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
51 host vs target: compile in the host, get the executable to the target,
52 get the possible input files to the target, execute in the target,
53 get possible output files back to to host. this needs to work
54 both during Configure and during the build. You cannot assume
55 shared filesystems between the host and the target, executing
56 the target executable may involve e.g. rsh
57 _r support (see Todo for mode detailed description)
58 POSIX 1003.1 1996 Edition support--realtime stuff:
59 POSIX semaphores, message queues, shared memory, realtime clocks,
60 timers, signals (the metaconfig units mostly already exist for these)
61 UNIX98 support: reader-writer locks, realtime/asynchronous IO
62 IPv6 support: see RFC2292, RFC2553
65 figure out where the PV->NV->PV conversion gets it wrong at least
66 in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
67 regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
68 (?:9|8999\d+) and the like.
71 Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
72 be in some systems the only thing working as quadtype and uquadtype.
75 deprecate traditional/legacy locales?
76 How do locales work across packages?
77 figure out how to support Unicode locales
78 suggestion: integrate the IBM Classes for Unicode (ICU)
79 http://oss.software.ibm.com/developerworks/opensource/icu/project/
80 and check out also the Locale Converter:
81 http://alphaworks.ibm.com/tech/localeconverter
82 ICU is "portable, open-source Unicode library with:
83 charset-independent locales (with multiple locales simultaneously
84 supported in same thread; character conversions; formatting/parsing
85 for numbers, currencies, date/time and messages; message catalogs
86 (resources) ; transliteration, collation, normalization, and text
87 boundaries (grapheme, word, line-break))".
88 There is also 'iconv', either from XPG4 or GNU (glibc).
89 iconv is about character set conversions.
90 Either ICU or iconv would be valuable to get integrated
91 into Perl, Configure already probes for libiconv and <iconv.h>.
94 make RE engine thread-safe
95 a way to do full character set arithmetics: now one can do
96 addition, negate a whole class, and negate certain subclasses
97 (e.g. \D, [:^digit:]), but a more generic way to add/subtract/
98 intersect characters/classes, like described in the Unicode technical
99 report on Regular Expression Guidelines,
100 http://www.unicode.org/unicode/reports/tr18/
101 (amusingly, the TR notes that difference and intersection
102 can be done using "Perl-style look-ahead")
103 difference syntax? maybe [[:alpha:][^abc]] meaning
104 "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]?
105 (maybe bad, as we explicitly disallow such 'ranges')
106 intersection syntax? maybe [[..]&[...]]?
107 POSIX [=bar=] and [.zap.] would nice too but there's no API for them
108 =bar= could be done with Unicode, though, see the Unicode TR #15 about
110 http://www.unicode.org/unicode/reports/tr15/
111 this is also a part of the Unicode 3.0:
112 http://www.unicode.org/unicode/uni2book/u2.html
113 executive summary: there are several different levels of 'equivalence'
117 use fchown, fchmod (and futimes?) internally when possible
118 use fchdir(how portable?)
119 create secure reliable portable temporary file modules
120 audit the standard utilities for security problems and fix them
124 alternate runops() for signal despatch
125 figure out how to die() in delayed sighandler
126 make Thread::Signal work under useithreads
129 sort out the spawnvp() mess for system('a','b','c') compatibility
130 work out DLL versioning
133 add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?)
134 sub-second sleep()? alarm()? time()? (integrate Time::HiRes?
135 Configure doesn't yet probe for usleep/nanosleep/ualarm but
137 floating point handling: nans, infinities, fp exception masks, etc.
138 at least the following interfaces exist: fp_classify(), fp_class(),
139 class(), isnan(), isinf(), isfinite(), finite(), isnormal(),
140 ordered(), fp_setmask(), fp_getmask(), fp_setround(), fp_getround(),
141 ieeefp.h, fp_class.h. There are metaconfig units for most of these.
142 Search for ifdef __osf__ in pp.c to find a temporary fix that
143 needs to be done right.
144 fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
145 both arguments are IVs/UVs
146 replace pod2html with new PodtoHtml? (requires other modules from CPAN)
147 automate testing with large parts of CPAN
148 Unicode collation? http://www.unicode.org/unicode/reports/tr10/
149 turn Cwd into an XS module? (Configure already probes for getcwd())
150 mmap for speeding up input? (Configure already probes for the mmap family)
151 sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
152 setitimer, getitimer? (the metaconfig units exist)
155 keep filenames 8.3 friendly, where feasible
156 upgrade to newer versions of all independently maintained modules
157 comprehensive perldelta.pod
160 describe new age patterns
161 update perl{guts,call,embed,xs} with additions, changes to API
162 convert more examples to use autovivified filehandles
163 document Win32 choices
164 spot-check all new modules for completeness
