c7b17836ea Implement devices/global_filter.
The global filter is applied first, and is also applied in pvscan --cache (which
is called from udev rules to keep lvmetad updated). Cf. example.conf.

ea14d5159c libdaemon: Extend and refactor APIs.
- move common dm_config_tree manipulation functions from lvmetad-core to
  daemon-shared
- add config-tree-based request manipulation APIs to daemon-client
- factor out _v (va_list) variants of most variadic functions in libdaemon

b61be64370 libdaemon: Draft logging infrastructure.
- logging is not controlled by "levels" but by "types"; types are
  independent of each other... implementation of the usual "log level"
  user-level semantics can be simply done on top; the immediate
  application is enabling/disabling wire traffic logging independently
  of other debug data, since the former is rather bulky and can easily
  obscure almost everything else
- all logs go to "outlets", of which we currently have 2: syslog and
  stderr; which "types" go to which "outlets" is entirely configurable

8d5ae472e5 daemon-server: fix error message on daemon shutdown
If a daemon (like lvmetad that is using common daemon-server code)
received a kill signal that was supposed to shut the daemon down,
a spurious message was issued: "Failed to handle a client connection".

This happened if the kill signal came just in the middle of waiting
for a client request in "select" - the request that was supposed to
be handled was blank at that moment of course.

6f3cd63551 cleanup: replace memset with struct initilization
Simplifies the code, properly detects too long socket paths,
drops unused parameter.

bf29fa49d3 Use dm_strncpy instead of plain strncpy while setting the socket path.
Also check the return value as it meaningless to work with truncated strings.

761407217a Do exit if LISTEN_PID environment variable not correct during systemd handover. 2012-03-16 21:30:53 +00:00

93945bb616 Use SD_ACTIVATION env. var. in systemd units to better detect systemd in use.
LISTEN_PID and LISTEN_FDS environment variables are defined only during systemd
"start" action. But we still need to know whether we're activated during
"reload" action as well - we use the reload action to call "dmeventd -R"/"lvmetad -R"
for statefull daemon restart. We can't use normal "restart" as that is simply
composed of "stop" and "start" and we would lose any state the daemon has.
