2014-04-05journal: fix export of messages containing newlinesZbigniew Jędrzejewski-Szmek
In "export" format, newlines are significant, and messages containing newlines must be exported as "binary".
2014-03-24util: replace close_pipe() with new safe_close_pair()Lennart Poettering
safe_close_pair() is more like safe_close(), except that it handles pairs of fds, and doesn't make and misleading allusion, as it works similarly well for socketpairs() as for pipe()s...
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.

2014-02-27logs-show: fix corrupt output with empty messagesUoti Urpala
If a message had zero length, journalctl would print no newline, and two output lines would be concatenated. Fix. The problem was introduced in commit 31f7bf199452 ("logs-show: print multiline messages"). Affected short and verbose output modes. Before fix: Feb 09 21:16:17 glyph dhclient[1323]: Feb 09 21:16:17 glyph NetworkManager[788]: <info> (enp4s2): DHCPv4 state changed nbi -> preinit after: Feb 09 21:16:17 glyph dhclient[1323]: Feb 09 21:16:17 glyph NetworkManager[788]: <info> (enp4s2): DHCPv4 state changed nbi -> preinit

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.

2013-09-13Advertise hibernation only if there's enough free swapZbigniew Jędrzejewski-Szmek
Condition that is checked is taken from upower: active(anon) < free swap * 0.98 This is really stupid, because the kernel knows the situation better, e.g. there could be two swap files, and then hibernation would be impossible despite passing this check, or the kernel could start supporting compressed swap and/or compressed hibernation images, and then this this check would be too stringent. Nevertheless, until we have something better, this should at least return a true negative if there's no swap. Logging of capabilities in the journal is changed to not strip leading zeros. I consider this more readable anyway. http://cgit.freedesktop.org/upower/tree/src/up-daemon.c#n613 https://bugzilla.redhat.com/show_bug.cgi?id=1007059

2013-08-21logs-show: fix condition for ellipsizing multi-line messagesZbigniew Jędrzejewski-Szmek
falconindy> the ellipsizing seems a bit wrong here.... I got a bit carried away with putting dots everywhere :)
2013-08-20logs-show: show source timestamp in verbose modeZbigniew Jędrzejewski-Szmek
This makes verbose behave like short mode, i.e. try to show the source timestamp, and fall back to journald timestamp only if unavailable or unparsable. I think verbose should be like short, only showing more fields, and showing different timestamps would be confusing.
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
2013-08-11logs-show: limit to 3 lines and use dots if not showing full messageZbigniew Jędrzejewski-Szmek
So far, we would show up to 128 bytes from a message, simply cutting of the rest. With multiline messages, it is quite common for a message to be longer than that, and this model doesn't really work anymore. A new limit is added: up to 3 lines will be shown, unless --full is used (c.f. first line below). The limit for bytes is extended to 300 bytes. An ellipsis will always be used, if some form of truncation occurs. If the tail of the message is cut off, either because of length or line limit, dots will be shown at the end of the last line. If this last line is short, the dots will be simply appended. If the last line is too long for that, it will be ellipsized with dots at the very end. Note that the limits are in bytes, not characters, and we suck at outputting unicode strings (c.f. last three lines below). Aug 11 10:46:21 fedora python[67]: test message line line...

Now --full will show long fields in full, like it already did with --all.

2013-06-26journalctl: highlight MESSAGE= in verbose outputZbigniew Jędrzejewski-Szmek
When looking at verbose output, additional "work" is required to pick out the interesting MESSAGE= lines from all the fields. Also, show long fields in full in verbose output mode when OUTPUT_FULL_WIDTH is specified.

2013-06-20Make sure we only show authentic coredump messagesZbigniew Jędrzejewski-Szmek
Before we only checked the MESSAGE_ID and COREDUMP_UNIT. Those are both user-controlled fields. For COREDUMP_USER_UNIT, relax the rules a bit, and also allow messages from _UID=0.

2013-06-20journalctl: show lines in full with --allZbigniew Jędrzejewski-Szmek
In 31f7bf1 "logs-show: print multiline messages", I forgot to take into account the fact that --all implies --full for journalctl.
2013-06-10journal: add ability to filter by current userZbigniew Jędrzejewski-Szmek
This is the just the library part. SD_JOURNAL_CURRENT_USER flags is added to sd_j_open(), to open files from current user. SD_JOURNAL_SYSTEM_ONLY is renamed to SD_JOURNAL_SYSTEM, and changed to mean to (also) open system files. This way various flags can be combined, which gives them nicer semantics, especially if other ones are added later. Backwards compatibility is kept, because SD_JOURNAL_SYSTEM_ONLY is equivalent to SD_JOURNAL_SYSTEM if used alone, and before there we no other 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

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)

2013-04-16macro: rework how we define cleanup macrosLennart Poettering
There's now a generic _cleanup_ macro with an argument. The macros for specific types are now defined using this macro, and in the header files where they belong. All cleanup handlers are now inline functions.

2013-03-13logs-show: export logic to add matches for unitsZbigniew Jędrzejewski-Szmek
After that functions which add matches, show_journal_by_unit and show_journal_by_user_unit, become nearly identical, so I merged them into one function.
2013-02-07logs-show: show messages for all unit types in systemctl statusMirco Tischler
I can't find a reason why we shouldn't try to output messages for other unit types than .service, .socket, .mount and .swap as well. It's probably a leftover from before we started logging UNIT= from inside PID 1.

2012-11-21journal: by default do not decompress dat objects larger than 64KLennart Poettering
This introduces a new data threshold setting for sd_journal objects which controls the maximum size of objects to decompress. This is relieves the library from having to decompress full data objects even if a client program is only interested in the initial part of them. This speeds up "systemd-coredumpctl" drastically when invoked without parameters.
2012-11-15journal: implement message catalogLennart Poettering
The message catalog can be used to attach short help texts to log lines, keyed by their MESSAGE_ID= fields. This is useful to help the administrator understand the context and cause of a message, find possible solutions and find further related documentation. Since this is keyed off MESSAGE_ID= this will only work for native journal messages. The message catalog supports i18n, and is useful to augment english language system messages with explanations in the local language. This commit only includes short explanatory messages for a few example message IDs, we'll add more complete documentation for the relevant systemd messages later on.

2012-09-05journalctl: rework JSON output modeLennart Poettering
This splits the JSON output mode into different modes: json and json-pretty. The former printing one entry per line, the latter showing JSON objects nicely indented and in multiple lines to make it easier to read for humans.
2012-09-03shared: logs-show: fflush after each output typeBrandon Philips
journalctl -f redirected to a pipe or file wasn't working for some output formats but was working for json. It turns out only json was doing an fflush. Make all output formats flush.
