Many subsystems define own pager_open_if_enabled() function which
checks '--no-pager' command line argument and open pager depends
on its value. All implementations of pager_open_if_enabled() are
the same. Let's merger this function with pager_open() from the
shared/pager.c and remove pager_open_if_enabled() from all subsytems
to prevent code duplication.
Throughout the tree there's spurious use of spaces separating ++ and --
operators from their respective operands. Make ++ and -- operator
consistent with the majority of existing uses; discard the spaces.
The deserialize_timestamp_value() is renamed timestamp_deserialize() to be more
consistent with dual_timestamp_deserialize()
And add the NULL check back on realtime and monotonic
An unlimited quota makes a lot of sense, but we really should try to propagate this onto the loopback file size, since
an infinitely sized file makes no sense.

Issue #2388 suggests the current TasksMax= setting for user processes is to low. Bump it to 12K. Also, bump the
container TasksMax= from 8K to 16K, so that it remains higher than the one for user processes.
(Compare: the kernel default limit for processes system-wide is 32K).

... to determine if color output should be enabled. If the variable is not set,
fall back to using on_tty(). Also, rewrite existing code to use
colors_enabled() where appropriate.
When a unit was started with "systemctl --user" and it failed, error
messages is printed as "systemctl status". But it should be "systemctl
--user status".
The current code is not compatible with current dkr protocols anyway,
and dkr has a different focus ("microservices") than nspawn anyway
("whole machine containers"), hence drop support for it, we cannot
reasonably keep this up to date, and it creates the impression we'd
actually care for the microservices usecase.
GLIB has recently started to officially support the gcc cleanup
attribute in its public API, hence let's do the same for our APIs.
With this patch we'll define an xyz_unrefp() call for each public
xyz_unref() call, to make it easy to use inside a
__attribute__((cleanup())) expression. Then, all code is ported over to
make use of this.
The new calls are also documented in the man pages, with examples how to
use them (well, I only added docs where the _unref() call itself already
had docs, and the examples, only cover sd_bus_unrefp() and
sd_event_unrefp()).
This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we
tend to call our destructors these days.
Note that this defines no public macro that wraps gcc's attribute and
makes it easier to use. While I think it's our duty in the library to
make our stuff easy to use, I figure it's not our duty to make gcc's own
features easy to use on its own. Most likely, client code which wants to
make use of this should define its own:
#define _cleanup_(function) __attribute__((cleanup(function)))
Or similar, to make the gcc feature easier to use.
Making this logic public has the benefit that we can remove three header
files whose only purpose was to define these functions internally.
See #2008.
If we failed to extract a word, then that's how it is, we shouldn't try
to extract it again and again, it's unlikely to work, and we just
deadlock.
This is a fix-up for 52278ad31d.
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.
get_current_dir_name() can return a variety of errors, not just ENOMEM,
hence don't blindly turn its errors to ENOMEM, but return correct errors
in path_make_absolute_cwd().
This trickles down into a couple of other functions, some of which
receive unrelated minor fixes too with this commit.
Previously, we already accepted "-" as special value for dropping
limits. Add "infinity", as that's what we support for RLIMITs and hence
should support here to. Also add "none" as that's what the btrfs tools
use.
With this change we understand more than just leaf quota groups for
btrfs file systems. Specifically:
- When we create a subvolume we can now optionally add the new subvolume
to all qgroups its parent subvolume was member of too. Alternatively
it is also possible to insert an intermediary quota group between the
parent's qgroups and the subvolume's leaf qgroup, which is useful for
a concept of "subtree" qgroups, that contain a subvolume and all its
children.
- The remove logic for subvolumes has been updated to optionally remove
any leaf qgroups or "subtree" qgroups, following the logic above.
- The snapshot logic for subvolumes has been updated to replicate the
original qgroup setup of the source, if it follows the "subtree"
design described above. It will not cover qgroup setups that introduce
arbitrary qgroups, especially those orthogonal to the subvolume
hierarchy.
This also tries to be more graceful when setting up /var/lib/machines as
btrfs. For example, if mkfs.btrfs is missing we don't even try to set it
up as loopback device.
