1 | Unicode support |
d1edabcf |
2 | finish byte <-> utf8 and localencoding <-> utf8 conversions |
3 | make substr($bytestr,0,0,$charstr) do the right conversion |
6dd11d31 |
4 | add Unicode::Map equivivalent to core |
5 | add support for I/O disciplines |
d1edabcf |
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" |
6dd11d31 |
12 | eliminate need for "use utf8;" |

13 | autoload byte.pm when byte:: is seen by the parser |

17 | Multi-threading |
6dd11d31 |
18 | support "use Thread;" under useithreads |
19 | add mechanism to: |
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? |
25 | Thread::Pool? |

31 | END blocks need saving in compiled output |
32 | _AUTOLOAD prodding |

33 | fix comppadlist (names in comppad_name can have fake SvCUR |
34 | from where newASSIGNOP steals the field) |

36 | Namespace cleanup |

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 <-> |
44 | uselargefiles <-> ... |

45 | make configuring+building away from source directory work (VPATH et al) |
d57b1ce7 |
46 | this is related to: cross-compilation configuring (see Todo) |
da44fe2a |
47 | _r support (see Todo for mode detailed description) |
1d82895f |
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 |
da44fe2a |
52 | IPv6 support: see RFC2292, RFC2553 |

54 | Long doubles |
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 |
55f6b6ec |
57 | regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t, |
58 | (?:9|8999\d+) and the like. |
59 | |
60 | 64-bit support |
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. |

64 | Locales |
6dd11d31 |
65 | deprecate traditional/legacy locales? |
8bce6328 |
66 | How do locales work across packages? |
6dd11d31 |
67 | figure out how to support Unicode locales |
1d82895f |
68 | suggestion: integrate the IBM Classes for Unicode (ICU) |
8bce6328 |
69 | http://oss.software.ibm.com/developerworks/opensource/icu/project/ |
1d82895f |
70 | and check out also the Locale Converter: |
71 | http://alphaworks.ibm.com/tech/localeconverter |
8bce6328 |
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 |
fe32fb73 |
81 | into Perl, Configure already probes for libiconv and <iconv.h>. |

83 | Regexen |
6dd11d31 |
84 | make RE engine thread-safe |
e620704b |
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 [[..]&[...]]? |
b8c5462f |
97 | POSIX [=bar=] and [.zap.] would nice too but there's no API for them |
1d82895f |
98 | =bar= could be done with Unicode, though, see the Unicode TR #15 about |
99 | normalization forms: |
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' |

104 | approximate matching |

106 | Security |
107 | use fchown, fchmod (and futimes?) internally when possible |
108 | use fchdir(how portable?) |
fe32fb73 |
109 | create secure reliable portable temporary file modules |
110 | audit the standard utilities for security problems and fix them |

122 | Miscellaneous |
0ff51efc |
123 | add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?) |
fe32fb73 |
124 | sub-second sleep()? alarm()? time()? (integrate Time::HiRes? |
125 | Configure doesn't yet probe for usleep/nanosleep/ualarm but |
126 | the units exist) |
127 | floating point handling: nans, infinities, fp exception masks, etc. |
a3540c92 |
128 | At least the following interfaces exist: fp_classify(), fp_class(), |
129 | class(), isinf(), isfinite(), finite(), isnormal(), unordered(), |
130 | <ieeefp.h>, <fp_class.h> (there are metaconfig units for all these), |
131 | fp_setmask(), fp_getmask(), fp_setround(), fp_getround() |
132 | (no metaconfig units yet for these). |
133 | Don't forget finitel(), fp_classl(), fp_class_l(), (yes, both do, |
134 | unfortunately, exist), and unorderedl(). |
135 | As of 5.6.1 there is cpp macro Perl_isnan(). |
fe32fb73 |
136 | fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if |
137 | both arguments are IVs/UVs |
6dd11d31 |
138 | replace pod2html with new PodtoHtml? (requires other modules from CPAN) |
245ccdfc |
139 | automate testing with large parts of CPAN |
fe32fb73 |
140 | Unicode collation? http://www.unicode.org/unicode/reports/tr10/ |
141 | turn Cwd into an XS module? (Configure already probes for getcwd()) |
142 | mmap for speeding up input? (Configure already probes for the mmap family) |
143 | sendmsg, recvmsg? (Configure doesn't probe for these but the units exist) |
55f6b6ec |
144 | setitimer, getitimer? (the metaconfig units exist) |
