|
|
Remove config/config.rpath as it is deduced automatically these days.

|
|
jm_PREREQ_QUOTEARG, jm_PREREQ_REGEX, AC_FUNC_FNMATCH_GNU, jm_AC_DOS):
|
|
Remove; not needed here, as our files don't use them directly

Detailed if-then-else, diff3 Hunks, Detailed diff3 Normal):

|
|
test intended to suppress compiler warnings.

|
|
* lib/setmode.c (__attribute__): New macro.

|
(set_binary_mode): Define only if HAVE_SETMODE_DOS.

|
Otherwise define a dummy static char, as C89 requires
|
|
that we define something.
|
|
* lib/setmode.h (set_binary_mode): Return true, not 1.
|
|
|
|
* src/analyze.c, src/context.c, src/diff.c, src/io.c, src/util.c:

Do not include regex.h, as diff.h does this now.
|
|
|
|

|

'patch' created inaccessible regular empty files to denote
|
|
nonexistent backups. Don't compare such files.
|
|
Clear st_* members of status of nonexistent file.
|
|
Remove now-unnecessary tests.
|
|
|
|
* src/diff.h: Include regex.h, unlocked-io.h.
|
|

|
|
space on hosts where bool takes more space than char.

|

|
|
Add --strip-trailing-cr support.

|
|
after failed execvp in child. Report this in parent.

|
|
|
* src/dir.c: Include <strcase.h>.
|
|
(failed_locale_specific_sorting): Renamed from failed_strcoll.
|
|
All uses changed.
|
|
(compare_names): Don't invoke strcasecmp first thing when
|
|
ignore_file_name_case; if locale_specific_sorting, we should
|
|
just use that.
|
|
|
|
* src/ifdef.c (next_line): Remove; replace with...
|
|
(next_line0, next_line1): New vars.
|
|

|
Use them to fix line-number computation bug.
|
|
|
|
* src/io.c (find_and_hash_each_line): Don't convert char *
|
|
to unsigned char *; just leave pointers as char *. This

|
|
|
|
* src/sdiff.c: Include <unlocked-io.h>, <exit.h>.

accept a new arg MAX_OK_STATUS. All callers changed.

Handle status 126/127 as per POSIX.

|
|
|
|
* src/system.h (S_IRWXU, S_IRWXG, S_IRWXO): Define if not defined.
|
|
(S_IXUSR, S_IXGRP, S_IXOTH): Remove.

Include <time.h> unconditionally, since we can assume C89 now.

|
Likewise for <stdlib.h>, <string.h>.

|
|
memcmp, memcpy): Remove decl; no longer needed.
|
|
(strcasecoll, strcasecmp): Define if not built in.
|
|
(CTYPE_DOMAIN, ISPRINT, ISSPACE, TOLOWER, _tolower, errno): Remove;
|
|
we now assume C89 or better. All uses changed.
|
|
Include <stdbool.h> unconditionally now, since gnulib supports it
|
|
if the C compiler doesn't. All boolean uses of 0 and 1 now
|
|
changed to false and true.
|
|
(lin_is_printable_as_long_int): Renamed from lin_is_printable_as_long.
|
|
|
|
* src/util.c (begin_output): Fix bug: 0 wasn't cast to char * arg,
|
|
which led to undefined behavior on 64-bit hosts.
|
|
Use more-standard test for exit status 126 versus 127.
|
|
(finish_output): Likewise.
|
|
(analyze_hunk): Do not cast bool to int.
|
|
|
|

