MongoDB Wire Protocol server library

Project description

Mock server for testing MongoDB clients and creating MongoDB Wire Protocol servers.

Changelog

Next Release

MockupDB supports Python 3.4 through 3.8; it no longer supports Python 2.6 or Python 3.3.

New method MockupDB.append_responder to add an autoresponder of last resort.

Fix a bug in interactive_server with all_ok=True. It had returned an empty isMaster response, causing drivers to throw errors like “Server at localhost:27017 reports wire version 0, but this version of PyMongo requires at least 2 (MongoDB 2.6).”

Stop logging “OSError: [WinError 10038] An operation was attempted on something that is not a socket” on Windows after a client disconnects.

Parse OP_MSGs with any number of sections in any order. This allows write commands from the mongo shell, which sends sections in the opposite order from drivers. Handle OP_MSGs with checksums, such as those sent by the mongo shell beginning in 4.2.

1.7.0 (2018-12-02)

Improve datetime support in match expressions. Python datetimes have microsecond precision but BSON only has milliseconds, so expressions like this always failed:

server.receives(Command('foo', when=datetime(2018, 12, 1, 6, 6, 6, 12345)))

Now, the matching logic has been rewritten to recurse through arrays and subdocuments, comparing them value by value. It compares datetime values with only millisecond precision.

1.6.0 (2018-11-16)

Remove vendored BSON library. Instead, require PyMongo and use its BSON library. This avoids surprising problems where a BSON type created with PyMongo does not appear equal to one created with MockupDB, and it avoids the occasional need to update the vendored code to support new BSON features.

1.5.0 (2018-11-02)

Support for Unix domain paths with uds_path parameter.

The interactive_server() function now prepares the server to autorespond to the getFreeMonitoringStatus command from the mongo shell.

1.4.1 (2018-06-30)

Fix an inadvertent dependency on PyMongo, which broke the docs build.

1.4.0 (2018-06-29)

Support, and expect, OP_MSG requests from clients. Thanks to Shane Harvey for the contribution.

Update vendored bson library from PyMongo. Support the Decimal128 BSON type. Fix Matcher so it equates BSON objects from PyMongo like ObjectId(...) with equivalent objects created from MockupDB’s vendored bson library.

1.3.0 (2018-02-19)

Support Windows. Log a traceback if a bad client request causes an assert. Fix SSL. Make errors less likely on shutdown. Enable testing on Travis and Appveyor. Fix doctests and interactive server for modern MongoDB protocol.

1.2.1 (2017-12-06)

Set minWireVersion to 0, not to 2. I had been wrong about MongoDB 3.6’s wire version range: it’s actually 0 to 6. MockupDB now reports the same wire version range as MongoDB 3.6 by default.

1.2.0 (2017-09-22)

Update for MongoDB 3.6: report minWireVersion 2 and maxWireVersion 6 by default.

1.1.3 (2017-04-23)

Avoid rare RuntimeError in close(), if a client thread shuts down a socket as MockupDB iterates its list of sockets.

1.1.2 (2016-08-23)

Properly detect closed sockets so MockupDB.stop() doesn’t take 10 seconds per connection. Thanks to Sean Purcell.

1.1.1 (2016-08-01)

Don’t use “client” as a keyword arg for Request, it conflicts with the actual “client” field in drivers’ new handshake protocol.

1.1.0 (2016-02-11)

Add cursor_id property to OpGetMore, and ssl parameter to interactive_server.

1.0.3 (2015-09-12)

MockupDB(auto_ismaster=True) had just responded {"ok": 1}, but this isn’t enough to convince PyMongo 3 it’s talking to a valid standalone, so auto-respond {"ok": 1, "ismaster": True}.

1.0.2 (2015-09-11)

Restore Request.assert_matches method, used in pymongo-mockup-tests.

1.0.1 (2015-09-11)

Allow co-installation with PyMongo.

1.0.0 (2015-09-10)

First release.

0.1.0 (2015-02-25)

Development begun.
