Hey guys,
I confirm: before 3 days of intensive computer use without UbuntuOne, i have now just ONE file .goutputstream- xxxxxx in /home. ( With UbuntuOne installed, in 2-3 days of use, i have easily 10 goutputstream files).
At this point, I think the strategy "Remove Ub.One, Wait and Say" can be to consider.

ok so i checked it with a stopwatch and it seems that upon confirmation of shutdown the file is being created
Karolis (reklamukibiras) wrote : | #28 |
really sorry for tripleposting, but on the fly bug research lead me to this:
the bug is related to "X Window authorization" or "xauth"
according to wikipedia a cookie based access:
"These cookies are created by a separate program and stored in the file .Xauthority in the user's home directory, by default."
if i run `strings .Xauthority` i get almost the same as in .goutputstream*DW:
<3 identical lines (check two posts up)>
<2 lines that repeats the first two>
question remains - how do these .Xauthority get's partially duplicated into bunch of .goutputstream* on every shutdown?

Google shows instances of this bug going back to at least 2009. I had 19 of these files covering the first 13 days of May, starting when I installed Pangolin and ending when I installed Mint 12/Cinnamon to overcome an intractable printer problem. In my case all 19 files were zero bytes.

I have the same issue as everyone else, nothing much else to add. I don't recall these being generated in prior Ubuntu versions.
Just a thought since others have suggested removing Ubuntu one solves the problem and others that logging out before shutdown does. It would seem something needs to be changed with how shutdown stops U1. Just a thought.

I see no any .goutputstream files any more. I did nothing just installed all pending updates.
Dennis Baurichter (d-baurichter) wrote : | #35 |
Summary of previous comments:
- blank files (#25, #31) or partial copies of .Xauthority (#11, #15, #26 / #28, mine too)
- in Ubuntu and Xubuntu (files shown by Nautilus, Thunar and ls; no file manager problem)
- created on direct shutdown (but not logout -> shutdown)
Workaround: put 'sh -c "rm ~/.goutputstrea
My Software:
- Ubuntu 12.04 amd64 (up-to-date)
- file-roller installed but usually not running (also not running on shutdown: see below)
- No gtk-recordmydes
I tried to find out which software is creating these files. I used (e.g.) inotifywait (package inotify-tools) and lsof, but it didn't work out. Probably the .goutputstream-* files are open only very short (too short for my script to catch it although run with niceness -19).
Then I simply logged all processes running with my UID (1000) in an endless loop (i.e. until the script was terminated because of shutdown). I'll attach the script and its shortened output (removed duplicate blocks with no changes in process list and many blocks at the beginning).
The output also contains a line stating "FILE CREATED!!!" when the ~/.goutputstream-* file is created. Just before / after this gnome-session quits and lightdm is started by UID 1000 (not root as usual). I don't know, why it is started, but it is also the next process which quits.
lightdm also uses the ~/.Xauthority file. See
strings `which lightdm` | grep -iE 'output|xauth'
and the source code of lightdm:
grep -ri xauthority /path/to/
lightdm is used by Ubuntu and Xubuntu, but not Kubuntu. This fits to the previous comments.
Maybe also related: GIO (part of glib)

Get own processes using this:
ps -o comm= -U 1000 -u 1000 | while read cmd; do file=$(which "$cmd") || file=$(locate -b "$cmd*"); strings -af $file | grep -E ': g.*output.*stream'; done > search.out
I assume it's a problem with lightdm, but I can't fix it. I hope my information helps.

