2015-08-10just-in-time creation for (implicit) ProvidesDavid Kalnischkies
Expecting the worst is easy to code, but has its disadvantages e.g. by creating package structures which otherwise would have never existed. By creating the provides instead at the time a package structure is added we are well prepared for the introduction of partial architectures, massive amounts of M-A:foreign (and :allowed) and co as far as provides are concerned at least. We have something relatively similar for dependencies already. Many tests are added for both M-A states and the code cleaned to properly support implicit provides for foreign architectures and architectures we 'just' happen to parse. Git-Dch: Ignore
2015-08-10hide implicit deps in apt-cache again by defaultDavid Kalnischkies
Before MultiArch implicits weren't a thing, so they were hidden by default by definition. Adding them for MultiArch solved many problems, but having no reliable way of detecting which dependency (and provides) is implicit or not causes problems everytime we want to output dependencies without confusing our observers with unneeded implementation details. The really notworthy point here is actually that we keep now a better record of how a dependency came to be so that we can later reason about it more easily, but that is hidden so deep down in the library internals that change is more the problems it solves than the change itself.
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
2015-08-10bunch of micro-optimizations for depcacheDavid Kalnischkies
DepCache functions are called a lot, so if we can squeeze some drops out of them for free we should do so. Takes also the opportunity to remove some whitespace errors from these functions. 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. Git-Dch: Ignore
2015-06-12store Release files data in the CacheDavid Kalnischkies
We used to read the Release file for each Packages file and store the data in the PackageFile struct even through potentially many Packages (and Translation-*) files could use the same data. The point of the exercise isn't the duplicated data through. Having the Release files as first-class citizens in the Cache allows us to properly track their state as well as allows us to use the information also for files which aren't in the cache, but where we know to which Release file they belong (Sources are an example for this). This modifies the pkgCache structs, especially the PackagesFile struct which depending on how libapt users access the data in these structs can mean huge breakage or no visible change. As a single data point: aptitude seems to be fine with this. Even if there is breakage it is trivial to fix in a backportable way while avoiding breakage for everyone would be a huge pain for us. Note that not all PackageFile structs have a corresponding ReleaseFile. In particular the dpkg/status file as well as *.deb files have not. As these have only a Archive property need, the Component property takes over this duty and the ReleaseFile remains zero. This is also the reason why it isn't needed nor particularily recommended to change from PackagesFile to ReleaseFile blindly. Sticking with the earlier is usually the better option.

2015-04-12parse specific-arch dependencies correctly on single-arch systemsDavid Kalnischkies
On single-arch the parsing was creating groupnames like 'apt:amd64' even through it should be 'apt' and a package in it belonging to architecture amd64. The result for foreign architectures was as expected: The dependency isn't satisfiable, but for native architecture it means the wrong package (ala apt:amd64:amd64) is linked so this is also not satisfiable, which is very much not expected. No longer excluding single-arch from this codepath allows the generation of the correct links, which still link to non-exisiting packages for foreign dependencies, but natives link to the expected native package just as if no architecture was given. For negative arch-specific dependencies ala Conflicts this matter was worse as apt will believe there isn't a Conflict to resolve, tricking it into calculating a solution dpkg will refuse. Architecture specific positive dependencies are rare in jessie – the only one in amd64 main is foreign –, negative dependencies do not even exist. Neither class has a native specimen, so no package in jessie is effected by this bug, but it might be interesting for stretch upgrades. This also means the regression potential is very low. Closes: 777760
2015-03-16parse arch-qualified Provides correctlyHelmut Grohne
The underlying problem is that libapt-pkg does not correctly parse these provides. Internally, it creates a version named "baz:i386" with architecture amd64. Of course, such a package name is invalid and thus this version is completely inaccessible. Thus, this bug should not cause apt to accept a broken situation as valid. Nevertheless, it prevents using architecture qualified depends. Closes: 777071

2014-10-13do not inline virtual destructors with d-pointersDavid Kalnischkies
Reimplementing an inline method is opening a can of worms we don't want to open if we ever want to us a d-pointer in those classes, so we do the only thing which can save us from hell: move the destructors into the cc sources and we are good. Technically not an ABI break as the methods inline or not do the same (nothing), so a program compiled against the old version still works with the new version (beside that this version is still in experimental, so nothing really has been build against this library anyway). Git-Dch: Ignore
2014-10-08Update Status field values handlingGuillem Jover
Remove long obsolete (hold, hold-reinstreq, removal-failed) or just wrong (post-inst-failed vs postinst-failed) values, that have been autoconverted by dpkg at run-time to their new equivalents, so there should not be any such instance in any recent system (removal-failed since dpkg 1.1.4 in Apr 1996, hold and hold-reinstreq since dpkg 1.2.0 in May 1996). dpkg even stopped doing the mapping in 1.15.4 and 1.15.8 respectively. At the same time sort the list in the same order as they appear in the dpkg code.

