eXist-db 5.0.0

v5.0.0 - September 2nd, 2019

We are very happy to announce that eXist-db 5.0.0 has been released.

eXist-db 5 represents a substantial development effort, incorporating more than 1,400 commits from 26 contributors over the course of two and a half years.

The most significant improvements to this version of eXist-db involve collection and document locking. The focus of this effort firstly was to ensure "correctness" (i.e., to prevent database corruption) and secondly to improve concurrent performance (i.e., performance when many users are accessing the database) and reporting on the state of the system to aid developers and system administrators in diagnosing locking issues. These and other improvements detailed below aim to dramatically boost eXist-db's reliability and stability.

Other highlights of this release include that eXist-db has a new faceted browsing facility, supports more standard XQuery 3.1 functions, and is now built using Maven and is available via DockerHub. Read more about these and all of the improvements below. Be sure to read to the end for important notes about upgrading.

New Build System

The build system for eXist-db was previously Apache Ant. With 5.x.x we have completed a full migration of the build system to Apache Maven. Maven affords us a much more modular, rigorous, and flexible process, whilst reducing the maintenance burden that we experienced with Ant. We are now also able to easily publish artifacts to Maven Central for those eXist-db users that embed eXist-db within their own applications.

One major change, is that eXist-db can no longer be built "in-place" from a Git clone, instead building eXist-db now generates a distribution. It is recommended that all users working with the source code, should start with a fresh clone of eXist-db 5.0.0, as its source footprint is not compatible with 5.0.0-RC7 or older.

The Building eXist-db documentation page has been updated with the latest instructions for building eXist-db with Maven.

Backwards Compatibility

eXist-db 5.0.0 is binary compatible with eXist-db RC8, RC7, and RC6. Regardless, before upgrading to this version of eXist-db, it is strongly recommended to perform a full backup and restore. Users who are upgrading should always consult the Upgrading Guide in the documentation. For details of backwards compatibility with versions of eXist-db prior to 5.0.0-RC6, please see the Backwards Compatibility details of 5.0.0-RC6.

  • NOTE: Applications that shipped with previous version of eXist-db are not guaranteed to be forwards compatible. To ensure smooth operation you should clear your web browser's cache before trying to access newer apps.

Downloading this Version

  • eXist-db v5.0.0 is available for download from Bintray.
  • Docker images for are available from eXist-db's DockerHub.
  • Maven artifacts are available from Maven Central.
  • Mac users of the Homebrew package repository may acquire eXist 5.0.0 directly from there via. the exist-db cask.

High Scores!

We would like to say a big Thank You to all of those developers who contributed to eXist-db 5.0.0. Your contributions were very welcome.

New Build System

The build system for eXist-db was previously Apache Ant. With 5.x.x we have completed a full migration of the build system to Apache Maven. Maven affords us a much more modular, rigorous, and flexible process, whilst reducing the maintenance burden that we experienced with Ant. We are now also able to easily publish artifacts to Maven Central for those eXist-db users that embed eXist-db within their own applications.

One major change, is that eXist-db can no longer be built "in-place" from a Git clone, instead building eXist-db now generates a distribution. It is recommended that all users working with the source code, should start with a fresh clone of eXist-db 5.0.0, as its source footprint is not compatible with 5.0.0-RC7 or older.

The Building eXist-db documentation page has been updated with the latest instructions for building eXist-db with Maven.

Backwards Compatibility

eXist-db 5.0.0 is binary compatible with eXist-db RC8, RC7, and RC6. Regardless, before upgrading to this version of eXist-db, it is strongly recommended to perform a full backup and restore. Users who are upgrading should always consult the Upgrading Guide in the documentation. For details of backwards compatibility with versions of eXist-db prior to 5.0.0-RC6, please see the Backwards Compatibility details of 5.0.0-RC6.

  • NOTE: EXPath Apps shipped with previous version of eXist-db, are not guaranteed to be forwards compatible. To ensure smooth operation you should clear your Web-Browsers cache before trying to access newer apps.

Downloading this Version

  • eXist-db v5.0.0 is available for download from Bintray.
  • Docker images for are available from eXist-db's DockerHub.
  • Maven artifacts are available from Maven Central.
  • Mac users of the Homebrew package repository may acquire eXist 5.0.0 directly from there via. the exist-db cask.

High Scores!

We would like to say a big Thank You to all of those developers who contributed to eXist-db 5.0.0. Your contributions were very welcome.

eXist-db 4.7.0

v4.7.0 - May 19, 2019

This release closes a major memory leak introduced in 4.6.0, removes a deadlock condition and fixes a number of bugs.

Features

  • Update to Tika version 1.20 for content extraction module and fix some related bugs
  • Add in-memory buffer to solve performance issue accessing remote eXist via XML:DB API
  • Update EXQuery RESTXQ to 0.1.34, fixes parsing issues with Accept and Content-Type HTTP headers

Bug Fixes

  • XML serializer leaking memory
  • Fix deadlock: memory size from the collection does not need a READ_LOCK, it is an estimate anyway
  • Test suite was not correctly reporting failing tests
  • Fix ByteArrayPool and CharArrayPool memory leaks
  • Fix problems with computed namespace construction
  • When loading XQuery modules dynamically, declared global variables were not analyzed properly
  • Switch out org.exist.util.hashtable implementation for FastUtil. eXist's implementations have problems with hash-collisions and chaining
  • Allow for passing options for ft:search queries. This allows to perform leading-wildcard queries on computed index fields
  • Fix arrow operator and higher order functions: context sequence passed incorrectly
  • Fix broken XQuery Update for 'insert following'
  • Fix ArrayOutOfBoundsException querying doc with enclosed expression and fn:id function
  • Fix EXPath HTTP Client - Previously when override-media-type was set and a charset was specified, the charset was ignored
  • Fix an issue introduced by PR #2367: a lucene index configured with a match attribute should only be created for nodes matching the path, not all descendant nodes

Backwards Compatibility

eXist-db 4.7.0 is binary compatible with the 4.6.1 and 4.6.0 versions of eXist-db. Users who are upgrading should always consult the Upgrading Guide in the documentation.

Downloading this Version

  • eXist-db v4.7.0 is available for download from Bintray.
  • Docker images for are available from eXist-db's DockerHub.
  • Maven artifacts are available from our mvn-repo.
  • Mac users of the Homebrew package repository may acquire eXist 4.7.0 directly from there via. the exist-db cask.

eXist-db 5.0.0 RC7

v5.0.0-RC7 - March 2, 2019

eXist-db 5.0.0-RC7 is a hotfix release. Unfortunately the code restructuring performed in v5.0.0-RC6 caused failures in the Java Service Wrapper. This will especially impact Windows users, who typically start and stop eXist-db as a service. Using a service is the only way on Windows to ensure eXist-db is properly stopped on system shutdown. We thus consider this critical and published a hotfix.

Bug Fixes

  • fix classpath for yajsw Java service wrapper
  • fix jnlp webstart for Java admin client
  • fix test failures depending on github location
  • small fix to util:log functions to output string values without leading and closing quote
