Prevent notes from resolving more than twice to prevent infinite loop. (3.19 KB, patch)

Description Ruben Vermeersch 2007-03-26 10:54:59 UTC 
When exporting a note with circular links, the export to HTML plugin enters an infinite loop.

How to reproduce:
 * Create a note A, link to note B
 * In this newly created note B, link to A
 * Export A to HTML
 * Crash!
Comment 1 Ruben Vermeersch 2007-03-26 11:03:31 UTC 
Note that I have used both export-linked and export-linked-all.
Comment 2 Max Wiehle 2007-08-09 13:45:47 UTC 
Can confirm this. Probably needs a list of already exported notes.
Comment 3 Enrico Minack 2007-08-09 13:50:55 UTC 
confirmed for 0.7.1
Comment 4 Enrico Minack 2007-08-09 14:18:23 UTC 
The ./Tomboy/Addins/ExportToHtml/ExportToHtml.xsl (called by ExportToHtmlNoteAddin.cs) transforms a note into html and, if requested, does this recursively for linked notes. It also manages a key (look-up table) called 'note-already-loaded' to avoid re-loading notes previously being processed. So from this point of view it seems to be considered in the xsl file. Maybe xml or the xsl transformer has problems with this recursitivity...

Confirmed for 0.8.0 on Ubuntu Gutsy.
Comment 6 zerohalo 2007-10-16 03:18:42 UTC 
I'm experiencing the same, using 0.8.0 on Ubuntu Feisty. Tomboy crashes, and creates a huge HTML file (32MB) with the same note (or couple of notes) stored repeatedly a number of times. The rest of the notes are ignored. 

THis is when I choose "Export Linked Notes" and "Include all other notes". This option has become vital to me since I've moved to a Mac, and find myself unable to read my many many tomboy notes (no Mac port, snif!).
Comment 7 zerohalo 2007-11-13 03:51:42 UTC 
Since 4 people report this problem, is it possible to move it off "unconfirmed" status?
