From 8b7b7f75d91f7bac323dd6a370aeb3e9c5c4a7d5 Mon Sep 17 00:00:00 2001 From: Mark Wielaard Date: Fri, 6 Nov 2015 11:22:38 +0100 Subject: Add LFS support for fts functions (bug 11460) fts didn't have large-file support yet and fts.h had an #error preventing usage when _FILE_OFFSET_BITS was set. This required nasty workarounds for programs using fts with LFS. This patch implements LFS support for fts by adding FTS64 and FTENT64 variants plus fts64 functions. Which are simple aliases for 64bit off_t arches. Also includes a simple testcase for some of the fts functions with or without LFS enabled. [BZ #11460] * io/Makefile (routines): Add fts64. (tests): Add tst-fts and tst-fts-lfs. (CFLAGS-fts64.c): New. * io/Versions (GLIBC_2.23): New. * io/fts.c: Replace FTS with FTSOBJ, FTSENT with FTSENTRY. Use function defines FTS_OPEN, FTS_CLOSE, FTS_READ, FTS_SET and FTS_CHILDREN. Define FTSOBJ, FTSENTRY, FTS_OPEN, FTS_CLOSE, FTS_READ, FTS_SET, FTS_CHILDREN, INO_T, STAT and LSTAT if necessary. * io/fts.h (FTS64): New if _USE_LARGEFILE64. (FTSENT64): Likewise.
