1 GNU findutils NEWS - User visible changes. -*- outline -*- (allout)
2 * Major changes in release 4.3.0-CVS
4 ** Documentation Changes
6 The manual now includes a "Worked Examples" section which talks about
7 the various ways in which findutils can be used to perform common
8 tasks, and why some of these alternatives are better than others.
10 The -I option of xargs (which is required by the POSIX standard) is
15 *** Functional changes in locate
17 The "--regex" option of locate now assumes the regular expression to
18 be in the same syntax as is used in GNU Emacs, though this can be
19 changed with the new option --regextype. This is a change from the
20 existing behaviour (which was to use POSIX Basic Regular Expressions).
21 Since this featrue is releatively new anyway, I though it was more
22 useful to have compatibility between regular expression handling in
23 find and locate than to maintain the short-lived previous behaviour of
26 The locate program now also supports a "--regextype" long option which
27 controls which regular expression syntax is understood by locate.
28 This is a long option and has no single-letter 'short option'
31 *** Functional changes in find
33 The regular expression syntax understood by "find" can be changed with
34 the -regextype option; this option is positional, meaning that you can
35 have several tests, each using a diftinct syntax (this is not
36 recommended practice however).
42 The -iregex test now works once again on systems that lack
43 re_search() (that is, systems on which findutils needs to use the
44 gnulib version of this function).
46 find -regex now once again uses GNU Emacs-compatible regular
49 If invoked with stderr closed, the -fprint and -fprintf actions now no
50 longer cause error messages to be sent into the output file.
52 * Major changes in release 4.2.23
54 ** Documentation Changes
56 The -L and -I options of xargs are currently incompatible (but should
59 Improved the documentation for -execdir and -okdir.
61 ** Functional Changes to updatedb
63 File names ending in "/" which are specified as an argument to
64 --prunepaths (or in $PRUNEPATHS) don't work, so we now issue an error
65 message if the user tries to do that. The obvious exception of course
66 is "/" which does work and is not rejected.
69 * Major changes in release 4.2.22
73 If a directory entry searched with "find -L" is a symbolic link to
74 ".", we no longer loop indefinitely. This problem affected find
75 versions 4.2.19, 4.2.20 and 4.2.21. This problem allows users to make
76 "find" loop indefinitely. This is in effect a denial of service and
77 could be used to prevent updates to the locate database or to defeat
78 file security checks based on find. However, it should be noted that
79 you should not use "find -L" in security-sensitive scenarios.
85 ** Functional Changes to locate
87 A locate database can now be supplied on stdin, using '-' as a element
88 of the database-path. If more than one database-path element is '-',
89 later instances are ignored.
91 A new option to locate, '--all' ('-A') causes matches to be limited to
92 entries which match all given patterns, not entries which match
95 ** Documentation Changes
97 Some typos in the manual pages have been fixed. Various parts of the
98 manual now point out that it is good practice to quote the argument of
99 "-name". The manpage now has a "NON-BUGS" section which explains some
100 symptoms that look like bugs but aren't. The explanations of the "%k"
101 and "%b" directives to "find -printf" have been imrpoved.
104 * Major changes in release 4.2.21
105 ** Functional Changes to find
107 The GNU extension "find ... -perm +MODE" has been withdrawn because it
108 is incompatible with POSIX in obscure cases like "find ... -perm ++r".
109 Use the new syntax "find ... -perm /MODE" instead. Old usages will
110 still continue to work, so long as they don't conflict with POSIX.
112 If the output is going to a terminal, the -print, -fprint, -printf and
113 -fprintf actions now quote "unusual" characters to prevent unwanted
114 effects on the terminal. See "Unusual Characters in File Names" for
115 further details. There is no change to the behaviour when the output
116 is not going to a terminal. The locate program does the same thing,
117 unless the -0 option is in effect (in which case the filenames are
120 ** Functional Changes to locate
122 The locate command will now read each locate database at most once.
123 This means that if you are using multiple databases and are searching
124 for more than one name, the results will now be printed in a different
125 order (and if you specified a small limit with --limit, you may get a
126 different set of results).
128 A new option '--print' for locate causes it to print the matching
129 results even if the '--count' or '--statistics' option is in effect.
132 find /blah/blah/blah -depth -empty now works once again.
