2009-04-09id: fix infinite loop on some systemsPádraig Brady
Steven Parkes reported that `id -G $USER` went into an infinite loop on Darwin systems for users in more than 10 groups: http://bugs.gentoo.org/show_bug.cgi?id=264007 * gl/lib/mgetgroups.c (mgetgroups): Work around buggy getgrouplist implementations that don't update the required size correctly, by doubling the result buffer and retrying. Also return the parameter updated by getgrouplist rather than its return value, as the documentation doesn't actually state the number of groups stored is returned by getgrouplist. * tests/misc/id-groups: Add test to exercise this logic * tests/Makefile.am: Reference new test * NEWS: Mention the fix * THANKS: Update
2009-04-07shred,sort,shuf: don't use /dev/urandom by defaultPádraig Brady
Suggestion from Steven Schveighoffer at: http://savannah.gnu.org/patch/?6797 to greatly speed up the random passes done by shred. * gl/lib/randread.c: Default to using the internal pseudorandom generator, rather than reading /dev/urandom * src/shred.c (usage): remove mention of /dev/urandom * src/shuf.c (usage); ditto * src/sort.c (usage): ditto * doc/coreutils.text: Document the new behaviour for aquiring random data.

2009-04-03ls: fix alignment when month names have varying widthsPádraig Brady
Reported by Samuel Thibault and Stéphane Raimbault, as the glibc fr_FR locale has recently changed to use the official but variable width abbreviated month names. Other glibc locales also have variable widths. http://sourceware.org/ml/libc-locales/2008-q1/msg00035.html http://sourceware.org/bugzilla/show_bug.cgi?id=9859 * NEWS: Mention the fix * gl/lib/mbsalign.c: A new module to align and truncate a string in a specified number of screen cells, while handling multi-byte characters appropriately. * gl/lib/mbsalign.h: Ditto * gl/modules/mbsalign: Ditto * bootstrap.conf: Reference the new module * src/ls.c (abmon_init): New function, precompute the abbreviated months aligned left in a minimum width column <= 5 screen cells. (align_nstrftime): New function, replace the first %b in the format specification to strftime with the precomputed month string. Note using the cached month strings speeds up `ls -lU` by around 17% on glibc-2.7-2 on linux at least. Also if we implement this function using heap storage rather than automatic storage, and use snprintf instead of strcpy, ls will slow down by 2% and 1% respectively (i.e. a net gain of 14% rather than 17%). * tests/ls/abmon-align: A new test to test ls alignment for various formats and locales * 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

This change also adjusts two other %*s directives to be %*.*s instead, (for the padding on either side of "file_text") to correct a bug that could make pr print one space of padding instead of none. * NEWS (Bug fixes): Mention it. * tests/pr/o3Jml24f-lm-lo: Adjust for new expected output. * tests/pr/o3a3Sl24f-tn: Likewise. * tests/pr/o3a3Snl24f-tn: Likewise. * tests/pr/o3a3l24f-tn: Likewise. * tests/pr/o3b3Sl24f-tn: Likewise. * tests/pr/o3b3Snl24f-tn: Likewise. * tests/pr/o3b3l24f-tn: Likewise. * tests/pr/o3mSl24f-bl-tn: Likewise. * tests/pr/o3mSnl24fbltn: Likewise. * tests/pr/o3ml24f-bl-tn: Likewise.
2009-02-27cp: diagnose invalid "cp -rl dir dir" right away, once againJim Meyering
Running "mkdir dir; cp -rl dir dir" would create dir/dir/dir/... rather than diagnosing the "copy-into-self" failure. The easy fix would have been to revert this part of the change [3ece0355 2008-11-09 cp: use far less memory in some cases] that introduced the bug: - remember_copied (dst_name, dst_sb.st_ino, dst_sb.st_dev); + if (!x->hard_link) + remember_copied (dst_name, dst_sb.st_ino, dst_sb.st_dev); However, that would have induced the failure of the new cp/link-heap test, due to the added memory pressure of recording 10k dev/ino pairs. And besides, I liked that improvement and wanted to keep it. Now that it's obvious recording the just-created-directory dev/ino needn't depend on the setting of hard_link, I realized it is necessary to record the pair only for the first directory created for each source command-line argument. I made that change, then noticed the new test, cp -rl a d d, would pass when run once, yet output the into-self diagnostic twice. Also note the side effect: it creates d/a and d/d. However, running that same command a second time, now with the modified directory, would fail. That turned out to be due to the fact that although the first into-self failure was detected in copy_dir, that function would continue copying other entries regardless -- and that would make it fail (eventually) with the unwanted recursion. * src/copy.c (copy_internal): This function needed an indicator of whether, for a give command line argument, it had already created its first directory. If so, no more need to record dev/ino pairs. If this is the first, then do record its pair. Hence, the new parameter. (copy_dir, copy): Update callers. (copy_dir): Upon any into-self failure, break out of the loop. * tests/cp/into-self: Test for the above. Reported by Mikael Magnusson.
2009-02-26sort: Fix two bugs with determining the end of fieldPádraig Brady
* src/sort.c: When no specific number of chars to skip is specified for the end field, always skip the whole field. Also never include leading spaces from next field. * tests/misc/sort: Add 2 new tests for these cases. * NEWS: Mention this bug fix. * THANKS: Add bug reporter. Reported by Davide Canova.

