Use pkgTagSection::Key in more places in src:apt

2022-04-01T12:16:19Z

The speed critical paths were converted earlier, but the remaining could benefit a tiny bit from this as well especially as we have the facility now available and can therefore brush up the code in various places in the process as well. Also takes the time to add the hidden Exists method advertised in the headers, but previously not implemented.

Drop support for long obsoleted Suggests alias: Optional

2022-04-01T12:16:15Z

dpkg-dev stopped recognizing it in 2007 (1.14.7) while building packages. The rename itself happened in 1995 (0.93.72).

Barbarian M-A:allowed don't satisfy :any deps of other archs

2021-09-04T13:35:15Z

What does a M-A:allowed package from non-native/non-foreign architecture provide? If we look at M-A:foreign, such a package satisfies dependencies within its own architecture, but not in other architectures, so the same should apply to :any dependencies on M-A:allowed packages, but we have a problem: While unqualified package names are architecture-specific, the virtual package name qualified with :any is not (see 3addaba1ff). We could of course make it architecture-specific now, but that would introduce many virtual packages for this relatively minor usecase and would reintroduce a need for special display handling. So, we pull a trick here: Barbarian M-A:allowed packages do not provide the architecture-independent :any package anymore, but only a specific one and every :any dependency from a barbarian package is rewritten to an or-group of the specific and the independent :any package.

Store size from volatile sources for already installed versions

2021-06-10T10:58:24Z

Volatile sources are parsed after the status file, so if we have a version already installed the size information is not stored, so that a reinstall of said version is refused claiming a broken repository. References: 1412cf51403286e9c040f9f86fd4d8306e62aff2

Include all translations when building the cache

2021-01-27T11:48:58Z

We do download all translations we ever downloaded, but we don't add all of those to the cache, meaning that if we run update with LANG=C, it might still download your de_DE translation, but it won't insert it into the cache, causing your de_DE user to not get translated messages. LP: #1907850

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.

Determine autoremovable kernels at run-time

2021-01-04T09:46:48Z

Our kernel autoremoval helper script protects the currently booted kernel, but it only runs whenever we install or remove a kernel, causing it to protect the kernel that was booted at that point in time, which is not necessarily the same kernel as the one that is running right now. Reimplement the logic in C++ such that we can calculate it at run-time: Provide a function to produce a regular expression that matches all kernels that need protecting, and by changing the default root set function in the DepCache to make use of that expression. Note that the code groups the kernels by versions as before, and then marks all kernel packages with the same version. This optimized version inserts a virtual package $kernel into the cache when building it to avoid having to iterate over all packages in the cache to find the installed ones, significantly improving performance at a minor cost when building the cache.

Add basic support for the Protected field

Do not sent our filename-provides trick to EDSP solvers

2020-06-14T08:19:39Z

If package is installed via an explicitly given deb file we store the filename as a provides, so that the frontend can request the filename and get the usual "Selected foo instead of foo.deb" message. We do not need to trouble the EDSP solvers with that though as these provides are not valid in various ways and we have already solved the link between commandline and package (and version) for them. Closes: #962741

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.
