4 | Many people have contributed to cron. Many more than I can remember, in fact. | |
5 | Rich Salz and Carl Gutekunst were each of enormous help to me in V1; Carl for | |
6 | helping me understand UNIX well enough to write it, and Rich for helping me | |
7 | get the features right. | |
8 | ||
9 | John Gilmore wrote me a wonderful review of V2, which took me a whole year to | |
10 | answer even though it made me clean up some really awful things in the code. | |
11 | (According to John the most awful things are still in here, of course.) | |

13 | Paul Close made a suggestion which led to /etc/crond.pid and the mutex locking | |
14 | on it. Kevin Braunsdorf of Purdue made a suggestion that led to @reboot and | |
15 | its brothers and sisters; he also sent some diffs that lead cron toward compil- | |
16 | ability with System V, though without at(1) capabilities, this cron isn't going | |
17 | to be that useful on System V. Bob Alverson fixed a silly bug in the line | |
18 | number counting. Brian Reid made suggestions which led to the run queue and | |
19 | the source-file labelling in installed crontabs. | |

21 | Scott Narveson ported V2 to a Sequent, and sent in the most useful single batch | |
22 | of diffs I got from anybody. Changes attributable to Scott are: | |
23 | -> sendmail won't time out if the command is slow to generate output | |
24 | -> day-of-week names aren't off by one anymore | |
25 | -> crontab says the right thing if you do something you shouldn't do | |
26 | -> crontab(5) man page is longer and more informative | |
27 | -> misc changes related to the side effects of fclose() | |
28 | -> Sequent "universe" support added (may also help on Pyramids) | |
29 | -> null pw_shell is dealt with now; default is /bin/sh |
