2014-06-18do not call resolver twice on (dist-)upgradeDavid Kalnischkies
2014-06-18fix SubstVar to be usable as a replace_all methodDavid Kalnischkies
The name suggests that it is supposed to substitute a variable with a value, but we tend to use it in a more liberal replace_all() fashion, but this breaks if either of the parameters is empty or more importantly if two "variable" occurrences follow each other directly.
2014-06-18don't send pkg from an unknown architecture via EDSPDavid Kalnischkies
APT's cache can include packages from architectures dpkg has no knowledge about and can therefore not be installed for e.g. to allow easy lookups. There is no point in telling external solvers about them though and some of them might even be really talkative about ignoring them if we do.

2014-06-18[API-Break] rename pkgCache::Package::NextPackage to pkgCache::Package::NextMichael Vogt
This is a internal struct not a external interface so the actual breakage should be small.

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.

2014-05-30without a filename we can't stat pipesDavid Kalnischkies
EDSP code uses pipes opened via an FD as sources and later for those files modification times and filesize are read - but never really used again. The result we get from FileFd is probably wrong, but as we don't use it anyway, we just don't fallback if we have nothing to fallback to Git-Dch: Ignore
2014-05-30check exit status of external solversDavid Kalnischkies
Solvers are supposed to exit successfully even if they haven't found a solution, but a solver which fails drastically (like e.g. segfaults) should be detected and dealt with accordingly instead of ignored.

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).

2014-05-22Add APT::Acquire::$(host)::By-Hash=1 knob, add Acquire-By-Hash to Release fileMichael Vogt
The by-hash can be configured on a per-hostname basis and a Release file can indicate that it has by-hash support via a new flag. The location of the hash now matches the AptByHash spec
2014-05-22add TODOMichael Vogt
2014-05-22Implement simple by-hash for apt updateMichael Vogt
This implements a apt update schema that get the indexfiles by the hash instead of the name. The rational is that updates to the archive servers/mirrors are not atomic so the client may have the previous version of the Release file when the server updates to a new Release file and new Packages/Sources/Translations indexes. By keeping the files around by their hash we can still get the previous indexfile without a hashsum mismatch. Enable with APT::Acquire::By-Hash=1
2014-05-15Never parse Version/Architecture tags in a Translation-$lang fileMichael Vogt
Version/Architecture information in a Translation-$lang file is not allowed, so don't try to parse it. This is a fix for a bugreport where a Translation-en file contained the content of the regular Packages file (probably due to local FS corruption). This lead to strange error messages on file download. Thanks to Thomas Reusch for the report.

If one of the pkgAcqIndex{,Merge}Diffs fails, they will run pkgAcqIndex() which needs the IndexTarget/indexRecords data. So we pass it along.
2014-05-10invalid cache if architecture set doesn't matchDavid Kalnischkies
The cache heavily depends on the architecture(s) it is build for, especially if you move from single- to multiarch. Adding a new architecture to dpkg therefore has to be detected and must invalidate the cache so that we don't operate on incorrect data. The incorrect data will prevent us from doing otherwise sensible actions (it doesn't allow bad things to happen) and the recovery is simple and automatic in most cases, so this hides pretty well and is also not as serious as it might sound at first. Closes: 745036
2014-05-10improve pkgTagSection scanning and parsingDavid Kalnischkies
Removes the 256 fields limit, deals consistently with spaces littered all over the place and is even a tiny bit faster than before. Even comes with a bunch of new tests to validate these claims.
2014-05-09parse and retrieve multiple Descriptions in one recordDavid Kalnischkies
It seems unlikely for now that proper archives will carry multiple Description-* stanzas in the Packages (or Translation-*) file, but sometimes apt eats its own output as shown by the usage of the CD team and it would be interesting to let apt output multiple translations e.g. in 'apt-cache show'.
2014-05-09tell download methods the expected hashesDavid Kalnischkies
Now that we have all hashes in the acquire system, pass the info down to the methods, so that it can use it in the request and/or to precheck the response.
2014-05-09promote ExpectedHashes to a pkgAcquire::Item memberDavid Kalnischkies
Beside being another big API break with hopefully zero fallout in reality it avoids having the same member and helper code in each and every subclass.
2014-05-09use HashStringList in the acquire systemDavid Kalnischkies
It is not very extensible to have the supported Hashes hardcoded everywhere and especially if it is part of virtual method names. It is also possible that a method does not support the 'best' hash (yet), so we might end up not being able to verify a file even though we have a common subset of supported hashes. And those are just two of the cases in which it is handy to have a more dynamic selection. The downside is that this is a MAJOR API break, but the HashStringList has a string constructor for compatibility, so with a bit of luck the few frontends playing with the acquire system directly are okay.
2014-05-09use 'best' hash for source authenticationDavid Kalnischkies
Collect all hashes we can get from the source record and put them into a HashStringList so that 'apt-get source' can use it instead of using always the MD5sum. We therefore also deprecate the MD5 struct member in favor of the list. While at it, the parsing of the Files is enhanced so that records which miss "Files" (aka MD5 checksums) are still searched for other checksums as they include just as much data, just not with a nice and catchy name. LP: 1098738
2014-05-09add a simple container for HashStringsDavid Kalnischkies
APT supports more than just one HashString and even allows to enforce the usage of a specific hash. This class is intended to help with storage and passing around of the HashStrings. Git-Dch: Ignore
