Filing an issue so this won't get lost.
First reported here:
new proplist function (svn_client_proplist4) where I can specify a
filter/search string. Because right now, the proplist function returns
all properties it finds (with depth infinity also for all paths). While
this is a lot faster now than in 1.6, it still takes a few seconds for
average sized working copies. Analyzing the bottlenecks I found that
most time is spent allocating memory for all the returned data.
With a filter string I could specify just a property name and get only
those properties/paths back that have that specific property set, which
would reduce the memory allocations a *lot* and therefore be much
faster. Best would be if I could specify not just one property to be
searched for but several, that way I could ask for e.g. all "bugtraq:"
properties we (and several other svn clients) use for integrating with
