2015-05-11improve partial/ cleanup in abort and failure casesDavid Kalnischkies
Especially pdiff-enhanced downloads have the tendency to fail for various reasons from which we can recover and even a successful download used to leave the old unpatched index in partial/. By adding a new method responsible for making the transaction of an individual file happen we can at specialisations especially for abort cases to deal with the cleanup. This also helps in keeping the compressed indexes around if another index failed instead of keeping the decompressed files, which we wouldn't pick up in the next call.

2015-04-19a hit on Release files means the indexes will be hits tooDavid Kalnischkies
If we get a IMSHit for the Transaction-Manager (= the InRelease file or as its still supported fallback Release + Release.gpg combo) we can assume that every file we would queue based on this manager, but already have locally is current and hence would get an IMSHit, too. We therefore save us and the server the trouble and skip the queuing in this case. Beside speeding up repetative executions of 'apt-get update' this way we also avoid hitting hashsum errors if the indexes are in fact already updated, but the Release file isn't yet as it is the case on well behaving mirrors as Release files is updated last. The implementation is a bit harder than the theory makes it sound as we still have to keep reverifying the Release files (e.g. to detect now expired once to avoid an attacker being able to silently stale us) and have to handle cases in which the Release file hits, but some indexes aren't present (e.g. user added a new foreign architecture).
2015-04-19refactor calculation of final lists/ name from URIDavid Kalnischkies
Calculating the final name of an item which it will have after everything is done and verified successfully is suprisingly complicated as while they all follow a simple pattern, the URI and where it is stored varies between the items. With some (abibreaking) redesign we can abstract this similar to how it is already down for the partial file location. Git-Dch: Ignore
2015-04-19unsigned Release files can expire, tooDavid Kalnischkies
Checking Valid-Until on an unsigned Release file doesn't give us any security brownie points as an attacker could just change the date and in practice repositories with unsigned Release files will very likely not have a Valid-Until date, but for symetry and the fact that being unsigned is currently just a warning, while expired is a fatal error.
2015-04-19ensure lists/ files have correct permissions after apt-cdrom addDavid Kalnischkies
Its a bit unpredictable which permissons and owners we will encounter on a CD-ROM (or a USB stick, as apt-cdrom is responsible for those too), so we have to ensure in this codepath as well that everything is nicely setup without waiting for a 'apt-get update' to fix up the (potential) mess.
2015-04-19calculate hashes while downloading in httpsDavid Kalnischkies
We do this in HTTP already to give the CPU some exercise while the disk is heavily spinning (or flashing?) to store the data avoiding the need to reread the entire file again later on to calculate the hashes – which happens outside of the eyes of progress reporting, so you might ended up with a bunch of https workers 'stuck' at 100% while they were busy calculating hashes. This is a bummer for everyone using apt as a connection speedtest as the https method works slower now (not really, it just isn't reporting done too early anymore).

2015-04-19calculate only expected hashes in methodsDavid Kalnischkies
Methods get told which hashes are expected by the acquire system, which means we can use this list to restrict what we calculate in the methods as any extra we are calculating is wasted effort as we can't compare it with anything anyway. Adding support for a new hash algorithm is therefore 'free' now and if a algorithm is no longer provided in a repository for a file, we automatically stop calculating it. In practice this results in a speed-up in Debian as we don't have SHA512 here (so far), so we practically stop calculating it.
2015-04-19if we can, use gccs __builtin_swap methodsDavid Kalnischkies

2015-04-19use SHA2 unrolled code as its a bit fasterDavid Kalnischkies
Upstream claims its faster if combined with an optimizing compiler and I can confirm that in some tests, so lets see how it works out in practice. Git-Dch: Ignore
2015-04-19handle servers closing encoded connections correctlyDavid Kalnischkies
Servers who advertise that they close the connection get the 'Closes' encoding flag, but this conflicts with servers who response with a transfer-encoding (e.g. encoding) as it is saved in the same flag. We have a better flag for the keep-alive (or not) of the connection anyway, so we check this instead of the encoding. This is in practice not much of a problem as real servers we talk to are HTTP1.1 servers (with keep-alive) and there isn't much point in doing chunked encoding if you are going to close anyway, but our simple testserver stumbles over this if pressed and its a bit cleaner, too. Git-Dch: Ignore
2015-04-19send Alt-* info for uncompressed based on any compressionsDavid Kalnischkies
file sends information about the uncompressed file if it can find it as well as for the compressed file. This was done only for gzip so far, but we support more compression types. That this information isn't used a lot is a different story. Git-Dch: Ignore

