Subversion.

Where palced config files?

The per-user configuration area currently contains three files two configuration files ('config' and 'servers').

/etc/subversion
Unix system wide configurations.
$HOME/.subversion
Unix per-user configuration area.
%APPDATA%\Subversion
Windows per-user configuration area.

Coping repository.

Making local repository copy:

$ svnadmin create $SVNROOT
$ svnsync init file://$SVNROOT svn://$REMOTE
$ svnsync synchronize file://$SVNROOT

Note that you can't relocate working copy to new repository copy becase of:

$ svn relocate file://$SVNROOT
svn: E195009: The repository at 'file:///home/user/devel/repo-copy' has uuid 'b064fe9f-b7ba-459e-afdf-3429ad89a318', but the WC has '11827c6b-1af5-4614-8a8b-dda7fb34cd94'

Coping repository from SourceForge to GoogleCode:

$ svnsync init https://PROJ.googlecode.com/svn https://PROJ.svn.sourceforge.net/svnroot/PROJ
$ svnsync --username NAME --password PASSWORD \
              sync https://PROJ.googlecode.com/svn https://PROJ.svn.sourceforge.net/svnroot/PROJ

Disable interactive conflict resolution.

Write in $HOME/.subversion/config:

[miscellany]
interactive-conflicts = no

Creating svn repo.

$ mkdir -p /srv/svn
$ svnadmin create /srv/svn/$repo
$ svn co file:///srv/svn/$repo $repo
$ cd /tmp/$repo
$ mkdir trunk branches features tags
$ svn add *
$ svn st      # check all OK
$ svn ci -m "Init repo."

For multi-project repo do follow:

$ mkdir -p /srv/svn
$ svnadmin create /srv/svn/$repo
$ svn co file:///srv/svn/$repo $repo
$ cd /tmp/$repo
$ for proj in $proj1 $proj2; do mkdir $proj/trunk $proj/branches $proj/features $proj/tags; done
$ svn add *
$ svn st      # check all OK
$ svn ci -m "Init repo."

Run local svn server.

$ svnserve -d --pid-file=svnserve.pid --root=/srv/svn/proj  # default port: 3690
$ svn ls svn://localhost    # check all OK
$ kill -l

Undo bad commit.

$ emacs FILE
...
$ svn ci -m "Introduce first bug."
Sending        trunk/FILE
Transmitting file data .
Committed revision 7.
$ emacs FILE
...
$ svn ci -m "Make a lot of good changes."
...
Committed revision 8.
...
$ emacs FILE
...
$ svn ci -m "Introduce second bug."
...
Committed revision 10.
$ emacs FILE
...
$ svn ci -m "Make a lot of good changes."
...

Now you understand that revision 7 and 10 buggy. You decide revert changes:

$ svn merge -r 7:6 -r 10:9 FILE
$ svn ci -m "Reverted revision 7 and 10."

For one changeset revert you can use shortly syntax:

$ svn merge -c -7 -c -10 FILE

Also you can use ranges:

$ svn merge -r 10:6 FILE

Merge branches.

$ cd trunk
$ svn mergeinfo --show-revs eligible ^/branches/feature
$ svn merge ^/branches/feature
$ svn ci -m 'Integrate feature X.'

Fix EOL style.

$ find . -type f -name '*.java' -exec svn propset svn:eol-style native {} ';'
$ svn ci -m 'Fix svn:eol-style.'

Note that this actions pollute history. For example every line of file with CR/LF (created on Windows on file without svn:eol-style native) after this actions would have new author in svn annotate, and svn diff will show all on all change.
