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 scenarios to consider: the host and the target might have
52 shared filesystems, or they might not (the communication
53 channel might be e.g. rsh/ssh, or some batch submission system)
54 most obviously: they might not share the same CPU
55 meaning: assume nothing about shared properties/resources
56 _r support (see Todo for mode detailed description)
57 POSIX 1003.1 1996 Edition support--realtime stuff:
58 POSIX semaphores, message queues, shared memory, realtime clocks,
59 timers, signals (the metaconfig units mostly already exist for these)
60 UNIX98 support: reader-writer locks, realtime/asynchronous IO
61 IPv6 support: see RFC2292, RFC2553
64 figure out where the PV->NV->PV conversion gets it wrong at least
65 in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
66 regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
67 (?:9|8999\d+) and the like.
70 Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
71 be in some systems the only thing working as quadtype and uquadtype.
74 deprecate traditional/legacy locales?
75 How do locales work across packages?
76 figure out how to support Unicode locales
77 suggestion: integrate the IBM Classes for Unicode (ICU)
78 http://oss.software.ibm.com/developerworks/opensource/icu/project/
79 and check out also the Locale Converter:
80 http://alphaworks.ibm.com/tech/localeconverter
81 ICU is "portable, open-source Unicode library with:
82 charset-independent locales (with multiple locales simultaneously
83 supported in same thread; character conversions; formatting/parsing
84 for numbers, currencies, date/time and messages; message catalogs
85 (resources) ; transliteration, collation, normalization, and text
86 boundaries (grapheme, word, line-break))".
87 There is also 'iconv', either from XPG4 or GNU (glibc).
88 iconv is about character set conversions.
89 Either ICU or iconv would be valuable to get integrated
90 into Perl, Configure already probes for libiconv and <iconv.h>.
93 make RE engine thread-safe
94 POSIX [=bar=] and [.zap.] would nice too but there's no API for them
95 =bar= could be done with Unicode, though, see the Unicode TR #15 about
97 http://www.unicode.org/unicode/reports/tr15/
98 this is also a part of the Unicode 3.0:
99 http://www.unicode.org/unicode/uni2book/u2.html
100 executive summary: there are several different levels of 'equivalence'
104 use fchown, fchmod (and futimes?) internally when possible
105 use fchdir(how portable?)
106 create secure reliable portable temporary file modules
107 audit the standard utilities for security problems and fix them
111 alternate runops() for signal despatch
112 figure out how to die() in delayed sighandler
113 make Thread::Signal work under useithreads
116 sort out the spawnvp() mess for system('a','b','c') compatibility
117 work out DLL versioning
120 add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?)
121 sub-second sleep()? alarm()? time()? (integrate Time::HiRes?
122 Configure doesn't yet probe for usleep/nanosleep/ualarm but
124 floating point handling: nans, infinities, fp exception masks, etc.
125 at least the following interfaces exist: fp_classify(), fp_class(),
126 class(), isnan(), isinf(), isfinite(), finite(), isnormal(),
127 ordered(), fp_setmask(), fp_getmask(), fp_setround(), fp_getround(),
128 ieeefp.h, fp_class.h. There are metaconfig units for most of these.
129 Search for ifdef __osf__ in pp.c to find a temporary fix that
130 needs to be done right.
131 fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
132 both arguments are IVs/UVs
133 replace pod2html with new PodtoHtml? (requires other modules from CPAN)
134 automate testing with large parts of CPAN
135 Unicode collation? http://www.unicode.org/unicode/reports/tr10/
136 turn Cwd into an XS module? (Configure already probes for getcwd())
137 mmap for speeding up input? (Configure already probes for the mmap family)
138 sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
139 setitimer, getitimer? (the metaconfig units exist)
142 keep filenames 8.3 friendly, where feasible
143 upgrade to newer versions of all independently maintained modules
144 comprehensive perldelta.pod
147 describe new age patterns
148 update perl{guts,call,embed,xs} with additions, changes to API
149 convert more examples to use autovivified filehandles
150 document Win32 choices
151 spot-check all new modules for completeness
152 better docs for pack()/unpack()
153 reorg tutorials vs. reference sections
