2013-09-17specifier: rework specifier calls to return proper error messageLennart Poettering
Previously the specifier calls could only indicate OOM by returning NULL. With this change they will return negative errno-style error codes like everything else.

Only ASCII letters and digits are allowed.
2013-09-16Assume that /proc/meminfo can be missingZbigniew Jędrzejewski-Szmek
Travis tests are failing, probably because /proc/meminfo is not available in the test environment. The same might be true in some virtualized systems, so just treat missing /proc/meminfo as a sign that hibernation is not possible.
2013-09-13Advertise hibernation only if there's enough free swapZbigniew Jędrzejewski-Szmek
Condition that is checked is taken from upower: active(anon) < free swap * 0.98 This is really stupid, because the kernel knows the situation better, e.g. there could be two swap files, and then hibernation would be impossible despite passing this check, or the kernel could start supporting compressed swap and/or compressed hibernation images, and then this this check would be too stringent. Nevertheless, until we have something better, this should at least return a true negative if there's no swap. Logging of capabilities in the journal is changed to not strip leading zeros. I consider this more readable anyway. http://cgit.freedesktop.org/upower/tree/src/up-daemon.c#n613 https://bugzilla.redhat.com/show_bug.cgi?id=1007059

Fixup for ac4c8d6da8b5e.
2013-09-11Allow tabs in environment filesZbigniew Jędrzejewski-Szmek
bash allows them, and so should we. string_has_cc is changed to allow tabs, and if they are not wanted, they must be now checked for explicitly. There are two other callers, apart from the env file loaders, and one already checked anyway, and the other is changed to check. https://bugs.freedesktop.org/show_bug.cgi?id=68592 https://bugs.gentoo.org/show_bug.cgi?id=481554

2013-08-28Disallow invalid UTF-8 configurationZbigniew Jędrzejewski-Szmek
It is best to catch such errors early. If invalid UTF-8 ends up being given to dbus methods, the program will crash: process 20801: arguments to dbus_message_iter_append_basic() were incorrect, assertion "_dbus_check_is_valid_utf8 (*string_p)" failed in file dbus-message.c line 2598.

falconindy> the ellipsizing seems a bit wrong here.... I got a bit carried away with putting dots everywhere :)
2013-08-20logs-show: show source timestamp in verbose modeZbigniew Jędrzejewski-Szmek
This makes verbose behave like short mode, i.e. try to show the source timestamp, and fall back to journald timestamp only if unavailable or unparsable. I think verbose should be like short, only showing more fields, and showing different timestamps would be confusing.
2013-08-20logs-show: add short-precise mode with us timestampsZbigniew Jędrzejewski-Szmek
Also, always show us timestamps in verbose mode. https://bugzilla.redhat.com/show_bug.cgi?id=991678

2013-08-16build-sys: Add configure check for linux/btrfs.hMichael Marineau
btrfs.h was added to uapi in Linux 3.9. To fix building with older header versions this adds a configure check for the header and re-adds btrfs definitions to missing.h which was removed in bed2e820 along with two other ioctls used by gpt-auto-generator. [ Apparently, btrfs.h was only added recently: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=55e301fd57a6239ec14b91a1cf2e70b3dd135194 let's re-add it for now -- kay ]

2013-08-11logs-show: limit to 3 lines and use dots if not showing full messageZbigniew Jędrzejewski-Szmek
So far, we would show up to 128 bytes from a message, simply cutting of the rest. With multiline messages, it is quite common for a message to be longer than that, and this model doesn't really work anymore. A new limit is added: up to 3 lines will be shown, unless --full is used (c.f. first line below). The limit for bytes is extended to 300 bytes. An ellipsis will always be used, if some form of truncation occurs. If the tail of the message is cut off, either because of length or line limit, dots will be shown at the end of the last line. If this last line is short, the dots will be simply appended. If the last line is too long for that, it will be ellipsized with dots at the very end. Note that the limits are in bytes, not characters, and we suck at outputting unicode strings (c.f. last three lines below). Aug 11 10:46:21 fedora python[67]: test message line line...

