@@ Zeile 161: / Zeile 188: @@
 According to http://svn.haxx.se/dev/archive-2002-08/1385.shtml there is no command like the ''release'' of CVS. Just delete the working copy locally.
-==== Move Files and Dirs ==
+==== Branching ==
+=== Intro ==
+A branch is created simply by [[svnbook>1.5/svn.branchmerge.using.html#svn.branchmerge.using.create|making a copy]] of the project. SVN knows only how to copy. Copies may have the [[svnbook>1.5/svn.branchmerge.using.html#svn.branchmerge.using.concepts|meaning]] of branches or tags.
+It is recommended to do the copy on the server, not locally. The remote copy also includes the commit in one step. Eg:
+  svn cp http://url/project/trunk http://url/project/branches/foo -m "Creating a branch for working on feature foo"
+  svn checkout http://url/project/branches/foo
+  project
+  |-- branches
+  |   `-- foo
+  |-- tags
+  `-- trunk
+=== Use Cases ==
+  * Try out a new feature in a separate branch without disturbing the trunk
+  * Create a branch from an older revision to make a bug fix
+  * FIXME Create client-specific variants of the same main project eg. for special needs of customers
+==== Merging ==
+=== Intro ==
+<note tip>Merging ([[svnbook>1.5/svn.branchmerge.advanced.html#svn.branchmerge.advanced.advancedsyntax|explanation]] / [[svnbook>1.5/svn.ref.svn.c.merge.html|manpage]]): Apply the changes between repository tree X and repository tree Y into the working directory. Any revision on any branch is a repository tree.</note>
+  * FIXME Verify: Merging is not symmetrical, i.e. if a line was added to a file between rev X and rev Y, than ''merge X Y'' will add that line to the file in the working dir and ''merge Y X'' will //remove// that line!
+  * Merging can not just happen between branches, but also between older revisions in the same branch
+  * Merging does not always need to cover the whole project, it can be restricted to subdirs or single files. See also [[svnbook>1.5/svn.branchmerge.basicmerging.html]] -> selectively “copy” changes
+  * Have a //clean// working directory before merging :!:
+  * It is also possible to specify only one repository tree source (e.g. the tunk) with the merge command. In this case, all modifications of the trunk since you first created your branch (which you work on) are applied to the working dir. Used e.g to [[svnbook>1.5/svn.branchmerge.basicmerging.html#svn.branchemerge.basicmerging.stayinsync|keep a branch in sync]].
+  * For merging finishd branches which are to be discontinued and merged back into the trunk, the ''--reintegrate'' option is [[svnbook>1.5/svn.branchmerge.basicmerging.html#svn.branchemerge.basicmerging.stayinsync|necssary]]
+  * AFAIK it is not possible to easily keep two branches in sync (merge in both directions) like in [[mercurial_tips#merging|Mercurial]]. Basic merging in SVN is meant to frequently update branches from the trunk and finally reintegrate the branch into the trunk. To keep two branches in sync, advanced merging (with manual bookkeeping about what has already been merged) is necessary.
+=== Use Cases ==
+  * Merge a new feature in a separate branch into the trunk
+  * Merge bug fixes of an older revision into the trunk
+  * FIXME Merge common parts of client-specific branches
+  * Undo committed Changes, see below
+==== Undoing Changes ==
+=== Undoing lokal Changes ==
+See [[svnbook>1.4/svn.ref.svn.c.revert.html|revert]]
+=== Undoing committed Changes ==
+  svn merge [--dry-run] -r 627:480 http://url/project
+This command removes all changes which have been done between r480 and r627 //in the workin copy//. Afterwards a commit is necessary.
+See also [[svnbook>1.4/svn.branchmerge.commonuses.html]] -> Undoing Changes
+=== Commit Log Message Correction ==
+Example:
+  svnadmin setlog /path/to/repository --bypass-hooks logmessage.txt -r 25120
+See also: [[svnbook>1.5/svn.reposadmin.maint.html#svn.reposadmin.maint.setlog|Svnbook]]
+==== Locks ==
+View locks:
+  svn st -u
+  * O: Lock from someone else
+  * K: Own lock
+Create and remove locks:
+  svn lock file
+  svn unlock file
+[[svnbook>1.7/svn.advanced.locking.html|more]] -> from "Discovering Locks" on
-  svn move <from> <to>
-Work just like shell ''mv'' command :-) See  [[svnbook>svn.ref.svn.c.move.html]]
