* tests/split/l-chunk-root.sh: Fix recently introduced typo.
|
|
* tests/split/l-chunk.sh: Move the "expensive" portion to ...
* tests/split/l-chunk-root.sh: .. A new test split from l-chunk.sh
which uses an isolated TMPDIR, rather than exhausting /tmp,
as that gives false positive failures with some other coreutils tests
like tac-2-nonseekable.sh and shuf-reservoir.sh at least.
* tests/local.mk: Reference the new test.

Note mktemp --suffix has the same inconsistency,
but mktemp -d does support creating dirs
so probably best to leave that as is.
* src/split.c (main): Check for trailing /.

* README: State that DEBUG=yes is particularly useful with perl tests.
* tests/split/l-chunk.sh: Use the more standard $DEBUG variable
rather than an internal $DEBUGGING variable.

* tests/misc/read-errors.sh: Exercise more modes of
various utilities for better read error coverage.
* tests/split/fail.sh: Remove part refactored into the above test.

* bootstrap.conf (gnulib_modules): Add free-posix, tmpfile.
* src/split.c (copy_to_tmpfile): New function.
(input_file_size): Use it to split larger files when sizes cannot
easily be determined via fstat or lseek. See Bug#61386#235.

very expensive since they exhaust /tmp.

Prefer signed types to uintmax_t, as this allows for better
runtime checking with gcc -fsanitize=undefined.
Also, when an integer overflows just use the maximal value
when the code will do the right thing anyway.
* src/split.c (set_suffix_length, bytes_split, lines_split)
(line_bytes_split, lines_chunk_split, bytes_chunk_extract)
(lines_rr, parse_chunk, main):
Prefer a signed type (typically intmax_t) to uintmax_t.
(strtoint_die): New function.
(OVERFLOW_OK): New macro. Use it elsewhere, where we now allow
LONGINT_OVERFLOW because the code then does the right thing on all
practical platforms (they have int wide enough so that it cannot
be practically exhausted). We can do this now that we can safely
assume intmax_t has at least 64 bits.
(parse_n_units): New function.
(parse_chunk, main): Use it.
(main): Do not worry about integer overflow when the code
will do the right thing anyway with the extreme value.
Just use the extreme value.
* tests/split/fail.sh: Adjust to match new behavior.
|
|
* src/split.c (input_file_size): Do not bother with lseek if the
initial read probe reaches EOF, since the file size is known then.
This works better on macOS, which doesn’t allow lseek on /dev/null.
Do not special-case size-zero files, as the issue can occur
with any size file (though /proc files are the most common).
If the current position is past end of file, treat this as
size zero regardless of whether the file has a usable st_size.
Pass through lseek -1 return values rather than using ‘return -1’;
this makes the code a bit easier to analyze (and a bit faster).
Avoid undefined behavior if the size calculation overflows.
(lines_chunk_split): Do not bother with lseek if it would have
no effect if successful. This works better on macOS, which
doesn’t allow lseek on /dev/null.
* tests/split/l-chunk.sh: Adjust to match fixed behavior.
|
|
* src/split.c (bytes_split): New arg REM_BYTES.
Use this to split more evenly. All callers changed.
(lines_chunk_split, bytes_chunk_extract):
Be consistent with new byte_split.
* tests/split/b-chunk.sh, tests/split/l-chunk.sh: Test new behavior.

commit v8.25-4-g62e7af0 introduced the issue as it
broke out of the processing loop irrespective of
the value of new_file_flag which was used to indicate
a finite number of filters or not.
For example, this ran forever (as it should):
$ yes | split --filter="head -c1 >/dev/null" -b 1000
However this exited immediately due to EPIPE being propagated
back through cwrite and the loop not considering new filters:
$ yes | split --filter="head -c1 >/dev/null" -b 100000
Similarly processing would exit early for a bounded number of
output files, resulting in empty data sent to all but the first:
$ truncate -s10T big.in
$ split --filter='head -c1 >$FILE' -n 2 big.in
$ echo $(stat -c%s x??)
1 0
I was alerted to this code by clang-analyzer,
which indicated dead assigments, which is often
an indication of code that hasn't considered all cases.
* src/split.c (bytes_split): Change the last condition in
the processing loop to also consider the number of files
before breaking out of the processing loop.
* tests/split/filter.sh: Add a test case.
* NEWS: Mention the bug fix.