I don't know if it's specific to unity-greeter. Maybe an Xfce / LXDE user can try the script I attached. There are also some Xubuntu users which commented on this bug.
For those who want to try my script: You should start it only just before requesting shutdown or restart. It produces a lot of output into the logfile (more time -> more output).
> do you mean that it happens at logout?
It happened on shutdown. It seems that makes a difference here (between logout and shutdown I mean; see comment #29).
I did this:
- rm ~/.goutputstream-*
- start ps-log.sh: sudo -b nice -n -19 sh ./ps-log.sh
- start gnome-session-quit --power-off and click on "Shutdown" (This should be the same as top-right button in Unity -> Shutdown -> Shutdown.)
After restarting my computer I looked into ps-log.out:
...
COMMAND
gnome-session
...
FILE CREATED!!! <-- This is the point where my script first sees an ~/.goutputstream-* file.
COMMAND
lightdm
...

definitely not specific to unity-greeter. xfce4-session on xubuntu12.04 produces this from Dennis script:

Dennis Baurichter (d-baurichter) wrote : | #40 |
Thank you Karolis! I downloaded your file and merged the duplicate blocks (search + replace). It's 330 lines now, instead of 3900.
Here are the diffs:
$ diff PART1 PART2
2c2
< sh
---
> lightdm # LightDM start
$ diff PART2 PART3 # "FILE CREATED!!!" is between these two (empty diff)
$ diff PART3 PART4
2d1
< lightdm # LightDM end
$ diff PART4 PART5
5d4
< xfconfd
11d9
< xfsettingsd
14d11
< gvfsd
$ diff PART5 PART6
7d6
< xfwm4
# ... and so on (only processes quitting or becoming "<defunct>" and then quitting)
When I ran my script lightdm appeared right after "FILE CREATED!!!", but it probably spawned a bit earlier, i.e. right before .goutputstream-* is created. It was also the first process to quit after the creation of .goutputstream-*.
Now, in a Xfce session, we have lightdm spawning right before .goutputstream-* is created and quitting afterwards again.
It's not a proof, but an indication.
And I have no clue why it is started (by user 1000!) at all ...
Anybody else?

I have the same issue and I have a brand new Lenovo laptop with a fresh install of 12.10 on it. I just deleted all of my .goutputstream-* files and I am going to watch it to see if I can determine when they are created. So this is not a hardware problem or 3rd party software issues. It is happening with a clean install on a new laptop.
Happens in Raring too. I have a command in /etc/rc.local to run:
rm /home/andy/

These .goutputstream-xxx files get created everytime Ubuntu 12.04 shuts down or starts up.
I tried to fresh install several Ubuntu 12.04 flavors on several laptops and desktops to check this behavior, and it happens with ALL distros based on Ubuntu (Kubuntu, Xubuntu, UbuntuStudio, Mint, etc.).
I noticed that every time there is a file write activity, a temporary .goutputstream-xxx is created in the folder where this file write activity accours.
Say i copy a file from ~/Downloads to ~/Documents, in the ~/Documents folder there is a temporary .goutputstream-xxx file created which gets automatically deleted when the copy action finishes.
In the $HOME folder seems that these temporary .goutputstream-xxx files are not cleaned up when the Ubuntu system starts up or shuts down.
I normally run a start up script that automatically deletes these .goutputstream-xxx files in my $HOME, but it would be better if the bug that causes this is fixed.
This only happens in *buntu 12.04 not earlier.
I haven't tried 12.10.
Have the same issue. All the files have 0 bytes but also contains "1" text inside. Date of creation seems to be same as shutdown. Affects me in two computers.
Nicolas M. (nicolas-m-le-zer0) wrote : | #105 |
As reported before, all the “.goutputstream
Now, let's focus on the other part of the problem. On every session close, LightDM needs to clean ~/.Xauthority. According to #28, there can be lines in .Xauthority that shouldn't be erased, though the last line seems to stand for the current session and should be deleted when the session is closed. I don't know well how it works, but some process (most likely XAuth) is called to remove the last cookie of .Xauthority. It works fine when you only close your session, but when you shutdown from an open session, it looks like LightDM doesn't take time to close it properly before shutting the whole system down. o_O
That results in a “.goutputstream

