Subject [jira] Commented: (MIME4J-114) Efficient Read Access To Parts Of A Parsed Document
Date Sat, 07 Feb 2009 13:32:59 GMT

    [ https://issues.apache.org/jira/browse/MIME4J-114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12671463#action_12671463

Stefano Bagnara commented on MIME4J-114:

the content-transfer-encoding for a multipart message SHOULD always be 7bit, 8bit or binary
to avoid nested encoding/decoding operations.

Javamail from 1.4 ignores a content-transfer-encoding quoted-printable or base64 for a multipart
message by default while previous javamail versions parsed correctly nested encoding. Javamail
1.4 provides a flag to enable the nested encodings (for backward compatibility): mail.mime.ignoremultipartencoding

Depending on our approach with this behaviour we could take a different approach to random
access to the mime source.

>            Reporter: Robert Burrell Donkin
>             Fix For: 0.7
> Use Case
> --------------
> Consider a large MIME document stored (as a single document) in a medium which allows
random access to the bits (for example,  a BLOB in a data store or a file.) 
> I parse the document once using Mime4J and store the meta-data (for example, in a data
store) so that I can read this data many times without loading and reparsing this large document
> I wish to be able to read efficiently a part of the document without loading the whole,
and this may happen frequently