2009-01-28dd: Better handle user specified offsets that are too bigPádraig Brady
Following are the before and after operations for seekable files, for the various erroneous offsets handled by this patch: skip beyond end of file before: immediately exit(0); after : immediately printf("cannot skip to specified offset"); exit(0); skip > max file size before: read whole file and exit(0); after : immediately printf("cannot skip: Invalid argument"); exit(1); seek > max file size before: immediately printf("truncate error: EFBIG"); exit(1); after : immediately printf("truncate error: EFBIG"); exit(1); skip > OFF_T_MAX before: read whole device/file and exit(0); after : immediately printf("cannot skip:"); exit(1); seek > OFF_T_MAX before: immediately printf("truncate error: offset too large"); exit(1); after : immediately printf("truncate error: offset too large"); exit(1); skip > device size before: read whole device and exit(0); after : immediately printf("cannot skip: Invalid argument"); exit(1); seek > device size before: read whole device and printf("write error: ENOSPC"); exit(1); after : immediately printf("cannot seek: Invalid argument"); exit(1); * NEWS: Summarize this change in behavior. * src/dd.c (skip): Add error checking for large seek/skip offsets on seekable files, rather than deferring to using read() to advance offset. (dd_copy): Print a warning if skip past EOF, as per FIXME comment. * test/Makefile.am: Add 2 new tests. * tests/dd/seek-skip-past-file: Add tests for first 3 cases above. * tests/dd/seek-skip-past-dev: Add root only test for last case above.

2008-12-02wc: read and process --files0-from= input a name at a time,Jim Meyering
when the file name list is not too large. Before, wc would always read the entire file name list into memory and *then* process each file name. wc does read the list into memory when the list is known not to be too large; this is done in order to be able to align the output numbers, as it does with arguments specified on the command-line * src/wc.c: Include "argv-iter.h". (main): Rewrite to use argv-iter when the input file name list is known to be too large. * NEWS (Bug fixes): Mention it.
2008-12-02du: read and process --files0-from= input a name at a time,Jim Meyering
rather than by reading the entire input into memory and *then* processing each file name. * src/du.c: Include "argv-iter.h", not "readtokens0.h". (main): Rewrite to use argv-iter. Call xfts_open on each argument, rather than on the entire argv list at once. Call print_size here, not from du_files. Diagnose read failure. * NEWS (Bug fixes): Mention it. * THANKS: update.