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.
2014-09-27drop stored StringItems in favor of in-memory mappingsDavid Kalnischkies
Strings like Section names or architectures are needed vary often. Instead of writing them each time we need them, we deploy sharing for these special strings. Until now, this was done with a linked list of strings in which we would search, which was stored in the cache. It turns out we can do this just as well in memory as well with a bunch of std::map's. In memory means here that it isn't available anymore if we have a partly invalid cache, but that isn't much of a problem in practice as the status file is compared to the other files we parse very small and includes mostly duplicates, so the space we would gain by storing is more or less equal to the size of the stored linked list…

2014-08-26support versioned provides as implemented by dpkgDavid Kalnischkies
APT supported versioned provides for a long while in an attempt to get it working with rpm. While this support is old, we can be relatively sure that it works as versioned provides are used internally to make Multi-Arch:foreign work. Previous versions of apt will print a warning indicating that the versioned provides is ignored, so that something which "Provides: foo (= 2)" doesn't provide anything. Note that dpkg does allow only a equals-relation in the provides line as anything else is deemed too complex. apt doesn't support anything else either and such a support would require potentially big changes.

2014-07-07handle moved mmap after UniqFindTagWrite callDavid Kalnischkies
A call to UniqFindTagWrite can trigger the need for a bigger mmap, which is usually done by moving it, but with this move all pointers into it become invalid (and have to be remapped). The compiler calculates the pointer before the execution of the call though, so it tries to store the returned value at the old location, resulting in a segfault. We solve this by use of a temprorary variable as we did in the other instances of this problem before. Closes: #753941
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 …).
2014-06-18cleanup datatypes mix used in binary cacheDavid Kalnischkies
We had a wild mixture of (unsigned) int, long and long long here without much sense, so this commit adds a few typedefs to get some sense in the typesystem and ensures that a ID isn't sometimes computed as int, stored as long and compared with a long long… as this could potentially bite us later on as the size of the archive only increases over time.
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'.

2014-03-13support DEB_BUILD_PROFILES and -P for build profilesDavid Kalnischkies
Inspired by the rest of the patch in 661537, but abstract the parsing of various ways of setting the build profiles more so it can potentially be reused and all apt parts have the same behaviour. Especially config options, cmdline options and environment will not be combined as proposed as this isn't APTs usual behaviour and dpkg doesn't do it either, so one overrides the other as it normally does.

2013-09-26don't strip :any from dependencies in single-archDavid Kalnischkies
The parser goes a bit to far by stripping :any from dependencies in a single architecture environment. the flag "Multi-Arch: allowed" doesn't care any architecture restrictions in that case (as in single arch everything is native), but it still limits the possible versions statisfying the dependency so stripping :any over-simplifies in upgrade situations from "Multi-Arch: none" to "Multi-Arch: allowed". Closes: 723586
2013-08-15init the pkgTagFile with the size of the Release fileDavid Kalnischkies
Release files are basically one big Section, so we might safe some Resize circles by starting with the filesize. Git-Dch: Ignore
2013-08-08use pkgTagFile to parse "header" of Release filesDavid Kalnischkies
The handwritten parsing here was mostly done as we couldn't trust the Release file we got, but nowadays we are sure that the Release file is valid and contains just a single section we want it to include. Beside reducing code it also fixes a bug: Fieldnames in deb822 formatted files are case-insensitive and pkgTagFile does it correctly, but this selfbuilt stuff here didn't.
2013-06-20handle missing "Description" in apt-cache showDavid Kalnischkies
do not blindly assume that all packages stanzas have a "Description:" field in 'apt-cache show' as well as in the cache creation itself. We instead assume now that if the stanza has a Description, it will not be the first field as we look out for "\nDescription" to take care of MD5sum as well as (maybe ignored) translated Descriptions embedded in the package stanza.
