on without breaking the ABI. Reserve 12 pointers for private data in the pkgCache class, and double the size of pools to 24.

Make map_pointer typesafe

2020-02-24T17:29:07Z

Instead of just using uint32_t, which would allow you to assign e.g. a map_pointer to a map_pointer, use our own smarter struct that has strict type checking. We allow creating a map_pointer from a nullptr, and we allow comparing map_pointer to nullptr, which also deals with comparisons against 0 which are often used, as 0 will be implictly converted to nullptr.

Replace map_pointer_t with map_pointer

2020-02-24T16:08:34Z

This is a first step to a type safe cache, adding typing information everywhere. Next, we'll replace map_pointer implementation with a type safe one.
