12 Check for patch file too long (i.e., its size
13 doesn't fit in a `long', and LFS isn't available).
16 Cast malloc return value, in case malloc returns char *.
18 1997-07-16 Paul Eggert <eggert@twinsun.com>
20 * configure.in (VERSION): Bump to 2.4.3.
22 * NEWS, patch.man, pch.c (intuit_diff_type, get_line, pget_line):
23 Now demangles RFC 934 encapsulation.
24 * pch.c (p_rfc934_nesting): New var.
26 * pch.c (intuit_diff_type): Don't bother to check file names carefully
27 if we're going to return NO_DIFF.
29 * inp.c (plan_a): Count the number of lines before allocating
30 pointer-to-line buffer; this reduces memory requirements
31 considerably (roughly by a factor of 5 on 32-bit hosts).
32 Decrease `size' only when read unexpectedly reports EOF.
34 (too_many_lines): New fn.
35 (re_input): Free i_buffer if using plan A.
36 Free buffers unconditionally; they can't be zero.

45 * configure.in (VERSION): Bump to 2.4.2.
47 * util.c (ok_to_reverse), NEWS: The default answer is now `n';
48 this is better for Emacs.

61 * patch.c (option_help): Put version control options together.
62 (get_some_switches): With CVS 1.9 hack, treat -b foo like -b -z foo,
63 not just -z foo. This change is needed due to recent change in -z.
64 * backupfile.c (find_backup_file_name):
65 backup_type == none causes undefined behavior;
66 this undoes the previous change to this file.
68 * patch.c (locate_hunk): Fix bug when locating context diff hunks
69 near end of file with nonzero fuzz.
71 * util.c (move_file): Don't assume that ENOENT is reported when both
72 ENOENT and EXDEV apply; this isn't true with DJGPP, and
73 Posix doesn't require it.
75 * pch.c (there_is_another_patch):
76 Suggest -p when we can't intuit a file.
78 1997-06-19 Paul Eggert <eggert@twinsun.com>

127 * pc/djgpp/config.sed:
128 Convert from .h file to .sed script that generates .h file.
130 * NEWS: Describe --backup-if-mismatch, --no-backup-if-mismatch.
132 Describe new options --backup-if-mismatch, --no-backup-if-mismatch

169 Ignore Index: line if either old or new line is present, and if
170 POSIXLY_CORRECT is not set.

200 (HAVE_RAISE): New macro.
201 (HAVE_UTIME_H): Define.

229 (ask): Remove unnecessary close of ttyfd.
230 When there is no terminal at all, output a newline to make the
231 output look nicer. After reporting EOF, flush stdout;

241 * configure.in (VERSION): Bump to 2.3.5.
243 * util.c (ok_to_reverse):
244 Be less chatty if verbosity is SILENT and we don't
245 have to ask the user. If force is nonzero, apply the patch anyway.
247 * pch.c (there_is_another_patch):
248 Before skipping rest of patch, skip to
249 the patch start, so that another_hunk can skip it properly.

281 1997-06-01 Paul Eggert <eggert@twinsun.com>
283 * configure.in (VERSION): Bump to 2.3.2.

307 * pch.c (open_patch_file):
308 Fatal error if binary_transput and stdin is a tty.

328 case-changing tricks to come up with backup file name; it's
329 not portable to case-insensitive file systems.
330 * common.h (ISLOWER): Remove.
332 * inp.c (scan_input): Don't use Plan A if (debug & 16).
334 * patch.c (shortopts): Add -g, -G.

370 Use patch_get, not backup_type, to decide whether to
371 get from RCS or SCCS. Use the word `get' in diagnostics.
372 * patch.c (main): Initialize patch_get from PATCH_GET.
373 Omit DEFAULT_VERSION_CONTROL hook; it just leads to nonstandarization.

433 Don't chmod output file if input file did not exist.
434 chmod rej file to input file's mode minus executable bits.
435 (locate_hunk): Go back to old way of a single fuzz parameter, but
436 handle it more precisely: context diffs with partial contexts

441 (ok_to_reverse): Move to util.c.
443 * inp.c (scan_input, get_input_file): Quote file names in diagnostics.

512 When creating temporaries, use file modes of original files.
513 (longopts, get_some_switches): New option --binary.

847 Be less chatty unless --verbose.
848 (get_input_file): New function, split off from plan_a.
849 Reuse file status gotten by pch if possible. Allow for dry run.

