maint: stzncpy: restrict pointer parameters

2012-07-21T10:08:31Z

* src/system.h (stzncpy): Add "restrict" attribute to each pointer parameter and note in the comment that the buffers must not overlap.

pinky,who: fix bug in latest change

2012-07-15T17:11:45Z

* src/system.h (stzncpy): New function. * src/pinky.c (print_entry): Use stzncpy, not stpncpy. The latter does not NUL-terminate. I assumed that strncpy was the only function with such a horrible API. Today I learned that stpncpy also may not NUL-terminate its result. The bugs were introduced in commit v8.17-48-gf79263d. * src/who.c (print_user): Likewise. Thanks to Erik Auerswald for spotting my error.

maint: refactor common mode bits used to create files

2012-06-22T10:17:38Z

* src/system.h (MODE_RW_UGO): The new refactored define (666). * src/mkfifo.c: Use the new define. * src/mknod.c: Likewise. * src/split.c: Likewise. * src/system.h: Likewise. * src/touch.c: Likewise. * src/truncate.c: Likewise. Suggested-by: Jim Meyering

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.

maint: new function: usable_st_size

maint: ensure PATH_MAX is set correctly

2012-03-22T12:12:26Z

This reverts part of commit v8.12-103-g54cbe6e. * src/system.h: Include gnulib's pathmax.h to honor system specific limits, and then we set PATH_MAX only if needed. Note pathmax.h no longer uses pathconf ("/", _PC_PATH_MAX). Note I didn't reinstate the comments about limits.h inclusion order, because pathmax.h includes limits.h anyway.

maint: refactor copy to use is_nul()

2012-03-06T23:43:21Z

* src/dd.c: Move is_nul() from here to ... * src/system.h: ... here * src/copy.c (sparse_copy): Adjust to use the refactored is_nul()

doc: clarify a comment in system.h

2012-02-24T11:22:52Z

* src/system.h (STRNCMP_LIT): Clarify comment. Suggested by Bruno Haible.

maint: use single copyright year range

2012-01-27T10:35:24Z

Run "make update-copyright".

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