2 Erik's TODO list for the next release:
4 1) Fix profiling support
5 2) Implement getgrgid_r and getgrnam_r, per SuSv3
6 3) When options are disabled, also disable them in the
8 4) Make all small objects (>~50 bytes) into either inlines or
10 5) Rework code that fails POSIX conformance tests
11 6) Document all differences between the feature set of uClibc
13 7) Add missing syscall() function to ports that are still
14 missing it. (x86 and arm are finished so far).
18 -----------------------------------------------------------------------------
21 In the next couple of months, I plan on completing the wide char and locale
22 support. Here's my current list of things to implement by early November.
24 1) Little things that need fixing:
25 ----------------------------------
26 a) Use locale decimal point in *printf() and strto*d() -- slightly
27 complicated by the fact that at least one locale uses a wchar
28 radix that does not map to a single byte in UTF-8.
29 b) Use locale digit grouping in *printf().
30 c) Implement %lc (%C) and %ls (%S) handling for printf.
31 d) Deal with mb format string issues in printf, scanf,
33 e) Implement wcwidth() and wcswidth() -- use Markus Kuhn's versions.
35 2) Implement wide char numeric conversion functions -- wcsto*().
36 ----------------------------------------------------------------
37 These should be relatively minor modifications to the corresponding
38 strto*() functions, unless locale specific alternate digit support
41 3) Implement wide formatted output -- *wprintf():
42 -------------------------------------------------
43 The stream output variants should be easily created by appropriately
44 modifying the char *printf() functions.
46 The string buffer variants may take some time to implement because
47 they need to store wchars in a buffer. It will be necessary to hack
48 the core stdio code slightly to support this.
50 4) Reimplement scanf for narrow and wide streams.
51 -------------------------------------------------
52 The current char version of scanf() needs some cleanup. Also,
53 modifying the char version of scanf() to create the wchar versions
54 will require reworking the implementation of matching char sets
57 Also, as with *wprintf() above, the string buffer variants of wscanf()
58 may require some additional work to the core stdio code.
60 5) Additional str{f|p}time issues.
61 ----------------------------------
62 Support locale specific alternate digits.
63 Support locale era in year designations.
65 6) Other locale issues (my implementation):
66 -------------------------------------------
67 a) Clean up locale code to make building easier. Fix alt_digits.
68 (Note: This is only _clean_up_ of the current stuff in extra/locale
69 so that it can be cross-compiled, etc. I'm not talking about the
70 complete rewrite that should really be done.)
71 b) Additional clean up of ctype and wctype.
72 c) Implement collation support for char and wchar -- *xfrm() and *coll().
73 d) transliteration of unsupported wchars in 8-bit locales (like glibc).
78 Reimplement _dtostr to correct its deficiencies (%A support!) and hopefully
81 Move the target-specific sysconf.c generator to extra (as it needs to be
82 run on the target) and fix libc/unistd/Makefile.
84 Make errno and endptr handling the default in the strto* functions and
85 document how to turn those off to save space.
87 -----------------------------------------------------------------------------
90 Search for string literals that are not in the .rodata section. (Varies
91 by architecture and gcc version.)
93 man pages for binaries
95 add obstack stuff for gettext (?)
97 check compiling without FP support -- are FP instructions still generated?
98 Needs a uClibc_config.h entry dependent on HAS_FLOATING_POINT.
100 Why does ld.so search /usr/powerpc-uclibc/lib before LD_LIBRARY_PATH?
102 -----------------------------------------------------------------------------
106 *) Fix regex so it isn't so stinking big
107 *) Fix glob so it isn't so stinking big
109 - List all differences between the feature set of uClibc and glibc.
110 *) run 'nm -D --size-sort -t d libuClibc-0.9.5.so' and work on the biggest things
111 (i.e. stuff at the end of the list) to make them smaller.
112 *) make inb/outb work for all arches. This is complete for i386 and arm.
113 Other archs like powerpc, still need fixing.
115 -----------------------------------------------------------------------------
120 bits/dirent.h currently differs from the glibc version (d_type unsupported)
