Description

When calling Subversion with relative paths there is a limit of 255 characters to the path length. If you call Subversion with an absolute path that no longer applies and you now have access to 32K chars. I have tried this myself and it does work. Try feeding SVN a path that is relative and is over 255 chars. It will not be able to complete the transaction. Now, try to the same path again only as an absolute path and it will successfully complete the transaction.

This bug was originally fixed for the update command, but still remains for the checkout command. There may be other command that are affected by this bug.

1. cd c:\a\very\long\paht\under\windows\xp\or\windows\2000
2. mvn scm:checkout -DconnectionUrl=scm:svn:http://myUrlHere
--> It says
[INFO] Executing: cmd.exe /X /C "svn --non-interactive checkout http://myUrlHere checkout"
[INFO] Working directory: c:\a\very\long\paht\under\windows\xp\or\windows\2000
[ERROR] Provider message:
[ERROR] The svn command failed.
[ERROR] Command output:
[ERROR] svn: Your .svn/tmp directory may be missing or corrupt; run 'svn cleanup' and try again
svn: Can't open file 'checkout\blabla....svn-base': Le chemin d'accès spécifié est introuvable.
3. If I execute svn --non-interactive checkout http://myUrlHere c:\a\very\long\paht\under\windows\xp\or\windows\2000\checkout : it works.