|
|
|
|
* src/cmp.c (main): Don't consider two files with the same name to
|
|
be the same, if their initial skip values differ. This fixes a
|
|
bug reported by Hideki Iwamoto in
|
|
<http://mail.gnu.org/archive/html/bug-gnu-utils/2004-03/msg00024.html>.
|
|
|
|
2004-03-11 Paul Eggert <eggert@twinsun.com>
|
|
|
|
* src/analyze.c (diag): Return void, not lin, since the return
|
|
value wasn't needed. All callers changed.
|
|
(diag, diff_2_files):
|
|
Use 'true' and 'false' instead of '1' and '0', when appropriate.
|
|
(compareseq): Use lin const * local variables instead of lin *.
|
|
Don't bother checking diag's return value.
|
|
(shift_boundaries, build_reverse_script, build_script, diff_2_files):
|
|
Use char arrays, not bool arrays, since
|
|
sizeof (bool) might be greater than 1.
|
|
|
|
2004-02-09 Paul Eggert <eggert@twinsun.com>
|
|
|
|
* m4/setmode.m4 (AC_FUNC_SETMODE_DOS): AC_LIBOBJ(setmode) if
|
|
we would return true.

|
|
|
2002-10-14 Paul Eggert <eggert@twinsun.com>
|
|
|
|
* src/Makefile.am (diff3.$(OBJEXT), diff.$(OBJEXT),
|
|
sdiff.$(OBJEXT)): Rename from (misspelled) diff3.$(OBJECT),
|
|
diff.$(OBJECT), sdiff.$(OBJECT). Patch by Paul D. Smith in
|
|
<http://mail.gnu.org/pipermail/bug-gnu-utils/2002-October/003251.html>.
|
|
Bug reported by Chris Bainbridge.
|
|
|
|
2002-10-13 Paul Eggert <eggert@twinsun.com>
|
|
|
|
* src/Makefile.am (MOSTLYCLEANFILES): Add paths.ht.
|
|
(paths.h): Send output to paths.ht first, and then rename to
|
|
paths.h at the end. This avoids problems if the disk is full.
|
|
It also works around what appears to be a bug with GNU make -j
|
|
(3.79.1); see <http://bugs.gentoo.org/show_bug.cgi?id=8934>.
|
|
|
|

|
|
New macro. Use it uniformly instead of
|
|

|
|
command, test for a terminating null character, not for a newline.

|
|
|
|
Add internationalization support.
|
|
Several messages have been changed slightly,
|
|
to make them more consistent and easier to translate.
|
|
All strings that are messages are passed through gettext once before
|
|
being used, so that they can be localized.
|
|
Each function and macro whose first parameter is a gettext msgid
|
|
has had its first parameter's name changed so it ends in `msgid'.
|
|
All arrays of msgids have had their names changed to end in `msgid'.
|
|
`getmsgids' uses this to determine which strings are msgids.

`/* not FOO */'.
|
|

|
Tue Sep 13 18:46:43 1994 Paul Eggert <eggert@twinsun.com>
|
|
|
|
* configure.in (AC_FUNC_MEMCHR): Remove. Autoconf didn't adopt this,
|
|
since we need not worry about an old experimental library
|
|
where memchr didn't work.
|
|
(AC_FUNC_MEMCMP): Not needed, since we only test for equality.
|
|
(AC_REPLACE_FUNCS): Add test for memchr.
|
|
(AC_CHECK_FUNCS): Check for memchr, not memcpy, since it'll be cached.
|
|
(AC_CHECK_HEADERS): Add string.h; regex.c uses on some old hosts.
|
|
|
|
* system.h (memcmp): Define in terms of bcmp.
|
|
Use HAVE_MEMCHR to test for all mem* routines.
|
|
|
|
* Makefile.in (srcs): Remove memcmp.c.
|
|
We use bcmp if memcmp doesn't work, since we only test for equality.
|
|
|
|
Mon Sep 12 15:52:22 1994 Paul Eggert <eggert@twinsun.com>
|
|
|
|
* configure.in (AC_CONFIG_HEADER): Rename config.h.in to config.hin.

