* reimplement build-dep via apts normal resolverDavid Kalnischkies2016-01-2515-427/+398
| | | | | | | | | | | | | | | | | | | | | | | | build-dep was implemented by parsing the build-dependencies of a package and figuring out which packages to install/remove based on this. That means that for the first level of dependencies build-dep was implementing its very own resolver with all the benefits (aka: bugs) this gives us for not using the existing resolver for all levels. Making this work involves generating a dummy binary package with fitting Depends and Conflicts and as we can't create them out of thin air the cache generation needs to be involved so we end up writing a Packages file which we want to parse – after we have parsed the other Packages files already. With .dsc/.deb files we could add them before we started parsing anything. With a bit of care we can avoid generating too much data we have to throw away again (as many parts assume that e.g. the count of packages doesn't change midair), so that on a speed front there shouldn't be much of a difference, but output can be slightly confusing as if we have a completely valid cache on disk the "Reading package lists... Done" is printed two times – but apt is pretty quick about it in that case. Closes: #137560, #444930, #489911, #583914, #728317, #812173
* use consistently the last : as name:arch separatorDavid Kalnischkies2016-01-252-2/+2
| | | | | | | | Proper debian packages do not contain ':' in the package name, so for real packages this is a non-issue, but apt itself frequently makes use of packages with such an illegal name for internal proposes. Git-Dch: Ignore
* prefer upgrading installed provides satisfierDavid Kalnischkies2016-01-251-0/+2
| | | | | | | | If you have chosen to install a foreign architecture provider it is more reasonable to keep this provider instead of removing this one to replace it with a newer version from a (usually) more preferred arch. Git-Dch: Ignore
* treat an empty dependency field just like it doesn't existDavid Kalnischkies2016-01-251-1/+1

* always create pkg at the time pkg:arch is createdDavid Kalnischkies2016-01-253-21/+41
| | | | | | | | | To resolve dependencies like "pkg:arch" we create a package with the name "pkg:arch" and the architecture "any". We create these packages only if a dependency needs it as these kind of dependencies aren't that common. This commit ensured that in the even this architecture specific dependency is the only relation this package has we still create the underlying package to have them available in provides resolution.

* Remap another (non-parameter) StringViewJulian Andres Klode2016-01-231-1/+3
| | | | | | | | | I only looked at parameters in the previous commit, which was not enough: One place also generated local string views. In this case, we only need to make ArchA dynamic, as NameA is not used after the FindPkg() call. Gbp-Dch: ignore
* Remap StringView instances pointing into the cacheJulian Andres Klode2016-01-231-0/+19
| | | | | | | | | | | | | | | | | | | | It turns out that StringViews might need to be remapped in some places because they come from the cache. For example, some sites pass a Ver.VerStr() to NewProvides(). Such a StringView would become invalid during the duration of the call if the cache is remapped, causing the program to die with a segmentation fault. We can take care of those issues by remapping string views in the same way we remap all the iterators. String views are only remapped if they point into the cache though, this allows us to write more generic code on the callee site without having to check whether the view points into the cache or not. That's not as efficient as possible, but the overhead does not appear to be measurable. Closes: #812251
* Pass the old map size to ReMap()Julian Andres Klode2016-01-232-5/+8
| | | | | | | This allows us to check if a value to be remapped was inside the cache or not, which will become useful at a later point. Gbp-Dch: ignore

* string_view: Drop constexpr constructor for standard compatibilityJulian Andres Klode2016-01-152-18/+12
| | | | | | | | | | | | | APT::StringView is supposed to be a temporary measure, until support for the standardized string_view is widely available. Introducing additional unstandardized features just makes porting to the standard version harder. The constexpr constructor also won't have any real effect on most systems, as the compiler will happily optimise the strlen() call away for constant strings. Gbp-Dch: ignore

* return correct position in APT::StringView::(r)findDavid Kalnischkies2016-01-151-8/+16
| | | | | | | The position returned is supposed to be the position of the character counted from the start of the string, but if we used the substr calling overloads the skipped over prefix wasn't considered. The pos parameter of rfind had also the wrong semantic.

