* 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.
* m4/xattr.m4 (gl_FUNC_XATTR): Only enable USE_XATTR if both attr_copy_file()
and attr_copy_action() are defined.
* src/util.c (copy_attr_check): No fallback needed if attr_copy_action() is not
defined.
* m4/xattr.m4 (gl_FUNC_XATTR): Check if attr_copy_action() is defined.
* src/util.c: If attr_copy_action() doesn't exist, fall back to the default
copy_attr_file() behavior of copying most extended attributes except ACLs.
Fixes the bug that more than one numbered backup would be created when a patch
file deletes and recreates a file.
* bootstrap.conf (gnulib_modules): Add linked-list and xlist modules.
* src/util.h (file_id_type): Add DELETE_LATER and OVERWRITTEN types.
(create_backup, set_file_attributes): Update prototype.
(insert_file_id): Add prototype.
* src/util.c (insert_file_id): Export.
(set_file_attributes, create_backup_copy): Make the st argument const.
(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.
Mark functions as pure of const, per recommendations enabled by
new gcc -W options. Apply _GL_ATTRIBUTE_PURE and _GL_ATTRIBUTE_CONST.
* src/common.h: Apply new function attributes.
* src/pch.c: Likewise.
* src/pch.h: Likewise.
* src/util.c: Likewise.
* src/util.h: Likewise.
* configure.ac: Use -Wno-format-nonliteral.
* m4/.gitignore: Update.
* gnulib: Update to latest.
* cfg.mk: Exempt src/util.c from two tests, to avoid new
"make syntax-check" failures.
* configure.ac: Remove AC_SYS_LARGEFILE, subsumed by ...
* bootstrap.conf (gnulib_modules): ...this. Use largefile module.
* gnulib: Update to latest.
This is useful to Mac OS X 10.5 users if/when configure
is generated using autoconf prior to v2.68-80-gdb2f2e0.
* bootstrap: Update from gnulib.
* cfg.mk (local-checks-to-skip): Remove (thus, enable)
sc_copyright_check, now that the gnulib submodule is up to date.
* src/patch.c (main): Set all file attributes of the temporary output
file before renaming it over the final output file (possibly replacing
the input file). Pass the input file name to set_file_attributes().
* src/util.c (set_file_attributes): When enabled (USE_XATTR), also
copy extended attributes including attributes which define
permissions.
(copy_attr_error, copy_attr_quote, copy_attr_free, copy_attr_check,
copy_attr): Helper functions for copying extended attributes.
* m4/xattr.m4 (gl_FUNC_XATTR): Import from coreutils.
* src/Makefile.am (patch_LDADD): Add $(LIB_XATTR) here.
* bootstrap.conf: Use the gnulib verror module.
* configure.ac: Add automake and gnulib macros, replace several
obsolete macros.
* Makefile.am, lib/Makefile.am, src/Makefile.am, tests/Makefile.am:
Add for automake.
* autogen.sh, INSTALL, Makefile.in, mkinstalldirs, update-version.sh:
Obsolete; remove.
* README-hacking: Import from diffutils, replace cvs with git.
* build-aux: Move gnulib auxiliary files here from the top-level
directory.
* gnulib: Add gnulib git submodule.
* bootstrap, bootstrap.conf: Import from gnulib and adjust.
* gl/lib: Remove gnulib files from the repository; they are now
imported into lib/ from gnulib as needed.
* tests/test-lib.sh: Use $abs_top_builddir exported from
tests/Makefile.am here instead of $PWD.
* m4/utimbuf.m4: This macro has been removed from gnulib. Add it here
for now; this will be replaced by gnulib's utimens module soon.