|
|
(distfiles): Rename config.h.in->config.hin, install.sh->install-sh.
|
|
(Makefile, config.h, config.hin, config.status): Rework for
|
|
compatibility with Autoconf 2.
|
|
* io.c (binary_file_p): Assume non-broken memchr.
|
|
* memchr.c: Assume compiler understands void *; otherwise
|
|
we don't match GCC's internal declaration of memchr.
|
|
* system.h: Use more modern autoconf approach to standard C headers.
|
|
* version.c: Include <config.h>, not "config.h".
|
|
|
|
* diff.c, diff.h (ignore_some_line_changes):
|
|
New variable; replaces `length_varies'.
|
|
(line_end_char): Replace with '\n'; it wasn't being used consistently.
|
|
|
|
* io.c (find_and_hash_each_line): Fix inconsistencies with -b -w -i and
|
|
incomplete lines. Put incomplete lines into their own bucket.
|
|
This means line_cmp no longer needs line length arguments,
|
|
and equivalence classes' line lengths no longer need to include \n.
|
|
Invoke line_cmp only if ignore_some_line_changes.
|
|
(prepare_text_end): -B no longer ignores missing newlines.
|
|
(read_files): Allocate another bucket for incomplete lines.
|
|
|
|
* util.c (line_cmp): Now takes just two arguments. No longer
|
|
optimizes for common case of exact equality; the caller does that
|
|
optimization now. The caller is changed accordingly.
|
|
Optimize for the common case of mostly equality.
|
|
Use isupper+tolower instead of islower+toupper, for consistency.
|
|
|
|
* waitpid.c (waitpid): Fix typo with internal scoping.
|
|
|
|

|
|
Change VOID_CLOSEDIR to CLOSEDIR_VOID for Autoconf 2.
|
|
* sdiff.c, util.c (memchr, waitpid): Remove; use new substitutes.
|
|
* diff3.c (read_diff): Use new waitpid substitute.

|
|
|
|
* diff3.c (scan_diff_line), util.c (print_number_range): Don't
|
|
rely on promotion to make the old-style parameter type agree
|
|
with the prototype parameter type; this doesn't work on
|
|
Apollos running bsd4.3.
|
|
|
|
Mon Jan 3 02:05:51 1994 Paul Eggert (eggert@twinsun.com)

* Version 2.6 released.
|
|
|
|
* analyze.c (too_expensive): New variable, for heuristic to
|
|
limit the worst-case cost to O(N**1.5 log N) at the price of

|
|
configuring in a separate directory when the source directory has

|
|

|
Remove the convention that last arg -1 signifies that the lines

|
|
convention no longer works, now that line numbers might be
|
|
printed out, since the line numbers may differ.

Add first FILE * argument to output to. All callers changed.
|
|
Use a faster test for the single-fwrite optimization.

Define earlier so that malloc decl can use VOID.

