2016-07-30prevent C++ locale number formatting in text APIs (try 2)David Kalnischkies
Followup of b58e2c7c56b1416a343e81f9f80cb1f02c128e25. Still a regression of sorts of 8b79c94af7f7cf2e5e5342294bc6e5a908cacabf. Closes: 832044
2016-07-29edsp: try to read responses even if writing failedDavid Kalnischkies
If a solver/planner exits before apt is done writing we will generate write errors. Solvers like 'dump' can be pretty quick in failing but produce a valid EDSP error report apt should read, parse and display instead of just discarding even through we had write errors.
2016-07-29if the FileFd failed already following calls should fail, tooDavid Kalnischkies
There is no point in trying to perform Write/Read on a FileFd which already failed as they aren't going to work as expected, so we should make sure that they fail early on and hard.

2016-07-27eipp: avoid producing file warnings in simulationDavid Kalnischkies
Simulations are frequently run by unprivileged users which naturally don't have the permissions to write to the default location for the eipp file. Either way is bad as running in simulation mode doesn't mean we don't want to run the logging (as EIPP runs the same regardless of simulation or 'real' run), but showing the warnings is relatively pointless in the default setup, so, in case we would produce errors and perform a simulation we will discard the warnings and carry on. Running apt with an external planner wouldn't have generated these messages btw. Closes: 832614
2016-07-27rred: truncate result file before writing to itDavid Kalnischkies
If another file in the transaction fails and hence dooms the transaction we can end in a situation in which a -patched file (= rred writes the result of the patching to it) remains in the partial/ directory. The next apt call will perform the rred patching again and write its result again to the -patched file, but instead of starting with an empty file as intended it will override the content previously in the file which has the same result if the new content happens to be longer than the old content, but if it isn't parts of the old content remain in the file which will pass verification as the new content written to it matches the hashes and if the entire transaction passes the file will be moved the lists/ directory where it might or might not trigger errors depending on if the old content which remained forms a valid file together with the new content. This has no real security implications as no untrusted data is involved: The old content consists of a base file which passed verification and a bunch of patches which all passed multiple verifications as well, so the old content isn't controllable by an attacker and the new one isn't either (as the new content alone passes verification). So the best an attacker can do is letting the user run into the same issue as in the report. Closes: #831762
2016-07-27http: skip requesting if pipeline is fullDavid Kalnischkies
The rewrite in 742f67eaede80d2f9b3631d8697ebd63b8f95427 is based on the assumption that the pipeline will always be at least one item short each time it is called, but the logs in #832113 suggest that this isn't always the case. I fail to see how at the moment, but the old implementation had this behavior, so restoring it can't really hurt, can it?
2016-07-27use proper warning for automatic pipeline disableDavid Kalnischkies
Also fixes message itself to mention the correct option name as noticed in #832113.
2016-07-26verify hash of input file in rredDavid Kalnischkies
We read the entire input file we want to patch anyhow, so we can also calculate the hash for that file and compare it with what he had expected it to be. Note that this isn't really a security improvement as a) the file we patch is trusted & b) if the input is incorrect, the result will hardly be matching, so this is just for failing slightly earlier with a more relevant error message (althrough, in terms of rred its ignored and complete download attempt instead).
2016-07-23call flush on the wrapped writebuffered FileFdDavid Kalnischkies
The flush call is a no-op in most FileFd implementations so this isn't as critical as it might sound as the only non-trivial implementation is in the buffered writer, which tends not be used to buffer another buffer…
2016-07-22report progress for triggered actionsDavid Kalnischkies
APT doesn't know which packages will be triggered in the course of actions, so it can't plan to see them for progress beforehand, but if it sees that dpkg says that a package was triggered we can add additional states. This is pretty much magic – after all it sets back the progress – and there are cornercases in which this will result in incorrect totals (package in partial states may or may not loose trigger states), but the worst which can happen is that the progress is slightly incorrect and doesn't reach 100%, but so be it. Better than being stuck at 100% for a while as apt isn't realizing that a bunch of triggers still need to be processed.
2016-07-22use a configurable location for apport report storageDavid Kalnischkies
Hardcoding /var/crash means we can't test it properly and it isn't really our style.
2016-07-22report progress for removing while purging pkgsDavid Kalnischkies
The progress reporting for a package sheduled for purging only included the states dpkg passes through while actually purging the package – if the package was fully installed before dpkg will pass first through all remove states before purging it, so in the interest of consistent reporting our progress reporting should do that, too.

2016-07-22create non-existent files in edit-sources with 644 instead of 640David Kalnischkies
If the sources file we want to edit doesn't exist yet GetLock will create it with 640, which for a generic lockfile might be okay, but as this is a sources file more relaxed permissions are in order – and actually required as it wont be readable for unprivileged users causing warnings/errors in apt calls. Reported-By: J. Theede (musca) on IRC
2016-07-22report warnings&errors consistently in edit-sourcesDavid Kalnischkies
After editing the sources it is a good idea to (re)built the caches as they will be out-of-date and doing so helps in reporting higherlevel errors like duplicates sources.list entries, too, instead of just general parsing errors as before.

