Denis N. Antonioli closed WT-87:
--------------------------------

    Resolution: Won't Fix

Test runs with the attached spike have shown no improvements with regard to the memory behaviour.

> Addressing the OutOfMemory issue in reporting
> ---------------------------------------------
>
>          Key: WT-87
>          URL: http://webtest-community.canoo.com/jira/browse/WT-87
>      Project: WebTest
>         Type: Bug
>     Reporter: Denis N. Antonioli
>     Assignee: Denis N. Antonioli
>      Fix For: 1.7
>  Attachments: AllTests.java, XmlReporter.java, XmlReporterTest.java, XmlResultConverter.java, XmlResultConverterTest.java
>
> From previous discussions and analyses, it looks like the xml reporting is one of the main culprit.
> xml reporting works now as follows:
> (1) reads the existing report file and build a DOM for it,
> (2) convert the testResult (all the java Objects for the steps) into xml Element and inserts them at the end of the DOM,
> (3) serializes the DOM back to the report file.
> I see two issues with this procedures:
> First, it repeatedly reads and converts the report file to DOM, which is a potentially expensive process, and it needs every time more memory since the report file itself is growing.
> Then, it converts the testResult from hierarchy of webtest Objects to a DOM, which is also bound to consume memory.
> I'm planning to addess the two issues separately.
> First, I'd like to get rid of the reading/writing of the result file. I've already done a prototyp that works as follow:
> the webtest report xml file is just a container:
> In this example, the user set the name of the webtest report file to WebTestReport.xml in the test configuration.
> The file WebTestReport.xml contains just:
> <?xml version="1.0" encoding="ISO-8859-1"?>
> <!DOCTYPE summary [
> <!ENTITY testresult SYSTEM "WebTestReport_.xml" >
> ]>
> <summary>
> &testresult;
> </summary>
> The file WebTestReport_.xml contains a concatenation of all the <testResult>.
> By doing it this way, no changes are required from all the xml processors/xsl stylesheet used to format the reports works.
> Then I will suppress the intermediate DOM and serialize the Webtest objects directly to the output file as xml tags.
> What do you think?
> Good idea? Bad idea? Other proposal? Any pitfall?
> I'm hoping for comments ;-)
