2011-01-29join: don't report disorder against an empty filePádraig Brady
This allows one to use join as a field extractor like: join -a1 -o 1.3,1.1 - /dev/null * src/join.c (join): Don't flag unpairable lines when one of the files is empty. * tests/misc/join: Add a new test for empty input, and adjust a previous test that was only checking against empty input. * doc/coreutils.texi (join invocation): Document the change. * NEWS: Likewise.
2011-01-29join: ensure --header skips the order check with empty filesPádraig Brady
* src/join.c: Skip the header even if one of the files is empty. * tests/misc/join: Add a test case. * NEWS: Mention the fix
2011-01-29join: add -o 'auto' to output a constant number of fields per linePádraig Brady
Lines with a different number of fields than the first line, will be truncated or padded. * src/join.c (prfields): A new function refactored from prjoin(), to output all but the join field. (prjoin): Don't swap line1 and line2 when line1 is blank so that the padding is applied to the right place. (main): Handle the -o 'auto' option. * tests/misc/join: Add 6 new cases to test the auto format. * NEWS: Mention the change in behavior. Suggestion from Assaf Gordon
2011-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
2010-09-01join: improve performance when operating on whole linesPádraig Brady
Following on from commit f86bb696, 01-02-2010, "join: make -t '' operate on the whole line". Bypassing the delimiter search in this case, gives about an 8% performance boost. * src/join (xfields): Don't bother looking for '\n' in the data, which we know won't be present.
2010-07-22provide POSIX_FADV_SEQUENTIAL hint to appropriate utilsPádraig Brady
Following on from commit dae35bac, 01-03-2010, "sort: inform the system about our input access pattern" apply the same hint to all appropriate utils. This currently gives around a 5% speedup for reading large files from fast flash devices on GNU/Linux. * src/base64.c: Call fadvise (..., FADVISE_SEQUENTIAL); * src/cat.c: Likewise. * src/cksum.c: Likewise. * src/comm.c: Likewise. * src/cut.c: Likewise. * src/expand.c: Likewise. * src/fmt.c: Likewise. * src/fold.c: Likewise. * src/join.c: Likewise. * src/md5sum.c: Likewise. * src/nl.c: Likewise. * src/paste.c: Likewise. * src/pr.c: Likewise. * src/ptx.c: Likewise. * src/shuf.c: Likewise. * src/sum.c: Likewise. * src/tee.c: Likewise. * src/tr.c: Likewise. * src/tsort.c: Likewise. * src/unexpand.c: Likewise. * src/uniq.c: Likewise. * src/wc.c: Likewise, unless we don't actually read().

2010-02-11doc: remove extraneous periods from --help outputPádraig Brady
* src/join.c (usage): Mention "fields" rather than repeating "line" so that it's more obvious that the fields are still parsed, and thus -o is still honored for headers. Also remove an extraneous '.' reported by Stéphane Raimbault. * src/base64.c (usage): Remove extraneous blank line and order the options alphabetically. Also remove an extraneous '.' * src/chown.c (usage): Remove extraneous '.' * src/cp.c (usage): Likewise. * src/mktemp.c (usage): Likewise. * src/pr.c (usage): Likewise. * src/stat.c (usage): Likewise. * src/uniq.c (usage): Likewise.
2010-02-01join: make -t '' operate on the whole linePádraig Brady
Previously passing an empty parameter to -t would raise an error, but now it means to treat each line as a single field for matching. This matches the default operation of `sort` which is usually used in conjunction with join. * src/join.c (main): Set the field delimiter to '\n' if an empty parameter is passed to -t. (usage): Mention the operation of -t ''. * tests/misc/join: Add 2 new tests, for the existing -t '\0' and the new -t '' functionality. * doc/coreutils.texi (join invocation): Mention that join -t '' always operates on the whole line, while join -t '\0' usually does. * NEWS: Mention the change in behavior.
2010-02-01join: add --header option to always output the first lineAssaf Gordon
This essentially allows one to use --check-order with headings. Note join without --check-order will already handle the common case where headings do match in each file, however using --check-order will fail often when the header sorts after the first line of data. Note also that this will join header lines from each file even if they don't match, with headings from the first file being used. * NEWS: Mention the new option. * doc/coreutils.texi (join invocation): Describe the new option. * src/join.c (usage): Likewise. (join): Join the header lines unconditionally. * tests/misc/join: Add 5 new tests.
2010-02-01maint: fix an inconsequential memory leak in joinPádraig Brady
* src/join.c (join): Refactor the code that checks for misorder at the tail of the files. The most significant change here is that freeline() is called thus silencing a valgrind warning about a definite but inconsequential memory leak. (freeline): Make more general by doing nothing when passed NULL, and setting freed pointers to NULL.
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
2009-09-21doc: 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

