commit 805fd38d22e94205ac3d1dd204ba5e2742ba56d7 Author: Karsten Loesing karsten.loesing@gmx.net Date: Fri Nov 17 10:59:08 2017 +0100

Sort matches first by timestamp, then by fingerprint.

A while ago, in 92cbc07, we took out ORDER BY statements, because we didn't need them anymore in order to produce correct output. However, this also made the technical details part less readable with entries appearing in random order. Let's fix this by sorting results first by timestamp and then by fingerprint.

Fixes #24327. --- CHANGELOG.md | 2 ++ .../java/org/torproject/metrics/exonerator/QueryServlet.java | 11 +++++++++++ 2 files changed, 13 insertions(+)
