That dramatically improves readability of multi-line + strings. + * Same goes for editing of JSON string values. When a change to a field value is + submitted, and the value is not valid JSON it is assumed to be a string. This + improves editing of multi-line strings a lot. + * Hitting tab in textareas no longer moves focus to the next form field, but simply + inserts a tab character at the current caret position. + * Fixed some font declarations. + +Build and System Integration: + + * Updated and improved source documentation. + * Fixed distribution preparation for building on Mac OS X. + * Added support for building a Windows installer as part of 'make dist'. + * Bug fix for building couch.app's module list. + * ETap tests are now run during make distcheck.

More info can be found at + http://ci.apache.org/buildbot.html + +Version 0.10.1 +-------------- + +Replicator: + + * Stability enhancements regarding redirects, timeouts, OAuth. + +Query Server: + + * Avoid process leaks + * Allow list and view to span languages + +Stats: + + * Eliminate new process flood on system wake + +Build and System Integration: + + * Test suite now works with the distcheck target. + +Version 0.10.0 +-------------- + +Storage Format: + + * Add move headers with checksums to the end of database files for extra robust + storage and faster storage. + +View Server: + + * Added native Erlang views for high-performance applications. + +HTTP Interface: + + * Added optional cookie-based authentication handler. + * Added optional two-legged OAuth authentication handler. + +Build and System Integration: + + * Changed `couchdb` script configuration options. + * Added default.d and local.d configuration directories to load sequence. + + +Version 0.9.2 +------------- + +Replication: + + * Fix replication with 0.10 servers initiated by an 0.9 server (COUCHDB-559). + +Build and System Integration: + + * Remove branch callbacks to allow building couchjs against newer versions of + Spidermonkey. + +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: + + * 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 `README` to use the `-i` option, this fixes + problems when invoking from a directory the `couchdb` user cannot access. + +Futon: + + * 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: + + * 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. |
