|
---|
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
|
---|
