Exception thrown when trying to empty list of registered attachments #3

Closed Sil68 closed 7 years ago

Sil68 commented 7 years ago

I'm trying to create a groovy-based pre-processor (JSR223PreProcessor) for *Custom SOAP Sampler plugin, which is intended to cover to following tasks:

After some quite extensive research on the net--I'm completely new to whole groovy, java, jmeter topic--, I managed to assemble the groovy script shown below.

    // read data from csv input file
    ArrayList recLst = new ArrayList();
    String fldsep = vars.get("fldsep");
    String fldhd = vars.get("fldhd");

    new File(vars.get("indat")).eachLine('UTF-8') {
        if ((it != null) && (fldhd != null) && (!it.trim().equals(fldhd.trim()))) {
            recLst.add(it.trim());
        } // if
    } // File.eachLine

    // extract relevant parts and feed into Custom SOAP Sampler (registered attachments)
    // csv format:  TMSTMP;PRODID;TENID;FNAM;MDAT
    if (recLst.size() > 0) {
        // empty current attachment list
        ArrayList oldAtts = ctx.getCurrentSampler().getAttachments();

        if (oldAtts.size() > 0) {
            for (attDef in oldAtts) {
                attDef.attachment = null; 
                attDef.contentID = null;
                attDef.contentType = null;
                attDef.type = null;
            } // for
        } // if

        // create new attachment list
        ArrayList newAtts = new ArrayList();

        for (rec in recLst) {
            String[] flds = rec.split(fldsep);

            def attDef = ctx.getCurrentSampler().getAttachmentDefinition();
            attDef.attachment = new File(flds[3]); 
            attDef.contentID = "flds[0]"; 
            attDef.contentType = "application/pdf"; // one of selections from the dropdown (no PDF listed there)
            attDef.type = 1;                        // 1 = resource, 2 = variable

            newAtts.add(attDef);
        } // for

        if (newAtts.size() > 0) {
            ctx.getCurrentSampler().setAttachments(newAtts);
        } // if
    } // if

In a previous post I was faced with an issue with BlazeMeter's step-by-step-debugger plugin, which I resolved by not using it. Now another challenge popped into existence.

Executing the test plan results in an error message, reading

    Unable to update attachment references, see log files for details.

Having a peek into the jmeter.log file reveals

Apparently the approach taken to empty the list of currently registered attachments is leading to this kind of error, which now is begging the question as how to implement this is a correct fashion (where are these NUL entries coming from, which are making up apprximately 95% of the whole log file?).

One tackled, another one to go..

My setup comprises:

Sample input csv file

    TMSTMP;PRODID;TENID;FNAM;MDAT
    '20170406112044044970077';'PROD01';'TENANT03';'/media/sf_Projects/tstprj/archive/tstdoc/tstdoc-00000.pdf';'<?xml version=1.0 encoding=UTF-8?><tstpfx:metainformation xmlns:tstpfx=http://my.host.local/tstprj/metainformation_v2.xsd id=000000069496>meta data #01</tstpfx:metainformation>
    '
    '20170406112047030620037';'PROD02';'TENANT01';'/media/sf_Projects/tstprj/archive/tstdoc/tstdoc-00001.pdf';'<?xml version=1.0 encoding=UTF-8?><tstpfx:metainformation xmlns:tstpfx=http://my.host.local/tstprj/metainformation_v2.xsd id=000000069496>meta data #02</tstpfx:metainformation>
    '

This file is getting read twice: (1) by the JSR223 pre-processor to build the attachment list; (2) by the Custom SOAP Sampler, which subsequently iterates over each entry of this file, and passes the relevant bits & bobs to the SOAP Envelop

    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tstprj="http://my.host.local/">
       <soapenv:Header/>
       <soapenv:Body>
          <tstprj:archive>
             <product>${PRODID}</product>
             <tenant>${TENID}</tenant>
             <filename>${FNAM}</filename>
             <metadata>${MDAT}</metadata>
             <content>cid:${TMSTMP}</content>
          </tstprj:archive>
       </soapenv:Body>
    </soapenv:Envelope>

Like I commented in previous your issue the way of cleaning attachments by setting attachment properties to NULL - is incorrect. Try first what happens if you comment out cleaning logic and go straight to attachment setting.

Another thing is that although on the list of attachment content-type the choice is limited, you can still put any content-type you like. Both in UI by typing the desired value, or programmatically.
