/* libmondo-archive.c $Id: libmondo-archive.c 1317 2007-04-16 16:26:55Z bruno $ 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] */ /** * @file * Functions to handle backing up data. * This is the main file (at least the longest one) in libmondo. */ #include "my-stuff.h" #include "mondostructures.h" #include "libmondo-string-EXT.h" #include "libmondo-stream-EXT.h" #include "libmondo-devices-EXT.h" #include "libmondo-tools-EXT.h" #include "libmondo-gui-EXT.h" #include "libmondo-fork-EXT.h" #include "libmondo-files-EXT.h" #include "libmondo-filelist-EXT.h" #include "libmondo-tools-EXT.h" #include "libmondo-verify-EXT.h" #include "libmondo-archive.h" #include "lib-common-externs.h" #include #include #include #include #define DVDRWFORMAT 1 /** @def DEFAULT_1722MB_DISK The default 1.722M floppy disk to write images to. */ /** @def BACKUP_1722MB_DISK The 1.722M floppy disk to try if the default fails. */ #ifdef __FreeBSD__ #define DEFAULT_1722MB_DISK "/dev/fd0.1722" #define BACKUP_1722MB_DISK "/dev/fd0.1722" #else #define DEFAULT_1722MB_DISK "/dev/fd0u1722" #define BACKUP_1722MB_DISK "/dev/fd0H1722" #ifndef _SEMUN_H #define _SEMUN_H /** * The semaphore union, provided only in case the user's system doesn't. */ union semun { int val;
