[Bug 65581] New: add optional support in ZipArchiveFakeEntry to use
a temp file
https://bz.apache.org/bugzilla/show_bug.cgi?id=65581
Bug ID: 65581
Summary: add optional support in ZipArchiveFakeEntry to use a
temp file
Product: POI
Version: 5.0.x-dev
Hardware: PC
OS: Mac OS X 10.1
Status: NEW
Severity: normal
Priority: P2
Component: POI Overall
Assignee: dev@poi.apache.org
Reporter: fanningpj@yahoo.com
Target Milestone: ---
Currently, ZipArchiveFakeEntry will read all the bytes of the file into memory
unless there are more than 2GB (Integer.MAX_VALUE) - in which case it throws an
error.
The workaround is to load the data from a java.io.File instead of an
InputStream but this may not be obvious or straightforward.
Aim is to have a configurable value at which ZipArchiveFakeEntry creates a temp
file (or an equivalent class).

--- Comment #2 from PJ Fanning <fa...@yahoo.com> ---
added implementation using r1893421
Using this will mean all zip entries with greater than 50Mb decompressed data
will be put in a temp file instead of kept in memory.
ZipInputStreamZipEntrySource.setThresholdBytesForTempFiles(50000000);
This only affects users when they read files using Input Streams instead of
reading directly from a java.io.File.

IOException("ZIP entry size is too large or invalid") is the existing exception
