Re: tika 2.4.1 'Text extraction failed' errors when dovecot+fts 2.3.19.1 passes embedded *.eml (message/rfc822) files ; org.apache.tika.parser.mail.RFC822Parser or dovecot ?

1 Aug 2022 · *with*


      This looks like zero-bytes are getting passed to Tika via dovecot.  I don't
know enough about dovecot to figure out what's going on.

i'm running
    dovecot 2.3.19.1 + fts
    tika-server-standard 2.4.1
dovecot is feeding tika backend via fts_tika
when dovecot passes data with *.eml attachments embedded, tika fails to
correctly parse/extract content
not clear if the issue is with tika, or what dovecot's passing in this
case.
other non-.eml attachments are fine.
here's the current failing procedure,
(1)
create a simple pdf
    enscript -p mime.ps /etc/mime.types
    ps2pdf mime.ps mime.pdf
(2)
send an email *with* mime.pdf attachment to
    echo "test" | mailx -s "test" -a ./mime.pdf testuser@example.com
tika processes OK
    journalctl -f -u tika