When comparing standard input to a file, and using a shortcut (e.g.
|
|
looking at file sizes or inode numbers), take the lseek offset into
|
|
account before deciding whether the files are identical.
|
|
Avoid mentioning `dev_t', `ino_t' for portability to nonstandard hosts.
|
|
Use l.c.m. of files' buffer sizes, not 8 * 1024.
|
|
ferror (stdout) does not imply errno has a useful value.
|
|
If 2nd file is "-", treat it first, in case stdin is closed.
|
|
|
|
(cmp): Always compute `char_number', `smaller' for speed and simplicity.
|
|
Say `cmp: EOF on input', not `/usr/gnu/bin/cmp: EOF on input',
|
|
as per Posix.2.
|
|
|
|
(block_compare_and_count): Increment line_number argument.
|
|
Remove end_char argument; it's always '\n'. All callers changed.
|
|
Do not assume sizeof(long) == 4; this isn't true on some 64-bit hosts.
|
|
(block_compare): Minimize differences with block_compare_and_count.
|
|
|
|
(block_read): Coalesce `bp += nread's.
|
|
|
|
(printc): Remove `FILE *' arg; output to stdout. All callers changed.
|
|
|
|
* configure.in: Configure HAVE_SIGACTION, RETSIGTYPE, HAVE_VPRINTF.
|
|
Configure into config.h.
|
|
|
|
* context.c (print_context_label):
|
|
Standard input's st_mtime is no longer a special case
|
|
here, since `compare_files' now sets it to the current time.
|
|
|
|
* diff.c (usage): Sort options.
|
|
(filetype): New function.
|
|
(compare_files): Set stdin's st_mtime to be the current time.
|
|
Leave its name "-" instead of changing it to "Standard Input";
|
|
to test whether a file is stdin, we must compare its name to "-" instead
|
|
of its desc to 0, since if it's closed other file descs may be 0.
|
|
When comparing standard input to a file, and using a shortcut (e.g.
|
|
looking at file sizes or inode numbers), take the lseek offset into
|
|
account before deciding whether the files are identical.
|
|
Pretend that nonexistent files have the same filetype as existing files.
|
|
Rename `errorcount' to `failed', since it's boolean.
|
|
In directory comparisons, if a file is neither a regular file nor a
|
|
directory, just print its type and the other file's type.
|
|
|
|
* diff.h (Is_space, textchar): Remove.
|
|
(struct msg, msg_chain, msg_chain_end): Move to util.c.
|
|
(VOID): Move to system.h.
|
|
(line_cmp, version_string, change_letter, print_number_range,
|
|
find_change): New decls.
|
|
|
|
* diff.texi:
|
|
whitespace -> white space. It now stands for whatever isspace yields.
|
|
Add --ignore-initial.
|
|
|
|
* diff3.c (VOID): Move to system.h.
|
|
(version_string): Now char[].
|
|
(usage): Sort options.
|
|
(process_diff): Pacify `gcc -Wall' with a useless assignment.
|
|
(read_diff): pid is of type pid_t, not int. Use waitpid if available.
|
|
(output_diff3): Simplify test for `\ No newline at end of file' message.
|
|
|
|
* dir.c (struct dirdata): Rename `files' to `names' to avoid confusion
|
|
with external struct file_data `files'.
|
|
|
|
* io.c (line_cmp): Move declaration to diff.h.
|
|
(textchar): Remove.
|
|
(find_and_hash_each_line): Use locale's definition of white space
|
|
instead of using one hardwired defn for -b and another for -w.
|
|
|
|
* normal.c (change_letter, print_number_range, find_change):
|
|
Move decls to diff.h.
|
|
(print_normal_hunk): Now static.
|
|
|
|
* sdiff.c (SEEK_SET): Move to system.h.
|
|
(version_string): Now char[], not char*.
|
|
(private_tempnam): Remove hardcoded limit on temporary file names.
|
|
(exiterr, perror_fatal, main): When exiting because of a signal,
|
|
exit with that signal's status.
|
|
(lf_refill, main, skip_white, edit, interact): Check for signal.
|
|
(ignore_SIGINT): Renamed from `ignore_signals'.
|
|
(NUM_SIGS, initial_handler): New macros.
|
|
(initial_action, signal_received, sigs_trapped): New vars.
|
|
(catchsig, trapsigs): Use sigaction if possible, since this closes the
|
|
windows of vulnerability that `signal' has. Use RETSIGTYPE not void.
|
|
When a signal comes in, just set a global variable; this is safer.
|
|
(checksigs, untrapsig): New functions.
|
|
(edit): Pacify `gcc -Wall' with a useless assignment.
|
|
Respond to each empty line with help, not to every other empty line.
|
|
(private_tempnam): Remove hardcoded limit on temporary file name length.
|
|
Don't assume sizeof (pid_t) <= sizeof (int).
|
|
|
|
* system.h: (S_IXOTH, S_IXGRP, S_IXUSR,
|
|
SEEK_SET, SEEK_CUR,
|
|
STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO):
|
|
New macros, if system doesn't define them.
|
|
(volatile): Don't define if already defined.
|
|
(PARAMS): New macro.
|
|
(VOID): Move here from diff.h.
|
|
|
|
* util.c (struct msg, msg_chain, msg_chain_end): Moved here from diff.h.
|
|
(message5): New function.
|
|
(pr_pid): New var.
|
|
(begin_output): Allocate `name' more precisely.
|
|
Put child pid into pr_pid, so that we can wait for it later.
|
|
Don't check execl's return value, since any return must be an error.
|
|
(finish_output): Detect and report output errors.
|
|
Use waitpid if available. Check pr exit status.
|
|
(line_cmp): Use locale's definition of white space
|
|
instead of using one hardwired defn for -b and another for -w.
|
|
(analyze_cmp): Avoid double negation with `! nontrivial'.
|
|
Pacify `gcc -Wall' be rewriting for-loop into do-while-loop.
|
|
(dir_file_pathname): New function.
|
|
|
|
* version.c (version_string): Now char[], not char*.

