SVN：为什么命令“svnadmin load”在没有 pre-revprop-change 挂钩的情况下工作，但“svnrdump load”需要它？

Question

When loading SVN dump files using svnadmin load and svnrdump load , only svnrdump load requires using the pre-revprop-change hook even though both of these methods are changing the revision properties.

Why is it that svnrdump load requires this commit hook while svnadmin load does not?

For the following examples, this is the dump command used:

svnadmin dump /path/to/source/repo > dumpfile.svn_dump

This will work without pre-commit hook:

svnadmin load /path/to/dest/repo < dumpfile.svn_dump

This will not work unless there is a pre-commit hook:

svnrdump load file://path/to/dest/repo < dumpfile.svn_dump

I'm not sure if it matters, but these tests were all done on Windows 10 using SVN 1.8.10

Answer 1

svnrdump is a command that runs on the URL and may or may not have direct access to the repository.

To operate properly svnrdump load requires that the target repository have revision property modification enabled via the pre-revprop-change hook

Whereas svnadmin is an administrative tool that never runs on the URL and always needs direct repository access.

svnadmin is the administrative tool for monitoring and repairing your Subversion repository. svnadmin works via direct repository access (and thus can only be used on the machine that holds the repository), it refers to the repository with a path, not a URL

So all command from svnadmin will never executes hooks as it operates directly on the repository.
