Most pagers are nice and default to running non-interactively if they
aren't connected to a terminal and we relied on that. On ci.debian.net
the configured pager is printing a header out of nowhere though, so if
we are printing to a non-terminal we call "cat" instead.
In the rework we also "remove" the dependency on sensible-utils in sofar
as we call some alternatives if calling the utils fail.
This seems to be the last problem preventing a "PASS" status on
ci.debian.net, so we close the associated bugreport.
rework PTY magic to fix stair-stepping on kfreebsd
A pty slave we have got from openpty can only be used for one dpkg
child, if we give it to a second child on kfreebsd setting TIOCSCTTY
fails causing the output to be stair-stepped from now on.
By switching the code to creating a master and opening a new slave in
the child for each child we can fix this glitch, so that at least the
master remains stable.
APT treats upgrades like installs and dpkg is very similar in this, but
prints still a slightly different processing message indicating that it
is really an upgrade which we hadn't parsed so far, but this wasn't
really visible as we quickly moved on to a 'known' state.
More problematic was the reinstall case as apt hadn't recognized this
for the package name detection, so that reinstalls had no progress since
we introduced MultiArch.
Commit cbcdd3ee9d86379d1b3a44e41ae8b17dc23111d0 removes the space at the
end of the debfile name dpkg send to us and we previously had included
in the pmerror message we printed on the statusfd.
Instead of trying to inspect /proc and the fds inside we use "test -t 1"
instead as this is available and working on kfreebsd as well – not that
something breaks if we wouldn't, but we like color.
Using 'kfreebsd' here makes the test fail on a kfreebsd system
(obviously), so we just use something totally madeup in the hope that
this is less like to conflict in the future.
No reason in and of by itself at the moment, but prepares for the goal
of having 'apt search' and 'apt-cache search' using the same code now
that they at least support the same stuff. The 'apt' code is just a
multitude slower at the moment…
The method already deals with a format string, but had an else path
doing a hardcoded format as well. This is changed now to use the same
code for both - the format in the second case is still fixed though.

Ensure we have a Policy in CacheFile.BuildDepCache()
This partly reverts d059cc2 and fixes bug #753297 in a more
general way by ensuring that CacheFile.BuildDepCache() builds

Fix incorrect upgradable listing in "apt list" (thanks to Michael Musenbrock)
The "apt list" command was using only the pkgDepCache but not the
pkgPolicy to figure out if a package is upgradable. This lead to
incorrect display of upgradable package when the user used the
policy to pin-down packages. Thanks to Michael Musenbrock for the
initial patch.

Use heap to allocate PatternMatch to avoid potential stack overflow
When apt-cache search with many args (> 130) is given the allocation
of PatternMatch on the stack may fail resulting in a segmentation
fault. By using the heap the max size is much bigger and we also
get a bad_alloc expection instead of a segfault (which we can catch
*if* this ever becomes a pratical problem). No test for the crash
as its not reproducable with the MALLOC_ settings in framework.

Make Proxy-Auto-Detect check for each host

initialize iPolicyBrokenCount in DepCache::Update
All other counters are correctly initialized here, expect this one. The
practical effect is low as in apt we usually just do "!= 0" checks, but
only correct counters are good counters.
APT supported versioned provides for a long while in an attempt to get
it working with rpm. While this support is old, we can be relatively
sure that it works as versioned provides are used internally to make
Multi-Arch:foreign work.
Previous versions of apt will print a warning indicating that the
versioned provides is ignored, so that something which "Provides: foo (=
2)" doesn't provide anything.
Note that dpkg does allow only a equals-relation in the provides line
as anything else is deemed too complex. apt doesn't support anything
else either and such a support would require potentially big changes.
add dpkg::source-options for dpkg-source invocation
dpkg-source can be told to enforce signature checks with
--require-valid-signature, but while this isn't feasible as default for
Debian itself at the moment, a local admin should be able to use it.
This commit also fixes the size limit on the construction of the command
being called for dpkg-source and dpkg-buildpackage.
Not all are needed for all files at the moment, but the new docbook
building hadn't available some of the entities it used as the files
weren't correctly copied around in all cases and having the same across
the bord makes working with all of them a little easier.
Our integration tests need some additional dependencies to run and
function correctly, but while multiple places run them, there is no need
to also specify the these dependencies in multiple places.

Fix SmartConfigure to ignore ordering of packages that are already valid
With the change of SmartConfigure() in git commit 42d51f the ordering

time this was not needed. Now it will first check all targets of the
given dependency and only if there is not a good one try to reorder
and unpack/configure as needed.

StringToBool: only act if the entire string is consumed by strtol()
StringToBool uses strtol() internally to check if the argument is
a number. This function stops when it does not find any more numbers.
So a string like "0ad" (which is a valid packagename) is interpreted
as a "0". The code now checks that the entire string is consumed
not just a part of it. Thanks to Johannes Schauer for raising this
issue.
The behaviour of echo "\tA\t" differs between dash/zsh which interprets
the \t as tab and bash which prints it literally. Similar things happen
for other escape sequences – without the -e flag.
Switching to printf makes this more painless^Wportable, so that the
tests are also working correctly with bash as sh.
(commit message by committer, patch otherwise unmodified)
A call to UniqFindTagWrite can trigger the need for a bigger mmap, which
is usually done by moving it, but with this move all pointers into it
become invalid (and have to be remapped). The compiler calculates the
pointer before the execution of the call though, so it tries to store
the returned value at the old location, resulting in a segfault.
We solve this by use of a temprorary variable as we did in the other
instances of this problem before.
The name suggests that it is supposed to substitute a variable with a
value, but we tend to use it in a more liberal replace_all() fashion,
but this breaks if either of the parameters is empty or more importantly
if two "variable" occurrences follow each other directly.
don't send pkg from an unknown architecture via EDSP
APT's cache can include packages from architectures dpkg has no
knowledge about and can therefore not be installed for e.g. to allow
easy lookups. There is no point in telling external solvers about them
though and some of them might even be really talkative about ignoring
them if we do.
