| | | | | | | | | | | | | | | ///aaa/bbb and /aaa/bbb/ are the same paths. This is important especially with NFS where number of slashes are not the same in the /proc/self/mountinfo and fstab or utab.

* lib/strutils: fix string_add_to_idarray() int vs. size_tKarel Zak2015-04-221-1/+1
| | | | | | | | | | | | | | | | | | | | The function uses "int" as argument, but for array size (and index) is better to use unsigned type (size_t). If we mix "size_t" in util (e.g. fdisk) and "int" in lib/strutils.c then result is unexpected behavior on ppc64. # sfdisk --list -o DEVICE,START,SIZE /dev/sdb Disk /dev/sdb: 50 MiB, 52428800 bytes, 102400 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 32768 bytes Disklabel type: gpt Disk identifier: 3B8559DB-33AF-43E9-BEFC-C331D829B539 lt-sfdisk: libfdisk/src/label.c:178: fdisk_label_get_field: Assertion `id > 0' failed.

| | | | | | | | This function currently sets the low or high values to 0 when the string doesn't contain a value, like '123:' or ':123'. In order to make it more flexible, we allow it to be passed an arbitrary value. Signed-off-by: Davidlohr Bueso <dave@gnu.org>

* lib: [strutils] general purpose string handling functionsDavidlohr Bueso2010-11-231-0/+26
This patch replaces a few functions used throughout the source: * Renames getnum (from schedutils) to strtol_or_err * Moves strtosize (from lib/strtosize.c) * Moves xstrncpy (from include/xstrncpy.h) * Adds strnlen, strnchr and strndup if not available (remove it from libmount utils) A few Makefile.am files were modified to compile accordingly along with trivial renaming in schedutils source code.
