eXo JCR 1.7 released

– The one of the main purpose of this release is improvement of core part of JCR implementation to make it more reliable in multi user, high concurrent environment
with big arrays of data. eXo JCR was highly stress tested using dedicated multi-benchmarking framework as well as third party test tools using different
size of data storage (to 12M documents of different size).
– To make it possible move big amount of data between repositories as well as performing backup/restore, XML export/import was improved with XML streaming,
a.k.a. StAX based engine
– Several important proprietary features were added such as: random IO for BLOBS (extremelly useful for the FTP and CIFS transport), IPv6 support for replication and others
(see details below)
– Two new Value Storage implementations were added: (1) another type of local FS based called TreeFileValueStorage is better than Simple one for managing big
amount of documents (it is faster for file searching operations). (2) Amazon S3 based value storage allows storing documents remotely using REST based protocol
– JCR WebDAV server was refactored, now it uses eXo REST framework underneath, MS Office and Open Office plugins were improved as well
– JCR CIFS was significantly improved and fixed, now it supports NT LN 0.12 protocol, plain text and challange/response authentication, random IO and other important features

* locking mechanism was updated. Now it contains valid timeout value;
* implemented chunked transfer-encoding;
* refactored properties working in PROPFIND, REPORT, PROPPATCH commands;
* PROPNAMES type of the PROPFIND included

Microsoft Office Plugin Release updates

* exo_jcr.msofficeplugin.common library created;
* proxy settings was removed from Settings dialog;
* small redesigning of the dialogs windows;

Open Office Add-On release updates

CIFS Service changes
– NTLM 0.12 protocol dialect impementation added.NTLM 0.12 dialect is the newest of standart dialects.
– VirtualCircuits added – client-server session stability increased.
– java-implemented transport layer (NetBIOS) added. Server runs on nonWindoes systems now.
– user authentication implemented. Plain text and challange/response mechanism.
– file random write ability added. Just a small files (size <50Mb). File size limitation depends from common server and network productivity.
– server configuration updated.

Restrictions, defects, detected faults:
– file write restriction – server can’t write large files. Server haven’t time to finish file save. File size limitation depends from common server and network productivity.
– when server runs over nonWindows systems it’s invisible in Microsoft Windows Neighbourhood.
– representation of and oparations over samename files are uncleare.
– if negotiated dialect is LanMan, there are faults with enters on server (enters from 2-3 attempt).
– if you have SVN installed on client, there may by shorttime hangs of clients whan you performs any operation in root folders.