2008-11-20cp: use far less memory in some casesJim Meyering
cp --link was "remembering" many name,dev,inode triples unnecessarily. cp was doing the same, even without --link, for every directory in the source hierarchy, while it can do its job with entries merely for the command-line arguments. Prompted by a report from Patrick Shoenfeld. Details <http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/15081>. * src/copy.c (copy_internal): Refrain from remembering name,dev,inode for most files, when invoked via cp --link. Record an infloop-avoidance triple for each directory specified on the command line, not for each directory in the source tree. Don't record a dir-triple when x->hard_link is set. * NEWS (Buf fixes): Mention it. * tests/cp/link-heap: New file. Test for cp's lowered memory usage. * tests/Makefile.am (TESTS): Add link-heap.

Explain the new arbitrary-precision functionality. * NEWS: Indicate that arbitrary-precision arithmetic is now supported in expr. * src/expr.c (enum valtype): Added mp_integer, signifying a GNU MP number. (usage): Document the new options --bignum and --no-bignum which force and prohibit the use of arbitrary-precision arithmetic, respectively. (long_options): data structure for getopt_long, which we need to use to parse the options mentioned above. (main): parse these options with getopt_long instead of parse_long_options. (valinfo): Downgrade the numeric member of the union from intmax_t to signed long, since MP lacks functions for promoting an intmax_t to an arbitrary-precision quantity. (enum arithmetic_mode): Represents the current choice between --bignum, --no-bignum and the default (automatically switch from one to the other if needed). (integer_overflow): issue a more explicit error message indicating that MP is not available. (string_too_long): new function, emits a fatal error message for the case where an argument to the 'index' expression is too long for a string offset to be represented. (int_value): With --bignum, create the value as mp_integer rather than plain integer. (substr_value): factored out of eval6; implements "substr". (freev): also destroy mp_integer values. Check that no mp_integer values exist if --no-bignum was specified. (printv, null, tostring): support mp_integer. (toint): new funtion for converting from string or mp_integer to integer. (getsize): extracts a size_t value from a VALUE object; used to implement substr. (promote): promotes a value from integer to mp_integer. (domult, dodivide): functions for multiplication and division, factored out of eval4. (doadd): addition/subraction function, factpred out of eval3. (eval3): support mp_integer types; call doadd. (eval4): support mp_integer types; call domult, dodivide. (eval6): support mp_integer offsets and lengths for "substr" and "index". * TODO: Mention that expr supports arbitrary-precision arithmetic, and suggest that this might also be a good idea for seq. * AUTHORS (expr): Add James Youngman.

(print_color_indicator): Colorize file with capability. * m4/jm-macro.m4: New configure option: --disable-libcap. Check for libcap usability. * src/Makefile.am (dir_LDADD, ls_LDADD, ...): Append $(LIB_CAP). * src/dircolors.c: Update color lists. * src/dircolors.hin: Mention new CAPABILITY color attribute. * tests/ls/capability: Test for ls - colorize file with capability. * tests/Makefile.am (root_tests): Add ls/capability. * NEWS: Mention the change.
2008-08-01factor arbitrarily large numbersJames Youngman
* m4/gmp.m4: New file; adds cu_GMP, which detects GNU MP. * configure.ac: Use cu_GMP. * src/Makefile.am: Link factor against libgmp if available. * src/factor.c: Use GNU MP if it is available. (emit_factor, emit_ul_factor, factor_using_division, factor_using_pollard_rho, extract_factors_multi, sort_and_print_factors, free_factors): new functions for the arbitrary-precision implementation, taken from an example in GNU MP. (factor_wheel): Renamed; was called factor. (print_factors_single): Renamed; was called print_factors. (print_factors): New function, chooses between the single- and arbitrary-precision algorithms according to availability of GNU MP and the length of the number to be factored. (usage, main): New options --bignum and --no-bignum. * coreutils.texi (factor invocation): Document new command-line options for the MP implementation and update the performance numbers to take into account the asymptotically faster algorithm. * TODO: Remove item about factoring large primes (it's done). * m4/gmp.m4: Add support for --without-gmp. * NEWS: Mention the new feature.
