+TODO list for every uClibc release:
-------------------------------------------------
+ *) Test cris, i386, mips, mipsel, sh, x86_64, arm, armeb, and powerpc
+ with the latest LTP testsuite. Fix any regressions and post LTP
+ testsuite results for each architecture on uclibc.org.
*) Audit header files. Remove prototypes for all functions that
are not supported -- especially needed for the libm headers.
*) Audit header files. When options are disabled, also disable
them in the include files as well by checking for the proper
define from include/bits/uClibc_config.h (pulled in from features.h)
- *) Test each architecture with the latest LTP testsuite, and post
- LTP testsuite results for each architecture on uclibc.org.
+TODO list for the uClibc 0.9.31 release:
+-------------------------------------------------
+ *) merge NPTL
+ Settle cancellation
+ support arches: (- todo; + done)
+ + arm
+ + sh
+ + mips
+ - i386
+ - x86_64

+
+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.
+
- *) Hide uClibc internal symbols from our exported namespace.
+TODO list for the uClibc 1.0.0 release:
+-------------------------------------------------
+ *) glob / fnmatch tests fail
+ *) regex should pass AT&T conformance tests
+ *) Finish hiding uClibc internal symbols from our exported namespace
+ *) Add system for generating minimal system call asm wrappers that abuse
+ the C ABI to minimize amount of register/stack manipulation
*) Explicity add some sortof CONFIG_LINUX_2_2_ABI, CONFIG_LINUX_2_4_ABI
and CONFIG_LINUX_2_6_ABI type options, rather than having the abi
depend on the selected set of kernel headers. This will likely also
from ldso (such as HZ). Other stuff it currently just makes
up, which is obviously wrong. Also bits/uClibc_clk_tck.h
needs to be updated at the same time to get proper HZ values.
- *) It would nice if valgrind wouldn't complain about the atexit() malloc'd
- memory for destructors, which happens since the dynamic linker calls
- atexit(), which calls malloc() prior to valgrind starting, so valgrind
- complains because it didn't see that memory allocated.
*) poll emulation using select() for old 2.0.x uClinux kernels
in libc/sysdeps/linux/common/poll.c fails some python self-tests.
Of course, modern systems using the actuall poll() syscall work fine.
- *) Rework the build system Makefile to eliminate recursive make.
- *) Build both pic and non-pic objects where appropriate, so that
- static libs need not pay the pic size penalty.
*) 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.
TODO list for AFTER the uClibc 1.0.0 release:
-------------------------------------------------
- *) Add support for Linux 2.6.x NPTL pthreads, futexes, etc
+ *) 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
<more wishlist items here>
+Arch specific TODO:
+-------------------------------------------------
+ alpha:
+ ldso is not implemented
+ 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:
+ add support for fast system calls
+ ia64:
+ 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.
-----------------------------------------------------------------------------
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.
