Baushke * diff.c: Add support for systems that do not #include * diff3.c: Ditto. 2004-10-07 Conrad T. Pino * libdiff.dep: Regenerate for "../lib/libcvs.dsp" changes made 2004-10-07. 2004-10-05 Conrad T. Pino * libdiff.dep: Regenerated for "../cvsnt.dsp" and "../lib/libcvs.dsp" changes made 2004-10-05. * libdiff.mak: Regenerated for "../cvsnt.dsp" and "../lib/libcvs.dsp" changes made 2004-10-05. 2004-09-09 Conrad T. Pino * libdiff.dep: Regenerated for "../cvsnt.dsp" changes made 2004-09-08. * libdiff.mak: Regenerated for "../cvsnt.dsp" changes made 2004-09-08. 2004-07-13 Derek Price * .cvsignore: Ignore GCC profiling data. 2004-05-15 Derek Price * libdiff.dsp: Header file list updated for GNULIB updates. * libdiff.dep: Regenerated for "libdiff.dsp" changes. * libdiff.mak: Regenerated for "libdiff.dsp" changes. (Patch from Conrad T. Pino .) 2004-04-23 Derek Price * libdiff.mak: Regenerated. 2004-04-19 Derek Price * libdiff.mak: Regenerated for "zlib/libz.dsp" change. (Patch from Conrad T. Pino .) 2004-04-17 Derek Price * libdiff.dep, libdiff.mak: Regenerated for "../cvsnt.dsw" changes. (Patch from Conrad T. Pino .) 2004-04-15 Derek Price * libdiff.dsp: Set PROP BASE directories to projet standard which has "Reset" function use project defaults. (Patch from Conrad T. Pino .) 2004-04-15 Derek Price * libdiff.dsp: Set default configuration on generated make files to Win32 Debug. (Patch from Conrad T. Pino .) * libdiff.mak: Regenerated. 2004-04-15 Derek Price * Makefile.am (EXTRA_DIST): Add libdiff.dep. * Makefile.in: Regenerated. 2004-04-15 Derek Price * libdiff.dep: New generated file. * libdiff.mak: Regenerated. (Original patch from Conrad T. Pino .) 2004-04-14 Derek Price * Makefile.am (EXTRA_DIST): Remove libdiff.dep. * Makefile.in: Regenerated. 2004-03-29 Derek Price * libdiff.mak: Regenerated with VC++ 5.0. (Original sent by Dennis Jones .) * libdiff.dep: Removed. 2004-03-28 Derek Price * libdiff.mak: ...and correct a typo in the path. 2004-03-28 Derek Price * libdiff.mak: Remove absolute path again. 2004-03-28 Derek Price * libdiff.dsp, libdiff.mak: Repair & regenerate, relativizing path that MSVC seems intent on keeping absolute. 2004-03-27 Derek Price * libdiff.dep, libdiff.mak, libdiff.dsp: Repaired & regnerated. 2004-03-26 Derek Price * .cvsignore: Ignore MSVC build cruft. * libdiff.dep, libdiff.mak, libdiff.dsp: Repaired & regnerated. 2004-03-25 Derek Price * Makefile.in: Regenerated. 2004-03-25 Derek Price * libdiff.dep, libdiff.mak: New files created by Visual C++ 6.0. * libdiff.dsp: Updated by Visual C++ 6.0. * Makefile.am (EXTRA_DIST): Add diff.dep & diff.mak. * .cvsignore: Add and remove files for new MSVC++ setup. 2004-03-20 Derek Price * diff.c (diff_run): Update string arg to const. * diffrun.h: Update prototype to match. 2003-11-25 Mark D.

(Patch from Andrew Moise .) 2003-06-13 Derek Price * diff3.c (read_diff): Fix memory leak. (Patch from Kenneth Lorber .) 2003-06-11 Derek Price * Makefile.in: Regenerate for new configure.in. 2003-06-03 Derek Price * README: Add this file to point would-be patchers to please send their changes to the GNU diffutils project and then ask us to reimport the new diffutils release with the bug fix. 2003-05-21 Derek Price * Makefile.in: Regenerate with Automake version 1.7.5. 2003-05-20 Derek Price * Makefile.in: Regenerated. 2003-05-09 Derek Price * system.h: Define S_ISSOCK on SCO OpenServer. 2003-05-09 Derek Price * Makefile.in: Regenerated. 2003-04-30 Derek Price * Makefile.in: Regenerated. 2003-04-10 Larry Jones * Makefile.in: Regenerated. 2003-03-19 Mark D. Baushke * Makefile.in: Regenerated. 2003-03-19 Derek Price * Makefile.in: Regenerated. 2003-02-25 Derek Price * Makefile.in: Regenerated. 2003-02-01 Larry Jones * util.c (finish_output): Handle EINTR from waitpid. 2002-09-24 Derek Price * Makefile.in: Regenerated using Automake 1.6.3. 