2013-08-22Optimize startswith() to macroKay Sievers
I guess it's easier and cleaner anyway to use simple static inline functions instead of defines.
2013-08-04systemd-delta: Only print colors when on a ttyDaniel Schaal
This make systemd-delta follow the behaviour of systemctl and journalctl. https://bugs.freedesktop.org/show_bug.cgi?id=67656 [zj: unify color query methods between those three programs.]
2013-07-18util: add split_pair() for splitting foo=bar stringsLennart Poettering
2013-07-16journal: add logging of effective capabilities _CAP_EFFECTIVEShawn Landden
I think this is the most important of the capabilities bitmasks to log.
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.
2013-06-09Allow for the use of @ in remote host callsDaniel Wallace
Without this you have to use %40 with the -H flag because dbus doesn't like the @ sign being unescaped.
2013-05-07hostname: only suppress setting of pretty hostname if it is non-equal to the ↵Lennart Poettering
static hostname and if the static hostname is set, too https://bugzilla.redhat.com/show_bug.cgi?id=957814
2013-05-06systemd-sleep: add support for freeze and standbyZbigniew Jędrzejewski-Szmek
A new config file /etc/systemd/sleep.conf is added. It is parsed by systemd-sleep and logind. The strings written to /sys/power/disk and /sys/power/state can be configured. This allows people to use different modes of suspend on systems with broken or special hardware. Configuration is shared between systemd-sleep and logind to enable logind to answer the question "can the system be put to sleep" as correctly as possible without actually invoking the action. If the user configured systemd-sleep to only use 'freeze', but current kernel does not support it, logind will properly report that the system cannot be put to sleep. https://bugs.freedesktop.org/show_bug.cgi?id=57793 https://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=7e73c5ae6e7991a6c01f6d096ff8afaef4458c36 http://lists.freedesktop.org/archives/systemd-devel/2013-February/009238.html SYSTEM_CONFIG_FILE and USER_CONFIG_FILE defines were removed since they were used in only a few places and with the addition of /etc/systemd/sleep.conf it becomes easier to just append the name of each file to the dir name.
2013-05-02Add __attribute__((const, pure, format)) in various placesZbigniew Jędrzejewski-Szmek
I'm assuming that it's fine if a _const_ or _pure_ function calls assert. It is assumed that the assert won't trigger, and even if it does, it can only trigger on the first call with a given set of parameters, and we don't care if the compiler moves the order of calls.
2013-05-01Annotate some functions as _const_Cristian Rodríguez
hexchar,unhexchar,octchar,unoctchar,decchar,undecchar are all const functions.
2013-04-30util: Add _sentinel_ to strextend()Colin Walters
Since it must be NULL terminated.
2013-04-30id128: when taking user input for a 128bit ID, validate syntaxLennart Poettering
Also, always accept both our simple hexdump syntax and UUID syntax.
2013-04-25Use attribute(unused) in PROTECT_ERRNOZbigniew Jędrzejewski-Szmek
clang emits warnings about unused attribute _saved_errno_, which drown out other—potentially useful—warnings. gcc documentation is not exactly verbose about the effects of __attribute__((unused)) on variables, but let's assume that it works if the unit test passes.
2013-04-25Add some extra __attribute__ ((format)) sCristian Rodríguez
2013-04-25Make up for attribute malloc with alloc_sizeZbigniew Jędrzejewski-Szmek
It is imperative that open source code be well attributed. Sprinkle attribute((alloc_size)) here and there, telling gcc how much memory we are actually allocating.
2013-04-25Remove erroneous attribute((malloc)) annotationsZbigniew Jędrzejewski-Szmek
According to gcc documentation, returned pointer "cannot alias any other pointer valid when the function returns" and "the memory has undefined content". This second part is (hopefully) untrue for all those functions.
2013-04-25util: rework safe_atod() to be locale-independentLennart Poettering
This adds some syntactic sugar with a macro RUN_WITH_LOCALE() that reset the thread-specific locale temporarily.
2013-04-19core/killall: use procfs_file_allocaZbigniew Jędrzejewski-Szmek
2013-04-16path-util: unify code for detecting OS treesLennart Poettering
This also makes sure we always detect an OS tree the same way, by checking for /etc/os-release.
2013-04-16macro: rework how we define cleanup macrosLennart Poettering
There's now a generic _cleanup_ macro with an argument. The macros for specific types are now defined using this macro, and in the header files where they belong. All cleanup handlers are now inline functions.
2013-04-16util: replace decimal_str_max() by a typesafe macro DECIMAL_STR_WIDTH()Lennart Poettering
DECIMAL_STR_WIDTH() now works on any numeric type, and is easier to distingish from DECIMAL_STR_MAX(). This also replaces another manual implementaiton of ulog10 by this macro.
2013-04-14util: introduce alloca0() and use it at a number of placesLennart Poettering
2013-04-13fileio: in envfiles, do not skip lines following empty linesZbigniew Jędrzejewski-Szmek

