Description

The svn backend now supports excluding files through a
filterdiff-esque method: SVNClient._filter_diff. This
method looks through the output of svn diff for lines
that begin with Index: that mark the beginning of a
new file in the diff. If the file matches any given
patterns, it will not yield the lines corresponding to
that file's diff.

Testing Done

Ran rbt diff -X ... in an SVN repository and successfully
excluded files and empty files.

Show all issues

If for some reason there's text at the beginning of the diff before the first index line (which is valid), it will cause a NameError here, since include_file hasn't yet been set. Can you set include_file = True at the top of this function?

Change Summary:

Avoid NameError when diff includes lines before an Index: line

Can you add more details to this comment to describe what's happening in the change?

I'm also interested in why we're filtering and not using -x. Did it turn out that we couldn't pass that to SVN?

brennie Sept. 20, 2014, 9:37 a.m.

SVN calls out to external diff for each file, so if we run svn diff --diff-cmd=diff '-u -x pattern, then it runs a command like:
diff -L "f (rev x)" -L "f (rev y)" old new -x pattern f. However, if f matches the given pattern, it will still spit out the diff becuase it was called on that specific file (not with, e.g., diff -x pattern -r old/ new/).

Here too.

Also, minor thing, but we usually just use m for this variable. Not a big deal, but doesn't hurt to be consistent.

It turns out its not from svn diff. Its from SCMClient.convert_to_absolute_files.
It will always prepend the slash.