2002-09-24 Larry Jones * system.h: Use HAVE_STRUCT_STAT_ST_BLKSIZE instead of the obsolete HAVE_ST_BLKSIZE. 2002-09-24 Derek Price * Makefile.in: Regenerated. 2002-04-30 Derek Price * Makefile.in: Regenerated with automake 1.6. 2002-04-28 Derek Price * diff.c: Use the system fnmatch.h when present. 2001-09-04 Derek Price * Makefile.in: Regenerated with automake 1.5. 2001-08-09 Derek Price * system.h: Source some header files when present to eliminate warning messages under Windows. (Patch from "Manfred Klug" .) 2001-08-07 Derek Price * build_diff.com: Turn on verify to get a better trace of the DCL. * diff3.c: Eliminate compiler warning. The VMS read rval is ssize_t (signed). The VMS size_t appears to be unsigned. * io.c: Eliminate compiler warning (ssize_t). (Patch from Mike Marciniszyn .) 2001-08-06 Derek Price * Makefile.in: Regenerated. 2001-07-04 Derek Price * Makefile.in: Regenerated with new Automake release candidate 1.4h. 2001-06-28 Derek Price * Makefile.in: Regenerated with new version of Automake. 2001-05-07 Larry Jones * diff3.c (diff3_run): Put the name of the output file in the error message instead of "could not open output file" to aid in debugging. 2001-04-25 Derek Price * Makefile.in: Regenerated using AM 1.4e as of today at 18:10 -0400. 2001-03-24 Noel Cragg * diff.c: fix typo in usage string. 2001-03-20 Derek Price for Karl Tomlinson * diff3.c (main): changed the common file of the two diffs to OLDFILE for merges and edscripts so that the diffs are more likely to contain the intended changes. Not changing the horizon-lines arg for the second diff. If the two diffs have the same parameters equal changes in each diff are more likely to appear the same. * analyze.c (shift_boundaries): undid Paul Eggert's patch to fix the diff3 merge bug described in ccvs/doc/DIFFUTILS-2.7-BUG. The patch is no longer necessary now that diff3 does its differences differently. I think the hunk merges provide a better indication of the area modified by the user now that the diffs are actually done between the appropriate revisions. 2001-03-15 Derek Price * Makefile.am (INCLUDES): Add -I$(top_srcdir)/lib for platforms which need the regex library there. * Makefile.in: Regenerated. 2001-03-14 Derek Price * .cvsignore: Added '.deps'. Pavel Roskin * Makefile.am: New file. * Makefile.in: Regenerated. 2001-02-22 Derek Price Pavel Roskin * Makefile.in: Don't define PR_PROGRAM - it's defined by configure. Remove separate rule for util.c. 2001-02-06 Derek Price Rex Jolliff Shawn Smith * dir.c: Replace opendir, closedir, & readdir calls with CVS_OPENDIR, CVS_CLOSEDIR, & CVS_READDIR in support of changes to handle VMS DEC C 5.7 {open,read,close}dir problems. Check today's entry in the vms subdir for more. * system.h: definitions of CVS_*DIR provided here. 2000-12-21 Derek Price * Makefile.in: Some changes to support Automake targets 2000-10-26 Larry Jones * Makefile.in: Get PR_PROGRAM from autoconf instead of hard coding. (Patch submitted by Urs Thuermann .) Also add a dependency for util.o on Makefile since PR_PROGRAM gets compiled in. 2000-08-03 Larry Jones * diff3.c (read_diff): Use cvs_temp_name () instead of tmpnam () so there's at least a chance of getting the file in the correct tmp dir. 2000-07-10 Larry Jones * util.c (printf_output): Fix type clashes. 2000-06-15 Larry Jones * diff3.c (diff3_run, make_3way_diff): Plug memory leaks. 1999-12-29 Jim Kingdon * diff.c (compare_files): Use explicit braces with if-if-else, per GNU coding standards and gcc -Wall. 1999-11-23 Larry Jones * diff3.c: Explicitly initialize zero_diff3 to placate neurotic compilers that gripe about implicitly initialized const variables. Reported by Eric Veum . 1999-09-15 Larry Jones * diff.c (diff_run): Move the setjmp call before the options processing since option errors can call fatal which in turn calls longjmp. 