852 (plan_a): Rewrite for speed.
853 Caller now assigns result to using_plan_a.
854 Don't bother reading empty files; during dry runs they might not exist.

868 1 means hunks were rejected, 2 means trouble.

875 Add support for --dry-run, --output, --verbose.
876 Invoke get_input_file first, before deciding among do_ed_script,
878 Clear ofp after closing it, to keep discipline that ofp is either
879 0 or open, to avoid file descriptor leaks. Conversely, rejfp doesn't
880 need this trick since static analysis is enough to show when it
882 Don't allow file-creation patches to be applied to existing files.
883 Misordered hunks are now not fatal errors; just go on to the next file.
884 It's a fatal error to fall back on plan B when --output is given,
885 since the moving hand has writ.
886 Add support for binary files.
887 Check for I/O errors.
888 chmod output file ourselves, rather than letting move_file do it;
889 this saves global state.
890 Use better grammar when outputting hunks messages, e.g. avoid

893 Remove support for multiple file arguments.
894 Move get_some_switches call from reinitialize_almost_everything

911 -B now implies backup, and requires nonempty operand.
912 -D no longer requires first char of argument to be an identifier.
913 `-o -' is now disallowed (formerly output to regular file named "-").
914 -p operand is now required.
915 -v no longer needs to cleanup (no temp files can exist at that point).
916 -V now implies backup.

918 do not set filearg. It's now an error if extra operands are given.
919 (abort_junk): Check for write errors in reject file.

925 (OUTSIDE, IN_IFNDEF, IN_IFDEF, IN_ELSE): Now part of an enumerated type
926 instead of being #defined to small integers.
927 Change while-do to do-while when copying !-part for R_do_defines,
928 since condition is always true the first time through the loop.
929 (init_output, init_reject): Arg is now const *.
930 (copy_till, spew_output): Do not insert ``missing'' newlines;
931 propagate them via new after_newline argument.
932 (spew_output): Nothing to copy if last_frozen_line == input lines.
933 Do not close (ofp) if it's null.
935 (similar): Ignore presence or absence of trailing newlines.

938 (cleanup): New function.
939 (fatal_exit): Use it. Renamed from my_exit.

942 * pch.h, pch.c (pch_prefix_context, pch_suffix_context):
943 New fns replacing pch_context.
944 (another_hunk): Now yields int, not bool; -1 means out of memory.
945 Now takes difftype as argument.
946 (pch_write_line): Now returns boolean indicating whether we're after
947 a newline just after the write, for supporting non-text files.
948 * pch.c (isdigit): Remove; use ISDIGIT instead.
949 (INITHUNKMAX): Moved here from common.h.
950 (p_context): Removed. We need to keep track of the pre- and post-
951 context separately, in:

954 (open_patch_file): Arg is now char const *.
955 Copy file a buffer at a time, not a char at a time, for speed.

962 Strip paths as they're being fetched.
963 Set ok_to_create_file correctly even if patch is reversed.
964 Set up file names correctly with unidiff output.
965 Use algorithm specified by POSIX 1003.2b/D11 to deduce
966 name of file to patch, with the exception of patches
967 that can create files.
968 (skip_to): Be verbose if !inname, since we're about to ask the
969 user for a file name and the context will help the user choose.
970 (another_hunk): Keep context as LINENUM, not int.
971 If the replacement is missing, calculate its context correctly.
972 Don't assume input ends in newline.
973 Keep track of patch prefix context separately from suffix context;
974 this fixes several bugs.
975 Don't assume blank lines got chopped if the replacement is missing.
976 Report poorly-formed hunks instead of aborting.
977 Do not use strcpy on overlapping strings; it's not portable.
978 Work even if lines are incomplete.
979 Fix bugs associated with context-less context hunks,
980 particularly when patching in reverse.
981 (pget_line): Now takes just 1 arg; instead of second arg,
982 just examine using_plan_a global. Return -1 if we ran out
984 (do_ed_script): Now takes output FILE * argument.
985 Take name of editor from ED_PROGRAM instead of hardwiring /bin/ed.
986 Don't bother unlinking TMPOUTNAME.
987 Check for popen failure.
988 Flush pipe to check for output errors.
989 If ofp is nonzero, copy result to it, instead of trying to
992 * util.h, util.c (say1, say2, say3, say4, fatal1, fatal2, fatal3,

