2016-12-31fix minimum pkgs option for dpkg --recursive usageDavid Kalnischkies
Interpreting a boolean as an int works just fine – it just hasn't the intended result – it isn't a serious problem through as the disabling of the usage of this dpkg calling style is just an "optimization"

2016-11-24skip unconfigure for unconfigured to-be removed pkgsDavid Kalnischkies
2016-11-24do not configure unconfigured to be removed packagesDavid Kalnischkies
We try to configure all packages at the end which need to be configured, but that also applies to packages which weren't completely installed (e.g. maintainerscript failed) we end up removing in this interaction instead. APT doesn't perform this explicit configure in the end as it is using "dpkg --configure --pending", but it does confuse the progress report and potentially also hook scripts.

2016-11-24don't perform implicit crossgrades involving M-A:sameDavid Kalnischkies
dpkg stumbles over these (#844300) and we haven't dropped 'easier' removes to be implicit and to be scheduled by dpkg by default so far so we shouldn't push the decision in such cases to dpkg either.
2016-11-24improve arch-unqualified dpkg-progress parsingDavid Kalnischkies
Our old idea was to look for the first package which would be "touched" and take this as the package dpkg is talking about, but that is incorrect in complicated situations like a package upgraded to/from multiple M-A:same siblings installed. As we us the progress report to decide what is still needed we have to be reasonabily right about the package dpkg is talking about, so we jump to quite a few loops to get it.
2016-11-23correct cross & disappear progress detectionDavid Kalnischkies
Given that we use the progress information to skip over actions dpkg has already done like not purging a package which was already removed and had no config files or not acting on disappeared packages and such it is important that apt and dpkg agree on which states the package has to pass through. To ensure that we keep tabs on this in the future a warning is added at the end if apt hasn't seen all the action it was supposed to see. I can't wait for the first bugreporters to wonder about this…
2016-11-23react to trig-pend only if we have nothing else to doDavid Kalnischkies
If a package is triggered dpkg frequently issues two messages about it causing us to make a note about it both times which messes up our planned dpkg actions view. Adding these actions if we have nothing else planned fixes this and should still be correct as those planned actions will deal with the triggering just fine and we avoid strange problems like a package triggered before its removed…

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.
2016-08-25treat .ddeb files like .deb, especially for dpkgDavid Kalnischkies
Ubuntu uses *.ddeb files for their debug packages, but the interface we are using since f495992428a396e0f98886c9a761a804aa161c68 to talk to dpkg isn't supporting *.ddeb files. This used to work previously as apt itself isn't caring about the filenames at all and if they are explicitly mentioned dpkg will accept all, too. It might or might not be a good idea to patch dpkg, too, but regardless of it happening, we don't want to couple us to closely to dpkg for this minor feature but testing for this at runtime as it would delay shipping the fix for the too long commandlines further. It is also questionable if it is really a good idea to allow any file extension to be used here (like .foobar in the testcase), but we used to and we tend to avoid breaking existing usecases if we can help it. As a bonus, this also allows the installation of ddeb files directly from the commandline as you can with deb files already. We continue to ignore udeb through as the user-mistake to useful ratio is too high. LP: #1616909
2016-08-24do not restore selections for already purged packagesDavid Kalnischkies
In most cases apt was already skipping the (re)setting of packages as to be removed/purged if dpkg had told us that it already did, but we haven't dealt with it in the most obvious of the cases: Selections set for packages we touched in this operation which either restores selections even dpkg would have overridden or e.g. tries to restore a purge selection for a package which was just purged – does not happen with apt itself as it isn't using selections in this way, but higher frontends like aptitude do. The result in the later case is a warning printed by dpkg that we try to set selections for an unknown package, which is harmless per se, but can be confusing for users and we really shouldn't cause warnings in dpkg if we can help it.