2015-04-19improve https method queue progress reportingDavid Kalnischkies
The worker expects that the methods tell him when they start or finish downloading a file. Various information pieces are passed along in this report including the (expected) filesize. https was using a "global" struct for reporting which made it 'reuse' incorrect values in some cases like a non-existent InRelease fallbacking to Release{,.gpg} resulting in a size-mismatch warning. Reducing the scope and redesigning the setting of the values we can fix this and related issues. Closes: 777565, 781509 Thanks: Robert Edmonds and Anders Kaseorg for initial patchs
2015-04-19do not unlink https file on general errorDavid Kalnischkies
It might be quite interesting which file (content) made curl freak out and other methods keep the file around as well. Git-Dch: Ignore
2015-04-19demote missing gtest to a buildtime warningDavid Kalnischkies
We just need it for unit tests and our debian/rules file actually skips calling them if nocheck is given… but this fails anyhow as we declared a hard-dependency on it. Demoting the error to a warning in configuration and adding a test in the 'make test' path with a friendly message allows nocheck to be useful again. (Running unit tests is fully encouraged of course, but bootstrappers and co do not need to be burdened with this stuff)
2015-04-13release 1.0.9.8David Kalnischkies
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
2015-04-10test for or-group choice behaviour in upgradeDavid Kalnischkies
In #780028 we were discussing how the or-group order should be more important than keep-back decisions of 'upgrade'. We have this behaviour, but to ensure it stays this way lets add a test for it. Git-Dch: Ignore
2015-04-10add a simple unit test for acquire progressDavid Kalnischkies
This isn't testing much of the 'complex' parts, but its better than nothing for now. Git-Dch: Ignore
2015-04-10reimplement the last uses of sprintfDavid Kalnischkies
Working with strings c-style is complicated and error-prune, so by converting to c++ style we gain some simplicity and avoid buffer overflows by later extensions. Git-Dch: Ignore
2015-04-07keyids in "apt-key del" should be case-insensitiveDavid Kalnischkies
gnupg is case-insensitive about keyids, so back then apt-key called it directly any keyid was accepted, but now that we work more with the keyid ourself we regressed to require uppercase keyids by accident. This is also inconsistent with other apt-key commands which still use gnupg directly. A single case-insensitive grep and we are fine again. Closes: 781696
2015-04-07demote VectorizeString gcc attribute from const to pureDavid Kalnischkies
g++-5 generates a slightly broken libapt which doesn't split architecture configurations correctly resulting in e.g. Packages files requested for the bogus architecture 'amd64,i386' instead of for amd64 and i386. The reason is an incorrectly applied attribute marking the function as const, while functions with pointer arguments are not allowed to be declared as such (note that char& is a char* in disguise). Demoting the attribute to pure fixes this issue – better would be dropping the & from char but that is an API change… Neither earlier g++ versions nor clang use this attribute to generate broken code, so we don't need a rebuild of dependencies or anything and g++-5 isn't even included in jessie, but the effect is so strange and apt popular enough to consider avoiding this problem anyhow.
2015-04-07fix crash in order writing in pkgDPkgPM::WriteApportReport()Michael Vogt
libapt can be configured to write various bits of information to a file creating a report via apport. This is disabled by default in Debian and apport residing only in /experimental so far, but Ubuntu and other derivatives have this (in some versions) enabled by default and there is no regression potentially here. The crash is caused by a mismatch of operations vs. strings for operations, so adding the missing strings for these operations solves the problem. [commit message by David Kalnischkies] LP: #1436626
2015-04-07avoid depends on std::string implementation for pkgAcquire::Item::ModeDavid Kalnischkies
In /experimental this is resolved by deprecating Mode and moving to a new std::string, but that breaks ABI of course, so that was out of question. We can't change to a malloc/free style c-string either as Mode is public and hence a library user could be setting this as well. std::string implementors actually helped us out here with copy-on-write which means that while the variable "obviously" runs out of scope here, in reality you get the correct result as the string we work with here comes from the configuration in which it is still valid. Such a dependency on magic is bad of course, but its still interesting that only python3 seems to have an issue with it… With some silly explicit if-else assigning we can sidestep this issue while retaining the same output for 99.99% of all users (= noone actually configures additional compression algorithms which are also provided by repositories…), but even for these 0.01% its just a small change in the display as Mode can not be used for anything else. Example: apt/aptitude uses it in its 'update' implementations in the one-line progress at the bottom for specific items. Closes: 781858
2015-04-07properly handle expected filesize in httpsDavid Kalnischkies
The worker expects that the methods tell him when they start or finish downloading a file. Various information pieces are passed along in this report including the (expected) filesize. https is using a "global" struct for reporting which made it 'reuse' incorrect values in some cases like a non-existent InRelease fallbacking to Release{,.gpg} resulting in an incorrect size-mismatch warning scaring and desensitizing users as well as being subject to a race between the write_data and progress callbacks generating incorrect progress reporting and potentially the same error message. Other branches as well as the bugreports contain 'better' fixes making the struct local and other sensible changes, but are larger as a result, so in this version we opted for short diff with minimal effect above else instead. Closes: 777565, 781509 Thanks: Robert Edmonds and Anders Kaseorg for initial patchs

