Unreleased

  • [FIXED] Allow $and, $or, and $nor operator selectors to be used with only one expression selector.

2.19.1 (2020-07-03)

  • [FIXED] Connection leak regression introduced in 2.18.0 caused by not closing streams from successful session response bodies.
  • [UPGRADED] Optional OkHttp dependency to version 3.12.12.

2.19.0 (2020-03-02)

  • [NEW] Add getter for total row count to AllDocsResponse
  • [NEW] Added DbInfo#getSizes() for access to improved sizes information.
  • [FIXED] Corrected DbInfo#getDiskSize() to work with sizes object if disk_size is unavailable.
  • [FIXED] ViewMultipleRequest updated to preferentially use view queries format URL instead of deprecated format.

2.18.0 (2019-10-02)

  • [FIXED] Create an array of strings for QueryBuilder.fields() when a single field is provided.
  • [FIXED] Potential NPE creating exception messages.
  • [IMPROVED] Return exceptions directly from IAM token request failures instead of logging and deferring the request to the service with no credentials. The exception type is the same, but the message and cause are more clear and a round trip is avoided.
  • [IMPROVED] Prevent multiple session renewal requests happening simultaneously because some auth types apply limits to the number of requests that can be made.
  • [IMPROVED] Documented that for some database versions a call to get continuous changes may block when there are no changes available immediately.
  • [UPGRADED] Optional OkHttp dependency to version 3.12.5.

2.17.0 (2019-05-23)

  • [NEW] Added com.cloudant.client.api.model.DbInfo#getDocDelCountLong() to return deleted document count as a long instead of a String.
  • [DEPRECATED] com.cloudant.client.api.model.DbInfo#getDocDelCount().

2.16.0 (2019-04-01)

  • [NEW] Added database partition metadata fields for partitioned index count/limit.
  • [NEW] Added replication selector support.

2.15.0 (2019-02-12)

  • [NEW] Added option for client to authenticate with IAM token server.
  • [NEW] Added partitioned database support.
  • [FIXED] Updated the default IAM token server URL.

2.14.0 (2018-12-18)

  • [NEW] Add purge_seq getter on DbInfo class that returns sequence value as String.
  • [DEPRECATED] com.cloudant.client.api.model.DbInfo#getPurgeSeq().

2.13.1 (2018-09-05)

  • [FIXED] Regression that prevented keys being included as part of a ViewMultipleRequest.

2.13.0 (2018-06-06)

  • [NEW] Add CloudantClient.metaInformation() to get meta information from the welcome page.
  • [NEW] Add methods for interacting with the replicator _scheduler endpoint:
    • CloudantClient.schedulerJobs(),
    • CloudantClient.schedulerDocs(),
    • CloudantClient.schedulerDoc(docId).
  • [NEW] Add ComplexKey.addHighSentinel() to allow matching of all values as part of a complex key range.
  • [NEW] Support IAM authentication in replication documents.
  • [NEW] Add support for stable and update parameters in views.
  • [FIXED] Issues retrieving deleted documents using an AllDocsRequest.
  • [FIXED] An issue where getReason() returned an incorrect value for Response objects returned by Database.bulk().
  • [FIXED] Added missing _deleted field to Document model class.
  • [BREAKING CHANGE] The fix which adds _deleted to Document model class will break (de)serialisation for classes which sub-class Document and themselves declare a field which implicitly or explicitly has the serialised name of _deleted. The suggested work-around is to remove this field from classes which sub-class Document. For more details, see the javadoc for Document.
  • [DEPRECATED] OAuth authentication API targetOauth on the Replication class.
  • [DEPRECATED] stale parameter in views.
  • [IMPROVED] Added support for IAM API key in the client builder bluemix method.
  • [IMPROVED] When making view requests (including _all_docs), set keys in the POST body rather than in GET query parameters. This is because a large number of keys could previously exceed the maximum URL length, causing errors.

2.12.0 (2018-02-08)

  • [NEW] Index creation APIs and builders including support for text and partial indexes.
  • [NEW] Support for query bookmarks and execution stats.
  • [NEW] Utilities for generating selectors for queries and partial indexes.
  • [IMPROVED] Throw an IllegalArgumentException with a better message if trying to build the client with a null URL instead of a NullPointerException.

