[Zoo-discuss] Length of Output filename and service completion

[Fenoy Gerald]

Dear Rakesh,
sorry for late reply.

After some testing, I cannot reproduce the issue locally.

I have the following defined in the main section of the main.cfg file:

tmpPath=/tmp/
tmpUrl = http://localhost/mpPathRelativeToServerAdress/

Using the following source for the HelloPy service:

import zoo

def HelloPy(conf,inputs,outputs):
        outputs["Result"]["generated_file"]=conf["main"]["tmpPath"]+"S2_NDVI_USING_FTEP_B4_B8_20160629_1234567"+conf["lenv"]["usid"]+".tif"
        f=open(outputs["Result"]["generated_file"],"wb")
        f.write(bytearray(512))
        f.close()
        return zoo.SERVICE_SUCCEEDED

Running Execute request never failed. You have noticed that the name is even longer than the one you used.

I would like to have more details about your setup and the value you have set in outputFilename, does this last contain the tmpPath as expected ?

I hope to hear back from you and we can solve this issue.

Best regards,

The GetStatus is always returning status as "Running" even though the processing is completed and returns with integer 3 (success) and GetResult file is generated. This does not happen always and it happens only certain times. My observation after several testing is that the length of output file name affects the behaviour of service completion.
