2019-02-26sptr: Remove deprecated smart pointer classesJulian Andres Klode
Please use the standard C++ variants instead.
2019-02-13Introduce APT::Install::Pre-Invoke / Post-Invoke-SuccessJulian Andres Klode
These will run in our frontends currently, and can show messages. For the sake of keeping the implementation complexity low, a non-success variant of Post-Invoke is not provided. LP: #1815761
2019-01-27Add a "reinstall" command as an alias for "install --reinstall".Josh Triplett
aptitude has a similar "reinstall" command for precedent.
2018-12-03Provide a "autopurge" shortcutJulian Andres Klode
This adds a new "autopurge" command that will is a shortcut for "autoremove --purge" Thanks: Michael Vogt for the initial work
2018-08-07Add support for dpkg frontend lockJulian Andres Klode
The dpkg frontend lock is a lock dpkg tries to acquire except if the frontend already acquires it. This fixes a race condition in the install command where the dpkg lock is not held for a short period of time between different dpkg invocations. For this reason we also define an environment variable DPKG_FRONTEND_LOCKED for dpkg invocations so dpkg knows not to try to acquire the frontend lock because it's held by a parent process. We can set DPKG_FRONTEND_LOCKED only if the frontend lock really is held; that is, if our lock count is greater than 0 - otherwise an apt client not using the LockInner family of functions would run dpkg without the frontend lock set, but with DPKG_FRONTEND_LOCKED set. Such a process has a weaker guarantee: Because dpkg would not lock the frontend lock either, the process is prone to the existing races, and, more importantly, so is a new style process. Closes: #869546 [fixups: fix error messages, add public IsLocked() method, and make {Un,}LockInner return an error on !debSystem]
2018-05-11Support local files as arguments in show commandDavid Kalnischkies
Now that --with-source is supported in show we can go a little further and add the "syntactic sugar" of supporting deb-files on the commandline directly to give users an alternative to remembering dpkg -I for deb files & as a bonus apt also works on changes files. Most of the code churn is actually to deal with cases probably not too common in reality like mixing packages and deb-files on the commandline and getting the right order for these multiple records. Closes: 883206
2018-05-11Support release selector for volatile files as wellDavid Kalnischkies
The syntax is a bit awkward, but it is the same as for a package name and introducing another syntax wouldn't really help usability, so with apt install ./foo.deb/experimental you will get the dependencies of foo satisfied by your default release, but if this wouldn't satisfy the version requirements the candidate for this dependency is switched to the version from the experimental release. The same applies for apt build-dep ./foo.dsc/stable-backports which was the initial request.
2018-05-11Extend apt build-dep pkg/release to switch dep as neededDavid Kalnischkies
apt install pkg/release follows versioned dependencies in the candidate switching if the current candidate does not satisfy the dependency, so for uniformity the same should be supported in build-dep.
2018-04-15Introduce experimental new hooks for command-line toolsJulian Andres Klode
This allows third-party package managers like snap or flatpak to hook in and suggest alternatives if packages could not be found, for example. This is still highly experimental and the protocol might change in future versions.
2017-07-27Always warn if --force-yes is validly specified, not just if usedJulian Andres Klode
The code only used to warn when it came into a situation where something actually had to be forced. Warn directly after parsing the command-line instead, that's more accurate.
2017-07-12Reformat and sort all includes with clang-formatJulian Andres Klode
This makes it easier to see which headers includes what. The changes were done by running git grep -l '#\s*include' \ | grep -E '.(cc|h)$' \ | xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/' To modify all include lines by adding a space, and then running ./git-clang-format.sh.
2017-07-12Drop cacheiterators.h includeJulian Andres Klode
Including cacheiterators.h before pkgcache.h fails because pkgcache.h depends on cacheiterators.h.
2017-06-26don't show incorrect 'How odd' errror in no-download modeDavid Kalnischkies
Showing messages related to downloading in a mode which can't download is pretty pointless, so instead of trying harder to make it so that these messages do not trigger just skip them entirely. That the message triggered here is an artifact of the implementation in which the download items are finished, while the code expects them to be still pending – even the in a previous run completely downloaded files. Closes: 863635
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
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!
