happy_fish100

2.06主要修復(fù)了幾個bug，包括一個改進(jìn)：
   同步效率提升：當(dāng)要同步的文件在目標(biāo)storage server上已存在，且文件大小相同時，不會往目標(biāo)服務(wù)器上同步。

詳細(xì)的ChangeLog如下：
Version 2.06  2010-12-26
* sync file op: do not sync the file which exists on dest storage server
   and the file size are same
* bug fixed: sync copy file will clear the existed file on dest storage
   server (truncate the file size to 0), this bug caused by V2.04
* bug fixed: make temp file discard system function mkstemp,
   use file sequence No. with pthread_mutex_lock
* bug fixed: function fastdfs_tracker_list_groups, when parameter group_name
   is null or empty string, return all groups info
* bug fixed: upload a file extends 2GB will fail
* bug fixed: tracker to tracker sync system data files, in function:
   tracker_mem_get_tracker_server, pTrackerStatus not be set properly

2.07主要改進(jìn)：
  對文件ID中文件大小這個字段進(jìn)行了增強，當(dāng)文件大小小于2GB時，高32位補隨機數(shù)，此時最高位設(shè)置為1
  php擴展新增刪除storage server的函數(shù)：fastdfs_tracker_delete_storage
  client目錄下增加了一個小工具：fdfs_file_info，用來獲取文件信息，如文件大小，創(chuàng)建時間等等

Version 2.07  2011-01-09
* slave file's prefix name can be empty
* FDFS_MAX_GROUPS change from 64 to 512

* tracker_service.c: in function list_group_storages, use strcpy
   intead of memcpy
* php extension add function fastdfs_tracker_delete_storage
* client add tool: fdfs_file_info to get file info, including file size,
   create timestamp, source storage ip address and crc32 signature

出現(xiàn)這樣的提示，應(yīng)該是找不到相應(yīng)的目錄和壓縮文件吧。
仔細(xì)查找一下原因，好吧。