Shouldn't temporary files be created in /tmp rather than $HOME?
Paddy Landau (paddy-landau) wrote : | #107 |
@cousteaulecomm
That depends on whether the contents are potentially private. As this is related to .Xauthority, according to nicolas-m-le-zer0, these files should go to the user's home folder.
rpr nospam (rpr-nospam) wrote : | #108 |
@paddy-landau: Every application that writes to /tmp can change permissions of the files in order to limit access only to the owner of the files. Log on to Ubuntu as a guest and you'll find the complete user's home directory in the /tmp/guest-* directory.
@nicolas-m-le-zer0: You probable meant to say that comment #102 mentioned a bug fix.
Paddy Landau (paddy-landau) wrote : | #109 |
@rpr-nospam — thanks for the clarification. I am aware of the permissions ability, but it is further improved if the user uses encryption on his home folder. Anyway, that is probably suitable for a separate discussion.
Regarding comment #105 by @nicolas-m-le-zer0, I have been automatically removing .Xauthority (via a logout script) when logging out since I read that comment. Unfortunately, it did not solve the problem. The .goutputstream* files were still being created and left in the home folder. I have reverted to deleting the .goutputstream* files in the logout script.

I get these a lot with ubuntu 12.10, though they aren't really a problem as I have a script run with crontab to delete them on boot
`@reboot rm ~/.goutputstream-*`
in `crontab -e`.
It has something to do with file management, I think.
just speculating, but because everyone who has these have them with some process that edits files, like Ubuntu one/dropbox, or when booting up/shutting down. What if the process that creates goutputstream for changing files hasn't fully loaded or is shut down in the middle of an operation? (just speculating).

IMHO making all "Shutdown" buttons in various *DEs work like "Logout then shutdown" can workaround or even fix many bugs including this one, especially for linux newbies. But it's a task of *DEs developers, not only Ubuntu/Unity ones.

Since installing 12.10 have noticed that a warning box indicates a process is not shutting down as quickly as it should be ref signon-ui at shutdown time. This could be related to the use of Ubuntu One sign in with relation to the Backup app. If Backup is closed from desktop session an Ubuntu One sign in box appears.
After noticing the hidden goutputstream files and doing a websearch then looking here it appears there is no definite cause to this happening. Reading comment #33 did motivate me to note my own observations but do not have programming experience to help identify what is the actual cause of the goutputstream files in home folder. Ref https:/

This command is similar to add. The main difference is that instead of requiring the user to supply the key data, it connects to the server specified in displayname and uses the

<snip>
EXAMPLE
The most common use for xauth is to extract the entry for the current display, copy it to another machine, and merge it into the user's authority file on the remote machine:
% xauth extract - $DISPLAY | ssh otherhost xauth merge -
The following command contacts the server :0 to create an authorization using the MIT-MAGIC-COOKIE-1 protocol. Clients that connect with this authorization will be untrusted.
% xauth generate :0 .
<snip>
BUGS
Users that have unsecure networks should take care to use encrypted file transfer mechanisms to copy authorization entries between machines. Similarly, the MIT-MAGIC-COOKIE-1 protocol is
not very useful in unsecure environments. Sites that are interested in additional security may need to use encrypted authorization mechanisms such as Kerberos.

I also have.goutputstream files polluting $HOME.
But I don't use amd64 nor lightdm.
I use Lucid ubuntu 10.04-4 with gdm
Intel(R) Pentium(R) M processor 1400MHz
Let's tell me which other informations could be useful.
Thanks

I have to add this : I mostly have .goutputstream files also in my FAT32 personal data partition. Their content is
sometimes an intentionally pasted text (Ctrl C, Ctrl V),
sometimes a small part of a bigger txt file, but with no use of (Ctrl C, Ctrl V).

I discovered how to reproduce the bug with Gedit and Firefox :
- Create a text file, and save it with this encoding type :
"Occidental (ISO-8859-15)"
- Type several lines in it. Save it again.
- Go to a web page with a certain encoding, UTF8 compatible, but not compatible with "Occidental (ISO-8859-15)".
- Copy a few lines including, for instance, go-to-note, or (french) "puce" (you know, that sort of symbol you can put, instead of a number or a letter, at the beginning of a line or of a paragraph, when listing items). (Sorry for my rusty english and the lack of precision).
-5) Then go back to your text file : paste the formerly copied lines from the web page, but NOT at the beginning.
- Have a look at the clock on your pc, memorize the time. Try to save your file : you get normally an error message, pointing the different encoding types. (You could save the copied text if you created for it a new UTF8 encoded file. It is not necessary for this experience.)
Here you are ! the new .goutputstream-
- Gedit, "open file", and you can see, in the dialog box, your new .goutputstream-
- If you open it, you'll find only the first "Occidental (ISO-8859-15)" lines of your file, but not the end : the saving stopped when encountering different encoding.
In order to get a 0 ko .goutputstream-

