2013-01-20remove obsolete BUGS (cmp is not run internally); ok ottoJason McIntyre
2012-11-29Change scandir()'s 'select' argument fromPhilip Guenthe
int (*)(struct dirent *) to int (*)(const struct dirent *) to match POSIX. ok millert@, ports check by naddy@
2012-07-08Switch diff(1) binary file detection from !(isprint() || isspace()) toStefan Sperling
checking for embedded NULs, as was done for grep(1) some time ago. Avoids problems with e.g. latin1-encoded files being treated as binary, since isprint() uses only ASCII by default and diff(1) doesn't call setlocale(). prodded by and ok bluhm
2012-05-22Strip trailing slashes from directory in splice() beforeTodd C. Miller
appending the file portion. OK krw@ matthew@

diff originally from Daniel Dickman, but otto suggested this paper ok otto millert
2010-11-14scandir() does not NULL-terminate the list of dirent structs so useTodd C. Miller
the returned count and set and end pointer instead. we no longer need to allocate a dummy array when diffing against a non-existent directory so eliminate slurpdir() and call scandir() directly. OK krw@
2010-11-08getdirentries(2) should be avoided outside of libc so use scandir(3)Todd C. Miller
instead. This makes slurpdir() just a thin wrapper around scandir(3). OK schwarze@
2010-10-28Change basep parameter of getdirentries() to be off_t *, not long *Todd C. Miller
so it works correctly with large offsets (and matches other systems). This requires adding a new getdirentries syscall, with the old one renamed to ogetdirentries. All in-tree consumers of getdirentries() have been updated. Bump libc and libpthread major numbers. OK and with deraadt@
2010-09-03add an EXIT STATUS section for /usr/bin;Jason McIntyre
2010-08-18Add a cross reference to patch(1)Ingo Schwarze
as suggested by Thomas de Grivel <billitch at gmail dot com> on tech@. While here, remove the SEE ALSO entries (but not the cross references at the appropriate places!) to fnmatch(3), re_format(7), and pr(1). Their relevance is restricted to one single option each, the latter is mostly obsolete nowadays anyway, and the number of SEE ALSO entries is so large that SEE ALSO is starting to look confusing. "yes" jmc@

OK millert
2010-07-15cvs and rcs use diff_output() to print everything since it is notRay Lai
always to stdout. A large number of differences are due to this. This diff reduces many more differences between diff and cvs/rcs. Personally I think it's kinda ugly. =( "Looks fine" millert
2010-07-15Remove unused arguments from check(). From cvs/rcs.Ray Lai
OK millert
2010-07-14Return -1 on error as advertised.Ray Lai
Handle case when only one stream failed. OK otto, millert
2010-03-22Even though this cannot happen in the diff -r case,Ingo Schwarze
even though diff(1) will exit(3) soon after this mkstemp(3) failure, even though this cannot really leak anything, close the file descriptor as soon as it is not used any more to make correctness of the code more obvious. patch from Igor Zinovik <zinovik dot igor at gmail dot com> on tech@ "looks nice" deraadt@

2009-10-28rcsid[] and sccsid[] and copyright[] are essentially unmaintained (andTheo de Raadt
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
2009-06-07More cvs/diff/rcs convergence:Ray Lai
1. Mostly variable/function renaming, SIZE_T_MAX->SIZE_MAX, and spacing. 2. One strchr -> strncspn. 3. diff had a weird thing where it set file[12] = ofile[12] but never updated file or ofile, then if file and ofile were different it freed it. I removed it. OK millert
2009-06-06Oops, forgot to pass dflags to diffreg. Now the flags work again.Ray Lai

- note which options are extensions to POSIX
2007-05-29Bring in some changes from rcsdiff:Ray Lai
1. Replace all the e*alloc functions with the x*alloc versions. 2. Whitespace syncs according to style. 3. Remove the __inline stuff. 4. Remove the min/max functions, using the MAX/MIN macros instead. OK millert@
2007-03-18improve -p for C++ code: classes definition often haveMarc Espie
public:/protected:/private: at the start of line. This lets the -p scanner just take note of the section and keep looking for the actual class definition. Also increase function name bufsize so it shows most of these pesky C++ decls... okay otto@

okay millert@
2007-02-22Defer printing of the per-file diff header until after the regexpTodd C. Miller
"ignore" processing has finished. This way we only print the header for files that have diffs. The new behavior matches GNU diff (which is where the -I flag comes from). OK otto@ espie@
