Rename canonicalize global variable
* src/common.h, src/merge.c (context_matches_file), src/patch.c
(get_some_switches, patch_match), src/pch.c(another_hunk): Rename the
global variable 'canonicalize' to 'canonicalize_ws'.
Patch uses a global variable 'canonicalize' as part of its
implementation of the --ignore-whitespace flag.
In glibc there is a function canonicalize():
https://www.gnu.org/software/libc/manual/html_node/FP-Bit-Twiddling.html#index-canonicalize
Rename the global variable so that it will not conflict.

2016-08-10 Hanno Boeck <hanno@gentoo.org>
Add a missing NULL check in parse_name
* src/util.c (parse_name): parse_c_string() can fail and return NULL.
Check for that so that we won't access the NULL pointer here.
Fix out-of-bounds access to lines in a patch
This bug can trigger with malformed patches.
* src/pch.c (pch_write_line): Avoid out-of-bounds access to
p_line[line][p_len[line] - 1] when p_len[line] is 0.
2016-07-31 Jim Meyering <meyering@fb.com>
tests: use $PATCH rather than hard-coded path
* tests/git-cleanup: Don't hard-code program name.
maint: placate a "make syntax-check" rule
* src/pch.c (set_hunkmax): Don't cast return value of xmalloc.
(grow_hunkmax): Likewise for two uses of realloc that the syntax-check
rule did not detect.
2016-07-31 Jim Meyering <meyering@fb.com>
maint: avoid new warning-errors from gcc-6.1
When configured with --enable-gcc-warnings and gcc-6.1, ...
* src/safe.c (count_path_components): Use _GL_ATTRIBUTE_PURE,
to avoid an error from -Werror=suggest-attribute=pure.
* src/util.h (filename_is_safe): Likewise.
* src/patch.c (main): Placate -Werror=format= by casting
pch_mode's mode_t return type to the "unsigned int" required
to match the %o format string.
* src/patch.c (delete_files): Correct indentation, to avoid
this error from -Werror=misleading-indentation:
patch.c: In function 'delete_files':
patch.c:1816:4: error: this 'if' clause does not guard...
if (verbosity == VERBOSE)

