问题
I am aware that this question was already asked answered on SO, but that answer was simply to remove the hook. I need to fix the hook instead of removing it.
We are running VisualSVN Server on Windows 2012 with Win 7 clients. I have been tasked with disabling the stealing of locks (I know this is not best practice use of SVN, but the bosses want it). Here is the .bat file I currently have in place for our pre-lock hook (found on the web):
@ECHO OFF
:: Set all parameters. Even though most are not used, in case you want to add
:: changes that allow, for example, editing of the author or addition of log messages.
set repository=%1
set rev_path=%2
set userName=%3
:: If a lock exists and is owned by a different person, don't allow it
:: to be stolen (e.g., with 'svn lock --force ...').
FOR /F "delims=: tokens=1*" %%a IN ('svnlook lock "%repository%" "%rev_path%"') DO if %%a==Owner (set LOCK_OWNER=%%b)
:: If we get no result from svnlook, there's no lock, allow the lock to
:: happen:
if "%LOCK_OWNER%"=="" (
exit /b 0
)
:: If the person locking matches the lock's owner, allow the lock to
:: happen:
if "%LOCK_OWNER%" = " %username%" (
exit /b 0
)
:: Otherwise, we've got an owner mismatch, so return failure:
echo "Error: %rev_path% already locked by %LOCK_OWNER%." >&2
exit /b 1
I have also tried writing an app using SharpSVN (I've used that to create a post-commit hook before). Both the .bat file and my SharpSVN script return this same error:
Lock token URI '
C:\Program Files\VisualSVN Server>"C:\Program Files\VisualSVN
Server\bin\VisualSVNServerHooks.exe" case-insensitive
-tC:\Repositories\DIT_TEST /go-home.txt Jeremy.Coulson
C:\Program Files\VisualSVN Server>C:\SVNAdmin\SVNPreLockHook.bat
C:\Repositories\DIT_TEST /go-home.txt Jeremy.Coulson
' has bad scheme; expected 'opaquelocktoken'
If you want to break the lock, use the 'Check For Modifications' dialog or the repository browser.
Here are the settings in our Visual SVN server:
I'm thinking that I have to somehow provide this opaquelocktoken to the hook script, but I'm not sure how.

If your problem is still actual, here is my way to avoid it.
The root cause is that SVN will take ANY "echoing" as a lock-token at pre-lock phase.
To avoid this I'm writing pre-lock hooks in vbs files (Visual Basic Script) which are to be run from pre-lock.bat hook file.
The pre-lock.bat file that run script is like this
@echo off
Wscript somescript.vbs %1 %2 %3 %4 %5
@echo on
Please note, that you have to use "Wscript" and not "Cscript"
When there is a need to use script result as exiting condition, then
@echo off
FOR /F "usebackq tokens=*" %%r in (`Cscript %1\hooks\somescript.vbs %1 %2 %3 %4 %5`) DO set res=%%r
@echo on
@exit %res%
The vbs way to pass value back to the .bat file is: Wscript.Echo some_value
