svn_log won't cross the copy boundaries for you?

thanks, it only gets better ;-)  i can't take any of the credits for the good 
looks.. the css wizards at plone.org handled that.

that would be perfect! i guess this will be using the new repos uuids..

in case its of interest to anyone i'm attaching the code i just finished which 
returns a map of rev numbers to repo paths given a node (the pic above was a 
setup, no copies involved). its not very pretty nor perhaps useful ;-), other 
than looking at the algorithm..  it works ok for the minimal test cases i 
gave it.

thanks guys,

I am planning to make svn_fs_revisions_changed() go way, and replace
it with svn_fs_node_revisions() which will do the same thing that
revisions_changed() does, but will optionally return a path for each
revision in which the node changed.

i want to produce a line by line annotation/blame showing revision number and 
author for changes of a non-binary file node's contents. perhaps a picture is 
more clear.

http://objectrealms.net/projects/svn_browser/pics/Annotation.png

to do that i need to get a hold of node's path across all of its 
revisions_changed including copies to get ahold of its contents. currently 
doing that seems to be problematic, mainly due to expense of iterating 
through n*m upper bound of copy checks combinations of n, revision changes to 
the node, and m representing the number of hierarchical containers for the 
node (though in actuality the number is much less). i was hoping that there 
was another mechanism that svn provided for reconstructing a given node's 
path across revisions.

So...  svn_fs_revisions_changed isn't doing the job for you?  (Sorry,
I still don't really understand what you're trying to accomplish.)

not afaics... but svn log doesn't need to cross copy boundaries, it can just 
get a change revision set (including copy revs) and pick off log /author from 
the revision props, it doesn't need to get the path. i'd love to be told 
otherwise ;-)