gnulib: update to latest
2016-07-27 Andreas Gruenbacher <agruen@gnu.org>
Fix broken git-style patch behavior
When a git-syle patch is applied, all file modifications are done to
temporary files which are put in place when the patch ends. When a
patch fails, GNU patch was trying to "roll back" to the start. A bug in
that code that lead to accidental file deletion was recently discovered
by Richard Weinberger <richard@nod.at>. Even worse though, GNU patch
should not exhibit this "rollback" behavior in the first place; that's
not what people expect. Instead, the files modified so far should be put
in place.
* src/patch.c (cleanup): Put output files processed successfully
in place instead of trying to "roll back" to the start.
(forget_output_files): Remove obsolete (and broken) function.
* tests/git-cleanup: New broken git-style patch test case that exercises
the cleanup path.
* tests/Makefile.am (TESTS): Add new test case.
Fix inname test case
* src/safe.h (unsafe): New flag to allow turning off safe file
operations.
* src/safe.c (safe_xstat, safe_open, safe_rename, safe_mkdir,
safe_rmdir, safe_unlink, safe_symlink, safe_chmod, safe_lchown,
safe_lutimens, safe_readlink, safe_access): When safe file operations
are turned off, skip safe path traversal. Any symlink checks of the
last path component are still done though.
* src/patch.c (main): When the file to patch is specified on the command
line, turn off safe file operations.
* tests/inname: Fix typo in test.
Add context-format test to XFAIL_TESTS for now
* tests/Makefile.am (XFAIL_TESTS): Add context-format test until someone
gets to fixing it.
2016-03-18 Andreas Gruenbacher <agruen@gnu.org>
Add broken context-format test cases
* tests/context-format: Add context-format test cases from
Mattias Andrée <maandree@member.fsf.org> that patch doesn't parse
correctly.
2015-10-03 Andreas Gruenbacher <agruen@gnu.org>
Don't use a zero-size array in struct symlink
* src/safe.c (struct symlink): Get rid of the zero-size array which is a gcc
extension.
(read_symlink): Adapt to this struct symlink change.
2015-07-20 Andreas Gruenbacher <agruen@gnu.org>
Input file outside current directory: add test case
Patch currently makes sure that input / output files are inside the current
working directory even when the input files are explicitly specified on the
command line (see http://savannah.gnu.org/bugs/?45581).
* tests/inname: Add a test case for this bug.
2015-07-12 Tobias Stoeckmann <tobias@stoeckmann.org>
Terminate readlink string
The function readlink does not nul terminate its result string. safe_readlink
is a wrapper for readlinkat, which has the same behaviour.
* src/util.c (copy_file): Therefore, explicitly set '\0' and reserve one byte
for it. (agruen: Reserve PATH_MAX + 1 bytes instead of only reading PATH_MAX -
1 characters.)
2015-07-08 Tobias Stoeckmann <tobias@stoeckmann.org>
Use xmalloc in bestmatch
* src/bestmatch.h (bestmatch): Use xmalloc instead of malloc to handle
out-of-memory situations.
2015-03-09 Andreas Gruenbacher <agruen@gnu.org>
Don't require traditional patch header after "git --diff"
Reported by Tim Waugh <twaugh@redhat.com>.
* src/pch.c (intuit_diff_type): Don't require a traditional patch header
("--- old\n+++ new/n") after a "git --diff" header; the "git --diff" header
gives us enough information for being able to process subsequent hunks. This
deals with corrupted patches more gracefully.
* tests/corrupt-patch: New test case.
* tests/Makefile.am (TESTS): Add test case.
2015-03-08 Andreas Gruenbacher <agruen@gnu.org>
Use gnulib size_max module
* bootstrap.conf (gnulib_modules): Add size_max.
* configure.ac: Call gl_SIZE_MAX.
2015-03-07 Andreas Gruenbacher <agruen@gnu.org>
Version 2.7.5
* NEWS: Update.
build: update gnulib submodule to latest
Allow absolute symlinks that lead back into the working directory
* src/safe.c (cwd_stat_errno, cwd_stat): stat() result of ".".
(read_symlink): When a symlink is absolute, check if it leads back into the
working directory. If it does, strip off the prefix above the working
directory. If the symlink points to the working directory, return an empty
path.
(traverse_another_path): Recognize empty paths from read_symlink().
* tests/symlinks: Absolute symlink test cases.
2015-03-05 Andreas Gruenbacher <agruen@gnu.org>
Describe better how the dirfd cache works
Use overflow safe arithmetic for counting cache misses
* src/safe.c: We don't need a long counter if we use overflow-safe arithmetic
here.
Also cache resolved symlinks
When resolving a symlink in a pathname, we traverse each path component in the
symlink and cache all of them. At the end, add an additional cache entry for
the symlink itself so that we don't have to resolve the symlink again (even
though this will usually be cached). Skip that if the symlink's parent isn't
in the cache anymore, though.
* src/safe.c (free_cached_dirfd): Remove from parent here instead of in
callers. Move close() to remove_cached_dirfd() instead.
(insert_cached_dirfd): Only insert if the entry's parent still exists; entries
without parent are invalid (see compare_cached_dirfds()); "top-level" entries
