dMZX Forums: Better corrupt world detection? -> Archived MegaZeux Bugs -> Tracker

http://kuroneko.spec...ckup1_after.mzx

This .mzx file actually used to be an .mzx file that mysteriously got corrupted (Kubuntu thinks it's a .gz), but the way Megazeux reacted has happened to me before (and didn't bring back happy memories, though I can hardly blame MZX for that). Basically, what happened is it showed up in the directory view as a proper .mzx file but with a garbled title screen name, and when I tried to load it, it told me the world was locked and offered to unlock it. Pretty much knowing what would happen, I told it to unlock the world, and Megazeux crashed. Every time I try to load the world as it is now, Megazeux crashes.

By the file name, you could probably guess I didn't lose anything important this time, but I'm still mildly shocked that Megazeux still mistook a non-.mzx file for a valid (locked) file, let me "unlock" it, and crashes instead of displaying an error message when trying to load it. This is both a bug report and a serious request for some better file verification. I'll recover a version of this file that hasn't been "unlocked" in a little bit.

Thanks!

edit: as promised, http://kuroneko.spec...mzx/backup1.mzx

edit2: on this note, is there a way to re-"lock" these files outside of MZX? I want to see if something is salvageable at all from that old file.

edit3: checked again, and the file wasn't GZipped. I have no idea what corrupted that backup file.

Updating status to: Flagged For Future Version
Updating severity to: 5 - Critical
Updating Introduced In Version to: <2.80

This is hard to fix and I have no intention of fixing it for 2.83b.

--ajs.

Updating status to: Duplicate Entry

Since there are three or four of these reports I'm consolidating them all into a single feature request (Improved Validation for Legacy Formats).

Moving to: Archived MegaZeux Bugs

Worthless addendum 8 years after the fact: the file here is a completely valid MZX file with what looks like the result of "ls -la duskLance/backup2.mzx" prepended.
