2016-06-22better error message for insufficient hashsumsDavid Kalnischkies
Downloading and saying "Hash Sum mismatch" isn't very friendly from a user POV, so with this change we try to detect such cases early on and report it, preferably before download even started. Closes: 827758
2016-06-22source: if download is skipped, don't try to unpackDavid Kalnischkies
If apt decides it can't download a file it is relatively pointless to try to tell dpkg-source to unpack it.
2016-06-22forbid insecure repositories by default expect in apt-getDavid Kalnischkies
With this commit all APT-based clients default to refusing to work with unsigned or otherwise insufficently secured repositories. In terms of apt and apt-get this changes nothing, but it effects all tools using libapt like aptitude, synaptic or packagekit. The exception remains apt-get for stretch for now as this might break too many scripts/usecases too quickly. The documentation is updated and extended to reflect how to opt out or in on this behaviour change. Closes: 808367
2016-06-22generalize secure->insecure downgrade protectionDavid Kalnischkies
Handling the extra check (and force requirement) for downgrades in security in our AllowInsecureRepositories checker helps in having this check everywhere instead of just in the most common place and requiring a little extra force in such cases is always good.
2016-06-22handle weak-security repositories as unauthenticatedDavid Kalnischkies
APT can be forced to deal with repositories which have no security features whatsoever, so just giving up on repositories which "just" fail our current criteria of good security features is the wrong incentive. Of course, repositories are better of fixing their setup to provide the minimum of security features, but sometimes this isn't possible: Historic repositories for example which do not change (anymore). That also fixes problem with repositories which are marked as trusted, but are providing only weak security features which would fail the parsing of the Release file. Closes: 827364
2016-06-22run update post-invokes even on (partial) failuresDavid Kalnischkies
Unsecure repositories result in error messages by default which causes the acquire run to fail hard, but non-failing repositories are still updated just like in the slightly less hard-failures which got this behaviour in 35664152e47a1d4d712fd52e0f0a2dc8ed359d32.

Reinstate caching of file hashes in apt-ftparchive
2016-06-20Check for cached hash entries to determine which (if any) hash typesDominic Benson
need to be generated for the current file. In 1.0.9, each hash type was handled by a separate method, each of which checked the cache. It looks like when these code paths were unified (in a311fb96b84757ef8628e6a754232614a53b7891) the cache checks were not incorporated into the new method.
2016-06-20implement and document DIRECT for auto-detect-proxyDavid Kalnischkies
There is a subtile difference between an empty setting and "DIRECT" in the configuration as the later overrides the generic settings while the earlier does not. Also, non-zero exitcodes should really be reported as an error rather than silently discarded.
2016-06-20do not error if auto-detect-proxy cmd has no outputDavid Kalnischkies
Regression introduced in 8f858d560e3b7b475c623c4e242d1edce246025a. Commands are probably better of always having output through as the fall through to the generic proxy settings is likely not intended. As documenting and implementing this more consistently is kind of a regression through, it is split off into the next commit. Closes: 827713
2016-06-17avoid std::get_time usage to sidestep libstdc++6 bugDavid Kalnischkies
As reported upstream in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71556 the implementation of std::get_time is currently not as accepting as strptime is, especially in how hours should be formatted. Just reverting 9febc2b238e1e322dce1f94ecbed46d595893b52 would be possible, but then we would reopen the problems fixed by it, so instead I opted here for a rewrite of the parsing logic which makes this method a lot longer, but at least it provides the same benefits as the rewrite in std::get_time was intended to give us and decouples us from the fix of the issue in the standard library implementation of GCC. LP: 1593583
2016-06-17merge sources.list lines based on Release filenameDavid Kalnischkies
Merging by URI means that having sources lines with different URI methods results in 'strange' warning and error messages, which aren't very friendly from a user point of view as not encoding the method in the filename is effectivly an implementation detail. Merging by filename removes these messages and makes everything "work" even if it isn't working the way it is configured as the indexes aren't acquired over the method given, but over the first method for this release file (which argueably is an implementation detail stemming from the filename encoding, too). So either direction isn't perfectly "right", but personally I prefer "magic" over strange error messages (and doing a full-circle detection of this with its own messages which would need to be translated feels like way too much effort for dubious gain). Closes: 826944
2016-06-15http: don't hang on redirect with length + connection closeDavid Kalnischkies
Most servers who close the connection do not send a content-length as this is redundant information usually, but some might and while testing with our server and with 'aptwebserver::response-header::Connection' set to 'close' I noticed that http hangs after a redirect in such cases, so if we have the information, just use it instead of discarding it.
2016-06-14don't use FindFile for external Dir::Bin commandsDavid Kalnischkies
We usually use absolute paths to specific the location of dpkg, apt-key and the like, but there is nothing wrong with using just the command name and instead let exec(3) make the lookup in PATH. We had a wild mixture before, so opting for the more accepting option out of the two seems about right especially as it makes no difference in the default case as apt uses absolute paths.

