tests: avoid spurious failure when SIZE_MAX is 2^32-1

2013-05-27T22:02:50Z

* tests/split/line-bytes.sh: Since we've limited virtual memory to 20MB, choose a smaller size, 1GiB (which is <= SIZE_MAX) rather than 1EiB, which is larger than SIZE_MAX on 32-bit systems. I confirmed that this test still fails when the split.c-modifying part of v8.21-58-gfec363c is backed out.

split: with --line-bytes only allocate memory as needed

* src/split.c (line_bytes_split): Rewrite to only buffer when necessary. I.E. only increase the buffer when we've already lines output in a split and we encounter a line larger than the input buffer size, in which case a hold buffer will be increased in increments of the input buffer size. (lines_rr): Use the more abstract xalloc_die() just like we did in line_bytes_split(), rather than explicitly printing the "memory exhausted" message and exiting. * tests/split/line-bytes.sh: Add a new test for this function which previously had no test coverage. * tests/local.mk: Reference the new test. * NEWS: Mention the improvement. Fixes http://bugs.gnu.org/13537