2013-04-12util: add wrapper for realloc to avoid specyfing typeZbigniew Jędrzejewski-Szmek
2013-04-10systemctl: ellipsize job list only when necessary, highlight runningZbigniew Jędrzejewski-Szmek
I was debugging systemd waiting on a missing disk, and noticed that the job listing could use some polishing. Jobs that are actually running are highlighted, so it's easier to see what very actually waiting for. Also, the needed widths are precalculated, to use available columns more ecomically.
2013-04-08machine-id: fix missing initializationsystemd/v201Lennart Poettering
2013-04-05Add _cleanup_globfree_Zbigniew Jędrzejewski-Szmek
Fixes a memleak in error path in exec_context_load_environment.
2013-04-05PAM, uaccess: check for logind, not for systemdMartin Pitt
It is possible to build systemd without logind or run logind without systemd init. Commit 66e41181 fixed sd_booted() to only succeed for systemd init; with that, testing for systemd init is wrong in the parts that talk to logind. In particular, this affects the PAM module and the "uaccess" udev builtin. Change sd_booted() to a new logind_running() which tests for /run/systemd/seats/. For details, see: <https://mail.gnome.org/archives/desktop-devel-list/2013-March/msg00092.html> https://bugs.freedesktop.org/show_bug.cgi?id=62754

2013-03-31bus: parse matches locally and allow registration of callbacks for themLennart Poettering
This includes code to parse and split up match strings which will also be useful to calculate bloom filter masks when the time comes.
2013-03-30bus: implement server mode, and anonymous authenticationLennart Poettering
2013-03-29Always use errno > 0 to help gccZbigniew Jędrzejewski-Szmek
gcc thinks that errno might be negative, and functions could return something positive on error (-errno). Should not matter in practice, but makes an -O4 build much quieter.
2013-03-28catalog: open up catalog internalsZbigniew Jędrzejewski-Szmek
In order to write tests for the catalog functions, they are made non-static and start taking a 'database' parameter, which is the name of a file with the preprocessed catalog entries. This makes it possible to make test-catalog part of the normal test suite, since it now only operates on files in /tmp. Some more tests are added.
2013-03-26Simplify the meaning of %sZbigniew Jędrzejewski-Szmek
The rules governing %s where just too complicated. First of all, looking at $SHELL is dangerous. For systemd --system, it usually wouldn't be set. But it could be set if the admin first started a debug shell, let's say /sbin/sash, and then launched systemd from it. This shouldn't influence how daemons are started later on, so is better ignored. Similar reasoning holds for session mode. Some shells set $SHELL, while other set it only when it wasn't set previously (e.g. zsh). This results in fragility that is better avoided by ignoring $SHELL totally. With $SHELL out of the way, simplify things by saying that %s==/bin/sh for root, and the configured shell otherwise. get_shell() is the only caller, so it can be inlined. Fixes one issue seen with 'make check'.
2013-03-22journalctl: give a nice hint about group membership based on ACLs of ↵Lennart Poettering
/var/log/journal If we notice that we unprivileged and not in any of the groups which have access to /var/log/journal, print a nice message about which groups do. This checks and prints all groups that are in the default ACL for /var/log/journal, which is not necessarily correct for all journal files, but pretty close.

2013-03-20util: add hexmem() and strextend() callsLennart Poettering
2013-03-20Make PrivateTmp dirs also inaccessible from the outsideZbigniew Jędrzejewski-Szmek
Currently, PrivateTmp=yes means that the service cannot see the /tmp shared by rest of the system and is isolated from other services using PrivateTmp, but users can access and modify /tmp as seen by the service. Move the private /tmp and /var/tmp directories into a 0077-mode directory. This way unpriviledged users on the system cannot see (or modify) /tmp as seen by the service.
2013-03-18journal,shared: add _cleanup_journal_close_Zbigniew Jędrzejewski-Szmek
2013-03-15core: reuse the same /tmp, /var/tmp and inaccessible dirMichal Sekletar
All Execs within the service, will get mounted the same /tmp and /var/tmp directories, if service is configured with PrivateTmp=yes. Temporary directories are cleaned up by service itself in addition to systemd-tmpfiles. Directory which is mounted as inaccessible is created at runtime in /run/systemd.
2013-03-13util, manager: and mempset() and use itMichal Schmidt
Just like mempcpy() is almost identical to memcpy() except the useful return value, so is the relation of mempset() to memset().
2013-03-08shared: inline trivial auto-cleanup functionsMichal Schmidt
2013-03-02job: print the "OK" status messages in normal greenMichal Schmidt
The "OK" status messages should not draw attention to themselves. It's better if they're not printed in bright/bold. Leave that to errors and warnings. Use a plain inconspicuous enterprisey green.
2013-02-28core/manager: print status messages about running jobsMichal Schmidt
Sometimes the boot gets stuck until a timeout hits. The usual timeouts are on the order of minutes, so users may lose patience. Print animated status messages telling the names of units with running jobs to make it easy to see what systemd is waiting for. The animation looks cooler with a shorter interval, but 1 s is OK and should not be too hard on slow serial console users.
2013-02-28util: split resolving of /dev/console into a new functionMichal Schmidt
2013-02-28util, core: add support for ephemeral status linesMichal Schmidt
Ephemeral status lines do not end with a newline and they expect to be overwritten by the next printed status line.