2016-06-10don't leak FD in AutoProxyDetect command return parsingDavid Kalnischkies
Just closing the fd would be enough, but while we are at it we can also use the Popen interface to have an easier time with this.
2016-06-10don't leak dpkg statusfd pipe in debuggingDavid Kalnischkies
Not a big deal to leak fds in debugging mode, but for completeness. Git-Dch: Ignore
2016-06-10don't leak EDSP solver output fdDavid Kalnischkies
2016-06-10don't leak an FD in lz4 (de)compressionDavid Kalnischkies
Seen first in #826783, but as this buglog also shows leaked uncompressed files as well we don't close it just yet.
2016-06-10do not hang on piped input in PipedFileFdPrivateDavid Kalnischkies
This effects only compressors configured on the fly (rather then the inbuilt ones as they use a library).
2016-06-09remove racy_pselect fallbackDavid Kalnischkies
The comment says it should have been removed with Lenny+1 which is a small while ago already, so it seems like a good time now… And as this is a cleanup commit it also gets right of spurious whitespace at the end of lines, adds missing fold markers and similar busy work. Git-Dch: Ignore
2016-06-08drop Dpkg::MaxArgs in favor of Dpkg::MaxArgsBytesDavid Kalnischkies
We had an old FIXME saying that it is probably pointless to do this if we limit by length of the commandline already and I completely agree. The splitting is bad enough if it must be done, so we should only do it if we have to (as in absolute length of commandline) and, but that is just a remark, it is unlikely that we ever have/had a call triggering this as the default value was ~32000 items…
2016-06-08don't explicitly configure the last round of packagesDavid Kalnischkies
We end our operation by calling "dpkg --configure -a", so instead of running a (big) configure run with all packages mentioned explicitly before this, we simply skip them and let them be handled by this call implicitly. There isn't really an observeable gain to be had here from a speed point, but it helps in avoiding an (uncommon) problem of having a too long commandline passed to dpkg, which we would split up (probably incorrectly).
2016-06-08edsp: drop privileges before executing solversDavid Kalnischkies
Most (if not all) solvers should be able to run perfectly fine without root privileges as they get the entire state they are supposed to work on via stdin and do not perform any action directly, but just pass suggestions on via stdout. The new default is to run them all as _apt hence, but each solver can configure another user if it chooses/must. The security benefits are minimal at best, but it helps preventing silly mistakes (see 35f3ed061f10a25a3fb28bc988fddbb976344c4d) and that is always good. Note that our 'apt' and 'dump' solver already dropped privileges if they had them.
2016-06-08edsp: if logging is requested, do it for internal, tooDavid Kalnischkies
Create and log the EDSP(like) request even if we use the internal resolver.
2016-06-08edsp: if internal is used, keep this decisionDavid Kalnischkies
It wasn't noticeable before, but now with the (optional) logging it can be observed that we decide in the internal path two times if an internal or external solver should be used (and hence with logging, it is attempted twice), so if we are in the internal path call the internal resolver directly, which means those internal methods need to be public – but we can hide them based on the symbol at least.
2016-06-08move 'dump' solver from apt-utils to apt packageDavid Kalnischkies
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
2016-06-06get right of the hardcoded string-length comparesDavid Kalnischkies
With have better ways to compare, manipulate and work with strings, so use it instead of counting string length by hand with is a wonder it hasn't failed yet. Ignoreable from a changelog perspective as there is no behaviour change. 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
2016-06-04prepare-release: ignore newer version symbolsDavid Kalnischkies
The script takes the version from the changelog, but if it lacks behind and the symbols file already includes symbols tagged for the next version the helper prints incorrect lines as NEW for these symbols, but ideally it shouldn't print them at all as the symbol is already dealt with. Git-Dch: Ignore

