2015-08-29implement indextargets option 'DefaultEnabled'David Kalnischkies
Some targets like Contents-udeb are special-needs targets. Shipping the configuration snippet for them is okay, but they shouldn't be downloaded by default. Forcing the user to enable targets by uncommenting targets is wrong and this would still not really solve the problem completely as even if you want to download some -udebs it will probably not be for all sources you have enabled, so having the possibility of disabling a target by default, but giving the user the option to enable it on a per-source entry basis is better.
2015-08-28implement PDiff patching for compressed filesDavid Kalnischkies
Some additional files like 'Contents' are very big and should therefore kept compressed on the disk, which apt-file did in the past. It also implemented pdiff patching of these files by un- and recompressing these files on-the-fly, with this commit we can do the same – but we can do this in both pdiff patching styles (client and server merging) and secured by hashes. Hashes are in so far slightly complicated as we can't compare the hashes of the compressed files as we might compress them differently than the server would (different compressor versions, options, …), so we must compare the hashes of the uncompressed content. While this commit has changes in public headers, the classes it changes are marked as hidden, so nobody can use them directly, which means the ABI break is internal only.
2015-08-27sources.list and indextargets option for pdiffsDavid Kalnischkies
Disabling pdiffs can be useful occasionally, like if you have a fast local mirror where the download doesn't matter, but still want to use it for non-local mirrors. Also, some users might prefer it to only use it for very big indextargets like Contents.
2015-08-27use always priv-dropping for changelog download as rootDavid Kalnischkies
First of, the temporary directory we download the changelog to needs to be owned by _apt, but that also means that we don't need to check if we could/should drop privs as the download happens to a dedicated tempdir and only after that it is moved to its final location by a privileged user.

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
2015-08-10show or-groups in not-installed recommends and suggests listsDavid Kalnischkies
Further abstracting our new ShowList allows to use it for containers of strings as well giving us the option to implement an or-groups display for the recommends and suggests lists which is a nice trick given that it also helps with migrating the last remaining other cases of old ShowList.
2015-08-10headers are for declarations onlyDavid Kalnischkies
Housekeeping. This used to be embedded in apt-get directly, then moved to into our (then new) private lib and now header and code get a proper separation. Git-Dch: Ignore
2015-08-10rename 'apt-get files' to 'apt-get indextargets'David Kalnischkies
'files' is a bit too generic as a name for a command usually only used programmatically (if at all) by developers, so instead of "wasting" this generic name for this we use "indextargets" which is actually the name of the datastructure the displayed data is stored in. Along with this rename the config options are renamed accordingly.
2015-08-10add c++11 override marker to overridden methodsDavid Kalnischkies
C++11 adds the 'override' specifier to mark that a method is overriding a base class method and error out if not. We hide it in the APT_OVERRIDE macro to ensure that we keep compiling in pre-c++11 standards. Reported-By: clang-modernize -add-override -override-macros Git-Dch: Ignore
2015-08-10merge indexRecords into metaIndexDavid Kalnischkies
indexRecords was used to parse the Release file – mostly the hashes – while metaIndex deals with downloading the Release file, storing all indexes coming from this release and … parsing the Release file, but this time mostly for the other fields. That wasn't a problem in metaIndex as this was done in the type specific subclass, but indexRecords while allowing to override the parsing method did expect by default a specific format. APT isn't really supporting different types at the moment, but this is a violation of the abstraction we have everywhere else and, which is the actual reason for this merge: Options e.g. coming from the sources.list come to metaIndex naturally, which needs to wrap them up and bring them into indexRecords, so the acquire system is told about it as they don't get to see the metaIndex, but they don't really belong in indexRecords as this is just for storing data loaded from the Release file… the result is a complete mess. I am not saying it is a lot prettier after the merge, but at least adding new options is now slightly easier and there is just one place responsible for parsing the Release file. That can't hurt.
2015-08-10support lang= and target= sources.list optionsDavid Kalnischkies
We support arch= for a while, now we finally add lang= as well and as a first simple way of controlling which targets to acquire also target=. This asked for a redesign of the internal API of parsing and storing information about 'deb' and 'deb-src' lines. As this API isn't visible to the outside no damage done through. Beside being a nice cleanup (= it actually does more in less lines) it also provides us with a predictable order of architectures as provides in the configuration rather than based on string sorting-order, so that now the native architecture is parsed/displayed first. Observeable e.g. in apt-get output.

