Returns true if the named file is readable by the effective user and group id of this process. Returns true if the named file is readable by the real user and group id of this process.
Returns the real absolute pathname of pathname in the actual filesystem. The real pathname doesn't contain symlinks or useless dots. Returns the real absolute pathname of pathname in the actual filesystem not containing symlinks or useless dots.
Renames the given file to the new name. Raises a SystemCallError if the file cannot be renamed. Splits the given string into a directory and a file component and returns them in a two-element array. See also File::dirname and File::basename. Raises a NotImplemented exception on platforms that do not support symbolic links. Returns the current umask value for this process. If the optional argument is given, set the umask to that value and return the previous value.
Umask values are subtracted from the default permissions, so a umask of would make a file read-only for everyone. If a file is a symlink, this method acts upon its referent rather than the link itself; for the inverse behavior see File.
Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat 2. Returns true if the named file is writable by the effective user and group id of this process. Returns true if the named file is writable by the real user and group id of this process. Returns the last access time a Time object for file , or epoch if file has not been accessed. Actual effects are platform dependent; on Unix systems, see chmod 2 for details.
Follows symbolic links. Also see File lchmod. Changes the owner and group of file to the given numeric owner and group id's. See also File lchown. Returns the change time for file that is, the time directory information about the file was changed, not the file itself. Same as IO stat , but does not follow the last symbolic link. The pathname may not point to the file corresponding to file. For instance, the pathname becomes void when the file has been moved or deleted.
Truncates file to at most integer bytes. The file must be opened for writing. Home Core 2. Home Classes Methods. In Files dir. Parent IO. I'm not entirely sure what would be causing the problem that martinstreicher is seeing, but I would have to ask to make sure that Paperclip and Cocaine are up to date and try to confirm the problem still exists.
Seems problem still exists. If pass already closed Tempfile then raises "IOError: closed stream". I just rewrite my code to file closing after, but maybe we should mention about closed file in documentation or reopen file.
ASnow , please, can you post your code? I restarted my server and browser. If it happens again, I'll come back and ask for more help.
Otherwise, thank you! Sorry about this problem, all. I've pushed 3. It should help. If not, please let me know in a new issue, preferably, so I can close this for bookkeeping purposes.
Sorry I don't have time right this second to create a simple reproducible case or open a new issue but I thought I should at least let you know.
In my app, reverting to 3. It appears the newer versions of paperclip assume that processors return an entirely new file, which is why the original file handle gets closed.
The history of this seems to be here and here. So the solution for this is to ensure that if you have custom processor that it always returns a new file?
I have processors that read from the original file just to extract meta data but don't alter the file in any way. It seems a little pointless to generate a new file in this instance.
I assume I'd have to do the same as above, even if it's a 5Gb video file for example. I am on paperclip v5. However, I believe I can shed some light on why it happens In my case, I found that I would only see the IO stream closed stacktrace when using a custom processor e. If I removed the processor definition I would no longer see the error. I believe that is because When trying to process a kind of file that is unknown to the processor, it seems to simply close the stream. For example, if I try to upload a video file for an attachment that is intended to be an image, I saw the closed stream stacktrace.
If you really need to open the file outside your backup method, I think what you need at the end of bakcup is f. This would be an acceptable solution for you provided that you don't open hundreds of files in your script. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
