Patches for pax

From: Russell Stuart <russell(at)stuart.id.au>
Date: Tue Apr 22 2003 - 01:54:52 EDT


Here is yet another version of some patches I have done to pax. This lot are against the CVS head of a week or so ago. The previous lot were for OpenBSD 3.0.

These patches are mostly add new features - not fix bugs. This does not seem to be the appropriate list to send so things - is there a better one?

This first patch GNU'ises the pax source. Pax uses some C library routines only found on BSD, such as fgetln(). I am not using a BSD platform. I emulated most of those routines in a separate library outside of the pax source. This patch only covers the cases where that was not possible. The changed code should compile on any GNU platform. There are also a couple of bug fixes here to do with handling long (as opposed to long long) off_t's.

----------------------------------------------------------------------

This second patch replaces a patch I sent earlier (on 2003-03-21). The patch adds a -M option that causes pax/cpio/tar to treat files being modified or deleted as they are copied as warning rather than an error. A warning message it still issued, but the exit status remains at 0. The earlier version of the patch did not handle file deletion.

The rational for the patch is that I use pax to backup entire file systems and there are some files that are modified during the copy - typically log files and such. I want those files backed up and I don't care if I miss a few lines at the end, and I don't care they are deleted before pax gets to them (happens during log file rotation). So pax having a non-zero exit status because the file system was modified while during the copy is less than helpful. When the -M flag is given the non-zero exit status is reserved for something really going wrong - like a write error.

There is also a patch in here to make the pax version of cpio behave like the real cpio. The real cpio does not exit immediately if passed a filename on stdin that does not exist. Instead it behaves like pax (when invoked as pax) does - it ignores the problem file and has a non zero exit status. I did this primarily because it makes the rest of the stuff I did easier, but I think it should be behave like that regardless.

Can't find what you're looking for?X
