I have not examined the code. I can say, however, in the years that I've 
been lurking on this list, I've *never* seen anyone report an issue with 
a file being corrupted in transit to the server. I assume that is 
because the answer to your question is emphatically, "yes".

Of course, it is open source, so you can go look at the code. I was 
curious whether I could find it. This seems like the right file. I see 
references to "checksum" in their, so that's promising.

It is worth noting that you can turn on the svn:eol-style property 
which may mean that the checksum of the file in the repository will not 
match the checksum in your working copy.

Of course, you might also use a tool like OWASP ZAP as a proxy between 
an HTTP client and an HTTP server, and mess with the packets being 
passed between the client and the server, and see what happens.

Looks like current version of Subversion 1.8.X is 1.8.16. If you want it 
to be the most correct, perhaps upgrade?
