* configure.ac: use LT_LIBM to check for the maths library * src/accelerometer/Makefile.am: use $(LIBM) instead of -lm in the link flags This causes all executables (except accelerometer) and libraries to be linked without libm, which they do not need.

2014-10-31hashmap: rewrite the implementationMichal Schmidt
We reintroduce hashmap.{h,c}, list.h and set.h verbatim from upstream, before we punt dead code. The following is the upstream message: This is a rewrite of the hashmap implementation. Its advantage is lower memory usage. It uses open addressing (entries are stored in an array, as opposed to linked lists). Hash collisions are resolved with linear probing and Robin Hood displacement policy. See the references in hashmap.c. Some fun empirical findings about hashmap usage in systemd on my laptop: - 98 % of allocated hashmaps are Sets. - Sets contain 78 % of all entries, plain Hashmaps 17 %, and OrderedHashmaps 5 %. - 60 % of allocated hashmaps contain only 1 entry. - 90 % of allocated hashmaps contain 5 or fewer entries. - 75 % of all entries are in hashmaps that use trivial_hash_ops. Clearly it makes sense to: - store entries in distinct entry types. Especially for Sets - their entries are the most numerous and they require the least information to store an entry. - have a way to store small numbers of entries directly in the hashmap structs, and only allocate the usual entry arrays when the direct storage is full. The implementation has an optional debugging feature (enabled by defining the ENABLE_HASHMAP_DEBUG macro), where it: - tracks all allocated hashmaps in a linked list so that one can easily find them in gdb, - tracks which function/line allocated a given hashmap, and - checks for invalid mixing of hashmap iteration and modification. Since entries are not allocated one-by-one anymore, mempools are not used for entries. Originally I meant to drop mempools entirely, but it's still worth it to use them for the hashmap structs. My testing indicates that it makes loading of units about 5 % faster (a test with 10000 units where more than 200000 hashmaps are allocated - pure malloc: 449±4 ms, mempools: 427±7 ms). Here are some memory usage numbers, taken on my laptop with a more or less normal Fedora setup after booting with SELinux disabled (SELinux increases systemd's memory usage significantly): systemd (PID 1) Original New Change dirty memory (from pmap -x 1) [KiB] 2152 1264 -41 % total heap allocations (from gdb-heap) [KiB] 1623 756 -53 % Signed-off-by: Anthony G.

2014-04-24udev: remove seqnum API and all assumptions about seqnumsKay Sievers
The way the kernel namespaces have been implemented breaks assumptions udev made regarding uevent sequence numbers. Creating devices in a namespace "steals" uevents and its sequence numbers from the host. It confuses the "udevadmin settle" logic, which might block until util a timeout is reached, even when no uevent is pending. Remove any assumptions about sequence numbers and deprecate libudev's API exposing these numbers; none of that can reliably be used anymore when namespaces are involved. Signed-off-by: Anthony G.

2013-07-31Revert "static-nodes: remove creation of static nodes if HAVE_LIBKMOD"Ian Stakenvicius
This reverts commit aa417a4d83999f6d7f092161d5c411b8cbce9977. Preface: The kmod+tmpfiles static dev-node creation requires two commands to be executed at runtime -- it is not something that will automatically occur without a system's setup being explicitly designed or changed so that these commands are executed. Preface2: In order for the kmod+tmpfiles static dev-node creation to work properly, that -must- be executed at startup before {systemd-,}udevd starts. The reason for this is because udevd will only set permissions on those files at startup, and so if udevd starts beforehand then these nodes will exist with permissions that are (probably) too restrictive. The function in udevd which creates static-nodes is non-fatal and only updates mtime on the devnodes if they already exist. As such, if a system is configured to execute kmod+tmpfiles to create static-nodes, because that must occur first, eudev's udevd will not conflict. Also, if a system does not execute kmod+tmpfiles, then eudev will still create the static devnodes, even if kmod-14 or higher is installed. There *may* be a conflict if kmod+tmpfiles is executed after udevd starts, but as per "preface2" this is not a supported configuration. Signed-off-by: Ian Stakenvicius <axs@gentoo.org>

There were some adjustments made in order to support the code differences between upstream and eudev, which was done by myself. Also of note is that the code can still be disabled via the --disable-keymaps configure option, which was removed from upstream. Signed-off-by: Ian Stakenvicius <axs@gentoo.org>
