大话人生

常用的svn命令的一个简要介绍，很有用的：
CREATE REPOSITORY

$ svnadmin create /usr/local/svn/newrepos

IMPORT MODULE

$ svn import mytree file:///usr/local/svn/newrepos/fooproject
Adding mytree/foo.c
Adding mytree/bar.c
Adding mytree/subdir
Adding mytree/subdir/quux.h
Committed revision 1.

START STANDALONE SVN SERVER

svnserve.exe -d -r d:/temp/repos

STARTING SVN UNDER APACHE

  DAV svn
  SVNPath d:/Data/SVN
  AuthType Basic
  AuthName "Subversion repository"
  AuthUserFile d:/Data/SVN/svn-auth-file
  Require valid-user

Would be available using:

svn co http://ip:port/path/to/repo/

ENABLING SIMPLE AUTHORIZATION

1) create passw file:

htpasswd -cm d:/Data/svn-auth-file

add pass:

htpasswd -m d:/Data/svn-auth-file

2) create svn-policy-file file:

[groups]
project1-developers = anton, mike
project2 = anton, mike, peter
[project1:/]
@project1-developers = rw
[project2:/]
@project2-developers = rw

3) httpd.conf:

  DAV svn
  SVNPath d:/Data/SVN
  AuthType Basic
  AuthName "Subversion repository"
  AuthUserFile d:/Data/svn-auth-file
  Require valid-user
  AuthzSVNAccessFile d:/Data/svn-policy-file

ENABLING SVN TRAFFIC COMPRESSION

It is required to invoke mode_deflate in httpd.conf:

DeflateBufferSize 8096
DeflateCompressionLevel 9

...

  SetOutputFilter DEFLATE
  SetInputFilter DEFLATE
  DAV svn
  SVNPath d:/temp/repos
  AuthType Basic
  AuthName "Subversion repository"
  AuthUserFile d:/temp/svn-auth-file
  Require valid-user

EXTRACTING ONE PROJECT FROM MULTIPROJECT REPOSITORY

1) Dumping repos:

svnadmin dump d:datasvn > repo-dump
or svnadmin dump myrepos --revision 100:200 > revs-100-200.dumpfile

2) taking 1 project from repo:

type repo-dump | svndumpfilter include project1 > project1-dump

3) removing root dir:

Node-path: project1
Node-action: add
Node-kind: dir
Content-length: 0

Replace all "Node-path: project1/" strings with "Node-path: "

4) creating repo:

svnadmin create d:datasvnproject1

5) restoring:

svnadmin load d:datasvnproject1 < project1-dump

6) browsing

svnlook tree d:datasvn

7) Configuring Apache:

  SetOutputFilter DEFLATE
  SetInputFilter DEFLATE
  DAV svn
  # any "/svn/foo" URL will map to a repository /usr/local/svn/foo
  SVNParentPath d:/Data/SVN
  AuthType Basic
  AuthName "Subversion repository"
  AuthUserFile d:/Data/svn-auth-file
  Require valid-user

8) Switch all working copies to a new repository:

[to a new branch] svn switch http://newIP:newPort/path/to/repo
[to a new URL] svn switch --relocate http://oldIP:oldPort/path/to/repo http://newIP:newPort/path/to/repo

BERKLEY DB recovery

1) download appropriate bdb release from berkley site

2) build win tools usinn VC 6.0+

3) run db_recover -vec -h d:datasvnproject1

4) move _db files from d:datasvnbroker into d:datasvnproject1db folder

5) if fail problem persists, after 4th step do backup/restore svn repo:

 
 svnadmin dump d:datasvnproject1 > project1.timestamp.dump
 
 svnadmin create d:datasvnproject1
 svnadmin load d:datasvnproject1 < project1.timestamp.dump
