Re: [xwiki-users] Antw.: XAR

Looks like the history of those object is not in a great shape. Are
you able to view the history of those documents in error and access
each version ?

  Hi Eduard,

 We have proceeded as per your advice and created a cron with the URL as explained on
http://platform.xwiki.org/xwiki/bin/view/Features/Exports#HXARExport
<http://platform.xwiki.org/xwiki/bin/view/Features/Exports#HXARExport>. It however
generates a lot of (in my eyes) unexpected errors in the Log file (resulting in a Log file
size of over 500Mb). When we do an export using the Admin panel, we do not encounter this
problem.

 [example 1]
 the Page (in Bold) has only 1 version (version 1.2) present (and no minor versions).
There are no additional errors for this document.
 [example 2]
 This page (also Bold) actually has a version history. The document’s current version is
14.1 with 2 intermediate (lower) versions before 11.1 and quite a few below that.
Apparently, the export indicates that there is an error in 11.1 but I’m unable to
determine the error in the objects. The higher versions do not generate an error and I
expect that he quits after the error.

 Note: Our pages only contain Custom Objects and Comment objects. There’s no actual
content on the page.
 Note: I can not find any version information in the XAR. It seems that only a single
version is included in the Export.

 Can someone explain why this is happening or guide me towards a solution and (more
important :-)) how to correct this?

 With kind regards,

 Peter

  Hi Peter,

 Of course, though you might want to think a bit on the approach.

 1) If you want to do it in XWiki using the scheduler plugin, you have to
 write some groovy script [1] in the scheduled task that you create in  order
  to use the filter module [2] (or the old packager
module [3], whichever  you
  choose) in order to export the pages you are
interested in and save the
 result (on the filesystem or as an attachment in a page).

 As inspiration, you could check out the source code (in java) of the  export
  action [4] which is exactly what is going on when
you are exporting a  page
  from the UI.

 2) A simpler choice, IMO, would be to schedule a cron [5] task on a linux
 machine (possible the same one running the XWiki instance) and have that
 task simply download (using something like cURL [6]) the result of a
 manually crafter export URL (as detailed in our documentation [7])
 containing the list of pages to export.

 Hope this helps,
 Eduard
