Instead of only trying the first host we get via SRV, we try them all as
we are supposed to and if that isn't working we try to connect to the
host itself as if we hadn't seen any SRV records. This was already the
intend of the old code, but it failed to hide earlier problems for the
next call, which would unconditionally fail then resulting in an all
around failure to connect. With proper stacking we can also keep the
error messages of each call around (and in the order tried) so if the
entire connection fails we can report all the things we have tried while
we discard the entire stack if something works out in the end.

If we don't give a specific error to report up it is likely that all
error currently in the error stack are equally important, so reporting
just one could turn out to be confusing e.g. if name resolution failed
in a SRV record list.

If we have files in partial/ from a previous invocation or similar such
those could be symlinks created by file:// sources. The code is
expecting only real files through and happily changes owner,
modification times and permission on the file the symlink points to
which tend to be files we have no business in touching in this way.
Permissions of symlinks shouldn't be changed, changing owner is usually
pointless to, but just to be sure we pick the easy way out and use
lchown, check for symlinks before chmod/utimes.

The generated dump output is incorrect in sofar as it uses the name as
the key for this compressor, but they don't need to be equal as is the
case if you force some of the inbuilt ones to be disabled as our testing
framework does it at times.
This is hidden from changelog as nobody will actually notice while
describing it in a few words make it sound like an important change…

methods/http.cc:640:13: runtime error: reference binding to null pointer
of type 'struct FileFd'
This reference is never used in the cases it has a nullptr, so the
practical difference is non-existent, but its a bug still.

As the volatile sources are parsed last they were sorted behind the
dpkg/status file and hence are treated as a downgrade, which isn't
really what you want to happen as from a user POV its an upgrade.

If we have a (e.g. locally built) deb file installed and do try to
install it again apt complained about this being a downgrade, but it
wasn't as it is the very same version… it was just confused into not
merging the versions together which looks like a downgrade then.
The same size assumption is usually good, but given that volatile files
are parsed last (even after the status file) the base assumption no
longer holds, but is easy to adept without actually changing anything in
practice.

Traditionally all providers are protected providing something as apt
can't know which of them is actually really providing the functionality
for the user ensuring that we don't propose the removal of used stuff,
but that is of course also keeping stuff around which could be removed.
That can cause the collection of multiple old providers until the
provided package is itself no longer needed (e.g. out-of-tree kernel
modules). We combat this by marking providers only from the newest
source package version so that old providers built by older versions of
the same source package can be garbage collected.

As the previous commit, this shouldn't change behavior at all, but
beside being more explicit and perhaps faster its also considerably
shorter (granted, mostly by if0-block elimination).

Piling everything in a single if statement always made my head wobble,
but it hasn't even a benefit as the most common case of a package which
isn't installed passes all of the old if and lands in the non-existent
else-part of the inner if. So beside a subjective cleanup of what goes
on this implementation should also be a bit faster.
No change in behavior should be present.

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.

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.

If we can't read the old file we can't just move forward as that would
discard potentially discard old data (especially other fields). We let
it fail only after we are done writing the new file so a user has the
chance to look into and merge the new data (which is otherwise
discarded).

If a package file is formatted in a way that that no space

wu-ftpd sends the response without parens, whereas we expect
them.
I did not test the patch, but it should work. I added another
return true if Pos is still npos after the second find to make
sure we don't add npos to the string.

Filesize is a silly hash all by itself, but in combination with others
it can be a strong opponent, so ensuring that it is in the list of
hashes and hence checked by the normal course of action the acquire
process takes is a good thing.

Check for cached hash entries to determine which (if any) hash types
need to be generated for the current file.
In 1.0.9, each hash type was handled by a separate method, each of
which checked the cache. It looks like when these code paths were
unified (in a311fb96b84757ef8628e6a754232614a53b7891) the cache
checks were not incorporated into the new method.

Regression introduced in 8f858d560e3b7b475c623c4e242d1edce246025a.
Commands are probably better of always having output through as the
fall through to the generic proxy settings is likely not intended. As
documenting and implementing this more consistently is kind of a
regression through, it is split off into the next commit.

First seen on hurd, but easily reproducible on all systems by removing
the 'execution' bit from the current working directory and watching some
tests (mostly the no-output expecting tests) fail due to find printing:
"find: Failed to restore initial working directory: …"
Samuel Thibault says in the bugreport:
| To do its work, find first records the $PWD, then goes to
| /etc/apt/trusted.gpg.d/ to find the files, and then goes back to $PWD.
|
| On Linux, getting $PWD from the 700 directory happens to work by luck
| (POSIX says that getcwd can return [EACCES]: Search permission was denied
| for the current directory, or read or search permission was denied for a
| directory above the current directory in the file hierarchy). And going
| back to $PWD fails, and thus find returns 1, but at least it emitted its
| output.
|
| On Hurd, getting $PWD from the 700 directory fails, and find thus aborts
| immediately, without emitting any output, and thus no keyring is found.
|
| So, to summarize, the issue is that since apt-get update runs find as a
| non-root user, running it from a 700 directory breaks find.
Solved as suggested by changing to '/' before running find, with some
paranoia extra care taking to ensure the paths we give to find are really
absolute paths first (they really should, but TMPDIR=. or a similar
Dir::Etc::trustedparts setting could exist somewhere in the wild).
The commit takes also the opportunity to make these lines slightly less
error ignoring and the two find calls using (mostly) the same parameters.
Thanks: Samuel Thibault for 'finding' the culprit!

Setting the C++ locale via std::locale::global(std::locale("")); which
would otherwise default to the default C locale (aka: unaffected by
setlocale) effects the formatting of numeric types in IO streams, which
for output for humans is perfectly sensible, but breaks our many text
interfaces used and parsed by us and others without expecting the
numbers to be formatted.

The report mentions "apt list --upgradable", but there are others which
have inconsistent behavior ranging from segfaulting to doing something
with the partial (and hence incomplete) data. We had a recent report
about sources.list (#818628), this one mentions prefences, the obvious
next step is conf files… so the testcase is adapted to check for all
three in file and directory versions and run a bunch of commands each
time which should all have more or less the same behavior in such a case
(aka error out).

Using Pkg.CandVersion() here is wrong as its implementation will return
a candidate based just on the default policy settings ignoring user
preferences and otherwise set candidates (aka: it sidesteps the
pkgDepCache).
This causes M-A:same libraries to be detected as screwed even through
they aren't, so that they end up being kept back.

Failures can happen and APT regardless will do a partial cache
update anyway. Because APT ensures that the list directory is
in a sane state, it makes sense to also call success hooks if
success was only partial - otherwise it loses sync with APT.
Most importantly, this causes the appstream cache to be empty,
see launchpad bug #1562733.
This is somewhat overly optimistic though: As soon as any repository
has nonexisting optional files, the missing optional files are also
treated as success, which means a single broken repository without an
InRelease file still runs Success hooks, even though it really should
not.

Versions which are only available in dpkg/status aren't installable and
apt doesn't pick them as candidate for this reason – for the same reason
such packages shouldn't be sent to an external solver via EDSP. The
packages are pinned to -1, but if the solver has strict pinning disabled
it could end up picking this version anyhow – which is a request apt can
not satisfy.

Daniel Kahn Gillmor highlights in the bugreport that security isn't
improving by having the user import additional keys – especially as
importing keys securely is hard.
The bugreport was initially about dropping the warning to a notice, but
in given the previously mentioned observation and the fact that we
weren't printing a warning (or a notice) for expired or revoked keys
providing a signature we drop it completely as the code to display a
message if this was the only key is in another path – and is considered
critical.
