* Based on what otto@ said on icb. The expensive thing in diff ismillert2003-08-131-6/+6
| | | | | | | | newcand() (this is what blows up the memory usage so badly). Instead of counting how many times we go through the loop, count how many times we called newcand(). I renamed loopcount -> numtries since it is no longer the number of loop runs. This fixes espie@'s regression. tedu@ OK

| | | | | | | | hash function was apparently optimized for 16 bit processors and generates quite some collisions. - Fix another case of excessive reallocing. ok millert@
* o correct exit code when comparing stdin and stdin (a noop)millert2003-07-311-4/+4
| | | | | | o after copying to a temp file, lseek() to the beginning so the inline cmp routine works. Fixes an exit code issue when comparing against stdin.

* We need to initialize clen to 0 each time through diffreg() formillert2003-07-271-2/+3
| | | | | when diffreg() is called multiple times (i.e. in directory mode). Fixes a hang I saw doing "diff -r" of two large directory trees.

| | | | | | | | | producing suboptimal diffs for large file containing lots of changes. Switch heuristic off with -d/--minimal (GNU compatible). Some hints from millert@. - Improve performance by reducing the number of realloc(3) calls. ok millert@ tedu@

* Historically, when comparing two directories in -e mode, BSD diffmillert2003-07-221-14/+5
| | | | | | printed a header that turned the output into an actual script that called ed(1) to make the changes. This conflicts with POSIX so the header has been removed and the standard diff header is used instead.
* Don't print lines consisting solely of a dot ('.') in -e mode sincemillert2003-07-221-9/+38
| | | | | | | | that will confuse ed(1). POSIX says "one way to fix this bug is to output two periods whenever a lone period is needed, then terminate the append command with a period, and then use the substitute command to convert the two periods into one period." This is exactly what I have done.
* Historically, the "Only in" messages produced in dir modemillert2003-07-211-10/+5
| | | | | | | | | were not printed when the output format was -e (ed) since this prevented the output from being used as an ed script. However, POSIX specifies that this message shall always be printed regardless of the output format (this is also what GNU diff does). Also do the same with the "Common subdirectory" message which POSIX lists as optional.

| | | | | | machines with a 16 bit word size. Also replace (HALFLONG - 1) with a new define, HASHMASK since it really is a mask. None of this results in any actual change in behavior.
* Deal with files that lack a final newline before EOF (you naughtymillert2003-07-161-24/+42
| | | | | | | | | | | | | | | | | emacs users!). In most cases this just means checking for EOF in addition to '\n'. However, we need to tread carefully in readhash(). There we return 0 on EOF iff it is the first char in a "line". Additionally, if the -b or -w flags were specified and the last character in one file was '\n' but the other file is missing '\n', pretend that we didn't see the newline in the one file. This is consistent with GNU diff. For the non-{b,w} case, print "\ No newline at end of file" when we see EOF before a newline in one file where the other file has one. Again, this is for consistency with GNU diff and patch(1) in -current knows how to interpret this message. OK tedu@ and otto@

* Unlink temp file as soon as it is opened and return a FILE * formillert2003-07-093-123/+67
| | | | | | | | | | | it so we don't have to worry about cleanup. This means the quit() signal handler and error/errorx can go away too. Move splice() out of diffreg() and into diff.c where it belongs since we don't want to be calling splice() for a directory diff. Add a check for mismatched paths (one file, one dir) in diffreg.c. deraadt@ OK

| | | | | | | | | | | | | | | | | | | | | o -N is implemented o -X is implemented o -x is implemented o diff.c has been rewritten and GNU long options are now supported o diffdir.c has been rewritten + no longer does fork + exec of /usr/bin/diff + can be called recursively (and will be for -r) o diff.h + don't include any .h files here any more, do it in the .c files + no Bell Labs code in this, gets a UCB copyright (the 32v sources only have a diff.c and there is nothing in common). o diffreg.c + most all remaining globals are now private to diffreg.c + files are only opened once + dynamically allocated objects are either freed or realloced + added missing UCB copyright (there were lots of UCB changes) + print correct thing when -s is specified OK deraadt@

| | | | | | | | o get rid of now-unused tempfile variable o move inifdef into diffreg.c (only used there) o correct a comment o use _PATH_DIFF, _PATH_DIFFH and _PATH_PR instead of variables set to them o get rid of hack to look for pr and diff in /bin