2015-06-15provide a public interface for acquiring changelogsDavid Kalnischkies
Provided is a specialized acquire item which given a version can figure out the correct URI to try by itself and if not provides an error message alongside with static methods to get just the URI it would try to download if it should just be displayed or similar such. The URI is constructed as follows: Release files can provide an URI template in the "Changelogs" field, otherwise we lookup a configuration item based on the "Label" or "Origin" of the Release file to get a (hopefully known) default value for now. This template should contain the string CHANGEPATH which is replaced with the information about the version we want the changelog for (e.g. main/a/apt/apt_1.1). This middleway was choosen as this path part was consistent over the three known implementations (+1 defunct), while the rest of the URI varies widely between them. The benefit of this construct is that it is now easy to get changelogs for Debian packages on Ubuntu and vice versa – even at the moment where the Changelogs field is present nowhere. Strictly better than what apt-get had before as it would even fail to get changelogs from security… Now it will notice that security identifies as Origin: Debian and pick this setting (assuming again that no Changelogs field exists). If on the other hand security would ship its changelogs in a different location we could set it via the Label option overruling Origin. Closes: 687147, 739854, 784027, 787190
2015-06-15implement default apt-get file --release-info modeDavid Kalnischkies
Selecting targets based on the Release they belong to isn't to unrealistic. In fact, it is assumed to be the most used case so it is made the default especially as this allows to bundle another thing we have to be careful with: Filenames and only showing targets we have acquired. Closes: 752702
2015-06-11implement 'apt-get files' to access index targetsDavid Kalnischkies
Downloading additional files is only half the job. We still need a way to allow external tools to know where the files are they requested for download given that we don't want them to choose their own location. 'apt-get files' is our answer to this showing by default in a deb822 format information about each IndexTarget with the potential to filter the records based on lines and an option to change the output format. The command serves also as an example on how to get to this information via libapt.
2015-05-11drop incorrect parameter implicitely converted to boolDavid Kalnischkies
The helper expects to be told if it should generate messages, not where these messages should be printed – as it isn't printing such messages, but puts them in _error. apt-get uses in other methods a helper specialisation which does also print stuff to a stream through, so this is likely a copy&paste error.

2015-03-16stop displaying time of build in online helpJérémy Bobbio
As part of the “reproducible builds” effort [1], we have noticed that apt could not be built reproducibly. One issue is that it uses the __DATE__ and __TIME__ macros of the C preprocessor to display the time of build in the online help. We believe this information not to be really useful to users as they can always look at the package data and metadata to figure it out. The attached patch simply removes this information. All non-documentation packages can then be built reproducibly with our current experimental framework. [David: changed the string slightly to be untranslateable as well] Closes: 774342

2014-11-10use '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. This is a cherry-pick of 1262d35 with some dirty tricks to preserve ABI. LP: 1098738
2014-11-09use pkgAcquire::GetLock instead of own codeDavid Kalnischkies
Do the same with less code in apt-get. This especially ensures that the lock file (and the parent directories) exist before we are trying to lock. It also means that clean now creates the directories if they are missing so we returned to a proper clean state now. Git-Dch: Ignore
2014-11-09streamline display of --help in all toolsDavid Kalnischkies
By convention, if I run a tool with --help or --version I expect it to exit successfully with the usage, while if I do call it wrong (like without any parameters) I expect the usage message shown with a non-zero exit.

2014-11-08better non-virtual metaIndex.LocalFileName() implementationDavid Kalnischkies
We can't add a new virtual method without breaking the ABI, but we can freely add new methods, so for older ABIs we just implement this method with a dynamic_cast, so that clients can be more ignorant about the API here and especially don't need to pull a very dirty trick by assuming internal knowledge (like apt-get did here).
2014-10-23chown finished partial files earlierDavid Kalnischkies
partial files are chowned by the Item baseclass to let the methods work with them. Now, this baseclass is also responsible for chowning the files back to root instead of having various deeper levels do this. The consequence is that all overloaded Failed() methods now call the Item::Failed base as their first step. The same is done for Done(). The effect is that even in partial files usually don't belong to _apt anymore, helping sneakernets and reducing possibilities of a bad method modifying files not belonging to them. The change is supported by the framework not only supporting being run as root, but with proper permission management, too, so that privilege dropping can be tested with them.
2014-10-15check for available space, excluding root reserved blocksDavid Kalnischkies
We are checking the space requirements for ages, but the check uses the free blocks count, which includes the blocks reserved for usage by root. Now that we use an unprivileged user it has no access to these blocks anymore – and more importantly these blocks are a reserve, they shouldn't be used by apt without special encouragement by the user as it would be bad to have dpkg run out of diskspace and maintainerscripts like man-db skip certain actions if not enough space is available freely.
2014-10-15don't drop privileges if _apt has not enough rightsDavid Kalnischkies
Privilege dropping breaks download/source/changelog commands as they require the _apt user to have write permissions in the current directory, which is e.g. the case in /tmp, but not in /root, so we disable the privilege dropping if we deal with such a directory based on idea and code by Michael Vogt. The alternative would be to download always to a temp directory and move it then done, but this breaks partial file support. To resolve this, we could move to one of our partial/ directories, but this would require a lock which would block root from using two of these commands in parallel. As both seems unacceptable we instead let the user choose what to do: Either a directory is setupped for _apt, downloading as root is accepted or – which is potentially even better – an unprivileged user is used for the commands.

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.
2014-10-03apt-get: Create the temporary downloaded changelog inside tmpdirGuillem Jover
The code is creating a secure temporary directory, but then creates the changelog alongside the tmpdir in the same base directory. This defeats the secure tmpdir creation, making the filename predictable. Inject a '/' between the tmpdir and the changelog filename.

2014-09-27cleanup partial directory of lists in apt-get cleanDavid Kalnischkies
Not really the intended usecase for apt-get clean, but users expect it to help them in recovery and it can't really hurt as this directory should be empty if everything was fine and proper anyway. Closes: #762889
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.

2014-08-26add dpkg::source-options for dpkg-source invocationDavid Kalnischkies
dpkg-source can be told to enforce signature checks with --require-valid-signature, but while this isn't feasible as default for Debian itself at the moment, a local admin should be able to use it. This commit also fixes the size limit on the construction of the command being called for dpkg-source and dpkg-buildpackage. Closes: 757534
