Apache CouchDB CHANGES ====================== Version 0.9.2 ------------- * Remove branch callbacks to allow building couchjs against newer versions of Spidermonkey. * Fix replication with 0.10+ servers initiated by an 0.9 server (COUCHDB-559). Version 0.9.1 ------------- Build and System Integration: * PID file directory is now created by the SysV/BSD daemon scripts. * Fixed the environment variables shown by the configure script. * Fixed the build instructions shown by the configure script. * Updated ownership and permission advice in `README` for better security. Configuration and stats system: * Corrected missing configuration file error message. * Fixed incorrect recording of request time. Database Core: * Document validation for underscore prefixed variables. * Made attachment storage less sparse. * Fixed problems when a database with delayed commits pending is considered idle, and subject to losing changes when shutdown. (COUCHDB-334) External Handlers: * Fix POST requests. Futon Utility Client: * Redirect when loading a deleted view URI from the cookie. HTTP Interface: * Attachment requests respect the "rev" query-string parameter. JavaScript View Server: * Useful JavaScript Error messages. Replication: * Added support for Unicode characters transmitted as UTF-16 surrogate pairs. * URL-encode attachment names when necessary. * Pull specific revisions of an attachment, instead of just the latest one. * Work around a rare chunk-merging problem in ibrowse. * Work with documents containing Unicode characters outside the Basic Multilingual Plane. Version 0.9.0 ------------- Futon Utility Client: * Added pagination to the database listing page. * Implemented attachment uploading from the document page. * Added page that shows the current configuration, and allows modification of option values. * Added a JSON "source view" for document display. * JSON data in view rows is now syntax highlighted. * Removed the use of an iframe for better integration with browser history and bookmarking. * Full database listing in the sidebar has been replaced by a short list of recent databases. * The view editor now allows selection of the view language if there is more than one configured. * Added links to go to the raw view or document URI. * Added status page to display currently running tasks in CouchDB. * JavaScript test suite split into multiple files. * Pagination for reduce views. Design Document Resource Paths: * Added httpd_design_handlers config section. * Moved _view to httpd_design_handlers. * Added ability to render documents as non-JSON content-types with _show and _list functions, which are also httpd_design_handlers. HTTP Interface: * Added client side UUIDs for idempotent document creation * HTTP COPY for documents * Streaming of chunked attachment PUTs to disk * Remove negative count feature * Add include_docs option for view queries * Add multi-key view post for views * Query parameter validation * Use stale=ok to request potentially cached view index * External query handler module for full-text or other indexers. * Etags for attachments, views, shows and lists * Show and list functions for rendering documents and views as developer controlled content-types. * Attachment names may use slashes to allow uploading of nested directories (useful for static web hosting). * Option for a view to run over design documents. * Added newline to JSON responses. Closes bike-shed. Replication: * Using ibrowse. * Checkpoint replications so failures are less expensive. * Automatically retry of failed replications. * Stream attachments in pull-replication. Database Core: * Faster B-tree implementation. * Changed internal JSON term format. * Improvements to Erlang VM interactions under heavy load. * User context and administrator role. * Update validations with design document validation functions. * Document purge functionality. * Ref-counting for database file handles. Build and System Integration: * The `couchdb` script now supports system chainable configuration files. * The Mac OS X daemon script now redirects STDOUT and STDERR like SysV/BSD. * The build and system integration have been improved for portability. * Added COUCHDB_OPTIONS to etc/default/couchdb file. * Remove COUCHDB_INI_FILE and COUCHDB_PID_FILE from etc/default/couchdb file. * Updated `configure.ac` to manually link `libm` for portability. * Updated `configure.ac` to extended default library paths. * Removed inets configuration files. * Added command line test runner. * Created dev target for make. Configuration and stats system: * Separate default and local configuration files. * HTTP interface for configuration changes. * Statistics framework with HTTP query API. Version 0.8.1-incubating ------------------------ Database Core: * Fix for replication problems where the write queues can get backed up if the writes aren't happening fast enough to keep up with the reads. For a large replication, this can exhaust memory and crash, or slow down the machine dramatically. The fix keeps only one document in the write queue at a time. * Fix for databases sometimes incorrectly reporting that they contain 0 documents after compaction. * CouchDB now uses ibrowse instead of inets for its internal HTTP client implementation. This means better replication stability. HTTP Interface: * Fix for chunked responses where chunks were always being split into multiple TCP packets, which caused problems with the test suite under Safari, and in some other cases. * Fix for an invalid JSON response body being returned for some kinds of views. (COUCHDB-84) * Fix