ABI BREAK: Implement pinning by source package See merge request apt-team/apt!96

Revert "Add a Packages-Require-Authorization Release file field"

2020-02-16T11:46:09Z

This experiment did not turn out sensibly, as some servers do not accept credentials when none are expected and fail, so you cannot mirror such a repository. This reverts commit c2b9b0489538fed4770515bd8853a960b13a2618.

policy: Add SetPriority() methods

2020-02-16T10:46:29Z

These allow overriding priorities, however, pins set by SetPriority for package files will be overriden by calls to InitDefaults().

policy: Implement pinning by source package

2020-01-17T12:24:39Z

This implements the src: syntax inside policy, allowing you to pin by source package. This by default only pins the native architecuture, use src:pkg:any to pin for all architectures in your cache. Closes: #166032

policy: Get rid of Pins array

policy: Remove GetMatch and GetPriority(pkgIterator)

2019-06-14T13:45:28Z

These functions do not produce any useful results anymore, so it's pointless to keep them around.

Add a Packages-Require-Authorization Release file field

2019-02-01T16:52:03Z

This new field allows a repository to declare that access to packages requires authorization. The current implementation will set the pin to -32768 if no authorization has been provided in the auth.conf(.d) files. This implementation is suboptimal in two aspects: (1) A repository should behave more like NotSource repositories (2) We only have the host name for the repository, we cannot use paths yet. - We can fix those after an ABI break. The code also adds a check to acquire-item.cc to not use the specified repository as a download source, mimicking NotSource.

Introduce experimental 'never' pinning for sources

2019-02-01T16:51:35Z

This allows disabling a repository by pinning it to 'never', which is internally translated to a value of -32768 (or whatever the minimum of short is). This overrides any other pin for that repository. It can be used to make sure certain sources are never used; for example, in unattended-upgrades. To prevent semantic changes to existing files, we substitute min + 1 for every pin-priority: . This is a temporary solution, as we are waiting for an ABI break. To add pins with that value, the special Pin-Priority "never" may be used for now. It's unclear if that will persist, or if the interface will change eventually.

show warnings instead of errors if files are unreadable

2017-07-26T17:09:04Z

We used to fail on unreadable config/preferences/sources files, but at least for sources we didn't in the past and it seems harsh to refuse to work because of a single file, especially as the error messages are inconsistent and end up being silly (like suggesting to run apt update to fix the problem…).
