Apache Chemistry Goes TLP
<p>Just a few days ago <a href="http://chemistry.apache.org/" target="_self">Apache Chemistry</a> <a href="https://blogs.apache.org/foundation/entry/the_apache_software_foundation_announces11" target="_self">became a top-level project</a> (TLP) of the Apache Software Foundation (ASF). As a reminder, Chemistry provides client libraries implementing the <a href="http://docs.oasis-open.org/cmis/CMIS/v1.0/cmis-spec-v1.0.html" target="_self">CMIS</a> spec in Java, Python, PHP and .NET, and a server-oriented library for Java. Learn more about this on the <a href="http://chemistry.apache.org/" target="_self">Chemistry page</a>.</p>

<p>A question we often get is "Is Nuxeo Java EE compliant? Does it run in my preferred application server?".</p>
Continue ReadingWhy Nuxeo Dropped JCR
<p>There have been questions about JCR vs CMIS recently (<a href="http://www.cmswire.com/cms/web-cms/is-jcr-dead-009676.php" target="_self">Is JCR Dead?</a>), and I thought I'd expand a bit on why we at Nuxeo decided to drop support for JCR.</p>

<p><a href="http://na.apachecon.com/c/acna2010/" target="_self">ApacheCon 2010</a> starts next week in Atlanta, and if you want to know more about the <a href="http://www.oasis-open.org/committees/cmis" target="_self">CMIS</a> standard from <a href="http://www.oasis-open.org/" target="_self">OASIS</a>, <a href="http://incubator.apache.org/chemistry/index.html" target="_self">Apache Chemistry</a>, and <a href="http://incubator.apache.org/chemistry/opencmis.html" target="_self">OpenCMIS</a> then you should come! On Wednesday, Nov 3 (at 2pm) I'll be presenting a talk on these topics. Here's the abstract:</p>

<p>Last week a meeting took place in Munich between the main developers behind the two Java <a href="http://incubator.apache.org/chemistry/">Chemistry</a> projects (Chemistry and OpenCMIS). I can say that the meeting was a success and that the two codebases are now in the process of actively being merged!</p>

<p>The upcoming <a href="http://www.oasis-open.org/committees/cmis">CMIS</a> standard is approaching its final 1.0 version, and I thought I would take the time to present some of its most advanced features.</p>
Continue ReadingThe Promises of Modern Chemistry
<p> By now, most of you should have heard about <a href="http://www.oasis-open.org/committees/cmis/">CMIS</a>, the upcoming specification that promises interoperability between many systems for common content management tasks. The CMIS specification is being driven by an OASIS Technical Committee and is currently still a draft; it is expected to be finalized late 2009 or early 2010. </p>

<p> A few weeks ago I gave an <a href="http://www.cmswire.com/cms/enterprise-cms/nuxeos-take-on-apache-cmis-implementation-aka-chemistry-004513.php">interview</a> to Irina Guseva of <a href="http://www.cmswire.com/">CMSWire</a>. We touched the subjects of strategic value of CMIS, Apache Chemistry project history, partnerships, open source, future plans around CMIS, and more. </p>
Continue ReadingWhat's the point of JCR?
<p> Nuxeo is switching its <a href="/products/content-management-platform/">ECM</a> to Java, and we're using <a href="http://jcp.org/en/jsr/detail?id=170">JCR</a> for our document storage. JCR (Java Content Repository, standardized by <a href="http://jcp.org/en/jsr/detail?id=170">JSR-170</a> and the upcoming <a href="http://jcp.org/en/jsr/detail?id=283">JSR-283</a>) is a young specification with a promising future — but what's its point, you may ask, as all existing content management systems are already storing content very well without it? Its goal is <em>interoperability</em> between vendors, which will make it possible for people who write applications needing to store content to have a unified API for such manipulations. All major content repository vendors are active in the JSR-283 expert group, and all are working on JCR bindings for their various proprietary repositories. </p>
Continue ReadingGenericSetup for CPS, CMF and Zope
<p> GenericSetup is a framework to describe the configuration of a Zope site as a set of XML files (and sometimes other associated files). It can import profiles, which may create objects or change their configuration, and export profiles, which makes a snapshot of the configuration and writes it to a set of XML files. </p>

<p> This bug day was announced on short notice, we we still managed to kill 26 bugs (while 9 new were opened). That's good work! </p>

Continue ReadingCPS Bug Day Wrapup
<p> The CPS bug day this Wednesday was quite productive. A number of actual bugs were fixed, but more importantly a lot of bug triage and sorting happened, to determine what was urgent (going into CPS 3.3.6), what was necessary for the next stable CPS 3.4 release, and what could be postponed to a later development cycle (CPS 3.5). The <a href="http://svn.nuxeo.org/trac/pub/timeline?from=09%2F14%2F05&daysback=0&ticket=on">Timeline for Wednesday</a> show 65 bugs resolved (fixed or closed). In addition to these, several hundreds have been retargetted or cleaned up. </p>
Continue ReadingObject-Relational mapping in Zope
<p> I've been interested in object-relational mapping in Zope for a while. I see this as the keystone of a proper enterprise-grade application server, and I've been investigating existing tools and what can be done with them. Here's a quick rundown. </p>

<p> Chris McDonough has a nice presentation of ZODB, with some tips about how to make it perform better. One I hadn't read about before is the <code>cacheMinimize</code> in the middle of big transactions; I'll have to check how it performs in some situations. </p>

<p> Tiger comes with python 2.3.5 bundled, which is nice, but sometimes you want to recompile it, or you want to add site-packages to it without disturbing the standard OS installation. Here's what I had to do to compile it, and python-ldap with it. </p>
Continue ReadingDeadlockDebugger 1.0
<p>This product adds a hook so that a deadlocked Zope process can be debugged, by dumping a traceback of all running python processes. The dump is sent to the event log (at the DEBUG level) and returned to the browser (even though the Zope is deadlocked and doesn't answer any other requests!).</p>
Continue ReadingCaching is hard
<p>Caching is a difficult problem, especially when needing to correctly invalidate entries. Invalidating is difficult when there may be several caches spread across ZODB connection (this is the case for '_v_' attributes), or spread across ZEO clients. Accessing a '_v_' attribute in another ZODB connection (i.e., usually, a different thread) is not really feasible, and accessing another ZEO client that may be across the world is impossible directly.</p>
