* removing unneeded casts of void* return values
* replacing varied and creative error messages with the allocation
function's name
* replacing errx() with err() so that the errno string is reported
ok beck@, jung@, millert@
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms
- remove quite some code, use strcasestr instead of reimplementing
it each time
- use strncasecmp, instead of comparing through each character
"looks fine" millert@
o Style nits
o Use const to silent stupid -Wall warnings
o strnc{py,at} -> strlc{py,at}
o Use strpbrk() instead of homegrown anyof()
o Use NULL instead of #defines with 0 cast to a pointer
This still could use a proper audit
o escape From line with a leading '>' when needed
o only print To: address and Subject lines if actually present
o new variable 'allnet' to treat user@foo and user@bar as the same "user"
o folders command now takes an optional argument like ls.
o new "pipe" (|) command to pipe the message through an arbitrary command
o make header display format the same as SunOS 4.1.3 /usr/ucb/mail
o tilde commands work regardless of interactive mode.
o fix "read: Interrupted system call" error by retrying if EINTR
o expanded help file
Changes by me:
o read the help file via the PAGER as it is now more than 24 lines long
replace panic() with calls to err()/errx()
use S_IS* instead of doing by hand with S_IF*.
Use TIMESPEC_TO_TIMEVAL() and gettimeofday instead of time(2)
Use _POSIX_VDISABLE, not 0
Kill register
- handle long lines safely (from NetBSD)
- use puts/fputs and putchar/putc when it makes sense
- use err/errx and warn/warnx when it makes sense
- make return() and sizeof() style consisten
- some more buffer safety
