2014-10-07use _apt:root only for partial directoriesDavid Kalnischkies
Using a different user for calling methods is intended to protect us from methods running amok (via remotely exploited bugs) by limiting what can be done by them. By using root:root for the final directories and just have the files in partial writeable by the methods we enhance this in sofar as a method can't modify already verified data in its parent directory anymore. As a side effect, this also clears most of the problems you could have if the final directories are shared without user-sharing or if these directories disappear as they are now again root owned and only the partial directories contain _apt owned files (usually none if apt isn't running) and the directory itself is autocreated with the right permissions.
2014-10-07ensure partial dirs are 0700 and owned by _apt:rootDavid Kalnischkies
Reworks the API involved in creating and setting up the fetcher to be a bit more pleasent to look at and work with as e.g. an empty string for no lock isn't very nice. With the lock we can also stop creating all our partial directories "just in case". This way we can also be a bit more aggressive with the partial directory itself as with a lock, we know we will gone need it.

2014-10-01Use Acquire::Allow{InsecureRepositories,DowngradeToInsecureRepositories}Michael Vogt
The configuration key Acquire::AllowInsecureRepositories controls if apt allows loading of unsigned repositories at all. The configuration Acquire::AllowDowngradeToInsecureRepositories controls if a signed repository can ever become unsigned. This should really never be needed but we provide it to avoid having to mess around in /var/lib/apt/lists if there is a use-case for this (which I can't think of right now).

2014-09-28replace c-string Mode with c++-string ActiveSubprocessDavid Kalnischkies
A long-lasting FIXME in the acquire code points out the problem that we e.g. for decompressors assign c-string representations of c++-strings to the Mode variable, which e.g. cppcheck points out as very bad. In practice, nothing major happens as the c++-strings do not run out of scope until Mode would do, but that is bad style and fragile, so the obvious proper fix is to use a c++ string for storage to begin with. The slight complications stems from the fact that progress reporting code in frontends potentially uses Mode and compares it with NULL, which can't be done with std::string, so instead of just changing the type we introduce a new variable and deprecate the old one.

2014-09-28allow options between command and -- on commandlineDavid Kalnischkies

2014-09-27allow fetcher setup without directory creationDavid Kalnischkies
apt-get download and changelog as well as apt-helper reuse the acquire system for their own proposes without requiring the directories the fetcher wants to create, which is a problem if you run them as non-root and the directories do not exist as it greets you with: E: Archives directory /var/cache/apt/archives/partial is missing. - Acquire (13: Permission denied) Closes: 762898
2014-09-27store source name and version in binary cacheDavid Kalnischkies
Accessing the package records to acquire this information is pretty costly, so that information wasn't used so far in many places. The most noticeable user by far is EDSP at the moment, but there are ideas to change that which this commit tries to enable.

2014-09-27add and use 'apt-key verify' which prefers gpgv over gpgDavid Kalnischkies
gnupg/gnupg2 can do verify just fine of course, so we don't need to use gpgv here, but it is what we always used in the past, so there might be scripts expecting a certain output and more importantly the output of apt-cdrom contains messages from gpg and even with all the settings we activate to prevent it, it still shows (in some versions) a quiet scary: "gpg: WARNING: Using untrusted key!" message. Keeping the use of gpgv is the simplest way to prevent it. We are increasing also the "Breaks: apt" version from libapt as it requires a newer apt-key than might be installed in partial upgrades.
2014-09-27add --readonly option for apt-key advDavid Kalnischkies
Some advanced commands can be executed without the keyring being modified like --verify, so this adds an option to disable the mergeback and uses it for our gpg calling code. Git-Dch: Ignore
2014-09-27use apt-key adv (+ gnupg) instead of gpgv for verifyDavid Kalnischkies
apt-key does the keyring merge as we need it, so we just call it instead of reimplementing it to do the merging before gpgv. This means we don't use gpgv anymore (we never depended on it explicitly - bad style), but it also means that the message in apt-cdrom add is a bit less friendly as it says loudly "untrusted key", but for a one-time command its okay.

2014-09-27add an API for cache filters/matcherDavid Kalnischkies
A lot of code deals with iterating over packages and checking for specific states. At the moment these are all handcrafted inplace, but that makes sharing common code which just differs in the states it checks rather difficult and is error prune. Having an API to construct arbitrary complex filters will come in handy for those. Git-Dch: Ignore
2014-09-27move PCI::From* methods into CacheSetHelper classDavid Kalnischkies
The methods itself deal with the helper a lot, so it makes sense to move them to the helper itself, which helps also if we want to override some of these methods, the FromString mentioned in the bugreport being the obvious example. VCI is spared from this change for now as while it would fit with the same reasoning it much heavier entangled with the previous CacheSetHelper change, so moving it now would mean breaking the API. The PCI change is worthwhile on its own though as it is used by VCI. Closes: 686221
2014-09-27rework cachesets API to allow future extensionDavid Kalnischkies
The introduction of Fnmatch showed that each new selector would require multiple new virtual methods in the CacheSetHelper to work correctly, which isn't that great. We now flip to a single virtual method which handles all cases separated by an enum – as new enum values can be added without an ABI break. Great care was taken to make old code work with the new way of organisation, which means in return that you might be bombarded with deprecation warnings now if you don't adapt, but code should still compile and work as before as can be seen in apt itself with this commit.

2014-09-27fix progress output for (dist-)upgrade calculationDavid Kalnischkies
Previously, we had a start and a done of the calculation printed by higher-level code, but this got intermixed by progress reporting from an external solver or the output of autoremove code… The higherlevel code is now only responsible for instantiating a progress object of its choosing (if it wants progress after all) and the rest will be handled by the upgrade code. Either it is used to show the progress of the external solver or the internal solver will give some hints about its overall progress. The later isn't really a proper progress as it will jump forward after each substep, but that is at least a bit better than before without any progress indication. Fixes also the 'strange' non-display of this progress line in -q=1, while all others are shown, which is reflected by all testcase changes.
2014-09-27de-duplicate version strings in the cacheDavid Kalnischkies
Turns out that version numbers aren't as random as you might guess. In my cache for example, I have: Total package names: 69513 (1390 k) Total package structures: 188259 (9036 k) Total distinct versions: 186345 (13.4 M) Total dependencies: 2052242 (57.5 M) which amounts to 1035873 (10,1 M) strings. Reusing version strings reduces this to 161465 (3.479 k). This comes at a cost of course: Generation is slightly slower, but we are still faster than what we started with and it makes room (also cache size wise) for further changes.