134 The -regex and -iregex tests of find now correctly accept POSIX Basic
135 Regular Expressions. (Savannah bug #12999)
137 The updatedb program now works on systems where "su" does not support
138 the "-s" option, for example Solaris.
140 * Major changes in release 4.2.20
141 ** Internationalization and Localization
142 Updated Vietnamese and Dutch translations.
145 Minor bugfix affecting only those who compile from the CVS repository,
146 as opposed to those who compile from the source releases.
148 * Major changes in release 4.2.19
151 find should now no longer hang on systems which lack the O_NOFOLLOW
152 flag to open(2) and which are clients of an unresponsive NFS server
153 (Savannah bug #12044).
155 We now avoid inappropriately failing for "find -L foo" or "find -H
156 foo" if foo is a symbolic link (Savannah bug #12181). Previously we
157 used to fail with the error message "Too many levels of symbolic
160 "find . -false -exec foo {} +" no longer runs an extra instance of foo
161 when find exits (Savannah bug #12230).
163 If the chdir() safety check fails but we can no longer get back to
164 where we started, exit with an explanatory (fatal) error message.
165 This does not happen on GNU/Linux and FreeBSD because the safety check
166 is not needed (the security problem the safety check protects against
167 is prevented in a cleaner way on those systems).
169 "make distclean" no longer deletes regex.c (which "make all" needs).
171 ** Functionality Changes
172 "find -printf "%h\n" will now print "." for files in the current directory.
173 Previously it printed nothing (but there was a bug in the %h
174 implementation anyway). This fixes Savannah bug #12085.
176 Should now build (again) on non-C99-compliant systems.
178 ** Documentation enhancements
179 Fixed some typos and clarified wording in "Working with automounters".
181 ** Internationalization and Localization
182 New Vietnamese message translation.
184 * Major changes in release 4.2.18
186 *** "find -depth" was missing out non-leaf directories when they contain
187 non-directories. This affected findutils releases 4.2.15,
188 4.2.16 and 4.2.17, but the bug is now fixed.
189 *** Find no longer hangs on systems which are clients of unresponsive
191 ** Documentation improvements
192 *** Improvements and corrections to the find.1 manpage, including corrections to the descriptions of -H and -L.
194 * Major changes in release 4.2.17
196 *** bug #11861 undefined symbol "basename" on IRIX 5.3
197 *** bug #11865 xargs -i regression (as compared to findutils-4.2.12)
198 *** bug #11866 Typo in pred_okdir renders it useless (affecting 4.2.16 only)
199 *** patch #3723 fix recent process_top_path change (for -execdir on /)
200 *** Fixing bug #11866 and applying patch #3723 made -execdir work much better.
201 *** find bar/baz/ugh now works again if baz is a symbolic link (broken
204 * Major changes in release 4.2.16
205 ** Functionality Changes
206 *** Updated the message catalogues for the translated messages.
207 *** The subfs filesystem is now treated the same as the autofs
209 *** New translations: Belarusian, Catalan, Greek, Esperanto,
210 Finnish, Irish, Croatian, Hungarian, Japanese, Luganda,
211 Malay, Romanian, Slovenian, Serbian, Chinese (simplified).
214 *** The -execdir action now works correctly for files named on the
217 * Major changes in release 4.2.15
218 ** Functionality Changes
219 *** locate now supports matching regular expression (--regex).
220 *** --enable-d_type-optimization (introduced in findutils 4.2.13) is now turned on by default.
222 * Major changes in release 4.2.14
223 ** Functionality Changes
224 *** New options -L, -P, -H for locate. The work in the same was as the same options for find.
226 *** Don't include the "findutils/find/testsuite/find.gnu" subdirectory in the
227 distributed tar file more than once.
228 *** Should now build on Solaris once again.
229 *** -xtype and -printf %Y now work correctly for symbolic links once again
230 ** Documentation improvements
231 *** All options for "locate" are now documented
233 * Major changes in release 4.2.13
234 ** Performance Enhancements
235 *** On Linux and some other systems, a large performance improvement,
236 because we can eliminate many of the calls to lstat() (in extreme
237 cases, 99% of them). Limited testing shows a 2x speedup on NFS
238 filesystems. Other systems which can make use of this enhancement
239 include Mac OS X and *BSD.
241 * Major changes in release 4.2.12
242 ** Functionality Changes
243 *** find is now POSIX-compliant, as far as I know.
244 *** -exec ... {} + now works.
245 *** New actions -execdir and -okdir which are like -exec and -ok but more secure.
