|
---|
| 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 |
