2 fix small memory leaks on compile-time failures
5 finish byte <-> utf8 and localencoding <-> utf8 conversions
6 make substr($bytestr,0,0,$charstr) do the right conversion
7 add Unicode::Map equivivalent to core
8 add support for I/O disciplines
9 - a way to specify disciplines when opening things:
10 open(F, "<:crlf :utf16", $file)
11 - a way to specify disciplines for an already opened handle:
12 binmode(STDIN, ":slurp :raw")
13 - a way to set default disciplines for all handle constructors:
14 use open IN => ":any", OUT => ":utf8", SYS => ":utf16"
15 eliminate need for "use utf8;"
16 autoload utf8_heavy.pl's swash routines in swash_init()
17 autoload byte.pm when byte:: is seen by the parser
18 check uv_to_utf8() calls for buffer overflow
19 (see also "Locales", "Regexen", and "Miscellaneous")
22 support "use Thread;" under useithreads
24 - create new interpreter in a different thread
25 - exchange data between interpreters/threads
26 - share namespaces between interpreters/threads
27 work out consistent semantics for exit/die in threads
28 support for externally created threads?
32 auto-produce executable
33 typed lexicals should affect B::CC::load_pad
34 workarounds to help Win32
35 END blocks need saving in compiled output
37 fix comppadlist (names in comppad_name can have fake SvCUR
38 from where newASSIGNOP steals the field)
41 CPP-space: restrict what we export from headers when !PERL_CORE
42 header-space: move into CORE/perl/?
43 API-space: complete the list of things that constitute public api
46 make configuring+building away from source directory work (VPATH et al)
48 cross-compilation configuring
49 POSIX 1003.1 1996 Edition support--realtime stuff:
50 POSIX semaphores, message queues, shared memory, realtime clocks,
51 timers, signals (the metaconfig units mostly already exist for these)
52 UNIX98 support: reader-writer locks, realtime/asynchronous IO
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 POSIX [=bar=] and [.zap.] would nice too but there's no API for them
86 =bar= could be done with Unicode, though, see the Unicode TR #15 about
88 http://www.unicode.org/unicode/reports/tr15/
89 this is also a part of the Unicode 3.0:
90 http://www.unicode.org/unicode/uni2book/u2.html
91 executive summary: there are several different levels of 'equivalence'
95 use fchown, fchmod (and futimes?) internally when possible
96 use fchdir(how portable?)
97 create secure reliable portable temporary file modules
98 audit the standard utilities for security problems and fix them
102 alternate runops() for signal despatch
103 figure out how to die() in delayed sighandler
104 make Thread::Signal work under useithreads
107 sort out the spawnvp() mess for system('a','b','c') compatibility
108 work out DLL versioning
111 add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?)
112 sub-second sleep()? alarm()? time()? (integrate Time::HiRes?
113 Configure doesn't yet probe for usleep/nanosleep/ualarm but
115 floating point handling: nans, infinities, fp exception masks, etc.
116 at least the following interfaces exist: fp_classify(), fp_class(),
117 class(), isnan(), isinf(), isfinite(), finite(), isnormal(),
118 ordered(), fp_setmask(), fp_getmask(), fp_setround(), fp_getround(),
119 ieeefp.h, fp_class.h. There are metaconfig units for most of these.
120 Search for ifdef __osf__ in pp.c to find a temporary fix that
121 needs to be done right.
122 fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
123 both arguments are IVs/UVs
124 replace pod2html with new PodtoHtml? (requires other modules from CPAN)
125 automate testing with large parts of CPAN
126 Unicode collation? http://www.unicode.org/unicode/reports/tr10/
127 turn Cwd into an XS module? (Configure already probes for getcwd())
128 mmap for speeding up input? (Configure already probes for the mmap family)
129 sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
130 setitimer, getitimer? (the metaconfig units exist)
133 keep filenames 8.3 friendly, where feasible
134 upgrade to newer versions of all independently maintained modules
135 comprehensive perldelta.pod
138 describe new age patterns
139 update perl{guts,call,embed,xs} with additions, changes to API
140 convert more examples to use autovivified filehandles
141 document Win32 choices
142 spot-check all new modules for completeness
143 better docs for pack()/unpack()
144 reorg tutorials vs. reference sections
