Problems saving since updating to latest tiddlydesktop

[Dan]

Hi All,

I've been chasing a strange problem or problems since upgrading to the latest TiddlyDesktop (14) from the previous release. I only use TiddlyWiki in TiddlyDesktop and I don't use the single html file version. All my wikis use folders and I only use macOS.

Since I upgraded I've had occasional problems with hanging while TiddlyWiki is trying to save (cloud icon turns red and stays red). Quitting allows me to restart and work but, of course, unsaved changes are lost. I've had trouble pinning down the cause enough to even ask a question but now I think I might be on to something. I discovered there are a few tiddlers in my wikis that have type "application/x-tiddler." I don't even see that type documented in the ContentType tiddler on tiddlywiki.com, though it looks similar to the type for classic tiddlers. These display fine but opening one to edit it immediately causes the hang. I "fixed" these by opening the problem tiddlers in a text editor and pasting the text and fields into new tiddlers.

I thought that I had fixed my problem but I've discovered the following. I can create new tiddlers with the + button. These have no type. There is no type displayed while editing and no type is present when I open the tiddler in a text editor. For example

created: 20200624180914393

modified: 20200624180941199

tags: 

title: A New Tiddler

testing

If I then drag that .tid file into another wiki and import, it has the type "application/x-tiddler" in a .tid.meta file. For example-

created: 20200624180914393

modified: 20200624180941199

tags: 

title: A New Tiddler

type: application/x-tiddler

The .tid file that goes with the .tid.meta file contains the tiddlers text

If I attempt to edit it in TiddlyDesktop, the sync icon turns red and stays that way. 

I thought I must be doing something strange. I have wikis with thousands of tiddlers in them and some homemade plugins that mean I have plenty of opportunity to mess something up but I have now tried this with two totally fresh wiki folders that had nothing in them but a tiddler folder and a tiddlywiki.info file. I've tried with both the info file that I have been using for years (and have no idea where I got it, but it has been fine) and also with the example info file for IIS on tiddlywikis.com. The behavior was the same both times. I can't think what else I can do to try to eliminate more possibilities user error from my testing.

My standard wiki setup is full of buttons that create new tiddlers. While I could try to find them all and make sure that they explicitly set the type to "text/vnd.tiddlywiki," at this point I'm not sure that would fix things, and this behavior seems wrong in any case.

Does anyone have any suggestions?

P.S. Please don't focus on these but possible clues I have are that the large wiki that I was working with when I discovered the tiddlers with type application/x-tiddler has become so slow that it is unusable- I can't type more than a few characters into it before I have to wait. As far as I can tell, I can copy everything to a new wiki folder and it works fine, so maybe something in the TiddlyDesktop backstage that refers to that wiki has become corrupted along the way. The other odd thing I've seen is that on occasion i've had things hang while commenting out a line in a tiddler but only if I start with the end of the line. This might only be happening when there was some other problem, since it never seemed to be consistent. For example, I might get a hang at a stage when the line I was working on looked like this-

Line that is to be commented out--

So the final > never appears. If instead I start with <!-- at the beginning of the line then terminate the comment, no hanging would occur.
