History

orbiter ce1adf9955 serialized all logging using concurrency: high-performance search query situations as seen in yacy-metager integration showed deadlock situation caused by synchronization effects inside of sun.java code. It appears that the logger is not completely safe against deadlock situations in concurrent calls of the logger. One possible solution would be a outside-synchronization with 'synchronized' statements, but that would further apply blocking on all high-efficient methods that call the logger. It is much better to do a non-blocking hand-over of logging lines and work off log entries with a concurrent log writer. This also disconnects IO operations from logging, which can also cause IO operation when a log is written to a file. This commit not only moves the logger from kelondro to yacy.logging, it also inserts the concurrency methods to realize non-blocking logging. git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@6078 6c8d7289-2bf4-0310-a012-ef5d649a1542		16 years ago
