2016-08-10Merge branch 'cmake'Julian Andres Klode
2016-08-10CMake: Check for ptsname_r() againJulian Andres Klode
This was dropped in autotools as I found no use of the HAVE_PTSNAME_R macro. Turns out it was typoed as HAVE_PTS_NAME_R. Fix the #ifdef and add checks to CMake for it. Closes: #833674
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.

2016-06-10don't leak dpkg statusfd pipe in debuggingDavid Kalnischkies
Not a big deal to leak fds in debugging mode, but for completeness. Git-Dch: Ignore
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.

2015-11-05do not use read() returned value unconditionallyDavid Kalnischkies
A slightly unlikely bug, but lets fix it while slightly reworking this whole function to be slightly saner to look at, even if still not good. Git-Dch: Ignore
2015-11-04wrap every unlink call to check for != /dev/nullDavid Kalnischkies
Unlinking /dev/null is bad, we shouldn't do that. Also, we should print at least a warning if we tried to unlink a file but didn't manage to pull it of (ignoring the case were the file is /dev/null or doesn't exist in the first place). This got triggered by a relatively unlikely to cause problem in pkgAcquire::Worker::PrepareFiles which would while temporary uncompressed files (which are set to keep compressed) figure out that to files are the same and prepare for sharing by deleting them. Bad move. That also shows why not printing a warning is a bad idea as this hide the error for in non-root test runs. Git-Dch: Ignore
2015-11-04sanify API to get 'the' candidate versionDavid Kalnischkies
This was discussed a while ago on #debian-apt and now that I see myself making this mistake lets bite the bullet and fix it in the easy way out version: Using a new name which fits with a similar named setter and deprecate the old method instead of 'hostily' changing API. Closes: #803471
2015-11-04implement a public pkgSystem::MultiArchSupportedDavid Kalnischkies
Some codepaths need to check if the system (in our case usually dpkg) supports MultiArch or not. We had copy-pasted the check so far into these paths, but having it as a system check is better for reusability.

2015-09-14avoid using global PendingError to avoid failing too often too soonDavid Kalnischkies
Our error reporting is historically grown into some kind of mess. A while ago I implemented stacking for the global error which is used in this commit now to wrap calls to functions which do not report (all) errors via return, so that only failures in those calls cause a failure to propergate down the chain rather than failing if anything (potentially totally unrelated) has failed at some point in the past. This way we can avoid stopping the entire acquire process just because a single source produced an error for example. It also means that after the acquire process the cache is generated – even if the acquire process had failures – as we still have the old good data around we can and should generate a cache for (again). There are probably more instances of this hiding, but all these looked like the easiest to work with and fix with reasonable (aka net-positive) effects.

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
2015-08-10fix memory leaks reported by -fsanitizeDavid Kalnischkies

2015-08-10make all d-pointer * const pointersDavid Kalnischkies
Doing this disables the implicit copy assignment operator (among others) which would cause hovac if used on the classes as it would just copy the pointer, not the data the d-pointer points to. For most of the classes we don't need a copy assignment operator anyway and in many classes it was broken before as many contain a pointer of some sort. Only for our Cacheset Container interfaces we define an explicit copy assignment operator which could later be implemented to copy the data from one d-pointer to the other if we need it. Git-Dch: Ignore
2015-06-12store Release files data in the CacheDavid Kalnischkies
We used to read the Release file for each Packages file and store the data in the PackageFile struct even through potentially many Packages (and Translation-*) files could use the same data. The point of the exercise isn't the duplicated data through. Having the Release files as first-class citizens in the Cache allows us to properly track their state as well as allows us to use the information also for files which aren't in the cache, but where we know to which Release file they belong (Sources are an example for this). This modifies the pkgCache structs, especially the PackagesFile struct which depending on how libapt users access the data in these structs can mean huge breakage or no visible change. As a single data point: aptitude seems to be fine with this. Even if there is breakage it is trivial to fix in a backportable way while avoiding breakage for everyone would be a huge pain for us. Note that not all PackageFile structs have a corresponding ReleaseFile. In particular the dpkg/status file as well as *.deb files have not. As these have only a Archive property need, the Component property takes over this duty and the ReleaseFile remains zero. This is also the reason why it isn't needed nor particularily recommended to change from PackagesFile to ReleaseFile blindly. Sticking with the earlier is usually the better option.

