2013-12-03journal: fail silently in sd_j_sendv() if journal is unavailableZbigniew Jędrzejewski-Szmek
"syslog(3) and sd_journal_print() may largely be used interchangeably functionality-wise" according to sd_journal_print(3). This socket should be always available except in rare circumstatances, and we don't random applications to fail on logging, so let's do what syslog did. The alternative of forcing all callers to do error handling for this rare case doesn't really have any benefits, since if they can't log there isn't much they can do anyway. https://bugzilla.redhat.com/show_bug.cgi?id=1023041

2013-11-27journal: simplify pre-allocation logicLennart Poettering
let's just do a single fallocate() as far as possible, and don't distuingish between allocated space and file size. This way we can save a syscall for each append, which makes quite some benefits.

This way we can do a quick restart limiting a bit how wildly we need to jump around during the bisection process.

2013-11-25conf-parser: distinguish between multiple sections with the same nameTom Gundersen
Pass on the line on which a section was decleared to the parsers, so they can distinguish between multiple sections (if they chose to). Currently no parsers take advantage of this, but a follow-up patch will do that to distinguish [Address] Address=192.168.0.1/24 Label=one [Address] Address=192.168.0.2/24 Label=two from [Address] Address=192.168.0.1/24 Label=one Address=192.168.0.2/24 Label=two

2013-11-13journal: timestamp support on console messagesUmut Tezduyar Lindskog
journald mimics the kernel here: timestamps will be printed if /sys/module/printk/parameters/time contains "Y".
2013-11-12bus: introduce concept of a default bus for each thread and make use of it ↵Lennart Poettering
everywhere We want to emphasize bus connections as per-thread communication primitives, hence introduce a concept of a per-thread default bus, and make use of it everywhere.
2013-11-08Remove dead code and unexport some callsLennart Poettering
"make check-api-unused" informs us about code that is not used anymore or that is exported but only used internally. Fix these all over the place.

Among other things this makes sure we always expose a --version command and show it in the help texts.

Instead of individually checking for containers in each user do this once in a new call proc_cmdline() that read the file only if we are not in a container.
2013-10-28journalctl: add --list-boots to show boot IDs and timesZbigniew Jędrzejewski-Szmek
Suggested by David Wilkins <dwilkins@maths.tcd.ie> in https://bugzilla.redhat.com/show_bug.cgi?id=967521: > [Specific boot ID is a] bit of a palaver to obtain. I consulted the > verbose dump of the journal to discover the _BOOT_ID for the > timestamp, and then generated the journal dump for that boot using > journalctl _BOOT_ID=foo -o short-monotonic.
2013-10-16timedated: use libsystemd-bus instead of libdbus for bus communicationLennart Poettering
Among other things this also adds a few things necessary for the change: - Considerably more powerful error returning APIs in libsystemd-bus - Adapter for connecting an sd_bus to an sd_event - As I reworked the PolicyKit logic to the new library I also made it asynchronous, so that PolicyKit requests of one user cannot block out another user anymore. - We always use the macro names for common bus error. That way it is harder to mistype them since the compiler will notice

Always use our own macros, and name all our own macros the same style.
2013-10-14list: make our list macros a bit easier to use by not requring type spec on ↵Lennart Poettering
each invocation We can determine the list entry type via the typeof() gcc construct, and so we should to make the macros much shorter to use.
2013-10-14util: allow trailing semicolons on define_trivial_cleanup_func linesLennart Poettering
Emacs C indenting really gets confused by these lines if they carry no trailing semicolon, hence let's make this nicer for good old emacs. The other macros which define functions already do this too, so let's copy the scheme here. Also, let's use an uppercase name for the macro. So far our rough rule was that macros that are totally not function-like (like this ones, which define a function) are uppercase. (Well, admittedly it is a rough rule only, for example function and variable decorators are all lower-case SINCE THE CONSTANT YELLING IN THE SOURCES WOULD SUCK, and also they at least got underscore prefixes.) Also, the macros that define functions that we already have are all uppercase, so let's do the same here...

2013-10-13Fix write-only use of a few variablesZbigniew Jędrzejewski-Szmek
Since the invention of read-only memory, write-only memory has been considered deprecated. Where appropriate, either make use of the value, or avoid writing it, to make it clear that it is not used.

2013-10-09journald: remove rotated file from hashmap when rotation failsZbigniew Jędrzejewski-Szmek
Before, when the user journal file was rotated, journal_file_rotate could close the old file and fail to open the new file. In that case, we would leave the old (deallocated) file in the hashmap. On subsequent accesses, we could retrieve this stale entry, leading to a segfault. When journal_file_rotate fails with the file pointer set to 0, old file is certainly gone, and cannot be used anymore. https://bugzilla.redhat.com/show_bug.cgi?id=890463

2013-10-07journalctl: flip to --full by defaultZbigniew Jędrzejewski-Szmek
We already shew lines in full when using a pager or not on a tty. The commit disables ellipsization in the sole remaining case, namely when --follow is used. This has been a popular request for a long time, and indeed, full output seems much more useful. Old behaviour can still be requested by using --no-full. Old options retain their behaviour for compatiblity, but aren't advertised as much. This change applies only to jornalctl, not to systemctl, when ellipsization is useful to keep the layout. https://bugzilla.redhat.com/show_bug.cgi?id=984758

2013-09-17journald: avoid NSS in journaldLennart Poettering
In order to avoid a deadlock between journald looking up the "systemd-journal" group name, and nscd (or anyother NSS backing daemon) logging something back to the journal avoid all NSS in journald the same way as we avoid it from PID 1. With this change we rely on the kernel file system logic to adjust the group of created journal files via the SETGID bit on the journal directory. To ensure that it is always set, even after the user created it with a simply "mkdir" on the shell we fix it up via tmpfiles on boot.
2013-09-17journald: log the slice of a process along with each message in _SYSTEMD_SLICE=Lennart Poettering
2013-09-12journald: Log error when failed to get machine-id on startOlivier Brunel
Can help since the journal requires /etc/machine-id to exists in order to start, and will simply silently exit when it does not.
2013-09-10journald: be a bit more verbose when vacuumingZbigniew Jędrzejewski-Szmek
Vacuuming behaviour is a bit confusing, and/or we have some bugs, so those additional messages should help to find out what's going on. Also, rotation of journal files shouldn't be happening too often, so the level of the messages is bumped to info, so that they'll be logged under normal operation.
2013-09-06systemd-coredump: Log crashes without coredumps on failureAndrew Cook
Make a best-effort attempt to store information about crashes during failure, currently if these are encountered the crash is completely silenced. ideally coredumpctl would show if a coredump is available.
2013-09-06systemd-coredump: Ignore coredumps larger than COREDUMP_MAXAndrew Cook
Currently this check happens when the coredump has been collected in it's entirety and being received by journald. this is not ideal behaviour when the crashing process is consuming significant percentage of physical memory such as a large instance of firefox or a java application.
2013-09-06journald: fix fd leak in journal_file_emptyGeorge McCollister
Before my previous patch, journal_file_empty wasn't be called with the correct filename. Now that it's being called with the correct filename it leaks file descriptors. This patch closes the file descriptors before returning. Signed-off-by: George McCollister <george.mccollister@gmail.com> [Edit harald@redhat.com: make use of _cleanup_close_ instead]
2013-09-06journald: fix vacuuming of archived journalsGeorge McCollister
d_name is modified on line 227 so if the entire journal name is needed again p must be used. Before this change when journal_file_empty was called on archived journals it would always return with -2. Signed-off-by: George McCollister <george.mccollister@gmail.com>