ASAN reported this error for: split -n2/3 /dev/null
ERROR: AddressSanitizer: negative-size-param: (size=-1)
#0 0x7f0d4c36951d in __asan_memmove (/lib64/libasan.so.2+0x8d51d)

#2 0x404e06 in bytes_chunk_extract src/split.c:988
#3 0x404e06 in main src/split.c:1626
Specifically there would be invalid memory access
and subsequent processing if the chunk to be extracted
was beyond the initial amount read from file (which is
currently capped at 128KiB). This issue is not in a
released version, only being introduced in commit v8.25-4-g62e7af0
* src/split.c (bytes_chunk_extract): The initial_read != SIZE_MAX
should have been combined with && rather than ||, but also this
condition is always true in this function so remove entirely.
* tests/split/b-chunk.sh: Add a test case.
Fixes http://bugs.gnu.org/25003
|
|
* tests/split/filter.sh: Use OFF_T_MAX-1 rather than OFF_T_MAX
as the size of a test file, to avoid false failure on an XFS file
system (or any file system permitting a file of size OFF_T_MAX).
Reported as http://bugs.gnu.org/22931
|
|
* src/split.c (lines_rr): Reinstate the conditional
setting of the WROTE boolean, as otherwise split -n r/1 would
consume all input when all --filter commands are stopped.
There was a test in place to check for this, but
it was incorrect as detailed below.
(input_file_size): Immediately disallow --number with
non seekable inputs, as such an invocation is not currently
generally supported and will fail as the data overflows
the internal buffer.
* tests/split/l-chunk.sh: Adjust to again disallow -n /dev/zero.
Also change all '&& fail=1' checks to use the 'returns_ 1' form.
* tests/split/filter.sh: Change the no longer supported /dev/zero
case to a regular $OFF_T_MAX file (supported on XFS for example).
Also fix the timeout(1) commands so they're not subject to
pipefail issues.

Problem reported by Nelson H.F. Beebe in: http://bugs.gnu.org/22624
Other problems also fixed: basically, the code got confused because
GNU/Linux reports that /dev/zero has size zero.
* src/split.c (input_file_size): Now takes struct stat *, not just
size. Always store the first buffer. All callers changed. Treat
/dev/zero as an infinitely-large file, both on GNU/Linux where
fstat and lseek say its size is zero, and on GNU/Hurd where they
say the size is OFF_T_MAX.
(cwrite): Return true on success.
(bytes_split): Don't try to read past EOF, and stop if a write fails.
(lines_rr): Omit stray check for ignorable errno.
(main): Get file size only when n_units > 1, since that's the only
time it is needed. Defer most of the work to input_file_size.
* tests/split/l-chunk.sh: Adjust tests to match new behavior
on oddball inputs.

Quote file names using the "shell-escape" or "shell-escape-always"
methods, which quote as appropriate for most shells,
and better support copy and paste of presented names.
The "always" variant is used when the file name is
embedded in an error message with surrounding spaces.
* cfg.mk (sc_error_shell_quotes): A new syntax check rule
to suggest quotef() where appropriate.
(sc_error_shell_always_quotes): Likewise for quoteaf().
* src/system.h (quotef): A new define to apply shell quoting
when needed. I.E. when shell character or ':' is present.
(quoteaf): Likewise, but always quote.
* src/*.c: Use quotef() and quoteaf() rather than quote()
where appropriate.
* tests/: Adjust accordingly.

When configured with either 'symlinks' or 'shebangs' as value for
the --enable-single-binary option, tests based on `ulimit -v` are
skipped. The reason is that the multicall 'coreutils' binary requires
much more memory due to shared libraries being loaded, and the size of
the 'date' binary (~290KiB) compared to the multicall binary (~5MiB),
of course. Finally, in the case of 'shebangs', the starting shell
requires more memory, too
Instead of using hard-coded values for the memory limit, use an
adaptive approach: first determine the amount of memory for a similar,
yet more trivial invocation of the command, and then do the real test
run using that limit (plus some buffer in some cases).
* init.cfg (require_ulimit_v_): Remove function.
(get_min_ulimit_v_): Add function to determine the minimum memory limit
required for a given command in an adaptive way.
* cfg.mk (sc_prohibit_test_ulimit_without_require_): Change the name
of the above function in the syntax-check rule.
* tests/cp/link-heap.sh: Use the above function to determine the
minimum memory required to run a command simpler than in the real test
run. Use that limit plus a buffer there. While at it, change to list
of commands in the subshell to fail also if the beginning `ulimit -v`
fails.

use cases for the FROM parameter, and the consequences on
the suffix length determination.

FROM parameter in the suffix width calculation, when it's

* src/split.c (eolchar): A new variable to hold
the separator character (unibyte for now).
This is reference throughout rather than hardcoding '\n'.
(usage): Describe the new --separator option, and
mention records along with lines so there is no ambiguity
that all options treat lines and records equivalently.
(main): Have -t update eolchar, or default to '\n'.
* tests/split/record-sep.sh: New test case.
* tests/local.mk: Reference the new test.
* doc/coreutils.texi (split invocation): Document the new option.
Adjust --lines, --line-bytes, --number=[lr]/... to mention
they pertain to records if --separator is specified.
* NEWS: Mention the new feature.

Many tests use `program ... && fail=1` to ensure expected
error situations are indicated. However that would mask
an unexpected exit (like a crash). Therefore explicitly
check the expected exit code.
Note where error messages are also verified, the extra
protection is not added.
* tests/init.sh (returns_): A new helper function to
check the return code of a command, and used
throughout the tests.
* cfg.mk (sc_prohibit_and_fail_1): Add a syntax check
to avoid new instances of this issue.
