When you connect to a Subversion server in Dreamweaver CS4, you receive the following error message:
SVN: #155021. You cannot update this file using Dreamweaver's Subversion integration because a newer Subversion client application on your machine has made updates to the file's Subversion meta data. For more information on this issue, see http://www.adobe.com/go/dw_svn_en.
The error message also appears inside a modal dialog or the background file transfer log.
To restore Subversion 1.4.5 client library compatibility, run the conversion script, which has been wrapped into a Dreamweaver extension.
The extension triggers a Python script, so make sure that you have the Python script interpreter installed on your local computer. For additional information, see Install Python on Windows, below.
Note: Python is installed as part of the default installation on Mac OS X.
Important: You can still change your site within Dreamweaver. This problem only occurs when you try to sync your site using the Subversion server. The issue doesn't affect other users on your machine as the change to the metadata is local to your machine. However, Dreamweaver can't interact with the server until you run the conversion script.
Note: You can run the script any time. If you touched your local site with another Subversion client program again, repeat steps 8-10.
Subversion development offers a script that converts the site's Subversion version meta data to 1.4.x, which is compatible with Dreamweaver.
In Windows, install it before running Subversion conversion.
The extension uses a Python script Subversion provides to convert your local site's meta data. (For more information, see http://subversion.tigris.org/faq.html#working-copy-format-change.) Extension Manager installs two files within your user folder. The first is the Python script (change-svn-wc-format.py). The other file is the extension's code, which is used to run the script directly from within Dreamweaver (DWSVNConvert.htm). After running the extension, an output file is also created, which contains conversion log messages (change-svn-wc-format.output.txt). In the event a problem occurs during conversion, errors are recorded in the output file.
The extension gets installed into the home directory in the following locations:
Windows path system and Python
The Python script doesn't run properly without having the PATH variable set on Windows which the Python installer doesn't set. To change this variable, edit the Environment Variables in Windows.
Using Adobe Dreamweaver and another Subversion client on the same computer can prevent your site from interacting with the Subversion server.
Third-party client software can update your local site's Subversion meta data to a newer client version, which is unsupported by Adobe Dreamweaver CS4.
Third-party Subversion clients can include:
You can find additional clients at Apache Subversion.
You're using Adobe Dreamweaver CS4, which supports the Subversion client libs 1.4.5. And you're using TortoiseSVN (1.5.x), which is supporting client version 1.5, on the same computer. Once you touch your local site using TortoiseSVN (for example, submit a file), the local Subversion meta data of your site is converted to version 1.5. Because of this conversion, Dreamweaver can no longer interact with the Subversion server. The newer Subversion client format is not backwards compatible with the 1.4 format supported by Dreamweaver.