have cwd as their parent.
(new_cached_dirfd): New function split off from openat_cached().
(openat_cached): Use new_cached_dirfd() here.
(traverse_another_path): When starting to resolve a symlink, create an unhashed
dirfd cache entry for the symlink lookup result. When the symlink is completely
resolved, add that entry to the cache.
Invalidate child dirfd cache entries when their parent goes away
If we don't do that, a directory could be removed from the cache, a new
directory with the same dirfd could be created, and the entries from the old
directory would appear in the new directory.
* src/safe.c (struct cached_dirfd): Keep track of the children of each dirfd
cache entry.
(remove_cached_dirfd): Remove all the entry's children from the lookup hash,
take them off the list of children, and initialize the children's
children_link. Then, remove the entry itself from its parent. This has no
effect if the entry doesn't have a parent because then, children_link is empty.
(openat_cached): Add new dirfd cache entries to their parent's list of children
and initialize the entry's list of children.
(traverse_another_path): Also initialize cwd's list of children.
Convert lru list into a list_head list
* src/safe.c (struct cached_dirfd): Replace prev and next with a lru_link
list_head.
(lru_list): Turn into a list_head.
(lru_list_add, lru_list_del, lru_list_del_init): Replace by list_add(),
list_del(), list_del_init().
(insert_cached_dirfd): Get to the list entry from the embedded list_head with
the list_entry() macro.
Add list_head based double linked list
* src/list.h: New data structure.
src/Makefile.am (patch_SOURCES): Add list.h.
Invalidate dirfd less aggressively
src/safe.c (safe_rename, safe_rmdir): Only invalidate cache entries when the
underlying sycall succeeds and the entry actually goes away. This keeps the
cache filled upon speculative rmdir when the directory may not be empty, for
example.
2015-03-05 Tim Waugh <twaugh@redhat.com>
Add more path traversal test cases
* tests/symlinks: Add more path traversal test cases.
2015-03-05 Andreas Gruenbacher <agruen@gnu.org>
Move path traversal error reporting into main()
* src/safe.c (traverse_another_path): Don't report errors here.
* src/patch.c (main): Instead, recognize and report them here. Detect when an
output file name is invalid; it doesn't make sense to try creating a
reject file based on the same outbut file name in that case.
Limit the number of path components
src/safe.c (MAX_PATH_COMPONENTS): The maximum number of path components
allowed.
(count_path_components): New function.
(traverse_another_path): Fail if the number of path components gets too high.
Follow directory symlinks within the working directory
* src/safe.c (struct symlink): A symlink to resolve.
(push_symlink, pop_symlink): New functions.
(read_symlink): Create a new symlink stack entry.
(traverse_next): Follow ".." components within the working directory. When
hitting symlinks, "follow" them by reading and returning them.
(traverse_another_path): Recursively traverse symlinks.
Keep track of the directory hierarchy
* src/safe.c (struct cached_dirfd): Add parent pointer. Now that we know our
parent, we no longer need to duplicate its directory file descriptor.
(lookup_cached_dirfd): Don't update the lru list here.
(insert_cached_dirfd): The lru list may now be empty even if the cache is not.
(put_path): New function to put a path back into the lru list.
(openat_cached): Take cached entried off the lru list. They are added back
in put_path().
(traverse_another_path): Put lookup result back into the lru list with
put_path().
2015-02-28 Andreas Gruenbacher <agruen@gnu.org>
Refactor traverse_another_path() and helpers
Prepare for keeping track of the directory hierarchy:
* src/safe.c (traverse_another_path): Pass struct cached_dirfd to
traverse_next().
(traverse_next, openat_cached): Pass through struct cached_dirfd.
Move error reporting out of make_tempfile()
* src/util.c (make_tempfile): Remove error reporting here.
* src/inp.c (plan_b): Readd error reporting here.
* src/patch.c (main): Likewise.
* src/pch.c (open_patch_file): Likewise.
Minor cosmetic changes
* src/safe.c: Minor cosmetic changes
2015-02-22 Andreas Gruenbacher <agruen@gnu.org>
Fix handling of renamed files
When a file has already been renamed, make sure it is not renamed back to its
old name. Reported by Guido Draheim.
* src/patch.c (main): Make sure we never rename a file back to its previous
name. Report when a file was renamed already.
* tests/copy-rename: Add "already renamed" test cases.
2015-02-10 Andreas Gruenbacher <agruen@gnu.org>
Fix symlinks test case on some architectures
* src/safe.c: Include util.h for say(). Define EFTYPE if it isn't defined
already.
(traverse_another_path): When openat fails, also check for EMLINK, EFTYPE, and
ENOTDIR. Change the error message to "file ... is not a directory" and only
skip the rest of the patch instead of aborting.
* tests/symlinks: Update.
2015-02-04 Andreas Gruenbacher <agruen@gnu.org>
Test suite portability fixes
Reported and fixed (mostly) by Christian Weisgerber <naddy@mips.inka.de>:
