2017-01-19make the moo reproducibleDavid Kalnischkies
Normal cows moo every time they feel like it and it might be a "moo", "moo!" or "moo?". This is completely unacceptable behaviour in our super cow through as as a superior being it has to show its superiority over the common cows and the meager easter eggs by being fully reproducible! The second version of Chris' patch is modified to include an array of tests for this feature – which doubles as explanation for some of the moo lines by giving more exact dates – and falling back to current time if the environment is invalid + passing time around instead of having an invalid environment be an unrecoverable error (aka: Guru Meditation) as that is more inline with how apt usually behaves: The wisdom of super cow should be available to everyone, even to the most misfortune users not capable of having a valid environment variable. That makes the code slightly more ugly, so instead of requiring a young follower to produce a third version a high priest of the cult applied the finishing touches as he is used to the pain by now – and another round with the slowpoke high priest would have been a serious threat to the Debian release schedule which the cow would not approve. Closes: #848721 Signed-off-by: Super Cow Thanks: Chris Lamb for initial patch and guru meditation
2017-01-19fix 'install --no-download' modeDavid Kalnischkies
The mode wasn't working at all if not used together with --fix-missing which while likely to come in pairs its legal to use standalone. Regression-in: eb1f04dda07c2b69549ad9fd793cca0e91841b3e
2017-01-19don't lock dpkg in update commandsDavid Kalnischkies
The update command acquires a lock on lists/, but at the end it will also require the dpkg/lock while building the binary caches. That seems rather pointless as we are only reading those files, not causing writing in them. This can also cause problems if a package installation is running and a background process (like cron) starts an update: If you are "lucky" enough the update process will pick the dpkg lock in between apt calls causing the installation process to fail.
2017-01-19don't lock dpkg in 'apt-get clean'David Kalnischkies
We get the archives/lock for clean – that is enough to ensure that other apt instances aren't interfering (or are being interfered with). We don't need to block actions involving dpkg.
2017-01-19don't show update stats if cache generation is disabledDavid Kalnischkies
Unlikely that anyone is actually running into this, but if we asked to not generate a cache and avoid it in the first step we shouldn't create one implicitly anyway by displaying the statistics.
2017-01-17CMake: Document that the globs are expanded during CMakeJulian Andres Klode
This will avoid people from thinking that they have to do nothing when they change the set of files. Gbp-Dch: ignore
2016-12-31allow warning generation for non-whitelisted optionsDavid Kalnischkies
The idea is simple: Each¹ Find*( call starts with a call check if the given option (with the requested type) exists in the whitelist. The whitelist is specified via our configure-index file so that we have a better chance at keeping it current. the whitelist is loaded via a special (undocumented for now) configuration stanza and if none is loaded the empty whitelist will make it so that no warnings are shown. Much needs to be done still, but that is as good a time as any to take a snapshot of the current state and release it into the wild given that it found some bugs already and has no practical effect on users. ¹ not all in this iteration, but many
2016-12-31use FindB instead of FindI for Debug::pkgAutoRemoveDavid Kalnischkies
Again no practical difference, but for consistency a boolean option should really be accessed via a boolean method rather than an int especially if you happen to try setting the option to "true" … Gbp-Dch: Ignore
2016-12-31expand -f to --fix-broken in error messagesDavid Kalnischkies
Users end up believing that this is a --force mode as -f is common for that, but apt doesn't have such a mode and --fix-broken is really not about forcing something but actually trying to fix the breakage which tends to be the result of a user forcing something on its system via low-level forced dpkg calls. Example: The "common" pattern of "dpkg -i ./foo.deb; apt install -f" is nowadays far better dealt with via "apt install ./foo.deb". And while at it the two places handing out this suggestion are changed to use the same strings to avoid needless translation work in the future and the suggestion uses 'apt' instead of 'apt-get' as this will be run interactively by a user, so its a good opportunity to showcase what we can do and will allow us to be more helpful to the user. Closes: #709092 Thanks: Kristian Glass for initial patch!
2016-12-31allow default build-essentials to be overriddenDavid Kalnischkies
The config list APT::Build-Essential gets a similar treatment to other lists now by having the value of the option itself be an override for the list allowing to disable build-essentials entirely as well as adding/overriding as usual by now in other lists. Reported-By: Johannes 'josch' Schauer on IRC
2016-12-31add --indep-only for build-dep commandDavid Kalnischkies
The implementation is quite different compared to --arch-only due to ABI reasons but functionality wise they are similar and usually both available for symmetry at least. Closes: #845775
2016-12-16default to --no-check for dpkg-source callDavid Kalnischkies
In bug #757534 the opposite direction was initially requested, but what we did end up with was having a possibility to configure the options passed to dpkg. The reasoning given their and in #724744 is specific why apt doesn't need the checks to be performed by dpkg. In fact, what these two reports show is that if those checks are run people end up being confused about the requirement of them being run, so given the best case those checks can do is do nothing (visibly) while the worst cases are warnings and errors which are neither we are from a security point better of with disabling them – as (as mentioned in the bugreports) false positives for issues are really really bad in a security context. Closes: 724744
2016-12-16remove needless fork() in apt-get sourceDavid Kalnischkies
We are calling system() in this code paths, so all we do here is having a single child performing the action while the parent waits for it to finish… with the added strangeness of not having our usual error message collection and giving up after first failure even if told to act on multiple packages.
