2017-09-09drop unused/unimplemented & hidden LoadReleaseInfoDavid Kalnischkies
The relevant calling code as well as the implementation for the deb system was removed 2 years ago with the refactoring of release information storage (b07aeb1a6e24825e534167a737043441e871de9f). This commit removes the the unused remains of this change with no practical effect on anybody (expect codesize) as the methods were declared as hidden and hence only libapt could have called it.

2017-08-24Replace APT_CONST with APT_PURE everywhereJulian Andres Klode
As a follow up to the last commit, let's replace APT_CONST with APT_PURE everywhere to clean stuff up.
2017-07-12Reformat and sort all includes with clang-formatJulian Andres Klode
This makes it easier to see which headers includes what. The changes were done by running git grep -l '#\s*include' \ | grep -E '.(cc|h)$' \ | xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/' To modify all include lines by adding a space, and then running ./git-clang-format.sh.
2017-07-12Drop cacheiterators.h includeJulian Andres Klode
Including cacheiterators.h before pkgcache.h fails because pkgcache.h depends on cacheiterators.h.
2017-06-26fix some unlikely memory leaks in error casesDavid Kalnischkies
The error cases are just as unlikely as the memory leaks to ever cause real problems, but lets play it safe for correctness. Reported-By: scan-build & clang Gbp-Dch: Ignore
2016-11-22Do not use MD5SumValue for Description_md5()Julian Andres Klode
Our profile says we spend about 5% of the time transforming the hex digits into the binary format used by HashsumValue, all for comparing them against the other strings. That makes no sense at all. According to callgrind, this reduces the overall instruction count from 5,3 billion to 5 billion in my example, which roughly matches the 5%.
2016-08-26Add missing includes and external definitionsJulian Andres Klode
Several modules use std::array without including the array header. Bad modules. Some modules use STDOUT_FILENO and friends, or close() without including unistd.h, where they are defined. One module also uses WIFEXITED() without including sys/wait.h. Finally, environ is not specified to be defined in unistd.h. We are required to define it ourselves according to POSIX, so let's do that.
2016-06-29eipp: let apt make a plan, not make stuff planeDavid Kalnischkies
Julian noticed on IRC that I fall victim to a lovely false friend by calling referring to a 'planer' all the time even through these are machines to e.g. remove splinters from woodwork ("make stuff plane"). The term I meant is written in german in this way (= with a single n) but in english there are two, aka: 'planner'. As that is unreleased code switching all instances without any transitional provisions. Also the reason why its skipped in changelog. Thanks: Julian Andres Klode Gbp-Dch: Ignore
2016-06-27eipp: provide the internal planer as an external oneDavid Kalnischkies
Testing the current implementation can benefit from being able to be feed an EIPP request and produce a fully compliant response. It is also a great test for EIPP in general.
2016-06-08edsp: optionally store a compressed copy of the last scenarioDavid Kalnischkies
For bugreports and co it could be handy to have the scenario and all the settings used in it around later for inspection for EDSP like protocols. EDSP might not be the most interesting as the user can still interrupt the process before the solution is applied and users tend to have an opinion on the "rightness" of a solution, so it is disabled by default.
2016-06-06edsp: prevent it from trying to write a cacheDavid Kalnischkies
EDSP(-like) protocols are one-shot processes working on data which exists only as long as they run (as they get feed via a pipe), so trying to write a cache for it is pretty pointless, especially as it will usually fail as the cache files tend to be owned by root, but the process is run as a unpriviledged user (either _apt if called by root, otherwise the user of the caller). So this was in fact only observeable with our testcases which run as non-root and the worst which happens is that a valid cache is overridden with an invalid one which the next run will detect and not use. Git-Dch: Ignore
2016-06-05refactor EDSP classes for better internal reuseDavid Kalnischkies
The classes are all marked as hidden, so changing them is no problem ABI wise and will help with introducing protocols similar to EDSP. The change has no observeable behavior difference, its just code juggling. Git-Dch: Ignore
2016-06-04edsp: use an ID mapping for the internal solverDavid Kalnischkies
Currently an EDSP solver gets send basically all versions which means the absolute count is the same, but that might not be true forever (and with the skipping of rc-only versions it kinda is already) and even if it were true, segfaulting on bad input seems wrong.
2016-02-03edspsystem.cc: include <stdlib.h> for mkdtempFredrik Fornwall
Include <stdlib.h> to ensure that mkdtemp(3) is defined to improve general portability and fix a specific build failure on Android. Closes: #807367
2016-01-26remove unused Description methods in listparsersDavid Kalnischkies
These virtual methods are implemented in hidden classes, so we can drop them without breaking the ABI. Git-Dch: Ignore
2015-11-04wrap every unlink call to check for != /dev/nullDavid Kalnischkies
Unlinking /dev/null is bad, we shouldn't do that. Also, we should print at least a warning if we tried to unlink a file but didn't manage to pull it of (ignoring the case were the file is /dev/null or doesn't exist in the first place). This got triggered by a relatively unlikely to cause problem in pkgAcquire::Worker::PrepareFiles which would while temporary uncompressed files (which are set to keep compressed) figure out that to files are the same and prepare for sharing by deleting them. Bad move. That also shows why not printing a warning is a bad idea as this hide the error for in non-root test runs. Git-Dch: Ignore
2015-11-04sanify API to get 'the' candidate versionDavid Kalnischkies
This was discussed a while ago on #debian-apt and now that I see myself making this mistake lets bite the bullet and fix it in the easy way out version: Using a new name which fits with a similar named setter and deprecate the old method instead of 'hostily' changing API. Closes: #803471

