RE: svnsync on large files

Hi Daniel,
you are a guru. I don't know why but it worked!

I guess the magic is in the difference of network transmission of svnsync vs svnrdump / svnadmin load

Are there suggestions from your side to avoid this error in the future?

Thank you very much for your help!!!

Regards
Thomas

The steps should be this:

f() {
  token="$USER@$(hostname):${RANDOM}:${RANDOM}"
  svn propset --revprop -r0 -- svn:sync-lock $token
  svn propget --revprop -r0 --strict svn:sync-lock | fgrep -q -- $token || return 1
  svn propset --revprop -r0 svn:sync-currently-copying 54618
  svnrdump dump -r54618 --incremental https://mysourceturl/repository >tmpfile
  svnadmin load /svnmirror/projektablage <tmpfile
  svn propset --revprop -r0 svn:sync-last-merged-rev 54618
  svn propdel --revprop -r0 svn:sync-currently-copying
  svn propdel --revprop -r0 svn:sync-lock }

Note:

1. Using the same metadata revprops and order as svnsync.

2. The fgrep is to make up for the svn:sync-lock not being taken atomically. (The cmdline client passes NULL for the ORIGINAL_PROPVAL argument of svn_client_revprop_set2().)

3. Using a tmpfile since the dumpfile format isn't truncation-safe.

4. $RANDOM isn't in POSIX; if not available, substitute the first N bytes from /dev/urandom.

5. Make sure to use the correct source URL on the dump command.

6. The hooks may need tweaking.

Cheers,

Daniel