2009-05-05doc: note the use of LC_COLLATE in comm, join and uniqPádraig Brady
* doc/coreutils.texi (uniq invocation): Simplify the text to remove the inconsequential mentioning of order, while implying that LC_COLLATE can alter equality comparisons. * src/comm.c (usage): Mention LC_COLLATE is significant. * src/join.c (usage): Ditto. * src/uniq.c (usage): Ditto. Also improve the summary. Suggestion from Andries Brouwer
2008-11-10make --help print "Report PROGRAM translation bugs to <...>."Jim Meyering
for all but the C/POSIX locale. * src/system.h: Include "hard-locale.h". (emit_bug_reporting_address): Tell where to report translation bugs. don't include "hard-locale.h", now that system.h does * src/comm.c: Likewise. * src/join.c: Likewise. * src/ls.c: Likewise. * src/pinky.c: Likewise. * src/pr.c: Likewise. * src/sort.c: Likewise. * src/uniq.c: Likewise. * src/who.c: Likewise.
2008-06-17join: improve memory managementBo Borgerson
* src/join.c (struct seq): Use a (struct line **) for `lines' rather than one long (struct line *). This allows individual lines to be swapped out if necessary. (reset_line): Get a line ready for new input. (init_linep): Create a new line and assign it to the the pointer passed in. (spareline[2]): Hold a spare line for each input file. (free_spareline): Clean up. (get_line): Take a (struct line **) instead of a (struct line *). If the line to be overwritten is the previous line for the current file then swap it out for the spare. (join): Accomodate new structure of SEQs and new parameters to get_line; Don't free stale lines until the end -- they're re-usable now. (dup_line): Remove function. * NEWS: Mention the performance improvement.
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.

2008-03-25join bug fix: adapt keycmp to work with new order-checking featureJim Meyering
* src/join.c (keycmp): Add two join-field parameters. (check_order, join): Update callers. Reported by Dmitry V. Levin in http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/12731/focus=13017 * tests/join/Test.pm (chkodr-7): New test for this fix.

* src/join.c (check_order): Rename from checkorder. Move definition to precede first use and remove prototype. Use EXIT_FAILURE, rather than "1". (key_cmp): Move definition to precede first use.
2008-02-20join: avoid new leaksJames Youngman
* src/join.c (prevline): Make prevline module-level static, so that the allocated items can be freed at exit. (free_prevline): new atexit function; frees items in prevline[]. Use ARRAY_CARDINALITY, so include "argmatch.h" to get that. (main): Arrange for free_prevline to be called during exit. (get_line): Free prevline[which - 1] also, as that will have been allocated by dup_line.
2008-02-19join: new options: --check-order and --nocheck-order.James Youngman
* src/join.c: Support --check-order and --nocheck-order. New variables check_input_order, seen_unpairable and issued_disorder_warning[]. For --check-order, verify that the input files are in sorted order. For the default case, check the order only if there are unpairable lines. (join): Perform ordering checks after reaching EOF on either input. (usage): Mention --check-order and --nocheck-order. (dupline): Save a copy of the previously-read input line so that we can detect disorder on the input. (get_line): Temporarily save a copy of the previous line (by calling dupline) and check relative ordering (by calling checkorder) before returning the newly-read line. (getseq, join): Tell get_line which file we are reading from. (advance_seq): New function, factoring out some of the code commonly surrounding calls to getseq. (checkorder): New function. Verifies that a pair of consecutive input lines are in sorted order. * doc/coreutils.texi (join invocation): Document the new options --check-order and --nocheck-order. * tests/join/Test.pm (tv): Added tests for --check-order and --nocheck-order. * NEWS: Mention this new feature.

2006-12-13Remove some arbitrary restrictions on size fields,Paul Eggert
so that commands like "sort -k 18446744073709551616" no longer fail merely because 18446744073709551616 doesn't fit in uintmax_t. The trick is that these fields can all be treated as effectively infinity; their exact values don't matter, since no internal buffer can be that long. * src/join.c (string_to_join_field): Verify that SIZE_MAX <= ULONG_MAX if the code assumes this. Silently truncate too-large values to SIZE_MAX, as the remaining code will do the right thing in this case. * src/sort.c (parse_field_count): Likewise. * src/uniq.c (size_opt, main): Likewise. * tests/join/Test.pm (bigfield): New test. * tests/sort/Test.pm (bigfield): New test. * tests/uniq/Test.pm (121): New test.

2005-04-26Remove posixver.h and its uses.Paul Eggert
(obsolete_usage): Remove. (join_field_1, join_field_2): Initialize to SIZE_MAX to indicate they haven't been set yet. (tab): Now int, not char. Initialize to -1 to indicate white space separates columns, so that we can use NUL as a separator. All uses changed. (OBSOLETE_LONG_OPTIONS, get_option): Remove. (string_to_join_field): Remove ERR_MSG_FMT arg; a single format suffices. Use xstrtoul for sizes; it suffices. (decode_field_spec): Report an error and exit on failure. Return void, not bool. (add_field_list): Likewise. (set_join_field): New function. (enum operand_status): New enum. (add_file_name): New args OPERAND_STATUS, JOPTION_COUNT, PREV_OPTC_STATUS, OPTC_STATUS to handle the bewildering array of possibilities with obsolete option parsing. (main): Use it. Do not depend on POSIX version. Check for conflicting options. Parse obsolete options -j1 and -j2 so that it is a pure extension to POSIX 1003.1-2001. Allow '-t\0' to specify a NUL tab, stealing the code from 'sort'.
2005-04-11Include stdio-safer.h.Paul Eggert
