6 | * Revision 4.5 88/09/19 20:27:49 don |
---|
7 | * bellcore copyright. |
---|
8 | * |
---|
9 | * Revision 4.4 88/06/13 16:27:24 don |
---|
10 | * fixed a bug in device-handling: if device major/minor #'s are wrong, |
---|
11 | * have to delete the node & call mknode(). |
---|
12 | * |
---|
13 | * Revision 4.3 88/06/10 15:55:29 don |
---|
14 | * fixed a bug in device-handling: update was triggered by differences in |
---|
15 | * st_dev, rather than st_rdev. |
---|
16 | * |
---|
17 | * Revision 4.2 88/05/27 20:15:21 don |
---|
18 | * fixed two bugs at once: the nopulflag bug, and -I wasn't preserving |
---|
19 | * mode-bits at all. see update(). |
---|
20 | * |
---|
21 | * Revision 4.1 88/05/25 21:42:09 don |
---|
22 | * added -I option. needs compatible track.h & track.c. |
---|
23 | * |
---|
24 | * Revision 4.0 88/04/14 16:43:30 don |
---|
25 | * this version is not compatible with prior versions. |
---|
26 | * it offers, chiefly, link-exporting, i.e., "->" systax in exception-lists. |
---|
27 | * it also offers sped-up exception-checking, via hash-tables. |
---|
28 | * a bug remains in -nopullflag support: if the entry's to-name top-level |
---|
29 | * dir doesn't exist, update_file doesn't get over it. |
---|
30 | * the fix should be put into the updated() routine, or possibly dec_entry(). |
---|
31 | * |
---|
32 | * Revision 3.0 88/03/09 13:17:18 don |
---|
33 | * this version is incompatible with prior versions. it offers: |
---|
34 | * 1) checksum-handling for regular files, to detect filesystem corruption. |
---|
35 | * 2) more concise & readable "updating" messages & error messages. |
---|
36 | * 3) better update-simulation when nopullflag is set. |
---|
37 | * 4) more support for non-default comparison-files. |
---|
38 | * finally, the "currentness" data-structure has replaced the statbufs |
---|
39 | * used before, so that the notion of currency is more readily extensible. |
---|
40 | * note: the statfile format has been changed. |
---|
41 | * |
---|
42 | * Revision 2.2 88/01/29 18:24:18 don |
---|
43 | * bug fixes. also, now track can update the root. |
---|
44 | * |
---|
45 | * Revision 2.1 87/12/03 17:33:18 don |
---|
46 | * fixed lint warnings. |
---|
47 | * |
---|
48 | * Revision 2.1 87/12/01 20:56:26 don |
---|
49 | * robustified file-updating, so that more failure-checking is done, |
---|
50 | * and so that if either utimes() or set_prots() fails, the other will |
---|
51 | * still run. made double-sure that protections & time don't |
---|
52 | * change, unless copy-file succeeds. |
---|
53 | * |
---|
54 | * Revision 2.0 87/11/30 15:19:35 don |
---|
55 | * general rewrite; got rid of stamp data-type, with its attendant garbage, |
---|
56 | * cleaned up pathname-handling. readstat & writestat now sort overything |
---|
57 | * by pathname, which simplifies traversals/lookup. should be comprehensible |
---|
58 | * now. |
---|
59 | * |
---|
60 | * Revision 1.2 87/09/02 17:44:20 shanzer |
---|
61 | * Aborts if We get a write error when copying a file.. |
---|
62 | * |
---|
63 | * Revision 1.1 87/02/12 21:16:00 rfrench |
---|
64 | * Initial revision |