* tests/deep-directories: Avoid the bash >& redirection operator.
* tests/no-mode-change-git-diff: Instead of "stat -c", use "ls -l sed".
* tests/read-only-files: A redirection failure for a special built-in causes
some shells (FreeBSD sh, OpenBSD sh (pdksh), some bash --posix) to exit, and
the colon command is a special built-in. Perform the redirection in a subshell.
Switch from gen_tempname() to try_tempname()
* Update gnulib submodule to latest.
* src/util.c (try_safe_open_args, try_safe_open): Arguments and callback for
try_tempname().
(make_tempfile): Switch from gen_tempname() to try_tempname().
2015-02-02 Andreas Gruenbacher <agruen@gnu.org>
Check the result of the --follow-symlinks option
* tests/symlinks: Check the result of treating a symlink as a file with
--follow-symlinks.
2015-02-01 Andreas Gruenbacher <agruen@gnu.org>
Link patch with LIB_EACCESS where needed
* src/Makefile.am (patch_LDADD): Add LIB_EACCESS here. At least on Solaris,
faccessat() is implemented through eaccess() which is in the "gen" library.
Fix minor signedness warning
* src/pch.c (intuit_diff_type): Don't assign signed dummy value to unsigned
variable.
Use gnulib faccessat module
* bootstrap.conf (gnulib_modules): Add faccessat.
2015-01-31 Andreas Gruenbacher <agruen@gnu.org>
Upate NEWS
Fix indentation heuristic for context diffs
Diffs can be indented by a variable number of spaces, tabs, or X characters.
Make sure that intuit_diff_type() only accepts context diffs where the first
and second line are indented identically, or else another_hunk() will fail.
* src/pch.c (intuit_diff_type): Remember the indentation of the last line. Only
recognize context diff hunks with the same amount of indentation on the first
and second line.
* tests/garbage: New test case.
* tests/Makefile.am (TESTS): Add test case.
2015-01-31 Quentin Casasnovas <quentin.casasnovas@oracle.com>
patch: git-diff mode: do not change permissions if there isn't an explicit mode change.
tests: add a test case for unwanted mode changes.
test-lib.sh: factorize require_* functions
Since the code is identical when just checking if a utility is present on
the system or not, we can factorize it.
2015-01-31 Andreas Gruenbacher <agruen@gnu.org>
Add test case for patch behind symlink
* tests/symlinks: Add a test case where the patch file itself is in a path that
follows a symbolic link; we want to continue allowing that.
2015-01-31 Tim Waugh <twaugh@redhat.com>
Allow arbitrary symlink targets again
* src/util.c (symlink_target_is_valid): Remove.
(move_file): Remove symlink target checking.
* tests/symlinks: Update test case.
2015-01-31 Andreas Gruenbacher <agruen@gnu.org>
Update list of gnulib modules used
* bootstrap.conf (gnulib_modules): Remove lchmod, lstat, mkdir, readlink,
rename, mkdir, symlink, unlink, utimens. Add fchownat, fchmodat, fstatat,
mkdirat, openat, readlinkat, renameat, symlinkat, unlinkat, utimensat.
* src/util.h: Don't include <utimens.h> anymore.
Use symlink-safe system call replacements
Use the symlink-safe replacements for system calls in many places throughout
the code: In some places this makes patch safe against path traversal attacks;
in other places, it saves the kernel from having to re-traverse the pathnames.
* src/inp.c (plan_b): Use safe_open() + fdopen() instead of fopen().
* src/util.c (copy_attr): Document why we are safe here.
(create_backup): Use safe_open() instead of creat().
2015-01-31 Tim Waugh <twaugh@redhat.com>
Add symlink-safe system call replacements
Add wrappers around system calls that traverse relative pathnames without
following symlinks. Written by Tim Waugh <twaugh@redhat.com> and Andreas
Gruenbacher <agruenba@redhat.com>.
* src/safe.h: Declare functions here.
* src/safe.c: Implement safe_* system call replacements that do not follow
symlinks along pathnames. Pathname components are resolved with openat().
Lookup results are cached to keep the overhead reasonably low.
* tests/deep-directories: New path traversal cache test.
* src/Makefile.am (patch_SOURCES): Add safe.[ch].
* tests/Makefile.am (TESTS): Add new test.
2015-01-31 Andreas Gruenbacher <agruen@gnu.org>
build: update gnulib submodule to latest
2015-01-31 Tim Waugh <twaugh@redhat.com>
Avoid closing file descriptor twice
* src/patch.c (main): Make sure we don't close() outfd after passing it on to
fdopen(): the file descriptor might have been reused in the meantime.
2015-01-29 Andreas Gruenbacher <agruen@gnu.org>
Remove unused variable
* src/pch.c (name_is_valid): Remove unused variable.
2015-01-22 Andreas Gruenbacher <agruen@gnu.org>
Fix the fix for CVE-2015-1196
* src/util.c (filename_is_safe): New function split off from name_is_valid().
(symlink_target_is_valid): Explain why we cannot have absolute symlinks or
symlinks with ".." components for now.
(move_file): Move absolute filename check here and explain.
* tests/symlinks: Put test case with ".." symlink in comments for now.
* NEWS: Add CVE number.
2015-01-21 Andreas Gruenbacher <agruen@gnu.org>
For renames and copies, make sure that both file names are valid
* src/patch.c (main): Allow there_is_another_patch() to set the
