Viorica Visan created TIKA-2443:
-----------------------------------
Summary: Plain text file identified as rfc822 and which can cause
StackOverflowError
Key: TIKA-2443
URL: https://issues.apache.org/jira/browse/TIKA-2443
Project: Tika
Issue Type: Bug
Reporter: Viorica Visan
I have a file called test.txt, containing only:
Date: 06/25/2014 15:54:19
And some more text I am writing. This will
be detected as rfc822
This file is detected and parsed as message/rfc822.
I think the magic rule on "Date: " is too strong and it should have detected
only as plain/text file. It looks to me like the reverse of
https://issues.apache.org/jira/browse/TIKA-879
We noticed this issue, because we have a large log file, which has many lines
with Date, Log level and Message which is parsed as message/rfc822 (only
because it starts with "Date:") and which throws
StackOverflowError in the end.
Is there some workaround to make this rule weaker ? through configuration ?
We use DefaultParser and everything default. We use tika in 1.11 version, but
we tried also with tika 1.16 and we saw the same StackOverflowError (which
probably again happened because it was parsed as a rc822 type).
The only workaround that I found was to add
custom-mimetypes.xml like this
<mime-type type="text/plain">
<magic priority="70">
<match value="Date:" type="string" offset="0"/>
</magic>
</mime-type>
Would you recomend some other workaround to make sure the file does not get
parsed as rfc822 ?
And I have another question: can this custom-mimetypes.xml be specified from an
external location?
Many thanks.
