Changelog

1.1.0

• Support Riak 2.0 (see https://github.com/mostlyserious/riak-js/pull/225)

1.0.3

• Fix a bug with buckets stream
• Add possibility to overwrite timeout value in Poolee for any requests

1.0.2

• Fix javascript error when we use data with an error
• options.keys / options.buckets are now taken into account with client.keys / client.buckets

1.0.1

• Remove useless console.log
• Attach response headers to error, enabling for example tombstone detection on 404.
• Allow user to override the riak port with HTTP_PORT / PB_PORT environement variables
• Fix a streaming error with node.js 0.10.x

1.0.0

• Using riakpbc 2.1 : dropping support for node 0.8 / dropping support for non-streams on protobuf for keys and buckets retrievals.
• Fix Travis CI
• Cleaner dependencies

0.10.2

• Fix HTTP status codes intepreted as errors when using the connection pool (github.com/chirag04 and github.com/domasx2)

0.10.1

• Support for HTTP connection pooling (github.com/andrewjstone)
• Fix unwanted errors in ping and save operation callbacks (github.com/matehat)

0.10.0

• Preliminary support for Protocol Buffers via a single connection.
• Fetch siblings by default, restoring previous riak-js behavior
• Populate meta.links when saving an object based on the response's HTTP headers (github.com/accelerated)
• Fix content length override. Allows handing in streaming data from e.g. connect.js. (github.com/englercj)
• Only set the language attribute on map and reduce phases. Avoid setting it on phases where it's not according to spec. (github.com/accelerated)

0.9.3

• Switch testing framework to mocha/should.js (github.com/kenperkins)
• Remove requirement of a Unix system from package.json (github.com/yawnt)
• Fix a global leak of HttpSearchMeta (github.com/brianedgerton)

0.9.2

• Fix Search options so it handles hostname and port (github.com/kenperkins)
• Fix unwanted vector clock overwriting during link walking (github.com/TauZero)
• Handle connection errors gracefully so that they don't kill the process

0.9.1

• Request instrumentation for metrics, logging, etc.
• Fix a leak in Httpmeta (github.com/rkusa), (#134)
• Handle content length properly for Unicode data (#132)
• Fix MapReduce options so it handles hostname and port (github.com/spencergibb)
• Add support for link-walking (github.com/TauZero)
• Handle JSONified error messages (github.com/spencergibb)
• Fix parsing of links on get requests (github.com/TauZero)

0.9.0

• Complete rewrite in JavaScript (two reasons: better debugging in production deployments, and more people can contribute)
• Support Riak 1.0 features
• First class support for streams (Luwak, key listing, Map/Reduce, logging)
• Faster testing with node-seq + assert
• Extra HTTP headers can now be passed in via headers (for instance custom usermeta, X-Riak-Meta-*) - these will override whatever has been set elsewhere
• addSearch is now search
• The project is open for other implementations
• Removed Protocol Buffers support – contributions welcome (extend Client in a file called protobuf-client.js along with a protobuf-meta.js)
• A client-side impl is also possible (look at https://github.com/ded/reqwest)
• Support for Riak Search, including adding and removing documents directly. Search is namespaced on the client separately: riak.search.find('users', 'email:[email protected]')
• Moved MapReduce to a separate namespace on the client to separate concerns in a nicer way: riak.mapreduce.add('users').run()

TODO

• Unify meta in all responses (check getAll, chunked map/reduce) - meta should allow for fine-grained mappings
• SSL support
• Use path internally but don't expose it as API (see path branch), to prepare for new URIs in Riak 1.0
• More rigorous test suite (port from master)

LATER

• Integrate test backend

0.4.1

• Add search params [gpascale]
• SSL client [isaacs]
• Last-modified date patch [siculars]
• Add meta.noError404 so that you can prevent 404s from showing up as errors [syrio]
• Deprecation warnings

0.4.0

• db.update: convenience method for updating documents
• Changed debug behaviour: always log to stdout. Not providing a callback will output to console.log regardless of the setting

0.4.0rc3

• Allow headers to override, useful for reverse proxies sitting between node and Riak
• URI-encoding bucket/key is now an option (encodeUri)
• Add documentation for map/reduce arguments
• Remove agent from meta, which should fix critical bug (#64, #67)
• Allow logging to alternate streams. And default to stderr, not stdout (thanks Mark!)
• Add docs for host/port (thanks Ken!)
• Add the new presort property for Riak Search (thanks Greg!)

0.4.0rc2

• Major docs update => http://riak-js.org
• keys=stream emits keys events
• walk now accepts noJSON
• Support Map/Reduce timeout option
• Protobuf interface refactor (still experimental support in 0.4)
• Minor bug fixes

• npm 1.0 compatibility
• Minor bug fixes

0.3.6

• Fix index.js and package.json for npm compat
• Fix recursing usermeta
• Fix for luwak location parsing
• Updates related to Riak Search operations

0.3.0beta6

• Test backend implementation
• Connect session store
• Protobuf parsing is now more robust
• Replace client every time ECONNREFUSED occurs
• Initial Riak Search support
• Minor bugfixing and internals refactoring

0.3.0beta5

• Add support for bucket listing in HTTP (new Riak 0.14 feature)
