Chris Pickett commented on SVN-525:
-----------------------------------
The last time I looked at this in 2017, I was able to store binary files as
revprops to get around the pristine duplicate issue. But I didn't get further
than my notes below that add a binary file and get it back out. This is just a
simple proof-of-concept in case this idea is helpful.
{code:sh}
# create foo.mp3.md5 file with fields <sum> <bytes>
echo $(md5sum foo.mp3) $(wc -c foo.mp3) | awk '{print $1" "$3}' > foo.mp3.md5
# store foo.mp3 with bin:<sum> as the property name
svn propset bin:$(awk '{print $1}' foo.mp3.md5) --revprop -r 1 -F foo.mp3
# get the data back out as bar.mp3, stripping the trailing newline that svn adds
svn propget bin:$(awk '{print $1}' foo.mp3.md5) --revprop -r 1 | head -c $(awk
'{print $2}' foo.mp3.md5) > bar.mp3
# create bar.mp3.md5 file with fields <sum> <bytes>
echo $(md5sum bar.mp3) $(wc -c bar.mp3) | awk '{print $1" "$3}' > bar.mp3.md5
# the two mp3's are the same
diff foo.mp3 bar.mp3
# the two md5's are the same
diff foo.mp3.md5 bar.mp3.md5
{code}
So possibly even shell scripts could do everything. You might need a shadow
set of .md5 files that get committed.

> It's possible to make the cached pristine files in .svn/pristine/ optional.
> Doing so would be a huge storage savings on the client side, and would make
> Subversion even more compelling as a system for managing medium-large binary

> (Note that the cached pristine base versions used to be stored in
> .svn/text-base/, so you'll probably see references to that old location
> throughout this ticket. Also, there used to be one .svn/ directory per
> working tree directory; later that was changed to one .svn/ directory at the
> top of the working tree. Knowing that might also help clarify some of the
> older comments in this ticket.)