Closes: 832039
2016-07-22tests: avoid time-dependent rebuild of cachesDavid Kalnischkies
The tests changes the sources.list and the modification time of this file is considered while figuring out if the cache can be good. Usually this isn't an issue, but in that case we have the cache generation produce warnings which appear twice in this case. Gbp-Dch: Ignore
2016-07-22clean up default-stanzas from extended_states on writeDavid Kalnischkies
The existing cleanup was happening only for packages which had a status change (install -> uninstalled) which is the most frequent but no the only case – you can e.g. set autobits explicitly with apt-mark. This would leave stanzas in the states file declaring a package to be manually installed – which is the default value for a package not listed at all, so we can just as well drop it from the file.
2016-07-22tests: skip over -flags for first option in autotestsDavid Kalnischkies
Otherwise calls like "apt -q install" end up calling "aptautotest_apt_q" instead of "aptautotest_apt_install" Gbp-Dch: Ignore
2016-07-22support "install ./foo.changes"David Kalnischkies
We support installing ./foo.deb (and ./foo.dsc for source) for a while now, but it can be a bit clunky to work with those directly if you e.g. build packages locally in a 'central' build-area. The changes files also include hashsums and can be signed, so this can also be considered an enhancement in terms of security as a user "just" has to verify the signature on the changes file then rather than checking all deb files individually in these manual installation procedures.
2016-07-22allow arch=all to override No-Support-for-Architecture-allDavid Kalnischkies
If a user explicitly requests the download of arch:all apt shouldn't get in the way and perform its detection dance if arch:all packages are (also) in arch:any files or not. This e.g. allows setting arch=all on a source with such a field (or one which doesn't support all at all, but has the arch:all files like Debian itself ATM) to get only the arch:all packages from there instead of behaving like a no-op.

2016-07-19don't hardcode /var/lib/dpkg/status as dir::state::statusDavid Kalnischkies
Theoretically it should be enough to change the Dir setting and have apt pick the dpkg/status file from that. Also, it should be consistently effected by RootDir. Both wasn't really the case through, so a user had to explicitly set it too (or ignore it and have or not have expected sideeffects caused by it). This commit tries to guess better the location of the dpkg/status file by setting dir::state::status to a naive "../dpkg/status", just that this setting would be interpreted as relative to the CWD and not relative to the dir::state directory. Also, the status file isn't really relative to the state files apt has in /var/lib/apt/ as evident if we consider that apt/ could be a symlink to someplace else and "../dpkg" not effected by it, so what we do here is an explicit replace on apt/ – similar to how we create directories if it ends in apt/ – with dpkg/. As this is a change it has the potential to cause regressions in so far as the dpkg/status file of the "host" system is no longer used if you set a "chroot" system via the Dir setting – but that tends to be intended and causes people to painfully figure out that they had to set this explicitly before, so that it now works more in terms of how the other Dir settings work (aka "as expected"). If using the host status file is really intended it is in fact easier to set this explicitely compared to setting the new "magic" location explicitely.
2016-07-19ensure Cnf::FindFile doesn't return files below /dev/nullDavid Kalnischkies
Very unlikely, but if the parent is /dev/null, the child empty and the grandchild a value we returned /dev/null/value which doesn't exist, so hardly a problem, but for best operability we should be consistent in our work and return /dev/null always.
2016-07-15tests: activate dpkg multi-arch even if test is single archDavid Kalnischkies
Most tests are either multiarch, do not care for the specific architecture or do not interact with dpkg, so really effect by this is only test-external-installation-planner-protocol, but its a general issue that while APT can be told to treat any architecture as native dpkg has the native architecture hardcoded so if we run tests we must make sure that dpkg knows about the architecture we will treat as "native" in apt as otherwise dpkg will refuse to install packages from such an architecture. This reverts f883d2c3675eae2700e4cd1532c1a236cae69a4e as it complicates the test slightly for no practical gain after the generic fix.

Hardcoding amd64 broke the tests.

