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 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.
- *) Fix it so valgrind 2.4.0 no longer complains about the memory mmaped
- and used by ldso. Currently it whines on basically about virtually
- every function call when doing default lazy binding, which makes its
- output virtually useless due to the excess noise.

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
- *) fold NPTL branch back into trunk
- *) as many of the arch-specific issues as possible
-
+ *) 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.
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.
+ *) 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
*) 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 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
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
- mips:
- brk/pipe fixes: http://bugs.uclibc.org/view.php?id=469
+ 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.
- bfin cris rfv 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.
