2015-09-14avoid using global PendingError to avoid failing too often too soonDavid Kalnischkies
Our error reporting is historically grown into some kind of mess. A while ago I implemented stacking for the global error which is used in this commit now to wrap calls to functions which do not report (all) errors via return, so that only failures in those calls cause a failure to propergate down the chain rather than failing if anything (potentially totally unrelated) has failed at some point in the past. This way we can avoid stopping the entire acquire process just because a single source produced an error for example. It also means that after the acquire process the cache is generated – even if the acquire process had failures – as we still have the old good data around we can and should generate a cache for (again). There are probably more instances of this hiding, but all these looked like the easiest to work with and fix with reasonable (aka net-positive) effects.
2015-08-27just-in-time removal of broken essential packagesDavid Kalnischkies
We deal with Conflicts in SmartUnpack in pretty much the same way, but Breaks weren't handled in SmartConfigure so that the remove was sheduled after the configuration of the package breaking the to-be-removed. Closes: 796070

2015-08-10remove the compatibility markers for 4.13 abiDavid Kalnischkies
We aren't and we will not be really compatible again with the previous stable abi, so lets drop these markers (which never made it into a released version) for good as they have outlived their intend already. Git-Dch: Ignore
2015-08-10make all d-pointer * const pointersDavid Kalnischkies
Doing this disables the implicit copy assignment operator (among others) which would cause hovac if used on the classes as it would just copy the pointer, not the data the d-pointer points to. For most of the classes we don't need a copy assignment operator anyway and in many classes it was broken before as many contain a pointer of some sort. Only for our Cacheset Container interfaces we define an explicit copy assignment operator which could later be implemented to copy the data from one d-pointer to the other if we need it.

2014-12-07properly handle already reinstall pkgs in orderingDavid Kalnischkies
The bugreport itself describes the case of the ordering code detecting a loop where none is present, but the testcase finds also cases in which there is actually a loop and we fail to realize it. --reinstall can be considered an interactive command through and it usually doesn't encounter such "hard" problems (= looping essentials), so this is less serious than it sounds at first. Closes: 770291

2014-07-29Fix SmartConfigure to ignore ordering of packages that are already validMichael Vogt
With the change of SmartConfigure() in git commit 42d51f the ordering code was trying to re-order dependencies, even when at this point in time this was not needed. Now it will first check all targets of the given dependency and only if there is not a good one try to reorder and unpack/configure as needed. Closes: LP: #1347721

2014-05-22fix tight loop detection and temporary removesDavid Kalnischkies
As outlined in #748355 apt segfaulted if it encountered a loop between a package pre-depending on a package conflicting with the previous as it ended up in an endless loop trying to unpack 'the other package'. In this specific case as an essential package is involved a lot of force needs to be applied, but can also be caused by 'normal' tight loops and highlights a problem in how we handle breaks which we want to avoid. The fix comes in multiple entangled changes: 1. All Smart* calls are guarded with loop detection. Some already had it, some had parts of it, some did it incorrect, and some didn't even try. 2. temporary removes to avoid a loop (which is done if a loop is detected) prevent the unpack of this looping package (we tried to unpack it to avoid the conflict/breaks, but due to a loop we couldn't, so we remove/deconfigure it instead which means we can't unpack it now) 3. handle conflicts and breaks very similar instead of duplicating most of the code. The only remaining difference is, as it should: deconfigure is enough for breaks, for conflicts we need the big hammer
2014-05-22consistently fail if Smart* packagemanager actions failDavid Kalnischkies
These failure conditions come with an error message attached and the conditions aren't workaroundable (otherwise this would have been done instead of returning failure), so not erroring out here means that we execute dpkg later on with a known not-working ordering adding insult (our own error messages at the end) to injury (dpkg failure).

2014-03-13do not configure already unpacked packages needlesslyDavid Kalnischkies
The unpack of a M-A:same package will force the unpack of all its siblings directly to prevent that they could be separated by later immediate actions. In commit 634985f8 a call to SmartConfigure was introduced to configure these packages at the time the installation order encounters them. Usually, the unpack order is already okay, so that this 'earlier' unpack was not needed and if it wouldn't have been done, the package would now only be unpacked, but by configuring the package now we impose new requirements which must be satisfied. The code is clever enough to handle this most of the time (it worked for 2 years!), but it isn't needed and in very coupled cases this can fail. Removing this call again removes this extra burden and so simplifies the ordering as can be seen in the modified tests. Famous last words, but I don't see a reason for this extra burden to exist hence the remove. Closes: 740843

fixup for 42d51f333e8ef522fed02cdfc48663488d56c3a3 The for-loop iterating over the DepIterators which need configuration can (and will be in 'complicated' situations) run multiple times, so we can't just GlobOr on the DepIterator as it modifies it, so that the next iteration over the list ends up checking another dependency leading us into a 'Internal error, packages left unconfigured. foopkg' maybe or we are 'lucky' and calculate a solution which might break down the line Git-Dch: Ignore
2013-06-09do unpacks before configures in SmartConfigureDavid Kalnischkies
Splits the big loop over dependencies in SmartConfigure which unpacks and configures dependencies into two loops and reverse their order, so that all dependencies which need to be unpacked are handled first and only after that configures are issued for dependencies. This is needed as otherwise the unpack of a (new) dependency will be issued in between a configure call for two (or more) packages which form a loop, which means the configure calls aren't part of the same dpkg call and therefore dpkg bails out. Such tight loops should really be avoided as they are usually wrong – and in reality the dependencies in libreoffice were greatly simplified thanks to Rene Engelhard so the problem is gone for the benefit of all.
