As many laptops don't save/restore screen brightness across reboots,
let's do this in systemd with a minimal tool, that restores the
brightness as early as possible, and saves it as late as possible. This
will cover consoles and graphical logins, but graphical desktops should
do their own per-user stuff probably.
This only touches firmware brightness controls for now.
This adds a simple generator that is capable of automatically
discovering certain GPT partitions by their type UUID and mount/enable
them. This currently covers swap partitions and /home partitions, but is
expected to grow more features soon.
This currently doesn't handle LUKS encrypted /home.
This enables all swap partitions of type
0657fd6da4ab43c484e50933c84b4f4f, if found.
This mounts the first partition of type 933ac7e12eb44f13b8440e14e2aef915
as /home, if it is found.
Enable coverage with --enable-coverage.
"make coverage" will create the report locally,
"make coverage-sync" will upload the report to
http://www.freedesktop.org/software/systemd/coverage/.
Requires lcov version 1.10 to handle naming in systemd and to
use the --no-external option.
[zj: make the coverage at least generate something with
separate build dir, simplify rules a bit: all errors
are mine. ]
Embedded folks don't need the machine registration stuff, hence it's
nice to make this optional. Also, I'd expect that machinectl will grow
additional commands quickly, for example to join existing containers and
suchlike, hence it's better keeping that separate from loginctl.
Transient units can be created via the bus API. They are configured via
the method call parameters rather than on-disk files. They are subject
to normal GC. Transient units currently may only be created for
services (however, we will extend this), and currently only ExecStart=
and the cgroup parameters can be configured (also to be extended).
Transient units require a unique name, that previously had no
configuration file on disk.
A tool systemd-run is added that makes use of this functionality to run
arbitrary command lines as transient services:
$ systemd-run /bin/ping www.heise.de
Will cause systemd to create a new transient service and run ping in it.
Implement this with a proper state machine, so that newlines and
escaped chars can appear in string assignments. This should bring the
parser much closer to shell.
This makes it easier to add substitutions to man pages,
avoiding the separate transformation step.
mkdir -p's are removed from the rule, because xsltproc will
will create directories on it's own.
All in all, two or three forks per man page are avoided,
which should make things marginally faster.
Unfortunately python parsers must too be tweaked to handle
entities. This isn't particularly easy: with lxml a custom
Resolver can be used, but the stdlib etree doesn't support
external entities *at all*. So when running without lxml,
the entities are just removed. Right now it doesn't matter,
since the entities are not indexed anyway. But I intend to
add indexing of filenames in the near future, and then the
index generated without lxml might be missing a few lines.
Oh well.
adds test of:
strv_find
strv_find_prefix
strv_overlap
strv_sort
streq_ptr
first_word
Splits tests of util.c into own file to avoid clutter as we add more.
Removed a few prints and uses _cleanup_free_ to make the tests more focused.
This allows us to print simple performance data of all parts of the boot now:
- firmware
- boot loader
- kernel
- initrd
- userspace
This only works for bootloaders which support passing TSC data via EFI
variables. As of now that's only gummiboot.
This saves test output to individual .log files.
The driver is only used in /Makefile.am, not in
/docs/*udev/Makefile.am because the latter don't seem to work with
this driver. They don't produce much output anyway.
.gitignore is alphabetized, and .log files are added to it.
Generated files from /build-aux are removed from the list.
The message catalog can be used to attach short help texts to log lines,
keyed by their MESSAGE_ID= fields. This is useful to help the
administrator understand the context and cause of a message, find
possible solutions and find further related documentation.
Since this is keyed off MESSAGE_ID= this will only work for native
journal messages.
The message catalog supports i18n, and is useful to augment english
language system messages with explanations in the local language.
This commit only includes short explanatory messages for a few example
message IDs, we'll add more complete documentation for the relevant
systemd messages later on.
A service that only sets the scheduling policy to round-robin
fails to be started. This is because the cpu_sched_priority is
initialized to 0 and is not adjusted when the policy is changed.
Clamp the cpu_sched_priority when the scheduler policy is set. Use
the current policy to validate the new priority.
Change the manual page to state that the given range only applies
to the real-time scheduling policies.
Add a testcase that verifies this change:
$ make test-sched-prio; ./test-sched-prio
[test/sched_idle_bad.service:6] CPU scheduling priority is out of range, ignoring: 1
[test/sched_rr_bad.service:7] CPU scheduling priority is out of range, ignoring: 0
[test/sched_rr_bad.service:8] CPU scheduling priority is out of range, ignoring: 100
When traversing entry array chains for a bisection or for retrieving an
item by index we previously always started at the beginning of the
chain. Since we tend to look at the same chains repeatedly, let's cache
where we have been the last time, and maybe we can skip ahead with this
the next time.
This turns most bisections and index lookups from O(log(n)*log(n)) into
O(log(n)). More importantly however, we seek around on disk much less,
which is good to reduce buffer cache and seek times on rotational disks.
Much like logind has a client in loginctl, and journald in journalctl
introduce timedatectl, to change the system time (incl. RTC), timezones
and related settings.

This minimal HTTP server can serve journal data via HTTP. Its primary
purpose is synchronization of journal data across the network. It serves
journal data in three formats:
text/plain: the text format known from /var/log/messages
application/json: the journal entries formatted as JSON
application/vnd.fdo.journal: the binary export format of the journal
The HTTP server also serves a small HTML5 app that makes use of the JSON
serialization to present the journal data to the user.
Examples:
This downloads the journal in text format:
# systemctl start systemd-journal-gatewayd.service
# wget http://localhost:19531/entries
Same for JSON:
# curl -H"Accept: application/json" http://localhost:19531/entries
Access via web browser:
$ firefox http://localhost:19531/
