JSFL importPublishProfileString() crashes Animate

Report · Dec 17, 2020

Operating System: Apple macOS (Mojave and Catalina)

Animate Version: CC 18.0.1 / 20.0.1 / 20.0.2 / 21.0.1

I've been working on updating an old Flash extension our Art team uses to run smoothly on Animate CC, and most things are working pretty well now except for the export functions -- they all cause Animate to crash with a Segmentation Fault (not graceful).

After some digging I found it was crashing on any of these calls:

fl.getDocumentDOM().importPublishProfileString(...)

I figured maybe the old XML strings has settings that no longer applied, so I exported the current publish profile to check it out:

fl.getDocumentDOM().exportPublishProfileString()

I know I can make edits either using the XML class or via regular expression string replacements, so I decided to just perform updates on the exported string -- but the segfaults continued.

Finally I tried just importing the default exported profile:

fl.getDocumentDOM().importPublishProfileString( fl.getDocumentDOM().exportPublishProfileString() );

...and even that segfaulted.

After some experimentation I found that I can call importPublishProfileString() with an empty string and no crash occurs. I can even call it with an invalid string and no crash happens.

It only crashes with a valid profile string... even a totally empty (but valid) profile string:

fl.getDocumentDOM().importPublishProfileString('<flash_profile version="1.0" name="Default"></flash_profile>');

It's hard to believe such a basic function is broken, but it's been tested on two versions of macOS and four different Animate versions now across a number of the team's machines.

At this point I'm at a loss on how to proceed, so any suggestions would be appreciated!

For reference, here's the relevant portion of the stack trace.

It appears to be crashing trying to update the UI after applying a valid profile:

After some more experimentation, I have an update to this.

importPublishProfileString() -only- crashes after (via JSFL) creating a new document, switching to it, and making some modifications before importing a profile -- e.g.

var newDoc = fl.createDocument();
fl.setActiveWindow(newDoc);

// perform some newDoc edits
newDoc.addItem({x:0,y:0}, avatarToExport.avatar);
...etc... draw some lines, create and delete some elements...

fl.getDocumentDOM().importPublishProfileString(...);

If the importPublishProfileString() call is made AFTER switching to the new document but BEFORE making an edits, the crash does not occur.

So my problem is solved (yay!) but there's definitely still a big bug there to be causing a segfault.
