Automatically Remove Subversion Unversioned Files

Question

Hi,

does anybody know a way to recursively remove all files in a working copy that are not under version control? (I need this to get more reliable results in my automatic build VMware.)

Thanks, Stefan

Answer 1

Can you not just do an export to a new location and build from there?

Answer 2

I use this python script to do that:

import os
import re

def removeall(path):
    if not os.path.isdir(path):
        os.remove(path)
        return
    files=os.listdir(path)
    for x in files:
        fullpath=os.path.join(path, x)
        if os.path.isfile(fullpath):
            os.remove(fullpath)
        elif os.path.isdir(fullpath):
            removeall(fullpath)
    os.rmdir(path)

unversionedRex = re.compile('^ ?[\?ID] *[1-9 ]*[a-zA-Z]* +(.*)')
for l in  os.popen('svn status --no-ignore -v').readlines():
    match = unversionedRex.match(l)
    if match: removeall(match.group(1))

It seems to do the job pretty well.

Answer 3

this works for me in bash:

 svn status | egrep '^\?' | cut -c8- | xargs rm -i

The -i on the rm lets you confirm every delete.

Answer 4

My C# conversion of Thomas Watnedals Python script:

Console.WriteLine("SVN cleaning directory {0}", directory);

Directory.SetCurrentDirectory(directory);

var psi = new ProcessStartInfo("svn.exe", "status --non-interactive");
psi.UseShellExecute = false;
psi.RedirectStandardOutput = true;
psi.WorkingDirectory = directory;

using (var process = Process.Start(psi))
{
 string line = process.StandardOutput.ReadLine();
 while (line != null)
 {
  if (line.Length > 7)
  {
   if (line[0] == '?')
   {
    string relativePath = line.Substring(7);
    Console.WriteLine(relativePath);

    string path = Path.Combine(directory, relativePath);
    if (Directory.Exists(path))
    {
     Directory.Delete(path, true);
    }
    else if (File.Exists(path))
    {
     File.Delete(path);
    }
   }
  }
  line = process.StandardOutput.ReadLine();
 }
}

I couldn't get any of the above to work without additional dependencies I didn't want to have to add to my automated build system on win32. So I put together the following Ant commands - note these require the Ant-contrib JAR to be installed in (I was using version 1.0b3, the latest, with Ant 1.7.0).

Note this deletes all unversioned files without warning.

  <taskdef resource="net/sf/antcontrib/antcontrib.properties"/>
  <taskdef name="for" classname="net.sf.antcontrib.logic.ForTask" />

  <macrodef name="svnExecToProperty">
    <attribute name="params" />
    <attribute name="outputProperty" />
    <sequential>
      <echo message="Executing Subversion command:" />
      <echo message="  svn @{params}" />
      <exec executable="cmd.exe" failonerror="true"
            outputproperty="@{outputProperty}">
        <arg line="/c svn @{params}" />
      </exec>
    </sequential>
  </macrodef>

  <!-- Deletes all unversioned files without warning from the 
       basedir and all subfolders -->
  <target name="!deleteAllUnversionedFiles">
    <svnExecToProperty params="status &quot;${basedir}&quot;" 
                       outputProperty="status" />
    <echo message="Deleting any unversioned files:" />
    <for list="${status}" param="p" delimiter="&#x0a;" trim="true">
      <sequential>
        <if>
          <matches pattern="\?\s+.*" string="@{p}" />
          <then>
            <propertyregex property="f" override="true" input="@{p}" 
                           regexp="\?\s+(.*)" select="\1" />
            <delete file="${f}" failonerror="true" />
          </then>
        </if>
      </sequential>
    </for>
    <echo message="Done." />
  </target>

For a different folder, change the ${basedir} reference.

I ran across this page while looking to do the same thing, though not for an automated build.

After a bit more looking I discovered the 'Extended Context Menu' in TortoiseSVN. Hold down the shift key and right click on the working copy. There are now additional options under the TortoiseSVN menu including 'Delete unversioned items...'.

Though perhaps not applicable for this specific question (i.e. within the context of an automated build), I thought it might be helpful for others looking to do the same thing.

Answer 7

For the people that like to do this with perl instead of python, Unix shell, java, etc. Hereby a small perl script that does the jib as well.

Note: This also removes all unversioned directories

#!perl

use strict;

sub main()

{

    my @unversioned_list = `svn status`;

    foreach my $line (@unversioned_list)

    {

        chomp($line);

        #print "STAT: $line\n";

        if ($line =~/^\?\s*(.*)$/)

        {

            #print "Must remove $1\n";

            unlink($1);

            rmdir($1);

        }

    }

}

main();

If you are on windows command line,

for /f "tokens=2*" %i in ('svn status ^| find "?"') do del %i

Answer 9

See: svn-clean

Answer 10

If you are using tortoise svn there is a hidden command to do this. Hold shift whilst right clicking on a folder to launch the context menu in windows explorer. You will get a "Delete Unversioned Items" command.

see the bottom of this page for details http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-rename.html
