svndumpfilter

  • 由於 trac 的 svn 裡有 hadoop4win-setup 目錄,而 sourceforge 的 svn 紀錄是新的,所以想試試看能否合併。
    • [參考] SourceForge 的 SVN 匯入文件有提到 Filtering the dump file (optional)
    • [參考] SVNBOOK 也有提到 Filtering Repository History
    • 採用 SVNBOOK 的步驟,首先把 hadoop4win 的部份獨立成一個 Repository
      jazz@Wdebian:~/trac_pool/trac_pool/grid$ svnadmin dump svnroot/ > grid_svn_dumpfile
      .......
      * Dumped revision 248.
      jazz@Wdebian:~/trac_pool/trac_pool/grid$ svndumpfilter include --drop-empty-revs --renumber-revs hadoop4win-setup <  grid_svn_dumpfile > hadoop4win_dumpfile
      jazz@Wdebian:~/trac_pool/trac_pool/grid$ svnadmin create hadoop4win
      jazz@Wdebian:~/trac_pool/trac_pool/grid$ svnadmin load --ignore-uuid hadoop4win < hadoop4win_dumpfile 
      ........
      ------- Committed revision 30 >>>
      jazz@Wdebian:~/trac_pool/trac_pool/grid$ rm grid_svn_dumpfile hadoop4win_dumpfile
      jazz@Wdebian:~/trac_pool/trac_pool/grid$ mv hadoop4win ~/hadoop4win_trac
      
    • 做到這一步,我們可以拿到一個只有 hadoop4win-setup 這個目錄的 svnroot。(這裡我多用了 --drop-empty-revs 跟 --renumber-revs 兩個參數,如此可以讓原本 248 個 changeset 的 grid repository 過濾成只有 30 個 changeset 的 hadoop4win repository.
    • 根據 sourceforge 的說明,可以用 rsync 方式取回
      jazz@Wdebian:~$ mkdir -p hadoop4win_sf
      jazz@Wdebian:~$ cd hadoop4win_sf/
      jazz@Wdebian:~/hadoop4win_sf$ rsync -av hadoop4win.svn.sf.net::svn/hadoop4win/* .
      jazz@Wdebian:~/hadoop4win_sf$ cd
      jazz@Wdebian:~$ svnadmin dump hadoop4win_sf/ > hadoop4win_sf_dumpfile
      ..........
      * Dumped revision 15.
      jazz@Wdebian:~$ svnadmin load --ignore-uuid hadoop4win_trac/ < hadoop4win_sf_dumpfile 
      ..........
      ------- Committed new rev 45 (loaded from original rev 15) >>>
      
  • 做到這一步,算是完整地將整個專案 SVN 合併成一個。好在時間點兩個是相互錯開的,不然還真不知道怎麼根據時間點順序做合併呢!
  • 接著把這個 SVN repository 用 svnadmin dump 指令先產生一個 hadoop4win_dumpfile 的檔案。然後 scp 到 shell.sf.net
    jazz@Wdebian:~$ svnadmin dump hadoop4win_trac/ > hadoop4win_dumpfile
    ....
    * Dumped revision 45.
    jazz@Wdebian:~$ scp hadoop4win_dumpfile jazzwang,hadoop4win@shell.sf.net:.
    
  • 登入 shell.sf.net
    jazz@Wdebian:~$ ssh -t jazzwang,hadoop4win@shell.sf.net create
    [jazzwang@shell-24009 ~]$ adminrepo --checkout svn
    [jazzwang@shell-24009 ~]$ rm -rf /svnroot/hadoop4win/*
    [jazzwang@shell-24009 ~]$ svnadmin create /svnroot/hadoop4win
    [jazzwang@shell-24009 ~]$ svnadmin load --ignore-uuid /svnroot/hadoop4win/ < hadoop4win_dumpfile 
    [jazzwang@shell-24009 ~]$ adminrepo --save svn
    
    **** Ignoring the contents of the hooks directory (hooks are managed via the web) ****
    
    Save and unlock the svn repository for hadoop4win? [ny] y
    
  • 這樣就算是完整把整個開發過程移植到 sourceforge 去啦!!!!大功告成!!!
  • 同步上去以後,ViewCV 的結果是正確的,不過 trac 不正確。出現底下的錯誤訊息,只好請 sourceforge 管理員幫忙了~開單
    Warning: Can't synchronize with the repository (The 'repository_dir' has changed, 
    a 'trac-admin resync' operation is needed.). Look in the Trac log for more information.
