How to find where a component is referenced as svn:externals ?

[Gabriel SCOLAN <ga...@sagem.com>]

Dear all,

I'm facing an issue I'm sure many of you have already resolved : I've 
defined some software components (managed with thier own versions) in a 
library. The software projects I'm building are based on those components 
from the library. To do the "integration", I use the svn:externals 
properties that I find very useful on that use case. Now, to conduct an 
impact analysis when detecting a bug on a specific version of a component, 
I'm like to query the repository to know which are projects that are using 
that specific version of that specific component. First idea was to walk 
through the repository revisions interrogating each directory if it has in 
the property "svn:externals" a reference to that component version, but I 
suspect it is unefficient, as mentionned in the svnbook also (
http://svnbook.red-bean.com/en/1.5/svn-book.html#svn.advanced.props .. 
Searchability (or, Why Not  Properties)).

Could someone help me in finding an efficient solution to solve this ?

many thanks

gabriel
