[1] | 3 |
|
---|
| 4 | ...tools for talking to tapes, Monitas streams, etc.
|
---|
| 5 |
|
---|
| 6 |
|
---|
| 7 | 07/10
|
---|
| 8 | - added ACL and XATTR support
|
---|
| 9 |
|
---|
| 10 | 04/17
|
---|
| 11 | - added bkpinfo->internal_tape_block_size
|
---|
| 12 | - fixed bug in set_tape_block_size_with_mt()
|
---|
| 13 |
|
---|
| 14 | 03/25
|
---|
| 15 | - call 'mt' when opening tape in/out, to set block size to 32K
|
---|
| 16 |
|
---|
| 17 | 02/06/2004
|
---|
| 18 | - only eject_device() at end of closein_tape() --- not closeout_tape()
|
---|
| 19 |
|
---|
| 20 | 10/26/2003
|
---|
| 21 | - call eject_device() at end of closein_tape() and closeout_tape()
|
---|
| 22 |
|
---|
| 23 | 09/25
|
---|
| 24 | - added docu-header to each subroutine
|
---|
| 25 |
|
---|
| 26 | 09/20
|
---|
| 27 | - working on multi-tape code
|
---|
| 28 | - friendlier message in insist_on_this_tape_number()
|
---|
| 29 | - delay is now 5s
|
---|
| 30 |
|
---|
| 31 | 09/10
|
---|
| 32 | - adding multi-tape support
|
---|
| 33 | - adding 'back catalog' of previous archives, so that we may resume
|
---|
| 34 | from point of end-of-tape (approx.)
|
---|
| 35 |
|
---|
| 36 | 09/08
|
---|
| 37 | - cleaned up insist_on_this_tape_number() --- 10s delay for same tape now
|
---|
| 38 |
|
---|
| 39 | 08/27
|
---|
| 40 | - improved find_tape_device_and_size() --- tries /dev/osst*
|
---|
| 41 |
|
---|
| 42 | 05/05
|
---|
| 43 | - added Joshua Oreman's FreeBSD patches
|
---|
| 44 |
|
---|
| 45 | 04/24
|
---|
| 46 | - added lots of assert()'s and log_OS_error()'s
|
---|
| 47 |
|
---|
| 48 | 04/06/2003
|
---|
| 49 | - use find_home_of_exe() instead of which
|
---|
| 50 |
|
---|
| 51 | 12/13/2002
|
---|
| 52 | - cdrecord -scanbus call was missing 2> /dev/null
|
---|
| 53 |
|
---|
| 54 | 11/24
|
---|
| 55 | - disabled fatal_error("Bad marker")
|
---|
| 56 |
|
---|
| 57 | 10/29
|
---|
| 58 | - replaced convoluted grep wih wc (KP)
|
---|
| 59 |
|
---|
| 60 | 09/07
|
---|
| 61 | - removed g_end_of_tape_reached
|
---|
| 62 | - lots of multitape-related fixes
|
---|
| 63 |
|
---|
| 64 | 08/01 - 08/31
|
---|
| 65 | - write 16MB of zeroes to end of tape when closing(out)
|
---|
| 66 | - compensate for 'buffer' and its distortion of speed of writing/reading
|
---|
| 67 | when writing/reading data disks at start of tape
|
---|
| 68 | - rewrote lots of multitape stuff
|
---|
| 69 | - wrote workaround to allow >2GB of archives w/buffering
|
---|
| 70 | - do not close/reopen tape when starting to read/write from
|
---|
| 71 | new tape: no need! 'buffer' handles all that; we're writing
|
---|
| 72 | to/reading from a FIFO, so no need to close/reopen when new tape
|
---|
| 73 | - write 8MB of zeroes at end of tape, just in case
|
---|
| 74 | - re-enable various calls to *_evalcall_form
|
---|
| 75 | - added g_end_of_tape_reached
|
---|
| 76 | - fixed bugs in start_to_[read|write]_[to|from]_next_tape
|
---|
| 77 | - added internal buffering, replacing the external 'buffer' exe
|
---|
| 78 | - wait 10 seconds (after user inserts new tape), to
|
---|
| 79 | let tape stabilize in drive
|
---|
| 80 | - added insist_on_this_tape_number()
|
---|
| 81 | - worked on find_tape_device_and_size()
|
---|
| 82 | - cleaned up some log_it() calls
|
---|
| 83 | - added find_tape_device_and_size()
|
---|
| 84 | - replaced using_cdstream with backup_media_type
|
---|
| 85 | - replace *_from_tape with *_from_stream
|
---|
| 86 | - replace *_to_stream with *_to_stream
|
---|
| 87 |
|
---|
| 88 | 07/01 - 07/31
|
---|
| 89 | - leave 32MB at end of tape, to avoid overrunning
|
---|
| 90 | - started [07/24/2002]