246 *** "locate -w" is now a synonym for "locate --wholepath".
247 *** An empty path entry in the locate database path (for example "::" in
248 $LOCATE_PATH or in the argument to "locate -d") is taken to mean
249 the default database, whose name is hard-coded in locate.
251 *** If find or xargs cannot write to stdout, for example because
252 output is redirected to a file and the disk is full, the
253 relevant program will return a non-zero exit status.
255 * Major changes in release 4.2.11
257 *** Compilation fix for systems without EOVERFLOW.
258 *** More helpful error message if you make a mistake with (, ), -o or -a.
259 ** Functionality Changes
260 *** If you have unclosed parentheses on the find command line,
261 or any of a number of similar problems, find will now produce
262 a more helpful error message.
263 *** locate -b is now a synonym for locate --basename
264 *** locate now supports a --statistics (or -S) option, which prints some
265 statistics about the locate databases.
266 *** Implemented the -samefile option.
267 ** Documentation improvements
268 *** New chapter in the manual, "Security Considerations".
269 *** Better documentation for -prune (Mainly thanks to Stepan Kasal)
271 *** locate's options -i and -w now work with the -e option (previously a bug
274 * Major changes in release 4.2.10
276 *** Portability fix for fstype.c: should now compile on UNICOS, and possibly
277 also produce useful results on BeOS and Dolphin, perhaps other
280 * Major changes in release 4.2.9
281 ** Functionality Changes
282 *** xargs no longer treats a line containing only an underscore as a logical end-of-file. To obtain the behaviour that was previously the default, use "-E_".
283 *** xargs now supports the POSIX options -E, -I and -L. These are synonyms
284 for the existing options -e, -i and -l, but the latter three are
287 *** xargs -n NUM now invokes a command as soon as it has NUM arguments.
288 Previously, it waited until NUM+1 items had been read, and then
289 invoked the command with NUM arguments, saving the remaining one
291 *** If "find -L" discovers a symbolic link loop, an error message is issued.
292 *** If you specify a directory on the find command line, but -prune
293 is applied to it, find will no longer chdir() into it anyway.
294 ** Documentation improvements
295 *** The precise interpretation of the arguments to the -atime, -ctime
296 and similar tests in find has been documented more clearly.
298 * Major changes in release 4.2.8
299 *** Bugfix to the findutils 4.2.7 automount handling on Solaris. This
300 worked to some extent in findutils-4.2.7, but is much improved in
303 * Major changes in release 4.2.7
304 ** Functionality Changes
305 *** xargs can now read a list of arguments from a named file, allowing
306 the invoked program to use the same stdin as xargs started with
307 (for example ``xargs --arg-file=todo emacs'').
308 ** Documentation improvements
309 *** The Texinfo manual now has an extra chapter, "Error Messages". Most
310 error messages are self-explanatory, but some of the ones which
311 are not are explained in this chapter.
313 *** Avoid trying to link against -lsun on UNICOS, which doesn't need it or
315 *** Bugfix to the findutils 4.2.6 automount handling (which hadn't been enabled
317 *** Reenabled internationalisation support (which had been accidentally
318 disabled in findutils-4.2.5).
320 * Major changes in release 4.2.6
322 *** find now copes rather better when a directory appears to change just as
323 it is about to start examining it, which happens with automount.
324 This is because automount mounts filesystems as you change
325 directory into them. This should resolve Savannah bugs #3998,
328 * Major changes in release 4.2.5
329 ** Functionality Changes
330 *** The POSIX options -H and -L are supported. These control whether or not
331 find will follow symbolic links.
332 *** The BSD option -P is also now supported (though in any case
334 ** Documentation improvements
335 *** Better documentation for "xargs -i".
337 *** "make install" now respects DESTDIR when generating localstatedir.
338 (this is only relevant if you are installing to some location
339 other than the one that you indictaed when you ran "configure").
340 *** Compatible with automake versions 1.8 and 1.9.
341 *** Build problems on UNICOS now fixed, though the linker will still generate
342 warnings because we try to link with the nonexistent library
343 "-lsun". Edit $(LIBS) to work around this problem.
345 * Major changes in release 4.2.4
346 ** Functionality Changes
347 *** If your system sort command has a working "-z" option, updatedb will
348 now correctly handle newline characters in filenames (as will
350 *** xargs now uses 128Kb of command line by default (less if the system
351 doesn't support that much).