skip_rest_of_patch flag.
* src/pch.c (intuit_diff_type): For renames and copies, also check the "other"
file name.
(pch_copy, pch_rename): Now that both names are checked in intuit_diff_type(),
we know they are defined here.
2015-01-20 Andreas Gruenbacher <agruen@gnu.org>
Fail when out of memory in set_hunkmax()
src/pch.c (another_hunk): Call set_hunkmax() from here to make sure it is
called even when falling back from plan A to plan B.
(open_patch_file): No need to call set_hunkmax() anymore.
src/pch.c (set_hunkmax): Fail when out of memory. Make static.
src/pch.h: Remove set_hunkmax() prototype.
Don't try applying hunks at offsets that can't work
* src/patch.c (locate_hunk): Start trying to apply the hunk at the minimum
offset which puts the hunk in the valid range of lines. This will often still
be offset 0.
2015-01-20 Andreas Gruenbacher <andreas.gruenbacher@gmail.com>
Move symlink_target_is_valid() and cwd_is_root()
* src/util.c: Move symlink_target_is_valid() and cwd_is_root() here from
src/pch.c.
2015-01-19 Andreas Gruenbacher <andreas.gruenbacher@gmail.com>
Make sure symlinks don't point outside working directory (CVE-2015-119)
When creating symlinks from git-style patches, make sure the symlinks don't
point above the current working directory. Otherwise, a subsequent patch could
use the symlink to write outside the working directory.
* src/pch.c (symlink_target_is_valid): New function to check for valid symlink
targets.
* src/util.c (move_file): Use symlink_target_is_valid() here.
* tests/symlinks: Add valid and invalid symlink test cases.
2014-11-30 Andreas Gruenbacher <agruen@linbit.com>
Add line number overflow checking
* bootstrap.conf: use intprops module.
* src/common.h: Define LINENUM_MIN and LINENUM_MAX macros.
* src/pch.c (another_hunk): Add line number overflow checking. Based on Robert
C. Seacord's INT32-C document for integer overflow checking and Tobias
Stoeckmann's "integer overflows and oob memory access" patch for FreeBSD.
2014-11-30 Andreas Gruenbacher <agruen@linbit.com>
More savebuf/savestr error handling
* bootstrap.conf: use xmemdup0 module.
* src/pch.c (there_is_another_patch): Use xmemdup0 instead of savebuf when we
cannot recover from out-of-memory situations.
(intuit_diff_type): Likewise, use xstrdup instead of savestr.
(another_hunk): Handle the case when savestr returns NULL.
* src/util.c (fetchname, parse_name): Use xmemdup0 instead of savebuf when we
cannot recover from out-of-memory situations.
Bugs pointed out by Tobias Stoeckmann <tobias@stoeckmann.org>.
2014-11-30 Tobias Stoeckmann <tobias@stoeckmann.org>
savebuf/savestr error handling
* src/patch.c (get_some_switches): The function savebuf (and therefore savestr)
copies strings using malloc. If malloc fails, NULL is returned. This is
intentional behavior so that in case of failure during "plan a" patching, "plan
b" can step in. The return value has to be properly checked for NULL. If the
return value must not be NULL, use xstrdup instead.
2014-11-30 Andreas Gruenbacher <andreas.gruenbacher@gmail.com>
build: update gnulib submodule to latest
* src/merge.c (compute_changes): The TOO_EXPENSIVE heuristic in diffseq has
been removed, including compareseq's find_minimal parameter and the context's
too_expensive limit. Adjust.
2014-11-10 Jean Delvare <jdelvare@suse.de>
Drop useless test in another_hunk()
src/pch.c (another_hunk): This test will always succeed.
2014-10-30 Tobias Stoeckmann <tobias@stoeckmann.org>
Buffer overflow on malicious input file
There is a hard to reach but possible buffer overflow when using
patch with a very large (modified) input file. I doubt you will ever
see this with a 64 bit system, but it's possible with 32 bit:
$ echo hello > file1
$ echo world > file2
$ diff -Nau file1 file2 > file.diff
Nothing fancy so far. Adjust file1 so it contains at least one line that
is 2 GB in size. Larger is fine too, but stay below 4 GB.
$ tr '\0' c < /dev/zero | dd bs=1K count=2097152 of=file1
Now try to patch it.
$ patch -Np0 -i file.diff
Segmentation fault
The issue is in patch's "plan b" strategy (If your system would still
want to use "plan a", force patch to use "plan b" through debug flag).
Plan b writes lines into a temporary file, with equally long lines, so
it can use a buffer mechanism to access them in a kind of randomly
fassion. In order to do that, it retrieves the longest line.
In this example, it will encounter the 2 GB line and stores that as the
longest one. Afterwards it will adjust the tibufsize variable to be
large enough:
for (tibufsize = TIBUFSIZE_MINIMUM; tibufsize < maxlen; tibufsize <<= 1)
/* do nothing */ ;
Due to maxlen's size (2 GB), tibufsize will be SIZE_T_MAX, i.e. 4 GB.
A few lines later it allocates space for the tibuf buffers:
tibuf[0] = xmalloc (2 * tibufsize);
tibuf[1] = tibuf[0] + tibufsize;
This will allocate 0 bytes because tibufsize overflowed. The next
time patch writes into the buffer, a segmentation fault will occur...
Depends on your system how long it takes until that happens. ;)
The fix is simple: Bail out on lines that are too long. Patch already
does that for files that have too many lines.

