3
4- for subroutines which manipulate the filelist
5
6
701/11/2005
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
1210/01
13- don't try to sort non-existent file; return 0 instead
14
1509/14
16- dropped 'sort -o' (busybox doesn't support); use 'sort > ' instead
17
1808/02
19- add \ in front of [, ], ? or * when generating filelist subset
20
2107/27
22- sort filelists after creating them
23
2407/14
25- disabled ACL, xattr stuff; moved it to libmondo-archive.c
26- max sane size for a file is now 32MB
27
2807/10
29- added ACL and xattr support for afio users
30
3107/05
32- exclude /dev/shm from backup (Roberto Alsina)
33
3406/09
35- exclude /media/floppy or SuSE 9.1 freezes :(
36
3701/18/2004
38- exclude /sys as well as /proc
39
4010/18/2003
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
4809/27
49- line 1269 had one too many '%s's
50
5109/26
52- fix newt* to be enclosed in #ifndef _XWIN
53- added superior progress display to mondo_makefilelist()
54
5509/18
56- call locate w/ 2> /dev/null at end of str
57
5809/16
59- replaced mondo-makefilelist with C subroutine
60
6106/06
62- fixed silly bug in load_filelist() which stopped
63 funny German filenames from being handled properly
64
6505/19
66- misc clean-up (Steve Hindle)
67
6805/04
69- added Herman Kuster's multi-level bkp patch
70
7104/26
72- maximum max_set_size_for_a_file = maxsetsizeK*2
73- maximum is also 32MB
74
7504/24
76- added lots of assert()'s and log_OS_error()'s
77
7804/22
79- added lots of asserts() and log_OS_errors()'s
80
8104/07
82- cleaned up code a bit
83
8404/04
85- max_sane_size_for_a_file = maxsetsizeK*2 (was *8)
86
8701/02/2003
88- tell mondo-makefilelist that it's a custom catalog (if it is)
89
9010/01 - 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
9508/01 - 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
10107/26
102- started
