2016-02-04Release 1.2.21.2.2Julian Andres Klode
2016-02-04Use some semantically more correct buffer operationsJulian Andres Klode
When writing into the buffer write to free() bytes starting at getend(), instead of buffersize_max bytes at get() -> get() is a read pointer. This makes no difference in practice though, as we reset the buffer before the call, so start = end = 0. Gbp-Dch: ignore
2016-02-04test: Fix apt-key tests to work with current gpg 2.1Julian Andres Klode
2016-02-04Correctly report write errors when flushing buffered writerJulian Andres Klode
We cannot just return false without setting an error, as InternalWrite does not set one itself.
2016-02-04rred: If there were I/O errors, failJulian Andres Klode
We basically ignored errors from writing and flushing, let's not do that.
2016-02-04NEWS: Prefix the keep deb option with Binary::apt::Julian Andres Klode
I find the per-binary overrides a bit confusing in their current form, but let's tell the user the truth. Closes: #812111
2016-02-04Merge branch 'master' of github.com:adrian17/aptJulian Andres Klode
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
2016-02-03Avoid temporary strings in SubstVar.Adrian Wielgosik
Microoptimization, but still gives a measurable 2-3% improvement when using commands with lots of output like `apt list`.
2016-02-03avoid building dependency tree in 'source' commandDavid Kalnischkies
We don't need the dependencies for obvious reasons and we don't need the candidate version either, so building a pkgDepCache is wasted effort, which we can stop doing now that build-dep cleared the path.
2016-02-03use pkgCache::VS instead of pkgDepCache::VS()David Kalnischkies
The later just calls the earlier, but the later needs the fullblown dependency cache to be initialized, which is a very costly operation and isn't done anymore that early in the run as we would need to throw away and rebuild it again after we got all the information about source pkgs. As we end up with a nullptr for the pkgDepCache, we use a slightly longer calling convention to make sure that we use the pkgCache directly, avoiding nullptr induced segfaults and costly operations.

2016-02-03Drop the g++ build-dep, transition is doneJulian Andres Klode
It's not cross-satisfiable. Reported-by: Helmut Grohne

2016-02-02Try avoiding loading long package descriptionAdrian Wielgosik
It's a fairly expensive call and it's called on every package, even though it's usually only used when we're interested in a small number of packages. Long description is currently only shown by this function when using `apt search X --full`. On my PC, this patch speeds up `apt list` by roughly 20% and `apt list --installed` by 1-2%.

Closes: 813467
2016-02-01Do not buffer writes larger than the buffer if possibleJulian Andres Klode
It makes no sense to split a large block into multiple small blocks, so when we have the chance to write them unbuffered, do so.
2016-02-01BufferedWriteFileFdPrivate: Simplify InternalWrite()Julian Andres Klode
We do not need the loop, FileFd::Private() handles this for us. Gbp-Dch: ignore
2016-02-01simple_buffer::write: Use free() instead of maxsize - size()Julian Andres Klode
We want to check whether the amount of free space is smaller than the requested write size. Checking maxsize - size() is incorrect for bufferstart >= 0, as size() = end - start. Gbp-Dch: ignore
2016-01-31support <libc>-<kernel>-<cpu> in architecture specsDavid Kalnischkies
APT has a different understanding than dpkg (#748936) what matches and what doesn't match an architecture specification as it isn't converting back (and forward) to Debian triplets. That has to eventually be solved some way or the other, but until that happens we change the matching in apt so that porters can continue their work on non-gnu libc-ports even if policy doesn't specify that yet (and dpkg just supporting it "by accident" via triplets). The initial patch was reformatted, fixed in terms of patterns containing "any-any", dealing with expanding an arch without libc to gnu while a pattern expands libc to any, the parsedepends test was fixed (the new if's were inserted one step too early) and another test just for the specifications added. Closes: #812212 Thanks: Bálint Réczey for initial patch

2016-01-27only warn about missing/invalid Date field for nowDavid Kalnischkies
The Date field in the Release file is useful to avoid allowing an attacker to 'downgrade' a user to earlier Release files (and hence to older states of the archieve with open security bugs). It is also needed to allow a user to define min/max values for the validation of a Release file (with or without the Release file providing a Valid-Until field). APT wasn't formally requiring this field before through and (agrueable not binding and still incomplete) online documentation declares it optional (until now), so we downgrade the error to a warning for now to give repository creators a bit more time to adapt – the bigger ones should have a Date field for years already, so the effected group should be small in any case. It should be noted that earlier apt versions had this as an error already, but only showed it if a Valid-Until field was present (or the user tried to used the configuration items for min/max valid-until). Closes: 809329
2016-01-27deal better with (very) small apt::cache-start valuesDavid Kalnischkies
It is a bit academic to support values which aren't big enough to fit even the hashtables without resizing, but cleaning up ensures that we do the right thing (aka not segfaulting) even if something goes wrong in these deep layers. You still can't have very very small values through… Git-Dch: Ignore
2016-01-26convert Version() and Architecture() to APT::StringViewDavid Kalnischkies
Part of hidden classes, so conversion is abi-free. Git-Dch: Ignore
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
2016-01-26get sources for packages in multiple releases againDavid Kalnischkies
In 321213f0dcdcdaab04e01663e7a047b261400c9c Andreas Cadhalpun corrected the incorrect overriding of earlier better-fitting results with later (semi-)matches – but that broke the case in which packages are in multiple releases in the same version (and the user has both releases configured). Closes: 812497
2016-01-26parse version correctly from binary Source fieldDavid Kalnischkies
In commit a221efc331693f8905da870141756c892911c433 I promoted the source package name and version to the binary cache for faster access by e.g. EDSP, but due to changing the interpretation length to soon we always ignored the version part of the Source field, so that packages ended up having the binary version as source version – which while usually just fine it is wrong for binary rebuilds. Closes: 812492
2016-01-26stablize gtest testcase environmentDavid Kalnischkies
Avoid the dependency on a specific current path for the tar test and ensure that _system is correctly initialized (gcc-6 runs into a segfault otherwise and with it fixed starts to depend on the multi-arch configuration of the running system… not good). Git-Dch: Ignore

2016-01-26drop explicit check for EWOULDBLOCK if it has the same value as EAGAINDavid Kalnischkies
gcc correctly reports that we check for the same value twice, expect that the manpage of read(2) tells us to do it for portability, so to make both sides happy lets add a little #if'ing here. Reported-By: gcc-6 Git-Dch: Ignore
2016-01-26Delete copy constructor and operator= for DynamicJulian Andres Klode
This would mess up reference counting and should not be allowed (it could be implemented correctly, but it would not be efficient and we do not need it). Gbp-Dch: ignore

2016-01-25reimplement build-dep via apts normal resolverDavid Kalnischkies
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
2016-01-25use consistently the last : as name:arch separatorDavid Kalnischkies
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
2016-01-25prefer upgrading installed provides satisfierDavid Kalnischkies
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
2016-01-25treat an empty dependency field just like it doesn't existDavid Kalnischkies
Git-Dch: Ignore
2016-01-25always create pkg at the time pkg:arch is createdDavid Kalnischkies
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.

2016-01-23Remap another (non-parameter) StringViewJulian Andres Klode
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
2016-01-23Remap StringView instances pointing into the cacheJulian Andres Klode
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
2016-01-23Pass the old map size to ReMap()Julian Andres Klode
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

2016-01-15string_view: Drop constexpr constructor for standard compatibilityJulian Andres Klode
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
