The test would not pass before, because EXTRACT_UNQUOTE|EXTRACT_RETAIN_ESCAPE
didn't work (we'd get "KEY3=val with \\quotation\\" as the last string. Now we
are only doing EXTRACT_UNQUOTE, so we get the expected "KEY3=val with \"quotation\"".

It's hard to even say what exactly this combination means. Escaping is
necessary when quoting to have quotes within the string. So the escaping of
quote characters is inherently tied to quoting. When unquoting, it seems
natural to remove escaping which was done for the quoting purposes. But with
both flags we would be expected to re-add this escaping after unqouting? Or
maybe keep the escaping which is not necessary for quoting but otherwise
present? This all seems too complicated, let's just forbid such usage and
always fully unescape when unquoting.
without using -type f, the logs print an error such as:
E: E: modprobe: FATAL: Module asymmetric_keys not found in directory /lib/modules/4.15.0-54-generic
while this doesn't appear to cause problems, it can be extremely
distracting when trying to debug real failures.
Almost all tests were manually mounting/unmounting $TESTDIR/root
from the loopback image; this moves all that into test-functions
so the test setup functions are simplier.
Also add test_setup_cleanup() function, to cleanup what is mounted
by create_empty_image_rootdir()
Commit fb39af4ce4 forgot to restore the default
rlimit values (RLIMIT_NOFILE and RLIMIT_MEMLOCK) while PID1 is reloading.
This patch extracts the code in charge of initializing the default values for
those rlimits in order to create dedicated functions, which take care of their
initialization.
These functions are then called in parse_configuration() so we make sure that
the default values for these rlimits get restored every time PID1 is reloading
its configuration.
Even if addresses provided by DHCP is assigned, the state file may not
be written yet, or resolved may not receive the state change signal
yet, or resolved may not process the signal yet...
Now we first gather all process metadata and populate the process info cache
with them. In this way, the cache only references metadata recorded in iovecs[]
so there's no need to bother freeing (part of) cached metadata later.
The other advantage is that the coredump handler mode and the service mode are
more similar as the cache is populated in the same way for both cases.
It also renames the array indexes so it becomes clear which metadata are passed
by the kernel and which ones are retrieved from the runtime environment.
'input_fd' variable name is used mostly everywhere except in process_socket()
where it's named 'coredump_fd', which is pretty confusing since 'coredump_fd'
is used for the coredump filename in submit_coredump().
So let's use 'input_fd' consistently as name for the pipe fd passed by the
kernel.
No functional changes.
