2016-10-19journal: rename determine_space_for() into cache_space_refresh()Franck Bui
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.
2016-10-19journal: introduce patch_min_use() helperFranck Bui
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.
2016-10-19journal: introduce cache_space_invalidate()Franck Bui
Introduce a dedicated helper in order to reset the storage space cache.
2016-10-19journal: cache used vfs stats as wellFranck Bui
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.
2016-10-19journal: don't emit space usage message when opening the journal (#4190)Franck Bui
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.
2016-10-19journal: introduce server_space_usage_message()Franck Bui
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.
2016-10-19journal: introduce JournalStorage and JournalStorageSpace structuresFranck Bui
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.
2016-10-19journal: introduce determine_path_usage()Franck Bui
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.
2016-10-18shared/install: report invalid unit files slightly betterZbigniew Jędrzejewski-Szmek
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.
2016-10-18shared/install: resolve specifiers in Also=Zbigniew Jędrzejewski-Szmek
Test case: [Install] WantedBy= default.target Also=getty@%p.service $ ./systemctl --root=/ enable testing@instance.service Created symlink /etc/systemd/system/default.target.wants/testing@instance.service → /etc/systemd/system/testing@.service. Created symlink /etc/systemd/system/getty.target.wants/getty@testing.service → /usr/lib/systemd/system/getty@.service. $ ./systemctl --root=/ disable testing@instance.service Removed /etc/systemd/system/getty.target.wants/getty@testing.service. Removed /etc/systemd/system/default.target.wants/testing@instance.service. Fixes part of #4210. Resolving specifiers in DefaultInstance seems to work too: [Install] WantedBy= default.target DefaultInstance=%u $ systemctl --root=/ enable testing3@instance.service Created symlink /etc/systemd/system/default.target.wants/testing3@instance.service → /etc/systemd/system/testing3@.service. $ systemctl --root=/ enable testing3@.service Created symlink /etc/systemd/system/default.target.wants/testing3@zbyszek.service → /etc/systemd/system/testing3@.service.
2016-10-18shared/install: provide more info if install_info_traverse_failsZbigniew Jędrzejewski-Szmek
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.
2016-10-18shared/install: in install_context_mark_for_removal ignore not found unitsZbigniew Jędrzejewski-Szmek
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.

2016-10-17core/exec: add a named-descriptor option ("fd") for streams (#4179)Luca Bruno
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.

2016-10-17core/timer: reset next_elapse_*time when timer is not waitingZbigniew Jędrzejewski-Szmek
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.
2016-10-17pid1: do not use mtime==0 as sign of masking (#4388)Zbigniew Jędrzejewski-Szmek
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. Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1384150.

2016-10-16tree-wide: introduce free_and_replace helperZbigniew Jędrzejewski-Szmek
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.

2016-10-14core: make settings for unified cgroup hierarchy supersede the ones for ↵Tejun Heo
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.

2016-10-12journal: refuse opening journal files from the future for writingLennart Poettering
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.
2016-10-12journald: automatically rotate journal files when the clock jumps backwardsLennart Poettering
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.
2016-10-12journald: use the event loop dispatch timestamp for journal entriesLennart Poettering
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.
