Re: [basex-talk] Which zip did BaseX choke on?

16 Oct 2015

      db:output certainly looked promising, but I get no output from a try/catch clause, alas:

for $zip in file:list($hm)
return
try {
     db:add("myDB", $hm || '\' || $zip, "", map { 'intparse': true()})
} catch * {
      db:output($zip)
}

Any other thoughts, BaseX users?

I may be wrong, but I think you need to wrap the $err:code in db:output(): see http://docs.basex.org/wiki/XQuery_Update#Returning_Results

Hmm, it is surprisingly hard to get some useful logging information out of this.

Here for example I fall foul of a XQuery syntax here: “all expressions must be updating or return an empty sequence. ”

for $zip in file:list($hm)
return  try {
                    db:add("myDB", $hm || '\' || $zip, "", map { 'intparse': true() })
                } catch * {
                    $err:code
                }

Can anyone help me rephrase this so when BaseX halts on a bad zipfile, I at least know what the name of the zipfile is?

Have you tried using try/catch?

for zip in zips return try { unzip() } catch ...

I love BaseX for the simplicity it brings to XML handling. But this is a problem I have not encountered before.

I am creating a DB from about 17,000 small zipfiles, each containing a directory structure and somewhere within each, some XML. BaseX chokes on one of these files giving the error:  “invalid entry size (expected 0 but got 11083 bytes)”.

So clearly one or more of the zips is invalid -  but which one(s)?

Is there any way that BaseX can echo to me the file that is causing the error? DEBUG is set to TRUE, but I don’t get any morer verbose output. I am using the GUI, and running a BSX script too.

Thanks in advance,
C.
