Is there any way to svn diff or svn merge across multiple non-sequential revisions at once?

So in SVN you can do things like:

svn merge -r555:558
svn diff -c551

but (as far as I know) there is no way to do:

svn merge -r555:558, 592:594
svn diff -c551, 557, 563

For merges you can always just do several commands in sequence:

svn merge -r555:558
svn merge -r592:594

but for diffs doing that will just result in multiple diffs (and it's a little sub-optimal for merges too, as you can get conflicts from things that might just be removed in later revisions).

So, my question is ..开发者_运维知识库. is there any way, using either SVN itself or SVN combined with Linux commands, to do a true, no-sequential, multi-revision diff and/or merge?

You can merge multiple revisions in one command (at least in 1.6):

svn merge -c 551, 557, 563
svn merge -r 555:558 -r 592:594

however svn diff does not seem to support multiple non-sequential revisions.

To get a cumulative patch, you can get the diffs individually and then use combine-diff to merge them together one-by-one. It's not ideal, but you could write a script to automate the process.
