2010-01-01maint: update all FSF copyright year lists to include 2010Jim Meyering
Use this command: git ls-files | grep -v COPYING \ | xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \ build-aux/update-copyright
2009-09-23maint: Use logical rather than bitwise operators on boolsPádraig Brady
This is because bitwise operators are: - confusing and inconsistent in a boolean context - non short circuiting - brittle in C89 where bool can be an int (so > 1)
2009-09-21doc: mention the texinfo documentation in --helpPádraig Brady
* src/system.h: Rename emit_bug_reporting_address() to emit_ancillary_info() and update it to not print the translation project address in en_* locales, and _do_ print it in the 'C' (and other) locales so that it's included in the default man page. Also mention how to invoke the texinfo documentation for each command. Also move the "hard-locale.h" include to the 8 files that now use it. * man/help2man: Strip the newly added texinfo reference from the --help output as a more verbose version is already added by help2man. Suggestion from C de-Avillez

2009-03-11cat: Fix immediate output of processed dataPádraig Brady
Introduced by commit 790892db, 2006-06-08 "Ensure that cat works ...". * NEWS: Mention the bugfix. * src/cat.c (cat): Fix the typo which stopped the writing of processed data before a blocking read() is done. * tests/misc/cat-buf: Add to ensure processed data is not buffered. * tests/Makefile.am: Reference the new test.
2009-03-11cat,cp,mv,install,split: Set the minimum IO block size used to 32KiBPádraig Brady
This is following on from this change: [02c3dc9d 2008-03-06 cat: use larger buffer sizes ...] which increased the IO block size used by cat by 8 times, but also capped it at 32KiB. * NEWS: Mention the change in behavior. * src/system.h: Add a new io_blksize() function that returns the max of ST_BLKSIZE or 32KiB, as this was seen as a good value for a minimum block size to use to get good performance while minimizing system call overhead. * src/cat.c: Use it. * src/copy.c: ditto * src/split.c: ditto
2009-03-06cat: use larger buffer sizes to reduce read/write-syscall overheadJim Meyering
* src/cat.c (max): Remove definition. Use MAX from system.h instead. (compute_buffer_size): New function to compute the input and output buffer sizes, which are now set at 8 times st_blksize with a maximum of 32KiB. Previously the typical block sizes used were 1KiB for pipes and 4KiB for files, and now will be 8KiB and 32KiB respectively. (main): Use it. This change can double throughput on modern systems. For timings, see http://article.gmane.org/gmane.comp.gnu.core-utils.bugs/16040 Suggestion from Tzvi Rotshtein.

2008-06-16remove redundant const directivesJim Meyering
In 1463824d8e7f72c31f1d803d7cfe2b608ccafc5c, I added some missing "const" directives, as well as some new, redundant ones. This removes the redundant ones.

2006-06-08Ensure that cat works with any of the options, -A -v -e -E -T,Jim Meyering
when applied to files in /proc and /sys, even when the FIONREAD ioctl produces nonsensical results. Before this change, cat would produce no output (or truncated output), for some linux kernels. * src/cat.c (write_pending): New function, factored out of cat. (cat): Also interpret a negative ioctl/FIONREAD count as indicating that there are bytes to read. Some versions of linux-2.6.16 do that. Write any pending output before returning. Reported by Dan Jacobson in <http://bugs.debian.org/370583>. * NEWS: Mention this bug fix. * tests/misc/cat-proc: New file. Test for the above. * tests/misc/Makefile.am (TESTS): Add cat-proc.

2005-12-14(main): Check for close (STDOUT_FILENO) failure.Paul Eggert
2005-07-11(usage, main, long_options) [O_BINARY]:Paul Eggert
Remove support for -B. Use same rules as other programs to decide whether to use binary I/O, except that the -bensAE options always select text mode. (main): Avoid setmode; use POSIX-specified routines instead.

2005-07-08Include stropt.h if available.Paul Eggert

2004-07-29(exit_status): Remove. Now done by passing a booleanPaul Eggert
'ok' flag around. (simple_cat, cat): Return true if successful. All callers changed. (simple_cat, cat, main): Use bool for booleans. (simple_cat): Use size_t for sizes. (cat, main): Use the same names for parameters that we use for long options, to avoid confusion. This inverts the sense of the show_tabs (formerly output_tabs) and number_nonblank (formerly numbers_at_empty_lines) variables. (main): Don't mess up (due to integer overflow) if we are given INT_MAX - INT_MIN + 1 options. [O_BINARY]: Don't invoke isatty unless the other options require it. (main): When deciding whether to use simple_cat, don't worry about binary option; it's irrelevant.
