2015-01-08loginctl: show the 10 most recent log user/session log lines in "loginctl ↵Lennart Poettering
user-status" and "loginctl session-status"
2015-01-06tree-wide: remove unnecessary LOG_PRIZbigniew Jędrzejewski-Szmek
LOG_DEBUG is already a log level, there is no need to use LOG_PRI which is for filtering out the facility.
2014-11-28treewide: a few more log_*_errno + return simplificationsMichal Schmidt
The one in tmpfiles.c:create_item() even looks like it fixes a bug.
2014-11-28treewide: yet more log_*_errno + return simplificationsMichal Schmidt
Using: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg; print;' $f done And a couple of manual whitespace fixups.
2014-11-28treewide: more log_*_errno() conversions, multiline callsMichal Schmidt
Basically: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/log_(debug|info|notice|warning|error|emergency)\("([^"]*)%s"([^;]*),\s*strerror\(-?([->a-zA-Z_]+)\)\);/log_\1_errno(\4, "\2%m"\3);/gms;print;' \ $f; done Plus manual indentation fixups.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
2014-11-04journal: when dumping log data with missing COMM fields, show "unknown" insteadLennart Poettering
A small readability improvement...
2014-10-22machine: validate machine names using machine_name_is_valid() instead of ↵Lennart Poettering
string_is_safe() After all, we know have this as generic validator, so let's be correct and use it wherver applicable.
2014-10-08time: functions named "internal" really shouldn't be exportedLennart Poettering
Also, let's try to make function names descriptive, instead of using bools for flags.
2014-10-03journalctl: make --utc work everywhereJan Synacek
The --utc option was introduced by commit 9fd290443f5f99fca0dcd4216b1de70f7d3b8db1. Howerver, the implementation was incomplete.
2014-10-02journalctl: add --utc optionJan Synacek
Introduce option to display time in UTC.
2014-09-15hashmap: introduce hash_ops to make struct Hashmap smallerMichal Schmidt
It is redundant to store 'hash' and 'compare' function pointers in struct Hashmap separately. The functions always comprise a pair. Store a single pointer to struct hash_ops instead. systemd keeps hundreds of hashmaps, so this saves a little bit of memory.

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.
2014-03-13systemctl: suppress duplicate newline if there's not log output in ↵Lennart Poettering
"systemctl status"
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
2013-12-23bus: when getting a kdbus connection into a container wait first for child, ↵Lennart Poettering
then read message There's no EOF generated for AF_UNIX/SOCK_DGRAM sockets, hence let's wait for the child first to see if it succeeded, only then read the socket.
2013-12-17bus: when entering an existing namespace to connect to a container's system ↵Lennart Poettering
bus also switch over PID namespace This is necessary to ensure that kdbus can collect creds of the destination namespace when connecting.

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...

2013-08-11logs-show: fix indentation for 2nd and later lines, show lines in fullZbigniew Jędrzejewski-Szmek
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.

Replace mallocs with alloca while at it.
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

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.
