otherwise, biggiefile not found & checksum missing & so on - exclude "incheckentry xwait()" from changed.files - cleaned up some log_it() calls 07/01 - 07/31 - renamed libmondo-verify.c - say 'bigfile' not 'biggiefile' - exclude /dev/ * from changed.files 01/01 - 06/30 - remove /tmp/changed.files.* dead files - don't pclose() tape after calling closein_tape(): the latter does it already - fixed bug in verify_cd_image()'s CD-mounting code - don't write to screen "old cksum.. curr cksum.." - changed the gawks to awks for the benefit of Debian - handles files >2GB in size - fixed bug in /tmp/changed.files-generator - re-enabled a lot of CD-verification code - afioballs are saved in %s/tmpfs/ now (%s=tmpdir) - changed some labels to make them more user-friendly - don't chdir() anywhere before verifying stuff - changed files are now detected by verify_tape_backup() and listed in /tmp/changed.files - replaced &> with > .. 2> - still implementing improved tape support Started late Dec, 2001 ----------------------------------------------------------------------------- */ /** * @file * Functions for verifying backups (booted from hard drive, not CD). */ #include "my-stuff.h" #include "mondostructures.h" #include "libmondo-verify.h" #include "libmondo-gui-EXT.h" #include "libmondo-files-EXT.h" #include "libmondo-fork-EXT.h" #include "libmondo-stream-EXT.h" #include "libmondo-string-EXT.h" #include "libmondo-devices-EXT.h" #include "libmondo-tools-EXT.h" #include "lib-common-externs.h" /*@unused@*/ //static char cvsid[] = "$Id: libmondo-verify.c 1316 2007-04-16 14:50:28Z bruno $";
