Bug 14219 – TiddlyWiki saving doesn't work

• Status: RESOLVED
• Resolution: WORKSFORME
• Component: New Bugs

[Tommi Komulainen]

With webkit nightlies TiddlyWiki and derivatives are unable to save any changes to local files, all attempts just show a "It's not possible to save changes." error dialog with varying verbosity.

I've tried both the java (http://tiddlywiki.com/#TiddlySaver) and plugin (http://www.dcs.gla.ac.uk/~jp/tiddlywiki/) workarounds and neither one is working with webkit nightlies. Both seem to be working with Safari2.

If confirmed, this would be a P1 bug.

Could you please provide detailed steps to reproduce (as in "open this site, click this particular link, type this text, expect that behavior")?

[Tommi Komulainen]

1. Download http://tiddlywiki.com/empty.html
2. Open the local file
3. Click 'save changes' in the sidebar on the right

After following these steps in Safari 2, all I got was an error message saying "It's not possible to save changes."

Doing the same in Firefox, I got a request for additional privileges from the script, which I didn't grant, not knowing what they were needed for.

The Java workaround was verified to work correctly with TOT (works for me, and confirmed by the reporter on IRC):

1) Create a folder ~/Documents/tiddlywiki-folder
2) Create a .java.policy file, as described at http://tiddlywiki.com/#TiddlySaver
3) Save http://tiddlywiki.com/empty.html to tiddlywiki-folder
4) Open it
5) Click 'save changes' in the sidebar on the right

A new saved file appears in tiddlywiki-folder.

I don't think this is supposed to work without a Java applet or plugin in WebKit, because scripts cannot request elevated privileges, as TiddlyWiki does in Firefox code path. In the future, HTML5 persistent storage may provide a better foundation for such applications.