2015-04-07fix crash in order writing in pkgDPkgPM::WriteApportReport()Michael Vogt
libapt can be configured to write various bits of information to a file creating a report via apport. This is disabled by default in Debian and apport residing only in /experimental so far, but Ubuntu and other derivatives have this (in some versions) enabled by default and there is no regression potentially here. The crash is caused by a mismatch of operations vs. strings for operations, so adding the missing strings for these operations solves the problem. [commit message by David Kalnischkies] LP: #1436626

2014-12-23pass-through stdin fd instead of content if not a terminalDavid Kalnischkies
Commit 299aea924ccef428219ed6f1a026c122678429e6 fixes the problem of not logging terminal in case stdin & stdout are not a terminal. The problem is that we are then trying to pass-through stdin content by reading from the apt-process stdin and writing it to the stdin of the child (dpkg), which works great for users who can control themselves, but pipes and co are a bit less forgiving causing us to pass everything to the first child process, which if the sending part of the pipe is e.g. 'yes' we will never see the end of it (as the pipe is full at some point and further writing blocks). There is a simple solution for that of course: If stdin isn't a terminal, we us the apt-process stdin as stdin for the child directly (We don't do this if it is a terminal to be able to save the typed input in the log). Closes: 773061
2014-12-23always run 'dpkg --configure -a' at the end of our dpkg callingsDavid Kalnischkies
dpkg checks now for dependencies before running triggers, so that packages can now end up in trigger states (especially those we are not touching at all with our calls) after apt is done running. The solution to this is trivial: Just tell dpkg to configure everything after we have (supposely) configured everything already. In the worst case this means dpkg will have to run a bunch of triggers, usually it will just do nothing though. The code to make this happen was already available, so we just flip a config option here to cause it to be run. This way we can keep pretending that triggers are an implementation detail of dpkg. --triggers-only would supposely work as well, but --configure is more robust in regards to future changes to dpkg and something we will hopefully make use of in future versions anyway (as it was planed at the time this and related options were implemented). Note that dpkg currently has a workaround implemented to allow upgrades to jessie to be clean, so that the test works before and after. Also note that test (compared to the one in the bug) drops the await test as its is considered a loop by dpkg now. Closes: 769609
2014-12-23do not make PTY slave the controlling terminalDavid Kalnischkies
If we have no controlling terminal opening a terminal will make this terminal our controller, which is a serious problem if this happens to be the pseudo terminal we created to run dpkg in as we will close this terminal at the end hanging ourself up in the process… The offending open is the one we do to have at least one slave fd open all the time, but for good measure, we apply the flag also to the slave fd opening in the child process as we set the controlling terminal explicitely here. This is a regression from 150bdc9ca5d656f9fba94d37c5f4f183b02bd746 with the slight twist that this usecase was silently broken before in that it wasn't logging the output in term.log (as a pseudo terminal wasn't created). Closes: 772641

2014-12-07correct architecture detection for 'rc' packages for purgeDavid Kalnischkies
We were already considering these cases, but the code was flawed, so that packages changing architectures are incorrectly handled and hence the wrong architecture is used to call dpkg with, so that dpkg says the package isn't installed (which it isn't for the requested architecture). Closes: 770898
2014-11-28fix PTY interaction on linux and kfreebsdDavid Kalnischkies
We run dpkg on its own pty, so we can log its output and have our own output around it (like the progress bar), while also allowing debconf and configfile prompts to happen. In commit 223ae57d468fdcac451209a095047a07a5698212 we changed to constantly reopening the slave for kfreebsd. This has the sideeffect though that in some cases slave and master will lose their connection on linux, so that no output is passed along anymore. We fix this by having always an fd referencing the slave open (linux), but we don't use it (kfreebsd). Failing to get our PTY up and running has many (bad) consequences including (not limited to, nor all at ones or in any case) garbled ouput, no output, no logging, a (partial) mixture of the previous items, … This commit is therefore also reshuffling quiet a bit of the creation code to get especially the output part up and running on linux and the logging for kfreebsd. Note that the testcase tries to cover some cases, but this is an interactivity issue so only interactive usage can really be a good test. Closes: 765687
