Wrong Fits type recognition, soffice blocking and Sidekik congestion

[ghost]

Descriptive summary

We report this problem only for the benefit of other users because it is not an internal problem for Hyrax but a dependency configuration concern.

During bulk upload, from time to time, Fits directs one of our wav files to libreoffice for the creation of derivatives instead of ffmpeg. Indeed one of the Fits tools sees the file as an excel file :

<identification status="CONFLICT">
    <identity format="Waveform Audio" mimetype="audio/x-wave" toolname="FITS" toolversion="1.4.0">
      <tool toolname="OIS Audio Information" toolversion="0.1" />
      <tool toolname="Droid" toolversion="6.4" />
      <tool toolname="Jhove" toolversion="1.20.1" />
      <tool toolname="file utility" toolversion="5.30" />
      <tool toolname="Exiftool" toolversion="11.14" />
      <externalIdentifier toolname="Droid" toolversion="6.4" type="puid">fmt/141</externalIdentifier>
    </identity>
    <identity format="Microsoft Excel Format" mimetype="application/vnd.ms-excel" toolname="FITS" toolversion="1.4.0">
      <tool toolname="ffident" toolversion="0.2" />
    </identity>
  </identification>

You can reproduce the issue with this file :
MUS1959_15_372.zip

Finally we had to manually delete the sidekiq "CreateDerivatives" job because the soffice command never comes back and it ends up filling all the sidekiq "slots".

Suggested solution

We solved it by adding 'wav' to the list of disabled extensions for ffident :

<tool class="edu.harvard.hul.ois.fits.tools.ffident.FFIdent" exclude-exts="wav,dng,wps,vsd,jar,ppt,rtf" classpath-dirs="lib/ffident" />
