2013-07-16journal: return -ECHILD after a forkZbigniew Jędrzejewski-Szmek
A few asserts are replaced with 'return -EINVAL'. I think that assert should not be used to check argument in public functions. Fields in struct sd_journal are rearranged to make it less swiss-cheesy.
2013-07-16journalctl: Add support for showing messages from a previous bootJan Janssen
Hi, I redid the boot ID look up to use enumerate_unique. This is quite fast if the cache is warm but painfully slow if it isn't. It has a slight chance of returning the wrong order if realtime clock jumps around. This one has to do n searches for every boot ID there is plus a sort, so it depends heavily on cache hotness. This is in contrast to the other way of look-up through filtering by a MESSAGE_ID, which only needs about 1 seek + whatever amount of relative IDs you want to walk. I also have a linked-list + (in-place) mergesort version of this patch, which has pretty much the same runtime. But since this one is using libc sorting and armortized allocation, I prefer this one. To summarize: The MESSAGE_ID way is a *lot* faster but can be incomplete due to rotation, while the enumerate+sort will find every boot ID out there but will be painfully slow for large journals and cold caches. You choose :P Jan

2013-06-24journald: always vacuum empty offline filesZbigniew Jędrzejewski-Szmek
Corrupted empty files are relatively common. I think they are created when a coredump for a user who never logged anything before is attempted to be written, but the write does not succeed because the coredump is too big, but there are probably other ways to create those, especially if the machine crashes at the right time. Non-corrupted empty files can also happen, e.g. if a journal file is opened, but nothing is ever successfully written to it and it is rotated because of MaxFileSec=. Either way, each "empty" journal file costs around 3 MB, and there's little point in keeping them around.
2013-06-24journald: fix space limits reportingZbigniew Jędrzejewski-Szmek
Reporting of the free space was bogus, since the remaining space was compared with the maximum allowed, instead of the current use being compared with the maximum allowed. Simplify and fix by reporting limits directly at the point where they are calculated. Also, assign a UUID to the message.

2013-06-22journal-verify: allow unlinked data entriesZbigniew Jędrzejewski-Szmek
Sometimes an entry is not successfully written, and we end up with data items which are "unlinked", not connected to, and not used by any entry. This will usually happen when we write to write a core dump, and the initial small data fields are written successfully, but the huge COREDUMP= field is not written. This situation is hard to avoid, but the results are mostly harmless. Thus only warn about unused data items. Also, be more verbose about why journal files failed verification. This should help diagnose journal failure modes without resorting to a hexadecimal editor. https://bugs.freedesktop.org/show_bug.cgi?id=65235 (esp. see system.journal attached to the bug report).
2013-06-21journald: bump the journal per-unit ratelimit defaultsLennart Poettering
Too many people kept hitting them, so let's increase the limits a bit. https://bugzilla.redhat.com/show_bug.cgi?id=965803
2013-06-20journal: allow callers to specify OBJECT_PID=Zbigniew Jędrzejewski-Szmek
When journald encounters a message with OBJECT_PID= set coming from a priviledged process (UID==0), additional fields will be added to the message: OBJECT_UID=, OBJECT_GID=, OBJECT_COMM=, OBJECT_EXE=, OBJECT_CMDLINE=, OBJECT_AUDIT_SESSION=, OBJECT_AUDIT_LOGINUID=, OBJECT_SYSTEMD_CGROUP=, OBJECT_SYSTEMD_SESSION=, OBJECT_SYSTEMD_OWNER_UID=, OBJECT_SYSTEMD_UNIT= or OBJECT_SYSTEMD_USER_UNIT=. This is for other logging daemons, like setroubleshoot, to be able to augment their logs with data about the process. https://bugzilla.redhat.com/show_bug.cgi?id=951627

2013-06-13journald: do not calculate free space too earlyZbigniew Jędrzejewski-Szmek
Since the system journal wasn't open yet, available_space() returned 0. Before: systemd-journal[22170]: Allowing system journal files to grow to 4.0G. systemd-journal[22170]: Journal size currently limited to 0B due to SystemKeepFree. After: systemd-journal[22178]: Allowing system journal files to grow to 4.0G. systemd-journal[22178]: Journal size currently limited to 3.0G due to SystemKeepFree. Also, when failing to write a message, show how much space was needed: "Failed to write entry (26 items, 260123456 bytes) despite vacuuming, ignoring: ...".

