2014-06-18remove the Section member from package structDavid Kalnischkies
A version belongs to a section and has hence a section member of its own. A package on the other hand can have multiple versions from different sections. This was "solved" by using the section which was parsed first as order of sources.list defines, but that is obviously a horribly unpredictable thing. We therefore directly remove this struct member to free some space and mark the access method as deprecated, which is told to return the section of the 'newest' known version, which is at least predictable, but possible not what it returned before – but nobody knows. Users are way better of with the Section() as returned by the version they are dealing with. It is likely the same for all versions of a package, but in the few cases it isn't, it is important (like packages moving from main/* to contrib/* or into oldlibs …).
2014-06-07do not revert candidate for protected packagesDavid Kalnischkies
In commit 21b3eac8 I promoted the check for installable dependencies to a pre-install check, which also reverts to a known good candidate (the installed version) if it fails. This revert was done even for user requested candidate switches which disabled our Broken detection so that install requests which are impossible to satisfy do not fail anymore, but print an (incomplete) solution proposal and then exit successfully. Closes: 745046

2014-03-23discard candidates via IsInstallOk to allow overrideDavid Kalnischkies
In commit 446551c8 I changed MarkInstall to discard the candidate if the candidate can't satisfy the dependency. This breaks interactive solvers like aptitude which can change the candidate on-the-fly later. In commit df77d8a5 I introduced this 'early' loop-breaking to begin with which can't be that helpful for interactive solvers as well, but makes perfect sense for non-interactives to stop them from exploring trees which can't be satisfied, but it isn't perfect as ideally we would check this before auto-installing the first dependency. This commit therefore moves the loop into its own IsInstallOk hook so that frontends can override this check if they want to and in exchange removes the loop-breaking from MarkInstall itself and does it before any dependency is installed. Closes: 740750
2014-03-23do IsInstallOk call in MarkInstall unconditionallyDavid Kalnischkies
Hooked checks could be influenced by AutoInst as a lot can happen between a call without and one with this bit set. The real cache-hit check is above this call already. Individual hooked checks can then inspect the state if they want to cache. Calling them multiple times shouldn't be a problem either way.

2014-02-06discard impossible candidates in MarkInstallDavid Kalnischkies
If a (Pre-)Depends can't be satisfied there is no point in keeping the candidate as is as it is impossible to find a solution for it, so we can just as well reset the candidate to the currently installed version. We avoid trying to install this impossible candidate later on this way. Closes: #735967

2013-10-01don't consider holds for autoremovalDavid Kalnischkies
We can't remove packages which are held back by the user with a hold, so marking them (or its dependencies) as garbage will lead our autoremover into madness – and given that the package is important enough that the user has held it back it can't be garbage (at least at the moment), so even if a front-end wants to use the info just for information display its a good idea to not consider it garbage for them. Closes: 724995
2013-08-01prefer native arch over higher priority for providersColin Watson
The rational from the buglog: > The problem here is that the Priority field in one of the Packages files > is incorrect due to a mishap with reprepro configuration, […] the > amd64 version is Priority: standard but the arm64 version is Priority: > optional (and has a stray "optional: interpreters" field). > […] > However, Priority is a rather weak property of a package because it's > typically applied via overrides, and it's easy for maintainers of > third-party repositories to misconfigure them so that overrides aren't > applied correctly. It shouldn't be ranked ahead of choosing packages > from the native architecture. In this case, I have no user-mode > emulation for arm64 set up, so choosing m4:arm64 simply won't work. This effectly makes the priority the least interesting data point in chosing a provider, which is in line with the other checks we have already order above priority in the past and also has a certain appeal by the soft irony it provides. Closes: #718482
2013-07-11prevent MarkInstall of unsynced Multi-Arch:same siblingsDavid Kalnischkies
Multi-Arch: same packages can be co-installed, but need to have the same version for all installed packages (aka "siblings"). Otherwise the unsynced versions will fight against each other and the auto-install as wel as the problem resolver will later have to decide between holding the packages or to remove one of the siblings (usually a foreign) taking a bunch of packages (like the entire foreign setup) with them. The idea here is now to be more pro-active: MarkInstall will fail for a package if the siblings aren't synced, so we don't allow a situation in which a resolver has to decide if to hold or to remove-upgrade under the assumption that the remove-upgrade decision is always wrong and doesn't deserve to be explored (expect valid out-of-syncs of course). Thats a pretty bold move to take for a library which is used by different solvers so this check is done in IsInstallOk and can be overridden if front-ends want to.

- prefer native providers over foreigns even if the chain is foreign The code preferred real over virtual packages and based on priorities.
