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

Sat, 11 May 2013 12:43:23 -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-79] Create bucket function does not allow user to set the bucket type

Sat, 26 Jan 2013 09:14:33 -0600

Create bucket function does not allow user to set the bucket type

We should add the bucket type to the list of parameters

it is possible to work around this with the rest interface like:
couchbase = Couchbase("127.0.0.1:8091", "Administrator", "password")
#get the rest interface
rest = couchbase._rest()
rest.create_bucket(bucket='myBucket',
                   ramQuotaMB=160,
                   authType='sasl',
                   saslPassword='password',
                   replicaNumber=0,
                   bucketType='couchbase')

[PYCBC-27] support errors on views

Dependency — Fri, 26 Apr 2013 20:10:59 -0500

Views now have some options on capturing errors and stopping on errors as documented here:
http://www.couchbase.com/docs/couchbase-manual-2.0/couchbase-views-writing-errors.html

The client needs to support these.

[PYCBC-37] Highlevel synchronous mutation operations atop observe

Highlevel synchronous mutation operations atop observe

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

Fri, 26 Apr 2013 20:10:59 -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-36] Implement observe command

Fri, 26 Apr 2013 20:10:59 -0500

Add the basic low level observe command

[PYCBC-71] Supporting _all_docs in the SDK

Fri, 26 Apr 2013 20:11:00 -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-9] an interface to paginate across large view results is needed

Fri, 26 Apr 2013 20:11:01 -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:
http://guide.couchdb.org/draft/recipes.html#pagination

[PYCBC-82] Error handling documentation

Fri, 26 Apr 2013 20:11:03 -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-42] Add a unit/integration test validation of OBSERVE + view stale=false

Fri, 26 Apr 2013 20:11:02 -0500

Ensure that when a synchronous set is used with the new low-level observe, the index is fully updated when querying with view=false.

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

Fri, 26 Apr 2013 20:11:03 -0500

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

[PYCBC-113] TOC for Python 1.0

Wed, 15 May 2013 19:02:13 -0500

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

[PYCBC-68] cannot delete design doc

Fri, 17 May 2013 14:27:00 -0500

This may be related to the _rev changes with design docs recently. It could also be related to authentication changes.

[PYCBC-41] View error options at query time

Dependency — Fri, 17 May 2013 14:27:18 -0500

At view query time, we need to ensure the developer has the ability to add an "on_error" parameter with values of either "stop" or "continue".

[PYCBC-64] Improve design document management error handling

Fri, 17 May 2013 14:28:08 -0500

[PYCBC-38] Replica read command

Implement a simple replica read command

[PYCBC-83] Python client fails to encode view parameters

Tue, 21 May 2013 08:59:23 -0500

http://www.couchbase.com/forums/thread/reporting-issue-python-client-bucket-viewoptions-needs-encode-options

During querying a view, if the option is not encoded, it generates an error.
Example:
bucket.view("_design/beer/_view/by_name", limit=10, key="##")
The "##" characters generates:
"invalid UTF-8 JSON: {{error,insufficient_data},"[\"NONE"}"
The Couchbase Python client code should encode all the params in the client.py: view() method.

Please follow up with the user who posted the issue on the forums once this issue is resolved.

[PYCBC-8] creating and destroying design docs with views from the client library should be available

Fri, 26 Apr 2013 20:10:57 -0500

Separate from accessing views, there should be methods of creating and destroying views and the associated design documents.

[PYCBC-12] client should provide some way of asynchronously running multiple ops in parallel

Fri, 26 Apr 2013 20:11:01 -0500

Currently, if one has to get multiple items to do something, they must all be done in serial.

get A
get B
get C

print "A + B + C is " A + B + C

it'd be better if A, B and C could all be fetched without blocking, and only when going to access them, would the request be blocked.