2016-08-23do dpkg --configure before --remove/--purge --pendingDavid Kalnischkies
Commit 7ec343309b7bc6001b465c870609b3c570026149 got us most of the way, but the last mile was botched by having the pending calls in the wrong order as this way we potentially 'force' dpkg to remove/purge a package it doesn't want to as another package still depends on it and the replacement isn't fully installed yet. So what we do now is a configure before remove and purge (all with --no-triggers) and finishing off with another configure pending call to take care of the triggers. Note that in the bugreport example our current planner is forcing dpkg to remove the package earlier via --force-depends which we could do for the pending calls as well and could be used as a workaround, but we want to do less forcing eventually. Closes: 835094
2016-08-19Ignore SIGINT and SIGQUIT for Pre-Install hooksJulian Andres Klode
Instead of erroring out when receiving a SIGINT, let the child deal with it - we'll error out anyway if the child exits with an error or due to the signal. Also ignore SIGQUIT, as system() ignores it. This basically fixes Bug #832593, but: we are running the hooks via sh -c. Some shells exit with a signal error even if the command they are executing catches the signal and exits successfully. So far, this has been noticed on dash, which unfortunately, is our default shell. Example: $ cat trap.sh trap 'echo int' INT; sleep 10; exit 0 $ if dash -c ./trap.sh; then echo OK: $?; else echo FAIL: $?; fi ^Cint FAIL: 130 $ if mksh -c ./trap.sh; then echo OK: $?; else echo FAIL: $?; fi ^Cint OK: 0 $ if bash -c ./trap.sh; then echo OK: $?; else echo FAIL: $?; fi ^Cint OK: 0
2016-08-10disable explicit configuration of all packages at the endDavid Kalnischkies
With b4450f1dd6bca537e60406b2383ab154a3e1485f we dropped what we calculated here later on and now that we don't need it in the meantime either we can just skip the busy work by default and expect dpkg to do the right thing dropping also our little "last explicit configures" removal trick introduced in b4450f1dd6bca537e60406b2383ab154a3e1485f. This enables the last of a bunch of previously experimental options, some of them existing still, but are very special and hence not really worth documenting anymore (especially as it would need to be rewritten now entirely) which is why the documentation is nearly completely dropped. The order of configuration stanzas in the simulation code changes slightly as it isn't concerning itself with finding the 'right' order, but any order is valid anyhow as long as the entire set happens in the same call.
2016-08-10simulate all package manager actions explicitlyDavid Kalnischkies
If a planner lets actions to be figured out by dpkg in pending calls these actions aren't mentioned in a simulation. While that might be a good thing for debugging, it would be a change in behavior and especially if a planner avoids explicit removals could be confusing for users. As such we perform the same 'trick' as in the dpkg implementation by performing explicitly what would be done by the pending calls. To save us some work and avoid desyncs we perform a layer violation by using deb/ code in the generic simulation – and further we perform ugly dynamic_cast to avoid breaking the ABI for nothing; aptitude is the only other user of the simulation class according to codesearch.d.n and for that our little trick works. It just isn't working if you happen to extend pkgSimulate or otherwise manage to call the protected Go methods directly – which isn't very realistic/practical.
2016-08-10try to avoid removal of crossgraded packagesDavid Kalnischkies
The user has to approve the removal of a crossgraded package as it might be needed to remove it (temporarily) in the process, but in most cases we can happily avoid it and let dpkg unpack over it skipping the remove. This has some effects on progress reporting and how deal with selections through which makes this a tiny bit complicated.
2016-08-10ensure all removes are reported to hook scriptsDavid Kalnischkies
Same reason and implementation as for configure.
2016-08-10ensure all configures are reported to hook scriptsDavid Kalnischkies
A planner might not explicitly configure all packages, but we need to know all packages which will be configured for progress reporting and to tell the hook scripts about them as they rely on this for their own functionality.
2016-08-10don't purge directly, but remove and do purge at the endDavid Kalnischkies
If we want a package to be purged from the system tell dpkg in the ordering (if it has to touch it explicitly) to remove it and cover the purging of the config files at the end with a --purge --pending call. That should help packages move conffiles around between packages correctly even if the user is purging packages directly in big actions like dist-upgrades involving many packages.
2016-08-10call dpkg with --no-triggers by defaultDavid Kalnischkies
Implemented a long while ago now with relatively good progress reporting involving triggers is a good time to try delaying the execution of triggers across dpkg invocations finally by default. Note: The bugreport talks also about 'smarter' configuration which is a much bigger part and approached from multiple directions, but doesn't really involve triggers per-se so considering it decoupled should help in getting it done… Closes: #626599
2016-08-10select remove/purge packages early on for dpkgDavid Kalnischkies
Telling dpkg early on that we are going to remove these packages later helps it with auto-deconfiguration decisions and its another area where a planner can ignore the nitty gritty details and let dpkg decide the course of action if there are no special requirements.
2016-08-10save and restore selection states before/after calling dpkgDavid Kalnischkies
dpkg decides certain things on its own based on selections and especially if we want to call --pending on purge/remove actions, we need to ensure a clean slate or otherwise we surprise the user by removing packages we weren't allowed to remove by the user in this run (the selection might be an overarching plan for the not-yet "future"). Ideally dpkg would have some kind of temporal selection interface for this case, but it hasn't, so we make it temporal with the risk of loosing state if we don't manage to restore them.
2016-08-10use dpkg --unpack --recursive to avoid long cmdlinesDavid Kalnischkies
Having long commandlines split into two is a huge problem if it happens and additionally if we want to introduce planners which perform less micromanagment its a good idea to leave the details for dpkg to decide. In practice this doesn't work yet unconditionally as a bug is hiding in the ordering code of dpkg, but it works if apt imposes its ordering so this commit allows for now at least to solve the first problem.
2016-08-10pass --force-remove-essential to dpkg only if neededDavid Kalnischkies
APT (usually) knows which package is essential or not, so we can avoid passing this force flag to dpkg unconditionally if the user hasn't chosen a non-default essential handling obscuring the information.

