制作2.6内核的CLFS时 patch包

	* configure.in (VERSION): Bump to 2.3.8.

	* pch.c (open_patch_file): Test stdin for fseekability.
	(intuit_diff_type): Missing context diff headers are now warnings,
	not errors; some people use patches with them (e.g. when retrying
	rejects).

	* patch.c (struct outstate):
	New type, collecting together some output state vars.
	(apply_hunk, copy_till, spew_output, init_output): Use it.
	Keep track of whether some output has been generated.
	(backup_if_mismatch): New var.
	(ofp): Remove, in favor of local struct outstate vars.
	(main): Use struct outstate.  Initialize backup_if_mismatch to
	be the inverse of posixly_correct.  Keep track of whether mismatches
	occur, and use this to implement backup_if_mismatch.
	Report files that are not empty after patching, but should be.
	(longopts, option_help, get_some_switches): New options
	--backup-if-mismatch, --no-backup-if-mismatch.
	(get_some_switches): -B, -Y, -z no longer set backup_type.
	* backupfile.c (find_backup_file_name):
	Treat backup_type == none like simple.

	* Makefile.in (CONFIG_HDRS):
	Remove var; no longer needed by djgpp port.
	(DISTFILES_PC_DJGPP): Rename pc/djgpp/config.sed to
	pc/djgpp/configure.sed; remove pc/djgpp/config.h in favor of
	new file that edits it, called pc/djgpp/config.sed.
	* pc/djgpp/configure.bat: Rename config.sed to configure.sed.
	* pc/djgpp/configure.sed (CONFIG_HDRS): Remove.
	(config.h): Add rule to build this from config.hin and
	pc/djgpp/config.sed.
	* pc/djgpp/config.sed:
	Convert from .h file to .sed script that generates .h file.

	* NEWS: Describe --backup-if-mismatch, --no-backup-if-mismatch.
	* patch.man:
	Describe new options --backup-if-mismatch, --no-backup-if-mismatch
	and their ramifications.  Use unreadable backup to represent
	nonexistent file.

	(SCCSPREFIX, GET, GET_LOCKED, SCCSDIFF1, SCCSDIFF2, SCCSDIFF3,
	RCSSUFFIX, CHECKOUT, CHECKOUT_LOCKED, RCSDIFF1, RCSDIFF2):
	Move to util.c.

	the file name.
	Say "Skipping patch." when deciding to skip patch.
	(intuit_diff_type): Look for version-controlled but nonexistent files
	when intuiting file names; set invc accordingly.
	Ignore Index: line if either old or new line is present, and if
	POSIXLY_CORRECT is not set.
	(do_ed_script): Flush stdout before invoking popen, since it may
	send output to stdout.

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

	to have TZ be unset in DOS.

1997-06-08  Paul Eggert  <[e-mail]>

	* configure.in (VERSION): Bump to 2.3.6.

 	option for -G, retired -G, and more verbose default behavior
 	with fuzz.

	* pch.c (intuit_diff_type): Record times reported for files in headers.

	!timestamp[x].
	* util.h (fetchname): Change argument head_says_nonexistent to
 	timestamp.
	* util.c: #include <partime.h> for TM_LOCAL_ZONE.

	store header timestamp into *pstamp.
	If -T or -Z option is given, match time stamps more precisely.
	(ask): Remove unnecessary close of ttyfd.
	When there is no terminal at all, output a newline to make the
	output look nicer.  After reporting EOF, flush stdout;
	when an input error, report the error type.

	* inp.c (get_input_file):
	Ask user whether to get file if patch_get is negative.

	* Makefile.in (clean): Don't clean */*.o; clean core* and *core.

	* configure.in (VERSION): Bump to 2.3.5.

	* util.c (ok_to_reverse):

	Before skipping rest of patch, skip to
	the patch start, so that another_hunk can skip it properly.
	(intuit_diff_type): Slight wording change for missing headers, to
	regularize with other diagnostics.  Fix off-by-one error when setting
	p_input_line when scanning the first hunk to check for deleted files.

1997-06-03  Paul Eggert  <[e-mail]>

	(fetchname): No need to test for null first argument.

1997-06-02  Paul Eggert  <[e-mail]>

	* configure.in (VERSION): Bump to 2.3.3.
	* pch.c (p_says_nonexistent, pch_says_nonexistent): Is now 1 for empty,
	2 for nonexistent.
	(intuit_diff_type): Set p_says_nonexistent according to new meaning.
	Treat empty files like nonexistent files when reversing.
	(skip_to): Output better diagnostic when we can't intuit a file name.
	* patch.c (main):
	Count bytes, not lines, when testing whether a file is empty,
	since it may contain only non-newline chars.
	pch_says_nonexistent now returns 2 for nonexistent files.

