2 finish byte <-> utf8 and localencoding <-> utf8 conversions
3 make substr($bytestr,0,0,$charstr) do the right conversion
4 add Unicode::Map equivivalent to core
5 add support for I/O disciplines
6 - a way to specify disciplines when opening things:
7 open(F, "<:crlf :utf16", $file)
8 - a way to specify disciplines for an already opened handle:
9 binmode(STDIN, ":slurp :raw")
10 - a way to set default disciplines for all handle constructors:
11 use open IN => ":any", OUT => ":utf8", SYS => ":utf16"
12 eliminate need for "use utf8;"
13 autoload byte.pm when byte:: is seen by the parser
14 check uv_to_utf8() calls for buffer overflow
15 (see also "Locales", "Regexen", and "Miscellaneous")
18 support "use Thread;" under useithreads
20 - create new interpreter in a different thread
21 - exchange data between interpreters/threads
22 - share namespaces between interpreters/threads
23 work out consistent semantics for exit/die in threads
24 support for externally created threads?
28 auto-produce executable
29 typed lexicals should affect B::CC::load_pad
30 workarounds to help Win32
31 END blocks need saving in compiled output
33 fix comppadlist (names in comppad_name can have fake SvCUR
34 from where newASSIGNOP steals the field)
37 CPP-space: restrict what we export from headers when !PERL_CORE
38 header-space: move into CORE/perl/?
39 API-space: complete the list of things that constitute public api
42 fix the vicious cyclic multidependency of cc <-> libpth <-> loclibpth
43 libswanted <-> usethreads <-> use64bitint <-> use64bitall <->
45 make configuring+building away from source directory work (VPATH et al)
46 this is related to: cross-compilation configuring (see Todo)
47 _r support (see Todo for mode detailed description)
48 POSIX 1003.1 1996 Edition support--realtime stuff:
49 POSIX semaphores, message queues, shared memory, realtime clocks,
50 timers, signals (the metaconfig units mostly already exist for these)
51 better shadow password support: see pp_sys.c:pp_gpwent()
52 UNIX98 support: reader-writer locks, realtime/asynchronous IO
53 IPv6 support: see RFC2292, RFC2553
56 figure out where the PV->NV->PV conversion gets it wrong at least
57 in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
58 regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
59 (?:9|8999\d+) and the like.
62 Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
63 be in some systems the only thing working as quadtype and uquadtype.
66 deprecate traditional/legacy locales?
67 How do locales work across packages?
68 figure out how to support Unicode locales
69 suggestion: integrate the IBM Classes for Unicode (ICU)
70 http://oss.software.ibm.com/developerworks/opensource/icu/project/
71 ICU is "portable, open-source Unicode library with:
72 charset-independent locales (with multiple locales
73 simultaneously supported in same thread; character
74 conversions; formatting/parsing for numbers, currencies,
75 date/time and messages; message catalogs (resources);
76 transliteration, collation, normalization, and text
77 boundaries (grapheme, word, line-break))".
78 Check out also the Locale Converter:
79 http://alphaworks.ibm.com/tech/localeconverter
80 There is also the iconv interface, either from XPG4 or GNU (glibc).
81 iconv is about character set conversions.
82 Either ICU or iconv would be valuable to get integrated
83 into Perl, Configure already probes for libiconv and <iconv.h>.
86 make RE engine thread-safe
87 a way to do full character set arithmetics: now one can do
88 addition, negate a whole class, and negate certain subclasses
89 (e.g. \D, [:^digit:]), but a more generic way to add/subtract/
90 intersect characters/classes, like described in the Unicode technical
91 report on Regular Expression Guidelines,
92 http://www.unicode.org/unicode/reports/tr18/
93 (amusingly, the TR notes that difference and intersection
94 can be done using "Perl-style look-ahead")
95 difference syntax? maybe [[:alpha:][^abc]] meaning
96 "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]?
97 (maybe bad, as we explicitly disallow such 'ranges')
98 intersection syntax? maybe [[..]&[...]]?
99 POSIX [=bar=] and [.zap.] would nice too but there's no API for them
100 =bar= could be done with Unicode, though, see the Unicode TR #15 about
102 http://www.unicode.org/unicode/reports/tr15/
103 this is also a part of the Unicode 3.0:
104 http://www.unicode.org/unicode/uni2book/u2.html
105 executive summary: there are several different levels of 'equivalence'
106 trie optimization: factor out common suffixes (and prefixes?)
107 from |-alternating groups (both for exact strings and character
108 classes, use lookaheads?)
112 use fchown, fchmod (and futimes?) internally when possible
113 use fchdir(how portable?)
114 create secure reliable portable temporary file modules
115 audit the standard utilities for security problems and fix them
119 alternate runops() for signal despatch
120 figure out how to die() in delayed sighandler
121 make Thread::Signal work under useithreads
124 sort out the spawnvp() mess for system('a','b','c') compatibility
125 work out DLL versioning
128 add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?)
129 sub-second sleep()? alarm()? time()? (integrate Time::HiRes?
130 Configure doesn't yet probe for usleep/nanosleep/ualarm but
132 floating point handling: nans, infinities, fp exception masks, etc.
133 At least the following interfaces exist: fp_classify(), fp_class(),
134 class(), isinf(), isfinite(), finite(), isnormal(), unordered(),
135 <ieeefp.h>, <fp_class.h> (there are metaconfig units for all these),
136 fp_setmask(), fp_getmask(), fp_setround(), fp_getround()
137 (no metaconfig units yet for these).
138 Don't forget finitel(), fp_classl(), fp_class_l(), (yes, both do,
139 unfortunately, exist), and unorderedl().
140 As of 5.6.1 there is cpp macro Perl_isnan().
141 fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
142 both arguments are IVs/UVs
143 replace pod2html with new PodtoHtml? (requires other modules from CPAN)
144 automate testing with large parts of CPAN
145 Unicode collation? http://www.unicode.org/unicode/reports/tr10/
146 turn Cwd into an XS module? (Configure already probes for getcwd())
147 mmap for speeding up input? (Configure already probes for the mmap family)
148 sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
149 setitimer, getitimer? (the metaconfig units exist)
152 keep filenames 8.3 friendly, where feasible
153 upgrade to newer versions of all independently maintained modules
