eipp: let apt make a plan, not make stuff plane

2016-06-29T10:17:41Z

Julian noticed on IRC that I fall victim to a lovely false friend by calling referring to a 'planer' all the time even through these are machines to e.g. remove splinters from woodwork ("make stuff plane"). The term I meant is written in german in this way (= with a single n) but in english there are two, aka: 'planner'. As that is unreleased code switching all instances without any transitional provisions. Also the reason why its skipped in changelog. Thanks: Julian Andres Klode Gbp-Dch: Ignore

eipp: enable xz-compressed scenario logging

2016-06-27T09:57:13Z

In 385d9f2f23057bc5808b5e013e77ba16d1c94da4 I implemented the storage of scenario files based on enabling this by default for EIPP, but I implemented it first optionally for EDSP to have it independent. The reasons mentioned in the earlier commit (debugging and bugreports) obviously apply here, especially as EIPP solutions aren't user approved, nearly impossible to verify before starting the execution and at the time of error the scenario has changed already, so that reproducing the issue becomes hard(er).

eipp: add Allow-Temporary-Remove-of-Essentials

2016-06-27T09:57:12Z

A rather special need option, but the internal planer supports this and we have a testcase for it & sometimes it is hit (as a bug through). The option itself mostly serves as a reminder for implementors that they should be careful with removes and especially temporary removes if they perform any.

eipp: implement Immediate-Configuration flag

2016-06-27T09:57:12Z

APT has 3 modes: no immediate configuration, all packages are configured immediately and its default mode of configuring essentials and pseudo-essentials immediately only. While this seems like a job of different planers at first, it might be handy to have it as an option, too, in case a planer (like apts internal one) supports different modes where the introduction of individual planers would be counter intuitive.

eipp: provide the internal planer as an external one

2016-06-27T09:57:12Z

Testing the current implementation can benefit from being able to be feed an EIPP request and produce a fully compliant response. It is also a great test for EIPP in general.

eipp: implement version 0.1 of the protocol

2016-06-27T09:43:09Z

The very first step in introducing the "external installation planer protocol" (short: EIPP) as part of my GSoC2016 project. The description reads: APT-based tools like apt-get, aptitude, synaptic, … work with the user to figure out how their system should look like after they are done installing/removing packages and their dependencies. The actual installation/removal of packages is done by dpkg with the constrain that dependencies must be fulfilled at any point in time (e.g. to run maintainer scripts). Historically APT has a super micro-management approach to this task which hasn't aged that well over the years mostly ignoring changes in dpkg and growing into an unmaintainable mess hardly anyone can debug and everyone fears to touch – especially as more and more requirements are tacked onto it like handling cycles and triggers, dealing with "important" packages first, package sources on removable media, touch minimal groups to be able to interrupt the process if needed (e.g. unattended-upgrades) which not only sky-rocket complexity but also can be mutually exclusive as you e.g. can't have minimal groups and minimal trigger executions at the same time.

factor out Pkg/DepIterator prettyprinters into own header

2016-04-28T08:08:32Z

The old prettyprinters have only access to the struct they pretty print, which isn't enough usually as we want to know for a package also a bit of state information like which version is the candidate. We therefore need to pull the DepCache into context and hence use a temporary struct which is printed instead of the iterator itself.

recheck Pre-Depends satisfaction in SmartConfigure

2016-04-13T19:33:32Z

Regression introduced in commit 590f1923121815b36ef889033c1c416a23cbe9a2 (2011!) causing apt to not check if Pre-Depends are satisfied before calling --configure. This managed to hide so perfectly well for years as Pre-Depends aren't that common, apt prefers upgrading these packages first and checks for satisfaction is already in SmartUnpack, so there is only a small window of oppertunity to break a pre-dependency relation (usually with an unpack). Verified by logchecking with two provided status files in the buglog. I would have liked to write a test, but I wasn't able to reach the needed complexity to get apt to fail – but the change is small and reasonable, so what could possible go wrong™, right?
