tests: avoid dependence on file layout for cp sparse check

2023-04-13T19:19:18Z

* tests/cp/sparse-2.sh: Don't depend on the copy taking <= allocation of the source. Instead leverage --debug to check that zero detection is being enabled.

tests: avoid non portable brace expansion

2023-04-10T17:54:19Z

* tests/cp/backup-dir.sh: Avoid non portable brace expansion which is not supported by FreeBSD or Solaris shells at least.

cp,mv: issue "skipped" messages when skipping files

2023-04-08T11:11:58Z

* NEWS: Mention the change in behavior to issue a "not replaced" error diagnostic with -n, and the "skipped" message with -v. * src/copy.c (copy_internal): Adjust to output the "skipped" messages depending on -i, -n, -u. * tests/cp/cp-i.sh: Adjust accordingly. * tests/mv/mv-n.sh: Likewise.

cp: fix --backup with subdirectories

2023-04-04T11:00:11Z

* gnulib: Reference the latest gnulib including the fix to the backupfile module in commit 94496522. * tests/cp/backup-dir.sh: Add a test to ensure we rename appropriately when backing up through subdirs. * NEWS: Mention the bug fix. Fixes https://bugs.gnu.org/62607

test: avoid a test hang on Hurd

2023-03-15T18:11:00Z

* tests/cp/sparse-to-pipe.sh: Protect the cp call seen to hang on Hurd/i686 with a timeout. Reported By: Bruno Haible

tests: determine if SEEK_HOLE is enabled

2023-02-24T00:35:18Z

Upcomming gnulib changes may disable SEEK_HOLE even if the system supports it, so dynamically check if we've SEEK_HOLE enabled. * init.cfg (seek_data_capable_): SEEK_DATA may be disabled in the build if the system support is deemed insufficient, so also use `cp --debug` to determine if it's enabled. * tests/cp/sparse-2.sh: Adjust to a more general diagnostic. * tests/cp/sparse-extents-2.sh: Likewise. * tests/cp/sparse-extents.sh: Likewise. * tests/cp/sparse-perf.sh: Likewise.

cp,install,mv: add --debug to explain how a file is copied

2023-02-24T00:35:18Z

How a file is copied is dependent on the sparseness of the file, what file system it is on, what file system the destination is on, the attributes of the file, and whether they're being copied or not. Also the --reflink and --sparse options directly impact the operation. Given it's hard to reason about the combination of all of the above, the --debug option is useful for users to directly identify if copy offloading, reflinking, or sparse detection are being used. It will also be useful for tests to directly query if these operations are supported. The new output looks as follows: $ src/cp --debug src/cp file.sparse 'src/cp' -> 'file.sparse' copy offload: yes, reflink: unsupported, sparse detection: no $ truncate -s+1M file.sparse $ src/cp --debug file.sparse file.sparse.cp 'file.sparse' -> 'file.sparse.cp' copy offload: yes, reflink: unsupported, sparse detection: SEEK_HOLE $ src/cp --reflink=never --debug file.sparse file.sparse.cp 'file.sparse' -> 'file.sparse.cp' copy offload: avoided, reflink: no, sparse detection: SEEK_HOLE * doc/coreutils.texi (cp invocation): Describe the --debug option. (mv invocation): Likewise. (install invocation): Likewise. * src/copy.h: Add a new DEBUG member to cp_options, to control whether to output debug info or not. * src/copy.c (copy_debug): A new global structure to unconditionally store debug into from the last copy_reg operations. (copy_debug_string, emit_debug): New functions to print debug info. * src/cp.c: if ("--debug") x->debug=true; * src/install.c: Likewise. * src/mv.c: Likewise. * tests/cp/debug.sh: Add a new test. * tests/local.mk: Reference the new test. * NEWS: Mention the new feature.

tests: fix exit status check in cp -u test

2023-02-03T16:38:55Z

* tests/cp/preserve-link.sh: This should have been part of commit v9.1-134-g01503ce73.

cp,mv: skipping due to -u is success, not failure

2023-01-31T17:25:25Z

This reverts the previous change, so that when a file is skipped due to -u, this is not considered a failure. * doc/coreutils.texi: Document this. * src/copy.c (copy_internal): If --update says to skip, treat this as success instead of failure. * tests/mv/update.sh, tests/cp/slink-2-slink.sh: Revert previous change, to match reverted behavior.

cp,ln,mv: when skipping exit with nonzero status

2023-01-31T16:54:37Z

* NEWS, doc/coreutils.texi: Document this. * src/copy.c (copy_internal): * src/ln.c (do_link): Return false when skipping action due to --interactive or --no-clobber. * tests/cp/cp-i.sh, tests/cp/preserve-link.sh: * tests/cp/slink-2-slink.sh, tests/mv/i-1.pl, tests/mv/i-5.sh: * tests/mv/mv-n.sh, tests/mv/update.sh: Adjust expectations of exit status to match revised behavior.
