If in-db props are needed for pristine, then I don't think swapping their format numbers makes sense.
My only delay in performing the bump for in-db props is testing the upgrade code. We can cross our fingers, do the bump, and post-bump complete the upgrade testing. (the exposure would only be limited to people who run 'svn upgrade' and any devs who are using f16 right now) Cheers, -g On Fri, Jun 25, 2010 at 14:10, Philip Martin <philip.mar...@wandisco.com> wrote: > Compiling with SVN_EXPERIMENTAL_PRISTINE causes pristine text to be > stored in .svn/pristine/ using SHA1 filenames instead of > .svn/text-base/ using filenames derived from the working file.