2016-11-02don'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
2016-07-22support "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.
2016-05-29try 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
2016-05-27prevent 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
2016-05-16show 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.
2016-04-28factor out Pkg/DepIterator prettyprinters into own headerDavid Kalnischkies
The old prettyprinters have only access to the struct they pretty print, which isn't enough usually as we want to know for a package also a bit of state information like which version is the candidate. We therefore need to pull the DepCache into context and hence use a temporary struct which is printed instead of the iterator itself.
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
2016-01-02Add new APT::Keep-Downloaded-Packages optionMichael Vogt
This option controls if downloaded packages should be kept after a successful install or if they should be deleted. The default for "apt-get" is that they are kept (just like before). However the default for "apt" is that they get deleted. Closes: #160743

2015-11-04new quiet level -qq for apt to hide progress outputDavid Kalnischkies
-q is for logging and -qqq (old -qq) basically kills every output expect errors, so there should be a way of declaring a middleground in which the output of e.g. 'update' isn't as verbose, but still shows some things. The test framework was actually making use of by accident as it ignored the quiet level in output setup for apt before. Eventually we should figure out some better quiet levels for all tools…
2015-11-04suggest 'apt autoremove' to get right of unneeded packagesDavid Kalnischkies
The bugreport is more conservative in asking for a conditional, but given that this is a message intended to be read by users to be run by users we should suggest using a command intended to be used by users. And while we are at, add sudo to the message – conditional of course. Closes: 801571
2015-11-04support .deb files in upgrade operations as wellDavid Kalnischkies
The main part is refactoring through to allow hiding the magic needed to support .deb files in deeper layers of libapt so that frontends have less exposure to Debian specific classes like debDebPkgFileIndex.
2015-09-14do not discard new manual-bits while applying EDSP solutionsDavid Kalnischkies
In private-install.cc we call MarkInstall with FromUser=true, which sets the bit accordingly, but while applying the EDSP solution we call mark install on all packages with FromUser=false, so MarkInstall believes this install is an automatic one and sets it to auto – so that a new package which is explicitely installed via an external solver is marked as auto and is hence also up for garbage collection in a following call. Ideally MarkInstall wouldn't reset it, but the detection is hard to do without regressing in other cases – and ideally ideally MarkInstall wouldn't deal with the autobit at all – so we work around this on the calling side for now.
2015-08-27install: Set a local deb as the candidate for that packageJulian Andres Klode
This ensures that we can install .deb files that are not the candidate for a given package.
2015-08-16Replace "extra" in "the following extra packages [...]" by "additional"Julian Andres Klode
This breaks the translation for no big gain, but we broke enough strings already for that to not really matter anymore. Closes: #82430
2015-08-16install: If package already is the newest version, display versionJulian Andres Klode
Also do it unconditionally, as it does not hurt. Closes: #315149
2015-08-14Make auto-remove and auto-clean aliases for the versions without -Julian Andres Klode
Some people type them instead of autoremove and autoclean, so make them happy. Closes: #274159 Makes-Happy: Ansgar
2015-08-14Replace --force-yes by various options starting with --allowJulian Andres Klode
This enables more fine grained control over such exceptions.
2015-08-13Mark SPtr as deprecated, and convert users to std::unique_ptrJulian Andres Klode
Switch to std::unique_ptr, as this is safer than SPtr.
