56 -== Experimental Filesystem Attachment Storage ==
57 -Storage isn't flashy and it isn't exciting, as a user you only have to think about it when it breaks.
58 -Filesystem attachment storage provides you with a means to store large attachments. All data is streamed
59 -from the upload to the filesystem without being held in memory on the way through.
60 -
61 -This means that the only limit on the size of attachments which can be stored is the size of your hard disk.
62 -
63 -Practically, this was tested using a 1GB attachment which uploaded with no problem. A 4GB attachment failed
64 -but the exception message suggests the web browser is to blame.
65 -
66 -=== Set up ===
67 -To try this out for yourself, you will need a copy of XWiki 3.0M2.
68 -Download the 5 parts of the filesystem storage:
69 -* [[Api>>http://hudson.xwiki.org/job/xwiki-platform-core/lastBuild/org.xwiki.platform$xwiki-core-store-api/artifact/org.xwiki.platform/xwiki-core-store-api/3.0-SNAPSHOT/xwiki-core-store-api-3.0-SNAPSHOT.jar]]
70 -* [[Transaction>>http://hudson.xwiki.org/job/xwiki-platform-core/lastBuild/org.xwiki.platform$xwiki-core-store-transaction/artifact/org.xwiki.platform/xwiki-core-store-transaction/3.0-SNAPSHOT/xwiki-core-store-transaction-3.0-SNAPSHOT.jar]]

75 -{{info}}Development is still progressing and these links will always point to the latest versions of the files so check back from time to time. {{/info}}
76 -
77 -Place these files in your ##xwiki/WEB-INF/lib## directory.
78 -
79 -Then make the following changes to your xwiki.cfg file:
80 -Under the "Storage" section:
81 -
82 -{{code language="none"}}
83 -#-# The attachment storage.
84 -xwiki.store.attachment.hint=file
85 -
86 -#-# The attachment versioning storage. Use 'void' to disable attachment versioning.
87 -xwiki.store.attachment.versioning.hint=file
88 -
89 -#-# Whether the attachment recycle bin feature is activated or not
90 -storage.attachment.recyclebin=0
91 -{{/code}}
92 -
93 -Then start your wiki and as Admin, open this page:
94 -##<your site>/xwiki/bin/edit/XWiki/XWikiPreferences?editor=object##
95 -
96 -Scroll down until you find:
97 -##Maximum Upload Size##
98 -and change that number to something huge like:
99 -99999999999999999 ;)
100 -Press save at the bottom of the page.
101 -
102 -Now go on and upload your giant attachments.
103 -
104 -An attachment recycle bin store is in the works but remains unfinished, the existing code **should** work with the old recycle bin (and it's memory consumption issues) but as of this writing, there exists a bug in the conversion from the new format to the old.
105 -Without a recycel bin store, deletion of attachments is final, rolling back a document will not bring the attachments back.
