yes: make operation independent of pipe size

2026-04-17T15:15:08Z

* src/yes.c (splice_write): Always drain what we've written to an internal pipe, so there is no possibility of vmsplice() blocking. I.e., be defensive in the case that fcntl() fails, and our default buffer size (currently 16kiB) is larger than the pipe. https://github.com/coreutils/coreutils/issues/253

build: fix build failure on AIX

2026-04-16T21:05:13Z

* m4/jm-macros.m4: AIX has a splice() function for TCP, so check for vmsplice() instead. * src/splice.h: Define HAVE_SPLICE if vmsplice available. Reported by Bruno Haible.

cksum: fix --length validation on 32 bit platforms

2026-04-16T19:40:34Z

Fix an unreleased issue due to the recent change to using idx_t in commit v9.10-91-g02983e493 * src/cksum.c (main): Limit the possible return to the range supported by idx_t. Reported by Bruno Haible.

df: improve detection of duplicate entries

2026-04-15T11:56:16Z

Do not compare only with the latest entry for given device id but also all previously saved entries with the same id. * src/df.c (struct devlist): Add next_same_dev struct member. (filter_mount_list): Iterate over next_same_dev to find duplicates. * tests/df/skip-duplicates.sh: Add test cases. * NEWS: Mention the improvement. https://redhat.atlassian.net/browse/RHEL-5649

mktemp: prefer rmdir and unlink to remove

2026-04-11T16:58:13Z

This avoids the following behavior: $ strace -e silence=exit -e trace=unlink,rmdir \ mktemp -d > /dev/full unlink("/tmp/tmp.ZBuPmS9ZGD") = -1 EISDIR (Is a directory) rmdir("/tmp/tmp.ZBuPmS9ZGD") = 0 mktemp: write error: No space left on device In the above invocation we know that we created a directory, so we should not remove a regular file that must have been created by another process: $ strace -e silence=exit -e trace=unlink,rmdir \ ./src/mktemp -d > /dev/full rmdir("/tmp/tmp.hGbME1HmJr") = 0 mktemp: write error: No space left on device * src/mktemp.c (main): Prefer rmdir and unlink depending on whether we created a directory or regular file. * bootstrap.conf (gnulib_modules): Remove the remove module.

cat: avoid redundant pipe creation and resizing

2026-04-11T05:44:22Z

* src/cat.c (splice_cat): Don't bother resizing input as it generally doesn't help perf, and also save an fstat per input. Don't close the intermediate pipe once created, unless there is an error reading from it. Co-authored-by: Pádraig Brady

env: avoid locking standard output for each printed variable

2026-04-10T04:59:12Z

* src/env.c (main): Use fputs and putchar instead of printf.

printenv: avoid locking standard output for each printed variable

2026-04-10T04:53:28Z

* src/printenv.c (main): Use fputs and putchar instead of printf.

maint: remove last remaining assert()

2026-04-09T20:36:43Z

* src/split.c (bytes_chunk_extract): Prefer affirm to assert, as it allows for better static checking when compiling with -DNDEBUG.

maint: cat: avoid coverity NULL dreference warning

2026-04-09T20:25:27Z

* src/cat.c (ensure_buf_size): Affirm we won't return NULL;
