maint: handle file sizes more reliably

2012-05-10T09:02:42Z

Problem reported by Samuel Thibault in . * NEWS: Document this. * src/dd.c (skip): Handle skipping past EOF on shared or typed memory objects the same way as with regular files. (dd_copy): It's OK to truncate shared memory objects. * src/du.c (duinfo_add): Check for overflow. (print_only_size): Report overflow. (process_file): Ignore negative file sizes in the --apparent-size case. * src/od.c (skip): Fix comment about st_size. * src/split.c (main): * src/truncate.c (do_ftruncate, main): On files where st_size is not portable, fall back on using lseek with SEEK_END to determine the size. Although strictly speaking POSIX says the behavior is implementation-defined, in practice if lseek returns a nonnegative value it's a reasonable one to use for the file size. * src/system.h (usable_st_size): Symlinks have reliable st_size too. * tests/misc/truncate-dir-fail: Don't assume that getting the size of a dir is not allowed, as it's now allowed on many platforms, e.g., GNU/Linux.

du: fix -x: don't ignore non-directory arguments

2012-03-08T12:04:09Z

Surprise! "du -x non-DIR" would print nothing. Note that the problem arises only when processing a non-directory specified on the command line. Not surprisingly, "du -x" still works as expected for any directory argument. When performing its same-file-system check, du may skip an entry only if it is at fts_level 1 or greater. Command-line arguments are at fts_level == 0 (FTS_ROOTLEVEL). * src/du.c (process_file): Don't use the top-level FTS->fts_dev when testing for --one-file-system (-x). It happens to be valid for directories, but it is always 0 for a non-directory. * tests/du/one-file-system: Add tests for this. * NEWS (Bug fixes): Mention it. Reported by Daniel Stavrovski in http://bugs.gnu.org/10967. Introduced by commit v8.14-95-gcfe1040.

maint: use single copyright year range

maint: src/*.[ch]: convert more `...' to '...'

2012-01-09T20:51:59Z

Run this (twice): git grep -E -l '`.+'\' src/*.[ch] \ |xargs perl -pi -e 's/`(.+?'\'')/'\''$1/'

maint: src/*.c: change remaining quotes (without embedded spaces)

2012-01-09T20:50:08Z

Run this (twice): git grep -E -l '`[^ ]+'\' src/*.c \ |xargs perl -pi -e 's/`([^ ]+'\'')/'\''$1/'

maint: convert `...' to '...' in --help output

2012-01-09T20:50:08Z

All affected lines end with \ or \n\, so run this command until it produces no new changes (4 times): git grep -E -l '`[^ ]+'\''.*\\' src \ |xargs perl -pi -e 's/`([^ ]+'\''.*\\)/'\''$1/'

maint: use new emit_try_help in place of equivalent fprintf

2012-01-07T15:54:26Z

Run this command: perl -0777 -pi -e \ 's/fprintf \(stderr, _\("Try `%s --help.*\n.*;/emit_try_help ();/m'\ src/*.c

maint: update all copyright year number ranges

2012-01-01T09:04:06Z

du: -x should not count files in other file systems

2011-12-15T02:04:05Z

This fixes Bug#10293, which I guess was introduced in commit 95c948b06a dated 2003-10-02. * NEWS: Document fix. * src/du.c (process_file): Don't count files in different file systems if -x is given. * tests/du/one-file-system: Test for this bug.

maint: use stat-size module from gnulib

2011-06-13T10:39:22Z

* gnulib: Update to latest. * src/system.h: Definitions of ST_* macros have moved into the gnulib module stat-size (specifically, the header file stat-size.h), so remove them from here. * src/truncate.c: Include stat-size.h. * src/stat.c: Likewise. * src/shred.c: Likewise. * src/ls.c: Likewise. * src/du.c: Likewise. * src/ioblksize.h: New file. Move definition of io_blksize out of system.h so that system.h does not have to include stat-size.h. * src/cat.c: Include ioblksize.h. * src/split.c: Likewise. * src/copy.c: Include both stat-size.h and ioblksize.h. * src/Makefile.am (noinst_HEADERS): Add ioblksize.h.
