我目前正在使用带有 Berkeley DB 的 svn，今天当我尝试访问存储库时收到错误“无法打开请求的 SVN 文件系统”。
当我运行“svnadmin recovery”时，我得到以下信息：
svnadmin: DB_RUNRECOVERY: Fatal error, run database recovery
svnadmin: bdb: DB_LOGC->get: LSN 564/955694: invalid log record header
svnadmin: bdb: Skipping log file e:\svn\db\log.0000000368: historic log

svnadmin: bdb: DB_LOGC->get: log record LSN 564/955710: checksum mismatch
svnadmin: bdb: DB_LOGC->get: catastrophic recovery may be required
svnadmin: bdb: PANIC: DB_RUNRECOVERY: Fatal error, run database recovery
svnadmin: bdb: PANIC: DB_RUNRECOVERY: Fatal error, run database recovery
我已经下载了 Berkley DB 二进制文件，并尝试运行 db_recover，但出现以下错误：
c:\Program Files\Sleepycat Software\Berkeley DB 4.4.20\bin>db_recover
-vech e:\svn\db
Finding last valid log LSN: file: 565 offset 131910

db_recover: PANIC: fatal region error detected; run recovery

db_recover: DB_ENV->open: DB_RUNRECOVERY: Fatal error, run database recovery
我的问题听起来与这里描述的问题类似：

因此，我从 db 目录中删除了 __db* 和 lot.* 文件，并尝试再次运行上述命令，但现在 db_recover 和 svnadmin recovery 给出以下内容：
c:\Program Files\Sleepycat Software\Berkeley DB 4.4.20\bin>db_recover
-vech e:\svn-repair\db
Finding last valid log LSN: file: 1 offset 28

是的，jibblish 字符确实出现了。
如果有人能帮助我恢复数据库，我将不胜感激。:(
