subroutines to handle the archiving of files



07/14
- moved all ACL, xattr stuff here from libmondo-filelist.c

07/12
- when trying to find boot loader, look for /boot's /dev, not just /'s dev

07/10
- better detection of changed files
- added ACL, xattr support for afio

06/17
- backup with partimagehack if NTFS device; dd, if non-NTFS device

06/14
- use mondorescue.iso instead of mindi.iso

04/28
- cleaned up if/then architecture-specific stuff re: CD-R(W)s

04/03
- added star support

03/12
- modified offer_to_write_floppies() to support dual-disk boot/root thing

01/20/2004
- reformat dvd twice if necessary

12/01/2003
- added pause_for_N_seconds(5, "Letting DVD drive settle");

11/23
- added #define DVDRWFORMAT

11/20
- use --no-emul-boot -b isolinux.bin instead of -b mindi-boot.2880.img

10/23
- wipe DVD at start, whether or not disk is DVD-RW; this is
  just a test, to see why dvd+rw-format followed by growiosfs
  locks up the drive
- use the singlethreaded make_afioballs_and_images_OLD()
  instead of the multithreaded make_afioballs_and_images()
  if backing up to tape

10/21
- if backing up to dvd, look for relevant tools;
  abort if missing

10/15
- UI tweaks

10/10
- eject/inject DVD after wiping it

09/27
- pause_and_ask_for_cdr() will now blank DVD if necessary

09/26
- proper reporting of media type in displayed strings
  (i.e. DVD if DVD, CD if CD, etc.)
  
09/25
- add DVD support

09/23
- malloc/free global strings in new subroutines - malloc_libmondo_global_strings()
  and free_libmondo_global_strings() - which are in libmondo-tools.c

09/15
- changed a bunch of char[MAX_STR_LEN]'s to char*; malloc; free;

09/14
- cosmetic bug re: call to 'which dvdrecord'

09/09
- copy `locate isolinux.bin | tail -n1` to CD before calling mkisfso
  if file is missing (in which case, bug in Mindi.pl!)
- reduced noof_threads from 3 to 2
- fixed cosmetic bug in make_slices_and_images()

09/02
- fixed cosmetic bug in verify_data()

05/01 - 08/31
- added partimagehack hooks
- make twice as many archives at once as before 
- fixed syntax error re: system(xxx,FALSE)
- unmount CD-ROM before burning (necessary for RH8/9)
- only ask for new media if sensible
- fixed mondoarchive -Vi multi-CD verify bug (Tom Mortell)
- use single-threaded make_afioballs_and_images() if FreeBSD
- fixed bug on line 476 (Joshua Oreman)
- re-enabled the pause, for people w/ weird CD-ROM drives
- added Joshua Oreman's FreeBSD patches
- don't listen to please_dont_eject_when_restoring
  ...after all, we're not restoring :)

04/01 - 04/30
- cleaned up archive_this_fileset()
- decreased ARCH_THREADS from 3 to 2
- pause_and_ask_for_cd() --- calls retract_CD_tray_and_defeat_autorun()
- call assert() and log_OS_error() in various places
- cleaned up code a bit
- increased ARCH_THREADS from 2 to 3
- misc clean-up (Tom Mortell)

03/15/2003
- fixed problem w/ multi-ISO verify cycle (Tom Mortell)

11/01 - 12/31/2002
- removed references to make_afioballs_and_images_OLD()
- added some error-checking to make_afioballs_in_background
- make_iso_and_go_on() now copies Mondo's autorun file to CD
- set scratchdir dir to 1744 when burning CD
- cleaned up code a bit
- in call_mindi_...(), gracefully handle the user's input
  if they specify the boot loader but not the boot device
- offer to abort if GRUB is boot loader and /dev/md* is
  the boot device (bug in grub-install)
- if boot loader is R then write RAW as bootloader.name
- multithreaded make_afioballs_and_images()
- fixed slice_up_file_etc() for 0-compression users
- line 1198: added call to is_this_file_compressed() to stop
  slice_up_file_etc() from compressing files which are
  already compressed
- other hackery related to the above enhancement
- afio no longer forcibly compresses all files (i.e. I dropped
  the -U following suggestions from users); let's see if
  it works :)

10/01 - 10/31
- mondoarchive (with no parameters) wasn't working
  if user said yes when asked if BurnProof drive; FIXED
- if manual CD tray and writing to ISO's then prompt
  for each & every new CD
- moved a lot of subroutines here
  from mondo-archive.c and mondo-floppies.c

09/01 - 09/30
- if CD not burned OK then don't try to verify
- change 64k to TAPE_BLOCK_SIZE
- run_program_and_log_output() now takes boolean operator to specify
  whether it will log its activities in the event of _success_
- orig_vfy_flag_val added to write_iso_and_go_on, to restore bkpinfo->verify_data's
  value if altered by verify_cd_image()

08/01 - 08/31
- use data structure to store the fname, checksum, mods & perms of each bigfile
  ... biggiestruct :)
- bigger tmp[]'s in a few places
- cleaned up the (user-friendly) counting of biggiefiles a bit
- if media_size[N]<=0 then catch it & abort, unless it's tape,
  in which case, allow it
- cleaned up a lot of log_it() calls
- fixed NULL filename-related bug in can_we_fit_these_files_on_media()
- deleted can_we_fit.....() subroutine because it was causing problems
  --- moved its code into the one subroutine which called it
- created [08/01/2002]
