them in the include files as well by checking for the proper
define from include/bits/uClibc_config.h (pulled in from features.h)

-General release feature sets:
--------------------------------------------------
-.29 will be mostly as-is
-.30 will be the NPTL merge
-.31 for the no-kernel-headers fix, etc, etc.

-TODO list for the uClibc 0.9.29 release:
--------------------------------------------------
- *) as many of the arch-specific issues as possible
- *) Remove N instances of libc_hidden_proto() from uClibc internals.
- Instead add internal only header(s) defining all hidden prototypes.
- This will avoid clutter and guarantee prototype consistancy.
- *) The __is*_l() functions were all removed, such that we now only export
- the is*_l() functions (no prefix). Before, we had the prefixed versions
- for use by libstdc++ and weak versions without prefixes exported because
- those functions belong to no std (unless you call glibc a std). This should
- be fixed. Similar problems likely were created elsewhere.
- *) misc stdio bugs:
- http://bugs.uclibc.org/view.php?id=420
- http://bugs.uclibc.org/view.php?id=539
- *) bug in getopt handling:
- http://bugs.uclibc.org/view.php?id=61
- http://www.uclibc.org/lists/uclibc/2006-January/013851.html
- *) Should integrate test subdir better ... need to propagate CPU
- CFLAGS/LDFLAGS to the build/link for target binaries so that when we have
- a multilib toolchain, the proper ABI is selected.

*) glob / fnmatch tests fail
*) regex should pass AT&T conformance tests
*) Finish hiding uClibc internal symbols from our exported namespace
and perhaps others (finalize list) produce a lib with a differing
ABI. Make it so apps cannot use an ABI mis-matched uClibc.
This is most easily done using symbol versioning...
- *) Implement the long double versions of math funcs
- using wrappers on top of the double versions (size / precision
+ *) Implement the long double versions of math funcs on interrested
+ arches using wrappers on top of the double versions (size / precision
trade off where size clearly wins).
*) Make all small objects (>~50 bytes) into either inlines or
into a static library
*) Cleanup/scrub all the Makefile copyright junk
*) Fix dlopen, for both static and dynamic cases, and make it
fully comply with SuSv3
- *) From the the ELF spec "...All shared object initializations happen
- before the executable file gains control. ... Before the initialization
- code for any object A is called, the initialization code for any other
- objects that object A depends on are called. For these purposes, an object
- A depends on another object B, if B appears in Ads list of needed objects
- (recorded in the DT_NEEDED entries of the dynamic structure). The order of
- initialization for circular dependencies is undefined." uClibc's shared
- lib loader should be fixed to run ctors in the specified order.
+ *) check if sched_getcpu is only pulled in where it should be
+ *) remove HANDLE_OLDER_RLIMIT, NEW_GETRLIMIT (conditionalize on
+ ugetrlimit, it seems, else use the modern variant)
+ *) simplify exec*() in the light of execvpe (perhaps single internal
+ impl); USE_GNU for execvpe (and other GNU extensions, see psm).
TODO list for AFTER the uClibc 1.0.0 release:
-------------------------------------------------
+ *) Add support for 64bit time (to deal withhttp://2038bug.com/):
+ date -s 011903142038 sets epoch to roll over in a few seconds (2^31)
*) Add support for Linux 2.6.x fast vsyscalls
*) Enable pristine source tree builds
*) Fix regex so it isn't so stinking big
*) run 'nm -D --size-sort -t d libuClibc-0.9.26.so' and work on the
biggest things (i.e. stuff at the end of the list) to make
them smaller.
+ *) Fix dlopen/dlsym/dlclose locking to more fine grained or use RCU
<more wishlist items here>
arm:
update crt1 code again for nommu (http://bugs.uclibc.org/view.php?id=538)
recruit jbowler and integrate thumb support
+ frv:
+ needs to be updated for the new ldso changes and unification of the
+ uClibc_main funcs (__uClibc_start_main doesnt exist anymore)
hppa:
errno.c test segfaults causes segfault in clone.S (seems to be in glibc too)
i386:
ldso is not implemented
m68k:
ldso lazy relocation doesnt work
+ sh64:
+ ldso is reasonably broken, presently requiring additional
+ coaxing/threatening.
sparc:
need a sigaction.c since common one doesnt work (signal tests)
ldso needs to be updated since it's totally broken atm
vax:
pthread support, linktime warning support (implies GAS patches),
general touchups, testing, ldso.
- frv sh64:
- need to be updated to new ldso changes and unification of the
- two uClibc_main funcs (__uClibc_start_main doesnt exist anymore)
-
-----------------------------------------------------------------------------
d) Implement glibc 'a' flag for scanf string conversions.
e) Allow use of the older non-table-based ctype functions when using
stub locale support. (smaller)
+ f) __drand48_iterate should be void
+ g) alphasort vs. versionsort. The former seems to be SVID, the latter GNU
+ i.e. reverse to what we currently do. The latter is unimplemented.
+ h) ponder removal/configs to turn off: __xpg_*, bsd_signal, dysize,
+ getw/putw, utimes,
2) Additional str{f|p}time issues.
----------------------------------
b) Write a space-efficient gettext substitute, to avoid storing large amounts
of redundant data.