build: don't use -Werror in AM_INIT_AUTOMAKE
Doing so prevents bootstrapping with bleeding-edge autotools,
because of harmless deprecation warnings (that are not planned
to become hard errors for at least a few years to come). And
unfortunately, options in AM_INIT_AUTOMAKE take precedence over
those given on the command line (this is a long-time wart of
automake).
* configure.ac (AM_INIT_AUTOMAKE): Drop '-Werror' option.

Only warn when trying to modify read-only files
Failing when trying to patch read-only files causes various users of patch to
break. Instead, warn by default and introduce a command line option for
choosing a different behavior.

For git-style patch files, do not output files immediately
In git-style patch files, all patches refer to the initial state of the input
files; files cannot be modified more than once. Implement these semantics by
creating all output files once all patches in the patch file have been
processed.
* src/patch.c (init_files_to_output, output_files): Add prototypes.
(main): Remember which type of patch file we are processing. Initialize the
output files list. Output files of git-style patches once all patches have
been read, or when from git-style to normal patches.
(file_to_output): New struct.
(files_to_output): List of the files to output.
(output_file, output_file_now, output_file_later): Either queue a file for
deletion, remember to output a file later (git-style), or output the file
immediately (normal).
(dispose_file_to_output, init_files_to_output, output_files,
forget_output_files): New functions.
(gl_list_clear): Should be provided by gnulib but isn't.