2016-07-08Add kernels with "+" in the package name to APT::NeverAutoRemoveAndrew Patterson

2016-07-06keep trying with next if connection to a SRV host failedDavid Kalnischkies
Instead of only trying the first host we get via SRV, we try them all as we are supposed to and if that isn't working we try to connect to the host itself as if we hadn't seen any SRV records. This was already the intend of the old code, but it failed to hide earlier problems for the next call, which would unconditionally fail then resulting in an all around failure to connect. With proper stacking we can also keep the error messages of each call around (and in the order tried) so if the entire connection fails we can report all the things we have tried while we discard the entire stack if something works out in the end.
2016-07-06report all instead of first error up the acquire chainDavid Kalnischkies
If we don't give a specific error to report up it is likely that all error currently in the error stack are equally important, so reporting just one could turn out to be confusing e.g. if name resolution failed in a SRV record list.
2016-07-06don't change owner/perms/times through file:// symlinksDavid Kalnischkies
If we have files in partial/ from a previous invocation or similar such those could be symlinks created by file:// sources. The code is expecting only real files through and happily changes owner, modification times and permission on the file the symlink points to which tend to be files we have no business in touching in this way. Permissions of symlinks shouldn't be changed, changing owner is usually pointless to, but just to be sure we pick the easy way out and use lchown, check for symlinks before chmod/utimes. Reported-By: Mattia Rizzolo on IRC
2016-07-05tests: disable EIPP logging in test-compressed-indexesDavid Kalnischkies
The test makes heavy use of disabling compression types which are usually available some way or another like xz which is how the EIPP logs are compressed by default. Instead of changing this test to change the filename according to the compression we want to test we just disable EIPP logging for this test as that is easier and has the same practical effect. Gbp-Dch: Ignore
2016-07-05EIPP/EDSP log can't be written is a warning, not an errorDavid Kalnischkies
If other logs can't be written this is a warning to, so for consistency sake translate the errors to warnings.
2016-07-05report write errors in EDSP/EIPP properly back to callerDavid Kalnischkies
Unlikely to happen in practice and I wonder more how I could miss these in earlier reviews, but okay, lets fix it for consistency now.
2016-07-05give a descriptive error for pipe tries with 'false'David Kalnischkies
If libapt has builtin support for a compression type it will create a dummy compressor struct with the Binary set to 'false' as it will catch these before using the generic pipe implementation which uses the Binary. The catching happens based on configured Names through, so you can actually force apt to use the external binaries even if it would usually use the builtin support. That logic fails through if you don't happen to have these external binaries installed as it will fallback to calling 'false', which will end in confusing 'Write error's. So, this is again something you only encounter in constructed testing. Gbp-Dch: Ignore
2016-07-05don't add default compressors two times if disabledDavid Kalnischkies
This is in so far pointless as the first match will deal with the extension, so we don't actually ever use these second instances – probably for the better as most need arguments to behave as epected & more importantly: the point of the exercise disabling their use for testing proposes. Gbp-Dch: Ignore
2016-07-05use the right key for compressor configuration dumpDavid Kalnischkies
The generated dump output is incorrect in sofar as it uses the name as the key for this compressor, but they don't need to be equal as is the case if you force some of the inbuilt ones to be disabled as our testing framework does it at times. This is hidden from changelog as nobody will actually notice while describing it in a few words make it sound like an important change… Git-Dch: Ignore

2016-07-02use +0000 instead of UTC by default as timezone in outputDavid Kalnischkies
All apt versions support numeric as well as 3-character timezones just fine and its actually hard to write code which doesn't "accidently" accepts it. So why change? Documenting the Date/Valid-Until fields in the Release file is easy to do in terms of referencing the datetime format used e.g. in the Debian changelogs (policy §4.4). This format specifies only the numeric timezones through, not the nowadays obsolete 3-character ones, so in the interest of least surprise we should use the same format even through it carries a small risk of regression in other clients (which encounter repositories created with apt-ftparchive). In case it is really regressing in practice, the hidden option -o APT::FTPArchive::Release::NumericTimezone=0 can be used to go back to good old UTC as timezone. The EDSP and EIPP protocols use this 'new' format, the text interface used to communicate with the acquire methods does not for compatibility reasons even if none of our methods would be effected and I doubt any other would (in these instances the timezone is 'GMT' as that is what HTTP/1.1 requires). Note that this is only true for apt talking to methods, (libapt-based) methods talking to apt will respond with the 'new' format. It is therefore strongly adviced to support both also in method input.
2016-07-02deprecate 'apt-key update' and no-op it in DebianDavid Kalnischkies
Debian isn't using 'update' anymore for years and the command is in direct conflict with our goal of not requiring gnupg anymore, so it is high time to officially declare this command as deprecated.
2016-07-01warn if apt-key is used in scripts/its output parsedDavid Kalnischkies
apt-key needs gnupg for most of its operations, but depending on it isn't very efficient as apt-key is hardly used by users – and scripts shouldn't use it to begin with as it is just a silly wrapper. To draw more attention on the fact that e.g. 'apt-key add' should not be used in favor of "just" dropping a keyring file into the trusted.gpg.d directory this commit implements the display of warnings.
2016-07-01alias apt-key list to fingerDavid Kalnischkies
There is no real point in having two commands which roughly do the same thing, especially if the difference is just in the display of the fingerprint and hence security sensitive information. Closes: 829232
