2015-03-10logs-show: fix check of loop_read_exactThomas Hindoe Paaboel Andersen
just a typo fix
2015-03-09Introduce loop_read_exact helperZbigniew Jędrzejewski-Szmek
Usually when using loop_read(), we want to read the full buffer. Add a helper that mirrors loop_write(), and returns 0 when full buffer was read, and an error otherwise. Use -ENODATA for the short read, to distinguish it from a read error.
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-12include <poll.h> instead of <sys/poll.h>Thomas Hindoe Paaboel Andersen
include-what-you-use automatically does this and it makes finding unnecessary harder to spot. The only content of poll.h is a include of sys/poll.h so should be harmless.
2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.
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...

2013-06-26journalctl: 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.
