2014-04-05journalctl: free arg_file on exitZbigniew Jędrzejewski-Szmek
2014-03-18util: replace close_nointr_nofail() by a more useful safe_close()Lennart Poettering
safe_close() automatically becomes a NOP when a negative fd is passed, and returns -1 unconditionally. This makes it easy to write lines like this: fd = safe_close(fd); Which will close an fd if it is open, and reset the fd variable correctly. By making use of this new scheme we can drop a > 200 lines of code that was required to test for non-negative fds or to reset the closed fd variable afterwards.
2014-02-27journalctl: refuse extra arguments with --verify and similarZbigniew Jędrzejewski-Szmek
Positional arguments only make sense with the default action. For other actions, complain instead of ignoring them silently.
2014-02-19make gcc shut upLennart Poettering
If -flto is used then gcc will generate a lot more warnings than before, among them a number of use-without-initialization warnings. Most of them without are false positives, but let's make them go away, because it doesn't really matter.
2014-02-17doc: update punctuationJan Engelhardt
Resolve spotted issues related to missing or extraneous commas, dashes.
2014-01-28always use the same code for creating temporary filesLennart Poettering
Let's unify our code here, and also always specifiy O_CLOEXEC.
2014-01-11journalctl: allow globbing in --unit and --user-unitZbigniew Jędrzejewski-Szmek
This is a continuation of e3e0314b systemctl: allow globbing in commands which take multiple unit names. Multiple patterns can be specified, as separate arguments, or as one argument with patterns seperated by commas. If patterns are given, at least one unit must be matched (by any of the patterns). This is different behaviour than systemctl, but here it is necessary because otherwise anything would be matched, which is unlikely to be the intended behaviour. https://bugs.freedesktop.org/show_bug.cgi?id=59336

2013-12-26journalctl: make sure -b --foobar cannot be misunderstood as --boot=--foobarLennart Poettering
2013-12-26Revert "journalctl: remove unexpected behavior of journalctl -b"Lennart Poettering
This reverts commit cf5bccc2bb9569030cb04debbc4208aaca0fe5b4. We should fix thinks properly if they aren't perfect, not just break other things...
2013-12-25journalctl: remove unexpected behavior of journalctl -bDave Reisner
This flag shouldn't try and consume the following argument. It should behave like every other flag which takes an optional argument when parsed by getopt_long.
2013-12-18journalctl,zsh-completion: fix several issues in --help message textJason St. John
-- fix grammar and reword some descriptions for clarity -- add a useful description of what --follow does -- fix the description for --after-cursor -- properly introduce the FSS acronym for "Forward Secure Sealing" in both sections -- clarify the --disk-usage command [zj: perform similar changes to zsh completions] squash! journalctl: fix several issues in --help message text
2013-12-11journal: pipe journalctl help output into a pagerDjalal Harouni
journalctl help output might run off the screen, so be consistent as other systemd tools do and pipe it into a pager.
2013-12-11journal: add ability to browse journals of running OS containersLennart Poettering
This adds the new library call sd_journal_open_container() and a new "-M" switch to journalctl. Particular care is taken that journalctl's "-b" switch resolves to the current boot ID of the container, not the host.
2013-12-06Get rid of our reimplementation of basenameZbigniew Jędrzejewski-Szmek
The only problem is that libgen.h #defines basename to point to it's own broken implementation instead of the GNU one. This can be fixed by #undefining basename.

2013-11-06clients: unify how we invoke getopt_long()Lennart Poettering
Among other things this makes sure we always expose a --version command and show it in the help texts.
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.
2013-10-13Never call qsort on potentially NULL arraysZbigniew Jędrzejewski-Szmek
This extends 62678ded 'efi: never call qsort on potentially NULL arrays' to all other places where qsort is used and it is not obvious that the count is non-zero.
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
2013-09-10journald: 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.
2013-08-20logs-show: add short-precise mode with us timestampsZbigniew Jędrzejewski-Szmek
Also, always show us timestamps in verbose mode. https://bugzilla.redhat.com/show_bug.cgi?id=991678

2013-08-04systemd-delta: Only print colors when on a ttyDaniel Schaal
This make systemd-delta follow the behaviour of systemctl and journalctl. https://bugs.freedesktop.org/show_bug.cgi?id=67656 [zj: unify color query methods between those three programs.]
2013-07-26journalctl: use _COMM= match for scriptsZbigniew Jędrzejewski-Szmek
In case of scripts, _EXE is set to the interpreter name, and _COMM is set based on the file name. Add a match for _COMM, and _EXE if the interpreter is not a link (e.g. for yum, the interpreter is /usr/bin/python, but it is a link to /usr/bin/python2, which in turn is a link to /usr/bin/python2.7, at least on Fedora, so we end up with _EXE=/usr/bin/python2.7). I don't think that such link chasing makes sense, because the final _EXE name is more likely to change.

2013-07-18journalctl: fix signedness warning and boot-id syntax checkZbigniew Jędrzejewski-Szmek
2013-07-17journalctl: remove ":" from the --boot syntaxZbigniew Jędrzejewski-Szmek
Instead of :-0, :1, :5, etc., use -0, 1 or +1, 5, etc. For BOOT_ID+OFFSET, use BOOT_ID+offset or BOOT_ID-offset (either + or - is required). Also make error handling a bit more robust and verbose. Modify the man page to describe the most common case (-b) first, and the second most common case (-b -1) second.

