c3.php throwing PHP Warnings with Vagrant about c3 HOT 7 OPEN

@olemartinorg Any idea what might be causing this? Issue caused in the code of your last commit.

Thanks in advance!

Huh.. I think this must be a problem with the file system mirror inside the Vagrant VM. I've had strange problems like this with the VirtualBox shared folder drivers before. Can you check a few things for me?

1. Connect to the VM as the root user and try to touch a file in the same directory. Do you still get a permission denied error? Root should have access to everything, so that's a sure sign there's something going on with the shared folder.
2. What are the permission settings on the folder on the host machine? What are you running on your host, is it win/mac/linux?
3. On the VM, try 'stat someFileThatDontExist' and then create it on your host machine (not on the VM!). After that, run 'ls -l' in the folder to see what the permissions on that (now existing) file is. There's a bug in some older version of the VirtualBox drivers that ends up marking the file with a lot of question marks on the permissions fields, and you can't read it on the VM until after a reboot.

Did you find a solution, @austintino?

Hi @olemartinorg,

Apologies for the slight delay in replying. You can find the answers to your questions below.
As stated above, the c3tmp directory is created by running the functional tests but then fails to be be able to write files to it which is very peculiar. How the information below helps.

1. Connect to the VM as the root user and try to touch a file in the same directory.

vagrant@ubuntu: ssh root@locahost
root@ubuntu:~# whoami
root
root@ubuntu:~# touch /var/www/phpapps/api.testurl.test/tests/_output/c3tmp/testfile.txt
root@ubuntu:~# ls -l /var/www/phpapps/api.testurl.test/tests/_output/c3tmp/
total 0
-rw-r--r-- 1 vagrant vagrant 0 Aug 23 11:37 testfile.txt

No issues creating a file in this directory. I had tried this before and found the same results.

2.a What are the permission settings on the folder on the host machine?

MyName:api.testurl.test thisismyname$ ls -l /Users/thisismyname/Sites/api.testurl.test/tests/_output/
total 1512
-rw-r--r--  1 thisismyname  staff    1631 23 Aug 11:30 GroupTokenCest.validGroupToken.fail.html
drwxr-xr-x  9 thisismyname  staff     306 23 Aug 11:33 blah
drwxr-xr-x  3 thisismyname  staff     102 23 Aug 11:37 c3tmp
-rw-r--r--  1 thisismyname  staff  766071 23 Aug 11:31 coverage.serialized

2.b What are you running on your host, is it win/mac/linux?

The host machine is

iMac, Late 2009
macOS Sierra Version 10.12.6

The VM is

VirtualBox
Version 5.1.18 r114002

Vagrant 1.9.2
Ubuntu 14.04.5 LTS (GNU/Linux 4.4.0-31-generic x86_64)

3. On the VM, try 'stat someFileThatDontExist' and then create it on your host machine (not on the VM!). After that, run 'ls -l' in the folder to see what the permissions on that (now existing) file is.

On the VM:

vagrant@ubuntu:~$ whoami
vagrant
vagrant@ubuntu:~$ stat /var/www/phpapps/api.testurl.test/tests/_output/c3tmp/doesntexist.txt
stat: cannot stat ‘/var/www/phpapps/api.testurl.test/tests/_output/c3tmp/doesntexist.txt’: No such file or directory

On the host:

MyName:~ thisismyname$ stat /Users/thisismyname/Sites/api.testurl.test/tests/_output/c3tmp/doesntexist.txt
stat: /Users/thisismyname/Sites/api.testurl.test/tests/_output/c3tmp/doesntexist.txt: stat: No such file or directory
MyName:~ thisismyname$ touch /Users/thisismyname/Sites/api.testurl.test/tests/_output/c3tmp/doesntexist.txt
MyName:~ thisismyname$ ls -l /Users/thisismyname/Sites/api.testurl.test/tests/_output/c3tmp/doesntexist.txt
-rw-r--r--  1 thisismyname  staff  0 23 Aug 11:55 /Users/thisismyname/Sites/api.testurl.test/tests/_output/c3tmp/doesntexist.txt

Any update @olemartinorg ?

Oh, sorry about this - I forgot all about it and went on vacation...

Anyway, thanks for all the debugging! I have some more questions, that didn't quite clear things up for me.

1. Which user is running all of this on the vagrant VM? I'm assuming the vagrant user? Can you log in as that user and touch a file in the c3tmp folder, or do you get the same error? What if you try to touch that specific file?
2. On the third question I posted earlier, the last "ls -l" on the vagrant VM, not the host (sorry I didn't make that clear). What do you see then?

Hi @austintino ,
you can sudo as your webserver/php process user and try to create, edit and save file /var/www/phpapps/api.testurl.test/tests/_output/c3tmp/codecoverage.serialized
`
su www-data -s /bin/bash

vi /var/www/phpapps/api.testurl.test/tests/_output/c3tmp/codecoverage.serialized

i new text

[ESC]:qw

ls -al /var/www/phpapps/api.testurl.test/tests/_output/c3tmp/
`
then you will know where to continue with your issue investigation.