I made a small mistake in my #119 comment :
if I paste at the very beginning of the Occidental (ISO-8859-15) file, I do NOT get an empty file : my .goutputstream-
And one more time, I got this with a 32 bits Pentium M processor, GDM and Ubuntu 10.04 4.

Hi, I have same bug. A new .goutputstream-xxx is created at every shutdown of PC.
I use gnome-panel on ubuntu 12.04 64 bit. Any suggestions?

Same trouble here.
Win7(Host) running VirtualBox 4.2.16
Linux Mint 14 Nadia Kernel 3.5.0-17-
Guest applications Geany(1.22), Pluma(1.4.0), and Gedit (2.30.4) cannot save to existing file.
Must create new file for each save on the Vbox shared folder. Other local(guest) folders work fine.
Did not start until Virtualbox updated to 4.2.16 no problems with setup before that.
Attempting to save an existing file with modifications results in files with names like (.goutputstream
Two solutions I have found so far are:
1.) save-as a new file name each time I make a change. (terrible)
2.) open a terminal session in that folder and use nano or vi to edit text file. (no problems)
So it seems that the drive "mount" for the shared folder is ok as nano can edit files, but the "gui apps" have an issue.

I am not able to log on my computer (12.04), and I noticed that everytime lightdm failed to log me in, there is a .goutputsteam-xxxx file and a sedxxxx file created under my home directory.
my computer runs nis/autofs with a home directory mapped on a file server.
I believe the bug I've seen is related to Bug #1004515, but not sure how it is related to this bug. just post here in case someone can make sense of it.

It seams like it's fixed in saucy. I encountered the trouble in precise and it seams it was related to X/lightdm because of "MIT-MAGIC-COOKIE" it contains. It often occurs at the time I shut down the computer (the friday afternoon after five days being up or suspended).
Brian Murray (brian-murray) wrote : | #129 |
The commit mentioned by seb128 in comment #102 has been committed to glib2.0 in Saucy, so that bug task will be marked as Fix Released. However, it should probably also be fixed in Ubuntu 12.04 (Precise).

Paddy Landau (paddy-landau) wrote : | #131 |
@brian-murray: For 12.04, unless this bug causes failures for people, I wonder if the fix is worth the potential risk in an LTS, especially as the next LTS, 14.04, is only 6-7 months away.
However, if you do release the code for testing, I shall be happy to test it.
Jochen Fahrner (jofa) wrote : | #132 |
I found those files not only in my $HOME, but also in my NFS mounted NAS.
houstonbofh (leesharp) wrote : | #133 |
I know that 14.04 is out. However, it has regressions for many people and so 12.04 is still in wide use. The fact that this is still a bug on a new system after 2 years is truly sad.

Happy to test an update Brian, I would like to see this bug closed on Precise.

I was until recently using ubuntu studio quantal 64 bit (now using trusty) and I happened to run across this in the apparmor profile for evince:
# evince creates a temporary stream file like '.goutputstream
# directory a file is saved. This allows that behavior.
owner /**/.goutputstr
This discovery has I think been reported here before, but in case it's useful to say, I thought to check my backup drive and discovered that indeed those goutputstream files were still piling up in ubuntu studio quantal. For example I have a backup done on 2014-06-18 and there are 3 of those files in my home directory; another backup dated 2014-04-08 has 14.

If people stopped spamming bug reports I could find out what the cause is. At this point, with all the meaningless waffle and crap I just can't be bothered.
I think that is connected to bug 983059 ,sounding like your hard disk is going bad. wiki.ubuntu. com/BugSquad
