[parted-devel] parted port to FreeBSD

[Viktor Vasilev]

Hello,

Robert Millan and I are working on a port of GNU parted to FreeBSD and 
Debian GNU/kFreeBSD. A patch against trunk is attached, also available from

  http://0xdeadc0de.net/v/parted/parted-trunk-p4.diff

It was tested on FreeBSD 5.4 and 6.0, and also Debian GNU/kFreeBSD 5.x. I 
hope to give the test suite a run this weekend.

Here is some commentary to the changes:

- configure with --disable-dynamic-loading --disable-nls. The latter because 
of missing wide char functions (wcscasecmp, wcsncasecmp and wcsdup).

- disable sigaction, since parts of ui.c contain linux-specific code.

- conditional include of wchar.h in strlist.h, the same way it's done in 
table.c.

- implement strnlen in table.c, as this function is missing on FreeBSD. 

- a weird screen corruption bug in table.c:table_render_row():

  Breakpoint 1, table_render_row (t=0x806a890, rownum=1, ncols=7,
  s=0xbfbfeb24) at table.c:186
  186             wchar_t** row = t->rows[rownum];
  (gdb) watch *s
  Hardware watchpoint 2: *s
  (gdb) n
  187             int len = 1, i;
  ...
  199             *s = realloc (*s, newsize);
  (gdb)
  Hardware watchpoint 2: *s

  Old value = 0x80565a0 "Number   Start   End   Size   Type   File system   
  Flags \n"
  New value = 0x805fe80 "Number   Start   End   Size   
  Tyf1À°\1779E\004\177\003\213E\004)E\004f\001\005Ç\004\020"

The ptr arg to realloc has obviously changed. I don't know what the propper 
fix is.

- Some of the code in freebsd.c comes from various FreeBSD utils. Maybe it 
should be rewritten so it can be GPL'ed?


If you have any comments and suggestions I'll be happy to hear them.


Cheers,
Vik
