AddFile getting stuck

Natasha

Hi All,

We have encountered a very strange issue in the workflow we are using to submit the files. The following is the brief description of the workflow :-
select 100 html files, click on submit, files get attached to the workflow, next task is to look for the DCRs associated with the HTML files and add these DCRs to the workflow.
The problem is that it is getting stuck at attaching the DCRs to the workflow.
Is there any limitation on the number of files that can be added to the workflow?

Would appreciate if someone can provide the answer at the earliest?

Thanks,
Natasha.

you should post the platform and version, and also HOW you are attaching files - I mean which command. Try to add them in a loop instead of using
add multiple files in one go.

I never had issues with this kind of task, that is trivial

Hi ,

I don't think you have restriction in the number of files you select.
Pls check the way how you are getting the selected files and passing it to the task.
Can you please share the screenshot of the error.

Besides what's already been posted in response - are you sure that the problem is happening when you're trying to attach the DCRs? Or could it be happening after you attach the DCRs and try to transition to another task?
If you're sure it's happening when you're trying to attach the DCRs - take a look at the output of iwgetwfobj taskid for the task that does this - and see if there's something there like "tryingtolock="t" or "waitingforlock="t"?

The potential issues I see in the code above are:

dbg("RETURN EAS: " . scalar(keys %attrib_hash)); #=# return %attrib_hash;}After the code seems to fail (or after it succeeds) - check IWHOME/tmp/debug.log

 return %attrib_hash;

I could not see any blatant errors, so this *should* work - probably there is something really simple that breaks the code. As ghoti has suggested - try to debug the code by printing to a log file.

Thanks everyone who spared time and looked into the code. I had the put the log statements as suggested and found that the code for extracting EAs is working fine. The only thing I noticed which was not letting the task to transition onto next task is the comment parameter of the callback method.
We were passing the comment as


$message = "Attached $num_files DCR's:\n".$file_list;
where $file_list is the list containing the names of the all the DCRs

We were submitting some 1000 odd files which includes gif,jpg,js,html, finding out the associated DCRs with these HTMLs through the code posted earlier, adding those 200 DCRs to the job and to the comment as well. This was creating the problem and not letting it to transition.
So certainly there is a limitation on the comment that we can put in the callback method.
Could anyone point out what exactly is the limit?
Thanks for you help so far

Natasha.

don't remember outta top of my head, but something really small.

I wrote a truncComment function, due to this very issue that you reporting. I cut down to 4096 bytes.
