SVN Management

前段時間公司SA離職，主動申請了一部分工作是關於SVN維護的，新的SA來了，馬上要交接，小小總結一下這段時間的SVN Management Experience。

NOTE：如何創建SVN 版本庫就不贅述了， 不會Google。

以下是一些日創管理時遇到的issue 和 備份和鏡像的恢復。
repo_local_path: file:///e:/svn/7thOnline

I Dairy Schedule
    1 sync with main server manaully
        svnsync sync repo_local_path

    NOTE:
           Issue 3：locked
                    C:\Documents and Settings\ntadmin>svnsync sync repo_local_path
                        Failed to get lock on destination repos, currently held by 'Utility01:c8d0ab56-e
                    4f5-7244-a8a6-ba639e98254e'
                        Failed to get lock on destination repos, currently held by 'Utility01:c8d0ab56-e
                    4f5-7244-a8a6-ba639e98254e'
                        Failed to get lock on destination repos, currently held by 'Utility01:c8d0ab56-e

                        Failed to get lock on destination repos, currently held by 'Utility01:c8d0ab56-e
                    4f5-7244-a8a6-ba639e98254e'
                        Failed to get lock on destination repos, currently held by 'Utility01:c8d0ab56-e
                    4f5-7244-a8a6-ba639e98254e'
                        Failed to get lock on destination repos, currently held by 'Utility01:c8d0ab56-e

                        svnsync: Couldn't get lock on destination repos after 10 attempts

              Solution： unlock
                    svn propdel svn:sync-lock --revprop -r 0 repo_local_path

II: Recovery
    如果有幾個main svn server 的鏡像 一個鏡像無法同步了，我們可以通過物理拷貝 其他正常鏡像的相關文件 去恢復此鏡像。 如果只有一個鏡像，就不能通過這種方式恢復此鏡像。（不得已使用）
   copy_svn.bat: (至於某倉庫root path)
    mkdir dst
    copy db\current dst\

    mkdir dst\revprops
    copy db\revprops\0 dst\revprops
    copy db\revprops\46989 dst\revprops

    mkdir dst\revs
    copy db\revs\0 dst\revs
    copy db\revs\46989 dst\revs

    Dump / Load Steps:

     1 dump from the mian svn server or other mirror svn server  (Eg:from version A to version B )
     2 dos: go to repro root path
          D:\svn>
     3 D:\svn> svnadmin load 7thOnline <d:\svn_backup\46988.dmp
     4 update 0 version file

    NOTE:
              Issue 1
                     D:\svn>svnadmin load 7thOnline <d:\svn_backup\46988.dmp
                        <<< Started new transaction, based on original revision 46988
                             * editing path : 2012Q2-GA5.4.1 GRI/JavaDev/cmm/data/ADDataParser.java ...
                        done.
                       
                        ------- Committed new rev 46998 (loaded from original rev 46988) >>>
                       
                        <<< Started new transaction, based on original revision 46989

                        .svnadmin: File already exists: filesystem '7thOnline/db', transaction '46998-1'
                        , path '2012Q2-GA5.4.1 GRI/JavaDev/cmm/data/RatioCalculator.java'
                       
                Solution:
                        remove related version file
                        change 0 and current info to keep current version to be dump start version - 1 (here is 46987).

                Issue2:
                    C:\Documents and Settings\ntadmin>svnsync sync repo_local_path
                    svnsync: Revision being currently copied (47009), last merged revision (47008),
                    he destination without using svnsync?
           
               Solution:
                    update 0 version file