2016-06-04edsp: use a stanza based interface for solution writingDavid Kalnischkies
EDSP had a WriteSolution method to write out the entire solution based on the inspection of a given pkgDepCache, but that is rather inflexible both for EDSP itself and for other EDSP like-protocols. It seems better to use a smaller scope in printing just a single stanza based on a given version as there is more reuse potential.
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.
2016-06-02apt-key: change to / before find to satisfy its CWD needsDavid Kalnischkies
First seen on hurd, but easily reproducible on all systems by removing the 'execution' bit from the current working directory and watching some tests (mostly the no-output expecting tests) fail due to find printing: "find: Failed to restore initial working directory: …" Samuel Thibault says in the bugreport: | To do its work, find first records the $PWD, then goes to | /etc/apt/trusted.gpg.d/ to find the files, and then goes back to $PWD. | | On Linux, getting $PWD from the 700 directory happens to work by luck | (POSIX says that getcwd can return [EACCES]: Search permission was denied | for the current directory, or read or search permission was denied for a | directory above the current directory in the file hierarchy). And going | back to $PWD fails, and thus find returns 1, but at least it emitted its | output. | | On Hurd, getting $PWD from the 700 directory fails, and find thus aborts | immediately, without emitting any output, and thus no keyring is found. | | So, to summarize, the issue is that since apt-get update runs find as a | non-root user, running it from a 700 directory breaks find. Solved as suggested by changing to '/' before running find, with some paranoia extra care taking to ensure the paths we give to find are really absolute paths first (they really should, but TMPDIR=. or a similar Dir::Etc::trustedparts setting could exist somewhere in the wild). The commit takes also the opportunity to make these lines slightly less error ignoring and the two find calls using (mostly) the same parameters. Thanks: Samuel Thibault for 'finding' the culprit! Closes: 826043
2016-06-02ignore std::locale exeception on non-existent "" localeDavid Kalnischkies
In 8b79c94af7f7cf2e5e5342294bc6e5a908cacabf changing to usage of C++ way of setting the locale causes us to be terminated in case of usage of an ungenerated locale as LC_ALL (or similar) – but we don't want to fail here, we just want to carry on as before with setlocale which we call in that case just for good measure.
2016-06-01Pass -fvisibility-inlines-hidden to g++Julian Andres Klode
This reduces the number of symbols by about 10%. Unfortunately, it does not seem to cover all the weird std::vector and friend template expansions. ABI should not brake due to that change: It was never specified before whether an inline symbol was exported or not; so no library could rely on its presence. Instead, the symbols were exported in each library/program needing it and and then merged into a common one by the dynamic linker. Also update the symbol files to account for the removed symbols.

2016-05-29try to detect sudo spawned root-shell in prefixingDavid Kalnischkies
It is a try as the we need to inspect SUDO_COMMAND which could be anything – apt, apt-get, in /usr/bin, in a $DPKG_ROOT "chroot", build from source, aliases, … The best we can do is look if the SHELL variable is equal to the SUDO_COMMAND which would mean a shell was invoked. That isn't fail-safe if different shells are involved as sub-shells have the tendency of not overriding the SHELL so a bash started from within zsh can happily pretend to be still zsh, so we could have a look at /etc/shells for a list, but oh well, we have to stop somewhere I guess. This sudo-prefixing feature is a gimmick after all. Closes: 825742
2016-05-28travis: use gcc-5 instead of gcc(-4.9)David Kalnischkies
The std::put_time and std::get_time introduced in 9febc2b238e1e322dce1f94ecbed46d595893b52 are part of C++11, but not implemented in GCC until version 5. std::put_time could actually be worked around via using the facets put() directly, but get() isn't implemented so that doesn't really help. We require various tools from wily (which also means we can't build apt on Debian stable) already, so requiring gcc-5 is just one more instead of a big step [and an ignoreable change for changelog anyhow]. It also helps in testing what will actually be used (in terms of the c++11 std ABI) instead of the old ABI. Git-Dch: Ignore
2016-05-28look into the right textdomain for apt-utils againDavid Kalnischkies
Broken in e7e10e47476606e3b2274cf66b1e8ea74b236757 by looking always into "apt" while we ship some tools in "apt-utils"…
2016-05-28use std::locale::global instead of setlocaleDavid Kalnischkies
We use a wild mixture of C and C++ ways of generating output, so having a consistent world-view in both styles sounds like a good idea and should help in preventing regressions.

2016-05-28avoid changing the global LC_TIME for Release writingDavid Kalnischkies
Using C++ here avoids calling setlocale here which never really was that ideal, but needed to avoid locale specific weekday/month names.
2016-05-28accept only the expected UTC timezones in date parsingDavid Kalnischkies
HTTP/1.1 hardcodes GMT (RFC 7231 §7.1.1.1) and what is good enough for the internet must be good enough for us™ as we reuse the implementation internally to parse (most) dates we encounter in various places like the Release files with their Date and Valid-Until header fields. Implementing a fully timezone aware parser just feels too hard for no effective benefit as it would take 5+ years (= until LTS's are out of fashion) until a repository could use non-UTC dates and expect it to work. Not counting non-apt implementations which might or might not only want to encounter UTC here as well. As a bonus, this eliminates the use of an instance of setlocale in libapt. Closes: 819697
