This is an automated email from the git hooks/post-receive script.
martin-schanzenbach pushed a commit to branch master
in repository gnunet.
commit 93cd93a1330fb38add615f797ac9a87fc252ff98
Author: Andreas Ebner <address@hidden>
AuthorDate: Sat Aug 3 13:01:22 2019 +0200
Updated fw/bw algo, collect, and verify (still some things left to do)
- collect/verify now use delegate instead of credential
- parameter in api messages to indicate the direction of the resolution
- fw algo sets delegation_chain and ref_count on solution find
- namestore lookup instead of iteration to get all delegates from
starting/goal subject