* revert file-hash based action-merging in acquireDavid Kalnischkies2016-01-152-2/+1
| | | | | | | | | | | | | | | Introduced in 9d2a8a7388cf3b0bbbe92f6b0b30a533e1167f40 apt tries to merge actions like downloading the same (as judged by hashes) file into doing it once. The implementation was very simple in that it isn't planing at all. Turns out that it works 90% of the time just fine, but has issues in more complicated situations in which items can be in different stages downloading different files emitting potentially the "wrong" hash – like while pdiffs are worked on we might end up copying the patch instead of the result file giving us very strange errors in return. Reverting the change until we can implement a better planing solution seems to be the best course of action even if its sad. Closes: 810046
* fix M-A:foreign provides creation for unknown archsDavid Kalnischkies2016-01-144-6/+26
| | | | | | | | Architectures for packages which do not belong to the native nor a foreign architecture (dubbed barbarian for now) which are marked M-A:foreign still provide in their own architecture even if not for others. Also, other M-A:foreign (and allowed) packages provide in these barbarian architectures.

| | | | | | | | Parsing XML entity files in shell isn't exactly nice and causing the substitution with a while-read loop isn't either, but it seems to be good enough for the moment without changing too much. Thanks: Niels Thykier for reporting on IRC

| | | | | | | | | This prevents a test suite failure on systems with weird umasks. Also set umask 000 at the beginning so we can actually check for that anywhere. Gbp-Dch: ignore

* search: Handle packages without descriptionJulian Andres Klode2016-01-111-2/+5
| | | | | | | | | | | | | If a package has no description, we would crash in search. While this should not happen, there seem to be some weird cases where it does. A safer way might be to make the whole parser thing safe against this, so pkgRecords::Lookup(Desc.FileList()) works and returns a parser where all values are empty. This would also fix all other instances of this bug, if there are any. Closes: #810622
* Version the build-depends on liblz4-dev to >= 0.0~r126Julian Andres Klode2016-01-091-1/+1
| | | | | We need r126 of lz4, as this introduces the lz4frame.h header.
* Bump dpkg-dev and debhelper build-dep to make lintian happyJulian Andres Klode2016-01-091-1/+1

* Do not break apt-file (<< 3.0~exp1~), 2.X works fineJulian Andres Klode2016-01-091-1/+1
| | | | | There's no point in breaking all older apt-file versions just because one old experimental upload was broken.

* libapt-pkg5.0: Add Breaks appstream (<< 0.9.0-3~)Julian Andres Klode2016-01-081-1/+1
| | | | | | This ensures that a compatible version of appstream is installed, that is, one that disables lz4 compression for its data.
* Store the size of strings in the cacheJulian Andres Klode2016-01-084-6/+24
| | | | | By storing the size of the string in the cache, we can make use of it when comparing the names in the hashtable in pkgCache::FindGrp.

* remove uncompressed leftover partial file before pdiff bootstrapDavid Kalnischkies2016-01-082-8/+27
| | | | | | | The code already deals with compressed leftovers, but forgot the uncompressed files. The opertunity is picked to reorder this code and add debug messages about the actions taken as well as produce such a leftover file in the associated testcase.
* use filesize of compressed pdiffs for the limit if possibleDavid Kalnischkies2016-01-082-14/+55
| | | | | | | | | | | | With the addition of the $HASH-Download field in the .diff/Index we got the size of the compressed patches for 'free', so if that information is available we can use it for a more fitting calculation of the size requirements of the patches vs. the complete file. Note that this predicts a too small size in the transition case in which the information isn't available for all patches, but figuring this out would be a lot of code for practically nothing as only one update can ever be in such a transition phase.
* tests: limit autotest-functionname generation to sane charactersDavid Kalnischkies2016-01-081-3/+3
| | | | | | | | Some (older) versions of bash seem to be allergic to a method named "aptautotest_grep_^apt" (note the caret). Unlikely that we are going to write autotests for such commands so we could just skip those, but lets instead just use "normal" characters in the names and strip the rest as we already did with the (arguable more common) '-'.
* support '-' and no parameter for stdin in apt-helper cat-fileDavid Kalnischkies2016-01-082-22/+22
| | | | | | This way it works more similar to the compressor binaries, which we can relief in this way from their job in the test framework avoiding the need of adding e.g. liblz4-tool to the test dependencies.
* keep compressed indexes in a low-cost formatDavid Kalnischkies2016-01-0814-128/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | Downloading and storing are two different operations were different compression types can be preferred. For downloading we provide the choice via Acquire::CompressionTypes::Order as there is a choice to be made between download size and speed – and limited by whats available in the repository. Storage on the other hand has all compressions currently supported by apt available and to reduce runtime of tools accessing these files the compression type should be a low-cost format in terms of decompression. apt traditionally stores its indexes uncompressed on disk, but has options to keep them compressed. Now that apt downloads additional files we also deal with files which simply can't be stored uncompressed as they are just too big (like Contents for apt-file). Traditionally they are downloaded in a low-cost format (gz) as repositories do not provide other formats, but there might be even lower-cost formats and for download we could introduce higher-cost in the repositories. Downloading an entire index potentially requires recompression to another format, so an update takes potentially longer – but big files are usually updated via pdiffs which has to de- and re-compress anyhow and does it on the fly anyhow, so there is no extra time needed and in general it seems to be benefitial to invest the time in update to save time later on file access.
