I have a process that fetches a file, then moves it (overwriting if already exists). The copy part fails, and I cannot determine why.
Here is some PHP I am using to reproduce the issue I am seeing (with output functions from Devel module):
$source = 'temporary://someFile';
$destination = 'public://profile_pictures/someFile.jpg';
# Get name of Linux user running this
$username = posix_getpwuid(posix_geteuid())('name');
dpm($username); # nginx
dvm(file_exists($source)); # TRUE
dvm(file_exists($destination)); # TRUE
# File permissions
dpm(substr(sprintf('%o', fileperms($source)), -4)); # 0600
dpm(substr(sprintf('%o', fileperms($destination)), -4)); # 0644
# Try Drupal's copy
$r = file_unmanaged_copy($source, $destination, FILE_EXISTS_REPLACE);
dvm($r); # FALSE
# Try PHP copy that Drupal uses internally, to see the error
dvm(copy($destination, $source)); # TRUE ( Copy backwards works... )
dvm(copy($source, $destination)); # FALSE ( But this doesn't work. )
The last line gives the following error:
Warning: copy(public://profile_pictures/someFile.jpg): failed to open stream: “DrupalPublicStreamWrapper::stream_open”
So copying backwards works, but it won’t copy from temporary:// to profile_pictures. Also, if I delete public://profile_pictures/someFile.jpg first, then it works.
Permissions of files and folders:
drwxrwx--- www-data www-data temporary://
-rw------- nginx nginx temporary://someFile
drwxrwxr-x www-data www-data public://profile_pictures
-rw-rw-r-- nginx nginx public://profile_pictures/someFile.jpg
The temporary directory is a sub-folder of public://. The nginx user is in the www-data group.
Is this a permissions issue? Looking at Drupal’s requirements, I don’t see what I am doing wrong.