for connections not getting closed after rejecting a chunked request. (COUCHDB-55) * CouchDB can now be bound to IPv6 addresses. * The HTTP `Server` header now contains the versions of CouchDB and Erlang. JavaScript View Server: * Sealing of documents has been disabled due to an incompatibility with SpiderMonkey 1.9. * Improve error handling for undefined values emitted by map functions. (COUCHDB-83) Build and System Integration: * The `couchdb` script no longer uses `awk` for configuration checks as this was causing portability problems. * Updated `sudo` example in the `README` to use the `-i` option, this fixes problems when invoking from a directory the `couchdb` user cannot access. Futon Utility Client: * The view selector dropdown should now work in Opera and Internet Explorer even when it includes optgroups for design documents. (COUCHDB-81) Version 0.8.0-incubating ------------------------ Database Core: * The view engine has been completely decoupled from the storage engine. Index data is now stored in separate files, and the format of the main database file has changed. * Databases can now be compacted to reclaim space used for deleted documents and old document revisions. * Support for incremental map/reduce views has been added. * To support map/reduce, the structure of design documents has changed. View values are now JSON objects containing at least a `map` member, and optionally a `reduce` member. * View servers are now identified by name (for example `javascript`) instead of by media type. * Automatically generated document IDs are now based on proper UUID generation using the crypto module. * The field `content-type` in the JSON representation of attachments has been renamed to `content_type` (underscore). HTTP Interface: * CouchDB now uses MochiWeb instead of inets for the HTTP server implementation. Among other things, this means that the extra configuration files needed for inets (such as `couch_httpd.conf`) are no longer used. * The HTTP interface now completely supports the `HEAD` method. (COUCHDB-3) * Improved compliance of `Etag` handling with the HTTP specification. (COUCHDB-13) * Etags are no longer included in responses to document `GET` requests that include query string parameters causing the JSON response to change without the revision or the URI having changed. * The bulk document update API has changed slightly on both the request and the response side. In addition, bulk updates are now atomic. * CouchDB now uses `TCP_NODELAY` to fix performance problems with persistent connections on some platforms due to nagling. * Including a `?descending=false` query string parameter in requests to views no longer raises an error. * Requests to unknown top-level reserved URLs (anything with a leading underscore) now return a `unknown_private_path` error instead of the confusing `illegal_database_name`. * The Temporary view handling now expects a JSON request body, where the JSON is an object with at least a `map` member, and optional `reduce` and `language` members. * Temporary views no longer determine the view server based on the Content-Type header of the `POST` request, but rather by looking for a `language` member in the JSON body of the request. * The status code of responses to `DELETE` requests is now 200 to reflect that that the deletion is performed synchronously. JavaScript View Server: * SpiderMonkey is no longer included with CouchDB, but rather treated as a normal external dependency. A simple C program (`_couchjs`) is provided that links against an existing SpiderMonkey installation and uses the interpreter embedding API. * View functions using the default JavaScript view server can now do logging using the global `log(message)` function. Log messages are directed into the CouchDB log at `INFO` level. (COUCHDB-59) * The global `map(key, value)` function made available to view code has been renamed to `emit(key, value)`. * Fixed handling of exceptions raised by view functions. Build and System Integration: * CouchDB can automatically respawn following a server crash. * Database server no longer refuses to start with a stale PID file. * System logrotate configuration provided. * Improved handling of ICU shared libraries. * The `couchdb` script now automatically enables SMP support in Erlang. * The `couchdb` and `couchjs` scripts have been improved for portability. * The build and system integration have been improved for portability. Futon Utility Client: * When adding a field to a document, Futon now just adds a field with an autogenerated name instead of prompting for the name with a dialog. The name is automatically put into edit mode so that it can be changed immediately. * Fields are now sorted alphabetically by name when a document is displayed. * Futon can be used to create and update permanent views. * The maximum number of rows to display per page on the database page can now be adjusted. * Futon now uses the XMLHTTPRequest API asynchronously to communicate with the CouchDB HTTP server, so that most operations no longer block the browser. * View results sorting can now be switched between ascending and descending by clicking on the `Key` column header. * Fixed a bug where documents that contained a `@` character could not be viewed. (COUCHDB-12) * The database page now provides a `Compact` button to trigger database compaction. (COUCHDB-38) * Fixed portential double encoding of document IDs and other URI segments in many instances. (COUCHDB-39) * Improved display of attachments. * The JavaScript Shell has been removed due to unresolved licensing issues.
