Hello all, I've been working with the tarfile module and just noticed an apparent flaw in my own logic. I wanted to add files to the tar until it neared a certain file size. After every addition I would use os.path.getsize(). What I noticed today is that I could add a file to the tar without the tar's size changing. I'm assuming that because the TarFile object is not closed, finding its size that way isn't reliable.
The first thing I tried was using flush(), but TarFile objects apparently don't do that. I also can't close the object and reopen it for appending because TarFile objects can't append if the tar is compressed. And finally, I can't predict the compression ratio, so I can't merely keep track of the size of the individual files without a huge gap to my target size. I'm giving up on it for the night. Anyone have any thoughts? Adam _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