1999-05-06 Jim Kingdon * Makefile.in (DISTFILES): Remove libdiff.mak. * libdiff.mak: Removed; we are back to a single makefile for Visual C++ version 4. 1999-04-29 Jim Kingdon * diff.c (diff_run): Use separate statement for setjmp call and if statement. This is better style in general (IMHO) but in the case of setjmp the UNICOS compiler apparently cares (I don't have the standard handy, but there are lots of legitimate restrictions on how you can call setjmp). 1999-04-26 Jim Kingdon * Makefile.in (DISTFILES): Add libdiff.dsp libdiff.mak .cvsignore. 1999-04-26 (submitted 1999-03-24) John O'Connor * libdiff.dsp: new file. MSVC project file used to build the library. * libdiff.mak: new file. Makefile for building from the command-line. * .cvsignore: Removed un-used entries related to MSVC. Added entries to ignore directories generated by the NT build, Debug and Release. 1999-03-24 Larry Jones and Olaf Brandes * diff3.c (diff3_run): Use a separate stream for the input to output_diff3_merge instead of reopening stdin to avoid problems with leaving it open. 1999-02-17 Jim Kingdon and Hallvard B Furuseth. * util.c: Use __STDC__ consistently with ./system.h. * system.h: Add comment about PARAMS. 1999-01-12 Jim Kingdon * Makefile.in, analyze.c, cmpbuf.c, cmpbuf.h, context.c, diff.c, diff.h, diff3.c, diffrun.h, dir.c, ed.c, io.c, normal.c, system.h, util.c: Remove paragraph containing the old snail mail address of the Free Software Foundation. 1998-09-21 Jim Kingdon * util.c (printf_output): Make msg static; avoids auto initializer, which is not portable to SunOS4 /bin/cc. Reported by Mike Sutton@SAIC. 1998-09-14 Jim Kingdon * Makefile.in (DISTFILES): Add diagmeet.note. 1998-08-15 Jim Kingdon * diffrun.h (struct diff_callbacks): Change calling convention of write_output so that a zero length means to output zero bytes. The cvs_output convention is just too ugly/error-prone. * util.c (printf_output): Rewrite to parse format string overselves rather than calling vasprintf, which cannot be implemented in portable C. 1998-08-06 David Masterson of kla-tencor.com * util.c (flush_output): Don't prototype. Thu Jul 2 16:34:38 1998 Ian Lance Taylor Simplify the callback interface: * diffrun.h: Don't include or . (struct diff_callbacks): Remove printf_output field. * util.c: Include or . (printf_output): Use vasprintf and write_output callback rather than printf_output callback. * diff3.c (read_diff): Don't set my_callbacks.printf_output. Thu Jun 18 12:43:53 1998 Ian Lance Taylor * diffrun.h: New file. * diff.h: Include diffrun.h. (callbacks): New EXTERN variable. (write_output, printf_output, flush_output): Declare. * diff.c (diff_run): Add parameter callbacks_arg. Use callback functions rather than writing to stdout. Don't open a file if there is a write_output callback. Call perror_with_name rather than perror. (usage): Use callbacks if defined rather than writing to stdout. (compare_files): Call flush_output rather than fflush (outfile). * diff3.c: Include diffrun.h. Change several functions to use output functions from util.c rather than direct printing. Use diff_error and friends rather than printing to stderr. Set global variable outfile. (outfile, callbacks): Declare. (write_output, printf_output, flush_output): Declare. (diff3_run): Add parameter callbacks_arg. Use callback functions rather than writing to stdout. (usage): Use callbacks if defined rather than writing to stdout. (read_diff): Preserve callbacks and outfile around call to diff_run. * util.c (perror_with_name): Use error callback if defined. (pfatal_with_name, diff_error): Likewise. (message5): Use printf_output and write_output. (print_message_queue, print_1_line, output_1_line): Likewise. (begin_output): Reject paginate_flag if there are output callbacks. (write_output, printf_output, flush_output): New