2018-09-28Add 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] (cherry picked from commit c2c8b4787b0882234ba2772ec7513afbf97b563a) LP: #1781169 (cherry picked from commit 6c0c94ed32b8e679b14b0f89b51c1c336dc0ab9c)
2017-02-22use 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 (cherry picked from commit c15ba854b6736696f164e4d2c243a944e2d4006e) (cherry picked from commit c0dc26456ba74da449eae11c04c3edb3b5f1e35e)
2017-02-22don'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.

2016-08-31factor 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

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).

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.

2014-09-27mark 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.

2014-05-30if Resolver fails, do not continue even if not brokenDavid Kalnischkies
This can happen if the request is already a well-formed request all by itself (e.g. the package has no dependencies), but the resolver found a reason to not accept it as solution. Our edsp 'dump' solver e.g. shouldn't be able to trigger install, which it does otherwise.

2013-10-03put fetch errors in 'source' on our errorstackDavid Kalnischkies
refactor the fetching process so that it looks more like the others we have in the hope that we can reuse code in the future. This is a soft interface change as 'source' previously printed errors directly on stderr, while it will now push it onto our usual error stack.
2013-09-26print-uris prints regardless of quiet-level againDavid Kalnischkies
While the InstallPackages code was moved from apt-get into the private library the output was moved from (std::)cout to c1out which isn't shown in quiet level 2 (and above), so we flip back to std::cout to ensure that it is always printed as you are not going to use --print-uris if you don't want to see the uris… Closes: 722207