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

2015-03-16test exitcode as well as string equalityDavid Kalnischkies
We use test{success,failure} now all over the place in the framework, so its only consequencial to do this in the situations in which we test for a specific output as well. Git-Dch: Ignore
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
2015-03-16set version before updating po filesDavid Kalnischkies
This way the 'correct' version is carried over into the po files to reflect which version they were built for rather than the version before the current one. Git-Dch: Ignore
2015-03-16(error) Same iterator is used with different containersDavid Kalnischkies
cppcheck reports this error, its not really a problem for us as the API can actually deal with it via implicit conversion, but being explicit can't hurt and the less reported errors the better. Git-Dch: Ignore

2015-03-16properly implement pkgRecord::Parser for *.deb filesDavid Kalnischkies
Implementing FileName() works for most cases for us, but other frontends might need more and even for us its not very stable as the normal Jump() implementation is pretty bad on a deb file and produce errors on its own at times. So, replacing this makeshift with a complete implementation by mostly just shuffling code around.
2015-03-16fix another d(e)select-upgrade typoDavid Kalnischkies

2015-03-16derive more of https from http methodDavid Kalnischkies
Bug #778375 uncovered that https wasn't properly integrated in the class family tree of http as it was supposed to be leading to a NULL pointer dereference. Fixing this 'properly' was deemed to much diff for practically no gain that late in the release, so commit 0c2dc43d4fe1d026650b5e2920a021557f9534a6 just fixed the synptom, while this commit here is fixing the cause plus adding a test.

2015-01-10award points for positive dependencies againDavid Kalnischkies
Commit 9ec748ff103840c4c65471ca00d3b72984131ce4 from Feb 23 last year adds a version check after 8daf68e366fa9fa2794ae667f51562663856237c added 8 days earlier negative points for breaks/conflicts with the intended that only dependencies which are satisfied propagate points (aka: old conflicts do not). The implementation was needlessly complex and flawed through preventing positive dependencies from gaining points like they did before these commits making library transitions harder instead of simpler. It worked out anyhow most of the time out of pure 'luck' (and other ways of gaining points) or got miss attributed to being a temporary hick-up. Closes: 774924
2015-01-10128 KiB DSC files ought to be enough for everyoneDavid Kalnischkies
Your mileage may vary, but don't worry: There is more than one way to do it, but our one size fits all is not a bigger hammer, but an entire roundhouse kick! So brace yourself for the tl;dr: The limit is gone.* Beware: This fixes also the problem that a double newline is unconditionally added 'later' which is an overcommitment in case the dsc filesize is limit-2 <= x <= limit. * limited to numbers fitting into an unsigned long long. Closes: 774893
2015-01-06Add regression test for the previous commitMichael Vogt
The issue was that https.cc never called URIStart(), one way to detect this is that no download progress is generated without this call. The test now checks for this and as a side-effect will also ensure that we do not break download progress reporting and Acquire::{http,https}::Dl-Limit accidently.
2015-01-05Fix missing URIStart() for https downloadsMichael Vogt
Add a explicit ReceivedData to HttpsMethod that indicates when we got data from the connection so that we can send URISTart() to the parent. This is needed because URIStart got moved in f9b4f12d from the progress_callback to write_data() and it only checks for Res.Size. In the old code if progress_callback is called by libcurl (and sets Res.Size) before write_data is called then URIStart() is never send. Making this a explicit ReceivedData variable fixes this issue.