1020 (zask): Renamed from `ask'. Now uses stdarg. Output to stdout,
1021 and read from /dev/tty, or if that cannot be opened, from
1022 stderr, stdout, stdin, whichever is first a tty.
1023 Print "EOF" when an EOF is read. Do not echo input.
1025 (sigset_t, sigemptyset, sigmask, sigaddset, sigismember, SIG_BLOCK,
1026 SIG_UNBLOCK, SIG_SETMASK, sigprocmask, sigblock, sigsetmask):

1029 (fatal_exit_handler): New function, if !HAVE_SIGACTION.
1030 (set_signals, ignore_signals): Use sigaction and sigprocmask style

1033 (mkdir): First arg is now const *.
1034 (makedirs): Handle multiple adjacent slashes correctly.

1036 (that is now the caller's responsibility).
1037 Treat a sequence of one or more slashes like one slash.
1038 Do not unstrip leading directories if they all exist and if
1039 no -p option was given; POSIX doesn't allow this.
1040 (memcmp): Remove (now a macro in common.h).
1042 * version.c (copyright_string, free_software_msgid, authorship_msgid):
1044 (version): Use them. Use program_name instead of hardwiring it.

1071 configure, to get the right args passed.
1073 Thu Jul 29 07:46:16 1993 Paul Eggert (eggert@twinsun.com)
1075 * The following changes remove all remaining fixed limits on memory,
1076 and fix bugs in patch's handling of null bytes and files that do not
1077 end in newline. `Patch' now works on binary files.
1079 * backupfile.c (find_backup_file_name): Don't dump core if malloc fails.
1081 * EXTERN.h, INTERN.h (EXITING): New macro.

1085 (CANVARARG): Remove varargs hack; it wasn't portable.
1086 (filearg): Now a pointer, not an array, so that it can be reallocated.
1087 (GET*, SCCSDIFF, CHECKOUT*, RCSDIFF): Quote operands to commands.
1088 (my_exit): Declare here.
1089 (BUFFERSIZE, Ctl, filemode, Fseek, Fstat, Lseek, MAXFILEC, MAXHUNKSIZE,

1091 All invokers changed.
1092 (Argc, Argv, *define[sd], last_offset, maxfuzz, noreverse, ofp,
1093 optind_last, rejfp, rejname): No longer externally visible; all
1095 (INT_MAX, INT_MIN, STD*_FILENO, SEEK_SET): Define if the underlying
1096 system doesn't. Include <limits.h> for this.
1098 * configure.in: Add limits.h, memcmp. Delete getline.

1101 (TIBUFSIZE_MINIMUM): New macro.
1102 (report_revision): New function.
1103 (plan_a): Do not search patch as a big string, since that fails
1104 if it contains null bytes.
1105 Prepend `./' to filenames starting with `-', for RCS and SCCS.
1106 If file does not match default RCS/SCCS version, go ahead and patch
1107 it anyway; warn about the problem but do not report a fatal error.
1108 (plan_b): Do not use a fixed buffer to read lines; read byte by byte
1109 instead, so that the lines can be arbitrarily long. Do not search
1110 lines as strings, since they may contain null bytes.
1111 (plan_a, plan_b): Report I/O errors.
1113 * inp.c, inp.h (rev_in_string): Remove.
1114 (ifetch): Yield size of line too, since strlen no longer applies.
1115 (plan_a, plan_b): No longer exported.
1117 * patch.c (abort_hunk, apply_hunk, patch_match, similar):
1118 Lines may contain NUL and need not end in newline.
1119 (copy_till, dump_line): Insert newline if appending after partial line.
1120 All invokers changed.
1121 (main, get_some_switches, apply_hunk): Allocate *_define[ds], filearg,
1122 rejname dynamically.
1123 (make_temp): New function.
1125 (main, spew_output, dump_line) Check for I/O errors.
1127 * pch.c (open_patch_file): Don't copy stdin to a temporary file if
1128 it's a regular file, since we can seek on it directly.
1129 (open_patch_file, skip_to, another_hunk): The patch file may contain
1131 (another_hunk): The patch file may contain lines starting with '\',
1132 which means the preceding line lacked a trailing newline.
1133 (pgetline): Rename to pget_line.
1134 (get_line, incomplete_line, pch_write_line): New functions.
1135 (pch_line_len): Return size_t, not short; lines may be very long.
1136 (do_ed_script): Check for I/O errors. Allow scripts to contain
1137 'i' and 's' commands, too.
1139 * pch.h (pfp, grow_hunkmax, intuit_diff_type, next_intuit_at, skip_to,
1140 pfetch, pgetline): No longer exported.
1141 (pch_write_line): New declaration.