2013-06-10journal: letting (interleaved) seqnums goZbigniew Jędrzejewski-Szmek
In the following scenario: server creates system.journal server creates user-1000.journal both journals share the same seqnum_id. Then server writes to user-1000.journal first, and server writes to system.journal a bit later, and everything is fine. The server then terminates (crash, reboot, rsyslog testing, whatever), and user-1000.journal has entries which end with a lower seqnum than system.journal. Now server is restarted server opens user-1000.journal and writes entries to it... BAM! duplicate seqnums for the same seqnum_id. Now, we usually don't see that happen, because system.journal is closed last, and opened first. Since usually at least one message is written during boot and lands in the system.journal, the seqnum is initialized from it, and is set to a number higher than than anything found in user journals. Nevertheless, if system.journal is corrupted and is rotated, it can happen that an entry is written to the user journal with a seqnum that is a duplicate with an entry found in the corrupted system.journal~. When browsing the journal, journalctl can fall into a loop where it tries to follow the seqnums, and tries to go the next location by seqnum, and is transported back in time to to the older duplicate seqnum. There is not way to find out the maximum seqnum used in a multiple files, without actually looking at all of them. But we don't want to do that because it would be slow, and actually it isn't really possible, because a file might e.g. be temporarily unaccessible. Fix the problem by using different seqnum series for user journals. Using the same seqnum series for rotated journals is still fine, because we know that nothing will write to the rotated journal anymore.

2013-06-10journal: change direction tests to use the same convention (cp </> np)Zbigniew Jędrzejewski-Szmek
The order was different in various places, which makes it harder to read to code. Also consistently use ternany for all direction checks. Remove one free(NULL).
2013-06-10journal: remember last direction of search and keep offset cacheZbigniew Jędrzejewski-Szmek
The fields in JournalFile are moved around to avoid wasting 7 bytes because of alignment.
2013-06-10journalctl: allow the user to specify the file(s) to useZbigniew Jędrzejewski-Szmek
This is useful for debugging and feels pretty natural. For example answering the question "is this big .journal file worth keeping?" is made easier.
2013-06-10journal: add sd_journal_open_filesZbigniew Jędrzejewski-Szmek
This allows the caller to explicitly specify which journal files should be opened. The same functionality could be achieved before by creating a directory and playing around with symlinks. It is useful to debug stuff and explore the journal, and has been requested before. Waiting is supported, the journal will notice modifications on the files supplied when opening the journal, but will not add any new files.
2013-06-10tests: add test for empty journal filesZbigniew Jędrzejewski-Szmek
The headers are currently not printed properly: some "(null)"s appear.
2013-06-10journalctl: print monotonic timestamp in --headerZbigniew Jędrzejewski-Szmek
2013-06-10journalctl: print proper IDs with --headerZbigniew Jędrzejewski-Szmek
The same buffer was used for two different IDs, messing up the output.
2013-06-10Use stdint.h macros instead of casts to print uint64_t valuesZbigniew Jędrzejewski-Szmek
Casts are visually heavy, and can obscure unwanted truncations.
2013-06-10journalctl: no color for --reboot-- when not on ttyZbigniew Jędrzejewski-Szmek
2013-06-10journal: loop less in MATCH_AND_TERM conditionalsZbigniew Jędrzejewski-Szmek
AND term usually don't have many subterms (4 seems to be the maximum sensible number, e.g. _BOOT_ID && _SYSTEMD_UNIT && _PID && MESSAGE_ID). Nevertheless, the cost of checking each subterm can be relatively high, especially when the nested terms are compound, and it makes sense to minimize the number of checks. Instead of looping to the end and then again over the whole list once again after at least one term changed the offset, start the loop at the term which caused the change. This way ½ terms in the AND match are not checked unnecessarily again.
2013-06-10journalctl: add --system/--user flagsZbigniew Jędrzejewski-Szmek
--user basically gives messages from your own systemd --user services. --system basically gives messages from PID 1, kernel, and --system services. Those two options are not exahustive, because a priviledged user might be able to see messages from other users, and they will not be shown with either or both of those flags.
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
2013-06-04systemctl: limit logs in status to current bootZbigniew Jędrzejewski-Szmek
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)
2013-06-01journal: take KeepFree into account when reporting maximum sizeDaniel Albers
When reporting the maximum journal size add a hint if it's limited by KeepFree.
2013-05-30journald: DO recalculate the ACL mask, but only if it doesn't existJan Alexander Steffens (heftig)
Since 11ec7ce, journald isn't setting the ACLs properly anymore if the files had no ACLs to begin with: acl_set_fd fails with EINVAL. An ACL with ACL_USER or ACL_GROUP entries but no ACL_MASK entry is invalid, so make sure a mask exists before trying to set the ACL.