Thu Jul 22 10:46:30 1993 Paul Eggert (eggert@twinsun.com)
|
|
|
|
* Makefile.in (dist): Replace `if [ ! TEST ]; then ACTION; fi'
|
|
with `[ TEST ] || ACTION || exit' so that the containing for-loop exits
|

(briefly_report): New function.
|
|
* diff.h (ignore_some_changes): New variable.
|
|
* diff.c (compare_files): Don't use the file size shortcut if
|

ignore_some_changes is nonzero, since the file size may differ
|
|
merely due to ignored changes.
|
|
(main): Set ignore_some_changes if we might ignore some changes.
|
|
Remove unsystematic assignment of 0 to static vars.

|
|
|
|
* io.c (find_and_hash_each_line): When running out of lines,
|
|
double the number of allocated lines, instead of just doubling

|
|
|
Wed Nov 18 20:40:28 1992 Paul Eggert (eggert@twinsun.com)
|
|
|
|
* dir.c (dir_sort): Plug memory leak: space holding directory

|
(diff_dirs): Pass struct file_data to dir_sort. Finish plugging leak.

|
|
|
|
Mon Nov 9 05:13:25 1992 Paul Eggert (eggert@twinsun.com)
|
|
|
|
* diff3.c (main, usage): Add -A or --show-all.
|
|
-m now defaults to -A, not -E. Allow up to three -L options.
|
|
(output_diff3_edscript, output_diff3_merge):
|
|
Remove spurious differences between these two functions.
|
|
Output ||||||| for -A. Distinguish between conflicts and overlaps.
|

|
|
(output_diff3_edscript, output_diff3_merge): Use them.
|
|
|
|
* io.c (find_identical_ends): shift_boundaries needs an extra
|
|
identical line at the end, not at the beginning.
|
|
|
|
* sdiff.c (edit): execvp wants char **, not const char **.
|
|
|
|
Mon Oct 19 04:39:32 1992 Paul Eggert (eggert@twinsun.com)
|
|

|
|
|
|
* diff3.c (main, make_3way_diff, using_to_diff3_block): Don't
|
|
report bogus differences (for one of -mexEX3) just because the
|
|
file0-file1 diffs don't line up with the file0-file2 diffs.
|
|
(This is entirely possible since we don't use diff's -n
|
|
option.) Always compare file1 to file2, so that diff3 sees
|
|
those changes directly. Typically, file2 is now the common
|
|
file, not file0.
|
|
(output_diff3_merge): The input file is file 0, not the common file.
|
|
|
|
(FC, FO): New macros; they replace FILE1, FILE0 for two-way diffs,
|
|
to distinguish them from three-way diffs.
|
|
|
|
* diff3.c (using_to_diff3_block): Fold repeated code into loops.
|
|
|
|
* diff3.c (make_3way_diff, process_diff): Have the *_end
|
|
variable point to the next field to be changed, not to the last
|
|
object allocated; this saves an if-then-else.
|
|
|
|
* diff3.c (process_diff): Use D_NUMLINES instead of its definiens.
|
|
|
|
* diff3.c: Make fns and vars static unless they must be external.
|
|
|

|
|

|
* diff.h (ROBUST_OUTPUT_STYLE): Likewise.
|
|
(default_line_format): Remove. All refs removed.
|
|
|
|
* ifdef.c (print_ifdef_lines): Add %L. Optimize %l\n even if user
|
|
specified it, as opposed to its being the default.
|
|
|
|
Tue Sep 29 19:01:28 1992 Paul Eggert (eggert@twinsun.com)
|
|
|
|
* diff.c (longopts, main): --{old,new,unchanged,changed}--group-format

|
|
no_diff_means_no_output if --unchanged-{line,group}-format allows it.

