commit 225d504fcf7b36df7fb9f0f36c5dc07c1d4cb6ed Author: Karsten Loesing karsten.loesing@gmx.net Date: Mon Aug 20 20:47:55 2018 +0200

Remove redundant escape in regular expressions.

Turns out that characters inside square brackets don't need to be escaped. In fact, "^[0-9\.]{7,15}$" does not only match valid IPv4 addresses but also strings like "1\2\3\4". --- .../java/org/torproject/onionoo/server/ResourceServlet.java | 10 +++++----- .../java/org/torproject/onionoo/updater/LookupService.java | 2 +- 2 files changed, 6 insertions(+), 6 deletions(-)