2016-12-16let {dsc,tar,diff}-only implicitly enable download-onlyDavid Kalnischkies
That was the case already for tar-only and diff-only, but in a more confusing way and without a message while dsc "worked" before resulting in a dpkg-source error shortly after as tar/diff files aren't available…
2016-11-09add support for Build-Depends/Conflicts-ArchJohannes Schauer
These new enum values might cause "interesting" behaviour in tools not expecting them – like an old apt would think a Build-Conflicts-Arch is some sort of Build-Depends – but that can't reasonably be avoided and effects only packages using B-D/C-A so if there is any breakage the tools can easily be adapted. The APT_PKG_RELEASE number is increased so that libapt users can detect the availability of these new enum fields via: #if APT_PKG_ABI > 500 || (APT_PKG_ABI == 500 && APT_PKG_RELEASE >= 1) Closes: #837395
2016-11-02don't install new deps of candidates for kept back pkgsDavid Kalnischkies
In effect this is an extension of the 6 years old commit a8dfff90aa740889eb99d00fde5d70908d9fd88a which uses the autoremover to remove packages again from the solution which are no longer needed to be there. Commonly these are dependencies of packages we end up not installed due to problem resolver decisions. Slightly less common is the situation we deal with here: a package which we wanted to upgrade sporting a new dependency, but ended up holding back. The problem is that all versions of an installed reverse dependencies can bring back a "garbage" package – we need to do this as there is nothing inherently wrong in having garbage packages installed or upgrade them, which itself would have garbage dependencies, so just blindly killing all new garbage packages would prevent the upgrade (and actually generate errors). What we should be doing is looking only at the version we will have on the system, disregarding all old/new reverse dependencies. Reported-By: Stuart Prescott (themill) on IRC
2016-09-07edsp: try 2 to read responses even if writing failedDavid Kalnischkies
Commit b60c8a89c281f2bb945d426d2215cbf8f5760738 improved the situation, but due to inconsistency mostly for planners, not for solvers. As the idea of hiding errors if we show another error is a bit scary (as the extern error might be a followup of our intern error, rather than the reason for our intern error as it is at the moment) we don't discard the errors, but if we got an extern error we show them directly removing them from the error list at the end of the run – that list will contain the extern error which hopefully gives us the best of both worlds. The problem itself is the same as before: The externals exiting before apt is done talking to them. Reported-By: Johannes 'josch' Schauer on IRC
2016-08-27Merge branch 'portability/freebsd'Julian Andres Klode
2016-08-26Accept --autoremove as alias for --auto-removeJulian Andres Klode
I probably missed that when I did the usability work. But better late than never.
2016-08-26CMake/private-download: Fix statfs includes on FreeBSDJulian Andres Klode
On FreeBSD, we have to include sys/params.h and sys/mount.h, not sys/vfs.h. Gbp-Dch: ignore
2016-08-26Add missing includes and external definitionsJulian Andres Klode
Several modules use std::array without including the array header. Bad modules. Some modules use STDOUT_FILENO and friends, or close() without including unistd.h, where they are defined. One module also uses WIFEXITED() without including sys/wait.h. Finally, environ is not specified to be defined in unistd.h. We are required to define it ourselves according to POSIX, so let's do that.
2016-08-17add --with-source option and Packages/Sources supportDavid Kalnischkies
We support "./foobar.deb" as a way to install a deb file directly. Recently .changes files were added. This highlights a problem as you can't add the changes file without also trying to install all of them. Now, it could also be handy to add entire Packages/Sources files to perhaps get a bunch of packages in without installing them all implicitly. This commit introduces --with-source which allows to add *.deb, *.changes, *.dsc, source-dirs, Packages & Sources files (the later can also be compressed) without also installing them.
2016-08-10Get rid of the old buildsystemJulian Andres Klode
Bye, bye, old friend.
2016-08-10apt-private: Do not include apti18n.h in headersJulian Andres Klode
This causes build failures when turning translations off.
2016-08-06CMake: Add basic CMake build systemJulian Andres Klode
Introduce an initial CMake buildsystem. This build system can build a fully working apt system without translation or documentation. The FindBerkelyDB module is from kdelibs, with some small adjustements to also look in db5 directories. Initial work on this CMake build system started in 2009, and was resumed in August 2016.
