svn undo last change

Suppose we want to undo the last ci (revision 100) back to 99 for the changes in current directory.

svn merge --revision 100:99 .

or

svn merge -c -100

svn ignore a file

The property is set on a directory. Below I created a file abc.txt and set svn:ignore on it:

$ touch abc.txt
$ svn propset svn:ignore abc.txt .
property 'svn:ignore' set on '.'
$ svn propget svn:ignore .
abc.txt

$ svn status --no-ignore
I      abc.txt
 M     .

Add with an editor:

svn propedit svn:ignore .

svn 1.4 compression

SVN 1.4 has compression support (use ldd to see if it is linked with libz). If use svn+ssh, enable ssh compression actually slows down the svn in my tests.

ldd /usr/bin/svn
...
libz.so.1 => /lib64/libz.so.1 (0x0000000020802000)
...
