NS_FILE_IS_LOCKED on FF27 / Win7_64

[steady286]

Content cannot be saved using the setup named above. Error Message is:

[Exception... "Component returned failure code: 0x8052000e (NS_ERROR_FILE_IS_LOCKED) [nsIFileOutputStream.init]" nsresult: "0x8052000e (NS_ERROR_FILE_IS_LOCKED)" location: "JS frame :: chrome://tiddlyfox/content/overlay.js :: <TOP_LEVEL> :: line 98" data: no]

The error message suggests that the file is locked by another process. Possibly an instance of Firefox that crashed? Is the file on a network drive?

Thanks @steady286 - does it work OK using files on your main hard drive?

jeremy, on a hard drive it works... magic ! is this some kind of security feature? at least on linux/ff 25.0.1 it also works on my usb - stick... best regards, gerhard

Hi @steady286 I think it is probably an issue with recent versions of Firefox. It might be worth checking with the latest nightly of Firefox to see if you fare any better?

I have something like this. It only happens with a large tiddlywiki. I deleted a couple of tiddlers and then it stopped happening. Is anything in tiddlyfox size-dependent?

Also, where is the permission stored (such that the first time, tiddlyfox asks permission, and after that, it doesn't) ?

Wow, interesting. We've not come across anything like that before. Can you reliably duplicate the problem? What size is the wiki file?

Also, where is the permission stored (such that the first time, tiddlyfox asks permission, and after that, it doesn't) ?

TiddlyFox uses Firefox's built-in permission manager:

https://github.com/TiddlyWiki/TiddlyFox/blob/master/content/overlay.js#L155

I don't think that Firefox provides a user interface for these permissions.

Thank you, Jeremy,

Unfortunately (?) it was not fully replicable. It repeated on a renamed copy of the file, and on a Firefox restart, but not a computer reboot... I haven't seen it again, luckily.

Actually I stress FF a lot, and I think it has memory leaks or something else... it eventually hangs or crashes.

The tiddlywiki was about 10 megabytes; Firefox memory at 2 gigabytes.

I suspect the permission is stored in the mysql settings database inside the Firefox profile. If so, a Firefox add-on can be used to browse / modify the data.