2015-08-10add volatile sources support in libapt-pkgDavid Kalnischkies
Sources are usually defined in sources.list (and co) and are pretty stable, but once in a while a frontend might want to add an additional "source" like a local .deb file to install this package (No support for 'real' sources being added this way as this is a multistep process). We had a hack in place to allow apt-get and apt to pull this of for a short while now, but other frontends are either left in the cold by this and/or the code for it looks dirty with FIXMEs plastering it and has on top of this also some problems (like including these 'volatile' sources in the srcpkgcache.bin file). So the biggest part in this commit is actually the rewrite of the cache generation as it is now potentially a three step process. The biggest problem with adding support now through is that this makes a bunch of previously mostly unusable by externs and therefore hidden classes public, so a bit of further tuneing on this now public API is in order…
2015-08-10remove the compatibility markers for 4.13 abiDavid Kalnischkies
We aren't and we will not be really compatible again with the previous stable abi, so lets drop these markers (which never made it into a released version) for good as they have outlived their intend already. Git-Dch: Ignore
2015-08-10show or-groups in not-installed recommends and suggests listsDavid Kalnischkies
Further abstracting our new ShowList allows to use it for containers of strings as well giving us the option to implement an or-groups display for the recommends and suggests lists which is a nice trick given that it also helps with migrating the last remaining other cases of old ShowList.
2015-08-10implement a more generic ShowList methodDavid Kalnischkies
apt-get is displaying various lists of package names, which until now it was building as a string before passing it to ShowList, which inserted linebreaks at fitting points and showed a title if needed, but it never really understood what it was working with. With the help of C++11 the new generic knows not only what it works with, but generates the list on the fly rather than asking for it and potentially discarding parts of the input (= the non-default verbose display). It also doubles as a test for how usable the CacheSets are with C++11. (Not all callers are adapted yet.) Git-Dch: Ignore
2015-08-10prepare cachesets for -std=c++11David Kalnischkies
The "problem" is mostly in the erase() definitions as they slightly conflict and in pre-c++11 are not uniformly in different containers. By differenciating based on the standard we can provide erase() methods for both standards – and as the method is in a template and inline we don't need to worry about symbols here. The rest is adding wrappings for the new forward_list and unordered_set containers and correcting our iterators to use the same trait as the iterator they are wrapping instead of having all of them be simple forward iterators. This allows the use of specialized algorithms which are picked based on iterator_traits and implementing them all is simple to do as we can declare all methods easily and only if they are called they will generate errors (if the underlying iterator doesn't support these). 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
2014-11-08use a abi version check similar to the gcc checkDavid Kalnischkies
Git-Dch: Ignore
2014-10-15check for available space, excluding root reserved blocksDavid Kalnischkies
We are checking the space requirements for ages, but the check uses the free blocks count, which includes the blocks reserved for usage by root. Now that we use an unprivileged user it has no access to these blocks anymore – and more importantly these blocks are a reserve, they shouldn't be used by apt without special encouragement by the user as it would be bad to have dpkg run out of diskspace and maintainerscripts like man-db skip certain actions if not enough space is available freely.
2014-10-07ensure partial dirs are 0700 and owned by _apt:rootDavid Kalnischkies
Reworks the API involved in creating and setting up the fetcher to be a bit more pleasent to look at and work with as e.g. an empty string for no lock isn't very nice. With the lock we can also stop creating all our partial directories "just in case". This way we can also be a bit more aggressive with the partial directory itself as with a lock, we know we will gone need it.
2014-09-27adapt to the new CacheSetHelper APIDavid Kalnischkies
Git-Dch: Ignore
2014-09-27mark pkg(All|Dist)Upgrade as deprecatedDavid Kalnischkies
The comment above their definition marks them already as such, so this is only a formalisation of the deprecation and fixes the occurances we have in our own code together with removing a magic number. Git-Dch: Ignore
2014-09-27fix progress output for (dist-)upgrade calculationDavid Kalnischkies
Previously, we had a start and a done of the calculation printed by higher-level code, but this got intermixed by progress reporting from an external solver or the output of autoremove code… The higherlevel code is now only responsible for instantiating a progress object of its choosing (if it wants progress after all) and the rest will be handled by the upgrade code. Either it is used to show the progress of the external solver or the internal solver will give some hints about its overall progress. The later isn't really a proper progress as it will jump forward after each substep, but that is at least a bit better than before without any progress indication. Fixes also the 'strange' non-display of this progress line in -q=1, while all others are shown, which is reflected by all testcase changes.
