print_unidiff_number_range): Don't print N,M when N=M, print
|
||
just N instead.
|
||
|
||
* README: Updated for version 1.15.
|
||
Makefile: Updated for version 1.15.

is a directory.

|
||
standard input to a directory; print error instead.

|
||
way on broken systems we can still get errors.

||
|
||
* analyze.c: To make RCS work correctly on files that don't
|
||
necessarily end in newline, introduce some changes that cause

diffs to be sensitive to missing final newline. Because

||
are conditional on `output_style == OUTPUT_RCS'.

(diff_2_files) [OUTPUT_RCS]: Suppress the "File X missing
|
||
newline" message.
|

different if exactly one of the files is missing its final
|
||
newline.
|
||
|
||
* io.c (find_and_hash_each_line): Bug fix in
|
||
ignore_space_change mode. Change line's length to include the
|
||
newline. For OUTPUT_RCS, decrement last line's length if
|

||
(find_identical_ends) [OUTPUT_RCS]: If one of the files is
|
||
missing a final newline, make sure it's not included in either
|
||
the prefix or suffix.
|
||
|
||
* util.c (print_1_line): Change line output routine to account
|
||
for line length including the newline.

Sometimes call diff_dirs if subdir exists in just one place.

and 2 through mapping off of the last difference instead of the

|
||
|
||
* io.c (slurp): Leave 2 chars space at end of buffer, not one.
|
||
(find_identical_ends): Special case if either file is empty;
|
||
don't try to make a sentinel since could crash.

|
||
add room for sentinel when calling xmalloc or xrealloc.

|
||
|
||
Fri Feb 10 01:28:15 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu)
|
||
|
||
* diff.c (main): -C now takes arg to specify context length.
|
||
Now -p to show C function name--Damned IEEE!
|
||
Fatal error if context length spec'd twice.
|
||
|
||
* ed.c (print_ed_hunk): Now special treatment only for lines containing
|
||
precisely a dot and nothing else. Output `..', end the insert,

||
|
||
* io.c (find_and_hash_lines): When backing up over starting context,
|
||
don't move past buffer-beg.
|
||
|
||
* io.c (find_identical_ends): Use sentinels to make the loops faster.
|
||
If files are identical, skip the 2nd loop and return quickly.

||
* analyze.c (diff_2_files): Mention difference in final newlines.

|
||
|
||
* dir.c (dir_sort): Open-trouble not fatal; just say # files is -1.
|
||
(diff_dirs): If dir_sort does that, give up and return 2.
|
||
|
||
* diff.c (compare_files): Don't open directories.
|
||
Don't close them specially either.
|

use foodir/f, not foodir/b/f.
|
||
|
||
* diff.c (compare_files): Don't print "are identical" msg for 2 dirs.
|
||
Status now 1 if one file is a dir and the other isn't, etc.

Thu Nov 3 16:30:24 1988 Randall Smith (randy at gluteus.ai.mit.edu)
|
||
|
||
* Makefile: Added a define for diff3 to define DIFF_PROGRAM.
|
||
|
||
* util.c: Added hack to make sure that perror was not called with
|
||
a null pointer.
|
||
|
||
* diff.c: Changed S_IFDIR to S_IFMT in masking type of file bits
|
||
out.
|
||
|
||
* diff3.c: Included USG compatibility defines.
|
||
|
||
* diff.h: Moved sys/file.h into #else USG section (not needed or
|
||
wanted on System V).
|
||
|
||
* ed.c, analyze.c, context.c: Shortened names to 12 characters for
|
||
the sake of System V (too simple not to do).