1147 (zask): Use STD*_FILENO instead of 0, 1, 2.
1148 (fetchname): strip_leading defaults to INT_MAX instead of 957 (!).
1149 (memcmp): Define if !HAVE_MEMCMP.
1151 * util.c, util.h (say*, fatal*, pfatal*, ask*): Delete; these
1152 pseudo-varargs functions weren't ANSI C. Replace by macros
1153 that invoke [fs]printf directly, and invoke new functions
1154 [az]{say,fatal,pfatal,ask} before and after.
1155 (savebuf, read_fatal, write_fatal, memory_fatal, Fseek): New functions.
1156 (fatal*): Output trailing newline after message. All invokers changed.
1158 * version.c (version): Don't exit.
1160 * Makefile.in (SRCS): Remove getline.c.

1179 * common.h (MEM): Typedef removed.
1180 inp.c, pch.c, util.c: Use size_t instead of MEM.
1181 inp.c, pch.c: Use off_t.

1190 * common.h (BUFFERSIZE): Grow it to 8k too, just in case.
1191 (buf): Turn `buf' back into an array; making it a pointer broke
1193 * patch.c (main): Likewise.
1195 Tue Jul 20 20:02:40 1993 David J. MacKenzie (djm@goldman.gnu.ai.mit.edu)

1233 numbered_existing with no existing numbered backup.
1234 (addext): Don't use ext if !HAVE_LONG_FILE_NAMES,
1235 even if it would fit. This matches patch's historical behavior.

1256 Now contains the entire patch version number.
1257 * version.c (version): Use it.
1259 Wed Jun 9 21:43:23 1993 Paul Eggert (eggert@twinsun.com)

1268 same. This check is needed on hosts that do not report file
1269 name length limits and have short limits.

1324 CHECKOUT now just checkout unlocked copies.
1326 Fri May 28 08:44:50 1993 Paul Eggert (eggert@twinsun.com)

1510 Tue Dec 3 11:27:16 1991 David J. MacKenzie (djm at wookumz.gnu.ai.mit.edu)
1512 * patchlevel.h: PATCHLEVEL 12u5.
1514 * Makefile.SH: Change clean, distclean, and realclean targets a
1515 little so they agree with the GNU coding standards.
1516 Add Makefile to addedbyconf, so distclean removes it.
1518 * Configure: Recognize Domain/OS C library in /lib/libc.
1519 From mmuegel@mot.com (Michael S. Muegel).
1521 * pch.c: Fixes from Wayne Davison:
1522 Patch now accepts no-context context diffs that are
1523 specified with an assumed one line hunk (e.g. "*** 10 ****").
1524 Fixed a bug in both context and unified diff processing that would
1525 put a zero-context hunk in the wrong place (one line too soon).
1526 Fixed a minor problem with p_max in unified diffs where it would
1527 set p_max to hunkmax unnecessarily (the only adverse effect was to
1528 not supply empty lines at eof by assuming they were truncated).

1532 * Configure: Check for signal declaration in
1533 /usr/include/sys/signal.h as well as /usr/include/signal.h.
1535 * Configure, common.h, config.h.SH: Comment out the sprintf
1536 declaration and tests to determine its return value type. It
1537 conflicts with ANSI C systems' prototypes in stdio.h and the
1538 return value of sprintf is never used anyway -- it's always cast
1541 Thu Jun 27 13:05:32 1991 David J. MacKenzie (djm at churchy.gnu.ai.mit.edu)

1559 on the command line). From Paul Eggert.
1561 * pch.c (another_hunk): Fix from Wayne Davison to recognize
1562 single-line hunks in unified diffs (with a single line number
1563 instead of a range).
1565 * inp.c (rev_in_string): Don't use `s' before defining it. From

1580 Sun Dec 2 23:20:18 1990 David J. MacKenzie (djm at albert.ai.mit.edu)
1582 * Configure: When checking for C preprocessor, look for 'abc.*xyz'
1583 instead of 'abc.xyz', so ANSI C preprocessors work.
