Nick Burch commented on TIKA-863:
---------------------------------
I'm not sure if we should be setting it as AutoDetectParser.class on the
context or not.
Part of me thinks that we should be setting it as Parser.class, if the user
hasn't already set one. However, there is an issue that the parser set for that
may be expecting something slightly different, eg an embedded document rather
than effectively the core document, though you could argue that the mime
contents are all embedded.
The second worry is with attaching additional objects to the ParseContext
automatically. A user may choose to not set a recursing parser on the
ParseContext, because they don't want embedded resources. If we add one, and
the email contains a word document with an embedded excel spreadsheet, then
suddenly because we added a Parser to the context recursion will trigger
> MailContentHandler should not create AutoDetectParser on each call

> MailContentHandler is called from RFC822Parser, and it creates
> AutoDetectParser on each call to parse(...). The process of creating
> AutoDetectParser involves reading TikaConfig (not cached), which in turn
> involves parsing XML config files. Apart from the fact that this process is
> wasteful and heavy, in addition in a highly concurrent setup it leads to
> multiple threads blocking on SAX parser creation.
