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().
2014-11-28log: fix order of log_unit_struct() to match other logging callsLennart Poettering
Also, while we are at it, introduce some syntactic sugar for creating ERRNO= and MESSAGE= structured logging fields.
2014-11-27log: rearrange log function namingLennart Poettering
- Rename log_meta() → log_internal(), to follow naming scheme of most other log functions that are usually invoked through macros, but never directly. - Rename log_info_object() to log_object_info(), simply because the object should be before any other parameters, to follow OO-style programming style.

2014-11-27journalctl: print all possible lines immediately with --follow + --sinceAndrej Manduch
When I tryed to run journalctl with --follow and --since arguments it behaved very strangely. First It prints logs from what I specified in --since argument, then printed 10 lines (as is default in --follow) and when app put something new in to log journalctl printed everithing from the last printed line. How to reproduce: 1. run: journalctl -m --since 14:00 --follow Then you'll see 10 lines of logs since 14:00. After that wait until some app add something in the journal or just run `systemd-cat echo test` 2. After that journalctl will print every single line since 14:00 and will follow as expected. As long as --since and --follow will eventually print all relevant lines, I seen no reason why not to print them right away and not after first new message in journal.

2014-11-26journald: proceed even if some sockets are unknownZbigniew Jędrzejewski-Szmek
systemd-journald would refuse to start if it received an unknown socket from systemd. This is annoying, because the failure more for systemd-journald is unpleasant: systemd will keep restarting journald, but most likely the same error will occur every time. It is better to continue. journald will try to open missing sockets on its own, so things should mostly work. One question is whether to close the sockets which cannot be parsed or to keep them open. Either way we might lose some messages. This failure is most likely for the audit socket (selinux issues), which can be opened multiple times so this not a problem, so I decided to keep them open because it makes it easier to debug the issue after the system is fully started.

Also, make all parsing of the kernel cmdline non-fatal.
2014-11-07copy: change error code when hitting copy limit to EFBIGLennart Poettering
After all, this is about files, not arguments, hence EFBIG is more appropriate than E2BIG

Similar to auditd actually turn on auditing as we are starting. This way we can operate entirely without auditd around.

2014-10-30journal: when sending huge log messages prefer memfds over temporary files ↵Lennart Poettering
in /dev/shm Previously when a log message grew beyond the maximum AF_UNIX/SOCK_DGRAM datagram limit we'd send an fd to a deleted file in /dev/shm instead. Because the sender could still modify the file after delivery we had to immediately copy the data on the receiving side. With memfds we can optimize this logic, and also remove the dependency on /dev/shm: simply send a sealed memfd around, and if we detect the seal memory map the fd and use it directly.

2014-10-26journald: fix flushingZbigniew Jędrzejewski-Szmek
Commit 74055aa762 'journalctl: add new --flush command and make use of it in systemd-journal-flush.service' broke flushing because journald checks for the /run/systemd/journal/flushed file before opening the permanent journal. When the creation of this file was postponed, flushing stoppage ensued.

2014-10-23journal: make sd_journal::files a OrderedHashmapMichal Schmidt
Anything that uses hashmap_next() almost certainly cares about the order and needs to be an OrderedHashmap.
2014-10-23journal: make Server::user_journals an OrderedHashmapMichal Schmidt
Order matters here. It replaces oldest entries first when USER_JOURNALS_MAX is reached.
2014-10-23journal: make JournalFile::chain_cache an OrderedHashmapMichal Schmidt
The order of entries may matter here. Oldest entries are evicted first when the cache is full. (Though I don't see anything to rejuvenate entries on cache hits.)

2014-10-23journalctl: add new --flush command and make use of it in ↵Lennart Poettering
systemd-journal-flush.service This new command will ask the journal daemon to flush all log data stored in /run to /var, and wait for it to complete. This is useful, so that in case of Storage=persistent we can order systemd-tmpfiles-setup afterwards, to ensure any possibly newly created directory in /var/log gets proper access mode and owners.

string_is_safe() After all, we know have this as generic validator, so let's be correct and use it wherver applicable.
2014-10-22journal: do server_vacuum for sigusr1WaLyong Cho
runtime journal is migrated to system journal when only "/run/systemd/journal/flushed" exist. It's ok but according to this the system journal directory size(max use) can be over the config. If journal is not rotated during some time the journal directory can be remained as over the config(or default) size. To avoid, do server_vacuum just after the system journal migration from runtime.

2014-10-09sd-journal: fix sd_journal_enumerate_unique skipping valuesJan Janssen
sd_journal_enumerate_unique will lock its mmap window to prevent it from being released by calling mmap_cache_get with keep_always=true. This call may return windows that are wider, but compatible with the parameters provided to it. This can result in a mismatch where the window to be released cannot properly be selected, because we have more than one window matching the parameters of mmap_cache_release. Therefore, introduce a release_cookie to be used when releasing the window. https://bugs.freedesktop.org/show_bug.cgi?id=79380
2014-10-09sd-journal: change check to assertZbigniew Jędrzejewski-Szmek
As of 0f99f74a14 'sd-journal: verify that object start with the field name' this condition should never happen.
2014-10-09sd-journal: do not reset sd_j_enumerate_unique position on errorZbigniew Jędrzejewski-Szmek
systemctl would call sd_j_enumerate_unique() interleaved with sd_j_next(). But the latter can remove a file if it detects an error in it. In those circumstances sd_j_enumerate_unique would restart with the first file in hashmap. With many corrupted files sd_j_enumerate_unique might iterate over the list multiple times. Avoid this by jumping to the next file in unique list if possible, or setting a flag that tells sd_j_enumerate_unique that it is done otherwise.
2014-10-08time: functions named "internal" really shouldn't be exportedLennart Poettering

2014-10-03journalctl: make --utc work everywhereJan Synacek
The --utc option was introduced by commit 9fd290443f5f99fca0dcd4216b1de70f7d3b8db1. Howerver, the implementation was incomplete.
