Introduce a dedicated helper in order to reset the storage space cache.
|
|
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.

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.

Use mfree more and add another function to simplify a common set&free pattern
|
|
|
|
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.

Also rewrap some comments so that they don't have a very long line and a very
short line.

In certain situations drop-ins in /usr/lib/ are useful, for example when one package
wants to modify the behaviour of another package, or the vendor wants to tweak some
upstream unit without patching.
Drop-ins in /run are useful for testing, and may also be created by systemd itself.
Follow-up for the discussion in #2103.

legacy hierarchy (#4269)
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.

Let's just say that the journal takes up space in the file system, not on disk,
as tmpfs is definitely a file system, but not a disk.
Fixes: #4059
|
|
Never permit that we write to journal files that have newer timestamps than our
local wallclock has. If we'd accept that, then the entries in the file might
end up not being ordered strictly.
Let's refuse this with ETXTBSY, and then immediately rotate to use a new file,
so that each file remains strictly ordered also be wallclock internally.
|
|
As soon as we notice that the clock jumps backwards, rotate journal files. This
is beneficial, as this makes sure that the entries in journal files remain
strictly ordered internally, and thus the bisection algorithm applied on it is
not confused.
This should help avoiding borked wallclock-based bisection on journal files as
witnessed in #4278.
|
|
Let's use the earliest linearized event timestamp for journal entries we have:
the event dispatch timestamp from the event loop, instead of requerying the
timestamp at the time of writing.
This makes the time a bit more accurate, allows us to query the kernel time one
time less per event loop, and also makes sure we always use the same timestamp
for both attempts to write an entry to a journal file.

When iterating through partially synced journal files we need to be prepared
for hitting with invalid entries (specifically: non-initialized). Instead of
generated an error and giving up, let's simply try to preceed with the next one
that is valid (and debug log about this).
This reworks the logic introduced with caeab8f626e709569cc492b75eb7e119076059e7
to iteration in both directions, and tries to look for valid entries located
after the invalid one. It also extends the behaviour to both iterating through
the global entry array and per-data object entry arrays.
Fixes: #4088

Let's make dissecting of borked journal files more expressive: if we encounter
an object whose first 8 bytes are all zeroes, then let's assume the object was
simply never initialized, and say so.
Previously, this would be detected as "overly short object", which is true too
in a away, but it's a lot more helpful printing different debug options for the
case where the size is not initialized at all and where the size is initialized
to some bogus value.
No function behaviour change, only a different log messages for both cases.
|
|
Let's and extra check, reusing check_properly_ordered() also for
journal_file_next_entry_for_data().
|
|
This adds a new call check_properly_ordered(), which we can reuse later, and
makes the code a bit more readable.
|
|
This allows us to share a bit more code between journal_file_next_entry() and
journal_file_next_entry_for_data().
|
|
Let's make it easier to figure out when we see an invalid journal file, why we
consider it invalid, and add some minimal debug logging for it.
This log output is normally not seen (after all, this all is library code),
unless debug logging is exlicitly turned on.

When date is changed in system to future and normal user logs to new journal file, and then date is changed back to present time, the "journalctl --list-boot" command goes to forever loop. This commit tries to fix this problem by checking first the boot id list if the found boot id was already in that list. If it is found, then stopping the boot id find loop.
