---|
3 | |
---|
4 | - subroutines for handling forking/pthreads/etc. |
---|
5 | |
---|
6 | |
---|
7 | 01/20/2006 |
---|
8 | - replaced partimagehack with ntfsclone |
---|
9 | |
---|
10 | 06/20/2004 |
---|
11 | - create fifo /var/log/partimagehack-debug.log and empty it |
---|
12 | to keep ramdisk from filling up |
---|
13 | |
---|
14 | 04/13/2004 |
---|
15 | - >= should be <= g_loglevel |
---|
16 | |
---|
17 | 11/15/2003 |
---|
18 | - changed a few []s to char*s |
---|
19 | |
---|
20 | 10/12 |
---|
21 | - rewrote partimagehack handling (multiple fifos, chunks, etc.) |
---|
22 | |
---|
23 | 10/11 |
---|
24 | - partimagehack now has debug level of N (set in my-stuff.h) |
---|
25 | |
---|
26 | 10/08 |
---|
27 | - call to partimagehack when restoring will now log errors to /var/log/....log |
---|
28 | |
---|
29 | 10/06 |
---|
30 | - cleaned up logging a bit |
---|
31 | |
---|
32 | 09/30 |
---|
33 | - line 735 - missing char* cmd in sprintf() |
---|
34 | |
---|
35 | 09/28 |
---|
36 | - added run_external_binary_with_percentage_indicator() |
---|
37 | - rewritten eval_call_to_make_ISO() |
---|
38 | |
---|
39 | 09/18 |
---|
40 | - call mkstemp instead of mktemp |
---|
41 | |
---|
42 | 09/13 |
---|
43 | - major NTFS hackage |
---|
44 | |
---|
45 | 09/12 |
---|
46 | - paranoid_system("rm -f /tmp/ *PARTIMAGE*") before calling partimagehack |
---|
47 | |
---|
48 | 09/11 |
---|
49 | - forward-ported unbroken feed_*_partimage() subroutines |
---|
50 | from early August 2003 |
---|
51 | |
---|
52 | 09/08 |
---|
53 | - detect & use partimagehack if it exists |
---|
54 | |
---|
55 | 09/05 |
---|
56 | - finally finished partimagehack hack :) |
---|
57 | |
---|
58 | 07/04 |
---|
59 | - added subroutines to wrap around partimagehack |
---|
60 | |
---|
61 | 04/27 |
---|
62 | - don't echo (...res=%d...) at end of log_it() |
---|
63 | unnecessarily |
---|
64 | - replace newtFinished() and newtInit() with |
---|
65 | newtSuspend() and newtResume() |
---|
66 | |
---|
67 | 04/24 |
---|
68 | - added some assert()'s and log_OS_error()'s |
---|
69 | |
---|
70 | 04/09 |
---|
71 | - cleaned up run_program_and_log_output() |
---|
72 | |
---|
73 | 04/07 |
---|
74 | - cleaned up code a bit |
---|
75 | - let run_program_and_log_output() accept -1 (only log if _no error_) |
---|
76 | |
---|
77 | 01/02/2003 |
---|
78 | - in eval_call_to_make_ISO(), append output to MONDO_LOGFILE |
---|
79 | instead of a temporary stderr text file |
---|
80 | |
---|
81 | 12/10 |
---|
82 | - patch by Heiko Schlittermann to handle % chars in issue.net |
---|
83 | |
---|
84 | 11/18 |
---|
85 | - if mkisofs in eval_call_to_make_ISO() returns an error then return it, |
---|
86 | whether ISO was created or not |
---|
87 | |
---|
88 | 10/30 |
---|
89 | - if mkisofs in eval_call_to_make_ISO() returns an error then find out if |
---|
90 | the output (ISO) file has been created; if it has then return 0 anyway |
---|
91 | |
---|
92 | 08/01 - 09/30 |
---|
93 | - run_program_and_log_output() now takes boolean operator to specify |
---|
94 | whether it will log its activities in the event of _success_ |
---|
95 | - system() now includes 2>/dev/null |
---|
96 | - enlarged some tmp[]'s |
---|
97 | - added run_program_and_log_to_screen() and run_program_and_log_output() |
---|
98 | |
---|
99 | 07/24 |
---|
100 | - created |
