23 | |
---|
24 | 07/07 |
---|
25 | - added star verify support |
---|
26 | |
---|
27 | 04/04/2004 |
---|
28 | - added star support |
---|
29 | |
---|
30 | 10/23/2003 |
---|
31 | - changed "ISO #n" to "<media descriptor> #n" |
---|
32 | |
---|
33 | 10/01 |
---|
34 | - working on biggiefile verification (CDs) |
---|
35 | |
---|
36 | 09/16 |
---|
37 | - fixed bug in CD biggie verif'n |
---|
38 | |
---|
39 | 09/15 |
---|
40 | - state explicitly that we do not verify disk images |
---|
41 | |
---|
42 | 09/13 |
---|
43 | - working on verify_all_slices_on_CD() |
---|
44 | |
---|
45 | 09/01 |
---|
46 | - write list of changed biggiefiles (streaming only) to changed.files |
---|
47 | |
---|
48 | 05/05 |
---|
49 | - exclude /dev/ * from list of changed files |
---|
50 | - add Joshua Oreman's FreeBSD patches |
---|
51 | |
---|
52 | 04/24/2003 |
---|
53 | - added lots of assert()'s and log_OS_error()'s |
---|
54 | |
---|
55 | 09/01 - 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 | |
---|
61 | 08/01 - 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 | |
---|
68 | 07/01 - 07/31 |
---|
69 | - renamed libmondo-verify.c |
---|
70 | - say 'bigfile' not 'biggiefile' |
---|
71 | - exclude /dev/ * from changed.files |
---|
72 | |
---|
73 | 01/01 - 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 |
---|
89 | |
