D). About "steal lock"

Http://developer.51cto.com/art/201108/282082.htm

This option was originally intended to increase flexibility. When a file is locked by others, you can still use the "steal" method to forcibly take the lock. However, this is also causedCodeOne of the potential causes of the conflict, we decided to avoid it. The technology used here is the hook script. Hook script is actually some script files, and some bat scripts in windows. Whenever SVN performs some specific operations, such as "locked" and "submitted", it searches for the relevant hook script in the specified directory and executes it to pre-process the corresponding commands. We need to check whether "steal lock" is checked when the user applies to lock the file before locking. If this option is selected, the operation is interrupted, prompting the user that this option has been disabled by the system. The directory for storing the hook script is related to the code library path. My directory is E: repositorieshwchhooks. After installation by default there are already a number of templates, with tmpl extension, for example, the pre-lock.tmpl is to lock the pre-operation done before, the post-commit.tmpl is done after the submission of the pre-operation. We create a new file in: pre-lock.bat, and then enter the following content in it:
