Firefox vs. ace.js

[Reto]

Hi,

since some time (two, three weeks?) there is a strange effect when I open a tiddler in aceEdit:

1. The tiddler is opened in the ace editor.

2. This popup appears:

This translates to "It appears that this TiddlyWiki has been saved incorrectly. Please visit http://www.tiddlywiki.com/#Download for details". 

2. When I click on "OK", this pop appears:

3. When I click "OK", then macros are rendered like this:

I am not aware of changes - beside updates of Firefox. It has version 141.0.3 now.

Using TWc 2.10.2, timimi as saver, ace-Plugin.js 0.0.20

Any idea what the problem might be?

Hi Reto, do all those macros show the same "too much recursion" error? Looks not like a problem of ace.js (by the way, the latest version of the Okido's plugin is 0.0.53). Do you have any transclutions in the SidebarOptions?

Hi Yakov, yes, all those macros show the same error.

At least the problem is triggered by opening aceEditor. No idea where the cause is.

Good hint to the latest version of ace-Plugin.j, I will update it.

[Reto]

The same behaviour also with version 0.0.53 of  ace-Plugin.js.

I can reproduce the problem in other TWc. The following two entries show the error:

* <<tiddler ToggleRightSidebar>>
* <<saveChanges>>

Hello Reto,

Can you let me know what Abego plugins you have installed and what versions.

If remember correctly in one of the plugins there is a hijack of the JavaScript forEach function, this might cause some issue's.

Have a nice day, Okido

Hello Reto,

I had a quick look, the plugins are not the problem.

The problem is in Firefox I think, the XMLHttPRequest function is depreciated by Firefox, it can no longer be run from the main tread.

With older versions from Firefox there is no problem.

This issue requires a TWC core change.

Have a nice day, Okido

Okay, thanks, Okido. Then at least it is clear why this happened.

Hm, synchronous XMLHttpRequest is deprecated indeed, but I don't see how it may cause such errors. Okido, could you elaborate your idea a bit?

We can definitely fix this on the core level, but first we should determine the issue and maybe try a plugin patch.

Hello Reto, Yakov,

I tested with Firefox 1.41.0 and TWC 2.10.2

The message "The original file '.../data/TEST-XML.html' does not appear to be a valid TiddlyWiki", is easy to replicate.
Any click on the save button causes this, cause is the missing XMLHttpRequest function.

The message about "too much recursion", I saw twice and is not easy to repeat.
I also got a message "uncaught exception: undefined", and then the whole rendering breaks down.
I will first check if ace.js removes DOM objects properly.

Have a nice day, Okido

I really appreciate you taking care of it!

Hello Reto, Yakov,

I uploaded the modified plugin to GitHub for testing, PLUGIN.

On Linux with FF 141.0 it works OK with regards to the plugin problems.

The plugin problems were caused by a function call that uses this, for some reason this caused, what is in a word, random jumps in the code in FF, in Chromium no problem.

The saving problem is not solved by the plugin, this requires intervention in a core function, maybe Yakov can give an update on this.

Have a nice day, Okido

Hi Okido,

version  0.0.55-Alpha works insofar that a tiddler gets opened in the usual black ace editor window. And "AceSave" works too. But there is no usual ace editor ui, buttons and such.

Hallo Reto,

könnten Sie bitte erläutern, was Sie mit „But there is no usual ace editor UI, buttons and such“ meinen?
Dies ist für mich nicht ganz nachvollziehbar.

Ich wünsche Ihnen einen angenehmen Tag, Okido

[Reto]

Hi Okido,

sorry, my bad: I thought there was a button bar at the top, but this is obviously not true. I was just missing syntax highlighting, all text had the same color. I checked again, syntax highlighting works now in version  0.0.55-Alpha. Again: sorry for the confusion.

Cheers

No problem Reto, thanks for letting me know.