2013-07-16journalctl: augment short mode with a cursor at the endZbigniew Jędrzejewski-Szmek
Two options are added: --show-cursor to print the cursor at the end, and --after-cursor to resume logs on the next line after the previous one.
2013-07-16journalctl: Add support for showing messages from a previous bootJan Janssen
Hi, I redid the boot ID look up to use enumerate_unique. This is quite fast if the cache is warm but painfully slow if it isn't. It has a slight chance of returning the wrong order if realtime clock jumps around. This one has to do n searches for every boot ID there is plus a sort, so it depends heavily on cache hotness. This is in contrast to the other way of look-up through filtering by a MESSAGE_ID, which only needs about 1 seek + whatever amount of relative IDs you want to walk. I also have a linked-list + (in-place) mergesort version of this patch, which has pretty much the same runtime. But since this one is using libc sorting and armortized allocation, I prefer this one. To summarize: The MESSAGE_ID way is a *lot* faster but can be incomplete due to rotation, while the enumerate+sort will find every boot ID out there but will be painfully slow for large journals and cold caches. You choose :P Jan

2013-06-10journalctl: allow the user to specify the file(s) to useZbigniew Jędrzejewski-Szmek
This is useful for debugging and feels pretty natural. For example answering the question "is this big .journal file worth keeping?" is made easier.
2013-06-10journalctl: no color for --reboot-- when not on ttyZbigniew Jędrzejewski-Szmek
2013-06-10journalctl: add --system/--user flagsZbigniew Jędrzejewski-Szmek
--user basically gives messages from your own systemd --user services. --system basically gives messages from PID 1, kernel, and --system services. Those two options are not exahustive, because a priviledged user might be able to see messages from other users, and they will not be shown with either or both of those flags.
2013-06-09journalctl: fix verbose output when no logs are foundZbigniew Jędrzejewski-Szmek
$ journalctl -o verbose _EXE=/quiet/binary -f -- Logs begin at Sun 2013-03-17 17:28:22 EDT. -- Failed to get realtime timestamp: Cannot assign requested address JOURNAL_FOREACH_DATA_RETVAL is added, which allows the caller to get the return value from sd_journal_enumerate_data. I think we might want to expose this macro like SD_JOURNAL_FOREACH_DATA, but for now it is in journal-internal.h. There's a change in behaviour for output_*, not only in output_verbose, that errors in sd_j_enumerate_data are not silently ignored anymore. https://bugs.freedesktop.org/show_bug.cgi?id=56459
2013-06-04systemctl: limit logs in status to current bootZbigniew Jędrzejewski-Szmek
Also reworded a few debug messages for brevity, and added a log statement which prints out the filter at debug level: Journal filter: (((UNIT=sys-module-configfs.device AND _PID=1) OR (COREDUMP_UNIT=sys-module-configfs.device AND MESSAGE_ID=fc2e22bc6ee647b6b90729ab34a250b1) OR _SYSTEMD_UNIT=sys-module-configfs.device) AND _BOOT_ID=4e3c518ab0474c12ac8de7896fe6b154)

2013-04-17journalctl: specify "--unit=" and "--user-unit" multiple timesHarald Hoyer
Previously only one "--unit=" or "--user-unit" could be specified. With this patch, journalcrtl can show multiple units. $ journalctl -u systemd-udevd.service -u sshd.service -u crond.service -b -- Logs begin at Sa 2013-03-23 11:08:45 CET, end at Fr 2013-04-12 09:10:22 CEST. -- Apr 12 08:41:37 lenovo systemd[1]: Started udev Kernel Device Manager.

2013-04-17journal: add one more level on top with ANDHarald Hoyer
When using "-p" and "-b" in combination with "-u", the output is not what you would expect. The reason is the sd_journal_add_disjunction() call in add_matches_for_unit() and add_matches_for_user_unit(), which adds two ORs without taking the other conditions to every OR. Adding another level on top with AND and sd_journal_add_conjunction() solves the problem. Output before: $ journalctl -o short-monotonic -ab -p 0 -u sshd.service -- Reboot -- [ 3.216305] lenovo systemd[1]: Starting OpenSSH server daemon... -- Reboot -- [ 3.168666] lenovo systemd[1]: Starting OpenSSH server daemon...

2013-04-17journalctl: show fields requested with --field in fullZbigniew Jędrzejewski-Szmek
I see little point in silently truncating fields when they are explictly requested. With this change e.g. journalctl -b MESSAGE_ID=9f26aa562cf440c2b16c773d0479b518 --field=BOOTCHART works as expected.

2013-04-04journal: add public API call sd_journal_get_events()Lennart Poettering
This function should be used when filling in "struct pollfd"'s .events field for watching the journal. It will always return POLLIN for now, but we should keep our options open to change this later on. This mimics libsystemd-bus' sd_bus_get_events() call with the same purpose.
2013-04-04util: make time formatting a bit smarterLennart Poettering
Instead of outputting "5h 55s 50ms 3us" we'll now output "5h 55.050003s". Also, while outputting the accuracy is configurable. Basically we now try use "dot notation" for all time values > 1min. For >= 1s we use 's' as unit, otherwise for >= 1ms we use 'ms' as unit, and finally 'us'. This should give reasonably values in most cases.
2013-04-03util: rename parse_usec() to parse_sec() sinds the default unit is secondsLennart Poettering
Internally we store all time values in usec_t, however parse_usec() actually was used mostly to parse values in seconds (unless explicit units were specified to define a different unit). Hence, be clear about this and name the function about what we pass into it, not what we get out of it.