1997-06-01  Paul Eggert  <[e-mail]>

	* configure.in (VERSION): Bump to 2.3.2.

1997-05-26  Paul Eggert  <[e-mail]>

	* configure.in (VERSION): Bump to 2.2.93.

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

	* pc/djgpp/config.sed (chdirsaf.c):
	Use sed instead of cp, since cp might not be installed.
	* pc/djgpp/configure.bat:
	Prepend %srcdir% to pathname of config.sed, for crosscompiles.

1997-05-25  Paul Eggert  <[e-mail]>

	* configure.in (VERSION): Bump to 2.2.92.

	Do not use xxx.h -> xxxh~ hack.

	* util.c: (move_file): Avoid makedirs test when possible even
 	if FILESYSTEM_PREFIX_LEN (p) is nonzero.  Don't play
 	case-changing tricks to come up with backup file name; it's

	* patch.c (shortopts): Add -g, -G.
	(longopts): --help now maps to 132, not 'h', to avoid confusion.
	(get_some_switches): Likewise.

	Add advice for ordering of patches of derived files.
	Add /dev/tty to list of files used.
	* README: Adjust instructions for building on DOS.
	* pc/djgpp/README: Remove tentative wording.
	* NEWS: The DOS port is now tested.
	Backup file names are no longer computed by switching case.

	* pc/chdirsaf.c (ERANGE): Include <errno.h> to define it.
	(restore_wd): chdir unconditionally.
	(chdir_safer): Invoke atexit successfully at most once.
	* pc/djgpp/config.sed: Use chdirsaf.o, not pc/chdirsaf.o.
	Replace CONFIG_HDRS, don't append.
	Use $(srcdir) in CONFIG_STATUS.
	Don't apply $(SHELL) to $(CONFIG_STATUS).
	Append rules for chdirsaf.o, chdirsaf.c; clean chdirsaf.c at the end.
	* pc/djgpp/configure.bat: Append CR to each line; DOS needs this.
	Don't use | as sed s delimiter; DOS can't handle it.

1997-05-21  Paul Eggert  <[e-mail]>

	* configure.in (VERSION): Bump to 2.2.91.

	* pch.c (another_hunk):
	Fix bug with computing size of prefix and suffix context
	with ordinary context diffs.  Report malformed patch if a unified diff
	has nothing but context.

	* inp.c (get_input_file):
	Use patch_get, not backup_type, to decide whether to
	get from RCS or SCCS.  Use the word `get' in diagnostics.
	* patch.c (main): Initialize patch_get from PATCH_GET.
	Omit DEFAULT_VERSION_CONTROL hook; it just leads to nonstandarization.
	(longopts, option_help, get_some_switches): Add support for -g, -G.
	(option_help): Add bug report address.
	* common.h (patch_get): New decl.
	* patch.man: Add -g and -G options; use `get' instead of `check out'.

	* version.c (copyright_string): Use only most recent copyright year,
	as per GNU standards.

	* Makefile.in (DISTFILES_PC): Remove pc/quotearg.c.
	* pc/djgpp/config.sed: Remove unnecessary hooks for quotearg and SHELL.

	(malformed): Add decl.
	(there_is_another_patch): Skip inname-detection if skip_rest_of_patch.
	(intuit_diff_type): To determine whether file appears to have been
	deleted, look at replacement, not pattern.
	If there is a mismatch between existence of file and whether the
	patch claims to change whether the file exists, ask whether to
	reverse the patch.
	(another_hunk): New parameter REV specifying whether to reverse the
	hunk.  All callers changed.
	(do_ed_script): Add assertion to ensure input file exists.

	* util.h (create_file): New function.

	All callers changed.
	Quote file names in diagnostics.
	Create parent dir of destination if necessary.

	Unlink destination if FROM is zero.
	(create_file): New function.
	(copy_file): Accept mode of destination, not struct stat.
	All callers changed.
	Use create_file to create file.
	(ok_to_reverse): Moved here from patch.c.  Now accepts format and args;
	all callers changed.
	(mkdir): 2nd arg is now mode_t, for better compatibility.
	(replace_slashes): Ignore slashes at the end of the filename.

	* common.h (noreverse): New decl.
