1342689 - "Unix error 0 during operation xxxx on file"

Status: RESOLVED WONTFIX

(Toolkit Graveyard :: OS.File, defect)

Description

[Mark Hills]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20170125094131

Steps to reproduce:

Operations involving saving files fail in the browser, and it is not at all clear what the reason is.

Tested: Firefox 45 ESR, Firefox 51 on Slackware Linux 14.2.


Actual results:

* saving files produces "Failed" message but with no explanation in the UI or console

* installing add-ons (eg. AdBlock Plus) states "There was an error installing" with some dump in the console.

* saving web pages (eg. Ctrl-S) states "Failed" in the download manager

In cases where a message is dumped to the console, they are often of the form below (often buried in amongst a longer message)

console.error: 
  Could not write session state file 
  Message: Unix error 0 during operation move on file /home/mark/.mozilla/firefox/p37j3c4k.51/sessionstore-backups/recovery.js (Success)



Expected results:

Operation should succeed -- saving file, or installing add-on.
