Attachments: New constructor for JarFileSystem

Description Tomas Zezula 2009-11-23 10:45:04 UTC
Comes as a part of the umbrella issue #177274 (the slowness in GoTo type) where 1.5s from 4.7s is spent in ArchiveURLMapper.
Jarda had an idea of creating the root FileObject without need to mount the JarFS when the list on it is done the JarFS will be mounted.
Comment 1 Jaroslav Tulach 2009-11-24 05:20:58 UTC
The ArchiveURLMapper shall return the FileObject without opening the JAR. This can be done by improvements in JarFileSystem, possibly with some new API, or by creating a virtual FileObject that will later create and delegate to JarFileSystem.getRoot().
Comment 2 Jaroslav Tulach 2010-01-19 08:52:03 UTC
Let's do this.

Comment 4 Jaroslav Tulach 2010-01-19 12:16:50 UTC
Review this addition of new JarFileSystem constructor and its use in ArchiveURLMapper.
Comment 5 Jesse Glick 2010-01-20 18:15:33 UTC
Good idea.
Comment 6 Jaroslav Tulach 2010-01-25 05:21:41 UTC
