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 UNIX98 support: reader-writer locks, realtime/asynchronous IO
52 IPv6 support: see RFC2292, RFC2553
55 figure out where the PV->NV->PV conversion gets it wrong at least
56 in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
57 regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
58 (?:9|8999\d+) and the like.
61 Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
62 be in some systems the only thing working as quadtype and uquadtype.
65 deprecate traditional/legacy locales?
66 How do locales work across packages?
67 figure out how to support Unicode locales
68 suggestion: integrate the IBM Classes for Unicode (ICU)
69 http://oss.software.ibm.com/developerworks/opensource/icu/project/
70 and check out also the Locale Converter:
71 http://alphaworks.ibm.com/tech/localeconverter
72 ICU is "portable, open-source Unicode library with:
73 charset-independent locales (with multiple locales simultaneously
74 supported in same thread; character conversions; formatting/parsing
75 for numbers, currencies, date/time and messages; message catalogs
76 (resources) ; transliteration, collation, normalization, and text
77 boundaries (grapheme, word, line-break))".
78 There is also 'iconv', either from XPG4 or GNU (glibc).
79 iconv is about character set conversions.
80 Either ICU or iconv would be valuable to get integrated
81 into Perl, Configure already probes for libiconv and <iconv.h>.
84 make RE engine thread-safe
85 a way to do full character set arithmetics: now one can do
86 addition, negate a whole class, and negate certain subclasses
87 (e.g. \D, [:^digit:]), but a more generic way to add/subtract/
88 intersect characters/classes, like described in the Unicode technical
89 report on Regular Expression Guidelines,
90 http://www.unicode.org/unicode/reports/tr18/
91 (amusingly, the TR notes that difference and intersection
92 can be done using "Perl-style look-ahead")
93 difference syntax? maybe [[:alpha:][^abc]] meaning
94 "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]?
95 (maybe bad, as we explicitly disallow such 'ranges')
96 intersection syntax? maybe [[..]&[...]]?
97 POSIX [=bar=] and [.zap.] would nice too but there's no API for them
98 =bar= could be done with Unicode, though, see the Unicode TR #15 about
100 http://www.unicode.org/unicode/reports/tr15/
101 this is also a part of the Unicode 3.0:
102 http://www.unicode.org/unicode/uni2book/u2.html
103 executive summary: there are several different levels of 'equivalence'
107 use fchown, fchmod (and futimes?) internally when possible
108 use fchdir(how portable?)
109 create secure reliable portable temporary file modules
110 audit the standard utilities for security problems and fix them
114 alternate runops() for signal despatch
115 figure out how to die() in delayed sighandler
116 make Thread::Signal work under useithreads
119 sort out the spawnvp() mess for system('a','b','c') compatibility
120 work out DLL versioning
123 add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?)
124 sub-second sleep()? alarm()? time()? (integrate Time::HiRes?
125 Configure doesn't yet probe for usleep/nanosleep/ualarm but
127 floating point handling: nans, infinities, fp exception masks, etc.
128 at least the following interfaces exist: fp_classify(), fp_class(),
129 class(), isnan(), isinf(), isfinite(), finite(), isnormal(),
130 ordered(), fp_setmask(), fp_getmask(), fp_setround(), fp_getround(),
131 ieeefp.h, fp_class.h. There are metaconfig units for most of these.
132 Search for ifdef __osf__ in pp.c to find a temporary fix that
133 needs to be done right.
134 fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
135 both arguments are IVs/UVs
136 replace pod2html with new PodtoHtml? (requires other modules from CPAN)
137 automate testing with large parts of CPAN
138 Unicode collation? http://www.unicode.org/unicode/reports/tr10/
139 turn Cwd into an XS module? (Configure already probes for getcwd())
140 mmap for speeding up input? (Configure already probes for the mmap family)
141 sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
142 setitimer, getitimer? (the metaconfig units exist)
145 keep filenames 8.3 friendly, where feasible
146 upgrade to newer versions of all independently maintained modules
147 comprehensive perldelta.pod
150 describe new age patterns
151 update perl{guts,call,embed,xs} with additions, changes to API
152 convert more examples to use autovivified filehandles
153 document Win32 choices
154 spot-check all new modules for completeness
155 better docs for pack()/unpack()
156 reorg tutorials vs. reference sections
