acornfsutils's Issues

afscp coredumps when a directory is full

Full seems to be 47 entries.

Here's a stack trace:

Feature Request: Recursive copy (including directory creation)

My use case is building a ARM Eval Co Pro hard disk image from the six original floppy disks.

Some of the ARM disks contain sub-directories, for example:

$ afstree disc4.adl 
--RW----- 00000000 00000000         15 000007 !boot
D-RW----- 00000000 00000000      1,280 000340 image

As far as I can tell, there is no way to handle this at present with AcornFsUtils, because there is no way to create a new directory on an ADFS destination.

Do you have any thought on this?

I'm happy to do some of the implementation...

I was thinking you would need to:

  1. Add mkdir() and rmdir() to the acorn_fs interface and implement these in acorn-adfs.c
  2. Add a -r (recursive) option to the afscp command
  3. Update the afscp code so that if a directory is encountered in the source list then it is copied recursively to the destination (creating directories as needed)

Even just (1) alone would be useful. I could then at least manually create the required directory structure.
