source: MondoRescue/branches/2.2.5/mondo/src/common/libmondo-verify.c @ 1644

Last change on this file since 1644 was 1644, checked in by Bruno Cornec, 12 years ago

Apply patch from Andree Leidenfrost, modified a bit to use bkpinfo->tmpdir instead of /tmp
or MINDI_CACHE when appropriate. Fix security issues in mondo
Thanks al ot Andree for catching all those issues.
Will not compile needs more work as bkpinfo->tmpdir isn't available everywhere
Should become a global in 3.x when only containing pointers.

23
2407/07
25- added star verify support
26
2704/04/2004
28- added star support
29
3010/23/2003
31- changed "ISO #n" to "<media descriptor> #n"
32
3310/01
34- working on biggiefile verification (CDs)
35
3609/16
37- fixed bug in CD biggie verif'n
38
3909/15
40- state explicitly that we do not verify disk images
41
4209/13
43- working on verify_all_slices_on_CD()
44
4509/01
46- write list of changed biggiefiles (streaming only) to changed.files
47
4805/05
49- exclude /dev/ * from list of changed files
50- add Joshua Oreman's FreeBSD patches
51
5204/24/2003
53- added lots of assert()'s and log_OS_error()'s
54
5509/01 - 09/30/2002
56- run_program_and_log_output() now takes boolean operator to specify
57  whether it will log its activities in the event of _success_
58- eject_device() added
59- cleaned up 'changed file' feedback a little bit
60
6108/01 - 08/31
62- make sure to prefix bkpinfo->restore_path to local biggiefile fname when
63  comparing it to the archived copy of biggiefile; otherwise, biggiefile
64  not found & checksum missing & so on
65- exclude "incheckentry xwait()" from changed.files
66- cleaned up some log_it() calls
67
6807/01 - 07/31
69- renamed libmondo-verify.c
70- say 'bigfile' not 'biggiefile'
71- exclude /dev/ * from changed.files
72
7301/01 - 06/30
74- remove /tmp/changed.files.* dead files
75- don't pclose() tape after calling closein_tape(): the latter does it already
76- fixed bug in verify_cd_image()'s CD-mounting code
77- don't write to screen "old cksum.. curr cksum.."
78- changed the gawks to awks for the benefit of Debian
79- handles files >2GB in size
80- fixed bug in /tmp/changed.files-generator
81- re-enabled a lot of CD-verification code
82- afioballs are saved in %s/tmpfs/ now (%s=tmpdir)
83- changed some labels to make them more user-friendly
84- don't chdir() anywhere before verifying stuff
85- changed files are now detected by verify_tape_backup() and listed in
86  /tmp/changed.files
87- replaced &> with > .. 2>
88- still implementing improved tape support
