[PYCBC-134] Client will crash if _multi methods are passed lists with duplicate keys

Client will crash if _multi methods are passed lists with duplicate keys

[PYCBC-137] Fix up connection.py module to conform to 'pep8'

Fix up connection.py module to conform to 'pep8'

[PYCBC-9] an interface to paginate across large view results is needed

Wed, 19 Jun 2013 13:58:05 -0500

There can be some situations where querying a view returns results that way too large for the client to handle. In these cases, either the client library API or implementation of some Python specific API can allow for one to iterate over Views which have very large results.

The Ruby client does this with streaming. The Java client does this with traditional pagination:

[PYCBC-139] unlock_multi does not complain about missing cas

unlock_multi does not complain about missing cas

[PYCBC-135] Allow transcoder to be either an instance or a class

Wed, 19 Jun 2013 13:57:43 -0500

There's been some confusion about folks passing a class object instead of an instance. It should be simple enough to check this during construction.

[PYCBC-132] Lock without TTL fails with 'encoding error'

Wed, 19 Jun 2013 13:57:38 -0500

This should fail with an ArgumentError instead. It also seems the value does end up being sent to the server.

[PYCBC-131] Return more informative error on empty string to get

Wed, 19 Jun 2013 13:57:32 -0500

couchbase.exceptions.CouchbaseError: <RC=0x7[Invalid arguments], Operational Error, Results=1, C Source=(src/multiresult.c,147)>

Should display the key or object.

[PYCBC-82] Error handling documentation

Wed, 19 Jun 2013 13:57:27 -0500

Please create some documentation specifying possible error/failures to operations, what they "look" like in the logs/exceptions/stack traces and what our recommendation is on how to handle them.

i.e. tmp_oom, timeouts (connection/operation/java-internal/etc), "get miss" (it's technically a failure, let's make it overly obvious what it means), CAS failure, add() failure, replace() failure,

Some of this should be covered in the API reference, but this bug is specifically for a single page where this information is aggregated that a customer/user could read about how to handle errors.

[PYCBC-138] _multi arith functions not setting amount properly

Wed, 19 Jun 2013 13:57:02 -0500

Fix in progress. This is because we don't have a nice python-level wrapper for these functions, so the delta is never set.

[PYCBC-136] quiet parameter not being passed from Couchbase.connect

Wed, 19 Jun 2013 13:56:57 -0500

quiet parameter not being passed from Couchbase.connect

[PYCBC-7] An interface to access Couchbase Views is needed

Wed, 19 Jun 2013 13:56:52 -0500

Need an interface to be able to access Couchbase Views. Even without the ability to create and delete views, accessing view results is important, as views can be created through the Web UI interface.

The specific implementation should be specific to, and familiar to the surrounding language and library, but it should have some general capabilities:
- List views from a given cluster
- Instantiate an Object that represents a view on a given cluster
- Assemble query parameters for a View
- Retrieve non-reduced results from a View
* Be able to get the underlying document from the non-reduced results (this request should flow over binprot)
- Retrieve reduced results from a View (the format is the same, but there is no associated docid)

[PYCBC-129] Develop Content: deliver create the content behind the agreed upon TOC

Relates to — Tue, 18 Jun 2013 17:05:58 -0500

Per major docs process, need to come up with all of the content behind our Python 1.0 documentation.

[PYCBC-71] Supporting _all_docs in the SDK

Tue, 18 Jun 2013 17:03:28 -0500

The Python SDK currently doesn't seem to support _all_docs at the moment.

I remember that it was possible in the past with something like `.view("_all_docs")`, but I think this is the wrong way to do it. _all_docs should really have its own method. The reasons are:

- _all_docs and Views are a different thing, this should not be hidden to the user
- _all_docs uses raw collation and not Unicode collation as Views do
- I'm not sure about this one, but it could be the case, that _all_docs also contains not yet persisted items (as opposed to views).

[PYCBC-57] Provide Error Handling Consistent with Other SDKs

Tue, 18 Jun 2013 17:00:55 -0500

Need to provides consistent error messages and error handling. Needs to be more consistent with other SDKS, and underlying memcached protocol

[PYCBC-36] Implement observe command

Tue, 18 Jun 2013 17:00:27 -0500

Add the basic low level observe command

[PYCBC-126] Provide better handling at fork

Tue, 18 Jun 2013 17:00:17 -0500

Provide better handling at fork

[PYCBC-43] Update the getting started to match the Beer sample DB

Tue, 18 Jun 2013 16:58:39 -0500

Once the sample DB has been integrated into the server, update the getting started (both on the web page and in the documentation) to use the sample database.

[PYCBC-130] Segmentation fault when specifying hos:port as host params

Using host="127.0.0.1:8091" instead of host="127.0.0.1", port=8091 causes fault. Not sure if it affects the most recent code base.

[PYCBC-128] Client crashes if invalid hostname is passed

Mon, 17 Jun 2013 20:39:14 -0500

    def test_invalid_hostname(self):
        self.assertRaises(InvalidError,
                          Connection,
                          bucket='default', host='12345:qwer###')

Will crash because the lcb_t object is not cleared when lcb_create fails.

[PYCBC-125] Add lock option for Connection object

Mon, 17 Jun 2013 20:39:00 -0500

Add an explicit option to the constructor to lock the object - to prevent simulatenous access from multiple threads.

[PYCBC-113] TOC for Python 1.0

Relates to — Fri, 14 Jun 2013 00:02:12 -0500

For the upcoming 1.0 Python client, we'll need to come up with a TOC. Likely something like MB-7714.
