"Unable to parse reversed revision range" when merging from trunk to branch

[Jens Christian Restemeier]

I posted this already to the TortoiseSVN users list, but I think this issue may 
be on the client layer and not the tortoise interface.

 

I'm trying to catch up a branch with the changes on trunk. It seems to update 
the correct files, though at the end it fails with

"Unable to parse reversed revision range '19634-19631'"



I'm using TortoiseSVN 1.9.5 on Windows 8.1:



  X:\Subversion >s​vn --version
  svn, version 1.9.5 (r1770682)



I looked both on trunk and the branch for odd mergeinfo. Trunk has no mergeinfo 
newer than the branch (the last merge to it was ages ago). I did a search for 
those revisions on the branch, but they don't appear reversed:

  X:\Subversion>svn propget svn:mergeinfo --depth=infinity | find "19631"
  
/trunk:15014-19472,1​9473-19612*,19613-19​614,19615-19630*,196​31-19634,19635-20055​*



What exactly is that error message telling me, and how do I resolve it?

I did a google search, but the responses I found were for svn versions from 
years ago, or for svndumps.

I'm tempted to just copy everything over and to hack the mergeinfo manually, 
but I'm sure that'll cause more problems.

 

I just tried a “Test” merge in TortoiseSVN and that completed without that 
error.

 

Cheers,

Jens
