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.
2015-01-05journald: process SIGBUS for the memory maps we set upLennart Poettering
Even though we use fallocate() it appears that file systems like btrfs will trigger SIGBUS on certain low-disk-space situation. We should handle that, hence catch the signal, add it to a list of invalidated pages, and replace the page with an empty memory area. After each write check if SIGBUS was triggered, and consider the write invalid if it was. This should make journald a lot more robust with file systems where fallocate() is not reliable, for example all CoW file systems (btrfs...), where changing written data can fail with disk full errors. https://bugzilla.redhat.com/show_bug.cgi?id=1045810
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().
2014-08-21notify: send STOPPING=1 from our daemonsLennart Poettering
2014-07-31Always prefer our headers to system headersZbigniew Jędrzejewski-Szmek
In practice this shouldn't make much difference, but sometimes our headers might be newer, and we want to test them.

2013-03-23journald: remove unconditional log_*() use in the main loopKay Sievers
Setting MaxRetentionSec= caused the kernel log to overflow and the journal daemon to enter an endless loop. Logging from the journald main loop gets directed to /dev/kmsg, which wakes up journald again. We skip the import of this message by checking for our own PID, but this still causes the main loop to never go to sleep again because we never stopped logging from there.
2012-11-14build-sys: store journald code in a noinst libraryZbigniew Jędrzejewski-Szmek
The point is to allow the use of journald functions by other binaries. Before, journald code was split into multiple files (journald-*.[ch]), but all those files all required functions from journald.c. And journald.c has its own main(). Now, it is possible to link against those functions, e.g. from test binaries. This constitutes a fix for https://bugzilla.redhat.com/show_bug.cgi?id=872638. The patch does the following: 1. rename journald.h to journald-server.h and move corresponding code to journald-server.c. 2. add journald-server.c and other journald-*.c parts to libsystemd-journal-internal. 3. remove journald-syslog.c from test_journal_syslog_SOURCES, since it is now contained in libsystemd-journal-internal. There are no code changes, apart from the removal of a few static's, to allow function calls between files.
2012-10-16journal: implement time-based rotation/vacuumingLennart Poettering
This also enables time-based rotation (but not vacuuming) after 1month, so that not more one month of journal is lost at a time per vacuuming.
2012-10-13log: introduce a macro to format message idZbigniew Jędrzejewski-Szmek
The MESSAGE_ID=... stanza will appear in countless number of places. It is just too long to write it out in full each time. Incidentally, this also fixes a typo of MESSSAGE is three places.

This adds forward-secure authentication of journal files. This patch includes key generation as well as tagging of journal files, Verification of journal files will be added in a later patch.

2012-07-26log.h: new log_oom() -> int -ENOMEM, use itShawn Landden
also a number of minor fixups and bug fixes: spelling, oom errors that didn't print errors, not properly forwarding error codes, few more consistency issues, et cetera
2012-07-25use "Out of memory." consistantly (or with "\n")Shawn Landden
glibc/glib both use "out of memory" consistantly so maybe we should consider that instead of this. Eliminates one string out of a number of binaries. Also fixes extra newline in udev/scsi_id