352 *** If you specify a 'find' option after non-option, a warning message
353 is now issued. Options should be specified immediately after the
354 list of paths to search. These warnings are enabled if you
355 specify the -warn option, or if stdin is a tty. They are diabled
356 by the use of the -nowarn option.
357 *** Like find, the locate program now supports an option --null (short form -0)
358 which changes the result separator from newline to NULL.
359 *** Locate supports the option -c (long form --count) which suppresses normal
360 output but prints on stdout the number of results produced (like
362 *** Locate supports the option -l (long form --limit) which limits the
363 number of results. This is useful if you only want to find out if
364 there are copies of a certain file on the system, but don't want
365 to wait for the entire locate database to be searched.
366 *** Locate now has an option --basename which forces the specified pattern to
367 be matched against the basename of the entries in the locate
368 database, rather than the whole name. The default behaviour
369 (matching against the whole name of the file including all the
370 parent directory names) corresponds to the option --wholename.
371 *** updatedb has a new option, --findoptions, that can be used to
372 pass extra options through to the find command that it uses.
374 *** "find -printf '%H\n'" now works (rather than segfaulting) on
375 systems that have non-writable string constants.
376 *** Better POSIX compliance for the -s option to xargs (out of range
377 values should just result in bounding to the correct range, not an
378 error, so now we just print a warning message and adjust the
380 *** Corrected section numbers of manual page cross-references
382 * Major changes in release 4.2.3
383 ** Functionality Changes
384 *** Added new action -delete which deletes things that find matches.
385 *** Added new action -quit which causes find to exit immediately.
386 *** A new format directive '%D' for "find -printf" prints the device number.
387 *** The -ls predicate no longer truncates user or group names.
388 *** Added new option "-d" which is a synonym for "-depth" for compatibility
389 with Mac OS, OpenBSD and FreeBSD. This option is already
390 deprecated since the POSIX standard specifies "-depth".
391 *** Added two new format specifiers to the -printf action; these are
392 %y and %Y. They indicate the type of the file as a single letter;
393 these are the same latters as are used by the "-type" test.
394 *** If a parent directory changes during the execution of find,
395 the error message we issue identifies the nature of the change
396 (for example the previous and current inode numbers of the
397 directory we've just returned out of).
399 *** Non-functional code changes to silence compiler warnings.
401 * Major changes in release 4.2.2
402 ** Documentation improvements
403 *** "find ... -exec {}+" is not yet supported.
405 *** Fixed compilation problems on Solaris, RedHat EL AS 2.1, Irix, AIX
406 *** Work around possible compiler bug on HP-UX 11.23 for ia64
407 *** The built-in internationalisation support now works again.
409 *** We now import the gnulib source in the way it is intended to be used,
410 which means among other things that we only have one config.h file
412 *** Functions which findutils requires but which are not present in
413 gnulib are now defined in "libfind.a". This is in the lib
414 directory, while gnulib is in the gnulib subdirectory.
415 *** Fixed a typo in the address of the FSF in many of the file headers.
417 * Major changes in release 4.2.1
419 *** 'find -name \*bar now matches .foobar, because the POSIX standard
420 requires it, as explained at
421 http://standards.ieee.org/reading/ieee/interp/1003-2-92_int/pasc-1003.2-126.html
423 * Major changes in release 4.2.1
425 *** find -iname now works correctly on systems that have an fnmatch() function
426 that does not support FNM_CASEFOLD
427 *** updatedb now uses signal names for "trap" instead of numbers,
428 as per bug #9465 (see http://www.opengroup.org/onlinepubs/009695399/utilities/trap.html)
429 *** Better support for systems lacking intmax_t
431 **** findutils now uses a newer version of gnulib (dated 2004-10-17).
433 * Major changes in release 4.2.0
434 ** Functionality Changes
435 *** xargs now works better when the environment variables are very extensive.
436 The xargs command used to run into difficulties if the environment
437 data contained more than 20480 bytes.
438 *** New options -wholename and -iwholename
439 As per the GNU Projecvt coding standard, These are preferred over
440 the -path and -ipath options. Using -ipath now generates a warning,
441 though -path does not (since HPUX also offers -path).
442 *** The environment variable FIND_BLOCK_SIZE is now ignored.