    • com.cloudant.client.api.model.Index
    • com.cloudant.client.api.model.IndexField
    • com.cloudant.client.api.Database.createIndex(java.lang.String, java.lang.String, java.lang.String, com.cloudant.client.api.model.IndexField[])
    • com.cloudant.client.api.Database.listIndices

  • [NEW] Added an extra bluemix method to the client builder allowing a custom service name to be used with the VCAP_SERVICES environment variable content.
  • [FIXED] An issue where Changes.hasNext() never returns on receipt of last_seq for continuous changes feeds.

2.10.0 (2017-11-07)

  • [NEW] Added API for upcoming IBM Cloud Identity and Access Management support for Cloudant on IBM Cloud. Note: IAM API key support is not yet enabled in the service.

  • [IMPROVED] Added Row#getError and AllDocsResponse#getErrors for returning any error messages from a view or _all_docs request.
  • [FIXED] Connection leaks in some session renewal error scenarios.
  • [FIXED] IllegalStateException now correctly thrown for additional case of calling MultipleRequestBuilder#build() before add() was called.
  • [UPGRADED] Optional OkHttp dependency to version 3.8.1.
  • [DEPRECATED] The dbCopy setter and getter on the MapReduce class.

2.9.0 (2017-04-26)

  • [NEW] Add faceted search variable argument to drillDown method allowing multiple drill down values to be specified for a single field name.

  • [IMPROVED] Faster shutdown when using the optional OkHttp client.
  • [IMPROVED] Add URL to CouchDbException exception message (where applicable) for easier debugging.
  • [FIXED] Issue with "+" (plus) not being regarded as a reserved character in URI path components.
  • [FIXED] Issue with double encoding of restricted URL characters in credentials when using ClientBuilder.url().

2.7.0 (2016-11-21)

  • [UPGRADED] Optional okhttp dependency to version 3.4.2.
  • [FIXED] NullPointerException when calling AllDocsResponse.getIdsAndRevs for a request with multiple non-existent keys (IDs).
  • [IMPROVED] Preserved path elements from URLs used to construct a ClientBuilder. This allows, for example, a CloudantClientconnection to use a gateway with a URL like https://testproxy.example.net:443/cloudant/mydb.
  • [FIXED] Issue where DesignDocumentManager did not close a FileInputStream.

2.6.2 (2016-09-20)

  • [FIX] NoClassDefFoundError: com.squareup.okhttp.Authenticator for version 2.6.1 if the optional okhttp dependency was not included.

2.5.1 (2016-07-19)

  • [IMPROVED] Made the 429 response code backoff optional and configurable. To enable the backoff add an instance of a Replay429Interceptor with the desired number of retries and initial backoff: ClientBuilder.account("example").interceptors(new Replay429Interceptor(retries, initialBackoff)) A default instance is available using 3 retries and starting with a 250 ms backoff: Replay429Interceptor.WITH_DEFAULTS. To replicate the backoff of version 2.5.0 create an instance using new Replay429Interceptor(10, 250l).

  • [FIX] PreconditionFailedException was never thrown when calling createDB("dbname") when the database already existed.
  • [FIX] Documentation that suggested calling database("dbname", false) would immediately throw a NoDocumentException if the database did not exist. The exception is not thrown until the first operation on the Database instance.
  • [FIX] ClassCastException when the server responded 403 with a null reason in the JSON.

2.4.3 (2016-05-05)

  • [IMPROVED] Reduced the length of the User-Agent header string.
  • [IMPROVED] Use a more efficient HEAD request for getting revision information when using DesignDocumentManager.remove(String id).
  • [FIX] Regression where _design/ was not optional in ID when using DesignDocumentManager methods.
  • [FIX] Issue where use_index was specified as an array instead of a string when only a design document name was provided.
  • [FIX] Issue where empty array was passed for use_index option when FindByIndexOptions.useIndex() was not used.
  • [FIX] Incorrect method names in overview documentation example for connecting to Cloudant service.