2016-08-10CMake: Check for ptsname_r() againJulian Andres Klode

2016-08-07Handle interrupt when running Pre-Install hooksJulian Andres Klode
If we receive an interrupt, set a flag and do not abort immediately without waiting for the child. Once the child exited, exit with an error if the interrupted flag is set. Closes: #832593
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.
2016-06-29write auto-bits before calling dpkg & again after if neededDavid Kalnischkies
Writing first means that even in the event of a power-failure the autobit is saved for future processing instead of "forgotten" so that the package is treated as manually installed. In some cases we have to re-run the writing after dpkg is done through as dpkg can let packages disappear and in such cases apt will move autobits around (or in that case non-autobits) which we need to store.
2016-06-29Revert "travis: use gcc-5 instead of gcc(-4.8)"David Kalnischkies
This reverts commit 2b8221d66a8284042fc53c7bbb14bb9750e9137f. Avoiding the use of GCC >= 5 stuff lets use go back to 4.8 simplifying the travis setup again as well as reducing the backport requirements in general. This is possible because the std::get_time use requiring GCC >= 5 in 9febc2b238e1e322dce1f94ecbed46d595893b52 was replaced by handrolling it in 1d742e01470bba27715a8191c50adde4b39c2f19, so the remaining uses are just small conviniences we can do without.

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).

2016-05-03let DPKG_COLORS default to our APT::Color settingDavid Kalnischkies
dpkg can optionally colorize its output since 1.18.5. Currently this defaults to 'never', but it will eventually be 'auto'. It seems reasonable to assume that a user who has enabled/disabled colors in apt will want to have dpkg have the same state regarding color usage. This isn't overriding explicit settings by the user, so in case a user feels strongly about it one way or the other there are options.
2016-03-14streamline dpkgpm cleanup-handlingDavid Kalnischkies
The (unlikely) waitpid failure case should fallthrough the code just like the other failures (and successes) instead of taking a shortcut avoiding all the cleanup (progress) and finishing touches (log, state). This also delays the cleanup of the progress until apt is really done with everything and "just" has the post-invokes left to do, so the period of 'apt looks finished as it stopped the progress' and 'apt really finished as I have the shell-prompt back' is shorter even if there is no progress reported anymore, so the bar lingers at 100%… Ideally even the post-invokes would be covered by progress, but they can have their own output and dealing with that could be hard. Git-Dch: Ignore
