I am trying to create/retrieve temporary files in a directory named /tmp
Based on: https://cloud.google.com/appengine/docs/standard/python3/using-temp-files
However I am seeing an error saying this is a read-only file system (as below):
I created a tmp directory myself (as below). Is it possible the tmp directory I should be accessing is located elsewhere?
Thank you for your time.
After checking your picture it seems you are trying to write into ./tmp instead of /tmp is this right?

I'm getting an error when trying to upload any type of file via Content>Files>Add File. The error reads "The file filename could not be saved. An unknown error has occurred. The file in the Upload a new file field was unable to be uploaded."
I've read through many threads and most seem to indicate a permissions problem. I've checked that all directories are configured properly. Public files are set as sites/default/files; private files are set as sites/default/files/private; and temporary is set as sites/default/files/tmp.
Then I found this error in the server logs:
[Tue Mar 27 10:49:26.932464 2018] [proxy_fcgi:error] [pid 20750:tid 140070898026240] [client nn.nnn.nn.nn:63784] AH01071: Got error 'PHP message: PHP Warning: File upload error - unable to create a temporary file in Unknown on line 0\n', referer: http://ipaddress.com/file/add
Any ideas what might be wrong here?
Thanks,

This is definitely a permissions issue.
You mention the path of the different folders (public, private, and tmp), but that is a completely different thing.
What you need to check is that user running the webserver has permissions to write on those aforementioned folders.
Now, you don't mention what server are you using, so I'll assume you're running Apache, and the Apache user and group is called apache in CentOS and www-data in Ubuntu.
You should navigate to those folders (actually to the folder where this folders are placed) and type a ls -la sentence in the terminal, to get a list of permissions for them, as well as the name of the user that owns the folders.
The Apache user needs to access and write in those folders.
I have come across the similar problem once. Solution to this problem is to give the 'write' permission to 'others' as well on tmp directory. You might wonder that this is /tmp directory I am talking about, as while uploading a file it must pass through /tmp directory to the desired location.
So give the write (other) permission to /tmp and sites/default/files/tmp directory. Hope this will help.
I have an issue.I can not access files from one folder from Linode.I can access the files present inside other folder in the same parent directory.Let me explain it properly.
When i am trying to access like my-hostname/icons/, its not coming.But at the same time if i am trying to access like my-hostname/css/ this its coming.I can not know why this type problem is coming.When i am chceking it inside putty,its coming like below.
You can check above the icons folder is showing some other color which i can not access.Here i need to access this using the same domain name.Please help me.
It seems sticky bit is activated.
Try
chmod -t icons/
Could you post the permissions of the files/folders there? You can do it by running
ls -l
When you are in that folder, and provide us the output.
I'm getting errors when I attempt to run my project deployed to app engine. I see issues like:
java.lang.ClassNotFoundException: com.seattleglassware.AuthServletSupport$$anonfun$finishOAuth2Dance$1$$anonfun$apply$33$$anonfun$apply$34$$anonfun$apply$37$$anonfun$apply$40$$anonfun$apply$41$$anonfun$apply$42$$anonfun$apply$45$$anonfun$apply$47$$anonfun$apply$48$$anonfun$apply$49
The class name looks reasonable (well, for certain values of reasonable - this is code generated by the Scala compiler). I see the file in my local web/WEB-INF/classes/com directory and I can decompile it with javap (so I don't think it's corrupt or anything silly like that.) Everything works fine running on a local debug server.
Even more strange, I can pour all the .class files in web/WEB-INF/classes into a jar file like this:
cd to the web/WEB-INF/classes directory
jar cf ../lib/classes.jar .
And now, if I upload the project (pressing the deploy button in Eclipse), I don't see those ClassNotFoundException errors. Delete the jar file, re-upload the project, get the errors again.
I'm wondering if there's some sort of limit on the names of .class files? Or something else happening in the deployment process that's causing this to happen?
EDIT: running from the command line made this much more clear (using maven now):
SEVERE: Invalid character in filename: WEB-INF/classes/com/seattleglassware/AuthServletSupport$$anonfun$finishOAuth2Dance$1$$anonfun$apply$33$$anonfun$apply$34$$anonfun$apply$37$$anonfun$apply$40$$anonfun$apply$41$$anonfun$apply$42$$anonfun$apply$45$$anonfun$apply$47$$anonfun$apply$48$$anonfun$apply$49.class
But it still looks to me like that's a valid filename.
The inclusion of "special" characters in the file name may be the issue here.
There is currently an open issue regarding "special" characters in project file names.
Issue 2211: Special characters are not supported in the filenames in the project
The original issue was reported by a Python App Engine user, however if you look in the comments you'll see that it apparently affects Java users as well.
I'm writing a fuse file system that mount one directory to itself. I want to log some calls (flush for example). I've started to adapt fuse tutorial sample code. If I try to bind any directory it works great:
./bbfs -o nonempty ./test ./test
but if I try to bind particular root directory ("/"):
sudo ./bbfs -o nonempty / /
no one line is in logfile.
Is it possible?
My mangled version of sample program. I've changed only bbfs.c file.
You can't mount a FUSE filesystem (or any other type of filesystem, for that matter) at /, because your root filesystem is already there.
Doing so would be disastrous anyway, as mounting a filesystem at a path makes any files which previously existed under that path inaccessible. You can't use FUSE as a filter like this -- you will need to find another solution to whatever it is you're trying to do.
I'm making a filesystem using FUSE, and know I have a doubt. When I use the "cd" command in the new filesystem, it changes to directories that doesn't exist.
For example, if the directory "m" doesn't exist, and I make a "cd m" it changes to that directory.
Which is the function that FUSE calls when the directory is changed? Why is the app doing the problem I describe?
Thanks!
Are you implementing getattr? and if so, are you making sure to return -ENOENT if the path they give you doesn't correspond to a file or directory in your system?
