If a external command closes the PIPE unexpectedly, do not crash
in pkgDPkgPM::RunScriptsWithPkgs but ignore the SIGPIPE.

|
This debug option will display all scripts that are run
by apts RunScripts and RunScriptsWithPkgs helpers.

In commit 446551c8 I changed MarkInstall to discard the candidate if the
candidate can't satisfy the dependency. This breaks interactive solvers
like aptitude which can change the candidate on-the-fly later.
In commit df77d8a5 I introduced this 'early' loop-breaking to begin with
which can't be that helpful for interactive solvers as well, but makes
perfect sense for non-interactives to stop them from exploring trees
which can't be satisfied, but it isn't perfect as ideally we would check
this before auto-installing the first dependency.
This commit therefore moves the loop into its own IsInstallOk hook so
that frontends can override this check if they want to and in exchange
removes the loop-breaking from MarkInstall itself and does it before any
dependency is installed.

Hooked checks could be influenced by AutoInst as a lot can happen
between a call without and one with this bit set. The real cache-hit
check is above this call already. Individual hooked checks can then
inspect the state if they want to cache. Calling them multiple times
shouldn't be a problem either way.

We have to properly close our pseudo terminals even in error cases
before we call post-invoke scripts. This is done now by breaking from
the dpkg calling loop instead of copying the handling, which did it in
the wrong order before.
This also ensures that our state file is written in error cases to
record autobit and co as this was forgotten before.

This methods should not be used by anyone expect the library itself as
they are helpers for the specific class and therefore perfect candidates
for hidding.

While it is a huge undertaking to enable it for our public libraries as
basically everything we exported so far could be seen as public
interface our private library is new and under our full control, so we
can do whatever we like with it. The benefits are not that big in return
of course, but it reduces the size a bit, so thats great nontheless.

It can happen that content in our buffer is not enough to produce a
meaningful output in which case no output is created by liblzma, but
still reports that everything is okay and we should go on.
The code assumes it has reached the end through if it encounters a null
read, so this commit makes it so that it looks like this read was
interrupted just like the lowlevel read() on uncompressed files could.
It subsequently fixes the issue with that as well as until now our loop
would still break even if we wanted it to continue on.
(This bug triggers our usual "Hash sum mismatch" error)

AutoClose is both an argument in OpenDescriptor() and an enum. In
commit 84baaae93badc2da7c1f4f356456762895cef278 code using the AutoClose
parameter was moved to OpenDescriptorInternal(). In that function,
AutoClose meant the enum value, so the check was always false.

Otherwise the "WARNING: The following packages cannot be authenticated!"

We have xz/lzma support for a while, but only via an external binary
provided by xz-utils. Now that the Debian archive provides xz by default
and dpkg pre-depends on the library provided by liblzma-dev we can switch
now to use this library as well to avoid requiring an external binary.
For now the binary is in a prio:required package, but this might change
in the future.
API wise it is quiet similar to bz2 code expect that it doesn't provide
file I/O methods, so we piece this together on our own.

In #737085 we see that apt can be confused if informations about
versions only differ slightly. This commit adds a way of at least adding
a few more data points with the next abi break to help a bit with it.

Old code limited lines to 250 characters which is probably enough for
everybody, but who knows… It also takes care of device nodes which start

Commit 62dcbf84 changed the code of ident to look more like the code for
add on my suggestion. This made ident interactive as it starts with a
unmount, press enter, mount cycle. The first two are skipped now.
This fixes d-i/apt-setup which is using it to get ID as well as label.

The mountpoint might be auto-generated by the mount command so pushing
an error on the stack will confuse the following code and let it believe
an unrecoverable error occured while potentially everything is okay.
Same goes for umount as a non-existing mountpoint is by definition not
mounted.
|
|
Checking that parent-directory of mountpoint and mountpoint are on
different devices is fine most of the time, but is too restrictive
for our testcases and there shouldn't be anything wrong with 'normal'
users copying disk-contents around either if they want to.
We check for the existance of the ".disk/" directory now as this will
not be present if the disk isn't 'mounted'. Disks doesn't need to have
such a directory through, so for those we fall back to the old way of
detecting mounted or not mounted.

The unpack of a M-A:same package will force the unpack of all its
siblings directly to prevent that they could be separated by later
immediate actions. In commit 634985f8 a call to SmartConfigure was
introduced to configure these packages at the time the installation
order encounters them. Usually, the unpack order is already okay, so
that this 'earlier' unpack was not needed and if it wouldn't have been
done, the package would now only be unpacked, but by configuring the package
now we impose new requirements which must be satisfied. The code is
clever enough to handle this most of the time (it worked for 2 years!),
but it isn't needed and in very coupled cases this can fail.
Removing this call again removes this extra burden and so simplifies the
ordering as can be seen in the modified tests. Famous last words, but I
don't see a reason for this extra burden to exist hence the remove.

Inspired by the rest of the patch in 661537, but abstract the
parsing of various ways of setting the build profiles more so it can
potentially be reused and all apt parts have the same behaviour.
Especially config options, cmdline options and environment will not be
combined as proposed as this isn't APTs usual behaviour and dpkg doesn't
do it either, so one overrides the other as it normally does.

Build-dependencies are now able to include a <profile.foo …>

Automatically handle the override of list options via its parent value
which can even be a comma-separated list of values. It also adds an easy

Prevents that "old" dependencies have an influence in the scoring.
With positive dependencies this is usually not a problem, but negative
dependencies can linger around for a long time.

versioned -dev packages like db and boost have the problem of no
dependencies which would give them a competitive advantage against an
older incarnation of the -dev package, so they tend to be kept back
until the old version is removed from the archive, which, if the user
has older releases in its sources can take a long time (or never happens).
The newer version has a conflicts/breaks against the older one, but the
older one hasn't against the newer, so by giving via the conflicts the
older one a reduced score the newer one can win if there is no other
reason to keep it. If both have a conflict against each other the
scoring will cancel itself out, so no harm done.
This gives "action" a slightly bigger edge in breaks/conflicts cases
than before, but holding back isn't a really good solution anyway.

The current PackageContainerInterface::FromString() will do a
FromFnmatch() first and then FromRegEx(). This commit reverts
that change to restore the old behavior to only look for RegEx
and not glob-style pattern. The rational is that:
a) currently a fnmatch() is misleadingly reported as a regex match to
the user (Bug#738880)
b) a fnmatch may match something different than a a RegEx so the
change broke a published interface

Commit 6008b79adf1d7ea5607fab87a355d664c8725026 should have been guarded
by "Git-Dch: Ignore", but it wasn't and I only noticed it with the Close
message via deity thinking "hehe, I wonder if someone is gonna notice".
Looks like someone did: hats off to reddit user itisOmegakai!
Good to know that what I do isn't only monitored by goverments. :)
As there is another instance of basically the same code we just factor
out the code a bit and reuse, so its even cleaner and not only simpler.
