17.06 - check not respond with Force parameter

[PhilGourgand]

Hi,
On my ubuntu server, I installed MediaConch cli 17.06 for ubuntu
but on my local machine (macos), I got MediaConch cli 17.05 installed with brew

I got noticed a weird behavior on the last version 17.06 for ubuntu with my command :

mediaconch --Policy=Mediaconch_MXF_PAD.xml --Format=xml --Force /Test_file.mxf

This command works well on local macos MediaConch cli 17.05
but on MediaConch cli 17.06 I have to ask twice to get a report

Behavior :

• First time nothing Mediaconch doesn’t respond
• Second time, I got the report

On Local files, distant files (HTTP/S & S3)

But when I remove the —Force parameter, media conch answer every request, but if I change anything on the policy
The report is not refresh

Exemple:

ubuntu@:~/Checker$ mediaconch --Policy=Mediaconch_MXF_PAD.xml --Format=xml --Force https://s3-eu-west-1.amazonaws.com/test_bucket/Bande_Demo.mxf

ubuntu@:~/Checker$ mediaconch --Policy=Mediaconch_MXF_PAD.xml --Format=xml --Force https://s3-eu-west-1.amazonaws.com/test_bucket/Bande_Demo.mxf

Wow, several issues in one shot :(.

--force is expected to be used only for forcing again the analysis of a file after e.g. bug fixed in the tool. Policy timestamp change should be caught a cache cleared in that case. We need to fix that.

I need to try to reproduce the issue for the main issue, it is not expected.

@g-maxime can you reproduce the issue in our environment?

[g-maxime]

@JeromeMartinez Same output, mediaconch return an empty line one time on two (Ubuntu Server 16.04)

user@ubuntu:~$ mediaconch --Force Standards_Mismatch.mkv
pass! Standards_Mismatch.mkv

user@ubuntu:~$ mediaconch --Force Standards_Mismatch.mkv

user@ubuntu:~$ mediaconch --Force Standards_Mismatch.mkv
pass! Standards_Mismatch.mkv

user@ubuntu:~$ mediaconch --Force Standards_Mismatch.mkv

user@ubuntu:~$ mediaconch --Force Standards_Mismatch.mkv
pass! Standards_Mismatch.mkv

but on MediaConch cli 17.06 I have to ask twice to get a report

This is expected to be fixed, please test latest snapshots (at least 20170803).

but if I change anything on the policy The report is not refresh

We can not reproduce this issue, we see the report refreshed if the policy file has changed (timestamp of the file).
