/tmp filling with hundreds of gm-temp directories

[liujed]

I have Greasemonkey 2.2 installed on Firefox 31 on Linux. As I browse the web, over time, my /tmp directory fills with hundreds of gm-temp directories (e.g., gm-temp, gm-temp-1, gm-temp-2, ...), each with a zero-byte gm_script file. During my current browsing session, I have observed six of these directories being created, even as my browser sits idle.

The cause is different, but the result is almost the same (contains all downloaded files - non-zero byte files):

Temporary directory is not deleted when showing the source code:
modules/remoteScript.js
RemoteScript.prototype.showSource()

...when the user closes the tab.

[Ventero]

Ventero@f78a790 ensures that RemoteScript#cleanup is called when the tab is closed (unless it's closed by the script installation process).

I can confirm that view source on the script can cause this. But it's not just that. I also can see dozens of gm-temp directories created in a session where I never use view source.

I lost a big carefully documented comment. Oh well, the short version: I see Sync support doing this; every 10 minutes I get 4 empty gm-temp directories and the error from #2014 logged. @liujed do you have Firefox Sync enabled?

If so I think #2014 might obsolete (the rest of) this.

[intgr]

I get hundreds of /tmp/gm-temp-X directories and I haven't used the "view source" in GreaseMonkey. I have Firefox Sync enabled.

[liujed]

@arantius I do indeed have FF Sync enabled.

[arantius]

It appears that Fixing #2014 obsoleted this.

(At least, along with Ventero's fix above.)
