3 | |
---|
4 | - for subroutines which manipulate the filelist |
---|
5 | |
---|
6 | |
---|
7 | 01/11/2005 |
---|
8 | - change time_of_last_full_backup = to st_mtime to allow manipulation of |
---|
9 | - /var/cache/mondo-archive/difflevel.0 |
---|
10 | - Conor Daly <conor.daly@met.ie> |
---|
11 | |
---|
12 | 10/01 |
---|
13 | - don't try to sort non-existent file; return 0 instead |
---|
14 | |
---|
15 | 09/14 |
---|
16 | - dropped 'sort -o' (busybox doesn't support); use 'sort > ' instead |
---|
17 | |
---|
18 | 08/02 |
---|
19 | - add \ in front of [, ], ? or * when generating filelist subset |
---|
20 | |
---|
21 | 07/27 |
---|
22 | - sort filelists after creating them |
---|
23 | |
---|
24 | 07/14 |
---|
25 | - disabled ACL, xattr stuff; moved it to libmondo-archive.c |
---|
26 | - max sane size for a file is now 32MB |
---|
27 | |
---|
28 | 07/10 |
---|
29 | - added ACL and xattr support for afio users |
---|
30 | |
---|
31 | 07/05 |
---|
32 | - exclude /dev/shm from backup (Roberto Alsina) |
---|
33 | |
---|
34 | 06/09 |
---|
35 | - exclude /media/floppy or SuSE 9.1 freezes :( |
---|
36 | |
---|
37 | 01/18/2004 |
---|
38 | - exclude /sys as well as /proc |
---|
39 | |
---|
40 | 10/18/2003 |
---|
41 | - load_filelist() --- make sure you add the paths |
---|
42 | leading to the file, e.g. if you add /usr/lib/thingy.so |
---|
43 | then add /usr, /usr/lib first |
---|
44 | - rewritten load_filelist(), save_filelist(), |
---|
45 | - add_string_at_node(), find_string_at_node(), |
---|
46 | - save_filelist_entries_in_common() |
---|
47 | |
---|
48 | 09/27 |
---|
49 | - line 1269 had one too many '%s's |
---|
50 | |
---|
51 | 09/26 |
---|
52 | - fix newt* to be enclosed in #ifndef _XWIN |
---|
53 | - added superior progress display to mondo_makefilelist() |
---|
54 | |
---|
55 | 09/18 |
---|
56 | - call locate w/ 2> /dev/null at end of str |
---|
57 | |
---|
58 | 09/16 |
---|
59 | - replaced mondo-makefilelist with C subroutine |
---|
60 | |
---|
61 | 06/06 |
---|
62 | - fixed silly bug in load_filelist() which stopped |
---|
63 | funny German filenames from being handled properly |
---|
64 | |
---|
65 | 05/19 |
---|
66 | - misc clean-up (Steve Hindle) |
---|
67 | |
---|
68 | 05/04 |
---|
69 | - added Herman Kuster's multi-level bkp patch |
---|
70 | |
---|
71 | 04/26 |
---|
72 | - maximum max_set_size_for_a_file = maxsetsizeK*2 |
---|
73 | - maximum is also 32MB |
---|
74 | |
---|
75 | 04/24 |
---|
76 | - added lots of assert()'s and log_OS_error()'s |
---|
77 | |
---|
78 | 04/22 |
---|
79 | - added lots of asserts() and log_OS_errors()'s |
---|
80 | |
---|
81 | 04/07 |
---|
82 | - cleaned up code a bit |
---|
83 | |
---|
84 | 04/04 |
---|
85 | - max_sane_size_for_a_file = maxsetsizeK*2 (was *8) |
---|
86 | |
---|
87 | 01/02/2003 |
---|
88 | - tell mondo-makefilelist that it's a custom catalog (if it is) |
---|
89 | |
---|
90 | 10/01 - 10/31/2002 |
---|
91 | - don't make large .bz2 or .tbz files into biggiefiles |
---|
92 | - max_sane_size_for_a_file = maxsetsizeK*8, or 64MB |
---|
93 | ...whichever is smaller |
---|
94 | |
---|
95 | 08/01 - 08/31 |
---|
96 | - if last filelist is <=2 bytes long then delete it |
---|
97 | - max_sane_size_for_a_file = maxsetsizeK |
---|
98 | (was SLICESIZE*4 or something) |
---|
99 | - cleaned up some log_it() calls |
---|
100 | |
---|
101 | 07/26 |
---|
102 | - started |