2.4.2 (2016-04-07)

  • [FIX] Issue where a java.net.ProtocolException was thrown if the cookie had expired when a request that included a body was sent. Note that the client no longer uses the Expect:100-continue header on requests.
  • [FIX] Fix issue where design documents would not be updated if only the indexes field was updated.
  • [FIX] The equals and hashcode methods for Document and ReplicatorDocument failed to compare revision identifier and some other fields.
  • [FIX] Issue where connections could leak because streams were not closed.
  • [DEPRECATED] The InputStream setters HttpConnection.setRequestBody(InputStream) and HttpConnection.setRequestBody(InputStream, long). Use of the new InputStreamGenerator is preferred because it allows for request replays.
  • [CHANGE] Moved HTTP and interceptor code into a separate jar.

2.3.0 (2016-02-12)

  • [NEW] Constructor for Database subclasses.
  • [IMPROVED] Documentation for Database.findByIndex to show complete selector.

2.1.0 (2015-12-04)

  • [IMPROVED] Included error and reason information in message from CouchDbException classes.
  • [IMPROVED] Added HTTP status code to Response objects.
  • [IMPROVED] Added parameter pagination option for views. See ViewRequest.getResponse(String).
  • [FIX] Too many bytes written exception caused by inconsistent encoding between UTF-8 and the JVM default. UTF-8 is now correctly used for the request body content length and throughout.
  • [FIX] Fixed deserialization of ReplicatorDocument where the source or target url is a JSON object not a string.
  • [FIX] Renew cookies when the server returns a 403 status code with {"error":"credentials_expired"}.
  • [FIX] Cookie authentication now honours custom SSL configurations when making the _session request.

2.0.0 (2015-11-12)

  • [NEW] DesignDocument.MapReduce now has a setter for the dbcopy field.
  • [NEW] Requests for the _all_docs endpoint are made via Database#getAllDocsRequestBuilder() instead of using a view.
  • [NEW] Introduced new view query API. More information is available in the javadoc, including usage and migration examples. Note the absence of an equivalent for queryForStream(). If you were using the queryForStream() method we would be interested in feedback about your use case. For example, if you were using the InputStream directly for streaming API parsing with an alternative JSON library we might be able to make this easier by handling the streams and providing a callback.
  • [NEW] Optional OkHttp dependency for per CloudantClient instance connection pooling.
  • [BREAKING CHANGE] Removed Database.batch(Object) method. Using batch=ok is not recommended.
  • [BREAKING CHANGE] JVM http.maxConnections configured pool is used by default for connection pooling.
  • [BREAKING CHANGE] Removed Apache HttpClient dependency. API methods that used HttpClient classes (e.g. executeRequest) now use HttpConnection instead.
  • [BREAKING CHANGE] CloudantClient public constructors and ConnectionOptions have been removed. CloudantClient instances are now created and have options configured using ClientBuilder.
  • [BREAKING CHANGE] Removed these deprecated methods:
    • CloudantClient.deleteDB(String, String) use CloudantClient.deleteDb(String),
    • Database.invokeUpdateHandler(String, String, String) use Database.invokeUpdateHandler(String, String, Params),
    • CloudantClient.setGsonBuilder(GsonBuilder) use ClientBuilder.gsonBuilder(GsonBuilder).
  • [BREAKING CHANGE] Removed version 1.x view query API.
  • [BREAKING CHANGE] LightCouch classes moved to package com.cloudant.client.org.lightcouch. This should only have a visible impact for CouchDbException and its subclasses.
  • [BREAKING CHANGE] Removed DbDesign class and replaced with DesignDocumentManager. If you were using the getFromDesk method, convert your design document directory to javascript files and use DesignDocumentManager.fromFile(File) or DesignDocumentManager.fromDirectory(File). More information is available in the javadoc, including usage for de-serializing design document javascript files to DesignDocument objects.
  • [FIX] Use the default port for the protocol when a client instance is created from a URL without specifying a port.

1.2.3 (2015-10-14)

1.1.0 (2015-07-31)

  • [BREAKING CHANGE] Hostname verification and certificate chain validation are now enabled by default. To disable these additional checks when the client connects to the database, setSSLAuthenticationDisabled(true) can be called on the ConnectOptions object before you pass it to the CloudantClient constructor.
  • [NEW] New API for specifying the SSLSocketFactory. This can used to enhance security in specific environments. To set this SSLSocketFactory, call the setAuthenticatedModeSSLSocketFactory method on the ConnectOptions object before you pass it to the CloudantClient constructor.
