2016-09-01In 32 bits sqrt(val) + 1 can overflow, so some big primes stillTheo Buehler
aren't recognized as such, for example 18446744073709551577 given in the commit message of factor.c r1.7 from NetBSD. Move the return type of usqrt() from u_int32_t to u_int64_t. ok guenther, tom, otto
2016-08-31Fix a bogus comment: "factors of" -> "coprime to". Replace theTheo Buehler
nonsensical "if and only iff" with "if and only if" and zap some trailing whitespace.
2016-08-27the quotes in "unkempt thoughts" were authored by stanislaw lec,Jason McIntyre
not stanislaw lem (an easy blunder, i'd say); i've also inserted the "J." into one of these credits (Stanislaw J. Lec) since all the others have them; credit to antoni grzymala; diff pockled from netbsd

2016-08-14Convert remaining calls to strtoq/strtouq in base with strtoll/strtoull.Philip Guenther
Fix a type mismatch in ftp's "page" command and could make transfers restart at the wrong position. ok and a ull->ll tweak from natano@, ok tedu@
2016-07-11Instead of using the floating point square root, use an integer versionTheo Buehler
of the Newton method from ping.c. Fixes a rounding issue that caused failure to factor numbers close to 2^64, e.g. 18446744030759878681. While there, fix an off by one error that caused 4295360521 to be reported as a prime. Issues reported by Paul Stoeber and Michael Bozon. ok tedu, deraadt
2016-06-10Clean up gcc -Wshadow warnings: 'numnames' is public in <term.h>.Theo Buehler
'i' shadows the local loop indexing variable of scr_update(), so no need to rename it. No binary change on amd64. ok millert
2016-06-10When eliding a row, clear the invisible row zero, so that no columnsTheo Buehler
can become unusable during game play. Same fix was made in NetBSD's tetris.c -r1.31 by Christos Zoulas almost exactly a year ago. ok tedu
2016-03-30for some time now mandoc has not required MLINKS to functionJason McIntyre
correctly - logically complete that now by removing MLINKS from base; authors need only to ensure there is an entry in NAME for any function/ util being added. MLINKS will still work, and remain for perl to ease upgrades; ok nicm (curses) bcook (ssl) ok schwarze, who provided a lot of feedback and assistance ok tb natano jung

2016-03-21Instead of creating a socket with socket() or accept() and thenPhilip Guenther
setting the O_NONBLOCK flag on it with fcntl(F_SETFL) afterwards, just pass SOCK_NONBLOCK to socket() or accept4() and get it right to begin with. ok millert@ krw@ beck@ deraadt@ jca@
2016-03-16Prefer fseek(3) over rewind(3) since the latter although it also calls fseekmestre
then additionally it calls clearerr(3) deliberately but we want to catch any error that may happen and this way we couldn't catch it OK tb@
2016-03-15execl(3) calls must have the last argument casted to (char *)NULLmestre
At the time when this was commited me and tb@ discussed that it shouldn't be changed, but still snucked in within a larger diff that we didn't notice. OK tb@
2016-03-08- ranf() and franf() are prototyped on trek.h but ranf.c doesn't include it somestre
do it - Replace random() >> 5 by only random(): this was discussed a few months ago and naddy@ said at the time "Those games were originally written with the rand(3) function. The lower bits returned by rand(3) suffered from notoriously poor randomness, so this idiom developed where people would use the higher, more random bits." OK tb@ after his remarks
2016-03-08Headers cleanup with and OK tb@mestre
This was prompted by an initial patch sent by Edgar Pettijohn <edgar ! pettijohn-web.com> but the actual commit is different
2016-03-07eliminate do_malloc() and do_free().tb
These are wrappers for malloc(3) and free(3) with NULL checks. do_free() is pointless since free() already checks for NULL. do_malloc() is used only three times, once asprintf(3) seems more appropriate, and for just two calls the benefit of a custom wrapper is minimal. ok millert@
2016-03-07Remove unused fields posfile and was_pos_file from FILEDESC andtb
simplify is_fortfile() accordingly. The last use of them was guarded by OK_TO_WRITE_DISK, which was unifdef'ed in revision 1.43 last fall. tweak + ok mestre@
2016-03-07remove -u? from usage();Jason McIntyre
2016-03-07- General changes:mestre
- Remove -? from getopt(3) options, but still keep (or add) -h where applicable - Replace hardcoded program strings by getprogname(3) - Specific changes: - atc(6): this used -? and -u for usage(), remove both from game and manpage - bcd(6): use __progname instead of getprogname(3), no need to include stdlib.h - hunt(6): replace fputs(3) by fprintf(3) OK tb@ after his suggestions
2016-03-05Convert a hand-rolled strtonum to a call to strtonum(3). This preventstb
integer overflow on bogus input and bizarre error messages. Moreover, fortune files can now be named anything except names matching the regex ^[0-9][0-9.]*%$ ok mestre@
2016-03-05KNF: wrap three overly long lines. No binary change.tb
2016-03-04- Convert atoi(3) to strtonum(3)mestre
- Replace hardcoded program string by getprogname(3) - Remove '?' from getopt(3)'s switch default case (but still keep 'h') OK tb@ after his suggestions
2016-03-02Fix score file nameTim van der Molen
2016-02-28Add back undocumented -h switch defaulting to usage().tb
pjanzen@ correctly pointed out that a majority of games do this, so no need to deviate here.
2016-02-27Untangle a mess of nested ternary operators.tb
ok mestre@
2016-02-26- Remove -h and -? from getopt(3), they weren't documented on manpage anywaymestre
- Replace hardcoded string "hangman" by getprogname(3) OK tb@
2016-02-26- Convert atoi(3) to strtonum(3)mestre
- Remove lint-style comment - Remove usage() since errors are now more informative (the usage is still available in the manpage) With this diff I made it accept 0 as rotation whereas before it didn't, but alas if you use 0 then it defeats the whole purpose of the game. Initial diff sent by Peter Williams <peterbw at gmail.com>, tweaked by me and several hints and OK by tb@. I'm in desperate need of a coffee, thank you tb@ for making me notice that!
2016-02-09- Remove parameter fd from snscore() since it's never usedmestre
- And while here, fwrite(3) returns size_t whereas nscores is an int, so cast nscores to u_int. This is a false positive, but silences a compiler warning with -Wextra -pedantic tb@ : "Looks ok to me" after suggestion from him
2016-02-02- Swap atoi(3) for strtonum(3)mestre
- Swap fputs(3) for fprintf(3) - Use getprogname(3) instead of hardcoded string OK and help from tb@
2016-01-27- optarg and optind are declared by unistd.h, so remove them...Gleydson Soares
- use strtonum rather than atoi - zap case '?' in getopt(3) switch - use _exit(2) in signal handler - use __progname in usage() instead of hardcoded name OK tb@ mestre@
2016-01-25Remove unused headermestre
2016-01-19Teach morse(6) the <AC> prosign as '@', as added on May 24, 2004 (theStuart Henderson
160th anniversary of the first public Morse telegraph transmission). Support decoding (only; not encoding) of other prosigns, including <SK> as we were previously using for '@'. From pjanzen.

OK tb@
2016-01-09This diff is rather large, but it's just simply removing unnecessary headersmestre
, remove some lint-style comments, add missing void to functions without args, also some function prototypes (extern) were missing their args, so I added them as they were defined in hack.h OK tb@ on separate diffs
