-*) Fix ldd to not multiply list libs
-*) Check cris architecture
-
-Erik's TODO list for the next release:
-
- *) When options are disabled, also disable them in the
- include files as well.
- *) Make all configured out symbols optionally add a linker warning saying
- "Hey! You are trying to use a function that you have configured out.
- If you really want to use this function, enable CONFIG_FOO and rebuild
- uClibc".
+TODO list for the uClibc 0.9.28 release:
+-------------------------------------------------
+ *) 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 1.0.0 release:
+-------------------------------------------------
+
+ *) Hide uClibc internal symbols from our exported namespace.
+ *) 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
+ require that we provide a set of kernel headers (probably a derivitive
+ of Mazur's linux-libc-headers) that can supplies the 2.2, 2.4, and 2.6
+ kernel abi.
+ *) Documentation updates:
+ *) Write a uClibc HOWTO document
+ *) Update README document
+ *) Update INSTALL document
+ *) Update docs/Glibc_vs_uClibc_Differences.txt document
+ and fully document all differences between the feature
+ set of uClibc and glibc.
+ *) Update docs/uClibc_vs_SuSv3.txt document
+ *) Update docs/threads.txt document
+ *) Write man pages for ldd and ldconfig utility binaries
+ *) Implement some mechanism (perhaps encoded in the .so name,
+ perhaps using an abi tag magically embedded into each object)
+ for flagging config options that break the ABI. Options
+ such as UCLIBC_HAS_SOFT_FLOAT, UCLIBC_HAS_THREADS, UCLIBC_HAS_LOCALE,
+ 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
+ trade off where size clearly wins).
*) Make all small objects (>~50 bytes) into either inlines or
into a static library
- *) Document all differences between the feature set of uClibc
- and glibc.
+ *) Cleanup / rewrite sysconf.c. It should get some information
+ 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 Linux 2.6.x fast vsyscalls
+ *) Enable pristine source tree builds
*) Fix regex so it isn't so stinking big
*) Fix glob so it isn't so stinking big
- *) Fix the dlopen() bug with handling of symbols that are already
- resolved. Seems if it is already resolved it ignores them rather than
- resolving the new symbol and overriding.
- *) Adapt uClibc to use Linux 2.5.x pthreads
- *) Remove all use of kernel headers (i.e. copy the needed bits
- to completely specify the per-arch kernel ABI).
- *) Fix x86 profiling. It currently only works when static + PIC...
+ *) 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.
+ <more wishlist items here>
+
+
-----------------------------------------------------------------------------
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)
-
+
2) Additional str{f|p}time issues.
----------------------------------
a) Spacing issue wrt strptime.
c) Support locale era in year designations. (data is in place)
d) Deal with mb format string issues in strftime.
e) Implement wcsftime.
-
+
3) Other locale issues (my implementation):
-------------------------------------------
a) Do a little more clean up of ctype and wctype.
b) Write a space-efficient gettext substitute, to avoid storing large amounts
of redundant data.
-
-Other stuff:
-
-Move the target-specific sysconf.c generator to extra (as it needs to be
- run on the target) and fix libc/unistd/Makefile.
-
------------------------------------------------------------------------------
-ds's list:
-
-Search for string literals that are not in the .rodata section. (Varies
-by architecture and gcc version.)
-
-man pages for binaries
-
-check compiling without FP support -- are FP instructions still generated?
-Needs a uClibc_config.h entry dependent on HAS_FLOATING_POINT.
-
-Why does ld.so search /usr/powerpc-uclibc/lib before LD_LIBRARY_PATH?
-
------------------------------------------------------------------------------
-
-Any takers?
-
-*) Documentation
- - List all differences between the feature set of uClibc and glibc.
-*) run 'nm -D --size-sort -t d libuClibc-0.9.5.so' and work on the biggest things
- (i.e. stuff at the end of the list) to make them smaller.
-*) make inb/outb work for all arches. This is complete for i386 and arm.
- Other archs like powerpc, still need fixing.
