build: fix build failure due to missing libxattr

2010-01-12T07:06:47Z

Configure is supposed to detect insufficient XATTR support. However, if a system has the required headers, but no library, the configure script would mistakenly enable USE_XATTR. * m4/xattr.m4 (gl_FUNC_XATTR): If the attr_copy_file function is not found, don't set USE_XATTR. Nelson Beebe reported a link failure on RHEL 5.3. Also, do not let the combination of --disable-xattr and a stray LIB_XATTR environment setting perturb the build. * NEWS (Build-related): Mention it.

maint: update all FSF copyright year lists to include 2010

2010-01-01T13:06:47Z

Use this command: git ls-files | grep -v COPYING \ | xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \ build-aux/update-copyright

maint: issue warnings for more missing optional libraries

2009-10-20T16:11:00Z

* README-hacking: Suggest to use ./configure --quiet so that any warnings are easily noticed. * m4/gmp.m4 (cu_GMP): Warn if libgmp is not available. * m4/jm-macros.m4 (coreutils_MACROS): Normalize the libcap warning. * m4/xattr.m4 (gl_FUNC_XATTR): Warn if libattr is not available.

build: use gnulib's isblank module

2009-10-19T05:57:15Z

* bootstrap.conf (gnulib_modules): Add isblank. * src/system.h (isblank): Don't define. * m4/check-decl.m4: Don't check for isblank declaration. * gnulib: Update submodule to latest.

build: don't let environment settings perturb build

2009-10-15T19:03:40Z

Setting the envvars, LIB_FDATASYNC, LIB_XATTR or LIB_CRYPT could cause a configure-time and/or build-time malfunction. Typically, a configure-time function-in-library test is performed via code like this: LIB_VAR= AC_SUBST([LIB_VAR]) prefix_saved_LIBS=$LIBS AC_SEARCH_LIBS([FUNC], [LIB_NAME], [test "$ac_cv_search_FUNC" = "none required" || LIB_VAR=$ac_cv_search_FUNC]) LIBS=$prefix_saved_LIBS However, in each of the files affected by this change, the LIB_VAR= initialization was omitted. Thus, when set in the environment, its value would propagate into generated Makefiles when FUNC is not found in LIB_NAME. * m4/jm-macros.m4 (coreutils_MACROS): Initialize AC_SUBST'd var * m4/lib-check.m4 (cu_LIB_CHECK): Likewise. * m4/xattr.m4 (gl_FUNC_XATTR): Likewise.

copy: allow symlink timestamp preservation on more systems

2009-10-10T21:16:52Z

* src/copy.c (utimens_symlink): Simplify by using lutimens. * m4/jm-macros.m4 (coreutils_MACROS): Drop utimensat; gnulib does this for us. * tests/cp/preserve-slink-time: Recognize lutimes support.

maint: remove unused macros and declarations

2009-10-09T02:30:06Z

* src/system.h (EDQUOT, EISDIR, ENOSYS, EOVERFLOW, F_OK, X_OK) (W_OK, R_OK): Delete; macros provided by gnulib. (includes): Gnulib guarantees both and , in either order. (free, malloc, memchr, realloc, getenv, lseek): Delete, gnulib guarantees these declarations. * m4/check-decl.m4 (gl_CHECK_DECLS): Delete checks now done by gnulib.

rm: use gnulib faccessat

2009-09-11T12:08:58Z

* bootstrap.conf (gnulib_modules): Add faccessat. Replace strdup with strdup-posix. * m4/jm-macros.m4 (coreutils_MACROS): Revert previous change, now that gnulib does it for us. * src/remove.c (write_protected_non_symlink): Use faccessat in more situations.

rm: improve efficiency of rm -r (without -f) from O(N^2) to O(N)

2009-09-11T12:08:58Z

where N is the depth of the deepest hierarchy rm is processing. * src/remove.c (write_protected_non_symlink): Use faccessat to avoid O(N)-per-entry cost of calling euidaccess. * m4/jm-macros.m4 (coreutils_MACROS): Check for faccessat. * NEWS (Improvements): Mention it.

build: fix libcap configure flag handling

2009-09-04T06:48:03Z

* m4/jm-macros.m4 (coreutils_MACROS): The code to handle configure-time enabling or disabling of libcap support was broken. It would treat any libcap configure option as --disable-libcap because it doesn't check $enableval at all. This change makes sure we do the sane thing: --disable-libcap -> disable and don't run any tests --enable-libcap -> run tests and fail if not found default -> run tests and warn if not found
