Let's move things closer to journald's configuration settings, which
knows Compress= already, as a boolean. This makes things more uniform,
but also gives us more freedom to possibly swap out the used compression
algorithm one day.
This sounds overly low-level and implementation-detaily. Let's just
use the default level XZ suggests. This gives us more room to possibly
swap out the compression algorithm used, as the compression level range
will not leak into user configuration.
When disk space taken up by coredumps grows beyond a configured limit
start removing the oldest coredump of the user with the most coredumps,
until we get below the limit again.
Add a Rapid Commit option to Solicit messages and expect a Reply to
be received instead of an Advertise. When receiving a DHCPv6 message
from the server in state Solicit, continue testing whether the
message is a Reply. Ease up the message type checking, it's not fatal
if the message is of a wrong type.
Add helper functions to set/get the rapid commit of a lease. See
RFC 3315, sections 17., 17.1.2., 17.1.4. and 18.1.8.
Start sending Renew and Rebind DHCPv6 messages when respective timers T1
and T2 expire. Rebind messages do not include a Server ID option and the
Rebind procedure ends when the last IPv6 address valid lifetime expires,
whereafter the client restarts the address acquisition procedure by
Soliciting for available servers.
See RFC 3315, sections 18.1.3. and 18.1.4. for details.
Create a helper function to compute the remaining time in seconds from
time T2 to the IPv6 address with the longest lifetime. The computed
time is used as the Maximum Retransmission Duration in Rebinding state.
See RFC 3315, section 18.1.4. for details.
Provide a function to request more options from the DHCPv6 server.
Provide a sensible default set at startup and add test basic test
cases for the intended usage.
Define DNS and NTP related option codes and add comments for the
unassigned codes.
Patch fixes some incorrect-looking code in transaction.c.
It could fix cases where Debian users with bad package configurations
had systemd go into an infinite loop printing messages about breaking an
ordering cycle, though I have not reproduced that problem myself.
transaction_verify_order_one() considers jobs/units outside current
transaction when checking whether ordering dependencies cause cycles.
It would also incorrectly try to break cycles at these jobs; this
cannot work, as the break action is to remove the job from the
transaction, which is a no-op if the job isn't part of the transaction
to begin with. The unit_matters_to_anchor() test also looks like it
would not work correctly for non-transaction jobs. Add a check to
verify that the unit is part of the transaction before considering a
job a candidate for deletion.

So that building from an archive works even if intltool is not present.
The README file already mentioned that intltool should only be required
when building from git.
Tested: Built it from the distribution archive on a host without intltool.
$ ./configure --enable-polkit
$ make
IT_PROG_INTLTOOL makes configure fail if intltool is not present. If we can
not find intltool, then disable NLS (otherwise make in po/ fails since MSGFMT
will not be defined.)
Tested: Built it on a host without intltool.
$ ./configure --enable-nls
...
checking for intltool-merge... no
configure: error: --enable-nls requested but intltool not found
$ ./configure --disable-polkit
...
checking for intltool-merge... no
configure: WARNING: *** Disabling NLS support because intltool was not found
checking whether NLS is requested... no
...
$ make
https://bugs.freedesktop.org/show_bug.cgi?id=79692
In particular, disable intltool when --disable-nls is passed to configure.
Tested: Built it on a host without intltool or gettext.
$ ./configure --disable-nls --disable-polkit
$ make
Add Compression={none,xz} and CompressionLevel=0-9 settings. Defaults
are xz/6.
Compression=filesystem may be added later.
I picked "xz" for the compression "type", since we might want to add
different compressors later on. XZ is fairly memory and CPU intensive, and
embedded users will likely want to use LZO or some other lightweight compression
mechanism.
Unfortunately the core is first written uncompressed, then compressed
by reading from disk and writing to the output file. This is ugly and
slow, but I don't see a way around, if we want to get the backtrace
without keeping everything in memory.
When running in 'quiet' mode, the only message printed from shutdown
binary would be 'Cannot finalize remaining file systems and devices,
giving up.', the only log line at error level before switch back to
initramfs. This is misleading, because in initramfs everything will
be cleaned up properly.
Avoid printing anything at error level before the attempt to switch
back to initramfs. Rework the messages to contain a bit more
information what is still remaining, to help people diagnose shutdown
issues.
