Simon Wilkinson	4188865670	Update .gitignore files ... Update (and create) .gitignore files across the tree Change-Id: I7534e4f1eac44e6024f86591a171b63a64c6f320 Reviewed-on: http://gerrit.openafs.org/7241 Tested-by: BuildBot <buildbot@rampaginggeek.com> Reviewed-by: Derrick Brashear <shadow@dementix.org>	2012-04-18 20:26:54 -07:00
Simon Wilkinson	20448059f0	opr: Add Bob Jenkins's hash functions ... This imports a small subset of Bob Jenkins lookup3.c hash functions into the opr library. At present we only import the subset of this that deals with aligned arrays of integers, as this addresses our immediate need. It seems likely that if we're interested in a hash function for string arrays (or other arbitrary data), that more recent functions such like SpookyHash (from Bob Jenkins, again) or CityHash (from Google) may be a better solution. The immediate use case for this is removing the use of the '%' operator when indexing speed critical hash tables, as well as ensuring fairer distribution of entries across these tables. A short set of test cases is also provided Change-Id: I0ae26382e77da02204a30a95747f7d6de8c4f24a Reviewed-on: http://gerrit.openafs.org/6095 Reviewed-by: Jeffrey Altman <jaltman@secure-endpoints.com> Tested-by: Jeffrey Altman <jaltman@secure-endpoints.com>	2011-11-21 07:45:14 -08:00
Simon Wilkinson	5574ff814f	opr: Add a red/black tree implementation ... Add an implementation of red/black trees to our runtime library. This is originally derived from the FreeBSD macro-based rbtree implementation, but is heavily reworked to not use macros, to improve legibility, and to favour speed over structure compactness. A test suite is provided in tests/opr/ Change-Id: I123209d3f89b5f8c1b85d1e5cd7d1d650ccc68ed Reviewed-on: http://gerrit.openafs.org/5838 Tested-by: BuildBot <buildbot@rampaginggeek.com> Reviewed-by: Derrick Brashear <shadow@dementix.org>	2011-11-12 06:48:17 -08:00
