[1] | 3 |
|
---|
| 4 | - subroutines for handling forking/pthreads/etc.
|
---|
| 5 |
|
---|
| 6 |
|
---|
[296] | 7 | 01/20/2006
|
---|
| 8 | - replaced partimagehack with ntfsclone
|
---|
| 9 |
|
---|
[1] | 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
|
---|

---|
| 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