|
* diff.h (enum line_class): New type.
|
|
(group_format, line_format): Use it to regularize option flags.
|
|
All refs changed.

|
|
* diff.h (line_format): Renamed from line_prefix. All refs changed.

Sun Sep 27 05:38:13 1992 Paul Eggert (eggert@twinsun.com)
|
|
|
|
* diff.c (main): Add -E or --line-prefix option. Add -D'=xxx'

format to to -D<%<; similarly for default -D> format.
|
|
* diff.h (common_format, line_prefix): New variables.
|
|
* ifdef.c (format_ifdef): New function.

|
Use it for -D'=xxx', -E.
|
|
|
|
* context.c (find_hunk): Glue together two non-ignorable changes that
|
|
are exactly CONTEXT * 2 lines apart. This shortens output, removes
|
|
a behavioral discontinuity at CONTEXT = 0, and is more compatible
|
|
with traditional diff.
|
|
|
|
* io.c (find_identical_ends): Slurp stdin at most once.
|
|
|
|
* util.c (print_line_line): line_flag is const char *.

|
Thu Sep 24 15:18:07 1992 Paul Eggert (eggert@twinsun.com)
|
|
|
|
* ifdef.c (print_ifdef_lines): New function, which fwrites a sequence
|
|
of lines all at once for speed.
|
|
(print_ifdef_script, print_ifdef_hunk): Use it.
|
|
|
|
Thu Sep 24 05:54:14 1992 Paul Eggert (eggert@twinsun.com)