functions. * context.c: Change all output to outfile to use printf_output and write_output. * ed.c: Likewise. * ifdef.c: Likewise. * normal.c: Likewise. * side.c: Likewise. * Makefile.in (SOURCES): Add diffrun.h. ($(OBJECTS)): Depend upon diffrun.h. Fri Jan 16 14:58:19 1998 Larry Jones * diff.c, diff3.c: Plug memory leaks. Thu Jan 15 13:36:46 1998 Jim Kingdon * Makefile.in (installdirs): New rule, for when ../Makefile recurses into this directory (bug reported by W. L. Estes). Tue Nov 11 10:48:19 1997 Jim Kingdon * diff.c (diff_run): Change #ifdef on HAVE_SETMODE to #if to match the other uses (fixes compilation error on unix). * diff.c (diff_run): Don't set stdout to binary mode. Mon, 10 Nov 1997 Jim Kingdon * diff.c (run_diff): Open outfile in binary mode if --binary. Thu Nov 6 12:42:12 1997 Karl Fogel and Paul Eggert * analyze.c: applied Paul Eggert's patch to fix the diff3 merge bug described in ccvs/doc/DIFFUTILS-2.7-BUG: (shift_boundaries): new var `inhibit_hunk_merge'; use it to control something important that I don't quite understand, but Paul apparently does, so that's okay. Sat Nov 1 14:17:57 1997 Michael L.H. Brouwer * Makefile.in: Add call to ranlib to build a table of contents for the library since some systems seem to require this. 1997-10-28 Jim Kingdon * .cvsignore: Add files du jour for Visual C++, vc50.pdb and vc50.idb. * system.h: Define HAVE_TIME_H. * dir.c [_WIN32]: Define CLOSEDIR_VOID. 1997-10-18 Jim Kingdon * build_diff.com: Add diff3.c Fri Sep 26 14:24:42 1997 Tim Pierce * diff.c (diff_run): Save old value of optind before calling getopt_long, then restore before returning. Eventually it would be nice if diff_run were fully reentrant. New diff3 library for CVS. * Makefile.in (SOURCES): Add diff3.c. (OBJECTS): Add diff3.o. * diff3.c: New file, copied from diffutils-2.7. See diffutils for earlier ChangeLogs. Undefine initialize_main macro. Remove . (diff3_run): Renamed from main(). Add `outfile' argument. Remove SIGCLD handling; we do not fork. Save optind and reset to 0 before calling getopt_long; restore after option processing done. (read_diff): Use diff_run with a temporary output file, instead of forking a diff subprocess and reading from a pipe. Change DIFF_PROGRAM to "diff"; this argument is now used only for diagnostic reporting. (xmalloc, xrealloc): Removed. (diff_program): Removed. (diff_program_name): Made extern, so it may be used in other library calls like `error'. (initialize_main): New function. Namespace munging. util.c defines both fatal() and perror_with_exit(), but these cannot be used to abort diff3: both attempt to longjmp() to a buffer set in diff.c, used only by diff_run. This is an awful solution, but necessary until the code can be cleaned up. (These functions do not *have* to be renamed, since both are declared static to diff3.c and should not clash with libdiff.a, but it reduces potential confusion.) * diff3.c (diff3_fatal): Renamed from fatal. (diff3_perror_with_exit): Renamed from perror_with_exit. Eliminate exit calls. (try_help): Change from `void' to `int'. Return, do not exit. (diff3_fatal, diff3_perror_with_exit, process_diff): Change `exit' to DIFF3_ABORT. (diff3_run): Initialize jump buffer for nonlocal exits. Change exit calls to returns. Change `perror_with_exit' to `perror_with_name' and add a return. Change `fatal' to `diff_error' and add a return. The reasoning is that we shouldn't rely on setjmp/longjmp any more than necessary. Redirect stdout. (check_output): Renamed from check_stdout. Take stream argument instead of blindly checking stdout. Do not close stream, but merely fflush it. (diff3_run): Initialize outstream, and close when done. Pass this stream (instead of stdout) to output_diff3_edscript, output_diff3_merge, and output_diff3. Thu Sep 25 14:34:22 1997 Jim Kingdon * util.c (begin_output, finish_output): If PR_PROGRAM is not defined (VMS), just give a fatal error if --paginate specified. * Makefile.in (DISTFILES): Add ChangeLog build_diff.com Makefile.in. * build_diff.com: New file. Wed Sep 24 10:27:00 1997 Jim Kingdon * Makefile.in: Also set top_srcdir. Needed to make today's other Makefile.in change work. * .cvsignore: New file. * Makefile.in (COMPILE): Add -I options for srcdir (perhaps unneeded) and change -I option for lib to use top_srcdir (needed to avoid mixups with CVS's regex.h vs. the system one). Sun Sep 21 19:44:42 1997 Jim Kingdon * Makefile.in (util.o): Change util.c to $<, needed for srcdir. Sat Sep 20 12:06:41 1997 Tim Pierce New diff library for CVS, based on diffutils-2.7. See diffutils for earlier ChangeLogs. * Makefile.in, analyze.c, cmpbuf.c, cmpbuf.h, config.hin, context.c, diagmeet.note, diff.c, diff.h, dir.c, ed.c, ifdef.c, io.c, normal.c, side.c, stamp-h.in, system.h, util.c, version.c: New files. (COMPILE): Add -I../lib, so we can get getopt.h. * Makefile.in: Removed anything not related to libdiff.a. (dist-dir): New target, copied from ../lib/Makefile.in. (DISTFILES): New variable. (SOURCES): Renamed from `srcs'. (OBJECTS): Renamed from `libdiff_o'. (Makefile): Changed dependencies to reflect new, shallow config directory structure. (stamp-h.in, config.h.in, config.h, stamp-h): Removed. * stamp-h.in, config.h.in: Removed. * system.h: Remove dup2 macro (provided by ../lib/dup2.c). Include stdlib.h if STDC_HEADERS is defined (not just HAVE_STDLIB_H). Sat Sep 20 05:32:18 1997 Tim Pierce Diff librarification. * diff.c (diff_run): New function, renamed from `main'. Initialize `outfile' based on the value of the new `out' filename argument. (initialize_main): New function. * system.h: Removed initialize_main macro. * diffmain.c: New file. * Makefile.in (diff): Added diffmain.o. (libdiff): New target. (AR, libdiff_o): New variables. libdiff_o does not include xmalloc.o, fnmatch.o, getopt.o, getopt1.o, regex.o or error.o, because these functions are already present in CVS. It will take some work to make this more general-purpose. Redirect standard output. * util.c: Redirect stdout to outfile: change all naked `printf' and `putchar' statements to `fprintf (outfile)' and `putc (..., outfile)' throughout. This should permit redirecting diff output by changing `outfile' just once in `diff_run'. (output_in_progress): New variable. (begin_output, finish_output): Use `output_in_progress', rather than `outfile', as a semaphore to avoid reentrancy problems. (finish_output): Close `outfile' only if paginate_flag is set. * diff.c (check_output): New function, was check_stdout. Take a `file' argument, and flush it instead of closing it. (diff_run): Change check_stdout to check_output. (compare_files): Fflush outfile, not stdout. Eliminate exit statements. * diff.h: Include setjmp.h. (diff_abort_buf): New variable. (DIFF_ABORT): New macro. * diff.c (diff_run): Change all `exit' statements to `return'. Set up diff_abort_buf, so we can abort diff without terminating (for libdiff.a). (try_help): Return int instead of void; do not exit. * util.c (fatal): Use DIFF_ABORT instead of exit. (pfatal_with_name): Use DIFF_ABORT instead of exit. Namespace cleanup (rudimentary). Strictly speaking, this is not necessary to make diff into a library. However, namespace clashes between diff and CVS must be resolved immediately, since CVS is the first application targeted for use with difflib. * analyze.c, diff.c, diff.h, util.c (diff_error): Renamed from `error'. * version.c, diff.c, diff.h, cmp.c, diff3.c, sdiff.c (diff_version_string): Renamed from version_string. * diff.c, util.c, diff.h, diff3.c, error.c (diff_program_name): Renamed from program_name. * util.c (xmalloc, xrealloc): Removed. * Makefile.in (diff_o): Added error.o and xmalloc.o.
