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.

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.

Hardcoding /var/crash means we can't test it properly and it isn't
really our style.
|
|
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.
|
|
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.

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.

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.

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…
|
|
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).

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.
|
|
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.

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.

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.

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.

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.

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.

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.

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.

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 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).

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.

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).

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).

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.

The fd moves out of scope here anyway, so we should close it properly
instead of leaking it which will tickle down to dpkg maintainer scripts.
