Since we ignore the result anyway, downgrade errors to warning.
log_oom() will still emit an error, but that's mostly theoretical, so it
is not worth complicating the code to avoid the small inconsistency
Now that determine_space_for() only deals with storage space (cached) values,
rename it so it reflects the fact that only the cached storage space values are
updated.
Updating min_use is rather an unusual operation that is limited when we first
open the journal files, therefore extracts it from determine_space_for() and
create a function of its own and call this new function when needed.
determine_space_for() is now dealing with storage space (cached) values only.
There should be no functional changes.
The set of storage space values we cache are calculated according to a couple
of filesystem statistics (free blocks, block size).
This patch caches the vfs stats we're interested in so these values are
available later and coherent with the rest of the space cached values.
This patch makes system_journal_open() stop emitting the space usage
message. The caller is now free to emit this message when appropriate.
When restarting the journal, we can now emit the message *after*
flushing the journal (if required) so that all flushed log entries are
written in the persistent journal *before* the status message.
This is required since the status message is always younger than the
flushed entries.
Fixes#4190.
This commit simply extracts from determine_space_for() the code which emits the
storage usage message and put it into a function of its own so it can be reused
by others paths later.
No functional changes.
This structure keeps track of specificities for a given journal type
(persistent or volatile) such as metrics, name, etc...
The cached space values are now moved in this structure so that each
journal has its own set of cached values.
Previously only one set existed and we didn't know if the cached
values were for the runtime journal or the persistent one.
When doing:
determine_space_for(s, runtime_metrics, ...);
determine_space_for(s, system_metrics, ...);
the second call returned the cached values for the runtime metrics.
This commit simply extracts from determine_space_for() the code which
determines the FS usage where the passed path lives (statvfs(3)) and put it
into a function of its own so it can be reused by others paths later.
No functional changes.
When a unit file is invalid, we'd return an error without any details:
$ systemctl --root=/ enable testing@instance.service
Failed to enable: Invalid argument.
Fix things to at least print the offending file name:
$ systemctl enable testing@instance.service
Failed to enable unit: File testing@instance.service: Invalid argument
$ systemctl --root=/ enable testing@instance.service
Failed to enable unit, file testing@instance.service: Invalid argument.
A real fix would be to pass back a proper error message from conf-parser.
But this would require major surgery, since conf-parser functions now
simply print log errors, but we would need to return them over the bus.
So let's just print the file name, to indicate where the error is.
(Incomplete) fix for #4210.
Test case:
[Install]
WantedBy= default.target
Also=foobar-unknown.service
Before:
$ systemctl --root=/ enable testing2@instance.service
Failed to enable: No such file or directory.
After
$ ./systemctl --root=/ enable testing2@instance.service
Failed to enable unit, file foobar-unknown.service: No such file or directory.
With the following test case:
[Install]
WantedBy= default.target
Also=foobar-unknown.service
disabling would fail with:
$ ./systemctl --root=/ disable testing.service
Cannot find unit foobar-unknown.service. # this is level debug
Failed to disable: No such file or directory. # this is the error
After the change we proceed:
$ ./systemctl --root=/ disable testing.service
Cannot find unit foobar-unknown.service.
Removed /etc/systemd/system/default.target.wants/testing.service.
This does not affect specifying a missing unit directly:
$ ./systemctl --root=/ disable nosuch.service
Failed to disable: No such file or directory.
This commit adds a `fd` option to `StandardInput=`,
`StandardOutput=` and `StandardError=` properties in order to
connect standard streams to externally named descriptors provided
by some socket units.
This option looks for a file descriptor named as the corresponding
stream. Custom names can be specified, separated by a colon.
If multiple name-matches exist, the first matching fd will be used.
When the unit that is triggered by a timer is started and running,
we transition to "running" state, and the timer will not elapse again
until the unit has finished running. In this state "systemctl list-timers"
would display the previously calculated next elapse time, which would
now of course be in the past, leading to nonsensical values.
Simply set the next elapse to infinity, which causes list-timers to
show n/a. We cannot specify when the next elapse will happen, possibly
never.
Fixes#4031.
It is allowed for unit files to have an mtime==0, so instead of assuming that
any file that had mtime==0 was masked, use the load_state to filter masked
units.

It's a common pattern, so add a helper for it. A macro is necessary
because a function that takes a pointer to a pointer would be type specific,
similarly to cleanup functions. Seems better to use a macro.
There are overlapping control group resource settings for the unified and
legacy hierarchies. To help transition, the settings are translated back and
forth. When both versions of a given setting are present, the one matching the
cgroup hierarchy type in use is used. Unfortunately, this is more confusing to
use and document than necessary because there is no clear static precedence.
Update the translation logic so that the settings for the unified hierarchy are
always preferred. systemd.resource-control man page is updated to reflect the
change and reorganized so that the deprecated settings are at the end in its
own section.
