commit b4a78c72dc74158b2e2f62f8fd38915cea07add0 Author: Isis Lovecruft <isis(a)torproject.org> Date: Tue Jun 10 21:59:31 2014 +0000 Deprecate bridgedb.Bridges.is_valid_fingerprint(). * MOVE bridgedb.Bridges.is_valid_fingerprint() to bridgedb.test.deprecated module for regression testing. * REMOVE bridgedb.Bridges.toHex(). * REMOVE bridgedb.Bridges.fromHex(). * REMOVE bridgedb.Bridges.HEX_FP_LEN. * ADD bridgedb.parse.fingerprint module. This now contain equivalent functionality to the above removed/moved objects. * ADD monkeypatcher code for all the above removed/moved code to bridgedb.test.test_Tests suite for regression testing. --- lib/bridgedb/Bridges.py | 29 ++++++------------------ lib/bridgedb/parse/fingerprint.py | 44 +++++++++++++++++++++++++++++++++++++ lib/bridgedb/test/deprecated.py | 33 ++++++++++++++++++++++++++++ lib/bridgedb/test/test_Tests.py | 6 +++++ 4 files changed, 90 insertions(+), 22 deletions(-) diff --git a/lib/bridgedb/Bridges.py b/lib/bridgedb/Bridges.py index 2439130..5b5e678 100644 --- a/lib/bridgedb/Bridges.py +++ b/lib/bridgedb/Bridges.py @@ -10,7 +10,6 @@ them into hashrings for distributors.

[bridgedb/master] Make `isValidIP()` backwards compatible with deprecated `is_valid_ip()`.

commit ee0ba04f6345b22c9adea0a7eb7761cfb5558fb1 Author: Isis Lovecruft <isis(a)torproject.org> Date: Wed Jun 11 00:10:21 2014 +0000 Make `isValidIP()` backwards compatible with deprecated `is_valid_ip()`. The old `bridgedb.Bridges.is_valid_ip()` function expected a single string parameter, and would return a boolean. The new `bridgedb.parse.addr.isValidIP()` function expected an `ipaddr.IPAddress` as a parameter. * CHANGE `bridgedb.parse.addr.isValidIP()` to convert any strings which it receives as arguments into `ipaddr.IPAddress`s, which makes it backwards compatible with the (deprecated) `bridgedb.Bridges.is_valid_ip()` function. --- lib/bridgedb/parse/addr.py | 47 +++++++++++++++++++++++++------------------- 1 file changed, 27 insertions(+), 20 deletions(-) diff --git a/lib/bridgedb/parse/addr.py b/lib/bridgedb/parse/addr.py index 01acf58..750ed78 100644 --- a/lib/bridgedb/parse/addr.py +++ b/lib/bridgedb/parse/addr.py @@ -396,34 +396,41 @@ def isValidIP(ip): >>> isValidIP('xyzzy') False - :type ip: An :class:`ipaddr.IPAddress`, :class:`ipaddr.IPv4Address`, or - :class:`ipaddr.IPv6Address`. - :param ip: An ``ipaddr.IPAddress`` class. + :type ip: An :class:`ipaddr.IPAddress`, :class:`ipaddr.IPv4Address`, + :class:`ipaddr.IPv6Address`, or str + :param ip: An IP address.
