FastDFS V5.08发布！！！

happy_fish100

历经4个月的时间，终于推出了V3.00 beta版本。
V3.00重大改进是支持将多个小文件合并存储到一个大文件中。
另外，多个tracker server采用Leader机制，支持Leader选举。
小文件合并存储，缺省配置是关闭的。如果需要使用这个特性，需要将tracker.conf中的use_trunk_file设置为true。


详细的ChangeLog如下：
Version 3.00  2011-06-19
* mass small files optimization
* add fixed block memory pool: common/fast_mblock.c
* bug fixed: tracker_mem.c do NOT clear g_groups fields
* bug fixed: slave file and appender file download ok
* bug fixed: tracker / storage run by group / user, set file owner
* tracker server support leader
* client support static library
* client_func.h add functions fdfs_tracker_group_equals and
   fdfs_get_file_ext_name
* bug fixed: test/dfs_func_pc.c compile ok
* storage server check free space enough when upload a file
