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 fix the vicious cyclic multidependency of cc <-> libpth <-> loclibpth
47 libswanted <-> usethreads <-> use64bitint <-> use64bitall <->
49 make configuring+building away from source directory work (VPATH et al)
50 this is related to: cross-compilation configuring (see Todo)
51 _r support (see Todo for mode detailed description)
52 POSIX 1003.1 1996 Edition support--realtime stuff:
53 POSIX semaphores, message queues, shared memory, realtime clocks,
54 timers, signals (the metaconfig units mostly already exist for these)
55 UNIX98 support: reader-writer locks, realtime/asynchronous IO
56 IPv6 support: see RFC2292, RFC2553
59 figure out where the PV->NV->PV conversion gets it wrong at least
60 in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
61 regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
62 (?:9|8999\d+) and the like.
65 Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
66 be in some systems the only thing working as quadtype and uquadtype.
69 deprecate traditional/legacy locales?
70 How do locales work across packages?
71 figure out how to support Unicode locales
72 suggestion: integrate the IBM Classes for Unicode (ICU)
73 http://oss.software.ibm.com/developerworks/opensource/icu/project/
74 and check out also the Locale Converter:
75 http://alphaworks.ibm.com/tech/localeconverter
76 ICU is "portable, open-source Unicode library with:
77 charset-independent locales (with multiple locales simultaneously
78 supported in same thread; character conversions; formatting/parsing
79 for numbers, currencies, date/time and messages; message catalogs
80 (resources) ; transliteration, collation, normalization, and text
81 boundaries (grapheme, word, line-break))".
82 There is also 'iconv', either from XPG4 or GNU (glibc).
83 iconv is about character set conversions.
84 Either ICU or iconv would be valuable to get integrated
85 into Perl, Configure already probes for libiconv and <iconv.h>.
88 make RE engine thread-safe
89 a way to do full character set arithmetics: now one can do
90 addition, negate a whole class, and negate certain subclasses
91 (e.g. \D, [:^digit:]), but a more generic way to add/subtract/
92 intersect characters/classes, like described in the Unicode technical
93 report on Regular Expression Guidelines,
94 http://www.unicode.org/unicode/reports/tr18/
95 (amusingly, the TR notes that difference and intersection
96 can be done using "Perl-style look-ahead")
97 difference syntax? maybe [[:alpha:][^abc]] meaning
98 "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]?
99 (maybe bad, as we explicitly disallow such 'ranges')
100 intersection syntax? maybe [[..]&[...]]?
101 POSIX [=bar=] and [.zap.] would nice too but there's no API for them
102 =bar= could be done with Unicode, though, see the Unicode TR #15 about
104 http://www.unicode.org/unicode/reports/tr15/
105 this is also a part of the Unicode 3.0:
106 http://www.unicode.org/unicode/uni2book/u2.html
107 executive summary: there are several different levels of 'equivalence'
111 use fchown, fchmod (and futimes?) internally when possible
112 use fchdir(how portable?)
113 create secure reliable portable temporary file modules
114 audit the standard utilities for security problems and fix them
118 alternate runops() for signal despatch
119 figure out how to die() in delayed sighandler
120 make Thread::Signal work under useithreads
123 sort out the spawnvp() mess for system('a','b','c') compatibility
124 work out DLL versioning
127 add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?)
128 sub-second sleep()? alarm()? time()? (integrate Time::HiRes?
129 Configure doesn't yet probe for usleep/nanosleep/ualarm but
131 floating point handling: nans, infinities, fp exception masks, etc.
132 at least the following interfaces exist: fp_classify(), fp_class(),
133 class(), isnan(), isinf(), isfinite(), finite(), isnormal(),
134 ordered(), fp_setmask(), fp_getmask(), fp_setround(), fp_getround(),
135 ieeefp.h, fp_class.h. There are metaconfig units for most of these.
136 Search for ifdef __osf__ in pp.c to find a temporary fix that
137 needs to be done right.
138 fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
139 both arguments are IVs/UVs
140 replace pod2html with new PodtoHtml? (requires other modules from CPAN)
141 automate testing with large parts of CPAN
142 Unicode collation? http://www.unicode.org/unicode/reports/tr10/
143 turn Cwd into an XS module? (Configure already probes for getcwd())
144 mmap for speeding up input? (Configure already probes for the mmap family)
145 sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
146 setitimer, getitimer? (the metaconfig units exist)
149 keep filenames 8.3 friendly, where feasible
150 upgrade to newer versions of all independently maintained modules
151 comprehensive perldelta.pod
154 describe new age patterns
155 update perl{guts,call,embed,xs} with additions, changes to API
156 convert more examples to use autovivified filehandles
157 document Win32 choices
158 spot-check all new modules for completeness
159 better docs for pack()/unpack()
160 reorg tutorials vs. reference sections