* diff.h, util.c: Use it instead of MEMCHR_MISSING.
|
|
|
|
Sun Sep 6 07:25:49 1992 Paul Eggert (eggert@twinsun.com)
|
|
|
|
* diff.h: (struct line_def): Replace this 3-word struct with char *.
|
|
This uses less memory, particularly for large files with short lines.
|
|
(struct file_data): New member linbuf_base counts number of lines
|
|
in common prefix that are not recorded in linbuf;
|
|
this uses less memory if files are identical or differ only at end.
|
|
New member buffered_lines counts possibly differing lines.
|
|
New member valid_lines counts valid data.
|
|
New member alloc_lines - linbuf_base replaces old linbufsize.
|
|
linbuf[0] now always points at first differing line.
|
|
Remove unused members ltran, suffix_lines.
|
|
Add const where appropriate.
|
|
(Is_space): New macro, for consistent definition of `white space'.
|
|
(excluded_filename, memchr, sip, slurp): New declarations.
|
|
* ed.c (print_ed_hunk): Adjust to diff.h's struct changes.
|
|
* context.c (pr_context_hunk): Likewise.
|
|
* ifdef.c (print_ifdef_script): Likewise.
|
|
* side.c (print_sdiff_script, print_half_line): Likewise.
|
|
* util.c (analyze_hunk, line_cmp, print_1_line): Likewise.
|
|
|
|
* analyze.c (shift_boundaries): Remove unneeded variable `end' and
|
|
unnecessary comparisons of `preceding' and `other_preceding' against 0.
|
|
(diff_2_files): When comparing files byte-by-byte for equality,
|
|
don't slurp them all in at once; just compare them a buffer at a time.
|
|
This can win big if they differ early on.
|
|
Move some code to compare_files to enable this change.
|
|
Use only one buffer for stdin with `diff - -'.
|
|
(discard_confusing_lines, diff_2_files): Coalesce malloc/free calls.
|
|
(build_script): Remove obsolete OUTPUT_RCS code.
|
|
|
|
* diff.c (add_exclude, add_exclude_file, excluded_filename): New fns.
|
|
(main): Use them for the new --exclude and --exclude-from options.
|
|
(compare_files): Don't open a file unless it must be read.
|
|
Treat `diff file file' and `diff file dir' similarly.
|
|
Move some code here from diff_2_files to enable this.
|
|
Simplify file vs dir warning.
|
|
|
|
* dir.c (dir_sort): Support new --exclude* options.
|
|
|
|
* io.c (struct equivclass): Put hash code and line length here instead
|
|
of struct line_def, so that they can be shared.
|
|
(find_and_hash_each_line): Compute equivalence class as we go,
|
|
instead of doing it in a separate pass; this thrashes memory less.
|
|
Make buckets realloc-able, since we can't preallocate them.
|
|
Record one more line start than there are lines, so that we can compute
|
|
any line's length by subtracting its start from the next line's,
|
|
instead of storing the length explicitly. This saves memory.
|
|
Move prefix-handling code to find_identical_ends;
|
|
this wins with large prefixes.
|
|
Use Is_space, not is_space, for consistent treatment of white space.
|
|
(prepare_text_end): New function.
|
|
(find_identical_ends): Move slurping here, so it's only done when
|
|
needed. Work even if the buffers are the same (because of `diff - -').
|
|
Compare prefixes a word at a time for speed.
|
|
(find_equiv_class): Delete; now done by find_and_hash_each_line.
|
|
(read_files): Don't slurp unless needed.
|
|
find_equiv_class's work is now folded into find_and_hash_each_line.
|
|
Don't copy stdin buffer if `diff - -'.
|
|
Check for running out of primes.
|
|
(sip, slurp): Split first part of `slurp' into another function `sip'.
|
|
`sip' sets things up and perhaps reads the first ST_BLKSIZE buffer to
|
|
see whether the file is binary; `slurp' now just finishes the job.
|
|
This lets diff_2_files compare binary files lazily.
|
|
Allocate a one-word sentinel to allow word-at-a-time prefix comparison.
|
|
Count prefix lines only if needed, only count the first file's prefix.
|
|
Don't bother to count suffix lines; it's never needed.
|
|
Set up linbuf[0] to point at first differing line.
|
|
(binary_file_p): Change test for binary files:
|
|
if it has a null byte in its first buffer, it's binary.
|
|
(primes): Add more primes.
|
|
|
|
* util.c (line_cmp): Use bcmp for speed.
|
|
Use Is_space, not is_space, for consistent treatment of white space.
|
|
(translate_line_number): Internal line numbers now count from 0
|
|
starting after the prefix.
|
|
(memchr): New function (if memchr is missing).
|
|
|
|
* Makefile.in: Document HAVE_ST_BLKSIZE. Link with wildmat.o.
|
|
* system.h (STAT_BLOCKSIZE): New macro based on HAVE_ST_BLKSIZE.
|
|
* configure.in: Add AC_ST_BLKSIZE.
|
|
* wildmat.c: New file.
|
|

Tue Aug 11 22:18:06 1992 John Gilmore (gnu at cygnus.com)
|
|
|
|
* io.c (binary_file_p): Use heuristic to avoid declaring info
|
|
files as binary files. Allow about 1.5% non-printing
|
|
characters (in info's case, ^_).
|
|
|
|
Tue Jul 7 01:09:26 1992 David J. MacKenzie (djm@nutrimat.gnu.ai.mit.edu)
|
|

|
|
of compiled regexps.
|

|
|
the old variables, are empty.

|
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.
|
|
(slurp): Leave 1 char extra space after each buffer.
|
|
|
|
* 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.
|
|
Cross-propagate inf[i].dir_p sooner.

|
|
|
|
* diff.h: Declare index, rindex.
|
|
|
|
* diff.c (compare_files): If comparing foodir with b/f,
|
|
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.

|
|
|
|
* 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).