2015-09-14implement autobit and pinning in EDSP solver 'apt'David Kalnischkies
The parser creates a preferences as well as an extended states file based on the EDSP scenario file, which isn't the most efficient way of dealing with this as thes text files have to be parsed again by another layer of the code, but it needs the least changes and works good enough for now. The 'apt' solver is in the end just a test solver like dump.

2015-08-10parse packages from all architectures into the cacheDavid Kalnischkies
Now that we can dynamically create dependencies and provides as needed rather than requiring to know with which architectures we will deal before running we can allow the listparser to parse all records rather than skipping records of "unknown" architectures. This can e.g. happen if a user has foreign architecture packages in his status file without dpkg knowing about this architecture (or apt configured in this way). A sideeffect is that now arch:all packages are (correctly) recorded as available from any Packages file, not just from the native one – which has its downsides for the resolver as mixed-arch source packages can appear in different architectures at different times, but that is the problem of the resolver and dealing with it in the parser is at best a hack (and also depends on a helpful repository). Another sideeffect is that his allows :none packages to appear in Packages files again as we don't do any kind of checks now, but given that they aren't really supported (anymore) by anyone we can live with that.
2015-08-10elimate duplicated code in pkgIndexFile subclassesDavid Kalnischkies
Trade deduplication of code for a bunch of new virtuals, so it is actually visible how the different indexes behave cleaning up the interface at large in the process. Git-Dch: Ignore
2015-08-10add volatile sources support in libapt-pkgDavid Kalnischkies
Sources are usually defined in sources.list (and co) and are pretty stable, but once in a while a frontend might want to add an additional "source" like a local .deb file to install this package (No support for 'real' sources being added this way as this is a multistep process). We had a hack in place to allow apt-get and apt to pull this of for a short while now, but other frontends are either left in the cold by this and/or the code for it looks dirty with FIXMEs plastering it and has on top of this also some problems (like including these 'volatile' sources in the srcpkgcache.bin file). So the biggest part in this commit is actually the rewrite of the cache generation as it is now potentially a three step process. The biggest problem with adding support now through is that this makes a bunch of previously mostly unusable by externs and therefore hidden classes public, so a bit of further tuneing on this now public API is in order…
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
2015-08-10make 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
2015-06-16add d-pointer, virtual destructors and de-inline de/constructorsDavid Kalnischkies
To have a chance to keep the ABI for a while we need all three to team up. One of them missing and we might loose, so ensuring that they are available is a very tedious but needed task once in a while. Git-Dch: Ignore
2015-06-15populate the Architecture field for PackageFilesDavid Kalnischkies
This is mainly visible in the policy, so that you can now pin by b= and let it only effect Packages files of this architecture and hence the packages coming from it (which do not need to be from this architecture, but very likely are in a normal repository setup). If you should pin by architecture in this way is a different question… Closes: 687255
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.
2014-11-08mark internal interfaces as hiddenDavid Kalnischkies
We have a bunch of classes which are of no use for the outside world, but were still exported and so needed to preserve ABI/API. Marking them as hidden to not export them any longer is a big API break in theory, but in practice nobody is using them – as if they would its a bug.
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…
2014-06-18cleanup 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.
