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.

2014-10-31keymap: Ignore brightness keys on Dell Inspiron 1520 to avoid double eventsHans de Goede
On the Dell Inspiron 1520 both the atkbd and acpi-video input devices report an event for pressing the brightness up / down key-combos, resulting in user space seeing double events and increasing / decreasing the brightness 2 steps for each keypress. This hwdb snippet suppresses the atkbd events, making the Inspiron 1520 work like most modern laptops which emit brightness up / down events through acpi-video only.

2014-10-25hashmap: introduce hashmap_reserve()Michal Schmidt
With the current hashmap implementation that uses chaining, placing a reservation can serve two purposes: - To optimize putting of entries if the number of entries to put is known. The reservation allocates buckets, so later resizing can be avoided. - To avoid having very long bucket chains after using hashmap_move(_one). In an alternative hashmap implementation it will serve an additional purpose: - To guarantee a subsequent hashmap_move(_one) will not fail with -ENOMEM (this never happens in the current implementation).

2014-10-25shared/log: add log_trace as compile-time optional debuggingZbigniew Jędrzejewski-Szmek
Repetetive messages can be annoying when running with SYSTEMD_LOG_LEVEL=debug, but they are sometimes very useful when debugging problems. Add log_trace which is like log_debug but becomes a noop unless LOG_TRACE is defined during compilation. This makes it easy to enable very verbose logging for a subset of programs when compiling from source. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

The compaq ku 0133 keyboard has 8 special keys at the top: http://lackof.org/taggart/hacking/keyboard/cpqwireless.jpg 3 of these use standard HID usage codes from the consumer page, the 5 others use part of the reserved 0x07 - 0x1f range. This commit adds mapping for this keyboard for these reserved codes, making the other 5 keys work.
