2014-12-18journal: optimize iteration by skipping exhausted filesMichal Schmidt
If from a previous iteration we know we are at the end of a journal file, don't bother looking into the file again. This is complicated by the fact that the EOF does not have to be permanent (think of "journalctl -f"). So we also check if the number of entries in the journal file changed. This optimization has a similar effect as "journal: optimize iteration: skip whole files behind current location" had.
2014-12-18journal: drop unnecessary parameters of next_beyond_location()Michal Schmidt
offset is redundant, because the caller can rely on f->current_offset. The object pointer the function saves in *ret is thrown away by the caller.
2014-12-18journal: remove redundant variable new_offsetMichal Schmidt
The file's current_offset is already updated at this point, so let's use it.
2014-12-18journal: compare candidate entries using JournalFiles' locationsMichal Schmidt
When comparing the locations of candidate entries, we can rely on the location information stored in struct JournalFile.
2014-12-18journal: simplify set_location()Michal Schmidt
set_location() is called from real_journal_next() when a winning entry has been picked from among the candidates in journal files. The location type is always set to LOCATION_DISCRETE. No need to pass it as a parameter. The per-JournalFile location information is already updated at this point. No need for having the direction and offset here.
2014-12-18journal: keep per-JournalFile location info during iterationMichal Schmidt
In next_beyond_location() when we find a candidate entry in a journal file, save its location information in struct JournalFile. The purpose of remembering the locations of candidate entries is to be able to save work in the next iteration. This patch does only the remembering part. LOCATION_SEEK means the location identifies a candidate entry. When a winner is picked from among candidates, it becomes LOCATION_DISCRETE. LOCATION_TAIL here signifies we've iterated the file to the end (or the beginning in the case of reversed direction).

2014-12-18journal: move definition of LocationType to journal-file.hMichal Schmidt

2014-12-18core: use raw_clone instead of fork in signal handlerZbigniew Jędrzejewski-Szmek
fork() is not async-signal-safe and calling it from the signal handler could result in a deadlock when at_fork() handlers are called. Using the raw clone() syscall sidesteps that problem. The tricky part is that raise() does not work, since getpid() does not work. Add raw_getpid() to get the real pid, and use kill() instead of raise(). https://bugs.freedesktop.org/show_bug.cgi?id=86604

2014-12-17path: make the check for unsupported name_to_handle_at symmetricZbigniew Jędrzejewski-Szmek
If child supports, but the parent does not, or when the child does not support, but the parent does, assume the child is a mount point. Only if neither supports use the fallback.

2014-12-18util: in make_stdio() use dup2() rather than dup3()Lennart Poettering
dup3() allows setting O_CLOEXEC which we are not interested in. However, it also fails if called with the same fd as input and output, which is something we don't want. Hence use dup2(). Also, we need to explicitly turn off O_CLOEXEC for the fds, in case the input fd was O_CLOEXEC and < 3.

2014-12-16path: follow symbolic link for parent pathUmut Tezduyar Lindskog
[zj: When we lstat the target path, symlinks above the last component will be followed by both stat and lstat. So when we look at the parent, we should follow symlinks.]

The check for existing unit files and dropins is unified. path_join() is updated to not insert duplicate separators.
2014-12-16systemctl: share path lookup between 'cat' and 'edit'Zbigniew Jędrzejewski-Szmek
'systemctl cat' now works for templates too. 'systemctl edit' does not refuse to edit units that have changed on disk. That restriction didn't seem useful, actually editing units that have changed on disk before they are started is very reasonable. 'edit' with instances and templates works again: Now: $ build/systemctl edit getty@ Failed to copy /etc/systemd/system/getty@.service.d/override.conf to /etc/systemd/system/getty@.service.d/.override.confdff6290408c86369: Permission denied $ build/systemctl edit getty@tty3 Failed to create directories for /etc/systemd/system/getty@tty3.service.d/override.conf: Permission denied $ build/systemctl edit --full getty@tty3 Failed to copy /usr/lib/systemd/system/getty@.service to /etc/systemd/system/.getty@tty3.serviced3d175087e7e439b: Permission denied Failed to create temporary file for /etc/systemd/system/getty@tty3.service: Permission denied $ build/systemctl edit --full getty@ Failed to copy /usr/lib/systemd/system/getty@.service to /etc/systemd/system/.getty@.servicea3caad491c0f2f3d: Permission denied Failed to create temporary file for /etc/systemd/system/getty@.service: Permission denied

2014-12-15unit: handle nicely of certain unit types are not supported on specific systemsLennart Poettering
Containers do not really support .device, .automount or .swap units; Systems compiled without support for swap do not support .swap units; Systems without kdbus do not support .busname units. With this change attempts to start a unsupported unit types will result in an immediate "unsupported" job result, which is a lot more descriptive then before. Also, attempts to start device units in containers will now immediately fail instead of causing jobs to be enqueued that never go away.

2014-12-13systemctl: handle correctly template units for edit verbRonny Chevalier
Previously, if we provided getty@.service to systemctl edit it would have failed when using the bus because it is an invalid unit name. But it would have succeeded when searching in the filesystem. Now, we check if we have a template, if we do we search in the filesystem, if we don't have a templae and we can use the bus, we do. Furthermore, if we provided getty@tty1.service it would not have worked when searching the filesystem, but it would have worked with the bus. So now, when using the filesystem we use the template name and not the unit name, and the same when logging errors. (Also did a refactoring to avoid a long function)

2014-12-13journal: replace contexts hashmap with a plain arrayMichal Schmidt
try_context() is such a hot path that the hashmap lookup is expensive. The number of contexts is small - it is the number of object types. Using a hashmap is overkill. A plain array will do. Before: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m9.445s user 0m9.228s sys 0m0.213s After: $ time ./journalctl --since=2014-06-01 --until=2014-07-01 > /dev/null real 0m5.438s user 0m5.266s sys 0m0.170s
