--------------------------------
Summary: TikaInputStream support for resetting via a factory of
InputStreams
Key: TIKA-2585
URL: https://issues.apache.org/jira/browse/TIKA-2585
Project: Tika
Issue Type: Improvement
Components: parser
Affects Versions: 1.17, 2.0
Reporter: Nick Burch
As raised in the 2.0 breaking changes thread, currently the only way that Tika
has of handling the need to fully read an InputStream multiple times is to use
`TikaInputStream.getFile()` which will spool to a temp file if not already
file-based. (Reading a few kb is handled via buffering and mark/reset, but that
doesn't scale for huge full files)
In some cases, grabbing a fresh `InputStream` is actually cheaper than Tika
spooling to a temp file, but we've no way of a caller expressing that
So, before we make too much extra use of re-processing the whole input several
times (eg for the augmenting-parsers and fallback-parsers), we should provide a
way for callers to instead supply new InputStream instances on demand
