source: trunk/third/findutils/TODO @ 18890

-*-outline-*-
* lib/filemode.c has "# undef S_ISDOOR" added.  This should be moved upstream.

* -fstype core dumps on sparc-sun-sunos4.1.3_U1 with gcc-2.95.2
This is on foxtrot.rahul.net.  dbx does not work on compiled find.
Perhaps gcc is installed incorrectly.  "find / -fstype ufs" core dumps
quickly.  cc works correctly.

* Speed of locate without "-i" option needs to be increased.

* There are many bugs to be fixed and features to be added to findutils.
The current distribution is a snapshot which fixes many
problems, but leaves others unsolved.  Many of the known problems are
not listed below.  Over the next few releases, I hope to fix more
items, and add the unfixed problems below.

* Internationalization
** Is ansi2knr internationalized?  Does it need to be?

** Should these files be internationalized?
        strftime.c

** Should translated long options be offered in locate and xargs?
** updatedb.sh should be internationalized as well

* new standards with Austin group
** "-H" and "-L" options to find were added by Austin group standards.
They need to be implemented.

**Austin added the following options to xargs:
-I perhaps replaces -i

-L perhaps replaces -l

-E slightly different from -e

* Should fnmatch.h be a link to fnmatch.h.in?
See tar distribution for an example. 

* Eliminate unnecessary strcpy calls in xargs.

* lib/getline.c
getline.c contains a function getstr which is needed in locate,
but is not in the standard library.  In fact getstr is in curses.
This problem needs to be fixed.  Can getstr be removed?  Can getline.c
be optionally included, or is it mandatory?

* man pages for frcode, bigram, and code
Perhaps a better description in texi pages as well.

* Add option for find to sort output in lexical order for use for updatedb
olarsac@airfrance.fr (Olivier) made the following suggestion:

As I was running thru the code looking for the bug I wondered why the updatedb
has to use sort...
why not add an option to find that sorts the output in lexical order?
my point is:
- sort on a big list is costly (here we do locate on big big file system)
- find may (in theory) sort incrementally very easily by sorting only the current
directory entries before recursion
- it would also solve the lack of \0 sort that prevents you to use the -print0
to handle \n in file names properly


* large file problems
depcomp gets added by automake
strncasecmp is needed
which requires strcasecmp
getline.c temporarily removed from Makefile.am
remove getline.o from LIBOBJS
remove extra AM_FUNC_GETLINE

* Is lib/strcasecmp.c required?

* xargs: allow newline or arbitrary character to separate arguments
Tyler 'Crackerjack' MacDonald <yi@yi.org> suggested that it would be
nice if newlines could separate arguments to xargs.  This would allow
a single line to be used as an argument, regardless of white space,
quotes, and backslash.  A function similar to read_string in xargs.c
can be written which replaces the line:

      if (c == '\0')

with the appropriate character.

* investigate _LIBC when used with TOLOWER and TOUPPER
_LIBC is used to determine whether TOLOWER should check isupper first.
Is there something better to check?  Alternatively, can tolower be
checked at run time to determine whether isupper should be called first.

* make findutils multibyte safe
Bruno Haible reported many problems with findutils and multibyte.

* BeOS problems with multibyte
Bruno Haible reported problems with BeOS.

* What should be the default value of PRUNEFS in updatedb?
Currently, it is:
: ${PRUNEFS="nfs NFS proc"}
Perhaps it should default to nothing.

* Include example of use of updatedb in documentation.
Use something close to the Debian daily cron job.

* Side effects do not allow the implicit use of -print.
Specifically, the use of -prune turns off the implicit use of -print.
Look at this line in find.c:
  else if (!no_side_effects (predicates->pred_next))
side_effects really means:
predicate which produces output, according to find.c, at least it does
some of the time.
Two predicates, side_effects, and produce_output


* Supply example for time range commands for find.
