orbiter dc0c06e43d PLEASE MAKE A BACK-UP OF YOUR COMPLETE DATA DIRECTORY BEFORE USING THIS ... redesign for better IO performance enhanced database seek-time by avoiding write operations at distant positions of a database file. until now, a USEDC counter was written at the head-section of a kelondroRecords database file (which is the basic data structure of all kelondro database files) to store the actual number of records that are contained in the database. Now, this value is computed from the database file size. This is either done only once at start-time, or continuously when run in asserts enabled. The counter is then updated only in RAM, and written at close of the file. If the close fails, the correct number can be computed from the file size, and if this is not equal to the stored number it is a strong evidence that YaCY was not shut down properly. To preserve consistency, the complete storage-routine had to be re-written. Another change enhances read of nodes in some cases, where the data-tail can be read together with the data-head. This saves another IO lookup during each DB node fetch. Includes also many small bugfixes. IF ANYTHING GOES WRONG, ALL YOUR DATA IS LOST: PLEASE MAKE A BACK-UP git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@3375 6c8d7289-2bf4-0310-a012-ef5d649a1542		2007-02-20 08:35:51 +00:00
