[tor-commits] [tor/release-0.2.8] Comment-out fallbacks in a way the stem fallback parser understands



commit 26146dbe9eb2404274b7c51121710f3f3529c930
Author: teor (Tim Wilson-Brown) <teor2345@xxxxxxxxx>
Date:   Thu Jun 23 10:49:03 2016 +1000

    Comment-out fallbacks in a way the stem fallback parser understands
    
    If we manually remove fallbacks in C by adding '/*' and '*/' on separate
    lines, stem still parses them as being present, because it only looks at
    the start of a line.
    
    Add a comment to this effect in the generated source code.

   o Minor features (fallback directory list):
     - Update hard-coded fallback list to remove unsuitable fallbacks.
       Resolves ticket 19071. Patch by teor.
+    - Add a comment to the generated list that explains how to comment-out
+      unsuitable fallbacks in a way that's compatible with the stem fallback
+      parser.
     - Update fallback whitelist and blacklist based on relay operator
       emails. Blacklist unsuitable fallbacks. Resolves ticket 19071.
