2013-10-01hashmap: size hashmap bucket array dynamicallyLennart Poettering
Instead of fixing the hashmap bucket array to 127 entries dynamically size it, starting with a smaller one of 31. As soon as a fill level of 75% is reached, quadruple the size, and so on. This should siginficantly optimize the lookup time in large tables (from O(n) back to O(1)), and save memory on smaller tables (which most are).

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.

2013-02-11binfmt,tmpfiles,modules-load,sysctl: rework the various early-boot services ↵Lennart Poettering
that work on .d/ directories This unifies much of the logic behind them: - All four will now ofllow the rule that the earlier file and earlier assignment in the .d/ directories wins. Before, sysctl was the only outlier, where the later setting always won. - All four now support getopt() and --help on the command line. - All four can now handle specification of configuration file names on the command line to apply. The tools will automatically find them, and apply them. Previously only tmpfiles could do that. This is useful for %post scripts in RPMs and suchlike. - This fixes various error path issues in conf_files_list()
2012-10-26journal: introduce entry array chain cacheLennart Poettering
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.
2012-10-25journal: properly serialize fields with multiple values into JSONLennart Poettering
This now matches the JSON serialization spec from: http://www.freedesktop.org/wiki/Software/systemd/json
2012-10-18journal: add ability to list values a specified field can take in all ↵Lennart Poettering
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.
2012-08-14service: add options RestartPreventExitStatus and SuccessExitStatusLukas Nykryn
In some cases, like wrong configuration, restarting after error does not help, so administrator can specify statuses by RestartPreventExitStatus which will not cause restart of a service. Sometimes you have non-standart exit status, so this can be specified by SuccessfulExitStatus.
2012-07-19use #pragma once instead of foo*foo #define guardsShawn Landden
#pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers

2012-04-12relicense to LGPLv2.1 (with exceptions)Lennart Poettering
We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.