443 *** New option "-ignore_readdir_race"
444 silences an error messages which would otherwise occur if a file is removed
445 after find has read it from the directory using readdir(), but before
446 find stats the file. There is also an option
447 -noignore_readdir_race which has the opposite effect.
448 ** Documentation improvements
449 *** The -size option of find is now documented in more detail
450 *** POSIX compliance and GNU extensions
451 The find manual page also now includes a section
452 which describes the relationship between the features of GNU
453 find and the POSIX standard. Some other small improvements
454 to the find and xargs manual pages have been made.
455 *** The argument to the -fprintf directive is now better documented.
456 The escape code '\0' for the `-printf' predicate of find is now
457 documented, and the documentation for the %k and %b specifiers
459 *** xargs -i is now more clearly documented.
461 *** locate 'pa*d' will now find /etc/passwd (if it exists, of course)
462 *** xargs standard input is not inherited by child processes
463 If the command invoked by xargs reads from its standard input,
464 it now gets nothing, as opposed to stealing data from the
465 list of files that xargs is trying to read.
466 *** Better support for 64-bit systems.
467 *** The command "xargs -i -n1" now works as one might expect,
468 I think this is a strange thing to want to do.
469 *** Arguments to find -mtime that are too large are now diagnosed
470 Previously, this just used to cause find just to do the wrong thing.
471 *** updatedb is now somewhat more robust
472 The updatedb shell script now does not generate an empty
473 database if it fails.
474 *** Sanity-check on some data read from locatedb
475 Locate now detects some types of file corruption in the
477 *** The %k format specifier for -fprintf now works
478 This was broken in 4.1.20.
480 * Major changes in release 4.1.20:
481 ** New maintainer, James Youngman <jay@gnu.org>
482 ** As far as I know, this is the first release after 4.1.7, but I've left
484 ** We now use an "imported" version of gnulib, rather than including
485 a copy of the gnulib code in our CVS repository. There are no
486 differences in the build instructions, though (unless you are
487 building directly from CVS, in which case please read the file
489 ** There are no (deliberate) functional changes in version 4.1.20.
491 * Major changes in release 4.1.7:
492 fix problem so that default "-print" is added when "-prune" is used.
493 security fixes related to directories changing while find is executing.
495 * Major changes in release 4.1.6:
496 correct bug in prune.
497 added --ignore-case option for locate
499 * Major changes in release 4.1.5:
500 Add support for large files
502 * Major changes in release 4.1.4:
503 bug fixes, more up-to-date languages.
505 * Major changes in release 4.1.3:
506 added internationalization and localization.
508 * Major changes in release 4.1.1:
509 attempt at successful compilation on many platforms after years of neglect
510 "--existing" option added to locate "--prunefs" option added to updatedb
512 * Major changes in release 4.1:
514 ** Distribution renamed to findutils.
515 ** updatedb is now a user command, installed in $exec_prefix/bin
516 instead of $exec_prefix/libexec.
517 ** A few problems in Makefiles and testsuite corrected.
519 * Major changes in release 4.0:
523 *** Man page for updatedb.
524 *** Man page for the locate database formats.
527 *** Takes less CPU time on long paths, because it uses chdir to descend
528 trees, so it does fewer inode lookups.
529 *** Does not get trapped in symbolic link loops when -follow is given.
530 *** Supports "-fstype afs" if you have /afs and /usr/afsws/include
531 and you configure using the --with-afs option.
532 *** New action -fls FILE; like -ls but writes to FILE.
535 *** Supports a new database format, which is 8-bit clean and
536 allows machines with different byte orderings and integer sizes to
537 share the databases. The new locate can also detect and read the
538 old database format automatically. The new databases are typically
539 30% or more larger than the old ones (due to allowing all 8 bits in
540 file names). Search times are approximately the same, or faster on
542 *** Warns if a file name database is more than 8 days old.
545 *** Takes command-line options.
548 *** Performance improved 10-20%.
549 *** The EOF string is not used when -0 is given.
550 *** Now has a test suite. Some minor bugs fixed as a result.
552 * Major changes in release 3.8:
554 ** case insensitive versions of -lname, -name, -path, -regex:
555 -ilname, -iname, -ipath, -iregex
556 ** %F directive for -printf, -fprintf to print file system type
558 * Major changes in release 3.7:
560 ** locate can search multiple databases
561 ** locate has an option to specify the database path
562 ** updatedb no longer goes into an infinite loop with some versions of tail
