How can I fix the SVN import line endings error?

Question

I have to import an huge SVN repository that I have to transfer from one server to another. So I exported it from the old server:

svnadmin dump . > archive.sv         


        

Answer 1

The first option of the answer of @ventura10 sounded good but didn't work for me. The sed command changed some versioned content outside the properties section resulting in md5 mismatches while loading the dump.

Because my repository has no properties with binary content I changed the sed command to correct all properties and not only svn:log and svn:ignore. I was also sure that no versioned file contained a line starting with Prop-content-length:. Otherwise I would have got an error when loading the dump.

sed -e '/^Prop-content-length: /,/^PROPS-END$/ s/^M/ /' svn.dump > svn.dump.repaired

It's important to replace ^M with [blank], because the size of the property value must not change.

The note of @ventura10 is still valid:

^M is a control character, that means 0D in hex. To get it use ^V^M (control V control M) instead ^M (circumflex M or control M)

It's hard to believe that upgrading an existing repository from svn 1.4 to svn 1.7 makes this step nessecary, but I've found no other way to get rid of the carriage returns that are no longer accepted since svn 1.6.
