Message: Logged In: YES user_id=421 Currently we only handle exits through pdf_fail. But we also need to trap other exits; this must be done through atexit(3). ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2005-12-19 00:38 Message: Logged In: YES user_id=421 The attached patch unlinks the current file, if a fatal error happens. Currently this is done without any checks, and may be a security problem. ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2004-07-02 14:35 Message: Logged In: YES user_id=1608 When you truncate a file, the result is an empty file. From a user's viewpoint, that is not the same thing as a corrupt PDF. The distinction is small, but the advantage of an empty file is that it is not likely to be confused for a correct PDF. If it is possible, then deleting the PDF file is definately better, but file deletion doesn't always work. Truncation almost always does work, and it's only two syscalls extra, so why not? ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2004-07-02 14:21 Message: Logged In: YES user_id=421 Simply truncating a pdf still makes it invalid (because the file structure is incomplete). Producing a valid truncated output file in case of fatal errors will be tricky and not always possible. Deleting the corrupt output is much easier. ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2004-07-02 13:50 Message: Logged In: YES user_id=1608 If deleting the file doesnt work, truncation is probably still better than nothing.
