Lennart Poettering ccc403587c coredumpctl: initialize global vars 2012-10-26 20:23:28 +02:00
Lennart Poettering 85210bffd8 journal: provide an API that allows client to figure out whether they need to recheck the journal manually for changes in regular intervals 
Network file systems generally do not offer inotify() that would work
across the network. We hence cannot rely on inotify() exclusiely in
those case. Provide an API to determine these cases, and suggest doing
manual regular rechecks.

Note that this is not complete yet, as we need to rescan journal dirs on
network file systems explicitly to find new/removed files

Lennart Poettering a4bcff5ba3 journal: introduce entry array chain cache 
When traversing entry array chains for a bisection or for retrieving an
item by index we previously always started at the beginning of the
chain. Since we tend to look at the same chains repeatedly, let's cache
where we have been the last time, and maybe we can skip ahead with this
the next time.

This turns most bisections and index lookups from O(log(n)*log(n)) into
O(log(n)). More importantly however, we seek around on disk much less,
which is good to reduce buffer cache and seek times on rotational disks.

Zbigniew Jędrzejewski-Szmek 5de0409e54 journal: add tool to extract coredumps 
'systemd-coredumpctl' will list available coredumps:

 32666  500  500  11 /usr/lib64/valgrind/memcheck-amd64-linux

'systemd-coredumpctl dump PID' will write the coredump
to specified file or stdout.

Lennart Poettering 15119c1602 journalctl: implement quering field values with new -F switch

Lennart Poettering 3c1668da62 journal: add ability to list values a specified field can take in all entries of the journal 
The new 'unique' API allows listing all unique field values that a field
specified by a field name can take in all entries of the journal. This
allows answering queries such as "What units logged to the journal?",
"What hosts have logged into the journal?", "Which boot IDs have logged
into the journal?".

Ultimately this allows implementation of tools similar to lastlog based
on journal data.

Note that listing these field values will not work for journal files
created with older journald, as the field values are not indexed in
older files.

Lennart Poettering c3f60ec54d journalctl: add --unit=/-u to match by unit name 
This applies unit_name_mangle() to the specified unit names and hence
can handle weird characters nicely and will add unit suffixes as
necessary.

Lennart Poettering 9048b11f8b journalctl: harmonise in-stream comments

Incidentally, this also fixes a typo of MESSSAGE is three places.
