Re: SV: Feature request: unrevert

I haven't looked at how the revert API to the Subversion library works yet,
but I have some thoughts on this problem.

First, the "worst case scenario" is worse than what's referenced in that
link. If the recycle bin is disabled, and the user tries to revert
thinking that revert can undo a partial commit, then the files will be
gone.

Even if the only good place to invoke the recycle bin is from inside the
Subversion library, I think that would be a bad place to put it. The
recycle bin is a Windows Shell concept, and TortoiseSVN is a Windows Shell
app. Command line tools, even in Windows, don't tend to use Shell
extensions (for example, del doesn't have an option that says "send to
recycle bin").

Here's one way revert recycling can work:

o User selects files to revert
o Tortoise renames each file to a temporary name
o SVN revert is called
o If the revert fails, the renamed files are renamed back to their
original names, overwriting any partial revert
o If the revert succeeds, the new files are renamed to another temporary
name. The original files are renamed to their original names and sent to
the recycle bin. The new files are finally renamed back to their final
names.

Even though there is a bit of juggling going on, this generates the desired
result, doesn't have any negative side effects (at least none that I can
come up with) and isn't hard to implement.
