Notes

2018-12-01

  • Switch CGSpace (linode18) to use OpenJDK instead of Oracle JDK
  • I manually installed OpenJDK, then removed Oracle JDK, then re-ran the Ansible playbook to update all configuration files, etc
  • Then I ran all system updates and restarted the server

2018-12-02

  • The error when I try to manually run the media filter for one item from the command line:

  • A comment on StackOverflow question from yesterday suggests it might be a bug with the pngalpha device in Ghostscript and links to an upstream bug
  • I think we need to wait for a fix from Ubuntu
  • For what it's worth, I get the same error on my local Arch Linux environment with Ghostscript 9.26:
$ gs -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 -sDEVICE=pngalpha -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r72x72 -dFirstPage=1 -dLastPage=1 -sOutputFile=/tmp/out%d -f/home/aorth/Desktop/Food\ safety\ Kenya\ fruits.pdf
DEBUG: FC_WEIGHT didn't match
zsh: segmentation fault (core dumped)  gs -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000
  • When I replace the pngalpha device with png16m as suggested in the StackOverflow comments it works:
$ gs -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 -sDEVICE=png16m -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r72x72 -dFirstPage=1 -dLastPage=1 -sOutputFile=/tmp/out%d -f/home/aorth/Desktop/Food\ safety\ Kenya\ fruits.pdf