(intuit_diff_type): Use p_git_diff instead of a local variable.
(pch_git_diff): New function.
Remove invalid symlink test case
* tests/symlinks: Remove test case which deletes and then recreates a symlink:
all patches in a git-style input file must refer to the "before" state; the
test case is invalid.
No longer remember backup files
Remembering backup files was needed because we would have lost track of deleted
files before -- but we don't delete files immediately anymore.
* src/util.c (create_backup_copy): No longer remember backup files.
(create_backup): Likewise; update comment.
(move_file): Update create_backup() call.
* src/util.h (create_backup): Update prototype.

* src/util.h (file_id_type): Add DELETE_LATER and OVERWRITTEN types.
(create_backup, set_file_attributes): Update prototype.

(create_backup): Pass in to_st instead of returning it from create_backup().
This obsoletes the to_errno argument.
(move_file): Determine to_st here and pass it to create_backup(). Remember
when a file is overwritten.
* src/patch.c (output_file): Add to_st parameter. Remember files to delete
instead of deleting them immediately. Pass from-st to create_backup().
(file_to_delete): New struct.
(init_files_to_delete, delete_file_later, delete_files): New functions.
(main): Use init_files_to_delete() and delete_files(). Pass to_st to
output_file() where we already have it.
* src/pch.c (intuit_diff_type): Assume that files which are marked for deletion
don't exist.
Create and delete output files in a single function
* src/patch.c (output_file): New function for creating or deleting an output
file and backing the old file up as needed.
(main): Use the new function.
* src/util.c (move_file): Allow FROM_NEEDS_REMOVAL to be NULL.
Add a type field to entries in the file id cache
* src/util.h (file_id_type): New enum.
* src/util.c (file_id): Add a file_id_type field.
(insert_file_id): Rename from insert_file(); specify a type when inserting a
file id.

(create_backup_copy, create_backup, move_file): Use insert_file_id() instead of
insert_file(), and lookup_file_id() instead of file_already_seen().
* src/patch.c (main): Use lookup_file_id() instead of file_already_seen().
Switch from the `old' gnu quoting style to the 'new' one
* src/common.h, src/patch.c, src/pch.c, src/util.c, src/util.h: Switch from the
`old' gnu quoting style to the 'new' one in messages and comments.

* cfg.mk (local-checks-to-skip): Remove (thus, enable)
sc_copyright_check, now that the gnulib submodule is up to date.
maint: update copyright date year ranges to include 2011
* bootstrap.conf (gnulib_modules): Add update-copyright.
Run "make update-copyright".
build: avoid three gcc warnings
* src/patch.c (mangled_patch): Add "noreturn" attribute.
* src/pch.h (pch_timestamp): Remove ignored "const" attribute.
* src/version.c (XTERN): Remove unused #undef and #define.
tests: temporarily disable failing syntax-check rules
* cfg.mk (local-checks-to-skip): Define, to skip all of the
currently-failing syntax-check rules. We'll reenable them
one by one, as problems are addressed.

* bootstrap.conf (gnulib_modules): Add manywarnings.
* src/Makefile.am (AM_CFLAGS): Use $(WARN_CFLAGS) and $(WERROR_CFLAGS).

Note: unchecked uses of test -ot/-nt also remain.
* tests/empty-files: Use "test C1 && test C2", not "test C1 -a C2"
* tests/merge: Likewise.
* tests/symlinks: Likewise.
* tests/test-lib.sh: Likewise.
maint: allow the sc_prohibit_empty_lines_at_EOF test to pass
* tests/test-lib.sh: Remove empty line at end of file.
maint: remove trailing blanks
* bootstrap.conf: Remove trailing blanks.
* tests/reject-format: Define a dummy, empty variable, and use it in
here-doc to protect required trailing blanks from accidental removal.
* tests/no-newline-triggers-assert: Likewise.
* tests/preserve-c-function-names: Likewise.
* tests/create-delete: Likewise.
* tests/global-reject-files: Complete a sentence that ended in a space.
maint: add some m4 quoting
* m4/setmode.m4 (AC_FUNC_SETMODE_DOS): Use proper M4 quoting.
maint: arrange for the sc_require_config_h_first test to pass
* cfg.mk: New file, to configure maint.mk.
* Makefile.am (EXTRA_DIST): Add, so the new file is distributed.
(config_h_header): Define, to make the sc_require_config_h_first
syntax-check test pass.
* pc/chdirsaf.c: Include <config.h>.
maint: use gnulib's maintainer-makefile module
* bootstrap.conf (gnulib_modules): Add maintainer-makefile.

* Makefile.am (gen-ChangeLog): New rule.
(dist-hook): Depend on it.
(EXTRA_DIST): Add ChangeLog-2011.
* ChangeLog-2011: Renamed from ChangeLog
* ChangeLog: Remove file.