2013-07-26rework systemd's own process environment handling/passingKay Sievers
Stop importing non-sensical kernel-exported variables. All parameters in the kernel command line are exported to the initial environment of PID1, but suppressed if they are recognized by kernel built-in code. The EFI booted kernel will add further kernel-internal things which do not belong into userspace. The passed original environ data of the process is not touched and preserved across re-execution, to allow external reading of /proc/self/environ for process properties like container*=.
2013-07-26journalctl: use _COMM= match for scriptsZbigniew Jędrzejewski-Szmek
In case of scripts, _EXE is set to the interpreter name, and _COMM is set based on the file name. Add a match for _COMM, and _EXE if the interpreter is not a link (e.g. for yum, the interpreter is /usr/bin/python, but it is a link to /usr/bin/python2, which in turn is a link to /usr/bin/python2.7, at least on Fedora, so we end up with _EXE=/usr/bin/python2.7). I don't think that such link chasing makes sense, because the final _EXE name is more likely to change.
2013-07-26shared: split mkdir_*() and mkdir_*_label() from each otherKay Sievers
Avoid pulling-in selinux for tools which just create directories but not need to fix the selinux label.
2013-07-24core: synchronously block when loggingLennart Poettering
Previously, the logging sockets were asynchronous and if clogged we'd lose messages. We did this to be extra careful given that PID 1 might need to spawn the logging daemon as response to PID 1's own log messages and we really should avoid a deadlock in that case. As it turns out this causes loss of too many messages, hence make the socket blocking again, however put a time limit on it to avoid unbounded deadlocks in the unlikely case they happen. https://bugs.freedesktop.org/show_bug.cgi?id=66664

If we pass a variable to open()'s flags parameter it really wants a mode parameter too, otherwise some gcc version whine. Hence, pass 0 in that case.

2013-07-16util.c:is_locale_utf8(): check, if "C" was set on purposeHarald Hoyer
If you have a ASCII only terminal, there is no way to set the charmap to ANSI_X3.4-1968, other than using LC_CTYPE=C. We don't want to assume a UTF-8 capable terminal in this case and only do so, if LANG, LC_ALL and LC_CTYPE are unset.
2013-07-16test-tables: allow sparse tables and check mapping for -1Zbigniew Jędrzejewski-Szmek
Jan: test-tables fails on my system. The one it's failing on is: syscall: 222 → (null) → -1 ... and indeed, our own tables should not have holes, but syscall tables certainly might.

2013-07-14systemd: fix NULL dereference when disabling a nonexistent instanceZbigniew Jędrzejewski-Szmek
Assertion 'p' failed at src/shared/path-util.c:51, function path_get_file_name(). Aborting. The unit file could not be found, and i->path would not be set. In 02b9e969 a code path was added which attempts to remove symlinks to a nonexistent (removed) unit file. This worked OK in case of non-instance services, but broke in the case of instance services. Behaviour wrt. to instance units is changed in the way that 02b9e969 changed it for non-instance units: it is now possible to remove instance symlinks to a template unit that has been removed. This patch isn't a full fix, because the behaviour wrt. to enabling and disabling instance units is still broken: e.g it is possible to start autovt@tty5.service, but it is not possible to enable it, because autovt@.service is a symlink, and on the other hand, disabling getty@tty5.service removes all symlinks to getty@.service, which is wrong too. But segfaults make bad pr, so let's add at least this partial fix for now.

Before, "systemctl reenable getty@tty1.service" would fail with: Failed to issue method call: File exists To fix this, reimplement "reenable" explicitly as a disable followed by an enable. This is shorter and is how the man page documents its behavior.

2013-07-11cgroup: simplify how instantiated units are mapped to cgroupsLennart Poettering
Previously for an instantiated unit foo@bar.service we created a cgroup foo@.service/foo@bar.service, in order to place all instances of the same template inside the same subtree. As we now implicitly add all instantiated units into one per-template slice we don't need this complexity anymore, and instance units can map directly to the cgroups of their full name.
