|
|
|
|
Thu Jul 2 16:34:38 1998 Ian Lance Taylor <ian@cygnus.com>
|
|
|
|
Simplify the callback interface:
|
|
* diffrun.h: Don't include <stdarg.h> or <varargs.h>.
|
|
(struct diff_callbacks): Remove printf_output field.
|
|
* util.c: Include <stdarg.h> or <varargs.h>.
|
|
(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 <ian@cygnus.com>
|
|
|
|
* 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.
|
|

|
|
callbacks.

|
|
* ifdef.c: Likewise.
|
|
* normal.c: Likewise.
|
|

|
|
|
|
Fri Jan 16 14:58:19 1998 Larry Jones <larry.jones@sdrc.com>
|
|
|
|
* diff.c, diff3.c: Plug memory leaks.
|
|
|
|
Thu Jan 15 13:36:46 1998 Jim Kingdon <kingdon@harvey.cyclic.com>
|
|
|
|
* 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 <kingdon@harvey.cyclic.com>
|
|
|
|
* 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
|
|
|
|

|
|
|
|
Thu Nov 6 12:42:12 1997 Karl Fogel <kfogel@floss.red-bean.com>
|
|
and Paul Eggert <eggert@twinsun.com>
|
|
|
|
* 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 <michael@thi.nl>
|
|
|
|
* 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 <twp@twp.tezcat.com>
|
|
|
|
* 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 <signal.h>.
|
|
(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 <kingdon@harvey.cyclic.com>
|
|
|
|
* 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 <kingdon@harvey.cyclic.com>
|
|
|
|
* 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 <kingdon@harvey.cyclic.com>
|
|
|
|
* Makefile.in (util.o): Change util.c to $<, needed for srcdir.
|
|
|
|
Sat Sep 20 12:06:41 1997 Tim Pierce <twp@twp.tezcat.com>
|
|
|
|
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 <twp@twp.tezcat.com>
|
|
|
|
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.
