How to debug my unload-able Wiki

[TonyM]

Folks,

My Key TiddlyWiki for researching TiddlyWiki is failing to load and I would appreciate some suggestions on how to identify the problem.

On opening the wiki I get the errors

Internal JavaScript Error

Well, this is embarrassing. It is recommended that you restart TiddlyWiki by refreshing your browser

too much recursion

I can no longer open tiddlers or sidebar tabs, and can see the odd popup menu I have, but no more.

I suspect it is something I did recently, but I am not sure what, because it occurred late at night and I decided to leave it lest I do more damage.

I have tried opening in safe mode, no luck,

I have removed an Item in default tiddlers (using a text editor), removed a recent rawmarkup tag to no effect

Moving forward?

Can anyone share some tips for debugging this. I would love to see where this recursion is Occurring so I can disable it. Firefox and chrome are available with Firefox my favourite.

Thanks in advance

Tony

Post script:

On refresh a stray pre is appearing on the Browser address bar TiddlyWiki5.html#%2Fpre> and in my side bar /pre>

 

 On attempting to import all the broken wikis tiddlers into a new empty tiddler in only attempts to import a subset of core tiddlers and no more.. Ie even the import facility may be breaking.

if you load your broke tw, then right click and select 'inspect element' you might get a clue

[TonyM]

I did that BJ,

And I am clueless.

This occurs in safemode and on other tiddlers in the address bar.

I expect it is something I did in a recent tiddler, but have no way I can find to review the let tiddlers edited from the text editor (yet).

this is a real pain

Regards

Tony

Grandpa speaking ... erm ... didn't you backup?

[Arlen Beiler]

That being said, it is probably not lost, especially if the file size is about the same. It looks like there is a pre tag somewhere that is messing things up. But I can't think where it would be. You said you manually removed a tiddler, which is where pre tags are used. Are you sure you removed it correctly?

I thought backups were occuring under tiddlyserver but when I upgraded and created a new folder I did not also create the backups folder. At least this is what I thought happened. Further I discoverd my synology cloud station was not syncing the folders either.

In side the more information I found this occuring multiple times

Arlen,

I am confident because "I have removed an Item in default tiddlers (using a text editor removed a title only), removed a recent rawmarkup tag to no effect" and other tags -- not removed a whole tiddler.

I appear to have located the last hour any tiddler was edited 2018062207 so I can review those, but their are many.

In the attachment we can see what leads into the loop, and the red line I added shows what then occurs to infinity/ the too much recursion limit.

What would be using those js functions?

Chrome reports a subtly different message
