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

2015-12-22The loop index in grep_cmp() should be size_t to match the type ofTodd C. Miller
the length parameter. The return value of grep_cmp() is only used in a boolean context so make it return bool instead of the index. OK mmcc@

64 bits. ok kettenis@
2015-12-07Represent line numbers with off_t rather than int. This preventsmmcc
overflow on huge inputs. ok millert@, deraadt@

OK millert@ deraadt@
2015-10-09Change all tame callers to namechange to pledge(2).Theo de Raadt
2015-10-03grep only opens files read-only, reads via stdio or other methods, performsTheo de Raadt
computation, and outputs result to stdout. (note: in the tame model, malloc is implicit because stdio needs it, and mmap is implicit since malloc needs it; libz is satisfied by this environment also). this tame change consists of 1 line, setting "stdio rpath" before getopt. this protection is fairly strict. grep could be improved further by computing a wpathlist based on argv, keeping -R in mind. feel free to take a shot at it. grep was an early target of capsicum also. know anyone running capsicum grep? ok doug
2015-08-27use strtonum to parse the number of lines of context.David Gwynne
this provides better error messages. ok deraadt@ guenther@
2015-06-25Put fts_close() where missing.Masao Uebayashi
Not bugs in short-lived commands that call exit() -> _exit() immediately, but for idempotency. Originally found in ls(1) by Valgrind. Changes for other commands are from deraadt@. Reviewed by me, tested in snapshots. OK deraadt@
2015-04-30Add warning when user specifies -R but no files, like GNU grep.Todd C. Miller
OK schwarze@ ian@
2015-03-16Don't include limits.h or sys/limits.h since grep.h already does itTodd C. Miller
for us.
2015-03-16Include limits.h, not sys/limits.h and include stdint.h for SIZE_MAX.Todd C. Miller
2015-02-06SIZE_MAX is standard, we should be using it in preference to theTodd C. Miller
obsolete SIZE_T_MAX. OK miod@ beck@
2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers whereTheo de Raadt
possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)
2015-01-13An article on medium.com highlighted that grepDaniel Dickman

initially proposed a different fix. OK otto@

2011-07-17Fix an integer overflow for very long lines by replacing the datatype of 2 ↵aschrijver
offsets from int to regoff_t. Bail if the given size_t line length doesn't fit into the new regoff_t. "I don't think you will ever be able to get a string longer than SSIZE_MAX into memory, but that looks good." tedu@ "Agreed" otto@ regoff_t suggested by otto@

reminded this was useful by ajcoutot
2011-06-20Switch binary file detection from !(isprint() || isspace()) to checkingStefan Sperling
for embedded NULs. Matches GNU and FreeBSD grep, and avoids problems with e.g. latin1-encoded files being treated as binary in the UTF-8 locale once grep calls setlocale() (which it does not, yet). OK millert@ tedu@
