The source name and source versions are not available for not-installed
packages, so we should not try to print anything as that will end up
being bogus, or produce parsing problems for version related virtual
fields.

Closes: #972580

This is commonly confused as one of the values denoting that root is
required, and most probably intended to mean "binary-targets".

These values are case sensitive, but we do not check whether the
packager has used the wrong case, which will then go unnoticed. So
let's check that and error out to avoid surprises.

This makes possible to select the output format for the --print-set and
--print-unset commands. The current values supported are “shell” which
is the current default, and “make”.

Print both the ar member being decompressed, and its size, so that
truncated archives can more easily be detected after the fact.

Closes: #968442

This makes it possible to process files with newlines within, even though
not all of the dpkg suite is prepared to cope with those.

While varbuf_grow() handles 0 sizes fine, we do a check before calling

This makes spotting unexpected values, or output from sanitizers easier.

Unconditionally disabling the output makes diagnosing problems very
hard. Let's do that only on the default silent mode.

These are inconsequential, but shadow actual memory leaks from being
detected by address sanitizers or similar tools.

Check whether the database files exist and ignore them otherwise. If
some database file has been modified, but the current file being
processed does not exist, created an empty backup so that they are
all in sync with their sequence number.

Closes: #969472

When readlink fails inside a $() the whole script fails. Remove the
«set -e» from the bug-script, as making it fail will cause programs
like reportbug to make it way harder to report bugs, which is
counterproductive.

Closes: #968397

This got deprecated upstream in 2014, but only in 2020 the type started
to emit deprecation warnings.

This is clear from the deb822(5) man page, but we can make this more
clear on the brief format description for each of these file formats.

Specify that the day-of-month accepts an optional leading zero, and
the amount of supported spaces.

Reported-by: Axel Beckert <abe@debian.org>

These have always been separated by a single space, in contrast to other
values in the file, but allowing more spaces now would break backwards
compatibility for something that's just aesthetics. Simply document the
expected format.

The glibc project has deprecated this header for some time and made it
emit warnings, and removed it in 2.32. The Linux kernel has removed the
functionality behind the syscall in 5.5.