2016-08-04apt-private: #ifdef HAVE_STRUCT_STATFS_F_TYPE, not #ifJulian Andres Klode
While autotools defines all macros to 1 explicitly, CMake only defines them without a value. In such a case, #if fails with an error and #ifdef works. In preparation for a possible switch to CMake and to clean up the code (rest uses #ifdef), use #ifdef here
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
2016-07-22create 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.
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.
2016-06-29eipp: let apt make a plan, not make stuff planeDavid Kalnischkies
Julian noticed on IRC that I fall victim to a lovely false friend by calling referring to a 'planer' all the time even through these are machines to e.g. remove splinters from woodwork ("make stuff plane"). The term I meant is written in german in this way (= with a single n) but in english there are two, aka: 'planner'. As that is unreleased code switching all instances without any transitional provisions. Also the reason why its skipped in changelog. Thanks: Julian Andres Klode Gbp-Dch: Ignore
2016-06-27eipp: provide the internal planer as an external oneDavid Kalnischkies
Testing the current implementation can benefit from being able to be feed an EIPP request and produce a fully compliant response. It is also a great test for EIPP in general.
2016-06-27eipp: implement version 0.1 of the protocolDavid Kalnischkies
The very first step in introducing the "external installation planer protocol" (short: EIPP) as part of my GSoC2016 project. The description reads: APT-based tools like apt-get, aptitude, synaptic, … work with the user to figure out how their system should look like after they are done installing/removing packages and their dependencies. The actual installation/removal of packages is done by dpkg with the constrain that dependencies must be fulfilled at any point in time (e.g. to run maintainer scripts). Historically APT has a super micro-management approach to this task which hasn't aged that well over the years mostly ignoring changes in dpkg and growing into an unmaintainable mess hardly anyone can debug and everyone fears to touch – especially as more and more requirements are tacked onto it like handling cycles and triggers, dealing with "important" packages first, package sources on removable media, touch minimal groups to be able to interrupt the process if needed (e.g. unattended-upgrades) which not only sky-rocket complexity but also can be mutually exclusive as you e.g. can't have minimal groups and minimal trigger executions at the same time.
2016-06-23show right binary name in simulation noticeDavid Kalnischkies
Closes: 825216
2016-06-22add insecure (and weak) allow-options for sources.listDavid Kalnischkies
Weak had no dedicated option before and Insecure and Downgrade were both global options, which given the effect they all have on security is rather bad. Setting them for individual repositories only isn't great but at least slightly better and also more consistent with other settings for repositories.
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
2016-06-08edsp: 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.
2016-06-08move '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.
2016-06-02ignore 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.
2016-05-29try 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
2016-05-28look 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.
2016-05-27prevent C++ locale number formatting in text APIsDavid Kalnischkies
Setting the C++ locale via std::locale::global(std::locale("")); which would otherwise default to the default C locale (aka: unaffected by setlocale) effects the formatting of numeric types in IO streams, which for output for humans is perfectly sensible, but breaks our many text interfaces used and parsed by us and others without expecting the numbers to be formatted. Closes: #825396
2016-05-20don't try to get acquire lock in simulation modeDavid Kalnischkies
The code moving in eb1f04dda07c2b69549ad9fd793cca0e91841b3e moved the acquire stuff above the simulation exit, so before getting locks (and creating/chmod directories) we should be checking if we should actually really do it… [ignore as bugfix of an unreleased commit] Git-Dch: Ignore
2016-05-20fail instead of segfault on unreadable config filesDavid Kalnischkies
The report mentions "apt list --upgradable", but there are others which have inconsistent behavior ranging from segfaulting to doing something with the partial (and hence incomplete) data. We had a recent report about sources.list (#818628), this one mentions prefences, the obvious next step is conf files… so the testcase is adapted to check for all three in file and directory versions and run a bunch of commands each time which should all have more or less the same behavior in such a case (aka error out). Closes: 824503
2016-05-16show final solution in --no-download --fix-missing modeDavid Kalnischkies
This commit moves the creation of the fetcher and with it the calculation of the filenames before the code generation the various lists detailing the solution. This means that simulation comes even so slightly closer to a real run as it will require and parse the package indexes for filenames and queuing of URIs, so that a simulation "using" an unavailable download method actually fails now. The real benefit of this change is through that the rather special but nontheless handy --no-download --fix-missing mode now actually shows what the solution is it will apply to the system rather than the solution it would if it could download all not-downloaded packages.
2016-05-16show globalerrors before asking for confirmationDavid Kalnischkies
Errors cause a kind of automatic no already, but warnings and notices are only displayed at the end of the apt execution even through they could effect the choice of saying yes/no to questions: E.g. if a configuration (file) was ignored you wanted to have an effect or if an external solver you used generated warnings suggesting that the solution might be valid, but bogus non-the-less and similar things. Note that this only moves those messages up to the question if the answer is interactive – not if e.g. -y is used or no question is asked at all so this has an effect only on interactive usage of apt(-get), not script who might be parsing apt output.
