tree-wide: remove Emacs lines from all files This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

shared: include what we use The next step of a general cleanup of our includes. This one mostly adds missing includes but there are a few removals as well.

tree-wide: sort includes in *.h This is a continuation of the previous include sort patch, which only sorted for .c files.

remove unused includes 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.

loginctl: show the 10 most recent log user/session log lines in "loginctl user-status" and "loginctl session-status"

Always prefer our headers to system headers In practice this shouldn't make much difference, but sometimes our headers might be newer, and we want to test them.

journal: add ability to browse journals of running OS containers 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.

systemctl: show hint about --full when lines don't fit

systemctl: limit logs in status to current boot 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)

Add __attribute__((const, pure, format)) in various places I'm assuming that it's fine if a _const_ or _pure_ function calls assert. It is assumed that the assert won't trigger, and even if it does, it can only trigger on the first call with a given set of parameters, and we don't care if the compiler moves the order of calls.

logs-show: export logic to add matches for units 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.

logs-show: add show_journal_by_user_unit Print the journal for a user session unit. For now this filters by _SYSTEMD_USER_UNIT and USER_UNIT and additionally _UID.

systemctl,loginctl,cgls: do not ellipsize cgroup members when --full is specified New file output.h with output flags and modes. --full parameter also for cgls and loginctl. Include 'all' parameter in flags (show_cgroup_by_path, show_cgroup, show_cgroup_and_extra, show_cgroup_and_extra_by_spec). get_process_cmdline with max_length == 0 will not ellipsize output. Replace LINE_MAX with 0 in some calls of get_process_cmdline. [zj: Default to --full when under pager for clgs. Drop '-f' since it wasn't documented and didn't actually work. Reindent a bit. ]

journal: implement message catalog 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.

journal: add ability to list unique fields to gatewayd

journal: support epxorting the journal in a format suitable for text/event-stream

logs-show: various cleanups Among other cleanups this introduces a threshold for the size of binary blobs we serialize as integer arrays in the JSON output. THis can be disabled via --all.

journalctl: rework JSON output mode 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.

journalctl: hightlight log lines by priority warn/notice = bright white < error = red

use #pragma once instead of foo*foo #define guards #pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers

journalctl: do not ellipsize when using pager If a pager is used, ellipsization is redundant — the pager does that better by hiding the part that cannot be shown. Pager's advantage is that the user can press → to view the hidden part of a message, and then ← to return.

logs: Adapt interface in log-show.c (show_journal_by_unit) Convert more flag arguments into one flag variable.

logs: Adapt interface in log-show.c (output_journal) In preparation for adding more output switches, convert a series of flags arguments into one flag variable.

journal: expose and make use of cutoff times of journal This helps explaining when the log output of "systemctl status" is incomplete because the logs got rotated since the service was started.

move more common files to shared/ and add them to shared.la
